SAN DIEGO -- Increases in factors associated with fatty liver disease may be leading clinicians to discard more donated organs, researcher found.

In an analysis of data from the United Organ Sharing Network (UNOS), age, obesity, diabetes, and hypertension were associated with an increased risk of a liver being discarded, Eric Orman, MD, of the University of North Carolina at Chapel Hill, and colleagues reported during a press briefing at Digestive Disease Week here.

"We're actually throwing out livers that in the past may have been able to be used ... [because] of all these factors associated with fatty liver disease," Orman explained.

Orman said that over the past few years, there's been a decline in the number of liver transplants done, but that drop isn't explained by flat donation rates alone.

"Although donation rates have decreased overall, they haven't decreased to the same extent as the decline in the number of livers transplanted," he said, adding that one explanation may be an increase in discard rates due to poor quality of organs.

So he and colleagues conducted a retrospective study of data from UNOS between 1994 and 2010 totaling 93,232 organ donors. Living donors, split livers, and donors with a body mass index of less than 14 or more than 50 kg/m were excluded.

Among the nearly 94,000 donors, 75% of livers were transplanted and a quarter of livers were not used.

They found that the number of discarded organs was stable until 2003 (with a total of 1,058 organs discarded in that last year), and then rose to 1,828 by 2010.

In a bivariate analysis, they found that discarded livers more often came from donors who were older (median 49 versus 43 years), obese (35% verses 22% of non-obese donors), diabetic (35% versus 24% of nondiabetics), and hypertensive (31% versus 22% of normotensive patients).

Discard rates were also higher in donation after cardiac death, which is different from standard procurement. In the latter, a patient is declared brain dead but kept on a ventilator to keep the organs perfused (65% versus 22%). In donation after cardiac death, perfusion of blood to the organs is disrupted.

In multivariate analysis, the researchers found that all of the previous factors were associated with a liver being discarded:

  • Age (OR 1.03 for each year increase, 95% CI 1.03­ to 1.04)
  • Obesity (OR 1.92, 95% CI 1.82 to ­2.03)
  • Diabetes (OR 1.42, 95% CI 1.32 to ­1.53)
  • Hypertension (OR 1.15, 95% CI 1.08­ to 1.22)
  • Donation after cardiac death (OR 12.3, 95% CI 11.3 to ­13.4)

The researchers also saw significant increases in median donor age (40 to 46) and the prevalence of obesity (13% to 31%) during the study period, along with significant increases in diabetes (3% to 13%), hypertension (22% to 39%), and donation after cardiac death (2% to 12%).

They estimated that in 2010, 44% of discards were due to increased age, 9% to obesity, 5% to diabetes, and 5% to hypertension. These proportions were stable over time, they said.

On the other hand, the proportion of livers discarded due to donation after cardiac death rose from 0.2% in 2000 to 26% in 2010, suggesting an increasing reluctance to use these grafts, they reported.

Orman said that, overall, the findings are important "because if these trends continue, we're going to see further declines in liver transplant."

Kenneth Andreoni, MD, a UNOS committee member, said the increasing prevalence of comorbidities in donors is a "double-edged sword" because it reflects the fact that public health messages about safety are getting through to younger people, even though that may mean fewer quality donors.

"We're seeing fewer young people dying in traumas, but we're getting less high-quality, excellent organs," Andreoni told MedPage Today. "The question is, how can we make the best use of more middle-age and older donors?"

When it comes to organs with fatty liver disease, some researchers have been trying to better quantify the type of fat in the liver so that surgeons can have a better idea of what's usable and what's not, said Andreoni, who is from Ohio State University in Columbus.

Improvements on the pathology side may also be needed, he said. For instance, pathologists may need to offer a more specific range in terms of the percentage of fat in the organ, so clinicians can more easily recognize if an organ needs to be discarded or not.

Other work has focused on whether there are better ways to protect a fatty liver so it has a better chance of working after it's transplanted. "Is there something you can put in during reperfusion, like an antioxidant, that will lead to better outcomes?" Andreoni said.

A co-author reported a relationship with Salix Pharmaceuticals.

Statins Reduce Cirrhosis Deaths

DDW2012

SAN DIEGO -- Giving statins to cirrhosis patients with heart disease appears to lower the risk of both hepatic decompensation and mortality, researchers said here.

In a small, retrospective study, significantly fewer cirrhosis patients on statins had decompensation compared with cirrhosis patients not on the cholesterol-lowering drugs (38.2% versus 50.62%, P=0.018), Sonal Kumar, MD, of Brigham & Women's Hospital in Boston, and colleagues reported at Digestive Disease Week here.

They also had significantly less mortality (P=0.043), she reported.

"Contrary to the prior belief that statins aren't safe in patients with cirrhosis, we found they actually may be beneficial in this population," Kumar said during a press briefing.

Clinicians have long been concerned that statins aren't safe in patients with severe liver disease, primarily because statins are metabolized in the liver and may put patients at greater risk of complications such as hepatic decompensation and liver failure.

Recent studies, however, have suggested that statins aren't harmful in these patients, and that they may even diminish morbidity and mortality for liver patients with heart disease, Kumar said.

So she and colleagues looked at data from the Partners Research Patient Data Registry on a total of 243 patients, 81 of whom were treated for dyslipidemia with statins for at least 3 months, and 162 who served as controls matched for age, gender, and liver disease severity.

The primary outcome was hepatic decompensation, defined as the development of ascites, jaundice, hepatic encephalopathy, or variceal hemorrhage.

The statin group was followed for a mean of 1,756 days and the control group for 1,503 days.

In each group, 70.4% of patients were Child-Pugh A and 29.6% were Child-Pugh B/C; factors such as MELD, albumin, presence of varices and beta-blocker use weren't significantly different between groups.

In multivariate analysis, statin therapy alone was significantly associated with a lower risk of decompensation, they reported (HR 0.44, 95% CI 0.27 to 0.71).

In addition, analyses showed an overall longer time to decompensation in patients on statins, they found (P=0.01), which was also present for patients with Child-Pugh A disease (P=0.04).

Kumar and colleagues also found that there was less all-cause mortality among cirrhotic patients on statins compared with those not on the drugs (37% versus 50.6%, P=0.043).

In multivariate analyses, statin use was significantly associated with lower mortality (OR 0.49, 95% CI 0.29 to 0.81). Coronary artery disease and non-alcoholic steatohepatitis, on the other hand, were associated with increased mortality, they reported (OR 2.62, 95% CI 1.78 to 3.86 and OR 1.61, 95% CI 1.03 to 2.52, respectively).

The researchers also saw a longer time to death in patients with Child-Pugh A disease who used statins (P=0.005).

Kumar said the beneficial effects on liver outcomes may be due to statins' ability to diminish portal pressure, which is associated with complications including jaundice and vomiting blood due to enlarged veins in the upper GI tract. That may be mediated via statins' known mechanism of increasing the production of nitric oxide, Kumar said.

She added that more prospective trials are needed, but Zobair Younossi, MD, of Inova Health System in Great Falls, Va., who attended the press briefing at which the data were presented, said evidence is amassing that statins are safe in liver disease patients.

"If you need to use them, you should use them, and not worry about the liver," Younossi said.

But Cam Patterson, MD, of the University of North Carolina at Chapel Hill, said in an email to MedPage Today that most physicians still have "second and third thoughts about using statins in patients with severe liver disease."

"This is a retrospective, nonrandomized study, so it would be a big mistake to use this study as a general advertisement that statins can be safely used in patients with severe liver disease or that patients with liver disease will do better and live longer if they receive statins," Patterson wrote.

"What this study does tell us," he added, "is that carefully selected patients with liver disease can be given statins and that they seem to tolerate them well."

Questions that still need to be answered before making broad recommendations for the use of statins in cirrhotic patients include assessing which patients will benefit most and finding out whether patients fare better with some statins more than others, Patterson said: "I hope that this small study provides an impetus for additional studies that will answer these questions."

Kumar reported no conflicts of interest.

Herbal, Body Building, Diet Supplements Linked To Severe Liver Damage, Study

Even though supplements account for 18 percent of all liver injuries in the U.S. and their potential side effects and hepatotoxicity of supplements are still not well defined, nearly 4 out of 10 Americans take them. (David Gray/Reuters)

People taking body-building, weight-loss pills and other types of dietary and herbal supplements may be at risk for liver injury severe enough to warrant an organ transplant, experts warned.

By Christine Hsu | May 22, 2012

People taking body-building, weight-loss pills and other types of dietary and herbal supplements may be at risk for liver injury severe enough to warrant an organ transplant, experts warned at a press briefing at Digestive Disease Week in San Diego.

Even though supplements account for 18 percent of all liver injuries in the U.S. and their potential side effects and hepatotoxicity of supplements are still not well defined, nearly 4 out of 10 Americans take them.

"The number of cases in our network has increased over the years," Serrano said during the briefing. "There were no deaths, but 7% of patients needed a liver transplant. These are not trivial consequences," Dr. Jose Serrano of the National Institutes of Health said at the conference, according to Medpage Today.

According to the latest research from the U.S. Drug Induced Liver Injury Network, which evaluated patient information from eight locations across the U.S. from 2003 to 2011, dietary supplements used for body building and weight loss are the most common of any supplements to cause liver injury.

Serrano said that out of the 679 liver injury cases analyzed, 93 of the cases were caused by patients taking herbal or dietary supplements, adding that many of these patients were often younger than those who have similar liver injuries caused by other medications.

Among patients who had liver damage caused by supplements, 33 percent of them used them for body building, 26 percent for weight loss, and the remaining 31 percent used a variety of other supplements.

While the symptoms of liver injury caused by dietary or herbal supplements weren’t much different from injuries caused by other medications, researchers noted that one factor that distinguished liver injury from body building and supplements over drugs were itching, which occurred in more than 80 percent of the patients.

Around 66 percent of the patients in the study had to be hospitalized and 11 percent had developed abnormal liver function that lasted for more than 6 months.

While more than half of patients were only taking one type of supplement, 23 percent of patients used two or more supplements and 16 percent of patients look at least one supplement along with prescription drugs.

"There is so little regulation of the many products on the market," lead researcher Dr. Victor Navarro, professor at Thomas Jefferson University in Philadelphia, said in a meeting news release. "We couldn't possibly begin to figure out which products to target first without doing this research."

Dr. Donald Jensen of the University of Chicago warned that the biggest risk to patients that use supplements is not reporting it to a healthcare professional.

"Patients need to be label readers," Jensen told MedPage Today. "They can't just assume that everything out there is safe. There are things out there that can be potentially damaging."

He added that most patients may think that supplements "are food or that they're very safe. And there are some herbal medicines that probably are safe and may even do some benefit for people. I don't want to throw everything in the trash can. But, on the other hand, there are enough [supplements] that are damaging."

While not all people react negatively to supplements, Jensen said that there needs to be more research on potential patient interactions with herbal supplements.

"I don't think we're going to stop people from taking herbal medicines," he said. "I'd like to see the FDA regulate the toxic ones better, but otherwise I think the important next step is some scientific understanding of why some people get damaged and others don't."

Liver disease and recovery research at UF garners $1.3 million grant

Capture

Filed under Health, Research on Thursday, May 24, 2012.

GAINESVILLE, Fla. — University of Florida researchers have received nearly $1.3 million from the National Institute of Diabetes and Digestive and Kidney Diseases to uncover ways to lessen liver damage by studying the body’s natural process for breaking down and removing injured cells.

During surgery or transplantation, surgeons stop blood flow to the liver, temporarily cutting off oxygen and nutrients. When blood rushes back to the organ afterward it often causes serious damage called ischemia/reperfusion injury.

Finding a way to boost cells’ natural cleanup process, — and with it, older livers’ ability to recover from such stress-related injury — would help patients recover after liver surgery. It could also increase the number of livers available for people on the transplant waiting list by reducing damage to the organs of potential donors, and may lead to therapies for other diseases such as cancer and neurological disorders.

“All diseases, including liver disorders, are the consequence of multiple, complicated changes in the body,” said principal investigator Jae-Sung Kim, an assistant professor of surgery in the UF College of Medicine. “I think the way to cure diseases is to fully understand complicated mechanisms. We can take advantage of our natural defense mechanism that was evolutionally developed to fight against many causes of illness.”

More than 16,000 people in the United States await liver transplants, according to the U.S. Department of Health and Human Services’ Organ Procurement and Transplantation Network. Only 7 percent of all liver donations since 1988 have come from people older than 65, despite the fact that they die at higher rates than people in other age groups.

The multidisciplinary UF research team, which includes principal investigator Christiaan Leeuwenburgh, chief of the biology of aging division in the department of aging and geriatric research, seeks to confirm earlier findings that the liver’s ability to recover from ischemia/reperfusion injury is linked to the process by which cells remove structures called mitochondria when they are damaged. Mitochondria provide the cell with energy.

They also found that the older livers are, the slower they are at responding to stress-related damage, partly because of lowered levels of a protein responsible for directing the cell clean-up process. Injured cells resumed normal activity when inundated with the protein, called Atg4B.

The researchers will study older mice to examine age-related changes in the cell clean-up process. They also will explore ways to boost that process and examine the resulting effect on damaged livers.

“There are many studies that have investigated liver injury in younger animals and mechanisms there, but these studies are unique because they’re studying older animals,” said Leeuwenburgh a member of the UF Institute on Aging. “Most liver injuries occur and liver resection interventions are done in older individuals.”

Knowing more about how the cell clean-up process works could pave the way for new therapies, not just for liver disease, but also for a variety of other illnesses.

“Growing evidence indicates that dysfunctional or impaired autophagy, cells’ natural clean-up process, is directly associated with various diseases, including autoimmune diseases, cancer, neurological disorders and diabetes,” Kim said. “Through this study, we would like to better understand basic molecular mechanisms of autophagy.”

CDC Invites Public Comment on Draft Recommendations for One-Time Hepatitis C Testing for Baby Boomers

John-Ward_001F-090723

Dr. John Ward

HIV Policy & ProgramsMay 24, 2012

By John W. Ward, M.D., Director, Division of Viral Hepatitis, National Center for HIV/AIDS, Viral Hepatitis, STD, and TB Prevention, CDC

CDC has released draft recommendations proposing that all Americans born from 1945 through 1965 (“baby boomers”) get a one-time test for the hepatitis C virus. In the United States, hepatitis C is the leading cause of liver transplants and liver cancer, which is the fastest-rising cause of cancer-related deaths in the nation. More than 2 million U.S. baby boomers are infected with hepatitis C, accounting for more than 75 percent of all American adults living with the virus. Baby boomers are five times more likely to be infected than other adults. Most of them, though, do not know that they have the virus because hepatitis C can damage the liver for many years without noticeable symptoms. More than 15,000 Americans—mostly baby boomers—die each year from hepatitis C-related illness, such as cirrhosis and liver cancer, and deaths have been increasing steadily for over a decade.

CDC estimates one-time hepatitis C testing of baby boomers could identify more than 800,000 additional people with hepatitis C and save more than 120,000 lives. CDC believes the expanded screening efforts are needed to increase the proportion of persons with hepatitis C who are diagnosed, and referred to care to slow or halt progression of the disease and avoid transmission to others. New treatments are now available that can cure up to 75% of infections, and even more promising treatments are expected in the near future. CDC believes that expanded screening efforts can prevent thousands of unnecessary deaths from hepatitis C.

CDC’s new recommendations augment current hepatitis C testing guidelines that call for testing individuals with a known risk for the disease. Studies have found that most persons do not perceive themselves to be at risk and are not screened. CDC’s recommendations propose that a one-time blood test for hepatitis C should become a standard part of medical care for all persons born from 1945 through 1965.

In a May 22, 2012 Federal Register Notice, CDC formally invited public comment on this draft recommendation. We encourage you to review and comment on these important proposed recommendations which will be available for public comment through June 8 on www.regulations.gov, docket number CDC-2012-0005. Public comment will be used to inform the final recommendations, which will be finalized later this year.

For more information, see this factsheet (PDF 374KB) on the proposed testing recommendations.

A priceless journey: Friend’s birthday poem turned into a children’s storybook to help those dealing with cancer

Friend’s birthday poem turned into a children’s storybook to help those dealing with cancer.

By ROXIE HAMMILL
Special to The Star

It began as a birthday present—a poem written by Laura Myer for her good friend Lori Lober, who at one time had been given only a 2 to 3 percent chance of living five years.

But for much longer than that, Lober’s cancer has been kept at bay. So has the hepatitis C that Myer contracted. But the poem has blossomed into a self-published book, “Princess Elle and her Isle of Capri.” The illustrated storybook, which came out in February, is aimed at children and parents dealing with a cancer diagnosis.

It’s been a long journey for the two friends, much of it uphill.

Lober, of Kansas City, North, had late-stage breast cancer that metastasized to her liver. She still takes regular chemotherapy treatments, but there’s been no sign of cancer for more than 10 years.

Myer, a former surgical nurse who now lives in Overland Park, has been undergoing difficult treatment for hepatitis C, but she, too, has been free of symptoms for about 10 years.

The illustrator, Angie Prindle of Lee’s Summit, also could relate to the topic. Her mother, Barbara Brewer, is a cancer survivor.

The book is part celebration, part mission. Lober hopes the comforting cadence of the poem and the storybook imagery will speak to children and family members affected by cancer.

Originally, Lober said, the women had hoped to donate the proceeds to Touched by Cancer, but that organization has dissolved. Now Lober, a wellness coach, is more interested in using the book as a tool to help parents and children.

If there are profits after she recoups the $2,000 publishing fee, Lober said, the money will be divided among everyone who donated their work to make it happen. She said she’d happily donate her share to charity. The book is available for $16.99 through Amazon and Barnes & Noble and from the authors and illustrator themselves.

Lober and Myer met about 15 years ago through their husbands’ work with the Home Builders’ Association of Greater Kansas City. At the time, they were typical girlfriends who shared common interests and business.

Then, about a year later, Lober suspected something was wrong and began asking doctors to check her for breast cancer.

She had a type of pre-menopausal cancer that was difficult to detect without a biopsy, though, and she says it was two years before she got a cancer diagnosis. By then, the cancer had spread to her liver.

Myer gave her the birthday poem after Lober had undergone her surgeries but before she’d been declared symptom-free. “She was just really hard to buy for,” Myer laughed.

Myer, in the meantime, developed her own health problems. A year after Lober’s cancer was diagnosed, Myer said, she was found to have hepatitis C, which may have been contracted during her earlier years as a surgical nurse.

The two went from being regular girlfriends to “wellness buddies,” just like that, said Lober.

They learned how to eat nutritiously, went to spas and even investigated a Tibetan monk who touted herbal remedies for metastatic breast cancer.

“Having someone who understands what you’re going through helps. It’s priceless,” Lober said. “You know you’re not the lone wolf, going through it all on your own.”

Lober, 48, has self-published two other books, “Love to Live” and “Still Bigger than Pink” about her experiences with cancer. So after she read and re-read the birthday poem, an idea formed.

“It hit me. Oh, my God, this is so good! We need to turn it into a children’s book and have it illustrated.”

Myer immediately took the poem out to a quiet lake dock and started writing.

“When Lori Lober asks you to do something, you usually end up doing it,” she said with a laugh.

“Princess Elle” is an allegorical tale of a little girl on an island. One day she notices things are amiss, and soon she is in the clutches of a powerful dragon called C for carcinoma. However, she makes it through the confrontation and is helped back to wellness by her many bird friends.

“Feathers are important to me,” said Lober. “Whenever I needed hope or a sign, I would find a feather in an unusual place, as if it had been put there by an angel. I think of feathers when I need hope.”

After Myer, 51, and Lober were done tweaking the words, they set out to find an illustrator by sending out emails. Prindle learned about the project through a student’s parent.

By that time, tragedy had struck Lober. Her son, Colby James McLain, 19, died in a car crash in November 2005. After Prindle got the job, she commemorated Colby by working his features into one of the birds in the story. Since publication, Prindle has given away 60 copies and has held a fundraising event at a Lee’s Summit coffee shop.

Prindle, 44, says she had always wanted to illustrate a children’s book, and so was thrilled when her work was chosen. The book is done in watercolor, ink and Photoshop images of a little girl wandering through the island and fighting the dragon. Coincidentally, the girl in the photos is Prindle’s niece, Ellie, who was 5 at the time.

“It’s always everyone’s hope that you have a happy ending, that you conquered it and can move forward with life,” she said. “People can imagine, if this little girl did it, I can do it, too.”

Story books can be useful for children trying to understand cancer, said Amber Masso, national program director for the American Childhood Cancer Organization in Kensington, Md. In fact, one of the group’s functions is to distribute books and materials it’s commissioned for people with cancer. Those include story books.

“Talking about a journey and turning it into a fantasy is definitely more relatable to children,” Masso said. “It’s good to relate it in terms a child can understand, and it’s also a good tool for a parent to have.”

In fact, one of the group’s functions is to distribute books and materials it’s commissioned for people with cancer. Those include some story books, Masso said.

Myer was struggling with a course of treatment, and could not talk long about her book. But she remains upbeat.

“It’s so funny. I got (the book) the day I started treatment,” she says of her most recent round. “So I’ve had to read my own words and walk my own walk.”

Patients May Receive Too Much Acetaminophen in Hospital

30B760C36BB95A2E152E4E447864C6

Use of drugs such as Tylenol, Percocet can exceed recommended daily dose, study finds

-- Mary Elizabeth Dallas

WEDNESDAY, May 23 (HealthDay News) -- Roughly 2.5 percent of admitted hospital patients may receive more than the safe daily cumulative dose of the pain-reliever acetaminophen, best known as Tylenol, on at least one day, according to a new U.S. study.

Patients on more than one drug containing acetaminophen often consume more than the recommended 4 grams per day of the drug, the researchers from Thomas Jefferson University Hospital in Philadelphia found.

Together, two tablets of extra-strength Tylenol contain 1 gram of acetaminophen, commonly used to relieve pain and reduce fever.

Over the course of two years, researchers led by Dr. Jesse Civan examined 46,000 hospital admissions and the medications those patients were given. They found that on at least one day of hospitalization, roughly 1,100 patients received more than 4 grams of acetaminophen in the form of Tylenol, Percocet and similar drugs.

The study authors also assessed the effects the acetaminophen had on the patients' livers and found only a small minority were given a blood test to check their liver function. The investigators noted that this test is typically used only when a doctor has a specific concern about possible problems with a patient's liver.

In the small number of patients who did have the blood test of liver function, the researchers noted that there were no serious liver injuries. They said there wasn't enough information to determine if abnormal test results were the result of excessive exposure to acetaminophen.

Civan and colleagues concluded that more research is needed to determine if new recommendations for the safe daily dosing of acetaminophen are necessary. They added that patients need better education on acetaminophen safety, particularly for use of the drug after they leave the hospital, when patients may try to duplicate the medications and doses they were given during their admission.

The study was presented Monday at the Digestive Disease Week meeting in San Diego. The data and conclusions should be viewed as preliminary until published in a peer-reviewed journal.

Herbal, Dietary Supplements Take Toll on Liver

    

By Cole Petrochko, Associate Staff Writer, MedPage Today

Published: May 22, 2012

Reviewed by Robert Jasmer, MD; Associate Clinical Professor of Medicine, University of California, San Francisco and Dorothy Caputo, MA, BSN, RN, Nurse Planner

SAN DIEGO -- Patients taking herbal and dietary supplements may be at risk for liver injury severe enough to warrant an organ transplant, researchers said here.

In a review of national data, supplements accounted for 18% of liver injuries in the U.S., Jose Serrano, MD, of the National Institutes of Health, reported during a press briefing at Digestive Disease Week.

"The number of cases in our network has increased over the years," Serrano said during the briefing. "There were no deaths, but 7% of patients needed a liver transplant. These are not trivial consequences."

It's estimated that as much as 40% of the U.S. population uses herbal or dietary supplements, but their potential side effects, including hepatotoxicity, are not well defined.

The researchers looked at data from the Drug Induced Liver Injury Network, which evaluated patient information from eight sites across the U.S. from 2003 to 2011.

Of 679 cases of liver injury, 93 were attributed to herbal or dietary supplements, Serrano said, adding that these patients tended to be younger than those who have similar liver injuries due to other medications. The majority of these patients were white.

Among patients that had used supplements, 33% used them for body building, 26% for weight loss, and the remaining 31% used a variety of other types of supplements.

Serrano said the symptoms of liver injury caused by supplements weren't different from those caused by other medications. But one factor that distinguished liver injury from body building supplements over the others was itching, which occurred in 86% of patients.

Those who had liver injury resulting from either body building or weight-loss supplements also tended to have a longer latency time between exposure and injury compared with liver injury from other medications or the miscellaneous category of dietary supplements.

Weight-loss products also appeared to be associated with a more hepatocellular pattern of injury, while body building supplements (usually anabolic steroids) had a more mixed pattern with increments on total bilirubin, Serrano said.

Most of the patients (66%) had to be hospitalized, and 11% developed alterations in liver function that persisted for at least 6 months, he added. The median serum alanine-aminotransferase (ALT) at presentation was 533 U/L, the alkaline phophatase was 166 U/L, and the total bilirubin was 7 mg/dL.

The R-value, which represents liver injury pattern, was in the hepatocellular range (>5%) in 65% of the patients with a median ALT of 1,275 U/L. The range for normal ALT is generally between 7 and 56 units U/L.

Symptoms included:

  • Jaundice (78% of patients)
  • Nausea (60%)
  • Itching (58%)
  • Abdominal pain (47%)

The majority of patients (60%) used only one type of supplement, while 23% used two or more supplements, and 16% used at least one supplement concurrently with prescription drugs.

While the most common injury pattern seen was hepatocellular, the distribution of overall causality scores was not significantly different across injury patterns (P=0.30), the authors stated.

The biggest risk to patients that use supplements is not reporting supplement use to a healthcare professional, noted Donald Jensen, MD, of the University of Chicago and DDW press conference moderator.

"Patients need to be label readers," Jensen told MedPage Today. "They can't just assume that everything out there is safe. There are things out there that can be potentially damaging."

He added that patients think supplements "are food or that they're very safe. And there are some herbal medicines that probably are safe and may even do some benefit for people. I don't want to throw everything in the trash can. But, on the other hand, there are enough [supplements] that are damaging."

He said that future research on supplements should focus on potential patient interactions with herbal supplements, noting that not all patients have negative interactions with them.

"I don't think we're going to stop people from taking herbal medicines," he said. "I'd like to see the FDA regulate the toxic ones better, but otherwise I think the important next step is some scientific understanding of why some people get damaged and others don't."

HCV Patients May Be Able to Delay Therapy

By Kristina Fiore, Staff Writer, MedPage Today

Published: May 22, 2012

Take Posttest

SAN DIEGO -- Hepatitis C patients without significant fibrosis may be able to delay triple therapy and wait for simpler, shorter, and potentially all-oral regimens that are currently under investigation, researchers said here.

The addition of new protease inhibitors telaprevir (Incivek) and boceprevir (Victrelis) to previous standard therapy of interferon and ribavirin have significantly boosted sustained viral response for many patients, especially for blacks and Latinos, according to Maribel Rodriguez-Torres, MD, of the Fundacion de Investigation in Rio Piedras, Puerto Rico.

But patients with less severe disease may be able to hold off until a handful of newer agents -- offering less complex regimens that potentially cut the symptomatic interferon from the mix -- come to market, possibly within the next two years, Rodriguez-Torres said during a symposium at Digestive Disease Week (DDW) here.

"This is a slowly progressing disease and most of the time we have the time and opportunity to determine what's the best [treatment strategy] for our patients," she said. "Patients without significant fibrosis should wait. Those with more advanced disease should consider therapy today."

Triple Therapy Presents Challenges

Clinicians have cited a number of challenges with triple therapy. Both new agents are only indicated for patients with genotype 1 disease -- though this comprises the majority of patients -- and they add a significant cost to treatment, Rodriguez-Torres said.

The regimen is also complex and long-lasting, with both new agents adding multiple daily pills to ribavirin's four to six pills per day and weekly interferon injections, extending for 24 to 48 weeks.

There's also an increased risk of drug-drug interactions, as both new agents inhibit the common CYP34A metabolic pathway, potentially increasing levels of other drugs metabolized that way. That list includes some statins and ACE inhibitors, which "aren't unusual drugs," Rodriguez-Torres said.

Side effects include anemia, a concern because ribavirin already lowers blood hemoglobin levels, she said. Also, telaprevir appears to cause rash in more than 50% of patients.

Instead, a "dream regimen" is a simple one with fewer pills, contains only oral agents, spans all genotypes, and is highly effective with an excellent safety and tolerability profile -- though that possibility is not that far from reality, Rodriguez-Torres said.

Improvements Are on the Horizon

"We've never had such an explosion of drug development in the last 75 years compared to what we see now in chronic hepatitis C," she said. That robust pipeline includes not only a number of protease inhibitors and NS5A inhibitors -- which are typically genotype-specific -- but also nucleoside and cyclophilin inhibitors that are pan-genotypic.

Such robustness may help keep prices down as a result of increased competition, Rodriguez-Torres said. Also, the majority of drugs in development are dosed once or twice daily and some have a much shorter duration of therapy than the current standard of 24 to 48 weeks.

Early data also have shown that it's possible to drop interferon from the regimen. Last month at the European Association for the Study of the Liver meeting Barcelona, researchers reported that high proportions of patients has sustained virologic response rates with an all-oral regimen of ribavirin plus two investigational agents, ABT-450/r, a protease inhibitor, and ABT-072, a non-nucleoside NS5B polymerase inhibitor.

Also at that meeting, an early trial showed that a combination of daclatasvir, an NS5B inhibitor, plus GS-7977, a nucleotide NS5B inhibitor, led to rapid and sustained viral response in patients with genotypes 1-3, with or without ribavirin.

Treatment Issues Remain Complex

The pressing question facing clinicians, then, has been determining who to treat and when. Rodriguez-Torres said the simple answer is to treat those with severe fibrosis now, but hold off on treating those without significant fibrosis.

But Andrew Muir, MD, clinical director of hepatology at Duke University, told MedPage Today the decision should rest largely with the patient.

"I get concerned about us being too heavy handed deciding which patients should or should not get hepatitis C treatment," he said. "Our role should be to guide patients about potential options, and those discussions can take quite a bit of time."

He noted, however, that the side effects "will be much better for these patients with future therapies. But I have had patients elect to proceed with treatment even with early-stage disease. Some have felt it was the right time for them to proceed with treatment for a number of personal reasons. Some worried if they would have stable health insurance in the future."

On the other hand, Zobair Younossi, MD, of Inova Health System in Great Falls, Va., said some of his patients actually "warehouse themselves for regimens that do not include interferon."

Muir also noted that even some advanced fibrosis patients may be eligible for watchful waiting, since not all of them will progress quickly.

"If the patient has great risks to treatment, or if the patient does not think the chance of response is good enough to take on the side effects, then delaying therapy is the right thing for that individual [advanced fibrosis] patient as well," he told MedPage Today. "If they do not take treatment, they must get aggressive about liver wellness. That means no alcohol, get in shape and lose weight if needed, and get tight control of your blood sugars if you have diabetes."

Rodriguez-Torres reported relationships with Abbott Laboratories, Anadys, Bristol-Myers Squibb, Glaxo-SKB, Idera, Intarcia, Merck, Novartis, Pfizer, Pharmasset, Roche, Sanofi-Aventis, Valeant, Vertex Pharmaceuticals, ViroChem Pharma Inc, and Wyeth.

The other researchers reported no conflicts of interest.

U.S. Liver Transplants Declining

DS13110CMA_liver_transplant8

Last Updated: May 22, 2012.

Some livers available for transplant are discarded because they're not healthy enough, study finds.

TUESDAY, May 22 (HealthDay News) -- The number of liver transplants in the United States has decreased since 2006, a new study finds.

Researchers said one reason for the decline is that harvesting livers after cardiac death has become more commonplace, and many of those livers end up being discarded after doctors determine the organs aren't healthy enough to attempt a transplant. Another reason livers are discarded is because of damage due to a condition known as fatty liver disease, which is associated with metabolic syndrome and high cholesterol.

Researchers analyzed data from the United Network for Organ Sharing to assess factors that prompted doctors to discard a donated liver.

With standard donation, a patient is declared brain dead and kept on cardiovascular support so the organs continue to receive oxygen and blood until they are removed for transplant.

In recent years, there has been increasing use of donor organs after cardiac death. In these cases, organs are harvested for transplant after a patient dies and the heart stops on its own. This type of organ donation is promoted as a way to increase the total number of organs available for transplant, and now accounts for 12 percent of organ donations, compared with fewer than 2 percent less than 10 years ago.

Doctors are becoming increasingly reluctant to use organs donated after cardiac death, however, according to the study, which is scheduled to be presented Tuesday at the Digestive Disease Week meeting in San Diego.

The researchers found that the total number of donors who have at least one organ recovered for transplant has stopped increasing over the past few years, despite an increasing proportion of organs donated after cardiac death.

"Cardiac death donation is negatively impacting the overall number of liver transplants that we can do," study leader Dr. Eric Orman, a gastroenterology fellow at the University of North Carolina in Chapel Hill, said in a meeting news release.

He and his colleagues also found that donor characteristics associated with a condition called fatty liver -- including diabetes, obesity, old age and high blood pressure -- all were associated with discarding a donated liver.

Because this study was presented at a medical meeting, the data and conclusions should be viewed as preliminary until published in a peer-reviewed journal.

Hepatitis C Causing Liver Damage in Greater Numbers: Study

Gallbladder-Liver-Pancreas-Location

Last Updated: May 22, 2012.

An additional 300,000 Americans could develop advanced liver disease from the virus by 2015.

TUESDAY, May 22 (HealthDay News) -- Hundreds of thousands of Americans infected with chronic hepatitis C virus could develop potentially life-threatening liver complications over the next few years, according to a new study.

Researchers evaluated medical insurance claims data and found that more than 200,000 hepatitis C patients had advanced liver disease in 2008, and estimated that another 300,000 patients could have advanced liver disease by 2015.

The risk of developing advanced liver disease is especially high among baby boomers, who account for 82 percent of hepatitis C patients in the United States, according to the findings, which are scheduled to be presented Tuesday at the Digestive Disease Week meeting in San Diego.

The study was funded by Vertex Pharmaceuticals, makers of the hepatitis C drug Incivek (telaprevir).

"This alarming finding places additional stress on an already overburdened health care system, which will need to prepare for an increase in patients suffering from advanced liver disease," Ann Kwong, vice president and hepatitis C virus franchise lead at Vertex, said in a meeting news release. "It is critical to treat [hepatitis C] patients before they develop costly and irreversible liver complications."

Screening patients for hepatitis C infection can help doctors identify and potentially cure infection before liver complications occur. Available hepatitis C treatments are most effective in patients without advanced liver disease, so early diagnosis offers patients the best chance to be cured, Kwong said.

Up to 5 million U.S. adults have chronic hepatitis C, and as many as 75 percent of them don't know they have the infection. Chronic hepatitis C is the leading cause of liver cancer and the most common reason for liver transplant in the United States.

Last week the U.S. Centers for Disease Control and Prevention recommended that all Americans born between 1945 and 1965 -- the baby boom generation -- be tested for hepatitis C.

Because this study was presented at a medical meeting, the data and conclusions should be viewed as preliminary until published in a peer-reviewed journal.

Health outcomes explored at DDW® 2012

SAN DIEGO, CA (May 22, 2012) — New research being presented at Digestive Disease Week® (DDW) offers key insights into the progression of diseases leading to liver damage, which affect diverse populations, including young people. Studies show that the increasing rates of obesity are putting teens at risk for developing nonalcoholic fatty liver disease and are decreasing the availability of healthy livers for organ donations, which are urgently needed as people continue to experience complications from diseases, such as hepatitis C and drug-induced liver toxicity.

"Liver disease often leads to lifelong problems and serious consequences," said Donald M. Jensen, MD, professor of medicine, and director, Center for Liver Diseases, University of Chicago Medical Center, IL. "With increasing incidence, it is more important than ever to investigate the causes, prevention and treatment for conditions like nonalcoholic fatty liver diseases and chronic hepatitis C, as well as to identify obstacles to liver transplantation." DDW is the largest international gathering of physicians and researchers in the field of gastroenterology, hepatology, endoscopy and gastrointestinal surgery.

Prevalence of Suspected NAFLD Is Increasing Among U.S. Adolescents (Abstract #705)

Suspected non-alcoholic fatty liver disease (NAFLD) is increasing in teens, affecting approximately 10 percent of the age group, leading to a host of conditions, including liver damage, diabetes, hypertension and cancer. While the common perception has been that there are an increasing number of children identified with NAFLD, previous studies have not demonstrated the rate of that increase nor whether the increase actually exists. Investigators led by Miriam Vos, MD, assistant professor of pediatrics at Emory University and Children's Healthcare of Atlanta, GA, sought to determine whether rates seem high because people are studying them more closely or whether there really are more cases of teenagers with NAFLD.

Investigators determined that the increase in NAFLD was not defined by the number of overweight children. When comparing the rate of increase in children with fatty liver disease to the rate of increase in overweight children, research showed that the increase in children with fatty liver was much greater than the increase in overweight children. This finding demonstrates that just having overweight kids does not explain the increase in fatty liver. Investigators also looked at cross-sectional data to explain the increase and found a link to increased NAFLD and waist circumference (the measure of the distance around the abdomen half way between the inferior margin in the last rib and the crest of the hip bone).

"We know that if a child is overweight, they are more likely to be overweight as an adult, and we know from national data that teens with fatty liver disease become adults with fatty liver disease, unless they improve their diet and lose a significant amount of weight," said Dr. Vos. She added that adolescents may have an easier time losing weight compared to adults because they have been overweight for a shorter period of time.

To increase the likelihood of weight loss success, Dr. Vos supports a multi-sector approach, including community programs and school programs that steadily support healthy food and exercise. These types of programs are increasing around the country, but need to be uniformly available so that entire communities and children are not excluded from their benefits. She also recommends instituting these supportive programs while children are young so that their parents can help them develop good habits at an early age. Dr. Vos added that she is hopeful that, in the future, we will have medications for the most severe cases of NAFLD to help complement a healthy regimen. This summer, the National Institutes of Health (NIH)-sponsored NASH Clinical Research Network will start a new clinical trial to research the treatment of fatty liver.

Dr. Vos and colleagues are also studying the connection between diet and fat in the liver and increased cardiovascular risk. Data show that cardiovascular disease is very high in adults with NAFLD, and multiple studies have shown that adolescents with NAFLD have markers that show increased risk for cardiovascular disease.

In this study, investigators reviewed nationally representative data of more than 10,000 12- to 18-year-olds from the National Health and Examination Survey datasets, spanning from 1988 to 2008, excluding subjects with missing data and known liver disease. Suspected NAFLD was defined as overweight/obese (those with a body mass index greater than the 85th percentile) with elevated alanine aminotransferase (ALT) levels greater than 25.8 for boys or 22.1 for girls, and also as overweight/obese with ALT levels greater than 30 to allow for comparison with previous studies. ALT is a blood test that is typically used to detect liver injury.

Funding for this study was provided by the NIH.

Dr. Vos will present these data on Monday, May 21 at 11:15 a.m. PT in Room 2 of the San Diego Convention Center.

Current and Future Disease Progression of HCV-Infected Patients Among Different Age Cohorts (Abstract# Sa1084)

Several hundred thousand Americans with chronic hepatitis C virus infection (HCV) are predicted to develop potentially life-threatening liver complications within the next few years, according to a new study from Vertex Pharmaceuticals. Risk was found to be dramatically higher among baby boomers, a segment of the population that accounts for 82 percent of all Americans with HCV.

To assess the future health needs of HCV patients, researchers evaluated medical insurance claims data to determine how many individuals with HCV already have advanced liver disease and how many more will develop complications in time. Researchers found that more than 200,000 HCV patients were suffering from advanced liver disease in 2008 and a projected 300,000 additional patients — mostly baby boomers — are on track to develop advanced liver disease by 2015. Without treatment, the number of patients with advanced liver disease is expected to triple by 2015.

"This alarming finding places additional stress on an already overburdened health-care system, which will need to prepare for an increase in patients suffering from advanced liver disease," said Ann Kwong, PhD, vice president and HCV franchise lead at Vertex. "It is critical to treat HCV patients before they develop costly and irreversible liver complications."

Dr. Kwong recommends that one important course of action is a focus on HCV diagnoses. By screening patients for HCV infection, there is a greater opportunity to identify and potentially cure infection before liver complications occur. Currently approved HCV therapies are most effective in patients without advanced liver disease, so diagnosing the virus earlier offers patients the best chance to be cured.

Researchers stressed that not all patients developing liver complications can be accurately identified with insurance claims data. Individuals with existing liver disease may not be diagnosed and therefore cannot be accounted for in this study. In the future, universal screenings for HCV infection are expected to help diagnose not only more cases of HCV, but also lead to more testing for liver complications.

Up to five million U.S. adults have HCV, and 75 percent of them are unaware of their infection. HCV is commonly called a "silent killer" because it often has no symptoms and can go decades without being detected. Chronic HCV is the leading cause of liver cancer and the most common reason for liver transplantation in the U.S.

This study was funded by Vertex Pharmaceuticals.

Dr. Kwong will present these data on Saturday, May 19 at noon PT in Halls C-G of the San Diego Convention Center.

The Number of Grafts Available for Liver Transplantation is Decreasing as a Result of Increasing Donor Age, Metabolic Syndrome and Donation After Cardiac Death (Abstract #841)

The number of liver transplants has declined in the U.S. since 2006, so investigators led by Eric S. Orman, MD, gastroenterology fellow, the University of North Carolina, Chapel Hill, looked at various donor factors to determine why. By studying the United Network for Organ Sharing (UNOS) database for all donor information, researchers assessed which factors prompted physicians to discard an organ.

With standard donation, a patient is declared brain dead and kept on cardiovascular support so the organs can continue to receive oxygen and blood before being removed for transplant. In recent years, surgeons have also increasingly used the method known as donation after cardiac death, which occurs when patients die and the heart stops on its own. Cardiac death donation is considered an alternative way to donate organs and has been promoted as a way to increase the total number of organ donors. An increasingly large percentage of organ donors are in the donation after cardiac death category; less than 10 years ago, it was fewer than 2 percent, but currently, the rate has increased to more than 12 percent.

However, there is a widespread pattern of health-care professionals becoming increasingly reluctant to use organs donated after cardiac death. In reviewing the UNOS database, researchers found that the total number of donors who have at least one organ recovered for transplant has stopped increasing over the past few years, despite an increasing proportion of donation after cardiac death donors.

Investigators looked at the group of organ donors who had at least one organ recovered for transplant to determine whether the donor liver was a fatty liver. By reviewing donor characteristics that are strongly associated with having a fatty liver, such as diabetes, obesity, older age and high blood pressure, researchers found that these factors were all associated with discarding a liver. "Cardiac death donation is negatively impacting the overall number of liver transplants that we can do," said Dr. Orman.

The next step of the research is to look more closely at why more livers are being discarded, how large of a role donation after cardiac death is playing in those organs discarded, and what is driving the increase in donation after cardiac death.

No pharmaceutical funding was provided for this study.

Dr. Orman will present these data on Monday, May 21 at 4 p.m. PT in Halls C-G of the San Diego Convention Center.

Patterns of Usage of Acetaminophen in Excess of Four Grams Daily in a Hospitalized Population at a Tertiary Care Center (Abstract #743)

Hospitalized patients who receive multiple orders of medication containing acetaminophen are likely to receive a higher than intended dose of the drug, even when provided by physicians, according to new research from Thomas Jefferson University Hospital, Philadelphia, PA.

Reviewing 46,000 hospital admissions over a two-year period, investigators led by Jesse Civan, MD, GI fellow, division of gastroenterology, Thomas Jefferson University Hospital, found that about 1,100 individuals received more than 4 grams of acetaminophen on at least one day. In other words, about 2.5 percent of all patients admitted to the hospital received more than what is currently considered the safe cumulative daily dose on at least one calendar day.

Investigators sought to determine exactly how much acetaminophen was being dispensed in a large tertiary-care hospital and how it compared to the generally accepted safe maximum dose. They reviewed a computer database tracking every patient admitted to their hospital and every dose of medicine prescribed and received. This allowed them to calculate exactly how much medication patients were exposed to, including any medication containing acetaminophen, such as Tylenol®, Percocet® and other similar medicines, and to generate a list of all patients who received more than 4 grams of acetaminophen on at least one calendar day.

Researchers also reviewed liver function and injury, which are reported in the same database, to determine potential detrimental effects of acetaminophen use on patients. By reviewing a specific blood test — the alanine amino-transferase (ALT) test, which is generally used to screen for liver injury possibly related to acetaminophen — Dr. Civan and his colleagues found that only a small minority of patients were administered an ALT test. They attribute this finding to the fact that the blood test is only usually checked when a physician is particularly concerned about a possible liver problem.

In the small minority of patients who did have an ALT checked, there was insufficient data to do a "formal cause analysis" to determine whether an abnormal ALT could be blamed on the acetaminophen exposure. Because of the paucity of ALT monitoring, no conclusion could be reached about whether the acetaminophen exposure might have had any detectable detrimental consequences.

Dr. Civan added that these findings could have implications on public health and the need to improve patient education regarding safe dosages at home, since many patients will likely attempt to emulate the medications provided at the hospital once they get home. He concluded that further study in this closely monitored population in which every dose of acetaminophen-containing medication administered is recorded might shed light on the ongoing discussion at the U.S. Food and Drug Administration and elsewhere regarding new recommendations for maximum safe daily dosing. Dr Civan stressed that although it remains unclear whether blood test abnormalities may have resulted from acetaminophen use, he did not find any evidence of any cases of serious liver injury.

Acetaminophen has been under increasing scrutiny in the U.S. — it is the leading cause of acute liver failure and emergent liver transplant, and previous studies have suggested that unintentional overdose is a significant problem. There has also been debate in the medical literature about whether a less severe form of acetaminophen-induced liver injury due to unintentional overdose may be important.

This study received no pharmaceutical funding.

Dr. Civan will present these data on Monday, May 21 at 2:15 p.m. in 6e, San Diego Convention Center.

Herbal and Dietary Supplement Hepatoxicity in the U.S.A. (Abstract #167)

Dietary supplements used for body building and weight loss are the most common of any supplements to cause liver injury, according to new research from the U.S. Drug Induced Liver Injury Network (DILIN). Dietary supplements include herbal remedies, bodybuilding supplements, health food supplements, or anything that people can buy over the counter or online that is not prescribed by a physician.

Liver injury from medication is the main reason why drugs are taken off the market. While estimates suggest that herbal/dietary supplement products are used by up to 40 percent of the U.S. population, their side effects, including potential toxicity, is not well defined. Researchers led by Victor J. Navarro, MD, an investigator funded by the National Institutes of Health-sponsored DILIN, and professor of medicine, pharmacology and experimental therapeutics, Thomas Jefferson University, Philadelphia, PA, sought to explore liver injury from herbal/dietary supplements by examining the types of products taken, and the severity and outcomes associated with liver injury due to them.

Investigators looked at 109 cases of patients in the DILIN who appeared to have liver damage due to dietary supplements; most were male, white and overweight. They found that the supplements most likely to be the cause of liver injury were those reported for body building and for weight loss.

"There is so little regulation of the many products on the market; we couldn't possibly begin to figure out which products to target first without doing this research," said Dr. Navarro. He added that now that they know that bodybuilding and weight loss supplements are the most common causes of dietary supplement-induced injury among the products, they can focus their efforts accordingly.

Investigators are also looking at targeted components of herbal/dietary supplements. For example, previous studies have shown that green tea extract, which can be added to herbal/dietary supplements in high concentrations in pill form, can potentially cause damage to the liver. So DILIN investigators have also sought to determine how common the ingredients of green tea are in dietary supplements when the manufacturer has not identified it as such.

They hypothesized that green tea extract is prevalent in many products but is not specifically identified — in fact, their research has shown that it is present in up to 40 percent of products in which it was not listed on the label. For this reason, investigators will always have difficulty linking liver injuries to green tea extract unless they do a careful analysis of each product.

Dr. Navarro cautioned that because it is not well known how common liver injury is due to dietary supplements, it is difficult to suggest how likely it is that someone would suffer liver damage, but that this is another area where investigators are looking to do more research.

Investigators now have many more cases to study and their next step is to understand how the supplements cause injury and why. They are working with the Food and Drug Administration to identify various contaminants and determine which of the products on the market are the most harmful, especially since herbal/dietary supplement are not tightly regulated. They are also studying possible factors that may predispose a consumer of herbal/dietary supplement to liver injury, such as genetic makeup.

Dr. Navarro will present the DILIN's research data on Saturday, May 19 at 2:15 p.m. PT in Halls C-G of the San Diego Convention Center.

HIV Vaccine Trials Network Opens Enrollment for Phase 1 Trial of GeoVax Labs' Second Generation HIV Vaccine

PR-Logo-Newswire

PRESS RELEASE

May 22, 2012, 8:00 a.m. EDT

Total of 48 Subjects To Be Enrolled at Four Sites Across U.S.

ATLANTA, May 22, 2012 /PRNewswire via COMTEX/ -- GeoVax Labs, Inc. (otcqb/otcbb:GOVX), an Atlanta-based biopharmaceutical firm developing vaccines to prevent and fight Human Immunodeficiency Virus (HIV) infections, today announced that the NIH-funded HIV Vaccine Trials Network (HVTN) has opened enrollment for a Phase 1 trial for the company's second-generation HIV vaccine. The second-generation vaccine is identical to the first generation (currently in a Phase 2a clinical trial) except for the inclusion of granulocyte-macrophage colony-stimulating factor (GM-CSF) as an adjuvant (additive) to enhance vaccine responses. GM-CSF is a normal human protein that promotes the initiation of immune responses. GeoVax's second-generation vaccine co-expresses GM-CSF with HIV proteins in the DNA priming vaccinations. GM-CSF is not included in the MVA boost for the GeoVax DNA prime-MVA boost regimen.

The trial, designated HVTN 094, employs a dose-escalation to evaluate the safety and immunogenicity of the GM-CSF adjuvanted vaccine. In the non-human primate model, co-expression of GM-CSF in the DNA prime achieved a 90% per exposure reduction in infection, a significant improvement over the unadjuvanated vaccine. This difference in vaccine efficacy translated into 70% of vaccinated animals being protected against 12 repeated rectal challenges. Assuming a successful outcome, the company expects the adjuvanted version of the vaccine to be carried forward into Phase 2a/2b efficacy testing.

The HVTN 094 trial will enroll a total of 40 vaccinated and 8 control/placebo subjects to be studied at four sites nationwide: the University of Alabama at Birmingham; Brigham and Women's Hospital, Boston; the University of Rochester, and the San Francisco Department of Public Health. The first inoculation was given at Brigham and Women's Hospital, Boston. Funding for HVTN's conduct of the trial will come from the National Institute of Allergy and Infectious Diseases (NIAID), part of the U.S. National Institutes of Health (NIH).

Robert McNally, Ph.D, President and Chief Executive Officer of GeoVax, said, "We are extremely pleased the HVTN is conducting the trial with the adjuvanted vaccine. They have substantial experience with our unadjuvanted vaccine and possess appropriate expertise for this first human trial of our GM-CSF co-expressing vaccine that has shown such good promise in preclinical studies."

About GeoVax GeoVax Labs, Inc. is a biotechnology company developing human vaccines for HIV (Human Immunodeficiency Virus - that leads to AIDS). GeoVax's HIV/AIDS vaccine technology is exclusively licensed from Emory University in Atlanta, GA, and is the subject of more than 20 issued or filed patent applications. GeoVax vaccines are designed for use in uninfected people to prevent acquisition of HIV-1 and limit the progression to AIDS should a person become infected. GeoVax vaccines are also being tested as a therapeutic treatment (for people already infected with the HIV-1 virus).

GeoVax's core vaccine technologies were developed by Dr. Harriet Robinson, Chief Scientific Officer, through a collaboration of colleagues at Emory University's Vaccine Center, the National Institute of Allergy and Infectious Diseases (NIAID), the Centers for Disease Control and Prevention (CDC) and GeoVax. The technology uses recombinant DNA to prime the immune response and recombinant modified vaccinia Ankara (MVA) to boost the primed response. Both the DNA vaccine and the MVA vaccine express non-infectious virus-like-particles displaying the natural trimeric form of the HIV envelope protein.

GeoVax's vaccines have moved forward in human clinical trials conducted by the HIV Vaccine Trials Network (HVTN) based in Seattle, Washington. These trials have tested various combinations and doses of the DNA and MVA vaccines, their ability to raise anti-HIV humoral (antibody) and cellular (cytotoxic T cell) immune responses, as well as, the vaccines' safety. Successful results from Phase 1 testing supported Phase 2 testing in an ongoing, fully enrolled, 299 participant trial in North and South America. The vaccine is also undergoing Phase 1 /2 testing as a therapeutic in HIV-infected individuals.

About the HVTN The HVTN is the largest worldwide clinical trials network dedicated to the development and testing of preventive HIV/AIDS vaccines. The HVTN is an international collaboration that conducts all phases of clinical trials, from evaluating experimental vaccines for safety and the ability to stimulate immune responses, to testing vaccine efficacy. Support for the HVTN comes from the National Institute of Allergy and Infectious Diseases (NIAID), part of the U.S. National Institutes of Health (NIH). The Network's HIV Vaccine Trial Units are located at leading research institutions in 27 cities on four continents. The Network's headquarters are at the Fred Hutchinson Cancer Research Center in Seattle, Washington.

About NIAID NIAID conducts and supports research--at NIH, throughout the United States and worldwide--to study the causes of infections and immune-mediated diseases, and to develop better means of preventing, diagnosing, and treating these illnesses. News releases, fact sheets and other NIAID-related materials are available on the NIAID Web site at http://www.niaid.nih.gov/ .
