Early virologic responses increases levels of adherence to Hep C therapy
This month's issue of the Annals of Internal Medicine examines the relationship between adherence to Hepatitis C virus therapy and virologic outcomes.
Adherence to therapy with pegylated interferon and ribavirin for hepatitis C virus (HCV) infection has been incompletely examined.
Dr Vincent Lo Re and colleagues from Pennsylvania, USA evaluated the relationship between adherence to HCV therapy and early and sustained virologic response, assess changes in adherence over time, and examine risk factors for nonadherence.
The team performed a retrospective cohort study of the National Veterans Affairs Hepatitis C Clinical Case Registry.
Early virologic response increased with higher levels of adherence to ribavirin
Annals of Internal Medicine
The team assessed 5706 HCV-infected patients with at least 1 prescription for both pegylated interferon and ribavirin between 2003 and 2006 and HCV RNA results before and after treatment initiation.
The research team calculated adherence over 12-week intervals by using pharmacy refill data.
End points included early virologic response and sustained virologic response.
Early virologic response increased with higher levels of adherence to ribavirin therapy over the initial 12 weeks.
Among patients with HCV genotype 1 or 4, sustained response increased with higher adherence to ribavirin therapy over the second, third, and fourth 12-week intervals. Results were similar for adherence to interferon therapy.
The team noted that mean adherence to therapy with interferon and ribavirin decreased by 3.4 and 6.6 percentage points per 12-week interval, respectively.
Patients who received growth factors or thyroid medications during treatment had higher mean adherence to antiviral therapy.
Dr Lo Re and colleagues commented, "Early and sustained virologic responses increased with higher levels of adherence to interferon and ribavirin therapy."
"Adherence to therapy with both antivirals decreased over time, but more so for ribavirin."

Burden of cirrhosis and hepatic encephalopathy on patients and caregivers
The most recent issue of the American Journal of Gastroenterology evaluates multi-dimensional burden of cirrhosis and hepatic encephalopathy on patients and caregivers.
Cirrhosis and hepatic encephalopathy can adversely affect survival, but their effect on socioeconomic and emotional burden on the family is not clear.
Dr Jasmohan Bajaj and colleagues from Virginia, USA studied the emotional and socioeconomic burden of cirrhosis and hepatic encephalopathy on patients and informal caregivers.
A cross-sectional study in 2 transplant centers of cirrhotic patients and their informal caregiver was performed.
Demographics for patient/caregivers, model-for-end-stage liver disease (MELD) score, and cirrhosis complications were recorded.
Patients underwent a cognitive battery, sociodemographic, and financial questionnaires.
Cirrhosis-related expenses impact the family unit's daily functioning
American Journal of Gastroenterology
Caregivers were given the perceived caregiver burden and Zarit Burden Interview (ZBI)-Short Form, and questionnaires for depression, anxiety, and social support.
A total of 104 cirrhotics and their caregivers were included.
Cirrhosis severely impacted the family unit with respect to work, finances, and adherence.
Those with previous hepatic encephalopathy had worse unemployment and financial status, and posed a higher caregiver burden.
The research team observed that cognitive performance and MELD score were significantly correlated with employment and caregiver burden.
Veterans and non-veterans were equally affected.
On regression, depression score, MELD, and cognitive tests predicted both PCB and Zarit Burden Interview score.
Dr Bajaj's team comments, "Previous hepatic encephalopathy and cognitive dysfunction are associated with worse employment, financial status, and caregiver burden."
"Cirrhosis-related expenses impact the family unit's daily functioning and medical adherence."
"A multidisciplinary approach to address this burden is required."

CDC Moves to Make Organ Transplantation Safer
Proposed guideline would screen more aggressively for hepatitis B and C
WEDNESDAY, Sept. 21 HealthDay.-- More thorough donor screening and more advanced organ testing to help protect transplant patients from infectious diseases are recommended in a draft of an updated organ transplant guideline released Wednesday by the U.S. Centers for Disease Control and Prevention.
The goal of the new guideline is to reduce infections such as HIV (the virus that causes AIDS), hepatitis B virus (HBV), and hepatitis C virus (HCV). Screening is already done for HIV, but HBV and HCV should be added to the screening process, the CDC said.
From 2007 to 2010, the CDC was involved in more than 200 investigations of suspected, unexpected transmission of HIV, hepatitis B and hepatitis C through transplants. In some of the confirmed cases, the transplant recipient died due to the infection.
The existing guideline was created in 1994. Other major proposed changes to the guideline include updated and more sensitive tests for donor organs, and a revised set of donor risk factors that can help doctors get a better idea of possible problems with donors' organs.
The new draft guideline focuses on organ safety because the U.S. Food and Drug Administration has already implemented tighter regulations for tissue and semen donors.
"Our first priority must be patient safety. These recommendations will save lives and reduce unintended disease in organ recipients," Dr. Matthew J. Kuehnert, director of the CDC's Office of Blood, Organ and Other Tissue Safety Office, said in a CDC news release. "The guideline will help patients and their doctors have information they need to fully weigh risks and benefits of transplanting a particular organ."
The Draft 2011 Public Health Service Guideline for Reducing Transmission of HIV, HBV, and HCV through Solid Organ Transplantation can be found at www.regulations.gov. The review-and-comment period will last 60 days.

Complementary and Alternative Medicine
Source: Thomas Jefferson University
Newswise — (PHILADELPHIA) – Mood disorders are among the most prevalent mental health issues today. While medication is available, more and more people are turning to complementary and alternative medicine (CAM), including herbal remedies, acupuncture, and meditation to help manage their mood disorders.
Mood and anxiety disorders include a broad range of diagnoses such as major depression; dysthymia, a type of mild depression, and others.
A 2007 National Health Interview Survey (NHIS) showed that almost 40 percent of adults use CAM, with Americans with depression more likely to use CAM remedies than conventional antidepressants or psychotherapy.
Newberg, Monti and Moss evaluated CAM modalities across four categories: natural products; mind-body medicine and manipulative and body-based practices; and other CAM practices. A snapshot of their findings is outlined here:
Natural Products
Botanical medicines, vitamins, minerals and natural products found to positively impact patients with mood disorders, include: Hypericum (St. John’s Wort); S-adenosyl-methionine- an amino acid essential in production and delivery of dopamine, serotonin and norepenephrine throughout the brain; Omega-3 fatty acids- essential fatty acids (EFAs) play a role in maintaining brain structure and function. Research shows that reduced levels of EFAs may be associated with depression. The most common source of EFAs is fish oil.
Mind-body practices
Meditation, yoga, qi-gong, tai-chi and acupuncture are among the most commonly used.
Yoga is effective in improving anxiety and depression, suggests a growing body of research; Meditation-based practices such as mindfulness-based stress reduction and mindfulness-based cognitive therapy have supporting data suggesting therapeutic benefit, including decreases in depression, anxiety and distress for a variety of health conditions, including mood disorders; Acupuncture- inconclusive evidence shows acupuncture can be a beneficial treatment modality for mood disorders.
Other CAM products
There are several CAM products that are used for mood disorders, but many have little supporting data. A few that do include: TRP and 5-HTP, amino acid precursors of serotonin, and the botanical Rhodiola rosea.
The popularity of CAM interventions within the general Western population continues to grow as does the body of rigorous research into the effects and mechanisms of CAM interventions for mood disorders.
“As the field grows, we anticipate that the data will be able to provide a more detailed evaluation of CAM interventions with more practical applications regarding potential benefit effects and helping to avoid adverse effects,” conclude Drs. Newberg and Monti and Moss.

FDA Confirms Source of Listeriosis
By Cole Petrochko, Associate Staff Writer, MedPage Today
The agency found traces of Listeria monocytogenes in company cantaloupe samples from a store and a packing facility, as well as on equipment at the facility, the FDA said in a statement. The infectious traces match one of the three strains involved in the multi-state outbreak of listeriosis.
Jensen Farms recalled its Rocky Ford brand cantaloupes as a precautionary measure following the outbreak announcement in mid-September. The affected produce was shipped from July 29 to Sept. 10 to at least 17 states, which may have distributed them further, the statement said.
Since that announcement, the number of patients affected by the bug has grown to 35, while the number of deaths has risen to four.
Listeriosis can be fatal to some high-risk patients, such as patients ages 60 and older and those with compromised immune systems, in addition to the offspring of pregnant mothers with the disease.
Listeria bacteria are commonly found in water, soil, some farm animals, raw meat, raw sprouts, raw milk and raw milk products, and some processed meat products. They can survive and grow in the cold of a refrigerator.
The FDA added that customers should throw out any Rocky Ford brand cantaloupe, as bacteria may be on the cantaloupe's skin, and that cutting it may transfer bacteria from the outside to fruit inside.
The agency noted that it is working with Colorado state health officials to determine how the produce became contaminated and to develop potential controls to prevent future outbreaks.
