Numerous Factors Affect Success Of Interferon Treatment For Hepatitis C
"A new study on predicting outcomes of standard treatment for hepatitis C virus (HCV) infection found that a number of factors impacted responses, including the form of the interferon given. However, for some genotypes of the disease, few of these factors play a role."

Idenix Study of Hep C Drug Put on Hold
CAMBRIDGE, Mass., July 13 (UPI) - "Idenix Pharmaceuticals said Friday its studies of potential hepatitis C drug valopicitabine have been placed on clinical hold in the United States. Following discussions with the Food and Drug Administration, the hold was placed on the company's development program due to the "overall risk/benefit profile observed to date in clinical testing," Idenix said in a statement issued Friday."

Hep-Outbreak Probers Eye Double Dip Syringes
July 1, 2007 - "Health investigators are looking into whether an anesthesiologist suspected of spreading hepatitis infections tainted batches of medication by "double dipping" syringes into vials used for multiple patients, The Post has learned. In a widening probe, officials are also investigating whether other doctors may have used such sloppy methods - or cut corners on safety to lower costs, sources said."

 

Hepatitis C: An Epidemic Bigger Than HIV
"Conditions such as HIV are known as epidemics worldwide, but Dr. Allen Reuben said there is another disease that's an even bigger problem in the United States. Reuben, a consultant in infectious diseases for the Medical Center of McKinney, said about 2 percent of the population in the United States is infected with Hepatitis C."

 

Patient Alert After Hep C Scare [Australia]
"Thousands of patients of a Sydney doctor are being urged to be tested for blood-borne viruses, including HIV, after three women contracted hepatitis C as a result of poor infection control at the eastern suburbs clinic.

The clinic in upmarket Double Bay was closed and an investigation launched."

 

Music CD To Reduce Hep C Infection [UK]

School Nurses Should Act On Human Bites
WASHINGTON, July 25 - "U.S. school nurses are being urged to take a proactive stance concerning human bites - especially against the risk of hepatitis B and C. Bite victims are usually concerned about HIV transmission, but epidemiological data show the transmission rate for HIV from saliva is insignificant, according to a paper in The Journal of School Nursing."

 

OctoPlus Announces Promising Results for Locteron Phase IIa Clinical Study
LEIDEN, The Netherlands, July 26, 2007- "OctoPlus N.V., the drug delivery and development company, announces today positive initial results of the ongoing SELECT-1 Phase IIa study with its lead product Locteron(TM) , a controlled release interferon alfa for the treatment of chronic hepatitis C (HCV)."
