Interferon combined with ribavirin treatment is effective for children with chronic Hepatitis C virus

Nearly half of 118 children with chronic Hepatitis C virus (HCV) treated with a combination of interferon-alpha-2b and an optimized dose of ribavirin achieved sustained viral response, and side effects were generally mild.

Breastfeeding does not raise the risk of mother-to-child transmission of hepatitis C virus

One study found that infant girls are twice as likely to be infected as infant boys. Both studies provide new information with which to counsel pregnant women infected with HCV. Taken together, the two new studies expand upon preliminary data from smaller studies of mother-to-child transmission of HCV.

Morphine withdrawal enhances hepatitis C virus (HCV) replicon expression

Researchers at the University of Pennsylvania have demonstrated that morphine withdrawal complicates hepatitis C by suppressing IFN-alpha-mediated immunity and enhancing virus replication.

Hepatitis C linked to illegal blood donation in China

Research in a rural province of central China has documented that illegal blood donation practices led to high hepatitis C virus (HCV) infection rates in blood and plasma donors during the 1980s and early 1990s, and that failure to screen for HCV in transfusion recipients increased their risk of infection as well

Infants and adolescents vaccinated against hepatitis B are protected for over 10 years after immunisation

...concludes a study in this week’s issue of The Lancet. The authors state that booster doses of vaccine do not seem necessary to ensure long-term protection.

Third Wave Technologies files patent suits against Chiron and Bayer

The company last Friday filed suit against Digene Corp., seeking a court ruling supporting Third Wave's right to sell its human papilloma virus (HPV) products. Third Wave today also filed suit against Chiron Corp., Bayer Corp., and Bayer HealthCare LLC asking for a similar ruling about its right to sell its hepatitis C virus products.

20 percent of people with chronic hepatitis C who receive a liver transplant will develop advanced cirrhosis

A new study from the University of North Carolina at Chapel Hill School of Medicine may have found a way to identify those at greatest risk, thereby allowing doctors to decide who should receive treatment that could save the transplanted organ. The new findings appear in the October issue of the journal Liver Transplantation.

Research highlights the role of viral sequence analysis in improving our overall understanding of hepatitis A cases in the U.S.

Novel use of genetic testing methods helped public health officials control and limit the further spread of four outbreaks of foodborne hepatitis A virus in 2003 related to the consumption of green onions, according to a detailed analysis published in the October 15 issue of The Journal of Infectious Diseases, now available online.

Drug that blocks acid buildup inside cells revs up the immune response to vaccines

Reporting in the current issue of The Journal of Experimental Medicine, Vincenzo Barnaba and his team at the University of Rome show that people receiving booster shots against hepatitis B virus developed more robust immune responses if given a widely used anti-malaria drug called chloroquine.

Stressgen granted new U.S. patent for treatment of Hepatitis B

Stressgen Biotechnologies announced today that the U.S. Patent and Trademark Office granted Patent Number 6,921,534 covering fusion protein compositions comprised of a hepatitis B virus (HBV) antigen fused to a heat shock protein (Hsp), as well as DNA encoding such fusion proteins, and methods of treating an HBV infection using these fusion proteins.

Designer molecules that combine metals such as copper with natural organic materials could treat diseases in the body

That's the finding of chemists at Ohio State University, who have successfully tested such molecules against portions of HIV and Hepatitis C virus RNA in the laboratory. They've also created molecules that act like ACE, or angiotensin-converting enzyme, inhibitors - drugs that are used to lower blood pressure.

Immunity - another important function of the mitochondria

Researchers have discovered a surprise lurking inside mitochondria, the power plants that are present in every cell. It turns out that these powerhouses also contain a protein that triggers the immune system to attack viral invaders.

Susceptibility to Hepatitis A in patients with chronic liver disease due to Hepatitis C virus infection: missed opportunities for vaccination

A new study examining whether patients with chronic Hepatitis C virus (HCV) were routinely vaccinated against Hepatitis A virus (HAV) found that vaccination rates were low, even though HAV vaccination is recommended for patients with chronic liver disease.

Study examines the incidence and risk factors associated with Hepatitis C infection in rural Egypt

The prevalence of antibodies to Hepatitis C Virus (HCV) in Egypt is among the highest in the world. From the 1950s until 1982 hundreds of thousands were infected during mass campaigns to control schistosomiasis (a parasitic disease) using mass therapy with intravenous antimony compounds, but little is known about current risk factors and rates of transmission.

Molecular link between a viral infection and development of a common and fatal form of liver cancer

Researchers at The University of Texas M. D. Anderson Cancer Center have uncovered a crucial molecular link between a viral infection and development of a common and fatal form of liver cancer. In the process, they have identified a possible way to treat this disease as well as a number of other cancers.

Combination of ribavirin and interferon is more effective in treating hepatitis C than using interferon alone

The researchers reviewed 72 randomized trials and 9,991 patients who had chronic hepatitis C for more than six months and were previously untreated, who had relapsed after treatment or who had not responded to other treatment.

Sirna Therapeutics granted new UK patents

Sirna Therapeutics has announced that the United Kingdom (UK) Patent Office has granted the Company two additional short interfering RNA (siRNA) target patents. The first patent covers any siRNA with one or more chemical modifications targeting Vascular Endothelial Growth Factor (VEGF).
