Major gaps in hepatitis C care identified as new drugs, screening efforts emerge

Major gaps in hepatitis C care identified as new drugs, screening efforts emerge

A new meta-analysis published online in PLOS ONE by infectious disease and epidemiology specialists from the Perelman School of Medicine at the University of Pennsylvania highlights significant gaps in hepatitis C care that will prove useful as the U.S. health care system continues to see an influx of patients with the disease because of improved screening efforts and new, promising drugs. In the largest study of its kind, the team examined data culled from 10 studies between 2003 and 2013 and found that less than 10 percent of people infected with hepatitis C in the United States — 330,000 of nearly 3.5 million people — were cured (achieved viral suppression) with antiviral hepatitis C treatment Continue reading

Fighting parasitic infection inadvertently unleashes dormant virus

Fighting parasitic infection inadvertently unleashes dormant virus

Signals from the immune system that help repel a common parasite inadvertently can cause a dormant viral infection to become active again, a new study shows. Further research is necessary to understand the clinical significance of the finding, but researchers at Washington University School of Medicine in St. Louis said the study helps illustrate how complex interactions between infectious agents and the immune system have the potential to affect illness.

Invisibility cloak for immune cells keeps system healthy

The human immune system is very complex. A large number of different cells with various functions ensure that invading microorganisms such as viruses or bacteria can quickly be rendered innocuous and the entire organism stays healthy Continue reading

Virus kills triple negative breast cancer cells, tumor cells in mice

Virus kills triple negative breast cancer cells, tumor cells in mice

A virus not known to cause disease kills triple-negative breast cancer cells and killed tumors grown from these cells in mice, according to Penn State College of Medicine researchers. Understanding how the virus kills cancer may lead to new treatments for breast cancer Continue reading

Conditions linked to deadly bird flu revealed: High risk areas identified

A dangerous strain of avian influenza, H7N9, that’s causing severe illness and deaths in China may be inhabiting a small fraction of its potential range and appears at risk of spreading to other suitable areas of India, Bangladesh, Vietnam, Indonesia and the Philippines, according to a new study published today in the journal Nature Communications .

Viral infections, including flu, could be inhibited by naturally occurring protein

Viral infections, including flu, could be inhibited by naturally occurring protein

By boosting a protein that naturally exists in our cells, an international team of researchers led by the University of Pittsburgh Cancer Institute (UPCI), partner with UPMC CancerCenter, has found a potential way to enhance our ability to sense and inhibit viral infections. The laboratory-based discovery, which could lead to more effective treatments for viruses ranging from hepatitis C to the flu, appears in the June 19 issue of the journal Immunity . The research is supported by the National Institutes of Health. Continue reading
