Do Drug Therapies Raise Risk Of Bladder Cancer?

Summary:
In a recent study of possible triggers of cancer among northern New England residents, epidemiologists identified an enhanced risk to the bladders of patients taking drugs that suppress the immune system.

In her most recent study of possible triggers of cancer among northern New England residents, Dartmouth epidemiologist Margaret R. Karagas, Ph.D., and her team identified an enhanced risk to the bladders of patients taking drugs that suppress the immune system.

The findings, from a population-based, case-control study in New Hampshire, appear in the September 2009 issue of the British Journal of Cancer, with Dartmouth Medical School student Karl Dietrich as first author, with DMS professors Alan R. Schned, M.D., and John A. Heaney, M.D., as co-authors, and with Karagas, a professor of community and family medicine at DMS, as principal investigator.

The report examines the long-term use of glucocorticoids by 786 bladder-cancer patients and by 1,083 control subjects. Doctors commonly prescribe a combination of cytotoxic drugs and glucocorticoids as immunosuppressive therapy to help recipients of transplants avoid rejection of their new organs, and patients with rheumatoid arthritis, asthma, and other conditions often take glucocorticoids.

Previous research, in some of which Karagas participated, has shown associations between such drug therapies and higher risk of skin cancer and lymphoma.

A similar risk for bladder cancer, the new report says, "might indicate the need for closer monitoring of individuals who regularly take glucocorticoids."

Gilead's $1000-a-Pill Drug Could Cure Hep C in HIV-Positive People

Gilead's $1000-a-Pill Drug Could Cure Hep C in HIV-Positive People

TheStreet (July 21, 2014) New research shows Gilead Science's drug Sovaldi helps in curing hepatitis C in those who suffer from HIV. In a medical study, the combination of Gilead's Hep C drug with anti-viral drug Ribavirin cured 76% of HIV-positive patients suffering from the most common hepatitis C strain. Hepatitis C and related complications have been a top cause of death in HIV-positive patients. Typical medication used to treat the disease, including interferon proteins, tended to react badly with HIV drugs. However, Sovaldi's %1,000-a-pill price tag could limit the number of patients able to access the treatment. TheStreet's Keris Lahiff reports from New York. Video provided by TheStreet
