HIV resistance to favored treatment not uncommon

By Andrew M. Seaman (Reuters Health) – Resistance to a key HIV drug is common worldwide and could mean trouble for treating and preventing the virus that causes AIDS, according to a new study. In some parts of the world, more than half of people who continued to have uncontrolled HIV despite treatment turned out to have a form of the virus that is resistant to the drug tenofovir, researchers report in The Lancet Infectious Diseases. The new study suggests treatment and monitoring of HIV patients around the world needs to be improved, and surveillance also needs to be increased, said senior author Dr. Ravi Gupta, of University College London.
