HIV/AIDS drugs interfere with brain's 'insulation,' Penn-CHOP team shows

In a new study, researchers from the University of Pennsylvania and The Children's Hospital of Philadelphia found that commonly used antiretroviral medications disrupted the function of oligodendrocytes, crucial brain cells that manufacture myelin, the fatty material that serves to insulate neurons, helping them transmit signals in the brain fast and efficiently.

Predictors of HIV-related peripheral neuropathy in the modern era

Researchers at major clinical centres in the U.S. have collaborated to study potential causes of peripheral neuropathy (PN) among HIV-positive people in the modern era. They recruited about 500 people who were free from PN and monitored them for an average of two years, performing extensive assessments. Taking into account many issues, statistical analysis found that there were several factors associated with an increased risk for PN.

HIV can spread early, evolve in patients' brains

HIV can genetically evolve and independently replicate in patients' brains early in the illness process, an analysis of cerebral spinal fluid has found. Prompt diagnosis and treatment with antiretroviral therapy should reduce the risk that the virus could find refuge and cause damage in the brain, where some medications are less effective -- potentially enabling it to re-emerge, even after it is suppressed in the periphery, say researchers.
