Old virus, new tricks...

HIV patients are now living longer but with a trade off - they now experience accelerated ageing and dementia...


Some fifteen years into the era of protease inhibitors and drug cocktails, doctors are realizing that the miracles the drugs promised are not necessarily a lasting solution to the disease. Most news accounts today call HIV a chronic, manageable disease. But patients who contracted the virus just a few years back are showing signs of what’s being called premature or accelerated aging. ...Doctors are also reporting a constellation of ailments in middle-aged patients that are more typically seen at geriatric practices, in patients 80 and older. They range from bone loss to organ failure to arthritis.
Making matters worse, HIV patients are registering higher rates of insulin resistance and cholesterol imbalances, and they suffer elevated rates of melanoma and kidney cancers and seven times the rate of other non-HIV-related cancers.
Whether this is a result of the drugs or the disease itself, or some combination, is still an open question and certainly varies from patient to patient and condition to condition. Either way, it is now clear that even patients who respond well to medications by today’s standards are not out of the woods. Current life-expectancy charts show that people on HIV medications could live twenty fewer years on average than the general population.
