HIV patients build normal immune strength in study

(Reuters) - AIDS drug cocktails may be able to restore the ravaged immune systems of some people infected with HIV, researchers reported on Wednesday.

Immune cells known as CD4 T-cells returned to normal levels in an ideal group of patients, picked because they responded optimally to a combination of at least three AIDS drugs, the researchers reported in the Lancet medical journal.

The human immunodeficiency virus, which causes AIDS, plunders the immune system, leaving people vulnerable to a range of infections that may prove fatal.

AIDS is incurable, but doctors try to prop up the immune system with life-extending drug therapy aimed at reducing the amount of virus in the body.

The study involved 1,835 HIV-infected people drawn from a larger study involving more than 14,000 patients from across Europe, Israel and Argentina.

"I think it's very encouraging that if people can respond to treatment well enough and can suppress the virus for long enough, we have sufficient evidence to say their CD4 counts can return to normal," Dr. Amanda Mocroft of Royal Free and University College Medical School in London, one of the researchers, said in a telephone interview.

"Our previous understanding was that there was a plateau in CD4 counts so that CD4 counts would stop increasing after a sufficiently long time taking combination therapy," she added.
