[Helper cells, viral load, genetic factors, co-infections. Prognostic factors in HIV-1 infection].
The ideal time to initiate antiretroviral therapy in asymptomatic patients with chronic HIV infection remains to be defined. The most relevant laboratory parameter is the CD4 cell count. Therapy should be started before the CD4 cells drop below 200/microliter and the immune system becomes compromised. In contrast to past recommendations, viral load should not be used as a single laboratory parameter for initiation of antiretroviral therapy in asymptomatic untreated patients. The determination of genetic factors to assess the prognosis of HIV patients has not yet been incorporated into daily clinical practice. While co-infection with GBV-C is a prognostically favorable factor for the course of the HIV infection, replicative hepatitis C is associated with increased mortality.
