[Current clinical aspects of HIV/AIDS].

OF NEW CLINICAL DEMONSTRATIONS: Since the use of HAART, morbidity and mortality in HIV-infected patients have decreased dramatically. But increased survival in these patients is associated with other diseases (malignant diseases, inflammatory reactions after initiation of HAART) and with drug toxicity (lipodystrophy, mitochondrial toxicity). TRANSMISSION AND REVELATION: Despite widespread information on HIV, new HIV-infected patients with an AIDS-defining illness are still detected. At present, heterosexuality is the most frequent risk factor for HIV-infection (51%). Pneumocystis pneumonia remains the most common opportunistic illness in HIV-infected patients (28%).
