Twenty years after it was first recognized, the HIV/AIDS epidemic continues to expand, but its impact varies greatly in different parts of the World. The worst of the epidemic is now centered in developing countries, especially sub-Saharan Africa, and areas such as Eastern Europe, which was only marginally involved a few years ago but has recently experienced the largest growth in the epidemic. In industrialized countries Highly Active Antiretroviral Therapy (HAART) has changed the natural history of HIV/AIDS, causing a reduction in mortality and morbidity due to HIV/AIDS and related diseases. Many interlocking factors determine the impact of HAART at the population level, including reduction of morbidity and mortality, changes in the natural history of HIV/AIDS and associated illnesses, and the effects of HAART on HIV transmission. To fully appreciate the potential benefits of HAART, the epidemic should continue to be monitored in the future, and the effects of HAART on reducing HIV transmission should also be evaluated. Interventions addressed to encourage the adoption of safer sex practices are badly needed, since a “rebound” in risky sexual behaviors was recently reported among high risk groups, which is, at least in part, attributable to the optimism about new treatments.

UNLABELLED Our objective was to describe morphologic and metabolic disorders in patients treated with highly active antiretroviral therapy (HAART) since primary HIV infection (PHI). Our method was prospective evaluation of patients with PHI initiating HAART at the time of diagnosis. Outcome measures were: development of hyperglycemia, hypercholesterolemia, hypertriglyceridemia, and of body shape abnormalities indicative of lipodystrophy, assessed through self-reported questionnaires and physical examination. RESULTS From May 1997 to April 2001, 41 patients (35 males) with PHI presented at the National Institute for Infectious Diseases "Lazzaro Spallanzani" in Rome, Italy. A protease inhibitor-including regimen was started in 30 patients, and a nonnucleoside reverse transcriptase-inhibitor in 11. Median interval between enrollment and treatment initiation was 30 days (mean 39, range 10-150). Median HAART duration was 19 months (mean 21.2, range 3-47). Thirty-eight patients had undetectable (less than 80 cp/mL) HIV RNA after a median of 3 months (mean 4.1, range 1-15). Mean CD4 cells count increased from 632/mmc at baseline to 936/mmc at the last follow up. No cases of hyperglycemia (glucose level greater than 110 mg/dL) were observed. After a median of 6 months on HAART, 10 patients developed beyond grade 2 (greater than 240 mg/dL) hypercholesterolemia, 5 developed beyond grade 2 (greater than 400 mg/dL) hypertrygliceridemia, and two developed both. Body mass index did not change significantly. Five patients (12.2%) developed lipodystrophy after a median of 14.5 months (mean 15.3, range 2-30), with an incidence of 7.3 per 100 patient-years. CONCLUSIONS Dyslipidemia and lipodystrophy can occur in patients treated with HAART since PHI. This risk of should be taken into account when considering this early antiretroviral treatment of HIV infection.
