RESUMEN
HIV-infected women from S o Paulo city were enrolled in a cross-sectional study on Human Papillomavirus (HPV) and cervical intraepithelial neoplasia (CIN) prevalence and their association with laboratory markers of AIDS, namely HIV viral load and CD(4)(+) cell counts. A cervical specimen was collected and submitted to Hybrid Capture, a test for HPV viral load determination. HPV-DNA was detected in 173 of 265 women (64.5). Twenty (7.5) women were infected by one or more low-risk viruses, 89 (33) by one or more high-risk viruses, and 64 (24) harbored at least one HPV type from each risk group. Abnormal smears were observed in 19 of the patients, though there were no invasive carcinomas. Severely immunosuppressed patients (CD(4)/microL <100) were at the greatest risk of having a cytological abnormality and a high high-risk HPV viral load.

A 400mg dose twice-a-day oral acyclovir prophylaxis regimen was evaluated in 50 allogenic transplant recipients. Twenty (40 percent) patients experienced 24 episodes of herpes simplex virus (HSV) shedding; 17 (70.8 percent) occurring during prophylaxis. Thirteen of such episodes were asymptomatic and, in three, it was difficult to differentiate severe mucositis from viral lesions. In the remaining one, HSV pneumonia was suspected after a bronchoalveolar lavage (BAL) procedure performed in an attempt to early detection of cytomegalovirus (CMV). All cases responded to acyclovir therapy or dose adjustment suggesting that acyclovir resistance did not account for the occurrence of infection in our patients. These data demonstrated that oral acyclovir prophylaxis, 400mg dose twice-a-day, was inadequate to suppress viral shedding. The bronchoalveolar lavage procedure in a patient with HSV shedding could precipitate HSV spread to the lungs and the occurrence of pneumonia.
