Abstract

Objective: To determine the frequency of asymptomatic perianal shedding of herpes simplex virus (HSV) in adult patients with acquired immunodeficiency syndrome (AIDS). Design: Cross-sectional study. Setting: A 1000-bed, state-supported hospital in Brazil that provides comprehensive health care. Patients: Eighty-two consecutively hospitalized patients with AIDS (Centers for Disease Control and Prevention class C). Main Outcome Measurement: Specimens for HSV culture were obtained with premoistened swabs of the perianal region at approximately 7-day intervals during the hospitalization of each patient. After the specimens were inoculated into cultures of human foreskin and Vero cells, supernatants of cultures showing the cytopathic effect characteristic of HSV infection were tested for virus in a confirmatory immunoenzymatic assay. Typing of HSV was performed by polymerase chain reaction amplification of HSV-1- and HSV-2-specific DNA polymerase sequences. Results: On entry into the study, 12 (15%) of 82 patients had perianal ulceration and 70 did not. None of the patients in the latter group developed perianal ulcers during the study period, but HSV was isolated at least once from 17 (24%) of them. Nine of the 17 asymptomatic perianal shedders had a mean of 3 perianal swabs collected before the first HSV isolation, and 11 (65%) of 17 had a total of 18 perianal swabs collected 8 to 62 days after the HSV isolation. All postpositive samples were negative for HSV except 1 obtained from a patient 13 days after the first positive sample. Twelve of the 17 asymptomatic perianal shedders of HSV were followed up clinically for 8 to 62 days after the first episode of shedding, and none developed perianal ulceration. Conclusions: We conclude that asymptomatic perianal shedding of HSV is common in patients with AIDS, even among those without a history of perianal HSV lesions. This shedding appears to be short-lived, intermittent, and not associated with early subsequent development of perianal ulcers. These findings present a new perspective on the natural course of perianal HSV infection in patients with AIDS.
