Production of herpes simplex virus (HSV)–specific interferon‐γ by peripheral‐blood mononuclear cells (PBMCs) of HSV‐seropositive healthy donors and human immunodeficiency virus–infected persons was determined by use of ELISPOT. The mean ± SD number of spot‐forming cells/106 PBMCs was 314 ± 74 in 11 healthy donors, 360 ± 69 in 3 long‐term nonprogressors (LTNPs), 186 ± 52 in 9 newly diagnosed patients, and 181 ± 59 in 33 patients who were receiving highly active antiretroviral therapy (HAART) for a median period of 30 months (range, 1–109 months). In 9 patients monitored prospectively while receiving virologically and immunologically successful first‐line HAART, the number of spot‐forming cells increased by 5.6/month (95% confidence interval, 1.2–9.9 [
]) and 21.3/100 CD4 cells/mm3 gained (95% confidence interval, 13.8–28.7 [
]). Responses were correlated with LTNP status and CD4 cell count.
