Abstract

The mean counts of Langerhans' cells were evaluated in cervical biopsies obtained from 30 patients with human immunodeficiency virus (HIV) infection and cervical intraepithelial neoplasia (CIN) and from 30 HIV-seronegative control patients. Each HIV-seronegative control was matched to a seropositive case with respect to grade of CIN, age, and smoking habits. Langerhans' cells were identified by immunohistochemical staining for S-100 protein. In situ hybridization with biotinylated probes was performed to detect human papillomavirus (HPV) DNA 6/11, 16/18, and 31/35/51. The mean counts of S-100 positive cells per 100 basal cells were lower in HIV-seropositive patients than in controls (0.99 ± 0.08 vs 1.9 ± 0.2 P = 0.024). These differences occurred independent of any coexisting HPV infection. Positive correlations between S-100 positive cell counts and CD4+ and CD8+ cell counts were found in HIV-infected women. AIDS patients had lower Langerhans' cell counts compared both to patients with AIDS-related complex or asymptomatic HIV infection. Our results suggest that local cervical immunity, as evaluated by Langerhans' cell counts, is impaired in HIV-seropositive women. The severity of impairment seems to correlate with the stage of the HIV disease.
