AB OBJECTIVE: To evaluate the proliferative activity of cervical
intraepithelial neoplasia (CIN) lesions in Human Immunodeficiency Virus
(HIV) seropositive women. METHODS: The proliferative activity of CIN
lesions was measured by nucleolar organizer regions-associated proteins
(AgNORs) count. Twenty-two biopsy specimens of CIN lesions from HIV
positive patients were compared with 22 matched biopsies obtained from
HIV-negative controls. RESULTS: The mean count of AgNORs per cell was
9.5 +/- 3.7 (SD) in HIV-positive patients and 7.6 +/- 2.8 in
HIV-negative controls (P < .0001 by Poisson test of heterogeneity of
counts). The difference in AgNOR counts between the two groups, which
was confirmed by log-linear analysis, persisted within each severity
stratum of CIN and was independent of associated Human Papillomavirus
infection. In HIV-positive patients, log-linear analysis showed that
high grade CIN, presence of HPV infection, and severity of HIV disease
were independently correlated with increased AgNOR counts per cell.
CONCLUSIONS: The results of the present study indicate that the
proliferative activity of CIN lesions of HIV-positive patients was
increased when compared with matched lesions from HIV-negative women.
This finding suggests the possibility of an increased oncogenic
progression of CIN lesions in HIV-positive patients.
