Abstract

MENDES, Camila Figueira et al. Micronuclei in uterine cervical cells of women HIV+ according to immunocompetence markers. Rev. Bras. Ginecol. Obstet. [online]. 2011, vol.33, n.10, pp.305-309. ISSN 0100-7203.  https://doi.org/10.1590/S0100-72032011001000006.

PURPOSE: to investigate the micronucleation (MN) of exfoliated cells from the uterine cervix of HIV+ women according to immunocompetence status. We investigated the clinical conditions of immunocompetence by analyzing the levels of CD4+ lymphocytes and viral count for HIV (VC). METHODS: biological material was collected from 23 HIV+ patients whose cervical oncologic cytology results were negative. They were patients from the STD/AIDS-FCMS-PUCSP who underwent a cytobrush collection in the squamous columnar junction. Similar material was obtained from 19 healthy control women. The material, about 2000 cells per patient, was processed for cytology using light microscopy and an immersion objective. To analyze the immunological status of  HIV+ patients we used CD4+ count and VC. Statistical analysis was performed using the Χ2 and Kolmorogov-Smirnov tests. RESULTS: twenty-three pacients composed the group of HIV+ women and 19 composed the control group. We found micronuclei (MN) in all HIV+ patients and in 84.2% of the control group. In 17 73.9% of the HIV+ patients and in 5.2% of the control group we found more than 7 MN cells. MN tended to occur more among women with poorer immunological status in the HIV+ group. CONCLUSIONS: HIV+ patients in the AIDS phase have a higher prevalence of micronucleated cells, as opposed to a control group. Also, the frequency of MN was associated with worse conditions of immunosuppression.
