title: Highly active antiretroviral therapy enhances regression of cervical intraepithelial neoplasia in HIV-seropositive women.
abstract: OBJECTIVE
  This study was undertaken to investigate the impact of highly active antiretroviral therapy (HAART) on the regression of cervical intraepithelial neoplasia (CIN) in HIV-infected women.
  
  
  METHODS
  Prospective study of 168 HIV-infected women with evidence of CIN until regression to a lower grade or to normality (end-point) or until surgical treatment or last visit. Ninety-six patients received HAART.
  
  
  METHODS
  Women were examined every 6 months by Papanicolaou smears, colposcopy, and biopsy if required. The probability of CIN regression was calculated using survival analysis. HAART was entered as a time-dependent covariate according to the date of first prescription.
  
  
  RESULTS
  Regression of CIN was observed in 67 (39.9%) women. The probability of regression at 12 months was significantly higher for high-grade CIN [23.8%; 95% confidence interval (CI), 14.2-33.5] than for low-grade lesions (14.8%; 95% CI, 7.0-22.6) (P = 0.04). The risk of regression of CIN was twice as high in women receiving HAART as compared with women not receiving HAART (relative hazard of regression, 1.93; 95% CI, 1.14-3.29). There was a trend for a larger increase in CD4 cell counts among those women taking HAART and who showed regression as compared with those who did not regress.
  
  
  CONCLUSIONS
  The positive impact of HAART on CIN regression may be associated with some restoration of specific immune reactivity. This is not sufficient enough, however, to modify the gynecological follow-up of HIV-infected women.
