RESUMEN
OBJECTIVE: To evaluate the prevalence of anal intraepithelial lesions and associated risk factors in women with cervical neoplasia. METHODS: The present cross-sectional study enrolled patients with intraepithelial or invasive cervical neoplasia who had been referred to the lower genital tract pathology outpatient department of the Instituto de Medicina Integral Prof. Fernando Figueira, Recife, Brazil, between December 1, 2008, and December 31, 2009; patients with HIV infections were excluded. All participants underwent anal cytology and high-resolution anoscopy; sociodemographic and clinical risk factors were identified using multivariate analysis. RESULTS: There were 324 patients included and 37 (11.4%) had anal intraepithelial neoplasia. Factors associated with anal intraepithelial neoplasia in the multivariate analysis were being older than 35 years of age (P=0.002), having completed no more than 4 years of education (P=0.012), anomalous anal cytology (P=0.003), and anomalous high-resolution anoscopy findings (P<0.001); subclinical HPV lesions on vulvoscopy (P=0.057) were not associated with anal intraepithelial neoplasia. CONCLUSION: The prevalence of anal intraepithelial neoplasia was high among patients with cervical neoplasia who did not have HIV, particularly patients older than 35 years.

In our study, we identified a polymorphism (C-607A) in the promoter region of the IL-18 gene that shows different frequencies between human immunodeficiency virus (HIV)-1-infected children and healthy controls in a pediatric Brazilian population. The presence of the -607 C allele correlates to HIV-1 infection and confers an increased risk of infection in subjects carrying the single nucleotide polymorphism.
