RESUMO

OBJETIVO:

O objetivo foi descrever a distribuição dos genótipos do papilomavírus humano e a frequência de infecções por múltiplos genótipos, bem como avaliar a associação entre genótipos de papilomavírus humano, faixa etária e resultados cito-histopatológicos.

MÉTODOS:

Estudo retrospectivo de corte transversal realizado entre junho de 2010 e outubro de 2013 em Salvador, Bahia, Brasil. Foram revisados 351 prontuários de mulheres com genotipagem positiva pelo teste PapilloCheck(r), usado para detectar 24 tipos de papilomavírus humano. Os achados cito-histopatológicos foram classificados em grupos de achados negativos para neoplasia (exames citopatológico e histopatológico negativos), lesão de baixo grau (achado citopatológico - lesão intraepitelial de baixo grau - ou achado histopatológico - neoplasia intraepitelial cervical grau 1, neoplasia intraepitelial vaginal grau 1 ou condiloma e lesão de alto grau (achado citopatológico - lesão intraepitelial de alto grau - ou histopatologia com laudo maior ou igual a neoplasia intraepitelial cervical grau 2 ou neoplasia intraepitelial vaginal grau 2).

RESULTADOS:

O genótipo de alto risco mais frequente foi o HPV 16, com 18,5%; intervalo de confiança de 95% (IC95%) 14,6-23,0, seguido pelo HPV 56 (14%; IC95% 10,5-18,0) e o HPV 39 (13,4%; IC95% 9,5-16,8). O HPV 18 (5,4%; IC95% 3,3-8,3) esteve entre os menos comuns. Entre os tipos de baixo grau, o HPV 42 (15,7%; IC 95% 12,0-20,0), o HPV 6 (11,4%; IC95% 8,3-15,2) e o HPV 44/55 (11,1%; IC95% 8,0-14,9) foram os mais encontrados, enquanto o HPV 11 (2,8%; IC95% 1,4-5,2) foi o menos frequente. A proporção do HPV 16 aumentou com a severidade das anormalidades cito-histopatológicas de 13,8% (12/87) nas lesões de baixo grau para 42,4% (14/33) nas lesões de alto grau. Houve ...
ABSTRACT

PURPOSE:

The aim of this study was to evaluate the human papillomavirus genotypes and the frequency of multiple human papillomavirus infections, as well as to assess the association between human papillomavirus genotype, cyto-histopathological abnormalities and age range.

METHODS:

A retrospective cross-sectional study was carried out between June 2010 and October 2013 in Salvador, Bahia, Brazil. We analyzed 351 results of positive human papillomavirus genotyping performed using the PapilloCheck(r) test, designed to detect 24 human papillomavirus types. The cyto-histopathological abnormalities were classified as negative (negative cytology and histopathology), low-grade lesions (cytologic low-grade squamous intraepithelial lesion diagnosis or histopathologic cervical intraepithelial neoplasia 1 or vaginal intraepithelial neoplasia 1 diagnosis) and high-grade lesions (cytologic high-grade squamous intraepithelial lesion diagnosis or histopathologic cervical intraepithelial neoplasia 2+ or vaginal intraepithelial neoplasia 2+ diagnosis).

RESULTS:

The most frequently detected high risk human papillomavirus genotype was HPBV 16, with 18.5%, 95% confidence interval (95%CI) 14.6-23.0, followed by HPV 56 (14%; 95%CI 10.5-18.0) and HPV 39 (13.4%; 95%CI 9.5-16.8). HPV 18 (5.4%; 95%CI 3.3-8.3) was among the least frequent types. Among the low risk types, HPV 42 (15.7%; 95%CI 12.0-20.0), HPV 6 (11.4%; 95%CI 8.3-15.2) and HPV 44/55 (11.1%; 95%CI 8.0-14.9) were the most frequent, while HPV 11 (2.8%; 95%CI 1.4-5.2) was the least common. The proportion of HPV 16-positive women increased with severity of cyto-histopathological abnormalities 13.8% (12/87) in low-grade lesion and 42.4% (14/33) in high-grade lesion. There was association between low- or high-grade cyto-histopathological lesion and the high risk genotypes, HPV16, HPV 52, HPV 73 and HPV 82, and the low risk type, HPV 43. Women under 30 years showed a significantly higher frequency ...
