RESUMO
OBJECTIVE: To compare the diagnostic accuracy of the classic Meisels cytologic criteria and the Schneider secondary criteria relative to the hybrid capture method for diagnosing HPV infection. METHODS: This was a retrospective study performed at a public university hospital. A total of 41 patients with a cytologic diagnosis of HPV infection and 40 HPV-negative patients were selected for review of the cervical-vaginal smears seeking to classical and secondary criteria. A single pathologist reviewed the slides in search of the criteria. The classical and secondary cytologic criteria were compared with the hybrid capture for diagnosing HPV infection. Bartleti test was applied for the age analysis, and Fisher's exact test was used to compare proportions. The tests were considered significant when the probability of rejecting the null hypothesis was less than 5% (p < 0.05). RESULTS: The Meisels criteria were less sensitive (34.0%) than the secondary Schneider criteria (57.5%) when compared with the hybrid capture (p < 0.0001), although the specificity of the former criteria was non-significantly higher (91.2% and 67.7%, respectively). In cases of moderate or intense inflammation, the sensitivity and specificity of the Schneider criteria were decreased, 33.3% and 50.0% respectively (p = 0.0115). CONCLUSIONS: Compared with hybrid capture for diagnosis of HPV infection, the sensitivity of the secondary Schneider criteria was higher than the classical Meisels criteria.Moderate or intense inflammation reduces the sensitivity and specificity of the secondary Schneider criteria for diagnosing HPV infection using the hybrid capture as the gold standard.

Objetivo Comparar a acurácia diagnóstica dos critérios citológicos clássicos de Meisels com a dos critérios secundários de Schneider em relação a captura híbrida para o diagnóstico de infecção pelo HPV. Métodos Trata-se de estudo retrospectivo realizado em hospital público universitário. Quarenta e uma pacientes com diagnóstico citológico de infecção pelo HPV e 40 pacientes HPV-negativas foram selecionadas para avaliação dos esfregaços cervicaisvaginais em busca dos critérios clássicos e secundários. Um único patologista reviu as lâminas. Os critérios citológicos clássicos e secundários foram comparados com a captura híbrida para o diagnóstico de infecção pelo HPV. O teste de Bartleti foi aplicado para a análise das idades e o teste exato de Fisher para comparar proporções. Os testes foram considerados significativos quando a probabilidade de rejeitar a hipótese de nulidade foi menor que 5% (p < 0,05). Resultados Os critérios deMeisels forammenos sensíveis (34,0%) que os secundários de Schneider (57,5%) quando comparados com a captura híbrida (p < 0,0001), embora a especificidade dos critérios de Meisels não tenha sido significativamente superior (91,2% e 67,7%, respectivamente). Em casos de inflamação moderada ou intensa, a sensibilidade e especificidade dos critérios secundários de Schneider foram diminuídas, 33,3% e 50,0%, respectivamente (p = 0,0115). Conclusões Comparado a captura híbrida para o diagnóstico da infecção pelo HPV, a sensibilidade dos critérios secundários de Schneider foi maior que a dos critérios clássicos de Meisels. Inflamação moderada ou intensa reduziu a sensibilidade e especificidade dos critérios secundários de Schneider para o diagnóstico de infecção pelo HPV utilizando a captura híbrida como padrão-ouro.
