PrevalÃncia de HPH e lesÃes intraepiteliais escamosas em gestantes / Prevalence by HPV and squamous intraepithelial lesions in pregnant women

Elizabeth Dell Orto Vieira 18 December 2008 (has links)
CoordenaÃÃo de AperfeiÃoamento de Pessoal de NÃvel Superior / Estudo de prevalÃncia (estudo transversal) sobre infecÃÃo por HPV em colo uterino de gestantes, avaliando o(s) subgrupo(s) de HPV mais prevalentes e a associaÃÃo quanto ao desenvolvimento de lesÃes intraepiteliais escamosas. A metodologia constituiu-se de questionÃrio aplicado diretamente a 272 gestantes, independente da idade gestacional e de estarem sintomÃticas ou nÃo na primeira consulta de prÃ-natal, alÃm da coleta de material cÃrvico-vaginal (paredes vaginais, ectocÃrvice e endocÃrvice) para realizaÃÃo de Citologia oncÃtica convencional pelo mÃtodo de coloraÃÃo proposto por Papanicolaou e do teste de Captura HÃbrida IIÂ. Procedeu-se a seguir a identificaÃÃo das lesÃes intraepiteliais escamosas e da presenÃa do vÃrus HPV de alto, baixo e mÃdio risco oncogÃnico. Os achados da Captura HÃbrida IIÂ foram correlacionados com os achados citolÃgicos, comparando-se a freqÃÃncia dos resultados anormais nos dois mÃtodos. Procedeu-se tambÃm a associaÃÃo com aspectos biossociais que pudessem interferir na infecÃÃo produzida pelo HPV e no possÃvel desenvolvimento de lesÃes intraepiteliais escamosas. Realizaram-se anÃlises de correlaÃÃo univariada e bivariada, com cÃlculo do Qui-quadrado de Pearson e valor p< 0,05. Utilizou-se tambÃm de regressÃo logÃstica para estimar a magnitude das associaÃÃes. A prevalÃncia de infecÃÃo por HPV e citologias oncÃticas anormais foi de 32,3% e 14,0 % respectivamente. Os subgrupos de HPV de alto risco foram mais prevalentes (27,6%) do que os de baixo e mÃdio risco (18,4%) e a sua associaÃÃo mostrou-se estatisticamente significativa (p<0,05). A associaÃÃo da infecÃÃo genital por HPV de alto risco com lesÃes intraepiteliais escamosas descritas na Citologia oncÃtica convencional foi mais prevalente (8,5%) do que com HPV de baixo de mÃdio risco (5,6%) e teve significÃncia estatÃstica (p<0,05) / This work studies the prevalence (cross sectional) on infection by HPV in uterine cervical of pregnant women evaluating the subgroups of HPV more prevalents and the association in relation to the development of squamous intraepithelial lesions. The methodology was constituted of questionary applied to 272 pregnant women independent of pregnant age and of being symptomatic or not in the first medical advice of prenatal besides the collect of cervico vaginal material (vaginal walls, ectocervix and endocervix) to the achievement of conventional oncotic cytology by the method of coloration proposed by Papanicolaou and the test of Capture Hybrid IIÂ. Then it was proceeded the identification of squamous intraepithelial lesions and the presence of HPV virus of high, low and medium oncogenic risk. The results of Capture Hybrid IIÂ were correlated with the cytologic discoveries comparing the frequency of anormal results in both methods. It was also proceeded the association with biosocial aspects which could interfere in the possible development of squamous intraepithelial lesions. The analysis of univariable and bivariable correlations were accomplished with calculus of Qui-squared of Pearson and value p<0,05. The logistic regression was used to estimate the importance of associations. The prevalence of infection by HPV and anormal oncotic cytologies was about 32,3% and 14,0% respectively. The sub groups of HPV of high risk were more prevalent (27,6%) than the ones of low and medium risk. (18,4%) and their association showed to be statistically significant (p< 0,05). The association of genital infection by HPV of high risk with squamous epithelial lesions described on conventional oncotic cytology was more prevalent (8,5%) than with HPV of low and medium risk (5,6%) and had statistical importance (p< 0,05)
