RESUMO
Neste estudo, foi estimada a prevalência da infecção pelo HTLV 1/2 em gestantes no Estado de Mato Grosso do Sul, por meio das técnicas ELISA, Western Blot e PCR, em amostras de sangue obtidas por punção venosa periférica. Foram examinadas 116.689 gestantes, sendo diagnosticadas 153 infectadas pelo HTLV 1/2, com prevalência de 0,13 por cento. Deste total, 133 (86,9 por cento) eram do tipo 1 e 20 (11,1 por cento) do tipo 2. Das 153 gestantes, 73,2 por cento eram negras, pardas ou índias, cerca de 90 por cento tinham atividades domésticas e 75,8 por cento (116/153) tinham 7 anos ou menos de escolaridade. As 153 gestantes tiveram 172 gestações, durante o período do estudo, sendo que 164 tiveram acompanhamento. Das gestações acompanhadas, 6,7 por cento (11/164) evoluíram para aborto, 26,8 por cento (41/153) gestantes relataram abortos anteriores, sendo que 31,7 por cento (13/41) apresentaram mais de dois abortos. Co-morbidades foram detectadas em 17 por cento (26/153) sendo 3,3 por cento (5/153) com HIV (p<0,000002). Os autores enfatizam a importância da identificação das gestantes infectadas pelo HTLV1/2 na estratégia de controle e prevenção da doença.
ABSTRACT
In this study, the prevalence of HTLV 1/2 infection among pregnant women in the State of Mato Grosso do Sul was estimated by means of the ELISA, Western Blot and PCR techniques, in blood samples collected by peripheral venous puncture. 116,689 pregnant women were examined and 153 were diagnosed as presenting HTLV 1/2 infection, with prevalence of 0.13 percent. Among these 153 pregnant women, 133 (86.9 percent) had type 1 and 20 (11.1 percent) had type 2; 73.2 percent were black, brown or indigenous; about 90 percent performed domestic activities; and 75.8 percent (116/153) had been to school for seven years or less. The 153 pregnant women had 172 pregnancies during the study period and 164 pregnancies were followed. Out of pregnancies that were followed, 6.7 percent (11/164) evolved to abortion, 26.8 percent (41/153) reported previous abortions and 31.7 percent (13/41) had had more than two abortions. Comorbidities were found in 17 percent (26/153), among whom 3.3 percent (5/153) had HIV (p<0.000002). The authors emphasize the importance of identifying pregnant women with HTLV 1/2 infection, as a strategy for disease control and prevention.
