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%. Deste total, 133 (86,9%) eram do tipo 1 e 20 (11,1%) do tipo 2. Das 153 gestantes, 73,2% eram negras, pardas ou índias, cerca de 90% tinham atividades domésticas e 75,8% (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% (11/164) evoluíram para aborto, 26,8% (41/153) gestantes relataram abortos anteriores, sendo que 31,7% (13/41) apresentaram mais de dois abortos. Co-morbidades foram detectadas em 17% (26/153) sendo 3,3% (5/153) com HIV (pIn 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%. Among these 153 pregnant women, 133 (86.9%) had type 1 and 20 (11.1%) had type 2; 73.2% were black, brown or indigenous; about 90% performed domestic activities; and 75.8% (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% (11/164) evolved to abortion, 26.8% (41/153) reported previous abortions and 31.7% (13/41) had had more than two abortions. Comorbidities were found in 17% (26/153), among whom 3.3% (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.
