Human immunodeficiency virus (HIV-1)-infected subjects with acquired immunodeficiency syndrome (AIDS) are often infected with multiple pathogens. In particular, HTLV-I and HTLV-II infections have been found more frequently in AIDS patients than in asymptomatic individuals in Europe and Japan. We carried out a serosurvey among asymptomatic HIV-1-infected subjects in São Paulo, Brazil and compared our results with those of other investigators. In this study, we found HTLV infection in 1.5% of 266 asymptomatic and 14% of 28 AIDS patients. Epidemiological data obtained from patients pointed out the use of intravenous drugs as the principal risk factor for acquiring retroviruses. In conclusion, our results are in accordance with other studies done in Brazil and elsewhere where the principal risk group for HIV/HTLV-I/II coinfection was IDU.
患有获得性免疫缺陷综合征（AIDS）的人类免疫缺陷病毒（HIV-1）感染受试者常感染多种病原体。特别是，在欧洲和日本，与无症状个体相比，艾滋病患者中HTLV-I和HTLV-II感染更为常见。我们对巴西圣保罗无症状的HIV-1感染受试者进行了血清学调查，并将我们的结果与其他研究者的结果进行了比较。在本研究中，我们在266名无症状患者中发现1.5%感染HTLV，在28名艾滋病患者中发现14%感染HTLV。从患者获得的流行病学数据指出，静脉注射毒品是感染逆转录病毒的主要危险因素。总之，我们的结果与巴西及其他地区的其他研究一致，在这些研究中，HIV/HTLV-I/II合并感染的主要风险群体是静脉注射毒品者。
