SUMMARY This study aimed at estimating the number of cases of non-negative serological reactions to Chagas disease in blood donors at the Blood Center of Botucatu, São Paulo, Brazil, from 2003 to 2010 and at relating them to their cities of origin. Five hundred and seventy-four non-negative results for Chagas disease were evaluated. Of these, 371 (64.8%) were reagent, and 203 (35.4%) were inconclusive. The prevalence of Chagas disease in blood donors was 0.05%. There were, on average, 72 cases/year, and a prevalence of males was observed (64.8%). Forty-three (7.49%) individuals were 18 to 30 years old; 92 (16.02%) were 31 to 40; 147 (25.61%) 41 to 50, and 292 (50.87%) were older than 50 years. It was observed that 29.3% of females with reagent serology were at their fertile age (18 and 45 years). The majority of donors were originally from cities in the southwestern and central regions of São Paulo, but individuals from other states contributed with 20%. The provenance of most donors was the city of Botucatu/SP, followed by the city of Taquarituba/SP. Therefore, the profile of donors at this blood center favors the occurrence of a larger number of non-negative serological reactions. Although there has been a significant reduction in the number of new cases/year for this disease, it is still a public-health problem, and results suggest the need for new epidemiological assessments in the studied region.

Os estudos iniciais sobre a soroprevalência de anticorpos anti-VIH-1 (Ac-VIH) em unidades de hemodiálise no Estado do Rio de Janeiro (RJ) foram feitos em 1985. Os números alarmantes, próximos a 14%, foram atribuídos à má qualidade do sangue obtido de "doadores profissionais" em troca de comida ou dinheiro. Recentemente uma série de medidas foram adotadas na tentativa de reduzir o tráfico de sangue. Nossa investigação objetivou avaliar o impacto destas na soroprevalência de Ac-VIH em duas unidades satélites no RJ. A Clínica Segumed foi uma das unidades estudadas em 1985. Em 1987 realizamos um segundo levantamento no mesmo grupo estudado previamente. A Casa de Saúde Grajaú, inaugurada em 1986 com a maioria dos pacientes novos em diálise, foi estudada em 1988. O teste ELISA HIV-1 foi utilizado como rastreamento. Os resultados positivos foram confirmados com Western blot. Os resultados na Segumed mostraram uma grande diferença entre os dois levantamentos (14,4% vs 3,6%). Os dois casos positivos em 1987 estavam entre os identificados em 1985. Nenhum paciente se infectou entre os dois levantamentos apesar de não se utilizarem medidas de isolamento para os portadores de VIH e do uso de transfusões ter aumentado no período. Na CS Grajaú apenas dois casos foram encontrados (soroprevalência 2,4%) embora um já fosse conhecido desde 1985 quando vivia com um transplante. Uma revisão de estudos semelhantes no RJ e São Paulo parece revelar uma tendência à diminuição das taxas nos últimos anos. Nós concluímos que a chance de contaminação com VIH é atualmente reduzida nos centros estudados e pode estar caindo globalmente no RJ. É possível que a maior vigilância, e até fechamento de bancos de sangue, tenha resultado na melhora da qualidade do sangue no RJ.

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
