RESUMO
Six hundred and ninety three male inmates from three penitentiaries, two (A and B) maximum-security systems and one (C) minimum-security facility, located in Campinas, State of São Paulo, Brazil were studied for the presence of human immunodeficiency virus (HIV) antibodies, using a cross-sectional design. The search for anti-HIV antibodies in 693 samples of sera collected was carried out by two serological tests: (a) the Microparticle enzyme immunoassay-HIV-1 and HIV-2 (MEIA) (Abbott Laboratories) and (b) the Western Blot-HIV-1 (WB) (Cambridge Biotech Corporation) to confirm positive results with MEIA. Sera reactivity for HIV antibodies was 14.4 percent. The highest frequency of anti-HIV antibodies was found in the A and B maximum-security prisons: 17 percent and 21.5 percent, respectively. In prison C, the frequency of reagents was 10.9 percent. Seventy three inmates, initially negative in the MEIA test, were checked again five and seven months later. Three of them, all from the maximum-security facilities, became reactive in the MEIA test, with confirmation in the WB, suggesting that serological conversion had occurred after imprisonment

Alguns virus das familias Retroviridae, tais como, o Virus do Linfoma Humano de Celulas T (HTLV); Herpesviridae, tais como o Virus Citomegalico (CMV) e da Hepatite B (HBV) podem ser co-transmitidos com o Virus da Imunodeficiencia Adquirida (HIV). Uma vez que prisioneiros estao expostos a diversos fatores de risco envolvidos na transmissao do HIV e dos virus acima mencionados, prisioneiros do sexo masculino do Complexo Penitenciario de Campinas, SP, Brasil, incluindo aqueles que eram HIV+ e HIV-, foram examinados para a presenca de anticorpos anti-HTLV-I/II; anticorpos IgG e IgM anti-virus citomegalico e a presenca do antigeno de superficie do HBV (HbsAg). A presenca de anti-HTLV-I/II foi determinada pela tecnica de Western Blot, enquanto IgG e IgM anti-CMV e a pesquisa do HbsAg foram feitas por ensaio Imunoenzimatico (MEIA-Abbott Lab)...
