ABSTRACT
Neurocysticercosis (NCC) has attained the importance of one of the most common cause of focal brain lesions in patients infected with HIV (human immunodeficiency virus). Adequate data regarding the rate of this co-infection is lacking. Therefore, the present study was carried out to determine the prevalence of cysticercosis among HIV patients residing in Puducherry or its neighboring districts of Tamil Nadu State, India. A total of one hundred blood samples were collected from HIV seropositive cases visiting JIPMER hospital, Puducherry, between June 2007 and May 2008. Enzyme immunotransfer blot (EITB) and enzyme linked immunosorbent assay (ELISA) were used to demonstrate anti- T. solium larval stage antibodies and Co-agglutination (Co-A) test was used to detect T. solium larval stage antigens in sera. Two HIV seropositive cases were found positive for anti-T. solium larval stage antibody by EITB and four were positive by ELISA. Only one sample was positive by both EITB and ELISA. No serum sample was found positive for T. solium larval stage antigen by Co-A test. The overall seropositivity detected by all the methods was 5 percent in this study group. The accurate clinical diagnosis of NCC in HIV is difficult due to deranged immunological parameters in the HIV infected patients. The results of this study provides important data on the prevalence of cysticercosis in HIV positive patients in Puducherry and neighboring areas which was previously unknown. This study will also increase awareness among physicians and public health agencies about T. solium cysticercosis in the selected group.
RESUMO
Neurocisticercose (NCC) tem alcançado a importância de uma das mais comuns causas de lesões focais no cérebro em pacientes infectados pelo HIV (vírus da imunodeficiência adquirida). Dados adequados relativos à frequencia desta co-infecção estão faltando. Portanto, o presente estudo foi realizado para determinar a prevalência da cisticercose entre pacientes com HIV residindo em Puducherry ou distritos vizinhos do Estado de Tamil Nadu, India. Um total de cem amostras foram coletadas de casos soropositivos do Hospital JIPMER, Puducherry, entre junho de 2007 e maio de 2008. "Enzyme immunotransfer blot" (EITB) e ELISA foram utilizados para demonstrar anticorpos contra a fase larval do T. solium. Testes de co-aglutinação (Co-a) foram usados para demonstrar antígenos da fase larval do T. solium no soro. Dois casos HIV soropositivos foram positivos para anticorpos contra a fase larval do T. solium por EITB e quatro foram positivos por ELISA. Somente uma amostra foi positiva por ambos EITB e ELISA. Nenhuma amostra de soro foi positiva para antígeno da fase larval do T. solium pelo teste Co-a. A soropositividade total detectada por todos os métodos foi 5 por cento neste grupo de estudo. O diagnóstico clínico exato de NCC em HIV é difícil devido aos desordenados parâmetros imunológicos nos pacientes infectados pelo HIV. Os resultados deste estudo fornecem dados importantes sobre a prevalência da cisticercose em pacientes HIV positivos em Puducherry e áreas vizinhas que eram previamente desconhecidos. Este estudo também aumentará a atenção dos médicos e agências de saúde pública sobre a cisticercose por T. solium em grupo selecionado.
