ABSTRACT

Adherence index, superoxide and TNF-alpha production in monocytes, with or without tuftsin treatment, were investigated in hepatosplenic schistosomiasis mansoni bearers with splenectomy with or without autologous implantation of spleen tissue. Three groups were evaluated: Healthy volunteers control group (CG) (n=12); Splenectomy with seft auto-transplant AG (n=18) and Splenectomy without auto-transplant WAG (n=9). Adherence index and TNF-alpha did not differ among the groups. Superoxide production was similar in CG and AG, in the 1st hour after cell stimulation. SP was larger in each hour time in CG and AG groups as compared WAS group. TT recovered normal pattern of SP in AG comparable with levels found in CG, with increase from the 1st to 2nd hour. However, TT did not alter SP in WAG, which remained reduced in all time points. Autologous implantation of spleen tissue seems to contribute for recovery and maintenance of the evaluated immunological reactions, which might be important in response to infections.

ABSTRACT

Investigamos em portadores de esquistossomose hepatoesplênica após esplenectomia com ou sem auto-implante esplênico: índice de aderência, produção de superóxido (SP) e de TNF-alfa em monócitos, tratados ou não com tuftsina. Avaliamos três grupos: voluntários sadios CG (grupo controle) (n=12); esplenectomizados com auto-implante AG (n=18) e esplenectomizados sem auto-implante WAG (n=9). índice de aderência e TNF-alfa não diferiram entre os grupos. SP foi semelhante em CG e AG na 1ª hora após estimulação celular. SP foi maior em todos intervalos de tempo nos grupos CG e AG, comparados ao WAG. O tratamento com tuftsina recuperou o padrão de normalidade de SP em AG, com aumento da 1ª para a 2ª hora nos níveis do CG. O tratamento com tuftsina não alterou SP em WAG, permanecendo reduzida em todos intervalos. O auto-implante esplênico parece recuperar e manter os parâmetros imunológicos avaliados, que têm participação importante na resposta do hospedeiro às infecções.
