T cell-dependent immunodepression in vivo in Schistosoma mansoni infected patients

Abstracts

T-cell function was evaluated in 29 patients with either hepatointestinal or hepatosplenic schistosomiasis by intradermal tests to recall antigens. Immunodepression was detected in 26% of the subjects with hepatointestinal schistosomiasis and in 50% of those with the hepatosplenic form. Cellular immunodepression was related to worm load and spleen size. This non specific T-cell immunodepression may represent a serious constraint to the elimination of intracellular pathogens both in hepatosplenic or hepatointestinal schistosomiasis.

Schistosomiasis; T-cell dependent immunodepression


A imunidade celular foi avaliada em 29 pacientes com as formas hepatoesplênica ou hepatointestinal, da esquistossomose mansoni, através de testes intradérmicos com antígenos não relacionados ao Schistosoma. Imunodepressão foi detectada em 26% dos pacientes com a forma hepatointestinal e em 50% daqueles com a forma hepatoesplênica. A imunodepressão celular foi relacionada com a carga parasitária e o tamanho do baço. Esta imunodepressão celular pode dificultar a eliminação de patógenos intracelulares tanto na forma hepatoesplênica quanto na forma hepatointestinal da esquistossomose.

RESUMO

A imunidade celular foi avaliada em 29 pacientes com as formas hepatoesplênica ou hepatointestinal, da esquistossomose mansoni, através de testes intradérmicos com antígenos não relacionados ao Schistosoma. Imunodepressão foi detectada em 26% dos pacientes com a forma hepatointestinal e em 50% daqueles com a forma hepatoesplênica. A imunodepressão celular foi relacionada com a carga parasitária e o tamanho do baço. Esta imunodepressão celular pode dificultar a eliminação de patógenos intracelulares tanto na forma hepatoesplênica quanto na forma hepatointestinal da esquistossomose.
