Family occurrence of schistosomal hepatosplenomegaly and maternal effect

In this paper we present a study of members of 265 nuclear families, aged six or more. This study is based of family heredograms, and takes into account the clinical form ofschistosomiasis observed before treatment with oxamniquine. The probability of occurrence of two or more cases ofhepatosplenomegaly is low, notwithstanding the fact that it was observed in 38 families. Even less frequent is the occurrence of three or more cases observed in 17 families (P=0.002). The concentration of the hepatosplenic form was higher among siblings than it was among mothers and children, or fathers and children. It was found to be not significant between husband (father) and wife (mother). These observations reinforce the evidence for the presence of a genetic component in susceptibility to the hepatosplenic form of the disease. In cases in which the mother was hepatosplenic there was a higher incidence of hepatosplenic children; the relative risk was a least five times higher than in those in which the father was the affected member (the maternal effect). In cases where both members were affected by the hepatointestinal form, the risk to the filial generation was similar to that of the population in general. Thus, in the process towards severe forms of Schistosomiasis mansoni, pre and post natal factors might be involved.

Busca retrospectiva da transmissão maternal da infecção chagásica em pacientes na fase crônica

Avaliamos a transmissão maternal do Trypanosoma cruzi em 278 filhos de 145 mães com a doença crônica causada por esse protozoário, nascidos após o estabelecimento do diagnóstico materno. Usamos, nas mães e nos filhos, provas sorológicas como base do objetivo do estudo. Verificamos que ocorreram apenas duas veiculações pela modalidade citada (2/278 = 0,7%). Como houve amamentação, não foi possível diferenciar, nesses casos, a transmissão congênita da adquirida pelo leite, mas, de qualquer forma, processou-se transmissão maternal, que constitui uma das modalidades alternativas de infecção pelo Trypanosoma cruzi. A metodologia empregada é mais uma dentre as diversas propostas para aquilatar a prevalência desse tipo de propagação do Trypanosoma cruzi. Ao lado da constatação fundamental, registramos fatos relacionados com a gestação, parto, puerpério, abortamento, prematuridade, nati-neomortalidade e aleitamento materno, que podem representar subsídios para melhores interpretações sobre o assunto.

Chagas' disease: study of congenital transmission in cases of acute maternal infection

We studied three pregnant women with acute chagasic infection. Two patients, infected in the third trimester of pregnancy, had uninfected children. The third patient, infected earlier, had an infected newborn. These results encourage research on risk factors of transmission and on medical decisions concerning pregnant women with acute Chagas' disease.
