[The function of the hypophyseal-thyroid system in chronic opisthorchiasis and its combination with the Salmonella typhi carrier state].

The hormonal function of the hypophysis and thyroid (TTG, T3, T4) and its dependence on hepatobiliary function, examined by hepatobiliscintigraphy, were studied by radioimmunoassay in 71 patients with chronic opisthorchiasis and in 18 chronic carriers of Salmonella typhi. in both groups. The decrease of T3 and T4 in the presence of normal TTG level was found. The imbalance of thyroid hormones activity is likely to be associated with hepatobiliary dysfunction. In chronic opisthorchiasis the hormonal disturbance may be one of the factors favouring the S. typhi carriership.
