[The prognosis of a protracted course of pseudotuberculosis in chronic opisthorchiasis].

Forty-five pseudotuberculosis patients with concomitant chronic opisthorchiasis were examined at the peak of infection and in early convalescence, as were 30 patients with chronic opisthorchiasis and 30 normal subjects. The immunologic status of pseudotuberculosis patients coursing in the presence of chronic opisthorchiasis was found changed. Reduction of B lymphocyte counts by 1.7 times, of absolute theophyllin-resistant counts by 1.6 times, and of the relative theophyllin-resistant lymphocyte counts by 2 times and elevated levels of circulating immune complexes (by 3 times) and of IgE (by 3.5 times) vs. the norm in the early periods of the disease predict a protracted course of pseudotuberculosis in the presence of chronic opisthorchiasis.
