[The characteristics of pseudotuberculosis with joint involvement in the presence of chronic opisthorchiasis].

A study was made of the clinical picture, certain laboratory and immunological findings in pseudotuberculosis patients with involved joints in the presence of opisthorchiasis invasion. The patients suffering from pseudotuberculosis and chronic opisthorchiasis frequently demonstrated icteric sclera, erythema nodosum, skin itch, tenderness in the right hypochondrium, hepatomegaly, liquid stool, leukopenia, eosinophilia, hyperbilirubinemia, activation of aminotransferases. Later they showed the diagnostic titers of the indirect hemagglutination test, an increase in disease duration, delayed disappearance of the main clinical symptoms. As compared to patients suffering from arthritides without invasion, the patients with associated pseudotuberculous arthritides and opisthorchiasis demonstrated a higher activity of the inflammatory process in the joints, an increase of the duration and number of polyarthritis relapses, alterations in the immunological indicators (a stable reduction of the T lymphocyte and T helper count as well as a rise of the IgM level during late convalescence).
