The in vitro production of α- and γ-interferon (IF) by peripheral blood lymphocytes (PBL) and the concentration of serum IF in 50 patients having hemorrhagic fever with renal syndrome (HFRS), as well as the possibility of the formation of spontaneous IF by PBL and the influence of the patient blood plasma on α-IF genesis, was studied. The development of HFRS was accompanied by a rise in the level of serum IF with different speed, depending on the severity of the disease with simultaneous suppression of the lymphocytes capacity for α- and especially γ-IF production. In cases of moderate and severe forms of the disease no restoration of the IF system occurred by the moment of discharge from the hospital. In a few patients spontaneous IF in low titers was determined. In cases of the moderate form of the disease in the oligoanuretic period and the severe form of the disease in the oligoanuretic and polyuretic periods the patients’ blood plasma essentially suppressed the production of α-IF by PBL.
