[Various characteristics of the thrombohemorrhagic syndrome in a generalized form of meningococcal infection complicated by toxic-infectious shock].

Blood coagulation was studied in 19 patients with generalized meningococcal infection complicated by toxico-infectious shock (TIS). The outcomes were fatal in 42% of cases. Blood coagulation studies were done on days 1, 2, 3, 5-7 and 19-21 of treatment. Blood coagulability was found to be reduced drastically at the peak of disease: platelet aggregability was depressed substantially, and platelet secretory function showed profound disorders. The recovery of both plasma and platelet parameters of blood coagulation was rather slow. The magnitude of disorders may have a predictive value for the prognosis of the disease.
