The purpose of the research to create a concept for diagnostics and therapy of hemostasis disorders of patients with severe leptospirosis.Patients and Methods. The study included 474 patients with severe serologically confirmed leptospirosis with a favorable outcome of the disease and 31 patients with fatal outcome (total 505 people). Variant of coagulopathy was determined by using a set of special methods for studying hemostasis. The influence of platelet concentrate transfusion, plasma exchange and various tactics of glucocorticoid therapy on patient survival and correction of hemostasis disorders was evaluated. Survival analysis was made using Kaplan-Meyer method with a Cox proportional intensity model. Relative risk (RR) was calculated with a 95% confidence interval (CI).Results: the use of early diagnosis of coagulopathy variants and the use of a differentiated therapy regimen in the choice of the variant of hemostasis disorder led to a decrease of mortality from 16.45% to 11.5% and decrease in the consumption of platelet concentrate and fresh frozen plasma.Conclusion: patients with severe leptospirosis develop a multivariate hemostatic pathology: isolated thrombocytopenia (38%) with thrombotic microangiopathy (20,5%), disseminated intravascular coagulopathy (37,1%), uremic coagulopathy (4,9%), hepatic coagulopathy (3,4%). Plasma exchange in thrombotic microangiopathy is pathogenetically justified. Also, plasma exchange is pathogenetically justified in order to reduce plasma volume in DIC syndrome with consumption coagulopathy and hepatic coagulopathy. The use of GCS in isolated thrombocytopenia can be effective and safe in both “medium doses” and in the form of “pulse therapy” if the following conditions are met: acute renal injury (AKI) III stage according to AKIN and the absence of renal replacement therapy (RRT). The main indication for platelet concentrate transfusion in severe leptospirosis is extremely severe thrombocytopenia (grade 4) with active life-threatening bleeding at the time of transfusion.
