Objectives - to work out a prognostic method, based on clinical and laboratory data, which can predict the development of lipid distress syndrome in patients with chronic viral hepatitis C. Material and methods. We studied the outcomes of chronic viral hepatitis C with respect to development of lipid distress syndrome in 267 patients who did not receive antiviral therapy during the observation period lasting for 1 to 7 years. Results. Discriminant function analysis of the data acquired after examination of 167 patients helped us to work out a discriminative model of predicting the development of lipid distress syndrome in patients with chronic viral hepatitis C in the absence of antiviral therapy. Crosschecking of prediction accuracy was carried out on the data of examination of other 100 patients. Conclusion. The designed technique for predicting the development of lipid distress syndrome in patients with chronic hepatitis C is characterized by point estimates of sensitivity and prognostic value of the negative result equal to 100%.

Objectives to develop a method of early differential diagnosis of the hemorrhagic fever with renal syndrome (in 3 days after the onset) from other infectious and non-infectious diseases on the basis of mathematical-statistical analysis of clinical, functional and instrumental data. Material and methods. The study presented a complex clinical, functional and ultrasound examinations of 276 patients with various infectious and non-infectious diseases performed within 4 or 5 days from the onset of the disease. Results. Based on the discriminant analysis of the obtained data, a discriminant model for early differential diagnosis of hemorrhagic fever with renal syndrome was developed. Conclusion. The accuracy index of the differential diagnosis of HFRS using the developed discriminant model is 96%.
