The prevalence of diabetes mellitus (DM) in this country as well as throughout the globe has reached epidemic proportions. The register of DM patientsand relevant epidemiological studies are important sources of objective information about epidemiological situation with respect to DM morbidity thatmay be used to predict the prevalence of DM and its complications. The results of a 5-year project and subsequent prospective studies suggest a risein the number of diabetic patients in Russia (3,163,300 as of 01.01.2010). It is expected to increase up to 5.81 mln within the next two decades althoughsome of the patients will never be registered. The actual prevalence of DM complications also exceeds the registered one; they are not diagnosedin 40-55% of the patients. Prospective studies revealed an increased number of DM1 patients with the HbA 1c level

Aim. Comparative assessment of the prevalence of diabetic complications (DC) and the main metabolic indices in adult patients with DM1 and DM2 in the periodfrom 2003 to 2009. Materials and methods. The study based on the Diabet Tsentr mobile module was designed to perform screening (2003) and rescreening (2009) for DC in severalregions of the Russian Federation. Laboratory analyses included measurement of blood HbA 1c , creatinine, urea, total cholesterol levels, and albumin in singlevoidurine samples. The patients underwent fundoscopy, evaluation of all forms of sensory responsiveness, measurement of arterial pressure, and ECG. The resultswere treated with the use of Statistica 6 software. They are presented as median, 25th and 75th percentiles (Me[25%;75%]). The difference between the groups wasregarded as statistically significant at p Results. The prospective study reveled a significant decrease in the prevalence of diabetic cataract from 36.8 to 33.7%, diabetic retinopathy from 41.4 to 31.8%,nephropathy from 39.6 to 30.6%, arterial hypertension from 68.9 to 65.3, angina from 28.8 to 20.5%, myocardial infarction from 7.5 to 5.2% (= 1c level dropped by 0.8 and 0.5% in DM1 and DM2 patients respectively. Mean systolic pressure decreased by 10 and 2 mmHg in thetwo groups. The number of DM1 and DM2 patients with decompensate carbohydrate metabolism decreased by 12.5 and 7.3% respectively. The number of DM2patients in need of insulin and combined therapy increased up to 18.2 and 7.7%. Conclusion. Controlled epidemiologic studies are indispensable for obtaining reliable information about the prevalence of DM and its complications and for updatingregister data. Comparative assessment of the efficiency of diagnostic and therapeutic aid to the patients revealed positive dynamics of morbidity characteristics.

Aim. To study the prevalence of renal lesions in adult patients with type 1 and 2 diabetes mellitus in the Russian Federation. Materials and methods. A total of 7174 patients with DM1 and DM2 were examined in 20 regions of the Russian Federation for blood HbA 1c creatinine,urea, and cholesterol levels, albumin excretion in a single urine sample, AP, and eye fundus condition. Albumin concentration from 20 to 200mg/l was regarded as microalbuminuria (MAU) that above 200 mg/l as proteinuria (PU). The glomerular filtration rate (GFR) was calculated fromCockroft-Gault formula. Statistica-6 program was used for statistical treatment of the results of the study. They are represented as median, 25th and75th percentile values (Me [25%;75%]). Differences between all parameters is considered significant at p Results. Pathologic albumin excretion was documented in 42,1 and 45,3% of the DM1 and DM2 patients. Its prevalence increased with age andDM duration as well as at poor AP and glycemic control. Stage 2 chronic renal disease developed in 16,5 and 23,7%, stage 3 in 4,2 and 6,3%,stage 4-5 in 0,9 and 0,2% of the DM1 and DM2 patients respectively. 15,0 and 41,2% of DM1 and DM2 patients with MAU needed additionalexamination to elucidate non-diabetic origin of CRD. 40% of the DM2 patients with impaired GFR and poor glycemic control had to be transferredto insulin therapy.
