Abdominal obesity (AO) is a predictor of cardiovascular disease and diabetes mellitus type 2. The assessment of the disease prevalence and the study of socioeconomic status of people with this phenotype of obesity are necessary to develop effective mechanisms to combat this risk factor in the population. The aim of the study is to determine the prevalence of AO in the population and to assess the association with socioeconomic factors according to the data of the ESSE-RF study (Epidemiology of Cardiovascular diseases in the Regions of the Russian Federation). Materials and methods. The object of the study is a random population sample of men and women aged 25-64 years from 13 regions of the Russian Federation (n=21 817). Abdominal obesity in men was defined as waist circumference (WC) >94 cm, and in women - WC >80 cm. Body mass index (BMI) >30.0 kg/m2 was adopted as the criterion of common obesity. Results and discussion. The prevalence of AO in Russia was 55% (61.8% in women and 44% in men), while the percent of people with obesity, defined by BMI was significantly lower (33.4%). The number of examined patients with AO increased with age among both men and women (p<0.0001). A person with AO more often were people with low and very low income and low education levels (p<0.0001). Direct association between employment status and family status and AO in present study did not find, but WC was statistically significantly important criterion among male workers in comparison with those who never worked (p<0.0001), young men and women married, as well as married men of older age groups (p<0.0001).

Objective. To evaluate the ovarian reserve function in female patients with obesity in comparison with women without obesity. Materials and methods. This study evaluated 500 caucasian women, age 20-30 years, 250 with obesity (body mass index, BMI ≥30 kg/m2) and 250 without obesity (BMI <30 kg/m2). Anthropometrics, serum concentrations of anti-Mullerian hormone (AMH), inhibin B, follicle stimulating hormone, luteinizing hormone, estradiol, progesterone, and testosterone were compared as ovarian volume (cm3) and antral follicle count (AFC), determined by ovarian transvaginal ultrasonography. Results and discussion. We reveal statistically significant difference in following parameters: AMH (2.7±0.47 ng/ml vs. 3.8±0.63 ng/ml; p<0.05), testosterone (1.4±0.3 nmol/l vs. 0.7±0.2 nmol/l; p<0.01), ovarian volume (7.2±1.9 cm3 vs 9.5±1.7 cm3; p<0.05), and AFC (13.3±4.5 vs 20.7±7.2; p<0.01) in obesity group vs. control group respectively. Conclusion. Ovarian reserve function is significantly lower in obese patients than in healthy control subjects of young reproductive age, but ovarian reserve parameters are in normal reference range even in obese patients.

Aim. Determination of desialized apolipoprotein-B-100 (apoB-100) and lipoprotein-containing circulating immune complexes in patients with chronic kidney disease (CKD) in program hemodialysis with type 2 diabetes mellitus. Materials and methods. We examined 81 patients with CKD (50 men / 31 women) treated with program hemodialysis, of which 36 (17/19) with type 2 diabetes mellitus, 45 (33/12) non-diabetic patients. The levels of total cholesterol, triglycerides and desialylated apoB-100 in blood plasma and lipoprotein-containing circulating immune complexes. A color duplex scan of brachiocephalic arteries was used to assess the extent of development of atherosclerosis with the determination of the thickness of the intima-medial complex. Results and discussion. Patients with diabetes had high values of total cholesterol, triglycerides (p<0.05). Duplex scan of brachiocephalic arteries showed an increase in the thickness of intima-medial complex in all patients for program hemodialysis, however, in patients with diabetes, the thickness was 13% higher (p<0.05). In patients with diabetes, plaques with stenosis up to 50% prevail, compared with non-diabetic patients, p<0.05. The incidence was significantly higher for desialized apoB-100 by 46% in patients with diabetes on hemodialysis compared non-diabetic patients (p<0.05). An increase in the level of lipoprotein-containing circulating immune complexes by 39%, (p<0.05) in patients with diabetes mellitus was observed, compared with patients non-diabetic patients. The correlation between desialized apoB-100 and duplex scan of brachiocephalic arteries parameters (r=0.325), as well as between the cholesterol level and stenosis up to 50% (r=0.465) in patients with diabetes mellitus, was found to be of medium strength. The patients with diabetes and CKD, myocardial infarction developed 79% more often than in patients without diabetes (p<0.05). Thus, immunogenic lipid markers of atherosclerosis can be considered both as mechanical factors of atherogenesis and diagnostic and prognostic characteristics in type 2 diabetic patients with impaired renal function and chronic renal insufficiency. The conclusion. Accelerated development of atherosclerosis with diabetes and CKD, confirmed with the help of duplex scan of brachiocephalic arteries, may be associated with an increase in the level of modified low density lipoprotein.

Aim. The analysis clinical features of primary hyperparathyroidism on endocrinology in-patients clinic. Materials and methods. Open retrospective study, included data of patients who were hospitalized at Kirov Regional Hospital with primary hyperparathyroidism from January 01, 2013 to December 31, 2016. Results and discussion. 23 patients were hospitalized. Their age is 24-78 years old (mediana 59 [52; 65] years old). There are 20 (87%) women, and 3 (13%) men. Manifest forms of primary hyperparathyroidism were detected in 18 (78.3%) patients, mild forms - in 5 (21.7%) patients. Pathological fracture had 7 (30.4%) patients including 3 (13%) vertebrae and hip fracture, urolithiasis had 10 (43.5%) persons. High blood calcium or parathyroma in ultra-sound were initially revealed in 8 (34.8%) patients 4 (50%) of them had manifest primary hyperparathyroidism. Period before diagnosis was 2 years and more in 10 (43.5%) patients. Conclusion. Clinical features of primary hyperparathyroidism are prevalence of manifest forms, late diagnosis, and high enough frequent of accidental reveal (including persons with representative symptoms).

Aim. To study the effects of oral hypoglycemic agents that can affect the probability of recurrence of nephrolithiasis. Materials and methods. The article is based on the results of examination and treatment of 315 patients suffering from recurrent nephrolithiasis and medically compensated type 2 diabetes mellitus treated at the N.A. Lopatkin Institute of Urology and Interventional Radiology - the branch of the SMRC of Radiology, Ministry of Health of Russia and D.D. Pletnev City Hospital Moscow Healthcare Department in 2012-2017. The patients were divided into three groups according to the applied tool antidiabetic: metformin, glibenclamide, canagliflozin. The control group consisted of patients receiving insulin therapy. Results and discussion. The propensity of Metformin to reduce the pH of urine, which has a negative impact in the conditions of urate nephrolithiasis, which is most common in the population of patients with type 2 diabetes mellitus. Glibenclamide, on the contrary, somewhat latches urine. But changes in the reaction of urine under the influence of the drug do not go beyond normal values and are not clinically significant. Canagliflozin increases diuresis due to medication induced glycosuria and stimulates renal excretion of uric acid and its salts. However canagliflozin does not cause significant shifts in the pH of urine that may somewhat negates the increased risk of recurrence of urate stone formation in the background of the uricosuric effect of the drug. Conclusion. Drug therapy of type 2 diabetes mellitus significantly affects the properties of urine from patients with nephrolithiasis.

Aim. Assessment of prevalence and risk factors of sleep breathing disorders in patients with acromegaly from Moscow region. Materials and methods. Cardiorespiratory monitoring was executed to 55 patients with acromegaly (18 men and 37 women): 27 patients with de novo disease, 28 patients on treatment of acromegaly (including 18 patietns with uncontrolled and 10 - with controlled acromegaly). All subgroups did not differ on sex, BMI and age. Also 24-hour monitoring of arterial blood pressure was carried out in 39 patients (12 men and 27 women, 14 patients with de novo acromegaly, 15 and 10 patients with uncontrolled and controlled acromegaly, respectively). Results and discussion. The high prevalence of sleep breathing disorders (SBD) was revealed in patients with acromegaly from Moscow Region. SBD was found in 92.6%, 83.5% and 70.0% patients with newly diagnosed, uncontrolled and controlled acromegaly, respectively. The majority of patients had severe/moderate SBD in all subgroups (78.8%, 72.2% and 60.0%, respectively). In patients with newly diagnosed and uncontrolled acromegaly index of apnea-hypopnea (31 and 38.5 respectively), number of apnoe episodes (76 and 72) and saturation level (93% and 93.5%) did not differ significantly while these parameters were better in patients with a controlled acromegaly (apnea-hypopnea index 20, apnea episodes 45.5 and saturation level 95%). The peak of desaturation was subphysiological in 91.7%, 86.7% and 77.8% of patients with newly diagnosed, uncontrolled and controlled acromegaly, respectively. Severity of SBD did not depend on GH and IGF-1 levels as well as acromegaly duration. Such all-population risk factors of SBD as BMI and age were valuable for patients with acromegaly, however gender did not matter. SBD were associated with lack of physiological decrease of systolic and diastolic night BP. Conclusion. Acromegaly per se is a strong risk factor of sleep breathing disorders. The high prevalence of sleep breathing disorders in patients with acromegaly even after achievement of control over a disease emphasized need of specialized treatment of these violations.

In order to optimize the therapy, the functional state of the pancreas (P) and the peculiarities of metabolic activity of intestinal microbiota in adults with cystic fibrosis (CF) were assessed. Materials and methods. 14 CF patients (20-34 years, 7 men, 7 women) were enrolled. In 8 patients, the diagnosis was confirmed in the first year of life on the basis of clinical data, positive sweat test, 5 had genetic confirmation. In 4 patients, the diagnosis was confirmed at the age of 8-13 years and 2 patients aged 18, 27 years. In this group, genetic confirmation was in 4 subjects. In addition to general clinical studies, the level of C-peptide in blood, elastase and the concentration of short chain fatty acids in feces was determined. Results and discussion. Of elastase feces in 9 patients was 5.5±4.7 icg/g, that is revealed severe exocrine insufficiency of the pancreas and in 5 patients the elastase level was normal and amounted to 402±124 icg/g. Deployed the clinical picture of diabetes mellitus was observed in 3 patients. Metabolic activity of the colon microflora as a whole was reduced, the sum of the concentration of short-chain fatty acids (ΣCn) was 6.03±4.11 mg/g at a rate of 10.61±5.11 (p<0.05). At the same time, in some patients (group 1, n=9), who were at the time of the study on antibiotic therapy, the value of ΣCn was 3.32±0.33 mg/g, and in patients receiving probiotic drugs (group 2, n=5), the activity of microflora did not differ from the norm ((ΣCn=11.03±2.01 mg/g). The correlation dependence of the ratio of the total iso-acids fraction in patients with MV to the normal values and the level of fecal elastase (r= -0.46, p=0.049) was revealed. Conclusion. Most patients with CF (64%) diagnosed with exocrine pancreatic insufficiency severe according elastase stool. The activity of faecal elastase correlated with parameters of microbiocenosis, which indicates the necessity of correction is not only functional insufficiency of the pancreas, but also the state of the microbiota.

Urinary albumin excretion (UAE) is widely used in clinical practice as indicator of diabetic kidney disease. According to the classical concept of the natural course of diabetic nephropathy, an increase in UAE usually precedes a decline in renal function. Meanwhile, a growing body of evidences indicates a high prevalence of normoalbuminuric chronic kidney disease (NA-CKD) in diabetic subjects, especially among patients with type 2 diabetes. An increase in NA-CKD prevalence can be results of improved glucose, blood pressure, and lipid control, widespread use of renin-angiotensin system blockers, and smoking cessation. It was shown that NA-CKD is more prevalent among women and is associated with arterial hypertension and coronary artery disease. The renal structure in subjects with NA-CKD is more heterogeneous when compared to patients with increased albuminuria, wherein interstitial changes and arteriolosclerosis could be the principal morphological findings, while signs of glomerulopathy may be absent. The prognostic value of NA-CKD needs to be clarified. It was shown that NA-CKD increases the risk of myocardial infarction, stroke and cardiovascular death in patients with diabetes. The search for alternative diagnostic markers for detecting of diabetic kidney disease in the absence of albuminuria, is of practical importance. The evaluations of the markers of tubular damage and interstitial fibrosis, as well as proteomic approaches, are considered as perspective diagnostic and prognostic options in NA-CKD. The study of pathogenesis, pathology, clinical course of NA-CKD in diabetic patients, as well as the development of more specific diagnostic and treatment options is a challenge for future research.
