[Selection of Patients with Resistant Arterial Hypertension for the Catheter-Based Renal Sympathetic Denervation].

PURPOSE: elaboration of algorithm for selection of patients with resistant arterial hypertension (AH) for Catheter-Based Renal Sympathetic Denervation (CBRSD). MATERIALS AND METHODS: We examined 284 patients with resistant AH. On stage 1 we excluded most frequent causes of secondary AH. In 247 patients (86.9 %) we established secondary character of AH, in 37 patients (13.1 %) AH was found to be essential. On stage 2 patients with essential AH were given 3-5 component hypotensive therapy. At the background of this therapy we conducted 24­hour ambulatory blood pressure monitoring (ABPM). CBRSD procedure was considered indicated if according to ABPM average 24­hour blood pressure (BP) was above 150 and 100 mm Hg, and 24­hour elevated BP load exceeded 60 %. In 13 of 37 patients (35 %) BP level satisfied these conditions. For CBRSD we used high frequency generator. Ablation was performed using the Symplicity Catheter. Results were assessed in 1, 2, 9, 12, and 28 months. RESULTS: Target BP level at the background of minimal doses of hypotensive drugs was achieved in 11 patients (85 %), what was confirmed by ABPM data. Levels of mean 24-4 hour systolic and diastolic BP significantly decreased from 173.9±14.9 to 143±21.3, р<0.05, and from 108.2±8.7 to 91.4±13.8 mm Hg., р<0.05, respectively. Index of elevated systolic BP time decreased from 78.2±14.6 to 49.8±29.6 %, р<0.05. Best effect was achieved in patients with AH duration before the procedure less than 7 years. None of the patients had episodes of cerebral vascular insufficiency or heart failure progression. CONCLUSION: While determining indications to bilateral CBRSD one should be governed by such criteria as exclusion of symptomatic AH and objective proofs of AH resistance (according to ABPM at the background of hypotensive therapy).

[The choice of surgery in patients with diffuse toxic goiter]. / Vybor ob''ema operatsii u bol'nykh diffuznym toksicheskim zobom (s kommentariem).

AIM: to define clear individual indications for different operations for diffuse toxic goiter by research of immunological markers of thyrotoxicosis recurrence probability. MATERIAL AND METHODS: Long-term results of survey and treatment of 215 patients with diffuse toxic goiter are presented. Patients were divided into 2 groups. The 1st group consisted of 31 patienrs who underwent conventional partial thyroidectomy. Group 2 included 184 patients. They were divided into 2 subgroups depending on type of surgery. Subgroup A included 59 patients after partial thyroidectomy and subgroup B - 125 patients after total thyroidectomy. In group 2 surgery was defined based on only level of antibodies against TSH-receptors. RESULTS: Recurrence incidence was 16 and 0% in groups 1 and 2 respectively. CONCLUSION: In patients with diffuse toxic goiter partial thyroidectomy is possible if normal titer of antibodies against TSH-receptors is present (<1.5 U/l). Total thyroidectomy is advisable in titer ≥1.5 U/l.

[Markers of endocrine system and inflammation as prognostic risk factors of vascular complications of type 2 diabetes mellitus].

The high risk of cardiovascular complications in patients with type 2 diabetes mellitus is a key problem in modern medicine. In this review, the basic risk factors of vascular complications in diabetes mellitus are described and their prognostic value analysed. Special attention is paid to the evaluation of the role of adipose tissue hormone adiponectin. The anti-inflammatory properties of adiponectin suggest its protective action against atherosclerosis and cardiovascular complications. In this article, we review a number of studies on the relationship between adiponectin and the main cardiovascular risk factors in patients with type 2 diabetes mellitus.
