Aim To analyze frequency and profile of the lipid-lowering therapy (LLT) in patients with dyslipidemia (DLP) and cardiometabolic diseases (CMD) in a population sample aged 55-84 years at the current time (2015-2017).Material and methods Despite guidelines on DLP treatment and the availability of effective and safe lipid-lowering drugs, control of DPL in primary and secondary prevention of cardiovascular diseases (CVD) is insufficient. Knowledge of the level of pharmaceutical correction of DLP in the Russian population is limited; it requires an LLT assessment in various regions and in a wide age range, and a regular monitoring taking into account changing approaches to the correction of DLP. A random population of men and women aged 55-84 years (n=3 896) was evaluated in Novosibirsk in 2015-2017 (project HAPIEE). A joint DLP category was established as low-density lipoprotein cholesterol (LDL-C) ≥3.0 mmol/l, or total cholesterol (TC) ≥5.0 mmol/l, or triglycerides (TG) ≥1.7 mmol/l, or LLT. The combined group of DLP and CMD included ischemic heart disease (IHD), type 2 diabetes mellitus (DM2), and DLP. Regular LLD treatment for the recent 12 months, excluding the dosage of medicines, was assessed using the Anatomic Therapeutic Chemical (ATC) classification. The conditional control of serum lipids was taken as the achievement of LDL-C <3.0 mmol/l, TC <5.0 mmol/l, and TG <1.7 mmol/l.Results In the study sample, the total prevalence of DLP and CMD was 88 % (82.8 % for men and 91.3 % for women, p<0.001). 48.3% of patients in the IHD group, 35.0% in the DM2 group, 29.4% in the DLP group, and 32.8% in the CMD group took LLT. Control of serum lipids was achieved in 18.3% (37.9 % of patients on LLT) of patients with IHD; 9 % (25.6 % of patients on LLT) of patients with DM2; 7.3 % (24.8 % of patients on LLT) of patients with DLP; and 9.0 % (27.6 % of patients on LLTсреди) in the DLP and CMD group. Women with DM2 and DLP more frequently achieved lipid control than men (p<0.001). 98.7 % of study participants took statins as LLT.Conclusion In the sample of urban population aged 55-84 years in 2015-2017, 90 % of patients had DLP or CMD, and at least 3⁄4 of them required blood lipid control. The lipid control was achieved in every fifth IHD patient and in approximately 40% of those who took LLT. For DM2 or DLP patients, the lipid control was achieved in every tenth patient and in approximately 25% of those receiving LLT. Frequency of lipid control in IHD patients was comparable for men and women; in DM2 and DLP, men less frequently achieved the lipid control than women. About 70% of patients in the combined DLP and CMD group and more than 50% of IHD patients did not take LLT, which considerably contributed to the insufficient lipid control in primary and secondary prevention of atherosclerotic CVDs in this population.
Parenteral nutrition-associated liver disease (PNALD) is a severe complication in patients completely dependent on parenteral nutrition (PN). The gold diagnostic standard, liver biopsy, is associated with significant health risk and therefore its use is limited. MicroRNAs (miRNAs) are small non-coding regulatory RNA molecules with highly tissue-specific expression and the secreted miRNAs may serve as non-invasive diagnostic biomarkers. The aim of this study was to evaluate the expression of a panel of specific miRNAs associated with liver diseases of different origin in PN-dependent adult patients in order to design miRNA panel enabling to precise monitoring of PNALD progression. Twelve PN-dependent patients with short bowel syndrome (SBS) were monitored on three/four-month basis for up to 24 months. Forty-five age- and sex-matched subjects without any known liver pathology served as controls. Specific miRNAs expression was determined by RT-qPCR using TaqMan probes (Thermofisher). Liver function test parameters were determined in certified clinical laboratories. Six of the tested miRNAs exhibited significantly altered expression compared with healthy controls, three of them (MIR122, MIR1273g, and MIR500a) were upregulated while three were down-regulated (MIR505, MIR199a, MIR139). MIR122 positively correlated with serum AST and ALT activities while MIR1273g positively correlated with serum CRP concentration and GGT activity. MIR505, MIR199a, and MIR139 negatively correlated with serum GGT activity. Fluctuation of these parameters well paralleled serum miRNA concentrations in all patients throughout the whole observation period. We identified six miRNAs whose serum concentrations are significantly altered in PN-dependent patients with PNALD and correlate with markers of inflammation, cholestasis or hepatic injury. Their reliability as markers of PNALD progression needs to be further evaluated.

This study evaluated the subacute morphologic alterations in renal artery wall and renal nerves in response to catheter-based renal denervation (RDN) in sheep and also compared the efficiency of single-point and multiple-point ablation catheters. Effect of each ablation catheter approved for the clinical use (Symplicity Flex(TM), Medtronic, Inc., or EnligHTN(TM), St. Jude Medical, INC.) was compared to intact contralateral renal artery in 12 sheep by histopathology and immunohistochemistry evaluation after a 10-day period post-RDN procedure. The safety was verified by extensive evaluation of kidney morphology. Vascular wall lesions and nerve injuries were more pronounced in those animals treated with multi-point EnligHTN catheter when compared with animals treated with single-point Symplicity Flex catheter. However, neither RDN procedure led to complete renal nerve ablation. Both systems, tested in the present study, provided only incomplete renal nerve ablation in sheep. Moreover, no appreciable progression of the nerve disintegration in subacute phase post-RDN procedure was observed. This study further supports the notion that the effectiveness remains fully dependent on anatomical inter-individual variability of the sympathetic nerve plexus accompanying the renal artery. Therefore, new systems providing deeper penetrance to targeted perivascular structure would be more efficient.

Omentin is a protein produced by numerous tissues including adipose tissue. Its concentrations are decreased in patients with obesity, type 2 diabetes mellitus (DM) and coronary artery disease (CAD). Experimental studies suggest that omentin may have anti-inflammatory and insulin-sensitizing properties. In the present study, we measured circulating omentin levels and its mRNA expression in epicardial and subcutaneous fat, intercostal and heart muscle before and after elective cardiac surgery in patients with CAD (CAD+, DM-, n=18), combination of CAD and DM (CAD+, DM+, n=9) or with none of these conditions (CAD-, DM-, n=11). The groups did not differ in baseline anthropometric and biochemical characteristics with the exception of higher blood glucose and HBA(1c) in CAD+, DM+ group. Baseline circulating omentin levels tended to be lower in CAD+, DM- and CAD+, DM+ groups as compared to CAD-, DM- group and cardiac surgery increased its concentration only in CAD-, DM- group. The change in serum omentin levels during surgery inversely correlated with epicardial fat thickness. While baseline omentin mRNA expression did not differ among the groups in any of the studied tissues, its increase after surgery was present only in subcutaneous fat in CAD-, DM- and CAD+, DM- groups, but not in CAD+, DM+ group. Intercostal muscle omentin mRNA expression increased after surgery only in CAD-, DM- group. In conclusion, cardiac surgery differentially affects omentin levels and subcutaneous fat and skeletal muscle mRNA expression in patients without coronary artery disease and diabetes as compared to patients with these conditions.
