Aim. Identification of a complex of clinical and anamnestic predictors of an unfavorable long-term prognosis in patients with heart failure with low left ventricular ejection fraction and an implanted cardioverter-defibrillator (ICD).

Materials and methods. In 260 patients with heart failure with low left ventricular ejection fraction and ICD included in the ”Kuzbass Register of Patients with ICD”, data were obtained on the status of alive/dead, causes of death and cardiovascular events during a 4-year follow-up period. The clinical-instrumental and socio-demographic parameters entered into the register before ICD implantation were used to compile a prognostic regression model.

Results. A total of 348 cardiovascular events (endpoints) were recorded, of which 54 were deaths. The main cause of death in 48 (88.9%) patients was acute decompensated heart failure. According to the multivariate regression analysis, the factors that increase the risk of an unfavorable long-term outcome included in the prognostic model were: the level of systolic pressure in the pulmonary artery, the thickness of the interventricular septum, social status, the presence of chronic obstructive pulmonary disease, the low ejection fraction of the left ventricle and the absence of a renin-blocker angiotensin-aldosterone system (model sensitivity – 70%, specificity – 75.9%, AUC=0.8).

Conclusion. The use of a predictive model in clinical practice will make it possible to personalize approaches to making a decision on the need for ICD implantation and further monitoring of patients in order to improve their survival.

Aim. To compare risk factors for new-onset diabetes after transplantation (NODAT) among renal transplant recipients (RTRs) from 1989 to 2018 in the City Clinical Hospital №52, with a systematic analysis of published studies on this topic.

Materials and methods. In a 30-year (1989–2018) retrospective study, we found statistically significant differences in age, gender, polycystic kidney disease, cadaveric kidney, cyclosporine, i-mTOR, and steroids between two groups of recipients with and without NODAT. Patients with NODAT were older, more male, more likely to have polycystic kidney disease and deceased donor kidneys, and more likely to be treated with cyclosporine, i-mTOR, and steroids (p<0.05). We conducted a meta-analysis to evaluate the impact of these indicators on the development of NODAT. MEDLINE, Scopus, and the Cochrane Central Register of Controlled Trials were searched for eligible case-control studies of risk factors for NODAT in RTRs published between 1990 and 2019. Meta-analysis of proportions was performed using the Freeman–Tukey transformation to calculate weighted summary proportions from a fixed and random effects model.

Results. A total of 13 case-control studies were included in the meta-analysis. Of the total 849 studies found, 13 were included in the systematic review and meta-analysis, including ours, with a total of n=6797 RTRs, of which n=1305 patients with NODAT and n=5492 without NODAT. A wide range of data was recorded for the analysis of the incidence of NODAT (6.5–50.7%), with an average of 17.9% (fixed model) or 24.3% (random model). The proportion of NODAT recorded in the Russian registry of the City Clinical Hospital №52 was lower (11.5%), however, the data in the analyzed studies were highly heterogeneous: I²=98.14%, 95% CI: from 97.61 to 98.55, p<0.0001, Begg's test (p=0.05) and Egger's test (p=0.01) do not exclude the presence of publication bias in this case. Data on NODAT risk factors were less heterogeneous. This meta-analysis showed that age, polycystic kidney disease, i-mTOR and steroid therapy were associated with NODAT, whereas gender, calcineurin inhibitor use, and cadaveric kidney were not. There was no evidence of selection bias in any of the cases.

Conclusion. Risk factors for NODAT in kidney transplant recipients include older age, polycystic kidney disease, i-mTOR and steroid therapy, which initiate a state of insulin resistance. To reduce the risk of NODAT, the possibility of modifying immunosuppression regimens and the use of drugs that reduce insulin resistance and have a nephroprotective effect in RTRs should be considered. Therefore, randomized studies are needed to evaluate SGLT2 inhibitor in RTRs.

Introduction. Current strategies for treating osteoarthritis (OA) are based on a multimodal approach that includes pharmacological and non-pharmacological methods. Undenatured chicken collagen type II (NK2) is considered safe and effective for maintaining joint health and can be used alone and combined with drugs for OA treatment.

Aim. To further evaluate the efficacy of the combination of Artneo containing NK2 in patients with stage III knee OA compared with placebo in a multicenter, prospective, double-blind, placebo-controlled, randomized trial.

Materials and methods. The study included 212 patients from 12 centers in the Russian Federation, of whom 50 had radiological stage III knee OA: 41 (82.0%) females and 9 (18.0%) males aged 44 to 75. Using the interactive web response system (IWRS), the study population was randomized into two groups: Group 1 (Artneo group) included 28 patients receiving the drug 1 capsule once a day for 180 days, Group 2 (placebo group) included 22 patients receiving placebo with drug-matched presentation and the same regimen as in Group 1. The effectiveness of therapy was assessed by the change of pain using the Visual Analog Scale, the WOMAC index, KOOS, the EQ-5D quality of life questionnaire, and the need for non-steroidal anti-inflammatory drugs. All patients had a complete blood count, urinalysis, blood chemistry, and ultrasonic examination of the target knee joint.

Results. A prospective, double-blind, placebo-controlled, randomized trial demonstrated that Artneo containing NK2 was significantly superior to placebo in all studied parameters, improved all clinical manifestations of OA: reduced pain and stiffness, improved joint function and quality of life, and had a good safety profile.

Conclusion. Artneo showed high efficacy and safety in the general population of patients, including those with stage III knee OA.

The main causes of death in patients with heart failure (HF) are sudden cardiac death and decompensation of HF, especially with a low left ventricular ejection fraction. The prediction and prevention of risk factors for the development of these conditions are important goals both for guideline-directed medical therapy and for electrophysiological treatment methods. The article presents an overview of clinical studies devoted to the study of implantable cardioverter defibrillators in the prevention of sudden cardiac death, highlights the issues of monitoring the course of HF. Special attention is paid to multisensory monitoring in implantable devices equipped with a unique set of sensors for early diagnosis of the development of HF decompensation. It is expected that the practical use of such devices will reduce the number of exacerbations and hospitalizations for HF by detecting signs of threatening decompensation of blood circulation before the appearance of active symptoms, and as a result will reduce mortality in this category of patients.
