In recent decades, the prevalence of hyperuricemia (HU) is increasing worldwide; the role of uric acid (UA) in the genesis of various metabolic disorders, cardiovascular diseases, and kidney disease is being discussed. There are very few investigations of the rate of HU and its role in the development of diseases in certain social groups, including in professional athletes.Objective:to estimate the prevalence of HU and its role in the genesis of various pathological conditions and metabolic disturbances in professional athletes.Patients and methods.A retrospective comparative one-stage study was conducted, for which 2148 athletes who met inclusion criteria were selected and examined in the Federal Research and Clinical Center for Sports Medicine and Rehabilitation, Federal Biomedical Agency, in 2015. A control group consisted of 99 ageand sex-matched healthy volunteers examined at the V.A. Nasonova Research Institute of Rheumatology in 2017. The analysis included a comparison of the rate of HU and other examined parameters in professional athletes and healthy volunteers. The examined parameters were separately compared in athletes with/without HU, followed by statistical processing of results.Results.HU was detected in 306 (14.2%) of the 2148 athletes, more often in men (n=253 (20%) than in women (n=53 (6%); (p<0.001). The rate of HU in the athletes was comparable with that in the healthy population (12.1%). The athletes with HU (n=306) compared with the other athletes (n=1842) had the following statistically higher indicators: the mean serum levels of creatinine, triglycerides, aspartate aminotransferase, alanine aminotransferase, gamma-glutamyltranspeptidase, creatinine phosphokinase, and myoglobin, glomerular filtration rate, and body mass index (BMI) (p<0.00001 for all cases).Conclusion.HU is detected quite often in professional athletes (14.2%), which is comparable with the indicators seen in healthy volunteers (12.1%). The high prevalence of HU and its association with indicators reflecting kidney function, lipid metabolic disturbances, and BMI necessitate further investigations aimed at searching the causes of HU and methods of its prevention and treatment in professional athletes.
Objective: analysis of the effectiveness of combating doping in sports in the process of medical and biological support of athletes forming the national teams of the Russian Federation, and determining its ways.Materials and methods: based on the reports of anti-doping organizations for 2017–2022, sociological studies of the prevalence of doping in sports and therapeutic use structures, a retrospective analysis of the dynamics of the main indicators reflecting the directions of various doping encounters was carried out.Results: a significant discrepancy was revealed between the assessment of the prevalence of anti-doping rule violations based on the results of sociological surveys and the results of laboratory anti-doping studies.A significant positive dynamic of approval of therapeutic use exemptions, which allowed doubling the share of positive decisions of anti-doping organizations is shown.The main directions of improving anti-doping work in the process of carrying out medical and biological support measures are determined.
Objective: the main topics of the doctors’ questions were the preparation of medical documents for a TUE application, the determination of the antidoping status of various substances and methods, as well as the use of dietary supplements in sports.Materials and methods: an analysis was carried out of more than 400 appeals of doctors providing medical assistance to athletes of various levels on the issues of countering doping in sports. The aim of the work was to identify ways to improve educational and informational activities aimed at improving the quality of medical documents for TUE applications.Results: the need for continuous work to improve the level of doctors’ knowledge in countering doping in sports was confirmed, including clarification of the procedure for using documents from antidoping organizations, the need to use TUE guidelines for physicians and the specifics of prescribing substances prohibited only during the competitive period.
