Phenotypes of patients with asymptomatic hyperuricemia living in the Russian Federation

Aim. To identify the phenotypes of patients with asymptomatic hyperuricemia (HU) in the Russian Federation by analyzing demographic and clinical and laboratory parameters in outpatient practice.Material and methods. The data obtained in the framework of the non-interventional multicenter program “Assessment of epidemiological data on the detection of serum uric acid levels in patients with arterial hypertension, combined with metabolic syndrome, diabetes mellitus, and joint pain”, conducted in the Russian Federation, are presented. All study participants were examined according to the same single protocol.Results. Asymptomatic HU was detected in every 10th patient, predominantly in women, every 2nd person worked, 1/3 of the persons had a higher education, the majority had a family. Among comorbidities, the most common were arterial hypertension (AH), coronary heart disease, osteoarthritis. In HU, the risk of AH was elevated more than 2-fold, atrial fibrillation (AF) – 3-fold, osteoarthritis – 2-fold. A direct correlation of HU with age (p = 0.004; r = 0.17), female sex (p = 0.001; r = 0.76), retired status (p = 0.002; r = 0.19), AH (p = 0.018; r = 0.18), AF (p = 0.007; r = 0.16), osteoarthritis (p = 0.032; r = 0.13) was determined. Association of HU with age (odds ratio (OR) 1.04; 95 % confidence interval (CI) 1.02–1.07; p = 0.002), retired status (OR 2.59; 95 % CI 1.35–3.77; p = 0.002), AH (OR 2.27; 95 % CI 1.13–4.53; p = 0.021), AF (OR 3.07; 95 % CI 1.31–7.20; p = 0.010), osteoarthritis (OR 1.90; 95 % CI 1.05–3.43; p = 0.033) was confirmed.Conclusion. The phenotypes of patients with asymptomatic HU living in the Russian Federation were determined. An association of HU with a number of socio-demographic indicators, concomitant cardiovascular diseases, and osteoarthritis has been established.
