Introduction. One in 10 people with chronic kidney disease has gout, and an even higher percentage of people with gout have kidney disease [kidneyfund.org]. Objective of the study. Analysis of renal dysfunction in patients with gout in different age groups. Material and methods. 237 patients with gout (males 60 ± 8.0 years, females 63 ± 9.0 years). The patients were separated into two groups: the age of onset up to 59 years (group I, 91 people) and the age of onset after 60 years inclusive (group II, 146 people). Results. The renal function was mostly preserved in patients from group I – 51% had a level of glomerular filtration rate (GFR) corresponding to stage 2 of chronic kidney disease (CKD), stage 4 of CKD was determined in only 2 patients from group I. A pronounced decrease in kidney function was determined in group II – significantly more often there was stage 3 of CKD (16 (22%) in group I and 59 (46%) in group II, p = 0.001). In 12 participants in group II, GFR was below 29 ml/min/1.73 m2. Only in 6% of cases, a slight decrease in GFR was determined, which was 4 times lower than in group I. Conclusions. With increasing age, the frequency of risk factors for gout increases, especially for people with kidney damage: taking small doses of acetylsalicylic acid increases the risk from 6 to 40%, diuretics from 18 to 44%, alcohol consumption from 14 to 28%, hypertension from 44 to 78%, consumption of foods saturated with purine from 51 to 68%, overweightness and obesity from 58 to 76%.
