Background. The risk of chronic kidney failure increases by 3–10 times with the steady increasing of uric acid level in the blood. It is known that the protein fractions is closely correlated with the level of uric acid. Objective. Microalbuminuria and microglobulinuria are predictors of kidney damage. The study involved 50 patients with gout who had never received preventive treatment of gouty nephropathy. We choosed Canephron N (Bionorica, Neumarkt, Germany) as a combined phytodrug with nephroprotective effect. All studied patients were men with obesity. Results. According to standard examination kidney damage haven’t been found, but laboratory tests on microproteinuria showed that the vast majority of patients have signs of subclinical gouty nephropathy. Conclusions. Canephron N in complex gout treatment helps to decrease uric acid level in the blood and increase its excretion.
