The relationship between serum uric acid levels and glomerular ischemic lesions in patients with Immunoglobin A nephropathy-a analytical cross-sectional study

To investigate the relationship between serum uric acid levels and glomerular ischemic lesions in patients with immunoglobulin A nephropathy (IgAN) and the relevant risk factors. A total of 86 patients with IgAN and normal renal functions were divided into a hyperuricemia group and a normal serum uric acid group (control group). These patients were further divided into a glomerular ischemic lesions group and a non-glomerular ischemic lesions group (control group) based on the renal biopsy results. The relationship between serum uric acid levels and glomerular ischemic lesions was analysed. In patients with IgAN, the prevalence or occurrence of glomerular ischemic lesions was significantly higher in the hyperuricemia group compared with the normal serum uric acid group. Elevated serum uric acid levels are independently associated with glomerular ischemic disease. Hyperuricemia in patients with IgAN may lead to glomerular ischemic lesions, and lowering serum uric acid levels may delay the progression of IgAN.
