| Abstract: | Objective To evaluate the prevalence of hyperuricemia in patients with IgA nephropathy and find out the risk factors of hyperuricemia, including clinical and pathological characteristics. Methods A retrospective study enrolled 2566 adult patients, who admitted to the First Affiliated Hospital, Sun Yat-sen University from 1996.01 to 2012.12 and diagnosed with biopsy- proven IgA nephropathy was conducted. Results Among 2566 IgA nephropathy patients, the prevalence of hyperuricaemia was 36.6%. Prevalence of hyperuricaemia for CKD stage 1, 2, 3, 4, 5 was 16.2%, 37.4%, 66.4%, 87.7% and 76.4%, respectively. Adjusting Logistic regression analysis showed male gender, progressive stages of CKD, increased percentage of global glomerulosclerosis were independent risk factors of IgA nephropathy; male gender, progressive stage of CKD, increased level of cholesterol, increased percentage of global glomerulosclerosis were independent risk factors for CKD stage 1 - 2 patients; progressive stages of CKD and increased percentage of global glomerulosclerosis were independent risk factors for CKD stage 3 - 5 patients. Conclusion The prevalence of hyperuricemia in patients with IgA nephropathy was 36.6%, and identifying the risk factors associated with hyperuricaemia among different CKD stages of IgA nephropathy will be important to improve our understanding in intervention of this disease. |
