Abstract:
Objective To explore the correlation between serum uric acid levels and uric acid excretion indexes in children with primary nephrot?ic syndrome(PNS),and to reveal the prevalence of hyperuricemia and its possible causes in PNS. Methods The clinical data in 74 cases of pe?diatric PNS were retrospectively analyzed. These patients were grouped as hyperuric acid(HUA)or non?hyperuric acid(NUA),and their clinical features and laboratory findings were compared between two groups,including age,serum uric acid,serum creatinine,urea,cystatin C,triglycer?ide,cholesterol,albumin,creatinine clearance rate,24 hours urine uric acid,serum uric acid/serum creatinine,uric acid clearance,and the frac?tional excretion of uric acid and other indicators of differences. In addition ,a correlation analysis was carried out for the excretion of uric acid index. Results Several factors were lower in HUA group than that of NUA group ,such as the serum albumin and fractional excretion of uric acid(P1=0.034,P2=0.025);while the serum cystatin C and serum uric acid/serum creatinine ratio(P1=0.038,P2=0.001)was higher in HUA group. The uric acid excretion was negatively correlated with serum uric acid levels in all 74 children with PNS(r=-0.43,P=0.016),and the serum uric acid/creatinine ratio was positively correlated with serum uric acid(r=0.486,P=0.001). Conclusion Both the increase of blood uric acid production and excretion reduction were observed in children with PNS ,and the serum uric acid levels and renal tubular function is closely related.
