ABSTRACT

Objective To investigate urine levels of neutrophil gelatinase-associated lipocalin (NGAL) and kidney injury molecule 1(KIM-1), and its relevant influencing factors in young patients with hyperuricemia.Methods Sixty young subjects with hyperuricemia were randomly selected from physical check-up examination population (the hyperuricemic group), and 60 young subjects with normouricemia were randomly selected at the same time from physical check populationexamination (the control group).Urine NGAL and KIM-1, and other biochemical indicators were evaluated.Clinical data, iab tests, testing items and biochemical indicators between the two groups were analyzed by using t test or analysis of variance test.Regression analysis between the above indicators and urinary NGAL/creatinine (cr) and urine KIM-1/cr ratios were carried by using single regression analysis.Analyzed relevant Relevant influencing factors of urinary NGAL/cr and urine KIM-1/cr ratios were analyzed by using multiple linear regression.Results Urine NGAL/cr and urine KIM-1/cr ratios in the hyperuricemic group were higher than the control group (t=22.152 5, t=24.725 5, P＜0.01).Single regression analysis showed that serum uric acid level and urine NGAL/cr ratio, KIM-1/cr ratio was positively correlations correlated (r=0.63, P＜0.01;r=0.41, P＜0.01).Multiple linear regression analysises showed that serum uric acid,systolic blood pressure, HbA1c, serum creatinin and cholesterol level were the independent factors of urine NGAI/cr ratio.Age, blood uric acid level, systolic blood pressure, HbA1c and serum creatinin levels were independent factors of KIM-1/cr ratio.Conclusion There are high levels in of urine NGAL/cr and KIM-1/cr ratios in population with hyperuricemia.Hyperuricemia, high systolic pressure, diabetes mellitus, declined kidney function and hypercholesterolemia are independent factors of urine high NGAL/creatinin ratio.Oldage,hyperuricemia, high systolic pressure, diabetes mellitus and declined kidney function are independent factors of high urine KIM-1/cr ratio.
