Relationship between the incidence of hyperuricemia and the clinical and pathological features in patients with renal glomerular disease / 中国综合临床

ABSTRACT

Objective To explore the effect of clinical and pathological features on the incidence of Hyperuricemia (HUA) in renal glomerular disease.Methods A retrospective analysis was applied to review the clinical and pathological date collected from 3547 patients with renal glomerular disease.These patients were diagnosed as renal glomerular disease by renal biopsy from January 2007 to December 2011.Results (1) HUA incidence was 21.8％ (773/3547) in all of the patients,in which the incidence in secondary glomerular disease 27.2％ (240/882) was much higher than that in primary glomerular disease 20.7％ (552/2665),and the difference was significant (x2 =153.642,P ＜ 0.05).In primary glomerular disease,HUA incidence was the lowest in membranous nephropathy 14.4％ (96/665),while HUA incidence in lupus nephritis (LN) 45.3％(110/243) was the highest and small blood vessel infammation kidney damage 34.7％ (17/49) was the second in secondary glomerular disease.(2) With the increasing of glomerulosclerosis index,tubulointerstitial score,renal vascular lesions score and the stage of chronic kidney disease,HUA incidence increased (x2 =17.798-298.216,P =0.000).(3)Logistic regression analysis showed that high tubulointerstitial score,glomerulosclerosis index and renal dysfunction,male,overweight or obese,hypertension and hypertriglyceridemia were risk factors for hyperuricemia (OR1.011-7.513,P ＜ 0.05).Conclusion The uric acid level is increased in nearly a quarter of patients with renal glomerular disease.Severe tubulointerstitial lesion,high glomerulosclerosis index,low glomerular filtration rate,male,overweight or obese,hypertension and hypertiglyceridemia were independent risk factors for HUA.
