Abstract:
Objective To analyze clinical and pathological data of IgA nephrology patients with microalbuminuria and investigate risk factors of its prognosis.Methods Clinical and pathological data of IgA nephrology patients with microalbuminuria were confirmed with renal biopsy and follow-up time with ＞ 6 months of trace was reviewed retrospectively;24-hour urine protein quantification ＞ 1 g, normal serum creatinine level when renal biopsy turned into abnormal level, or doubled serum creatinine level was defined as end point of follow-up.Renal survival was calculated with Kaplan-Meier survival analysis, and risk factors of progression were analyzed with univariate and multivariate Cox regression models.Results A total of 96 patients was followed up successfully, with an average follow-up time of (35.6 ± 22.7) months, and 34 cases (35.42％) entered the endpoint.The 12-, 24-, 36-, 48-, 60-, and 72-month renal survival rate was 97.92％, 92.71％, 86.45％ , 81.25％ , 71.88％, and 64.58％, respectively.Urine proteins, abnormal serum creatinine, Lee's Ⅲ～ V, renal interstitial fibrosis, glomerular sclerosis, and crescentic body were independent risk factors to affect prognosis of IgA nephropathy with microalbuminuria.Conclusions Early and active control of urinary microalbumin, and acute kidney injury caused by treatment of crescentic formation could slow the progress of IgA nephropathy.
