Renal survival and risk factors in IgA nephropathy with crescents.

Abstract:

PURPOSE:The association between crescents and renal outcomes was inconsistent in a Chinese IgA nephropathy (IgAN) cohort, and limited research has investigated the prognosis of IgAN patients with crescents. METHODS:Between January 2008 and January 2013, 169 consecutive IgAN patients with crescents in the Xijing Hospital, who were matched to IgAN patients without crescents at a 1:1 ratio by sex, age, eGFR, and proteinuria were reviewed. Combined events were defined by either a ≥ 50% reduction in eGFR or ESRD. RESULTS:All patients were followed for a mean of 49.9 ± 26.0 months, and 41 (12.1%) patients had developed combined events. Five multivariate Cox regression models were created, and crescents was an independent risk factor for combined events. In model 5, crescents (HR = 2.216, 95% CI 1.040-4.345, P = 0.039) were notably associated with the risk of combined events after adjusting for age, sex, smoking, TA-P, persistent hematuria, and TA-MAP. Of the IgAN patients with crescents, 17.2% had developed combined events. In the baseline variables model, age, proteinuria, eGFR, E1, T1-T2, and RAAS had statistically significant associations with combined events in the multivariate Cox regression analyses. In the time varying variables model, TA-P, persistent hematuria, and TA-MAP were independent risk factors for combined events. CONCLUSION:We validated that the presence of crescents was an independent predictor of combined events in Chinese IgAN patients. Age, proteinuria, eGFR, E1, T1-T2, RAAS, TA-P, persistent hematuria, and TA-MAP were independent risk factors for combined events in IgAN patients with crescents.
