Abstract
Henoch–Schönlein purpura nephritis (HSPN) is a common secondary glomerulonephritis, and its prognosis mainly depends on the severity of renal impairment. To date, the significance of crescent lesions in adult-onset HSPN is still unclear. Therefore, the purpose of this research was to assess whether crescents could predict the renal outcomes in adult HSPN patients. A total of 188 adult patients with HSPN proven by renal biopsy were enrolled in this prospective study. Patients were divided into three groups based on the proportion of crescents: non-crescent group (C0, n = 110), crescent ≤ 25% group (C1, n = 50) and crescent > 25% group (C2, n = 28). The composited endpoint was defined as eGFR decreased > 50% of baseline level, reached end-stage renal disease and/or death. Among three groups, clinical pathological features, treatment regimens and renal outcomes were compared. During a mean follow-up of 26 months, 78 (42.5%) patients had crescent lesions. A total of ten (9.1%) patients in C0 group and five (17.9%) patients in C2 group reached the combined endpoint, but no patients in C1 group reached endpoint. Renal survival analysis indicated patients in C1 group tended to have the best renal outcome, while patients in C2 group had the poorest renal survival. Moreover, Cox regression analysis revealed crescents were not a predictor of poor developing to renal outcome after adjusting potential confounders [hazard ratio (HR) = 0.28, 95% confidence interval (CI) 0.07–1.18, P = 0.083]. Crescent formation is not necessarily a predictive factor of poor renal survival in adult HSPN patients who had small proportions of crescents (crescent ≤ 25%).
