目的 探讨原发性IgA肾病(IgA nephropathy,IgAN)患者不同IgM沉积强度与肾小球超微结构病变及临床病理的关系。 方法 收集155例IgAN患者的临床病理资料。分为IgM阴性(51例)、轻度(89例)和中度及以上沉积(15例)3组。比较3组间肾小球超微特征性结构、临床指标、MEST-C评分差异并分析与IgM沉积强度的影响因素。 结果 与IgM阴性、IgM轻度沉积组相比,IgM中度及以上沉积组24 h尿蛋白水平、IgG沉积、肾小管萎缩/间质纤维化(T)评分、足突融合(foot process effacement,FPE)程度更高,血白蛋白水平、淋巴细胞计数更低(P < 0.05)。logistic结果显示FPE程度、T评分是IgM沉积强度的独立影响因素。 结论 IgM沉积强度与原发性IgAN患者FPE程度相关。FPE程度可协同临床病理评分更精准评估肾组织损伤及制定治疗方案。

Objective To investigate the correlations between IgM deposition levels,glomerular ultrastructural and clinicopathological features in primary IgA nephropathy(IgAN). Methods Data from 155 IgAN patients were categorized into three cohorts by IgM deposition levels. We assessed differences in glomerular ultrastructure, clinical indices, MEST-C scores, and factors influencing IgM deposition levels. Results The marked IgM cohort showed higher urinary protein, IgG deposition, and T scores, with reduced serum albumin and lymphocyte counts (P < 0.05). Logistic regression identified FPE and T score as independent factors for IgM deposition. Conclusions IgM deposition correlates with FPE severity in IgAN, suggesting its utility in assessing renal damage and guiding treatment strategies.
