Abstract:

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.
