Bowman's capsule rupture and the Oxford MEST-C score in adult patients with Immunoglobulin a vasculitis nephritis: a single center experience.

ABSTRACT:

Objective

Bowman's capsule rupture (BCR) is a glomerular pathological change, but it is still not well recognized in immunoglobulin A vasculitis nephritis (IgAV-N). The Oxford MEST-C score is a classification for IgA nephropathy; however, its clinical correlation and prognostic value in adult patients with IgAV-N are unclear.

Methods

A retrospective study of 145 adult patients with IgAV-N diagnosed by renal biopsy was conducted. Clinical manifestations, pathological changes and the prognosis of IgAV-N patients were compared depending on the presence or absence of BCR, International Study of Kidney Disease in Children (ISKDC) classification and MEST-C score. The primary endpoint events were end-stage renal disease, renal replacement therapy and all-cause death.

Results

In total, 51 of 145 (35.17%) patients with IgAV-N presented with BCR. Patients with BCR had more proteinuria, lower serum albumin, and more crescents. Compared with IgAV-N patients with crescents only, 51/100 patients with crescents combined with BCR had a higher proportion of crescents in all glomeruli (15.79% vs. 9.09%; p = 0.003). Patients with higher ISKDC grades had more severe clinical presentation, but it did not reflect the prognosis. However, the MEST-C score not only reflected clinical manifestations but also predicted prognosis (p < 0.05). BCR contributed to the effectiveness of the MEST-C score in predicting the prognosis of IgAV-N (C-index: 0.845 to 0.855).

Conclusions

BCR is associated with clinical manifestations and pathological changes in patients with IgAV-N. The ISKDC classification and MEST-C score are related to the patient's condition, but only the MEST-C score is correlated with the prognosis of patients with IgAV-N, while BCR can improve its predictive ability.

Project description:BackgroundIgAV, the most common systemic vasculitis in childhood, is an immunoglobulin A-associated immune complex-mediated disease and its underlying molecular mechanisms are not fully understood. This study attempted to identify differentially expressed genes (DEGs) and find dysregulated immune cell types in IgAV to find the underlying pathogenesis for IgAVN.MethodsGSE102114 datasets were obtained from the Gene Expression Omnibus (GEO) database to identify DEGs. Then, the protein-protein interaction (PPI) network of the DEGs was constructed using the STRING database. And key hub genes were identified by cytoHubba plug-in, performed functional enrichment analyses and followed by verification using PCR based on patient samples. Finally, the abundance of 24 immune cells were detected by Immune Cell Abundance Identifier (ImmuCellAI) to estimate the proportions and dysregulation of immune cell types within IgAVN.ResultA total of 4200 DEGs were screened in IgAVN patients compared to Health Donor, including 2004 upregulated and 2196 downregulated genes. Of the top 10 hub genes from PPI network, STAT1, TLR4, PTEN, UBB, HSPA8, ATP5B, UBA52, and CDC42 were verified significantly upregulated in more patients. Enrichment analyses indicated that hub genes were primarily enriched in Toll-like receptor (TLR) signaling pathway, nucleotide oligomerization domain (NOD)-like receptor signaling pathway, and Th17 signaling pathways. Moreover, we found a diversity of immune cells in IgAVN, consisting mainly of T cells. Finally, this study suggests that the overdifferentiation of Th2 cells, Th17 cells and Tfh cells may be involved in the occurrence and development of IgAVN.ConclusionWe screened out the key genes, pathways and maladjusted immune cells and associated with the pathogenesis of IgAVN. The unique characteristics of IgAV-infiltrating immune cell subsets were confirmed, providing new insights for future molecular targeted therapy and a direction for immunological research on IgAVN.
