Disrupted Redox Regulation and Inflammatory Response in Pyoderma Gangrenosum
Introduction. The pathophysiology of Pyoderma Gangrenosum (PG) involves altered innate and adaptive immunity, mutagenic and epigenetic changes, the autoinflammatory state, and the overexpression of cytokines.

| Summary: | Introduction. The pathophysiology of Pyoderma Gangrenosum (PG) involves altered innate and adaptive immunity, mutagenic and epigenetic changes, the autoinflammatory state, and the overexpression of cytokines. This study investigated the potential contribution of inflammation, redox signaling, and the immune system in the pathogenesis of PG. Materials and Methods. This case–control study included 36 patients with PG and 30 controls. We have determined the serum concentrations of acute phase proteins (C-reactive protein—CRP, alpha1 glycoprotein acid—AGPA, Albumin), interleukin-17A -IL-17A, β2 microglobulin-β2MG, reduced glutathione-GSH, oxidized glutathione- GSSG, the GSH/GSSG ratio, and hematological parameters (white blood cells-WBC, neutrophil-lymphocyte ratio-NLR, erythrocyte sedimentation rate-ESR) in patients with PG compared with controls. Furthermore, we have evaluated the variations in these markers before and after treatment in PG patients. Results. The serum concentrations of acute phase proteins (CRP, AGPA, and Albumin) and the IL-17A, β2MG, GSH, GSSG, and GSH/GSSG ratio were significantly different between the PG group and controls. Hematological parameters (WBC, NLR, and ESR), acute phase proteins (CRP, AGPA, and albumin), and IL-17A showed an exaggerated and persistent inflammatory response in patients with PG. In patients with PG associated with systemic diseases, the dysregulation of the biochemical events was more severe. Conclusions. The acute phase proteins, β2MG-MHC class I complex, and the GSH-GSSG system are unbalanced in PG. Our results could improve the diagnosis and our understanding of the pathogenic basis of PG. |
