The impact of achieving remission in inflammatory bowel disease on plasma matrix -carboxyglutamate protein levels

Matrix -carboxyglutamic acid (MGLA) protein is a vitamin K dependent peptide which contributes to the immunomodulatory activity of mesenchymal stromal cells. There is a possible association between MGLA protein and inflammatory bowel disease (IBD) which is divided into Crohn’s disease (CD) and ulcerative colitis (UC). However, little is known about the clinical utility of MGLA protein in IBD patients. This study aimed to assess the impact of achieving remission on the serum MGLA protein levels in IBD patients. This prospective observational study included 60 newly diagnosed IBD patients. All patients were subjected to full clinical, laboratory, radiological, and histopathological assessment of IBD at baseline and six months after initiating treatment. Serum MGLA protein level was assessed using an enzyme-linked immunosorbent assay. There were 29 (48.3%) UC cases and 31 (51.67%) CD cases. We observed a significant decrease in serum MGLA protein levels after 6 months of treatment compared to pretreatment values in UC patients (120.490 ± 26.273 vs. 26.320 ± 17.378 nmol/L, p
