Background: In Crohn's disease (CD), 10% to 40% of patients do not respond to anti-tumor necrosis factor-α (TNFα) treatment. Currently, there are no biomarkers with adequate sensitivity to separate responders from nonresponders at an early stage. Aim: The aim of this study was to investigated wheth...

Extracellular matrix (ECM) remodeling is a hallmark of the pathology of gastrointestinal disorders. Collagen type VI (COL6) is produced by fibroblasts, and the COL6 α3-chain has shown to be elevated in patients with ulcerative colitis (UC), Crohn's disease (CD) and colorectal cancer (CRC). Measuring...

Introduction: Extracellular matrix (ECM) remodeling of the intestinal tissue is important in inflammatory bowel disease (IBD) due to the extensive mucosal remodeling. There are still gaps in our knowledge as to how ECM remodeling is related to intestinal epithelium homeostasis and healing of the int...

OBJECTIVES: Portal hypertension in cirrhosis is associated with endothelial dysfunction, impaired wound healing, and decreased platelet count. Increased von Willebrand factor (VWF) formation has been suggested as a compensatory mechanism, but the role of VWF processing has not been directly assessed...

Background: Crohn’s disease (CD) is a chronic inflammatory condition of the intestinal tract resulting in severe intestinal tissue damage. The concept of mucosal healing has therefore gained significant interest as a therapeutic end point in the treatment of inflammatory bowel disease (IBD). Given t...

Altered extracellular matrix (ECM) remodeling is an important part of the pathology of gastrointestinal (GI) disorders. In the intestine, type XVI collagen (col-16) plays a role in pathogenesis by affecting ECM architecture and induce cell invasion. Measuring col-16 in serum may therefore have bioma...

BACKGROUND AND AIMS: Hernia formation is associated with alterations of collagen metabolism. Collagen synthesis and degradation cause a systemic release of products, which are measurable in serum. Recently, we reported changes in type V and IV collagen metabolisms in patients with inguinal and incis...

OBJECTIVE:Detecting significant fibrosis and cirrhosis remains important in treatment and follow-up of patients with chronic hepatitis C Infection (CHC). The aim of this study was to assess the ability of PRO-C3 to identify significant fibrosis (Ishak score ≥3) and cirrhosis (Ishak score ≥5) both as...

BACKGROUND:Increased protease activity is a key pathological feature of inflammatory bowel disease (IBD). However, the differences in extracellular matrix remodelling (ECM) in Crohn\u0027s disease (CD) and ulcerative colitis (UC) are not well described. An increased understanding of the inflammatory...

Background: Misbalances in extracellular matrix turnover are key factors in the development of stricturing (Montreal B2) and penetrating (Montreal B3) Crohn's disease. Aim: To determine whether serological markers for collagen formation and degradation could serve as biomarkers for complications of...

BACKGROUND: Throughout life, inguinal hernia develops in approximately every fourth man, some of whom develop multiple hernias. If patients at risk of developing multiple hernias could be identified by a serologic biomarker, treatment might be able to be tailored and improved. Evidence suggests that...
