Abstract BACKGROUND The reference standard for detecting non-alcoholic steatohepatitis (NASH) and staging fibrosis-liver biopsy-is invasive and resource intensive. Non-invasive biomarkers are urgently needed, but few studies have compared these biomarkers in a single cohort. As part of the Liver Investigation: Testing Marker Utility in Steatohepatitis (LITMUS) project, we aimed to evaluate the diagnostic accuracy of […]

Abstract BACKGROUND The Lémann Index [LI] and the recently updated LI are tools for measuring structural bowel damage in adults with Crohn’s disease [CD] but have not been evaluated in children. We aimed to validate the updated LI in the prospective multicentre ImageKids study of paediatric CD. METHODS We included children with CD undergoing magnetic […]

Abstract PURPOSE To investigate acute changes in biochemical markers of bone and cartilage turnover in response to moderate intensity exercise with and without joint impact in healthy human subjects. METHODS A randomized, cross-over, exploratory, clinical study was conducted. Twenty healthy subjects with no history of joint trauma completed 30 min interventions of standardized moderate intensity cycling […]

Abstract In inflammatory bowel disease (IBD), the chronic inflammation deeply affects the intestinal extracellular matrix. The aim of this study was to investigate if remodeling of the intestinal basement membrane type VI collagen was associated with pathophysiological changes in Crohn’s disease (CD) and ulcerative colitis (UC). Serum from IBD patients (CD: n = 65; UC: n = 107; irritable […]

Abstract Renal fibrosis is a hallmark of chronic kidney disease (CKD) caused by an imbalance between formation and degradation of extracellular matrix proteins. We investigated the collagen turnover profile of 81 non-dialysis CKD stage 2-5 patients by measuring peptides reflecting formation and degradation of collagen type (COL) I, III, IV, and VI. Based on the […]

Abstract 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 Crohn’s disease. METHODS Serum biomarkers for type I, III, V and VI collagen formation […]

Abstract BACKGROUND Increased protease activity is a key pathological feature of inflammatory bowel disease (IBD). However, the differences in extracellular matrix remodelling (ECM) in Crohn’s disease (CD) and ulcerative colitis (UC) are not well described. An increased understanding of the inflammatory processes may provide optimized disease monitoring and diagnostics. We investigated the tissue remodelling in […]

Abstract The aim of the study was to assess the possible association between type II collagen turnover seromarkers and disease profile in patients with axial spondyloarthritis (SpA) and psoriatic arthritis (PsA). Outpatients with axial SpA (n = 110) or PsA (n = 101) underwent clinical examination including disease activity measures and HLA-B27 typing. The procollagen IIA N-terminal peptide (PIIANP) […]

Abstract BACKGROUND Renal fibrosis is the hallmark of progression to end-stage kidney disease. Non-invasive biomarkers of renal fibrosis could serve as specific end points in clinical trials and improve monitoring and stratification of patients with chronic kidney disease (CKD). To address this, we measured markers of collagen type III turnover in urine and serum of […]

Abstract Ankylosing spondylitis (AS) is characterized by gradual cementation of the vertebrae, a process that is described by excessive extracellular matrix remodeling. Specific matrix metalloproteinase (MMP)-derived collagen fragments are released to the circulation, and measurement of those might act as biomarkers of ankylosis. The aim of the study was to investigate the diagnostic value of […]
