Abstract BACKGROUND & AIMS The role of antibody-mediated rejection (AMR) after liver transplantation (LT) remains controversial. Chronic AMR (cAMR) is often subclinical and may be missed without surveillance biopsies (svLbx). Transcriptome analyses have previously characterized molecular changes in T cell-mediated rejection (TCMR) after solid organ transplantation. We aimed to identify molecular signatures of cAMR after […]

Abstract OBJECTIVE The Foundation for National Institutes of Health (FNIH) OA Biomarkers Consortium aims to identify and qualify biomarkers to support drug development in knee osteoarthritis (OA). The PROGRESS OA study aims to externally validate prognostic biomarkers identified in the earlier Phase I study. DESIGN PROGRESS OA included data from the control arms of several […]

Abstract Psoriatic disease (PsD) is a complex, heterogeneous disease with unmet medical needs in terms of its diagnosis, management, and prognosis. The identification of biomarkers could improve the implementation of precision medicine in PsD, but to date, none of these biomarkers have been clinically validated. Biomarkers can support clinical trials in several ways, including (1) […]

Abstract Fibroblast-driven deposition of extracellular matrix, particularly type III collagen, is linked to poor outcomes in patients with liver fibrosis, fibrotic solid tumors such as hepatocellular carcinoma and pancreatic cancer as well as in patients with other fibrotic diseases. The pro-peptide of type III collagen (PRO-C3) serves as a serum biomarker of active collagen formation. […]

Abstract BACKGROUND Idiopathic pulmonary fibrosis (IPF) is characterised by damage to the epithelial layer, closely associated with the alveolar basement membrane (BM). We aimed to investigate how type IV collagen (COL4) in the BM changes with the progression of IPF. METHODS COL4 synthesis (PRO-C4) was detected in blood by the nordicPRO-C4 biomarker in patients with […]

Abstract BACKGROUND Endotrophin, a C-terminal pro-collagen type VIα3 fragment, has been shown to correlate with kidney interstitial fibrosis, kidney outcome measures and survival in various kidney diseases and kidney transplantation. In this study we investigated whether endotrophin is associated with fibrogenesis in T cell-mediated rejection (TCMR), allowing its use as a non-invasive biomarker. METHOD Plasma […]

Abstract BACKGROUND Non-invasive tests (NITs) are central to diagnosing and stratifying risk in steatotic liver disease (SLD). However, it remains unclear whether guideline-recommended NIT cut-offs apply to metabolic and alcohol-related liver disease (MetALD). AIM Evaluate the diagnostic and prognostic performance of five NITs in patients with MetALD. METHODS Single-centre study with 423 SLD patients, of […]

Abstract UNLABELLED Axial spondyloarthritis (axSpA), psoriatic arthritis (PsA), and systemic lupus erythematosus (SLE) are distinct rheumatological diseases with common molecular features. This study explored tissue-associated remodelling endotypes using blood-based biomarkers reflecting interstitial matrix and basement membrane remodelling. Baseline serum samples from radiographic axSpA (r-axSpA) (NCT02437162/NCT02438787) (= 66), PsA (NCT03158285) (= 267) and SLE (NCT02349061) (= 97) […]

Abstract The interaction among extracellular matrix (ECM) components (proteoglycans, elastin, laminins, collagens and metalloproteinases) is important for maintaining homeostasis of the skin. However, in chronic inflammatory diseases, tissue homeostasis is disrupted by having an uncontrolled remodelling of the ECM, resulting in an imbalance of its composition and functionality. In these pathologies, there is a dysregulation […]
