Abstract 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 whether early changes in the VICM (citrullinated and matrix […]

Abstract OBJECTIVES Clinical trials of new disease-modifying treatments for osteoarthritis should demonstrate a positive effect on a functional outcome or reduction in joint failure in order to be considered successful. Total joint replacement (TJR) surgery may be considered as joint failure, but great variation in the incidence of TJR complicates its use as a study […]

Abstract Osteoarthritis, rheumatoid arthritis, psoriatic arthritis, and ankylosing spondylitis, all have one clear common denominator; an altered turnover of bone. However, this may be more complex than a simple change in bone matrix and mineral turnover. While these diseases share a common tissue axis, their manifestations in the area of pathology are highly diverse, ranging […]

Abstract Different stimulants might induce different extracellular matrix profiles. It is essential to gain an understanding and quantification of these changes to allow for focused anti-fibrotic drug development. This study investigated the expression of extracellular matrix by dermal fibroblast mimicking fibrotic skin diseases as SSc using clinically validated biomarkers. Primary healthy human dermal fibroblasts were […]

Abstract BACKGROUND Tissue released blood-based biomarkers can provide insight into drug mode of action and response. To understand the changes in extracellular matrix turnover, we analyzed biomarkers associated with joint tissue turnover from a phase 3, randomized, placebo-controlled study of baricitinib in patients with active rheumatoid arthritis (RA). METHODS Serum biomarkers associated with synovial inflammation […]

Abstract OBJECTIVE Dysregulation of type I collagen metabolism has a great impact on human health. We have previously seen that matrix metalloproteinase-degraded type I collagen (C1M) is associated with early death and age-related pathologies. To dissect the biological impact of type I collagen dysregulation, we have performed a genome-wide screening of the genetic factors related […]

Abstract INTRODUCTION Anti-tumor necrosis factor (TNF) therapy is effective in inducing remission in Crohn’s disease in 60% of patients. No serological biomarkers are available, which can predict response to anti-TNF. We aimed to investigate serological markers of collagen turnover reflecting tissue inflammation as predictors of response to anti-TNF. METHODS In 2 retrospective observational cohorts, markers […]

Abstract OBJECTIVE Type II collagen is the most abundant protein of articular cartilage. The urinary cross-linked C-terminal telopeptide of type II collagen (uCTX-II) is a matrix metalloproteinase (MMP) cleaved fragment and may be the most well-validated biomarker in osteoarthritis. The aim was to develop a serological immunoassay of CTX-II (sCTX-II) and evaluated both sCTX-II and […]

Abstract Osteoarthritis (OA) is associated with cartilage breakdown, brought about by ADAMTS-5 mediated aggrecan degradation followed by MMP-derived aggrecan and type II collagen degradation. We investigated a novel anti-ADAMTS-5 inhibiting Nanobody (M6495) on cartilage turnover ex vivo. Bovine cartilage (BEX, = 4), human osteoarthritic – (HEX, = 8) and healthy-cartilage (hHEX, = 1) explants and […]
