Increased remodeling of type XXII collagen is associated with an inflammatory phenotype in Crohn’s disease.

April 25, 2026

Sci Rep

Abstract In Crohn’s disease, extracellular matrix (ECM) dysfunction and loss of tissue integrity are key pathological features. Fibril-associated collagens with interrupted triple helices (FACIT) are known to regulate ECM assembly and mediate biophysical cues in their microenvironment but remain largely understudied. This study aimed to investigate a novel biomarker reflecting remodelling of the FACIT collagen […]

Circulating Endotrophin Predicts Myocardial Fibrosis Burden and Is Sensitive to Antifibrotic Therapy.

April 17, 2026

JACC Adv

Abstract BACKGROUND Novel collagen-derived circulating peptides, such as endotrophin, have been proposed as biomarkers of myocardial fibrosis. OBJECTIVES We aimed to determine the effect of pirfenidone, an antifibrotic agent, on circulating levels of these peptides, and their association with cardiovascular magnetic resonance extracellular volume (ECV). METHODS In the PIROUETTE (Pirfenidone in Patients with Heart Failure […]

Prognostic Performance of Phosphatidylethanol With Noninvasive Liver Fibrosis Tests in Alcohol-Related Liver Disease.

April 1, 2026

Gastroenterology

Abstract BACKGROUND & AIMS Alcohol is a key driver of liver-related mortality, and phosphatidylethanol (PEth) is a direct biomarker of alcohol intake. We investigated the prognostic performance of PEth with noninvasive liver fibrosis tests (NITs) for predicting hepatic decompensation in an alcohol-related liver disease (ALD) at-risk population. METHODS Prospective cohort study with 411 at risk […]

A Novel Fibroblast Activation Protein-Based Algorithm to Assess Fibrosis in Metabolic Dysfunction-Associated Steatotic Liver Disease.

April 1, 2026

J Gastroenterol Hepatol

Abstract BACKGROUND Noninvasive fibrosis testing is crucial for metabolic dysfunction-associated steatotic liver disease (MASLD) management. This study evaluated a marker of activated mesenchymal fibrogenic cells, circulating fibroblast activation protein (cFAP), in a novel diagnostic algorithm, FAP Index, for patients with MASLD. METHODS Two retrospective cohorts recruited from tertiary hepatology clinics were studied as training (n = 160) […]

Differential Effects of Antifibrotic Treatment on Outcome Prediction via Serial Matrix Metalloproteinase-Degraded C-Reactive Protein Neoepitope Levels in Idiopathic Pulmonary Fibrosis.

April 1, 2026

Chest

Abstract BACKGROUND Idiopathic pulmonary fibrosis (IPF) is characterized by an increase in proteolytic enzymes, including matrix metalloproteinases that degrade the extracellular matrix and markers of localized inflammation. Protein fragments (neoepitopes) are detectable in the circulation. RESEARCH QUESTION Can short-term trajectories of neoepitopes after initiation of antifibrotic treatment predict therapy-related outcomes, including mortality, in patients with […]

Collagen protein supplementation does not modulate biomarkers of bone metabolism following total hip arthroplasty: a randomized, double-blind, placebo-controlled trial.

March 27, 2026

Clin Nutr ESPEN

Abstract BACKGROUND & AIMS Healing after total hip arthroplasty (THA) involves remodelling of collagenous tissues, such as bone. While collagen protein supplementation has been suggested to modulate bone metabolism, the effects following THA are yet to be investigated. Therefore, we aimed to characterize changes in biomarkers of bone metabolism following THA and to assess the […]
