Metabolites of type I, II, III, and IV collagen may serve as markers of disease activity in axial spondyloarthritis.

August 2, 2019

Sci Rep

Abstract Local inflammation in axial spondyloarthritis (axSpA) leads to the release of collagen metabolites from the disease-affected tissue. We investigated whether collagen metabolites were associated with disease activity and could distinguish non-radiographic(nr)-axSpA from ankylosing spondylitis (AS). A total of 193 axSpA patients (nr-axSpA, n = 121 and AS, n = 72) and asymptomatic controls (n = 100) were included. Serum levels […]

Association of metabolites reflecting type III and VI collagen formation with modified Rodnan skin score in systemic sclerosis – a cross-sectional study.

June 1, 2019

Biomarkers

Abstract The objective was to investigate blood-based biomarkers of type I (PRO-C1), III (PRO-C3) and VI (PRO-C6) collagen formation in systemic sclerosis (SSc) patients and examine their correlation to modified Rodnan skin score (mRSS). Limited (lSSc,  = 76) and diffuse SSc (dSSc,  = 41) fulfilling the ACR/EULAR 1980 and 2013 classification criteria for SSc and asymptomatic controls […]

Serological biomarkers detect active joint destruction and inflammation in patients with haemophilic arthropathy.

July 1, 2017

Haemophilia

Abstract INTRODUCTION Progressive arthropathy caused by recurrent joint bleeds is a severe complication in haemophilia. AIM We investigated whether biomarkers of cartilage and bone degradation, and inflammation were altered in haemophilia patients and whether these biomarkers could identify haemophilia patients with arthropathy. METHODS Serum from 35 haemophilia patients with varying degrees of arthropathy and 43 […]

Ulcerative colitis, Crohn’s disease, and irritable bowel syndrome have different profiles of extracellular matrix turnover, which also reflects disease activity in Crohn’s disease.

January 1, 2017

PLoS One

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 […]

Late-Life Risk Factors for All-Cause Dementia and Differential Dementia Diagnoses in Women: A Prospective Cohort Study.

March 1, 2016

Medicine (Baltimore)

Abstract Since the first evidence of a decline in dementia incidence was reported in 2011, the focus on modifiable risk factors has increased. The possibility of risk factor intervention as a prevention strategy has been widely discussed; however, further evidence in relation to risk factors is still needed. The Prospective Epidemiologic Risk Factor (PERF I) […]

Fragments of Citrullinated and MMP-degraded Vimentin and MMP-degraded Type III Collagen Are Novel Serological Biomarkers to Differentiate Crohn’s Disease from Ulcerative Colitis.

October 1, 2015

J Crohns Colitis

Abstract BACKGROUND AND AIMS A hallmark of inflammatory bowel disease [IBD] is chronic inflammation, which leads to excessive extracellular matrix [ECM] remodelling and release of specific protein fragments, called neoepitopes. We speculated that the biomarker profile panel for ulcerative colitis [UC] and Crohn’s disease [CD] represent a heterogeneous expression pattern, and may be applied as […]

Serum Fragments of Tau for the Differential Diagnosis of Alzheimer’s Disease.

January 1, 2015

Curr Alzheimer Res

Abstract Differential diagnosis of AD is still a challenge due to overlapping features with other types of dementia. Biomarkers for the differential diagnosis of AD can improve the diagnostic value of the disease and ensure an appropriate treatment of patients. The aim of this study was to evaluate the potential of two neo-epitope fragments of […]

Ankylosing spondylitis is characterized by an increased turnover of several different metalloproteinase-derived collagen species: a cross-sectional study.

November 1, 2012

Rheumatol Int

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 […]

Investigation of two novel biochemical markers of inflammation, matrix metalloproteinase and cathepsin generated fragments of C-reactive protein, in patients with ankylosing spondylitis.

June 1, 2012

Clin Exp Rheumatol

Abstract OBJECTIVES Ankylosing spondylitis (AS) is a chronic inflammation of the spine and the sacroiliac joints. Current markers of inflammation, such as C-reactive protein (CRP), are reflecting the production of an acute phase reactant rather than tissue specific inflammation, but the use of CRP as a diagnostic and prognostic marker for AS has not provided […]
