Circulating Elastin Fragments Are Not Affected by Hepatic, Renal and Hemodynamic Changes, But Reflect Survival in Cirrhosis with TIPS.

November 1, 2015

Dig Dis Sci

Abstract BACKGROUND AND AIMS Progressive fibrosis increases hepatic resistance and causes portal hypertension with complications. During progressive fibrosis remodeling and deposition of collagens and elastin occur. Elastin remodeling is crucially involved in fibrosis progression in animal models and human data. This study investigated the association of circulating elastin with the clinical outcome in cirrhotic patients […]

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 and urine markers of collagen degradation reflect renal fibrosis in experimental kidney diseases.

July 1, 2015

Nephrol Dial Transplant

Abstract BACKGROUND The extent of renal fibrosis in chronic kidney disease (CKD) is the best predictor for progression of most renal diseases. To date, no established biomarkers of renal fibrosis exist. METHODS We measured circulating and urinary-specific matrix metalloproteinase (MMP)-generated collagen type I and III degradation fragments (C1M and C3M) and an N-terminal propeptide of […]

Clinical Drug Development Using Dynamic Biomarkers to Enable Personalized Health Care in COPD.

July 1, 2015

Chest

Abstract Despite massive investments in the development of novel treatments for heterogeneous diseases such as COPD, the resources spent have only benefited a fraction of the population treated. Personalized health care to guide selection of a suitable patient population already in the clinical development of new compounds could offer a solution. This review discusses past […]

Suppressed bone remodeling in black bears conserves energy and bone mass during hibernation.

July 1, 2015

J Exp Biol

Abstract Decreased physical activity in mammals increases bone turnover and uncouples bone formation from bone resorption, leading to hypercalcemia, hypercalcuria, bone loss and increased fracture risk. Black bears, however, are physically inactive for up to 6 months annually during hibernation without losing cortical or trabecular bone mass. Bears have been shown to preserve trabecular bone volume […]

Accelerated extracellular matrix turnover during exacerbations of COPD.

June 11, 2015

Respir Res

Abstract BACKGROUND Exacerbations of chronic obstructive pulmonary disease (COPD) contribute significantly to disease progression. However, the effect on tissue structure and turnover is not well described. There is an urgent clinical need for biomarkers of disease activity associated with disease progression. Extracellular matrix (ECM) turnover reflects activity in tissues and consequently assessment of ECM turnover […]

Longitudinal change in collagen degradation biomarkers in idiopathic pulmonary fibrosis: an analysis from the prospective, multicentre PROFILE study.

June 1, 2015

Lancet Respir Med

Abstract BACKGROUND Idiopathic pulmonary fibrosis, a progressive and inevitably fatal disorder, has a highly variable clinical course. Biomarkers that reflect disease activity are urgently needed to inform patient management and for use as biomarkers of therapeutic response (theragnostic biomarkers) in clinical trials. We aimed to determine whether dynamic change in markers of extracellular matrix (ECM) […]

Pro-C5, a marker of true type V collagen formation and fibrillation, correlates with portal hypertension in patients with alcoholic cirrhosis.

May 1, 2015

Scand J Gastroenterol

Abstract BACKGROUND AND AIMS The hepatic venous pressure gradient (HVPG) is an important but invasive diagnostic and prognostic marker in cirrhotic patients. The aim of the study was to evaluate a novel biochemical plasma marker of true type V collagen formation (Pro-C5) for describing HVPG. METHODS Ninety-four patients mainly with alcoholic cirrhosis and fourteen liver-healthy […]

Guidelines for the standardization of preanalytic variables for blood-based biomarker studies in Alzheimer’s disease research.

May 1, 2015

Alzheimers Dement

Abstract The lack of readily available biomarkers is a significant hindrance toward progressing to effective therapeutic and preventative strategies for Alzheimer’s disease (AD). Blood-based biomarkers have potential to overcome access and cost barriers and greatly facilitate advanced neuroimaging and cerebrospinal fluid biomarker approaches. Despite the fact that preanalytical processing is the largest source of variability […]

Treatment of symptomatic knee osteoarthritis with oral salmon calcitonin: results from two phase 3 trials.

April 1, 2015

Osteoarthritis Cartilage

Abstract PURPOSE To evaluate the structure-modifying and symptom efficacy, as well as safety and tolerability of oral salmon calcitonin (sCT) formulated with a 5-CNAC carrier (a molecule based on Eligen(®) technology), in osteoarthritis (OA) patients with moderate to severe knee pain and joint structural damage classified as Kellgren and Lawrence (KL)2-3. METHODS AND DESIGN This […]
