We read with interest the article entitled “Biomarkers as Potential Treatment Targets in Inflammatory Bowel Disease: A Systemic Review,” which brings forward evidence that serum and faecal biomarkers do not possess adequate operational characteristics to make them stand-alone treatment targets in inflammatory bowel disease (IBD) but should be considered as important adjunctive measures to clini...

The aim was to examine the relationship of serum inflammatory markers to the level of single-breath diffusing capacity of carbon monoxide (TL,CO). A stratified sample (n = 1,121) of a Norwegian general population aged 18-73 yrs was examined. The inflammatory markers measured were calprotectin, a prominent protein in the cytosol fraction of neutrophil granulocytes, and alpha1-antitrypsin (alpha1...

Acute kidney injury (AKI) is associated with increased morbidity and mortality and is frequently encountered in coronary care units (CCUs). Its clinical presentation differs considerably from that of prerenal or intrinsic AKI. We used the biomarkers calprotectin and neutrophil gelatinase-associated lipocalin (NGAL) and compared their utility in predicting and differentiating intrinsic AKI. This...

INTRODUCTION Due to limitation of colonoscopy in assessing the entire bowel and patients' intolerance in inflammatory bowel disease (IBD), in the current study, we aimed to prospectively compare the accuracy of 99mTc(V)-dimercaptosuccinic acid (DMSA) and fecal calprotectin with ileocolonoscopy as new methods for localizing inflammations. METHODS Current prospective study conducted between 2012 ...

Fecal biomarkers have emerged as important tools to assess intestinal inflammation and enteropathy. The aim of this study was to investigate the correlations between the fecal markers, myeloperoxidase (MPO), lactoferrin (FL), calprotectin (FC) and lipocalin-2 (Lcn-2), and to compare differences by breastfeeding status as well as normalization by fecal protein or by fecal weight. Simultaneous, q...

BACKGROUND Calprotectin is a calcium-binding protein found in neutrophils. Increased levels are found in stools after mucosal damage due to inflammation, which causes influx of neutrophils into the gut lumen. MATERIAL AND METHOD This article is based on a review of the most pertinent publications found on Medline and our clinical experience from more than 10 years of using the test. RESULTS...

INTRODUCTION Monitoring the response to biological treatment in Crohn's disease (CD) is a very important element of the therapeutic optimisation. AIM To evaluate the usefulness of measuring calprotectin, lactoferrin, and myeloperoxidase in stool as markers of long-term clinical and endoscopic response to anti-tumour necrosis factor α (anti-TNF) treatment in CD. MATERIAL AND METHODS The stud...

BACKGROUND Appetite-modulating hormones ghrelin and leptin might be relevant to asthma with their pro-inflammatory effects, and calprotectin has been recognized as a promising marker of inflammation. The purpose of this study was to explore whether asthma, atopy and lung functions has a relation with serum levels of leptin, ghrelin and calprotectin as inflammatory markers in children. METHODS...

INTRODUCTION Biomarkers complementing clinical evaluations may help to reduce the length and size of proof-of-concept (PoC) trials aimed to obtain quick "go/no go" decisions in the clinical development of new treatments. We aimed to identify and validate serum biomarkers with a high sensitivity to change upon effective treatment in spondyloarthritis (SpA) PoC trials. METHODS The candidate bio...

Calprotectin (CP) is an antimicrobial protein produced and released by neutrophils that inhibits the growth of pathogenic microorganisms by sequestering essential metal nutrients in the extracellular space. In this work, spectroscopic and thermodynamic metal-binding studies are presented to delineate the zinc-binding properties of CP. Unique optical absorption and EPR spectroscopic signatures f...
