OBJECTIVE Current methods do not predict the acute renal allograft injury immediately after kidney transplantation. We evaluated the diagnostic performance of urinary calprotectin for predicting immediate posttransplant allograft injury. METHODS In a multicenter, prospective-cohort study of 144 incipient renal transplant recipients, we postoperatively measured urinary calprotectin using an en...

OBJECTIVES Calprotectin is released from activated leukocytes and calprotectin can thus be used as a marker for leukocyte activation. Faeces calprotectin is not only used as a marker for inflammatory bowel disease but can also be used to detect leukocyte activation in other body fluids. The aim of the present study was to study serum calprotectin levels in non-infected elderly individuals to es...

Background. Pediatric inflammatory bowel disease (IBD) is on the rise worldwide. Endoscopies are necessary for IBD assessment but are invasive, expensive, and inconvenient. Recently, fecal calprotectin (FCal) was proposed as a noninvasive and specific marker of gut inflammation. We evaluated the analytical performance of three FCal assays and their clinical performance in predicting relapse in ...

BACKGROUND Fecal calprotectin has been proposed as a non-invasive marker of intestinal inflammation in inflammatory bowel disease in adults and children. Fecal calprotectin levels have been reported to be much higher in both healthy full-term and preterm infants than in children and adults. OBJECTIVE To determine the time course of fecal calprotectin (f-calprotectin) excretion in preterm infa...

PURPOSE Among the many factors associated with acute intestinal mucosal infection, numerous studies have proposed the usefulness of fecal calprotectin. The aim of this study was to evaluate the usefulness of fecal calprotectin in the diagnosis of necrotizing enterocolitis (NEC). METHODS We collected 154 stool samples from 16 very low birth weight and premature newborns at the Konyang Universi...

The objective of this study is to valuate two biomarkers that may guide nutritional assessment during follow up after intestinal transplantation. We performed a retrospective study on prospectively collected data of insulin-like growth factor-1 (IGF-1) and effluent calprotectin in patients undergoing intestinal transplantation. Optimal nutritional status (ONS) was defined by using the Malnutrit...

PURPOSE Gastroenterologists have been seeking reliable noninvasive indices of inflammatory and malignant bowel disease. This prospective study was to assess the value of fecal calprotectin in predicting abnormal histologic findings in patients undergoing colonoscopy. METHODS Stool specimens supplied before colonoscopy by 72 consecutive patients were measured for calprotectin levels, and the f...

INTRODUCTION Microscopic bowel inflammation is present in up to 50% of patients with spondyloarthritis (SpA) and is associated with more severe disease. Currently no reliable biomarkers exist to identify patients at risk. Calprotectin is a sensitive marker of neutrophilic inflammation, measurable in serum and stool. OBJECTIVES To assess whether serum and faecal calprotectin in addition to C-r...

BACKGROUND Plasma calprotectin is a potential biomarker of cardiovascular disease (CVD), insulin resistance (IR), and obesity. We examined the relationship between plasma calprotectin concentrations, CVD manifestations and the metabolic syndrome (MetS) in patients with type 2 diabetes mellitus (T2DM) in order to evaluate plasma calprotectin as a risk assessor of CVD in diabetic patients without...

Introduction Calprotectin (S100A8/A9) is an example of a damage associated molecular pattern and a TLR4 ligand. It is expressed in neutrophils, monocytes and early infiltrating macrophages. Calprotectin, once secreted, has a number of proinflammatory effects on activated endothelium and on phagocytes and reflects activation of the innate immune system. Calprotectin has been demonstrated to be s...
