The PROSIT Cohort of Infliximab Biosimilar in IBD: A Prolonged Follow-up on the Effectiveness and Safety Across Italy.
2019
BACKGROUND We report a prospective, nationwide cohort evaluating the safety and effectiveness of CT-P13. METHODS A structured database was used to record serious adverse events (SAEs), clinical remission/response, inflammatory biomarkers (CRP and calprotectin), and endoscopic findings. RESULTS Eight hundred ten patients with inflammatory bowel disease (IBD) (452 Crohn's disease [CD]) were enrolled. Four hundred fifty-nine patients were naive to anti-TNFα (group A), 196 had a previous exposure (group B), and the remaining 155 were switched to CT-P13 (group C). All patients were included in the safety evaluation with a mean follow-up of 345 ± 215 days and a total number of 6501 infusions. One…
The Role of Laboratory Tests in Crohn's Disease.
2016
In the past, laboratory tests were considered of limited value in Crohn's disease (CD). In the era of biologics, laboratory tests have become essential to evaluate the inflammatory burden of the disease (C-reactive protein, fecal calprotectin) since symptoms-based scores are subjective, to predict the response to pharmacological options and the risk of relapse, to discriminate CD from ulcerative colitis, to select candidates to anti-tumor necrosis factors [screening tests looking for hepatitis B virus and hepatitis C virus status and latent tuberculosis], to assess the risk of adverse events (testing for thiopurine metabolites and thiopurine-methyltransferase activity), and to personalize a…
Salivary Stress/Immunological Markers in Crohn’s Disease and Ulcerative Colitis
2020
There is continuous and growing interest in research into new alternatives to standard biomarkers to detect and follow-up disease, reducing physical and psychological stress in patients needing regular and invasive medical examinations for the evaluation of pathologies, including inflammatory bowel diseases (IBD). Saliva is one of the most promising body fluids in the research of new biomarkers, thanks to the large number of molecules it contains. Many molecules present in saliva are often directly correlated to their concentration in the blood but may be affected by the condition of the oral cavity. This means that a careful selection of a specific biomarker is required for each pathology,…
Diagnostic Accuracy of Fecal Calprotectin Assay in Distinguishing Organic Causes of Chronic Diarrhea from Irritable Bowel Syndrome: A Prospective Stu…
2003
AbstractBackground: Fecal calprotectin (FC) has been proposed as a marker of inflammatory bowel disease (IBD), but few studies have evaluated its usefulness in patients with chronic diarrhea of various causes. We evaluated the diagnostic accuracy of a FC assay in identifying “organic” causes of chronic diarrhea in consecutive adults and children.Methods: We consecutively enrolled 70 adult patients (30 males, 40 females; median age, 35 years) and 50 children (20 males, 30 females; median age, 3.5 years) with chronic diarrhea of unknown origin. All patients underwent a complete work-up to identify the causes of chronic diarrhea. FC was measured by ELISA.Results: In adult patients, FC showed 6…
Fecal Calprotectin in Clinical Practice
2012
Background: Surrogate markers of colorectal inflammation are increasingly being recognized as important in differentiating organic from functional intestinal disorders. Fecal calprotectin (FC) can be easily measured in the stool, being released by leukocytes in inflammatory conditions. Aim: We evaluated FC as an index of inflammation in consecutive outpatients referred for colonoscopy for chronic, nonbloody diarrhea. Methods: Stool specimens of 346 outpatients with chronic, nonbloody diarrhea, referred for colonoscopy, were measured for FC levels. The proportion of patients correctly diagnosed with the test and the relationship with endoscopic and histologic findings were measured. Results:…
Relevance of dynamic studies with magnetic resonance enterography in Crohn's disease.
2020
A proper quantification of the inflammatory activity in Crohn's disease (CD) lesions is needed to establish the appropriate management for each patient. The aim of this study is to evaluate the inflammatory activity of affected segments in small bowel lesions using dynamic studies of magnetic resonance enterography (MRE) in patients undergoing surgery, and their correlation with the level of inflammation and histological fibrosis of the surgical piece.A prospective, consecutive, observational, clinical study was conducted that included all the patients with small bowel CD that underwent surgery in this center between March 2011 and September 2013. Diagnosis was established according to Lenn…
Correlation between fecal calprotectin and inflammation in the surgical specimen of Crohn's disease
2016
Background: An accurate assessment of the inflammatory activity is crucial to establish the most appropriate treatment in Crohn's disease (CD). The present study aimed to evaluate the utility of preoperative fecal calprotectin (FC) measurement in small bowel CD and its relationship with inflammatory activity in surgical pathology specimens. Methods: This was a prospective observational study including all the patients with small bowel CD operated on at our center between March 2011 and September 2013. Preoperative laboratory and stool tests were performed. A meticulous exploration of entire small bowel was performed during surgery, and the resected bowel (or a sample of whole intestinal wal…
Fecal assays detect hypersensitivity to cow's milk protein and gluten in adults with irritable bowel syndrome.
2011
Background & Aims Some patients with irritable bowel syndrome (IBS)-like symptoms suffer from food hypersensitivity (FH); their symptoms improve when they are placed on elimination diets. No assays identify patients with FH with satisfactory levels of sensitivity. We determined the frequency of FH among patients with symptoms of IBS and the ability of fecal assays for tryptase, eosinophil cationic protein (ECP), or calprotectin to diagnose FH. Methods The study included 160 patients with IBS, 40 patients with other gastrointestinal diseases, and 50 healthy individuals (controls). At the start of the study, patients completed a symptom severity questionnaire, fecal samples were assayed, and …
Plasma calprotectin levels in patients suffering from acute pancreatitis
2006
Calprotectin (Cal) concentration is elevated in acute inflammatory reactions and its increase in the plasma suggests a diagnostic potential for Cal assay. This study aimed (a) to evaluate the Cal plasma levels in patients suffering from acute pancreatitis (AP) and (b) to assess whether early assay of Cal plasma levels can be helpful in assessment of the severity of AP. Forty-six consecutive patients, median age 45 years, suffering from a first attack of AP were recruited at two medical centers. Data collected on admission included age, sex, delay between pain onset and admission, and Glasgow score. A severe outcome was defined according to the Atlanta criteria. AP was defined as edematous o…
