Impact of faecal calprotectin measurement on clinical decision-making in patients with Crohn's disease and ulcerative colitis.

ABSTRACT: BACKGROUND:Faecal calprotectin (FC) seems to be the best available biomarker for the detection of intestinal inflammation in patients with inflammatory bowel disease (IBD). The aim of this study is to clarify whether the measurement of FC has changed the number of ultrasound and endoscopic procedures, drug modifications, as well as FC re-measurements in IBD patients. METHODS:This retrospective study included 242 IBD patients with available FC values (case cohort) and 46 patients without an available FC value (control cohort). Clinical consequences such as carrying out abdominal ultrasound, endoscopy, drug modification or FC re-measurement at the next ambulatory presentation or during in-patient stay were collected. Statistical analysis was performed to determine the association between clinical decision-making and patient's characteristics, especially FC value. RESULTS:Overall, 192 (67%) clinical consequences were noted in both cohorts. In the case cohort 174 (91%) implications were noted compared to 18 (9%) in the control cohort (P < 0.001). In the case cohort, significantly more clinical consequences were detected in patients with Crohn's disease (CD) as well as in ulcerative colitis (UC) patients with a FC value > 250 mg/Kg than in patients with a value of ? 250 mg/Kg. In CD patients with high FC values significantly increased numbers of abdominal ultrasounds, endoscopies and FC re-measurements were noted. In UC patients with high FC values significantly increased numbers of abdominal ultrasounds, drug modifications and FC re-measurements were noted. CONCLUSION:Measurement of FC may alter physician's clinical decision-making in IBD patients beside other clinical and diagnostic parameters. Further prospective and survey studies are warranted to evaluate the influence of FC measurement in the daily clinical decision-making.

Project description:BackgroundUlcerative colitis (UC) is an inflammatory bowel disease (IBD) that is widely identified worldwide. This study aimed to investigate the phenotypic characterization and molecular typing of Clostridium difficile isolates among patients with UC at an inflammatory bowel disease clinic in Iran.MethodsIn this cross-sectional study, conducted from April 2015 to December 2015, 85 UC patients were assessed for C.difficile infection (CDI). C. difficile isolates were characterized based on their toxin profile and antimicrobial resistance pattern. Multi-locus sequence typing analysis (MLST) and PCR ribotyping were performed to define the genetic relationships between different lineages of toxigenic strains.ResultsThe prevalence of C. difficile isolates was 31.8% (27/85) in patients, of those 15 patients (17.6%) had CDI. Three different sequence types (STs) identified based on MLST among the toxigenic isolates, that is ST54 (33.3%), ST2 (53.3%), and ST37 (13.6%). C. difficile strains were divided into four different PCR-ribotypes (012, 014, 017 and IR1). The most common ribotype was 014 accounting for 48.3% (7/15) of all strains. The strains isolated during the first episode and recurrence of CDI usually belonged to PCR ribotype 014 (ST2). A high rate of CDI recurrence (14.1%, 12/85) experienced in UC patients. Colonization of the gastrointestinal tract with non-toxigenic C. difficile strains was frequent among patients with mild disease. All C. difficile isolates were susceptible to metronidazole, and vancomycin, 86 and 67% of isolates were resistant to clindamycin and erythromycin respectively. There was no correlation between the toxin type and antibiotic resistance (p > 0.05).ConclusionOverall CDI is rather prevalent in UC patients. All patients with CDI experienced moderate to severe disease and exposed to different antimicrobial and anti-inflammatory agents. Close monitoring and appropriate management including early detection and fast treatment of CDI will improve UC outcomes.

Project description:Background and aimsElevated fecal calprotectin (FC) levels have been reported to correlate with histological activity in patients with ulcerative colitis (UC). However, the accuracy of FC for evaluating histological activity of UC remains to be determined. The aim of this study was to determine the accuracy of FC for evaluating histological activity of UC, based on updated definitions.MethodsRelated studies were retrieved from the PubMed, Web of Science, Embase, and Cochrane databases. Adult participants diagnosed with UC were included when sufficient data could be extracted to calculate the accuracy of FC for evaluating histological activity. The primary outcome was histological response, and the secondary outcome was histological remission, defined according to a recently updated position paper of European Crohn's and Colitis Organization. Statistics were pooled using bivariate mixed-effects models. The area under the curve was estimated by summary receiver-operating characteristic curves.ResultsNine studies were included, from which 1039 patients were included for the analysis of histological response and 591 patients for histological remission. For the evaluation of histological response, the pooled sensitivity, specificity, and the area under the curve were 0.69 [95% confidence interval (CI): 0.52-0.82], 0.77 (95% CI: 0.63-0.87), and 0.80 (95% CI: 0.76-0.83), respectively. For the evaluation of histological remission, the corresponding estimates were 0.76 (95% CI: 0.71-0.81), 0.71 (95% CI: 0.62-0.78), and 0.79 (95% CI: 0.75-0.82), respectively. FC had a higher accuracy in studies using Nancy Index. For histological response, the cut-off values of FC ranged from 50 to 172 µg/g, and the sensitivity was higher in studies with FC cut-off values >100 µg/g (0.77 versus 0.65).ConclusionFC is a valuable biomarker for assessing histological activity in patients with UC. A cut-off value of 100-200 µg/g is more appropriate to spare patients from an unnecessary endoscopy and biopsy.
