Hematological Indices and Fecal Calprotectin Predict Histological Remission in Ulcerative Colitis

Study Purpose

Investigators aimed at investigating the prediction ability of faecal calprotectin to predict mucosal healing and histological remission in ulcerative colitis patients receiving biological therapy Investigators aimed to evaluate the prediction ability of NLR, PLR and MLR to predict mucosal healing and histological remission in ulcerative colitis patients receiving biological therapy. Investigators evaluate the histological remission in ulcerative colitis patients receiving biological therapy in Assuit university hospital.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

Eligible Ages 18 Years - 55 Years

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.


Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Ulcerative Colitis
Additional Details

Ulcerative colitis (UC) is a chronic relapsing disease that involves the colorectal mucosa. Over the years, the therapeutic target has been upgraded from the resolution of symptoms to deep remission to prevent relapses and complications. The primary therapeutic target to be achieved in patients with UC is both clinical and endoscopic remission . The assessment of histological inflammation has emerged as a promising endpoint in UC . However, the link between histological disease activity and other measures of clinical disease activity is not yet well established . Some authors suggest that the presence of histological inflammation is a better predictor of future clinical relapse than endoscopic activity . Several studies showed that patients with residual microscopic active inflammation seem to be more prone to relapse when compared with patients with normal histology . Calprotectin is a 36-kDa calcium- and zinc-binding protein, which represents approximately 60% of soluble proteins of granulocyte cytoplasm . Fecal calprotectin (FC) is strongly correlated with both MES and Ulcerative Colitis Endoscopic Score (9, 10). In previous studies, FC was shown to be helpful in predicting sustained clinical remission and mucosal healing during anti-TNF treatment, particularly with IFX and ADA. However, no investigations have been performed to evaluate the predictive value of FC in terms of mucosal healing in a prospective cohort of patients with UC treated with biological therapy. Based on the above background, the aim of the present prospective study is to identify a reliable biomarker able to predict therapeutic effectiveness in UC . Ulcerative colitis (UC) is a chronic relapsing disease characterized by a neutrophil-mediated inflammation of the gut. Indeed, European Crohn and Colitis Organization guidelines have highlighted how the grade of neutrophilic infiltration is necessary for the diagnosis of this pathological condition and for the evaluation of histological activity. Thus, colonoscopy is necessary to collect mucosal biopsies and assess neutrophilic infiltration for the diagnosis and during follow-up to evaluate treatment response and predict long-term outcome, although histological healing is still debated. However, colonoscopy is an invasive, costly, and not always well-tolerated examination for patients. Apart from endoscopic interventions, disease severity can be also assessed using less-invasive biomarkers, including blood count. In these regard the investigators aimed to investigate the ability of prediction of hematological indices including (PLR, NLR and MLR) and fecal calprotectin to predict histological remission in ulcerative colitis patients receiving biological therapy .
