Assessment of Capsule Endoscopy Scoring Index (CESI), Harvey-Bradshaw Index (HBI) and Biological Markers in Small Bowel Crohn's Disease (SBCD)

Assessment of Capsule Endoscopy Scoring Index, Clinical Disease Activity and Biological Markers in Small Bowel Crohn's Disease

Background: Small bowel Crohn's disease (SBCD) is a chronic relapsing disease, and clinical presentation can vary considerably. Patients are frequently assessed by capsule endoscopy (CE), which enables direct visualization of small bowel mucosal abnormalities; however, the correlations between CE scoring index (CESI), biological markers, and disease activity indices remain undefined.

Methods: A prospective study was conducted between October 2008 and February 2011 on 58 established SBCD patients and suspected patients who received a definitive SBCD diagnosis during study. Patients underwent complete CE, and were scored according to the CESI (inactive, <135; mild inflammation, 135-790; moderate-severe inflammation, >790) and Harvey-Bradshaw index (HBI). Statistical correlation between CESI, HBI, C-reactive protein (CRP), serum albumin, and hemoglobin was assessed. At follow-up (~9 months), 11 of the patients underwent CE with scoring for CESI, HBI, and CRP.

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

Parameters CESI To calculate the CESI, the small bowel was divided into three tertiles. The degree of disease involvement in each tertile was determined by assessing three parameters: villous edema, ulceration, and stenosis. Endoscopic remission was defined as CESI of <135. Mild inflammation was defined as CESI of 135-790, and moderate-severe inflammation as ≥790.

HBI HBI was used to assess the clinical disease activity. Patients with HBI >4 were considered to have clinically active disease.[7]

Blood analysis At the time of CE, patients provided a blood sample for measurement of hemoglobin, serum CRP, and albumin. Hemoglobin (normal ranges: women, 120-160 g/L and men, 140-180 g/L), albumin (normal range: 35-55 g/L), and CRP (upper limit of normal: <8 mg/L) were determined by routine laboratory tests.

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

13 years to 76 years (Child, Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Probability Sample

Study Population

All patients underwent CE examination (described below), and only those patients for whom complete CE examination (in which the capsule reached the cecum within the CE test time) was achieved were retained for study.

Description

Inclusion Criteria:

  • patients with known SBCD or newly diagnosed SBCD
  • those patients for whom complete CE examination (in which the capsule
  • reached the cecum within the CE test time) was achieved were retained for study

Exclusion Criteria:

  • incomplete CE examination
  • infectious enterocolitis
  • symptoms related to perianal penetrating disease
  • gastrointestinal cancer
  • ulcerative colitis
  • indeterminate colitis
  • history of extensive small bowel resection
  • known CD of the upper gastrointestinal tract or colon
  • intake of non-steroidal anti-inflammatory drugs (NSAIDs) (more than two tablets per week)
  • pregnancy

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Weak, but significant, correlations were found between CESI and HBI (r=0.4, p<0.01).
Time Frame: 2012.06
2012.06
The correlation between CESI and CRP was moderate (r=0.58, p<0.01).
Time Frame: 2012.07
2012.07
The median CRP value was significantly higher in patients with moderate-severe CESI, compared to the mild group (22.60±16.79 mg/L vs. 11.88±8.39 mg/L, p<0.01).
Time Frame: 2012.08
2012.08
Changes between baseline and follow-up CESI failed to correlate with the delta-HBI or delta-CRP (both, p>0.05).
Time Frame: 2012.09

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
