About this study

Official title: Differentiating Gut Tuberculosis and Crohn's Disease Via Magnetic Resonance Enterography

It is clinically challenging to differentiate Crohn's disease from gut tuberculosis especially in regions endemic of tuberculosis infection. The investigators plan to perform magnetic resonance enterography (MRE) who presented to our hospital in Shenzhen, China for new onset of lower gastrointestinal symptoms and ileocecal mucosal lesions of uncertain diagnosis as evidenced by the presence of inflammation, ulceration, strictures or nodules on colonoscopy. MRE findings will be independently interpreted by two radiologistsThe role of MRE in distinguishing gut tuberculosis from Crohn's disease will be determined.

Read the detailed description

The clinical presentation of gut tuberculosis and Crohn's disease is very similar. In areas endemic of tuberculosis infection, differentiating the two diseases remains difficult. Both disease entities can have similar clinical, endoscopic and histological findings. Yet, wrongly diagnosing gut tuberculosis as Crohn's disease can potentially result in disastrous outcomes, especially when anti-tumor necrosis factor therapy, an important therapeutic option for Crohn's disease, can result in fulminant reactivation of tuberculosis.

Magnetic resonance enterography (MRE) is emerging as a effective imaging modality in evaluating the disease status of Crohn's disease. MRE, unlike computed tomography, emits no radiation, and is suitable for repeated serial imaging in younger-age populations. Ulcerations, strictures, transmural enhancement and mesenteric combing of the small bowel can be clearly demonstrated via MRE in Crohn's disease. Yet, the utilization of MRE in diagnosing gut tuberculosis remains largely unexplored. Whether MRE can be used to differentiate gut tuberculosis from Crohn's disease remains unknown.

The investigators plan to consecutively recruit 150 patients presenting to our hospital in Shenzhen, China, for new onset of lower gastrointestinal symptoms and ileocecal mucosal lesions of uncertain diagnosis as evidenced by the presence of inflammation, ulceration, strictures or nodules on colonoscopy.All recruited participants will undergo MRE, to be performed on a 1.5 Tesla scanner (Magnetom Avanto, Siemens Healthcare, Erlangen, Germany). MRE findings will be independently interpreted by two radiologists with special expertise in abdominal MR imaging and blinded to the patients' clinical data. The relationship between radiological patterns and clinical, endoscopic and histological findings will be analyzed. The role of MRE in distinguishing gut tuberculosis from Crohn's disease will be determined.

Questions about this trial

What is this clinical trial studying?

An observational study of Crohn Disease and Intestinal Tuberculosis, run by The University of Hong Kong at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 17 Apr 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Small / large bowel transmural enhancement (time frame: During procedure). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Apr 2019; AzTrials last refreshed its copy on 1 Nov 2026.
