About this study

Official title: Prototype Study on Association Between Clinical, Laboratory and Thermographic Findings in Patients With Ulcerative Colitis

Ulcerative colitis represents a chronic condition occurring in relapsing and remitting fashion with uncertain outcome and requires lifelong treatment with considerable side effects. Diagnostic methods currently in use, clinical (endoscopy), imaging (CT, MR) or laboratory (C - reactive protein, fecal calprotectin) give an insight into disease activity but are possibly associated with significant discomfort for the patient and / or increased risk of irradiation and potential allergic reactions on contrast agents. For that reason there is a need for a noninvasive, biologically inert method for evaluation of disease activity in inflammatory bowel disease (IBD). Thermography possesses most of these characteristics. The aim of this study is to find potential link between pathological thermographic signs and endoscopic findings, serum C reactive protein (CRP) and calprotectin in the stool of patients with active and extensive ulcerative colitis.

Read the detailed description

Hypothesis: Documenting pathological thermographic signs in patients with extensive ulcerative colitis investigators will demonstrate pathological thermography criteria that correlate with standard inflammatory markers such as Mayo endoscopic subscore (ESS), CRP and calprotectin in patients with ulcerative colitis.

Aims: The aim of this study is to record abdominal thermographic images of patients with active ulcerative colitis (UC), to create interpretational thermographic criteria for these images and to compare them to abdominal infrared (IR) images of healthy volunteers. Furthermore, investigators intend to correlate these criteria with standard markers of inflammation such as CRP and calprotectin in patients with UC at the beginning of treatment and at the end.

Materials and methods: For the purpose of this work, 36 patients with extensive UC and 30 healthy individuals will be put throe thermographic imagining, have their stool tested for calprotectin and their blood for CRP. In addition, patients with UC will receive colonoscopy evaluations.

Expected scientific contribution: The results of this paper would give an additional contribution to existing tools for pursuing ulcerative colitis activity thus demonstrating the potential of thermography as a complementary method to standard methods in assessing disease activity. Establishing diagnostic criteria for this method would be a good addition to present clinical practice.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in abdominal surface temperatures in ulcerative colitis patients at 6 months

    Patients will be treated with mesalamin, corticosteroids or biologic therapy according to disease status during 6 months. Abdominal temperatures (maximal, minimum and average temperatures measured in Celsius) recorded by a thermographic camera will be acquired at enrollment and after 6 months of therapy.

    Measured: Six months

Secondary outcomes (5)
  1. Correlation of abdominal surface temperatures between ulcerative colitis patients and healthy volunteers.

    Comparison of abdominal surface temperatures (maximum, minimum and average) expressed in Celsius between patients with active ulcerative colitis and healthy controls and also between ulcerative colitis patients in remission and healthy controls.

    Measured: Baseline and after 6 months

  2. Correlation of abdominal surface temperature values with clinical markers of inflammation in ulcerative colitis.

    Maximal, minimal and average abdominal surface temperatures expressed in Celsius will be correlated to the Disease Activity Index (Mayo score). The Index assesses stool frequency (0-3 points, according to severity) rectal bleeding (0-3 points, according to severity), mucosal appearance at endoscopy (0-3 points, according to severity) and physician rating of disease activity (0-3 points, according to severity). All of the points make up a total sum to produce a score ranging from 0 to 12 points (no activity, to most severe activity). All correlations will be performed before and after 6 months of therapy.

    Measured: Baseline and after 6 months

  3. Correlation of abdominal surface temperature values with fecal markers of inflammation in ulcerative colitis.

    Maximal, minimal and average abdominal surface temperatures expressed in Celsius will be correlated to fecal calprotectin (µg/g) levels. All correlations will be performed before and after 6 months of therapy.

    Measured: Baseline and after 6 months

  4. Correlation of abdominal surface temperature values with serum markers of inflammation in ulcerative colitis.

    Maximal, minimal and average abdominal surface temperatures expressed in Celsius will be correlated to serum C - reactive protein (mg/L) levels. All correlations will be performed before and after 6 months of therapy.

    Measured: Baseline and after 6 months

  5. Correlation of abdominal surface temperature values with endoscopic markers of inflammation in ulcerative colitis.

    Maximal, minimal and average abdominal surface temperatures expressed in Celsius will be correlated to endoscopic parameters expressed as Mayo endoscopic subscore on a scale 0 - 3. [0 - normal or inactive disease; 1 - mild disease (erythema, decreased vascular pattern, mild friability); 2 - moderate disease (marked erythema, absent vascular pattern, friability, erosions); 3 - severe disease (spontaneous bleeding, ulceration)].

    All correlations will be performed before and after 6 months of therapy.

    Measured: Baseline and after 6 months

Questions about this trial

What is this clinical trial studying?

An observational study of Ulcerative Colitis, run by University Hospital Dubrava at 1 site in Croatia.

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 3 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 Jul 2018. 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 Croatia. 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?

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?

Change in abdominal surface temperatures in ulcerative colitis patients at 6 months (time frame: Six months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02149043, which also lists 3 linked publications.

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 Jul 2018.
