Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 11 to 18 years
  • All sexes
  • No healthy volunteers
  • Child, Adult

Who may be able to join

  • diagnosis of Crohn's disease or ulcerative colitis based on standard clinical, endoscopic, histologic and radiographic criteria (Porto criteria),
  • vaccination, as a part of the basic vaccination course, with five doses of diphtheria, tetanus and whole-cell pertussis vaccine, without booster dose after the age of 6,
  • written consent of the patient's legal guardians and the patient himself if he/she turns 16 years of age.

Who cannot join

  • serious exacerbation of inflammatory bowel disease defined as Paediatric Ulcerative Colitis Activity Index (PUCAI) > 65 points for patients with ulcerative colitis or Pediatric Crohn's Disease Activity Index (PCDAI) > 40 points for patients with Crohn's disease.

What is being measured

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

  1. Achieving seroprotective antibody concentration

    Antibody concentrations ≥0.1 IU/ml indicated protection against diphtheria, while levels ≥1.0 IU/ml were considered to ensure long-term protection.

    Measured: after 4-8 weeks

Secondary outcomes (3)
  1. Booster response

    Booster response was defined as a post-vaccination antibody concentration ≥0.4 IU/mL in initially seronegative subjects or as a fourfold increase of antibody concentration in initially seropositive ones.

    Measured: after 4-8 weeks

  2. Adverse effects

    Evaluation of adverse effects after vaccination.

    Measured: 3 days

  3. Inflammatory bowel disease exacerbation occurrence.

    Disease exacerbation assessed according to the Paediatric Ulcerative Colitis Activity Index (PUCAI) for patients with ulcerative colitis or Pediatric Crohn's Disease Activity Index (PCDAI) for patients with Crohn's disease.

    Measured: after 4-8 weeks

Questions about this trial

What is this clinical trial studying?

A study testing Diphtheria booster vaccination in people with Diphtheria and Inflammatory Bowel Diseases, run by Medical University of Warsaw.

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 3 inclusion and 1 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 26 Jun 2019. Status can change between updates, so confirm with the study contact before making plans.

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?

Achieving seroprotective antibody concentration (time frame: after 4-8 weeks). 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 NCT03998215, which also lists 1 linked publication.

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 26 Jun 2019; AzTrials last refreshed its copy on 7 Nov 2026.
