Campylobacter Enteritis and Post-Infective Bowel Dysfunction (PI-BD): Role of Antibiotics and Microbiota (CERAMIC)

May 3, 2017 updated by: University of Nottingham

An Observational Study of the Role of Antibiotics, Inflammation and Changes in Microbiota in the Development of Post-infective Bowel Dysfunction Following Infection With Campylobacter Jejuni or Coli

The principal research objective is to determine the impact of antibiotic use on the risk of developing long term bowel symptoms after infection with the germ Campylobacter.

Study Overview

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

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

The secondary research objectives are:

  • To investigate how the particular strain of the Campylobacter germ that causes the infection, and the strength of the immune response that it stimulates in the bowel, affect the risk of long term bowel symptoms.
  • To explore what changes occur after Campylobacter infection in the bacteria that usually live in the large bowel (microbiota) and the chemicals that they produce (short-chain fatty acids) when they digest nutrients. We will look for differences between people who recover fully and people who have long term bowel symptoms.

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

18 years and older (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Adults in the Nottinghamshire area with no previous history of gastrointestinal disorder or surgical resection. Those who submit a stoo lsample from which Campylobacter spp. is cultured will be invited to take part.

Description

Inclusion Criteria:

  • Age ≥ 18
  • Clinical syndrome suggestive of intestinal infection, including symptoms such as new onset of abdominal pain, vomiting, diarrhoea, blood in stools, fever
  • Submission of stool sample to Nottingham University Hospitals Microbiology Laboratory for investigation of these symptoms
  • Campylobacter sp. cultured by selective media (standard clinical practice) from this stool sample

Exclusion Criteria:

  • Pregnancy declared by the candidate

  • History declared by the candidate of pre-existing gastrointestinal disorder, including but not limited to:

    • Inflammatory Bowel Disease
    • Coeliac Disease
    • Pancreatitis
    • Gallstone disease (biliary colic, cholecystitis)
    • Diverticulitis
    • Cancer of the gastrointestinal tract
    • Irritable Bowel Syndrome
  • Reported history of previous resection of any part of the gastrointestinal tract other than appendix or gallbladder
  • Intestinal stoma
  • Habitual use of opiate analgesics likely to alter bowel function e.g. morphine
  • Use of antibiotics in the preceding four weeks other than for treatment of index infection.
  • Use of purgative products/ high dose laxatives for bowel preparation in the four weeks prior to index infection.
  • Any condition where the candidate is likely to require a course of antibiotics in the next 3 months e.g. severe chronic respiratory disease, recurrent urinary tract infection, lower limb ulceration
  • Inability to complete the symptom questionnaires e.g. cognitive dysfunction limiting memory and understanding
  • Declared participation in any medical trials in the past 3 months
  • Anyone who in the opinion of the investigator is unlikely to be able to comply with the protocol e.g. cognitive dysfunction, chaotic lifestyle related to substance abuse

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Post-Campylobacter
Adults with symptoms of intestinal infection who submit a stool sample from which Campylobacter jejuni or coli is cultured

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
Measure Description
Time Frame
Yes/ no: Post-Infective bowel dysfunction (PI-BD)
Time Frame: 12 weeks after microbiological diagnosis of infection
This will be defined by response to the question "have your bowels returned to normal since your Campylobacter infection?"
12 weeks after microbiological diagnosis of infection

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Yes/ No: Post-Infective irritable bowel syndrome (PI-IBS)
Time Frame: 12 weeks after microbiological diagnosis of infection
Symptoms meeting Rome III criteria for Irritable Bowel Syndrome (other than 6 month duration)
12 weeks after microbiological diagnosis of infection

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.
