Study Description
Brief Summary:
The purpose of the study is to assess among others environmental and hygiene-related risk factors for microscopic colitis (MC), a common diarrheal disease.

Condition or disease Intervention/treatment
Microscopic Colitis Collagenous Colitis Lymphocytic Colitis Other: Whole saliva sample

Study Design

Study Type : Observational
Actual Enrollment : 487 participants
Observational Model: Case Control
Time Perspective: Retrospective
Official Title: Risk Factors for Microscopic Colitis: A Dutch Case-Control Study
Study Start Date : July 2014
Primary Completion Date : June 2016
Study Completion Date : July 2016
Groups and Cohorts

Group/Cohort Intervention/treatment
Microscopic Colitis
Group consists of subjects diagnosed with either collagenous of lymphocytic colitis between January 1, 2000 and December 31, 2012
Other: Whole saliva sample
Both case and control group will be approached to consider to give permission to sample saliva. This is not obligatory. Collected samples will be stored for future DNA research.
Healthy Controls
Control group consists of subjects with no history of microscopic colitis. Group is age and sex matched with the case-group
Other: Whole saliva sample
Both case and control group will be approached to consider to give permission to sample saliva. This is not obligatory. Collected samples will be stored for future DNA research.


Outcome Measures

Primary Outcome Measures :
  1. Assessment of environmental and hygiene-related risk factors for microscopic colitis [ Time Frame: Retrospective, between 2000 and 2012 ]
    Information about environmental and hygiene-related risk factors is obtained by a questionnaire, sent to subjects diagnosed with MC between 2000 and 2012


Secondary Outcome Measures :
  1. The difference between the CC and LC subpopulation regarding environmental, hygiene-related, and generally known risk factors [ Time Frame: Retrospective between 2000 and 2012 ]

    As generally known risk factors are considered: age, gender, medication, comorbidities and smoking.

    Information about risk factors is obtained by a questionnaire, sent to subjects diagnosed with MC between 2000 and 2012.
