IBD Registry in a Sub-Saharan African Population

2019-12-03 23:27:55 | BioPortfolio


The investigators intend to establish a prospective registry of patients diagnosed with inflammatory bowel disease at Parirenyatwa hospital in Harare, Zimbabwe. The study will periodically collect data on disease phenotype, disease course, and clinical management, and will biobank stool specimens and germline DNA. One relative, and an individual from the same neighbourhood will be also be recruited for a nested case-control study into risk factors of inflammatory bowel disease in this population.


A prospective observational registry with a nested case-control study will be established at a gastrointestinal outpatient's clinic at a tertiary care hospital in Harare, Zimbabwe. The registry will recruit confirmed cases of inflammatory bowel disease from the clinic, other hospitals within and outside Harare, and from private practitioners. Two controls, a sibling or cousin, and an individual living in the same neighbourhood will also be recruited for each case. Demographic and clinical data will be obtained for all cases at baseline, after 6 months and annually thereafter. A questionnaire adapted from the International Organisation of IBD for risk factors of inflammatory bowel disease, and a food frequency questionnaire will be administered to all participants. Stool specimens, and germline DNA from peripheral blood will be biobanked in the Department of Medicine at the University of Zimbabwe. Preliminary data analysis will be carried out after at least 100 patients have been recruited. Descriptive statistics will be used to summarise data on demographic and phenotypic characteristics of inflammatory bowel disease, and incidence will be estimated for Harare. Risk factors for inflammatory bowel disease will be analysed using conditional logistic regression.

Medical and Biotech [MESH] Definitions

A species of Faecalbacterium, previously classified in the FUSOBACTERIUM genus, that is a major constituent of the GUT MICROBIOTA in healthy humans. It has anti-inflammatory activity and reduced numbers of this species occur in patients with INFLAMMATORY BOWEL DISEASES such as CROHN DISEASE.

Chronic, non-specific inflammation of the GASTROINTESTINAL TRACT. Etiology may be genetic or environmental. This term includes CROHN DISEASE and ULCERATIVE COLITIS.

A drug that is used in the management of inflammatory bowel diseases. Its activity is generally considered to lie in its metabolic breakdown product, 5-aminosalicylic acid (see MESALAMINE) released in the colon. (From Martindale, The Extra Pharmacopoeia, 30th ed, p907)

Surgical creation of an external opening into the ILEUM for fecal diversion or drainage. This replacement for the RECTUM is usually created in patients with severe INFLAMMATORY BOWEL DISEASES. Loop (continent) or tube (incontinent) procedures are most often employed.

A gamma-emitting radionuclide imaging agent used in the evaluation of regional cerebral blood flow and in non-invasive dynamic biodistribution studies and myocardial imaging. It has also been used to label leukocytes in the investigation of inflammatory bowel diseases.
