Ethnicity: High risk in Caucasians, and notably people of Eastern European (Ashkenazi) Jewish descent
Crohn’s disease (CD) is a type of inflammatory bowel disease (IBD) that is characterised by chronic inflammation of the gastrointestinal (GI) tract.2
- Unlike ulcerative colitis (UC), CD can affect the whole length of the gastrointestinal tract
- The most common area affected is the end portion of the small intestine (ileum)2
- Abdominal pain
- Rectal bleeding
- Weight loss
- Signs of malnutrition
Both UC and CD can increase the risk of colorectal cancer (CRC):4
- The risk is related to the duration of the disease
- Risk is also linked to the extent (i.e. the length of the colon involved) and the severity of the disease
Several factors may contribute to the risk of developing IBD, including:4,5
Genetics: Family history – 5–20% of patients have a first-degree relative with IBD
Habitat: Those living in urban areas and industrial nations may be more likely to develop UC or CD than those in more rural areas
Diagnosis may involve a combination of the following tests and examinations.2
May be performed to check for anaemia, which may indicate bleeding in the intestines. Blood tests may also uncover a high white blood cell count, which is a sign of inflammation somewhere in the body.2
By testing a stool (faecal) sample, clinicians can tell if there is bleeding or infection in the intestines. Stool tests are commonly done to rule out other diseases of the GI tract, such as cancer.2
Magnetic resonance imaging (MRI) or computed tomography (CT) may be used to examine the small intestine in people with suspected Crohn's disease in order to identify visible abnormalities in the gut.2
Flexible sigmoidoscopy and colonoscopy
These tests are performed using a long, flexible tube that has a small video camera on the end. A doctor can carefully examine the rectum, colon and small intestine for inflammation, bleeding, or ulcers, or may perform a biopsy. The tissue taken during a biopsy can be analysed microscopically to confirm a diagnosis.2
The management of IBD may involve medications, surgery, and nutritional support.
The general categories of drugs used in the treatment of CD:2
- Antibiotics (e.g. ampicillin) that commonly treat and prevent bacterial
- Steroids (e.g. prednisolone) that reduce gut inflammationinfections in the gut
- Immunomodulators (e.g. azathioprine or 6-mercaptopurine) that dampen the body’s immune responses that contribute to inflammation in the gut
- Biologic therapies (e.g. infliximab, adalimumab, vedolizumab or ustekinumab) that reduce gut inflammation
Surgery may be necessary to relieve symptoms when people do not respond to medications or if complications occur. Removal of specific sections of the small intestine, colon or rectum may be necessary.2
Diet and Nutrition
Proper nutrition is also a part of managing both UC and CD, and it is important that patients follow a nutritious diet and avoid foods that may worsen their symptoms.2
