Crohn’s disease is a chronic inflammatory condition of the gastrointestinal system, primarily impacting the distal ileum and colon. However, it can also affect any part of the digestive tract, from the mouth to the anus. This disorder is characterized by nonspecific inflammation, and its exact cause remains unknown. Crohn’s disease manifests as an idiopathic inflammatory process that can involve any segment of the gastrointestinal tract.
Epidemiology
Crohn’s disease can develop at any age, but it most commonly occurs between 25 and 30 years old. Both men and women are affected, with a slightly higher incidence among women. One-third of cases primarily involve the small bowel, often affecting the terminal ileum (ileitis). Approximately half of cases involve both the small bowel and colon, with the terminal ileum and adjacent proximal ascending colon being most commonly affected (ileocolitis). In 15-20% of cases, only the colon is affected.
Causes
The exact cause of Crohn’s disease remains unknown, but it is associated with several factors:
- Genetic Factors: Crohn’s disease can have a familial predisposition, with certain genes inherited from parents increasing the risk of developing the condition.
- Immune Disorders: Inflammation in Crohn’s disease may result from immune system dysfunction, leading it to mistakenly attack the normal flora of the gastrointestinal tract.
- Previous Infection: Prior infections may trigger an abnormal immune response, contributing to the development of Crohn’s disease.
- Smoking: Smokers with Crohn’s disease typically experience more severe symptoms compared to non-smokers.
Pathophysiology
Crohn’s disease can affect any part of the gastrointestinal (GI) tract, but it is most commonly observed in the terminal ileum, jejunum, and colon. The inflammation extends through all layers of the bowel wall (transmural). Typically, affected areas are not continuous, with segments of normal bowel interspersed between diseased portions. Ulcerations in Crohn’s disease are often deep and longitudinal, penetrating between islands of inflamed, edematous mucosa, resulting in the characteristic cobblestone appearance. Thickening of the bowel wall and narrowing of the lumen occur, leading to the development of strictures. Additionally, abscesses or fistula tracts may form, connecting with other loops of the bowel, skin, bladder, rectum, or vagina.
Clinical Manifestations
The manifestations of Crohn’s disease depend primarily on:
- The anatomical site of involvement
- The extent of the disease process
- The presence or absence of complications
Common symptoms include:
- Crampy abdominal pains caused by the intestines’ inability to transport gastrointestinal products through constricted lumens.
- Chronic diarrhea resulting from continuous irritating discharge emptied into the colon from swollen intestines, often accompanied by blood.
- Weight loss due to malabsorption and reduced food intake.
- Fever, indicating infection.
- Nausea and vomiting, which may signal the onset of small bowel obstruction.
- Constipation: While most patients experience diarrhea, some may suffer from constipation due to inflammation around the anus, making defecation difficult.
Management
Aims
- Control the inflammatory process.
- Relieve symptoms.
- Correct metabolic and nutritional problems and promote healing.
Diagnostic Studies
- Proctosigmoidoscopy: is typically the initial procedure to assess inflammation in the rectosigmoid area.
- Stool Occult Blood Test.
- Barium Enema: useful for identifying strictures and fissures.
- Small Bowel X-ray: Can reveal irregular mucosa, ulcerations, and stiffening.
- Sigmoidoscopy and colononoscopy: These procedures show patchy areas of inflammation.
- Biopsy: Obtained during sigmoidoscopy, it reveals granulomatous tissue.
- Blood tests: These may demonstrate an increased white blood cell count, a reduced erythrocyte sedimentation rate (ESR), and a decreased hemoglobin level.
Drug Therapy
While there is no specific therapy for Crohn’s disease, the following drugs may help manage symptoms:
- Corticosteroids (e.g., Prednisolone):
- Dosage: Prednisolone 5–60 mg daily orally, given as a single dose or in divided doses. The maximum daily dose is 250mg.
- Mode of Action: stimulates the synthesis of enzymes to decrease the inflammatory response.
- Side Effects: suppression of the immune system, resulting in lymphocytopenia.
- Aminosalicylates (e.g., Sulfasalazine):
- Dosage: Initial 3–4 g orally daily in divided doses, followed by a maintenance dose of 2g orally daily in divided doses.
- Mode of Action: Believed to be metabolized by intestinal flora in the colon, producing anti-inflammatory and antibacterial effects.
- Side Effects: reduced appetite, stomatitis, vertigo.
- Antibiotics (e.g., Metronidazole):
- Dosage: 200–400 mg orally three times daily for 7–10 days.
- Mode of Action: Bactericidal action by inhibiting bacterial DNA synthesis.
- Side Effects: dry mucous membranes, metallic taste.
- Anti-Diarrheals (e.g., Loperamide):
- Dosage: 4mg initially orally, then 2mg per loose stool. The maximum dose is 16mg in 24 hours.
- Mode of Action: Reduces intestinal motility and fluid secretion.
- Side Effects: constipation, abdominal pain, dry mouth, drowsiness.
- Analgesics (e.g., Paracetamol):
- Dosage: 500–1000 mg orally three times daily.
- Mode of Action: non-narcotic analgesic, antipyretic, and anti-inflammatory.
- Side Effects: Rare, but may include nausea, vomiting, and liver damage.
Other measures include:
- Vitamin supplements address the bowel’s inability to absorb nutrients effectively.
- In severe cases, patients may need to abstain from oral intake and receive parenteral feeds.
- Surgery may be necessary for severe cases, which may involve:
- Removing the affected portion of the bowel.
- Repairing fistulas.
- Draining abscesses.

- Treatment involves broad-spectrum antibiotics and, if malnourished, Total parental nutrition (TPN).
- Percutaneous drainage or surgery may be necessary for resolution.
- Obstruction:
- Small bowel obstruction can result from active inflammation or chronic fibrotic stricture formation, often exacerbated by dietary indiscretion.
- Fistulas:
- Enteromesenteric and enteroenteric fistulas are often asymptomatic, but may lead to complications such as abscess formation or bowel obstruction.
- Perianal Disease:
- Patients with fissures, fistulas, and skin tags may experience perianal discomfort.
- Conservative management includes sitz baths and the use of cotton pads to absorb drainage.
- Carcinoma:
- Patients with colonic Crohn’s disease are at increased risk of developing colon carcinoma.
- Some authorities recommend screening colonoscopies for early detection and intervention.
- Hemorrhage:
- Unlike ulcerative colitis, severe hemorrhage is uncommon in Crohn’s disease.
- Malabsorption:
- Malabsorption can arise from bacterial overgrowth, strictures, jejunal inflammation, or surgical resections.
- Management involves addressing underlying causes and optimizing nutritional support to mitigate complications.
