Synonyms and keywords: autoimmune colitis, ulcerative colitis, Crohn's colitis, infectious colitis, pseudomembranous colitis, enterohemorrhagic colitis, microscopic colitis, lymphocytic colitis, collagenous colitis, diversion colitis, chemical colitis, ischemic colitis, indeterminate colitis, atypical colitis, fulminant colitis, immune mediated colitis, immune colitis

Overview

Colitis the inflammation of the colon, that can be either acute or chronic.

Classification

Classes of Colitis	Disorders
Autoimmune colitis	Ulcerative colitis Crohn's colitis
Infectious colitis	Pseudomembranous colitis (Clostridium difficile) Enterohemorrhagic colitis (Shigella dysenteriae or Shigatoxigenic group of Escherichia coli (STEC)) Parasite infection (Entamoeba histolytica)
Microscopic colitis	Lymphocytic colitis Collagenous colitis
Iatrogenic	Diversion colitis Chemical colitis
Vacular disease	Ischemic colitis
Unclassifiable	Indeterminate colitis (features of both Crohn's disease and ulcerative colitis) Atypical colitis

Notes:

• Fulminant colitis is any colitis with a rapid downhill clinical course; in addition to the diarrhea, fever, and anemia seen in colitis, the patient has severe abdominal pain and presents a clinical picture similar to that of septicemia, where shock is present.
• Irritable bowel syndrome, a separate disease, has been called spastic colitis or spastic colon. This name causes confusion, since colitis is not a feature of irritable bowel syndrome.
• Immune mediated colitis is the experimental name in animal studies of ulcerative colitis. It is a synonym of ulcerative colitis, but it should not be used as a synonym when referring to ulcerative colitis.

Diagnosis

Symptoms

• Diarrhea
• Abdominal pain
• Rectal bleeding

Physical Examination

• Abdominal tenderness
• Fever
• Hypotension and tachycardia

Diagnostic Tests

Colitis is associated with the following findings:

• Swelling of the colon tissue
• Bleeding
• Erythema (redness) of the surface of the colon
• Ulcerations of the colon

Common tests which reveal these signs include:

• X-rays of the colon
• Testing the stool for blood and pus
• Sigmoidoscopy
• Colonoscopy

Additional tests include stool cultures and blood tests, including blood chemistry tests. A high erythrocyte sedimentation rate (ESR) is one typical finding in acute exacerbations of colitis.

Treatment

Medical Therapy

Treatment of colitis may include the administration of antibiotics and general anti-inflammatory medications such as Mesalamine or its derivatives, steroids, or one of a number of other drugs that ameliorate inflammation.

Changes in diet can be effective at treating the symptoms of colitis and easing the side effects. These can include reducing the intake of carbohydrates, lactose products, soft drinks, and caffeine. This approach has been championed by Elaine Gottschall.

Hygienic and naturopathic doctors have taken the diet approach further, attributing bowel inflammation to toxemia stemming from high-protein, fatty diets and other dietary irritants. Changing to a low-fat, minimally-processed, whole-foods diet per the Natural Hygiene self-healing system has been effective in eliminating symptoms and rebuilding health. Dr. Zarin Azar, MD,, is one advocate of this healing system.

Infliximab (or REMICADE) - a drug originally produced to treat Rheumatoid Arthritis - has recently been approved for the treatment of Colitis where traditional treatments have failed. REMICADE is a biologic therapy that recognizes, attaches to, and blocks the action of a protein in your body called tumor necrosis factor alpha (TNF-alpha). TNF-alpha is made by certain blood cells in your body. It is administered through a series of infusions.

Surgery

Approximately half of patients with fulminant colitis require surgery. Surgery usually entails removing the colon and bowel and creating a "pouch" with portions of the small intestine.
