** REMINDER **
The information contained in the Rare Disease Database is provided for

of this report.
Collagenous Colitis is a chronic digestive disease characterized by
changes in the lining of the large intestine (colon). The colon is inflamed
and contains a thickened layer of the protein collagen in its walls.
Chronic diarrhea and weight loss also occur.
Symptoms
Collagenous Colitis is characterized by watery diarrhea that may be recurrent
or chronic. The large intestine is usually inflamed. Mild weight loss and
abdominal pain also occur. In some cases, Collagenous Colitis may
spontaneously go into remission whereas in other cases it may be chronic.
Excessive amounts of a protein (collagen) thickens the wall of the colon
causing symptoms of the disease.
Causes
The exact cause of Collagenous Colitis is not known. The disorder may be
caused by injury to the colon wall or by an inflammation that triggers excess
collagen to accumulate, or by a toxic substance.
Affected Population
Collagenous Colitis affects women in greater numbers than men. Patients are
usually middle-aged when symptoms begin.
Related Disorders
Symptoms of the following disorder can be similar to those of Collagenous
Colitis. Comparisons may be useful for a differential diagnosis:
Ulcerative Colitis (Idiopathic Proctocolitis) is an acute non-specific
inflammatory bowel disorder, characterized by multiple, irregular,
superficial ulcerations. Thickening of the wall of the colon with scar
tissue and polyp-like structures occurs, resulting from prolonged
inflammation. This disorder may involve only the left side of the colon or
may eventually extend to involve the entire bowel simultaneously. Ulcerative
Colitis is usually chronic, with repeated periods of exacerbation and
remission. The chief symptom is bloody diarrhea. (For more information,
choose "Colitis, Ulcerative Colitis" as your search terms in the Rare Disease
Database.)
Therapies: Standard
Treatment for Collagenous Colitis with the antibacterial sulfonamide drug
sulfasalazine may be helpful for reducing inflammation.
Therapies: Investigational
The FDA has approved the following drug for treating as a treatment or
Collagenous Colitis:
The orphan drug Altracin (bacitracin) is being tested for the treatment
of antibiotic-associated pseudomembranous enterocolitis caused by toxins A
and B elaborated by clostridium difficile.
