section of this report.
Malabsorption, multiple nutritional deficiencies, and abnormalities in
the small bowel mucosa are the chief characteristics in Tropical Sprue, a
disorder of unknown cause. The disease is acquired and appears to be related
to environmental and nutritional conditions. It is most prevalent in the
Caribbean, south India, and southeast Asia.
Symptoms
Symptoms of Tropical Sprue may include fatigue, diarrhea with stools that are
copious, pale and malodorous, anorexia, loss of weight, asthenia (loss of
strength and energy) and general weakness.
The onset of the disorder may be acute. There may be fever and an
inflammation of the mouth and tongue. The skin may be dry and there may be
scaling apparent on the lips and at the angles of the mouth. Some patients
may experience mental depression.
Some patients experience spontaneous remission. Treatment of the
disorder in its early stages may result in rapid and complete recovery. The
restoration of normal intestinal structure and function may be slower if
treatment is begun later in the course of the disease. Tropical Sprue may
become chronic with frequent relapses.
Malabsorption of fats and xylose, reduction in the absorption of iron,
vitamin B12, and folate, and megaloblastic anemia are common findings.
Causes
Tropical Sprue is a disease of unknown cause. It is an acquired disorder
which appears to be related to environmental and nutritional conditions. The
disease may be related to an infectious organism (either viral or bacterial),
dietary toxin, parasitic infestation, or a nutritional deficiency such as
folic acid. Damage to intestinal mucosa which results in an impairment of
the absorption of foods, minerals, and water may be produced by these agents.
Affected Population
Tropical Sprue occurs chiefly in the Caribbean area, south India, and
southeast Asia. Both residents of the area and visitors can be affected.
Therapies: Standard
Treatment for Tropical Sprue includes the use of folic acid and tetracycline
or oxytetracycline or ampicillin. The dosage depends on the severity of the
disorder as well as how the patient responds to the therapy. Other
replacement therapy is given as needed (e.g., iron, vitamin B12). Diarrhea
may be controlled with Lomotil or Imodium.
Therapies: Investigational
