Tropical sprue occurs chiefly in the Caribbean, southern India, and Southeast Asia. Both natives and visitors (who spend at least 1 month in the area) may develop the disease, but children are rarely affected. This disorder has rarely been reported in the United States. Worldwide, its occurrence has been declining in recent decades. The cause is unknown, but available evidence suggests an infectious cause.

Symptoms of Tropical Sprue

Diagnosis of Tropical Sprue

  • Biopsy

  • Blood tests

A doctor considers the diagnosis of tropical sprue in a person with anemia and symptoms of malabsorption who lives in or has recently visited one of the areas in which the disorder commonly occurs.

A doctor confirms the diagnosis by removing tissue (biopsy) from the small intestine using an endoscope (a flexible viewing tube equipped with a light source and a camera through which a small clipper can be inserted) and examining the tissue under a microscope. The doctor can identify some characteristic changes in the person's small intestine. A stool sample is usually analyzed to exclude parasites or bacteria as a cause.

Blood tests are done to help determine whether people have undernutrition.

Treatment of Tropical Sprue

  • Tetracycline

  • Folate and vitamin B12

Treatment of tropical sprue usually results in a full recovery.

A person suspected of having tropical sprue is treated with the antibiotic tetracycline. This drug is given for up to 6 months.

Nutritional supplements, especially folate and injections of vitamin B12, are given for several weeks. Other nutritional replacements are given as needed.
