Study Notes
- Tropical sprue affects people in tropical countries between the Tropics of Cancer and Capricorn, and sporadic cases are seen among immigrants and returning tourists from these areas.
- The cause of tropical sprue is unknown, but it is likely caused by an infectious agent or alterations in intestinal bacteria due to environmental factors.
- Symptoms include diarrhea, steatorrhea, weight loss, nausea, anorexia, and anemia.
- Anemia is often megaloblastic and reflects deficiencies in vitamin B12 or folate, or both.
- Diagnosis relies on excluding other diseases with similar symptoms, such as celiac sprue and protozoal infections.
- Treatment includes tetracycline and high-dose folic acid, as well as correcting nutritional deficiencies.
- The optimal duration of treatment is unclear, but 1 month appears to be sufficient for most travelers and expatriates, while 6 months to 1 year is recommended for chronically ill residents in the tropics.
- The response to treatment is usually prompt, and the prognosis with proper treatment is excellent.
- Relapses can occur months to years after treatment.
- Response to treatment may be more predictable among those with tropical sprue acquired in the Caribbean than in Asia, but comparative studies are not available.
