Tropical sprue

Summary

  • This diagnosis should be considered in any patient with diarrhoea and signs and/or symptoms of malabsorption who has spent more than 2 weeks in a tropical region where the disease is endemic.
  • Improvement after folate replacement is prompt and dramatic. Failure to do so should elicit doubt about the diagnosis.
  • No causative microbe has been found, but the condition is likely to result from bacterial infection.
  • In addition to folic acid supplementation, long-term treatment with antibiotics is currently recommended.
  • Deficiencies of folic acid and vitamin B12 and resultant megaloblastic anaemia are the defining characteristics of the disease.
