Tropical malabsorption

Abstract

Tropical malabsorption remains an important clinical problem for both the indigenous population of tropical countries and for short-term visitors and longer-term residents from the industrialized world. In young children, persistent diarrhea and malabsorption can result in severe retardation of growth and development. The most common cause is an intestinal infection notably the small intestinal protozoa including Giardia intestinalis, Cryptosporidium parvum, Isospora belli, Cyclospora cayetanensis, and the microsporidia. Tropical sprue still remains an important diagnostic option but is less common than it was 20 to 30 years ago. It is important to attempt to make a specific microbiological diagnosis as this will influence the choice of antibiotic. However, if laboratory facilities are not available, it is possible to offer empirical therapy although this may involve a trial of more than one antibiotic.
