title: [Tropical sprue as the cause of chronic diarrhea after travel to Southeast Asia].
abstract: A 43-year-old woman developed abdominal pain and diarrhea following a travel to Malaysia. Examinations in another hospital proved no evidence of infection, an empirical antibiotic therapy with ciprofloxacin yielded no benefit. One and a half year later, the patient was admitted to our department because of persistent diarrhea and wasting. Laboratory tests showed megaloblastic anemia, folate deficiency and steatorrhea. Stool specimens for bacterial pathogens and parasites were negative. Endoscopy and biopsy from the distal portion of the duodenum revealed broadening and shortening of the villi and an increased infiltration of the lamina propria by chronic inflammatory cells (plasma cells and lymphocytes). In conclusion, diagnosis of tropical sprue was established. The therapy comprised of tetracycline for six weeks and folic acid for six months. Subsequently, the diarrhea disappeared, the patient continuously gained weight and was free of any complaints. The complete remission following this regimen proved the suspected diagnosis. Differential diagnosis in any patient who recently returned from the tropics may be a challenge. Tropical sprue predominantly occurs during or after a longer stay in endemic areas. However, if chronic diarrhea and signs of malabsorption develop after a short journey to India, South-East Asia and parts of the Caribbean, tropical sprue has to be considered, too.
