Melioidosis: Can Tropical Infections Present in Nonendemic Areas? A Case Report and Review of the Literature.

Melioidosis, an infectious disease caused by Burkholderia pseudomallei, is an important cause of sepsis in tropical areas of Eastern Asia, mainly affecting immunocompromised adults. Diabetes mellitus is the most important host risk factor. Here, the authors report a case of a 54-year-old Saudi male with uncontrolled diabetes mellitus for 10 years who presented to our hospital with a 6-week history of fever, cough, night sweats and weight loss. The patient was a frequent traveler to the Philippines, with his last visit being during the rainy season 2 weeks before the onset of symptoms. Definite diagnosis of melioidosis was not made because of insufficient facility to culture the organism in our laboratory; nevertheless, a diagnosis of melioidosis was made based on the cumulative clinical scenario. The patient was discharged on trimethoprim-sulfamethoxazole and doxycycline for 3 months and showed significant improvement at follow-up. For prompt diagnosis and treatment, clinicians must maintain a high index of suspicion for melioidosis in febrile patients with a history of traveling to endemic areas, especially diabetic patients.
