Abstract
Whipple's disease (WD) is a rare disorder caused by the pathogenTropheryma whipplei (T. whipplei). We report a unique presentation of WD in which the patient did not exhibit arthralgia which is characteristic of this disease. A 67-year-old man with a history of chronic hepatitis B infection and human immunodeficiency virus (HIV) infection presented with weight loss, nausea, vomiting, and myalgia.Endoscopy demonstrated erythema in the gastric body, lymphangiectasia of the duodenum, and increased granularity of the terminal ileum. Mucosal biopsies revealed macrophages in the lamina propria with focal histiocytic aggregates throughout the small bowel and cecum, consistent with WD. ConfirmatoryT. whippleipolymerase chain reaction(PCR) testing was positive. WD is a rare diagnosis that must be considered in the differential diagnoses of patients presenting with unexplained nausea, vomiting, diarrhea, and anemia. Furthermore, in patients with HIV, the possibilities would also include opportunistic gastrointestinal pathogens. Classic WD is characterized by diarrhea, weight loss, abdominal pain, and extra-intestinal involvement manifesting as joint pain. We describe a case of WD occurring in a patient with HIV, without the disease's characteristic joint involvement.
