Whipple's Disease Presenting With a Chief Complaint of Dyspnea and Cough From Pulmonary Invasion Without Evidence of Gastrointestinal Involvement.

Abstract

A patient with immune thrombocytopenia, systemic lupus erythematosus on chronic corticosteroids, and interstitial lung disease was referred to the pulmonology clinic due to progressively worsening dyspnea. A bronchoscopy was done and a thorough workup was negative for any infectious pathology or malignancy. A lung biopsy with MicroGenDX test (MicroGen Diagnostics, Lubbock, TX) revealed Tropheryma whipplei, consistent with a Whipple disease diagnosis.Histopathology of biopsy specimens from an esophagogastroduodenoscopy showed moderate chronic active Helicobacter gastritis and unremarkable duodenal specimens without evidence of Tropheryma whipplei. For Helicobacter pylori gastritis, she was prescribed quadruple therapy with omeprazole, bismuth, metronidazole, and tetracycline. For pulmonary Whipple's disease, shecompleted two weeks of IV ceftriaxone, which led to improvement in dyspnea, and then was transitioned to 12 months of oral sulfamethoxazole-trimethoprim. In rare cases, Whipple's disease can present as isolated pulmonary disease without gastrointestinal involvement, especially in immunosuppressed patients with compromised lungs.
