Lymphoma combined with Tropheryma whipplei infection: A case report and literature review
Abstract
Rationale: Whipple disease is exceptionally rare in patients with lymphoma in China, particularly when presenting with pulmonary symptoms as the initial manifestation. Respiratory involvement is atypical for Whipple disease and may easily be overlooked, especially in patients receiving targeted drug therapy for lymphoma. In such cases, it can be challenging to distinguish between disease progression, drug-induced pneumonia, and infectious etiologies, as the clinical and radiological findings often overlap.
Patient concerns: A 39-year-old patient with lymphoma and persistent fever did not respond well to the broad-spectrum antibiotics.
Diagnoses: In contrast to traditional pathological examination or tissue periodic acid-Schiff staining, the patient was diagnosed using metagenomic next-generation sequencing of pulmonary alveolar lavage fluid.
Interventions: Symptomatic treatment, including anti-infective agents, cough relief, and expectorants, was administered. Bronchoscopy and lung puncture were performed to determine the cause of the disease.
Outcomes: Following the confirmation of Tropheryma whipplei by metagenomic next-generation sequencing, targeted antimicrobial therapy was likely initiated. The patient's symptoms, including the persistent fever, subsequently resolved, indicating a positive response to the appropriate treatment.
Lessons: Whipple trophic pneumonia is an opportunistic infection with low incidence. It typically presents with atypical clinical signs and…
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
