Case Report: Whipple’s disease pneumonia caused by inhalation of gas or liquid
Abstract
Tropheryma whipplei (T. whipplei) is a Gram-positive bacterium that causes rare clinical infections, which primarily manifest as gastrointestinal infections and, more rarely, pulmonary diseases. Furthermore, immunosuppression is considered a predominant risk factor for T. whipplei infection. Several studies have indicated an association between T. whipplei infection and immunocompromised conditions; however, a few studies have also revealed that aspiration may be a potential predisposing factor for T. whipplei-related aspiration pneumonia. This case study reports two different cases of aspiration-induced T. whipplei pneumonia, each exhibiting unique clinical manifestations, imaging features, and therapeutic responses. Both patients had a history of aspiration, and their diagnoses were confirmed via mNGS. They were treated with sulfamethoxazole–trimethoprim (SMZ), which effectively alleviated the symptoms of mild T. whipplei pneumonia. However, in one case, the patient suffered from a severe co-infection of T. whipplei and Aspergillus following a drowning incident, which was effectively treated with meropenem and voriconazole co-therapy. This study provides novel data on T. whipplei infection and improves clinical awareness of aspiration-related pneumonia.
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.
