Post-COVID-19 severe Pneumocystis jirovecii pneumonia in a non-HIV and immunocompetent patient: A case report and literature review
Abstract
Pneumocystis jirovecii is a ubiquitous opportunistic fungus that can cause life-threatening pneumonia. The clinical manifestations of pneumonia caused by severe acute respiratory syndrome coronavirus 2 and P. jirovecii are similar, posing a significant challenge in the diagnosis of P. jirovecii pneumonia or coronavirus disease 2019. Herein, we report a case of P. jirovecii pneumonia diagnosed through bronchoalveolar lavage and sputum smear analyses. The patient recovered successfully and was discharged following combination therapy with trimethoprim/sulfamethoxazole and corticosteroids. Early diagnosis and prompt treatment are of vital importance in managing P. jirovecii pneumonia, particularly in individuals with related risk factors for P. jirovecii pneumonia development.
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.
