Immunodeficient patients are less prone to develop serious complications of COVID-19 and cytokine storm. However, they are more likely to develop opportunistic infections that can mimic the symptoms of the SARS-CoV-2. we presented a 27-year-old male case of SARS-CoV-2, who was complicated with Pneumocystis jirovecii pneumonia, following treatment with rituximab.

Over the course of the Coronavirus disease 2019 (COVID-19) pandemic, numerous complications have been documented. In this report, we have detailed an unexpected complication of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection that occurred in a 73-year-old female patient who was simultaneously afflicted with mucormycosis and another unanticipated problem. Due to the lack of recovery of the patient after receiving mucormycosis treatment and continued fever, cough and hemoptysis, bronchoscopy was performed for her. During bronchoscopy, we encountered a foreign body that was the cause of the patient's fever, cough, and hemoptysis. Rigid bronchoscopy was performed and a foreign body (2.7 x 1.2 cm) was removed from the left main bronchus. Although research has showed fewer cases of pediatric Foreign Body Aspiration (FBA) during lockdown periods, there is not enough evidence about FBA risk in elderly patients with comorbidities. Finally, in the treatment of cases of COVID-19 infections co-infected with opportunistic fungal and maybe even bacterial infections, we should not look at the patient through a tunnel vision and consider all possible scenarios for the patient.

Although immunodeficient patients are less prone to develop Coronavirus disease 2019 (COVID-19)-mediated cytokine storm, secondary infections can cause serious complications in this vulnerable population. They are more likely to develop opportunistic infections that can mimic the symptoms of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Herein, we presented a 27-year-old male patient of SARS-CoV-2 infection, who was complicated with Pneumocystis jirovecii pneumonia (PJP), following treatment with rituximab. First, he was hospitalized for 5 days with fever, cough, and dyspnea due to COVID-19 infection, and treated with remdesivir and glucocorticoid. Then, he has been referred to our center with cough, dyspnea, body pain, and fever. Due to persistent fever, the progression of pulmonary lesions, and reduced oxygen saturation, we began treatment with piperacillin + tazobactam, vancomycin, and levofloxacin. Nevertheless, the patient's fever did not stop after the aforementioned empiric treatment and his condition got worse and he was admitted to the intensive care unit. The result of BAL fluid, tested for P. jirovecii by RT-PCR, turned out to be positive. Therefore, we started trimethoprim-sulfamethoxazole and dexamethasone, which improved his condition. We hope this article helps clinicians consider causes other than COVID-19, especially opportunistic infections such as PJP, in patients with respiratory symptoms and fever.
