abstractsWe reported a case of a 65-year-old male who had been treated with obinutuzumab and chemotherapy for follicular lymphoma. He was infected with SARS-CoV-2 after the second course of therapy. He developed fever, cough and bilateral pulmonary infiltrates. His nasopharyngeal swab became negative only temporarily after repeated courses of antiviral therapy, and the symptoms and pulmonary infiltrates waxed and waned. He presented to our hospital with exertional dyspnea and hypoxemia after his nasopharyngeal swab was positive for SARS-CoV-2 for the fourth time. He had an elevated serum lactate dehydrogenase and a positive 1, 3-β-D-glucan test. The PCR test for Pneumocystis jirovecii in the sputum was positive. The patient was diagnosed with persistent COVID-19 and Pneumocystis jirovecii pneumonia. He responded well to the combination treatment of antiviral medication, convalescent plasma, trimethoprim-sulfamethoxazole and corticosteroids.
