A 22-year-old man (with no history of underlying disease) was admitted with dry cough and dyspnea that had developed for 5 days before admission. Vital signs were as follows: body temperature = 36.8°C, systolic blood pressure = 70/50 mmHg, heart rate = 120/min, and O2 saturation = 90% without oxygenation. The ECG showed sinus tachycardia. The patient had a positive nasal and oropharyngeal PCR test for COVID-19, and pulmonary edema was observed by CT scan (Figure ). Echocardiography showed LVEF of 30%–35%, left ventricular end-diastolic diameter of 5 cm, moderate RV enlargement and dysfunction, dilated inferior vena cava, and mild left-sided pleural effusion. The patient received broad-spectrum antibiotics (meropenem [500 mg q8 h for 5 days] and doxycycline [200 mg/day]), high-dose corticosteroid (methylprednisolone 1 g/day), and remdesivir for COVID-19. The patient was discharged after 7 days with stable hemodynamics. Follow-up of the patient for 3 months showed an LVEF of 45% and a normal cTnI value.
A 14-year-old girl with a history of glucose-6-phosphate dehydrogenase (G6PD) deficiency was admitted with fever, cough, and dyspnea that had occurred since a week before admission. Moreover, she experienced loss of consciousness that had arisen about an hour before admission. Vital signs were as follows: body temperature = 38.2°C, systolic blood pressure = 60/50 mmHg, heart rate = 145/min, and O2 saturation = 60% without oxygenation. Also, the GCS score was 12. The ECG showed sinus tachycardia and low-voltage limb leads. So, she was intubated immediately, and vasopressors were administered. The chest CT scan showed bilateral diffuse GGO and consolidations (Figure ) as well as she had a positive nasal and oropharyngeal PCR test for COVID-19. Furthermore, the patient was anemic (hemoglobin = 6 g/dl). Echocardiography demonstrated an LVEF of 15%, no pleural effusion, normal inferior vena cava, pulmonary arterial pressure of 30 mmHg, and normal LV and RV size. The patient received broad-spectrum antibiotics (meropenem [500 mg] and doxycycline [200 mg/day]), high-dose corticosteroid (methylprednisolone 1 g/day), and remdesivir for COVID-19. However, the patient died in virtue of acute respiratory distress syndrome (ARDS).
