An 18-year-old woman (with no underlying disease) was admitted with a sudden loss of consciousness, fever, and headache that had occurred for 2 days before admission. At the time of admission, vital signs were as follows: body temperature = 36.8°C, systolic blood pressure = 80/60 mmHg, heart rate = 110/min, and O2 saturation = 80% without oxygenation. Glasgow Coma Scale (GCS) score was 11. She was intubated and treated with vasopressors. Also, rales were heard on pulmonary auscultation. Initial electrocardiogram (ECG) demonstrated sinus tachycardia (110/min) and low voltage QRS. Transthoracic echocardiography (TTE) indicated a small left ventricle (LV) with an end-diastolic dimension of 42 mm, a left ventricular ejection fraction (LVEF) of 10% with global hypokinesis, a normal right ventricle (RV), and pulmonary arterial pressure (PAP), no pericardial effusion (PE) or thrombosis, and no significant valve lesions or dysfunction. Chest computed tomography (CT) scan revealed diffuse bilateral ground-glass opacities (GGO) and basal consolidations (Figure ). Moreover, the patient had a positive nasal and oropharyngeal polymerase chain reaction (PCR) test for COVID-19. Laboratory findings are summarized in Table . The patient received intravenous immunoglobulin (IVIG; 1 g/kg), broad-spectrum antibiotics (meropenem [500 mg] and doxycycline [200 mg/day]), high-dose corticosteroid (methylprednisolone 1 g/day), and remdesivir for COVID-19. However, she died due to cardiac arrest (less than 24 h after admission).
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).
