The first patient was a 12-year-old hispanic male with obesity and mild asthma. He presented with 1 day of fever, odynophagia, cough, dyspnoea, and headache. Physical examination revealed a patient that appeared mildly ill but was non-toxic, smiling and talkative, febrile to 39·5°C, tachypnoeic with a respiratory rate of 34, tachycardic to 150 beats per minutes (bpm), with a normotensive blood pressure of 109/52, and an oxygen saturation of 97% on room air. Lung examination revealed mild bibasilar hypoventilation without wheezing, a slightly increased inspiration to expiration ratio without retractions, and no response to a trial of salbutamol. The remainder of the examination returned normal results. During the patient's time in the emergency department, his tachycardia worsened to 170 bpm and the patient presented signs of compensated shock with cold peripheries, a prolonged capillary refill time of 6 s, and an elevated lactate concentration (4·1 mmol/L). He was managed with crystalloid boluses (a total of 60 mL/kg) with an adequate response. Laboratory tests showed no elevation in inflammatory markers but did show lymphocytopenia. The chest X-ray was unremarkable. The SARS-CoV-2 nasopharyngeal swab PCR was positive. Over the following 8 h, his vital signs and perfusion normalised and his condition improved. Blood cultures were sterile. The final diagnosis was COVID-19-compensated septic shock. The patient returned home, but presented again to the emergency department on day 3 with a non-specific non-petechial pruritic maculopapular rash on the trunk and arms, without systemic symptoms, thought to be of viral aetiology, probably related to COVID-19. The patient returned home; a phone call to the family revealed no further complications and the patient had not required any further medical care.

The second patient was a previously healthy 10-year-old mixed-race (Asian and white) male with obesity. He presented with 5 days of fever to 40°C, cough, odynophagia, vomiting, and abdominal pain. Physical examination showed a patient that was ill but did not appear toxic, conversant but mildly anxious, well hydrated, tachycardic to 120 bpm, hypotensive to 85/50 mmHg, tachypnoeic with an respiratory rate of 36, and with oxygen saturation of 89–95% on room air. He had basilar hypoventilation and otherwise normal breath sounds without retractions. His abdomen was diffusely tender, with guarding and rebound tenderness. Hypotensive shock was managed with serial boluses of crystalloids (total of 60 mL/kg), broad-spectrum antibiotics, and inotropic support with adequate response. Lactate concentration (4·0 mmol/L) and inflammatory markers were elevated with lymphocytopenia, and liver function testing showed mild elevated transaminases with a markedly increased conjugated bilirubin. Renal function revealed prerenal acute renal failure. CT imaging revealed a right upper lobe consolidation with bilateral pleural effusions and ileocolitis with signs of terminal ileitis and reactive appendicitis. He was started on hydroxychloroquine and azithromycin and required non-invasive mechanical ventilation for 5 days. No operative intervention was required. Blood and urine cultures were sterile. Nasopharyngeal PCRs for SARS-CoV-2, mycoplasma, and chlamydia returned negative. Other viral testing including hepatitis A, hepatitis B, and hepatitis E, cytomegalovirus, Epstein-Barr virus, HIV, and adenovirus revealed no signs of acute infection. SARS-CoV-2 infection was confirmed serologically. The final diagnosis was COVID-19 hypotensive septic shock associated with MODS. The patient has been discharged from hospital.

The third patient is a previously healthy 10-year-old black male with obesity who presented in hypotensive shock after 7 days of fever, vomiting, and severe abdominal pain. Examination revealed a patient that appeared toxic, conscious and orientated, tachypnoeic with a respiratory rate of 39, tachycardic to 117 bpm, with systolic hypotension to 85 mmHg despite a crystalloid volume bolus (20 mL/kg) administered during pre-hospital care, and with a saturation of 98% on room air. The lung examination was otherwise healthy and the abdomen was tender, with generalised guarding. His lactate concentration was mildly elevated (2·8 mmol/L). Volume resuscitation (a total of 50 mL/kg of crystalloids), septic work-up, broad-spectrum antibiotic therapy, and vasopressor support were initiated. The initial chest radiograph was unremarkable. Laboratory results revealed marked inflammatory marker elevation with lymphopenia and evidence of MODS, with acute renal failure and cholestasis. A CT scan showed diffuse bilateral consolidations, predominantly in the posterior aspects of the upper and inferior lobes (figure) and mesenteric lymphadenitis without evidence for surgical pathology. Other viral testing including hepatitis A, hepatitis B, and hepatitis E, cytomegalovirus, Epstein-Barr virus, HIV, adenovirus, rotavirus, and a comprehensive respiratory viral panel by PCR revealed no signs of acute infection. A SARS-CoV-2 infection was confirmed serologically. The patient's respiratory status further deteriorated despite non-invasive mechanical ventilation and required intubation. The patient was started on hydroxychloroquine and azithromycin and, for suspicion of a cytokine storm, started on anakinra. Renal function deteriorated, attributed to prerenal and renal injury, and the patient required haemodialysis. Echocardiography on hospital day 8 showed left anterior descending artery and right coronary aneurysms, with Z-scores of 4·53 and 3·30, respectively. The patient has since been transferred out of the intensive care unit, but remains in hospital.
