ResumoA 9-year-old girl was admitted to the paediatric intensive care unit (PICU) with a history of high-grade fever for 14 days, throbbing frontal headache, vomiting, and progressive weakness on the right side of her body for 5 days. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RNA was detected on nasopharyngeal swab by RT-PCR on presentation. On admission to the PICU (day 1), she had bilateral non-purulent conjunctivitis, high-grade fever (axillary temperature using digital thermometer of 39·4°C), blood oxygen saturation of 98%, a heart rate of 64 bpm, tachypnoea, and hypertension (132/102 mm Hg). The patient had a Glasgow Coma Score (GCS) of 11 (E3, V2, M6), upper motor neuron type right-sided seventh cranial-nerve palsy, complete hemiplegia, brisk deep tendon reflexes, and extensor plantar response on the right. Her pupils were normal and she had no signs of meningeal irritation. Her paediatric quick sequential organ function assessment (qSOFA) score was 2 (of 3) on admission.1Tiwari L Anand C Kumar G Chaturvedi J Mishra NR Abstract PCCLB-42: new predictive score for PICU: pediatric quick SOFA score—AIIMS Patna model.Pediatr Crit Care Med. 2018; 19: 256Crossref Google Scholar The suspected causes for her neurological signs included COVID-19 associated encephalitis or stroke. She received tier 1 and tier 2 management for raised intracranial pressure—ie, mechanical ventilation, thermoregulation, sedation, and head-elevation to 30° (tier 1) and osmotherapy (glycerol, 3% hypertonic saline, and intermittent mannitol) and intermittent hyperventilation (tier 2), and other supportive care (eg, optimisation of intravascular volume, maintenance of normoxemia, and prevention and treatment of fever and seizures).2Singhi SC Tiwari L Management of intracranial hypertension.Indian J Pediatr. 2009; 76: 519-529Crossref PubMed Scopus (30) Google Scholar Empirical antibiotics included ceftriaxone, vancomycin, and azithromycin. She had normal blood counts and renal function, mild transaminitis, high CRP, high ESR, high D-dimer, and increased triglyceride and ferritin concentrations, suggestive of a hyperinflammatory response (table). Chest x-ray showed bilateral ground-glass opacification and reticulonodular opacity.TableLaboratory results on admissionResultNormal valueHaemoglobin, g/dL11·312–15Platelets, ×103 cells per mm32·51·5–4·5Leucocyte count, cells per mm369804000–11 000Serum bilirubin (total), mg/dL0·520·3–1·2Serum bilirubin (direct), mg/dL0·17<0·3Aspartate aminotransferase, IU/L53·4<31Alanine aminotransferase, IU/L126·110–28Alkaline phosphatase, IU/L208·9100–290Triglycerides, mg/dL416·6<150Prothrombin time, s14·2<14Urea, mg/dL31·813–43Creatinine, mg/dL0·350·7–1·3Uric acid, mg/dL3·173·5–7·2Serum sodium, meq/L132·8135–145Serum potassium, meq/L3·683·5–5LDH, U/L1000·8230–460CBNAAT for Mycobacterium tuberculosisAcid fast bacilli not shown..CRP, mg/L64·90–5ESR, mm/h500–15D-dimer, μg/mL3·57<0·2Ammonia, μmol/L76·210–47Ferritin, ng/L614·610–291CPK-MB, U/L20·15–25Troponin-I, ng/mL0·0060·02–0·06CSF cells, cells per mm350 (lymphocytes 80%, polymorphs 20%)0–5CSF glucose, mg/dL4540–70CSF protein, mg/dL60·115–40CSF ADA, U/L2·70–5CSF LDH, U/L102·6230–460CSF CBNAAT for Mycobacterium tuberculosisNegativeNegativeCSF acid fast bacilliAbsentAbsentCSF IgM for Japanese encephalitis and herpes simplex virusNegativeNegativeCSF cultureSterileSterileGastric aspirate for acid fast bacilliNegativeNegativeMalarial parasite blood smearNegativeNegativeANA serologyNegativeNegativeVasculitis profileNegativeNegativeSickling testNegativeNegativeCOVID-19 antibody testPositive (week 4 of admission)NegativeWidal test for salmonella typhi, dengue-NS1 antigen, dengue IgM and IgG antibody, rapid test for scrub typhus, leptospira IgM, HBsAg, hepatitis C antibody testNegativeNegativeADA=adenosine deaminase.

She deteriorated with worsening GCS, bradycardia, and cardiac arrest on day 3 of PICU admission. Return of spontaneous circulation was achieved after 2 mins of chest compression and ventilation. Her SOFA score worsened from 2 to 12, therefore requiring higher ventilatory, vasoactive, and inotropic support for respiratory failure, shock, and autonomic instability (appendix). Echocardiography did not show valvular defect or coronary artery dilatation. Her ECG, serum sample of myocardial creatine phosphokinase (CPK-MB), and troponin I measurements were normal. An unenhanced CT scan showed multifocal discrete and confluent hypodensities, suggestive of infarcts, in the genu and adjacent body of corpus callosum, left basal ganglia, and bilateral thalami, with mild oedema and mild mass effect over the lateral ventricle. Subsequently, a CT angiography showed multifocal smooth stenosis of both intracranial internal carotid arteries, right middle cerebral artery, and both A2 segments of the anterior cerebral arteries. Diffuse narrowing of the M2 and M3 segment branches of both middle cerebral arteries was also seen (figure). To further investigate rarer causes of childhood stroke the following tests were done, all were negative: anti-nuclear antibody, vasculitis profile, and sickle cell screen (table). There was no history of neck trauma that suggested arterial dissection. She had no history of skin lesions that were suggestive of varicella (chickenpox) in the past or during current illness. Cerebrospinal fluid examination showed pleocytosis with slightly increased protein (table) but tested negative for SARS-CoV-2 using RT-PCR. No organism was detected in cerebrospinal fluid or blood despite extensive tests for possible organisms (table). Test for IgM and IgG antibody for varicella zoster virus could not be reported because the test kit was not available. Additional treatment included intravenous immunoglobin (2 g/kg over 2 days), methylprednisolone (30 mg/kg per day intravenously for 5 days) followed by dexamethasone (0·15 mg/kg per day for 2 weeks), remdesivir (5·0 mg/kg by intravenous infusion over 1 h, followed by 2·5 mg/kg per day by intravenous infusion for 5 days), and low-molecular-weight heparin (1 mg/kg subcutaneously twice daily for 2 weeks followed by once daily for 1 week). Her clinical status improved progressively (appendix), and she was weaned off mechanical ventilation on day 12. Her serum CRP, ferritin, and lactate dehydrogenase values returned to normal. COVID-19 RT-PCR on nasopharyngeal swab and bronchoalveolar lavage was negative on day 12 of stay in the PICU. A serum COVID-19 antibody test (done after 4 weeks of admission) was positive. She showed slow but consistent improvement over the next 3 weeks, reaching a GCS of 13 (E4, V3, M6) and power of 2–3 of 5 on the affected side. She transferred from PICU to a paediatric ward where she continues to receive psychomotor rehabilitation for her residual illness.

In one of the first reports of PIMS-TS, the patient who died despite extensive organ support (mechanical ventilation, renal replacement therapy, and extracorporeal membrane oxygenation) had developed right middle cerebral artery and ACA ischaemic infarcts. That patient was confirmed as SARS-CoV-2 positive at post-mortem analysis.11Riphagen S Gomez X Gonzalez-Martinez C Wilkinson N Theocharis P Hyperinflammatory shock in children during COVID-19 pandemic.Lancet. 2020; 395: 1607-1608Summary Full Text Full Text PDF PubMed Scopus (1738) Google Scholar In our case, early manifestation of stroke and aggressive therapy to halt the cytokine storm seems to be crucial for reaching a positive outcome. The differential diagnosis of stroke in children is broad. Common causes—such as intracranial bleed, prevalent viral encephalitis, bacterial meningoencephalitis, brain abscess, tubercular meningitis, and cardiac thromboembolism—were ruled out. There was no history to suggest varicella encephalitis, although antibodies for varicella zoster virus could not be tested. We also ruled out other rare causes of acute ischaemic stroke (table). Neurological presentations associated with COVID-19 and similar strains in adults include altered consciousness, headache, dizziness, anosmia, dysgeusia, seizures, stroke, Guillain-Barré syndrome, and neuropsychiatric symptoms.7Garg RK Paliwal VK Gupta A Encephalopathy in patients with COVID-19: a review.J Med Virol. 2020; (published online June 19.)https://doi.org/10.1002/jmv.26207Crossref Scopus (134) Google Scholar, 8Abdel-Mannan O Eyre M Löbel U et al.Neurologic and radiographic findings associated with covid-19 infection in children.JAMA Neurol. 2020; (published online July 1.)https://doi.org/10.1001/jamaneurol.2020.2687Crossref PubMed Scopus (287) Google Scholar SARS-CoV-2 is reported to have a 7·6 times increase (95% CI 2·3–25·2) in the risk of resulting in a stroke in comparison with other coronavirus and seasonal infections in adults.12Merkler AE Parikh NS Mir S et al.Risk of ischemic stroke in patients with COVID-19 versus patients with influenza.JAMA Neurol. 2020; (published July 2.)https://doi.org/10.1101/2020.05.18.20105494PubMed Google Scholar Pathophysiology of acute ischemic stroke in COVID-19 is not fully elucidated yet, although possible mechanisms could be immune mediated or para-infectious events, a hypercoagulable state from systemic inflammation and cytokine storm, viral mimicry of the host resulting in autoantibodies, viral super antigen sequences, antibody or T-cell recognition of viral antigens, or formation of immune complexes.6Jiang L Tang K Levin M et al.COVID-19 and multisystem inflammatory syndrome in children and adolescents.Lancet Infect Dis. 2020; (published online Aug 17.)https://doi.org/10.1016/S1473-3099(20)30651-4Summary Full Text Full Text PDF Scopus (554) Google Scholar, 8Abdel-Mannan O Eyre M Löbel U et al.Neurologic and radiographic findings associated with covid-19 infection in children.JAMA Neurol. 2020; (published online July 1.)https://doi.org/10.1001/jamaneurol.2020.2687Crossref PubMed Scopus (287) Google Scholar, 13Ellul MA Benjamin L Singh B et al.Neurological associations of COVID-19.Lancet Neurol. 2020; 19: 767-783Summary Full Text Full Text PDF PubMed Scopus (1412) Google Scholar, 14Paniz-Mondolfi A Bryce C Grimes Z et al.Central nervous system involvement by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2).J Med Virol. 2020; 92: 699-702Crossref PubMed Scopus (695) Google Scholar Direct viral-induced endothelitis or endotheliopathy, leading to angiopathic thrombosis is also seen in some neurotropic viruses such as Varicella zoster.15Gilden D Cohrs RJ Mahalingam R Nagel MA Varicella zoster virus vasculopathies: diverse clinical manifestations, laboratory features, pathogenesis, and treatment.Lancet Neurol. 2009; 8: 731-740Summary Full Text Full Text PDF PubMed Scopus (424) Google Scholar Endothelial infection by SARS-CoV-2 in the kidney, heart, bowel, and lung at autopsy is reported but cerebral vessels have not yet been investigated.16Varga Z Flammer AJ Steiger P et al.Endothelial cell infection and endotheliitis in COVID-19.Lancet. 2020; 395: 1417-1418Summary Full Text Full Text PDF PubMed Scopus (4567) Google Scholar Initial neuroimaging findings, similar to our described case, are reported in a few adult cases of COVID-19 infection.7Garg RK Paliwal VK Gupta A Encephalopathy in patients with COVID-19: a review.J Med Virol. 2020; (published online June 19.)https://doi.org/10.1002/jmv.26207Crossref Scopus (134) Google Scholar In our case, RT-PCR for COVID-19 was positive on nasopharyngeal swab but negative in cerebrospinal fluid.
