ABSTRACT
Neurological manifestations of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection have been reported in adults and in children, varying from mild to more debilitant symptoms, including fatigue, headache and dizziness. A series of studies have revealed a possible association between Guillain-Barré syndrome (GBS), the most common cause of acute flaccid paralysis at all ages, and SARS-CoV-2 infection. Case reports of novel coronavirus disease 2019 (COVID-19)-associated GBS mainly include adult patients, while only a few pediatric cases have been reported. The present study describes a case of GBS in an Italian 9-year-old girl with previous SARS-CoV-2 infection as a possible trigger, and also conducts a literature review on pediatric COVID-19-associated GBS cases.
ABSTRACT
We describe a rare case of post-infective Acute Motor Axonal Neuropathy (AMAN) variant of Guillain-Barrè Syndrome (GBS) associated with myelitis and anti-GD1b positivity after SARS-CoV-2 infection. The patient referred to the hospital reporting a history of ten days lasting moderate fever, myalgia and anosmia, with the onset of progressive quadriparesis and ascending paraesthesias in the four limbs since five days from defervescence. A chest computed tomography demonstrated interstitial pneumonia with "ground glass opacities", suggesting Coronavirus disease (COVID-19). The patient exhibited three negative reverse-transcription polymerase chain reaction (RT-PCR) nasopharyngeal swabs, while SARS-CoV-2 IgG was found in plasma. The electrophysiological examination demonstrated an AMAN and the spinal cord Magnetic Resonance Imaging (MRI) showed a T2-weighted hyperintense lesion in the posterior part of the spinal cord at the C7-D1 levels. Furthermore, anti-GD1b IgM was detected. GBS and myelitis could exceptionally develop simultaneously. Our findings reasonably support a causality link between COVID-19 and the neurological symptoms, suggesting a post-infective autoimmune reaction.
