ABSTRACT
Introduction: Since the coronavirus disease 2019 (COVID-19) emerged in Wuhan, neurological complications affecting both the central and peripheral nervous systems have been reported. Multiple etiological mechanisms as immuno-mediation, direct nerve infection, prolonged intensive care units (ICU) hospitalization and prolonged positioning have been proposed as a cause of peripheral lesion. The aim of this study is to report an observational description of peripheral nervous system complications in patients with severe COVID-19. Method(s): We include patients with COVID-19 infections with weakness or sensory deficit, with one or more EMG tests carried out between April 2020 and December 2021. Standard neurophysiological techniques with motor and sensory nerve conductions, F responses and needle EMG exam in representative upper and lower limb muscles were performed. Result(s): A total of 89 patients were included, 66 males (74%) and 23 females (26%), with an average age of 55.7 years old (range from 11 to 90). Most of them (74%) were studied during hospitalization (16 of them during ICU admission). Nearly all patients (90%) had a prolonged ICU hospitalization (between 8 and 120 days). The reason for consultation was diffuse or focal weakness, difficulty in weaning, facial palsy or sensory deficits. The results of EMG tests showed myopathic findings in 61% of patients, focal peripheral nerve lesions in 64%, Guillain-Barre syndrome (GBS) in 5 (6%), and other types of peripheral polyneuropathy in 24%. From peripheral nerve injuries, peroneal neuropathy was the most frequent (58%), brachial plexopathy was found in 26%, median neuropathy in 25%, ulnar in 11%, lateral femoral cutaneous in 9%, axillary and spinal in 5%, radial and hypoglossal in 4% and musculocutaneous in 2%. Tapia's syndrome was diagnosed in two patients. Peripheral nerve injuries correlated with longer admissions in ICU and prone positioning. The follow-up studies showed a good recovery from myopathy but persistent motor sequelae in axonal GBS patients and in most peroneal nerve injuries. Neurophysiological findings are described. Conclusion(s): Peripheral nerve complications are frequent in patients affected by severe COVID-19 and prolonged hospitalization, mainly focal nerve injuries (61%), critical illness myopathy (64%) and peripheral polyneuropathy (30%) including GBS (5 patients). Prone and prolonged positioning in ICU may be associated with peripheral nerve injuries although other mechanisms cannot be excluded. Copyright © 2022
ABSTRACT
INTRODUCTION: The massive vaccination against the SARS-CoV-2 virus has demonstrated to be one of the major measures for the reduction of the morbidity and mortality that this virus causes. However, during the last months the administration of the vaccine has been also associated with some rare, but life-threatening, adverse effects. CASE REPORT: In this article we describe the case of a patient that developed a Guillain-Barre syndrome and an Idiopathic thrombocytopenic purpura nine days after the vaccination with the third dose for the SARS-CoV-2 virus (Moderna). He had received previously two doses of the AstraZeneca vaccine. Moreover, the patient was positive for auto-antibodies anti-SSA/Ro60 and auto-antibodies IgG anti-GM1 and IgG anti-GM3. DISCUSSION: Even though it is not possible to stablish a clear relation of causality between the administration of the vaccine booster for SARS-CoV-2 and the diseases developed by the patient, the association of two concomitant autoimmune processes is remarkable. As well as the positivity for the auto-antibodies anti-SSA/Ro60, which have been described in the bibliography in cases of SARS-CoV-2 infection.
TITLE: Síndrome de Guillain-Barré y trombocitopenia tras la vacunación contra el SARS-CoV-2 con Moderna. Descripción de un caso.Introducción. La vacunación masiva contra el virus SARS-CoV-2 constituye una de las principales estrategias en la reducción de la morbimortalidad que presenta dicho virus. No obstante, a lo largo de los últimos meses, su administración también se ha relacionado con diversos efectos adversos raros, pero potencialmente graves. Caso clínico. En el presente artículo describimos el caso de un paciente que desarrolló un síndrome de Guillain-Barré y una púrpura trombocitopénica idiopática nueve días después de la vacunación con la tercera dosis contra el virus SARS-CoV-2 (Moderna), con dos dosis previas de AstraZeneca. Adicionalmente, destaca la presencia de positividad para autoanticuerpos anti-SSA/Ro60 y para anticuerpos inmunoglobulina G anti-GM1 e inmunoglobulina G anti-GM3. Conclusión. Aunque no es posible establecer una relación de causalidad entre la administración del booster de la vacuna y el desarrollo de la enfermedad, es destacable la asociación de dos procesos autoinmunes concomitantes, junto con la positividad en los autoanticuerpos anti-SSA/Ro60, lo cual se ha descrito en la bibliografía en casos de infección del virus SARS-CoV-2.
