Guillain-Barré Syndrome and Unilateral Optic Neuritis Following Vaccination for COVID-19: A Case Report and Literature Review

Guillain-Barré syndrome after COVID-19 vaccination: A systematic review and analysis of case reports

INTRODUCTION

Cases of Guillain-Barré Syndrome (GBS) have been believed to be associated with the novel COVID-19 infection, and also with the following vaccines developed against the infection. Our work aims to investigate the incidence of GBS after COVID-19 vaccination, and describe its clinical characteristics and potential confounders.

METHODS

An electronic search was conducted through four databases: PubMed, Scopus, medRxiv, and Google Scholar for all case reports and case series describing after COVID-19 vaccine administration. All published articles from inception until November 1st, 2022 were included. Differences between groups were assessed using Pearson chi-square test. Modified Erasmus GBS Outcome Score (mEGOS) for the ability to walk after GBS was calculated for all cases with sufficient clinical data, and Kaplan-Meier survival analysis was performed to study the effect of vaccine type on the relationship between vaccination time and complication of GBS.

RESULTS

About 103 studies describing 175 cases of GBS following COVID-19 vaccination were included. The Acute Inflammatory Demyelinating Polyradiculoneuropathy subtype was the most reported subtype with 74 cases (42.29%). The affected age group averaged around 53.59 ±18.83 years, with AMSAN occurring in a rather older group (63.88 ±20.87 years, p=0.049). The AstraZeneca vaccine was associated with AIDP (n=38, 21.71%) more than other vaccines, p=0.02. The bilateral facial palsy subtype was mostly linked to adenoviral vector vaccinations, accounting for an average of 72% of the total BFP cases. Dysesthesias was the most reported sensory complication (60%, p=0.349). Most GBS patients survived (96%, p=0.036), however, most patients had low mEGOS scores (4 ±3.57, p<0.01). On average, patients developed GBS at 13.43 ±11.45 days from vaccination (p=0.73), and survival analysis for complication of GBS into mechanical ventilation or walking impairment yielded a severely increased probability of complication after 25 days (p<0.01). Intravenous immunoglobulins (p=0.03) along with rehabilitation (p=0.19) were the most commonly used treatment.

CONCLUSION

This work investigates the incidence of Guillain-Barré Syndrome after COVID-19 vaccination. Most cases occurred after receiving the AstraZeneca or Pfizer vaccines, and despite low mortality rates, ambulation was compromised in most patients. A higher risk of GBS complication is associated with an onset later than 12-13 days, particularly with Pfizer, AstraZeneca, and Moderna vaccines. No specific predisposing or prognostic factor was identified, and the relation between the COVID-19 vaccines and GBS remain unclear.

Neuromuscular diseases associated with COVID-19 vaccines: a systematic review and pooled analysis of 258 patients

BACKGROUND

Neuromuscular diseases (NMD) emerged as one of the main side effects of the COVID-19 vaccination. We pooled and summarized the evidence on the clinical features and outcomes of NMD associated with COVID-19 vaccination.

METHODS

We comprehensively searched three databases, Medline, Embase, and Scopus, using the key terms covering "Neuromuscular disease" AND "COVID-19 vaccine", and pooled the individual patient data extracted from the included studies.

RESULTS

A total of 258 NMD cases following COVID-19 have been reported globally, of which 171 cases were Guillain-Barré syndrome (GBS), 40 Parsonage-Turner syndrome (PTS), 22 Myasthenia Gravis (MG), 19 facial nerve palsy (FNP), 5 single fiber neuropathy, and 1 Tolosa-Hunt syndrome. All (100%) SFN patients and 58% of FNP patients were female; in the remaining NMDs, patients were predominantly male, including MG (82%), GBS (63%), and PTS (62.5%). The median time from vaccine to symptom was less than 2 weeks in all groups. Symptoms mainly appeared following the first dose of vector vaccine, but there was no specific pattern for mRNA-based.

CONCLUSION

COVID-19 vaccines might induce some NMDs, mainly in adults. The age distribution and gender characteristics of affected patients may differ based on the NMD type. About two-thirds of the cases probably occur less than 2 weeks after vaccination.

Systematic review exploring the clinical features of optic neuritis after SARS-CoV infection and vaccination

BACKGROUND

This study aims to characterise the symptoms and clinical features of optic neuritis (ON) following SARS-CoV-2 infection and vaccination.

METHOD

A literature search was conducted in four databases (PubMed, Medline, Embase and Google Scholar) to identify relevant case reports and case series. The records were screened and articles adhering to the inclusion criteria were critically appraised.

RESULTS

Sixty-eight studies were found to be eligible for inclusion, including 34 reporting ON following SARS-CoV-2 infection and an equal number reporting cases postvaccination. In total 93 patients and 125 eyes were included. The infection cohort included 42 patients and 56 eyes, 51.2% were female and 33.3% experienced bilateral ON. The mean visual acuity was 1.64 log of minimum angle of resolution (LogMAR), while pain was present in 77.8%. Oligoclonal bands were present in 3 patients, myelin oligodendrocyte glycoprotein (MOG) antibodies in 18 patients and AQP-4 antibodies in 4 patients. The vaccination cohort included 51 patients and 69 eyes. 60.8% were female and 35.3% had a bilateral ON. The mean visual acuity was 0.93 LogMAR. Oligoclonal bands were present in 46.7%, MOG antibodies in nine patients and AQP-4 antibodies in three patients.

CONCLUSION

Patients with ON post-SARS-CoV infection were more likely to experience severe visual impairment than in cases following vaccination. Further research is required to outline the clinical features of ON after COVID-19 infection and vaccination, and establish causality.

[Combination of post-infectious optic neuritis and Guillain-Barré syndrome]

The coexistence of optic neuritis and Guillain-Barré syndrome is a rare combination of neurological diseases. The trigger of an autoimmune inflammatory process is often a respiratory mycoplasma infection. Ignorance of such combination can lead to diagnostic and therapy mistakes. This article describes the case of a rare combination of overlapping optic neuritis and Guillain-Barré syndrome, associated with Mycoplasma pneumoniae and provides the short literature review. Further studies are required to identify common pathogenetic mechanisms of combined inflammatory lesions of the optic nerves and peripheral nervous system.

Bilateral Optic Neuritis and Facial Palsy Following COVID-19 Infection

Cases of optic neuritis have been reported following the novel coronavirus disease 2019 (COVID-19), with most being unilateral and associated with demyelinating illness. We report a case of a 22-year-old woman who presented with sudden onset painless diminution of vision in both eyes six weeks following COVID-19 infection. She also had a history of left lower motor neuron (LMN) facial palsy immediately following COVID-19 disease that recovered fully on steroids. Ocular examination and ancillary and laboratory investigations pointed to bilateral atypical optic neuritis. The patient responded well to the standard optic neuritis treatment protocol. We diagnosed her as a case of left LMN facial palsy and parainfectious bilateral optic neuritis following COVID-19. Parainfectious bilateral optic neuritis and facial nerve palsy associated with COVID-19 can occur following COVID-19 disease. Ours is the first case to report the occurrence of both in a patient.
