Clinical characteristics of Guillain-Barre syndrome in COVID-19: a systematic review and meta-analysis of observational studies.

ABSTRACT

Background: Guillain-Barre syndrome (GBS) is a complication that occurs in patients with Coronavirus Disease (COVID-19) infection. The spectrum of symptoms varies from mild to severe symptoms, even death. The study aimed to compare the clinical manifestations in GBS patients with and without COVID-19 comorbidity. Results: A systematic review and meta-analysis of cohort and cross-sectional studies was conducted comparing the characteristics and course of GBS disease in the COVID-19 positive and COVID-19 negative groups. Four articles were selected with a total sample of 61 COVID-19 positive and 110 COVID-19 negative GBS patients. Based on clinical manifestations, COVID-19 infection increased the likelihood of tetraparesis (OR 2.54; 95% CI 1.12-5.74; p = 0.03) and the presence of facial nerve involvement (OR 2.34; 95% CI 1.00-5.47; p = 0.05). Demyelinating type GBS or AIDP was more common in the COVID-19 positive group (OR 2.32; 95% CI 1.16-4.61; p = 0.02). COVID-19 in GBS significantly increased the need for intensive care (OR 3.32; 95% CI 1.48-7.46; p = 0.004) and the use of mechanical ventilation (OR 2.42; 95% CI 1.00-5.86; p = 0.05). Conclusions: GBS following COVID-19 infection showed more severe variations in clinical characteristics compared to the group of GBS patients without COVID-19. Early detection of GBS, especially the typical manifestations post COVID-19 infection, is very important to carry out intensive monitoring and early management before the patient's condition worsens.
