Abstract
INTRODUCTION
To describe clinical characteristics and electrophysiological variants of GBS cases during the pandemic, we carried out a comparative analysis between SARS-CoV2 related GBS and non-SARS-CoV2 patients and then compared to the 2019 cases.
PATIENTS AND METHODS
We carried out a cross-sectional study of GBS patients diagnosed according to Asbury and Cornblath criteria. We collected information on clinical and paraclinical variables. We defined a SARS-CoV-2 related GBS case according to the description of Ellul et al. We used Hadden criteria to classify the electrophysiological variants. We performed a comparative analysis between groups.
RESULTS
Fourty-two patients were diagnosed with GBS in 2020, men 64.2%, age 46 ± 17.4 years, patients with obesity/overweight 42.8%, previous diarrhea 31%, history of respiratory tract infection 14.2%. Guillain Barre Disability Scale = 3 points 71.4% and, cranial nerve involvement 69%. The most frequent electrophysiological variant was acute inflammatory demyelinating polyradiculoneuropathy (AIDP) 53.5%. Seven (16.6%) cases were SARS-CoV2 related, four men, age 43.4 ± 13.4 years. When comparing patients with GBS in 2020 vs patients in 2019, we observed a decrease in the previous infection history during 2020 (45.2% vs 73.3%, p-value = 0.005) and a decrease in previous respiratory infection (14.2% vs 33.3%, p = 0.045), as well as a higher frequency of cranial nerve involvement, and albuminocytologic dissociation.
CONCLUSIONS
SARS-CoV2 virus infection preventive measures may be impacting the presentation of post-infectious diseases such as GBS. We did not observe an increase in GBS cases during 2020. Also, the AIDP variant were more frequent in our population in the COVID-19 pandemic.
