ABSTRACT

Background: COVID-19 may be a new risk factor for stroke. Stroke in COVID-19 varies from 1.1 to 8.1%. Various pathophysiological pathways predispose SARS-CoV-2 infected patients to stroke. Aim: To describe COVID-19 patients with acute stroke in one Colombian Center. Methods: From March 6 2020 and March 6 2021 records of patients with acute stroke and in-hospital positive PCR (Polymerase Chain Reaction) test for Sars-CoV-2 infection were reviewed. Demographic, stroke and COVID-19 characteristics were extracted. Continuous variables were reported in means and ranges. Categorical variables were presented in frequencies and percentage. A descriptive narrative was performed. Results: Of 328 acute stroke patients 14 (4.2%) tested positive for PCR SARS-CoV-2. Mean age 56.4 years with 57% males. Five were (35.7%) without vascular risk factors but 9 (64.3%) overweight. Brain infarct diagnosed in 11 (78.5%), 53% with anterior circulation syndromes. Mean NIHSS score 11.8 and 7 (63%) received intravenous thrombolysis. Acute inflammatory blood biomarkers (D-dimer, ferritin, LDH elevated) were positive in all. 11 (78.5%) had symptomatic COVID-19 before stroke with a mean latency of 7 days. 12 (85.7%) had severe COVID-19 and 6 (42.8%) required mechanical ventilation. Outcome was unfavorable in 9 (64.3%) (The Modified Rankin Scale (mRS) > 2), mean hospital stay was 21.8 days and in-hospital case fatality rate was 14.2%. Conclusion: In susceptible individuals COVID-19 predisposes to stroke. Hypercoagulation and immune thrombosis may be at the culprit for this state. In Colombia, COVID-19 patients with stroke have similar characteristics to the described worldwide.

ABSTRACT

SARS-CoV-2 infection has been associated with multiple neurological manifestations. One such manifestation, which has been described since the early stages of the COVID-19 pandemic and is relevant for current neurological practice, is Guillain-Barré syndrome (GBS). The literature describes neurotoxic mechanisms of the virus itself and the possible pathways by which it may affect the peripheral nerves in experimental studies; however, we still lack information on the mechanisms causing the immune response that gives rise to GBS in the context of SARS-CoV-2 infection. Colombia is one of the Latin American countries worst affected by the pandemic, with the third-highest number of cases in the region; thus, it is essential to recognise GBS, as this potential postinfectious complication may severely compromise the patient's functional status in the absence of timely diagnosis and treatment. We present a series of 12 cases of GBS associated with SARS-CoV-2 infection from hospitals in 4 different Colombian cities and describe the clinical presentation, laboratory and electrophysiological study findings, and treatment.


En el año 2020 se declaro la pandemia ocasionada por la infección por el virus SARSCoV-2, virus de la familia del coronavirus, adoptándose el nombre de COVID-19 a la enfermedad 1. En Bogotá, Colombia, se confirmó el primer caso de COVID-19 el 6 de marzo de 2020 (2). Los principales síntomas reportados en la infección por SARSCoV-2 son fiebre (43.8% en la admisión y 88.7% durante la hospitalización) y tos (67.8%) (3). Otros síntomas encontrados son fatiga (38.1%), producción de esputo (33.7%) y cefalea (13.6%). Los principales signos neurológicos reportados en los pacientes con infección severa por SARS-Cov-2 son agitación (69%), compromiso en tracto corticoespinal (67%) y delirium (65%) (4). Las principales complicaciones neurológicas descritas asociadas a Covid 19 son: anosmia, disgeusia, encefalopatia, Síndrome de Guillain Barre, complicaciones cerebrovasculares y daño en musculo esquelético (5­8).En el presente articulo se presenta una serie de casos de pacientes con síndrome de Guillain-Barré asociado a infección por SARS-CoV-2. Se recolectaron casos de diferentes instituciones medicas de Colombia.
