BACKGROUND

During the Coronavirus disease 2019 (COVID-19) pandemic, different neurological manifestations have been observed. However, only a few cases of Guillain-Barre syndrome (GBS) and COVID-19 have been reported. Therefore, the aim of this study is to investigate a case of concomitant GBS with COVID-19 in Colombia.

CASE PRESENTATION

A 39-year-old woman was admitted to a teaching hospital in Barranquilla, Colombia with a history of progressive general weakness with lower limb dominance. Previous symptoms such as ageusia, anosmia and intense headache were reported. Upon admission, facial diplegia, quadriparesis with lower extremity predominance and Medical Research Council muscular strength of 2/5 in the lower limbs and 4/5 in the upper limbs were reported. During clinical evolution, due to general areflexia, hypertensive emergency and progressive diaphragmatic weakness, the patient was admitted to an intensive care unit. The cerebrospinal fluid analysis showed protein-cytological dissociation and the GBS diagnosis was confirmed via a nerve conduction and electromyography test. With regard to the symptoms before hospitalisation, SARS-CoV-2 diagnostic testing was performed with positive results in the second test. The patient was managed with supportive care and was discharged after 20 days of hospitalization with clinical improvement.

CONCLUSIONS

Only a few cases of COVID-19 with GBS have been reported. Different subtypes have been previously identified, such as Miller-Fisher syndrome and dysautonomic GBS with SARS-CoV-2 infection. This study investigated the first confirmed case of COVID-19 with concomitant GBS in Colombia. In patients with GBS, several viral and bacterial pathogens have been found in case-control studies but the factors that induce the immune-mediated destruction of the nerve tissues have not been determined. Further studies are needed to determine the possible association between COVID-19 exposure and GBS.

Coronavirus disease 2019 (COVID-19) has high infectivity and causes extensive morbidity and mortality. Cardiovascular disease is a risk factor for adverse outcomes in COVID-19, but baseline left ventricular ejection fraction (LVEF) in particular has not been evaluated thoroughly in this context. We analyzed patients in our state's largest health system who were diagnosed with COVID-19 between March 20 and May 15, 2020. Inclusion required an available echocardiogram within 1 year prior to diagnosis. The primary outcome was all-cause mortality. LVEF was analyzed both as a continuous variable and using a cutoff of 40%. Among 396 patients (67 ± 16 years, 191 [48%] male, 235 [59%] Black, 59 [15%] LVEF ≤40%), 289 (73%) required hospital admission, and 116 (29%) died during 85 ± 63 days of follow-up. Echocardiograms, performed a median of 57 (IQR 11-122) days prior to COVID-19 diagnosis, showed a similar distribution of LVEF between survivors and decedents (P = 0.84). Receiver operator characteristic analysis revealed no predictive ability of LVEF for mortality, and there was no difference in survival among those with LVEF ≤40% versus >40% (P = 0.49). Multivariable analysis did not change these relationships. Similarly, there was no difference in LVEF based on whether the patient required hospital admission (56 ± 13 vs 55 ± 13, P = 0.38), and patients with a depressed LVEF did not require admission more frequently than their preserved-LVEF peers (P = 0.87). A premorbid history of dyspnea consistent with symptomatic heart failure was not associated with mortality (P = 0.74). Among patients diagnosed with COVID-19, pre-COVID-19 LVEF was not a risk factor for death or hospitalization.
