ABSTRACT

OBJECTIVES: To describe the characteristics, evolution and risk factors for long-term persistence of olfactory and gustatory dysfunctions (OGD) in COVID-19 outpatients. PATIENTS AND METHODS: We conducted a prospective study in SARS-CoV-2 infected outpatients with OGD. Weekly phone interviews were set up starting from COVID-19 onset symptoms and over the course of 60 days, using standardized questionnaires that included a detailed description of general symptoms and OGD. The primary outcome was the proportion of patients with complete recovery of OGD at D30. Rate and time to recovery of OGD, as well as risk factors for late recovery (>30 days), were evaluated using Cox regression models. RESULTS: Ninety-eight outpatients were included. The median time to onset of OGD after first COVID-19 symptoms was 2 days (IQR 0-4). The 30-day recovery rate from OGD was 67.5% (95% CI 57.1-75.4) and the estimated median time of OGD recovery was 20 days (95% CI 13-26). Risk factors for late recovery of OGD were a complete loss of smell or taste at diagnosis (HR=0.26, 95% CI 0.12-0.56, P=0.0005) and age over 40 years (HR=0.56, 95% CI 0.36-0.89, P=0.01). CONCLUSIONS: COVID-19 patients with complete loss of smell or taste and over age 40 are more likely to develop persistent OGD and should rapidly receive sensorial rehabilitation.

ABSTRACT

AIM: The aim of this paper is to describe the clinical features of COVID-19-related encephalopathy and their metabolic correlates using brain 2-desoxy-2-fluoro-D-glucose (FDG)-positron-emission tomography (PET)/computed tomography (CT) imaging. BACKGROUND AND PURPOSE: A variety of neurological manifestations have been reported in association with COVID-19. COVID-19-related encephalopathy has seldom been reported and studied. METHODS: We report four cases of COVID-19-related encephalopathy. The diagnosis was made in patients with confirmed COVID-19 who presented with new-onset cognitive disturbances, central focal neurological signs, or seizures. All patients underwent cognitive screening, brain magnetic resonance imaging (MRI), lumbar puncture, and brain 2-desoxy-2-fluoro-D-glucose (FDG)-positron-emission tomography (PET)/computed tomography (CT) (FDG-PET/CT). RESULTS: The four patients were aged 60 years or older, and presented with various degrees of cognitive impairment, with predominant frontal lobe impairment. Two patients presented with cerebellar syndrome, one patient had myoclonus, one had psychiatric manifestations, and one had status epilepticus. The delay between first COVID-19 symptoms and onset of neurological symptoms was between 0 and 12 days. None of the patients had MRI features of encephalitis nor significant cerebrospinal fluid (CSF) abnormalities. SARS-CoV-2 RT-PCR in the CSF was negative for all patients. All patients presented with a consistent brain FDG-PET/CT pattern of abnormalities, namely frontal hypometabolism and cerebellar hypermetabolism. All patients improved after immunotherapy. CONCLUSIONS: Despite varied clinical presentations, all patients presented with a consistent FDG-PET pattern, which may reflect an immune mechanism.

ABSTRACT

Introduction Bien que les manifestations neurologiques associées à l’infection par SARS-CoV-2 soient de plus en plus rapportées, peu de données sont disponibles sur leurs caractéristiques cliniques et leur pronostic. Matériels et méthodes Nous avons mené une étude observationnelle rétrospective multicentrique afin de décrire les manifestations neurologiques associées à l’infection par SARS-CoV-2 pendant la vague épidémique en France en mars et avril 2020. Nous avons inclus des patients COVID-19 ayant des symptômes neurologiques de novo survenant en relation temporelle étroite avec les autres symptômes de la maladie. Résultats Nous avons inclus 222 patients NeuroCOVID provenant de 46 centres de différentes régions françaises. L’âge médian était de 65 ans (IQR 53–72) et 136 patients (61,3 %) étaient des hommes. La maladie COVID-19 était sévère ou réanimatoire pour près de la moitié des patients (102, 45,2 %). Des atteintes du système nerveux central étaient rapportées pour 189 patients (85,1 %) et des atteintes du système nerveux périphérique pour 29 patients (13,1 %). Les symptômes neurologiques les plus fréquents étaient une altération de l’état mental (117, 52,4 %) et un déficit neurologique focal central (97, 43,7 %). Une imagerie cérébrale a été réalisée chez 192 patients (86,5 %), dont 157 IRM (70,7 %), et montrait des lésions aiguës dans 85/192 cas (44,3 %). Parmi les 97 examens du liquide céphalorachidien (LCR), une pléiocytose était présente chez 18 patients (18,6 %) et la PCR SARS-CoV-2 était positive dans 2 des 75 LCR testés (2,7 %). Le suivi médian était de 24jours et le taux de mortalité était de 12,6 %. Sur l’ensemble des manifestations neurologiques associées au COVID-19, nous décrivons 67 patients avec encéphalopathie associée au COVID, 21 patients avec encéphalite, 57 patients avec accident ischémique cérébral et 15 patients avec syndrome de Guillain-Barré. Conclusion Il s’agit à notre connaissance de la plus large série de patients neuroCOVID actuellement publiée au monde. Elle met en évidence le spectre très large des différentes manifestations neurologiques liées au COVID-19, avec au premier plan encéphalopathies et accidents ischémiques cérébraux, et dans une moindre mesure, encéphalites et syndromes de Guillain-Barré.
