Many studies have investigated post-COVID symptoms, but the predictors of symptom persistence remain unknown. The objective was to describe the natural course of the disease at 6 months and to identify possible factors favoring the resurgence or persistence of these symptoms. COVEVOL is a retrospective observational descriptive study of 74 patients. All patients with positive SARS-CoV-2 PCR from March 2020 were included. We compared a group with symptom persistence (PS group) with another group without symptom persistence (no-PS group). Fifty-three out of seventy-four patients (71.62%) described at least one persistent symptom at 6 months of SARS-CoV-2 infection. In the PS group, 56.6% were women and the average age was 54.7 years old [21-89.2] ±16.9. The main symptoms were asthenia (56.6%, n = 30), dyspnea (34%, n = 18), anxiety (32.1% n = 17), anosmia (24.5%, n = 13) and agueusia (15.1% n = 8). Ten patients (13.51%) presented a resurgence in symptoms. Patients in the PS group were older (p = 0.0048), had a higher BMI (p = 0.0071), and were more frequently hospitalized (p = 0.0359) compared to the no-PS group. Odynophagia and nasal obstruction were less present in the inaugural symptoms of COVID-19 in the PS group (p = 0.0202 and p = 0.0332). Persistent post-COVID syndromes are common and identification of contributing factors is necessary for understanding this phenomenon and appropriate management.

IntroductionPersistent chest pain (PCP) following acute COVID‐19 infection is a commonly reported symptom with an unclear etiology, making its management challenging. This scoping review aims to address the knowledge gap surrounding the characteristics of PCP following COVID‐19, its causes, and potential treatments.ObjectiveTo assess the prevalence, causes, and potential treatments of PCP following COVID‐19 infection.DesignA scoping review of 64 studies, including observational (prospective, retrospective, cross‐sectional, case series, and case‐control) and one quasi‐experimental study, from databases including Embase, PubMed/MEDLINE, Cochrane CENTRAL, Google Scholar, Cochrane Database of Systematic Reviews, and Scopus.SettingStudies on patients with PCP following mild, moderate, and severe COVID‐19 infection.PatientsStudies that included patients of any age, with chest pain that persisted following acute COVID‐19 disease, irrespective of etiology or duration.InterventionsNot applicable.Main Outcome Measure(s)Prevalence, causes, and potential treatments of PCP following COVID‐19 infection.ResultsA total of 35 studies reported PCP symptoms following COVID‐19 (0.24‐76.6%) at an average follow‐up of three months or longer, 12 studies at 1‐3 months and 17 studies at less than one month follow‐up or not specified. PCP was common following mild ‐ severe COVID‐19 infection, and etiology was mostly not reported. Fourteen studies proposed potential etiologies including endothelial dysfunction, cardiac ischemia, vasospasm, myocarditis, cardiac arrhythmia, pneumonia, pulmonary embolism, postural tachycardia syndrome (POTS), or noted cardiac MRI (cMRI) changes. Evaluation methods included common cardiopulmonary tests, as well as less common tests such as flow‐mediated dilatation (FMD), cMRI, single‐photon emission computed tomography myocardial perfusion imaging (SPECT‐MPI), and cardiopulmonary exercise testing (CPET). Only one study reported a specific treatment (sulodexide).ConclusionsPCP is a prevalent symptom following COVID‐19 infection, with various proposed etiologies. Further research is needed to establish a better understanding of the causes and to develop targeted treatments for PCP following COVID‐19.This article is protected by copyright. All rights reserved.
Hintergrund In den letzten 2 Jahren der COVID-19(„coronavirus disease 2019“)-Pandemie ist das Wissen um Langzeitfolgen der Erkrankung, das sog. „Long-COVID“, rapide gewachsen. Es bleiben jedoch noch viele Fragen offen, v. a. was die Ursachen überdauernder Beschwerden und ihre Prognose betrifft. Kognitive Störungen und Schlafstörungen gehören zu den häufig beklagten Beschwerden. Beide gehen mit starkem Leidensdruck und deutlicher Alltagsbeeinträchtigung einher. Ziel der Arbeit Wie ist die Datenlage zum Auftreten kognitiver Störungen und Schlafstörungen bei Long-COVID? Welches sind Einflussfaktoren und was ist bekannt zum Verlauf und zu möglichen zugrunde liegenden Mechanismen? Welche Therapieoptionen gibt es? Material und Methode In einem narrativen Review werden die wichtigsten Befunde zu kognitiven Störungen und Schlafstörungen bei Long-COVID dargestellt. Es wird ein Überblick gegeben über die Kohortenstudien mit Daten zu Prävalenz und Einflussfaktoren beider Symptomkomplexe. Es werden derzeitige Kenntnisse und Hypothesen zu pathophysiologischen Mechanismen dargestellt und ein Ausblick auf Behandlungsansätze gegeben. Ergebnisse Etwa ein Fünftel der Betroffenen berichtet mehr als 3 Monate nach einer SARS-CoV-2(„severe acute respiratory syndrome coronavirus 2“)-Infektion über kognitive Einschränkungen, etwa ein Drittel über Schlafstörungen, wobei es neben insomnischen auch zu hypersomnische Beschwerden kommt. Kognitive Störungen und Schlafstörungen treten bei Betroffenen aller Schweregrade auf. Es gibt Hinweise auf eine Besserung kognitiver Defizite im Verlauf, allerdings sind weitere Längsschnittstudien notwendig. Diskussion Neben der Prognose sind die zugrunde liegenden Krankheitsmechanismen noch unzureichend verstanden. Zudem besteht großer Forschungsbedarf zur Wirksamkeit und zu spezifischen Wirkfaktoren therapeutischer Interventionen .
