Molecular mimicry in the post-COVID-19 signs and symptoms of neurovegetative disorders?
2021
Many individuals who have severe forms of COVID-19 experience a suite of neurovegetative signs and symptoms (eg, tachycardia) after their recovery, suggesting that the imbalance of the sympathetic-parasympathetic activity of the autonomic nervous system1 could continue for many weeks or months after respiratory symptoms stop. Moreover, a reduction of the parasympathetic tone could have a role in restricting the cholinergic anti-inflammatory pathway, thus favouring hyperinflammation and cytokine storm in the most severe phases of the disease. As reported by Guglielmo Lucchese in The Lancet Microbe,2 SARS-CoV-2 can damage the nervous system via an indirect mechanism, resulting in a high preva…

Oral antiseptics against coronavirus: in-vitro and clinical evidence
2021
Background Angiotensin converting enzyme II (ACE2) is the cellular receptor for SARS-CoV-2, so ACE2-expressing cells can act as target cells and are susceptible to infection. ACE2 receptors are highly expressed in the oral cavity so this may be a potential high-risk route for SARS-CoV-2 infection. Furthermore, the virus can be detected in saliva, even before COVID-19 symptoms appear, with the consequent high risk of virus transmission in asymptomatic/pre-symptomatic patients. Reducing oral viral load could lead to a lower risk of transmission via salivary droplets or aerosols and therefore contribute to the control of the pandemic. Aim To evaluate the available evidence testing the in vitro…
Initial viral load and decay kinetics of SARS-CoV-2 lineage B.1.1.7 in the upper respiratory tract of adults and children
2021
We read with interest the systematic review published by Walsh et al. in the Journal of Infection,1 focusing on the dynamics of SARS-CoV-2 RNA at the upper respiratory tract (URT). In this context, a novel SARS-CoV-2 variant lineage (B.1.1.7), first detected in the UK at the end of 2020 has transmission advantage over other lineages.2 Increased transmissibility of the B.1.1.7 variant has been linked to enhanced ACE2 affinity3 allegedly resulting in higher viral loads in URT, an observation that has been reported in some,3, 4, 5, 6 but not all7 large series published to date. In addition, longer duration of SARS-CoV-2 RNA shedding in URT has been reported in individuals infected by the B.1.1…
Containment of a Large SARS-CoV-2 Outbreak Among Healthcare Workers in a Pediatric Intensive Care Unit.
2020
Objective Healthcare workers (HCWs) are particularly exposed SARS-CoV-2 because they are critical in preventing viral transmission and treating COVID-19 patients. Within HCWs, personnel of intensive care units (ICUs) are at the forefront of treating patients with a severe course of COVID-19 infection and therefore represent an extremely vulnerable group. Thus, our objective is to contribute to establish means of infection control protecting HCWs in the frontline of the current pandemic. Design An outbreak of SARS-CoV-2 was detected and contained in a pediatric ICU (PICU). The first positive case was identified with a point-of-care diagnostic system on site. Real-time PCR-based testing syste…
