Results 51% of participants who contracted COVID-19 (N=43) experienced symptoms ≥28 days and were classified as having post-COVID syndrome [...]

Interpretation Our results contradict the perception that this “yet to be defined” post-COVID syndrome predominantly affects middle-aged adults and suggest that exercise intolerance, dyspnea, chest pain, chemosensory impairment, lymphadenopathy, rhinitis, and appetite loss may differentiate post-COVID syndrome from general symptoms of pandemic, age, and academic related stress. These findings are also consistent with previous reports that females are more vulnerable to this post viral syndrome. Large-scale population-based studies are essential to discerning the magnitude and characterization of post-COVID syndrome in young adults as well as more diverse populations.

Diagnosis
A diagnosis of COVID-19 can either be done on a clinical basis or through positive laboratory findings:


 * WHO COVID-19: Case Definitions


 * ICD-10: The International Classification of Diseases

U07.2 COVID-19, virus not identified

Use this code when COVID-19 is diagnosed clinically or epidemiologically but laboratory testing is inconclusive or not available.


 * NHSE National Guidance for post-COVID syndrome assessment clinics

1. Purpose

The purpose of this document is to provide commissioning guidance on the development of a specification to assist local healthcare systems to establish post-COVID assessment clinics for patients experiencing long-term health effects following COVID-19 infection. Clinics will offer physical, cognitive and psychological assessments with the aim of providing consistent post-COVID syndrome services for all who need them, whether they were hospitalised or not and regardless of whether clinically diagnosed or by a SARS-CoV2 test.

Abstract Coronavirus disease 2019 (COVID-19) is caused by severe acute respiratory syndrome coronavirus 2. We report a case of new-onset postural orthostatic tachycardia syndrome in an otherwise healthy female patient following COVID-19 infection. The patient presented with fatigue, orthostatic palpitations, dizziness, and presyncope. She underwent head-up tilt-table testing and the findings were suggestive of postural orthostatic tachycardia syndrome.

Conclusion ''Autonomic dysfunction presenting as POTS can be a delayed manifestation of COVID-19 infection. A high index of suspicion in post–COVID-19 patients who present with orthostatic symptoms may lead to proper diagnosis and treatment in such patients.''

Abstract The SARS-CoV-2 (COVID-19) pandemic has caused unprecedented morbidity, mortality and global disruption. Following the initial surge of infections, focus shifted to managing the longer-term sequelae of illness in survivors. ''‘Post-acute COVID’ (known colloquially as ‘long COVID’) is emerging as a prevalent syndrome. It encompasses a plethora of debilitating symptoms (including breathlessness, chest pain, palpitations and orthostatic intolerance) which can last for weeks or more following mild illness. We describe a series of individuals with symptoms of ‘long COVID’, and we posit that this condition may be related to a virus- or immune-mediated disruption of the autonomic nervous system resulting in orthostatic intolerance syndromes. We suggest that all physicians should be equipped to recognise such cases, appreciate the symptom burden and provide supportive management. We present our rationale for an underlying impaired autonomic physiology post-COVID-19 and suggest means of management.''

MCAS and histamine intolerance
Lawrence B. Afrin, Leonard B. Weinstock, Gerhard J. Molderings Covid-19 hyperinflammation and post-Covid-19 illness may be rooted in mast cell activation syndrome International Journal of Infectious Diseases, Volume 100, 2020, Pg 327-332, ISSN 1201-9712. doi: 10.1016/j.ijid.2020.09.016

Highlights
 * Much of Covid-19 hyperinflammation is consistent with mast-cell-driven inflammation.
 * Prevalence of severe Covid-19 is similar to that of mast cell activation syndrome (MCAS).
 * Drugs inhibiting mast cells (MCs) and their mediators show promise in Covid-19.
 * None of the authors currently treated MCAS patients with Covid-19 had severe forms or mortality.
 * The dysfunctional MCs of MCAS may underlie severe acute and chronic Covid-19 illness.

Abstract Objectives One-fifth of Covid-19 patients suffer a severe course of Covid-19 infection; however, the specific causes remain unclear. Mast cells (MCs) are activated by SARS-CoV-2. Although only recently recognized, MC activation syndrome (MCAS), usually due to acquired MC clonality, is a chronic multisystem disorder with inflammatory and allergic themes, and an estimated prevalence of 17%. This paper describes a novel conjecture explaining how MCAS might cause a propensity for severe acute Covid-19 infection and chronic post-Covid-19 illnesses.

Methods Observations of Covid-19 illness in patients with/without MCAS were compared with extensive clinical experience with MCAS.

Results The prevalence of MCAS is similar to that of severe cases within the Covid-19-infected population. Much of Covid-19’s hyperinflammation is concordant with manners of inflammation which MC activation can drive. Drugs with activity against MCs or their mediators have preliminarily been observed to be helpful in Covid-19 patients. None of the authors’ treated MCAS patients with Covid-19 suffered severe infection, let alone mortality.

Conclusions Hyperinflammatory cytokine storms in many severely symptomatic Covid-19 patients may be rooted in an atypical response to SARS-CoV-2 by the dysfunctional MCs of MCAS rather than a normal response by normal MCs. If proven, this theory has significant therapeutic and prognostic implications.
