Neuro-COVID-19

Abstract:

Neuromuscular manifestations of new coronavirus disease 2019 (COVID-19) infection are frequent, and include dizziness, headache, myopathy, and olfactory and gustatory disturbances. Patients with acute central nervous system disorders, such as delirium, impaired consciousness, stroke and convulsive seizures, have a high mortality rate.

The encephalitis/encephalopathy that causes consciousness disturbance and seizures can be classified into three conditions, including direct infection with the SARS-CoV-2 virus, encephalopathy caused by central nervous system damage secondary to systemic hypercytokinemia (cytokine storm) and autoimmune-mediated encephalitis that occurs after infection.

The sequelae, called post-acute COVID-19 syndrome or long COVID, include neuromuscular manifestations, such as anxiety, depression, sleep disturbance, muscle weakness, brain fog and cognitive impairment. It is desirable to establish diagnostic criteria and treatment for these symptoms. Vaccine-induced thrombotic thrombocytopenia, Guillain-Barré syndrome, bilateral facial paralysis, encephalitis and opsoclonus-myoclonus syndrome have been reported as adverse reactions after the COVID-19 vaccine, although these are rare.

Persistence of Symptoms After Discharge of Patients Hospitalized Due to COVID-19

Abstract:

Many patients who had coronavirus disease 2019 (COVID-19) had at least one symptom that persisted after recovery from the acute phase. Our purpose was to review the empirical evidence on symptom prevalence, complications, and management of patients with long COVID. We systematically reviewed the literature on the clinical manifestations of long COVID-19, defined by the persistence of symptoms beyond the acute phase of infection. Bibliographic searches in PubMed and Google Scholar were conducted to retrieve relevant studies on confirmed patients with long COVID that were published prior to August 30, 2021.

The most common persistent symptoms were fatigue, cough, dyspnea, chest pains, chest tightness, joint pain, muscle pain, loss of taste or smell, hair loss, sleep difficulties, anxiety, and depression. Some of the less common persistent symptoms were skin rash, decreased appetite, sweating, inability to concentrate, and memory lapses. In addition to these general symptoms, some patients experienced dysfunctions of specific organs, mainly the lungs, heart, kidneys, and nervous system.

A comprehensive understanding of the persistent clinical manifestations of COVID-19 can improve and facilitate patient management and referrals. Prompt rehabilitative care and targeted interventions of these patients may improve their recovery from physical, immune, and mental health symptoms.

Incidence and risk factors of long COVID in the UK: a single-centre observational study

Abstract:

Background: Studies to evaluate long COVID symptoms and their risk factors are limited. We evaluated the presence of long COVID and its risk factors in patients discharged from a hospital with COVID-19 illness.

Methods: This observational study included 271 COVID-19 patients admitted between February and July 2020 in a hospital in the UK. The primary outcome measure was to assess the duration and severity of long COVID and its predictors at 3, 6 and 9 months. Logistic regression was performed to assess the potential risk factors for long COVID.

Results: Out of 89 patients interviewed, 55 (62%) had long COVID for 3 months, 46 (52%) for 6 months and 37 of the 75 patients admitted to the hospital with acute COVID-19 had long COVID for 9 months (49%). The most common long COVID symptoms were fatigue and breathlessness.

Conclusion: Nearly two-thirds of patients at 3 months and a half at 9 months had long COVID. COVID-19 pneumonia was the strongest predictor of long COVID in Caucasians at 3 months.

Long COVID-The New “Invisible” Illness: How School Nurses Can Support the Nursing and Educational Teams for Student Success

Abstract:

School-age children are not immune to COVID-19 or the pronounced and persistent symptoms associated with a long-COVID diagnosis. Students may present with a variety of symptoms affecting their physical, cognitive, and mental health. The school community should be educated on the school-based interventions and recommendations for creating an individualized safe and successful return to school plan. As we await approval for vaccinations in school-age children younger than 12 years and continue to reposition ourselves to the waves of this pandemic and new variants of the virus, understanding the medical and educational long-term effects on our students may be a long-term need.

Proposed subtypes of post-COVID-19 syndrome (or long-COVID) and their respective potential therapies

Abstract:

The effects of coronavirus disease 2019 (COVID-19), a highly transmissible infectious respiratory disease that has initiated an ongoing pandemic since early 2020, do not always end in the acute phase. Depending on the study referred, about 10%-30% (or more) of COVID-19 survivors may develop long-COVID or post-COVID-19 syndrome (PCS), characterised by persistent symptoms (most commonly fatigue, dyspnoea, and cognitive impairments) lasting for 3 months or more after acute COVID-19. While the pathophysiological mechanisms of PCS have been extensively described elsewhere, the subtypes of PCS have not.

Owing to its highly multifaceted nature, this review proposes and characterises six subtypes of PCS based on the existing literature. The subtypes are non-severe COVID-19 multi-organ sequelae (NSC-MOS), pulmonary fibrosis sequelae (PFS), myalgic encephalomyelitis or chronic fatigue syndrome (ME/CFS), postural orthostatic tachycardia syndrome (POTS), post-intensive care syndrome (PICS) and medical or clinical sequelae (MCS). Original studies supporting each of these subtypes are documented in this review, as well as their respective symptoms and potential interventions. Ultimately, the subtyping proposed herein aims to provide better clarity on the current understanding of PCS.

Proposal of a food supplement for the management of post-COVID syndrome

Abstract:

A vast majority of COVID-19 patients experience fatigue, extreme tiredness and symptoms that persist beyond the active phase of the disease. This condition is called post-COVID syndrome. The mechanisms by which the virus causes prolonged illness are still unclear. The aim of this review is to gather information regarding post-COVID syndrome so as to highlight its etiological basis and the nutritional regimes and supplements that can mitigate, alleviate or relieve the associated chronic fatigue, gastrointestinal disorders and continuing inflammatory reactions. Naturally-occurring food supplements, such as acetyl L-carnitine, hydroxytyrosol and vitamins B, C and D hold significant promise in the management of post-COVID syndrome. In this pilot observational study, we evaluated the effect of a food supplement containing hydroxytyrosol, acetyl L-carnitine and vitamins B, C and D in improving perceived fatigue in patients who recovered from COVID-19 but had post-COVID syndrome characterized by chronic fatigue. The results suggest that the food supplement could proceed to clinical trials of its efficacy in aiding the recovery of patients with long COVID.

Spectrum of SARS-CoV-2-Related Clinical Syndromes in Children: A Year in the Life

Abstract:

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has a wide pediatric clinical spectrum. Initial reports suggested that children had milder symptoms compared with adults; then diagnosis of multisystem inflammatory syndrome in children (MIS-C) emerged. We performed a retrospective cohort study of hospitalized patients at a children’s hospital over 1 year. Our objectives were to study the demographic and clinical profile of pediatric SARS-CoV-2-associated diagnoses.

Based on the clinical syndrome, patients were classified into coronavirus disease 2019 (COVID-19; non-MIS-C) and MIS-C cohorts. Among those who tested positive, 67% were symptomatic. MIS-C was diagnosed in 24 patients. Both diagnoses were more frequent in Caucasians. Both cohorts had different symptom profiles.

Inflammatory markers were several-fold higher in MIS-C patients. These patients had critical care needs and longer hospital stays. More COVID-19 patients had respiratory complications, while MIS-C cohort saw cardiovascular involvement. Health care awareness of both syndromes is important for early recognition, diagnosis, and prompt treatment.

Reduced Parasympathetic Reactivation during Recovery from Exercise in Myalgic Encephalomyelitis/Chronic Fatigue Syndrome

Abstract:

Although autonomic nervous system (ANS) dysfunction in Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) has been proposed, conflicting evidence makes it difficult to draw firm conclusions regarding ANS activity at rest in ME/CFS patients. Although severe exercise intolerance is one of the core features of ME/CFS, little attempts have been made to study ANS responses to physical exercise. Therefore, impairments in ANS activation at rest and following exercise were examined using a case-control study in 20 ME/CFS patients and 20 healthy people.

Different autonomous variables, including cardiac, respiratory, and electrodermal responses were assessed at rest and following an acute exercise bout. At rest, parameters in the time-domain represented normal autonomic function in ME/CFS, while frequency-domain parameters indicated the possible presence of diminished (para)sympathetic activation. Reduced parasympathetic reactivation during recovery from exercise was observed in ME/CFS.

This is the first study showing reduced parasympathetic reactivation during recovery from physical exercise in ME/CFS. Delayed HR recovery and/or a reduced HRV as seen in ME/CFS have been associated with poor disease prognosis, high risk for adverse cardiac events, and morbidity in other pathologies, implying that future studies should examine whether this is also the case in ME/CFS and how to safely improve HR recovery in this population.

Small heart and single coronary artery in a young patient with chronic fatigue syndrome: a case report

Abstract:

Aims: Chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME) is a clinically defined condition reported mostly in adults, characterized by fatigue and unexplained aspecifical symptoms. Patients with CFS/ME frequently have reduced stroke volume with an inverse relation between cardiac output and post-exertional malaise severity. We describe a rare case of a young man affected by CFS/ME, small heart, and anomalous anatomy of left main coronary artery (LMCA).

Methods and results: A 19-year-old Caucasian male referred to our clinic complaining weakness, lack of concentration, and sleepiness. He suffered by CFS/ME, D hypovitaminosis, inflammatory bowel disease, and exocrine pancreas insufficiency.

Blood tests revealed no pathological findings. Faecal exams documented intestinal dysbiosis and low pancreatic elastase.

He was treated with oxygen-ozone rectal insufflations and probiotics. Physical examination was unremarkable.

Electrocardiogram showed normal sinus rhythm. Echocardiogram revealed reduced diameters of the left ventricle (LV), normal aortic root dimensions and, in a five-chamber apical view, a binary structure that seemed to cross the aorta perpendicularly. Cardiac magnetic resonance (CMR) found reduced LV stroke volume (34 ml/m2) and end-diastolic volume (57 ml/m2) together with reduced end-diastolic wall mass (51 g/m2). Right ventricle volumes were reduced too.

In addition, the exam confirmed the anomalous origin of LMCA stemming from the proximal segment of right coronary artery and following a retro-aortic course.

Mechanism of CFS/ME remains unknown, although various factors have been implicated, including immune activation, chronic viral infection, and emotional disorders.

A considerable number of patients affected by CFS has an anatomically small heart. Small heart syndrome, in fact, may contribute to the onset of CFS/ME.

Previous studies hypothesized that clinical manifestations of CMS/ME were caused by reduced venous return, cardiac output, and heart mass, together with decreased arterial oxygen saturation. Single coronary artery is an uncommon congenital anatomic abnormality identified by a single coronary ostium giving rise to all arteries supplying the heart.

Thus, we reported a rare case of a very young man affected by chronic fatigue syndrome and small heart, investigated not only with echocardiogram but also with CMR, not often used in this clinical setting. More, we found an anomalous origin of LMCA. From literature, it’s not reported any cases of a patient including these three rare conditions (CFS/ME, small heart, and single coronary artery).

Conclusions: This case highlights that CFS/ME together with small heart is a condition possible also in young people. More studies and reports could be necessary to better define the association between cardiac congenital anomalies and CFS/ME.

Characterizing long COVID in an international cohort: 7 months of symptoms and their impact

Abstract:

Background: A significant number of patients with COVID-19 experience prolonged symptoms, known as Long COVID. Few systematic studies have investigated this population, particularly in outpatient settings. Hence, relatively little is known about symptom makeup and severity, expected clinical course, impact on daily functioning, and return to baseline health.

Methods: We conducted an online survey of people with suspected and confirmed COVID-19, distributed via COVID-19 support groups (e.g. Body Politic, Long COVID Support Group, Long Haul COVID Fighters) and social media (e.g. Twitter, Facebook). Data were collected from September 6, 2020 to November 25, 2020. We analyzed responses from 3762 participants with confirmed (diagnostic/antibody positive; 1020) or suspected (diagnostic/antibody negative or untested; 2742) COVID-19, from 56 countries, with illness lasting over 28 days and onset prior to June 2020. We estimated the prevalence of 203 symptoms in 10 organ systems and traced 66 symptoms over seven months. We measured the impact on life, work, and return to baseline health.

Findings: For the majority of respondents (>91%), the time to recovery exceeded 35 weeks. During their illness, participants experienced an average of 55.9+/- 25.5 (mean+/-STD) symptoms, across an average of 9.1 organ systems. The most frequent symptoms after month 6 were fatigue, post-exertional malaise, and cognitive dysfunction. Symptoms varied in their prevalence over time, and we identified three symptom clusters, each with a characteristic temporal profile. 85.9% of participants (95% CI, 84.8% to 87.0%) experienced relapses, primarily triggered by exercise, physical or mental activity, and stress. 86.7% (85.6% to 92.5%) of unrecovered respondents were experiencing fatigue at the time of survey, compared to 44.7% (38.5% to 50.5%) of recovered respondents. 1700 respondents (45.2%) required a reduced work schedule compared to pre-illness, and an additional 839 (22.3%) were not working at the time of survey due to illness. Cognitive dysfunction or memory issues were common across all age groups (~88%). Except for loss of smell and taste, the prevalence and trajectory of all symptoms were similar between groups with confirmed and suspected COVID-19.

Interpretation: Patients with Long COVID report prolonged, multisystem involvement and significant disability. By seven months, many patients have not yet recovered (mainly from systemic and neurological/cognitive symptoms), have not returned to previous levels of work, and continue to experience significant symptom burden.
