Prevalence and risk factor for long COVID in children and adolescents: A meta-analysis and systematic review

Abstract:

Background: Millions of COVID-19 pediatric survivors are facing the risk of long COVID after recovery from acute COVID-19. The primary objective of this study was to systematically review the available literature and determine the pooled prevalence of, and risk factors for long COVID among the pediatric survivors.

Methods: Studies that assessed the prevalence of, or risk factors associated with long COVID among pediatric COVID-19 survivors were systematically searched in PubMed, Embase, Cochrane Library, medRxiv and bioRxiv up to December 11th, 2022. Random effects model was performed to estimate the pooled prevalence of long COVID among pediatric COVID-19 patients. Subgroup analyses and meta-regression on the estimated prevalence of long COVID were performed by stratification with follow-up duration, mean age, sex ratio, percentage of multisystem inflammatory syndrome, hospitalization rate at baseline, and percentage of severe illness.

Results: Based on 40 studies with 12,424 individuals, the pooled prevalence of any long COVID was 23.36% ([95% CI 15.27-32.53]). The generalized symptom (19.57%, [95% CI 9.85-31.52]) was reported most commonly, followed by respiratory (14.76%, [95% CI 7.22-24.27]), neurologic (13.51%, [95% CI 6.52-22.40]), and psychiatric (12.30%, [95% CI 5.38-21.37]). Dyspnoea (22.75%, [95% CI 9.38-39.54]), fatigue (20.22%, [95% CI 9.19-34.09]), and headache (15.88%, [95% CI 6.85-27.57]) were most widely reported specific symptoms. The prevalence of any symptom during 3-6, 6-12, and >12 months were 26.41% ([95% CI 14.33-40.59]), 20.64% ([95% CI 17.06-24.46]), and 14.89% ([95% CI 6.09-26.51]), respectively. Individuals with aged over ten years, multisystem inflammatory syndrome, or had severe clinical symptoms exhibited higher prevalence of long COVID in multi-systems. Factors such as older age, female, poor physical or mental health, or had severe infection or more symptoms were more likely to have long COVID in pediatric survivors.

Conclusions: Nearly one quarter of pediatric survivors suffered multisystem long COVID, even at 1 year after infection. Ongoing monitoring, comprehensive prevention and intervention is warranted for pediatric survivors, especially for individuals with high risk factors.

High Prevalence of Alternative Diagnoses in Children and Adolescents with Suspected Long COVID-A Single Center Cohort Study

Abstract:

Background: Long COVID (LC) is a diagnosis that requires exclusion of alternative somatic and mental diseases. The aim of this study was to examine the prevalence of differential diagnoses in suspected pediatric LC patients and assess whether adult LC symptom clusters are applicable to pediatric patients.

Materials and methods: Pediatric presentations at the Pediatric Infectious Diseases Department of the University Hospital Essen (Germany) were assessed retrospectively. The correlation of initial symptoms and final diagnoses (LC versus other diseases or unclarified) was assessed. The sensitivity, specificity, negative and positive predictive values of adult LC symptom clusters were calculated.

Results: Of 110 patients, 32 (29%) suffered from LC, 52 (47%) were diagnosed with alternative somatic/mental diseases, and 26 (23%) remained unclarified. Combined neurological and respiratory clusters displayed a sensitivity of 0.97 (95% CI 0.91-1.00) and a negative predictive value of 0.97 (0.92-1.00) for LC.

Discussion/conclusions: The prevalence of alternative somatic and mental diseases in pediatric patients with suspected LC is high. The range of underlying diseases is wide, including chronic and potentially life-threatening conditions. Neurological and respiratory symptom clusters may help to identify patients that are unlikely to be suffering from LC.

Mental health among children with long COVID during the COVID-19 pandemic

Abstract:

A growing number of studies report that persons of all ages, infected with SARS-CoV-2, may experience long-term persistent symptoms, known as long COVID (LC) or post COVID-19 condition. This is one of the first studies examining the consequences of LC on children’s mental health. In this case-control study, we compared select mental health aspects of 103 children diagnosed with LC to a control group of 113 children uninfected with SARS-COV-2; all 4-18 years old. Both groups were assessed via parents’ questionnaires.

In comparison to the control group, children with LC exhibited more memory difficulties. However, no group differences emerged in other functional aspects (connection with friends and engagement in physical activities), problems with concentration, or levels of emotional-behavioral problems (externalizing, internalizing, ADHD, and PTSD symptoms).

We also found that children with LC had greater exposure to COVID-19-related stressors. Higher levels of parental worries regarding their children’s functioning and economic difficulties at home significantly predicted higher levels of children’s emotional-behavioral problems and were better predictors than the child’s age, social functioning, or LC diagnosis.

Conclusion: LC was associated with impairments in some aspects of children’s memory which may relate to academic functioning, but not with higher rates of emotional-behavioral problems, thus warranting interventional programs addressing school functioning and cognitive abilities in this population. Additionally, parents’ economic stress and worries regarding their child’s emotional adjustment during the pandemic, are important factors affecting pandemic-related emotional-behavioral problems among children, regardless of COVID-19 infection, that should be addressed.

What is Known:

• Children may have long COVID (LC) after being infected with SARS-COV-2.

What is New:

• LC may be associated to impairments in some aspects of children’s memory, as reported by parents.

• Parents’ economic stress and worries concerning their children’s emotional adjustment during the pandemic are associated with more distress in their children.

Therapeutic Approaches to Dysautonomia in Childhood, with a Special Focus on Long COVID

Abstract:

Background: Dysautonomia seems to be important for the pathophysiology of psychosomatic diseases and, more recently, for long COVID. This concept may explain the clinical symptoms and could help open new therapeutic approaches.
Methods: We compared our data from an analysis of heart rate variability (HRV) in an active standing test in 28 adolescents who had developed an inappropriate sinus tachycardia (IST, n = 13) or postural orthostatic tachycardia syndrome (POTS, n = 15) after contracting COVID-19 disease and/or vaccination with 64 adolescents from our database who developed dysautonomia due to psychosomatic diseases prior to the COVID-19 pandemic. We prove the effects of our treatment: omega-3 fatty acid supplementation (O3-FA, n = 18) in addition to propranolol (low dose, up to 20-20-0 mg, n = 32) or ivabradine 5-5-0 mg (n = 17) on heart rate regulation and heart rate variability (HRV).
Results: The HRV data were not different between the adolescents with SARS-CoV-2-related disorders and the adolescents with dysautonomia prior to the pandemic. The heart rate increases in children with POTS while standing were significantly lower after low-dose propranolol (27.2 ± 17.4 bpm***), ivabradine (23.6 ± 8.12 bpm*), and O-3-FA (25.6 ± 8.4 bpm*). The heart rate in children with IST while lying/standing was significantly lower after propranolol (81.6 ± 10.1 bpm**/101.8 ± 18.8***), ivabradine (84.2 ± 8.4 bpm***/105.4 ± 14.6**), and O-3-FA (88.6 ± 7.9 bpm*/112.1/14.9*).
Conclusions: The HRV data of adolescents with dysautonomia after COVID-19 disease/vaccination are not significantly different from a historical control of adolescents with dysautonomia due to psychosomatic diseases prior to the pandemic. Low-dose propranolol > ivabradine > omega-3 fatty acids significantly decrease elevated heart rates in patients with IST and the heart rate increases in patients with POTS and may be beneficial in these children with dysautonomia.

Symptom patterns and life with post-acute COVID-19 in children aged 8-17: a mixed methods studyprotocol

Abstract:

Background: While there is a substantial body of knowledge about acute COVID-19, less is known about long-COVID, where symptoms continue beyond four weeks.

Aim: This study aims to describe longer-term effects of COVID-19 infection in children and young people (CYP) and identify their needs in relation to long-COVID.

Design & setting: This study comprises an observational prospective cohort study and a linked qualitative study, identifying participants aged 8-17 years in the West Midlands of England.

Method: CYP will be invited to complete online questionnaires to monitor incidences and symptoms of Covid-19 over a 12-month period. CYP who have experienced long-term effects of COVID will be invited to interview, and those currently experiencing symptoms will be asked to document their experiences in a diary. Professionals who work with CYP will be invited to explore the impact of long-COVID on the wider experiences of CYP, in a focus group. Descriptive statistics will be used to describe the incidence and rates of resolution of symptoms, and comparisons made between exposed and non-exposed groups. Logistic regression models will be used to estimate associations between candidate predictors and the development of long-COVID, and linear regression will be used to estimate associations between candidate predictors. Qualitative data will be analysed thematically using the constant comparison method.

Conclusion: This study will describe features and symptoms of long-COVID and explore the impact of long-COVID within the lives of CYP and their families, to provide better understanding of long-COVID and inform clinical practice.

Computable Clinical Phenotyping of Postacute Sequelae of COVID-19 in Pediatrics Using Real-World Data

INTRODUCTION:

Since the SARS-CoV-2 pandemic began in late 2019, over 13 million children in the United States have been infected with the virus [1]. Although many of these acute infections have not resulted in severe morbidity or mortality, a subset of children and adolescents have experienced recurrent or persistent symptoms beyond the typical recovery period [2]. The constellation of findings that occur postinfection is known as postacute sequelae of SARS-CoV-2 (PASC), or colloquially as “long-Covid.” The U.S. Centers for Disease Control and Prevention (CDC) defines PASC as a wide range of health problems that linger for more than 4 weeks following an acute COVID-19 infection [3]. Although this is an area of active research, relatively little is currently known about its clinical epidemiology in the pediatric population.

Considering the large number of children who have been affected by COVID-19, it is critical that we monitor the rates, trends, and outcomes of PASC in this population. An important first step toward these efforts is the development of a tool that can quickly and easily identify cases in large clinical populations. With the widespread adoption of electronic health records (EHR), it is now possible to develop computable phenotypes using data that are collected for clinical care, which can be used for population-level analysis to inform the public health response [4, 5]. In this report, we describe a novel phenotyping algorithm to define the burden, clinical spectrum, and outcomes of pediatric PASC using real-world data.

Pediatric Post-Acute Sequelae of SARS-CoV-2 infection

Abstract:

Aim: Youth who have not recovered from COVID-19 have been referred to as having Post-Acute Sequelae of SARS-CoV-2 Infection (PASC). The goal of this study was to better understand which symptoms persisted since onset of infection and how these symptoms compare to symptoms experienced by those with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS).

Method: A sample of 19 parents who had a child with PASC were recruited using social media to fill out a questionnaire detailing symptoms at two time points. The first time point included their child’s current symptoms and the second captured symptoms at initial infection. These participants were compared to a sample of 19 youth with ME/CFS.

Results: Findings indicated significant decreases among several immune, neuroendocrine, pain, post-exertional malaise (PEM), and COVID-19 Centers for Disease Control and Prevention (CDC) domain symptoms from time of acute infection to time of current reporting. Fatigue remained at a high level as did several symptoms within the sleep and PEM domains. Participants with ME/CFS had overall worse symptomatology when compared to participants with PASC, especially in the neurocognitive domain.

Conclusion: Most symptoms of those with PASC decline over time, but several remain at high levels, including fatigue. These findings are helpful in better understanding common symptom presentation profiles for youth with PASC and can be used to more adequately tailor diagnostic criteria and treatment strategies for youth.

Mid- and Long-Term Atrio-Ventricular Functional Changes in Children after Recovery from COVID-19

Abstract:

Background: Although most children may experience mild to moderate symptoms and do not require hospitalization, there are little data on cardiac involvement in COVID-19. However, cardiac involvement is accurately demonstrated in children with MISC. The objective of this study was to evaluate cardiac mechanics in previously healthy children who recovered from severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection in a long-term follow-up by means of two-dimensional speckle-tracking echocardiography (STE).
Methods: We analyzed a cohort of 157 paediatric patients, mean age 7.7 ± 4.5 years (age range 0.3–18 years), who had a laboratory-confirmed diagnosis of SARS-CoV-2 infection and were asymptomatic or mildly symptomatic for COVID-19. Patients underwent a standard transthoracic echocardiogram and STE at an average time of 148 ± 68 days after diagnosis and were divided in three follow-up groups (<180 days, 180–240 days, >240 days). Patients were compared with 107 (41 females—38%) age- and BSA-comparable healthy controls (CTRL).
Results: Left ventricular (LV) global longitudinal strain (post-COVID-19: −20.5 ± 2.9%; CTRL: −21.8 ± 1.7%; p < 0.001) was significantly reduced in cases compared with CTRLs. No significant differences were seen among the three follow-up groups (p = NS). Moreover, regional longitudinal strain was significantly reduced in LV apical-wall segments of children with disease onset during the second wave of the COVID-19 pandemic compared to the first wave (second wave: −20.2 ± 2.6%; first wave: −21.2 ± 3.4%; p = 0.048). Finally, peak left atrial systolic strain was within the normal range in the post-COVID-19 group with no significant differences compared to CTRLs.
Conclusions: Our study demonstrated for the first time the persistence of LV myocardial deformation abnormalities in previously healthy children with an asymptomatic or mildly symptomatic (WHO stages 0 or 1) COVID-19 course after an average follow-up of 148 ± 68 days. A more significant involvement was found in children affected during the second wave. These findings imply that subclinical LV dysfunction may also be a typical characteristic of COVID-19 infection in children and are concerning given the predictive value of LV longitudinal strain in the general population.

Feasibility Assessment of a School Nurse-Led Approach Using Chronic Absenteeism to Establish the School-Based Active Surveillance Process

Abstract:

This article shares what was learned from the feasibility assessment of a nurse-led school-based active surveillance (SBAS) pilot to track chronic absenteeism using myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) as an exemplar. This pilot encompassed a 3-year period with training and feedback from school nurses (SNs) on data collection and ME/CFS. SNs found that the SBAS process helped them effectively identifying undiagnosed conditions.

The assessment revealed the importance of focusing outreach efforts and establishing relationships with the school leadership in developing health policies and programs in the school setting. The pilot data were used to develop a manual to guide SNs for the SBAS process. This can be viewed as a model for SNs in establishing a surveillance to identify and track conditions like ME/CFS. With overlapping symptoms of Long COVID to ME/CFS, this assessment may provide insights for additional efforts to understand the impact of Long COVID on students’ education.

Clinical assessment of children with long COVID syndrome

Abstract:

Background: There is a need for further understanding pediatric long COVID syndrome (LCS) to be able to create specific case definitions and guidelines for providing good clinical care.

Methods: Medical records of all LCS patients who presented at our designated LC clinic were collected. We carried out descriptive analyses summarizing the history, clinical presentation, and findings of children, while doing a diagnosis of exclusion with multi-disciplinary medical examinations (physical, laboratory, and radiological examinations, specialist consultations, etc.) without a control group.

Results: Most children reported at least minor impairment to their quality of life, of which 17 (23%) had moderate or severe difficulties. Findings that could be directly connected to the linked complaint category were observed in an average of 18%, respiratory symptoms with objective alterations being the most frequent (37%). Despite our detecting mostly non-specific conditions, in a smaller number we identified well-described causes such as autoimmune thyroiditis (7%).

Conclusions: The majority of children stated an impairment in their quality of life, while symptom-related conditions were detected only in a minority. Controlled studies are needed to separate the effect of the pandemic era from the infection itself. Evidence-based pediatric guidelines could aid to rationalize the list of recommended examinations.

Impact: Long COVID syndrome is a complex entity with a great impact on children’s everyday lives. Still, there is no clear guidance for pediatric clinical management. Systematic, detailed studies with medical assessment findings could aid the process of creating evidence-based guidelines. We present validated systematic information collected during in-person medical assessments with detailed medical findings and quality of life changes. While making a diagnosis of exclusion, we could confirm symptom-related conditions only in a minority of children; however, the majority reported at least minor impairment to their quality of life.
