Long COVID in Children, Adults, and Vulnerable Populations: A Comprehensive Overview for an Integrated Approach. Diseases 2024; 12:95. [PMID: 38785750 PMCID: PMC11120262 DOI: 10.3390/diseases12050095] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2024] [Revised: 04/27/2024] [Accepted: 05/03/2024] [Indexed: 05/25/2024] Open
Abstract
Long COVID affects both children and adults, including subjects who experienced severe, mild, or even asymptomatic SARS-CoV-2 infection. We have provided a comprehensive overview of the incidence, clinical characteristics, risk factors, and outcomes of persistent COVID-19 symptoms in both children and adults, encompassing vulnerable populations, such as pregnant women and oncological patients. Our objective is to emphasize the critical significance of adopting an integrated approach for the early detection and appropriate management of long COVID. The incidence and severity of long COVID symptoms can have a significant impact on the quality of life of patients and the course of disease in the case of pre-existing pathologies. Particularly, in fragile and vulnerable patients, the presence of PASC is related to significantly worse survival, independent from pre-existing vulnerabilities and treatment. It is important try to achieve an early recognition and management. Various mechanisms are implicated, resulting in a wide range of clinical presentations. Understanding the specific mechanisms and risk factors involved in long COVID is crucial for tailoring effective interventions and support strategies. Management approaches involve comprehensive biopsychosocial assessments and treatment of symptoms and comorbidities, such as autonomic dysfunction, as well as multidisciplinary rehabilitation. The overall course of long COVID is one of gradual improvement, with recovery observed in the majority, though not all, of patients. As the research on long-COVID continues to evolve, ongoing studies are likely to shed more light on the intricate relationship between chronic diseases, such as oncological status, cardiovascular diseases, psychiatric disorders, and the persistent effects of SARS-CoV-2 infection. This information could guide healthcare providers, researchers, and policymakers in developing targeted interventions.

[Formula: see text] Cognitive disengagement syndrome in pediatric patients with long COVID: associations with mood, anxiety, and functional impairment. Child Neuropsychol 2024; 30:652-672. [PMID: 37667487 DOI: 10.1080/09297049.2023.2252967] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2023] [Accepted: 08/17/2023] [Indexed: 09/06/2023]
Abstract
Children with long COVID often report symptoms that overlap with cognitive disengagement syndrome (CDS, previously sluggish cognitive tempo (SCT)), a set of behaviors distinct from attention-deficit/hyperactivity disorder (ADHD) including excessive daydreaming, mental fogginess, and slowed behavior and thinking. Those with long COVID also frequently report low mood and anxiety, which are linked to CDS. The relationships between cognitive difficulties, mood, and functional impairment have yet to be explored in pediatric long COVID. Specifically, it is unclear how much cognitive difficulties (CDS, inattention) contribute to functional impairment, when accounting for mood/anxiety symptoms in this population. Retrospective parent-reported data was collected from 34 patients with long COVID (22 females, Mage = 14.06 years, SD = 2.85, range 7-19) referred for neuropsychological consultation through a multidisciplinary Post-COVID-19 clinic. Compared to community and clinically referred samples, on average, long COVID patients showed elevated CDS symptoms, including Sluggish/sleepy (e.g., fatigue) and Low Initiation subscales (e.g., difficulty performing goal directed behaviors). Low Initiation, mood, anxiety, and inattention were associated with functional impairment. In multiple hierarchical regression models, after controlling for mood and anxiety, Low Initiation and inattention were no longer predictive of functional impairment. Instead, anxiety remained the sole predictor of functional impairment. Our results demonstrate that children with long COVID have high levels of CDS symptoms. The association between cognitive difficulties and functional impairment dissipated with the inclusion of mood and anxiety, suggesting behavioral health interventions targeting anxiety may help improve daily functioning and quality of life in pediatric long COVID patients.

Cardiopulmonary function in paediatric post-COVID-19: a controlled clinical trial. Eur J Pediatr 2024; 183:1645-1655. [PMID: 38193996 PMCID: PMC11001705 DOI: 10.1007/s00431-024-05421-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/24/2023] [Revised: 12/26/2023] [Accepted: 01/02/2024] [Indexed: 01/10/2024]
Abstract
Recently, the importance of post-COVID-19 in children has been recognized in surveys and retrospective chart analysis. However, objective data in the form of cardiopulmonary exercise test as performed in adults suffering from this condition are still lacking. This study aimed to investigate the cardiopulmonary effects of post-COVID-19 on children and adolescents. In this cross-sectional study (the FASCINATE study), children fulfilling the criteria of post-COVID-19 and an age- and sex-matched control group underwent cardiopulmonary exercise testing on a treadmill and completed a questionnaire with regard to physical activity before, during and after the infection with SARS-CoV-2. We were able to recruit 20 children suffering from post-COVID-19 (mean age 12.8 ± 2.4 years, 60% females) and 28 control children (mean age 11.7 ± 3.5 years, 50% females). All participants completed a maximal treadmill test with a significantly lowerV ˙ O 2 peak in the post-COVID-19 group (37.4 ± 8.8 ml/kg/min vs. 43.0 ± 6.7 ml/kg/min. p = 0.019). This significance did not persist when comparing the achieved percentage of predictedV ˙ O 2 peak . There were no significant differences for oxygen pulse, heart rate, minute ventilation or breathing frequency. Conclusion: This is the first study to investigate post-COVID-19 in children using the cardiopulmonary exercise test. Although there was a significantly reducedV ˙ O 2 peak in the post-COVID-19 group, this was not true for the percent of predicted values. No pathological findings with respect to cardiac or pulmonary functions could be discerned. Deconditioning was the most plausible cause for the experienced symptoms. Trial registration: clinicaltrials.gov, NCT054445531, Low-field Magnetic Resonance Imaging in Pediatric Post Covid-19-Full Text View-ClinicalTrials.gov. What is Known: • The persistence of symptoms after an infection with SARS-CoV 2, so-called post-COVID-19 exists also in children. • So far little research has been conducted to analyze this entity in the pediatric population. What is New: • This is the first study proving a significantly lower cardiopulmonary function in pediatric patients suffering from post-COVID-19 symptoms. • The cardiac and pulmonary function appear similar between children suffering from post-COVID-19 and those who don't, but the peripheral muscles seem affected.

The knowns and unknowns of long COVID-19: from mechanisms to therapeutical approaches. Front Immunol 2024; 15:1344086. [PMID: 38500880 PMCID: PMC10944866 DOI: 10.3389/fimmu.2024.1344086] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2023] [Accepted: 02/14/2024] [Indexed: 03/20/2024] Open
Abstract
The coronavirus disease 2019 (COVID-19) pandemic caused by SARS-CoV-2 has been defined as the greatest global health and socioeconomic crisis of modern times. While most people recover after being infected with the virus, a significant proportion of them continue to experience health issues weeks, months and even years after acute infection with SARS-CoV-2. This persistence of clinical symptoms in infected individuals for at least three months after the onset of the disease or the emergence of new symptoms lasting more than two months, without any other explanation and alternative diagnosis have been named long COVID, long-haul COVID, post-COVID-19 conditions, chronic COVID, or post-acute sequelae of SARS-CoV-2 (PASC). Long COVID has been characterized as a constellation of symptoms and disorders that vary widely in their manifestations. Further, the mechanisms underlying long COVID are not fully understood, which hamper efficient treatment options. This review describes predictors and the most common symptoms related to long COVID's effects on the central and peripheral nervous system and other organs and tissues. Furthermore, the transcriptional markers, molecular signaling pathways and risk factors for long COVID, such as sex, age, pre-existing condition, hospitalization during acute phase of COVID-19, vaccination, and lifestyle are presented. Finally, recommendations for patient rehabilitation and disease management, as well as alternative therapeutical approaches to long COVID sequelae are discussed. Understanding the complexity of this disease, its symptoms across multiple organ systems and overlapping pathologies and its possible mechanisms are paramount in developing diagnostic tools and treatments.

Abstract
BACKGROUND Although the long-term consequences of the Coronavirus Disease-2019 (COVID-19) pandemic are yet to be fully comprehended, a syndrome symptomatically akin to the COVID-19 disease has been defined, for children and adolescents, in February 2023 by the World Health Organization (WHO) as 'post COVID-19 condition' (PCC). Potential consequences of COVID-19 that affect developmental milestones in children and adolescents should be comprehended in their magnitude and duration. The aim is to investigate the most common symptoms and predictors or risk factors for pediatric PCC. METHODS In this umbrella review, the population of interest was defined as children and adolescents from 0 to 19 years old presenting PCC symptoms as defined by the WHO in the International Classification of Diseases. The intervention considered was general follow-up activity to monitor the patients' recovery status. No comparator was chosen, and the outcomes were symptoms of PCC and predictors or risk factors of developing PCC. Methodological quality, risk of bias and the level of overlap between studies were assessed. A random-effects meta-analytic synthesis of respective estimates with inverse variance study weighting was carried out, for the primary studies included by the reviews retrieved, regarding predictors or risk factors reported. RESULTS We identified six eligible systematic reviews, five with meta-analyses, from three databases. The most common symptoms reported were fatigue and respiratory difficulties; female sex and older age were the most reported factors associated with the development of pediatric PCC. CONCLUSIONS A deeper understanding of pediatric PCC requires well-designed and clearly defined prospective studies, symptom differentiation, and adequate follow-up.

[PMID: 38281902 DOI: 10.1016/j.vaccine.2024.01.055] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2023] [Revised: 10/03/2023] [Accepted: 01/18/2024] [Indexed: 01/30/2024]
Abstract
PURPOSE SARS-CoV-2 vaccine safety is of major interest worldwide, and transparent information about potential side effects is essential to decrease vaccine hesitancy. The aim of this study was to assess SARS-CoV-2 BNT162b2 vaccine short-term side effects among children aged 5-11 years. METHODS An observational, cross sectional study of vaccine side-effects using electronic surveys sent to parents one week post administration of BNT162b2 vaccine to their child in a large health maintenance organization in Israel. RESULTS First dose and second dose surveys were filled for 5,842 and 6,126 children, respectively, with a response rate of 32.1% and 24.8%. Local side effects were reported by 68.7% and 69.1% of the first and second survey respondents, and general side effects were reported by 20.8% and 34.5% of them. The symptoms most frequently reported were fatigue, headache and myalgia. Duration of symptoms lasted three days or less among 86.5% and 81.5% of first and second dose survey respondents. Most respondents (92%) reported that their child did not need any medical consultation following vaccination. CONCLUSIONS We found further support for the BNT162b2 SARS-CoV-2 vaccine short- term safety among children aged 5-11 years. With ongoing pandemic and future booster COVID-19 vaccines, these findings can encourage vaccine confidence for parents and providers.

Potential Predictors of Long COVID in Italian Children: A Cross-Sectional Survey. CHILDREN (BASEL, SWITZERLAND) 2024; 11:221. [PMID: 38397333 PMCID: PMC10887525 DOI: 10.3390/children11020221] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/06/2023] [Revised: 02/01/2024] [Accepted: 02/05/2024] [Indexed: 02/25/2024]
Abstract
BACKGROUND Identifying predictive factors of long COVID syndrome (LCS) is essential to preventing and managing this condition. We investigated the prevalence, symptoms, and risk factors of LCS in a cohort of Italian children and adolescents. METHODS We carried out a cross-sectional survey on demographic characteristics and clinical data related to COVID-19 phase and LCS in a cohort of children and adolescents, sending a questionnaire by using the PEDIATOTEM platform. RESULTS The prevalence of LCS was 25% (99/396). The most frequent symptoms of LCS included nasal congestion, diarrhea, headache, and fatigue. We found no association between demographic data (gender, age, and ethnicity) and LCS. Additionally, we showed that patients with concurrent allergic rhinitis, atopic dermatitis, respiratory disease, gastrointestinal disease, and rheumatologic disease had a higher risk of LCS than patients without those comorbidities. Patients experiencing fatigue, muscle, and abdominal pain in COVID-19 showed a higher risk of LCS than patients complaining of other symptoms. We found no association between vaccination and LCS. CONCLUSIONS Specific comorbidities or symptoms during acute illness were identified as being risk factors for LCS. Understanding which are the risk factors for LCS could yield a clearer picture of its pathogenesis.

Subjective Smell Disturbances in Children with Sars-Cov-2 or Other Viral Infections do not Correspond with Olfactory Test Results. KLINISCHE PADIATRIE 2024; 236:129-138. [PMID: 38262421 DOI: 10.1055/a-2208-6245] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 01/25/2024]
Abstract
BACKGROUND Olfactory dysfunction associated with SARS-CoV-2 infection in children has not been verified by a validated olfactory test. We aimed to determine whether these complaints are objectifiable (test-based hyposmia), how often they occur during acute SARS-CoV-2 infection compared to other upper respiratory tract infections (URTI), as well as in children recovered from COVID-19 compared to children with long COVID. METHODS Olfactory testing (U-sniff test; hyposmia<8 points) and survey-based symptom assessments were performed in 434 children (5-17 years; 04/2021-06/2022). 186 symptom-free children served as controls. Of the children with symptoms of acute respiratory tract infection, SARS-CoV-2 PCR test results were positive in 45 and negative in 107 children (URTI group). Additionally, 96 children were recruited at least 4 weeks (17.6±15.2 weeks) after COVID-19, of whom 66 had recovered and 30 had developed long COVID. RESULTS Compared to controls (2.7%), hyposmia frequency was increased in all other groups (11-17%, p<0.05), but no between-group differences were observed. Only 3/41 children with hyposmia reported complaints, whereas 13/16 children with complaints were normosmic, with the largest proportion being in the long-COVID group (23%, p<0.05). CONCLUSION Questionnaires are unsuitable for assessing hyposmia frequency in children. Olfactory complaints and hyposmia are not specific for SARS-CoV-2 infection. The number of complaints in the long-COVID group could result from aversive olfactory perception, which is undetectable with the U-sniff test.

International Care programs for Pediatric Post-COVID Condition (Long COVID) and the way forward. Pediatr Res 2024:10.1038/s41390-023-03015-0. [PMID: 38287106 DOI: 10.1038/s41390-023-03015-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/09/2023] [Revised: 11/16/2023] [Accepted: 12/15/2023] [Indexed: 01/31/2024]
Abstract
BACKGROUND Pediatric Post-COVID-Condition (PPCC) clinics treat children despite limited scientific substantiation. By exploring real-life management of children diagnosed with PPCC, the International Post-COVID-Condition in Children Collaboration (IP4C) aimed to provide guidance for future PPCC care. METHODS We performed a cross-sectional international, multicenter study on used PPCC definitions; the organization of PPCC care programs and patients characteristics. We compared aggregated data from PPCC cohorts and identified priorities to improve PPCC care. RESULTS Ten PPCC care programs and six COVID-19 follow-up research cohorts participated. Aggregated data from 584 PPCC patients was analyzed. The most common symptoms included fatigue (71%), headache (55%), concentration difficulties (53%), and brain fog (48%). Severe limitations in daily life were reported in 31% of patients. Most PPCC care programs organized in-person visits with multidisciplinary teams. Diagnostic testing for respiratory and cardiac morbidity was most frequently performed and seldom abnormal. Treatment was often limited to physical therapy and psychological support. CONCLUSIONS We found substantial heterogeneity in both the diagnostics and management of PPCC, possibly explained by scarce scientific evidence and lack of standardized care. We present a list of components which future guidelines should address, and outline priorities concerning PPCC care pathways, research and international collaboration. IMPACT Pediatric Post-COVID Condition (PPCC) Care programs have been initiated in many countries. Children with PPCC in different countries are affected by similar symptoms, limiting many to participate in daily life. There is substantial heterogeneity in diagnostic testing. Access to specific diagnostic tests is required to identify some long-term COVID-19 sequelae. Treatments provided were limited to physical therapy and psychological support. This study emphasizes the need for evidence-based diagnostics and treatment of PPCC. The International Post-COVID Collaboration for Children (IP4C) provides guidance for guideline development and introduces a framework of priorities for PPCC care and research, to improve PPCC outcomes.

Abstract
OBJECTIVE This study aimed to determine psychosocial differences between children with Long-COVID Syndrome (LCS) and two control groups (i.e., children who did not have COVID-19 and children who had previously had COVID-19 but did not develop LCS) from a bio-psycho-social and psychosomatic perspective. To classify children in these three groups, we examined the percentage of children meeting criteria for LCS, the type, frequency, perceived severity of symptoms, and their prevalence compared with children who never had SARS-CoV-2 infection. METHODS Data were collected from 198 Italian mothers of children aged 4 to 13 years using a cross-sectional web-based case-control survey. Of these, 105 were mothers of children who had contracted SARS-CoV-2 and 94 were mothers of children who had previously had COVID-19. Information was collected on the type and frequency of symptoms commonly referred to as "Long-COVID symptoms" and psychosocial dimensions (i.e., maternal and child health anxiety, COVID-19 anxiety, adjustment, and child deprivation). Descriptive analyses, chi-square tests, Student's T-Test, and analyses of variance were performed. RESULTS 29 children (15% of the total sample) developed LCS, mostly in the neurological/neuropsychiatric domain (59%), and of mild intensity. Regarding psychosocial and psychological dimensions, maternal health anxiety, child deprivation, and fear of SARS-CoV-2 infection differed between groups, with the first two dimensions higher in children with LCS than in controls and the latter lower in children with LCS than in controls. CONCLUSION This study sheds light on the need of integrating a psychosocial approach into the medical care of children with LCS and their caregivers.

Clinical and healthcare utilization outcomes during the 6 months following COVID infection in children. Pediatr Res 2024; 95:342-349. [PMID: 37587368 DOI: 10.1038/s41390-023-02762-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/28/2022] [Revised: 05/30/2023] [Accepted: 07/16/2023] [Indexed: 08/18/2023]
Abstract
BACKGROUND We aimed to identify the impact of COVID infection in children in the US prior to vaccine availability on clinical and healthcare utilization outcomes within 6 months of infection. METHODS Using claims data from a large national insurer, we identified 223,842 children with a COVID diagnosis in May 2020-March 2021 and matched them to 223,842 children with a COVID test and no diagnosis. We compared the two cohorts' outcomes during the 6 months after infection/test. RESULTS Uncommon acute adverse events occurring in <0.5% of cases, including MIS-C (relative risk (RR) = 45.2), myocarditis (RR = 10.3), acute heart failure (RR = 2.14), sepsis (RR = 2.02), and viral pneumonia (RR = 2.43) were more frequent in the COVID cohort (all p < 0.001). Development of arrhythmias (RR = 1.24, p < 0.001) and atherosclerotic cardiovascular disease (RR = 1.41, p = 0.007) were more common in the COVID group, while behavioral health disorders were less common (RR = 0.94, p < 0.001). Lab testing and imaging were slightly higher in the COVID group (RR ranging 1.05-1.11 depending on the service and timeframe), though medical costs did not increase. CONCLUSION Severe disease and diagnoses of new conditions are rare in children following COVID infection. We observed an increase in cardiac complications, though they may not last long term. IMPACT Few studies have analyzed the association between COVID infection and medium-term outcomes in children. Our study of >447,000 geographically and socioeconomically diverse children in the US found that uncommon acute adverse events, including myocarditis, MIS-C, and acute heart failure, were more frequent in children with COVID than matched controls, and development of arrhythmias and cardiovascular disease were 1.2 and 1.4 times more common, respectively. Six-month healthcare utilization was similar between cohorts. We provide data on the risks of COVID in children, particularly with respect to cardiac complications, that decision makers may find useful when weighing the benefits and harms of preventive measures.

Abstract
Coronavirus disease 2019 (COVID-19) has caused tremendous morbidity and mortality worldwide. The large number of post-COVID survivors has drawn attention to the management of post-COVID condition, known as long COVID. This review examines current knowledge of long COVID, regarding its epidemiology, mechanism, and clinical presentations in both adults and children. We also review the rehabilitation principles, modules, and effects, and share Taiwan's efforts to provide a top-down, nationwide care framework for long COVID patients. Dyspnea, chronic cough, and fatigue are the most commonly reported symptoms in the first 6 months after infection, but cognitive impairment and psychological symptoms may persist beyond this time. Several possible mechanisms behind these symptoms were proposed, but remained unconfirmed. These symptoms negatively impact individuals' function, activities, participation and quality of life. Rehabilitation is a key element of management to achieve functional improvement. Early management should start with comprehensive evaluation and identification of red flags. Exercise-based therapy, an essential part of management of long COVID, can be conducted with different modules, including telerehabilitation. Post-exertional symptom exacerbation and orthostatic hypotension should be carefully monitored during exercise. Randomized control trials with a large sample size are needed to determine the optimal timing, dosage, and modules.

Abstract
BACKGROUND Patient-level data on the clinical features and outcomes of children and young people referred for possible long coronavirus disease (COVID) can guide clinicians on what to expect in managing patients and advising families. METHODS A Post-Acute COVID Clinic for persons <21 years of age was established in October 2020. Intake was standardized and management was tailored to presenting symptoms. Data were abstracted from the charts of all patients evaluated through December 2021, and the study cohort consisted of patients who had a history of confirmed severe acute respiratory syndrome coronavirus 2 infection, had ≥1 symptom persisting for ≥12 weeks and had no pre-existing diagnosis that explained the symptoms. A structured follow-up interview was conducted in early 2022. RESULTS A total of 104 patients were referred, 81 of whom met inclusion criteria. The median age was 14 years (interquartile range, 13-16), and most were female, White/Caucasian and had commercial health insurance. Patients reported previously good health but over half reported moderate-to-severe disability at their first visit. Two clusters of presenting symptoms-fatigue with multiple symptoms, and fatigue and headache with cardiopulmonary symptoms-were identified. Extensive routine testing did not affirm alternative diagnoses. Incident conditions-most commonly anxiety, depression and/or panic disorder; migraines; and autonomic dysfunction-were diagnosed on clinical grounds. Telephone interviews (N = 55) revealed that 78% of patients were improved by about 6 months. CONCLUSIONS Within the limits of a single-center, referral-based, observational cohort, this study provides reassurance to patients and parents in that most cases of long COVID were self-limited. Extensive evaluations may be more useful in ruling out alternative diagnoses than in affirming specific physiologic disturbances.

Abstract
AIM Children have largely been unaffected by severe COVID-19 compared to adults, but data suggest that they may have experienced new conditions after developing the disease. We compared outcomes in children who had experienced COVID-19 and healthy controls. METHODS A retrospective nested cohort study assessed the incidence rate of new-onset conditions after COVID-19 in children aged 0-14 years. Data were retrieved from an Italian paediatric primary care database linked to Veneto Region registries. Exposed children with a positive nasopharyngeal swab were matched 1:1 with unexposed children who had tested negative. Conditional Cox regression was fitted to estimate the adjusted hazard ratios (aHR) and 95% confidence intervals (CI) for the exposure and outcome associations after adjusting for covariates. RESULTS We compared 1656 exposed and 1656 unexposed children from 1 February 2020 to 30 November 2021. The overall excess risk for new-onset conditions after COVID-19 was 78% higher in the exposed than unexposed children. We found significantly higher risks for some new conditions in exposed children, including mental health issues (aHR 1.8, 95% CI 1.1-3.0) and neurological problems (aHR 2.4, 95% CI 1.4-4.1). CONCLUSION Exposed children had a 78% higher risk of developing new conditions of interest after COVID-19 than unexposed children.

[PMID: 37959356 PMCID: PMC10648595 DOI: 10.3390/jcm12216891] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2023] [Revised: 10/22/2023] [Accepted: 10/29/2023] [Indexed: 11/15/2023] Open
Abstract
Background: Studies on post-COVID-19 condition (PCC) in adults have shown deterioration in pulmonary function tests (PFTs), mainly a diffusion limitation. Among the pediatric population, data are scarce. Aim: To characterize PFTs in children with PCC, including changes over time. Methods: A prospective longitudinal study of children with defined PCC and respiratory complaints who were referred to a designated multidisciplinary clinic from 11/2020 to 12/2022. Results: Altogether, 184 children with a mean age of 12.4 years (SD 4.06) were included. A mild obstructive pattern was demonstrated in 19/170 (11%) at presentation, as indicated by spirometry and/or positive exercise challenge test and/or reversibility post bronchodilators, only three had a previous diagnosis of asthma. Lung volumes and diffusion were normal in all but one patient (1/134, 0.7%). Exhaled nitric oxide levels were elevated in 32/144 (22%). A total of 33 children who had repeated PFTs had normal or near-normal PFTs on follow-up testing, including seven (21.2%) who had mild obstructive PFTs at presentation. Multivariate analysis identified older age [OR 1.36 (95% CI:1.07-1.75)], specific imaging findings (prominent bronchovascular markings (OR 43.28 (95% CI: 4.50-416.49)), and hyperinflation (OR 28.42, 95% CI: 2.18-370.84)] as significant predictors of an obstructive pattern on PFTs. Conclusions: In children with PCC and respiratory symptoms, the most common impairment was a mild obstructive pattern; most were without a history of asthma. Improvement was witnessed in long-term follow-up. In contrast to the adult population, no diffusion limitation was found. Empirical periodic inhaler therapy may be considered in children with factors associated with PFT abnormalities.

Evaluation of post-COVID symptoms of the SARS-CoV-2 Delta and Omicron variants in children: a prospective study. Eur J Pediatr 2023; 182:4565-4571. [PMID: 37526704 DOI: 10.1007/s00431-023-05134-6] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/06/2023] [Revised: 07/20/2023] [Accepted: 07/23/2023] [Indexed: 08/02/2023]
Abstract
The post-COVID-19 syndrome is a new syndrome defined in patients with a history of probable or confirmed SARS-CoV-2 infection, usually within three months of the onset of COVID-19, with symptoms and effects lasting at least 2 months. This study is aimed at comprehensively comparing symptoms of the post-COVID-19 syndrome in children with Delta and Omicron variants. This prospective study included children with COVID-19 followed in hospitalized or outpatient clinics in a tertiary hospital. We used a special questionnaire to ask about the presence of persistent symptoms more than 12 weeks after the initial diagnosis. Patients with positive SARS-CoV-2 PCR were selected randomly and grouped according to the dominant variants in our country at that time as follows: Omicron group (after December 16, 2021); Delta (B.1.617.2) group (August 15, 2021, and December 15, 2021). This study included 200 children, 71 of whom were in the Delta group and 129 of whom were in the Omicron group. Weakness (8.5% vs. 1.6%; p = 0.017), the impact of physical efforts (5.6% vs. 3.9%; p = 0.020), fatigue (22.5% vs. 8.5%; p = 0.009), anxiety disorder (12.7% vs. 0.8%; p = 0.001), and gastrointestinal changes (12.7% vs. 4.7%, p = 0.050) were statistically significantly higher in patients with the Delta variant compared to patients with the Omicron variant. There were no differences between the groups regarding anorexia, anosmia/ageusia, arthralgia, influenza-like symptoms, sleeping disorders, decreased physical activity daily, headache, need for analgesia, concentration and memory disorder, and weight loss (p > 0.05). Conclusion: This study showed that weakness, the impact of physical efforts, fatigue, anxiety disorder, and gastrointestinal changes were more frequent in the Delta group compared to the Omicron group. The incidence of post-COVID-19 syndrome is high in children as well as adults and affects several systems; therefore, it should be kept in mind that children should be followed for post-COVID-19 syndrome. What is Known: • Despite the milder severity of acute COVID-19 in children, post-COVID-19 symptoms may occur. The post-COVID-19 condition is complex and novel, especially in the pediatric population. What is New: • Post-COVID-19 symptoms in children differ depending on the viral variant. Post-COVID-19 syndrome has a great impact on the social life of children which may have serious and long-term effects.

Long-term humoral signatures following acute pediatric COVID-19 and Multisystem Inflammatory Syndrome in Children. Pediatr Res 2023; 94:1327-1334. [PMID: 37173406 PMCID: PMC10176275 DOI: 10.1038/s41390-023-02627-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/11/2022] [Revised: 03/21/2023] [Accepted: 03/30/2023] [Indexed: 05/15/2023]
Abstract
BACKGROUND Although most children experience mild symptoms during acute SARS-CoV-2 infection, some develop the severe post-COVID-19 complication, Multisystem Inflammatory Syndrome in Children (MIS-C). While acute presentations of COVID-19 and MIS-C have been well immunophenotyped, little is known about the lasting immune profile in children after acute illness. METHODS Children 2 months-20 years of age presenting with either acute COVID-19 (n = 9) or MIS-C (n = 12) were enrolled in a Pediatric COVID-19 Biorepository at a single medical center. We deeply profiled humoral immune responses and circulating cytokines following pediatric COVID-19 and MIS-C. RESULTS Twenty-one children and young adults provided blood samples at both acute presentation and 6-month follow-up (mean: 6.5 months; standard deviation: 1.77 months). Pro-inflammatory cytokine elevations resolved after both acute COVID-19 and MIS-C. Humoral profiles continue to mature after acute COVID-19, displaying decreasing IgM and increasing IgG over time, as well as stronger effector functions, including antibody-dependent monocyte activation. In contrast, MIS-C immune signatures, especially anti-Spike IgG1, diminished over time. CONCLUSIONS Here, we show the mature immune signature after pediatric COVID-19 and MIS-C, displaying resolving inflammation with recalibration of the humoral responses. These humoral profiles highlight immune activation and vulnerabilities over time in these pediatric post-infectious cohorts. IMPACT The pediatric immune profile matures after both COVID-19 and MIS-C, suggesting a diversified anti-SARS-CoV-2 antibody response after resolution of acute illness. While pro-inflammatory cytokine responses resolve in the months following acute infection in both conditions, antibody-activated responses remain relatively heightened in convalescent COVID-19. These data may inform long-term immunoprotection from reinfection in children with past SARS-CoV-2 infections or MIS-C.

True prevalence of long COVID in children: a narrative review. Front Microbiol 2023; 14:1225952. [PMID: 37789860 PMCID: PMC10543413 DOI: 10.3389/fmicb.2023.1225952] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2023] [Accepted: 08/23/2023] [Indexed: 10/05/2023] Open
Abstract
Contrary to what is true for adults, little is known about pediatric long COVID (LC). Studies enrolling children are relatively few and extremely heterogeneous. This does not allow to draw definitive conclusions on the frequency and pathogenesis of pediatric LC and limits the development of appropriate and effective measures to contain the clinical, social and economic impact of this condition on the pediatric population. Depending on the methods used to collect and analyze data, studies have found that the incidence rate of pediatric LC may vary from about 25% to less than 5%. However, despite true prevalence of pediatric LC cannot be exactly defined, studies comparing children with previous COVID-19 and uninfected controls have shown that most of the clinical manifestations detected in infected children, mainly mood symptoms, mental health disorders and heart abnormalities could be diagnosed with similar frequency and severity in uninfected subjects also. This seems to indicate that SARS-CoV-2 is the cause of pediatric LC only in a part of children and other factors play a relevant role in this regard. Pandemic itself with the persistent disruption of child lives may have caused persistent stress in all the pediatric population causing mood symptoms, mental health disorders or several organ and body system functional alterations, regardless SARS-CoV-2 infection. These suppositions suggest the need for long-term physical control of all the children after COVID-19 especially when they were already suffering from an underlying disease or have had a severe disease. Moreover, attention should be paid to the assessment of change in children's emotional and behavioral functioning in order to assure adequate interventions for the best emotional and behavioral well being. However, whatever its origin, it seems highly likely that the prevalence of the pediatric LC is set to decline in the future. Preliminary observations seem to suggest that recently developed SARS-CoV-2 variants are associated with less severe COVID-19. This suggests that, as already seen in adults, a lower number of pediatric virus-associated LC cases should occur. Furthermore, the use of COVID-19 vaccines, reducing incidence and severity of SARS-CoV-2 infection, may reduce risk of LC development. Finally, elimination of restrictive measures should significantly reduce mood symptoms and mental health disorders.

Risk of post-acute sequelae of SARS-CoV-2 infection associated with pre-coronavirus disease obstructive sleep apnea diagnoses: an electronic health record-based analysis from the RECOVER initiative. Sleep 2023; 46:zsad126. [PMID: 37166330 PMCID: PMC10485569 DOI: 10.1093/sleep/zsad126] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2022] [Revised: 03/20/2023] [Indexed: 05/12/2023] Open
Abstract
STUDY OBJECTIVES Obstructive sleep apnea (OSA) has been associated with more severe acute coronavirus disease-2019 (COVID-19) outcomes. We assessed OSA as a potential risk factor for Post-Acute Sequelae of SARS-CoV-2 (PASC). METHODS We assessed the impact of preexisting OSA on the risk for probable PASC in adults and children using electronic health record data from multiple research networks. Three research networks within the REsearching COVID to Enhance Recovery initiative (PCORnet Adult, PCORnet Pediatric, and the National COVID Cohort Collaborative [N3C]) employed a harmonized analytic approach to examine the risk of probable PASC in COVID-19-positive patients with and without a diagnosis of OSA prior to pandemic onset. Unadjusted odds ratios (ORs) were calculated as well as ORs adjusted for age group, sex, race/ethnicity, hospitalization status, obesity, and preexisting comorbidities. RESULTS Across networks, the unadjusted OR for probable PASC associated with a preexisting OSA diagnosis in adults and children ranged from 1.41 to 3.93. Adjusted analyses found an attenuated association that remained significant among adults only. Multiple sensitivity analyses with expanded inclusion criteria and covariates yielded results consistent with the primary analysis. CONCLUSIONS Adults with preexisting OSA were found to have significantly elevated odds of probable PASC. This finding was consistent across data sources, approaches for identifying COVID-19-positive patients, and definitions of PASC. Patients with OSA may be at elevated risk for PASC after SARS-CoV-2 infection and should be monitored for post-acute sequelae.

Abstract
Pediatric post-acute sequelae of SARS-CoV-2 (PASC) or "long COVID" are a complex multisystemic disease that affects children's physical, social, and mental health. PASC has a variable presentation, time course, and severity and can affect children even with mild or asymptomatic acute COVID-19 symptoms. Screening for PASC in children with a history of SARS-CoV-2 infection is important for early detection and intervention. A multifaceted treatment approach and utilization of multidisciplinary care, if available, are beneficial in managing the complexities of PASC. Lifestyle interventions, physical rehabilitation, and mental health management are important treatment approaches to improve pediatric PASC patients' quality of life.

Features of Myocarditis: Morphological Differential Diagnosis in Post-COVID-19 Children. Diagnostics (Basel) 2023; 13:2499. [PMID: 37568863 PMCID: PMC10417761 DOI: 10.3390/diagnostics13152499] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2023] [Revised: 07/17/2023] [Accepted: 07/24/2023] [Indexed: 08/13/2023] Open
Abstract
Myocarditis is characterized by dysfunction and destruction of cardiomyocytes, infiltrative inflammation, and development of fibrosis. Late diagnosis of myocarditis has been a serious global health problem, especially due to the spread of a new coronavirus infection. The aim of this review is to identify differences between myocarditis of viral etiology, including SARS-CoV-2 lesions, based on instrumental and pathomorphological findings. MATERIAL AND METHODS We analyzed publications covering the period from December 2019 to May 2023, published in publicly accessible international databases ("Medline", "PubMed", "Scopus"), with queries for the keywords "myocarditis", "children", "cardiovascular inflammation", "COVID-19", "SARS-CoV-2", "severe acute respiratory syndrome coronavirus 2", "differential diagnosis". RESULTS It was found that no unambiguous morphological criteria for the diagnosis of myocarditis coupled to SARS-CoV-2 lesions were identified. However, the detected histopathological changes such as virus-associated degeneration, apoptosis, cardiomyocyte necrosis, moderate interstitial hyperemia, myocardial tissue oedema, and capillary endothelial cell dysfunction were the major markers of SARS-CoV-2 infection. CONCLUSION It is necessary further reconsider morphological criteria to diagnose SARS-CoV-2-caused myocarditis, rather than solely relying on detecting viral RNA by PCR as the sole evidence-based criterion. Similar issues accompany diagnostics of myocardial lesions associated with other viral infections. Evidence for an etiological diagnosis of myocarditis can be provided by a comprehensive analysis of the diagnostic criteria obtained, confirming virus exposure, followed by development of distinct clinical symptoms, MRI and CT changes, and morphological criteria.

Abstract
INTRODUCTION Neurological/neuropsychiatric symptoms are commonly reported by children/young people with long COVID, especially headache, fatigue, cognitive deficits, anosmia and ageusia, dizziness, mood symptoms, and sleep problems. However, reported prevalence estimates are highly variable due to study heterogeneity and often small sample size; most studies only considered short-term follow-ups; and, apart from mood and sleep problems, neuropsychiatric conditions have received less attention. Considering the potential debilitating effects of neurological/neuropsychiatric conditions, a comprehensive review of the topic is timely, and needed to support clinical recognition as well as to set the direction for future research. AREAS COVERED The authors discuss neurological/neuropsychiatric manifestations of long COVID in pediatric populations, with a focus on prevalence, associated demographic characteristics, and potential pathogenetic mechanisms. EXPERT OPINION Children/young people may develop persistent neurological/neuropsychiatric symptoms following acute SARS-CoV-2 infection, which may affect daily functioning and well-being. Studies in larger samples with longer follow-ups are needed to clarify prevalence and symptom duration; as well as less investigated risk factors, including genetic predisposition, ethnicity, and comorbidities. Controlled studies may help separate infection-related direct effects from pandemic-related psychosocial stressors. Clarifying pathogenetic mechanisms is paramount to develop more targeted and effective treatments; whilst screening programs and psychoeducation may enhance early recognition.

Abstract
INTRODUCTION There is increasing evidence that also children can develop Long Covid. However, there are no specific reviews providing a clear description of reported respiratory symptoms and potential diagnostics. AREAS COVERED We performed on PubMed a systematic search of studies conducted on children aged less than 18 years with previous SARS-CoV-2 infection complaining about persistent respiratory symptoms; the aim of our review is to characterize the incidence, pattern and duration of respiratory symptoms after the acute infection in pediatric population. EXPERT OPINION Children can develop persisting respiratory symptoms, as documented by several follow-up studies both including or not control groups of non-infected children. However, the methodological variabilities of the analyzed studies does not allow to provide firm conclusions about the rate, type and best diagnostics for children with persistent respiratory symptoms. Future studies should investigate on larger pediatric cohorts the role of noninvasive diagnostics and new biomarkers as well as investigating therapeutic options both during acute infection or when Long Covid has been diagnosed.

Abstract
BACKGROUND Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes an acute respiratory illness. A substantial proportion of adults experience persistent symptoms. There is a paucity of data on respiratory sequelae in children. Exhaled breath condensate (EBC) is a non-invasive tool used to assess airway inflammation. OBJECTIVES This study aimed to evaluate EBC parameters, respiratory, mental and physical ability among children post COVID-19 infection. METHODS Observational study of confirmed SARS-CoV-2 infection cases among children, aged 5-18 years, evaluated once, 1-6 months post positive SARS-CoV-2 PCR testing. All subjects performed spirometry, 6-min walk test (6MWT), EBC (pH, interleukin-6), and completed medical history questionnaires, Depression, Anxiety, and Stress Scale (DASS-21), and physical activity scores. Severity of COVID-19 disease was classified according to WHO criteria. RESULTS Fifty-eight children were included and classified asymptomatic (n = 14), mild (n = 37), and moderate (n = 7) disease. The asymptomatic group included younger patients compared to the mild and moderate groups (8.9 ± 2.5y vs. 12.3 ± 3.6y and 14.6 ± 2.5y, respectively, p = 0.001), as well as lower DASS-21 total scores (3.4 ± 4 vs. 8.7 ± 9.4 and 8.7 ± 0.6 respectively, p = 0.056), with higher scores in proximity to positive PCR (p = 0.011). No differences were found between the 3 groups regarding EBC, 6MWT, spirometry, body mass index percentile, and activity scores. CONCLUSIONS COVID-19 is an asymptomatic-mild disease in most young healthy children, with gradually diminishing emotional symptoms. Children without prolonged respiratory symptoms revealed no significant pulmonary sequelae as evaluated by EBC markers, spirometry, 6MWT, and activity scores. Larger studies are required to assess long-term pediatric consequences of post SARS-CoV-2 infection, to assess the need for pulmonology surveillance.

Abstract
BACKGROUND Coronavirus disease 2019 (COVID-19) has rapidly spread worldwide and is characterized by different presentations ranging from asymptomatic to severe pneumonia. COVID-19 affects all age groups, including pediatric patients. We observed numerous children complaining of a cough post-COVID-19, even if it was trivial. The most reported persistent symptoms after recovery from COVID-19 were insomnia, coughing, fatigue, dyspnea, loss of taste and/or smell, and headache. To date, residual cough post-COVID-19 has been reported in pediatrics and adolescents. METHOD we conducted a retrospective study, with a self-administered questionnaire by the patient or caregiver, 12 months post-COVID-19-infection. RESULT A total of 94.8% of patients were Saudi citizens and were mainly from the southern region of Saudi Arabia (50.0%). Mothers (64.4%) submitted most of the results. The ages were as follows: 6-14 years (51.0%), 3-5 years (32.3%), and younger than 2 years of age (only 16.7%). Females accounted for 41.7% of those studied. Nearly half of the patients (48.5%) had had a previous COVID-19 infection in 2022, with only 2.1% infected in 2019. Only 27/194 (13.9%) patients required hospital admission, and 7 of them (4.2%) required intensive care treatment. A total of 179 (92.2%) patients still reported persistent symptoms 4 weeks post-COVID-19-infection. A cough was reported in 69.8% of patients, followed by cough and wheezing in 12.3%. The cough was described as dry in 78.0% and nocturnal in 54.1%, while 42.5% did not notice any diurnal variation. For those reporting residual cough, 39.3% found that it affected school attendance and daily activities, 31.1% reported associated chest pain, 51.9% associated it with wheezing, and 27.1% associated it with shortness of breath. For 54.4%, the residual cough lasted less than one month, while 31.4% reported a 1-2 month duration. Only 1.0% had a duration of cough of more than 3 months. For cough relief, 28.2% used bronchodilators, 19.9% used cough syrup, 16.6% used a combination of bronchodilators and steroid inhalers, and 1.7% used antibiotics. Surprisingly, 33% attempted herbal remedies for cough relief. Sesame oil was used the most (40.0%), followed by a mixture of olive oil and sesame oil (25.0%), and 21.7% used male frankincense. The majority (78.4%) sought medical advice for their post-infection cough, either from general pediatricians (39.5%) or via specialist pediatric pulmonology consultations (30.9%). A total of 11.0% with a residual cough reported having pets at home, while 27.2% reported secondhand smoke exposure in the household. Before infection with COVID-19, only 32.6% were diagnosed with asthma, while 68.2% reported a diagnosis of atopic skin. CONCLUSIONS There was a high prevalence of residual cough post-COVID-19, extended for a minimum of two months, and the characteristics of the cough were very similar to those of asthmatic patients. There was still a high prevalence of using cough syrup and herbal remedies, especially olive oil, sesame oil, and male frankincense. A residual cough adversely affected school attendance in daily activities, and there was a high prevalence of other siblings in the family being affected. The study showed that a minority of patients were seen by the pulmonologist; luckily, long COVID was rare in our study, and so further studies are highly needed to confirm the association with asthma. More educational programs are highly needed regarding herbal remedies and cough syrup.

Abstract
Long COVID syndrome has emerged as a long-lasting consequence of acute SARS-CoV-2 infection in adults. In addition, children may be affected by Long COVID, with potential clinical issues in different fields, including problems in school performance and daily activities. Yet, the pathophysiologic bases of Long COVID in children are largely unknown, and it is difficult to predict who will develop the syndrome. In this multidisciplinary clinical review, we summarise the latest scientific data regarding Long COVID and its impact on children. Special attention is given to diagnostic tests, in order to help the physicians to find potential disease markers and quantify impairment. Specifically, we assess the respiratory, upper airways, cardiac, neurologic and motor and psychological aspects. Finally, we also propose a multidisciplinary clinical approach.

Abstract
BACKGROUND Data regarding kinetics of anti-SARS-CoV-2 antibody and information about long COVID in children are scarce, especially in developing countries. Even though cases of COVID-19 in children are less prevalent than adults, the long COVID cases in children are high and have a burden that may impact their growth and development. There are other features of antibody kinetics in connection with SARS-CoV-2 infection that are yet unknown as of this writing, especially in children following the infection. Furthermore, the long-term results, risk factors, and the underlying pathophysiology are still uncertain. To better understand long COVID in children, it is necessary to further investigate the impact of significant clinical factors such multisystem inflammatory syndrome and disease severity among hospitalized survivors with their SARS-CoV-2 antibody response. OBJECTIVE We aimed to analyze anti RBD SARS-CoV-2 IgG antibodies over time and characterize long COVID signs and symptoms in pediatric patients at the time of diagnosis, two weeks, one, three-, and six-months following infection. METHODS This is a longitudinal observational study which was approved by the Medical and Health Research Ethics Committee (MHREC) Faculty of Medicine, Public Health and Nursing UGM (KE/FK/1288/EC/2021). Pediatric patients diagnosed with COVID-19 by positive molecular assay in nasopharyngeal swab will be tested for anti-SARS-CoV-2 antibodies using the Roche Elecsys anti-SARS-CoV-2 S assay at the time of diagnosis, two weeks, one, three-, and six-months following infection. Antibody titer data will be reported as mean and standard deviation. The respondents' signs and symptoms will be observed up to 6 months after the onset of infection, including the vaccination event, re-infection, re-hospitalization and mortality. The clinical features will be reported in frequency and percentage. RESULTS The funding was obtained in September 2021, and participant enrollment began from February 2022. Results analysis are expected by November 2022. CONCLUSIONS This study will allow us to know the kinetics of anti-RBD SARS-CoV-2 IgG antibodies and data regarding long COVID up to 6 months following infection in the Indonesian pediatric population. This study furthermore has the potential to be a basis for the government to decide on terms of vaccine programs and mitigation strategies.

The outcomes of COVID-19 pneumonia in children-clinical, radiographic, and pulmonary function assessment. Pediatr Pulmonol 2023; 58:1042-1050. [PMID: 36562653 PMCID: PMC9880754 DOI: 10.1002/ppul.26291] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/29/2022] [Revised: 12/15/2022] [Accepted: 12/20/2022] [Indexed: 12/24/2022]
Abstract
OBJECTIVES The goal of this study was to assess the pulmonary sequelae of COVID-19 pneumonia in children. STUDY DESIGN Children (0-18 years old) diagnosed with COVID-19 pneumonia hospitalized between March 2020 and March 2021 were included in this observational study. All children underwent follow-up visits 3 months postdischarge, and if any abnormalities were stated, a second visit after the next 3 months was scheduled. Clinical assessment included medical history, physical examination, lung ultrasound (LUS) using a standardized protocol, and pulmonary function tests (PFTs). PFTs results were compared with healthy children. RESULTS Forty-one patients with COVID-19 pneumonia (severe disease n = 3, mechanical ventilation, n = 0) were included in the study. Persistent symptoms were reported by seven (17.1%) children, the most common was decreased exercise tolerance (57.1%), dyspnea (42.9%), and cough (42.9%). The most prevalent abnormalities in LUS were coalescent B-lines (37%) and small subpleural consolidations (29%). The extent of LUS abnormalities was significantly greater at the first than at the second follow-up visit (p = 0.03). There were no significant differences in PFTs results neither between the study group and healthy children nor between the two follow-up visits in the study group. CONCLUSIONS Our study shows that children might experience long-term sequelae following COVID-19 pneumonia. In the majority of cases, these are mild and resolve over time.

Duration of clinical symptoms in children with acute respiratory infection. Acta Paediatr 2023; 112:813-819. [PMID: 36427274 DOI: 10.1111/apa.16607] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/14/2022] [Revised: 11/07/2022] [Accepted: 11/24/2022] [Indexed: 11/26/2022]
Abstract
AIM To investigate duration of clinical symptoms associated with various respiratory viruses and with the co-detection of respiratory viral and bacterial pathogens. METHODS This prospective cohort study included 737 acutely ill children treated in a paediatric emergency department prior to the COVID-19 pandemic. Nasal swab samples were analysed with multiplex PCR panels for 16 viral and 7 bacterial respiratory pathogens. Parents filled in a questionnaire about the symptoms at the time of the visit and 14 days afterwards. RESULTS Persistent symptoms 2 weeks after the onset of acute illness were common: 32% of the patients with a coronavirus 229 E, NL63 or OC43 finding, 31% of those with human metapneumovirus and 25% of those with rhinovirus reported ongoing symptoms. At least one symptom lasting more than 4 weeks was observed in 3-4% of the children. Children with viral and bacterial co-detection had a longer duration of fever than those with only viral detection (3.3 days [SD 2.8] vs. 1.6 days [SD 2.4], p < 0.001). CONCLUSION Symptoms lasting for more than 2 to 4 weeks appear to be relatively frequent in all respiratory viral infections in children. Viral and bacterial co-detection may increase the duration of illness.

Cognition and Mental Health in Pediatric Patients Following COVID-19. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2023; 20:5061. [PMID: 36981968 PMCID: PMC10049312 DOI: 10.3390/ijerph20065061] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/06/2023] [Revised: 02/28/2023] [Accepted: 03/12/2023] [Indexed: 06/18/2023]
Abstract
The global coronavirus pandemic has significantly impacted public health and has been a research subject since its emergence in 2019. The acute phase of the disease leads to pulmonary and non-pulmonary manifestations, which in some individuals may progress to long-lasting symptoms. In this article, we conducted a narrative review of the current literature to summarize current knowledge regarding long COVID syndrome in children, focusing on cognitive symptoms. The review included a search of three databases (PubMed, Embase, and Web of Science) using the key phrases "post COVID-19 cognitive pediatric", "long COVID pediatric", "mental health long COVID children", and "COVID-19 cognitive symptoms". A total of 102 studies were included. The review revealed that the main long-term cognitive symptoms following COVID-19 were memory and concentration deficits, sleep disturbances, and psychiatric states such as anxiety and stress. In addition to the direct physiological effects of a viral infection, there are psychological, behavioral, and social factors contributing to cognitive impairment, which should be addressed regarding the pediatric population. The high prevalence of neurocognitive symptoms in children following COVID-19 emphasizes the importance of understanding the mechanisms of nervous system involvement.

Prevalence and risk factor for long COVID in children and adolescents: A meta-analysis and systematic review. J Infect Public Health 2023; 16:660-672. [PMID: 36931142 PMCID: PMC9990879 DOI: 10.1016/j.jiph.2023.03.005] [Citation(s) in RCA: 26] [Impact Index Per Article: 26.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2022] [Revised: 01/09/2023] [Accepted: 03/05/2023] [Indexed: 03/09/2023] Open
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, and Cochrane Library 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]). Dyspnea (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.

Mental health among children with long COVID during the COVID-19 pandemic. Eur J Pediatr 2023; 182:1793-1801. [PMID: 36786887 PMCID: PMC9925927 DOI: 10.1007/s00431-023-04854-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/26/2022] [Revised: 12/13/2022] [Accepted: 01/31/2023] [Indexed: 02/15/2023]
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.

Prevalence of mental health problems among children with long COVID: A systematic review and meta-analysis. PLoS One 2023; 18:e0282538. [PMID: 37195978 DOI: 10.1371/journal.pone.0282538] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2022] [Accepted: 02/16/2023] [Indexed: 05/19/2023] Open
Abstract
INTRODUCTION The number of children with mental health problems has more than doubled since the COVID-19 pandemic. However, the effect of long Covid on children's mental health is still debatable. Recognising long Covid as a risk factor for mental health problems in children will increase awareness and screening for mental health problems following COVID-19 infection, resulting in earlier intervention and lower morbidity. Therefore, this study aimed to determine the proportion of mental health problems post-COVID-19 infection in children and adolescents, and to compare them with the population with no previous COVID-19 infection. METHODOLOGY A systematic search was done in seven databases using pre-defined search terms. Cross-sectional, cohort and interventional studies reporting the proportion of mental health problems among children with long COVID in the English language from 2019 to May 2022 were included. Selection of papers, extraction of data and quality assessment were done independently by two reviewers. Studies with satisfactory quality were included in meta-analysis using R and Revman software programmes. RESULTS The initial search retrieved 1848 studies. After screening, 13 studies were included in the quality assessments. Meta-analysis showed children who had previous COVID-19 infection had more than two times higher odds of having anxiety or depression, and 14% higher odds of having appetite problems, compared to children with no previous infection. The pooled prevalence of mental health problems among the population were as follows; anxiety: 9%(95% CI:1, 23), depression: 15%(95% CI:0.4, 47), concentration problems: 6%(95% CI: 3, 11), sleep problems: 9%(95% CI:5, 13), mood swings: 13% (95%CI:5, 23) and appetite loss: 5%(95% CI:1, 13). However, studies were heterogenous and lack data from low- and middle-income countries. CONCLUSION Anxiety, depression and appetite problems were significantly increased among post-COVID-19 infected children, compared to those without a previous infection, which may be attributed to long COVID. The findings underscore the importance of screening and early intervention of children post-COVID-19 infection at one month and between three to four months.

Cardiac Involvement in Children Affected by COVID-19: Clinical Features and Diagnosis. Diagnostics (Basel) 2022; 13:diagnostics13010120. [PMID: 36611412 PMCID: PMC9818331 DOI: 10.3390/diagnostics13010120] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2022] [Revised: 12/24/2022] [Accepted: 12/26/2022] [Indexed: 12/31/2022] Open
Abstract
COVID-19 (Coronavirus disease 2019) in children is usually mild. However, multiple organ disorders associated with SARS-CoV-2 (severe acute respiratory syndrome-related coronavirus 2) have been detected with poor respiratory symptoms. Cardiac changes are noted in 17% to 75% of cases, which are associated with diagnostic difficulties in high-risk groups for the development of complications that are associated with myocardial damage by the SARS-CoV-2 virus. The objective of this review is to identify the most significant symptoms of cardiac involvement affected by COVID-19, which require in-depth examination. The authors analyzed publications from December 2019 to the October 2022, which were published in accessible local and international databases. According to the analysis data, the main sign of myocardial involvement was increasing as cardiomarkers in the patient's blood, in particular troponin I or troponin T. Many authors noted that the increased level of CRP (C-reactive protein) and NT-proBNP, which are accompanied by changes in the ECG (electrocardiogram) and EchoCG (echocardiography), as a rule, were nonspecific. However, the identified cardiac functional dysfunctions affected by SARS-CoV-2, required an cardiac MRI. The lack of timely diagnosis of myocardial involvements, especially in children at high risk for the development of complications associated with SARS-CoV-2 myocardial injury, can lead to death. The direct damage of the structural elements of myocardial blood vessels in patients with severe hypoxic changes resulted from respiratory failure caused by SARS-CoV-2 lung damage, with the development of severe acute diffuse alveolar damage and cell-mediated immune response and myocardial involvement affected by SARS-CoV-2 damage. In this article, the authors introduce a clinical case of a child who dead from inflammatory myocardities with COVID-19 in a background of congenital heart disease and T-cell immunodeficiency.

Long-Term Effect of COVID-19 on Lung Imaging and Function, Cardiorespiratory Symptoms, Fatigue, Exercise Capacity, and Functional Capacity in Children and Adolescents: A Systematic Review and Meta-Analysis. Healthcare (Basel) 2022; 10:healthcare10122492. [PMID: 36554016 PMCID: PMC9778658 DOI: 10.3390/healthcare10122492] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2022] [Revised: 11/29/2022] [Accepted: 12/05/2022] [Indexed: 12/14/2022] Open
Abstract
BACKGROUND The long-term sequela of COVID-19 on young people is still unknown. This systematic review explored the effect of COVID-19 on lung imaging and function, cardiorespiratory symptoms, fatigue, exercise capacity and functional capacity in children and adolescents ≥ 3 months after infection. METHODS A systemic search was completed in the electronic databases of PubMed, Web of Science and Ovid MEDLINE on 27 May 2022. Data on the proportion of participants who had long-term effects were collected, and one-group meta-analysis were used to estimate the pooled prevalence of the outcomes studied. RESULTS 17 articles met the inclusion criteria, presented data on 124,568 children and adolescents. The pooled prevalence of abnormalities in lung imaging was 10% (95% CI 1-19, I2 = 73%), abnormal pulmonary function was 24% (95% CI 4-43, I2 = 90%), chest pain/tightness was 6% (95% CI 3-8, I2 = 100%), heart rhythm disturbances/palpitations was 6% (95% CI 4-7, I2 = 98%), dyspnea/breathing problems was 16% (95% CI 14-19, I2 = 99%), and fatigue was 24% (95% CI 20-27, I2 = 100%). Decreased exercise capacity and functional limitations were found in 20% (95% CI 4-37, I2 = 88%) and 48% (95% CI 25-70, I2 = 91%) of the participants studied, respectively. CONCLUSION Children and adolescents may have persistent abnormalities in lung imaging and function, cardiorespiratory symptoms, fatigue, and decreased functional capacity between 3 to 12 months after infection. More research is needed to understand the long-term effect of COVID-19 on young people, and to clarify its causes and effective management.

Abstract
While most children with coronavirus 2019 (COVID-19) experience mild illness, some are vulnerable to severe disease and develop long-term complications. Children with disabilities, those from lower-income homes, and those from racial and ethnic minority groups are more likely to be hospitalized and to have poor outcomes following an infection. For many of these same children, a wide range of social, economic, and environmental disadvantages have made it more difficult for them to access COVID-19 vaccines. Ensuring vaccine equity in children and decreasing health disparities promotes the common good and serves society as a whole. In this article, we discuss how the pandemic has exposed long-standing injustices in historically marginalized groups and provide a summary of the research describing the disparities associated with COVID-19 infection, severity, and vaccine uptake. Last, we outline several strategies for addressing some of the issues that can give rise to vaccine inequity in the pediatric population.

Clinical assessment of children with long COVID syndrome. Pediatr Res 2022; 93:1616-1625.

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.

Prevalence and clinical presentation of long COVID in children: a systematic review. Eur J Pediatr 2022; 181:3995-4009. [PMID: 36107254 PMCID: PMC9476461 DOI: 10.1007/s00431-022-04600-x] [Citation(s) in RCA: 39] [Impact Index Per Article: 19.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/16/2021] [Revised: 08/04/2022] [Accepted: 08/20/2022] [Indexed: 11/03/2022]
Abstract
A systematic literature review was conducted up to 15th February 2022 to summarize long COVID evidence and to assess prevalence and clinical presentation in children and adolescents. Articles reporting long COVID prevalence and symptoms based on original data in the paediatric population were included. Case series quality was assessed through the JBI Critical Appraisal Checklist. For observational studies, adherence to STROBE checklist was evaluated. Twenty-two articles were included: 19 observational studies (12 cohort/7 cross-sectional) and 3 case series. Nine studies provided a control group. We found a high variability in terms of prevalence (1.6-70%). The most frequently reported symptoms were fatigue (2-87%), headache (3.5-80%), arthro-myalgias (5.4-66%), chest tightness or pain (1.4-51%), and dyspnoea (2-57.1%). Five studies reported limitations in daily function due to long COVID. Alterations at brain imaging were described in one study, transient electrocardiographic abnormalities were described in a minority of children, while most authors did not evidence long-term pulmonary sequelae. Older age, female sex, and previous long-term pathological conditions were more frequently associated with persistent symptoms. CONCLUSION Long COVID evidence in children is limited, heterogeneous, and based on low-quality studies. The lockdown consequences are difficult to distinguish from long COVID symptoms. High-quality studies are required: WHO definition of long COVID should be used, controlled clinical studies should be encouraged, and the impact of new variants on long COVID prevalence should be investigated to ensure an objective analysis of long COVID characteristics in children and a proper allocation of healthcare system resources. WHAT IS KNOWN • Children rarely develop a severe respiratory disease in the acute phase of COVID-19. • A limited number of patients develop a multisystem inflammatory condition that can lead to multiorgan failure and shock. WHAT IS NEW • Persistent symptoms after SARS-CoV-2 infection are reported in children and limitations in daily function due to long COVID symptoms affect school attendance. • Functional complaints of post-acute COVID are difficult to be distinguished from those due to social restrictions.

Abstract
COVID-19 was primarily considered a pulmonary disease with extrapulmonary manifestations. As the pandemic spread, there has been growing evidence that the disease affects various organs/systems, including the central and peripheral nervous systems. Accumulation of clinical data demonstrates that in a large population of survivors impairments in the function of one or more organs may persist for a long time, a phenomenon commonly known as post COVID or long COVID. Fatigue and cognitive dysfunction, such as concentration problems, short-term memory deficits, general memory loss, a specific decline in attention, language and praxis abilities, encoding and verbal fluency, impairment of executive functions, and psychomotor coordination, are amongst the most common and debilitating features of neuropsychatric symptoms of post COVID syndrome. Several patients also suffer from compromised sleep, depression, anxiety and post-traumatic stress disorder. Patients with long COVID may demonstrate brain hypometabolism, hypoperfusion of the cerebral cortex and changes in the brain structure and functional connectivity. Children and adolescents represent a minority of COVID-19 cases, so not surprisingly data on the long-term sequelae after SARS-CoV-2 infections in these age groups are scarce. Although the pathogenesis, clinical characteristics, epidemiology, and risk factors of the acute phase of COVID-19 have been largely explained, these areas are yet to be explored in long COVID. This review aims to provide an update on what is currently known about long COVID effects on mental health.

Abstract
The novel SARS-CoV-2 coronavirus infection is predominantly asymptomatic or presenting few symptoms in children, and life-threatening complications are rare. In most cases, symptoms of ARVI are observed, such as fever, cough, myalgia, or weakness, which are milder than in adult patients. In addition, most laboratory and radiographic findings in children with COVID-19 are nonspecific. However, some children may develop prolonged forms of COVID-19, as well as long-term symptoms (post-COVID syndrome) after the illness, which significantly affect the quality of life. There are different data regarding the prevalence and duration of long-term effects of a new coronavirus infection in children. The most common symptoms following COVID-19 in children/teens are fatigue, lack of concentration, and muscle pain. The review presents the latest literature data on the duration and course of COVID-19 in children. It should be remembered that long-term symptoms could affect the physical, social, and psychological well-being of children and adolescents in the future.

Abstract
Although children have been largely spared the most severe consequences of acute infection with SARS-CoV-2 virus, it is estimated that up to one-quarter of the more than 14 million children diagnosed as having coronavirus disease 2019 (COVID-19) have developed persistent symptoms of fatigue, postexertional malaise, neurologic and cognitive symptoms, and other symptoms that interfere with activities of daily living for months after their initial illness. Pediatric postacute sequelae of COVID-19 (pPASC), or long-COVID, is a complex, heterogeneous, postviral condition involving multiple body systems and is likely attributable to several concurrent underlying physiologic processes, including damage from direct viral invasion, endovascular dysfunction and microthrombosis, viral persistence, and the development of autoimmunity. In this review, we explore the current state of the literature regarding definition, epidemiology, clinical presentation, and proposed pathophysiologic mechanisms of pPASC.

Abstract
BACKGROUND We aimed to elucidate variables associated with coronavirus disease 2019 (COVID-19) vaccine compliance in adolescents and devise targeted interventions. Our secondary aim was to compare the rates of severe acute respiratory syndrome coronavirus 2 infection, hospitalizations and deaths between vaccinated and unvaccinated adolescents. METHODS A retrospective review of electronic medical records was performed on all adolescents 12-17 years of age registered at Clalit Health District in Israel during January 1, 2021, to November 18, 2021, with characterization by vaccination status against COVID-19. Univariate and multivariable analyses were employed to identify predictors of vaccination. RESULTS Of the 43,919 subjects included in the study, 28,207 (64.2%) were vaccinated. Non-ultraorthodox Jewish adolescents had a higher vaccination rate than the minorities Arabs or ultraorthodox Jews (72.5%, 66.2% and 40.5%, respectively, P < 0.001). Adolescents of high socioeconomic status had nearly 2-fold higher vaccination rates than those of low socioeconomic status (80.4% vs 42.3%; P < 0.0001). Adolescents 16-17 years old had a higher rate of COVID-19 vaccination than those 12-15 years old (72.5% vs 60.6%, P < 0.001), as were girls versus boys (64.7% vs 63.8%, P = 0.047). Multivariate analysis identified 3 independent variables that were significantly ( P < 0.001) associated with low vaccination: ultraorthodox sector, Arab population, and underlying obesity (hazard rations 0.42, 0.72 and 0.84, respectively). Vaccination was significantly associated with reduced severe acute respiratory syndrome coronavirus 2 infection, hospitalization and death ( P < 0.001). CONCLUSION This study highlights several pediatric populations with low COVID-19 vaccine compliance. Targeted interventions aimed at these populations are suggested with consideration of their special cultural, social and societal characteristics.

Clinical Features and Burden of Postacute Sequelae of SARS-CoV-2 Infection in Children and Adolescents. JAMA Pediatr 2022; 176:1000-1009. [PMID: 35994282 PMCID: PMC9396470 DOI: 10.1001/jamapediatrics.2022.2800] [Citation(s) in RCA: 47] [Impact Index Per Article: 23.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/07/2022] [Accepted: 06/08/2022] [Indexed: 01/20/2023]
Abstract
Importance The postacute sequelae of SARS-CoV-2 infection (PASC) has emerged as a long-term complication in adults, but current understanding of the clinical presentation of PASC in children is limited. Objective To identify diagnosed symptoms, diagnosed health conditions, and medications associated with PASC in children. Design, Setting and Participants This retrospective cohort study used electronic health records from 9 US children's hospitals for individuals younger than 21 years who underwent antigen or reverse transcriptase-polymerase chain reaction (RT-PCR) testing for SARS-CoV-2 between March 1, 2020, and October 31, 2021, and had at least 1 encounter in the 3 years before testing. Exposures SARS-CoV-2 positivity by viral test (antigen or RT-PCR). Main Outcomes and Measures Syndromic (symptoms), systemic (conditions), and medication PASC features were identified in the 28 to 179 days following the initial test date. Adjusted hazard ratios (aHRs) were obtained for 151 clinically predicted PASC features by contrasting viral test-positive groups with viral test-negative groups using proportional hazards models, adjusting for site, age, sex, testing location, race and ethnicity, and time period of cohort entrance. The incidence proportion for any syndromic, systemic, or medication PASC feature was estimated in the 2 groups to obtain a burden of PASC estimate. Results Among 659 286 children in the study sample, 348 091 (52.8%) were male, and the mean (SD) age was 8.1 (5.7) years. A total of 59 893 (9.1%) tested positive by viral test for SARS-CoV-2, and 599 393 (90.9%) tested negative. Most were tested in outpatient testing facility settings (322 813 [50.3%]) or office settings (162 138 [24.6%]). The most common syndromic, systemic, and medication features were loss of taste or smell (aHR, 1.96; 95% CI, 1.16-3.32), myocarditis (aHR, 3.10; 95% CI, 1.94-4.96), and cough and cold preparations (aHR, 1.52; 95% CI, 1.18-1.96), respectively. The incidence of at least 1 systemic, syndromic, or medication feature of PASC was 41.9% (95% CI, 41.4-42.4) among viral test-positive children vs 38.2% (95% CI, 38.1-38.4) among viral test-negative children, with an incidence proportion difference of 3.7% (95% CI, 3.2-4.2). A higher strength of association for PASC was identified in those cared for in the intensive care unit during the acute illness phase, children younger than 5 years, and individuals with complex chronic conditions. Conclusions and Relevance In this large-scale, exploratory study, the burden of pediatric PASC that presented to health systems was low. Myocarditis was the most commonly diagnosed PASC-associated condition. Acute illness severity, young age, and comorbid complex chronic disease increased the risk of PASC.

The CSHQ-DE Questionnaire Uncovers Relevant Sleep Disorders in Children and Adolescents with Long COVID. CHILDREN 2022; 9:children9091419. [PMID: 36138727 PMCID: PMC9497557 DOI: 10.3390/children9091419] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/30/2022] [Revised: 09/09/2022] [Accepted: 09/14/2022] [Indexed: 11/19/2022]
Abstract
Acute SARS-CoV-2 infections in children and adolescents are usually mild. However, they can suffer from ongoing symptoms, generally referred to as long COVID. Sleep disorders are one of the most frequent complaints in long COVID although precise data are missing. We assessed the sleep behavior of children and adolescents who presented at our outpatient clinic between January 2021 and May 2022 with the Children’s Sleep Habits Questionnaire (CSHQ-DE). We compared the sleep behavior at three different time points: pre-COVID-19; post-COVID-19 at the initial presentation; and post-COVID-19 at re-presentation. Data from 45 patients were analyzed. Of those, 64% were female and the median age was 10 years (range: 0–18 years). Asymptomatic or mild COVID-19 disease was experienced in 89% of patients; 11% experienced moderate disease. The initial presentation occurred at a median of 20.4 weeks (6 weeks–14 months) after the infection. The CSHQ-DE score increased significantly from pre-COVID-19 (45.82 ± 8.7 points) to post-COVID-19 (49.40 ± 8.3 points; p ≤ 0.01). The score then normalized at re-presentation (46.98 ± 7.8; p = 0.1). The greatest changes were seen in the CSHQ-DE subscale score “daytime sleepiness”. Our data showed that children and adolescents with long COVID often suffer from sleep disturbances. For most children and adolescents, these sleep disorders decreased over time without any further medical intervention aside from a basic sleep consultation.

Neurological and psychological effects of long COVID in a young population: A cross-sectional study. Front Neurol 2022; 13:925144. [PMID: 36062008 PMCID: PMC9428748 DOI: 10.3389/fneur.2022.925144] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2022] [Accepted: 07/21/2022] [Indexed: 11/13/2022] Open
Abstract
Aim We evaluated the long-term clinical status of pediatric patients after testing positive for COVID-19. We hypothesized that there are similar symptoms to those that have been described in adults and children and that pediatric patients with neurophysiologic symptoms still present 3–5 months after infection have psychological consequences that interfere with their adaptive functioning. Method We recruited 322 COVID-19-positive pediatric patients, between 1.5 and 17 years old, from the outpatient clinic for COVID-19 follow-up. Neurological symptoms were analyzed at onset, after 1 month, and after 3–5 months. A psychological assessment with standardized questionnaires was also conducted to determine the impact of the disease. Results At the onset of COVID-19, 60% of the total sample exhibited symptoms; this decreased after 1 month (20%) but stabilized 3–5 months after disease onset (22%). Prevailing long-COVID neurological symptoms were headache, fatigue, and anosmia. In the 1.5–5-year-old subgroup, internalizing problems emerged in 12% of patients. In the 6–18-year-old subgroup, anxiety and post-traumatic stress showed significant associations with neurological symptoms of long COVID. Conclusions These data demonstrate that long COVID presents various broad-spectrum symptoms, including psychological and long-lasting cognitive issues. If not treated, these symptoms could significantly compromise the quality of life of children and adolescents.

Abstract
Neurological manifestations of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in children are becoming increasingly apparent as the coronavirus disease (COVID-19) pandemic continues. While children manifest relatively milder features of the disease, accumulating evidence warrants concern that COVID-19 exacts both acute- and long-term effects on the developing central and peripheral nervous systems. This review focuses on the relatively underinvestigated topic of the effects of SARS-CoV-2 on the brain in infancy and childhood, concluding that clinicians should be attentive to both the acute effects and long-term consequences of COVID-19 from a neurological perspective.

Abstract
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections in children generally have milder presentations, but severe disease can occur in all ages. MIS-C and persistent post-acute COVID-19 symptoms can be experienced by children with previous infection and emphasize the need for infection prevention. Optimal treatment for COVID-19 is not known, and clinical trials should include children to guide therapy. Vaccines are the best tool at preventing infection and severe outcomes of COVID-19. Children suffered disproportionately during the pandemic not only from SARS-CoV-2 infection but because of disruptions to daily life, access to primary care, and worsening income inequalities.
