International Care programs for Pediatric Post-COVID Condition (Long COVID) and the way forward

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.

Thyroid disturbances after COVID-19 and the effect of vaccination in children: a prospective tri-center registry analysis

Rapidly evolving clinical data suggest that the novel coronavirus (SARS-CoV-2) and vaccination against COVID-19 might be associated with thyroid disturbances. However, studies remain limited among the pediatric population. Our aim was to assess the prevalence and permanence of thyroid autoimmunity (TA) and dysfunction in children after an acute infection and its potential association with vaccination. A prospective, multicenter registry analysis was performed among 458 children (mean age: 12.4 ± 3,8 years, 45.4% male) with preceding COVID-19. Patient inclusion lasted from 24th March, 2021 to 23rd March, 2022 at three pediatric outpatient facilities at Semmelweis University, Budapest. Primary outcomes were the rate of thyroid disturbances assessed by laboratory parameters (thyroid function tests, antithyroglobulin [ATG] and anti-thyroid peroxidase [ATPO] antibodies) and thyroid ultrasound. TA rate among vaccinated and unvaccinated children was determined. Children with newly diagnosed thyroid alterations were followed up for 12.7 ± 4.3 months. Six children had previous thyroid disease. Out of 452 children, 30 cases (6.6%) of newly diagnosed TA (six of them had abnormal thyroid-stimulating hormone [TSH] levels) and eight cases (1.8%) of isolated TSH elevation were observed. Ultrasound-proven autoimmune thyroiditis (AIT) was 4.0%. No association was found between COVID-19 vaccination and thyroid autoimmunity (χ2(1,N = 452) = 0.138, p = 0.815). Among children with TA, 73.3% had long-lasting alterations.  Conclusion: Vaccination had no effect on the prevalence of TA. Until further controlled studies state otherwise, children with preceding COVID-19 might benefit from thyroid screening. What is Known: • Numerous case reports implicate that coronavirus disease-2019 (COVID-19) and vaccination against SARS-CoV-2 can be responsible for thyroid disturbances. • Thyroid alterations discovered during acute COVID-19 tend to cease by time and only incidental thyroid autoimmunity (TA) is diagnosed after COVID-19. In adults, no increase in vaccine-related hyper- or hypothyroidism was found. What is New: • TA rate after COVID-19 vaccination among children was not increased. TA had no role in long COVID syndrome. • We discovered a considerable rate of TA (6.6%) and ultrasound-proven autoimmune thyroiditis (AIT) (4.0%) after SARS-CoV-2 infection, and the majority of these alterations remained positive after 6 months.

The COVID-19 Pandemic Affects Seasonality, With Increasing Cases of New-Onset Type 1 Diabetes in Children, From the Worldwide SWEET Registry

OBJECTIVE

To analyze whether the coronavirus disease 2019 (COVID-19) pandemic increased the number of cases or impacted seasonality of new-onset type 1 diabetes (T1D) in large pediatric diabetes centers globally.

RESEARCH DESIGN AND METHODS

We analyzed data on 17,280 cases of T1D diagnosed during 2018-2021 from 92 worldwide centers participating in the SWEET registry using hierarchic linear regression models.

RESULTS

The average number of new-onset T1D cases per center adjusted for the total number of patients treated at the center per year and stratified by age-groups increased from 11.2 (95% CI 10.1-12.2) in 2018 to 21.7 (20.6-22.8) in 2021 for the youngest age-group, <6 years; from 13.1 (12.2-14.0) in 2018 to 26.7 (25.7-27.7) in 2021 for children ages 6 to <12 years; and from 12.2 (11.5-12.9) to 24.7 (24.0-25.5) for adolescents ages 12-18 years (all P < 0.001). These increases remained within the expected increase with the 95% CI of the regression line. However, in Europe and North America following the lockdown early in 2020, the typical seasonality of more cases during winter season was delayed, with a peak during the summer and autumn months. While the seasonal pattern in Europe returned to prepandemic times in 2021, this was not the case in North America. Compared with 2018-2019 (HbA1c 7.7%), higher average HbA1c levels (2020, 8.1%; 2021, 8.6%; P < 0.001) were present within the first year of T1D during the pandemic.

CONCLUSIONS

The slope of the rise in pediatric new-onset T1D in SWEET centers remained unchanged during the COVID-19 pandemic, but a change in the seasonality at onset became apparent.

Anti-SARS-CoV-2 Seropositivity Among Children With Newly Diagnosed Type 1 Diabetes Mellitus: A Case-Control Study

A sudden increase in the number of children with newly diagnosed type 1 diabetes mellitus (T1DM) was experienced during the third wave of COVID-19 epidemic in Hungary. The newly diagnosed T1DM patients had a significantly higher rate of anti-SARS-CoV-2 positivity as compared to prevalent T1DM children [OR (95% CI) 3.74 (1,08,13.55); P=0.04]. The relationship between SARS-CoV-2 infection and diabetes needs to be investigated further.

Transitional elevation of anti-tissue transglutaminase antibodies in children with type 1 diabetes mellitus without coeliac disease

Összefoglaló. Bevezetés: Az 1-es típusú diabetes mellitus és a coeliakia gyakori társulása jól ismert. Néhány tanulmány beszámol átmeneti antitranszglutamináz-emelkedésről 1-es típusú diabeteses betegekben, akiknél az emelkedett antitestszint gluténmentes diéta bevezetése nélkül normalizálódik. Célkitűzés: Kutatásunk során az átmeneti antitranszglutamináz-emelkedés gyakoriságának meghatározását tűztük ki célul. További célunk volt a coeliakia gyakoriságának megállapítása 1-es típusú diabetesszel gondozott betegeink között. Módszer: A Semmelweis Egyetem I. Gyermekgyógyászati Klinikáján 1-es típusú diabetesszel gondozott betegeket vontuk be vizsgálatunkba (238 lány, 265 fiú, medián [IR] életkor az 1-es típusú diabetes diagnózisakor: 7,83 [4,67-11] év). Vizsgáltuk a jelenség időbeli megjelenését, az emelkedés mértékét, gyakoriságát és az antitest típusát. Leíró statisztikai módszereket és khi-négyzet-próbát alkalmaztunk. Eredmények: A vizsgált populációban a coeliakia gyakorisága 12,52%. Átmeneti antitranszglutamináztiter-emelkedést 48 gyermeknél (10,9%) észleltünk. Összesen 71-szer mértünk átmeneti antitranszglutamináz-emelkedést. A gyermekek közül 34 esetben (70,83%) egyszer fordult elő emelkedést mutató antitest, a többi betegnél 2-8 alkalommal. Gyakrabban tapasztaltunk izolált IgA-típusú emelkedést, mint izolált IgG-típusút (54 vs. 5). Következtetés: Az átmeneti antitranszglutamináz-emelkedés gyakorisága magas, összevethető a valódi coeliakiás csoporttal. Kutatásunk alátámasztja a nemzetközi ajánlást, miszerint mérsékelt mértékű antitranszglutamináz-emelkedés esetén, tünetmentes 1-es típusú diabetesszel gondozott betegben a gluténfogyasztás folytatása és az antitestszintek gyakori kontrollja javasolt.

SUMMARY

INTRODUCTION

The frequent association of type 1 diabetes mellitus with coeliac disease is well known. Development of transitional elevation of anti-tissue transglutaminase antibodies in the diagnosis of type 1 diabetes is reported in some studies. In these cases, the anti-tissue transglutaminase antibodies returned to normal without gluten-free diet.

OBJECTIVE

Our aim was to assess the frequency of transitional elevation of anti-tissue transglutaminase in our type 1 diabetes patients. We aimed to investigate the prevalence of coeliac disease in patients with type 1 diabetes.

METHOD

Patients with type 1 diabetes at the Ist Department of Paediatrics, Semmelweis University, were enrolled in the study (238 girls, 265 boys; the median age at the time of type 1 diabetes diagnosis was 7.83 [4.67-11] years). Descriptive statistical analysis was done and the time of appearance, extent, frequency and type of elevated anti-tissue transglutaminase antibodies were examined.

RESULTS

The proportion of children with diagnosed coeliac disease was 12.52%. We detected transitional anti-tissue transglutaminase elevation in 48 cases (10.9%). Temporarily elevated antibody levels were measured 71 times. In 34 children (70.83%), the temporary elevation occured once, while in the others, antibody levels became positive 2-8 times. The elevation of the IgA antibody was more frequent than the elevation of the IgG antibody (54 vs. 5).

CONCLUSION

The frequency of temporary elevated anti-tissue transglutaminase levels is considered high. Our study confirms the recommendation that in the case of moderate anti-tissue transglutaminase levels with lack of clinical symptoms, control antibody measurement is necessary with ongoing gluten consumption.

Digital module of a complex school-based health education program tries to maintain equality

Issue

Health education of adolescents requires digital communication channels besides the traditional interpersonal setting. Use of e-learnings can be beneficial in multiple aspects when targeting positive health behavior change.

Description

A complex, school-based health education program is operated by Semmelweis University in a North-Hungarian town, Balassagyarmat, given, that the vast majority of students have proper internet access. Ongoing peer education is completed by e-learning modules in order to improve the continuity of the program, repeat key statements, deliver more information and create a private channel to discuss intimate issues. The online system was built on novel educational techniques in gamification and rewarding to enhance motivation and engagement of participants. The same e-learning modules are available for all students from different type of education and sociocultural background. We try to assess if this concept provides equality.

Results

41 multimedia e-learning modules consisting of 12 types of interactive game-like activities has been developed in 10 topics. Each of them are used by around 60-70% of the participants of the program (about 240 students per year). High school students showed slight difference from vocational school students in activity and in performance. According to their feedback, pupils welcome this channel regardless to their type of education.

Lessons

While developing the digital health education program based on new pedagogical methods, the concept was not modified for students of different school types, but all of them participated in the same educational and rewarding system. We believe, that the project trends to maintain equality.

Key messages

Multimedia digital modules are favorable in health education for adolescents. Health education statements can be the same for students of different educational settings.

Potentials of a school-based health education program – a theory based analysis of a good practice

Background

The gap between our knowledge about healthy lifestyle and health behaviours is significant especially in regions with lower socioeconomic conditions. Promoting lifestyle change requires multilevel approach as described by the Capability, Opportunity, Motivation - Behaviour (COM-B) model and school-based interventions can combat inequalities. Our innovative school-based health program in Northern Hungary might serve as an example for future initiatives.

Objectives

Our objective was to develop a sustainable one-year health education program in all five secondary schools of the town of Balassagyarmat including broad spectrum of health related topics. We attempted to find new methods so our classroom setting intervention can target the most factors of COM-B with the integration of best practices and novel tools from the field of education and prior health promotion programs.

Results

It seems possible to integrate elements influencing all levels of COM-B, but in different extent. C: besides knowledge transfer we also focus on improving health-literacy by small-group based, interactive and experiential education enhanced with gamification and an e-learning module. We believe that adolescents have the physical ability for a healthy lifestyle. O: by targeting all students from each class we shape social norms, nevertheless realizable changes in the physical environment is limited. M: both reflective and automatic mechanisms are reinforced by 30-day challenges and rewarding managed by a shared online educational platform ensuring continuality and peer-educators who serve as role-models. The involvement of earlier participants as educators assures the sustainability of the program as well as the internalization of its main messages.

Conclusions

Well-designed school-based health education programs may aspire for multilevel effect in promoting healthy behaviours even between the restricted opportunities of classroom settings with weakest potential in environmental change.

Key messages

Health education in classroom setting might shape social norms, and motivation. Targeting change in physical environment is challenging in school-based health programs.
