The COVID-19 pandemic dramatically reduced admissions of children with and without chronic conditions to general paediatric wards

Clinical and immunological characteristics of children diagnosed with-Type 1 diabetes during the COVID-19 pandemic

AIMS

To find clinical and immunological signatures of the SARS-CoV-2 and the COVID-19 pandemic on children newly diagnosed with type 1 diabetes (T1D).

METHODS

A single-centre, retrospective, observational study comparing the clinical and immunological characteristics of children diagnosed with T1D the year before and during the first 2 years of the COVID-19 pandemic. Data extracted from the medical records included clinical and demographic parameters, COVID-19 PCR results and the presence of anti-islet, thyroid and celiac-related antibodies. Also obtained from the medical records was a family history of T1D, celiac disease and autoimmune thyroid disease in a first-degree family member.

RESULTS

A total of 376 children were diagnosed with T1D during the study period. A total of 132 in the pre-COVID era and 246 in the first 2 years of the pandemic. At diagnosis, the pH in children with DKA was lower, and HbA1c tended to be higher in the COVID-19 group compared to the pre-COVID-19 group (7.30 [7.18, 7.35] vs 7.33 [7.19, 7.36], p = 0.046) and (110.9 [86.9, 129.5] vs 100 [80.3, 129.5], p = 0.067]) respectively. Multiple islet antibodies (IA) were significantly more common among patients in the pre-COVID-19 group compared to the COVID-19 group (72% vs 61%, p = 0.032). Tissue transglutaminase antibodies were more common among children diagnosed in the COVID-19 compared to the pre-COVID group (16.6% vs 7.9%, p = 0.022).

CONCLUSIONS

Our findings suggest that SARS-CoV-2 and the environmental alterations caused by the pandemic affected the clinical characteristics and the immunological profile of children diagnosed with T1D. It is, therefore, plausible that the virus plays a role in the autoimmune process causing T1D.

Non-COVID-19 hospitalization and mortality during the COVID-19 pandemic in Iran: a longitudinal assessment of 41 million people in 2019-2022

BACKGROUND

During a COVID-19 pandemic, it is imperative to investigate the outcomes of all non-COVID-19 diseases. This study determines hospital admissions and mortality rates related to non-COVID-19 diseases during the COVID-19 pandemic among 41 million Iranians.

METHOD

This nationwide retrospective study used data from the Iran Health Insurance Organization. From September 23, 2019, to Feb 19, 2022, there were four study periods: pre-pandemic (Sept 23-Feb 19, 2020), first peak (Mar 20-Apr 19, 2020), first year (Feb 20, 2020-Feb 18, 2021), and the second year (Feb 19, 2021-Feb 19, 2022) following the pandemic. Cause-specific hospital admission and in-hospital mortality are the main outcomes analyzed based on age and sex. Negative binomial regression was used to estimate the monthly adjusted Incidence Rate Ratio (IRR) to compare hospital admission rates in aggregated data. A logistic regression was used to estimate the monthly adjusted in-hospital mortality Odds Ratio (OR) for different pandemic periods.

RESULTS

During the study there were 6,522,114 non-COVID-19 hospital admissions and 139,679 deaths. Prior to the COVID-19 outbreak, the standardized hospital admission rate per million person-month was 7115.19, which decreased to 2856.35 during the first peak (IRR 0.40, [0.25-0.64]). In-hospital mortality also increased from 20.20 to 31.99 (OR 2.05, [1.97-2.13]). All age and sex groups had decreased admission rates, except for females at productive ages. Two years after the COVID-19 outbreak, the non-COVID-19 hospital admission rate (IRR 1.25, [1.13-1.40]) and mortality rate (OR 1.05, [1.04-1.07]) increased compared to the rates before the pandemic. The respiratory disease admission rate decreased in the first (IRR 0.23, [0.17-0.31]) and second years (IRR 0.35, [0.26-0.47] compared to the rate before the pandemic. There was a significant reduction in hospitalizations for pneumonia (IRR 0.30, [0.21-0.42]), influenza (IRR 0.04, [0.03-0.06]) and COPD (IRR 0.39, [0.23-0.65]) during the second year. There was a significant and continuous rise in the hematological admission rate during the study, reaching 186.99 per million person-month in the second year, reflecting an IRR of 2.84 [2.42-3.33] compared to the pre-pandemic period. The mortality rates of mental disorders (OR 2.15, [1.65-2.78]) and musculoskeletal (OR 1.48, [1.20-1.82), nervous system (OR 1.42, [1.26-1.60]), metabolic (OR 1.99, [1.80-2.19]) and circulatory diseases (OR 1.35, [1.31-1.39]) increased in the second year compare to pre-pandemic. Myocardial infarction (OR 1.33, [1.19-1.49]), heart failure (OR 1.59, [1.35-1.87]) and stroke (OR 1.35, [1.24-1.47]) showed an increase in mortality rates without changes in hospitalization.

CONCLUSIONS

In the era of COVID-19, the changes seem to have had a long-term effect on non-COVID-19 diseases. Countries should prepare for similar crises in the future to ensure medical services are not suspended.

COVID-19 in Western Australia: 'The last straw' and hopes for a 'new normal' for parents of children with long-term conditions

BACKGROUND

Children with long-term conditions are vulnerable due to the treatments required for their conditions. Since the start of the coronavirus disease 2019 (COVID-19) pandemic, Western Australians experienced restrictions that changed daily life activities but were able to return to some of their previous routines due to the restrictions.

AIM

The study explored the stress experiences of parents caring for children with long-term conditions during COVID-19 in Western Australia.

DESIGN AND PARTICIPANTS

The study was codesigned with a parent representative caring for children with long-term conditions to ensure essential questions were targeted. Twelve parents of children with various long-term conditions were recruited. Ten parents completed the qualitative proforma, and two parents were interviewed in November 2020. Interviews were audio-recorded and transcribed verbatim. Data were anonymised and analysed using reflexive thematic analysis.

FINDINGS

Two themes were produced: (1) 'Keep my child safe' describes the children's vulnerabilities due to their long-term conditions, the adjustments parents' made to keep their children safe and the various consequences faced. (2) 'COVID-19's silver lining' covers the positives of the COVID-19 pandemic, including their children having fewer infections, the availability of telehealth appointments, relationship improvements and the parent's hopes for a new normal where behaviours prevent transmission of infectious (e.g., hand sanitising).

CONCLUSION

Western Australia provided a unique context for the COVID-19 pandemic due to no transmission of the virus severe acute respiratory syndrome coronavirus 2 at the time of the study. The tend and befriend theory aids in explaining the parents' stress experiences, and the application highlights a unique aspect of this theory. Parents tended to their children during COVID-19, but many could no longer rely on others for connection, support and respite, and became further isolated in attempting to protect their children due to COVID-19 consequences. The findings highlight that some parents of children with long-term conditions need specific attention during times of pandemics. Further review is recommended to support parents through the impact of COVID-19 and similar crises.

PATIENT OR PUBLIC CONTRIBUTION

This study was codesigned with an experienced parent representative who was part of the research team and involved throughout the research process to ensure meaningful end-user engagement and ensure essential questions and priorities were addressed.

How did the COVID-19 pandemic affect inpatient care for children in Germany? An exploratory analysis based on national hospital discharge data

BACKGROUND

The delivery of health services around the world faced considerable disruptions during the COVID-19 pandemic. While this has been discussed for a number of conditions in the adult population, related patterns have been studied less for children. In light of the detrimental effects of the pandemic, particularly for children and young people under the age of 18, it is pivotal to explore this issue further.

METHODS

Based on complete national hospital discharge data available via the German National Institute for the Reimbursement of Hospitals (InEK) data browser, we compare the top 30 diagnoses for which children were hospitalised in 2019, 2020, 2021 and 2022. We analyse the development of monthly admissions between January 2019 and December 2022 for three tracers of variable time-sensitivity: acute lymphoblastic leukaemia (ALL), appendicitis/appendectomy and tonsillectomy/adenoidectomy.

RESULTS

Compared to 2019, total admissions were approximately 20% lower in 2020 and 2021, and 13% lower in 2022. The composition of the most frequent principal diagnoses remained similar across years, although changes in rank were observed. Decreases were observed in 2020 for respiratory and gastrointestinal infections, with cases increasing again in 2021. The number of ALL admissions showed an upward trend and a periodicity prima vista unrelated to pandemic factors. Appendicitis admissions decreased by about 9% in 2020 and a further 8% in 2021 and 4% in 2022, while tonsillectomies/adenoidectomies decreased by more than 40% in 2020 and a further 32% in 2021 before increasing in 2022; for these tracers, monthly changes are in line with pandemic waves.

CONCLUSIONS

Hospital care for critical and urgent conditions among patients under the age of 18 was largely upheld in Germany during the COVID-19 pandemic, potentially at the expense of elective treatments. There is an alignment between observed variations in hospitalisations and pandemic mitigation measures, possibly also reflecting changes in demand. This study highlights the need for comprehensive, intersectoral data that would be necessary to better understand changing demand, unmet need/foregone care and shifts from inpatient to outpatient care, as well as their link to patient outcomes and health care efficiency.

The impact of the first peak of the COVID-19 pandemic on childhood myopia control practice patterns among ophthalmologists-an international pediatric ophthalmology and strabismus council global perspective

BACKGROUND

The prevalence of myopia keeps increasing during the COVID-19 pandemic. We aimed to map the worldwide treatment preferences of ophthalmologists managing myopia control during the first wave of the pandemic.

METHODS

An online questionnaire inquiring about pharmacological and optical treatment patterns during the first half of 2020 was sent to pediatric ophthalmology as well as general ophthalmology memberships worldwide. The results among pediatric ophthalmologists were compared to a previous study we performed before the pandemic.

RESULTS

A total of 2269 respondents from 94 countries were included. Most respondents were pediatric ophthalmologists (64.6%), followed by ophthalmologists from other subspecialties (32.3%). The preferred modality for all geographical regions was a combination therapy of pharmacological and optical treatments. When evaluated independently, the pharmacological treatment was more popular than the optical treatment in most regions other than East Asia (P < 0.001). Compared to a pre-pandemic questionnaire, the participation of pediatric ophthalmologists affiliated with non-university hospitals increased. Additionally, the prevalence of respondents utilizing either any type of pharmacological treatment and those that using only evidence-based treatments increased globally. Although a decline in the use of optical treatment was evident worldwide, the use of evidence-based optical treatments increased.

CONCLUSION

Ophthalmologists around the world preferred a combination therapy of pharmacological and optical treatments. More pediatric ophthalmologists treated myopia progression and preferred a better evidence-based approach to control myopia. These trends reflect a positive response and more awareness of the rising prevalence of myopia due to the increased burden of myopia imposed by the COVID-19 pandemic.

The Impact of COVID-19 Pandemic on Patient Admissions to the Developmental Pediatrics Unit: An Outpatient Clinic in Eastern Turkey

OBJECTIVE

The aim of this study was to analyze the impact of coronavirus disease 2019 pandemic on the number and diagnosis of patients admitted to the Developmental Pediatrics Unit. Materilas and Methods: We compared the number and the diagnosis of patients admitted to the Developmental Pediatrics Unit by using International Classification of Diseases and Related Health Problems 10th revision (ICD-10) codes of our institution's electronic health data before and after 18 months from March 16 2020, when coronavirus disease 2019 pandemic was declared in Turkey. Statistical analyses were performed by using International Business Machines Statistical Package for Social Sciences for windows version 22.0 (Armonk, NY) program.

RESULTS

We found that the number of patients admitted to the Developmental Pediatrics Unit decreased during the pandemic period (pre-coronavirus disease 2019 n = 1107, during coronavirus disease 2019 n = 761). There was no significant difference between the ratio of the most common diagnosis (prematurity) before and during the pandemic period (32% and 30.6% respectively). It was observed that the ratio of children with speech delay (17.4%-23%, P = .003) increased during the pandemic, while there was a significant decrease in the ratio of admissions with Down syndrome (11.6%-6.6%, P < .001).

CONCLUSION

We found that the number of admissions to the Developmental Pediatrics Unit with developmental difficulties decreased significantly during the pandemic. The ratio of admissions of speech delay increased during the same period, while admissions with Down syndrome decreased. This increase may be due to lockdown, increase in electronic screen exposure, and lack of stimuli and the decrease may be due to the risk of severe illness from coronavirus disease 2019. The decrease in admissions of patients who require developmental follow-up reveals the need for additional efforts such as implementing tele-health to our daily practice.

[Influence of the COVID-19 pandemic on the occurrence of neurological infectious diseases]

BACKGROUND

During the coronavirus disease 2019 (COVID-19) pandemic a wide range of hygiene measures were implemented to contain the spread of infections with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Besides a mitigation of SARS-CoV‑2, a decline in the number of other respiratory tract infections could be observed. Interestingly, the numbers for some infections of the central nervous system (CNS) decreased as well.

OBJECTIVE

This review article shows the development of important CNS infections in Germany during the COVID-19 pandemic.

MATERIAL AND METHOD

This article is based on relevant literature on the epidemiology of CNS infections during the COVID-19 pandemic up to autumn 2022.

RESULTS

During the COVID-19 pandemic the frequency of bacterial meningitis caused by Streptococcus pneumoniae, Neisseria meningitidis and Haemophilus influenzae significantly declined. The frequency of viral meningitis, particularly those caused by Enterovirus, decreased as well. In contrast, the number of patients suffering from tick-borne encephalitis significantly increased within the first year of the pandemic.

DISCUSSION

During the pandemic there was a decrease in cases of bacterial and viral meningitis, most likely due to the general containment strategies and social contact restrictions. The increase of infections transmitted by ticks could be a consequence of changed leisure activities during the pandemic.

Trends in Pediatric Acute Otitis Media Burden During the First COVID-19 Year

OBJECTIVE

To study the changes in acute otitis media (AOM) pediatric emergency department (PED) visits and pediatric admission before and during the first coronavirus disease 2019 (COVID-19) year.

STUDY DESIGN

Retrospective case review.

SETTING

Secondary care center.

PATIENTS

Children younger than 18 years with all-cause and AOM-related PED visits and pediatric admissions for 3 years (March 1, 2018-January 28, 2021) were identified. Children were categorized according to age (0-2, 2-6, and 6-18 yr) and their date of presentation: pre-COVID-19 (yearly average of visits/admissions during the 2 prepandemic years: March 1, 2018-February 28, 2019 and March 1, 2019-February 29, 2020) or COVID-19 year (visits/admissions between March 1, 2020-February 28, 2021).

INTERVENTION

Pre- and post-COVID-19 emergence, alternating lockdowns, kindergarten and school closures, and increased hygiene measures.

MAIN OUTCOME MEASURE

Post- versus pre-COVID-19 AOM PED visit and pediatric admission incidence rate ratios (IRRs), using a generalized estimating equation model with a negative binomial regression calculation, while controlling for monthly fluctuations.

RESULTS

Annual AOM visits/admissions during the pre-COVID-19 and COVID-19 years were 517 and 192 and 256 and 94, respectively (p < 0.05 for both). For children aged 0 to 2 years, AOM visits/admissions significantly decreased during the first COVID-19 year, compared with the pre-COVID years (β = -1.11 [IRR, 0.33; 95% confidence interval [CI], 0.26-0.42; p < 0.005] and β = -1.12 [IRR, 0.33; 95% CI, 0.25-0.42; p < 0.005]). Relatively to all-cause of children aged 0 to 2 years, AOM visits/admissions decreased during the first COVID-19 year versus the pre-COVID-19 years (β = -2.14 [IRR, 0.12; 95% CI, 0.08-0.17; p < 0.005] and β = -1.36 [IRR, 0.26; 95% CI, 0.23-0.29; p < 0.005]) and had monthly fluctuations coinciding with the lockdown/relaxation measures. For children aged 2 to 6 years, the reduction in AOM admissions was significant (β = -1.70, IRR, 0.18; 95% CI, 0.09-0.37; p < 0.005). No significant differences were observed for children aged 6 to 18 years because of the small sample size.

CONCLUSION

Pediatric AOM burden substantially decreased during the first COVID-19 year.

Impact of the COVID-19 Outbreak on Disease Spectrum of Pediatric Intensive Care Units

Purpose

We aimed to analyze the changes in the disease spectrum data of a pediatric intensive care unit (PICU) in Nanjing, China, during the COVID-19 outbreak and explore a feasible plan for the treatment of critically ill children.

Methods

This retrospective study used data from our PICU from 1 January 2018 to 31 December 2020. Patient demographics, distribution of disease spectrum, results of etiological examinations, and the PICU length of stay (LOS) were compared during the COVID-19 period (2020) and the previous years (2018 and 2019).

Results

In 2020, the number of PICU admissions was 46.8 and 47.8% lower than that in 2018 and 2019, respectively. There were significant differences in the number of patients in PICU among different age groups, and these differences were mainly found in children aged <4 years and older than 14 years. The percentage of the number of patients in PICU with respiratory diseases decreased significantly, while those with hematological diseases, poisoning, and rare diseases increased significantly. Moreover, the number of patients with rare diseases increased significantly, while the number of patients with mitochondrial diseases exceeded that of those with autoimmune encephalitis. The PICU LOS in 2020 was higher than that observed in 2018 and 2019, indicating that the changes in the PICU disease spectrum did not directly affect the PICU LOS. Etiological examinations revealed that during the COVID-19 period, the number of patients in PICU with bacterial infections increased, and those with viral infections decreased, although not statistically significant.

Conclusions

A striking decrease in the number of PICU admissions was observed during the COVID-19 outbreak, which caused a significant change in the PICU disease spectrum. Changes in the number and characteristics of patients admitted to PICUs should be considered for facilitating the effective working of PICUs during the COVID-19 pandemic.

Impact of COVID-19 on Admissions and Outcomes for Children With Complex Chronic Conditions

BACKGROUND

Although pediatric health care use declined during the coronavirus disease 2019 (COVID-19) pandemic, the impact on children with complex chronic conditions (CCCs) has not been well reported.

OBJECTIVE

To describe the impact of the pandemic on inpatient use and outcomes for children with CCCs.

METHODS

This multicenter cross-sectional study used data from the Pediatric Health Information System. We examined trends in admissions between January 2020 through March 2021, comparing them to the same timeframe in the previous 3 years (pre-COVID-19). We used generalized linear mixed models to examine the association of the COVID-19 period and outcomes for children with CCCs presenting between March 16, 2020 to March 15, 2021 (COVID-19 period) to the same timeframe in the previous 3 years (pre-COVID-19).

RESULTS

Children with CCCs experienced a 19.5% overall decline in admissions during the COVID-19 pandemic. Declines began in the second week of March of 2020, reaching a nadir in early April 2020. Changes in admissions varied over time and by admission indication. Children with CCCs hospitalized for pneumonia and bronchiolitis experienced overall declines in admissions of 49.7% to 57.7%, whereas children with CCCs hospitalized for diabetes experienced overall increases in admissions of 21.2%. Total and index length of stay, costs, and ICU use, although statistically higher during the COVID-19 period, were similar overall to the pre-COVID-19 period.

CONCLUSIONS

Total admissions for children with CCCs declined nearly 20% during the pandemic. Among prevalent conditions, the greatest declines were observed for children with CCCs hospitalized with respiratory illnesses. Despite declines in admissions, overall hospital-level outcomes remained similar.

Decline in the number of patients with meningitis in German hospitals during the COVID-19 pandemic

Background and objectives

In 2020, a wide range of hygiene measures was implemented to mitigate infections caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). In consequence, pulmonary infections due to other respiratory pathogens also decreased. Here, we evaluated the number of bacterial and viral meningitis and encephalitis cases during the coronavirus disease 2019 (COVID-19) pandemic.

Methods

In a multicentre retrospective analysis of data from January 2016 until December 2020, numbers of patients diagnosed with bacterial meningitis and other types of CNS infections (such as viral meningitis and encephalitis) at 26 German hospitals were studied. Furthermore, the number of common meningitis-preceding ear-nose-throat infections (sinusitis, mastoiditis and otitis media) was evaluated.

Results

Compared to the previous years, the total number of patients diagnosed with pneumococcal meningitis was reduced (n = 64 patients/year in 2020 vs. n = 87 to 120 patients/year between 2016 and 2019, all p < 0.05). Additionally, the total number of patients diagnosed with otolaryngological infections was significantly lower (n = 1181 patients/year in 2020 vs. n = 1525 to 1754 patients/year between 2016 and 2019, all p < 0.001). We also observed a decline in viral meningitis and especially enterovirus meningitis (n = 25 patients/year in 2020 vs. n = 97 to 181 patients/year between 2016 and 2019, all p < 0.001).

Discussion

This multicentre retrospective analysis demonstrates a decline in the number of patients treated for viral and pneumococcal meningitis as well as otolaryngological infections in 2020 compared to previous years. Since the latter often precedes pneumococcal meningitis, this may point to the significance of the direct spread of pneumococci from an otolaryngological focus such as mastoiditis to the brain as one important pathophysiological route in the development of pneumococcal meningitis.

COVID-19 and vaccination induced changes in hospital activity in Malta, Q1 2020 to Q1 2021: a population-based study

Background

COVID-19 has severely impacted global healthcare services. Malta has only one acute state hospital, Mater Dei Hospital (MDH), and at the time of writing is the most vaccinated country in Europe. Malta thus provides an ideal setting to assess the impact of COVID-19 on healthcare services at population level, including the impact of vaccination on hospital admissions.

Methods

Hospital data was obtained as anonymised totals from MDH’s Clinical Performance Unit and the European Centre for Disease Prevention and Control. COVID-19-related data was obtained from the Ministry of Health dashboard. Comparative assessments were performed to explore associations between the COVID-19 situation, vaccination, and hospital activity. Poisson regression was used to model the counts of monthly accident and emergency (A&E), outpatient clinics attendances and hospital admissions.

Results

A&E, hospital admissions, and outpatient clinics attendances declined (31.88%; 23.89%; 29.57%; p < 0.01 respectively) with onset of COVID-19 till April 2021 when compared to pre-COVID years (2017–2019). Admissions due to COVID-19 initially increased in parallel to the population’s COVID positivity. Vaccination rollout led to a decline in COVID-19 admissions.

Conclusions

The drastic drop in admissions and outpatient attendees was expected but not for A&E attendees as acutely ill patients should still have attended. This is of public health concern since delayed or deferred medical management increases population morbidity, mortality and increases the eventual burden on the healthcare system. Mass vaccination saw the return to normality with an increase in A&E burden.

The effect of COVID-19 pandemic on hospitalizations and disease characteristics of adolescents with anorexia nervosa

Social distancing and quarantines have major negative psychological implications. Our aim was to study the rate of pediatric hospitalizations due to anorexia nervosa (AN) during the first year of coronavirus disease 2019 (COVID-19) pandemic as compared to previous years, with regard to clinical and laboratory parameters. This is a retrospective study in a tertiary pediatric hospital in Israel. Data regarding inpatient hospitalizations due to AN were retrieved, then epidemiological, clinical, and laboratory parameters compared. During the entire study period, 275 hospitalizations were due to AN: 94 patients were admitted during the 12 months of the pandemic as compared to a yearly mean of 45.25 during 2015-2019, resulting in a 2.4-fold increase (p < 0.001). The mean admission age and female predominance were similar in the two study groups. The weight of the patients at admission was higher during the COVID-19 period (44.5 kg vs. 41.2 kg, p = 0.004), and fewer patients had clinical signs typical of AN upon physical examination (p = 0.022). There was a 35% reduction in median hospitalization duration (9 days [IQR 8.21] in 2020-2021 and 14 [IQR 6, 16.75] days in 2015-2019, p = 0.01). No other differences were found.

CONCLUSIONS

During the first year of the COVID-19 pandemic, there was a significant increase in the number of adolescents hospitalized with AN. Nevertheless, disease characteristics were not more severe as compared to the preceding 5 years.

WHAT IS KNOWN

• Social distancing and quarantines were announced during the COVID-19 pandemic in numerous countries. These measures have potential negative psychological effects on adolescents.

WHAT IS NEW

• During the COVID-19 pandemic period, there was an increase in the number of hospitalizations of adolescents with AN, although disease characteristics were not more severe as compared to the preceding 5 years.

Chronic respiratory diseases other than asthma in children: the COVID-19 tsunami

Coronavirus disease 2019 (COVID-19) affects all components of the respiratory system, including the neuromuscular breathing apparatus, conducting and respiratory airways, pulmonary vascular endothelium, and pulmonary blood flow. In contrast to other respiratory viruses, children have less severe symptoms when infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). A minority of children experience a post-infectious inflammatory syndrome, the pathology and long-term outcomes of which are poorly understood. The reason for the lower burden of symptomatic disease in children is not yet clear, but several pathophysiological characteristics are postulated. The SARS-CoV-2 pandemic has brought distinct challenges to the care of children globally. Proper recommendations have been proposed for a range of non-asthmatic respiratory disorders in children, including primary ciliary dyskinesia and cystic fibrosis. These recommendations involve the continuation of the treatment during this period and ways to maintain stability. School closures, loss of follow-up visit attendance, and loss of other protective systems for children are the indirect outcomes of measures to mitigate the COVID-19 pandemic. Moreover, COVID-19 has reshaped the delivery of respiratory care in children, with non-urgent and elective procedures being postponed, and distancing imperatives have led to rapid scaling of telemedicine. The pandemic has seen an unprecedented reorientation in clinical trial research towards COVID-19 and a disruption in other trials worldwide, which will have long-lasting effects on medical science. In this narrative review, we sought to outline the most recent findings on the direct and indirect effects of SARS-CoV-2 pandemic on pediatric respiratory chronic diseases other than asthma, by critically revising the most recent literature on the subject.

[Consequences of COVID-19 pandemic over acute bronchiolitis hospitalizations in the center and east of Spain]

INTRODUCTION

Non-pharmaceutical interventions that have been implemented in southern hemisphere countries because of COVID-19 pandemic declaration in March 2020, have evidenced some unexpected changes in the way of spreading of many other viruses. This study as a part of ECEALHBA's Project, reports the consequences of COVID-19 pandemic over 2020-2021 bronchiolitis epidemic period in the Central and Eastern regions of Spain.

METHOD

Multicenter, observational, descriptive and ambispective study of admitted infants with the diagnosis of bronchiolitis in 16 Spanish hospitals involved in the investigation project. Five epidemic periods previous to COVID-19 pandemic, from 2015 to 2020, were compared with the current one, 2020-2021, in both a qualitative and quantitative manner.

RESULTS

Total of 4643 infants were admitted to the participating hospitals along the study period. Pandemic season hospital admissions for bronchiolitis were 94.1% lower than in pre-pandemic period. December and January were peak months for bronchiolitis admissions during pre-pandemic period, but September was the peak month during pandemic year. There was a progressive decrease of admissions from this moment until the end of the follow up, in April 2021. Rhinovirus has been the commonest etiology for bronchiolitis in 2020-2021 epidemic period of bronchiolitis.

CONCLUSIONS

Some of the non-pharmaceutical interventions initiated because of COVID-19 pandemic are probably related to the dramatic decrease of bronchiolitis cases in 2020-2021 season. It would be rewarding to purpose novel research to clarify how these simple interventions can be useful, close to vaccines and antiviral drugs, to achieve the goal of avoiding the spread of respiratory viruses in pediatric population.
