[PMID: 38693043 PMCID: PMC11361882 DOI: 10.1016/j.jped.2024.03.012] [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: 02/11/2024] [Revised: 03/26/2024] [Accepted: 03/27/2024] [Indexed: 05/03/2024] Open
Abstract
OBJECTIVE To compare the effectiveness of inhaled Magnesium Sulfate associated with Salbutamol versus Inhaled Salbutamol alone in patients with moderate and severe asthma exacerbations. METHOD Clinical, prospective and randomized study with patients between 3 and 14 years of age divided into two groups: one to receive inhaled salbutamol associated with magnesium sulfate (GSM), the other to receive inhaled salbutamol alone (GS). The sample consisted of 40 patients, 20 patients in each group. Severity was classified using the modified Wood-Downes score, with values between 4 and 7 classified as moderate and 8 or more classified as severe. RESULTS Post-inhalation scores decreased both in patients who received salbutamol and magnesium and in those who received salbutamol alone, with no statistically significant difference between the groups. CONCLUSIONS Despite the benefits when administered intravenously, inhalation of the drug alone or in combination did not reduce the severity of the exacerbation.

Abstract
OBJECTIVE Evaluate a nurse-initiated quality improvement (QI) intervention aimed at enhancing asthma treatment in a pediatric emergency department (ED), utilizing outcomes and workflow. METHODS We evaluated the impact of QI interventions for pediatric patients presenting to the ED with asthma with pre-post analysis. A pediatric asthma score (PAS) of >8 indicated moderate to severe asthma. This secondary analysis of the electronic health record (EHR), evaluated on 1) patient outcomes (time to clinical treatment, ED length of stay [EDLOS], admissions and discharges home), 2) clinical workflow. RESULTS We compared 886 visits occurring between 01/01/2015 and 09/27/2015 (pre-implementation period) with 752 visits between 01/01/2016 and 09/27/2016 (post-implementation). Time to first documentation of PAS was decreased post-intervention (p<.001) by >30 min (75 ± 57 to 39 ± 54 min). There were significant decreases in time to treatment with both steroid and bronchodilator administration (both p<.001). EDLOS did not significantly change. Based on acuity level, those discharged home from the ED with high acuity (PAS score ≥8), had a significant decrease in time to initial PAS, steroid and bronchodilator use and EDLOS. Of those with high acuity who were admitted to the hospital, there was a difference pre- to post-implementation, in time to first PAS (p<.05), but not to treatment. Workflow visualization provided additional insights and detailed (task level) comparisons of the timing of ED activities. CONCLUSIONS Nurse-initiated ED interventions, can significantly improve the timeliness of pediatric asthma evaluation and treatment. Examining workflow along with the outcomes, can better inform QI evaluations and clinical management.

Abstract
OBJECTIVE This study aimed to compare statewide emergency medical services protocols for the management of pediatric respiratory distress. METHODS We performed a descriptive study of emergency medical services protocols for the management of pediatric respiratory distress in the United States, excluding those without model or mandatory protocols. We compared medication recommendations for specific disease processes, including asthma, croup, epiglottitis, anaphylaxis, generalized respiratory distress, intubation, and drug assisted intubation. RESULTS Thirty-four state protocols were included. All had protocols to address the management of pediatric respiratory distress. There was high agreement in albuterol use for bronchospasm and epinephrine use in anaphylaxis. Epinephrine was recommended in all anaphylaxis protocols, 27 croup protocols (79%), and 3 epiglottitis protocols (9%). Six states (18%) called for albuterol in patients with generalized respiratory distress. Steroid recommendations and indications had variance among states; 26 states (76%) allowed steroid use in patients with asthma, 19 states (56%) recommended steroid use in anaphylaxis, and 11 (32%) recommended steroid use in croup protocols. The route for steroid administration also varied among protocols. Five states (15%) allowed continuous positive airway pressure application in pediatric patients, whereas endotracheal intubation and rapid sequence intubations had varying requirements as well as recommendations for use. Twelve (35%) listed impending or current respiratory failure as an indication, whereas other states had specific markers, such as Glasgow Coma Scale or oxygen saturation, as indications. CONCLUSIONS All included states had specific recommendations for the management of pediatric respiratory distress. There was consistency in recommendations for albuterol use for wheezing and epinephrine use for anaphylaxis. However, there was wide variability in other uses for epinephrine, steroid administration, continuous positive airway pressure use, and specific treatments for croup and epiglottitis. The findings of this study provide a base for important future evidence-based protocol developments and changes in prehospital pediatric respiratory distress treatment.

Abstract
BACKGROUND Asthma is a leading cause of pediatric hospitalization in the United States. Children hospitalized with asthma are often managed in different care settings during hospitalization, posing challenges to accurate communication among care providers about illness severity. Our objective was to study the feasibility, reliability, and safety of a new pediatric hospital-wide asthma severity score (HASS) across different care units within a single tertiary-care pediatric center. METHODS 150 patients between the ages of 2 and 18 years hospitalized with a principal diagnosis of status asthmaticus were included in this study. Study patients were followed from the time of initial triage in the emergency department until the time of medical readiness for discharge. Rates of medical errors, early transfers to a higher level of care and medically indicated hospital length of stay (LOS) were compared between 75 patients before and 75 patients after widespread implementation of the HASS using retrospective chart review and anonymous staff reporting. Interrater reliability was determined by collecting independent HASS scores from blinded staff members after tandem or simultaneous patient assessment. RESULTS Interrater reliability among untrained staff members using the HASS was high. Hospital LOS, rates of adverse events, medical errors, and early transfer to a higher level of care were not significantly different before and after widespread HASS implementation. CONCLUSION The HASS is a reliable asthma severity tool that can be used throughout hospitalization and among multiple clinical providers to trend clinical progress and optimize communication, particularly during times of care handoffs.

Cerebroventricular Injection of Pgk1 Attenuates MPTP-Induced Neuronal Toxicity in Dopaminergic Cells in Zebrafish Brain in a Glycolysis-Independent Manner. Int J Mol Sci 2022; 23:ijms23084150.

Abstract
Parkinson’s disease (PD) is characterized by the degeneration of dopaminergic neurons. While extracellular Pgk1 (ePgk1) is reported to promote neurite outgrowth, it remains unclear if it can affect the survival of dopaminergic cells. To address this, we employed cerebroventricular microinjection (CVMI) to deliver Pgk1 into the brain of larvae and adult zebrafish treated with methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) as a PD-like model. The number of dopamine-producing cells in ventral diencephalon clusters of Pgk1-injected, MPTP-treated embryos increased over that of MPTP-treated embryos. Swimming distances of Pgk1-injected, MPTP-treated larvae and adult zebrafish were much longer compared to MPTP-treated samples. The effect of injected Pgk1 on both dopamine-producing cells and locomotion was time- and dose-dependent. Indeed, injected Pgk1 could be detected, located on dopamine neurons. When the glycolytic mutant Pgk1, Pgk1-T378P, was injected into the brain of MPTP-treated zebrafish groups, the protective ability of dopaminergic neurons did not differ from that of normal Pgk1. Therefore, ePgk1 is functionally independent from intracellular Pgk1 serving as an energy supplier. Furthermore, when Pgk1 was added to the culture medium for culturing dopamine-like SH-SY5Y cells, it could reduce the ROS pathway and apoptosis caused by the neurotoxin MPP+. These results show that ePgk1 benefits the survival of dopamine-producing cells and decreases neurotoxin damage.

Abstract
OBJECTIVES The aim of this study was to determine the interrater reliability (IRR) of the Pediatric Asthma Score (PAS) and to evaluate the discriminative performance of this score to predict the need for hospital admission among children with acute asthma. METHODS A secondary analysis of prospective data was performed to compare triage nurse and study personnel PAS scores among children aged 6 to 18 years presenting to the emergency department with acute asthma. The IRR was determined by calculation of weighted Cohen κ with differences evaluated by Wilcoxon ranked pairs. Receiver operating characteristic curves were created to evaluate the predictive ability of PAS to determine the need for hospital admission. RESULTS One hundred one subjects were evaluated by both study personnel and a triage nurse with PAS score recorded. The IRR of the total PAS score was determined to be moderate (κ = 0.57) and acceptable, although lower than previously reported. Individual components of the PAS score demonstrated fair to substantial agreement. Receiver operating characteristic analysis demonstrated total PAS at emergency department triage to have poor test characteristics in predicting the need for hospital admission, whether PAS was determined by study personnel, triage nurse, or an average score (area under the curve, 0.62-0.65). CONCLUSIONS In this study, total PAS score demonstrated a moderate and acceptable level of IRR with a poor discriminative ability to determine the need for hospital admission at the time of ED triage.

Abstract
Asthma is the most common disease of childhood globally and acute asthma is the most significant risk factor for asthma-related death and chronic complications. This article will aim to synthesize the most up-to-date research and translate it into a more practical guide to managing acute asthma on a more daily basis. The use of clinical severity score is reviewed alongside the use of history and clinical findings in making objective assessments of patients presenting with acute asthma. Practical evidence-based pathways and a stepwise approach are provided for management of acute asthma in the home, outpatient, emergency, and intensive care settings. In doing so, popular myths are dispelled and practices in relation to management of acute asthma and use of asthma related medications are clarified. Having a standardized approach to management of acute asthma will bring us one step closer to reducing exacerbations and achieving the goal of having zero tolerance towards exacerbations.

Efficacy of a loading dose of IV salbutamol in children with severe acute asthma admitted to a PICU: a randomized controlled trial. Eur J Pediatr 2022; 181:3701-3709. [PMID: 35922522 PMCID: PMC9508206 DOI: 10.1007/s00431-022-04576-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/03/2022] [Revised: 07/18/2022] [Accepted: 07/21/2022] [Indexed: 11/11/2022]
Abstract
UNLABELLED The optimal dose regimen for intravenous (IV) treatment in children with severe acute asthma (SAA) is still a matter of debate. We assessed the efficacy of adding a salbutamol loading dose to continuous infusion with salbutamol in children admitted to a pediatric intensive care unit (PICU) with SAA. This multicentre, placebo-controlled randomized trial in the PICUs of four tertiary care children's hospitals included children (2-18 years) with SAA admitted between 2017 and 2019. Children were randomized to receive either a loading dose IV salbutamol (15 mcg/kg, max. 750 mcg) or normal saline while on continuous salbutamol infusion. The primary outcome was the asthma score (Qureshi) 1 h after the intervention. Analysis of covariance models was used to evaluate sensitivity to change in asthma scores. Serum concentrations of salbutamol were obtained. Fifty-eight children were included (29 in the intervention group). Median baseline asthma score was 12 (IQR 10-13) in the intervention group and 11 (9-12) in the control group (p = 0.032). The asthma score 1 h after the intervention did not differ significantly between the groups (p = 0.508, β-coefficient = 0.283). The median increase in salbutamol plasma levels 10 min after the intervention was 13 μg/L (IQR 5-24) in the intervention group and 4 μg/L (IQR 0-7) in the control group (p = 0.001). Side effects were comparable between both groups. CONCLUSION We found no clinical benefit of adding a loading dose IV salbutamol to continuous infusion of salbutamol, in children admitted to the PICU with SAA. Clinically significant side effects from the loading dose were not encountered. WHAT IS KNOWN • Pediatric asthma guidelines struggle with an evidence-based approach for the treatment of SAA beyond the initial steps of oxygen suppletion, repetitive administration of inhaled β2-agonists, and systemic steroids. • During an SAA episode, effective delivery of inhaled drugs is unpredictable due to severe airway obstruction. WHAT IS NEW • This study found no beneficial effect of an additional loading dose IV salbutamol in children admitted to the PICU. • This study found no clinically significant side effects from the loading dose.

Abstract
OBJECTIVES Little is known about emergency medical services' (EMS') management of pediatric asthma. This study's objective was to describe the demographic, clinical, and geographic characteristics of current EMS' management of pediatric asthma in the state with the fourth-largest pediatric population. METHODS This was a retrospective observational study of EMS patients ages 2 to 18 years with an asthma exacerbation from 2011 to 2016. Patients from Florida's EMS Tracking and Reporting System were included if their EMS chief complaint indicated respiratory distress, if they received at least 1 albuterol treatment, and if they were transported to a hospital. RESULTS A total of 11,226 patients met the inclusion criteria. The median age was 9 years, and 49% were African-American. Geospatial analysis revealed 4 rural counties with disproportionate numbers of African-American patients. In addition to albuterol, 37% of patients received ipratropium bromide and 9% received systemic corticosteroids. Adjusted logistic regression revealed that the strongest predictors of receiving systemic corticosteroids from EMS were intravenous access (odds ratio, 33.4; 95% confidence interval, 24.4-45.6) and intravenous magnesium sulfate administration (odds ratio, 5.0; 95% confidence interval, 3.4-7.3), indicating a more severe presentation. CONCLUSIONS This statewide study demonstrated low rates of EMS administration of ipratropium bromide and systemic corticosteroids, both evidence-based treatments for asthma exacerbations. Targeted EMS education should attempt to increase utilization of both those medications. In addition, the feasibility and efficacy of EMS administration of oral systemic corticosteroids for children should be explored.

Abstract
Pediatric asthma is a heterogeneous and common chronic condition with significant morbidity and burden on the healthcare system. Despite advances in the field, the disease has proven to be increasingly complex to diagnose and management strategies are constantly evolving. Studies from 2020 have advanced the field even further, particularly with regard to new methods of diagnosis and monitoring, treatment of severe asthma, modifiable risk factors like exercise and obesity, aerosol delivery, and viral respiratory infections contributing to the development of asthma. Continued studies are needed to improve our care for children with asthma and we look forward to future advances. This article is part of our 2020 "Year in Review" series, in which we summarize publications in major topic areas, in the context of selected literature from other journals relevant to our discipline.

Abstract
Acute exacerbations cause significant morbidity and mortality in children with asthma worldwide. Although exacerbations can be minor and transient, in some children they are recurrent and significantly adversely impact quality of life. Children with frequent exacerbations account for a disproportionate amount of unscheduled care in nonprimary health facilities. Frequent exacerbators are often prescribed controller medications, but poor adherence is common. Major predictors for asthma exacerbations include genetic, social, comorbid, biological, and environmental factors. Although virus infections are a key trigger for exacerbations, other environmental factors also significantly increase risk. A previous exacerbation is a major risk factor for future exacerbations and thus identifies children to target for prevention of future episodes. In this review, we discuss both modifiable and fixed factors associated with asthma exacerbations, how to assess children for risk, and which pharmacological and nonpharmacological interventions may be of benefit. Finally, we review the current evidence around treatment within the outpatient setting for an emerging exacerbation.

Abstract
BACKGROUND Intravenous salbutamol is used to treat children with refractory status asthmaticus, however insufficient pharmacokinetic data are available to guide initial and subsequent dosing recommendations for its intravenous use. The pharmacologic activity of salbutamol resides predominantly in the (R)-enantiomer, with little or no activity and even concerns of adverse reactions attributed to the (S)-enantiomer. OBJECTIVE Our aim was to develop a population pharmacokinetic model to characterize the pharmacokinetic profile for intravenous salbutamol in children with status asthmaticus admitted to the pediatric intensive care unit (PICU), and to use this model to study the effect of different dosing schemes with and without a loading dose. METHODS From 19 children (median age 4.9 years [range 9 months-15.3 years], median weight 18 kg [range 7.8-70 kg]) treated with continuous intravenous salbutamol at the PICU, plasma samples for R- and S-salbutamol concentrations (111 samples), as well as asthma scores, were collected prospectively at the same time points. Possible adverse reactions and patients' clinical data (age, sex, weight, drug doses, liver and kidney function) were recorded. With these data, a population pharmacokinetic model was developed using NONMEM 7.2. After validation, the model was used for simulations to evaluate the effect of different dosing regimens with or without a loading dose. RESULTS A two-compartment model with separate clearance for R- and S-salbutamol (16.3 L/h and 8.8 L/h, respectively) best described the data. Weight was found to be a significant covariate for clearance and volume of distribution. No other covariates were identified. Simulations showed that a loading dose can result in higher R-salbutamol concentrations in the early phase after the start of infusion therapy, preventing accumulation of S-salbutamol. CONCLUSIONS The pharmacokinetic model of intravenous R- and S-salbutamol described the data well and showed that a loading dose should be considered in children. This model can be used to evaluate the pharmacokinetic-pharmacodynamic relationship of intravenous salbutamol in children, and, as a next step, the effectiveness and tolerability of intravenous salbutamol in children with severe asthma.

Abstract
The Saudi Pediatric Pulmonology Association (SPPA) is a subsidiary of the Saudi Thoracic Society (STS), which consists of a group of Saudi experts with well-respected academic and clinical backgrounds in the fields of asthma and other respiratory diseases. The SPPA Expert Panel realized the need to draw up a clear, simple to understand, and easy to use guidance regarding the application of different aerosol therapies in respiratory diseases in children, due to the high prevalence and high economic burden of these diseases in Saudi Arabia. This statement was developed based on the available literature, new evidence, and experts' practice to come up with such consensuses about the usage of different aerosol therapies for the management of respiratory diseases in children (asthma and nonasthma) in different patient settings, including outpatient, emergency room, intensive care unit, and inpatient settings. For this purpose, SPPA has initiated and formed a national committee which consists of experts from concerned specialties (pediatric pulmonology, pediatric emergency, clinical pharmacology, pediatric respiratory therapy, as well as pediatric and neonatal intensive care). These committee members are from different healthcare sectors in Saudi Arabia (Ministry of Health, Ministry of Defence, Ministry of Education, and private healthcare sector). In addition to that, this committee is representing different regions in Saudi Arabia (Eastern, Central, and Western region). The subject was divided into several topics which were then assigned to at least two experts. The authors searched the literature according to their own strategies without central literature review. To achieve consensus, draft reports and recommendations were reviewed and voted on by the whole panel.

[PMID: 33621253 PMCID: PMC7901745 DOI: 10.1371/journal.pone.0237620] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2020] [Accepted: 02/04/2021] [Indexed: 12/15/2022] Open
Abstract
BACKGROUND A combination of ipratropium bromide (IB) and salbutamol is commonly used to treat asthma in children and adolescents; however, there has been a lack of consistency in its usage in clinical practice. OBJECTIVE To evaluate the efficacy and safety of IB + salbutamol in the treatment of asthma in children and adolescents. METHODS The MEDLINE, Embase, and Cochrane Library as well as other Chinese biomedical databases (including China Biological Medicine Database, Chinese National Knowledge Infrastructure, Chongqing VIP, and Wanfang Chinese language bibliographic database) were systematically searched from the earliest record date to September 2020 for randomized controlled trials in children and adolescents (≤18 years) with asthma who received IB + salbutamol or salbutamol alone. The primary outcomes included hospital admission and adverse events. A random effects model with a 95% confidence interval (CI) was used. Subgroup analysis was performed according to age, severity of asthma, and co-interventions with other asthma controllers. This study was registered with PROSPERO. RESULTS Of the 1061 studies that were identified, 55 met the inclusion criteria and involved 6396 participants. IB + salbutamol significantly reduced the risk of hospital admission compared with salbutamol alone (risk ratio [RR] 0.79; 95% CI 0.66-0.95; p = 0.01; I2 = 40%). Subgroup analysis only showed significant difference in the risk of hospital admission in participants with severe asthma exacerbation (RR 0.73; 95% CI 0.60-0.88; p = 0.0009; I2 = 4%) and moderate-to-severe exacerbation (RR 0.69; 95% CI 0.50-0.96; p = 0.03; I2 = 3%). There were no significant differences in the risk of adverse events between IB + salbutamol group and salbutamol alone group (RR 1.77; 95% CI 0.63-4.98). CONCLUSION IB + salbutamol may be more effective than salbutamol alone for the treatment of asthma in children and adolescents, especially in those with severe and moderate to severe asthma exacerbation. The very low to high quality of evidence indicated that future well-designed double-blind RCTs with large sample are needed for research on evaluating the effectiveness of IB + salbutamol treatment for asthma in children and adolescents.

Abstract
BACKGROUND Care variability for children with severe acute asthma has been well documented in high-income countries, yet data from low- and middle-income regions are lacking. We sought to characterize the magnitude of practice variability in the care of Latin American children to identify opportunities for standardization of care. METHODS A cross-sectional study performed through a retrospective analysis of contemporaneously collected data of children with severe acute asthma admitted to a center contributing to the LARed Network registry between May 2017 and May 2019. Centers were grouped by geographic location: Atlantic (AT), South Pacific (SP), and North Central (NC). RESULTS Among 434 children, most received care in hospitals in the AT group (54% [235/434]), followed by the NC (23% [101/434]) and SP (23% [98/434]) groups. The majority of children in the AT (92% [215/235]) and SP (91% [89/98]) groups received nebulized salbutamol/albuterol, while metered-dose inhalers were preferred in the NC group (72% [73/101]). There was a wide variation in the use of antibiotics: AT (57% [135/235]), SP (48% [47/98]), and NC (14% [14/101]). The same was true for ipratropium bromide: AT (67% [157/235]), SP (90% [88/98]), and NC (17% [17/101]), and aminophylline: AT (57% [135/235]), NC (5% [5/101]), and SP (0% [0/98]). High-flow nasal cannula was the preferred respiratory support modality in the AT (60% [141/235]) and NC (40% [40/101]) groups, while bilevel positive airway pressure (BiPAP) use was more common in the SP group (80% [78/98]). CONCLUSION We identified significant variability in care for severe acute asthma. Our findings will help to inform the design of future studies, quality improvement initiatives, and development of practice guidelines within Latin America.

Abstract
OBJECTIVE To test the effects of inhaled ipratropium on clinical outcomes of critical asthma in the first randomized trial of this adjunctive therapy in critically ill children. DESIGN Pilot, placebo-controlled, double-blinded, and randomized-controlled trial PATIENTS: Thirty children (15 per group) with critical asthma receiving high-intensity albuterol per a standardized pathway utilizing objective assessments to wean patients to less frequent albuterol administration. INTERVENTIONS Subjects were randomized to receive either nebulized ipratropium bromide (500 µg in 0.9% saline per dose) or an equivalent volume of nebulized 0.9% saline every 6 h until the patient was successfully weaned to albuterol doses every 2 h ("q2 albuterol"). MEASUREMENTS AND MAIN RESULTS Demographics, initial clinical severity score, and asthma histories were similar between groups. There was no significant difference in the median duration of high-intensity albuterol between the treatment group (17.5 [10.3-22.1] h) and placebo group (14.6 [12.7-24.5] days; p = .56). Similarly, there was no significant difference in pediatric intensive care unit length of stay (22.6 [21.1-33.6] vs. 21.4 [16.1-35.8] h; p = .74) or hospital length of stay (48.0 [41.8-59.8] vs. 47.3 [37.2-63.1] h; p = .67). In multivariate linear regression adjusting for identified confounders, treatment with ipratropium was not significantly associated with any of the three outcomes. Side effects were rare and occurred with equally between both groups CONCLUSIONS: Adjunctive therapy with ipratropium was not associated with decreased duration of high-intensity albuterol or shortened length of stay when compared to placebo. A larger, multicenter trial is warranted to confirm that ipratropium does not improve clinical outcomes.

Abstract
OBJECTIVES Prehospital protocols vary across local emergency medical service (EMS) agencies in California. We sought to develop evidence-based recommendations for the out-of-hospital evaluation and treatment of pediatric respiratory distress, and we evaluated the protocols for pediatric respiratory distress used by the 33 California local EMS agencies. METHODS Evidence-based recommendations were developed through an extensive literature review of the current evidence regarding out-of-hospital treatment of pediatric patients with respiratory distress. The authors compared the pediatric respiratory distress protocols of each of the 33 California local EMS agencies with the evidence-based recommendations. Our focus was on the treatment of 3 main pediatric respiratory complaints by presentation: stridor (croup), wheezing < 24 months (bronchiolitis), and wheezing > 24 months (asthma). RESULTS Protocols across the 33 California local EMS agencies varied widely. Stridor (croup) had the highest protocol variability of the 3 presentations we evaluated, with no treatment having uniform use among all agencies. Only 3 (9.1%) of the local EMS agencies differentiated wheezing in children < 24 months of age, referencing this as possible bronchiolitis. All local EMS agencies included albuterol and epinephrine (intravenous/intramuscular) in their pediatric wheezing (asthma) treatment protocols. The least common treatments for wheezing (asthma) included nebulized epinephrine (3/33) and magnesium (2/33). No agencies included steroids in their treatment protocols (0/33). CONCLUSION Protocols for pediatric respiratory distress vary widely across the state of California, especially among those for stridor (croup) and wheezing in < 24 months (bronchiolitis). The evidence-based recommendations that we present for the prehospital treatment of these conditions may be useful for EMS medical directors tasked with creating and revising these protocols.

Abstract
UNLABELLED International guidelines have recommended the use of inhaled beta-2 agonists and systemic corticosteroids (SCs) as the first-line treatment for acute asthma. OBJECTIVE To evaluate the evidence for the efficacy of inhaled corticosteroids (ICSs) in addition to SCs compared to SCs alone in children with acute asthma in the emergency department (ED) or during hospitalization. DATA SOURCES Five electronic databases were searched. STUDY SELECTION All randomized clinical trials that compared ICS (via nebulizer or metered dose inhaler) plus SC (oral or parenteral) with placebo (or standard care) plus SC were included without language restriction. DATA EXTRACTION Two reviewers independently reviewed all the studies. The primary outcomes were hospital admission and hospital length of stay (LOS), and secondary outcomes were readmissions during follow-up, ED-LOS, lung function, asthma clinical score, oxygen saturation, and heart and respiratory rates. RESULTS Nine studies (n = 1473) met the inclusion criteria. In all the studies, the ICS was budesonide. Compared to SC alone, adding budesonide to SC did not affect hospitalization rate, but decreased hospital LOS by more than 1 day (MD = -29.08 hours [-39.9 to -18.3]; I2 = 0%, P = < .00001). Moreover, adding budesonide significantly improved the acute asthma severity score among patients at ED. CONCLUSIONS Compared to SC alone, adding budesonide to SC does not affect the hospitalization rate, but decreases the LOS and improves the acute asthma score in children in an ED setting.

Nurse-driven Clinical Pathway Based on an Innovative Asthma Score Reduces Admission Time for Children. Pediatr Qual Saf 2020; 5:e344.

Abstract
We recently demonstrated that an innovative asthma score independent of auscultation could accurately predict the requirement for bronchodilator nebulization compared to the physician's routine clinical judgment to administer bronchodilators. We aimed to standardize inpatient care for children with acute asthma by implementing a clinical pathway based on this innovative asthma score. Methods We designed a nurse-driven clinical pathway. This pathway included standardized respiratory assessments and a protocol for the nursing staff to administer bronchodilators without a specific order from the physician. We compared the length of stay and the number of readmissions to a historical cohort. Results Seventy-nine patients with moderate acute asthma completed the pathway. We obtained a total of 858 Childhood asthma scores in these patients, with a median of 11 scores per patient (interquartile range 8-17). Patients treated according to the nurse-driven protocol were 3.3 times more likely to be discharged earlier (hazard ratio, 3.29; 95% confidence interval, 2.33-4.66; P < 0.05), and length of stay was significantly reduced (median 28 versus 53 h) compared to the historical standard practice. On request, the attending physician assessed the patient's respiratory status 42 times (4.9% of all childhood asthma score assessments). Patient safety was not compromised, and none of the patients were removed from the pathway. In each group, we readmitted two (2.5%) patients within 1 week after discharge. Conclusion This nurse-driven clinical pathway for children with acute asthma based on an asthma score independent of auscultation findings significantly decreased length of stay without compromising patient safety.

Abstract
OBJECTIVES To prospectively evaluate quality of life (QoL) and psychosocial outcomes in children with severe acute asthma (SAA) after pediatric intensive care (PICU) admission compared to children with SAA who were admitted to a general ward (GW). In addition, we assessed post-traumatic stress (PTS) and asthma-related QoL in the parents. METHODS A preplanned follow-up of 3-9 months of our nationwide prospective multicenter study, in which children with SAA admitted to a Dutch PICU (n=110) or GW (n=111) were enrolled between 2016-2018. Asthma-related QoL, PTS symptoms, emotional and behavioral problems, and social impact in children and/or parents were assessed with validated web-based questionnaires. RESULTS We included 100 children after PICU and 103 after GW admission, with a response rate of 50% for the questionnaires. Median time to follow-up was 5 months (range 1-12 months). Time to reach full schooldays after admission was significantly longer in the PICU group (mean of 10 vs 4 days, p=0.001). Parents in the PICU group reported more PTS symptoms (intrusion p=0.01, avoidance p=0.01, arousal p=0.02) compared to the GW group. CONCLUSION No significant differences were found between PICU and GW children on self-reported outcome domains, except for the time to reach full schooldays. PICU parents reported PTS symptoms more often than the GW group. Therefore, monitoring asthma symptoms and psychosocial screening of children and parents after PICU admission should both be part of standard care after SAA. This should identify those who are at risk for developing PTSD, in order to timely provide appropriate interventions. This article is protected by copyright. All rights reserved.

[PMID: 32832524 PMCID: PMC7430140 DOI: 10.1183/23120541.00126-2020] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2020] [Accepted: 05/06/2020] [Indexed: 01/08/2023] Open
Abstract
Rationale Severe acute asthma (SAA) can be fatal, but is often preventable. We previously observed in a retrospective cohort study, a three-fold increase in SAA paediatric intensive care (PICU) admissions between 2003 and 2013 in the Netherlands, with a significant increase during those years of numbers of children without treatment of inhaled corticosteroids (ICS). Objectives To determine whether steroid-naïve children are at higher risk of PICU admission among those hospitalised for SAA. Furthermore, we included the secondary risk factors tobacco smoke exposure, allergic sensitisation, previous admissions and viral infections. Methods A prospective, nationwide multicentre study of children with SAA (2–18 years) admitted to all Dutch PICUs and four general wards between 2016 and 2018. Potential risk factors for PICU admission were assessed using logistic regression analyses. Measurements and main results 110 PICU and 111 general ward patients were included. The proportion of steroid-naïve children did not differ significantly between PICU and ward patients. PICU children were significantly older and more exposed to tobacco smoke, with symptoms >1 week prior to admission. Viral susceptibility was not a significant risk factor for PICU admission. Conclusions Children with SAA admitted to a PICU were comparable to those admitted to a general ward with respect to ICS treatment prior to admission. Preventable risk factors for PICU admission were >7 days of symptoms without adjustment of therapy and exposure to tobacco smoke. Physicians who treat children with asthma must be aware of these risk factors. Preventable risk factors for PICU admission among those with severe acute asthma are >7 days of symptoms without adjustment of therapy and environmental exposure to tobacco smoke, underlining the importance of smoking cessation of caregivershttps://bit.ly/3ezPzxT

J Steroid Biochem Mol Biol 2020; 201:105692. [PMID: 32380236 DOI: 10.1016/j.jsbmb.2020.105692] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/01/2019] [Revised: 04/28/2020] [Accepted: 04/29/2020] [Indexed: 12/27/2022]
Abstract
Single nucleotide polymorphisms (SNPs) of the vitamin D receptor (VDR) gene have shown linkage and association with asthma development in multiple cohort studies. However, the majority of investigations have focused on asthma phenotypes in cohorts with stable disease. We investigated the relationship between VDR SNPs and the frequency and severity of acute episodes of wheeze/asthma in a cohort of Australian children, as the ability to identify children at risk of more severe exacerbations could lead to personalized and improved genotype-specific treatment pathways. We successfully genotyped five SNPs of the VDR gene (rs2525046, rs9729, rs1544410 (BsmI), rs22239179, and rs2228570 (FokI)) in 657 children presenting to a tertiary children's hospital with acute asthma, bronchiolitis, or a wheezing illness. The relationships between VDR SNPs and exacerbation severity scores, β2-agonist use, and frequency of respiratory exacerbations were analysed using multiple regression. The rs2525046 (FokI) CT genotype was associated with higher VDR mRNA intensity levels (p = 0.007) compared to the CC genotype. A trend towards significance (p=0.056) was identified between the rs2525046 TT genotype and higher VDR mRNA intensity levels compared to the CC genotype. Children with rs2228570 AA genotype had higher exacerbation severity scores (p=0.001) and poorer β2-agonist treatment response (doses at 6 h: p = 0.009 and 12 h: p=0.033) compared to those with the GG genotype. Children with rs1544410 (BsmI) TT genotype had lower exacerbation severity scores (p = 0.005) compared to those with the CC genotype. Children with rs2228570 GA genotype presented to and/or were admitted to hospital more times since birth with respiratory (p = 0.011) and wheezing (p = 0.021) illnesses than children with the GG genotype. No associations were identified between rs9729, rs2525046 and r2239179 polymorphisms and acute wheezing/asthma variables. These findings suggest that genetic variants at the VDR locus may play a role in acute wheeze/asthma severity in children.

Abstract
Asthma has been known as a prevalent chronic-type inflammatory disease in children, because of their narrower respiratory airways. The present study aimed to identify guidelines for children asthma treatments. Extensive research was conducted on biomedical and pharmacological bibliographic database PubMed, EMBASE, MEDLINE, LILACS database, global independent network of Cochrane, Science Direct and global health library of Global Index Medicus. A comprehensive literature review was carried out using the terms Pediatric Asthma, epidemiology, management, and related clinical guidelines published from 2000 to 2019. After the primary assessment, quick diagnosis, clinical practice guidelines are useful tools for proper management of pediatric Asthma. By setting proper guidelines for this particular population, a higher improvement in quality of management of of pediatric Asthma is expected. Given the differences between the recommendations arisen by BTS/SIGN and NICE guidelines, critical comparison of the evidence-base guidelines provide suggestions that have more in common than what might seems at the first glance. The analysis of the variations presented in the present article will assist clinicians to make accurate decisions regarding their patients.

Abstract
Most pediatric asthma guidelines offer evidence-based or best practice approaches to the management of asthma exacerbations but struggle with evidence-based approaches for severe acute asthma (SAA). We aimed to investigate current practices in children with SAA admitted to European pediatric intensive care units (PICUs), in particular, adjunct therapies, use of an asthma severity score, and availability of a SAA guideline. We designed a cross-sectional electronic survey across European PICUs. Thirty-seven PICUs from 11 European countries responded. In 8 PICUs (22%), a guideline for SAA management was unavailable. Inhaled beta-agonists and anticholinergics, combined with systemic steroids and IV MgSO4 was central in SAA treatment. Seven PICUs (30%) used a loading dose of a short-acting beta-agonist. Eighteen PICUs (49%) used an asthma severity score, with 8 different scores applied. Seventeen PICUs (46%) observed an increasing trend in SAA admissions.Conclusion: Variations in the treatment of children with SAA mainly existed in the use of adjunct therapies and asthma severity scores. Importantly, in 22% of the PICUs, a SAA guideline was unavailable. Standardizing SAA guidelines across PICUs in Europe may improve quality of care. However, the limited number of PICUs represented and the data compilation method are constraining our findings.What is Known:• Recent reports demonstrate increasing numbers of children with SAA requiring PICU admission in several countries across the world.• Most pediatric guidelines offer evidence-based approaches to the management of asthma exacerbations, but struggle with evidence-based approaches for SAA beyond these initial steps.What is New:• A large arsenal of adjunct therapies and 8 different asthma scores were used.• In a large number of PICUs, a written guideline for SAA management is lacking.

Abstract
Clinical assessment of the work of breathing (WOB) remains a cornerstone in respiratory support decision-making in the pediatric intensive care unit (PICU). In this study, we determined the interobserver agreement of 30 observers (PICU physicians and nurses) on WOB and multiple signs of effort of breathing in 10 spontaneously breathing children admitted to the PICU. By reliability analysis, the agreement on overall WOB was poor to moderate, and only three separate signs of effort of breathing (breathing rate, stridor, and grunting) showed moderate-to-good interobserver reliability. We conclude that the interobserver agreement on the clinical WOB judgment among PICU physicians and nurses is low.

Abstract
BACKGROUND In asthmatic children, respiratory pathogens are identified in 60%-80% of asthma exacerbations, contributing to a significant burden of illness. The role of pathogens in the clinical evolution of exacerbations is unknown. OBJECTIVE We systematically reviewed the association between the presence of pathogens and clinical outcomes in children with an asthma exacerbation. METHOD PubMed, EMBASE, BIOSIS, and the Cochrane Central Register of Controlled Trials were searched up to October 2016 for studies reporting on respiratory pathogen exposure and clinical outcome. The Risk of Bias in Non-Randomized Studies of Interventions tool was used for quality assessment. RESULTS Twenty-eight observational studies (N = 4,224 children) reported on 112 different associations between exposure to any pathogen (n = 45), human rhinovirus (HRV; n = 34), atypical bacteria (n = 21), specific virus (n = 11), or bacteria (n = 1) and outcomes of exacerbation severity (n = 26), health care use (n = 38), treatment response (n = 19), and morbidity (n = 29). Restricting the analysis only to comparisons with a low to moderate risk of bias, we observed an association between HRV and higher exacerbation severity on presentation (regression p = .016) and between the presence of any pathogen and emergency department treatment failure (odds ratio [OR] = 1.57; 95% CI 1.04% to 2.37%). High-quality evidence for effect on morbidity or health care use is lacking. CONCLUSIONS Further research on the role of pathogen-treatment interaction and outcomes is required to inform the need for point-of-care, real-time testing for pathogens. Studies with a sufficiently large sample size that address selection bias, correctly adjust for confounding, and rigorously report core patient-centred outcomes are necessary to improve knowledge.

Abstract
BACKGROUND Exhaled breath temperature (EBT) has been suggested as a non-invasive marker of airway inflammation in asthma. There have been no studies examining longitudinal changes in EBT following asthma attacks. OBJECTIVE To investigate changes in EBT during and after an asthma attack and to relate these changes to changes in respiratory physiological measurements. METHODS We evaluated 38 hospitalized children aged 5-18 years diagnosed with an asthma attack. Spirometry was performed upon hospitalization. During hospitalization, EBT, peak expiratory flow rate (PEFR), and asthma score were measured daily. These tests were repeated 1 week and 1 month after discharge. The overall PEFR change, temporal changes in plateau values at the end of expiration, and time-dynamic associations were evaluated using linear mixed models. RESULTS FEV1 was lower at admission than at discharge (63.3 ± 24 vs 99.5 ± 14 percent of predicted, P < 0.001). The EBT was higher at admission than at 1 week after discharge (34.1°C [range: 33.9-34.8°C] vs 33.6°C [range: 33.0-34.2°C], P = 0.007); overall, EBTs decreased over time (P = 0.007). Among individual subjects, decreased EBT was correlated with increased PEFR over time. Furthermore, plateau values at the end of expiration had a time-dependent, dynamic association with the PEFR during hospitalization (P = 0.005) and between asthma attack onset and asthma status stabilization (P = 0.032). CONCLUSIONS The EBT was elevated during asthma attacks and gradually decreased until asthma was well controlled. The EBT may be a useful, non-invasive tool for monitoring asthma control in children.

Abstract
Asthma exacerbations are triggered by rhinovirus infections. We employed a systems biology approach to delineate upper-airway gene network patterns underlying asthma exacerbation phenotypes in children. Cluster analysis unveiled distinct IRF7hi versus IRF7lo molecular phenotypes, the former exhibiting robust upregulation of Th1/type I IFN responses and the latter an alternative signature marked by upregulation of cytokine and growth factor signaling and downregulation of IFN-γ. The two phenotypes also produced distinct clinical phenotypes. For IRF7lo children, symptom duration prior to hospital presentation was more than twice as long from initial symptoms (p = 0.011) and nearly three times as long for cough (p < 0.001), the odds ratio of admission to hospital was increased more than 4-fold (p = 0.018), and time to recurrence was shorter (p = 0.015). In summary, our findings demonstrate that asthma exacerbations in children can be divided into IRF7hi versus IRF7lo phenotypes with associated differences in clinical phenotypes.

Abstract
OBJECTIVE To compare the efficacy of a breath-enhanced and a conventional jet nebulizer in the treatment of children with moderate to severe acute asthma. STUDY DESIGN We enrolled subjects between 6 and 18 years of age presenting to the emergency department (ED) with acute asthma and an initial forced expiratory volume in 1 second (FEV1) <70% of predicted. We excluded patients with chronic disease, who required immediate resuscitation, or failed spirometry. Subjects were randomized to breath-enhanced or conventional jet delivery of a 5-mg albuterol treatment. Our primary outcome was change in FEV1, and secondary outcomes included change in clinical asthma scores, ED length of stay, disposition, and side effects. Student t test and multivariable linear regression were used to evaluate the primary outcome. RESULTS In total, 497 patients were assessed for eligibility with 118 enrolled and 107 subjects available for analysis of the primary outcome. Improvement in FEV1 was significantly greater with conventional jet nebulizer (mean ΔFEV1 +13.8% vs +9.1%, P = .04). This difference remained significant after adjustment for baseline differences. Subgroup analysis of 57 subjects with spirometry meeting American Thoracic Society/European Respiratory Society guidelines yielded similar results (mean ΔFEV1 +14.5% vs +8.5%, P=.03). There were no significant differences in clinical asthma scores, ED length of stay, disposition, or side effects. CONCLUSIONS Albuterol delivered via conventional jet nebulizer resulted in significantly greater improvement in FEV1 than albuterol delivered by breath-enhanced nebulizer, without significant differences in clinical measures. Conventional jet nebulizers may deliver albuterol to children with acute asthma more effectively than breath-enhanced nebulizers. TRIAL REGISTRATION ClinicalTrials.gov: NCT02566902.

Acad Emerg Med 2018; 25:1463-1470. [PMID: 30382605 DOI: 10.1111/acem.13655] [Citation(s) in RCA: 50] [Impact Index Per Article: 8.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2018] [Revised: 10/24/2018] [Accepted: 10/29/2018] [Indexed: 11/27/2022]
Abstract
OBJECTIVES Pediatric asthma is a leading cause of emergency department (ED) utilization and hospitalization. Earlier identification of need for hospital-level care could triage patients more efficiently to high- or low-resource ED tracks. Existing tools to predict disposition for pediatric asthma use only clinical data, perform best several hours into the ED stay, and are static or score-based. Machine learning offers a population-specific, dynamic option that allows real-time integration of available nonclinical data at triage. Our objective was to compare the performance of four common machine learning approaches, incorporating clinical data available at the time of triage with information about weather, neighborhood characteristics, and community viral load for early prediction of the need for hospital-level care in pediatric asthma. METHODS Retrospective analysis of patients ages 2 to 18 years seen at two urban pediatric EDs with asthma exacerbation over 4 years. Asthma exacerbation was defined as receiving both albuterol and systemic corticosteroids. We included patient features, measures of illness severity available in triage, weather features, and Centers for Disease Control and Prevention influenza patterns. We tested four models: decision trees, LASSO logistic regression, random forests, and gradient boosting machines. For each model, 80% of the data set was used for training and 20% was used to validate the models. The area under the receiver operating characteristic (AUC) curve was calculated for each model. RESULTS There were 29,392 patients included in the analyses: mean (±SD) age of 7.0 (±4.2) years, 42% female, 77% non-Hispanic black, and 76% public insurance. The AUCs for each model were: decision tree 0.72 (95% confidence interval [CI] = 0.66-0.77), logistic regression 0.83 (95% CI = 0.82-0.83), random forests 0.82 (95% CI = 0.81-0.83), and gradient boosting machines 0.84 (95% CI = 0.83-0.85). In the lowest decile of risk, only 3% of patients required hospitalization; in the highest decile this rate was 100%. After patient vital signs and acuity, age and weight, followed by socioeconomic status (SES) and weather-related features, were the most important for predicting hospitalization. CONCLUSIONS Three of the four machine learning models performed well with decision trees preforming the worst. The gradient boosting machines model demonstrated a slight advantage over other approaches at predicting need for hospital-level care at the time of triage in pediatric patients presenting with asthma exacerbation. The addition of weight, SES, and weather data improved the performance of this model.

Abstract
BACKGROUND Although previous studies have shown benefits of nebulized hypertonic saline (HS) for improving airway clearance and shortening hospitalization in infants with bronchiolitis, prospective blinded studies in preschool children with acute viral wheezing are limited. OBJECTIVES To determine nebulized 3% HS efficacy in young children admitted with acute viral wheezing. METHODS This double-blind, randomized controlled trial was conducted in children aged 6 months to 5 years admitted with acute viral wheezing from July 1st to December 31st 2016. Patients were randomized to receive inhalation of 2.5 mg salbutamol dissolved in either 3% HS or normal saline (NS). Clinical data, asthma clinical severity score, and length of hospital stay (LOS) were recorded. RESULTS A total of 47 patients were enrolled (22 in HS and 25 in NS) without significant differences in demographic data and baseline clinical scores. Median LOS and median time of oxygen therapy were significantly shorter in HS than NS group: 48 versus 72 h, P = 0.021 and 36 versus 72 h, P = 0.025, respectively. HS patients had significantly improved asthma clinical severity scores, respiratory rates and oxygen saturation at 12 h compared to NS group (P-value 0.042, 0.032, and 0.043). There were no adverse events. CONCLUSION In children under 5 years admitted with acute viral wheezing, nebulized hypertonic saline/salbutamol significantly shortened hospital stay length, time of oxygen therapy, and improved asthma clinical severity score faster than normal saline/salbutamol.

Abstract
Guideline-based management of asthma focuses on disease severity and choosing the appropriate medical therapy to control symptoms and reduce the risk of exacerbations. However, irrespective of asthma severity and often despite optimal medical therapy, patients may experience acute exacerbations of symptoms and a loss of disease control. Asthma exacerbations are most commonly triggered by viral respiratory infections, particularly with human rhinovirus. Given the importance of these events to asthma morbidity and health care costs, we will review common inciting factors for asthma exacerbations and approaches to prevent and treat these events.

Abstract
OBJECTIVES To identify associations between use of ipratropium and/or intravenous magnesium and outcomes of children hospitalized with acute asthma exacerbations and treated with continuous albuterol. METHODS Secondary analysis of data from children prospectively enrolled in the multicenter Ohio Pediatric Asthma Repository restricted to only children who were treated with continuous albuterol in their initial inpatient location. Children were treated with adjunctive therapies per the clinical team. RESULTS Among 242 children who received continuous albuterol, 94 (39%) received ipratropium only, 13 (5%) received magnesium alone, 42 (17%) received both, and 93 (38%) received neither. The median duration of continuous albuterol was 7.0 (interquartile range [IQR]: 2.8-12.0) hours. Ipratropium use was associated with a shorter duration of continuous albuterol (4.9 [IQR: 2.0-10.0] hours) compared with dual therapy (11.0 [IQR: 5.6-28.6] hours; P = .001), but magnesium use was not (7.5 [IQR: 2.5-16.0] hours; P = .542). In Cox proportional models (adjusted for hospital, demographics, treatment location, and respiratory failure), magnesium was associated with longer durations of continuous albuterol (hazard ratio, 0.54 [95% confidence interval: 0.37-0.77]; P < .001) and hospitalization (hazard ratio, 0.41 [95% confidence interval: 0.28-0.60]; P < .001), but ipratropium was not. CONCLUSIONS Ipratropium and magnesium were both often used in children with severe asthma hospitalizations that required continuous albuterol therapy. Magnesium use was associated with unfavorable outcomes, possibly reflecting preferential treatment to patients with more severe cases and differing practices between centers. Given the high prevalence of asthma, wide variations in practice, and the potential to improve outcomes and costs, prospective trials of these adjunctive therapies are needed.

Abstract
UNLABELLED In this study, we aimed to identify characteristics of (unscheduled) revisits and its optimal time frame after Emergency Department (ED) discharge. Children with fever, dyspnea, or vomiting/diarrhea (1 month-16 years) who attended the ED of Erasmus MC-Sophia, Rotterdam (2010-2013), the Netherlands, were prospectively included. Three days after ED discharge, we applied standardized telephonic questionnaires on disease course and revisits. Multivariable logistic regression analysis was used to identify independent characteristics of revisits. Young age, parental concern, and alarming signs and symptoms (chest wall retractions, ill appearance, clinical signs of dehydration, and tachypnea) were associated with revisits (n = 527) in children at risk for serious infections discharged from the ED (n = 1765). Children revisited the ED within a median of 2 days (IQR 1.0-3.0), but this was proven to be shorter in children with vomiting/diarrhea (1.0 day (IQR 1.0-2.0)) compared to children with fever or dyspnea (2.0 (IQR 1.0-3.0)). CONCLUSION Young age, parental concern, and alarming signs and symptoms (chest wall retractions, ill appearance, clinical signs of dehydration, and tachypnea) were associated with emergency health care revisits in children with fever, dyspnea, and vomiting/diarrhea. These characteristics could help to define targeted review of children during post-discharge period. We observed a disease specific and differential timing of control revisits after ED discharge. What is Known • Fever, dyspnea, and vomiting/diarrhea are major causes of emergency care attendance in children. • As uncertainty remains on uneventful recovery, patients at risk need to be identified on order to improve safety netting after discharge from the ED. What is New • In children with fever, dyspnea, and vomiting/diarrhea, young age, parental concern and chest wall retractions, ill appearance, clinical signs of dehydration, and tachypnea help to define targeted review of children during the post-discharge period. • A revisit after ED discharge is disease-specific and seems to be shorter for children with vomiting/diarrhea than others.

Abstract
OBJECTIVES We aimed to evaluate the seasonal variations of acute asthma presentation in children and the utility of the pediatric asthma score (PAS) and its components in early admission prediction. METHODS As part of a randomized controlled trial addressing the clinical efficacy of budesonide nebulization in the treatment of acute asthma in children, the PAS was measured at baseline, 1st, 2nd, 3rd, and 4th h from the start of medications. Decision of admission was taken at or beyond the 2nd h. RESULTS Out of a total 906 emergency department (ED) visits with moderate-to-severe acute asthma, 157 children were admitted. June to September had the lowest number of visits. The admission-to-discharge ratio varied throughout the year. During the ED stay, between baseline and 3rd h, admission predictability of the total score improved progressively with a small difference between the 2nd and 3rd h. The total score remained the strongest predictor of admission at every time point compared to its individual components. The drop of PAS from baseline to the 2nd h was not a good predictor of admission. Oxygen saturation (OS) and respiratory rate (RR) had relatively higher predictability than other components. CONCLUSIONS Decision of admission could be made to many children with moderate-to-severe acute asthma at the 2nd h of ED stay based on their total PAS. OS and RR should be part of any scoring system to evaluate acute asthma in children.

Abstract
To determine the prevalence of human rhinovirus (HRV) infection in children with acute asthma exacerbations, investigation of HRV viral load and severity of asthma exacerbations is also required. Nasopharyngeal aspirates and swabs were collected and assessed for respiratory viruses. HRV-positive samples were sequenced to identify types and determine viral load. Outpatients with asthma exacerbations underwent follow-up evaluations, their swabs were collected and clinical outcomes were recorded at their next clinic visit 4 weeks later. One hundred forty-three inpatients and 131 outpatients, including 88 patients with asthma exacerbations and 43 controls with stable asthma were recruited. HRV-A was mainly detected in September and February (45.5% and 33.3%, respectively), while HRV-C was mainly detected in November and April (70.0% and 55.6%, respectively). HRV-C was the primary type and was primarily found in inpatients with severe asthma exacerbations. HRV-A viral load in the group of inpatients with severe exacerbations was higher than in the mild and moderate groups (P < 0.001 and P = 0.022). The HRV-A viral load of both inpatients and outpatients was higher than that of HRV-C (P < 0.001 and P = 0.036). The main genotypes were HRV-C53 and HRV-A20 among inpatients, and this genotype caused more severe clinical manifestations. HRV persisted for no more than 4 weeks, and their symptoms or signs of disease were well-controlled well. HRV-C was most frequently detected in asthma exacerbations. HRV-A with high viral load led to severe asthma exacerbations.

Abstract
INTRODUCTION There are countless clinical respiratory scales for acute dyspnoea. Most healthcare professionals choose one based on previous personal experience or following local practice, unaware of the implications of their choice. The lack of critical comparisons between those different tools has been a widespread problem that only recently has begun to be addressed via score validation studies. Here we try to assess and compare the quality criteria of measurement properties of acute dyspnoea scores. Areas covered: A literature review was conducted by searching the PubMed database. Forty-five documents were deemed eligible as they reported the use or building of clinical scales, using at least two parameters, and applied these to an acute episode of respiratory dyspnoea. Our primary focus was the description of the validity, reliability and utility of 41 suitable scoring instruments. Differences in sample selection, study design, rater profiles and potential methodological shortcomings were also addressed. Expert commentary: All acute dyspnoea scores lack complete validation. In particular, the areas of measurement error and interpretability have not been addressed correctly by any of the tools reviewed. Frequent modification of pre-existing scores (in items composition and/or name), differences in study design and discrepancies in reviewed sources also hinder the search for an adequate tool.

Abstract
OBJECTIVE The objective of this study was to determine if a rapid albuterol delivery pathway with a breath-enhanced nebulizer can reduce emergency department (ED) length of stay (LOS), while maintaining admission rates and side effects, when compared to a traditional asthma pathway with a standard jet nebulizer. METHODS Children aged 3-18 presenting to a large urban pediatric ED for asthma were enrolled if they were determined by pediatric asthma score to have a moderate to severe exacerbation. Subjects were randomized to either a standard treatment arm where they received up to 2 continuous albuterol nebulizations, or a rapid albuterol arm where they received up to 4 rapid albuterol treatments with a breath-enhanced nebulizer, depending on severity scoring. The primary endpoint was ED LOS from enrollment until disposition decision. Asthma scores, albuterol dose, side effects, and return visits were also recorded. RESULTS A total of 50 subjects were enrolled (25 in each arm). The study LOS was shorter in the rapid albuterol group (118 vs. 163 minutes, p = 0.0002). When total ED LOS was analyzed, the difference was no longer statistically significant (192 vs. 203 minutes, p = 0.65). There were no statistically significant differences with respect to admission rates, asthma score changes, side effects, or return visits. CONCLUSION A rapid albuterol treatment pathway that utilizes a breath-enhanced nebulizer is an effective alternative to traditional pathways that utilize continuous nebulizations for children with moderate to severe asthma exacerbations in the ED.

Abstract
BACKGROUND Despite growing evidence suggesting potential association between innate and adaptive immunity in viral-induced acute asthma, there is paucity of data in this area. OBJECTIVE This study aimed to investigate the association of innate and adaptive immunity with acute asthma attacks by analysing the role of IFN-γ-inducible protein 10 (IP-10), TLR2, cathelicidin, vitamin D and cytokines. MATERIAL AND METHODS This prospective study included 33 patients with viral-induced acute asthma and 30 children with controlled asthma. Nasopharyngeal swab samples were collected for virus identification and asthma attack scores assessed in acute asthma group. Blood sampling for IP-10, TLR2, cathelicidin, vitamin D levels, and spirometric indices were employed. RESULTS Serum IP-10 and cathelicidin levels of acute asthma group were significantly higher and vitamin D levels were lower than controlled asthma group (IP-10; p=0.006, cathelicidin; p=0.002, vitamin D; p<0.001). Serum IP-10 levels showed a significant negative correlation with age (p=0.009), TLR2 (p=0.05) and spirometric indices (p=0.002) in all asthmatics and a significant positive correlation with parameters of asthma attack severity (p=0.03) in acute asthma group. Higher cathelicidin values showed significant positive relation to IP-10 (beta coefficient: 33, p=0.02). Serum IP-10 levels higher than 38.9pg/ml (sensitivity: 85%, specificity: 47%, p=0.002) were predictive of virus-induced asthma. Serum IP-10 and vitamin D levels were found to be significantly related to viral-asthma attacks (IP-10; aOR: 8.93, p=0.03 and vitamin D; aOR: 0.82, p=0.001). CONCLUSIONS Innate immunity biomarkers such as serum IP-10 and cathelicidin can be used to predict viral-induced acute asthma. These biomarkers may provide potential new treatment targets for acute asthma.

Abstract
INTRODUCTION Higher parasympathetic tone has been reported in asthmatics. In general, cholinergic contractile tone is increased by airway inflammation associated with asthma. Nevertheless, the role of muscarinic antagonists for the treatment of asthma has not yet been clearly defined. Areas covered: The use of SAMAs and LAMAs in asthma has been examined and discussed according with the published evidence. Particular attention has been given to the large Phase III clinical trial program designed to evaluate the efficacy and safety of tiotropium respimat added to standard treatment in adults, adolescents and children with persistent asthma across the spectrum of asthma severity. Expert commentary: The current evidence is that in patients with poorly controlled severe asthma despite the use of ICS and LABA, the addition of tiotropium significantly increases the time to the first severe exacerbation and provides a modest but sustained bronchodilation. Identical results should be produced using other LAMAs. In any case, the documentation that, at least in animal or in vitro models, LAMAs show significant anti-inflammatory and anti-proliferative capacities and are able to inhibit airway remodeling induced by allergens makes a strong presumption that the use of LAMAs in asthma may go beyond the simple bronchodilator effect.

Tiotropium Respimat Is Effective for the Treatment of Asthma at a Dose Lower Than That for Chronic Obstructive Pulmonary Disease. Ann Am Thorac Soc 2016; 13:173-9.

Abstract
Anticholinergic drug products are not part of the current treatment paradigm for asthma, despite their widespread availability for chronic obstructive pulmonary disease (COPD) and interest in their use for asthma. Published study results, mostly of short duration and primarily with ipratropium and tiotropium, have revealed inconsistent efficacy results. Consequently, the role of inhaled anticholinergic drugs in the treatment of asthma has been unclear. This commentary discusses and comments on data from five clinical trials in adults that were submitted by Boehringer Ingelheim to the U.S. Food and Drug Administration to support approval of tiotropium delivered by the Respimat device (Spiriva Respimat) for the treatment of asthma. These trials provided substantial evidence that supported the approval of Spiriva Respimat at a recommended dose of 2.5 μg once daily for asthma. Notably, in trials that evaluated two doses of tiotropium, 2.5 μg and 5 μg (the dose approved for COPD), pulmonary function measures for Spiriva Respimat 2.5 μg once daily were better overall than those obtained for the 5-μg once-daily dose, thus justifying selection of the lower dose for asthma. Spiriva Respimat represents the first new class of drug approved by the U.S. Food and Drug Administration for the treatment of asthma in more than a decade. The availability of Spiriva Respimat for asthma along with other novel therapies currently under development has the potential to impact asthma treatment guidelines.

Abstract
BACKGROUND Genetic associations of the response to inhaled corticosteroids (ICSs) during an asthma exacerbation are unknown. OBJECTIVE To evaluate the role of genetic variants in the therapeutic response to high-dose ICS in children with moderate-to-severe asthma exacerbations. METHODS Eighty-two children (56 boys/26 girls, mean age 9.6 ± 3.2 years) with moderate-severe asthma exacerbation were genotyped for eight single-nucleotide polymorphisms that were a priori associated with ICS response in chronic asthma treatment: glucocorticosteroid receptor (NR3C1) rs41423247; corticotrophin-releasing hormone receptor1 (CRHR1) rs242939, rs242941, and rs1876828; T-box 21 (TBX21) rs2240017; glucocorticoid-induced transcript 1 (GLCCl1); and T gene rs3099266 and rs2305089. Children were treated with a single high-dose (4000 μg) fluticasone propionate given by a nebulizer followed by 1000 μg/day of inhaled fluticasone propionate for 6 days. Primary outcome measure was the improvement in FEV1 at 4 h. RESULTS Mean FEV1 was 71.7 ± 14.2% at presentation. Overall, fluticasone treatment resulted in a significant improvement in asthma score and FEV1 (p < 0.0001 for both). Children with the GG genotype at NR3C1 rs41423247 (n = 26) had a higher improvement in FEV1 [24.2% (interquartile range 11.5-36.3)] compared to those with CG+CC (n = 19), [7.9% (interquartile range 6.1-24.6) (p = 0.006)]. CONCLUSION Homozygosity for the G allele at rs41423247 of the glucocorticosteroid receptor (NR3C1) gene is associated with a higher improvement in FEV1 at 4 h in children with moderate-to-severe asthma exacerbation treated with high-dose ICS. This observation may have important clinical implications especially for children who use systemic steroids frequently for recurrent asthma exacerbations.

Abstract
Asthma is one of the most common chronic pediatric diseases. Patients with asthma often present to the emergency department for treatment for acute exacerbations. These patients may not have a primary care physician or primary care home, and thus are seeking care in the emergency department. Asthma care in the emergency department is multifaceted to treat asthma patients appropriately and provide quality care. National and international guidelines exist to help drive clinical care. Electronic and paper-based tools exist for both physicians and patients to help improve emergency, home, and preventive care. Treatment of patients with asthma should include the acute exacerbation, long-term management of controller medications, and controlling triggers in the home environment. We will address the current state of asthma research in emergency medicine in the US, and discuss some of the resources being used to help provide a medical home and improve care for patients who suffer from acute asthma exacerbations.

Abstract
BACKGROUND In acute dyspnoeic children, assessment of dyspnoea severity and treatment response is frequently based on clinical dyspnoea scores. Our study aim was to validate five commonly used paediatric dyspnoea scores. METHODS Fifty children aged 0-8 years with acute dyspnoea were clinically assessed before and after bronchodilator treatment, a subset of 27 children were videotaped and assessed twice by nine observers. The observers scored clinical signs necessary to calculate the Asthma Score (AS), Asthma Severity Score (ASS), Clinical Asthma Evaluation Score 2 (CAES-2), Pediatric Respiratory Assessment Measure (PRAM) and respiratory rate, accessory muscle use, decreased breath sounds (RAD). RESULTS A total of 1120 observations were used to assess fourteen measurement properties within domains of validity, reliability and utility. All five dyspnoea scores showed overall poor results, scoring insufficiently on more than half of the quality criteria for measurement properties. The AS and PRAM were the most valid with good values on six and moderate values on three properties. Poor results were mainly due to insufficient measurement properties in the validity and reliability domains whereas utility properties were moderate to good in all scores. CONCLUSION This study shows that commonly used dyspnoea scores show insufficient validity and reliability to allow for clinical use without caution.

Abstract
OBJECTIVE The objective was to determine the occurrence of, and the factors associated with, diastolic hypotension and troponin elevation or electrocardiogram (ECG) ST-segment changes in a convenience sample of children with moderate to severe asthma receiving continuous albuterol nebulization. METHODS This was a prospective, descriptive study in a pediatric emergency department and an intensive care unit of a tertiary academic center. Fifty children with moderate to severe asthma (clinical asthma score > 8) who received 10 to 15 mg/hour continuous albuterol for >2 hours between June 5, 2007, and February 4, 2008, were approached. Hourly diastolic blood pressures were recorded. Cardiac troponin I (cTnI) and ECG tracings were obtained following the first 2 hours of albuterol and then subsequently every 12 hours while receiving continuous albuterol. Main outcome measures were: 1) incidence of diastolic hypotension, 2) incidence of troponin elevation, and 3) incidence of ECG ST-depression. RESULTS Fifty patients were enrolled. Thirty-three (66%) patients developed diastolic hypotension during the first 6 hours of continuous albuterol. Diastolic blood pressure declined from baseline at 1-6 hours (p < 0.01 vs. baseline). Twelve patients (24%) had elevated cTnI, 15 patients (30%) had ST-segment change, four patients (8%) had both, and 23 patients (46%, 95% confidence interval [CI] = 32 to 60) had either a cTnI elevation or an ECG ST-segment change. Troponin elevation and diastolic hypotension were not associated (RR = 1.2, 95% CI = 0.6 to 2.3). CONCLUSIONS In a subset of children with moderate to severe asthma, diastolic hypotension, troponin elevation, and ECG ST-segment change occur during administration of continuous albuterol. Future studies are necessary to determine the clinical significance of these findings.

Abstract
Asthma is the most common chronic illness in childhood. Although the vast majority of children with acute asthma exacerbations do not require critical care, some fail to respond to standard treatment and require escalation of support. Children with critical or near-fatal asthma require close monitoring for deterioration and may require aggressive treatment strategies. This review examines the available evidence supporting therapies for critical and near-fatal asthma and summarizes the contemporary clinical care of these children. Typical treatment includes parenteral corticosteroids and inhaled or intravenous beta-agonist drugs. For children with an inadequate response to standard therapy, inhaled ipratropium bromide, intravenous magnesium sulfate, methylxanthines, helium-oxygen mixtures, and non-invasive mechanical support can be used. Patients with progressive respiratory failure benefit from mechanical ventilation with a strategy that employs large tidal volumes and low ventilator rates to minimize dynamic hyperinflation, barotrauma, and hypotension. Sedatives, analgesics and a neuromuscular blocker are often necessary in the early phase of treatment to facilitate a state of controlled hypoventilation and permissive hypercapnia. Patients who fail to improve with mechanical ventilation may be considered for less common approaches, such as inhaled anesthetics, bronchoscopy, and extracorporeal life support. This contemporary approach has resulted in extremely low mortality rates, even in children requiring mechanical support.
