A novel syndrome of silent rhinovirus-associated bronchoalveolitis in children with recurrent wheeze. J Allergy Clin Immunol 2024; 154:571-579.e6. [PMID: 38761997 DOI: 10.1016/j.jaci.2024.04.027] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2023] [Revised: 04/01/2024] [Accepted: 04/19/2024] [Indexed: 05/20/2024]
Abstract
BACKGROUND Rhinovirus (RV) infections trigger wheeze episodes in children. Thus, understanding of the lung inflammatory response to RV in children with wheeze is important. OBJECTIVES This study sought to examine the associations of RV on bronchoalveolar lavage (BAL) granulocyte patterns and biomarkers of inflammation with age in children with treatment-refractory, recurrent wheeze (n = 616). METHODS Children underwent BAL to examine viral nucleic acid sequences, bacterial cultures, granulocyte counts, and phlebotomy for both general and type-2 inflammatory markers. RESULTS Despite the absence of cold symptoms, RV was the most common pathogen detected (30%), and when present, was accompanied by BAL granulocytosis in 75% of children. Compared to children with no BAL pathogens (n = 341), those with RV alone (n = 127) had greater (P < .05) isolated neutrophilia (43% vs 16%), mixed eosinophils and neutrophils (26% vs 11%), and less pauci-granulocytic (27% vs 61%) BAL. Children with RV alone furthermore had biomarkers of active infection with higher total blood neutrophils and serum C-reactive protein, but no differences in blood eosinophils or total IgE. With advancing age, the log odds of BAL RV alone were lower, 0.82 (5th-95th percentile CI: 0.76-0.88; P < .001), but higher, 1.58 (5th-95th percentile CI: 1.01-2.51; P = .04), with high-dose daily corticosteroid treatment. CONCLUSIONS Children with severe recurrent wheeze often (22%) have a silent syndrome of lung RV infection with granulocytic bronchoalveolitis and elevated systemic markers of inflammation. The syndrome is less prevalent by school age and is not informed by markers of type-2 inflammation. The investigators speculate that dysregulated mucosal innate antiviral immunity is a responsible mechanism.

Efficacy of oral corticosteroids for acute preschool wheeze: a systematic review and individual participant data meta-analysis of randomised clinical trials. THE LANCET. RESPIRATORY MEDICINE 2024; 12:444-456. [PMID: 38527486 DOI: 10.1016/s2213-2600(24)00041-9] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/18/2023] [Revised: 02/12/2024] [Accepted: 02/14/2024] [Indexed: 03/27/2024]
Abstract
BACKGROUND Oral corticosteroids are commonly used for acute preschool wheeze, although there is conflicting evidence of their benefit. We assessed the clinical efficacy of oral corticosteroids by means of a systematic review and individual participant data (IPD) meta-analysis. METHODS In this systematic review with IPD meta-analysis, we systematically searched eight databases (PubMed, Ovid Embase, CINAHLplus, CENTRAL, ClinicalTrials.gov, EudraCT, EU Clinical Trials Register, WHO Clinical Trials Registry) for randomised clinical trials published from Jan 1, 1994, to June 30, 2020, comparing oral corticosteroids with placebo in children aged 12 to 71 months with acute preschool wheeze in any setting based on the Population, Intervention, Comparison, Outcomes framework. We contacted principal investigators of eligible studies to obtain deidentified individual patient data. The primary outcome was change in wheezing severity score (WSS). A key secondary outcome length of hospital stay. We also calculated a pooled estimate of six commonly reported adverse events in the follow-up period of IPD datasets. One-stage and two-stage meta-analyses employing a random-effects model were used. This study is registered with PROSPERO, CRD42020193958. FINDINGS We identified 16 102 studies published between Jan 1, 1994, and June 30, 2020, from which there were 12 eligible trials after deduplication and screening. We obtained individual data from seven trials comprising 2172 children, with 1728 children in the eligible IPD age range; 853 (49·4%) received oral corticosteroids (544 [63·8%] male and 309 [36·2%] female) and 875 (50·6%) received placebo (583 [66·6%] male and 292 [33·4%] female). Compared with placebo, a greater change in WSS at 4 h was seen in the oral corticosteroids group (mean difference -0·31 [95% CI -0·38 to -0·24]; p=0·011) but not 12 h (-0·02 [-0·17 to 0·14]; p=0·68), with low heterogeneity between studies (I2=0%; τ2<0·001). Length of hospital stay was significantly reduced in the oral corticosteroids group (-3·18 h [-4·43 to -1·93]; p=0·0021; I2=0%; τ2<0·001). Subgroup analyses showed that this reduction was greatest in those with a history of wheezing or asthma (-4·54 h [-5·57 to -3·52]; pinteraction=0·0007). Adverse events were infrequently reported (four of seven datasets), but oral corticosteroids were associated with an increased risk of vomiting (odds ratio 2·27 [95% CI 0·87 to 5·88]; τ2<0·001). Most datasets (six of seven) had a low risk of bias. INTERPRETATION Oral corticosteroids reduce WSS at 4 h and length of hospital stay in children with acute preschool wheeze. In those with a history of previous wheeze or asthma, oral corticosteroids provide a potentially clinically relevant effect on length of hospital stay. FUNDING Asthma UK Centre for Applied Research.

Abstract
AIM Pre-school wheeze is a common hospital presentation in Australasia. The aim of this study was to describe the regional hospital presentation and cost of pre-school wheeze. METHODS Audit of children diagnosed with pre-school wheeze at two hospitals in Auckland, New Zealand from October 2017 to September 2019. Guideline adherence was determined. RESULTS One hundred and ninety-two children made 247 pre-school wheeze hospital presentations. Pre-school wheeze accounted for a larger proportion of acute hospital presentations for Māori versus non-Māori children (rate ratio 1.76, 95% confidence intervals 1.32-2.31). Hospital representations with pre-school wheeze occurred in 38/192 (20%) children. The proportion with a pre-school wheeze representation was larger for Māori than non-Māori (30% vs. 16%, P = 0.02). Pre-school wheeze event median length of stay increased as household deprivation increased (P = 0.01). Clinical severity of 247 pre-school wheeze episodes was mild (n = 64, 26%), moderate (n = 153, 62%) and severe (n = 30, 12%). Of 244 episodes, inhaled bronchodilators only were given for 149 (61%), oxygen for 54 (22%) and intravenous treatment for 41 (17%). Hospital guideline use was evident in 164/247 (66%) episodes. Neither clinical severity nor treatment intensity varied with child sex, age or ethnicity or household deprivation. The estimated median (interquartile range) direct medical costs of each pre-school wheeze episode were NZ$1279 (NZ$774-2158). CONCLUSIONS In Auckland, pre-school wheeze accounts for a larger proportion of acute hospital presentations for Māori compared with non-Māori and Māori children have increased odds of pre-school wheeze readmissions. Length of hospital stay for pre-school wheeze episodes increased with household deprivation. In this audit pre-school wheeze guideline adherence was poor.

Abstract
INTRODUCTION Wheezing disorders in preschool children are common. Current treatment approaches assume all preschool wheezers are the same and will respond to a short course of oral corticosteroids (OCS) during acute attacks and subsequent maintenance inhaled corticosteroids (ICS) to prevent future attacks. But we have increasing evidence showing preschool wheezing disorders are markedly heterogeneous and the response to corticosteroids either during acute attacks or as maintenance therapy can be variable between patients and is determined by disease severity and underlying pathological phenotype. AREAS COVERED The aim of this review is to discuss recent evidence which will help to explain a few critical pathophysiological concepts that are often misunderstood, thus helping to demystify the controversies that often surround preschool wheezing disorders and can contribute to ineffective management. EXPERT OPINION Preschool wheezing disorders are distinct from school-age allergic asthma. There is little evidence to support the use of oral corticosteroids for acute attacks. A staged approach to confirm the diagnosis, and objective tests to determine the pathological phenotype of preschool wheeze is essential prior to initiating maintenance therapy to control symptoms and prevent attacks in children with recurrent preschool wheeze.

Abstract
Preschool wheezing should be considered an umbrella term for distinctive diseases with different observable and measurable phenotypes. Despite many efforts, there is a large gap in knowledge regarding management of preschool wheezing. In order to fill this lack of knowledge, the aim of these guidelines was to define management of wheezing disorders in preschool children (aged up to 5 years). A multidisciplinary panel of experts of the Emilia-Romagna Region, Italy, addressed twelve different key questions regarding the management of preschool wheezing. Clinical questions have been formulated by the expert panel using the PICO format (Patients, Intervention, Comparison, Outcomes) and systematic reviews have been conducted on PubMed to answer these specific questions, with the aim of formulating recommendations. The GRADE approach has been used for each selected paper, to assess the quality of the evidence and the degree of recommendations. These guidelines represent, in our opinion, the most complete and up-to-date collection of recommendations on preschool wheezing to guide pediatricians in the management of their patients, standardizing approaches. Undoubtedly, more research is needed to find objective biomarkers and understand underlying mechanisms to assess phenotype and endotype and to personalize targeted treatment.

Abstract
BACKGROUND Oral corticosteroids are often used to treat acute asthma or asthma caused by respiratory tract infection in adult patients, but the effect of oral corticosteroids in young children is still controversial. We conducted a meta-analysis of controlled clinical studies to examine the effect of oral corticosteroids in children with respiratory diseases. METHODS Embase, PubMed, Web of Science, Ovid, ClinicalTrials.org from January 2000 to August 2021 were searched for randomized control trials related to the treatment of pediatric respiratory diseases with corticosteroid drugs using the keywords "corticosteroids" and "acute respiratory diseases". After screening the articles, Revman 5.4 software was used for the analysis. RESULTS A total of 8 articles (comprising 2,327 patients, 4 kinds of corticosteroids, and 3 types of pediatric respiratory disease) were included in the meta-analysis. The results showed that the length of hospital stay of patients in the experimental group treated with corticosteroids was shorter than that of patients in the control group [mean difference =-2.03, 95% confidence interval (CI): -2.91, -1.14; P<0.00001]. Further, the number and proportion of uncured patients after 3 days of treatment were lower in the experimental group than the control group [odds ratio (OR) =0.55, 95% CI: 0.42, 0.72; P<0.00001]. There were no differences in relation to adverse reactions (OR =0.57, 95% CI: 0.31, 1.07; P=0.08), and the readmission rate between the experimental and control groups (OR =0.94, 95% CI: 0.66, 1.34; P=0.75). DISCUSSION Corticosteroid use in the treatment of respiratory diseases in children can significantly shorten hospitalization time and increase the cure rate without increasing adverse reactions.
