- ItemBronchiolitis phenotypes identified by latent class analysis may influence the occurrence of respiratory sequelae(2021) Laura Petrarca; Raffaella Nenna; Greta Di Mattia; Antonella Frassanito; Jose A. Castro‐Rodriguez; Carlos E. Rodriguez Martinez; Enrica Mancino; Serena Arima; Carolina Scagnolari; Alessandra Pierangeli; Fabio MidullaBackground The heterogeneity of bronchiolitis may imply or reflect a different predisposition to respiratory sequelae. Objective Our aim was to investigate whether, among infants hospitalized with bronchiolitis, different clinical profiles extracted by latent class analysis (LCA) are associated with different risks of wheezing. Methods Over 15 consecutive epidemic seasons (2004-2019), we prospectively enrolled infants <1 year hospitalized for the first episode of bronchiolitis in a single tertiary hospital. A detailed clinical questionnaire was filled for each infant. LCA was applied to differentiate bronchiolitis phenotypes, and after hospital discharge, a phone interview was performed annually to record the presence of wheezing episodes. Adjusted multivariate regression analyses were run to investigate the risk of wheezing during 7 years follow-up according to clinical phenotypes. Results LCA performed on 1312 infants resulted in a three-class model. Profile 1 (65.5%): moderate bronchiolitis; Profile 2 (6.1%): severe bronchiolitis; and Profile 3(28.4%): bronchiolitis infants with high eosinophils blood count. At 1 year of follow up, about 50% of children presented wheezing in each profile. Compared to Profile 1, the adjusted odds ratio (OR) of having wheezing episodes was significantly higher in Profile 2 at 2, 3, and 4 years of follow-up. At 7 years, Profile 3 had an adjusted OR = 2.58, higher than Profile 2 (adjusted OR = 2.29). Conclusions LCA clearly identified a "moderate", "severe," and "high eosinophils blood count" bronchiolitis. During the first 4 years after bronchiolitis, the "severe" profile showed the higher risk of wheezing, but after 7 years this risk seems higher in the "high eosinophils blood count" group.
- ItemGenes, environment, and developmental timing: New insights from translational approaches to understand early origins of respiratory diseases(2021) Maria J. Gutierrez; Geovanny F. Perez; Jose L. Gomez; Carlos E. Rodriguez‐Martinez; Jose A. Castro‐Rodriguez; Gustavo NinoOver the past decade, "omics" approaches have advanced our understanding of the molecular programming of the airways in humans. Several studies have identified potential molecular mechanisms that contribute to early life epigenetic reprogramming, including DNA methylation, histone modifications, microRNAs, and the homeostasis of the respiratory mucosa (epithelial function and microbiota). Current evidence supports the notion that early infancy is characterized by heightened susceptibility to airway genetic reprogramming in response to the first exposures in life, some of which can have life-long consequences. Here, we summarize and analyze the latest insights from studies that support a novel epigenetic paradigm centered on human maturational and developmental programs including three cardinal elements: genes, environment, and developmental timing. The combination of these factors is likely responsible for the functional trajectory of the respiratory system at the molecular, functional, and clinical levels.
- ItemThe role of respiratory syncytial virus‐ and rhinovirus‐induced bronchiolitis in recurrent wheeze and asthma—A systematic review and meta‐analysis(2022) Heidi Makrinioti; Kohei Hasegawa; John Lakoumentas; Paraskevi Xepapadaki; Maria Tsolia; Jose A. Castro‐Rodriguez; Wojciech Feleszko; Tuomas Jartti; Sebastian L. Johnston; Andrew Bush; Vasiliki Papaevangelou; Carlos A. Camargo, Jr.; Nikolaos G. PapadopoulosIntroduction Respiratory syncytial virus (RSV) is the most common cause of bronchiolitis. RSV-induced bronchiolitis has been associated with preschool wheeze and asthma in cohort studies where the comparison groups consist of healthy infants. However, recent studies identify rhinovirus (RV)-induced bronchiolitis as a potentially stronger risk factor for recurrent wheeze and asthma. Aim This systematic review and meta-analysis aimed to compare the associations of RSV- and RV-induced bronchiolitis with the development of preschool wheeze and childhood asthma. Methods We performed a systematic search of the published literature in five databases by using a MeSH term-based algorithm. Cohort studies that enrolled infants with bronchiolitis were included. The primary outcomes were recurrent wheeze and asthma diagnosis. Wald risk ratios and odds ratios (ORs) were estimated, along with their 95% confidence intervals (CIs). Individual and summary ORs were visualized with forest plots. Results There were 38 studies included in the meta-analysis. Meta-analysis of eight studies that had data on the association between infant bronchiolitis and recurrent wheeze showed that the RV-bronchiolitis group were more likely to develop recurrent wheeze than the RSV-bronchiolitis group (OR 4.11; 95% CI 2.24-7.56). Similarly, meta-analysis of the nine studies that had data on asthma development showed that the RV-bronchiolitis group were more likely to develop asthma (OR 2.72; 95% CI 1.48-4.99). Conclusion This is the first meta-analysis that directly compares between-virus differences in the magnitude of virus-recurrent wheeze and virus-childhood asthma outcomes. RV-induced bronchiolitis was more strongly associated with the risk of developing wheeze and childhood asthma.
