Abstract
Preschool children with wheezing disorders pose diagnostic and therapeutic challenges and consume substantial healthcare resources. Peripheral eosinophil blood count (EBC) has been proposed as a potential indicator for future asthma development. This review by the European Academy of Allergy and Clinical Immunology (EAACI) Preschool Wheeze Task Force aimed to provide systematic evidence for the association between increased EBC and the risk of future asthma, as well as to identify potential cutoff values. In February 2023, a search of PubMed, EMBASE, and Cochrane Library databases was conducted to identify studies comparing EBCs in preschool children with wheezing who continued to wheeze later in life and those who did not. Included observational studies focused on children aged <6 years with a wheezing disorder, assessment of their EBCs, and subsequent asthma status. No language or publication date restrictions were applied. Among the initial 3394 studies screened, 10 were included in the final analysis, involving 1225 patients. The data from these studies demonstrated that high EBC in preschool children with wheezing is associated with future asthma development, with odds ratios of 1.90 (95% CI: 0.45-7.98, p = .38), 2.87 (95% CI: 1.38-5.95, p < .05), and 3.38 (95% CI: 1.72-6.64, p < .05) for cutoff values in the <300, 300-449, and ≥450 cells/μL ranges, respectively. Defining a specific cutoff point for an elevated EBC lacks consistency, but children with EBC >300 cells/μL are at increased risk of asthma. However, further research is needed due to the limitations of the included studies. Future investigations are necessary to fully elucidate the discussed association.

Association of p-phenylenediamine exposure with alterations of pulmonary function, pruritus and health-related quality of life in hair dye factory workers: a cross-sectional study. Sci Rep 2023; 13:2623. [PMID: 36788348 PMCID: PMC9929233 DOI: 10.1038/s41598-023-29721-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2022] [Accepted: 02/09/2023] [Indexed: 02/16/2023] Open
Abstract
P-Phenylenediamine (PPD) is a common component of hair dye, which can cause skin contact allergy and asthma with impaired pulmonary function. However, the adverse effects of occupational exposure to different dose PPD was rarely mentioned. We recruited 124 workers from a hair dye factory to explore the association of occupational PPD exposure on pulmonary function, pruritus and health related quality of life (HRQL). We categorized exposure to PPD into 3 levels: lower exposure group (< 0.00001 mg/m3); middle exposure group (0.00001-0.00033 mg/m3); higher exposure group (0.00033-0.047 mg/m3). The HRQL and subjective pruritus of the workers were assessed by the short form 36 health survey (SF-36) and Visual analogue scale (VAS) of pruritus, respectively. In the high PPD-exposed group, the percentage of FEV1 (FEV1%) was lower in higher exposure group compared with lower exposure group. The FEV1/FVC was also lower in comparison to the higher exposure and middle exposure groups (p < 0.05). PPD levels were negatively correlated with vitality and mental health (p < 0.01). The structural equation model showed the positive effects of PPD on VAS level (β = 0.213, p < 0.001), and indicated partly negtive effects of PPD on total score of SF-36 (β = - 0.465, p = 0.002), respectively. Our results indicate that occupational exposure to PPD might be associated with pulmonary function impairment, poor HRQL, and subjective pruritus of the workers.

J Pediatr (Rio J) 2022; 98:490-495.

Abstract
OBJECTIVE To evaluate the relationship between asthma control, family income and family costs of asthma in a population of children-adolescents; to detail the family costs of asthma in this age range; and to compare asthma costs for the families of children-adolescents and adults. METHODS The authors invited asthmatic subjects who attended a scheduled spirometry test at the Jundiaí School of Medicine (FMJ). The FMJ performs all spirometry tests requested by staff physicians who serve at the public healthcare system in the municipality. Volunteers responded to the ACQ, the Asthma Family Costs Questionnaire and underwent a spirometry test. RESULTS The authors included 342 children-adolescents. Families of children-adolescents taking maintenance therapy and families of those reporting uncontrolled asthma symptoms were more likely to report any expenditure with asthma during the preceding month. In this age range, the smallest expenditures were on diagnostic tests and medical consultations, while home expenditures to avoid asthma triggers were the highest ones. As compared to adults' families, the children and adolescents families reported a greater proportion of income committed with asthma. Expenditures with transportation to healthcare facilities for asthma care were greater in the families of children-adolescents as compared to the values reported by the adults' families; in contrast, loss of income due to asthma was smaller in the families of children-adolescents. CONCLUSIONS Children-adolescents' asthma affects the household economy. The authors believe researchers should assess this outcome when designing studies about asthma. Finally, the study's data support the necessity of public policies in low-resource communities to minimize the economic impact of children and adolescents' asthma.

Abstract
Advances in the understanding that severe asthma is a complex and heterogeneous disease and in the knowledge of the pathophysiology of asthma, with the identification of different phenotypes and endotypes, have allowed new approaches for the diagnosis and characterization of the disease and have resulted in relevant changes in pharmacological management. In this context, the definition of severe asthma has been established, being differentiated from difficult-to-control asthma. These recommendations address this topic and review advances in phenotyping, use of biomarkers, and new treatments for severe asthma. Emphasis is given to topics regarding personalized management of the patient and selection of biologicals, as well as the importance of evaluating the response to treatment. These recommendations apply to adults and children with severe asthma and are targeted at physicians involved in asthma treatment. A panel of 17 Brazilian pulmonologists was invited to review recent evidence on the diagnosis and management of severe asthma, adapting it to the Brazilian reality. Each of the experts was responsible for reviewing a topic or question relevant to the topic. In a second phase, four experts discussed and structured the texts produced, and, in the last phase, all experts reviewed and approved the present manuscript and its recommendations.
