Respiratory system parameters in children with low severity cystic fibrosis: is there early involvement in relation to healthy peers?
ABSTRACT Objective: To compare and analyze pulmonary function and respiratory mechanics parameters between healthy children and children with cystic fibrosis. Methods: This cross-sectional analytical study included healthy children (HSG) and children with cystic fibrosis (CFG), aged 6–13 years, from teaching institutions and a reference center for cystic fibrosis in Florianópolis/SC, Brazil. The patients were paired by age and sex. Initially, an anthropometric evaluation was undertaken to pair the sample characteristics in both groups; the medical records of CFG were consulted for bacterial colonization, genotype, and disease severity (Schwachman-Doershuk Score — SDS) data. Spirometry and impulse oscillometry were used to assess pulmonary function. Results: In total, 110 children were included, 55 in each group. In the CFG group, 58.2% were classified as excellent by SDS, 49.1% showed the ΔF508 heterozygotic genotype, and 67.3% were colonized by some pathogens. Statistical analysis revealed significant differences between both groups (p<0.05) in most pulmonary function parameters and respiratory mechanics. Conclusions: Children with cystic fibrosis showed obstructive ventilatory disorders and compromised peripheral airways compared with healthy children. These findings reinforce the early changes in pulmonary function and mechanics associated with this disease.
期刊介绍:
The Revista Paulista de Pediatria publishes original contributions, case reports and review of clinical research with methodological approach in the areas of health and disease of neonates, infants, children and adolescents. The objective is to disseminate research with methodological quality on issues that comprise the health of children and adolescents. All articles are freely available online, via SciELO. Its abbreviated title is Rev. Paul. Pediatr., which should be used in bibliographies, footnotes and bibliographical references and strips.
