| خلاصه مقاله | Background:
Idiopathic bronchiectasis is an irreversible abnormal dilation of proximal subsegmental bronchi. The aim was to survey CFTR gene variants in pediatric idiopathic Bronchiectasis.
Methods:
All children with idiopathic bronchiectasis confirmed and admitted to Tabriz Children’s Hospital, Iran were surveyed from 2019 to 2020. Demographic and clinical information was gathered by medical records and clinical examination and CFTR variants were investigated by liquid chromatography, direct sequencing, and multiple probe ligations tests. Then children were allocated into two groups based on CFTR variants when CF-causing mutations of varying clinical consequence variants were related to group 1, and polymorphisms related to group 2 to compare in terms of demographic, clinical, and para-clinical findings. Descriptive statistics, Chi-square Tests, and independent samples t-test were used to analyze the data using SPSS software version 22.0.
Results:
Out of 21 patients, 10 (47.6%) children were males with a mean age of 9.75 years. Five clinically significant CFTR-related gene variants were identified (group 1). Other patients either had only a single polymorphism or no variants related to CFTR (group 2). Age, FEV1, and sweat tests were lower in group 1 than in group 2.
Conclusion:
In this study, the CFTR variants in heterozygote types in pediatric Diffuse Bronchiectasis with a
normal or borderline sweat test. Therefore, it is necessary to determine whether DB is a part of CFTR Related Diseases failing to meet the diagnostic criteria of Cystic fibrosis or a disease independent of
Cystic fibrosis. |
