Aspergillus fumigatus infection was confirmed by tests to assess the titer of antibodies (Ac) specific to IgA, IgM, IgG, serum IgE-Aspergillus fumigatus concentration, galactomannan level. Lung function was assessed by spirometry with FVC, FEV1 ("Autospiro Pal", Japan).Results: The basic group included 15 CF patients (68,2%:95CI 45,1-86,1) with Aspergillus fumigatus infection and the control group-17 CF patients (31,8%:95CI 13,9-54,9 ). The average age of the children in the basic group was 12,2±1,06 years (7,1-18 years) and the average age of the children in the control group was 9,9±1,43 years (6-17 years); p> 0,05. The mean values of the Ac anti-Aspergillus fumigatus titer in this group were 1:415±52,9 (maximum titer 1:640, minimum 1:320, median 1:320, Mo 1:320).In CF patients with pulmonary aspergillosis FVC had lower values – 53,2±5,9% (maximum value 88%, minimum 26%, median 49%, Mo 26%) compared to children in the control group - 61,3±13,4% (maximum 98%, minimum 31%, median 59,5%, Mo 31%), statistical T=0,69, p <0,05. The obstructive disorders assessed by FEV1 in the patients in the study group were more expressed – 50,4±6,9% (maximum 88%, minimum 20%, median 44%, Mo 31%) compared to non-Aspergillus CF children - 61±14,1% (maximum 100%, minimum 31%, median 55%, Mo 31%), statistical T=0,81, p <0,05.Conclusion: Aspergillus fumigatus infection in children with CF has a severe impact on restrictive and obstructive respiratory function.FootnotesCite this article as: European Respiratory Journal 2021; 58: Suppl. 65, PA3377.This abstract was presented at the 2021 ERS International Congress, in session “Prediction of exacerbations in patients with COPD”.This is an ERS International Congress abstract.
