Abstract

Aspergillus fumigatus is commonly found in cystic fibrosis (CF) airways. Our aim was to assess the relationship between A. fumigatus chronic colonization and lung function in CF patients. A case-control study of CF patients born from 1989 to 2002 was performed. Medical records were reviewed from the time of initial diagnosis until December 2013. Chronic colonization was defined as two or more positive sputum cultures in a given year. Each patient chronically colonized with A. fumigatus was matched with three control patients (never colonized by A. fumigatus) for age, sex, and year of birth (±3 years). A number of parameters were recorded and analyzed prospectively. The primary outcome measure was the difference in forced expiratory volume in 1 s (FEV1) in percent predicted between groups. Linear mixed models were used for longitudinal analyses to evaluate the relationship between A. fumigatus chronic colonization and lung function during a 7-year period and study the lung function 4 years before the time of enrollment (t0). Twenty patients had chronic colonization and were matched with 60 controls. A significant difference in lung function was detected throughout the 7-year period after adjustment for confounders (est = 8.66, p...Continue Reading

Aspergillosis (ASM)

Aspergillosis is the name given to a wide variety of diseases caused by infection by fungi of the genus Aspergillus. Aspergillosis occurs in chronic or acute forms which are clinically very distinct. Most cases of acute aspergillosis occur in patients with severely compromised immune systems. Chronic colonization or infection can cause complications in people with underlying respiratory illnesses. Discover the latest research on aspergillosis here.
