Lung volumes and the most common bacterial colonization in patients with allergic airways disease

الملخص EN

This study was aimed to investigate the relationship between bacterial colonization and lung function tests in allergic airways disease patients.

Two groups of individuals were included in this study ; 17 healthy subjects group and 21 patients with allergic airways disease group, which was further subdivided into two subgroups;8 smokers and 13 nonsmokers.

Lung function tests were estimated by using a micro medical lab spirometer.

Bacterial colonization was identified in the sputum sample of each individual.

The results showed significant declines in the lung function tests FEV1, FVC and FEV1 (2.74, 3.49 and 77.4) respectively (p < o.o5) for the patients with allergic airways disease .Bacterial colonization identification showed different type of bacterial isolates in the two studied groups.

The most common bacterial isolates of the patients group belong to Streptococcus pneumonia, Staphylococcus aureus and E coli.

There was no interaction between the lung volumes and bacterial colonization among the subjects colonized by different types of bacteria within the same group.
