Methods: Respiratory symptoms were assessed by a pulmonology physician (n=117). The FeNo was measured by NIOX MINO device (Aerocrine AB, Solna, Sweden). Lung function was examined by a portable spirometer and airway hyper-resposiveness. Asthma Control Questionnaire (ACQ), blood eosinophils were assessed at the same time.
Results: Respiratory symptoms were cough (100%), dyspnea (88%), wheezing at the physical exam (56%). Lower FEV1 (p<0.0001) and higher FeNO values (P=0.001) were observed in Afghanistan. Between blood eosinophil counts and FeNO did not show association.
Conclusions: This is the first study was performed in Afghanistan people. Respiratory symptoms and FeNo had association in Afghanistan. In future more subjects enroll and environmental factor are needed.
