This cross-sectional study included fifty asthmatic children in the age group of 6-16 years. Asthmatic patients were classified according to their complete blood count and iron profile into 2 groups: group 1; asthmatic children without iron deficiency anemia (IDA), group 2; asthmatic children with IDA. All patients underwent full history taking, clinical examination, laboratory investigations, asthma control test, and pulmonary function tests.
Pulmonary function testing was performed using standardized spirometry. Lung function was measured by forced expiratory volume in one second (FEV1), forced vital capacity (FVC), FEV1/FVC, and maximal mid-expiratory flow (MMEF 25-75%) of FVC. both patients' groups are compared.
