The age of asthmatic patients ranged from 16-70 years (mean 42±19 years). The asthmatic patient’s femalemale ratio was 1.8. Mild asthma was the most common severity group (N=18, 43%) followed by moderate asthma (N=14, 33%) then severe asthma (N=10, 24%). Abnormal sputumeosinophilia (≥3%) was detected in 90% of severe asthma (N=9) compared to 36% in moderate asthma (N=5) and 5.6% in mild asthma (N=1). There was significant statistical association between asthma severity and sputumeosinophilia (p=0.00004). The association between asthma severity and total serumIgE levels was highly significant (p<0.0000) with levels of total serumIgE increasing as the severity of asthma increases.
Conclusions:
Severe asthma is the least common severity group in this study. Both abnormal sputumeosinophilia and total serumIgE levels are associated with the severity of asthma.
