The level of (IL-1Beta) was related to the stage of
the disease as there was a significant increase in (IL-1Beta)
level with increasing severity of COPD; very severe COPD
cases have a higher level of (IL-1Beta) than severe and moderate
cases, (IL-1Beta) was also raised in severe cases than moderate
cases and the difference between them was highly
statistically significant (p < 0.01) (Table 7).
This is matched with [1], who reported that COPD results
from airway inflammation involving multiple inflammatory
mediators and tissue damage.
