ABSTRACT
Baseline bronchial reactivity was studied in 36 patients with chronic obstructive lung disease (COLD) and 20 normal healthy controls using the inhalational histamine challenge test. Using a cut off PD20 dose of 0.195 mg of histamine, 83.3% patients of COLD demonstrated bronchial hyper-reactivity. Presence of bronchial reactivity correlated significantly with the baseline FEV1, FEF25-75 and the ratio FEV1/FVC (p = 0.0019, 0.00001 and 0.008) respectively. Thus, bronchial reactivity in subjects with COLD correlates most significantly with the maximum mid-expiratory flow rate (FEF25-75).
