ABSTRACT
<p><b>BACKGROUND</b>Evidence suggests that systemic inflammation may play an important role in the progression and morbidity of chronic obstructive pulmonary disease. It remains controversial whether inhaled corticosteroid in combination with a long-acting beta(2)-adrenoceptor agonist can attenuate systemic inflammation. We evaluated the effect of salmeterol/fluticasone propionate on circulating C-reactive protein level in stable chronic obstructive pulmonary disease patients.</p><p><b>METHODS</b>An open-label clinical trial was conducted to recruit 122 outpatients with stable moderate-to-severe chronic obstructive pulmonary disease from department of respiratory medicine in two teaching hospitals between June 2007 and March 2008. Patients were randomized into two groups (11) to receive either the combination of 50 microg salmeterol and 500 microg fluticasone twice daily (n = 61), or the combination of 206 microg albuterol and 36 microg ipratropium q.i.d (n = 61) over 6 months. Circulating C-reactive protein concentrations were measured before randomization and during the follow-up. The efficacy of treatment was also assessed by spirometry, as well as health status and dyspnea score at baseline and after 6-month treatment.</p><p><b>RESULTS</b>Baseline characteristics of two groups were similar. Compared with ipratropium/albuterol, the combination of salmeterol/fluticasone significantly reduced circulating level of C-reactive protein (-1.73 vs. 0.08 mg/L, respectively, P < 0.05) after 6-month treatment. Forced expiratory volume in one second (FEV(1)) and health status also improved significantly in salmeterol/fluticasone group compared with ipratropium/albuterol. Salmeterol/fluticasone treatment subjects who had a decrease of circulating C-reactive protein level had a significant improvement in FEV(1) and St George's Respiratory Questionnaire total scores compared with those who did not (185 vs. 83 ml and -5.71 vs. -1.79 units, respectively, both P < 0.01).</p><p><b>CONCLUSION</b>Salmeterol/fluticasone treatment reduced circulating C-reactive protein concentration in clinically stable moderate-to-severe chronic obstructive pulmonary disease patients after 6-month treatment.</p>
