Systemic inflammation and its response to treatment in patients with asthma

Abstract

BACKGROUND: Asthma is an obstructive airway disease characterized by airway inflammation. OBJECTIVE: To measure systemic inflammation in asthma patients, and to assess the effect of treatment on systemic inflammation. METHODS: In 30 newly diagnosed non-randomized adult asthma patients we measured systemic inflammation markers (serum high-sensitivity C-reactive protein, total leukocyte count, and erythrocyte sedimentation rate) before and after a 6-week standard treatment with inhaled steroids and inhaled β2 agonist. The comparison group comprised 20 healthy control subjects. All the subjects were non-smokers. RESULTS: The measured systemic inflammation markers were higher in the asthma patients: high-sensitivity C-reactive protein 4.8 ± 6.0 mg/dL vs 1.5 ± 1.4 mg/dL, P
