Clinical Trial Summary

Chronic obstructive pulmonary disease (COPD) is a common disease that has a chronic and progressive course. Patients with COPD may have exacerbations one to four times in a year. Numbers of exacerbations are important because of increased morbidity and mortality and healthcare costs.

Systemic corticosteroids (SC) are recommended in the management of exacerbations of COPD as well as bronchodilator, oxygen and antibacterial treatment by all international guidelines. However, there are still some concerns about systemic corticosteroid use because COPD patients are older and relatively immobilized. In addition, exacerbation rate is significantly higher in a group of COPD patients, and these patients need higher amounts of SC in order to control of exacerbation. It results in some adverse effects such as osteoporosis and bone fractures, thinning of the skin, posterior subcapsular cataract formation, glucose intolerance and myopathy. Thus, this condition leads clinicians to seek alternative options. However, there are few studies showing that nebulized steroids (NS) are as effective as SC in exacerbations of COPD and the optimal NS dose is not certain.

The investigators aimed to determine the optimal NS dose and evaluate the efficacy and safety of NS compared with SC in the treatment of patients with COPD exacerbations requiring hospitalization.

Description:

Study Population One hundred twenty patients with moderate or severe COPD exacerbation who are older than 40-years-old, had a smoking history of at least 10-pack-years and requiring hospitalization were included in the study. COPD diagnosis was based on clinical evaluation as defined by the American Thoracic Society (ATS). The patients were excluded if they had a presence of asthma, allergic rhinitis, atopy or any systemic disease (such as diabetes mellitus or hypertension); were exposed to systemic corticosteroids in the preceding month; used more than 1,500 microg/d of inhaled beclomethasone equivalent; were admission to the intensive care unit (pH<7.30 and/or arterial partial pressure of carbon dioxide (PaCO2) > 70 mm Hg, and/or arterial partial pressure of oxygen (PaO2) < 50 mm Hg despite supplemental oxygen); if a specific cause for the exacerbation, such as pneumonia, pneumothorax, or heart failure, was diagnosed.

Study Design The study was as a randomized, double-blind, parallel design trial. The randomization order was determined using a computer-generated list of random numbers. Eligible patients were randomly allocated to one of the three treatment groups, that is, parenteral corticosteroid (PS), 4 mg nebulized budesonide (NB) or 8 mg NB. The efficacy of the study medications was assessed at hospitalization, 24 h, 48 h and before discharge. Patients were monitored during the hospitalization. Patients were withdrawn from the study if they required intubation and managed in intensive care unit.

Treatments Treatment in the PS group consisted of methylprednisolone 40 mg (intravenous ampoule); treatment in the NB groups consisted of nebulized budesonide suspension (Pulmicort nebuampul® 0.5 mg/ml; Astra-Zeneca Pharmaceutical Production) for 10 days. Budesonide were given as 2 mg twice daily or 4 mg twice daily; methylprednisolone were given once daily intravenously.

Nebulization procedures were performed by jet nebulizer (Porta Neb® Ventstream® 1803; Medic-Aid) with 80% of output of less than 5 micron. Patients received standard treatment with a nebulized ß-agonist (salbutamol 3.01 mg) and anticholinergic (ipratropium bromide 0.5 mg) combination every 6 hours, intravenous aminophylline (0.5 mg/kg/h) and oral or intravenous antibacterial at the discretion of the attending physician. Supplementary oxygen therapy was used to maintain oxygen saturation (SaO2) >90%.

Measurements Patients were assessed every 12 h during the acute phase (from H0 to H48), and at hospital discharge. Arterial blood samples were taken at baseline, 24, 48 h and before discharge for the determination of PaO2, PaCO2, and pH, regardless of whether the patient was on room air or on supplementary oxygen. Spirometry (Sensor Medics, Vmax22) was carried out before and 15 to 20 min after bronchodilator nebulization (ß2-agonist and ipratropium bromide) according to ATS standards. Dyspnea was assessed according to the modified Borg scale. Complete blood cell counts were obtained at entry, and blood glucose, sodium, potassium were measured at H0 and H48.

Endpoints The primary endpoint was to assess treatment efficacy by the change of arterial blood gases from H0 to H24, H48 and before discharge. Secondary endpoints included the changes in FEV1 (forced expiratory volume in 1 second), dyspnea score, duration of hospitalization, and occurrence of adverse events. An adverse event was defined as any medical event reported by the attending physician and events resulting in treatment change, discontinuation study medication or prolonged of hospitalization.
