Withdrawal of corticosteroid is associated with a deterioration of health status in COPD. In this study the aim was to determine whether high dose inhaled corticosteroid improves quality of life in patients with COPD.
                In total, 38 male patients with moderate COPD were included in the study. Baseline quality of life scores were determined using a Turkish version of the St George's Respiratory Questionnaire (SGRQ). Patients were randomly divided into two groups. Group 1 consisted of 20 patients who received existing bronchodilator therapy plus inhaled corticosteroid (800 micro g budesonide) for 12 weeks, while 18 patients in group 2 received bronchodilator and placebo. The SGRQ was repeated after the treatment period.
                All patients were male and mean age was 67 +/- 8.2 years. Symptom, activity, impact, and total scores were assessed and a difference of four units with treatment was considered to be clinically significant. Total score and activity score were decreased by six units and eight units, respectively, in the placebo group while symptom and impact scores did not change significantly. Total scores and the three component scores improved significantly in the corticosteroid group compared to the placebo group (Deltatotal score: -22 in corticosteroid group, -6 in placebo group, P < 0.01).
                Inhaled corticosteroid improved quality of life scores in patients with COPD, without significant improvement in airflow obstruction parameters. Since improvement of health status is one of the important aims in COPD treatment, use of inhaled corticosteroids should be considered from this perspective. A significant minority of patients with COPD have favourable response to corticosteroid treatment. In addition, the benefit of corticosteroid treatment may be outweighed by the side-effects. Long-term administration of inhaled steroids is a safe means of treatment. However, only a few studies have addressed the role of inhaled steroids in patients with COPD, with conflicting results.
                Forty-four patients with stable COPD were defined as 'responders to bronchodilators' (increase in FEV1 > or = 20% following administration of beta 2-agonist) (group A), and 124 as 'non-responders to bronchodilators' (group B). All patients were randomized to receive a 6-week course of either a daily dose of 800 micrograms of inhaled budesonide or placebo, separated by 4 weeks when no medication was taken; were randomized again to receive a 6-week course of either 1600 micrograms day-1 of inhaled budesonide, or 800 micrograms day-1 of inhaled budesonide plus placebo; and were randomized once again to receive a 6-week course of either 40 mg day-1 of prednisone or placebo. All stages were performed in a double-blind cross-over design.
                Following administration of 800 micrograms day-1 of inhaled budesonide, there was an increase in the mean FEV1 from 1.40 +/- 0.20 to 1.92 +/- 0.22 L (P < 0.001) and a significant decrease in inhaled beta 2 agonist consumption in group A. These changes remained almost stable during the increased dose of inhaled budesonide or during prednisone treatment. The mean FEV1 did not change during the placebo period, or in group B in either treatments.
                Treatment with inhaled steroids improved spirometry data and inhaled beta 2-agonist consumption in about one-quarter of patients with stable COPD, and this rate increased to about three-quarters in patients who responded to beta 2-agonist inhalation. There was no additional benefit in using a higher dose of inhaled budesonide or prednisone. Combination therapy with corticosteroid and long-acting β(2)-agonists (LABA) in a single inhaler is associated with superior effects on airway function and exercise performance in COPD compared with LABA monotherapy. The physiological effects of adding inhaled corticosteroid monotherapy to maintenance bronchodilator therapy (long-acting anticholinergics and LABA singly or in combination) in COPD are unknown.
                This was a randomized, double-blind, placebo-controlled, crossover study (NCT00387036) to compare the effects of inhaled fluticasone propionate 500 μg (FP500) twice-daily and placebo (PLA) on airway function during rest and exercise, measured during constant work rate cycle exercise at 75% of maximum incremental cycle work rate, in 17 patients with COPD (FEV(1) ≤ 70% predicted).
                After treatment with FP500 compared to PLA, there were significant increases in post-dose measurements of FEV(1) (+115 mL, P = 0.006) and the FEV(1)/FVC ratio (+2.5%, P = 0.017), along with decreases in plethysmographic residual volume (-0.32L; P = 0.031), functional residual capacity (-0.30L, P = 0.033), and total lung capacity (-0.30L, P = 0.027) but no changes in vital capacity or inspiratory capacity (IC). Post-treatment comparisons demonstrated a significant improvement in endurance time by 188 ± 362 s with FP500 (P = 0.047) with no concomitant increase in dyspnea intensity. End-inspiratory and end-expiratory lung volumes were reduced at rest and throughout exercise with FP500 compared with PLA (P < 0.05).
                Inhaled FP500 monotherapy was associated with consistent and clinically important improvements in FEV(1), static lung volumes, dynamic operating lung volumes, and exercise endurance when added to established maintenance long-acting bronchodilator therapy in patients with moderate to severe COPD.

It remains unclear whether inhaled corticosteroids can produce the maximum benefits of corticosteroids in patients with chronic obstructive pulmonary disease (COPD). To assess the additive effects of 30 mg/day prednisolone to high-dose, inhaled beclomethasone dipropionate (BDP), we conducted a randomised double-blind, placebo-controlled cross-over trial. The study population consisted of 21 men with stable COPD. The mean age of the patients was 69.1 +/- 6.8 years, and FEV(1)was 0.86 +/- 0.28 l. Seventeen out of the 21 patients (81%) were considered susceptible to steroids in a previous trial (FEV(1)increased at least 15% from baseline after receiving 14 days of 30 mg/day prednisolone). All of the patients had been on 1600 microg/day BDP for more than 3 months. Spirometry was performed before the entry, and at the end of 3-week placebo and prednisolone periods. The peak expiratory flow (PEF), symptoms, and Guyatt's Chronic Respiratory Disease Questionnaire (CRQ) as a disease specific health-related quality of life over the last seven days of each period were also evaluated. Although a marginal increase in PEF was found during the prednisolone period, no significant differences in FEV(1), FVC, symptoms or CRQ scores were observed between the two treatment periods. We conclude that the therapeutic effects of steroid therapy may be achieved by the long-term use of high-dose, inhaled corticosteroid in some patients with stable COPD.
                Copyright 2000 Academic Press. Chronic obstructive pulmonary disease is characterized by progressive airflow limitation and pulmonary inflammation. Inhaled corticosteroids (ICS) have been shown to be effective in the reduction of the number of exacerbations and the rate of deterioration in health status in patients with more advanced chronic obstructive pulmonary disease (COPD). Therefore current international guidelines recommend ICS for patients with severe COPD (FEV1 < 50%) with at least one exacerbation within the last year. We determined the short-term effect of the inhaled corticosteroid beclomethasone in HFA 134 formulation (Ventolair) on Health related Quality of Life (HRQOL), pulmonary function and the release of the cytokines Interleukin-10 (IL-10), Granulocyte-Macrophage Colony-stimulating Factor (GM-CSF), Interferon-gamma (IFN-gamma) and Macrophage Inflammatory Protein-1alpha (MIP-1alpha) from peripheral blood monocytes of patients with COPD (n = 11) in a 12 week double blind cross over placebo-controlled study. Baseline lung function and the St. George Respiratory Questionnaire (SGRQ) were performed at the start and the end of each treatment phase. Monocytes were separated from blood at the end of each treatment phase. The treatment with Ventolair) resulted in an increase of PEF from 4.92 to 5.53 l/s and a decrease of RV% TLC (% predicted) values from 144.52 to 131.36. Inhaled HFA beclomethasone did not affect the cytokine release of IL-10, IFN-gamma, GM-CSF and MIP-1alpha. All cytokines were measured using commercially available Enzyme Linked Immun Sorbent Assay (ELISA) kits. The symptom score of the St. George Respiratory Questionnaire significantly decreased from 55.12 to 47.77 units in the active period compared to the placebo period after the treatment with HFA beclomethasone. The present study shows that a short-term treatment with inhaled steroid beclomethasone in fine particle HFA formulation decreases the hyperinflation and improves the PEF and the COPD symptoms. Recent studies suggested that administration of corticosteroids may improve clinical outcomes in patients with severe pneumonia.
                The aim of this study was to assess the effectiveness of corticosteroids as an adjunctive therapy in community-acquired pneumonia (CAP) requiring hospitalization.
                An open label, prospective, randomized control study was conducted from September 2003 to February 2004 in a community general hospital in Japan.
                Thirty-one adult CAP patients who required hospitalization were enrolled.
                Fifteen patients received 40 mg of prednisolone intravenously for 3 days (steroid group). Sixteen patients did not receive prednisolone (control group). Both groups were also evaluated for their adrenal function. The primary endpoint was length of hospital stay. Secondary endpoints were duration of intravenous (IV) antibiotics and time required to stabilize vital signs. Both groups demonstrated similar baseline characteristics and length of hospital stay, and yet a shorter duration of IV antibiotics was observed in the steroid group (p < 0.05). In addition, vital signs were stabilized earlier in the steroid group (p < 0.05). These differences were more prominent in the moderate-severe subgroup but not as significant in the mild-moderate subgroup. The prevalence of relative adrenal insufficiency (RAI) in both groups was high (43%), yet there was no difference in baseline characteristics between patients, with or without RAI. In multiple regression models, RAI seemed to have no influence on clinical courses.
                In moderate-severe CAP, administration of corticosteroids promotes resolution of clinical symptoms and reduces the duration of intravenous antibiotic therapy. Despite absence of clear proof of efficacy, the use of inhaled corticosteroids (ICS) is widespread in cystic fibrosis (CF) patients. Therefore, the effect of ICS on lung function and other clinical variables was studied in 27 prepubertal CF children with mild to moderate lung disease. In a prospective double-blind case-controlled study, fluticasone propionate 500 microg or placebo were administered twice daily during 12 months. The mean (standard error of the mean, SEM) patient age was 8.2 (0.6) years in the placebo group and 9.0 (0.5) years in the fluticasone group. The mean (SEM) forced expiratory volume in 1 s (FEV(1)) was 91% (4%) in the placebo group and 86% (4%) in the fluticasone group. There was no statistically significant difference in the evolution of lung function and the number of respiratory exacerbations between groups. However, longitudinal growth in fluticasone patients was significantly slower than in placebo patients: 3.96 (0.29) cm versus 5.49 (0.38) cm [p<0.005, analysis of variance (ANOVA)] over the 12-month study duration. This resulted in a significant change in height standard deviation score (SDS) of -0.38 (0.09) in the fluticasone group versus -0.01 (0.07) in the placebo group (p<0.003, ANOVA). No catch-up growth was noted 1-2 years after discontinuation of inhaled steroids. The use of high-dose ICS in CF patients with mild lung disease may lead to persistent growth impairment. Inhaled corticosteroids are widely prescribed for the treatment of stable chronic obstructive pulmonary disease (COPD), despite lack of proven efficacy. Because COPD involves airway inflammation and probable protease-antiprotease imbalance, we examined the effect of high dose fluticasone propionate on markers of activity of both pathogenetic mechanisms. Thirteen patients with COPD were treated with fluticasone propionate (500 microg twice a day) for 4 wk, delivered via MDI and spacer, in a double-blind crossover study. There was no clinical benefit in terms of lung function or symptom scores, and induced sputum inflammatory cells, percentage neutrophils, and IL-8 levels were unchanged. Sputum supernatant elastase activity, matrix metalloproteinase (MMP)-1, MMP-9, and the antiproteases secretory leukoprotease inhibitor (SLPI) and tissue inhibitor of metalloproteinase (TIMP)-1 were similarly unaffected by treatment. These results add to previous evidence that inhaled steroids have no anti-inflammatory action in stable COPD. Furthermore, inhaled steroids do not appear to redress the protease-antiprotease imbalance that is thought to be important in the pathogenesis of airway obstruction. Early treatment with inhaled corticosteroids may prevent progression of irreversible obstruction in COPD, especially in patients with bronchial hyperresponsiveness. We investigated the clinical effects of early introduction of inhaled steroids in subjects showing early signs and symptoms of COPD without a prior clinical diagnosis.
                Study subjects were detected in a general population screening and monitoring program. Those with a moderately accelerated annual FEV1 decline and persistent respiratory symptoms were invited to participate in a 2-year randomized controlled trial comparing fluticasone propionate DPI 250 microg b.i.d. with placebo. Pre- and post-bronchodilator (BD) FEV1, PC20 histamine, functional status (COOP/WONCA charts) and occurrence of exacerbations were periodically assessed. Subjects recorded respiratory symptoms. Post-BD FEV1 decline served as the main outcome. Multivariable repeated measurements analysis techniques were applied.
                48 subjects were randomized (24 fluticasone, 24 placebo). After 3 months, the post-BD FEV1 had increased with 125 ml (SE = 68, P = 0.075) and the pre-BD FEV1 with 174 ml (SE 90, P = 0.059) in the fluticasone relative to the placebo group. The subsequent post-BD and pre-BD FEV1 decline were not beneficially modified by fluticasone treatment. There were no statistically significant differences in respiratory symptoms, functional status, or exacerbations favoring fluticasone. Subgroup analysis indicated that the presence of bronchial hyperresponsiveness modified the initial FEV1 response on fluticasone, but not the subsequent annual FEV1 decline.
                Early initiation of inhaled steroid treatment does not seem to affect the progressive deterioration of lung function or other respiratory health outcomes in subjects with early signs and symptoms of COPD. In subjects at risk for, or in an early stage of COPD, long-term inhaled steroid treatment should not be based on a single spirometric evaluation after 3 months.
Combination ICS and LABA significantly reduces morbidity and mortality in COPD when compared with monocomponent steroid. Adverse events were not significantly different between treatments, although evidence from other sources indicates that inhaled corticosteroids are associated with increased risk of pneumonia. Assessment of BDF in larger, long-term trials is required. Dose response data would provide valuable evidence on whether efficacy and safety outcomes are affected by different steroid loads.
