Prevalence of Comorbidities in Patients with Chronic Obstructive Pulmonary Disease

Background: Chronic obstructive pulmonary disease (COPD) is associated with many comorbidities, but the percentage of COPD patients who develop comorbidities has not been clearly defined. Objectives: We aimed to examine the relationship between COPD and comorbidities using information obtained from the Health Search Database (HSD) owned by the Italian College of General Practitioners (SIMG), which stores information on about 1.5% of the total Italian population served by general practitioners. Methods: We conducted a population-based retrospective study using information obtained from the HSD. The software system used codes all the diagnostic records using the 9th Revision of the International Classification of Diseases. Results: Compared to the non-COPD people, COPD patients were at increased risk for cardiovascular events [ischemic heart disease (6.9% in the general population vs. 13.6% in COPD patients), cardiac arrhythmia (6.6% in the general population vs. 15.9% in COPD patients), heart failure (2.0% in the general population vs. 7.9% in COPD patients), and other forms of heart disease (10.7% in the general population vs. 23.1% in COPD patients); with a higher impact of COPD in the elderly]; non-psychotic mental disorders, including depressive disorders (29.1% in the general population vs. 41.6% in COPD patients; with a higher impact of COPD on women aged <75 years); diabetes mellitus (10.5% in the general population vs. 18.7% in COPD patients); osteoporosis (10.8% in the general population vs. 14.8% in COPD patients), with a higher impact of COPD on women aged <75 years, and malignant pulmonary neoplasms (0.4% in the general population vs. 1.9% in COPD patients). Conclusions: Our results indicate that COPD is a risk factor for these comorbid conditions.

Combining triple therapy and pulmonary rehabilitation in patients with advanced COPD: A pilot study

BACKGROUND The synergistic interactions between pharmacotherapy and pulmonary rehabilitation has been provided, but it remains to be established whether this may also apply to more severe patients. OBJECTIVES We have examined whether tiotropium enhances the effects of exercise training in patients with advanced COPD (FEV(1)</=60% predicted, hypoxemia at rest corrected with oxygen supplementation, and limitations of physical activity). METHODS We enrolled 22 patients that were randomised to tiotropium 18mug or placebo inhalation capsules taken once daily. Both groups (11 patients in each group) underwent an in patient pulmonary rehabilitation program and were under regular treatment with salmeterol/fluticasone twice daily. Each rehabilitation session was held 5 days per week (3h/day) for a total of 4 weeks. RESULTS Compared to placebo, tiotropium had larger impact on pulmonary function (FEV(1)+0.164L, FVC +0.112L, RV -0.544L after tiotropium, FEV(1)+0.084L, FVC -0.039L, RV -0.036L after placebo). The addition of tiotropium allowed a longer distance walked in 6min (82.3m vs. 67.7m after placebo) and reduced dyspnoea (Borg score) (-0.4 vs. +0.18 after placebo) when compared with baseline (pre pulmonary rehabilitation program). The changes in SGRQ from baseline to the end of treatment were: total score -28.3U, activity -27.8U, impact -14.5U, and symptoms -33.4U in the placebo group; and total score -19.1U, activity -18.9U, impact -16.4U, and symptoms -33.8U in the tiotropium group. CONCLUSIONS Our study clearly indicates that there is an advantage in combining pulmonary rehabilitation with an aggressive drug therapy in more severe patients.

Rapid onset of bronchodilation with formoterol/beclomethasone Modulite and formoterol/budesonide Turbuhaler as compared to formoterol alone in patients with COPD.

In the present study, we examined whether there is a difference in the onset of bronchodilatation between formoterol/beclomethasone 12/200 μg Modulite and formoterol/budesonide 9/320 μg Turbuhaler in patients with COPD. We enrolled 28 patients with stable COPD. Both formoterol/beclomethasone and formoterol/budesonide elicited a larger mean FEV₁-AUC₀₋₁₅min than formoterol alone, whereas there was no significant difference between their FEV₁-AUC₀₋₁₅min. Also the change in FEV₁ 15 min after inhalation of formoterol/beclomethasone combination or formoterol/budesonide combination was greater than that induced by formoterol alone. This study confirms the rapid effect of the inhaled corticosteroid component when combined with formoterol and indicates that the onset of bronchodilation of formoterol/beclomethasone Modulite and formoterol/budesonide Turbuhaler are similar and greater than formoterol alone in patients with COPD.

BODE index and pulmonary rehabilitation in chronic respiratory failure.

To the Editors: We read with interest the article by Cote and Celli 1 regarding the beneficial effects induced by pulmonary rehabilitation (PR) on the BODE (body mass index (BMI), degree of airway obstruction, dyspnoea, exercise capacity) index (BI) in patients with chronic obstructive pulmonary disease (COPD). In an observational study, Cote and Celli 1 showed that the response to outpatient PR can be objectively measured using the BI, whose change provides information regarding ultimate survival, and that participation in a PR is associated with a decrease in the number of hospitalisations. This multidimensional 10-point scale has been previously shown to predict the death risk in COPD patients 2 …

Pulmonary rehabilitation following radical chemo-radiation in locally advanced non surgical NSCLC: Preliminary evidences

pulmonary rehabilitation (PR) has been fully included in the trategy for treatment of lung cancer [1]. Evidences from ranomised controlled trials (RCTs) are scarce and limited to the ost-surgical setting [2] but a systematic review on the topic as recently concluded that “(rehabilitative) interventions preperatively or post-cancer treatment are associated with positive enefits on exercise capacity, symptoms and some domains of RQoL” [3]. We have a long-standing interest in this approach [4–6] nd the positive results in our everyday clinical practice, based n extensive multidisciplinary cooperation, have prompted us to xplore its further application beyond the strictly “peri-surgical” etting. We have therefore offered to patients with locally advanced SCLC who are not suitable for surgical treatment an inpatient Pulonary Rehabilitation protocol (iPR), comprehensively described n [4] and summarised below. According to oncological guideines, these patients undergo concurrent chemo-radiation (CTRT) dministered with radical intent where pulmonary toxicity is one f the most important adverse effect limiting the delivered radition dose (and plausibly the overall cure rate). We report here ur preliminary findings, in a setting not matched with a control roup, on the feasibility and efficacy of this approach. Following nformed consent and communication to the local ethical comittee, according to national guidelines and regulations the iPR s routinely prescribed and performed on the basis of the pulonary functionality of patients. Following the chemo-radiation

Prulifloxacin in the treatment of acute exacerbations of COPD in cigarette smokers

Smoking is associated with an increased risk of respiratory tract infection in adults likely because components in the smoke might alter properties of the epithelial cell surface. In studies with smokers suffering from acute exacerbations of COPD (AECOPD), the most common bacterial pathogens found were mainly Haemophilus influenzae, but also Streptococcus pneumoniae, Staphylococcus aureus, and Moraxella catarrhalis. Therefore, antibiotics should be effective against such possible pathogens. Prulifloxacin has demonstrated in vitro activity against all these pathogens. We designed the present study to evaluate the efficacy of prulifloxacin in the treatment of AECOPD in cigarette smokers. We enrolled 61 consecutive smokers hospitalized or out-patients of either sex with symptoms and signs compatible with the usual diagnosis criteria for AECOPD. Haemophilus influenzae was the most common bacterial species isolated in the sputum (in 42.6% of the total sample), followed by S. pneumoniae (16.5%), S. aureus (14.7%), M. catarrhalis (11.5%), and others (14.7%). Prulifloxacin 600 mg was given orally once daily for 10 days. Clinical success was observed in 91.8% of patients (67.2% cured and 24.6% improved). Bacteriological eradication rate of H. influenzae was 100%. Persistent pathogens were S. pneumoniae (2 out of 10), S. aureus (1 out of 8), M. catarrhalis (1 out of 7), and P. aeruginosa (1 out of 3). This study seems to indicate that prulifloxacin is of particular value in the treatment of AECOPD in cigarette smokers.
