Real-life prospective study on asthma control in Italy: Cross-sectional phase results

OBJECTIVES To estimate the prevalence of partly controlled and uncontrolled asthmatic patients, to evaluate quality of life and healthcare resource consumption. METHODS Cross-sectional phase followed by a 12-month prospective phase. Asthma Control Test and the EQ-5D were used. RESULTS 2853 adult patients recruited in 56 Hospital Respiratory Units in Italy were evaluated: 64.4% had controlled asthma, 15.8% partly controlled asthma and 19.8% were uncontrolled. The mean (SD) EQ-5D score was 0.86 (0.17) in controlled, 0.75 (0.20) in partly controlled and 0.69 (0.23) in uncontrolled patients (p<0.001 between groups). The number of patients requiring hospitalization or emergency room visits was lower in controlled (1.8% and 1.6%, respectively) than in partly controlled (5.1% and 11.5%) and uncontrolled (6.4% and 18.6%). A combination of an inhaled corticosteroid and a long-acting beta-2 agonist was the reported therapy by 56.0% of patients, with the rate of controlled asthma and improved quality of life being higher in patients on extrafine beclomethasone/formoterol compared to budesonide/formoterol (p<0.05) and fluticasone/salmeterol (p<0.05 for quality of life). CONCLUSIONS Asthma control is achieved in a good proportion of Italian patients. Differences may be detected in a real-life setting in favor of extrafine beclomethasone/formoterol combination.

1-year prospective real life monitoring of asthma control and quality of life in Italy

ObjectivesThe study aimed at prospectively evaluating the evolution of asthma control in Italy, to evaluate the reasons for lack of asthma control, perceived quality of life (QoL) and association with level of asthma control, the impact of pharmacological treatment, the number of exacerbations and the healthcare resource consumption.MethodsPRISMA (PRospectIve Study on asthMA control) was an observational study performed in asthmatic patients including a cross-sectional phase and a 12-month prospective phase. Asthma control was assessed with the Asthma Control Test™ (ACT) and QoL was evaluated with EuroQoL-5D questionnaire filled in and collected during 5 clinic visits together with all the other data.ResultsThe prospective phase included 1017 patients with uncontrolled (55.7%) or partly controlled asthma (44.3%). Out of the 739 patients evaluable after 12 months, 22.2% achieved full asthma control (ACT score = 25) and 58.7% reached a good control (ACT score: 20–24). The improvement in asthma control was associated with improved QoL and reduced hospital visits. The main reasons for lack of asthma control were comorbidities, continued exposure to irritants/triggers and poor adherence to therapy. The frequency of exacerbations was lower in patients with controlled asthma.A fixed combination therapy with an inhaled corticosteroid and a long-acting β2 agonist was reported by 77.0% of patients. A better asthma control and improved QoL were achieved with extrafine beclomethasone/formoterol compared to either budesonide/formoterol or fluticasone/salmeterol.ConclusionsAn improvement in asthma control and QoL can be achieved during a 1-year monitoring in a real life setting. Extrafine beclomethasone/formoterol was associated with significant benefit in terms of asthma control and QoL compared to large-particles combinations.ClinicalTrials.gov number NCT01110460.

Effect of the selective 5-HT2 antagonist ketanserin on adenosme-mduced bronchoconstriction in asthmatic subjects

In eight asthmatic subjects a randomized, double-blind, placebo controlled study was performed to investigate the effect of inhaled ketanserin, a 5-HT2 receptor blocking agent, in a dose of 10 mg given 30 min before test, on adenosine-induced bronchospasm. The protective effect of ketanserin was significant in all patients, even though it altered basal bronchomotor tone in only two subjects. On the contrary, ketanserin did not inhibit histamine-induced bronchoconstriction in four of these eight asthmatics, even though it modified sensitivity and reactivity in one of them. The results suggest that ketanserin influence on adenosine bronchial reactivity and sensitivity was not due to the bronchodilator effect of ketanserin itself or to its antihistaminic activity. We have no certain explanation for the inhibition of adenosine-induced bronchoconstriction elicited by ketanserin. It is possible that 5-HT may play, at least in part, a role as mediator of adenosine-induced bronchoconstriction.

Quality standards for the management of bronchiectasis in Italy: A national audit

Although historically considered a neglected disease, bronchiectasis has become a disease of renewed interest over recent decades in light of an increase in prevalence and a substantial burden on healthcare systems [1–3]. In 2010, the British Thoracic Society (BTS) published guidelines on the management of bronchiectasis in adults, along with specific quality standards [4, 5]. To date, these represent the only quality standards available in Europe. These have been tested over a number of years in the UK with progressive improvements in the standard of care [6]. No national guidelines are available in Italy and no indications on which guideline should be followed have been given by the Italian Society of Respiratory Medicine (SIP). There are limited published data on the quality of bronchiectasis care in Europe outside of the UK. The BTS standards have not been tested in continental Europe or in Italy, where information on characteristics and management of bronchiectasis patients are lacking. The majority of the quality standards for the management of bronchiectasis in adults are not met in Italy http://ow.ly/YKMpU

Comparative Effects of a Two-Week Treatment with Nebivolol and Nifedipine in Hypertensive Patients Suffering from COPD

Background: It has been suggested that the antihypertensive agent nebivolol, a β1-adrenoceptor-blocking agent that modulates the endogenous production of nitric oxide, is preferable to ‘conventional’ β1-blockers in hypertensive patients with airway dysfunction. Objectives: Since β1-blockade by nebivolol is larger after repeated dosing than after a single oral intake, we have explored its effect on pulmonary function after a 2-week treatment in hypertensive patients with mild to moderate COPD. Methods: A single-blind crossover design was used. Twenty patients with COPD as selected above and with a diastolic blood pressure of 95–110 mm Hg after 1 week of placebo run-in were entered into the two 2-week active treatment periods with either 5 mg nebivolol (n = 10) or 30 mg nifedipine gastrointestinal-transport-system (GITS) (n = 10) taken for a period of 2 weeks. After a further 1-week washout, subjects were crossed-over to receive the other drug for 2 additional weeks. At each visit, changes in spirometric indexes and the interaction with the bronchodilator effect of salbutamol were investigated. Moreover, systolic and diastolic blood pressure (BP) together with heart rate were manually measured in order to evaluate the cardiovascular effects of the different treatments. Throughout the study, patients recorded symptoms. Results: Similar and significant reductions in systolic and diastolic BP were observed with both treatments. The impact of nifedipine on FEV1 was not significant (p > 0.05), while that of nebivolol was slight. The maximum response to salbutamol was slightly decreased with either nebivolol or nifedipine GITS. Day-to-day airway obstruction control, interpreted from patient recordings of symptom scores and inhaler use, was similar with both treatments. Conclusions: Our pilot study suggests that the use of nebivolol in hypertensive patients with stable mild to moderate COPD was safe during a 2-week trial. Evaluation of longer time periods, larger patient numbers with more severe COPD or during exacerbations is warranted.

Doctor–patient relationship: A resource to improve respiratory diseases management ☆

BACKGROUND Many respiratory diseases are chronic conditions that are strongly linked with the patient-physician relationship, disease perception and therapy adherence. The aim of the present study was to evaluate patients viewpoint about the different aspects involved in their respiratory diseases. METHODS This is a prospective observational survey. 46 Italian medical centres were involved and equally distributed. The interviews were carried out and were performed by means of a questionnaire which consisted of 32 questions regarding lung disease, modality of access to medical facilities, therapy and level of medical assistance. RESULTS 1116 patients were enrolled and the most important respiratory symptoms referred were: dyspnoea (69%), chronic phlegm (28%), cough (13%). During programmed visits 98.3% and 98.8% of interviewed patients knew were aware of asthma and COPD respectively, percentage that dropped, during emergency accesses, to 1.7% and 1.1% knew to have asthma and COPD respectively. Primarily were prescribed 1.67 spirometry/patient/year while only the 2% of patients referred to have performed a blood gas analysis. The 18% of patients spontaneously discontinued the therapy, considering it too complex. The average time that patients identified as being used by the doctor to perform the visit was of 22 minutes, with an high mean medical assistance satisfaction score. DISCUSSION There has been little research examining what factors may influence patient acceptance and participation of chronic respiratory diseases. Our national survey demonstrated that a good patient-physician relationship represents one of the first points in the successful management of respiratory diseases.

RhinAsthma patient perspective: a short daily asthma and rhinitis QoL assessment.

The present study aimed to develop a short validated patient‐completed questionnaire, the RhinAsthma Patient Perspective (RAPP), to assess the health‐related quality of life (HRQoL) in patients with asthma and comorbid allergic rhinitis in clinical practice.

Tiotropium and salmeterol/fluticasone combination do not cause oxygen desaturation in COPD

It has been documented that tiotropium is less likely to induce oxygen desaturation in stable COPD patients compared to long-acting beta2-agonists (LABAs) and combined administration of a LABA and an inhaled corticosteroid (ICS) reduces the potential for acute effects of LABA on blood-gas tensions. In this study, we have compared the acute effects of tiotropium 18 microg and salmeterol/fluticasone combination (SFC) 50/250 microg on arterial blood gases in 20 patients with stable COPD. Each subject was studied on 2 days, separated from one another by at least 4 days. Blood specimens were taken just before the inhalation and at 15, 30, 60, 180 and 360 min after inhalation of each treatment, and spirometry was performed at the same time points. As expected, both treatments significantly improved FEV1 (greatest changes were 0.20 L, 95% CI: 0.13-0.27 at 360 min after tiotropium; and 0.13 L, 95% CI: 0.06-0.19 at 180 min after SFC). The greatest mean changes from baseline in PaO2 were -1.7 (95% CI: -4.0 to 0.6)mmHg, p=0.134, after tiotropium; -0.8 (95% CI: -2.2 to 0.6)mmHg, after SFC. Both changes were observed after 15 min. Both drugs caused a small decrease in PaCO2 (greater changes: -1.9 (95% CI -3.2 to -0.6)mmHg, p=0.005 at 60 min after tiotropium; and -2.4 (95% CI: -3.5 to -1.3) mmHg, p=0.0002 at 180 min after SFC). These results indicate that both tiotropium and SFC are able to induce a significant long-last bronchodilation without affecting arterial blood gases. Moreover, they confirm that the impact of tiotropium on PaO2 is small and without clinical significance and the addition of a LABA to an ICS can reduce the potentially dangerous acute effect of the LABA on blood gases.

Expiratory CT scan in patients with normal inspiratory CT scan: a finding of obliterative bronchiolitis and other causes of bronchiolar obstruction

Expiratory CT scan is usually obtained as supplement to normal inspiratory CT scan to recognize air-trapping, which is expression of small airways obstruction. In some patients the air-trapping may be the only sign of an early-stage small airways disease in an otherwise normal lung.The purpose of this article is to illustrate pathologic conditions, namely obliterative bronchiolitis, in which expiratory CT scan can be abnormal despite normal inspiratory CT examination, and to highlight indications for this technique in patients with clinical and functional suspect of bronchiolar obstruction.

Autoimmunity and COPD: Clinical Implications

&NA; COPD is a leading cause of morbidity and mortality worldwide. Long‐term cigarette smoking is the cause of > 90% of COPD cases in Westernized countries. However, only a fraction of chronic heavy smokers develop symptomatic COPD by age 80. COPD is characterized by an abnormal immune response in the lower airways, and its progression is associated with infiltration of the lung by innate and adaptive inflammatory immune cells that form lymphoid follicles. There is growing evidence that both cellular‐ and antibody‐mediated autoimmunity has a fundamental role in the pathogenesis of stable COPD. In particular, carbonyl‐modified proteins may help to drive autoimmunity in COPD and cause the characteristic small airways abnormalities and even contribute to the pathogenesis of pulmonary emphysema. Although direct, indirect, and circumstantial evidence of a role for autoimmunity in stable patients with COPD has been identified, no cause‐and‐effect relationship between autoimmunity and the mechanisms of COPD has been firmly established in man. As such, the potential contribution of an autoimmune response to the pathogenesis of COPD exacerbation is still being investigated and represents an area of active research. Many drugs targeting autoimmune responses are already available, and the results of controlled clinical trials are awaited with great interest. The potential for measuring specific serum autoantibodies as biomarkers to predict clinical phenotypes or progression of stable COPD is promising.
