Asthma management in a specialist setting: Results of an Italian Respiratory Society survey.

BACKGROUND: Asthma considerably impairs patients' quality of life and increases healthcare costs. Severity, morbidity, and degree of disease control are the major drivers of its clinical and economic impact. National scientific societies are required to monitor the application of international guidelines and to adopt strategies to improve disease control and better allocate resources. AIM: to provide a detailed picture of the characteristics of asthma patients and modalities of asthma management by specialists in Italy and to develop recommendations for the daily management of asthma in a specialist setting. METHOD: A quantitative research program was implemented. Data were collected using an ad hoc questionnaire developed by a group of specialists selected by the Italian Pneumology Society/Italian Respiratory Society. RESULTS: The records of 557 patients were analyzed. In the next few years, specialists are expected to focus their activity patients with more severe disease and will be responsible for selection of patients for personalized biological therapy; however, only 20% of patients attending Italian specialist surgery can be considered severe. In 84.4% of cases, the visit was a follow-up visit requested in 82.2% of cases by the specialist him/herself. The Asthma Control Test is used only in 65% of patients. When available, a significant association has been observed between the test score and asthma control as judged by the physician, although concordance was only moderate (κ = 0.68). Asthma was considered uncontrolled by the specialist managing the case in 29.1% of patients; nevertheless, treatment was not stepped up in uncontrolled or partly controlled patients (modified in only 37.2% of patients). CONCLUSIONS: The results of this survey support re-evaluation of asthma management by Italian specialists. More resources should be made available for the initial visit and for more severely ill patients. In addition, more extensive use should be made of validated tools, and available drugs should be used more appropriately.

The management of asthma in the phenotype and biomarker era: The proposal of a new diagnostic-therapeutic model.

Treatment goals in asthma patients are the achievement of a good control of symptoms and the reduction of the risk of exacerbation. However, a "one-size-fits-all" therapeutic strategy is no longer appropriate to effectively pursue these goals, due to the heterogeneity of asthma. To make the treatment scenario even more complex, asthma patients often present comorbidities that may alter response to therapy. In addition, adherence to asthma treatment is poor. Given this complex and heterogeneous picture, the management of asthma is highly challenging. A clear diagnostic-therapeutic model of patients' care and the definition of the specific responsibilities of different healthcare providers appear necessary to improve clinical outcomes and better allocate healthcare resources. We present here a proposal for this model.

Genuair® Usability Test: Results of a National Public Survey of the Elderly.

Proper use of inhaler devices may be problematic in elderly patients due to age-related difficulties. A survey was administered to elderly patients to investigate the usability of the Genuair® device and patients' subjective viewpoint on the device. A representative sample of the Italian population aged ≥ 65 years was completed with a pre-defined sample of 89 patients with hand arthritis/arthrosis. Of 526 respondents, 88 were not self-sufficient. Only the replies of the 438 self-sufficient respondents were analyzed. A total of 107 participants (24%) reported having respiratory diseases, and 81 of these (76%) were users of inhaler devices. After the first test, the device was considered "practical/handy" by 90% of patients and "easy to use" by 89%. After the second test, in which patients received a demonstration of the correct inhalation maneuver, the percentage of patients scoring ≥ 7 increased to 93% for the first characteristic and was confirmed for the second, with no differences between the groups in terms of age, educational level, use of devices, and presence of arthritis/arthrosis. The mean time to explain the inhaler technique and to perform a correct inhalation was 1'38"± 1'37", and 70% of the respondents required less than 2 minutes, with no differences between the groups in terms of age, education level, use of devices, and presence of arthritis/arthrosis. In conclusion, Genuair® was well accepted and easy to use in a representative sample of the Italian population aged ≥ 65 years. These characteristics make it a valid choice in the elderly, thus enabling patients to better cope with the problems and difficulties that are common to this age group.

Disability in moderate chronic obstructive pulmonary disease: prevalence, burden and assessment - results from a real-life study.

BACKGROUND: The role of disability and its association with patient-reported outcomes in the nonsevere forms of chronic obstructive pulmonary disease (COPD) has never been explored. OBJECTIVES: The aim of this study was to assess, in a cross-sectional real-life study, the prevalence and degree of disability in moderate COPD patients and to assess its association with health status, illness perception, risk of death and well-being. METHODS: Moderate COPD outpatients attending scheduled visits were involved in a quantitative research program using a questionnaire-based data collection method. RESULTS: Out of 694 patients, 17.4% were classified as disabled and 47.6% reported the loss of at least one relevant function of daily living. Disabled patients did not differ from nondisabled patients in terms of working status (p = 0.06), smoking habits (p = 0.134) and ongoing treatment (p = 0.823); however, the former showed a significantly higher disease burden as measured by illness perception, health status and well-being. The stepwise regression analysis showed that the modified Medical Research Council (mMRC) score was the most relevant factor related to COPD disability (F = 38.248; p = 0.001). Patient stratification was possible according to the forced expiratory volume in 1 s (FEV1) value and an mMRC score ≥2, which identified disabled patients, whereas the mMRC values were differently associated with the risk of disability. CONCLUSION: A significant proportion of individuals with moderate COPD reported a limitation of daily life functions, with dyspnea being the most relevant factor inducing disability. Adding the evaluation of patient-reported outcomes to lung function assessment could facilitate the identification of disabled patients.

Competence and training in interventional pulmonology.

Interventional pulmonology (IP) is experiencing a rapid evolution of new technologies. There is a need to develop structured training programs, organized in high volume expert centers in order to improve trainee education, and including the development of validated metrics for their competency assessment. Concerning teaching methods, a gradual progression from theory to practice, using new teaching techniques, including live sessions and low and high-fidelity simulation, flipped classroom models and problem-based learning (PBL) exercises would provide a training setting more suitable for our current need to improve skills and update professionals. Training programs should be learner-centered and competence-oriented, as well as being based on a spiral-shaped approach in which the same subject is addressed many times, from new and different perspectives of knowledge, ability, behavior and attitude, until the trainee has demonstrated a high degree of skill and professionalism. Furthermore there is a need to standardize the training programs as guide for physicians wishing to undertake a gradual and voluntary improvement of their own competencies, and assist those planning and organizing training programs in IP. The article includes a general part on core curriculum contents, innovative training methods and simulation, and introduces the following articles on the skills that the Interventional Pulmonologist must master in order to perform the different procedures. This monography should be considered a starting point that will evolve over time and results in better training for practitioners and better care for our patients. The task of establishing a trainee's competence to practice independently as an Interventional Pulmonologist remains the responsibility of the IP fellowship program director and faculty, who validate logbooks and assess competence for each procedure. These standards need to be reviewed and approved by national and International Scientific Societies and Healthcare Institutions with the aim to improve, disseminate and incorporate them in healthcare programs.

COPD management as a model for all chronic respiratory conditions: report of the 4th Consensus Conference in Respiratory Medicine.

BACKGROUND: Non-communicable diseases (NCDs) kill 40 million people each year. The management of chronic respiratory NCDs such as chronic obstructive pulmonary disease (COPD) is particularly critical in Italy, where they are widespread and represent a heavy burden on healthcare resources. It is thus important to redefine the role and responsibility of respiratory specialists and their scientific societies, together with that of the whole healthcare system, in order to create a sustainable management of COPD, which could become a model for other chronic respiratory conditions. METHODS: These issues were divided into four main topics (Training, Organization, Responsibilities, and Sustainability) and discussed at a Consensus Conference promoted by the Research Center of the Italian Respiratory Society held in Rome, Italy, 3-4 November 2016. RESULTS AND CONCLUSIONS: Regarding training, important inadequacies emerged regarding specialist training - both the duration of practical training courses and teaching about chronic diseases like COPD. A better integration between university and teaching hospitals would improve the quality of specialization. A better organizational integration between hospital and specialists/general practitioners (GPs) in the local community is essential to improve the diagnostic and therapeutic pathways for chronic respiratory patients. Improving the care pathways is the joint responsibility of respiratory specialists, GPs, patients and their caregivers, and the healthcare system. The sustainability of the entire system depends on a better organization of the diagnostic-therapeutic pathways, in which also other stakeholders such as pharmacists and pharmaceutical companies can play an important role.

Serum anti-p53 autoantibodies in pleural malignant mesothelioma, lung cancer and non-neoplastic lung diseases.

Alterations of the p53 gene may lead to the production of detectable autoantibodies (p53-Abs) in cancer patients. In order to evaluate the association of p53-Abs with pleuropulmonary diseases, four groups of subjects were analyzed by ELISA for serum p53-Abs, in the framework of a molecular epidemiologic study. Two of 30 pleural malignant mesothelioma patients (MM; 6.7%) and 8/48 lung cancer patients (LC; 16.7%) were seropositive, while all 51 healthy controls (HC) were negative. Two of 55 (3.6%) at-risk controls (RC) with non-malignant respiratory diseases were positive and were not subsequently diagnosed any cancer. The difference was statistically significant between LC and RC or HC (P = 0.01), but not between MM and any other group. No correlation was found with age, sex, cancer stage or histology, cigarette smoking or occupational exposure. A longer survival (not significant) was shown in seropositive LC but not in MM. p53 expression in tumor tissue was also evaluated in a subgroup of MM. In conclusion, the presence of detectable p53-Abs in serum was associated in a statistically significant proportion of cases with LC but only occasionally with MM. The longer survival among positive LC patients and the presence of two seropositive among patients with non-neoplastic respiratory diseases should be further investigated.

The clinical and integrated management of COPD. An official document of AIMAR (Interdisciplinary Association for Research in Lung Disease), AIPO (Italian Association of Hospital Pulmonologists), SIMER (Italian Society of Respiratory Medicine), SIMG (Italian Society of General Medicine).

COPD is a chronic pathological condition of the respiratory system characterized by persistent and partially reversible airflow obstruction, to which variably contribute remodeling of bronchi (chronic bronchitis), bronchioles (small airway disease) and lung parenchyma (pulmonary emphysema). COPD can cause important systemic effects and be associated with complications and comorbidities. The diagnosis of COPD is based on the presence of respiratory symptoms and/or a history of exposure to risk factors, and the demonstration of airflow obstruction by spirometry. GARD of WHO has defined COPD "a preventable and treatable disease". The integration among general practitioner, chest physician as well as other specialists, whenever required, assures the best management of the COPD person, when specific targets to be achieved are well defined in a diagnostic and therapeutic route, previously designed and shared with appropriateness. The first-line pharmacologic treatment of COPD is represented by inhaled long-acting bronchodilators. In symptomatic patients, with pre-bronchodilator FEV1 < 60% predicted and ≥ 2 exacerbations/year, ICS may be added to LABA. The use of fixed-dose, single-inhaler combination may improve the adherence to treatment. Long term oxygen therapy (LTOT) is indicated in stable patients, at rest while receiving the best possible treatment, and exhibiting a PaO2 ≤ 55 mmHg (SO2 < 88%) or PaO2 values between 56 and 59 mmHg (SO2 < 89%) associated with pulmonary arterial hypertension, cor pulmonale, or edema of the lower limbs or hematocrit > 55%. Respiratory rehabilitation is addressed to patients with chronic respiratory disease in all stages of severity who report symptoms and limitation of their daily activity. It must be integrated in an individual patient tailored treatment as it improves dyspnea, exercise performance, and quality of life. Acute exacerbation of COPD is a sudden worsening of usual symptoms in a person with COPD, over and beyond normal daily variability that requires treatment modification. The pharmacologic therapy can be applied at home and includes the administration of drugs used during the stable phase by increasing the dose or modifying the route, and adding, whenever required, drugs as antibiotics or systemic corticosteroids. In case of patients who because of COPD severity and/or of exacerbations do not respond promptly to treatment at home hospital admission should be considered. Patients with "severe" or "very severe" COPD who experience exacerbations should be carried out in respiratory unit, based on the severity of acute respiratory failure. An integrated system is required in the community in order to ensure adequate treatments also outside acute care hospital settings and rehabilitation centers. This article is being simultaneously published in Sarcoidosis Vasc Diffuse Lung Dis 2014, 31(Suppl. 1);3-21.

The bacterial lysate Lantigen B reduces the number of acute episodes in patients with recurrent infections of the respiratory tract: the results of a double blind, placebo controlled, multicenter clinical trial.

Studies in the 1970s and 1980s reported that bacterial lysates (BL) had a prophylactic effect on recurrent respiratory tract infections (RRTI). However, controlled clinical study procedures have evolved substantially since then. We performed a trial using updated methods to evaluate the efficacy of Lantigen B®, a chemical BL. This double blind, placebo controlled, multi-center clinical trial had the primary objective of assessing the capacity of Lantigen B to significantly reduce the total number of infectious episodes in patients with RRTI. Secondary aims were the RRTI duration, the frequency and the severity of the acute episodes, the use of drugs and the number of missed workdays. In the subgroup of allergic patients with RRTI, the number of allergic episodes (AE) and the use of anti-allergic drugs were also evaluated. One hundred and sixty patients, 79 allocated to the treated group (TG) and 81 to the placebo group (PG), were enrolled; 30 were lost during the study and 120 (79 females and 38 males) were evaluated. The PG had 1.43 episodes in the 8-months of follow-up while the TG had 0.86 episodes (p=0.036). A similar result was observed in the allergic patients (1.80 and 0.86 episodes for the PG and the TG, respectively, p=0.047). The use of antibiotics was reduced (mean 1.24 and 2.83 days of treatment for the TG and the PG). Logistic regression analysis indicated that the estimated risk of needing antibiotics and NSAIDs was reduced by 52.1 and 30.6%, respectively. With regard to the number of AE, no significant difference was observed between the two groups, but bronchodilators, antihistamines and local corticosteroids were reduced by 25.7%, 56.2% and 41.6%, respectively, in the TG. Lantigen B significantly reduced the number of infectious episodes in patients with RRTI. This finding suggests a first line use of this drug for the prophylaxis of infectious episodes in these patients.

Formoterol by pressurized metered-dose aerosol or dry powder on airway obstruction and lung hyperinflation in partially reversible COPD.

BACKGROUND: We compared the efficacy and safety of formoterol given by a pressurized metered-dose inhaler (pMDI) (Atimos®, Chiesi Farmaceutici, Italy), using a chlorine-free hydrofluoroalkane (HFA-134a) propellant developed to provide stable and uniform dose delivery (Modulite™, Chiesi Farmaceutici, Italy), with formoterol by dry powder inhaler (DPI) (Foradil® Aerolizer®, Novartis Pharmaceuticals) and placebo, in reducing airflow obstruction and lung hyperinflation, in moderate-to-severe, partially reversible chronic obstructive pulmonary disease (COPD). METHODS: Forty-eight patients were randomized to a 1-week, double-blind, double-dummy, three-period crossover study with 12 µg b.i.d. of formoterol given by pMDI or DPI, or placebo. Spirometry, specific airway conductance, and lung volumes were measured at the beginning and at the end of each treatment period from predose to 4 h postdose. A 6-min walking test was carried out 4 h after the first and the last dose, with dyspnea assessed by Borg scale. Safety was assessed through adverse events monitoring electrocardiography and vital signs. RESULTS: The two formulations of formoterol were significantly superior to placebo but not different from each other in increasing 1-sec forced expiratory volume, specific airway conductance, inspiratory capacity, and inspiratory-to-total lung capacity ratio. The two active treatments were also equivalent and superior to placebo in reducing dyspnea at rest and on exertion. No differences in terms of safety between the two active forms and placebo were detected. CONCLUSIONS: Formoterol given with chlorine-free pMDI was equivalent to DPI in reducing airway obstruction and lung hyperinflation in COPD patients. Both formoterol formulations confirmed the good safety profile similar to placebo.

Induction chemotherapy with carboplatin-paclitaxel followed by standard radiotherapy with concurrent daily low-dose cisplatin plus weekly paclitaxel for inoperable non-small-cell lung cancer.

Both induction chemotherapy and concurrent platinating agents have been shown to improve results of thoracic irradiation in the treatment of locally advanced non-small-cell lung cancer (NSCLC). This phase II study investigated activity and feasibility of a novel chemoradiation regimen, including platinum and paclitaxel, both as induction chemotherapy and concurrently with thoracic radiotherapy. Previously untreated patients with histologically/cytologically proven unresectable stage I-III NSCLC were eligible. Induction chemotherapy consisted of 2 courses of 200 mg/m2 paclitaxel and carboplatin at AUC of 6 mg/mL/min every 3 weeks. From day 43, continuous thoracic irradiation (60 Gy in 30 fractions radiotherapy for 6 weeks) was given concurrently with daily cisplatin at a dose of 5 mg/m2 intravenously and weekly paclitaxel at a dose of 45 mg/m2 for 6 weeks. Fifteen patients were accrued in the first stage of the trial. According to the previous statistical considerations, accrual at the second stage of the study was halted as a result of the achievement an insufficient number of successes. Major toxicity of combined chemoradiation was grade III-IV esophagitis requiring hospitalization for artificial nutrition, which occurred in 58% of patients. Other toxicities included grade II-IV fatigue in 75% of patients and grade I-IV neuromuscular toxicity in 67%. Only 7 patients completed the treatment program as scheduled. Eight patients (53.3%; 95% confidence interval, 26.5-78.7%) had a major response (5 partial response, 3 complete response), 2 patients had disease progression, and 1 was stable at the end of treatment. Four patients died early. With a median follow up of 38 months, the median survival was 12 months. A combined chemoradiation program, including platinum and paclitaxel, appears difficult to deliver at full dose as a result of toxicity, mainly esophagitis. More active and less toxic combined modality treatments need to be developed for inoperable NSCLC.

Comparison of DNA adduct levels in nasal mucosa, lymphocytes and bronchial mucosa of cigarette smokers and interaction with metabolic gene polymorphisms.

The recent introduction of biomarkers in population studies of lung cancer has improved the traditional epidemiological approach, especially in the detection of high risk groups. Many inhalable carcinogens form DNA adducts, an initial event in lung carcinogenesis, and therefore the identification of easily accessible sources of DNA for population studies is considered a leading priority in the field. In this study we compared the frequency of DNA adducts in samples from nasal brushing, bronchial biopsy and peripheral blood lymphocytes (PBL) in a group of 55 subjects, both smokers and non-smokers, undergoing bronchoscopy for diagnostic purposes. Polymorphisms in the CYP1A1, GSTM1 and GSTT1 genes were also evaluated. The level of DNA adducts measured by (32)P-labelling assay in nasal mucosa (10(8) relative adduct level, mean +/- SD 1.10 +/- 0.66) was higher than in bronchial mucosa (0.82 +/- 0.36) and in PBL (0.54 +/- 0.39, P < 0.01). DNA adducts measured in nasal mucosa and in PBL were correlated with those in bronchial mucosa (P < 0.01 and P < 0.05, respectively). DNA adducts in smokers were significantly increased in both nasal mucosa and PBL, with a significant dose-response linear trend (P < 0.05). No significant effect on DNA adduction of the genetic polymorphisms investigated was found. Nasal mucosa brushing proved to be a suitable procedure for the (32)P-labelling assay and its use in population studies should be further explored.
