Late diagnosis limits therapeutic options and survival rate of non-small cell lung cancer (NSCLC) patients. Therefore the identification of biomarkers represents an emerging medical need. A highly sensitive and specific test was developed to identify/quantify a novel/selective diagnostic biomarker for NSCLC patients, caspase-4. This test was validated by using i) plasma from 125 NSCLC patients and 79 healthy (non-pathological) subjects, ii) plasma from 139 smokers and iii) from 70 chronic-obstructive pulmonary disease (COPD) patients. Caspase-4 quantification was also assessed in the lung tumor mass of 98 paired NSCLC patients compared to 10 non-tumor lung tissues (i.e. tuberculosis). Circulating caspase-4 was detected in both healthy and NSCLC patients; however at different range values: 2.603-3.372 ng/ml for NSCLC patients (95% CI) compared to 0.3994-0.6219 ng/ml for healthy subjects (95% CI). The sensitivity of the test ranged from 97.07% to 100%; the specificity was 88.1% with a positive predictive value of 92.54%, accuracy of 95.19% and AUC of 0.971. Smokers (95% CI, 0.3947-0.6197 ng/ml) and COPD patients (95% CI, 1.703-2.995 ng/ml) showed intermediate values of circulating caspase-4. Tissue levels of caspase-4 in the tumor mass showed that 72 (72.7%) out of 99 patients were positive. More importantly, higher levels (cut-off value = 0.307 ng/ml) of caspase-4 in the tumor mass were associated to reduced overall survival (median 0.92 years) compared to NSCLC patients with lower levels (median 3.02 years). We report for the first time caspase-4 as a novel diagnostic and prognostic biomarker, opening new therapeutic perspectives for NSCLC patients.

Objectives To apply the Delphi exercise with iterative involvement of radiologists and pulmonologists with the aim of defining a structured reporting template for high-resolution computed tomography (HRCT) of patients with fibrosing lung disease (FLD). Methods The writing committee selected the HRCT criteria—the Delphi items—for rating from both radiology panelists (RP) and pulmonology panelists (PP). The Delphi items were first rated by RPs as “essential”, “optional”, or “not relevant”. The items rated “essential” by

Since the introduction of biologics for the treatment of rheumatoid arthritis (RA), psoriatic arthritis (PsA), ankylosing spondylitis (AS), and psoriasis (Pso) an increased risk of tuberculosis (TB) reactivation in patients with latent tuberculosis infection (LTBI) has been recorded for anti-TNF agents, while a low or absent risk is associated with the non-anti-TNF targeted biologics. To reduce this risk several recommendation sets have been published over time, but in most of them the host-related risk, and the predisposing role to TB reactivation exerted by corticosteroids and by the traditional disease-modifying anti-rheumatic drugs has not been adequately addressed. Moreover, the management of the underlying disease, and the timing of biologic restarting in patients with TB occurrence have been rarely indicated. A multidisciplinary expert panel, the Italian multidisciplinary task force for screening of tuberculosis before and during biologic therapy (SAFEBIO), was constituted, and through a review of the literature, an evidence-based guidance for LTBI detection, identification of the individualized level of risk of TB reactivation, and practical management of patients with TB occurrence was formulated. The literature review confirmed a higher TB risk associated with monoclonal anti-TNF agents, a low risk for soluble receptor etanercept, and a low or absent risk for non-anti-TNF targeted biologics. Considering the TB reactivation risk associated with host demographic and clinical features, and previous or current non-biologic therapies, a low, intermediate, or high TB reactivation risk in the single patient was identified, thus driving the safest biologic choice. Moreover, based on the underlying disease activity measurement and the different TB risk associated with non-biologic and biologic therapies, practical indications for the treatment of RA, PsA, AS, and Pso in patients with TB occurrence, as well as the safest timing of biologic restarting, were provided.

In recent years Tumor Necrosis Factor alpha (TNF alfa) inhibitors have been highly effective in treating rheumatoid arthritis (RA). However, patients receiving these inhibitors have an increased risk of developing tuberculosis (TB). We describe a rare case of tuberculosis of the tongue in an RA patient treated with methotrexate (MTX) and the TNF alfa inhibitor adalimumab (ADA) for the previous six years. Pretreatment tuberculin skin test (TST) was negative. The patient was admitted to our division complaining of a sore throat for months. Clinical examination revealed a swollen non-healing ulcer at the base of the tongue, which was suspected to be a squamous cell carcinoma. Histopathological assessment unexpectedly revealed a chronic granulomatous inflammation compatible with tuberculosis. TST was strongly positive and the T Spot TB test was also reactive. MTX and ADA were discontinued and the patient received antituberculous treatment with complete healing of the lesion. After three months our patient had a worsening RA that was treated with MTX and rituximab with no TB related adverse events. This case highlights the importance of considering tuberculosis in the differential diagnosis of ulcerative lesions of the oral cavity, especially in immunocompromised patients treated with TNF alfa inhibitors. Rituximab can be a valid alternative therapy in such patients.

Bronchial asthma is a disease in which psychological implications play a role in increasing or in reducing the severity of bronchial obstruction. Internet and, in particular, social media are increasingly a part of daily life of both young and adult people, thus allowing virtual relationships with peers sharing similar interests and goals. Although social network users often disclose more about themselves online than they do in person, there might be a risk for adolescents and for sensitive individuals, who can be negatively influenced by an incorrect use. However, although some studies show an increased risk of depression, other observations suggest beneficial effects of social network by enhancing communication, social connection and self-esteem. In addition, social network represent a useful tool in disseminating public health messages.

Tuberculosis (TB) is the most deadly infectious disease in the world. TB control relies on passive case findings and targeted treatment of latently infected individuals at high risk of disease progression. Tuberculin skin testing (TST) is conventionally used for detection of TB infection. Recently, blood assays measuring the release of IFN-gamma by TB-specific effector memory T cells have been developed to overcome TST limitations. Overall, IFN-gamma release assays are more specific than TST, more sensitive in detecting active TB and correlate better with TB exposure in immune-competent patients, at least in low-burden settings. There are three US FDA-approved assays commercially available: the ELISpot-based assay T-SPOT.TB (Oxford Immunotech, UK) and two ELISA-based formats, QuantiFERON TB Gold (QFT) and QFT-in tube (Cellestis, Australia). Recent international guidelines and consensus statements recommend the use of IFN-gamma release assays at different levels in TB management. However, conclusive evidence-based information targeting populations at high TB risk, including HIV-infected individuals, children and patient candidates for biotherapy with TNF-alpha blockers, are lacking. The aim of this review is to focus our attention on studies addressing the performance of commercial IFN-gamma release assays in clinical management of TB infection in these highly selected settings to provide a more comprehensive picture of the actual scenario and to identify areas to be investigated further.

Main etiologic agents of AIDS-related infections pneumonia and diagnostic tools useful to identify microorganism are discussed. Bronchoalveolar lavage (BAL) remains the most important performed technique to collect pulmonary secretions, but it needs to be completed by colorimetric, immunological (monoclonal antibodies), serological (ELISA vs. mycobacterial antigens), molecular (DNA probes) techniques. These tools are very useful to identify pathogen agents.

This article reports the study protocol of a nationwide multicentric study in seven Italian regions aimed at assessing the effectiveness of a digitally supported approach for the early screening of frailty risk factors in community-dwelling older adults. SUNFRAIL+ is a prospective observational cohort study aimed at carrying out a multidimensional assessment of community-dwelling older adults through an IT platform, which allows to connect the items of the SUNFRAIL frailty assessment tool with a cascading multidimensional in-depth assessment of the bio–psycho–social domains of frailty. Seven centers in seven Italian regions will administer the SUNFRAIL questionnaire to 100 older adults. According to the answers provided by older adults, they will be subjected to one or more validated in-depth scale tests in order to perform further diagnostic or dimensional evaluations. The study aims to contribute to the implementation and validation of a multiprofessional and multistakeholder service model for the screening of frailty in community-dwelling older adult population.

Background The aims of this study were: to investigate the capacity of the rare disease healthcare network in Campania to diagnose patients with rare diseases during the outbreak of Covid-19; and to shed light on problematic diagnoses during this period. Methods To describe the impact of the Covid-19 pandemic on the diagnosis of patients with rare diseases, a retrospective analysis of the Campania Region Rare Disease Registry was performed. A tailored questionnaire was sent to rare disease experts to investigate major issues during the emergency period. Results Prevalence of new diagnoses of rare disease in March and April 2020 was significantly lower than in 2019 (117 versus 317, P Conclusions This study describes the effects of the Covid-19 outbreak on the diagnosis of rare disease in a single Italian region and investigates potential issues of diagnosis and management during this period.

Background: Polyphenols are the largest class of bioactive compounds in plants, which are synthesized as secondary metabolites. In the last few years, interesting studies have demonstrated the efficacy of polyphenols against coronavirus infections. Methods: we conducted a phase II multicentric clinical trial (TAEROVID-19) during the first wave of the COVID-19 pandemic in order to assess the safety and feasibility of Taurisolo® aerosol formulation in hospitalized patients suffering from SARS-CoV-2 pneumonia. Results: we observed a rapid decline of symptoms and a low rate of intensive care in patients treated with Taurisolo®, with a faster decline of symptoms. Conclusions: This is the first trial assessing the safety and feasibility of Taurisolo® aerosol formulation. We could argue that this treatment could act as an add-on therapy in the treatment of COVID-19 patients, owing to both its anti-inflammatory and antioxidant effects. Further controlled trials are needed, which may be of interest to evaluate the compound’s efficacy.

Background: Currently, the prognosis of bronchiectasis is based on different prognostic indicators, like BSI and FACED score, founded on clinical-demographic, functional and radiological criteria. Both scoring systems include the number of lobes involved in bronchiectasis, which represents an adverse prognostic index. Our study aimed to investigate the prognostic role of the clinical-functional parameters and the number of involved lobes ratio in adult bronchiectasis.Methods: The study was conducted on 52 patients diagnosed with non-cystic fibrosis bronchiectasis (NCFB) between 2015 and 2017 who attended the Pneumology Unit of Monaldi Hospital in Naples, Italy. Correlations between clinical-functional parameters (BMI, smoking history, number of exacerbations in the previous year, spirometry, DLCO, ABG test and 6MWT) and number of involved lobes were investigated.Results: At baseline, the number of exacerbations in the previous year had a statistically significant association with the number of involved lobes. Furthermore, at baseline, the radiological criterion was also negatively associated with some functional parameters (FEV1/FVC ratio e FEF25-75%). Statistical significance was lost during the follow-up, demonstrating the effectiveness of the therapy.Conclusions: Imaging extension represents a promising biomarker of disease severity as well as a helpful follow-up tool for non-Cystic Fibrosis bronchiectasis (NCFB).

Body composition and muscle strength are emerging aspects in idiopathic pulmonary fibrosis (IPF) clinical assessment. We aimed to study the relationships of handgrip strength (HGS) with anthropometric variables, body composition, and disease staging, and to evaluate the prevalence of dynapenia in 102 clinically stable IPF patients (70 M; mean age: 69.4 years). Fat-free mass (FFM), skeletal muscle (SM) were estimated with bioimpedance analysis. HGS was measured with a digital handle dynamometer for both dominant and non-dominant body sides. Dynapenia was identified according to six recognized criteria sets. Mean body mass index (BMI) was 28.2 ± 4.7 kg/m2, with a prevalence of overweight (BMI > 25 and 2) and obesity (BMI ≥ 30 kg/m2) of 35% and 37%, respectively. FFM and SM were greater in males, whereas percentage body fat was higher in women. HGS was higher and declined with age slightly more rapidly in men, showing a stronger correlation with FFM and SM. Dynapenia prevalence ranged from 20.6 to 56.9%, depending on the criteria used, and was more frequent in older patients and advanced disease. Dynapenia is highly prevalent in IPF. HGS is a promising proxy marker of muscle function to be used in clinical evaluation and follow-up programs.

Studies have shown that the pandemic has led to an increase in sick leave periods among healthcare workers (HCWs); however, this might have changed over time considering increase in vaccination coverage and change in COVID-19 variant predominance. Therefore, we conducted an observational study to evaluate whether the type of symptoms and the duration of sick leave period for healthcare workers working in a large university hospital in the South of Italy changed between January 2021 and January 2022; 398 cases of COVID-19 were identified for a total of 382 subjects involved. A total of 191 subjects answered the questionnaire about symptoms; of these, 79 had COVID-19 during the period from March 2020 until February 2022. The results showed a decrease of about 1.2 days in sick leave period for each quarter without finding significant differences in the perception of symptoms. It is possible to hypothesize a contribution from the Omicron variant to the decrease in sick leave period in the last quarter, from vaccination coverage, from optimization of COVID-19 management, and from change in the regulations for the assessment of positivity.

Background Idiopathic pulmonary fibrosis (IPF) is a complex disease with a highly variable clinical course and generally poor prognosis. Classified as a rare disease, significant increases in incidence have been recorded worldwide in recent years. Left untreated IPF is extremely debilitating with substantial personal, social and economic implications. Objectives To discuss how IPF is diagnosed and managed in real life clinical practice with particular reference to Italy and to determine how new and effective therapies can be incorporated into a patient-centred management approach in order to improve the lives of patients with IPF. Outcomes Barriers to early diagnosis are discussed. Cited reasons for delays in diagnosing IPF in Italy include: inherent difficulties in diagnosis; lack of knowledge/awareness of the condition among point-of-contact healthcare professionals; delays in referral to centres of excellence and underestimation of symptoms by both patients and healthcare workers. Valid therapeutic options with demonstrated efficacy in slowing the decline in lung function are now available for patients with IPF. The ASCEND trial confirmed the effects of pirfenidone, approved for the treatment of IPF on the basis of the four phase III trials. Nintedanib, a tyrosine kinase inhibitor that targets the PDGF receptors α/β, FGF receptors 1 to 3, and VEGF receptors 1–3, is approved in the USA and the EU for the treatment of IPF. The TOMORROW and the INPULSIS placebo controlled trials in patients with IPF confirm the efficacy and safety of nintedanib and recent interim analyses endorse its long-term effects in slowing disease progression. Conclusions The importance of early and accurate diagnosis of IPF cannot be underestimated and it is the duty of all healthcare professionals to be vigilant to the symptoms of IPF and to involve a multidisciplinary team in diagnosing and managing IPF early in the course of disease.

International audience; The fifth report issued by the Intergovernmental Panel on Climate Change forecasts that greenhouse gases will increase the global temperature as well as the frequency of extreme weather phenomena. An increasing body of evidence shows the occurrence of severe asthma epidemics during thunderstorms in the pollen season, in various geographical zones. The main hypotheses explaining association between thunderstorms and asthma claim that thunderstorms can concentrate pollen grains at ground level which may then release allergenic particles of respirable size in the atmosphere after their rupture by osmotic shock. During the first 20–30 min of a thunderstorm, patients suffering from pollen allergies may inhale a high concentration of the allergenic material that is dispersed into the atmosphere, which in turn can induce asthmatic reactions, often severe. Subjects without asthma symptoms, but affected by seasonal rhinitis can also experience an asthma attack. All subjects affected by pollen allergy should be alerted to the danger of being outdoors during a thunderstorm in the pollen season, as such events may be an important cause of severe exacerbations. In light of these observations, it is useful to predict thunderstorms and thus minimize thunderstorm-related events.

Introduction: Gender, age, physiology (GAP) system have proven to be an easy tool for predicting disease stages and survival in idiopathic pulmonary fibrosis (IPF) patients. Objective: To validate mortality risk as determined by the GAP system in a real-life multicentre IPF population treated with pirfenidone. Methods: The study included patients who received pirfenidone for at least 6 months. The GAP calculator and the GAP index were determined. The primary outcome was all-cause mortality. The prognostic accuracy of the GAP system was evaluated with respect to calibration and discrimination. Results and Conclusion: Sixty-eight IPF patients were enrolled in the study. The median follow-up was 2.4 years (range 0.1-7.4 years). A total of 22 deaths as first event (32%) and of 10 lung transplantation (15%) were recorded. The cumulative incidence of mortality at 1, 2 and 3 years was 10.4%, 22.4% and 38.4%, respectively. The differences between the predicted and observed mortality were not significant for the GAP index while the observed mortality become comparable to that predicted by the GAP calculator only in the third year of follow-up. The C-index for the GAP index was 0.74 (95% CI 0.57-0.93) while the C-statistic value for the GAP calculator was 0.77 (95% CI 0.59-0.95).

Long-acting β 2 -adrenoceptor agonists, formoterol and salmeterol, represent a milestone in the treatments of chronic obstructive lung diseases. Although no specific indications concerning the choice of one molecule rather than another are provided by asthma and COPD guidelines, they present different pharmacological properties resulting in distinct clinical employment possibilities. In particular, salmeterol has a low intrinsic efficacy working as a partial receptor agonist, while formoterol is a full agonist with high intrinsic efficacy. From a clinical perspective, in the presence of low β 2 -adrenoceptors availability, like in inflamed airways, a full agonist can maintain its bronchodilatory and non-smooth muscle activities while a partial agonist may be less effective. Furthermore, formoterol presents a faster onset of action than salmeterol. This phenomenon, combined with the molecule safety profile, leads to a prompt amelioration of the symptoms, and allows using this drug in asthma as an "as needed" treatment in patients already on regular treatment. The fast onset of action and the full agonism of formoterol need to be considered in order to select the best pharmacological treatment of asthma and COPD.

Background: The weight loss induced by bariatric surgery (BS) improves asthma clinical control evaluated usually after a short time. The long-term effects of weight loss attained by BS on asthma control and health related-quality of life (HRQoL) in patients affected by asthma and obesity are not known. Objective: To investigate the five-year effect of weight reduction induced by BS on asthma control, quality of life and pulmonary functional parameters in severely obese intermittent or mild-to-moderate asthmatic patients. Methods: Twenty-six consecutive severe obese subjects with previous diagnosis of asthma with indication for laparoscopic adjustable gastric banding (LAGB) were enrolled into the study. Fifteen of them agreed to undertake the surgery (treatment group, TG) while the remaining eleven non-operated patients represented the control group (CG). Body mass index (BMI), Asthma Control Test (ACT), Mini Asthma Quality of Life Questionnaire (mini-AQLQ) and spirometric parameters were evaluated at baseline and after one and five years from surgery. Results: Mean BMI of TG significantly decreased at one and five years after the surgery, while it remained unchanged in CG. After surgery, both the overall ACT and the mini-AQLQ score significantly improved in TG after one year, persisting improved after 5-years (p < 0.001), while these outcomes remained unchanged in CG. As compared with the pre-surgery values, the percentage of predicted FEV1 and FVC significantly increased at five-year follow-up from surgery in TG, while it remained unchanged in CG. Conclusions: In severe obese asthmatic patients, the significant improvement of asthma control test and HRQoL, observed one year after LAGB, persists five years after surgery.

Previous studies of the occurrence of interstitial lung disease (ILD) in undifferentiated connective tissue diseases (UCTD) were conducted in patients admitted to Respiratory Medicine Units. The aim of the present prospective study was to investigate lung involvement in UCTD patients admitted to a Rheumatology Unit. Eighty-one consecutive UCTD patients were enrolled in the study. Each patient underwent history and physical examination, routine laboratory investigations, antinuclear antibody (ANA) profiling, B-mode echocardiography, and lung function study according to previously reported methods. Lung high resolution computed tomography (HRCT) was performed in patients who provided informed consent. Six patients (7.4%) had a history of grade II dyspnea. Three of them had a DLCO ranging from 42 to 55% of the predicted value; and a HRCT-documented ILD with a non-specific interstitial pneumonia (NSIP) pattern. Symptoms in the other three patients were due to cardiac disease. None of the 75 asymptomatic patients, had relevant findings at physical examination, 26/75 had a DLCO

An association between biologic agents and reactivation of active disease from latent tuberculosis infection (LTBI) has been established. Screening for LTBI is, therefore, now recommended for candidates for biologic drugs. The tuberculin skin test (TST) and interferon-γ release assays (IGRA) are the available commercial tests for detecting LTBI. We discuss their accuracy in immune-competent subjects and patients with autoimmune diseases, as well as potential new approaches to immune diagnosis. IGRA seem to be more accurate than TST in bacillus Calmette-Guerin vaccinated subjects and patients with autoimmune diseases. However, longitudinal studies are needed to estimate the risk of progression to TB after IGRA-based and/or TST-based diagnosis of LTBI in these vulnerable patients. New tests are needed to identify those patients with LTBI who will develop active TB and need prophylaxis.

Treatment of latent tuberculosis infection (LTBI) is a key component in TB control strategies worldwide. However, as people with LTBI are neither symptomatic nor contagious, any screening decision should be weighed carefully against the potential benefit of preventing active disease in those who are known to be at higher risk and are willing to accept therapy for LTBI. This means that a targeted approach is desirable to maximize cost effectiveness and to guarantee patient adherence. We focus on LTBI treatment strategies in patient populations at increased risk of developing active TB, including candidates for treatment with tumor necrosis factor-α blockers. In the last 40 years, isoniazid (INH) has represented the keystone of LTBI therapy across the world. Although INH remains the first therapeutic option, alternative treatments that are effective and associated with increased adherence and economic savings are available. Current recommendations, toxicity, compliance, and cost issues are discussed in detail in this review. A balanced relationship between the patient and healthcare provider could increase adherence, while cost-saving treatment strategies with higher effectiveness, fewer side effects, and of shorter duration should be offered as preferred.

Despite major advances in the treatment of asthma and the development of several asthma guidelines, people still die of asthma currently. According to WHO estimates, approximately 250,000 people die prematurely each year from asthma. Trends of asthma mortality rates vary very widely across countries, age and ethnic groups. Several risk factors have been associated with asthma mortality, including a history of near-fatal asthma requiring intubation and mechanical ventilation, hospitalization or emergency care visit for asthma in the past year, currently using or having recently stopped using oral corticosteroids (a marker of event severity), not currently using inhaled corticosteroids, a history of psychiatric disease or psychosocial problems, poor adherence with asthma medications and/or poor adherence with (or lack of) a written asthma action plan, food allergy in a patient with asthma. Preventable factors have been identified in the majority of asthma deaths. Inadequate education of patients on recognising risk and the appropriate action needed when asthma control is poor, deficiencies in the accuracy and timing of asthma diagnosis, inadequate classification of severity and treatment, seem to play a part in the majority of asthma deaths. Improvements in management, epitomized by the use of guided self-management systems of care may be the key goals in reducing asthma mortality worldwide.

The aim of the study was to evaluate CXCL4 levels in undifferentiated connective tissue disease at risk for SSc (UCTD-SSc-risk) and confirm its increase and investigate its prognostic value. Serum CXCL4 levels were measured in 45 patients and 24 controls. CXCL4 was significantly higher in UCTD-SSc-risk patients than in controls. It resulted higher in patients with a shorter disease duration and in those lacking capillaroscopic alterations. We confirm that CXCL4 levels are increased in UCTD-risk-SSc patients. Further studies are needed to investigate the role of CXCL4 assessment in UCTD-risk-SSc.

Background: Sarcoidosis is a systemic granulomatous disease of unknown origin, characterized by the formation of granulomas without central necrosis. Each organ and tissue can be affected by the disease, but in most cases mainly the lungs and mediastinal lymph nodes but also skin, heart, eyes and joints are involved, the latter are mainly the metacarpophalangeal joints and bone lesions are often associated with involvement of the overlying skin. The diagnosis is often of exclusion, based on clinical and radiological suspicion, and should be confirmed by biopsy, although in each case it is necessary to exclude other possible causes of granulomatosis, including infections by mycobacteria. Here it is reported a case of particularly aggressive sarcoidosis with primitive involvement of the small joints of the hands and feet, and mediastinal lymph nodes. Case presentation: The subject, a man, 60 years old, born in Morocco but living in Italy for many years, presented important involvement of bone structures and soft periarticular tissue, and was affected by the formation of granulomas without “caseum necrosis”. The painful symptoms and the skin ulceration had led to surgical amputation of the distal phalanges of most fingers of his hands and feet, but with subsequent resurgence of lesions in acral locations after surgery. The PET/CT scan showed an amount of radiotracer in mediastinal lymph nodes, while the lymph nodes sampled by TBNA were normal and the CD4/CD8 ratio was less than 3 in the bronchoalveolar lavage. We ruled out any possible infectious cause, including mycobacterial infection (both tubercular and atypical), so the patient was treated with systemic corticosteroids, with an excellent clinical and radiological response. Conclusions: Such a case shows how the disease can have variable expressions, without primitive lung involvement; therefore, it should be necessary to consider any possible, unpredictable localization of the disease.

Aclidinium is a twice-daily long-acting muscarinic receptor antagonist (LAMA) with an interesting pharmacological profile. Recent evidence indicates that this LAMA, in addition to causing a significant improvement in lung function and other important supportive outcomes, such as health related quality of life, dyspnea and nighttime/early morning symptoms in patients suffering from COPD, is also able to significantly reduce the rate of exacerbations of any severity, is extremely effective in controlling the COPD symptoms, is able to reduce lung hyperinflation, and has an excellent cardiovascular safety profile. Consequently, aclidinium should be considered a first-line approach at least for the symptomatic treatment of COPD although there are still few head-to-head studies comparing this LAMA with other bronchodilators. In any case, aclidinium can be taken into account in the treatment of different COPD phenotypes (emphysema, chronic bronchitis, exacerbators and patients with overlap COPD asthma).

Screening of latent infection by Mycobacterium tuberculosis (LTBI) and treatment of positive subjects is the key point in the prevention of TB; such a strategy should be performed mainly among individuals with risk of progression. Progression from LTBI to active TB is highest both in recent contacts of patients with active TB, and in immunocompromised subjects. Therefore, LTBI could either be considered a permanent host defence or, seen from the opposite point of view, it could represent a long-lasting threat if the efficiency of the immune system declines over a lifetime. Interferon gamma release assays (IGRAs) show better sensitivity and specificity than the Mantoux test.

The clinical course in idiopathic pulmonary fibrosis (IPF) is highly heterogeneous, with some patients having a slow progression and others an accelerated clinical and functional decline. This study aims to clinically characterize the type of progression in IPF and to investigate the pathological basis that might account for the observed differences in disease behavior. Clinical and functional data were analyzed in 73 IPF patients, followed long-time as candidates for lung transplantation. The forced vital capacity (FVC) change/year (< or ≥10% predicted) was used to define "slow" or "rapid" disease progression. Pathological abnormalities were quantified in the explanted lung of 41 out of 73 patients undergoing lung transplantation. At diagnosis, slow progressors (n = 48) showed longer duration of symptoms and lower FVC than rapid progressors (n = 25). Eleven slow and 3 rapid progressors developed an acute exacerbation (AE) during follow-up. Quantitative lung pathology showed a severe innate and adaptive inflammatory infiltrate in rapid progressors, markedly increased compared to slow progressors and similar to that observed in patients experiencing AE. The extent of inflammation was correlated with the yearly FVC decline (r = 0.52, p = 0.005). In conclusion an innate and adaptive inflammation appears to be a prominent feature in the lung of patients with IPF and could contribute to determining of the rate of disease progression.

Chronic Obstructive Pulmonary Disease (COPD) is a chronic and progressive lung disease characterized by irreversible airflow obstruction, airway inflammation, oxidative stress and, often, mucus hypersecretion. The aim of this study is to determine if carbocisteine, a mucolytic and antioxidant agent, administered daily for 12 months, can reduce exacerbation frequency in COPD patients.This observational study was conducted in Naples (population approximately 1000,000), Italy. It included 85 out-patients (mean age of 67.8 ± 8.6 years) followed by Clinic of Respiratory Diseases of the University Federico II. Every patient underwent spirometry demonstrating airflow obstruction not fully reversible according to ERS/ATS criteria for COPD diagnosis (Tiffenau index less than 70% after administration of salbutamol, a beta2 agonist drug). Patients enrolled had diagnosed COPD since 2 years and suffered at least one exacerbation in the previous year. None of the patients had been treated with carbocisteine or other mucolytic agent for a longer period of time than 7 days and no more than 4 times in the previous year to the enrollment. All of them assumed daily 2.7 g of carbocisteine lysine salt for a year in addition to their basic therapy.The comparison of exacerbation frequency between the previous year (T0) and the end of study treatment (T12), documents a statistically significant reduction of exacerbations(number of exacerbations at T0: 2 [1,3] vs number of exacerbations at T12: 1 [1,2]; p 0.001).Quality of life was also reported and showed a statistically significant improvement at the end of the study (p 0.001).We did not find correlation between reducing exacerbation frequency and exposure to cigarette smoking, passive smoking exposure in childhood, the use of inhaled steroids, the level of education of our patients and the GOLD stadium.Daily administration of a mucolytic drug such as carbocisteine for prolonged periods in addition to the bronchodilator therapy can be considered a good strategy for reducing exacerbation frequency in COPD.

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. In 2010, the British Thoracic Society (BTS) published guidelines on the management of bronchiectasis in adults, along with specific quality standards. 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. 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.

International audience; The major changes to our world are those involving the atmosphere and the climate, including global warming induced by anthropogenic factors, with impact on the biosphere and human environment. Studies on the effects of climate changes on respiratory allergy are still lacking and current knowledge is provided by epidemiological and experimental studies on the relationship between allergic respiratory diseases, asthma and environmental factors, like meteorological variables, airborne allergens and air pollution. Epidemiologic studies have demonstrated that urbanization, high levels of vehicle emissions and westernized lifestyle are correlated with an increased frequency of respiratory allergy, mainly in people who live in urban areas in comparison with people living in rural areas. However, it is not easy to evaluate the impact of climate changes and air pollution on the prevalence of asthma in general and on the timing of asthma exacerbations, although the global rise in asthma prevalence and severity could be also considered an effect of air pollution and climate changes. Since airborne allergens and air pollutants are frequently increased contemporaneously in the atmosphere, enhanced IgE-mediated response to aeroallergens and enhanced airway inflammation could account for the increasing frequency of respiratory allergy and asthma in atopic subjects in the last five decades. Pollen allergy is frequently used to study the interrelationship between air pollution and respiratory allergic diseases such as rhinitis and bronchial asthma. Climatic factors (temperature, wind speed, humidity, thunderstorms, etc) can affect both components (biological and chemical) of this interaction. Scientific societies should be involved in advocacy activities, such as those realized by the Global Alliance against chronic Respiratory Diseases (GARD).

AIM: To determine which timing of therapy with formoterol (FOR) and/or tiotropium (TIO) shows the greater and more continuous functional improvement during 24 h in patients with moderate to severe COPD. METHODS: In this randomised, blind, crossover study 80 patients with stable COPD (40 moderate and 40 severe) received 5 different bronchodilator 30-day treatments in a random order. Treatments (Tr) were: Tr1: TIO 18 microg once-daily (8 am); Tr2: TIO 18 microg (8 am) + FOR 12 microg (8 pm); Tr3: FOR 12 microg twice-daily (8 am and 8 pm); Tr4: TIO 18 microg (8 am) + FOR 12 microg twice-daily (8 am and 8 pm); Tr5: FOR 12 microg twice-daily (8 am and 8 pm) + TIO 18 microg (8 pm). Spirometries were performed during 24 h (13 steps) on Day1 and Day30. End-points were: gain of FEV(1) (DeltaFEV(1)) from baseline of the Day1 and Day30, AUC (Area Under Curve), Dyspnoea Index, and as-needed use of salbutamol. RESULTS: Sixty-eight patients completed all treatments. The greater and continuous daily functional improvement was showed during Tr4 and Tr5 (Day1 +135.8 mL and +119.1 mL; Day30 +160.2 mL, and +160.5 mL, respectively). Daily means of DeltaFEV(1) were significantly different between single-drug treatments and combination therapy. Dyspnoea was greater in single-drug treatments. Less use of rescue salbutamol was reported in Tr4 (0.80 puffs/die) and Tr5 (0.71 puffs/die). CONCLUSIONS: In patients with moderate to severe COPD, combination therapy with tiotropium administered in the morning (Tr4) was the most effective; in patients with prevailing night-symptoms, treatment with tiotropium in the evening (Tr5) reduced symptoms and use of salbutamol. Tr5 showed less variability of FEV(1) during the 24 h (CV=0.256). These results are relevant for opening new ways in clinical practice.

Understanding variability in the response to asthma medications is essential to ensure appropriate prescribing. Given that there are increased asthma treatment failures observed in ethnic minorities receiving asthma therapeutics, it is fundamental to understand the factors related to ethnicity that can modify the response to asthma therapy.Race/ethnicity is an important determinant of drug response and therefore contributes to interindividual variability. It is generally recognized that its effects on drug response are determined by both genetic and environmental factors to a varying extent, depending on the ethnic groups and probe drugs studied. Also, adherence to therapy can influence pharmacological response to asthma therapeutics.Health-care professionals might never use the treatment in their patients irrespective of their ethnicity and thus inadvertently increase ethnic health inequality. However, our understanding of whether and/or how ethnicity influences pharmacological response to asthma therapeutics is still very scarce. A holistic, integrative systems biology approach that combines large-scale molecular profiling traits (e.g., transcriptomic, proteomic, metabolomic traits) and genetic variants could help to personalize the treatment of asthmatic patients regardless of race/ethnicity.

Background In this retrospective Italian study, which involved all major national interstitial lung diseases centers, we evaluated the effect of pirfenidone on disease progression in patients with IPF. Methods We retrospectively studied 128 patients diagnosed with mild, moderate or severe IPF, and the decline in lung function monitored during the one-year treatment with pirfenidone was compared with the decline measured during the one-year pre-treatment period. Results At baseline (first pirfenidone prescription), the mean percentage forced vital capacity (FVC) was 75% (35-143%) of predicted, and the mean percentage diffuse lung capacity (DLCO) was 47% (17-120%) of predicted. Forty-eight patients (37.5%) had mild disease (GAP index stage I), 64 patients (50%) had moderate IPF (stage II), and 8 patients (6.3%) had severe disease (stage III). In the whole population, pirfenidone attenuated the decline in FVC (p = 0.065), but did not influence the decline in DLCO (p = 0.355) in comparison to the pre-treatment period. Stratification of patients into mild and severe disease groups based on %FVC level at baseline (>75% and ≤75%) revealed that attenuation of decline in FVC (p = 0.002) was more pronounced in second group of patients. Stratification of patients according to GAP index at baseline (stage I vs. II/III) also revealed that attenuation of decline in lung function was more pronounced in patients with more severe disease. Conclusions In this national experience, pirfenidone reduced the rate of annual FVC decline (p = 0.065). Since pirfenidone provided significant treatment benefit for patients with moderate-severe disease, our results suggest that the drug may also be effective in patients with more advanced disease.
