Abstract
The Finnish Medical Society Duodecim initiated and managed the update of the Finnish national guideline for Chronic Obstructive Pulmonary Disease (COPD). The Finnish COPD guideline was revised in order to acknowledge the progress in diagnosis and management of COPD. This Finnish COPD guideline in English language is a part of the original guideline and focuses on the diagnosis, assessment and pharmacotherapy of stable COPD. It is intended to be used mainly in primary health care but not forgetting respiratory specialists and other health care workers. The new recommendations and statements are based on the best evidence available from the medical literature, other published national guidelines and the GOLD (Global Initiative for Chronic Obstructive Lung Disease) report. This guideline introduces the diagnostic approach, differential diagnostics towards asthma, assessment and treatment strategy to control symptoms and to prevent exacerbations. The pharmacotherapy is based on the symptoms and a clinical phenotype of the individual patient. The guideline defines three clinically relevant phenotypes including the low and high exacerbation risk phenotypes and the neglected asthma-COPD overlap syndrome (ACOS). These clinical phenotypes can help clinicians to identify patients that respond to specific pharmacological interventions. For the low exacerbation risk phenotype, pharmacotherapy with short-acting β2 -agonists (salbutamol, terbutaline) or anticholinergics (ipratropium) or their combination (fenoterol - ipratropium) is recommended in patients with less symptoms. If short-acting bronchodilators are not enough to control symptoms, a long-acting β2 -agonist (formoterol, indacaterol, olodaterol or salmeterol) or a long-acting anticholinergic (muscarinic receptor antagonists; aclidinium, glycopyrronium, tiotropium, umeclidinium) or their combination is recommended. For the high exacerbation risk phenotype, pharmacotherapy with a long-acting anticholinergic or a fixed combination of an inhaled glucocorticoid and a long-acting β2 -agonist (budesonide - formoterol, beclomethasone dipropionate - formoterol, fluticasone propionate -salmeterol or fluticasone furoate - vilanterol) is recommended as a first choice. Other treatment options for this phenotype include combination of long-acting bronchodilators given from separate inhalers or as a fixed combination (glycopyrronium - indacaterol or umeclidinium - vilanterol) or a triple combination of an inhaled glucocorticoid, a long-acting β2 -agonist and a long-acting anticholinergic. If the patient has severe to very severe COPD (FEV1 < 50% predicted), chronic bronchitis and frequent exacerbations despite long-acting bronchodilators, the pharmacotherapy may include also roflumilast. ACOS is a phenotype of COPD in which there are features that comply with both asthma and COPD. Patients belonging to this phenotype have usually been excluded from studies evaluating the effects of drugs both in asthma and COPD. Thus, evidence-based recommendation of treatment cannot be given. The treatment should cover both diseases. Generally, the therapy should include at least inhaled glucocorticoids (beclomethasone dipropionate, budesonide, ciclesonide, fluticasone furoate, fluticasone propionate or mometasone) combined with a long-acting bronchodilator (β2 -agonist or anticholinergic or both).

Nanomedicine and therapy of lung diseases.

Nanomedicine and therapy of lung diseases.

Einstein (Sao Paulo). 2014 Dec 16;0:0

Authors: Garcia FD

Abstract
The use of nanotechnology has significantly increased in different fields of science, including the development of drug delivery systems. Currently, the most modern pharmaceutical nanocarriers, such as liposomes, micelles, nanoemulsions and polymeric nanoparticles, demonstrate extremely useful properties from the point of view of drug therapy. In this context, the development of nanocarriers for pulmonary application has been much debated by the scientific community in recent decades. Although research on the use of nanoparticles for pulmonary application are still in the initial phase, the studies conducted to date suggest that the development of drug delivery systems for systemic or local treatment of diseases that affect the respiratory system may be promising.

Abstract
SETTING: Frequent exacerbation is an important phenotype in chronic obstructive pulmonary disease (COPD), while emphysema is associated with many comorbidities and lung function decline.
OBJECTIVE: To investigate unique features of frequent exacerbators and test the hypothesis that emphysematous phenotype is associated with frequent exacerbations of COPD.
METHODS: A total of 380 COPD patients were recruited from 16 hospitals in Korea from June 2005 to April 2012 for analysis. We searched for independent predictors of frequent exacerbators in comparison with non-exacerbators.
RESULTS: As the severity of emphysema increased, forced expiratory volume in 1 s (FEV1), and FEV1/FVC (forced volume capacity) worsened; hyperinflationary features characterised by higher total lung capacity (TLC) were observed (P < 0.05). Frequent exacerbators had lower body mass index (BMI), higher St George's Respiratory Questionnaire (SGRQ) scores, higher residual volume (RV)/TLC, more severe airflow limitation (lower FEV1 and FEV1/FVC), lower carbon monoxide diffusion capacity, lower serum protein levels and a higher emphysema index than non-exacerbators (P < 0.05). In multivariate analysis, frequent exacerbators were independently associated with a higher emphysema index, lower serum protein levels and higher RV/TLC (P < 0.05).
CONCLUSION: Our data show that the severity of emphysema, severe static hyperinflation and serum lower protein levels are independent predictors of frequent exacerbations in COPD patients.

Abstract
SETTING: A novel effective treatment is necessary for severe asthma.
OBJECTIVE: To review clinical trials examining the role of tiotropium in patients with poorly controlled asthma despite inhaled corticosteroid use with or without long-acting β2-agonists.
DESIGN: A computerised search of electronic databases (Medline, EMBASE and Cochrane Central Register) was performed. Randomised controlled trials of at least a 4-week treatment duration with findings published in English were included.
RESULTS: Five studies involving 1635 patients were analysed. Compared with a placebo or a double dose of inhaled corticosteroids, the addition of tiotropium increased mean trough and peak forced expiratory volume in 1 second by 97 ml (95%CI 71-122) and 103 ml (95%CI 42-163), respectively. The mean differences in morning peak expiratory flow were 19.2 l/min (95%CI 11.8-26.6). Tiotropium also reduced the risk of severe acute exacerbation (OR 0.73, 95%CI 0.56-0.96) and improved Asthma Quality-of-Life Questionnaire score significantly by 0.10 (95%CI 0.04-0.16). There were no differences in serious adverse events.
CONCLUSION: The addition of tiotropium may be beneficial for patients with poorly controlled asthma, although exacerbation or safety issues should be clarified in long-term trials before its wide use in asthma.

Evaluating the role of primary care physicians in the treatment of latent tuberculosis: a population study.

Evaluating the role of primary care physicians in the treatment of latent tuberculosis: a population study.

Int J Tuberc Lung Dis. 2014 Dec;18(12):1449-54

Abstract
SETTING: Latent tuberculous infection (LTBI) remains a significant source of new active tuberculosis cases. Recent guidelines encourage primary care physicians to prescribe LTBI treatment; however, there have been no investigations into the impact on treatment completion.
OBJECTIVE: To estimate LTBI treatment initiation and completion rates by primary care physicians.
DESIGN: A historical cohort study was conducted with Quebec residents dispensed isoniazid (INH) between 1 January 1998 and 31 December 2005. Information was obtained from administrative health insurance data. Regression modeling was used to estimate the association of completion rates with prescribing physician specialty, after adjustment for initial health status and other patient characteristics.
RESULTS: A total of 14 753 people were dispensed INH for LTBI treatment. Primary care physicians initiated 3863 (26%) treatments. This proportion decreased from 28.7% in 1998 to 21.1% in 2005. Patients initiated on treatment by primary care physicians were less likely to complete treatment (OR 0.79, 95%CI 0.72-0.86). Only 5977 (40.5%) patients completed treatment; the average treatment duration of the primary care physician group was 11 days less (P < 0.0001).
CONCLUSION: Primary care physicians initiated a substantial number of LTBI treatments, but less than half of patients completed treatment regardless of the physician specialty. Primary care physicians should be supported to enhance treatment completion.
