[Bronchiectasis not due to cystic fibrosis]. / Bronquiectasias no debidas a fibrosis quística.

Bronchiectasis is a clinical-radiological condition composed of irreversible bronchial dilation due to inflammation and infection of the airways, which causes respiratory symptoms, usually productive cough and infectious exacerbations. Bronchiectasis can have multiple causes, both pulmonary and extrapulmonary, and its clinical presentation is very heterogenous. Its prevalence is unknown, although up to 35-50% of severe COPD and 25% of severe asthma present them, so their underdiagnosis is evident. Chronic bacterial bronchial infection is common, and Pseudomonas aeruginosa is the pathogen that has been found to imply a worse prognosis. Treatment of bronchiectasis has three fundamental characteristics: it must be multidisciplinary (involvement of several specialties), pyramidal (from primary care to the most specialized units) and multidimensional (management of all aspects that make up the disease).

Effectiveness and Safety of Inhaled Antibiotics in Patients With Chronic Obstructive Pulmonary Disease. A Multicentre Observational Study.

BACKGROUND: We aimed to describe the effectiveness and safety of inhaled antibiotics in chronic obstructive pulmonary disease (COPD) patients, as well as the patient profile in which they are usually prescribed and the patient groups that can most benefit from this treatment. METHODS: Multicentre retrospective observational cohort study in COPD patients who had received ≥1 dose of inhaled antibiotics in the last 5 years. Clinical data from the two years prior to and subsequent to the start of the treatment were compared. PRIMARY OUTCOME: COPD exacerbations. SECONDARY OUTCOMES: side effects, symptomatology (sputum purulence, dyspnoea), microbiological profile and pathogen eradication. RESULTS: Of 693 COPD patients analyzed (aged 74.1; 86.3% men; mean FEV1=43.7%), 71.7% had bronchiectasis and 46.6% presented chronic bronchial infection (CBI) by Pseudomonas aeruginosa (PA). After 1 year of treatment with inhaled antibiotics, there was a significant decrease in the number of exacerbations (-33.3%; P<.001), hospital admissions (-33.3%; P<.001) and hospitalization days (-26.2%; P=.003). We found no difference in effectiveness between patients with or without associated bronchiectasis. Positive patient outcomes were more pronounced in PA-eradicated patients. We found a significant reduction in daily expectoration (-33.1%; P=.024), mucopurulent/purulent sputum (-53.9%; P<.001), isolation of any potentially pathogenic microorganisms (PPM) (-16.7%; P<.001), CBI by any PPM (-37.4%; P<.001) and CBI by PA (-49.8%; P<.001). CBI by any PPM and ≥three previous exacerbations were associated with a better treatment response. 25.4% of patients presented non-severe side-effects, the most frequent of these being bronchospasm (10.5%), dyspnoea (8.8%) and cough (1.7%). CONCLUSIONS: In COPD patients with multiple exacerbations and/or CBI by any PPM (especially PA), inhaled antibiotics appear to be an effective and safe treatment, regardless of the presence of bronchiectasis.

RIBRON: The spanish Online Bronchiectasis Registry. Characterization of the First 1912 Patients. / RIBRON: el registro español informatizado de bronquiectasias. Caracterización de los primeros 1.912 pacientes.

INTRODUCTION: The SEPAR Spanish Bronchiectasis Registry (RIBRON) began as a platform for the collection of longitudinal data on patients with this disease. The objective of this study is to describe its operation and to analyze the characteristics of bronchiectasis patients according to sex. METHODS: A total of 1912 adult patients diagnosed with bronchiectasis in 43 centers were included between February 2015 and 2019. All patients had complete data consisting of at least 79 basic required variables, controlled by an external audit. RESULTS: Mean age was 67.6 (15.2) years; 63.9% were women. The most common symptom was productive cough (78.3%) which was mucopurulent-purulent in 45.9% of cases. The most common etiology was post-infectious (40.4%), while 18.5% were idiopathic. Pseudomonas aeruginosa was the most frequently isolated microorganism (40.4%), of which 25.6% were associated with chronic infection. The annual number of mild-to-moderate/severe exacerbations was 1.62 (1.9)/0.59 (1.3). Half of the patients (50%) presented with airflow obstruction (17% severe). The most frequent radiological localization was lower lobes. The average FACED/E-FACED/BSI values were 2.06 (1.7)/2.67 (2.2)/7.8 (4.5), respectively. Overall, 66.7% of patients were taking inhaled corticosteroids, 19.2% macrolides, and 19.5% inhaled antibiotics. Women presented a less severe profile than men in clinical and functional terms, and a similar infectious, radiological and therapeutic profile. CONCLUSIONS: RIBRON represents an excellent map of the characteristics of bronchiectasis in our country. Two thirds of patients are women who presented lower disease severity as a specific characteristic.

Consensus Document on the Diagnosis and Treatment of Chronic Bronchial Infection in Chronic Obstructive Pulmonary Disease. / Documento de consenso sobre el diagnóstico y tratamiento de la infección bronquial crónica en la enfermedad pulmonar obstructiva crónica.

Although the chronic presence of microorganisms in the airways of patients with stable chronic obstructive pulmonary disease (COPD) confers a poor outcome, no recommendations have been established in disease management guidelines on how to diagnose and treat these cases. In order to guide professionals, the Spanish Society of Pulmonology and Thoracic Surgery (SEPAR) has prepared a document which aims to answer questions on the clinical management of COPD patients in whom microorganisms are occasionally or habitually isolated. Since the available scientific evidence is too heterogeneous to use in the creation of a clinical practice guideline, we have drawn up a document based on existing scientific literature and clinical experience, addressing the definition of different clinical situations and their diagnosis and management. The text was drawn up by consensus and approved by a large group of respiratory medicine experts with extensive clinical and scientific experience in the field, and has been endorsed by the SEPAR Scientific Committee.

Spanish Guidelines on the Evaluation and Diagnosis of Bronchiectasis in Adults. / Normativa sobre la valoración y el diagnóstico de las bronquiectasias en el adulto.

In 2008, the Spanish Society of Pulmonology (SEPAR) published the first guidelines in the world on the diagnosis and treatment of bronchiectasis. Almost 10 years later, considerable scientific advances have been made in both the treatment and the evaluation and diagnosis of this disease, and the original guidelines have been updated to include the latest scientific knowledge on bronchiectasis. These new recommendations have been drafted following a strict methodological process designed to ensure the quality of content, and are linked to a large amount of online information that includes a wealth of references. These guidelines cover aspects ranging from a consensual definition of bronchiectasis to an evaluation of the natural course and prognosis of the disease. The topics of greatest interest and some new areas are addressed, including epidemiology and economic costs of bronchiectasis, pathophysiological aspects, the causes (placing particular emphasis on the relationship with other airway diseases such as chronic obstructive pulmonary disease and asthma), clinical and functional aspects, measurement of quality of life, radiological diagnosis and assessment, diagnostic algorithms, microbiological aspects (including the definition of key concepts, such as bacterial eradication or chronic bronchial infection), and the evaluation of severity and disease prognosis using recently published multidimensional tools.

Almost 10 years later, considerable scientific advances have been made in both the treatment and the evaluation and diagnosis of this disease, and the original guidelines have been updated to include the latest therapies available for bronchiectasis. These new recommendations have been drafted following a strict methodological process designed to ensure quality of content, and are linked to a large amount of online information that includes a wealth of references. The guidelines are focused on the treatment of bronchiectasis from both a multidisciplinary perspective, including specialty areas and the different healthcare levels involved, and a multidimensional perspective, including a comprehensive overview of the specific aspects of the disease. A series of recommendations have been drawn up, based on an in-depth review of the evidence for treatment of the underlying etiology, the bronchial infection in its different forms of presentation using existing therapies, bronchial inflammation, and airflow obstruction. Nutritional aspects, management of secretions, muscle training, management of complications and comorbidities, infection prophylaxis, patient education, home care, surgery, exacerbations, and patient follow-up are addressed.

Spanish consensus on the prevention and treatment of Pseudomonas aeruginosa bronchial infections in cystic fibrosis patients.

Pseudomonas aeruginosa is the main pathogen in bronchopulmonary infections in cystic fibrosis (CF) patients. It can only be eradicated at early infection stages while reduction of its bacterial load is the therapeutic goal during chronic infection or exacerbations. Neonatal screening and pharmacokinetic/pharmacodynamic knowledge has modified the management of CF-patients. A culture based microbiological follow-up should be performed in patients with no infection with P.aeruginosa. At initial infection, inhaled colistin (0,5-2MU/tid), tobramycin (300mg/bid) or aztreonam (75mg/tid) with or without oral ciprofloxacin (15-20mg/kg/bid, 2-3weeks) are recommended. In chronic infections, treatment is based on continuous administration of colistin or with a 28-day on-off regimen with tobramycin or aztreonam. During mild-moderate exacerbations oral ciprofloxacin (2-3weeks) can be administered while serious exacerbations must be treated with intravenous combination therapy (beta-lactam with an aminoglycoside or a fluoroquinolone). Future studies will support antibiotic rotation and/or new combination therapies. Epidemiological measures are also recommended to avoid new P.aeruginosa infections and "patient-to-patient transmission" of this pathogen.
