Sex bias in diagnostic delay in bronchiectasis: An analysis of the Spanish Historical Registry of Bronchiectasis.

Diagnostic delay is common in most respiratory diseases, particularly in bronchiectasis. However, sex bias in diagnostic delay has not been studied to date. OBJECTIVE: Assessment of diagnostic delay in bronchiectasis by sex. METHODS: The Spanish Historical Registry of Bronchiectasis recruited adults diagnosed with bronchiectasis from 2002 to 2011 in 36 centres in Spain. From a total of 2113 patients registered we studied 2099, of whom 1125 (53.6%) were women. RESULTS: No differences were found for sex or age (61.0 ± 20.6, p = 0.88) or for localization of bronchiectasis ( p = 0.31). Bronchiectasis of unknown aetiology and secondary to asthma, childhood infections and tuberculosis was more common in women (all ps < 0.05). More men than women were chronic obstructive pulmonary disease-related bronchiectasis and colonized by Haemophilus influenzae ( p < 0.001 for both). Onset of symptoms was earlier in women. The diagnostic delay for women with bronchiectasis was 2.1 years more than for men ( p = 0.001). DISCUSSION: We recorded a substantial delay in the diagnosis of bronchiectasis. This delay was significantly longer in women than in men (>2 years). Independent factors associated with this sex bias were age at onset of symptoms, smoking history, daily expectoration and reduced lung function.

[The future of inhaled antibiotic therapy. New products]. / El futuro de la antibioterapia inhalada. Nuevos productos.

Inhaled antibiotics have been used for more than 30 years to treat bronchial colonization or infection, especially in patients with cystic fibrosis and chronic bronchial infection with Pseudomonas. However, major progress in this field has only been made in the last 10 years: the beneficial effects in this indication have been confirmed by scientific evidence, the number of clinical trials has considerably increased, inhaled antibiotic formulations have appeared, administration systems have improved and their use has been broadened to include other infections. The speed of research indicates that major advances will be made in the indications and arsenal of inhaled antibiotics, as well as in the effectiveness of administration systems in the next 10 years. A desirable aim in the immediate future would be to demonstrate the efficacy of inhaled antibiotics in the treatment of any chronic bronchial infection, irrespective of the causative microorganism or the underlying disease and even in the absence of bronchiectasis. The antibiotic effect is related to the concentration achieved in the site of infection. Antibiotic administration through the inhaled route is subject to many variables: the dose administered, the dose that reaches the site of infection, the type of nebulizer used and the patient's characteristics. Many features of the pharmacokinetics of this route remain unknown and, because of its complexity, it should be prescribed and monitored by specialist physicians to avoid underdosing, which could lead to bacterial resistance.

[Respiratory disease registries in Spain: fundamentals and organization]. / Registros de enfermedades respiratorias en España: fundamentos y organización.

This present paper describes the general characteristics, objectives and organizational aspects of the respiratory disease registries in Spain with the aim to report their activities and increase their diffusion. The document compiles information on the following registries: the Spanish Registry of Patients with Alpha-1 Antitrypsin Deficiency, Spanish Registry of Bronchiectasis, International Registry of Thromboembolic Disease, Spanish Registry of Occupational Diseases, Spanish Registry of Pulmonary Artery Hypertension, Registry of Pleural Mesothelioma, Spanish Registry of Tuberculosis and Spanish Multi-center Study of Neuroendocrine Pulmonary Tumors. Our paper provides information on each of the registries cited. Each registry has compiled specific clinical information providing data in real situations, and completes the results obtained from clinical assays. Said information has been published both in national as well as international publications and has lead to the creation of various guidelines. Therefore, the activities of the professionals involved in the registries have spread the knowledge about the diseases studied, promoting the exchange of information among workgroups.

[Bronchiectasis treatment in adults]. / Tratamiento de las bronquiectasias en el adulto.

Bronchiectasis is characterized by the dilation and progressive destruction of the bronchial wall. Its actual importance lies in two points: the increased number of diagnoses due to increased chronic diseases and the use of new diagnostic tools, and its negative impact on quality of life and lung function of patients and the negative prognosis of the causative disease. In practical terms, the treatment of bronchiectasis in adults is based on eight basic pillars: treatment of the etiology if it is known, treatment of the bronchial colonization or infection by potentially pathogenic microorganisms including Pseudomonas aeruginosa (inhaled or systemic antibiotics), treatment of bronchial secretions (chest physiotherapy and mucolytics), treatment of bronchial inflammation (inhaled steroids and macrolides) and hyperresponsiveness (inhaled steroids and bronchodilators), treatment of systemic manifestations (malnutrition), treatment of exacerbations (oral antibiotics, removing secretions and the associated bronchospasm), treatment of complications (hemoptysis, respiratory failure and mucous plugs), and finally, surgical treatment (lung transplantation or resection surgery).

[Nocardiosis and bronchiectasis. An uncommon association?]. / Nocardiosis y bronquiectasias. 'Una asociación infrecuente?

OBJECTIVE: Nocardiosis is difficult to diagnose and infrequently associated with bronchiectasis or cystic fibrosis. This study analyzes the clinical and microbiological characteristics of 40 patients in whom microorganisms belonging to the Nocardia asteroides complex were isolated. METHODS: We studied 27 males and 13 females, with a mean age of 45 years (8-82). Nocardia spp. were isolated in 129 samples. Cultures were performed with conventional methods; additionally, when branching Gram-positive bacilli were visualized on microscopic examination, modified BCYE-alpha (m) medium was used. RESULTS: In 77.5% of the cases, investigation for Nocardia spp. was based on microscopy findings, in six patients it was a fortuitous finding in BCYE-alpha (m) medium, and in only three patients nocardiosis was clinically suspected. Twenty-five patients had nocardiosis (5 disseminated infection and 20 lung infection) and the remaining 15 were colonized. The most frequent risk factor in the infections, whether disseminated or not, was systemic glucocorticoid use (P 5 .001). The most frequent underlying pathology was bronchiectasis (80%), associated or not with cystic fibrosis. There were seven deaths and two patients had neurological sequelae. CONCLUSIONS: Bronchiectasis was an important risk factor for colonization by Nocardia spp. (P 5 0.01) in all the patients studied, and for infection (P 5 0.05) in patients without cystic fibrosis. The use of BCYE-alpha (m) medium in processing respiratory secretions highly facilitated the isolation of Nocardia spp.
