RATIONALE: Classical interpretation of cystic fibrosis (CF) lung disease pathogenesis suggests that infection initiates disease progression, leading to an exuberant inflammatory response, excessive mucus, and ultimately bronchiectasis. While symptomatic antibiotic treatment controls lung infections early in disease, life-long bacterial residence typically ensues. Processes that control the establishment of persistent bacteria in the CF lung, and the contribution of non-infectious components to disease pathogenesis, are poorly understood...

Keeping airways clear of mucus by airway clearance techniques seems essential in bronchiectasis treatment, although no placebo-controlled trials or any studies lasting longer than 3 months have been conducted. We evaluate the efficacy of the ELTGOL (slow expiration with the glottis opened in the lateral posture) technique over a 1-year period in bronchiectasis patients with chronic expectoration in a randomised placebo-controlled trial.Patients were randomised to perform the ELTGOL technique (n=22) or placebo exercises (n=22) twice-daily (ClinicalTrials...

The most common delayed complication of sulfur mustard (SM) poisoning has been observed in the respiratory tracts. It was thus aimed to investigate the delayed respiratory complications in SM-exposed patients around 25 years before the study. Forty-three veterans with more than 25% disability of due to SM poisoning were investigated. Clinical examinations as well as pulmonary function test (PFT) were performed. High-resolution computed tomography (HRCT) of the lungs was done as clinically indicated. Triad of chronic cough, dyspnea, and expectoration were the most common symptoms that were recorded in 88...

Vitamin D deficiency is believed to a pathogenetic factor in patients with allergic bronchopulmonary aspergillosis (ABPA) and cystic fibrosis. Whether vitamin D deficiency is also prevalent in ABPA complicating asthma, remains unknown. Herein, we evaluate vitamin D levels in asthmatic patients with and without ABPA. In a prospective study, plasma vitamin D (25[OH]D) levels were measured in consecutive subjects with asthma (n=75), ABPA (n=158) and healthy volunteers (n=50). Vitamin D levels <20 ng/mL were considered as vitamin D deficiency...

INTRODUCTION: Bronchiectasis (BC) is a multidimensional and etiologically diverse disease and, therefore, no single parameter can be used to determine its overall severity and prognosis. In this regard, two different validated scores are currently used to assess the severity of non-cystic fibrosis bronchiectasis (NCFB): the FACED score and the Bronchiectasis Severity Index (BSI). OBJECTIVE: To describe the etiology of NCFB and compare the results of the assessment of NCFB severity obtained via FACED and BSI scores...

Bronchiectasis is a clinically important, but poorly understood, pulmonary condition characterized by dilated and thick-walled bronchi. Bronchiectasis remains a significant cause of morbidity and mortality around the world. Targeted effort to early high-resolution computed tomography diagnosis and detailed confirmation of causation are in the spotlight of respiratory physicians in the developed countries. The risk population consists of subjects with persistent and/or productive cough, where another clear diagnosis has not been performed...

Although the spectrum of fungal pathology has been studied extensively in immunosuppressed patients, little is known about the epidemiology, risk factors, and management of fungal infections in chronic pulmonary diseases like bronchiectasis. In bronchiectasis patients, deteriorated mucociliary clearance-generally due to prior colonization by bacterial pathogens-and thick mucosity propitiate, the persistence of fungal spores in the respiratory tract. The most prevalent fungi in these patients are Candida albicans and Aspergillus fumigatus; these are almost always isolated with bacterial pathogens like Haemophillus influenzae and Pseudomonas aeruginosa, making very difficult to define their clinical significance...

Aztreonam, a broad-spectrum monobactam, is typically reserved for multidrug resistant (MDR) infections. Pharmacokinetic (PK) data to guide dosing in children, however, are limited to healthy volunteers or nonintensive care unit (ICU) patients. Impaired antibiotic delivery into tissue remains a major concern and may explain the high morbidity and mortality associated with MDR infections. Therefore, evaluating the PK changes in pediatric ICU patients is necessary to elucidate the most appropriate antimicrobial regimen...

BACKGROUND: Staphylococcus aureus (S. aureus) may be related to more rapid progression of cystic fibrosis (CF) lung disease. METHODS: In the AREST CF cohort study, children diagnosed with CF undergo annual bronchoscopies with bronchoalveolar lavage and ultra-low-dose, chest computed tomography (CT) up to 6-years-old. Spirometry was assessed 3-monthly from the age of 4years. Associations between de novo S. aureus acquisition before school age and CT and lung function at ages 5-7years were investigated...

The role of neutrophil elastase (NE) is poorly understood in bronchiectasis because of the lack of preclinical data and so most of the assumptions made about NE inhibitor potential benefit is based on data from CF. In this context, NE seems to be a predictor of long-term clinical outcomes and a possible target of treatment. In order to better evaluate the role of NE in bronchiectasis, a systematic search of scientific evidence was performed.Two investigators independently performed the search on PubMed and included studies published up to May 15, 2017 according to predefined criteria...

Massive hemoptysis caused by bronchiectasis threatens life, so early bronchial arterial embolization (BAE) is needed. In case 1, a 80-year-old female complained of hemoptysis and back pain caused by bronchiectasis and Stanford type B aortic dissection. In case 2, a 78-year-old male had history of the surgery of descending thoracic aortic aneurysm and bronchiectasis combined with aortopulmonary fistula. Both cases in bronchiectasis with massive hemoptysis were difficult to perform BAE due to complicated with acute aortic dissection and aortopulmonary fistula...
