The inter-relationship between chronic respiratory disease and reflux disease in the airway reflux paradigm is extremely complex and remains poorly characterised. Reflux disease is reported to cause or contribute to the severity of a number of respiratory tract diseases including laryngeal disorders, sinusitis, chronic cough, asthma, COPD, idiopathic pulmonary fibrosis, cystic fibrosis, bronchiectasis and bronchiolitis obliterans post lung transplant. It is now appreciated that reflux disease is not simply caused by liquid acid reflux but rather by a variety of chemical refluxates originating from the stomach and duodenum due to a number of different mechanisms.

COPD patients often also complain of bendopnoea but little is known about this symptom in this patient group. We objectively assessed 44 COPD patients attending pulmonary rehabilitation for bendopnoea in a tertiary referral centre to determine the potential mechanism and clinical implications of this symptom.
View Article and Find Full Text PDFRationale: Exacerbations are key events in the natural history of bronchiectasis, but clinical predictors and outcomes of patients with frequently exacerbating disease are not well described.
Objectives: To establish if there is a "frequent exacerbator phenotype" in bronchiectasis and the impact of exacerbations on long-term clinical outcomes.
Methods: We studied patients with bronchiectasis enrolled from 10 clinical centers in Europe and Israel, with up to 5 years of follow-up.
Background: Middle-lobe predominant bronchiectasis affecting the right middle-lobe and/or lingula (RMLP) is classically described in asthenic, elderly females with skeletal abnormalities or associated nontuberculous mycobacterial (NTM) infection.
Objectives: We aimed to evaluate the frequency and clinical characteristics of patients with an RMLP phenotype in a cohort of newly diagnosed bronchiectasis patients and determine associations with disease severity.
Methods: A retrospective observational cross-sectional cohort study of consecutive bronchiectasis patients in our institution was performed.
Background: This study assessed if bronchiectasis (BR) and rheumatoid arthritis (RA), when manifesting as an overlap syndrome (BROS), were associated with worse outcomes than other BR etiologies applying the Bronchiectasis Severity Index (BSI).
Methods: Data were collected from the BSI databases of 1,716 adult patients with BR across six centers: Edinburgh, United Kingdom (608 patients); Dundee, United Kingdom (n = 286); Leuven, Belgium (n = 253); Monza, Italy (n = 201); Galway, Ireland (n = 242); and Newcastle, United Kingdom (n = 126). Patients were categorized as having BROS (those with RA and BR without interstitial lung disease), idiopathic BR, bronchiectasis-COPD overlap syndrome (BCOS), and "other" BR etiologies.
Background: Patients with bronchiectasis often have concurrent comorbidities, but the nature, prevalence, and impact of these comorbidities on disease severity and outcome are poorly understood. We aimed to investigate comorbidities in patients with bronchiectasis and establish their prognostic value on disease severity and mortality rate.
Methods: An international multicentre cohort analysis of outpatients with bronchiectasis from four European centres followed up for 5 years was done for score derivation.
Introduction: Although bronchiectasis particularly affects people ≥65 years of age, data describing clinical characteristics of the disease in this population are lacking. This study aimed at evaluating bronchiectasis features in older adults and elderly, along with their clinical outcomes.
Methods: This was a secondary analysis of six European databases of prospectively enrolled adult outpatients with bronchiectasis.
Background And Objective: Hiatal hernias (HH) are associated with gastro-oesophageal reflux and may contribute to lung disease severity. We aimed to evaluate the prevalence of HH among stable non-cystic fibrosis bronchiectasis (NCFB) patients and determine associations with disease severity.
Methods: A retrospective cross-sectional cohort study of 100 consecutive NCFB patients in our institution was performed.

Background And Aim Of The Work: Sarcoidosis is a chronic granulomatous disorder of unknown etiology. In most patients the disease is self-limited, although for reasons unclear, others progress or die from progressive organ fibrosis. Growth factors have been implicated in the pathogenesis of other fibrotic lung conditions.

Introduction: A recent pilot study noted clinical benefit of macrolide therapy in the management of six lung transplant recipients with bronchiolitis obliterans syndrome (BOS), a condition previously regarded as irreversible.
Objective: To examine the effect of low-dose macrolides on lung function in lung allograft recipients with established BOS and to assess whether this benefit is sustained.
Methods: We retrospectively evaluated the effect of azithromycin (250 mg alternate days) on clinical status and lung function in 20 allograft recipients with established BOS, confirmed by decline in FEV(1) or FEF(25-75); consistent high-resolution computed tomography findings; and exclusion of acute rejection, infection, or anastomatic complications.
Although many lung allograft recipients achieve long-term survival, there is a lack of published data regarding these patients' functional status and quality of life (QoL). We evaluated all 10-year survivors at our institution and, utilizing the SF-36 questionnaire, compared their QoL to population normative and chronic illness data. Twenty-eight (29%) of 96 patients survived > or =10 years following 11 single, 6 bilateral and 11 heart-lung procedures.

Data evaluating TLI in bronchiolitis obliterans syndrome (BOS), the physiological manifestation of chronic lung allograft rejection, is very limited. We present our single center experience of the safety and efficacy of TLI in controlling progressive BOS in a retrospective study.

Background: HLA-DR2 (15) and 14 (6) have been recently proposed as susceptibility alleles for the development of sarcoidosis and HLA-DR15 as a marker of poor outcome, but validation in other populations is necessary.
Methods: Employing serological techniques, we HLA-typed 103 Irish sarcoidosis patients and 105 ethnically-matched healthy controls for class I A and B and II DR and DQ alleles.
Results: HLA-B5 (10% vs.

Objective: Susceptibility to sarcoidosis and coeliac disease has been linked to the class II haplotype HLA-DR3, DQ2, and an association between the two disorders has been suggested. As a pilot study, we have sought to determine the prevalence of coeliac disease in a cohort of Irish patients with sarcoidosis.
Design: Prospective, case-controlled study.

Background: Sarcoidosis is a systemic disorder of unknown cause, highly variable phenotype and unpredictable outcome. Antigen processing, inflammatory response and immunomodulation appear critical to development and prognosis of the disease.
Methods: We performed a comprehensive genomic analysis, applying high-density human GeneChip probe arrays (HUG95A, Affymetrix Inc.
