OBJECTIVE: The human papillomavirus causes recurrent respiratory papillomatosis. Although human papillomavirus prevalence is high, the incidence of papillomatosis is low. Thus, factors other than human papillomavirus infection probably contribute to recurrent respiratory papillomatosis. This study investigated whether patients with papillomatosis are more often infected with herpes simplex virus type 2 and chlamydia trachomatis and whether laryngopharyngeal reflux occurs in this group of patients more often...

Ineffective esophageal motility (IEM) is characterized by low to very low amplitude propulsive contractions in the distal esophagus, hence primarily affecting the smooth muscle part of the esophagus. IEM is often found in patients with dysphagia or heartburn and is commonly associated with gastroesophageal reflux disease. IEM is assumed to be associated with ineffective bolus transport; however, this can be verified using impedance measurements or evaluation of a barium coated marshmallow swallow. Furthermore, water swallows may not assess accurately the motor capabilities of the esophagus, since contraction amplitude is strongly determined by the size and consistency of the bolus...

BACKGROUND: Pepsin plays a role in gastroesophageal reflux (GER). Aims of this study were to verify if pepsin could be the cause of frequent bronchial exacerbations and to check if the persistence of chronic respiratory symptoms were correlated with pre-existing respiratory diseases. METHODS: From January to May 2016, 42 patients underwent a diagnostic bronchoscopy. All patients had a history of at least one bronchial exacerbation during the previous year. Bronchial lavage fluid specimens were obtained...

RATIONALE: COPD exacerbations are associated with disease progression, higher healthcare cost, and increased mortality. Published predictors of future exacerbations include previous exacerbation, airflow obstruction, poor overall health, home oxygen use, and gastroesophageal reflux. The value of adding blood biomarkers to clinical variables to predict exacerbations remains unproven. METHODS: Subjects from SPIROMICS (n=1544) and COPDGene (n=602) cohorts had 90 plasma or serum candidate proteins measured on study entry using Myriad-RBM multiplex panels...

BACKGROUND/AIMS: Respiratory symptoms are often associated with gastroesophageal reflux disease (GERD). Although the role of multichannel intraluminal impedance-pH (MII-pH) monitoring in GERD is clear, little is known regarding the characteristics of patients with respiratory symptoms based on MII-pH monitoring and anti-reflux therapy. We evaluated a cohort of GERD patients to identify the MII-pH parameters of GERD-related respiratory symptoms and to assess the anti-reflux therapy outcomes...

Among the interstitial lung diseases (ILD), idiopathic pulmonary fibrosis (IPF), chronic hypersensitivity pneumonitis and fibrotic connective tissue disease related ILD are associated with a worse prognosis with death occurring both from respiratory failure and serious associated co-morbidities. The recent development and approval of the antifibrotic agents nintedanib and pirfenidone, both of which reduced the rate of decline in lung function in patients with IPF in clinical trials, offer hope that it may be possible to alter the increased mortality associated with IPF...

Background. There is no gold standard test for diagnosis of gastroesophageal reflux disease (GERD) associated infantile wheezing. Objectives. To evaluate the value of bronchoalveolar lavage (BAL) pepsin assay in diagnosis of GERD in wheezy infants. Methods. Fifty-two wheezy infants were evaluated for GERD using esophageal combined impedance-pH (MII-pH) monitoring, esophagogastroduodenoscopy with esophageal biopsies, and BAL pepsin. Tracheobronchial aspirates from 10 healthy infants planned for surgery without history of respiratory problems were examined for pepsin...

A 42-year-old male presented with worsening gastroesophageal reflux disease symptoms and cough. The clinical symptoms during the early course of illness were striking for aspiration pneumonia. He was given a prescription of proton pump inhibitors and antibiotics. Rapid decline in the clinical condition with worsening respiratory status was noted. Worsening symptoms of fever, cough, and chest pain prompted further diagnostic work-up suggesting esophageal microperforation. Esophagogram was found to be suggestive of tracheoesophageal fistula...

Idiopathic pulmonary fibrosis (IPF) is a chronic progressive lung disease of unknown cause, occurring in adults, limited to the lungs and associated with the pathologic and radiologic pattern of usual interstitial pneumonia. Prognosis is poor, and most patients die of respiratory failure within 3 to 6 years from the onset of symptoms. Although our understanding of the pathogenesis of IPF has improved over the past two decades, the mechanisms responsible for this disorder have not been clearly defined. Aging is the single most important risk factor, but genetic, environmental, and diverse exogenous factors such as smoking, viral infections, chronic tissue injury (i...

More than one third of patients with chronic lung disease undergoing lung transplantation have pre-existing Abs against lung-restricted self-Ags, collagen type V (ColV), and k-α1 tubulin (KAT). These Abs can also develop de novo after lung transplantation and mediate allograft rejection. However, the mechanisms leading to lung-restricted autoimmunity remain unknown. Because these self-Ags are normally sequestered, tissue injury is required to expose them to the immune system. We previously showed that respiratory viruses can induce apoptosis in CD4(+)CD25(+)Foxp3(+) regulatory T cells (Tregs), the key mediators of self-tolerance...

OBJECTIVES/HYPOTHESIS: Antireflux therapy is incorporated in many treatment protocols for recurrent respiratory papillomatosis (RRP) because gastroesophageal reflux (GERD) is thought to worsen the disease course of RRP. It is unclear if GERD really aggravates the disease course. The aims of this systematic review were to 1) evaluate incidence of GERD among RRP patients and 2) report if GERD changes the clinical course or tissue properties of RRP. STUDY DESIGN: A search was conducted in PubMed, Embase, and Google Scholar, following the methods of Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guidelines...
