Abstract
Treatable traits is a personalized medicine approach to the management of airway disease. Assessing traits within the 3 domains of pulmonary, extrapulmonary, and behavioral/lifestyle/risk factor traits, and applying targeted treatments to effectively manage these traits, enables a holistic and personalized approach to care. Asthma is a heterogeneous and complex airway disease that is frequently complicated by several extrapulmonary traits that impact asthma outcomes and predict future outcomes. We propose that the identification of extrapulmonary and behavioral risk factor traits and the implementation of targeted therapy will lead to improved management of people with asthma. Furthermore, many extrapulmonary traits present as "connected comorbidities"; that is, they coexist with asthma, have an impact on asthma, and effective treatment improves both asthma and the comorbidity or the comorbidities may share a similar mechanism. In this review, we explore this concept and look at atopic dermatitis, chronic rhinosinusitis with nasal polyps, gastroesophageal reflux disease, anxiety, and depression as treatable traits of asthma and how these can be managed using this approach.

Abstract
BACKGROUND The interaction between the respiratory and gastrointestinal systems, and the role of the latter in the development of respiratory pathology, has been examined with a focus on gastro-oesophageal reflux disease (GORD). However, little data exists examining the link between oesophageal motility and respiratory disease. AIMS AND OBJECTIVES In this study, we examined patterns in oesophageal motility using high-resolution oesophageal manometry (HROM) in patients with refractory respiratory symptoms. METHODS Data were collected retrospectively for all patients that were investigated using HROM at a single centre for refractory respiratory symptoms between January 1st, 2011-December 1st, 2021. Patients were selected for investigation based on airway reflux symptoms, measured by the Hull Airways Reflux Questionnaire (HARQ). RESULTS 441 patients were investigated with HROM (64% female, mean age = 56.5 [SD = 13.9]). The commonest diagnoses of these patients were Chronic Cough (77%, n = 339), Asthma (10%, n = 44), and Interstitial Lung Disease (7%, n = 29). The prevalence of oesophageal dysmotility was 66% in our cohort. Those with oesophageal dysmotility had significantly higher HARQ scores than those with normal motility (40.6 vs 35.3, p < 0.001) and there was a significant inverse correlation between HARQ scores and distal contractile integral (DCI), a measure of oesophageal contractility. CONCLUSIONS Two-thirds of patients with refractory respiratory symptoms were found to have oesophageal dysmotility on HROM. These findings suggest motility disorders of the oesophagus may contribute to the development and progression of respiratory disease. This study highlights the need for further prospective study of the relationship between oesophageal dysmotility and respiratory disease.

Abstract
The aim of this review is to explore the relationship between esophageal syndromes and pulmonary diseases considering the most recent data available. Prior studies have shown a close relationship between lung diseases such as asthma, chronic obstructive pulmonary disorders (COPD), Idiopathic pulmonary fibrosis (IPF), and lung transplant rejection and esophageal dysfunction. Although the association has long been demonstrated, the exact relationship remains unclear. Clinical experience has shown a bidirectional relationship where esophageal disease may influence the outcomes of pulmonary disease and vice versa. The impact of esophageal dysfunction on pulmonary disorders may also be related to 2 different mechanisms: the reflux pathway leading to microaspiration and the reflex pathway triggering vagally mediated airway reactions. The aim of this review is to further explore these relationships and pathophysiologic mechanisms. Specifically, we discuss the proposed hypotheses for the relationship between the 2 diseases, as well as the pathophysiology and new developments in clinical management.

Abstract
BACKGROUND Asthma and gastro-oesophageal reflux disease (GORD) are common medical conditions that frequently co-exist. GORD has been postulated as a trigger for asthma; however, evidence remains conflicting. Proposed mechanisms by which GORD causes asthma include direct airway irritation from micro-aspiration and vagally mediated oesophagobronchial reflux. Furthermore, asthma might precipitate GORD. Thus a temporal association between the two does not establish that GORD triggers asthma. OBJECTIVES To evaluate the effectiveness of GORD treatment in adults and children with asthma, in terms of its benefits for asthma. SEARCH METHODS The Cochrane Airways Group Specialised Register, CENTRAL, MEDLINE, Embase, reference lists of articles, and online clinical trial databases were searched. The most recent search was conducted on 23 June 2020. SELECTION CRITERIA We included randomised controlled trials comparing treatment of GORD in adults and children with a diagnosis of both asthma and GORD versus no treatment or placebo. DATA COLLECTION AND ANALYSIS A combination of two independent review authors extracted study data and assessed trial quality. The primary outcome of interest for this review was acute asthma exacerbation as reported by trialists. MAIN RESULTS The systematic search yielded a total of 3354 citations; 23 studies (n = 2872 participants) were suitable for inclusion. Included studies reported data from participants in 25 different countries across Europe, North and South America, Asia, Australia, and the Middle East. Participants included in this review had moderate to severe asthma and a diagnosis of GORD and were predominantly adults presenting to a clinic for treatment. Only two studies assessed effects of intervention on children, and two assessed the impact of surgical intervention. The remainder were concerned with medical intervention using a variety of dosing protocols. There was an uncertain reduction in the number of participants experiencing one or more moderate/severe asthma exacerbations with medical treatment for GORD (odds ratio 0.53, 95% confidence interval (CI) 0.17 to 1.63; 1168 participants, 2 studies; low-certainty evidence). None of the included studies reported data related to the other primary outcomes for this review: hospital admissions, emergency department visits, and unscheduled doctor visits. Medical treatment for GORD probably improved forced expiratory volume in one second (FEV₁) by a small amount (mean difference (MD) 0.10 L, 95% CI 0.05 to 0.15; 1333 participants, 7 studies; moderate-certainty evidence) as well as use of rescue medications (MD -0.71 puffs per day, 95% CI -1.20 to -0.22; 239 participants, 2 studies; moderate-certainty evidence). However, the benefit of GORD treatment for morning peak expiratory flow rate was uncertain (MD 6.02 L/min, 95% CI 0.56 to 11.47; 1262 participants, 5 studies). It is important to note that these mean improvements did not reach clinical importance. The benefit of GORD treatment for outcomes synthesised narratively including benefits of treatment for asthma symptoms, quality of life, and treatment preference was likewise uncertain. Data related to adverse events with intervention were generally underreported by the included studies, and those that were available indicated similar rates regardless of allocation to treatment or placebo. AUTHORS' CONCLUSIONS Effects of GORD treatment on the primary outcomes of number of people experiencing one or more exacerbations and hospital utilisation remain uncertain. Medical treatment for GORD in people with asthma may provide small benefit for a number of secondary outcomes related to asthma management. This review determined with moderate certainty that with treatment, lung function measures improved slightly, and use of rescue medications for asthma control was reduced. Further, evidence is insufficient to assess results in children, or to compare surgery versus medical therapy.

Abstract
PURPOSE OF REVIEW Gastro-esophageal reflux is a possible cause of uncontrolled symptoms of asthma and should be actively investigated and treated before severe asthma is diagnosed and biological therapy started. RECENT FINDINGS Recent investigations on esophageal function and tissue biomarkers in patients with asthma and associated GERD have established a relevant role for esophageal motility and neuronal sensory abnormalities in linking the two diseases. Characterization of the underpinning inflammatory substrate has showed mixed results as both neutrophilic and eosinophilic type 2 inflammatory changes have been described. SUMMARY New findings regarding inflammatory mechanisms in GERD-associated asthma as well as new diagnostic tools to investigate functional esophageal abnormalities and characterize asthma endotype have identified potential treatable traits that may improve the clinical management and outcome of asthmatic patients with GERD.

Abstract
Gastroesophageal reflux and obstructive sleep apnea syndrome are conditions that practitioners have been encouraged to evaluate and treat as part of a comprehensive approach to achieving asthma control. In this review, the author looks at the evidence linking these two conditions as factors that may impact difficult-to-control asthma and looks critically at the evidence suggesting that evaluation and treatment of these conditions when present impacts asthma control.

Abstract
Gastroesophageal reflux disease encompasses a wide spectrum of disorders related to the reflux of gastric contents into the esophagus. Extraesophageal reflux (EER) may be suspected in patients with unexplained chronic cough, pharyngolaryngeal symptoms, and asthma. For physicians, suspected EER is challenging as there is currently no tool that can reliably make a definitive diagnosis. Endoscopic signs are not specific, pharyngeal and proximal reflux monitoring are not reliable, and if distal pH or pH-impedance monitoring can identify patients with abnormal reflux, they cannot predict the response to therapy. Controlled randomized trials have failed to reliably demonstrate any benefit of high-dose proton-pump inhibitors over placebo in patients with laryngeal symptoms, chronic cough, and asthma. Overall, the role of gastroesophageal reflux has been largely overestimated in patients with suspected EER. Especially when proton-pump inhibitors failed to improve symptoms, other diagnosis should be considered, such as functional laryngeal disorders which are probably much more prevalent in these patients than pathologic gastroesophageal reflux.

Abstract
This study aims to determine whether successful laparoscopic fundoplication for gastroesophageal reflux disease (GERD) can improve the control of hypertension. We conducted an observational study of GERD patients with hypertension. The esophageal and gastroesophageal symptoms of these patients were successfully treated with laparoscopic fundoplication, as measured by the reduced GERD symptoms and proton pump inhibitor consumption. A hypertension control scale was used to classify the use of antihypertensive medications and the quality of blood pressure control before and after anti-reflux surgery.Wilcoxon signed-ranks test was used for the statistical analyses. Seventy GERD patients were included in the analysis and followed up for a mean period of 3.5 ± 1.4 years. Prior to surgery, all participating patients were taking at least one class of antihypertensive medication, and 56 patients (80%) had intermittently high blood pressure. After surgery, the mean number of antihypertensive medication classes per patient was significantly reduced from 1.61 ± 0.77 pre-procedure to 1.27 ± 0.88 post-procedure (P < 0.001). The blood pressure of 48 of the 56 cases (86%) with preoperative intermittent high blood pressure returned to normal post procedure. A total of 50 patients (71%) recorded improvements on the hypertension control scale, with the overall mean score decreasing from 3.1 ± 1.0 preprocedure to 1.4 ± 1.0 post-procedure (P < 0.001). Therefore, successful laparoscopic fundoplication may result in better blood pressure control in some hypertensive GERD patients. This result suggests a possible connection between gastroesophageal reflux and hypertension.

Abstract
Objectives: The H+/K+-ATPase proton pump has been demonstrated in human laryngeal submucosal glands, and is not solely present in the parietal cells of the stomach. Although proton secretion is present in the lung, a variety of mechanisms have been elucidated. The hypothesis of this study is that the H+/K+-ATPase proton pump is one additional pathway of proton secretion in the human lung. Methods: Fourteen surgical lung specimens from 10 subjects were retrospectively obtained after approval from our Human Subjects Committee. Banked human stomach tissue was used for comparative positive and negative controls. Sections were immunostained with 2 monoclonal antibodies selectively reactive with alpha or beta subunits of the H+/K+-ATPase proton pump. Results: In the human lung, consistent staining for both subunits was present in the mucous gland cells and ducts in all specimens in which mucous glands were present (6 specimens from 5 subjects). Overall, weak to strong staining was present in focal areas within the multicellular mucous glands. There was only scant focal staining in the respiratory epithelium in 4 specimens. Stomach parietal cells exhibited strongly positive staining for both subunits of the proton pump. There was no staining in stomach cells that were not morphologically consistent with parietal cells. Conclusions: The H+/K+-ATPase proton pump is present in mucous cells and ducts in the human lung, with some variable expression noted. Proton pump inhibitor pharmacotherapy may have a site of action in the human lung, explaining some of the controversies otherwise attributable to interrelatedness of aerodigestive tract disease.

Abstract
This study aimed to investigate the outcome of treatment with Stretta radiofrequency (SRF) or laparoscopic Nissen fundoplication (LNF). A total of 137 gastroesophageal reflux disease (GERD) patients with severe asthmatic symptoms who responded inadequately to medical treatment for asthma were investigated. The patients were followed up 1 year and 5 years after SRF (n = 82) or LNF (n = 55) treatment. A questionnaire covering 29 related symptoms and medication use was employed. Digestive, respiratory, and ear-nose-throat (ENT) symptom scores significantly decreased after antireflux treatment. Symptom scores respectively changed from 17.2 ± 10.1, 31.9 ± 6.6, and 21.1 ± 11.8 to 5.0 ± 6.2, 11.5 ± 10.2, and 6.3 ± 6.8 at 1 year and to 5.6 ± 6.5, 13.1 ± 10.1, and 7.8 ± 7.2 at 5 years (P < 0.001). The outcome of LNF was significantly better than that of SRF in terms of digestive (P < 0.001, P = 0.001), respiratory (P = 0.006, P = 0.001), and ENT symptoms (P = 0.006, P = 0.003) at both 1 year and 5 years. SRF and LNF were both effective against the digestive symptoms of GERD as well as GERD-related severe asthmatic and ENT symptoms, with better outcomes exhibited by the LNF group. Severe asthmatic symptoms and GERD were closely associated, and this finding warrants further study.

Abstract
BACKGROUND Asthma, persistent rhinosinusitis, and/or nasal polyposis accompanying non-steroidal anti-inflammatory drug (NSAID) intolerance is defined as aspirin-exacerbated respiratory disease (AERD). Although the literature includes considerable data on comorbidities in asthma, data on comorbidities in AERD have not been previously published. OBJECTIVE This study aimed to determine the prevalence of comorbidities in AERD and compare the findings to those in asthmatic patients. MATERIALS AND METHODS The records for 330 AERD patients that presented to our allergy clinic were reviewed. Patients with urticaria/angio-oedema type reactions to NSAIDs were included in the pseudo Samter's group (n=83) and 338 randomly selected NSAID-tolerant asthma patients constituted the control group. RESULTS Gender, age at presentation, age at onset of asthma, and follow-up periods were similar in all groups. Hypertension (P=0.035), diabetes mellitus (P=0.323), gastro-oesophageal reflux (P<0.001), psychological disorders (P=0.099), obesity (P=0.003), and hyperlipidaemia (P=0.002) were significantly more prevalent in the asthma group. Interestingly, coronary artery disease (CAD) and congestive heart failure (CHF) were more common in the AERD group (P=0.178); CAD/CHF was associated with AERD (OR: 4.5; 95% CI: 1.206-16.93). CONCLUSION AERD and asthma are associated with several comorbidities. Even though systemic steroid dependency and severe asthma were significantly more common in the AERD group, comorbidities occurred more frequently in the asthma group. Additional longitudinal studies are needed to more clearly discern if the risk of CAD/CHF is increased in AERD.

Abstract
Background Asthma, laryngitis and chronic cough are atypical symptoms of the gastroesophageal
reflux disease. Aim To analyze the efficacy of laparoscopic surgery in the remission of
extra-esophageal symptoms in patients with gastroesophageal reflux, related to
asthma. Methods Were reviewed the medical records of 400 patients with gastroesophageal reflux
disease submitted to laparoscopic Nissen fundoplication from 1994 to 2006, and
identified 30 patients with extra-esophageal symptoms related to asthma. The
variables considered were: gender, age, gastroesophageal symptoms (heartburn, acid
reflux and dysphagia), time of reflux disease, treatment with proton pump
inhibitor, use of specific medications, treatment and evolution, number of attacks
and degree of esophagitis. Data were subjected to statistical analysis, comparing
the pre- and post-surgical findings. Results The comparative analysis before surgery (T1) and six months after surgery (T2)
showed a significant reduction on heartburn and reflux symptoms. Apart from that,
there was a significant difference between the patients with daily crises of
asthma (T1 versus T2, 45.83% to 16.67%, p=0.0002) and continuous crises (T1,
41.67% versus T2, 8.33%, p=0.0002). Conclusion Laparoscopic Nissen fundoplication was effective in improving symptoms that are
typical of reflux disease and clinical manifestations of asthma.

Abstract
A wide variety of symptoms and diseases of the upper aerodigestive tract are associated to gastro-oesophageal reflux disease (GORD). These disorders comprise a large variety of conditions such as asthma, chronic otitis media and sinusitis, chronic cough, and laryngeal disorders including paroxysmal laryngospasm. Laryngo-pharyngeal reflux disease is an extraoesophageal variant of GORD that can affect the larynx and pharynx. Despite numerous research efforts, the diagnosis of laryngopharyngeal reflux often remains elusive, unproven and controversial, and its treatment is then still empiric. Aim of this paper is to review the current literature on upper aerodigestive tract disorders in relation to pathologic gastro-oesophageal reflux, focusing in particular on the pathophysiology base and results of the surgical treatment of GORD.

Long-term effects of fundoplication in children with chronic airway diseases. J Pediatr Surg 2015; 50:206-10. [PMID: 25598124 DOI: 10.1016/j.jpedsurg.2014.09.079] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/21/2014] [Revised: 09/05/2014] [Accepted: 09/09/2014] [Indexed: 12/12/2022]
Abstract
BACKGROUND Association between chronic airway diseases (CAD) and gastroesophageal reflux disease (GERD) is well described, but causality has not yet been conclusively established. This study evaluates the therapeutic significance of laparoscopic Thal fundoplication in children with CAD and diagnosed GERD. METHODS We performed a retrospective analysis of 182 neurologically nonimpaired children, all with medically refractory CAD and GERD undergoing laparoscopic Thal fundoplication. The clinical response, ability to wean oral and inhaled medication and satisfaction with postoperative results were evaluated. RESULTS Main symptoms disappeared completely in 68.7% of patients and were markedly improved in a further 22% of patients following surgery. Complete discontinuation of medication was achieved in 70.1-96.4% of cases and reduced in a further 1.8-23.5%. One intraoperative complication occurred (gastric perforation), however no conversion to laparotomy was necessary. Postoperative Dumping Syndrome occurred in 1% of cases and was managed dietetically. Prolonged postoperative dysphagia occurred in 4.3% of patients, but disappeared within 8 weeks in all but one case. CONCLUSIONS Our study suggests that Thal fundoplication in neurologically nonimpaired children with CAD and documented GERD is effective and safe. Children unresponsive to preoperative medical management showed significant improvement in airway symptoms together with a marked reduction in the need for medication. We conclude that laparoscopic Thal fundoplication represents a significant treatment worthy of consideration in this group of patients.

Abstract
At the very time of global paying the highest attention to the worst insults of smoking as well as haze on the airway, everybody knows both are exogenous and noticeable. However, people mostly, including many medical personnel, do not know how badly the gastroesophageal reflux (GER) insults on our own airway. Symptoms of GER are commonly seen as heartburn and regurgitation, which can be mostly tolerated. However, when the up going gastric content reversely passes the esophagus and then the distal pharynx, where it appears a beak like stricture, serving as a nozzle, so as to produce numerous micro-particles and reach the oro-nasal cavity and also the airway causing allergic rhinitis and asthmatic attacks, even pulmonary parenchyma lesions. It will reduce life quality or even jeopardize life. The point that the endogenous insult appears in the respiratory system, but originates from the digestive tract is not well known and often undiagnosed and not correctly treated. The GER induced airway challenge is a treatable and preventive entity, as soon as a diagnosis is made, a good relief could be expected by means of life style adjustment, medicine, or fixation of the patulous cardia through radiofrequency or fundoplication. The author Dr. Zhonggao Wang had suffered it for long and symptoms disappeared for 8 years after anti-reflux surgery. Here is a presentation of Dr. Zhonggao Wang and his team's work and would call attention to the public so as to recognize this relatively unknown entity - a treatable condition occurring from human itself, but not from outside surroundings as smoking or haze does.

Abstract
BACKGROUND To evaluate the differences in the existence and size of dead space in patients with and without Gastroesophageal Reflux Disease (GERD and non-GERD) expressed through the size of intrapulmonary shunt (QS/QT). MATERIAL/METHODS The study enrolled 86 subjects - 43 patients referred for endoscopy because of symptoms of GERD (heartburn, acid regurgitation, dysfagia) and 43 healthy subjects with similar anthropometric characteristics without GERD symptoms. Based on endoscopy findings, patients were classified into the erosive reflux disease (ERD) group and non-erosive reflux disease (NERD) group. Spirometry values, single-breath diffusing capacity of the lung for carbon monoxide (DLCO) and intrapulmonary shunt (venous shunt - QS/QT) determined by the oxygen method were measured in all participants. RESULTS Statistically significant differences between GERD and non-GERD groups in FVC (p=0.034), FEV1 (p=0.002), FEV1/FVC (p=0.001), and PEF (p=0.001) were observed. There were no statistically significant differences in FEF 25% (p=0.859), FEF 50% (p=0.850), and FEF 75% (p=0.058). Values of DLCO (p=0.006) and DLCO/VA (p=0.001) were significantly lower and QS/QT was significantly higher (p=0.001) in the GERD group than in the non-GERD group. However, in both groups the average values of DLCO and DLCO/VA expressed as a percentage of predictive values were within normal range, while the value of QS/QT in the GERD group showed pathological (6.0%) mean value (normal value ≤ 5.0%). There were no significant differences in respiratory function test results between patients with ERD and NERD. CONCLUSIONS Our results suggest that microaspiration of stomach contents may cause surfactant damage, development of microatelectasis, and dead space expansion with consequent increase of intrapulmonary (venous) shunt.

Abstract
BACKGROUND The prevalence of gastroesophageal reflux (GER) in children with asthma is higher than in healthy controls, but the nature and direction of this association is unclear. OBJECTIVE The aim of our study was to assess the relationship between esophageal acid exposure and the clinical features of asthma in children. METHODS In total, 66 children (mean age 122.8 months [SD 44.89 months]) with chronic pulmonary symptoms, fulfilling diagnostic criteria of persistent asthma, underwent 24-hour esophageal pH monitoring and answered a detailed questionnaire-based survey. The questionnaire topics included environmental factors, familial history, current and previous clinical symptoms, atopy, asthma severity, and medication. RESULTS Abnormal results of 24-hour esophageal pH monitoring were found in 28 out of 66 children (42.4%). Age, sex, severity of asthma, environmental factors, spirometry results, and the type of medication did not correlate with esophageal acid exposure. However, children with abnormal pH results developed asthma significantly earlier (asthma onset 3.63 years [SD 2.52 years] vs 5.77 years [SD 3.82 years]; p < .01). Nonatopic individuals had more intensive esophageal acid exposure than atopic ones (Boix-Ochoa score 28.19 [SD 18.26] vs 18.26 [SD 12.84]; p < .048). The intensity of GER was also significantly correlated with frequent or difficult-to-control nighttime asthma attacks. CONCLUSIONS There are differences in clinical features of asthma in children with regard to the intensity of esophageal acid exposure. Symptoms of asthma in nonatopic individuals with early onset and difficult-to-control nighttime asthma attacks suggest the possibility of concomitant, clinically relevant GER.

Abstract
BACKGROUND Increased prevalence of respiratory symptoms has been commonly reported in patients with gastro-oesophageal reflux disease (GERD). AIM To introduce a novel Lung-Sound-Monitoring device that allows simultaneous measurement of both nocturnal respiratory symptoms and episodes of acidic and biliary refluxes. METHODS Nocturnal respiratory symptoms (coughing and wheezing) were continuously recorded in 20 healthy subjects and 30 reflux patients with respiratory symptoms in parallel to combined pH-monitoring and Bilitec measurement. RESULTS Analysis could be completed in 20 healthy subjects and in 25 patients with reflux. A clear temporal correlation to reflux phases was detected in 49% of coughing and 41% of wheezing events, respectively. Moreover, 89% of the coughing and 100% of the wheezing events succeeded reflux episodes. Finally, the technique was capable of assessing a statistically significant difference between patients and controls regarding the occurrence of these symptoms. CONCLUSIONS Our pilot study establishes the Lung-Sound-Monitoring system as a unique tool to measure objectively the temporal correlation between gastroesophageal reflux and the appearance of respiratory symptoms. It represents a useful technique to identify patients with respiratory symptoms due to reflux, and therefore allows one to determine and quantify the impact of therapeutic interventions such as antireflux therapy on respiratory symptoms.

Abstract
Asthma is a common and serious illness with suboptimal outcomes of care. Epidemiological studies show certain comorbidities occurring more frequently than expected with asthma, with some being associated with poor control and a differential response to therapy options. This review summarizes the evidence of clinically important comorbidities, focusing on the best-explored conditions, including rhinitis and rhinosinusitis, anxiety and depression, obesity, gastroesophageal reflux, smoking and dysfunctional breathing. The evidence of epidemiological and pathophysiological associations for these comorbidities is explored, and the practical therapeutic implications are considered. Comorbidities are important for clinicians treating asthma as they may be markers of patients at risk of poor outcomes, they may point to specific effective treatment options and they are important to researchers as possible confounding factors in clinical trials.

Abstract
BACKGROUND/AIM The relation between respiratory disorders and reflux symptoms has been debated since the beginning of the last century and the interest in this question has increased during the last few decades. This study aims to investigate the relation between specified respiratory disorders and reflux symptoms and examine the correlations between respiratory disorders and endoscopic findings in patients with gastroesophageal reflux disease. PATIENTS AND METHODS This study included 515 patients evaluated for gastroesophageal reflux disease (GERD) by patient self-report symptom questionnaire; modified four grade Likert scale and endoscopic assessment using endoscopic Los Angeles Classification. All participants were asked about various respiratory symptoms experienced during the past six months and exposed to measuring body mass index (BMI), medical history, pulmonary physical examination, chest X-ray, respiratory function tests and available sleep studies. RESULTS A total number of 515 patients were categorized according to endoscopic findings into two groups; (group1) subjects with normal endoscopic studies (NERD) 118 (22.9%) patients and (group2) subjects with abnormal endoscopic studies (ERD) 397 (77.1%). The proportion of females was significantly higher in ERD group (80.1%) as compared with NERD group (62.7%) ( P < 0.02). Duration of reflux symptoms found to be significantly prolonged in ERD group ( P < 0.03). The cases of ERD group were more likely to be overweight (BMI>25) P < 0.02. History of pulmonary symptoms preceding GERD symptoms was found in 15% of patients. There were 294 patients (57.1%) with different pulmonary manifestations. These manifestations were significantly higher among female group ( P < 0.01) and among obese, above 40 years old ( P < 0.001, 0.05 respectively). Among all patients with respiratory manifestations the commonest disorders diagnosed were chronic pharyngitis (50.3%), chronic bronchitis (15.8%), bronchial asthma (12.6%) and recurrent pneumonia (3.3%). Obstructive sleep apnea and recurrent hemoptysis were present in 2.7% and 1.5% of the studied patients respectively. There were three cases of chronic lung abscess. There was a significant difference between ERD and NERD groups in their relations to respiratory disorders ( P < 0.001). There were statistically significant differences in FEV1, FVC and FEV1/FVC ( P < 0.02, P < 0.05 and P < 0.05) respectively in ERD group as compared with NERD group. CONCLUSION The study confirms the strong link between gastroesophageal reflux symptoms and various respiratory disorders. Endoscopy of the upper digestive tract remains an important exam in the evaluation of GERD. Respiratory symptoms are more prevalent among erosive esophagitis patients with a positive correlation with degree of severity. There is direct relationship between the severity of airways obstruction as detected by FEV1 and FEV1/FVC and GER symptoms.

Abstract
Gastroesophageal reflux disease (GERD) may cause, trigger or exacerbate many pulmonary diseases. The physiological link between GERD and pulmonary disease has been extensively studied in chronic cough and asthma. A primary care physician often encounters patients with extra esophageal manifestations of GERD in the absence of heartburn. Patients may present with symptoms involving the pulmonary system; noncardiac chest pain; and ear, nose and throat disorders. Local irritation in the esophagus can cause symptoms that vary from indigestion, like chest discomfort and abdominal pain, to coughing and wheezing. If the gastric acid reaches the back of the throat, it may cause a bitter taste in the mouth and/or aspiration of the gastric acid into the lungs. The acid can cause throat irritation, postnasal drip and hoarseness, as well as recurrent cough, chest congestion and lung inflammation leading to asthma and/or bronchitis/ pneumonia. This clinical review examines the potential pathophysiological mechanisms of pulmonary manifestations of GERD. It also reviews relevant clinical information concerning GERD-related chronic cough and asthma. Finally, a potential management strategy for GERD in pulmonary patients is discussed.

Abstract
OBJECTIVE To review the concept of a possible link between asthma and obstructive sleep apnea syndrome (OSAS) and the impact on asthma symptoms of treatment of OSAS with continuous positive airway pressure (CPAP) in patients with both conditions. DATA SOURCES The Ovid, MEDLINE, and PubMed databases from 1950 to the present were searched for relevant articles regarding a possible relationship between asthma and OSAS and the effectiveness of CPAP in treating OSAS. STUDY SELECTION Articles describing pathophysiologic conditions occurring in OSAS that may be linked to asthma pathogenesis were used for this review. RESULTS The data suggest that OSAS is an independent risk factor for asthma exacerbations. CPAP has been shown in prospective clinical studies to have a positive impact on asthma outcome in patients with concomitant OSAS. Ameliorative mechanisms of treatment with CPAP include mechanical and neuromechanical effects, gastroesophageal acid reflux suppression, local and systemic anti-inflammatory effects (including suppression of increased serum levels of inflammatory cytokines, chemokines, and vascular endothelial growth factor), cardiac function improvements, leptin level suppression, weight reduction, and sleep restoration. CONCLUSIONS Asthma and OSAS are increasingly troublesome public health issues. Mounting evidence implicates OSAS as a risk factor for asthma exacerbations, thereby linking these 2 major epidemics. We describe potential mechanisms whereby CPAP, the first line of therapy for OSAS, might modify airway smooth muscle function and asthma control in patients with both disorders. Despite the ever-increasing population of patients with both disorders, large, prospective, randomized controlled studies are necessary to more fully evaluate CPAP and asthma outcomes.

Abstract
BACKGROUND The development of well-tolerated acid suppressant drugs has stimulated substantial growth in the number of trials assessing therapy options for gastro-oesophageal reflux disease (GERD). AIM To develop consensus statements to inform clinical trial design in adult patients with GERD. METHODS Draft statements were developed employing a systematic literature review. A modified Delphi process including three rounds of voting was used to reach consensus. Between voting, statements were revised based on feedback from the Working Group and additional literature reviews. The final vote was at a face-to-face meeting that included discussion time. Voting was conducted using a six-point scale. RESULTS At the last vote, 93% of the final 102 statements achieved consensus (defined a priori as being supported by >or=75% of the votes). The Working Group strongly supported the development of validated patient-reported outcome instruments. Symptom assessments carried out by the investigator were considered unacceptable. There was agreement that exclusion from clinical trials should be minimized to improve generalizability, that prospective evaluation ideally requires electronic timed/dated methods and that endoscopists should be blinded to patient symptom status. CONCLUSIONS Implementation of the consensus statements will improve the quality and comparability of trials, and make them compatible with regulatory requirements.

Abstract
BACKGROUND Respiratory manifestations represent one of the most prevalent and difficult-to-manage extra-oesophageal syndromes of gastro-oesophageal reflux disease. AIMS To review the epidemiology, pathophysiological mechanisms and therapeutic outcomes of reflux-related respiratory disorders. METHODS Search of the literature published in English using PubMed database. RESULTS There is a discrepancy between the high prevalence of reflux in asthmatics and the limited efficacy of antireflux therapies. Asthma per se may cause reflux. Patients with difficult-to-treat asthma and/or nocturnal symptoms should be screened for reflux. Reflux can induce chronic cough through different mechanisms including micro-aspiration and both local and central reflexes. Cough and reflux may precipitate each other. A meta-analysis found no significant difference between placebo and proton pump inhibitors in the resolution of cough. Encouraging results have been reported, following antireflux surgery in patients selected on the basis of pH-impedance monitoring. Attention has been drawn to obstructive sleep apnoea syndrome. CONCLUSIONS The role of gastro-oesophageal reflux disease in the pathogenesis of miscellaneous respiratory disorders has been discussed for decades and established in asthma and cough. However, no major therapeutic advances have been reported recently. Future trials should concentrate on patient selection and the control of efficacy using recently developed technologies, such as pH-impedance monitoring.

Abstract
Gastroesophageal reflux disease (GERD) is currently one of the most common health problems in the Western world, affecting up to 20% of the adult population weekly and 50% monthly. It generates substantial suffering among patients as well as significant costs to both patients and society in general. GERD can further result in serious complications such as esophageal strictures, Barrett's esophagus and esophageal adenocarcinoma. This review discusses the current knowledge on risk factors and potential protective factors in the development of GERD.

Abstract
BACKGROUND Gastroesophageal reflux disease, considered one of the most common digestive diseases in western countries, has been very much studied. The great number of publications in medical literature based upon this issue must be pointed out. However, some of its aspects remain controversial. AIMS To emphasize important topics of the disease and to present a review on the theme. The following topics were reviewed: defi nition, prevalence, clinical complaints, indications and limitations of the major diagnostic methods and medical, surgical and endoscopic treatments. MATERIAL AND METHODS We searched, by internet: selected review articles, consensus, guidelines and systematic reviews with meta-analysis, published in the last 5 years (from 2000 to 2005), in the following data bases: Cochrane Central Register of Controlled Trials (The Cochrane Library) and PubMed. Among lots of papers which were found, we selected nine systematic reviews with meta-analysis, fi ve review articles, fi ve guidelines and four consensus, that dealt with the topics we had decided to review. It must be pointed out that, as it has been observed in our bibliographical references, not only the publications found were taken into account; other relevant ones (some of them published previously to the analyzed time period) were considered in the composition of this present paper. CONCLUSIONS Among the 12 conclusions presented, two have to be emphasized: 1. the esophageal multichannel intraluminal impedance has largely contributed to the better knowledge of the gastroesophageal reflux disease and it suggests, when associated with pHmetry (esophageal impedance-pHmetry), as a new gold standard to the gastroesophageal reflux diagnosis and 2: among the gastroesophageal reflux disease symptoms some of them may be considered acid dependents and can usually get good responses to the proton pump inhibitors. Nevertheless, there are also some symptoms which are more dependent on the physical presence of the reflux rather than its acidity. Such symptoms, which do not depend so much on the acidity of the reflux, are not well controlled by the proton pump inhibitors.

Abstract
Gastroesophageal reflux disease often presents as heartburn and acid reflux, the so-called "typical" symptoms. However, a subgroup of patients presents a collection of signs and symptoms that are not directly related to esophageal damage. These are known collectively as the extraesophageal manifestations of gastroesophageal reflux disease. Principal among such manifestations are bronchospasm, chronic cough and laryngitis, which are classified as atypical symptoms. These manifestations comprise a heterogeneous group. However, some generalizations can be made regarding all of the subgroups. First, although the correlation between gastroesophageal reflux disease and the extraesophageal manifestations has been well established, a cause-and-effect relationship has yet to be definitively elucidated. In addition, the main proposed pathogenic mechanisms of extraesophageal reflux are direct injury of the extraesophageal tissue (caused by contact with gastric acid) and the esophagobronchial reflex, which is mediated by the vagus nerve. Furthermore, gastroesophageal reflux disease might not be considered in the differential diagnosis of patients presenting only the atypical symptoms. In this article, we review the extraesophageal manifestations of gastroesophageal reflux disease, discussing its epidemiology, pathogenesis, diagnosis and treatment. We focus on the most extensively studied and well-established presentations.

Abstract
OBJECTIVES Acid gastro-esophageal reflux has been shown associated with chronic pulmonary diseases. The role of non-acid refluxes in these children is still unknown. Therefore we investigated the prevalence of acid and non-acid refluxes, and their association with desaturations, in children with chronic pulmonary symptoms. METHODS In 25 children aged 6 months to 15 years with unexplained chronic cough, wheeze or sputum production, refluxes were assessed by 24h-multiple intra-esophageal impedance measurements, simultaneous pH metry and continuous recording of oxygen saturation. RESULTS pH in the proximal and distal esophagus as well as six impedance channels were evaluated in all subjects. A mean of 129.4 refluxes per day per patient was detected. Complete and technically usable readings of oxygen saturation were obtained in 14 children. In this group the subjects had a mean of 112.6 refluxes and 92.6 desaturations per day per patient. The symptom index and symptom sensitivity index for acid refluxes were 34.7% and 24.6%, respectively, for non-acid refluxes 3.0% and 66.7%, respectively. CONCLUSIONS We found a high prevalence of acid reflux and a very low number of non-acid refluxes in this population. The symptom index was negative for all types of reflux, whereas the symptom sensitivity index was positive for both acid and non-acid reflux. Our data support a relation between acid gastro-esophageal refluxes and chronic pulmonary symptoms; however, this study does not support a role of non-acid reflux in children with respiratory symptoms, which are not on antacid medication.

Abstract
Asthma is a disorder of the lungs characterized by increased responsiveness of the airways, as manifested by episodes of wheezing and increased resistance to expiratory airflow because of varying degrees of smooth muscle contraction, edema of the mucosa, and mucus in the lumen of the bronchi and bronchioles. The stimuli vary widely and include antigens, infection, air pollutants, respiratory tract irrtants, exercise, and emotional factors. This condition is completely different from distress breathing because of laryngotracheal spasm. One of its causes is the gastric content reflux through the pharynx to the larynx because of gastroesophageal reflux disease (GERD), in addition to the typical human avian flu that may cause immediate suffocation by laryngospasm owing to acute larygotrachitis. A patient suffered from GERD without esophageal symptoms, which was diagnosed and treated as bronchial asthma during his five emergency admissions. The admissions were because of episodic attacks of severe air hunger owing to an extreme throat tightening. The patient was being treated for as long as two years. After the correct diagnosis was made and treatment of laporascopic fundaplication was performed, the longstanding "bronchial asthma", after all, completely disappeared. The concept of "not asthma, but GERD" seems undervalued, unappreciated, even misunderstood among patients with intractable asthma. Therefore, such a case is reported in detail, similar cases are mentioned briefly as well, and a mechanism responsible for GERD-originated larryngo-or laryngotracho-spasm is proposed.

Abstract
Obstructive sleep apnea (OSA) and asthma are potentially linked at several levels. The pathophysiology of these two conditions seems to overlap significantly, as airway obstruction, inflammation, obesity, and several other factors are implicated in the development of both diseases. Gastroesophageal reflux disease (GERD), cardiovascular complications, obesity itself, and the underlying inflammatory processes are all complex contributory factors that provide hypothetical links. Furthermore, a collateral rise in prevalence of both OSA and asthma has been noticed during the past few years, occurring in association with the emerging epidemic of obesity, a common risk factor for both conditions. OSA and asthma share many other risk factors as well. We propose a hypothetical OSA-asthma relationship that has implications on the diagnosis and management of patients presenting with either condition singly. Clinicians should be aware that OSA might complicate asthma management. Based on this hypothesis, we suggest that the treatment of the individual patient who experiences both asthma and OSA needs to be multidisciplinary and comprehensive. This hypothetical association of asthma and OSA, though described anecdotally, has not been systematically studied. In particular, the influence of continuous positive airway pressure therapy (for sleep apnea) on asthma outcomes (such as quality of life, steroid utilization, emergency room visits) and fatality needs to be studied further.

Abstract
OBJECTIVES A globally acceptable definition and classification of gastroesophageal reflux disease (GERD) is desirable for research and clinical practice. The aim of this initiative was to develop a consensus definition and classification that would be useful for patients, physicians, and regulatory agencies. METHODS A modified Delphi process was employed to reach consensus using repeated iterative voting. A series of statements was developed by a working group of five experts after a systematic review of the literature in three databases (Embase, Cochrane trials register, Medline). Over a period of 2 yr, the statements were developed, modified, and approved through four rounds of voting. The voting group consisted of 44 experts from 18 countries. The final vote was conducted on a 6-point scale and consensus was defined a priori as agreement by two-thirds of the participants. RESULTS The level of agreement strengthened throughout the process with two-thirds of the participants agreeing with 86%, 88%, 94%, and 100% of statements at each vote, respectively. At the final vote, 94% of the final 51 statements were approved by 90% of the Consensus Group, and 90% of statements were accepted with strong agreement or minor reservation. GERD was defined as a condition that develops when the reflux of stomach contents causes troublesome symptoms and/or complications. The disease was subclassified into esophageal and extraesophageal syndromes. Novel aspects of the new definition include a patient-centered approach that is independent of endoscopic findings, subclassification of the disease into discrete syndromes, and the recognition of laryngitis, cough, asthma, and dental erosions as possible GERD syndromes. It also proposes a new definition for suspected and proven Barrett's esophagus. CONCLUSIONS Evidence-based global consensus definitions are possible despite differences in terminology and language, prevalence, and manifestations of the disease in different countries. A global consensus definition for GERD may simplify disease management, allow collaborative research, and make studies more generalizable, assisting patients, physicians, and regulatory agencies.

Abstract
BACKGROUND In spite of numerous investigations, the relation between respiratory symptoms and reflux symptoms in the general population remains unclear, since population-based studies are few. STUDY OBJECTIVES To investigate the relation between respiratory symptoms and reflux symptoms in the population. SUBJECT AND METHODS In a cohort of 65,363 individuals representing 71.2% of the adult population in the Norwegian county of Nord-Trøndelag, 58,596 individuals (89.6%) responded to questions concerning reflux symptoms. The 3,153 persons (5.4%) with severe and recurrent reflux symptoms constituted the case group, and the 40,210 persons (68.6%) without reflux symptoms served as the control group. Odds ratios (ORs) with 95% confidence intervals (CIs) represented relative risks. Potential confounding was tested in multivariable logistic regression analysis. RESULTS Persons with asthma had reflux to a 60% greater extent than those without asthma after including adjustment for asthma medication (OR, 1.6; 95% CI, 1.4 to 1.9). There was a statistically significant dose-response association between breathlessness and reflux symptoms (p for trend < 0.0001), and the OR of severe breathlessness was 12.0 (95% CI, 9.5 to 15.2). Persons with heavy and wheezy breathing, daily cough, daily productive cough, or chronic cough showed a twofold to threefold statistically significant increase in risk of reflux symptoms. Adjustment for asthma or use of asthma medication did not substantially influence the risk estimates for any of the studied respiratory disorders. CONCLUSIONS Reflux symptoms commonly coexist with asthma and other respiratory symptoms on a population-based level, seemingly irrespective of asthma medication.

Abstract
Nissen fundoplication is applied for patients with gastroesophageal reflux disease (GERD), usually because of symptoms of esophageal injury. When presenting symptoms are extraesophageal, there is less enthusiasm for operative control of reflux because of concerns of etiology and efficacy. This study was undertaken to evaluate the efficacy of laparoscopic Nissen fundoplication in palliating extraesophageal symptoms of GERD. Patients were asked to score their symptoms before and after laparoscopic Nissen fundoplication on a Likert scale (0 = never/none to 5 = always/every time I eat). A total of 322 patients with extraesophageal symptoms (asthma, cough, gas/bloat, chest pain, and odynophagia) of 4 to 5 were identified and analyzed. After fundoplication, all extraesophageal symptom scores improved (P < 0.0001 for all, Wilcoxon matched-pairs test). Likewise, postoperative symptoms were noted to be greatly improved or resolved in 67 per cent to 82 per cent of patients for each symptom. Furthermore, after fundoplication, patients were less likely to modify their dietary (82% vs 49%) or sleeping habits (70% vs 28%) to avoid initiating/exacerbating symptoms. Although extraesophageal symptoms are conventionally thought to be inadequately palliated by surgery, this study documents excellent relief of extraesophageal symptoms after laparoscopic Nissen fundoplication, denotes high patient satisfaction, and encourages application of laparoscopic Nissen fundoplication.

Abstract
An association between asthma and gastroesophageal reflux disease (GERD) has long been recognized both mechanistically and epidemiologically. The clinical relevance of this interplay continues to be explored, with special interest given to the role of GERD in the worsening of asthma. The effect of GERD is most frequently contemplated in patients with asthma that is difficult to control. Medical and surgical anti-reflux trials attempting to alter asthma symptoms have reported mixed but generally underwhelming results, although asthma symptom scores are generally improved following effective treatment of GERD. Many of the pharmaceutical studies can be criticised for having too short a duration or for likely incomplete acid suppression. Few trials have specifically studied pediatric populations. Because GERD is a common condition, particularly in young children, the role reflux plays in the worsening of asthma symptoms and the potential benefit on asthma of anti-reflux therapy warrants further exploration. Whether or not treating symptomatic GERD reduces the symptoms and severity of asthma in children, GERD coexisting with asthma should be aggressively treated. GERD symptoms in most patients with or without asthma can be controlled medically with continuous use of proton pump inhibitors such as omeprazole and lansoprazole and to a lesser extent by histamine H(2) receptor antagonists such as famotidine and cimetidine.

Abstract
OBJECTIVES/HYPOTHESIS A major trend in gastroesophageal reflux disease (GERD) is an observed increased prevalence of the problem, with an associated burden on health care resources. There are relatively few objective reports of increasing prevalence of this disease, and there are no epidemiologic reports that discuss changing practice strategies in managing the disease. The clinical problem is of critical importance to practicing otolaryngologists, who manage the impact of GERD on diseases affecting the ear, nose, and throat. The hypothesis of this thesis is that 1) GERD is an increasing problem affecting outpatient office visits over time, and 2) the disease is increasingly managed with prescription pharmacotherapy. STUDY DESIGN Retrospective national medical database review using the National Ambulatory Medical Care Survey. METHODS Twelve years of data (1990-2001) were examined with visits weighted to provide U.S. estimates of care. Average annual frequencies and visit rates were calculated for total visits and by age, sex, race, and physician specialty. Selected issues in GERD treatment were also examined, including prescriptions and physician/patient counseling regarding stress management, tobacco abuse, and diet modification. Trends were reported based on changes in care across three time periods to satisfy statistical significance: 1990 to 1993, 1994 to 1997, and 1998 to 2001. RESULTS Between 1990 and 1993 and 1998 and 2001, there was a significant increase in U.S. ambulatory care visits for GERD, from a rate of 1.7 per 100 to 4.7 per 100. There were no significant changes in race, although there was a small trend toward increased GERD visits in the age group over 44 years old and in the male sex. Office visits to otolaryngologists increased from 89,000 to 421,000 between the time periods of 1990 to 1993 and 1998 to 2001. This also represented a percent increase in office encounters by otolaryngologists compared with visits by all specialties from 2.9% to 4.4%. Over the three time periods, there was a fall in prescriptions for histamine (H2) blockers from 58.1% to 20.7% of total prescriptions. Over the same three time periods, prescriptions of proton pump inhibitors increased from 13.2% to 64.6%. Physician recommendations for over the counter medications fell from 18.8% to 6.6%. Average annual counseling during ambulatory care visits for GERD was assessed for the period from 1998 to 2001 as follows: diet counseling was provided at 27.2% of encounters, tobacco cessation counseling was provided at 3.9%, and stress management was discussed at 3.9%. CONCLUSIONS During the 1990s, there was a substantial increase in the use of ambulatory care services for GERD. Although much of this increase was among the primary care community, otolaryngologists appeared to have an increasingly prominent role in the management of this disease. There have also been dramatic changes in physician prescribing patterns for GERD, with the emergence of the predominant role of proton pump inhibitors. However, the use of physician counseling for lifestyle modification of factors known to affect GERD remains very low. The increasing impact of GERD on physician practice emphasizes the importance of both physician and patient education in the delivery of health care related to this disease.

Abstract
BACKGROUND This multicenter survey includes neonates and infants who underwent surgery for primary gastroesophageal reflux (GER) who presented with supraesophageal symptoms of unknown origin with a minimum of 12 months postoperative follow-up. METHODS A total of 726 patients underwent GER surgery in 10 European Centers in the period 1998-2002. Respiratory symptoms were present in 204 patients (28%); 135 patients (17%) had surgery under 1 year of age, and 46 of them (6.3%) because of respiratory symptoms. Surgery was performed without any previous medical treatment in 10 cases (21%). The type of procedure included 37 complete 360 degrees wraps (80%) (Nissen, 12, and Rossetti, 25) and nine partial wraps (20%) (Thal five, Lortat Jacob one, Toupet one, others two). Gastrostomy was associated in 17 cases (37%) (6 PEG and 11 modified Stamm). No gastric emptying procedures were recorded. RESULTS No major intraoperative complications were reported. Six patients developed complications (13%) and a redo operation was performed in three (6.5%). Respiratory outcome after antireflux surgery was good in 35 patients (76%) and fair with significantly improved respiratory symptoms in 11 (24%). CONCLUSIONS This multicenter survey underlines that GER has to be suspected and aggressively treated in infants with difficult-to-treat supraesophageal symptoms, and also in high-risk cases, in order to prevent major complications.

Abstract
Gastroesophageal reflux (GER) is a potential trigger of asthma. Approximately 77% of asthmatics report heartburn. GER is a risk factor for asthma-related hospitalization and oral steroid burst use. Asthmatics may be predisposed to GER development because of a high prevalence of hiatal hernia and autonomic dysregulation and an increased pressure gradient between the abdominal cavity and the thorax, over-riding the lower esophageal sphincter pressure barrier. Asthma medications may potentiate GER. Potential mechanisms of esophageal acid-induced bronchoconstriction include a vagally mediated reflex, local axonal reflexes, heightened bronchial reactivity, and microaspiration, all resulting in neurogenic inflammation. Anti-reflux therapy improves asthma symptoms in approximately 70% of asthmatics with GER. A 3-month empiric trial of twice-daily proton pump inhibitor given 30 to 60 minutes before breakfast and dinner can identify asthmatics who have GER as a trigger of their asthma.

Abstract
Extraesophageal manifestations of gastroesophageal reflux disease (GERD) are essentially complications of GERD that primarily involve organs that are in proximity to the esophagus. Non-cardiac chest pain (NCCP) is an atypical manifestation of GERD, because symptoms originate in essence from the esophagus. In both atypical and extraesophageal manifestation of GERD frequent heartburn is uncommon and lack of GERD symptoms is not unusual. Esophageal mucosal injury is rarely present making upper endoscopy a low-yield procedure in both conditions. While association with GERD has been commonly reported, the extent of causality remains unknown. In NCCP, the usefulness of the proton pump inhibitor (PPI) test in diagnosing GERD-related NCCP has been established. Similar value in extraesophageal manifestations of GERD has been proposed, but rarely studied. While treatment of extraesophageal manifestations of GERD remains a challenge, PPIs in at least double the standard dose, should be considered for the initial therapy. Properly designed therapeutic studies are still lacking as well as the exact role of antireflux surgery in this patient population.

Abstract
Gastroesophageal reflux disease (GERD) is a common condition which is particularly prevalent in patients with asthma and chronic cough. Physiologic changes caused by asthma and chronic cough promote acid reflux. GERD is also considered by many investigators as a factor contributing to airway inflammation. An etiological relationship between GERD and asthma/chronic cough and vice versa has been supported by a large number of experimental and clinical findings and refuted by others. Although further controlled studies are needed to clarify this relationship, GERD and asthma/chronic cough appear to be linked to each other. The association of GERD with asthma and chronic cough involves nerve reflexes, cytokines, inflammatory and neuroendocrine cells and, in some patients, tracheal aspiration of refluxing gastric fluids. GERD may present with typical symptoms but can also be asymptomatic. Sensitive methods for diagnosing GERD are available, which include esophageal pH monitoring, acid provocative tests, modified barium swallow and endoscopy. Consideration of the association of GERD with asthma and chronic cough is of practical value in the management of chronic cough or asthma resistant to treatment. Treatment of GERD in patients with asthma has been consistently shown to improve respiratory symptoms but not necessarily pulmonary function tests. Surgical treatment can be a useful and cost-effective approach in selected patients with asthma and GERD.

Abstract
BACKGROUND The role of surgery is debated for children with gastroesophageal reflux disease (GERD), particularly when they show atypical symptoms. This study was designed to evaluate the safety and outcome of laparoscopic Nissen-Rossetti fundoplication performed in a selected population of children with gastroesophageal reflux and atypical supraesophageal symptoms. METHODS This prospective study included 595 patients younger than 14 years with GERD who reported recurrent respiratory symptoms and had no benefit from standard medical treatment. Surgery was performed for 48 patients with anatomic anomalies, life-threatening events, or respiratory complications after ineffective medical treatment. The subjective and objective outcomes were evaluated. RESULTS No major intraoperative complications were experienced, and there was no recurrence of gastroesophageal reflux during a postoperative follow-up period of 12 months. The parents' final subjective evaluation of the outcomes 12 months after surgery was positive in 44 cases and negative in 4 cases. CONCLUSIONS Children with difficult-to-treat chronic respiratory symptoms must be evaluated for GERD, even if the need for surgery is low (8%), because complete eradication of reflux is mandatory. Radical treatment of GERD allows the pulmonologist to perform correct respiratory treatment and to prevent the development chronic and life-threatening complications.

Abstract
The intimate anatomical and physiologic relationship between the upper airway and esophagus consists of complex interactions between various muscles and nerves with both voluntary and involuntary patterns of control. Alterations in this harmonic relationship can lead to swallowing abnormalities ranging from dysphagia to gross aspiration, gastroesophageal reflux disease (GERD) and chronic cough. There is a paucity of data regarding pathologic alterations in the upper airway-esophageal relationship in patients with COPD. The association between GERD and respiratory symptoms is well recognized in the setting of asthma; however, the nature of this relationship remains controversial. The association of GERD and COPD is even less clear. A review of the limited data on GERD and swallowing abnormalities in patients with COPD indicate that prevalence of GERD and esophageal disorders in patients with COPD is higher than in the normal population. However, its contribution to respiratory symptoms, bronchodilator use and pulmonary function in patients with COPD remains unknown. Although dysphagia and swallowing dysfunction on videofluoroscopic swallow evaluation are common in patients with COPD, their role as exacerbators of COPD remains to be elucidated. Further clinical research is necessary to evaluate the role of GERD and swallowing dysfunction in both stable and acute exacerbation of COPD.

Abstract
The association between gastroesophageal reflux disease (GERD) and extraesophageal disease is often referred to as extraesophageal reflux (EER). This article reviews EER, discussing epidemiology, pathogenesis, diagnosis, and treatment with a focus on the most studied and convincing EER disorders-asthma, cough, and laryngitis. Although EER comprises a heterogeneous group of disorders, some general characterizations can be made, as follows. First, although GERD's association with extraesophageal diseases is well-established, definitive evidence of causation has been more elusive, rendering epidemiological data scarce. Secondly, regarding the pathogenesis of EER, 2 basic models have been proposed: direct injury to extraesophageal tissue by acid and pepsin exposure or injury mediated through an esophageal reflex mechanism. Third, because heartburn and regurgitation are often absent in patients with EER, GERD may not be suspected. Even when GERD is suspected, the diagnosis may be difficult to confirm. Although endoscopy and barium esophagram remain important tools for detecting esophageal complications, they may fail to establish the presence of GERD. Even when GERD is diagnosed by endoscopy or barium esophagram, causation between GERD and extraesophageal symptoms cannot be determined. Esophageal pH is the most sensitive tool for detecting GERD, and it plays an important role in EER. However, even pH testing cannot establish GERD's causative relationship to extraesophageal symptoms. In this regard, effective treatment of GERD resulting in significant improvement or remission of the extraesophageal symptoms provides the best evidence for GERD's pathogenic role. Finally, EER generally requires more prolonged and aggressive antisecretory therapy than typical GERD requires.

Abstract
For more than a decade, investigations have examined the association between asthma and gastroesophageal reflux (GER), and have demonstrated that the presence of esophageal acid events is associated with respiratory symptoms. The most current research shows that GER is prevalent in patients with asthma, that esophageal acid may alter bronchial hyperresponsiveness, and that medical or surgical GER therapy may improve asthma outcome in selected asthma patients. Further research will build on our current knowledge base and, hopefully, enable us to better identify those patients with asthma who will most benefit from reflux therapy.

Abstract
OBJECTIVE To assess whether severe gastroesophageal reflux (GER) is associated with abnormalities in lung function including measures of lung volume and gas diffusion. METHODS Data from 147 patients with obesity (body mass index [BMI] range, 31.7 to 70 kg/m(2)) who presented for obesity surgery was analyzed retrospectively. A questionnaire was completed preoperatively that included a history of GER, frequency and severity of symptoms, investigations, and medications used. A history of lung disease, sleep-disordered breathing, and smoking also was obtained. A physician who was blinded to lung function graded GER severity prospectively by the results of pH monitoring and/or gastroscopy, and medication use. Spirometry, lung volumes, and gas transfer were measured preoperatively. RESULTS Patients with severe GER had reduced levels of the diffusing capacity of the lung for carbon monoxide (DLCO) [21.1 mL/min/mm Hg; 95% confidence interval (CI), 18.9 to 23.2], as measured by CO transfer, compared with those patients without GER (26.3 mL/min/mm Hg; 95% CI, 24.4 to 28.2; p = 0.001). This remained significant after adjusting for age, gender, BMI, and smoking history. Gas transfer corrected for lung volume also was reduced in the group with severe GER (4.6 mL/min/mm Hg per L; 95% CI, 4.3 to 4.9) compared to the group without GER (5.3 mL/min/mm Hg per L; 95% CI, 5.1 to 5.5; p = 0.001). There was no significant difference in other measures of lung function. CONCLUSIONS Severe GER is associated with an impairment of gas exchange. This may be due to microaspiration of gastric acid or fluid into the airways.

Abstract
BACKGROUND A causal relationship between gastroesophageal reflux (GER) and asthma has been suggested. Should this be the case, one could expect treatment of GER to diminish bronchial sensitivity. There has been a lack of trials evaluating the efficacy of antireflux surgery on airway reactivity. OBJECTIVES To investigate the correlation between GER and bronchial responsiveness, and to determine the efficacy of Nissen fundoplication on bronchial responsiveness and pulmonary function. METHODS A methacholine inhalation challenge was performed on 15 consecutive GER patients preoperatively and approximately 5 months after Nissen fundoplication. Airway responsiveness was quantified with a dose-response slope (DRS), calculated by dividing the decrease in FEV(1) (%) with the dose of methacholine administered (micromoles). RESULTS A positive correlation between the severity of distal esophageal reflux and bronchial responsiveness was found (r = 0.83, p < 0.001). There was an improvement in FEV(1) after fundoplication (p = 0.03). All 3 asthmatic patients participating in the study presented with bronchial hyperresponsiveness (BHR) which improved clearly in all of these patients after fundoplication. This resulted in an apparent trend for DRS to improve when the entire study population was considered (p = 0.12). CONCLUSIONS According to the current study there seems to be a positive correlation between the severity of distal esophageal reflux and bronchial responsiveness. These data suggest that operative treatment of GER may ameliorate BHR in asthmatic patients. Moreover, the results of the present study suggest that fundoplication may improve pulmonary function in patients with GER.
