OBJECTIVE: To review the clinical presentation, diagnosis, and treatment options available for management of extraesophageal manifestations of gastroesophageal reflux disease (GERD) and to compare the most recent technological advances to the existing guidelines. SUMMARY BACKGROUND DATA: Extraesophageal manifestations of GERD include cough, laryngopharyngeal reflux (LPR), and asthma. Recent advances in diagnostic modalities may have outpaced the existing diagnostic and therapeutic clinical guidelines...

OBJECTIVES: To determine the patterns and proximity of reflux events in patients with adult-onset asthma (AOA) using hypopharyngeal multichannel intraluminal impedance (HMII) and to assess outcomes of antireflux surgery (ARS) in patients with AOA. DESIGN Retrospective review of prospectively collected data. SETTING: University hospital. PATIENTS, INTERVENTIONS, AND OUTCOMES: All patients with AOA referred to our testing center underwent HMII, and those with abnormal proximal exposure, defined as laryngopharyngeal reflux at least once a day and/or high esophageal reflux at least 5 times a day, subsequently underwent ARS...

BACKGROUND: The current diagnostic algorithms for chronic cough require the establishment of the primary presumptive causes followed by the confirmation of diagnosis with the specific therapies. The aim of the study was to investigate the discrepancy between presumptive and definite causes and its clinical implication. METHODS: A total of 109 patients with chronic cough underwent laboratory investigations to identify the cause of cough; including sinus computerized tomography (if needed), histamine bronchial provocation, induced sputum cytology and 24-hour esophageal pH or multi-channel intraluminal impedance combined with pH monitoring...

BACKGROUND: Pepsin has been proposed as a biomarker of reflux-related lung disease. The goal of this study was to determine (i) if there is a higher reflux burden as measured by pH-MII in patients that are pepsin positive in the lung, and (ii) the sensitivity of pepsin in predicting pathologic reflux by pH, MII, and EGD. METHODS: We recruited children between the ages of 1-21 with chronic cough or asthma undergoing bronchoscopy, esophagogastroduodenoscopy (EGD), and multichannel intraluminal impedance (pH-MII) probe placement...

COMPARATIVE STUDY

INTRODUCTION: Gastroesophageal reflux (GER) is associated with respiratory symptoms. The link between non-acid GER and the pathogenesis of respiratory disease has been demonstrated. Esophageal multichannel intraluminal impedance (MII) is able to detect non-acid and alkaline GER, as well as reflux height. The objective of the study was to compare the diagnostic effectiveness of dual-channel pH-meter and MII. PATIENTS AND METHODS: A prospective study was conducted on patients diagnosed with uncontrolled asthma, persistent cough, or chronic laryngitis...

BACKGROUND: Laryngopharyngeal reflux (LPR) can cause atypical symptoms, asthma, and pulmonary fibrosis. The aim of this study was to establish the normative data for LPR using hypopharyngeal multichannel intraluminal impedance-pH (HMII). METHODS: Asymptomatic subjects underwent endoscopy followed by 24-h HMII using a specialized impedance catheter configured to detect LPR before and after a 2-week course of proton pump inhibitors (PPI). Subjects were excluded if they had esophageal pathology or a positive DeMeester score...

BACKGROUND: Although symptom outcomes following laparoscopic fundoplication have been adequately evaluated in the past, comparative subjective data of laparoscopic Nissen and Toupet fundoplications are scarce. Multichannel intraluminal impedance monitoring (MII) has not been used so far for comparison of objective data. METHODS: One hundred patients with documented chronic gastroesophageal reflux disease (GERD) were randomly allocated to either floppy Nissen fundoplication (group I, n = 50) or Toupet fundoplication (group II, n = 50)...

BACKGROUND AND OBJECTIVE: The aim of this study was to explore the pathogenesis of chronic cough caused by non-acid reflux. METHODS: Seven patients with chronic cough due to non-acid reflux, 12 patients with chronic cough due to acid reflux, 10 patients with gastro-oesophageal reflux disease without cough and 12 healthy volunteers were recruited for the study. All subjects underwent oesophageal multi-channel intraluminal impedance measurements combined with pH monitoring, and assessment of cough reflex sensitivity to capsaicin and induced sputum cytology...

OBJECTIVES: To evaluate the association between the frequency of acid reflux (AR) and weakly acid reflux (WAR) and specific respiratory symptoms (RS) in childhood. STUDY DESIGN: We retrospectively reviewed medical records of children with difficult-to-treat RS, not under acid suppressive therapy, and with a positive multiple intraluminal esophageal impedance (pH/MII) monitoring. To discriminate children with prevalent AR and WAR events, a ROC curve was designed and the distribution of the different RS in children with prevalent AR or WAR events was analyzed...

BACKGROUND & AIMS: In a group of children with suspected pulmonary aspiration, we aimed to describe the type and physical characteristics of gastro-oesophageal reflux (GOR) episodes, and to determine their correlation with the lipid-laden macrophage (LLM) content in bronchoalveolar lavage (BAL). PATIENTS AND METHODS: Twenty-one children with a diagnosis of bronchial asthma, recurrent lung consolidations and recurrent laryngotracheitis underwent 24-h multichannel intraluminal impedance and pH (MII-pH) monitoring, fibreoptic bronchoscopy and BAL...

BACKGROUND: Gastroesophageal reflux is implicated in the pathogenesis of asthma and chronic cough. To date most studies have focused on acid reflux measured by pH below the upper esophageal sphincter (UES). The aim of this study was to assess the relationship between cough and reflux through the UES into the pharynx. METHODS: Thirty-seven patients with asthma (19) and chronic cough (18) were recruited from the respiratory clinic. Reflux was monitored using a combined multichannel intraluminal impedance and pH probe by detecting (1) bolus reflux episodes within the esophagus and in the pharynx and (2) acidic reflux episodes within the esophagus and in the pharynx...

OBJECTIVES: To determine the proportion of acid and nonacid reflux events in children with asthma suspected to have gastroesophageal reflux (GER) using combined impedance-pH monitoring, and to determine the symptom index (SI) for nonacid and acid reflux events. STUDY DESIGN: This was a prospective study of children with asthma (age 5 months to 6 years) referred for evaluation of GER. Exclusion criteria were congenital anomalies, cerebral palsy, mental retardation, and cardiac disease...

REVIEW
R C Heading
In Western populations, many individuals with symptoms of gastro-oesophageal reflux disease (GERD) do not bother to seek medical attention because their symptoms are mild and acceptably controlled by self-medication. Among those who do consult physicians, only a minority present with the classical clinical symptoms of heartburn and regurgitation: more often the pattern is a nonspecific combination of upper gastrointestinal complaints that do not permit confident clinical diagnosis. Oesophagitis is now found in less than 50% of GERD patients and those without oesophagitis are sometimes said to have 'non-erosive reflux disease'...
