Abstract
STUDY OBJECTIVES The relationship between obstructive sleep apnea (OSA) and gastroesophageal reflux disease (GERD) is complex. We aimed to determine the association of self-reported and objective sleep parameters with diverse manifestations of the GERD spectrum. METHODS We prospectively recruited 561 individuals who underwent an electrocardiogram-based cardiopulmonary coupling for OSA screening during a health check-up. All participants received the Reflux Disease Questionnaire and an upper endoscopy to determine the presence of troublesome reflux symptoms and erosive esophagitis (EE). Sleep quality was evaluated by the Pittsburgh Sleep Quality Index and sleep dysfunction was defined as a Pittsburgh Sleep Quality Index score > 5. OSA was defined as a cardiopulmonary coupling-derived apnea-hypopnea index exceeding 15 events/h. Comparisons were made between participants on the GERD spectrum with respect to their various self-reported and objective sleep parameters. RESULTS Among the 277 patients with GERD (49.4%), 198 (35.3%) had EE. Patients with GERD had higher PSQI scores (6.99 ± 3.97 vs 6.07 ± 3.73, P = .005) and a higher prevalence of sleep dysfunction (60.6% vs 49.6%, P = .009). Patients with EE had a higher prevalence of OSA (42.9% vs 33.9%, P = .034). Along the GERD spectrum, symptomatic patients with EE had the highest PSQI scores and prevalence of sleep dysfunction (70.7%), while asymptomatic patients with EE had the highest prevalence of OSA (44%). CONCLUSIONS Our findings indicate a high prevalence of sleep dysfunction among individuals with GERD. Furthermore, patients on the GERD spectrum are prone to experiencing a range of self-reported and objective sleep disturbances. CITATION Hu K-Y, Tseng P-H, Hsu W-C, et al.

Abstract
STUDY OBJECTIVES To objectively characterize (1) the relationship between gastroesophageal reflux disease (GERD) and sleep quality, and (2) the influence of sleep position on this relationship, using in-laboratory polysomnography. METHODS We retrospectively analyzed first-night diagnostic in-laboratory polysomnography data for 3411 patients (median age 55 years; 48% male). Medication use and medical condition data were obtained through self-reported questionnaires. Associations between sleep quality and the presence of GERD, and the influence of sleep position on these associations, were analyzed using multivariable linear regression models. RESULTS After adjusting for age, sex, body mass index, and relevant comorbidities, GERD was associated with a 3.0% decrease in sleep efficiency, 8.8-minute increase in wake after sleep onset, 24.4-minute increase in rapid eye movement (REM) latency, 13.4-minute decrease in total sleep time, 1.4% decrease in %REM sleep, and 1.5% increase in %N3 sleep. Having both GERD and the majority of sleep on the right side was associated with an 8.6% decrease in sleep efficiency, 27.5-minute increase in wake after sleep onset, 35.6-minute decrease in total sleep time, 2.1% decrease in %REM sleep, and 3.5% increase in %N3 sleep. Having both GERD and the majority of sleep on the left side was associated with an 8.7-minute increase in sleep onset latency. CONCLUSIONS GERD is associated with an impairment in objective sleep quality. These associations were more pronounced in right-sided sleep and mostly ameliorated in left-sided sleep. Physicians should recognize the potential for poor sleep quality in patients with GERD and the effect of body position on this relationship. CITATION Gurges P, Murray BJ, Boulos MI.

J Neurogastroenterol Motil 2021; 27:215-222. [PMID: 32759463 PMCID: PMC8026368 DOI: 10.5056/jnm20071] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/10/2020] [Revised: 06/01/2020] [Accepted: 06/15/2020] [Indexed: 12/13/2022] Open
Abstract
Background/Aims As there is insufficient evidence for a relationship between gastroesophageal reflux disease (GERD) and obstructive sleep apnea (OSA), we investigated whether OSA diagnosed by polysomnography (PSG) is related to GERD. Methods A total of 402 subjects was evaluated. Overnight PSG was performed and a few questionnaires on GERD, anxiety, depression, and daytime sleepiness were administered. An apnea-hypopnea index < 5 was the classification criterion for subjects without OSA. Subjects with heartburn or acid regurgitation at least once a week were classified as having GERD. Results Among the 402 subjects, 318 had OSA and 84 did not. The prevalence of GERD was 12.9% among patients with OSA and 10.7% among those without (P = 0.590). The prevalence of GERD did not correlate with OSA severity (P = 0.474). Patients with OSA with GERD had higher Stanford Sleepiness Scale (P = 0.004), Epworth Sleepiness Scale (P = 0.001), and depression (P < 0.001) scores than patients with OSA without GERD. Subjects with nocturnal gastroesophageal reflux symptoms had a higher body mass index, waist-to-height ratio, and waist circumference-to-height index than those without symptoms. Multiple logistic regression showed that higher Epworth Sleepiness Scale and depression scores were independent factors associated with GERD in patients with OSA. Conclusions The prevalence of GERD in patients with OSA was 12.9%. The prevalence of GERD did not correlate with OSA severity. Daytime sleepiness and depression seem to be associated with GERD in patients with OSA, while nocturnal reflux symptoms seem to be related to obesity in OSA.

Temporal Association Between Respiratory Events and Reflux in Patients With Obstructive Sleep Apnea and Laryngopharyngeal Reflux. J Clin Sleep Med 2019; 15:1397-1402.

Abstract
STUDY OBJECTIVES The aim of the current study was to test the hypothesis that there is a temporal correlation between reflux episodes and respiratory events in patients with laryngopharyngeal reflux and obstructive sleep apnea. METHODS Adults with clinically diagnosed laryngopharyngeal reflux confirmed by two validated instruments (reflux symptom index ≥ 13 and reflux finding score ≥ 7) and obstructive sleep apnea (OSA) underwent full polysomnography with concomitant and synchronized multichannel intraluminal impedance-pH esophageal monitoring. The apnea-hypopnea and arousal indexes that occurred 15, 30, and 45 minutes before and after each reflux episode were recorded and compared to full-night apnea and hypopnea and arousal index. RESULTS We studied 27 patients (14 males, age 51.7 ± 9.1 years, body mass index 32.4 ± 4.2 kg/m²) with laryngopharyngeal reflux (reflux symptom index 16 ± 2 and reflux finding score 12 ± 3) and OSA (apnea-hypopnea index = 32.3 ± 28.4 events/h). We evaluated 102 reflux episodes. Almost half of the reflux episodes occurred while awake (43.1%) and only five reflux episodes (4.9%) occurred during an obstructive respiratory event. The apnea and hypopnea and arousal indexes 15, 30, and 45 minutes before and after reflux episodes were lower than full-night apnea and hypopnea and arousal indexes, respectively. CONCLUSIONS Among patients with well-established laryngopharyngeal reflux and OSA, there is no temporal association between reflux and obstructive respiratory events. Even though the data comprised a small sample size, it seems that a more complex mechanism is involved with these two highly prevalent diseases.

Abstract
Sleep dysfunction is an epidemic affecting a large portion of the adult population. Recent studies have linked sleep dysfunction with an upregulation of proinflammatory cytokines (eg, tumor necrosis factor-α, interleukin-1 and interleukin-6), the implications of which can have a profound impact on a variety of gastrointestinal disease. In particular, sleep dysfunction seems to accelerate disease states characterized by inflammation (eg, gastroesophageal reflux disease, irritable bowel syndrome and functional dyspepsia, chronic liver disease, inflammatory bowel disease, and colorectal cancer). This article evaluates the complex interplay between sleep dysfunction and gastrointestinal health and disease.

Abstract
STUDY OBJECTIVES This is the first study to compare reflux events during wake and sleep in obese and non-obese individuals with obstructive sleep apnea (OSA) and obese individuals without OSA. The primary aim of the study was to investigate any additive effect of OSA on gastroesophageal reflux (GER) above that of obesity. METHODS Twenty obese individuals (body mass index, BMI > 30 kg/m(2)), 9 non-obese individuals (BMI < 30 kg/m(2)) with moderate-to-severe OSA, and 17 obese control subjects (BMI > 30 kg/m(2)) underwent high-resolution esophageal manometry, 24-h esophageal pH-impedance monitoring, and in-laboratory polysomnography. RESULTS Mean body mass index was 40 ± 6 and 27 ± 4 kg/m(2) for the obese and non-obese OSA groups, respectively, and 34 ± 5 kg/m(2) for the obese control group. Apnea-hypopnea index (AHI) was 50 ± 30 and 30 ± 25 per hour for the obese and non-obese OSA groups (p > 0.05), significantly higher than that of the obese control group (3 ± 3 per hour, p < 0.05). The two obese groups did not show any significant differences in the total number of acidic reflux events (41 ± 20 vs 28 ± 16); however, the obese OSA group had a greater number of acidic reflux events compared to the non-obese OSA group (22 ± 12 events, p < 0.05). In multivariate analysis, BMI significantly predicted number of acidic reflux events (r(2) = 0.16, p = 0.01) during the 24-h period; however, AHI showed no significant association with any measure of GER severity. CONCLUSIONS This study confirms an important role for obesity, rather than OSA per se in the relationship between OSA and GER.

Abstract
STUDY OBJECTIVES Nocturnal gastroesophageal reflux (nGER) is common among patients with obstructive sleep apnea (OSA). Previous studies demonstrated that continuous positive airway pressure (CPAP) reduces symptoms of nGER. However, improvement in nGER symptoms based on objective CPAP compliance has not been documented. We have examined the polysomnographic characteristics of patients with nGER and OSA and looked for association of OSA severity and CPAP compliance with improvement in nGER symptoms. METHODS We interviewed 85 veterans with OSA to assess their daytime sleepiness (Epworth Sleepiness scale [ESS]) and nGER symptom frequency after their polysomnography and polysomnographic data were reviewed. At 6 months' follow-up, ESS score, nGER score, and CPAP machine compliance data were reassessed. Data from 6 subjects were dropped from final analysis due to their initiation of new medication for nGER symptom since the initial evaluation. RESULTS Sixty-two of 79 (78%) patients complained of nGER symptoms during initial visit. At baseline, nGER score was correlated with sleep efficiency (r = 0.43), and BMI correlated with the severity of OSA (r = 0.41). ESS and nGER improved (p < 0.0001) in all patients after 6 months, but more significantly in CPAP compliant patients. A minimum CPAP compliance of 25% was needed to achieve any benefit in nGER improvement. CONCLUSIONS Nocturnal gastroesophageal reflux is common among patients with OSA which increases sleep disruption and worsens the symptoms of daytime sleepiness. CPAP therapy may help improve the symptoms of both nocturnal acid reflux and daytime sleepiness, but adherence to CPAP is crucial to achieve this benefit.

Abstract
STUDY OBJECTIVES To investigate the potentially bidirectional association between gastroesophageal reflux symptoms (GERS) and sleep disturbances/ insomnia disorders. METHODS We assessed the incidence of new-onset of self-reported GERS, sleep disturbances, and insomnia disorders in a population-based longitudinal cohort study (HUNT), performed in Nord-Trøndelag County, Norway. Modified Poisson regression was used to estimate risk ratios (RRs) with 95% confidence intervals (CIs), adjusted for sex, age, body mass index, tobacco smoking, educational level, anxiety, and depression. RESULTS The study cohort included the 25,844 participants of the HUNT study who responded to health questionnaires in both 1995-1997 and 2006-2009. New-onset GERS, sleep disturbances, and insomnia disorders was reported in 396 (2%), 2,598 (16%), and 497 (3%) participants, respectively. Persistent sleep disturbances were associated with new-onset GERS (RR: 2.70, 95% CI: 1.93-3.76), persistent insomnia disorders were associated with new-onset GERS (RR: 3.42; 95% CI: 1.83-6.39) and persistent GERS was associated with new-onset sleep disturbances (RR: 1.41; 95% CI: 1.14-1.75). CONCLUSIONS Sleep disturbances and GERS seem to be bidirectionally associated, and sleep disturbances seem to be a stronger risk factor for GERS than the reverse.

Abstract
This study was designed to assess evidence for an association between the treatment of gastroesophageal reflux disease (GERD) with proton pump inhibitors (PPIs) and improvement in obstructive sleep apnea (OSA). We conducted a systematic review and meta-analysis of randomized controlled trials and prospective cohort studies to evaluate the treatment effect of PPIs on OSA symptoms and indices in patients with GERD. EMBASE, MEDLINE, the Cochrane Central Register of Controlled Trials, the Cochrane Database of Systematic Reviews, and ClinicalTrials.gov were reviewed up to October 2014. From 238 articles, two randomized trials and four prospective cohort studies were selected. In four cohort studies there were no differences in the apnea-hypopnea indices before and after treatment with PPIs (standard mean difference, 0.21; 95% confidence interval, -0.11 to 0.54). There was moderate heterogeneity among these studies. Two cohort studies revealed significantly decreased apnea indices after treatment (percent change, 31% and 35%), but one showed no significant difference. A significant improvement in the Epworth Sleepiness Scale was observed in three cohort studies and one trial. The frequency of apnea attacks recorded in diaries was decreased by 73% in one trial. In conclusion, available studies do not provide enough evidence to make firm conclusions about the effects of PPI treatment on OSA symptoms and indices in patients with concomitant GERD. Controlled clinical trials with larger sample sizes are needed to evaluate these associations. We recommend PPIs in OSA patients with concomitant GERD to treat reflux symptoms. This treatment may improve the quality of sleep without any effect on apnea-hypopnea indices.

Abstract
OBJECTIVES To describe the proportion of at-risk World Trade Center (WTC)-exposed rescue/recovery workers with polysomnogram-confirmed obstructive sleep apnea (OSA) and examine the relationship between WTC exposure, physician-diagnosed gastroesophageal reflux disease (GERD), and rhinosinusitis and OSA. METHODS A total of 636 male participants completed polysomnography from September 24, 2010, to September 23, 2012. Obstructive sleep apnea was classified as mild, moderate, or severe. Associations were tested using nominal polytomous logistic regression. RESULTS Eighty-one percent of workers were diagnosed with OSA. Using logistic regression models, severe OSA was associated with WTC exposure on September 11, 2001 (odds ratio, 1.91; 95% confidence interval, 1.15 to 3.17), GERD (odds ratio, 2.75; 95% confidence interval, 1.33 to 5.70), and comorbid GERD/rhinosinusitis (odds ratio, 2.31; 95% confidence interval, 1.22 to 4.40). CONCLUSIONS We found significant associations between severe OSA and WTC exposure, and with diseases prevalent in this population. Accordingly, we recommend clinical evaluation, including polysomnography, for patients with high WTC exposure, other OSA risk factors, and a physician diagnosis of GERD or comorbid GERD and rhinosinusitis.

Abstract
Background Gastroesophageal reflux is overrepresented in people with obstructive sleep apnea (OSA) and it has been suggested that OSA worsens gastroesophageal reflux symptoms. Aggravated reflux might lead to an increased risk of Barrett’s esophagus. Aim To assess the association between sleep apnea symptoms and Barrett’s esophagus. Methods Included in a case-control study in Brisbane, Australia were 237 patients with histologically confirmed Barrett’s esophagus and 247 population controls. The controls were randomly selected from the electoral roll and frequency-matched to the cases by age and sex. Information on OSA symptoms (excessive daytime sleepiness and sleep related apnea symptoms), gastroesophageal reflux symptoms and anthropometric measures were collected through interviews and written questionnaires. Multivariable logistic regression provided odds ratios (OR) and 95% confidence intervals (CI), adjusted for potential confounding by BMI and gastroesophageal reflux. Results The prevalence of Barrett’s esophagus was higher among people with excessive daytime sleepiness than those without (24% vs. 18%; p-value 0.1142) and in participants with sleep-related apnea symptoms (20% vs. 13%; p-value 0.1730). However, there were non-significantly increased ORs of Barrett’s esophagus among people with excessive daytime sleepiness (OR 1.42, 95% CI 0.90–2.34) and sleep related apnea symptoms (OR 1.32, 95% CI 0.74–2.36) when adjusting for age, sex and BMI. After further adjustment for gastroesophageal reflux symptoms, the point ORs were no longer increased (OR 1.02, 95% CI 0.61–1.70 for daytime sleepiness and OR 0.72, 95% CI 0.38–1.38 for sleep related apnea symptoms). Conclusions Symptoms of OSA are possibly associated with an increased risk of Barrett’s esophagus, an association that appears to be mediated entirely by gastroesophageal reflux.

Abstract
BACKGROUND Up to half of gastroesophageal reflux disease (GERD) patients report having heartburn that awakens them from sleep during the night. Recumbent-awake and conscious awakenings from sleep during the night are commonly associated with acid reflux events. The aim of the study was to assess the effect of esomeprazole 40 mg once daily on nighttime acid reflux, frequency of conscious awakenings associated with acid reflux and the recumbent-awake period. METHODS Patients with heartburn and/or regurgitation at least three times a week were eligible for this study. All patients underwent upper endoscopy and were evaluated by demographic, Epworth Sleepiness scale, Berlin and GERD symptom checklist questionnaires. Subjects then underwent esophageal pH testing concomitantly with an actigraphy. All subjects were given esomeprazole 40 mg once daily for 7 days and completed a daily symptom record diary. On day 7, subjects repeated the pH test with actigraphy. KEY RESULTS Twenty patients (mean age of 48.95 ± 18.69, age range 20-81 years) were enrolled. Esophageal acid exposure parameters, during recumbent-awake, recumbent-asleep, and conscious awakenings were significantly improved on last day of treatment as compared to baseline (p < 0.05). However, the frequency and duration of conscious awakenings and duration of recumbent-awake period did not improve as compared to baseline (p > 0.05). CONCLUSIONS & INFERENCES While esomeprazole significantly reduced esophageal acid exposure during conscious awakenings and recumbent-awake and asleep periods, it did not decrease the number and duration of conscious awakening or duration of recumbent-awake period.

Abstract
OBJECTIVE The pathogenetic relationship underlying the high prevalence of gastroesophageal reflux disease (GERD) in patients with obstructive sleep apnea (OSA) remains unclear. In addition, GERD has not been adequately assessed by endoscopy in patients with OSA. The purpose of this study was to use endoscopy to investigate potential interactions among reflux esophagitis, hiatal hernia (HH) and OSA. MATERIAL AND METHODS A total of 243 consecutive male Japanese participants who underwent both overnight ambulatory polygraphic monitoring and esophagogastroduodenoscopy were retrospectively evaluated in a cross-sectional study. The prevalence and severity of HH and reflux esophagitis were assessed according to the Los Angeles classification and the Makuuchi classification, respectively. Associations among reflux esophagitis, HH and OSA were examined by univariate and multivariate analyses. RESULTS OSA was diagnosed in 98 individuals (40.3%). Endoscopy-confirmed esophagitis (p = 0.027) and HH (p < 0.001) were significantly more prevalent among patients with OSA. Multivariate regression model analysis adjusted for age, body mass index, visceral obesity represented by waist circumference, presence of OSA, concurrence of OSA and HH, smoking, and alcohol consumption yielded OSA as the only variable significantly associated with HH (odds ratio [OR], 2.60; 95% confidence interval [CI], 1.35-4.99; p = 0.004), while concurrence of OSA and HH was related to reflux esophagitis (OR, 3.59; CI, 1.87-6.92; p < 0.001). CONCLUSIONS OSA was associated with HH and concurrent OSA and HH with reflux esophagitis in male Japanese patients with OSA. Our results support the hypothesis that complicating HH may link reflux esophagitis to OSA.

Abstract
Obstructive sleep apnea syndrome (OSAS) is a common disorder characterized by repetitive episodes of breathing cessation due to complete or partial collapse of the upper airway therefore affecting ventilation. It is quite common, with a prevalence of about 2-4%, has a strong genetic component, and creates a proinflammatory state with elevated TNFα and other cytokines. If untreated, OSA can lead to significant neurological problems that include stroke, cognitive decline, depression, headaches, peripheral neuropathy, and nonarteritic ischemic optic neuropathy (NAION). Treatment reverses some of these neurological problems. Treatment includes continuous positive airway pressure and its variants, oral appliances, weight loss, upper airway surgery, and rarely maxillofacial procedures. Other sleep breathing disorders such as hypoventilation, central sleep apnea, complex sleep apnea, and Cheyne-Stokes respiration are less common and are sometimes associated with neuromuscular disorders causing diaphragmatic paralysis, but can also be seen in opiate exposure and severe obesity.

Abstract
OBJECTIVE Studies on the association between gastroesophageal reflux disease (GERD) and sleep apnea syndrome (SAS) have reported conflicting results, and attention has not been paid to the relationship between GERD and other sleep disorders. The aim of the study was to evaluate the relationship between GERD and various aspects of sleep disturbances. METHODS A total of 564 subjects who were referred to a sleep laboratory were enrolled in the study. They underwent nocturnal polysomnography (NPSG), and they were asked to complete a GERD questionnaire. The questionnaire consisted of 14 items, and included questions on seven reflux symptoms, namely, heartburn, acid regurgitation, chest pain, hoarseness, globus sensation, coughing and epigastric soreness. Subjects reporting heartburn or acid regurgitation at least once a week were classified as having GERD. RESULTS Among 564 participants, 51 subjects (9.0%) were diagnosed as having GERD. GERD patients had higher scores in Beck depression inventory (p<.01), Epworth sleepiness scale (p=.03), Pittsburg sleep quality index (p<.01), more spontaneous arousals in NPSG, and more alcohol consumption than non-GERD patients. There was no association between presence of GERD, SAS-related variables, and body mass index (BMI). GERD was significantly associated with poor sleep quality (adjusted OR, 3.5; 95% CI, 1.3-9.3) and depressed mood (adjusted OR, 2.8; 95% CI, 1.5-5.3). CONCLUSION Poor subjective sleep and depressive symptoms are associated with the presence of GERD with no association between SAS, BMI and GERD. In managing patients with GERD, psychiatric and sleep symptoms need to be evaluated and appropriately treated.

Abstract
OBJECTIVE Gastroesophageal reflux disease (GERD) and obstructive sleep apnea (OSA) often coexist. We sought to determine the presence and direction of any association between GERD and sleep events in patients with OSA. MATERIALS AND METHODS We conducted a case-crossover study among 18 patients with known OSA and GERD. All study patients underwent overnight simultaneous polysomnography and esophageal pH monitoring. A series of case-crossover analyses was conducted by defining each of the sleep (i.e. arousal, awakening, and apnea) and gastroesophageal reflux (GER) events as the outcome in turn. Respective control time points were randomly selected in all eligible control periods. When a sleep event was the outcome, the GER event was the exposure of interest. When GER was the outcome, each sleep event was assessed as the exposure individually. Conditional logistic regression models were used to estimate odds ratios (ORs) and 95% confidence intervals (CIs). RESULTS Both awakenings and arousals were significantly associated with the subsequent onset of a GER event. The OR for a GER event following an awakening was 5 (95% CI 3.6-6.9) and for a GER event following an arousal was 2.5 (95% CI 1.8-3.4). Apnea did not lead to GER (OR 1.0, 95% CI 0.8-1.4). GER was not more commonly observed before any of the sleep events compared with control periods without sleep events. CONCLUSION In patients with coexisting GERD and OSA, both awakening and arousal preceded GER events, but GER does not appear to precipitate sleep-related events.

Abstract
Background/Aims The aim of this study is to investigate the reflux patterns in patients with galbladder stone and the change of reflux patterns after cholecystectomy in such patients. Methods Fourteen patients with cholecystolithiasis and a control group including 10 healthy control subjects were enrolled in this prospective study. Demographical findings, reflux symptom score scale and 24-hour impedance pH values of the 14 cholecystolithiasis cases and the control group were evaluated. The impedance pH study was repeated 3 months after cholecystectomy. Results Age, gender, and BMI were not different between the two groups. Total and supine weakly alkaline reflux time (%) (1.0 vs 22.5, P = 0.028; 201.85 vs 9.65, P = 0.012), the longest episodes of total, upright and supine weakly alkaline reflux mediums (11 vs 2, P = 0.025; 8.5 vs 1.0, P = 0.035; 3 vs 0, P = 0.027), total and supine weakly alkaline reflux time in minutes (287.35 vs 75.10, P = 0.022; 62.5 vs 1.4, P = 0.017), the number of alkaline reflux episodes (162.5 vs 72.5, P = 0.022) were decreased with statistical significance. No statistically significant difference was found in the comparison of symptoms between the subjects in the control group and the patients with cholecystolithiasis, in preoperative, postoperative and postcholecystectomy status. Conclusions Significant reflux symptoms did not occur after cholecystectomy. Post cholecystectomy weakly alkaline reflux was decreased, but it was determined that acid reflux increased after cholecystectomy by impedance pH-metry in the study group.

Abstract
BACKGROUND AND AIM Gastroesophageal reflux is frequently associated with sleep-related breathing disorders. We aimed to evaluate the prevalence of acid reflux in patients with sleep-related breathing disorders, their clinical response to proton-pump inhibitor (PPI) treatment, and to identify predictive response factors to this treatment. METHODS Prospective study among patients attending a sleep clinic. Evaluation of typical and atypical gastroesophageal reflux symptoms, simultaneous 24 h dual-channel pH monitoring and polysomnography were performed in all patients. Patients were treated with pantoprazole. After 3-6 months clinical response was evaluated, and pHmetry and polysomnography repeated. Clinical response was defined in terms of snore, apnea and somnolence grading. Improvement in polysomnography was defined by the Stanford criteria. RESULTS One hundred and ninety-nine patients were included. Abnormal reflux levels were detected in the distal esophagus in 72% of patients, and in the proximal esophagus in 46%. Clinical or polysomnographic response to PPI treatment was found in 78% of patients. Pretreatment pHmetry was a significant predictor of success: 67% of responders had pathological proximal pHmetry (vs. 33% of nonresponders; P<0.001), and 55% also had pathological distal pHmetry (P<0.05). Age, sex, BMI, alcohol or tobacco abuse, typical or atypical gastroesophageal reflux symptoms, severity of sleeping disorder, and polysomnography were not predictive of outcome. CONCLUSIONS Patients with sleep-related breathing disorders have an increased prevalence of gastroesophageal reflux disease. They may be successfully treated with PPIs, particularly in patients with an abnormal proximal esophageal pHmetry.

Abstract
BACKGROUND A significant increase in oesophageal acid exposure during early recumbent period has been demonstrated. AIM To determine if acid reflux during the early recumbent period occurs in the recumbent-asleep or recumbent-awake period using a novel integrative actigraphy and pH programme. METHOD Thirty-nine subjects with heartburn at least three times a week were included. Subjects underwent pH testing concomitantly with actigraphy. Simultaneously recorded actigraphy and pH data were incorporated using a novel integrative technique to determine sleep and awake periods. Characteristics of acid reflux were compared between the recumbent-awake and recumbent-asleep periods. RESULTS Seventeen (44.7%) subjects had acid reflux events during recumbent-awake period as compared to seven (18.4%) in the corresponding recumbent-asleep period (P = 0.046). The mean number of acid reflux events in recumbent-awake period was significantly higher than in the corresponding recumbent-asleep period (8.1 +/- 4.4 vs. 3.2 +/- 1.5, P < 0.001). In the recumbent-awake period, 38.4% of acid reflux events were associated with GERD-related symptoms as compared with 3.7% of acid reflux events during the corresponding recumbent-asleep period (P = 0.01). CONCLUSION Increased acid reflux in the early recumbent period occurs primarily during the recumbent-awake and not during the recumbent-asleep period.

Abstract
PURPOSE Obstructive sleep apnea (OSA) is associated with increased nocturnal gastroesophageal reflux (nocturnal GER) events and symptoms. Treatment of OSA with continuous positive airway pressure (CPAP) reduces nocturnal GER in patients with OSA. This study sought to determine the: (1) relationship of nocturnal GER events with apnea/hypopnea and arousal, (2) effect of upper airway obstruction on the barrier function of the lower esophageal sphincter (LES), (3) mechanism of LES failure for each nocturnal GER event and (4) effect of CPAP on LES function during sleep. METHODS Eight patients with OSA and nocturnal GER underwent polysomnography with esophageal manometry and pH monitoring. The first half of the night was spent without CPAP and the second half with 10 cmH(2)O CPAP. RESULTS Baseline LES barrier pressure (P (b)) was low in these patients. When patients were off CPAP, there were 2.7 ± 1.8 nocturnal GER events per hour and 70 ± 39 obstructive respiratory events per hour. There was no direct relationship between the occurrence of GER and obstructive events. While upper airway obstruction did not alter P (b), CPAP tended to increase the nadir P (b) during LES relaxation (LESR) and decreased the duration of LESR. CONCLUSIONS Upper airway obstructive and nocturnal GER events are not directly related. The relatively low P (b) in these OSA patients raises the possibility of weakening of the gastroesophageal junction from repetitive strain associated with obstructed breathing events. The favourable effect of CPAP on nocturnal GER is possibly due to an increase in nadir P (b) and decrease in the duration for which the LES relaxes during swallow-induced and transient LESR.

Abstract
Recent studies have demonstrated a bidirectional relationship between gastroesophageal reflux disease (GERD) and sleep where night-time reflux leads to sleep deprivation and sleep deprivation per se can exacerbate GERD by enhancing perception of intra-esophageal stimuli. Presently, treatment has primarily focused on reducing night-time reflux and thus improving sleep quality. Future studies are needed to further explore the relationship between GERD and sleep and the potential of novel therapeutic options to interrupt the vicious cycle between GERD and sleep.

Abstract
Gastroesophageal reflux disease (GERD) and sleep disturbances are both common health problems. There is a significant association between disturbed sleep and GERD, and this may be bidirectional. Sleep disorders may induce gastrointestinal (GI) disturbances, while GI symptoms also may provoke or worsen sleep derangements. Reflux of gastric acid is a less frequent event during sleep, however, acid clearance mechanisms (including swallowing, salivation and primary esophageal motility) are impaired during sleep resulting in prolongation of acid contact time. Nighttime reflux can lead to sleep disturbance and sleep disturbance may further aggravate GERD by prolonged acid contact time and heightened sensory perception. This may facilitate the occurrence of complicated GERD and decreased quality of life. However, the interplay between sleep problems and GERD is complex, and there are still relatively limited data on this issue. Further investigation of sleep-related GERD may identify common pathophysiological themes and new therapeutic targets.

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
Recent studies demonstrate a bidirectional relationship between gastroesophageal reflux disease (GERD) and sleep in which nighttime reflux leads to sleep deprivation and sleep deprivation can exacerbate GERD by enhancing perception of intraesophageal stimuli. Current treatment primarily focuses on reducing nighttime reflux, thus improving sleep quality. Future studies are needed to further explore the relationship between GERD and sleep and the potential of novel therapeutic options to interrupt the vicious cycle between them.

[PMID: 19111949 DOI: 10.1016/j.cgh.2008.11.021] [Citation(s) in RCA: 68] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/06/2008] [Revised: 10/27/2008] [Accepted: 11/19/2008] [Indexed: 01/26/2023]
Abstract
BACKGROUND & AIMS More than half of patients with chronic gastroesophageal reflux (GERD) report nocturnal symptoms. We performed systematic literature review to define nocturnal heartburn and to determine potential causality between nocturnal reflux and extraesophageal manifestations. METHODS We performed a search of literature published from 1974-2007. Each study was examined by 2 reviewers and rated on the basis of study type and outcome. RESULTS Screening of 445 trials identified 59 (13%) studies relevant for analysis. Twenty-two (5%) of the trials described potential changes in sleep parameters resulting from treatment of heartburn. In most studies, nocturnal reflux was defined as heartburn symptoms that impacted sleep quality and duration. On the basis of 5 large population studies, the mean +/- standard deviation prevalence of nocturnal heartburn was 54% +/- 22%. Consequences of nocturnal reflux included poor sleep quality, daytime fatigue, difficulty initiating sleep or arousals from sleep, and impaired work productivity. The strength of the association between the occurrence of nocturnal reflux and late evening meals was flawed as a result of the confounding effect of the evening meal content. There was no evidence supporting causality between nocturnal heartburn and asthma or obstructive sleep apnea. Subjective, but not objective, measures of sleep improved with antireflux therapy. Head of bed elevation, proton pump inhibitor therapy, H(2)-receptor antagonists, and Nissen fundoplication alleviated nocturnal heartburn and associated sleep disturbances. CONCLUSIONS Nocturnal GERD is common and is associated with adverse sleep parameters. It can be effectively managed with medical and surgical therapy.

Abstract
BACKGROUND We aimed to determine the prevalence of gastroesophageal reflux disease (GERD) and associated risk factors, and assess quality of life (QoL) in relation to the frequency and severity of reflux symptoms. METHODS A random sample of 1000 residents of Western Sydney were mailed a validated self-report questionnaire. GERD symptoms, risk factors, psychologic distress, QoL, and demographics were measured. RESULTS The response rate was 73% (n=672; mean age, 46 y; 52% female). A total of 78 [12%, 95% confidence interval (CI): 9-14] had GERD (at least weekly heartburn and/or acid regurgitation). Independent risk factors for GERD were high cholesterol [odds ratio (OR) =3.28, 95% CI: 1.42-7.57, P=0.005] and current smoker (OR=2.47, 95% CI: 1.07-5.70, P=0.03). Anxiety, depression, and neuroticism were not risk factors. Worse physical functioning was the only QoL domain associated with GERD (OR=0.98, 95% CI: 0.97-0.99, P=0.006). QoL was significantly impaired regardless of the severity of GERD for the QoL domains physical function, body pain, vitality, and social function. The frequency of heartburn and acid regurgitation were not associated with significantly reduced QoL domain scores. CONCLUSIONS Cardiac risk factors (high cholesterol and smoking) were independently associated with GERD. Increasing GERD symptom severity is associated with worse QoL scores, whereas GERD symptom frequency did not impact the QoL scores.

Abstract
Obesity has increased dramatically in the last 30 years, affecting 33% of the adult population in the United States. Increase in body mass index has been shown to be associated with the increase in the prevalence of gastroesophageal reflux disease (GERD) symptoms, esophageal mucosal injury, and GERD complications. The putative mechanisms responsible for the close relationship between GERD and increased body mass index include increased intragastric pressure, increased gastroesophageal pressure gradient, esophageal motor and sensory abnormalities, increase in prevalence of hiatal hernia, increase in serum female hormonal levels, diet, and increase in comorbidities. Whilst the current efforts are to focus on one major underlying mechanism, it is highly likely that multiple factors contribute to the increased prevalence of GERD in the obese patient.

Gastroesophageal reflux disease as an etiology of sleep disturbance in subjects with insomnia and minimal reflux symptoms: a pilot study of prevalence and response to therapy. Dig Dis Sci 2008; 53:1493-9. [PMID: 17985241 DOI: 10.1007/s10620-007-0057-1] [Citation(s) in RCA: 26] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/24/2007] [Accepted: 09/26/2007] [Indexed: 02/03/2023]
Abstract
BACKGROUND Gastroesophageal reflux disease (GERD) is a well-recognized cause of impaired sleep in patients with frequent GERD symptoms, as well as those with sleep apnea. GERD's role in sleep disturbance of minimally symptomatic patients with poor sleep quality is less clear. AIM We aimed to define the prevalence of GERD-related sleep disturbance in minimally-symptomatic subjects with demonstrated insomnia, and to assess the changes in sleep efficiency in these subjects after vigorous acid suppression. METHODS We recruited subjects aged 18-75 years reporting at least 6 months of insomnia, and sleep difficulty at least three nights per week. Subjects with a BMI > 30, a history of snoring or ongoing use of proton pump inhibitor or H2 receptor antagonist were excluded. Subjects underwent concurrent sleep study with dual channel 24-h pH study. Sleep efficiency, defined as the percentage of time after sleep initiation that the subject actually slept, and spontaneous arousal index, defined as the number of arousals per hour, were calculated. Those with a sleep study demonstrating poor sleep quality (sleep efficiency of < 83%, and > 10 arousals/h for those aged < 45, and > 15 for those who were 45 or older) and no obstructive sleep apnea were treated with rabeprazole 20 mg PO BID x 14 days. After 14 days, the subjects underwent repeat sleep study with pH monitoring. The GERD Symptom Assessment Scale (GSAS), the Epworth Sleepiness Scale (ESS) and the Functional Outcomes of Sleep Questionnaire (FOSQ) were administered to subjects at study inception and after 2 weeks of therapy. RESULTS Twenty-four subjects reporting insomnia were enrolled, and 20 met criteria for disordered sleep and no OSA. Seventeen completed both the first and second studies, and 16 were adequate for analysis. Baseline GSAS demonstrated trivial or no reflux symptoms in the cohort (no subject scored > 8 out of 45 on GSAS, corresponding to a median rating of reflux symptoms of "not at all"). Four of 16 subjects (25%) demonstrated abnormal pH studies at baseline. All four had normalization of acid exposures on PPI. After 2 weeks of treatment, three of these four subjects had normalization of sleep efficiency, compared to 4 of 12 of the subjects with normal Johnson-DeMeester scores. Repeated measures analysis showed significant improvement in spontaneous arousal index between the first and second study for the whole group (P < 0.0035). Pre- and post-therapy ESS and FOSQ scores were not significantly different. CONCLUSIONS Despite the lack of GERD symptoms, a significant minority of subjects with sleep disturbance have abnormal acid exposures. These preliminary data suggest that aggressive treatment of GERD in such patients may result in improvement in sleep efficiency.

Abstract
BACKGROUND Obesity is a risk factor for gastroesophageal reflux disease (GERD) and for obstructive sleep apnea (OSA). Our aim was to evaluate in morbidly obese patients the prevalence of OSA and GERD and their possible relationship. METHODS Morbidly obese patients [body mass index (BMI) >40 or >35 kg/m(2) in association with comorbidities] selected for bariatric surgery were prospectively included. Every patient underwent a 24-h pH monitoring, esophageal manometry, and nocturnal polysomnographic recording. RESULTS Sixty-eight patients [59 women and 9 men, age 39.1 +/- 11.1 years; BMI 46.5 +/- 6.4 kg/m(2) (mean +/- SD)] were included. Fifty-six percent of patients had an abnormal Demester score, 44% had abnormal time spent at pH <4, and 80.9% had OSA [apnea hypopnea index (AHI) >10] and 39.7% had both conditions. The lower esophageal sphincter (LES) pressure was lower in patients with GERD (11.6 +/- 3.4 vs 13.4 +/- 3.6 mm Hg, respectively; P = 0.039). There was a relationship between AHI and BMI (r = 0.337; P = 0.005). Patients with OSA were older (40.5 +/- 10.9 vs 33.5 +/- 10.4 years; P = 0.039). GERD tended to be more frequent in patients with OSA (49.1% vs 23.1%, respectively; P = 0.089). There was no significant relationship between pH-metric data and AHI in either the 24-h total recording time or the nocturnal recording time. In multivariate analysis, GERD was significantly associated with a low LES pressure (P = 0.031) and with OSA (P = 0.045) but not with gender, age, and BMI. CONCLUSION In this population of morbidly obese patients, OSA and GERD were frequent, associated in about 40% of patients. GERD was significantly associated with LES hypotonia and OSA independently of BMI.

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
BACKGROUND AND AIMS Since the publication of the Asia-Pacific GERD consensus in 2004, more data concerning the epidemiology and management of gastroesophageal reflux disease (GERD) have emerged. An evidence based review and update was needed. METHODS A multidisciplinary group developed consensus statements using the Delphi approach. Relevant data were presented, and the quality of evidence, strength of recommendation, and level of consensus were graded. RESULTS GERD is increasing in frequency in Asia. Risk factors include older age, male sex, race, family history, higher socioeconomic status, increased body mass index, and smoking. Symptomatic response to a proton pump inhibitor (PPI) test is diagnostic in patients with typical symptoms if alarm symptoms are absent. A negative pH study off therapy excludes GERD if a PPI test fails. The role for narrow band imaging, capsule endoscopy, and wireless pH monitoring has not yet been undefined. Diagnostic strategies in Asia must consider coexistent gastric cancer and peptic ulcer. Weight loss and elevation of head of bed improve reflux symptoms. PPIs are the most effective medical treatment. On-demand therapy is appropriate for nonerosive reflux disease (NERD) patients. Patients with chronic cough, laryngitis, and typical GERD symptoms should be offered twice daily PPI therapy after excluding non-GERD etiologies. Fundoplication could be offered to GERD patients when an experienced surgeon is available. Endoscopic treatment of GERD should not be offered outside clinical trials. CONCLUSIONS Further studies are needed to clarify the role of newer diagnostic modalities and endoscopic therapy. Diagnostic strategies for GERD in Asia must consider coexistent gastric cancer and peptic ulcer. PPIs remain the cornerstone of therapy.

Abstract
Patients with obstructive sleep apnea are at risk of mortality and morbidity related to the administration of sedatives, anesthetics, and opioids. Commonly employed sedatives and analgesics promote pharyngeal collapse and alter normal respiratory responses to obstruction and apnea. Literature concerning patients with obstructive sleep apnea undergoing moderate and deep sedation in the endoscopy suite is lacking. The purpose of this article is to provide the reader with a review of normal airway patency, the effects of obstructive sleep apnea on airway patency, and the impact that analgesics and sedatives may impart on the airway of patients with obstructive sleep apnea. The goal of this article is to increase awareness, stimulate discussions within the gastroenterological community, and encourage research regarding sedation in this at-risk population.
