The effect of antireflux treatment on the frequency of awakenings from sleep in patients with Gastroesophageal reflux disease

Wake up to gastro-oesophageal reflux disease: The interplay between arousal and night-time reflux

This review examines the temporal association between nocturnal gastro-oesophageal reflux and sleep-arousal cycles. Most nocturnal gastro-oesophageal reflux events occur during the awake cycle, and arousals precede most nocturnal gastro-oesophageal reflux events, indicating that arousal from sleep predisposes to nocturnal gastro-oesophageal reflux. This sheds light on the complex relationship between nocturnal gastro-oesophageal reflux and sleep, and has implications for managing nocturnal gastro-oesophageal reflux symptoms. The appearance of symptoms and the pathophysiology of nocturnal gastro-oesophageal reflux are influenced by sleep hygiene, sleep disturbances and the misalignment of circadian rhythms. Nocturnal gastro-oesophageal reflux and its related sleep disorders are prevalent and negatively impact the quality of life. There is conflicting evidence on whether nocturnal gastro-oesophageal reflux and sleep disturbances are causally linked, and whether sleep disturbances drive nocturnal gastro-oesophageal reflux. Poor sleep quality increases oesophageal hypersensitivity and overall acid exposure. The nocturnal gastro-oesophageal reflux is linked to the more severe forms of gastro-oesophageal reflux disease, especially with atypical/extra-oesophageal manifestations and complications of mucosal damage such as oesophagitis and stricture, Barret's oesophagus, and oesophageal adenocarcinoma. This review highlights the role of sleep problems in presenting nocturnal gastro-oesophageal reflux, and the potential benefits of treating sleep disturbances in enhancing patient care and quality of life.

Relationship between gastroesophageal reflux disease and objective sleep quality

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.

Reduced gastroesophageal reflux disease symptom severity following upper airway surgery for comorbid obstructive sleep apnea

PURPOSE

To evaluate patient-reported quality of life pertaining to gastroesophageal reflux disease symptoms in patients undergoing upper airway surgery for comorbid obstructive sleep apnea.

MATERIALS AND METHODS

A prospective survey-based study was conducted on patients with gastroesophageal reflux disease and comorbid obstructive sleep apnea receiving surgery from July 2020-December 2020. Patients completed the Gastroesophageal Reflux Disease-Health Related Quality of Life Questionnaire at two time-points: one week before surgery and at 6 months following surgery. Disease-related symptoms were rated from 0 (no symptoms) to 5 (incapacitating symptoms). Patient survey scores, demographics, medications, and sleep study parameters were collected for analysis. A p-value <0.05 indicated statistical significance.

RESULTS

Twenty-two patients completed the baseline preoperative and 6-month postoperative questionnaires. Median baseline vs. 6-month survey scores significantly decreased for symptoms including heartburn in general (3.0 vs. 2.0, p = 0.006), when lying down (2.5 vs. 1.5, p = 0.046), when standing (2.0 vs 1.0, p = 0.003), following meals (2.0 vs. 2.0, p = 0.042), and cumulative survey score (15.5 vs. 11.0, p = 0.029). Heartburn altering diet or sleep, odynophagia, dysphagia, and medication burden did not change following surgery (p > 0.05). More patients were satisfied with their postoperative condition compared to baseline, however this did not reach statistical significance (40.9% vs. 18.2%, p = 0.18).

CONCLUSIONS

Our results suggest that upper airway surgery to treat obstructive sleep apnea may have a positive impact on patient-reported symptoms of gastroesophageal reflux disease, and further investigation into the role of surgery in this setting for improvement of both quality of life and true clinical disease severity is merited.

The association between laryngopharyngeal reflux and insomnia

OBJECTIVES

To evaluate the prevalence of insomnia in patients with laryngopharyngeal reflux (LPR) and to analyze the relationship between the severity of insomnia and LPR-related symptoms.

METHODS

We analyzed 69 patients with LPR and 61 healthy controls. The LPR was confirmed via the 24-h hypopharyngeal-esophageal multichannel intraluminal impedance pH monitoring. Reflux symptoms and sleep disturbances were assessed using the Reflux Symptom Index and Insomnia Severity Index. We compared the prevalence of insomnia between the two groups. We analyzed the relationship between reflux symptoms and severity of insomnia.

RESULTS

The prevalence of insomnia was significantly higher in patients with LPR than in healthy controls (46.3% vs. 29.5%; p = 0.049). The severity of reflux-related symptoms was correlated with insomnia severity (rho = 0.44; p < 0.001). Patients with LPR with nighttime reflux were more likely to have sleep disturbances than patients with LPR without nighttime reflux.

CONCLUSION

Patients with LPR are more likely to experience insomnia than healthy controls, and the severity of reflux symptoms was related to the severity of insomnia.

The evaluation of recumbent reflux by multichannel intraluminal impedance pH testing for patients with gastroesophageal reflux disease and sleep disturbance

BACKGROUND AND AIM

The relationship between gastroesophageal reflux disease (GERD) and sleep disturbance has recently been pointed out and is garnering substantial attention. Although there are reports that point out the effectiveness of medical treatment for sleep disturbance associated with GERD, examinations of the pathological condition, including reflux during sleep, are inadequate. In the present study, we evaluated the recumbent reflux in patients with GERD and sleep disturbance using multichannel intraluminal impedance pH (MII-pH), and attempted to suppress recumbent reflux by surgical treatment to examine the pathophysiology of patients with GERD and sleep disturbance.

MATERIALS AND METHODS

Of the 47 patients with GERD-related diseases in whom laparoscopic fundoplication was performed at The Jikei University Hospital from January 2016 to June 2017, 31 patients (average age: 55.9 ± 13.8 years, male in 25), excluding 9 with surgical indications only for esophageal hiatal hernia and 7 without postoperative evaluation, were the subjects of this study. All surgical procedures were performed by the Toupet method. We used the Pittsburgh Sleep Quality Index (PSQI) to evaluate sleep disturbance, setting 5.5 as the cut-off value, based on the report by Doi et al., with any conditions beyond this value deemed sleep disturbance. The evaluation of gastroesophageal reflux was carried based on the MII-pH using the Sleuth, manufactured by Sandhill Corporation, with an automatic analysis carried out by computer. Furthermore, recumbent abnormal reflux was defined as recumbent all reflux (times) > 7. All evaluations were performed preoperatively and at 3 months after the operation. The data were expressed in medians and interquartile ranges, with p < 0.05 defined as statistically significant by the Mann-Whitney, Wilcoxon, or Chi-squared test.

RESULTS

Although sleep disturbance was found in 19 cases (61%), 8 (42%) of which were actually confirmed as nighttime abnormal reflux, of whom 5 cases (63%) showed significant improvement in their sleep disturbance following the operation, with a PSQI score of lower than 5.5. Among these 5 cases, postoperative recumbent abnormal reflux was also significantly reduced as compared with the preoperative condition (17 vs. 2 times/day, p = 0.042). Furthermore, sleep disturbance improved and recumbent abnormal reflux also decreased in two cases, with sleep disturbance improved by controlling the nighttime reflux via surgery in a total of 7 cases (87.5%). Although the PSQI score was as high as 14 points before and after the operation in one case, the rate of recumbent abnormal reflux was remarkably reduced, with sleep disturbance and recumbent reflux considered irrelevant. Furthermore, regarding the frequency of recumbent acid/non-acid reflux, while non-acid reflux was significantly more frequent in the patients with recumbent reflux complications (9 vs. 1 time/day, p < 0.001), there was no marked difference in the frequency of acid reflux.

CONCLUSIONS

Among cases with GERD and sleep disturbance, approximately one-third of them showed findings suggestive of the involvement of recumbent reflux in sleep disturbance, with reflux characterized by non-acid reflux.

Temporal Relationship Between Night-Time Gastroesophageal Reflux Events and Arousals From Sleep

INTRODUCTION

Night-time gastroesophageal reflux (nGER) symptoms are commonly associated with interrupted sleep. Most studies attempting to understand the relationship between sleep, arousal, and nGER events have been performed so using accelerometry; however, this technology is limited in its ability to precisely determine the temporal association between sleep and reflux events. We aimed to examine the temporal relationships between nGER events and arousal/awakening from sleep using high resolution, in-laboratory polysomnography (PSG).

METHODS

Individuals between 18 and 70 years who had undergone a gastroscopy within 12 months underwent simultaneous 24-hour pH/impedance monitoring and in-laboratory PSG. The temporal relationship between each nGER event and sleep/arousals/awakenings was determined for each participant. Analyses were limited to the sleep period (between "lights out" and time of final waking).

RESULTS

Analyses were conducted on the data from 25 individuals, 64% of whom had nGER episodes (5 ± 5 events per person, range 1-18) and 64% of whom had obstructive sleep apnea (OSA, mean apnea-hypopnea index 20 ± 11 events/hr, range 6-44). There were no differences in PSG-determined sleep duration, sleep efficiency, sleep architecture, arousals/awakenings, or sleep apnea severity between those with nGER and those without. Most nGER events (82%) occurred during a PSG epoch that had been classified as wake. Arousals/awakenings preceded almost all events (73/76), whereas fewer had an arousal/awakening after the event (15/76).

DISCUSSION

As opposed to what is typically assumed, nGER does not seem to cause arousal from sleep, but rather arousal from sleep predisposes to nGER.

Randomised clinical trial: vonoprazan versus lansoprazole for the initial relief of heartburn in patients with erosive oesophagitis

BACKGROUND

Proton pump inhibitors (PPIs) are widely used to treat gastro-oesophageal reflux disease (GORD). However, the onset of action is considered slow and PPIs cannot completely block acid secretion at night. A new potassium-competitive acid blocker (P-CAB) can rapidly block acid secretion. However, whether this P-CAB can relieve GORD symptoms quickly and adequately soon after starting treatment is unknown.

AIM

To determine how rapidly vonoprazan and lansoprazole provide heartburn relief.

METHODS

Patients (n = 32) with endoscopically confirmed erosive oesophagitis who experienced heartburn at least once a week were randomised in a double-blind manner to receive either daily vonoprazan (20 mg) or lansoprazole (30 mg) before breakfast for 14 days. Day time and night time heartburn were assessed daily throughout the study using a five-point Likert scale. The primary endpoint was the first day of complete day and night heartburn relief for at least seven consecutive days. The ethics committees of the participating institutions approved the study protocol.

RESULTS

Heartburn was relieved sooner with vonoprazan than with lansoprazole (P < 0.05, log-rank test). Heartburn was completely relieved in 31.3% and 12.5% of patients on day 1 with vonoprazan and lansoprazole, respectively. Significantly more patients achieved complete nocturnal heartburn relief with vonoprazan than lansoprazole (P < 0.01). Both regimens were well tolerated.

CONCLUSIONS

Complete sustained heartburn relief was achieved sooner with vonoprazan than with lansoprazole during the first week of therapy. (UMIN000018776).

Gastroesophageal reflux disease and its related factors among women of reproductive age: Korea Nurses' Health Study

Background

Recently, the number of patients diagnosed with gastroesophageal reflux disease (GERD) has increased in Korea. Risk factors of GERD include age, sex, medication use, lack of physical exercise, increased psychological stress, low or high body mass index (BMI), unhealthy eating habits, increased alcohol consumption, and cigarette smoking. However, few studies examined the major factors affecting GERD in women of childbearing age. Therefore, this study assessed the risk factors of GERD among 20,613 female nurses of reproductive age using data from the Korea Nurses’ Health Study.

Methods

Participants were recruited from July 2013 to November 2014. They provided their history of GERD 1 year prior to data collection, along with information on their demographic characteristics, health-related behaviors, diet, medical history, and physical and psychological factors. Of the total sample, 1184 individuals with GERD diagnosed in the year prior to the study were identified. Propensity score matching was used for analysis.

Results

Cigarette smoking, increased alcohol consumption, low or high BMI, depression, and increased psychosocial stress were associated with the prevalence of GERD among Korean young women. Multivariate ordinal logistic regression analysis revealed significant positive relationships between GERD and being a former smoker; having a low (< 18.5 kg/m²) or high BMI (> 23 kg/m²); and having mild, moderate, moderately severe, and severe depression.

Conclusions

Smoking, BMI, and depression were associated with GERD. To reduce this risk among female nurses, intervention strategies are required to help nurses maintain a normal weight and manage their depression.

Sleep and Nocturnal Gastroesophageal Reflux: An Update

Nocturnal gastroesophageal reflux has been associated with poor sleep quality. Normal physiological adaptations of the aerodigestive system to sleep prolong and intensify nocturnal reflux events. This occurrence leads to sleep disruption, as well as to esophageal, laryngeal, and laryngopharyngeal reflux. Controversy exists on whether OSA and nocturnal reflux are causally linked or merely associated because of shared risk factors. Advances in diagnostic technology have provided new insights into gastroesophageal reflux and the mechanisms of nocturnal reflux during sleep. This update reviews new data on causal links between sleep and gastroesophageal reflux disease.

A nonpharmacologic approach to managing insomnia in primary care

Insomnia, or inadequate or poor sleep leading to significant distress or impairment in functioning, is a prevalent disorder treated by primary care providers (PCPs). With millions of people across the United States suffering from insomnia, PCPs must understand the disorder's pathophysiology, perpetuating factors, and treatment, as well as its effect on patient health and the economy. Although PCPs traditionally treat insomnia with pharmaceuticals, behavioral measures are effective and should be used whenever possible. This article reviews clinically relevant principles of diagnosing and treating insomnia, highlighting nonpharmacologic treatments.
