Abstract
Gastroesophageal reflux disease (GERD) is associated with sleep disturbances. However, mechanisms underlying these interactions remain unclear. Male acute and chronic sleep deprivation (SD) mice were used for this study. Mice in the chronic SD group exhibited anxiety- and depression-like behaviors. We further performed high-throughput genome sequencing and bioinformatics analysis to screen for featured differentially expressed genes (DEGs) in the esophageal tissue. The acute SD group, comprised 25 DEGs including 14 downregulated and 11 upregulated genes. Compared with the acute SD group, more DEGs were present in the chronic SD group, with a total of 169 DEGs, including 88 downregulated and 81 upregulated genes. Some DEGs that were closely related to GERD and associated esophageal diseases were significantly different in the chronic SD group. Quantitative real-time polymerase chain reaction verified the downregulation of Krt4, Krt13, Krt15 and Calml3 and upregulation of Baxl1 and Per3. Notably, these DEGs are involved in biological processes, which might be the pathways of the neuroregulatory mechanisms of DEGs expression.

Abstract
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.

Abstract
Background The main components of gastroesophageal reflux disease (GERD) management include a combination of medications and lifestyle modifications; Nevertheless, based on the severity of symptoms and their response to medications, other treatments could be considered. Baclofen has been demonstrated in studies to relieve GERD symptoms. The current study aimed to precisely address the effects of baclofen on the treatment of GERD and its characteristics. Methods A systematic search was carried out in Pubmed/Medline, Cochrane CENTRAL, Scopus, Google Scholar, Web of Science, and clinicaltrials.gov up to December 10, 2021. The search terms included baclofen, GABA agonists, GERD, and reflux. Results We selected 26 papers that matched the inclusion criteria after examining 727 records. Studies were classified into four categories based on the study population and reported outcomes: (1) adults, (2) children, (3) patients with gastroesophageal reflux-induced chronic cough, (4) hiatal hernia patients. The results revealed that baclofen can significantly improve reflux symptoms and pH-monitoring and manometry findings to different degrees in all four mentioned categories; although its effect on pH-monitoring parameters seems less significant than the other parameters. Mild neurological and mental status deterioration were the most reported side effects. However, side effects occurred in a portion of less than 5% of short-term users and nearly 20% of long-term users. Conclusion In PPI-resistant patients, a trial of adding baclofen to the PPI may be helpful. Baclofen therapies may be more beneficial for symptomatic GERD patients who also report concurrent conditions including alcohol use disorder, non-acid reflux, or obesity.

Abstract
BACKGROUND Nocturnal gastroesophageal reflux symptoms have a major impact on sleep quality and are associated with complicated gastroesophageal reflux disease (GERD). We performed a systematic review to assess the data on the effectiveness of the currently available interventions for the treatment of nocturnal reflux symptoms. METHODS We searched PubMed, EMBASE, and the Cochrane Library. All prospective, controlled, and uncontrolled clinical trials in adult patients describing interventions (lifestyle modifications, surgical and pharmacological) for nocturnal gastroesophageal reflux symptoms were assessed for eligibility. A narrative descriptive summary of findings is presented together with summary tables for study characteristics and quality assessment. KEY RESULTS The initial reference search yielded 3067 citations; 66 citations were screened in full text, of which 31 articles were included. Studies on lifestyle modifications include head of bed elevation (n = 5), prolonging dinner-to-bed time (n = 2), and promoting left lateral decubitus position (n = 2). Placebo-controlled clinical trials investigating proton pump inhibitors (PPIs) (n = 11) show success rates ranging from 34.4% to 80.8% in the PPI group versus 10.4%-51.7% in the placebo group. Laparoscopic fundoplication is reserved for severe disease only. There is insufficient evidence for a recommendation on the use of nasal continuous positive airway pressure (nCPAP), hypnotics, baclofen and adding bedtime H2 receptor antagonists for reducing nocturnal reflux. CONCLUSION INFERENCES: A sequential treatment strategy, including head of bed elevation, prolonging dinner-to-bed time, promoting left lateral decubitus position and treatment with acid-suppressive medication is recommended for nocturnal gastroesophageal reflux symptoms. Currently, there is insufficient evidence for the use of nCPAP, hypnotics, baclofen and adding bedtime H2 receptor antagonists.

Trials 2022; 23:880.

Abstract
Background Treatment of opiate addiction with opiate substitution treatment (e.g. methadone) is beneficial. However, some individuals desire or would benefit from abstinence but there are limited options to attenuate problems with opiate withdrawal. Preclinical and preliminary clinical evidence suggests that the GABA-B agonist, baclofen, has the desired properties to facilitate opiate detoxification and prevent relapse. This study aims to understand whether there are any safety issues in administering baclofen to opioid-dependent individuals receiving methadone. Methods Opiate-dependent individuals (DSM-5 severe opioid use disorder) maintained on methadone will be recruited from addiction services in northwest London (NHS and third sector providers). Participants will be medically healthy with no severe chronic obstructive pulmonary disease or type 2 respiratory failure, no current dependence on other substances (excluding nicotine), no current severe DSM-5 psychiatric disorders, and no contraindications for baclofen or 4800 IU vitamin D (placebo). Eligible participants will be randomised in a 3:1 ratio to receive baclofen or placebo in an adaptive, single-blind, ascending dose design. A Bayesian dose-escalation model will inform the baclofen dose (10, 30, 60, or 90 mg) based on the incidence of ‘dose-limiting toxicity’ (DLT) events and participant-specific methadone dose. A range of respiratory, cardiovascular, and sedative measures including the National Early Warning Score (NEWS2) and Glasgow Coma Scale will determine DLT. On the experimental day, participants will consume their usual daily dose of methadone followed by an acute dose of baclofen or placebo (vitamin D3) ~ 1 h later. Measures including oxygen saturation, transcutaneous CO2, respiratory rate, QTc interval, subjective effects (sedation, drug liking, craving), plasma levels (baclofen, methadone), and adverse events will be obtained using validated questionnaires and examinations periodically for 5 h after dosing. Discussion Study outcomes will determine what dose of baclofen is safe to prescribe to those receiving methadone, to inform a subsequent proof-of-concept trial of the efficacy baclofen to facilitate opiate detoxification. To proceed, the minimum acceptable dose is 30 mg of baclofen in patients receiving ≤ 60 mg/day methadone based on the clinical experience of baclofen’s use in alcoholism and guidelines for the management of opiate dependence.

Abstract
PURPOSE OF REVIEW Gastroesophageal reflux disease is one of the most common conditions encountered by primary care physicians, gastroenterologists, foregut surgeons and otolaryngologists. While approximately 50% of patients experience nocturnal reflux symptoms, the relationship between gastroesophageal reflux disease and sleep is often overlooked. The aim of this review is to provide an update on the current understanding of this relationship and its clinical implications. Recent studies pertaining to the association between GERD and sleep with focus on sleep disturbances, obstructive sleep apnea, extraesophageal manifestations of GERD and treatment are discussed. RECENT FINDINGS There is a close relationship between GERD and sleep disturbances, but the nature of this relationship remains to be elucidated. Similarly, new data supports the association between GERD and obstructive sleep apnea, but whether this association is independent of confounding risk factors remains unresolved. Extraesophageal manifestations due to nocturnal GERD are primarily respiratory and can be explained by microaspiration and vagally-induced bronchospasm. Treatment of nocturnal GERD, both pharmacologically and surgically, improves sleep quality. Conversely, pharmacologic treatment of sleep disorders can improve nocturnal GERD symptoms. There is a bi-directional relationship between GERD and sleep. GERD is associated with various sleep disturbances. Sleep deficiency can exacerbate GERD. There is an association between extraesophageal manifestations and nocturnal GERD. Treatment directed towards GERD can improve sleep experience, and treatment directed to improve sleep can improve GERD symptoms.

Multitargeting the sleep-pain interaction with pharmacological approaches: A narrative review with suggestions on new avenues of investigation. Sleep Med Rev 2021; 59:101459.

Abstract
The multimorbidity formed by sleep disturbances and pain conditions is highly prevalent and has a significant impact in global health and in the socioeconomic system. Although different approaches have been directed toward its management, evidence regarding an optimal treatment is lacking, and pharmacological options are often preferred. Health professionals (e.g., pain and sleep clinicians) tend to focus on their respective expertise, targeting a single symptom with a single drug. This may increase polypharmacy and the risk of drug interactions, adverse events, and mortality. Hence, the use of medications that can directly or indirectly improve sleep, pain, and other possible accompanying conditions without exacerbating them becomes especially relevant. The objectives of this comprehensive review are to: a) describe the beneficial or deleterious effects that some commonly used medications to manage pain have on sleep and sleep disorders; and b) describe the beneficial or deleterious effects that frequently prescribed medications for sleep may have on pain. Moreover, medications targeting some specific sleep-pain interactions will be suggested and future directions for improving sleep and alleviating pain of these patients will be provided with clinical and research perspectives.

Abstract
Gastroesophageal reflux disease (GERD) is a prevalent, chronic medical condition that affects 13% of the adult population globally at least once a week. Sleep disturbances are frequently encountered in up to 25% of the GERD patients, likely due to nocturnal gastroesophageal reflux (GER). With advance in diagnostic techniques allowing for an improved understanding of involved physiological mechanisms of nocturnal reflux, there is growing evidence of a bidirectional relationship between GERD and sleep disturbances. Furthermore, nocturnal GER is associated with more complicated GERD. Obstructive sleep apnea (OSA) and GERD also have been linked, but to what degree remains controversial. Treatment of nocturnal GER has been shown to improve both subjective and objective sleep measures. The therapeutic approach includes lifestyle modifications and medication individualization and optimization with proton-pump inhibitors serving as the mainstay of treatment. Antireflux surgery and newer endoscopic procedures have been demonstrated to control nocturnal GER.

Abstract
STUDY OBJECTIVES Insomnia is a common medical complaint. Current pharmacologic treatments have modest efficacy and numerous side effects. Baclofen is a gamma-aminobutyric acid (GABA)b receptor agonist used to treat spasticity in various medical conditions. Several studies noted that baclofen, when used to treat sleep related disorders, resulted in improvement in sleep parameters. Measures of insomnia, however, were not assessed in those studies. To date, baclofen has not been assessed for efficacy in the treatment of insomnia. METHODS We randomized 20 healthy subjects to baclofen or placebo in a cross over design. All subjects underwent two polysomnograms (PSG) assessing sleep parameters. Baclofen or placebo was given 90 min prior to lights out in random order for each subject. Lights out occurred two hours earlier than the subject's median habitual bedtime. RESULTS Baclofen resulted in significantly less objective wake after sleep onset and stage 1 sleep, and significantly increased total sleep time (TST), sleep efficiency, and stage 3/4 sleep. There was no effect on sleep onset latency (SOL). Self-report variables indicated significantly less subjective awakenings from sleep and increased subjective sleep quality. There was no effect on subjective TST or subjective SOL. CONCLUSIONS This study showed that baclofen was superior to placebo with regard to several objective and subjective measures used to assess sleep quality. These data support the notion that baclofen shows promise as an effective hypnotic drug.

Abstract
BACKGROUND The clinical impact of head-of-bed elevation in patients with gastro-oesophageal reflux disease is unclear, because of inconsistency and methodological limitations of previous studies. PATIENTS AND METHODS A randomised single-blind single-centre controlled clinical trial with a 2x2 cross-over design, in 39 pharmacologically treated patients with gastro-oesophageal reflux disease. Active intervention was to use a head-of-bed-elevation of 20cm for 6 weeks and then to sleep without inclination for 6 additional weeks, with a wash-out of 2 weeks between periods. The primary outcome was a change ≥10% in RDQ score and secondary outcomes were a change ≥10% in SF-36 score, patient preference and frequency of adverse events. RESULTS 27 (69.2%) patients who used the intervention reached the primary outcome vs 13 (33.3%) patients in the control group (RR: 2.08; 95 CI%: 1.19 - 3.61). No effect was found in SF-36 score (RR: 1.11; 95% CI: 0.47 - 2.60). Preference favouring the intervention was 77.1% and adverse event proportion was 54.0%. CONCLUSION Head-of-bed elevation improved reflux symptoms but there was no effect on quality of life. The finding of a non-optimal risk-benefit ratio warrants additional studies before this intervention can be recommended (IBELGA, ClinicalTrials.gov identifier NCT02706938).

Abstract
Systemic scleroderma/sclerosis (SSc) is an autoimmune connective tissue disease, which can lead to esophageal motor dysfunction and gastroesophageal reflux disease (GERD). Nocturnal GERD symptoms may be associated with sleep disturbances, which in turn can drastically affect well-being and fatigue levels. We hypothesized that GERD symptoms would be associated with poorer sleep in patients with SSc. Rheumatologist established SSc patients completed the following questionnaires: the UCLA scleroderma clinical trial consortium gastrointestinal tract instrument (GIT) 2.0 questionnaire; the Pittsburgh sleep quality index (PSQI); the fatigue severity scale (FSS); the multidimensional gastrointestinal symptom severity index (GSSI). Poor sleep quality was defined by a PSQI total score >5. Questionnaires were completed by 287 patients [mean (SD) age = 59 (14) years; female = 243]. Poor sleep quality was identified in 194 (68%) patients. Patients with poor sleep quality reported less sleep time and increased fatigue compared to those with normal sleep scores. SSc patients with poor sleep had significantly higher GIT Reflux scores (P < .001), and poor sleep was more frequent in those with moderate/severe versus mild/no heartburn on GISSI (P < .001). Narcotic and antidepressant use was significantly more frequent in SSc patients with poor sleep quality. Multivariable logistic regression supported the association between GERD symptoms and poor sleep after controlling for age, sex, and body mass index (BMI) (2.53, 95% confidence interval (CI) 1.52-4.25; P < .001). The association remained after controlling for narcotic and antidepressant use (2.20, 95% CI 1.29-3.73; P < .001). SSc patients who reported GERD symptoms were also more likely to report poor sleep quality. Future studies should examine mechanisms underlying nocturnal GERD symptoms in SSc patients, and the impact of improved GERD symptom control on sleep quality.

Abstract
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.

Abstract
Cannabidiol (CBD) is a component of Cannabis sativa that has a broad spectrum of potential therapeutic effects in neuropsychiatric and other disorders. However, few studies have investigated the possible interference of CBD on the sleep-wake cycle. The aim of the present study was to evaluate the effect of a clinically anxiolytic dose of CBD on the sleep-wake cycle of healthy subjects in a crossover, double-blind design. Twenty-seven healthy volunteers that fulfilled the eligibility criteria were selected and allocated to receive either CBD (300 mg) or placebo in the first night in a double-blind randomized design (one volunteer withdrew from the study). In the second night, the same procedure was performed using the substance that had not been administered in the previous occasion. CBD or placebo were administered 30 min before the start of polysomnography recordings that lasted 8 h. Cognitive and subjective measures were performed immediately after polysomnography to assess possible residual effects of CBD. The drug did not induce any significant effect (p > 0.05). Different from anxiolytic and antidepressant drugs such as benzodiazepines and selective serotonin reuptake inhibitors, acute administration of an anxiolytic dose of CBD does not seem to interfere with the sleep cycle of healthy volunteers. The present findings support the proposal that CBD do not alter normal sleep architecture. Future studies should address the effects of CBD on the sleep-wake cycle of patient populations as well as in clinical trials with larger samples and chronic use of different doses of CBD. Such studies are desirable and opportune.

Abstract
A significant percentage of patients with gastroesophageal reflux disease (GERD) will not respond to proton pump inhibitor (PPI) therapy. The causes of PPI-refractory GERD are numerous and diverse, and include adherence, persistent acid, functional disorders, nonacid reflux, and PPI bioavailability. The evaluation should start with a symptom assessment and may progress to imaging, endoscopy, and monitoring of esophageal pH, impedance, and bilirubin. There are a variety of pharmacologic and procedural interventions that should be selected based on the underlying mechanism of PPI failure. Pharmacologic treatments can include antacids, prokinetics, alginates, bile acid binders, reflux inhibitors, and antidepressants. Procedural options include laparoscopic fundoplication and LINX as well as endoscopic procedures, such as transoral incisionless fundoplication and Stretta. Several alternative and complementary treatments of possible benefit also exist.

Abstract
Alcohol use disorder (AUD) is a brain disorder associated with high rates of mortality and morbidity worldwide. Baclofen, a selective gamma-aminobutyric acid-B (GABA-B) receptor agonist, has emerged as a promising drug for AUD. The use of this drug remains controversial, in part due to uncertainty regarding dosing and efficacy, alongside concerns about safety. To date there have been 15 randomized controlled trials (RCTs) investigating the use of baclofen in AUD; three using doses over 100 mg/day. Two additional RCTs have been completed but have not yet been published. Most trials used fixed dosing of 30-80 mg/day. The other approach involved titration until the desired clinical effect was achieved, or unwanted effects emerged. The maintenance dose varies widely from 30 to more than 300 mg/day. Baclofen may be particularly advantageous in those with liver disease, due to its limited hepatic metabolism and safe profile in this population. Patients should be informed that the use of baclofen for AUD is as an "off-label" prescription, that no optimal fixed dose has been established, and that existing clinical evidence on efficacy is inconsistent. Baclofen therapy requires careful medical monitoring due to safety considerations, particularly at higher doses and in those with comorbid physical and/or psychiatric conditions. Baclofen is mostly used in some European countries and Australia, and in particular, for patients who have not benefitted from the currently used and approved medications for AUD.

Abstract
OBJECTIVE GERD is among the most common outpatient disease processes encountered by clinicians on a daily basis. This review provides insights about how to approach GERD in terms of disease management and treatment. METHODS Review articles were searched using PUBMED and MEDLINE using criteria that included English language articles published in the last 5 years concerning studies carried out only in humans. The key words used in the searches were GERD, PPI, and erosive esophagitis. Recommendations from the American College of Gastroenterology are also included in this manuscript. RESULTS The search resulted in ∼260 articles. The manuscript brings together and presents the results of recent recommendations from professional societies and recently published review articles on GERD. CONCLUSION GERD is one of the most common diagnoses made by gastroenterologists and primary care physicians. It is important to recognize the typical and atypical presentations of GERD. This paper helps primary care physicians understand the disease's pathophysiology, and when, how, and with what to treat GERD before referring patients to gastroenterologists or surgeons.

Abstract
BACKGROUND AND AIMS Muscle cramps adversely influence the quality of life of patients with liver cirrhosis. Indeed, to date, a well-established therapy for this complication is still lacking. This is the first randomized placebo-controlled trial of baclofen in the treatment of muscle cramps in patients with liver cirrhosis. PATIENTS AND METHODS A total of 100 patients with liver cirrhosis and muscle cramps signed an informed consent to participate in this study. They were recruited from the Department of Tropical Medicine-Tanta University Hospital. They were randomized to receive either baclofen or placebo for 3 months. Patients were followed monthly and 1 month after withdrawal. At each visit, the clinicoepidemiological data were recorded, the muscle cramp questionnaire was filled, and any drug-related side effects were reported. RESULTS In the baclofen group, the frequency of muscle cramps decreased significantly after 1 and 3 months of treatment (P<0.005), with a significant relapse after withdrawal (P<0.001). Patients receiving baclofen showed a significant decrease in the severity and duration of muscle cramps (P<0.001). After 3 months of baclofen therapy at a dose of 30 mg/day, muscle cramps disappeared completely in 72%, reduced in 20%, and led to no change in 8% of patients. No significant changes in the frequency, severity, and duration of muscle cramps were noted in the placebo group. There were few but nonsignificant side effects in the baclofen group compared with the placebo group. CONCLUSION Baclofen was well tolerated, safe, and effective in the treatment of muscle cramps in patients with liver cirrhosis.

Abstract
Postprandial gastroesophageal reflux (PGER) in the distal esophagus (DE) is associated with a gastric juice 'acid pocket' (AP). Baclofen reduces AP extension into the DE in healthy volunteers, in part through increased lower esophageal sphincter (LES) pressure. We aimed to verify whether baclofen also affects postprandial AP location and extent in gastroesophageal reflux disease (GERD) patients. Thirteen treatment-naive heartburn-prevalent GERD patients underwent two AP studies, after pretreatment with baclofen 40 mg or placebo 30 minutes preprandially. We performed pH-probe stepwise pull-throughs (PT) (1 cm/min, LES -10 to +5 cm) before and every 30 minutes from 30 minutes before up to 150 minutes after a test meal. After the meal, both after placebo and baclofen, gastric pH significantly dropped at 30, 60, 90 minutes postprandially (P: nadir pHs of 3.9 ± 0.6, 2.3 ± 0.6, 2.1 ± 0.4; B: nadir pHs of 2.5 ± 0.4, 2.8 ± 0.4, 2.5 ± 0.3; all P < 0.05). After placebo, LES pressure decreased at 60, 90 and 120 minutes postprandially (32.7 ± 6.1 vs. 24.5 ± 3.1, 27.3 ± 5.9, 27.3 ± 6.0 mmHg; analysis of variance [ANOVA], P = 0.037), but this was prevented by baclofen (25.4 ± 3.4 vs. 29.4 ± 2, 32.2 ± 1.4, 35.5 ± 1.7 mmHg, ANOVA, P = not significant (NS)). Baclofen did not significantly decrease the postprandial AP extent above the LES but prevented the postprandial increase in transient lower esophageal sphincter relaxations (TLESRs) (preprandial vs. postprandial, placebo: 1.1 ± 0.3 vs. 3.7 ± 0.7, P < 0.05; baclofen: 1.4 ± 0.4 vs. 2 ± 0.5, P = NS). In GERD patients, baclofen significantly increases postprandial LES pressure, prevents the increase TLESRs but, unlike in healthy volunteers, does not affect AP extension into the DE.

Abstract
The management of patients with refractory GERD (rGERD) is a major clinical challenge for gastroenterologists. In up to 30% of patients with typical GERD symptoms (heartburn and/or regurgitation), acid-suppressive therapy does not provide clinical benefit. In this Review, we discuss the current management algorithm for GERD and the features and management of patients who do not respond to treatment (such as those individuals with an incorrect diagnosis of GERD, inadequate PPI intake, persisting acid reflux and persisting weakly acidic reflux). Symptom response to existing surgical techniques, novel antireflux procedures, and the value of add-on medical therapies (including prokinetics and reflux inhibitors) for rGERD symptoms are discussed. Pharmaceutical agents targeting oesophageal sensitivity, a condition that can contribute to symptom generation in rGERD, are also discussed. Finally, on the basis of available published data and our expert opinion, we present an outline of a current, usable algorithm for management of patients with rGERD that considers the timing and diagnostic use of pH-impedance monitoring on or off PPI, additional diagnostic tests, the clinical use of baclofen and the use of add-on neuromodulators (tricyclic agents and selective serotonin reuptake inhibitors).

Abstract
In patients with refractory heartburn while on proton pump inhibitor (PPI) therapy, changing drugs or increasing treatment to a twice a day (b.i.d.) dose has become a common practice. This study aims to study patients with persistent heartburn while on PPI therapy and to determine if persistent symptom indicates the need for more aggressive or different therapy. A retrospective review of impedance-pH tracings on PPI therapy (q.d. or b.i.d.) for patients with persistent heartburn was performed. DeMeester score, impedance, and symptom sensitive index (SSI) were used as indices. Statistical analyses were performed using chi-squared test with Yates correction and paired t-test. One hundred consecutive patients, (female 50%, male 50%, mean age 54 [range 16-83] years) were studied on q.d. (n = 45) or b.i.d. PPI (n = 55). Only 20% of the patients had abnormal DeMeester score; 41% had an abnormal impedance score and 56% had abnormal SSI; 29% had all indices normal. There was no difference between patients taking q.d. versus b.i.d. PPI for abnormal DeMeester score (22 vs. 18%), impedance (38 vs. 44%) and SSI (53 vs. 58%); P = 0.80, 0.69, and 0.77, respectively. In 56 patients with positive SSI, symptoms were due to acid reflux in 8 (14%) patients, nonacid reflux in 31 (55%) patients, and combined acid and nonacid reflux in 17 (30%) patients. Patients with persistent heartburn on PPI therapy show a variety of disorders: (i) acid reflux (20%); (ii) nonacid reflux (26%); (iii) positive SSI (56%); (iv) all normal indices (29%). These studies indicate that persistent heartburn on PPI therapy is a complex problem that may not respond to simply increasing acid inhibition.

Abstract
Objective. To describe the evidence for baclofen in the treatment of gastroesophageal reflux disease (GERD). Data Sources. A search of PubMed and Google Scholar was performed using the terms baclofen, gastroesophageal reflux disease, and treatment. Study Selection and Data Extraction. Publications were reviewed manually for relevance, and studies that addressed the use of baclofen in the treatment of adult symptomatic GERD patients were included. Data Synthesis. Nine studies were evaluated. Baclofen was shown to significantly reduce transient lower esophageal sphincter relaxations (TLESRs), postprandial acid reflux events, and median number of acid-related symptoms in 6 studies evaluating either a single dose of baclofen or short courses of 2 days or less. Three studies followed patients over a slightly longer period of time. These studies confirmed the results of the shorter trials by finding a decrease in supine duodenal reflux episodes, decreased periods when the pH was less than 4, and improvements in symptom scores in patients refractory to proton pump inhibitors. Side effects most frequently reported included drowsiness and dizziness. Conclusions. Baclofen can be considered for the treatment of refractory GERD following diagnostic evaluation. It has been shown to reduce TLESRs, reflux episodes, and reflux-related symptoms with minimal side effects in short-term trials. Future studies demonstrating the long-term efficacy and tolerability of baclofen in the treatment of GERD would help solidify its place in therapy.

Abstract
Gastroesophageal reflux disease (GERD) is a very common foregut disease prevalent worldwide. The prevalence of GERD has risen strikingly over the past decades, causing substantial health and economic burdens. Due to high rates of recurrent reflux symptoms, reoperations and complications, surgical therapy of GERD did not attach enough attention in its early stage. However, surgical therapy for GERD was subsequently revolutionized by the development of anti-reflux surgical techniques and the introduction and popularization of minimally invasive surgeries. Anti-reflux surgery has gradually proved to be a well-documented, effective, therapeutic option for GERD by long-term follow-up studies. In order to improve results and to reduce unwanted effects, surgeons should master the indications of surgery and techniques of anti-reflux surgery. Besides, choosing appropriate candidates and surgical approach is also crucial for outcomes. However, limited by the regional economy and surgeon's skill, the use of anti-reflux surgery is still very limited. The aim of this review is to analyze and discuss the current spectrum of surgical therapy of GERD, and to provide orientation for surgeons in the challenging therapy of GERD.

The effects of baclofen for the treatment of gastroesophageal reflux disease: a meta-analysis of randomized controlled trials. Gastroenterol Res Pract 2014; 2014:307805. [PMID: 25389436 PMCID: PMC4217339 DOI: 10.1155/2014/307805] [Citation(s) in RCA: 46] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/21/2014] [Revised: 08/08/2014] [Accepted: 08/27/2014] [Indexed: 12/14/2022] Open
Abstract
Objectives. Baclofen can relieve gastroesophageal reflux-related symptoms in healthy subjects and gastroesophageal reflux disease (GERD) patients by reducing the incidence of transient lower esophageal sphincter relaxation. This meta-analysis aimed to evaluate the efficacy and safety of baclofen for the treatment of GERD. Methods. We systematically searched randomized controlled trials published prior to November 2013 from PubMed, Medline, Embase, ScienceDirect, ClinicalTrials.gov, and the Cochrane Central Register of Randomized Controlled Trials. We performed a meta-analysis of all eligible trials. Results. Nine studies were identified with a total of 283 GERD patients and healthy subjects. Comparative analysis provided high quality data supporting the ability of baclofen to promote a short-term decrease in the number of reflux episodes per patient, the average length of reflux episodes, and the incidence of transient lower esophageal sphincter relaxation. No serious adverse events or death events were reported, and there were no significant differences in the overall adverse events between baclofen and placebo. All reported side effects of baclofen were of mild-to-moderate intensity, and the drug was well tolerated. Conclusion. Abundant evidence suggests that baclofen may be a useful approach for the treatment of GERD patients; however, a larger well-designed research study would further confirm this recommendation.

Abstract
Gastroesophageal reflux disease (GERD) is a common disease with a prevalence as high as 10%-20% in the western world. The disease can manifest in various symptoms which can be grouped into typical, atypical and extra-esophageal symptoms. Those with the highest specificity for GERD are acid regurgitation and heartburn. In the absence of alarm symptoms, these symptoms can allow one to make a presumptive diagnosis and initiate empiric therapy. In certain situations, further diagnostic testing is needed to confirm the diagnosis as well as to assess for complications or alternate causes for the symptoms. GERD complications include erosive esophagitis, peptic stricture, Barrett’s esophagus, esophageal adenocarcinoma and pulmonary disease. Management of GERD may involve lifestyle modification, medical therapy and surgical therapy. Lifestyle modifications including weight loss and/or head of bed elevation have been shown to improve esophageal pH and/or GERD symptoms. Medical therapy involves acid suppression which can be achieved with antacids, histamine-receptor antagonists or proton-pump inhibitors. Whereas most patients can be effectively managed with medical therapy, others may go on to require anti-reflux surgery after undergoing a proper pre-operative evaluation. The purpose of this review is to discuss the current approach to the diagnosis and treatment of gastroesophageal reflux disease.

Abstract
The mainstay of pharmacological therapy for GERD is gastric acid suppression with proton pump inhibitors (PPIs), which are superior to histamine-2 receptor antagonists for healing erosive esophagitis and achieving symptomatic relief. However, up to one-third of patients may not respond to PPI therapy, creating the need for alternative treatments. Potential approaches include transient lower esophageal sphincter relaxation inhibitors, augmentation esophageal defense mechanisms by improving esophageal clearance or enhancing epithelial repair, and modulation of sensory pathways responsible for GERD symptoms. This review discusses the effectiveness of acid suppression and the data on alternative pharmacological approaches for the treatment of GERD.

Abstract
BACKGROUND AND AIM Baclofen, a γ-aminobutyric acid receptor agonist, has been shown to reduce the episodes of gastroesophageal reflux (GER) by reducing the incidence of transient lower esophageal sphincter relaxations. Although baclofen has been shown to reduce reflux symptoms in adults, data in pediatric patients are limited. The aim of the study was to evaluate the efficacy of baclofen in children with refractory GER. METHODS Medical charts of patients 1 to 18 years of age treated with baclofen for persistent GER symptoms were reviewed retrospectively. Short-term (at first clinic visit) and long-term (12 months) clinical responses were assessed. RESULTS A total of 53 patients were included in the final analysis. The mean duration of illness was 1.5 years and the mean age was 6.1 years. All of the patients were taking either once- (53%) or twice-daily (47%) doses of proton pump inhibitors (PPIs) at the time of initiation of baclofen. Thirty-five (66%) patients experienced a significant reduction in clinical symptoms at their first follow-up visit. In the remaining 18 patients, however, baclofen was stopped because of either no response (n = 15) or adverse events (n = 3). A total of 27 patients continued treatment and were assessed for long-term response. Of those, 22 (81%) had a sustained response to baclofen at 12 months, whereas 5 (19%) lost response. We recognized no clinical characteristic differences between those with and without a response to baclofen at either time point. CONCLUSIONS Baclofen can be used as supplemental therapy to proton pump inhibitors in children with refractory GER; however, prospective trials are needed to further validate our results and assess safety.

Abstract
Over the last year, significant steps have been made toward understanding the pathogenesis of esophageal diseases and translating this knowledge to clinical practice. Gastroesophageal reflux disease (GERD) is the most common outpatient diagnosis in gastroenterology and has a high prevalence in the general population. As many as 40% of patients with GERD have incomplete response to medical therapy, and the pathophysiological mechanisms underlying lack of response are now better understood. Novel medical and minimally invasive interventions are available to optimize management of GERD. Esophageal cancer, regardless of the histological subtype, has among the worst survival statistics among all malignancies. Taking advantage of technological advances in genome sequencing, the mutational spectra in esophageal cancer are now emerging, offering novel avenues for targeted therapies. Early diagnosis is another strand for improving survival. While genome-wide association studies are providing insights into genetic susceptibility, novel approaches to early detection of cancer are being devised through the use of biomarkers applied to esophageal samples and as part of imaging technologies. Dysmotility and eosinophilic esophagitis are the differential diagnoses in patients with dysphagia. New pathophysiological classifications have improved the management of motility disorders. Meanwhile, exciting progress has been made in the endoscopic management of these conditions. Eosinophilic esophagitis is still a relatively new entity, and the pathogenesis remains poorly understood. However, it is now clear that an allergic reaction to food plays an important role, and dietary interventions as well as biologic agents to block the inflammatory cascade are novel, promising fields of clinical research.

Abstract
PURPOSE OF REVIEW Gastroesophageal reflux (GER) remains a common, challenging problem for clinicians, with differentiation of normal development from disease a particular issue. This review updates clinicians on advances in diagnosis of GER, relationship to other problems, and current practice in management. RECENT FINDINGS Development and understanding of multichannel intraluminal impedance-pH monitoring has given insights into the relationship of GER to symptoms. Medical treatment has changed little. Avoidance of overmedicalizing normal development is the major issue for clinicians. Laparoscopic fundoplication is established as equivalent to open fundoplication. Newer endoscopic techniques have only limited use in children to date. SUMMARY Major changes in pediatric GER relate to understanding of physiology and relationship of GER to symptoms. The major challenge for clinicians involve differentiation of normal from abnormal GER, and applying the most relevant management.

Abstract
This study investigated whether the complaint of night-time heartburn (NHB) as opposed to daytime heartburn (DHB) is a reliable reflection of actual sleep-related reflux events. Three groups of individuals were studied: individuals with complaints of NHB at least twice per week (n = 24), individuals with complaints of DHB (n = 23), and normal participants without any complaints of regular heartburn during the day or night (n = 25). All three groups were studied on one occasion with combined pH monitoring and polysomnography, and subjective questionnaires about sleep disturbance and sleep quality were given to all participants. The NHB group had significantly more sleep-related reflux events compared with both DHB and control groups (P < 0.01). DHB subjects had significantly (P < 0.05) more sleep-related reflux events than normal controls. Total acid contact time (ACT) was significantly (P < 0.05) elevated in the NHB group compared with both the DHB and control group. Sleep-related ACT was also significantly (P < 0.05) elevated in the NHB group compared with the other two groups, while upright (daytime) ACT was not significantly different. The NHB group was significantly (P < 0.05) worse regarding measures of both objective and subjective sleep quality. Subjects with exclusively DHB do have sleep-related reflux that is greater than normal controls. Subjects with NHB have significantly more sleep-related reflux, and both objective and subjective sleep abnormalities compared with normal controls. Complaints of NHB reflect sleep-related reflux events and may be indicative of a more clinically significant condition.

Abstract
Gastroesophageal reflux disease (GERD), a common disorder with troublesome symptoms caused by reflux of gastric contents into the esophagus, has adverse impact on quality of life. A variety of medications have been used in GERD treatment, and acid suppression therapy is the mainstay of treatment for GERD. Although proton pump inhibitor is the most potent acid suppressant and provides good efficacy in esophagitis healing and symptom relief, about one-third of patients with GERD still have persistent symptoms with poor response to standard dose PPI. Antacids, alginate, histamine type-2 receptor antagonists, and prokinetic agents are usually used as add-on therapy to PPI in clinical practice. Development of novel therapeutic agents has focused on the underlying mechanisms of GERD, such as transient lower esophageal sphincter relaxation, motility disorder, mucosal protection, and esophageal hypersensitivity. Newer formulations of PPI with faster and longer duration of action and potassium-competitive acid blocker, a newer acid suppressant, have also been investigated in clinical trials. In this review, we summarize the current and developing therapeutic agents for GERD treatment.

Abstract
Gastro-oesophageal reflux disease develops when the reflux of gastric contents into the oesophagus results in troublesome symptoms and/or complications [1]. Refluxate contains predominantly acid which causes tissue injury at oesophageal and extra-oesophageal sites. It is one of the commonest gastrointestinal diagnosis worlds over. It is associated with chronic symptoms, reduced QOL, significant cost and serious complications. Goals of therapy are to provide symptom relief, heal oesophagitis and prevent long-term complications. Therapeutic measures are directed at reducing the noxiousness of the refluxate; reducing the gastro-oesophageal reflux; enhancing clearance; protecting the mucosa; reducing the mucosal sensitivity and improving healing. Acid suppression with proton pump inhibitors remains the cornerstone of therapy. Recent studies have resulted in better understanding of disease and relative efficacies of various strategies. This has paved way for a better evidence based approach. The therapy however needs to be individualized depending upon the clinical profile, disease severity, the dominant pathophysiological mechanism, cost, availability and individual preferences.

Abstract
There is strong evidence of a bidirectional relationship between gastroesophageal reflux disease and sleep disturbances. Gastroesophageal reflux (GER) events during the night result in sleep disturbances that include difficulty in falling asleep, sleep fragmentation, and early morning awakenings. In addition, sleep deprivation per se induces hyperalgesia of the esophageal mucosa in response to acid. Treatment includes lifestyle modifications, proton-pump inhibitors (PPIs), γ-aminobutyric acidB agonists, hypnotics, and antireflux surgery. Among these, PPIs are considered first-line treatment for the control of nighttime gastric acid secretion; however, the timing and dosing of PPI administration should be individualized for each patient.

Abstract
BACKGROUND It has been reported that baclofen, a drug used in the treatment of spasticity, reduces the severity of withdrawal symptoms and substance use disorders (SUDs) for some psychoactive drugs. AIMS AND METHODS To evaluate the effectiveness and safety of baclofen in the treatment of withdrawal syndrome and/or SUDs, providing (1) an outline of its pharmacological features; (2) a summary of studies that have suggested its possible effectiveness in the treatment of SUDs, and (3) a review of randomized, controlled trials (RCTs) on baclofen and SUDs. RESULTS Baclofen tolerability is generally considered to be good. Eleven RCTs investigated its effectiveness in the treatment of SUDs. Of these, 5 RCTs found that baclofen is effective, 5 RCTs found that it is ineffective and the results of 1 RCT were not appreciable because it did not achieve the preplanned level of participation. CONCLUSIONS The number of RCTs on baclofen and SUDs is still low, and their results are divergent. Further RCTs should be undertaken, particularly with higher doses of baclofen. Its administration may be suggested in patients who fail to respond to other approved drugs or who are affected by liver disease that prevents their administration, or in patients affected by SUDs for which no approved drugs are available. Treatment should be conducted under strict medical supervision.
