RESUMO
BACKGROUND: Diabetes Mellitus (DM) is known to induce a wide range of harmful effects on several organs, notably leading to ineffective esophageal motility (IEM). However, the relationship between DM and IEM is not fully elucidated. We aimed to determine the relationship between DM and IEM and to evaluate the impact of DM's end organ complications on IEM severity. METHODS: A multicenter cohort study of consecutive patients undergoing high-resolution esophageal manometry (HREM) was performed. We reviewed medical records of patients diagnosed with IEM using HREM, encompassing data on demographics, DM history, antidiabetic and other medications as well as comorbidities. KEY RESULTS: Two hundred and forty six subjects met the inclusion criteria. There was no significant difference in any of the HREM parameters between diabetics and nondiabetics. Out of 246 patients, 92 were diabetics. Diabetics with neuropathy presented a significantly lower distal contractile integral (DCI) value compared to those without neuropathy (248.2 ± 226.7 mmHg·cm·sec vs. 375.6 ± 232.4 mmHg·cm·sec; p = 0.02) Similarly, the DCI was lower in diabetics with retinopathy compared to those without retinopathy (199.9 ± 123.1 mmHg·cm·sec vs. 335.4 ± 251.7 mmHg·cm·sec; p = 0.041). Additionally, a significant difference was observed in DCI values among DM patients with ≥2 comorbidities compared to those without comorbidities (224.8 ± 161.0 mmHg·cm·sec vs. 394.2 ± 243.6 mmHg·cm·sec; p = 0.025). Around 12.6% of the variation in DCI could be explained by its linear relationship with hemoglobin A1c (HbA1c), with a regression coefficient (ß) of -55.3. CONCLUSION & INFERENCES: DM is significantly associated with IEM in patients with neuropathy, retinopathy, or multiple comorbidities. These results are pivotal for tailoring patient-specific management approaches.

BACKGROUND AND AIMS: Postprandial diarrhea (PPD) is commonly seen in patients with disorders of gut-brain interaction (DGBI), but the factors associated with it have not been well studied. In this study, we aim to study the burden, impact, and predictors of PPD using a clinical cohort of DGBI patients. METHODS: This study included patients with chronic diarrhea fulfilling ROME IV criteria for irritable bowel syndrome (IBS) or functional diarrhea (FDiarr). PPD was defined as patients reporting mushy/watery stools following meals ≥30% of the time in the last 3 months using a ROME IV question on PPD. Age, sex, and BMI, the severity of diarrhea, abdominal pain, depression, anxiety, somatization, and quality of life were assessed using validated measures. Person's chi-square test and Student's t-test were used to compare variables. A multiple linear regression model with backward elimination was done to determine predictors of PPD severity. KEY RESULTS: Of 213 eligible patients, more than three-fourth of patients (75.6%) had PPD. Women (79.0%, p = 0.037), patients with ROME IV diagnosis of IBS-D (90.5%, p = 0.002), and functional dyspepsia (83.2%, p = 0.014), and those with a history of cholecystectomy (CCY) (95.5%, p = 0.022) were more likely to report PPD. PPD patients experienced more severe abdominal pain, diarrhea, and decreased quality of life (QoL) but showed no significant difference in BMI, anxiety, depression, sleep, or somatization. In our regression model, female sex and history of CCY were independent predictors of PPD. CONCLUSIONS AND INFERENCES: PPD is frequently reported among chronic diarrhea patients and is associated with more severe GI symptoms and decreased QoL. Female sex and CCY predict PPD, while psychological factors do not.

BACKGROUND & AIMS: Chronic gastrointestinal (GI) symptoms are a common reason for seeking medical care. We aim to determine the rates of ambulatory care use and to characterize demographics, work-up, and treatment (pharmacologic and nonpharmacologic) for patients with chronic upper GI symptoms and conditions in the United States. METHODS: Estimates of annual visits for the most common upper GI symptoms and diagnoses including gastroesophageal reflux disease, dyspepsia, nausea and vomiting, and gastroparesis were recorded from the 2007-2015 National Ambulatory Medical Care Surveys. Only chronic conditions, defined as >3 months, were included. We calculated the weighted proportion of ambulatory visits associated with pharmacologic, nonpharmacologic treatment (eg, diet, complementary and alternative medicine), or both. RESULTS: A total of 116,184,475 weighted ambulatory visits were identified between the years of 2007 and 2015 for adults (average of 12,909,386 annual visits) with chronic upper GI symptoms and diagnoses. Gastroesophageal reflux disease was the most common reason for an ambulatory visit (n = 11,200,193), followed by dyspepsia (n = 1,232,598), nausea and vomiting (n = 714,834), and gastroparesis (n = 140,312). Pharmacologic treatment was more common than nonpharmacologic treatment (44.7% vs 28.5%). A total of 37.6% of patients were not receiving treatment at the time of the visit. These treatment patterns did not significantly change over the time of our study. Upper endoscopies were the most ordered test, representing 7.5% of all investigated upper GI symptoms. CONCLUSIONS: Chronic upper GI symptoms and diagnoses account for a high number of annual health care visits, both in primary care and specialty care. Although there are several treatments, many of these patients are not on any treatments.

BACKGROUND: Tetrahydrocannabinol, the main psychoactive compound in cannabis, binds with high affinity to the cannabinoid 1 receptor. Small randomized controlled studies using conventional manometry have shown that the cannabinoid 1 receptor can modulate esophageal function, namely transient lower esophageal sphincter relaxation frequency and lower esophageal sphincter tone. The effect of cannabinoids on esophageal motility in patients referred for esophageal manometry has not been fully elucidated using high-resolution esophageal manometry (HREM). We aimed to characterize the clinical effect of chronic cannabis use on esophageal motility utilizing HREM. METHODS: Patients who underwent HREM from 2009 to 2019 were identified at 4 academic medical centers. The study group consisted of patients with a noted history of chronic cannabis use, a diagnosis of cannabis-related disorder, or a positive urine toxicology screen. Age and gender-matched patients with no history of cannabis use were selected to form the control group. Data on HREM metrics based on the Chicago classification V3, and the prevalence of esophageal motility disorders were compared. Confounding effects of BMI and medications on esophageal motility were adjusted for. RESULTS: Chronic cannabis use was found to be an independent negative predictor of weak swallows (ß=-8.02, P =0.0109), but not a predictor of failed swallows ( P =0.6890). The prevalence of ineffective esophageal motility was significantly lower in chronic cannabis users compared with nonusers (OR=0.44, 95% CI 0.19-0.93, P =0.0384). There was no significant difference in the prevalence of other esophageal motility disorders between the 2 cohorts. In patients with dysphagia as their primary indication for HREM, chronic cannabis use was found to be independently associated with increased median integrated relaxation pressure (ß=6.638, P =0.0153) and increased mean lower esophageal sphincter resting pressure (ß=10.38, P =0.0084). CONCLUSIONS: Chronic cannabis use is associated with decreased weak swallows and reduced prevalence of ineffective esophageal motility in patients referred for esophageal manometry. In patients referred for dysphagia, chronic cannabis use is associated with increased integrated relaxation pressure and lower esophageal sphincter resting pressure, though not to levels above the normal range.

BACKGROUND & AIMS: Bloating is a common symptom in the general population and among disorders of gut-brain interaction, although its prevalence has not been well characterized. The aim of this study was to report the prevalence of bloating as a symptom in the worldwide population and to identify factors associated with this symptom in the general population. METHODS: Rome Foundation Global Epidemiology Study internet survey data were analyzed. After excluding respondents with potential organic causes of bowel symptoms, the current analysis included 51,425 individuals in 26 countries. Data included diet, medical history, quality of life, and Rome IV diagnostic questions. Presence of bloating was defined as experiencing bloating at least once per week for the last 3 months. Descriptive statistics estimated prevalence by country, region, and disorder of gut-brain interaction diagnosis. Logistic regression evaluated predictors of bloating. RESULTS: Nearly 18% of the global study population reported bloating (ranging from 11% in East Asia to 20% in Latin America). Prevalence decreased with age and women were approximately twice as likely as men to report bloating. More than one-half of respondents who reported weekly epigastric pain (71.39%), nausea (59.7%), or abdominal pain (61.69%) also reported bloating at least once per week. In logistic regression, the strongest associations were with abdominal pain (odds ratio, 2.90) and epigastric pain (odds ratio, 2.07). CONCLUSIONS: Bloating is common throughout the world. Nearly 18% of the general population experience bloating at least once per week. Reported bloating prevalence is lower in older age groups, most common in women, and strongly associated with abdominal pain.

INTRODUCTION: Unspecified functional bowel disorder (FBD-U) is a Rome IV diagnosis of exclusion and occurs when patients report bowel symptoms but do not meet the criteria for other functional bowel disorders (FBD; irritable bowel syndrome [IBS], functional constipation [FC], functional diarrhea [FDr], or functional bloating). Previous research suggests that FBD-U is as/more common than IBS. METHODS: One thousand five hundred one patients at a single-center tertiary care center completed an electronic survey. Study questionnaires included Rome IV Diagnostic Questionnaires, anxiety, depression, sleep, health care utilization, and bowel symptom severity measures. RESULTS: Eight hundred thirteen patients met Rome IV criteria for a FBD and 194 patients (13.1%) met criteria for FBD-U, representing the second most common FBD after IBS. Severity of abdominal pain, constipation, and diarrhea were lower in FBD-U compared with other FBD, whereas health care utilization was similar among the groups. Scores on measures of anxiety, depression, and sleep disturbances were similar in FBD-U compared with FC and FDr but were less severe than IBS. Between 25% and 50% of patients with FBD-U did not meet Rome IV criteria for other FBD due to timing of onset of the target symptom (e.g., constipation for FC, diarrhea for FDr, and abdominal pain for IBS). DISCUSSION: FBD-U, by Rome IV criteria, is highly prevalent in clinical settings. These patients are not represented in mechanistic studies or clinical trials for not having met Rome IV criteria for other FBD. Making future Rome criteria less stringent would minimize the number fulfilling criteria for FBD-U and maximize the true representation of FBD in clinical trials.

BACKGROUND: Hyperemesis gravidarum is the most severe form of nausea and vomiting of pregnancy, potentially affecting both maternal and pregnancy health. Hyperemesis gravidarum often results in emergency department visits, although the exact frequency and costs associated with these visits have not been well studied. OBJECTIVE: This study aimed to analyze the trends in hyperemesis gravidarum emergency department visits, inpatient admissions, and the associated costs between 2006 and 2014. STUDY DESIGN: Patients were identified from the 2006 and 2014 Nationwide Emergency Department Sample database files using International Classification of Diseases, Ninth Revision diagnosis codes. Patients with a primary diagnosis of hyperemesis gravidarum, nausea and vomiting of pregnancy, and all nondelivery pregnancy-related diagnoses (all antepartum visits) were identified. All groups were analyzed; trends in demographics, number of emergency department visits, and visit costs were compared. Costs were inflation-adjusted to 2021 US dollars. RESULTS: Emergency department visits for hyperemesis gravidarum increased by 28% from 2006 to 2014; however, the proportion of those who were subsequently admitted to the hospital decreased. The average cost of an emergency department visit for hyperemesis gravidarum increased by 65% ($2156 to $3549), as opposed to an increase of 60% for all antepartum visits ($2218 to $3543). The aggregate cost for all hyperemesis gravidarum visits increased by 110% ($383,681,346 to $806,696,513) from 2006 to 2014, which was similar to the increase observed for all antepartum emergency department visits. CONCLUSION: From 2006 to 2014, emergency department visits for hyperemesis gravidarum increased by 28%, with associated costs increasing by 110%, whereas the number of admissions from the emergency department for hyperemesis gravidarum decreased by 42%.
RESUMO
Background/Aims: Presently, there is paucity of information about clinical predictors, especially esophageal motor abnormalities, for long segment Barrett's esophagus (LSBE) as compared with short segment Barrett's esophagus (SSBE). The aims of this study are to compare the frequency of esophageal function abnormalities between patients with LSBE and those with SSBE and to determine their clinical predictors. Methods: This was a multicenter cohort study that included all patients with a diagnosis of BE who underwent high-resolution esophageal manometry. Motility disorders were categorized as hypercontractile disorders or hypocontractile disorders and their frequency was compared between patients with LSBE and those with SSBE. Multivariable logistic regression modeling was used to calculate the odds of being diagnosed with LSBE relative to SSBE for demographics, comorbidities, medication use, endoscopic findings, and the type of motility disorders. Results: A total of 148 patients with BE were identified, of which 89 (60.1%) had SSBE and 59 (39.9%) LSBE. Patients with LSBE had a significantly larger hiatal hernia and higher likelihood of erosive esophagitis than patients with SSBE (P = 0.002). Patients with LSBE had a significantly lower mean LES resting pressure, distal contractile integral, distal latency, and significantly higher failed swallows and hypocontractile motility disorders than those with SSBE (P < 0.05). Hiatal hernia and hypocontractile motility disorder increased the odds of LSBE by 38.0% and 242.0%, as opposed to SSBE. Conclusions: The presence of a hypocontractile motility disorder increased the risk for LSBE. Furthermore, the risk for LSBE was directly associated with the length of the hiatal hernia.
RESUMO
INTRODUCTION: Ineffective esophageal motility (IEM) is the most common motility disorder identified on esophageal high-resolution manometry (HRM), but patients with this finding may be asymptomatic. Therefore, we aimed to identify specific HRM findings predictive of symptoms in IEM. METHODS: Adult patients (≥18 y) who underwent HRM between March 2016 and July 2019 were retrospectively evaluated and reclassified according to Chicago Classification 4.0 (CC4.0). Demographic information, HRM parameters, and gastroesophageal reflux disease Health-Related Quality of Life Questionnaire responses were captured among those with normal manometry or IEM. We evaluated the association between heartburn, regurgitation, and dysphagia, with respect to HRM findings including ineffective swallows. RESULTS: Of 379 patients, 243 (64.1%) had a normal manometry, 136 (35.9%) were on IEM spectrum, and 73 (19.3%) had conclusive IEM by CC4.0. Mean dysphagia scores were significantly higher in those with conclusive IEM compared with those with normal HRM (2.00 vs. 1.36, P =0.002), as was the percentage of individuals reporting dysphagia affecting daily activities (21.9% vs. 11.4%, P =0.02). Heartburn and regurgitation symptoms did not differ between groups. In a multivariable model of IEM patients, the percentage of ineffective swallows independently predicted a higher dysphagia burden (ß regression coefficient: 0.032, P =0.04). CONCLUSIONS: Applying the CC4.0 definition for conclusive IEM identifies a group of patients with worse dysphagia symptoms. Within this group, the percentage of ineffective swallows was an independent predictor of dysphagia severity. These findings may help practitioners and patients contextualize the heterogeneous diagnosis of IEM.

BACKGROUND: The estimated prevalence of bloating is 15 to 30% in the adult US population and is even higher in patients with disorders of gut-brain interaction (DGBIs). Despite this frequency, there is little research into patients who endorse bloating as a predominant symptom. The aim of this study was to better characterize these patients. MATERIALS AND METHODS: New patients with DGBIs were asked to identify their 3 most predominant symptoms over the preceding 3 months; those who reported bloating were classified as "bloating predominant." Rome IV and symptom-specific questionnaires were administered to assess for the frequency of DGBIs and other predominant symptoms in this patient population. Using univariable and multivariable modeling, we analyzed the associations between bloating predominance, DGBI subtype, and clinical characteristics. RESULTS: Of the 586 patients surveyed, 242 (41%) reported predominant bloating. Bloating-predominant patients were more likely to be female, younger, and meet the criteria for IBS-mixed (IBS-M), functional constipation, and functional dyspepsia compared with nonbloating-predominant patients. Bloating-predominant patients were also more likely to endorse concurrently predominant constipation, incomplete evacuation, abdominal pain, belching, and/or nausea. On multivariable logistic regression, constipation and abdominal pain severity were positively associated, although depression was negatively associated with predominant bloating. CONCLUSIONS: Patients with predominant bloating are more likely to have constipation-related symptoms than diarrhea-related symptoms. They are also more likely to have more severe abdominal pain than patients without predominant bloating. These findings help characterize patients with bloating as a predominant symptom and suggest that diagnosing and treating constipation should be considered as first-line treatment.

OBJECTIVE: There is growing evidence that open-label placebo (OLP) may be an efficacious treatment of chronic and functional conditions. However, patient-level predictors of response to OLP have not been clearly identified. The aim of this study is to evaluate the psychological predictors of response to OLP and to compare this to double-blind placebo (DBP) and no-pill control (NPC). METHODS: This study is a secondary analysis of data collected in a 6-week randomized controlled trial evaluating placebo effects in irritable bowel syndrome (IBS). The primary outcome was change in IBS severity. Hierarchical linear regression identified predictors of placebo response in general and compared them between those randomized to OLP, DBP, and NPC. Predictor variables included personality traits, generalized anxiety, depression, visceral sensitivity (a measure of symptom-specific anxiety), and pain catastrophizing. RESULTS: A total of 210 participants (mean age = 42.3 years, 73.3% female) were included. Regression models revealed that visceral sensitivity was a predictor of response to OLP and NPC but not DBP. Interestingly, the effects were opposite, with high visceral sensitivity predicting less improvement in NPC and more improvement in OLP. Pain catastrophizing was a negative predictor of response to OLP (i.e., high pain catastrophizing was associated with less improvement in OLP). Neither visceral sensitivity nor pain catastrophizing played a significant role for response to DBP. CONCLUSIONS: IBS participants who score low on the Pain Catastrophizing Scale but high on the Visceral Sensitivity Index seem to benefit particularly from OLP. Our study suggests that different psychological mechanisms may be involved in DBP and OLP interventions.

BACKGROUND & AIMS: Many of the reported adverse events in clinical trials of irritable bowel syndrome are extraintestinal symptoms, which typically are assessed by open-ended questions during the trial and not at baseline. This may lead to misattribution of some pre-existing symptoms as side effects to the treatment. METHODS: The current study analyzed data from a 6-week clinical trial of irritable bowel syndrome. Participants were randomized to receive double-blind peppermint oil, double-blind placebo, or treatment as usual. Extraintestinal symptoms were assessed at baseline and at the end of the study. RESULTS: This analysis included 173 participants (30 received double-blind peppermint oil, 72 received treatment as usual, and 71 received double-blind placebo). At baseline, each group reported approximately 5 extraintestinal symptoms per participant. The number of symptoms per participant decreased to an average of 3 by the end-of-study visit, and this change was statistically significant in all groups (P < .001 for each group). When evaluating individual extraintestinal symptoms, the majority of participants did not report new/worse symptoms. In fact, between the baseline assessment and the final assessment, the average symptom severity decreased significantly in all 3 groups (P < .001). CONCLUSIONS: Our study suggests that participants with irritable bowel syndrome often experience extraintestinal symptoms at baseline and that these symptoms generally improve in severity over the course of a clinical trial, regardless of the treatment arm. Systematic assessment of extraintestinal symptoms at the beginning of a clinical trial is necessary to determine more definitively whether these symptoms may be considered an adverse event attributable to a study medication.

BACKGROUND: There is increasing evidence suggesting that open-label placebo (OLP) is an effective treatment for several medical conditions defined by self-report. However, little is known about patients' experiences with OLP, and no studies have directly compared patients' experiences in double-blind placebo (DBP) conditions. METHODS: This study was nested in a large randomized-controlled trial comparing the effects of OLP and DBP treatments in individuals with irritable bowel syndrome (IBS). We randomly selected 33 participants for interviews concerning their experiences in the parent trial. The data were qualitatively analyzed using an iterative immersion/crystallization approach. We then compared the qualitative interview data to the quantitative IBS severity data assessed during the parent trial, using a mixed methods approach. RESULTS: Two prominent interview themes were identified: (1) the participants' feelings about their treatment allocation and (2) their reflections about the treatment. Both OLP and DBP participants mentioned hope and curiosity as major feelings driving them to engage with their treatment. However, while DBP participants tended to be more enthusiastic about their allocation, OLP participants were more ambivalent. Furthermore, OLP participants reflected more on their treatment, often involving noticeable cognitive and emotional processes of self-reflection. They offered a variety of explanations for their symptom improvement and were significantly less likely to attribute it to the treatment itself than DBP participants (Χ2 [3] = 8.28; p = .041). Similarly, the participants' retrospective narratives of symptom improvement were significantly correlated with their corresponding quantitative IBS severity scores only in DBP (p's ≤ .006) but not in OLP (p's ≥ .637). CONCLUSION: OLP and DBP participants share feelings of hope, uncertainty and curiosity but differ in the extent of conscious reflection. The counter-intuitive OLP prompts more self-examination, ambivalent feelings and active engagement compared to DBP. At the same time, OLP participants are more reluctant to attribute symptom improvement to their treatment. Our findings substantially add to the emerging picture of factors that distinguish OLP and DBP and their potential mechanisms.

INTRODUCTION: Gastroesophageal reflux has been associated with idiopathic pulmonary fibrosis (IPF). Mean nocturnal baseline impedance (MNBI) is a marker of esophageal mucosal integrity, whereas postreflux swallow-induced peristaltic wave (PSPW) index reflects esophageal chemical clearance. Both metrics offer novel ways to assess reflux burden on multichannel intraluminal impedance-pH testing (MII-pH), but their role in extraesophageal reflux remains unclear. We aimed to evaluate the relationship between these novel metrics and lung function decline in patients with IPF. METHODS: Adults with IPF undergoing prelung transplant MII-pH were enrolled. All patients completed pulmonary function testing (PFT) at the time of MII-pH and at the 1-year follow-up. MNBI was calculated by averaging baseline impedance at three 10-minute intervals (1 AM/2 AM/3 AM). PSPW index was the proportion of all reflux episodes, followed by a peristaltic swallow within 30 seconds. Univariate (Student t-test/Pearson correlation) and multivariable (general linear regression) analyses were performed. RESULTS: One hundred twenty-five subjects (mean age = 61.7 years, 62% men) were included. Forced expiratory volume in one second and forced vital capacity declined more significantly over 12 months in subjects with lower distal MNBI, proximal MNBI, and PSPW index (all P < 0.05). On multivariable analyses adjusting for age, sex, proton pump inhibitor use, and baseline lung function, distal MNBI (ß = -10.86, P = 0.024; ß = -8.03, P = 0.045), proximal MNBI (ß = -13.5, P = 0.0068; ß = -9.80, P = 0.025), and PSPW index (ß = -18.1, P = 0.010; ß = -12.55, P = 0.050) remained predictive of greater forced expiratory volume in one second and forced vital capacity decline. DISCUSSION: Low distal MNBI, proximal MNBI, and PSPW index independently predicted more severe lung function decline over 1 year in patients with IPF. These impedance metrics may have prognostic value and support a role for reflux in IPF pathogenesis.

BACKGROUND & AIMS: Symptoms of functional dyspepsia (FD) fluctuate over time but there are limited data on the impact of factors on change in dyspepsia symptom severity over time. We aimed to evaluate the demographic, clinical, and psychological factors associated with change in dyspepsia symptom severity. METHODS: Consecutive patients with FD presenting to a tertiary care center completed questionnaires assessing clinical and psychological symptoms at the time of the initial visit (baseline) and 3- to 6-month follow-up evaluations. FD and irritable bowel syndrome (IBS) were diagnosed using Rome IV criteria. FD severity was measured using patient assessment of gastrointestinal symptom severity. Patient-reported outcome measures information scales were used to assess the severity of anxiety, depression, and sleep disturbance. RESULTS: Of 128 FD patients, 64 (50%) also met Rome IV criteria for IBS. In the final multivariable model, lower baseline sleep disturbance, improvement in anxiety scores, absence of IBS, and a lower number of medications taken for gastrointestinal symptoms were associated with improvement in dyspepsia scores (P < .05 for all). Conversely, higher baseline dyspepsia severity was associated with greater improvement in dyspepsia severity at follow-up evaluation (P < .001). CONCLUSIONS: Improvement in FD symptom severity over 3 to 6 months was associated with improvement of anxiety, lower sleep disturbance at baseline, absence of IBS, and higher baseline dyspepsia severity.

PURPOSE: Belching is a common condition that frequently overlaps with other functional gastrointestinal disorders. While not associated with any increase in mortality, it is associated with impaired health-related quality of life. Management is challenging, as there are no pharmacologic therapies specifically targeted towards this disorder. This review covers pathogenesis, prevalence, and treatments for this condition, with specific emphasis on the evolving role of behavioral treatments in management. KEY FINDINGS: The diagnosis of gastric and supragastric belching can usually be made clinically, without the need for invasive testing. If necessary, multichannel intraluminal impedance and pH testing can provide a more definitive diagnosis and can also be used to estimate the frequency of gastric and supragastric belching episodes, which each have a distinct appearance on impedance tracing. Belching disorders are commonly associated with gastroesophageal reflux disease and functional disorders of the gastrointestinal tract. Supragastric belching is also associated with behavioral disorders like anxiety and obsessive-compulsive disorder. Speech therapy, cognitive-behavioral therapy, and diaphragmatic breathing are all interventions that have recently shown promise in the management of this challenging disorder.

OBJECTIVES: Tricyclic antidepressants (TCAs) are commonly used to treat disorders of gut-brain interaction (DGBI). However, these medications are often associated with side effects that lead to early treatment discontinuation. Research in other chronic medical conditions suggests that many TCA side effects may be caused by nocebo (negative placebo) effects. The current study tests a brief, verbal intervention aimed at improving tolerance of TCAs in DGBI by providing education about nocebo effects. MATERIALS AND METHODS: This pilot randomized controlled trial was performed in a tertiary care gastroenterology clinic. Participants with DGBI were randomized "standard information," describing the benefits and risks of TCAs, or "augmented information," which included an additional <30-second education about nocebo effects. Two weeks after their visit, participants were emailed a survey evaluating the number and bothersomeness of side effects, adequate relief, global improvement, and treatment satisfaction. RESULTS: Thirty-one patients were randomized and 22 responded to the survey. The average age was 40% and 59% were women. Although not statistically significant, the augmented group attributed nominally fewer symptoms to TCAs than the standard group, with a medium effect size (1.5 vs. 4.2, effect size d=0.56, P=0.212) and reported being significantly less bothered by those symptoms (13.4 vs. 38.1, P=0.037). A nominally larger percentage of the augmented group reported adequate relief of symptoms after 2 weeks of treatment compared with the standard group (55% vs. 27%, respectively). CONCLUSIONS: This pilot study demonstrates that a brief (≈30 s) clinical intervention addressing nocebo effects may improve tolerance of TCAs. These findings provide support for future, fully powered studies to evaluate the impact of framing on clinical outcomes, especially in chronic conditions.

BACKGROUND: Abdominal pain is a bothersome and lifestyle limiting symptom in patients with functional bowel disorders. It is associated with decreased quality of life in affected individuals, as well as significant annual healthcare expenditure. Knowledge of specific factors that predict improvement in abdominal pain in those with functional bowel disorders is thus far limited. METHODS: Consecutive patients presenting for outpatient care at a major academic medical center between October 2017 and March 2020 completed an electronic symptom survey prior to initial clinic visit, and again after 3 months. The Rome IV questionnaires for functional dyspepsia, irritable bowel syndrome, functional constipation, and functional diarrhea were all included. Additionally, all subjects completed the Patient Reported Outcomes Measurement Information System Anxiety, Depression, and sleep disturbance questionnaires. Patients with a diagnosis of a Rome IV functional gastrointestinal disorder without any organic cause for symptoms were identified based on both chart review as well as survey response data. Univariable and multivariable analysis was used to assess predictors of improved abdominal pain after 3 months. KEY RESULTS: 180 patients with a mean age of 45.3 years were included in the final analysis. 78.3% of patients were female, and 77.2% met Rome IV criteria for irritable bowel syndrome. On multivariable analysis, improvement in constipation and diarrhea were both independent predictors of improved abdominal pain after 3 months. CONCLUSIONS AND INFERENCES: Improvement in constipation and diarrhea both predicted improvement in abdominal pain, suggesting that addressing these factors is central to the management of abdominal pain in functional gastrointestinal disorders.

INTRODUCTION: Peppermint oil is often used to treat irritable bowel syndrome (IBS); however, the overall quality of previous studies is low, and findings have been heterogeneous. This study aimed to compare the effects of peppermint oil vs placebo in relieving IBS symptoms. METHODS: In a 6-week, randomized, double-blind, placebo-controlled trial at a single academic center in the United States, individuals diagnosed with IBS (Rome IV criteria), with moderate to severe symptoms based on the IBS Severity Scoring System (IBS-SSS score ≥175), were randomized to enteric-coated peppermint oil 180 mg 3 times daily vs placebo in a 1:2 ratio. The primary outcome was mean change in IBS-SSS scores from baseline to 6-week endpoint. RESULTS: A modified intent-to-treat analysis revealed that there were substantial mean improvements from baseline to 6-week endpoint in the main outcome measure (IBS-SSS) for both peppermint oil (90.8, SD = 75.3) and placebo (100.3, SD = 99.6). Although the peppermint oil group reported numerically lower improvement than the placebo group, the effect size was small (d = -0.11), and the difference between the groups was not statistically significant (P = 0.97). Similarly, both groups reported substantial improvements on the secondary endpoints; but again, there were no statistically significant differences between the groups on any of the secondary measures. Sensitivity analyses using multiple imputation to replace missing data produced similar results and revealed no significant differences between peppermint oil and placebo on any outcome measure. DISCUSSION: Peppermint oil and placebo both showed clinically meaningful improvement in IBS symptoms. However, there were no significant differences between the groups. Further large, rigorous trials are needed to evaluate the role of peppermint oil for the treatment of IBS.
