Total Gastrointestinal Symptom Rating Scale Research Articles

The Gastrointestinal Symptom Rating Scale has a Good Test-Retest Reliability in Well-Trained Athletes With and Without Previously Self-Identified Gastrointestinal Complaints.

Athletes often report gastrointestinal (GI) complaints. Standardized validated tests validated in athletes are lacking. The objective of the current study was to investigate the test-retest reliability of the gastrointestinal symptoms rating scale (GSRS), a disease-specific instrument of 15 items to quantify the severity of various GI symptoms. For this purpose, a 3-week repeated measurements design was used. The mean difference (Wilcoxon signed rank test), associations (Spearman correlations), and systematic difference using Bland-Altman calculations for repeated measurements, as well as its internal consistency (Cronbach's alpha) on testing day 1 and day 2 were analyzed, with significance set at p ≤ 0.05. A total of n = 70 well-trained athletes (26.1 ± 5.4years, of which 40% were female) were included. A high Cronbach's α for GSRS was found on testing day 1 (0.825), and day 2 (0.823), suggesting a good and comparable internal consistency of the questionnaire. When assessing the multilevel temporal stability for total GSRS scores (28.0, IQR 22.0-36.3 vs 26.5, IQR 18.0-35.0), there was a small but significant difference (Z = - 2.489, and p = 0.013), but a fair correlation between day scores (r = 0.68, p < 0.001), and a Bland-Altman reporting difference between questionnaires within 10% of the total GSRS score, without significant reporting bias (p = 0.38). In most cases, except for hunger, burping, and loose stools, the individual GSRS items were reported in line with total scores and similar for sex. In conclusion, the GSRS is reliable when used with athletes, with good internal consistency for most symptoms independently of sex, except for hunger, burping, and loose stools.

Postbariatric hypoglycemia, abdominal pain and gastrointestinal symptoms after Roux-en-Y gastric bypass explored by continuous glucose monitoring.

BackgroundAbdominal pain and postbariatric hypoglycemia (PBH) are common after bariatric surgery. ObjectivesThis study aimed to explore the potential relationship between abdominal pain, gastrointestinal symptoms, and PBH more than a decade after Roux-en-Y gastric bypass (RYGB) and whether continuous glucose monitoring (CGM) with dietary intervention has an educational role in reducing symptoms. SubjectsAt two public hospitals in Norway (one University Hospital) 22 of 46 invited patients who reported abdominal pain more than weekly took part. Recruited from a prospective follow-up study of 546 patients 14.5 years after RYGB. MethodsThey used a CGM for two 14-day periods, with a dietary intervention between periods. The Gastrointestinal Symptom Rating Scale (GSRS) and the Dumping Severity Score (DSS) questionnaires were completed at the start and end of the study. ResultsThe 22 women had preoperative age 39.6 ± 7.7 years and body mass index (BMI) 42.0 ± 4.0 kg/m2, present age 54.6 ± 7.7 years and BMI 29.8 ± 4.8 kg/m2. The total GSRS score and DSS of early dumping decreased after the diet intervention. The number of events with Level 1 (<3.9 mmol/L) or Level 2 (<3.0 mmol/L) hypoglycemia did not change in the second period. Half of the patients had fewer, three had unchanged, and eight had more frequent events with Level 1 hypoglycemia after the intervention. Ten patients had Level 2 hypoglycemia. ConclusionThough inconclusive findings, a personalized dietary intervention reduces GSRS. This intervention was accompanied by lower mean absolute glucose in patients with recurrent abdominal pain after bariatric surgery. However, further studies are needed to explore the benefits of CGM in this setting.

Improvement of dyspeptic symptoms after Helicobacter pylori eradication therapy in Japanese patients.

Helicobacter pylori eradication therapy effectively improves the abdominal symptoms and bowel habits of patients. Patients in whom dyspepsia is under control by 6 to 12 months after successful H. pylori eradication are defined as having H. pylori-associated dyspepsia, and patients with dyspepsia that is refractory to successful eradication are defined as having functional dyspepsia. Here, we aimed to investigate the association between H. pylori eradication and improvement of dyspepsia in the short and long term after eradication therapy. Dyspeptic symptoms before treatment and at 2 and 12 months after eradication were evaluated using the Gastrointestinal Symptom Rating Scale (GSRS) in 282 H. pylori-positive Japanese patients who underwent eradication therapy. Of the Japanese H. pylori-positive patients, 48.2% (136/282) had upper abdominal symptoms. Eradication improved dyspepsia in 34.5% (47/136) of the patients at 2 months post eradication, which continued to be under control up to 12 months. A significant decrease at 2 and 12 months after eradication, compared with before eradication, was observed in total GSRS (from 25.7 ± 10.4 [before eradication, n = 249] to 23.3 ± 7.2 [after 2 months, n = 249] and 24.8 ± 7.8 [after 12 months, n = 81]; P = 0.014 and 0.321, respectively), gastric pain score (from 4.1 ± 1.9 to 3.7 ± 1.3 and 3.7 ± 1.2; P = 0.025 and 0.047), and constipation score (from 5.9 ± 3.1 to 5.2 ± 2.3 and 5.9 ± 3.0; P < 0.021 and 0.862). H. pylori-positive dyspepsia patients should be recommended to undergo H. pylori eradication to alleviate dyspepsia-associated symptoms.

#4287 GASTROINTESTINAL SYMPTOMS IN PATIENTS RECEIVING HEMODIALYSIS: PREVALENCE, SEVERITY AND ASSOCIATED FACTORS

Abstract Background and Aims Gastrointestinal (GI) symptoms are common among patients with chronic renal failure, especially in those treated with maintenance hemodialysis (HD), and may adversely affect patients'' quality of life. A variety of GI symptoms has been reported, but previous studies present conflicting results regarding their association with age, sex, comorbidities, concomitant medications and dialysis modality. This study aimed to assess the prevalence and severity of GI symptoms in the maintenance HD population and explore possible associated factors. Method A total of 188 stable patients (55.3% male, 53.7% ≥65 years of age, age range 24–85, 30.9% with diabetes, 19.9% smokers) from three HD centres were enrolled in this observational cross-sectional study. Gastrointestinal symptoms were assessed by the self-administered Gastrointestinal Symptoms Rating Scale (GSRS). The scale includes 15 items graded by a 7-point Likert scale that can be grouped into five dimensions: abdominal pain syndrome, reflux syndrome, indigestion syndrome, diarrhoea syndrome, and constipation syndrome. A dimension score is calculated as the mean value of the items belonging to the specific syndrome, and the final score is the mean of dimension scores. Standard blood analyses, Kt/V, body mass index (BMI) and malnutrition-inflammation score (MIS) were determined in all patients. Other relevant demographic and clinical data were obtained from the patient's medical records. The results were analyzed with SPSS software, version 22 (IBM Corporation, New York, USA). Results The average BMI was 25.04±4.29. Half of the patients (50.3%) were overweight, 45.3% had normal weight, and 4.3% were underweight. The average MIS was 5.64±2.87. The average number of symptoms per patient was 4.01±3.20 (range 0 – 15). At least one GI symptom was reported by 84.6% of patients (33.0% reported 1 – 3 symptoms, and 49.5% reported 4 or more symptoms). The mean GSRS scores for eating dysfunctions were 1.59±1.08 for reflux, 1.74±0.98 for abdominal pain, 1.75±1.14 for constipation, 1.94±1.01 for indigestion, and 1.38±0.90 for diarrhoea. Total GSRS was 1.70±0.61. Elderly patients had a significantly lower overall number of GI symptoms (3.49±2.83 vs 4.57±3.51; p = 0.023), lower abdominal pain score (1.60±0.96 vs 1.91±1.09; p = 0.031), and indigestion score (1.74±0.85 vs 2.18±1.15; p = 0.005), but higher constipation (1.94±1.27 vs 1.54±0.96;p = 0.017) score than individuals under 65 years of age. Patients smoking cigarettes and those longer on HD had a significantly higher overall number of GI symptoms (3.44±0.56 vs 3.10±0.25; p = 0.035 and 3.78±2.99 vs 2.46±2.23; p = 0.016 respectively). Average abdominal pain score was significantly higher in non-diabetic (1.87±1.04 vs 1.44±0.75; p = 0.002) and underweight (2.62±1.51 vs 1.71±0.94 vs 1.65±0.90; p = 0.023) compared to diabetic, normal weight and overweight patients respectively. Patients taking ASA or NSAIDs had significantly higher total GSRS scores (1.84±0.72 vs 1.60±0.50; p = 0.016 and 1.88±0.64 vs 1.65±0.59; p = 0.044 respectively). Sex, dialysis adequacy and malnutrition-inflammation status were not significantly related to any of the GSRS dimensions. Conclusion The present study demonstrates a high prevalence of GI symptoms in maintenance HD patients and identifies age, cigarette smoking, diabetes, dialysis vintage, and certain medications as important elements to consider when addressing specific groups of GI symptoms in this population.

#5951 INFLUENCE OF DIETARY INTAKE ON GASTROINTESTINAL SYMPTOMS AND INFLAMMATION MARKERS IN PERITONEAL DIALYSIS PATIENTS IN SLOVENIA

Abstract Background and Aims Gastrointestinal symptoms are prevalent in patients with end-stage renal disease. Gastrointestinal symptoms in such patients are related to gastric hypomotility, increased medication intake, uremia, and changes in diet. In addition GI symptoms and problems associated with bowel dysfunction are a common cause of technique failure and poor dialysis efficacy. The reason for presence of some gastrointestinal symptoms is also chronic inflammatory state. Inflammation can have many negative effects, including decreased appetite, accelerated protein skeletal muscle breakdown and hypercatabolism. Method 14 peritoneal dialysis patients were included in single Department of Nephrology in the University Medical Center in Ljubljana. All patients were interviewed by a dietitian and nutritional assessment was conducted. Gastrointestinal symptom Rating Scale (GSRS) with 7-grade Likert scale was used to evaluate the intensity of GI symptoms and Bristol Stool Form Scale (BSFS) to classify patient's stool. The dietary intake of peritoneal dialysis patients was assessed using 7-day food diaries and analyzed with Prodi program (PRODI® 6.4 Expert program, Stuttgart, Deutschland). Body composition has been measured with bio impedance spectroscopy. Routine blood analysis was performed. Results Among 14 patients undergoing peritoneal dialysis, most of them were male (71.4%) with average age of 53.07 ± 12.32 years. Average energy intake of 14 patients was 21.05 ± 5.72 kcal/kg body weight per day, average protein intake was 0.87 ± 0.39 g/ kg body weight per day and average fiber intake was 13.75 ± 7.25 g per day. They were inadequate according to the dietary guidelines for peritoneal dialysis patients. Average dietary protein-fiber index was 6.86 ± 3.81 per day. Average PRAL value was 15.84 ± 13.44 for women and 6.52 ± 17.99 for men. Average dietary potassium intake was 1917.80 ± 790.08 mg per day which corresponds to the guidelines for peritoneal dialysis patients and average potassium serum value 4.45 ± 0.42 mmol/L. GSRS questionnaire showed peritoneal patients had minor to mild discomfort in abdominal pain, constipation and indigestion GI symptom cluster. Patients’ self-analysis of stool showed BSFS Types 3.23 ± 1.64 if BSFS Types 3–5 are defined as normal stools. Dietary protein intake strongly correlated with dietary energy intake (r = 0.76, p = 0.003), dietary protein-fiber index strongly correlated with PRAL value (r = 0.70, p = 0.007) and dietary potassium intake moderately to strongly correlated with dietary fiber intake (r = 0.62, p = 0.025). Serum value of IL-6 strongly correlated with dietary potassium intake (r = 0.72, p = 0.006) and moderately to strongly correlated with dietary fiber intake (r = 0.6, p = 0.034). The correlation between dietary potassium intake and serum hsCRP was significant (p = 0.042). The correlation between Bristol stool consistency value and serum hsCRP was significant (p = 0.0255). The correlation between total GSRS score and serum value of albumin was significant (p = 0.0010). The correlation between total GSRS score and dietary potassium intake was significant (p = 0.0015). The correlation between total GSRS score and dietary protein-fiber index was significant (p = 0.0403). Conclusion Gastrointestinal diseases in peritoneal dialysis patients are comparatively understudied in the literature, despite having a significant impact on dialysis efficacy and the quality of life. Analysis of GSRS questionnaire showed that abdominal pain, constipation and indigestion caused minor to mild discomfort in PD patients. The analysis also showed that fiber intake, potassium intake and gastrointestinal symptoms are significantly associated with inflammation markers and are important contributing factors to chronic inflammatory state in these patients. Patients still lack the basic knowledge of nutrition, thus in the future nutritional consultations, innovative teaching techniques and help will be crucial to prevent the decline in nutritional status.

Effects of Drinking Electrolyzed Alkaline-Reduced Water on Functional Dyspepsia: A Randomized, Double-Blind, Controlled Prospective Trial

A well-known functional gastrointestinal disorder called functional dyspepsia (FD) is defined by dyspeptic symptoms without any structural abnormalities. In alternative intervention, electrolyzed alkaline-reduced water (EARW) consumption is regarded as a treatment modality for gastrointestinal symptoms despite its mechanism not yet fully understood. The present clinical study aimed to investigate the effects of EARW on gastrointestinal symptoms of patients with FD. Forty-eight participants with FD were screened, and 42 were enrolled. Participants were randomly allocated to the EARW (n = 21) and purified water (PW) (n = 21) groups. The EARW group ingested EARW (10 mL/kg body weight/day) for 6 weeks. The gastrointestinal symptom rating scale (GSRS), functional dyspepsia-related quality of life (FD-QoL), the Korean version of the Nepean Dyspepsia Index (NDI-K) were used as primary outcome measures at baseline and at 6 weeks, and inflammatory markers were measured as the secondary outcome. Two participants dropped out, and 40 participants (EARW = 20 and PW = 20) completed the trial. Total GSRS score was significantly lower in the EARW group (34.27%, p &lt; 0.01) than in the PW (18.16%) group. In the five subcategories of GSRS, the decreased score between baseline and post-intervention for the EARW and PW groups were 43.59% and 21.33% in abdominal pain score, respectively; 38.98% and 18.92% in reflux syndrome, respectively; 25.42% and 20.90% in diarrhea, respectively; 35.87% and 21.48% in indigestion, respectively; and 32.81% and 10.71% in constipation, respectively, and all the parameters were significantly different in the EARW group compared with those in the PW group. The NDI-K score was also lower in the EARW group (p &lt; 0.01) than in the PW group. FD-QoL score decreased significantly more in the EARW group after intervention than in the PW group (p &lt; 0.05). Additionally, inflammatory cytokines (TNF-α and IFN-γ) levels significantly suppressed in the EARW group after 6 weeks of drinking compared with the levels at the baseline. Our clinical study suggests that long-term drinking of EARW (pH 9.5) may improve FD-related symptoms and the quality of life of FD patients through home-based administration.

Patient-reported prevalence of gastrointestinal issues in the adult skeletal dysplasia population with a concentration on osteogenesis imperfecta.

Patient-reported concerns indicate that gastrointestinal (GI) manifestations affect the skeletal dysplasia population, but quantitative information regarding prevalence and severity of GI issues is limited. We examined the frequency and characteristics of GI symptoms in adults with skeletal dysplasias by reviewing 101 responses to the Gastrointestinal Symptom Rating Scale (GSRS). Participant demographics, medication history, and ambulatory status were collected from medical records. Compared to published GSRS reference data, our cohort scored higher on reflux, diarrhea, and total scores, and lower on abdominal pain and indigestion scores; none of these differences were statistically significant. Although osteogenesis imperfecta respondents had more severe symptoms across all domains, only reflux reached significance (p=0.009). Scores in patients with achondroplasia were higher for indigestion, constipation, diarrhea, and total scores and lower on abdominal pain and reflux scores than the general population; only the diarrhea score was significant (p=0.034). There were no statistically significant differences in any of the domain or total GSRS scores across ambulatory status groups. Increased height correlated with worse abdominal pain domain score (p=0.033). The number of medications positively correlated with total GSRS score (p=0.013). Future studies should include larger numbers of individuals to allow a more in-depth analysis of patient-reported symptoms and signs within this population.

The effect of group-based education on gastrointestinal symptoms and quality of life in patients with celiac disease: randomized controlled clinical trial

BackgroundIn this trial, we investigated the effect of a group-based education program on gastrointestinal (GI) symptoms and quality of life (QOL) in patients with celiac disease (CD).MethodIn the present study, 130 patients with CD who were on a GFD for at least 3 months, randomly assigned to receive group-based education (n = 66) or routine education in the celiac clinic (n = 64) for 3 months. We assessed gastrointestinal symptoms and quality of life using the gastrointestinal symptom rating scale (GSRS) questionnaire and SF-36 questionnaire at baseline and 3 months after interventions.ResultsThe mean age of the participants was 37.57 ± 9.59 years. There were no significant differences between the two groups regarding the baseline values. Results showed that the mean score of total GSRS score in the intervention group was significantly lower compared with the control group 3 months post-intervention (p = 0.04). Also, there was a significant difference in the mean score of SF-36 between the two groups 3 months post-intervention (p = 0.02).ConclusionResults showed that group-based education was an effective intervention in patients with celiac disease to improve gastrointestinal symptoms and quality of life.Trial registration IRCT code: IRCT20080904001197N21; registration date: 5/23/2019.

Metformin Intolerance: A Proposal for Definition Using the GSRS

Metformin is a first line drug for the treatment of patients with type 2 diabetes mellitus (T2DM) and has been associated with metformin intolerance with disappointing patient adherence. Since there is no official definition for metformin intolerance, comparison of international study results on gastrointestinal complaints is almost impossible. In the present study with type 2 diabetes patients who are on a metformin immediate-release (MIR) and are visiting the outpatient’s department of internal medicine. To create a quantifiable and standardized definition of metformin intolerance, this study used the Gastro-intestinal Symptom Rating Scale (GSRS) to evaluate the gastrointestinal complaints. A total of 59 patients (mean age 62.56; +/- 12.08) completed the GSRS in an interview with a skilled investigator. The mean GSRS score for the study population was 34.56 (+/- 14.57). Subsequently two subpopulations were created using 50 as a cutoff point. This resulted in two populations with statistically significant different GSRS scores of 55.50 (+/- 7.88) for patients with a GSRS score of ≥ 50 versus 28.04 (+/- 8.86) for patients with a GSRS score of < 50. The total GSRS results for the various metformin dosages yielded comparable results (figure 1, p<0.05). The authors recommend the use of the GSRS in all studies on the topic of metformin intolerance to enable the comparison of results of international studies. In addition, the authors propose the use of a cutoff GSRS score of 50 as an international definition for metformin intolerance.

Effectiveness and safety of kamikihito, a traditional Japanese medicine, in managing anxiety among female patients with intractable chronic constipation

Background and purposeThe prevalence of anxiety in patients with chronic constipation is particularly high and these individuals are not necessarily satisfied by normal treatments targeting the gastrointestinal tract. Kamikihito, a traditional Japanese Kampo medicine, has been widely used to date in treating anxiety and neurosis in Japan. We conducted a single-arm, open-label pilot study of female patients with intractable chronic constipation and anxiety who took kamikihito by mouth for 12 weeks. Materials and methodsValidated symptom questionnaires on anxiety and gastrointestinal symptoms [the Profile of Mood States, second edition (POMS2); the State–Trait Anxiety Inventory (STAI); and the Gastrointestinal Symptom Rating Scale (GSRS)] were completed at each study visit. Plasma, salivary, and stool samples were also assessed to evaluate levels of clinical bioactive substances linked to stress and inflammation, oxidative levels, the metabolome profile, and gut microbiota. ResultsTwenty-four patients completed this study. Anxiety was significantly reduced at four and 12 weeks (Tension–Anxiety subscale of the POMS2, p = 0.006 and p = 0.039; Trait anxiety score of the STAI, p < 0.001 and p = 0.034), while the total GSRS score was improved at 12 weeks (p = 0.039). Targeted metabolomics in plasma showed significant alterations in some metabolites associated with psychological symptoms, such as O-phosphoethanolamine. No significant differences were found between pre- and posttreatment levels of clinical bioactive substances related to stress and inflammation, oxidative levels, and the gut microbiota in this cohort. No serious adverse events occurred. ConclusionKamikihito ameliorated psychological and gastrointestinal symptoms in patients with chronic constipation. In parallel with the onset of efficacy, kamikihito modulated some anxiety-related metabolites. Kamikihito was safe and well-tolerated.

Self-Reported Gastrointestinal Symptoms Two To Four Years After Bariatric Surgery. A Cross-Sectional Study Comparing Roux-en-Y Gastric Bypass and Laparoscopic Sleeve Gastrectomy

BackgroundRoux-en-Y gastric bypass (RYGBP) and laparoscopic sleeve gastrectomy (LSG) are efficient methods for weight loss (WL) and WL maintenance in severe obesity. However, the knowledge of gastrointestinal (GI) symptoms after surgery is limited. This study aimed to compare the severity of GI symptoms, pain, and self-rated health 2 to 4 years after RYGBP and LSG surgery.MethodsIn this cross-sectional study, RYGBP and LSG patients answered a questionnaire including the Gastrointestinal Symptom Rating Scale (GSRS), questions from the Brief Pain Inventory (BPI), and self-rated health (SRH).ResultsA total of 172/303 (57%) responded, RYGBP (n=73) and LSG (n=99). The mean age was 45.3 (SD 11.1) years (74% females). There was no evidence of a difference in total GSRS scores between the surgical methods (p=0.638). There were higher scores of reflux symptoms in LSG vs. RYGBP (both median 1, 75-percentile 2.5 vs. 1.0, p <0.001) and higher consumption of acid-reducing medication after LSG (32% vs. 12%, p <0.001). Pain scores were low in both groups; however, average abdominal pain was higher for RYGBP, median 2 (IQR 0–4) vs. median 1 (IQR 0–3) for LSG (p = 0.025). There was no significant difference in SRH.ConclusionsPatients undergoing RYGBP and LSG surgery reported similar total GSRS scores and low pain scores 2 to 4 years after surgery. However, reflux symptoms and use of acid-reducing medication occurred more frequently after LSG surgery, while abdominal pain was more frequent in RYGBP surgery. These findings are important for surgical decision-making and follow-up.Graphical abstract

Impact of Different Helicobacter pylori Eradication Therapies on Gastrointestinal Symptoms.

Background and Objectives: Helicobacter pylori (H. pylori) infection impairs quality of life. However, whether eradication therapy ameliorates gastrointestinal symptoms remains questionable. The main objective of this study was to evaluate the influence of H. pylori eradication therapy on gastrointestinal symptoms. Materials and Methods: A total of 140 patients, 59 women and 81 men, with a mean age of 61 and suffering from H. pylori infection in the University Hospital of Split, Croatia, were enrolled in the study. Patients were randomly assigned to either concomitant or hybrid therapies. The Gastrointestinal Symptom Rating Scale (GSRS) questionnaire was completed by patients prior to and after the eradication therapy. Results: In both groups, the total GSRS score improved significantly after therapy. In the concomitant group, the abdominal pain score, reflux symptoms score and indigestion score decreased significantly after therapy. In the group with hybrid therapy, all five groups of symptoms (abdominal pain, reflux symptoms, indigestion, diarrhea and constipation) significantly decreased after therapy. Patients with adverse events had significantly higher total GSRS scores after eradication therapy. Conclusions: H. pylori eradication therapy could alleviate gastrointestinal symptoms regardless of the treatment used, but the favorable effect seemed to be more pronounced after hybrid therapy.

Gastrointestinal Physiology Before and After Duodenal Switch with Comparisons to Unoperated Lean Controls: Novel Use of the SmartPill Wireless Motility Capsule

PurposeBariatric surgery alters gastrointestinal anatomy. In this exploratory study, the SmartPill® wireless motility capsule (WMC) was used to study changes in gastrointestinal physiology following biliopancreatic diversion with duodenal switch (BPD/DS).Material and MethodsTwenty-eight BPD/DS patients (35 ± 11 years, 50% females, body mass index [BMI] 56 ± 5) were to be examined preoperatively and postoperatively. In addition to transit time, appetite control and gastrointestinal symptoms were studied by patient-scored questionnaires (visual analogue scale and Gastrointestinal Symptom Rating Scale (GSRS)). Data was compared to 41 lean unoperated controls.ResultsAbout 1.8 years postoperatively, 18 patients (BMI 35.8 ± 8.3) returned for a second WMC test. As expected, small bowel transit time was reduced, from 3.9 ± 1.6 h to 2.8 ± 2.0, p = 0.02, and at both these time points, it was shorter than in lean controls (5.4 ± 1.9 h, p = 0.001). Postoperatively, a trend towards reduced colon and whole gut transit times was seen in BPD/DS-patients, thus approaching those of lean controls. Surprisingly, BPD/DS patients scored higher satiety than controls preoperatively as well as increased hunger and desire to eat postoperatively. Compared to lean, BPD/DS patients reported a higher total GSRS score at both time points (1.2 ± 0.2 vs 1.7 ± 0.6 and 2.3 ± 0.5, p < 0.001). Postoperatively, the scores for diarrhea and indigestion increased.ConclusionsThe novel use of the SmartPill system in BPD/DS patients gave the expected readouts. Although small bowel transit time was further shortened after BPD/DS, whole gut transit time did not differ from controls. Typical gastrointestinal symptoms were reported postoperatively.Graphical abstract

Association between gastrointestinal symptoms and depression among older adults in Taiwan: A cross-sectional study.

Older adults with depression more frequently experience somatic and gastrointestinal (GI) problems compared with people without depression and younger adults with depression. However, whether GI symptoms are predictive of elevated rates of depression among older adults is unclear. We enrolled 106 older adults (>60 years old); 69 had late-life depression (LLD), and 37 were controls. All participants gave ratings on the Gastrointestinal Symptom Rating Scale (GSRS) and Hamilton Depression Rating Scale. Food consumption was assessed using a food frequency questionnaire, and a Mediterranean diet score was used as a covariate. Compared with the controls, patients with LLD reported higher levels of depressive and GI symptoms and reported more reflux, abdominal pain, and dyspepsia symptoms, and these symptoms were correlated with Hamilton Depression Rating Scale scores (GSRS total: β = 0.47; reflux: β = 1.47; abdominal pain: β = 1.98; dyspepsia: β = 1.02; all p < 0.01). After demographic variables and Mediterranean diet score were controlled for, a logistic regression analysis indicated that total GSRS score was an independent determinant of LLD (odds ratio: 1.20, 95% CI: 1.04-1.38). Moreover, a stratified analysis by depression severity indicated that higher total GSRS score may contribute to greater depression severity (odds ratio: 1.25, 95% CI: 1.04-1.52). We provide evidence that GI symptoms are associated with depressive symptoms among patients with LLD. Older people with more specific GI symptoms, such as reflux, abdominal pain, and dyspepsia, are potentially at greater risk of having LLD.

Characterization of Gastrointestinal Symptom Type and Severity in Parkinson's Disease: A Case-Control Study in an Australian Cohort.

While constipation is a well-known non-motor symptom which may precede the onset of the classical motor symptoms of PD, there have been few comprehensive studies of gastrointestinal (GI) symptoms in people with PD (PwP). To investigate the spectrum of GI symptoms in an Australian PwP cohort and their relationship to use of anti-parkinsonian medications dietary habits and smoking. The prevalence and severity of GI symptoms were compared in a group of 163 PwP and 113 healthy control subjects using the Gastrointestinal Symptom Rating Scale (GSRS). Corrected linear regression models were used to determine differences between PwP and controls, and to investigate the influence of different classes of anti-Parkinsonian medications. PwP reported a greater frequency of constipation and GI-associated illnesses when compared to healthy controls. Total GSRS scores (P < 0.0001), upper GI symptoms (P < 0.0001), and hypoactive GI Symptoms (P < 0.0001) were all significantly greater in the PD cohort than controls. Further analyses revealed a positive association between the use of anti-Parkinsonian medications and total GSRS scores (P < 0.001), as well as upper GI symptoms (P < 0.001) and hypoactive GI function (P < 0.001). This study illustrates the frequency and array of GI symptoms in a large PD cohort. The findings indicate that anti-parkinsonian medications play an important role in the presentation and development of GI symptoms.

Comparison of a Novel Herbal Medicine and Omeprazole in the Treatment of Functional Dyspepsia: A Randomized Double-Blinded Clinical Trial.

Background The Trachyspermum ammi L. (TA), Anethum graveolens L. (AG), and Zataria multiflora Boiss (ZM) herbal oils are among the most used herbal products in traditional medicine as the antiseptic, anesthetic, carminative, and antispasmodic. However, there are no clinical studies to evaluate the efficacy of the herbs mentioned in the treatment of functional dyspepsia (FD). This study was designed to appraise the efficacy and safety of a novel herbal medicine consisting of ZM, AG, and TA essential oils compared to omeprazole in FD treatment. Methods The present study was a randomized double-blind clinical trial with parallel groups in Iran. Patients in control and intervention arms received omeprazole 20 mg once a day and 250 mg soft-gel capsules containing 180 mg of essential oils of ZM, AG, and TA twice a day for two weeks, respectively. The primary outcome was the sufficient response rate in the postprandial distress syndrome (PDS) and/or epigastric pain syndrome (EPS) at the end of the intervention. Secondary outcomes were the improvement rate in the PDS, EPS, Gastrointestinal Symptom Rating Scale (GSRS), and quality of life scores. Also, safety and tolerability were assessed. Results The within-group comparison of EPS, PDS, total GSRS, GSRS Pain, and GSRS Dyspepsia scores with that at the end of the treatment indicated a significant reduction in both control and intervention groups (p < 0.001). However, after two weeks of treatment, the herbal medication and omeprazole arms were significantly different in the sufficient response rate based on PDS (p < 0.01) and EPS (p < 0.05) scores (78.3% (18/23) and 73.7% (14/19) in the intervention group vs. 36.4% (8/22) and 40.9% (9/22) in the control group). Also, the mean reduction in EPS (p < 0.05), PDS (p < 0.01), and GSRS (p < 0.001) scores after treatment was significantly higher in the intervention group than control group. Conclusion Based on the study findings, this herbal medicine can be considered as an appropriate treatment of FD. However, a larger multicenter trial is needed to confirm the results of the trial.

Effect of acupoint application therapy at different timing points on gastrointestinal function recovery and heart rate variability after laparoscopic resection of colorectal cancer

To observe the effect of acupoint application therapy at different timing points on the gastrointestinal function recovery and heart rate variability (HRV) after laparoscopic resection of colorectal cancer under the instruction of enhanced recovery after surgery (ERAS). A total of 105 patients for the selective laparoscopic resection of colorectal cancer were selected and randomized into a preoperative acupoint application group (35 cases, 3 cases dropped off), a postoperative acupoint application group (35 cases, 1 case dropped out) and a control group (35 cases, 2 cases dropped off). In the control group, ERAS interventions were provided, such as health education, fluid supplementation and multi-mode analgesia. On the base of the treatment as the control group, in the preoperative acupoint application group and the postoperative acupoint application group, 3 days before operation and 6 h after operation, the acupoint application therapy was given respectively. The acupoints were Zusanli (ST 36), Shangjuxu (ST 37), Sanyinjiao (SP 6), Neiguan (PC 6) and Xiajuxu (ST 39). The acupoint application was exerted for 6 h each time, once daily till the first postoperative exhaust and defecation presented. It was to observe the time of the first postoperative exhaust, defecation and food intake, the score of visual analogue scale (VAS) 1 to 3 days after operation, the total score of gastrointestinal symptom rating scale (GSRS) before and 1 week after operation, as well as the related indicators of HRV [standard deviation of NN intervals (SDNN) and the ratio of low-frequency power and high frequency power (LF/HF)] in the three groups successively. Besides, the adverse reactions were recorded during intervention in the three groups. Compared with the control group, the time of the first postoperative exhaust and the time of the first postoperative defecation were all earlier in the preoperative acupoint application group and the postoperative acupoint application group respectively (P<0.05), and VAS scores 1 to 3 days after operation and total GSRS scores 1 week after operation were all reduced (P<0.05); the time of first food intake was earlier after operation (P<0.05), and SDNN and LF/LF were increased 1 day and 3 days after operation in the preoperative acupoint application group (P<0.05). Compared with the postoperative acupoint application group, in the preoperative acupoint application group, the time of the first postoperative exhaust and the time of the first postoperative defecation were all earlier (P<0.05), VAS scores were reduced in 1 to 3 days after operation (P<0.05), and SDNN 1 day and 3 days after operation and LF/HF 1 day after operation were all increased (P<0.05). No adverse reaction was detected in patients of the three groups. Under the instruction of ERAS, the preoperative acupoint application effectively promotes the postoperative gastrointestinal function recovery, improves HRV and autonomous nerve function in the patients after laparoscopic resection of colorectal cancer. The therapeutic effect of this therapy is better than the postoperative acupoint application.

The Effect of Complex Korean Medical Treatment with Acupotomy on Irritable Bowel Syndrome: A Case Report

The effects of complex Korean medicine treatment including acupotomy, on irritable bowel syndrome (IBS) are reported in this case study. A 54-year-old woman with diarrheal symptoms that alternatively improved and worsened for many years and worsening abdominal pain visited the emergency room and was diagnosed with IBS; she was admitted for approximately 2 weeks at the Acupuncture and Moxibustion Department of National Medical Center (NMC). Numerical rating scale (NRS), irritable bowel syndrome?quality of life (IBS-QOL), and gastrointestinal symptom rating scale (GSRS) scores were evaluated on the day of hospitalization, midway through the hospitalization period, and on the day of discharge. Abdominal pain was measured daily using NRS, and the score decreased from 8 at admission to 0 at discharge. The IBS-QOL percentile score improved from 42 points to 100 points. The total GSRS score also improved, from 30 points to 2 points. These results suggest that complex Korean medicine treatment with acupotomy, is useful for treating internal diseases, such as IBS, as well as musculoskeletal disorders.

The Efficacy and Safety of GCWB104 (Flos Lonicera Extract) in Functional Dyspepsia: A Single-Center, Randomized, Double-Blind, Placebo-Controlled Study.

Background/AimsThe Flos Lonicera extract GCWB104 has been shown to have significant protective effects against gastritis and gastric ulcers in vivo. The aim of this study was to investigate the efficacy and safety of GCWB104 in subjects with functional dyspepsia (FD).MethodsIn this single-center, double-blind, randomized clinical trial, 92 subjects diagnosed with FD using the Rome III criteria were allocated to either the test group (300 mg of GCWB104, containing 125 mg of Flos Lonicera extract, twice daily) or the placebo group (300 mg placebo, twice daily). The total score improvement on the Gastrointestinal Symptom Rating Scale (GSRS) for individual symptoms, changes in antioxidant levels, changes in dyspepsia-related quality of life according to the Nepean Dyspepsia Index (NDI), and adverse effects were compared before and after 8 weeks of treatment.ResultsThe differences in total GSRS scores and score improvements after 8 weeks of treatment were significant between the GCWB104 and control groups (p=0.0452 and p=0.0486, respectively). Thirteen of 15 individual symptoms on the GSRS improved in the GCWB104 group, while six symptoms improved in the control group. In addition, statistically significant changes in rumbling, loose stool, and stool urgency were observed in the GCWB104 group. Blood 8-hydroxy-2′-deoxyguanosine (8-OHdG) levels, known as antioxidants, showed significant reductions after 8 weeks of administration of GCWB104. There were no adverse events related to treatment with GCWB104.ConclusionsGCWB104 safely contributed to improvements in mild to moderate FD and irritable bowel syndrome symptoms. Antioxidant effects of GCWB104 were also suggested (Clinicaltrials.gov number NCT04008901).

Gastrointestinal symptoms before and after laparoscopic Roux-en-Y gastric bypass: a longitudinal assessment

BackgroundRoux-en-Y gastric bypass (RYGB) is an effective treatment for morbid obesity, but many patients have increased gastrointestinal symptoms. ObjectivesTo evaluate gastrointestinal symptoms and food intolerance before and after RYGB over time in a large cohort of morbidly obese patients. SettingA high-volume bariatric center of excellence. MethodsA prospective cohort study was performed in patients who underwent RYGB between September 2014 and July 2015, with 2-year follow-up. Consecutive patients screened for bariatric surgery answered the Gastrointestinal Symptom Rating Scale (GSRS) and a food intolerance questionnaire before RYGB and 2 years after surgery. The prevalence of gastrointestinal symptoms before and after surgery and the association between patient characteristics and postoperative gastrointestinal symptoms were assessed. ResultsFollow-up was 86.2% (n = 168) for patients undergoing primary RYGB and 93.3% (n = 28) for revisional RYGB. The total mean GSRS score increased from 1.69 to 2.31 after surgery (P < .001), as did 13 of 16 of the individual scores. Preoperative GSRS score is associated with postoperative symptom severity (B = .343, P < .001). Food intolerance was present in 16.1% of patients before primary RYGB, increasing to 69.6% after surgery (P < .001). Patients who underwent revisional RYGB had a symptom severity and prevalence of food intolerance comparable with that among patients with primary RYGB, even though they had more symptoms before revisional surgery. ConclusionsTwo years after surgery, patients who underwent primary RYGB have increased gastrointestinal symptoms and food intolerance compared with the preoperative state. It is important that clinicians are aware of this and inform patients before surgery.
