RESUMO
BACKGROUND: Examining the prevalence of irritable bowel syndrome (IBS) across regions has been challenging given significant methodological heterogeneity. AIMS: We aimed to perform a uniform assessment of the global burden of IBS using data from Google Trends, a novel, online tool. METHODS: Google Trends measures popularity of a search term in a given week compared to popularity of all search terms in that week, calculated as relative search volume (RSV). We compiled data on the popularity of IBS and its treatments across 173 countries between 2014 and 2018. We compared Google Trends popularity for IBS with prior epidemiological prevalence data, while controlling for gross domestic product (GDP) per capita and physician density. RESULTS: Of the 173 countries with Google Trends data, 137 countries also had data for GDP per capita and physician density. Worldwide popularity of IBS as a search topic increased from 79 to 89 (13% increase by RSV) over the 5-year period between 2014 and 2018. Country-specific change in IBS RSV ranged from - 35% (Nigeria) to + 64% (Pakistan). There was poor correlation between the Google Trends data and prior epidemiological data (0.08, Pearson correlation, p = 0.64). Popularity of the low-FODMAP diet increased the most among 8 common therapies (RSV 41 to 89, 117% increase). CONCLUSIONS: Google Trends is a novel tool that can complement traditional epidemiological methods in gastrointestinal disease. Future research is needed to assess its utility and accuracy as a measure of disease burden across different gastrointestinal diseases.

Background/Aims: Anxiety and depression are common comorbid psychiatric disorders in IBS patients, but the population-level determinants influencing these comorbidities in IBS patients are poorly understood. We sought to determine whether there was an association between comorbid affective disorders and socioeconomic status among irritable bowel syndrome (IBS) patients. Methods: We assembled a retrospective cohort of 1074 IBS patients with comorbid Generalized Anxiety Disorder (GAD) and/or Major Depressive Disorder (MDD) seen at two tertiary referral centers between 2007 and 2015. IBS patients with comorbid GAD and/or MDD were matched 3:1 by age, sex, and race to controls with IBS and no history of comorbid GAD and/or MDD. Socioeconomic status was approximated by patient zip codes. Results: IBS patients in the lowest socioeconomic group were more likely to be diagnosed with GAD and/or MDD compared to controls (OR = 1.38, p = .0004). The median average per capita income for comorbid GAD/MDD IBS patient cohort was also significantly lower than the control IBS patient cohort ($39,880.50 vs. $41,277.00, p = .02). Conclusions: Among IBS patients, the presence of comorbid Generalized Anxiety Disorder and/or Major Depressive Disorder is associated with lower socioeconomic status and lower average per capita income. These findings speak to a biopsychosocial model of illness, which should be considered by clinicians in the care of IBS patients.

Abdominal pain can be an important symptom in some patients with gastroparesis (Gp). AIMS: (1) To describe characteristics of abdominal pain in Gp; (2) describe Gp patients reporting abdominal pain. METHODS: Patients with idiopathic gastroparesis (IG) and diabetic gastroparesis (DG) were studied with gastric emptying scintigraphy, water load test, wireless motility capsule, and questionnaires assessing symptoms [Patient Assessment of Upper GI Symptoms (PAGI-SYM) including Gastroparesis Cardinal Symptom Index (GCSI)], quality of life (PAGI-QOL, SF-36), psychological state [Beck Depression Inventory (BDI), State-Trait Anxiety Index (STAI), PHQ-15 somatization scale]. RESULTS: In total, 346 Gp patients included 212 IG and 134 DG. Ninety percentage of Gp patients reported abdominal pain (89% DG and 91% IG). Pain was primarily in upper or central midline abdomen, described as cramping or sickening. Upper abdominal pain was severe or very severe on PAGI-SYM by 116/346 (34%) patients, more often by females than by males, but similarly in IG and DG. Increased upper abdominal pain severity was associated with increased severity of the nine GCSI symptoms, depression on BDI, anxiety on STAI, somatization on PHQ-15, the use of opiate medications, decreased SF-36 physical component, and PAGI-QOL, but not related to severity of delayed gastric emptying or water load ingestion. Using logistic regression, severe/very severe upper abdominal pain associated with increased GCSI scores, opiate medication use, and PHQ-15 somatic symptom scores. CONCLUSIONS: Abdominal pain is common in patients with Gp, both IG and DG. Severe/very severe upper abdominal pain occurred in 34% of Gp patients and associated with other Gp symptoms, somatization, and opiate medication use. ClinicalTrials.gov Identifier: NCT01696747.

AIM: To determine effect of irritable bowel syndrome (IBS) subtype on IBS-specific quality of life (QOL) questionnaire and its subscales. METHODS: We studied IBS patients visiting our functional gastroenterology disorder clinic at a tertiary care center of Unites States. IBS and IBS subtype were diagnosed using Rome-III questionnaire. QOL was assessed using IBS-QOL questionnaire. IBS-QOL assesses quality of life along eight subscales: dysphoria, interference with activities, body image, health worry, food avoidance, social reactions, sexual health, and effect on relationships. IBS-QOL and its subscales were both scored on a range of 0-100 with higher scores suggestive of better QOL. Results of overall IBS-QOL scores and subscale scores are expressed as means with 95%CI. We compared mean IBS-QOL score and its subscales among various IBS-subtypes. Analysis of variance (ANOVA) was used to compare the mean difference between more than two groups after controlling for age and gender. A post-hoc analysis using Bonferroni correction was used only when P value for ANOVA was less than 0.05. RESULTS: Of 542 patients screened, 243 had IBS as per Rome-III criteria. IBS-mixed (IBS-M) was the most common IBS subtype (121 patients, 49.8%) followed by IBS- diarrhea (IBS-D) (56 patients, 23.1%), IBS-constipation (IBS-C) (54 patients, 22.2%) and IBS-unspecified (IBS-U) (12 patients, 4.9%). Overall IBS-QOL scores were significantly different among various IBS-subtypes (P = 0.01). IBS-QOL of patients with IBS-D (61.6, 95%CI: 54.0-69.1) and IBS-M (63.0, 95%CI: 58.1-68.0) was significantly lower than patients with IBS-C (74.5, 95%CI: 66.9-82.1) (P = 0.03 and 0.02 respectively). IBS-D patients scored significantly lower than IBS-C on food avoidance (45.0, 95%CI: 34.8-55.2 vs 61.1, 95%CI: 50.8-71.3, P = 0.04) and interference with activity (59.6, 95%CI: 51.4-67.7 vs 82.3, 95%CI: 74.1-90.6, P < 0.001). IBS-M patients had more interference in their activities (61.6, 95%CI: 56.3-66.9 vs 82.3, 95%CI: 74.1-90.6, P = 0.001) and greater impact on their relationships (73.3, 95%CI: 68.4-78.2 vs 84.7, 95%CI: 77.2-92.2, P = 0.02) than IBS-C patients. Patients with IBS-M also scored significantly lower than IBS-C on food avoidance (47.2, 95%CI: 40.7-53.7 vs 61.1, 95%CI: 50.8-71.3, P = 0.04) and social reaction (66.1, 95%CI: 61.1-71.1 vs 80.0, 95%CI: 72.1-87.7, P = 0.005). CONCLUSION: IBS-D and IBS-M patients have lower IBS-QOL than IBS-C patients. Clinicians should recognize food avoidance, effects on daily activities and relationship problems in these patients.
