Worldwide Prevalence and Description of Cyclic Vomiting Syndrome According to the Results of the Rome Foundation Global Epidemiology Study.

INTRODUCTION: Cyclic vomiting syndrome (CVS) is a disorder of gut-brain interaction of unknown origin. The aim of this study was to evaluate the global prevalence of this disorder and its associated factors. METHODS: Data were collected from nationwide Internet surveys in 26 countries, with subjects evenly distributed by age, sex, and country. The survey included the Rome IV questionnaire and an extensive supplemental questionnaire to evaluate additional factors. RESULTS: A total of 54,127 participants completed the questionnaire (51% male, mean age 44.3 years). The pooled prevalence of CVS was 0.3% (95% confidence interval [CI] 0.3%-0.4%; n = 187), highest in Brazil (1%, 95% CI 0.6-1.5), and lowest in Japan and Germany (with no subject who fulfilled the criteria for CVS). The mean age of participants with CVS was 36.7 years (SD 13.5), and it was more common in women (56.7% vs 43.5%). Factors independently associated with this syndrome were female sex (odds ratio [OR] 1.52, 95% CI 1.13-2.03), young age (OR 2.57, 95% CI 1.34-4.94, for people between the ages of 18 and 39 years, compared with those older than 65 years), depression (OR 3.14, 95% CI 2.05-4.82, P < 0.001), and anxiety (OR 1.79, 95% CI 1.15-2.78, P < 0.001). Individuals with CVS had impaired quality of life (QoL) (Patient-Reported Outcomes Measurement and Information System 10-item score: physical QoL mean, 12.9 vs 15.5, P < 0.001; mental QoL mean 12.3 vs 14.4, P < 0.001) compared with others. DISCUSSION: CVS is a relatively common disorder that has a negative impact on QoL. It is important to raise awareness on this syndrome to avoid underdiagnosis and improve clinical practice.

Cardiovascular risk assessment in inflammatory bowel disease with metabolic dysfunction-associated steatotic liver disease.

BACKGROUND AND AIMS: Inflammatory bowel disease (IBD) has been reported to increase the risk of early atherosclerosis even in young patients. Moreover, metabolic dysfunction-associated steatotic liver disease (MASLD), which has been linked to IBD, is a well-recognized but underdiagnosis entity related to cardiovascular risk. We analyze the impact of MASLD in IBD patients' cardiovascular risk through both advanced lipoprotein profile sorted by nuclear magnetic resonance spectroscopy, and carotid artery intima-media thickness (CIMT). METHODS: Cross-sectional cohort study which involves 941 IBD adult outpatients. Of them, 50 patients with IBD who met criteria for MASLD and 50 with IBD without MASLD, matched by sex and age were included. Alterations in CIMT were evaluated considering abnormal measures above the 75th percentile adjusted for sex and age. Specific advanced lipoprotein profile was also carried out. RESULTS: Most of the patients had an abnormal CIMT (58%). MASLD (OR=5.05, CI 95%=1.71-14.92) and female sex (OR=3.32, CI 95%=1.03-10) were significantly associated with CIMT alterations. Dense LDL particles (with high cholesterol composition in general cohort (OR=3.62, 95% CI=1.07-12.19) and high triglycerides density in young subgroup (OR=6.25, 95% CI=1.04-50) but not total LDL cholesterol were associated with CIMT alterations. CONCLUSIONS: MASLD and female sex are associated with early atherosclerosis in IBD patients. Dense LDL particle in combination with vascular imaging findings should be evaluated as non-invasive tools in the management of cardiovascular risk in IBD patients.

Prevalence and description of disorders of gut-brain interaction in Spain according to the results of the Rome Foundation Global Epidemiology Study.

BACKGROUND: Data for Spain from the Rome Foundation Global Epidemiology Study on the disorders of gut-brain interaction (DGBI) were used to assess the national and regional prevalence of all 22 DGBI, the percentage of respondents meeting diagnostic criteria for at least one DGBI, and the impact on burden of disease in our country. METHODS: Data were collected through an anonymous, nationwide, and secure Internet survey with multiple built-in quality-assurance techniques that included the Rome IV diagnostic questionnaire and an in-depth supplemental questionnaire. KEY RESULTS: The survey was completed by 2072 adult Spanish participants (50.2% female) with a mean age of 45.67 ± 15.44 years with a good representative national distribution. 43.6% (41.5%-45.8%) met diagnostic criteria for at least one DGBI, with 8.2% for any esophageal disorder, 12.1% for any gastroduodenal disorder, 30.1% for any bowel disorder, and 11.5% for any anorectal disorder. Functional constipation was the most prevalent DGBI in Spain (12.8%). We found that proctalgia fugax (9.3%), unspecified bowel disorders (10.8%), and functional dysphagia (5.6%) showed unexplained high rates in our country. DGBI rates were higher for women. Having any DGBI was negatively associated with psychosocial variables (including quality of life, somatization, and concern about digestive problems), and associated with increased healthcare utilization. CONCLUSIONS & INFERENCES: We provide the first comprehensive data on the prevalence and burden of all DGBI in Spain using the Rome IV criteria. The enormous burden of DGBI in Spain highlights the need for specialized training and future research.
