ABSTRACT: Objective
The objective of this study is to evaluate irritable bowel syndrome (IBS) as a risk factor for osteoporosis and osteoporotic fracture in Korean women after controlling for basic confounding factors and considering detailed demographic and clinical information.Subjects and methods
We performed a nationwide population-based retrospective cohort analysis and matched every IBS case with a non-IBS case at a 1:4 frequency ratio based on age. The population consisted of female patients with data in the Health Insurance Review and Assessment (HIRA) database from 2002 to 2010. To determine the risk of osteoporosis and osteoporotic fracture in IBS and non-IBS patients, hazard ratios (HRs) with 95% confidence intervals (CI) were estimated using Cox proportional hazards regression models, adjusting for confounding variables, such as the area of residence, health insurance type, and economic status.Results
We identified 1,017,468 patients in the HIRA database with data from 2002 to 2010 who could potentially be included in the cohort. Among these, we identified 1,545 (11.4%) women (age >19 years) with newly diagnosed IBS (IBS group). Additionally, 6,180 patients without IBS and age-matched to the IBS group were selected. Cox modeling revealed that the crude HRs for osteoporosis and osteoporotic fractures in patients with IBS were 1.476 (95% CI, 1.241-1.754) and 1.427 (95% CI, 1.086-1.876), respectively.Conclusion
Our data showed an increased incidence of osteoporosis and osteoporotic fractures in women with IBS compared with age-matched controls.

Project description:BackgroundAlthough irritable bowel syndrome (IBS) is more common in women, little is known about the role of hormonal changes and menopause in IBS. This study aimed to evaluate for differences in gastrointestinal (GI) and psychological symptoms between pre- and postmenopausal women with IBS compared to age-matched men with IBS.MethodsPatients with Rome-positive IBS were identified. Premenopausal women were <45 years of age with regular menses. Postmenopausal women were ≥45 years without menses for at least 1 year. Younger men were <45 years, and older men were ≥45 years. Questionnaires measured severity of IBS symptoms, somatic symptoms, health-related quality of life (HRQOL), and psychological symptoms. Multivariable linear or logistic regressions evaluating relationships between age and sex were performed.Key results190 premenopausal women (mean age 30.25 years), 52 postmenopausal women (mean age 54.38 years), 190 men <45 years (mean age 30.45 years), and 52 men ≥45 years (mean age 53.37 years) were included. Postmenopausal IBS women had greater severity of IBS symptoms (P = .003) and worse physical HRQOL (P = .048) compared to premenopausal women. No differences were observed between age-matched older and younger IBS men. Constipation increased with age for both sexes but was the principal IBS subtype in women only.Conclusions and inferencesPostmenopausal women with IBS have more severe IBS symptoms than premenopausal women, while no comparable age-related changes were seen in IBS men. The modulatory effect of female sex hormones on brain-gut interactions which affect visceral perception and GI function likely contributes to these findings.

Project description:ObjectiveIrritable bowel syndrome (IBS) is a chronic pain disorder characterized by disturbed interactions between the gut and the brain with depression as a common comorbidity. In both IBS and depression, structural brain alterations of the insular cortices, key structures for pain processing and interoception, have been demonstrated but the specificity of these findings remains unclear. We compared the gray matter volume (GMV) of insular cortex (IC) subregions in IBS women and healthy controls (HC) and examined relations to gastrointestinal (GI) symptoms and glutamate + glutamine (Glx) concentrations. We further analyzed GMV of IC subregions in women with major depression (MDD) compared to HC and addressed possible differences between depression, IBS, IBS with depression and HC.DesignWomen with IBS (n = 75), MDD (n = 41) and their respective HC (n = 39 and n = 43) underwent structural brain MRI. IC subregion volumes were estimated using statistical parametric mapping software. General linear model approaches were applied to IC volumetric data and FDR-corrected partial correlation analyses assessed relations between GMV, GI symptoms and Glx concentrations.ResultsIBS patients had significantly smaller IC subregions than HC in both hemispheres but there was no significant difference between MDD compared with IBS and HC for any insular subregion. In IBS, the dorsal anterior insular volumes were negatively correlated with symptoms of nausea and pain, and the left ventral subregion showed a positive correlation with straining to defecate, while the posterior subregion volumes showed no relation to symptoms. In the anterior insula, concentration of Glx showed positive correlations with GMV bilaterally in HC and with GMV of the right anterior insula in IBS.ConclusionAs the interoceptive cortex, the insula shows substantial and disease-specific structural differences in patients with chronic interoceptive visceral pain. Particularly changes in the anterior proportions might be related to chronic exposure to or enhanced salience towards adverse interoceptive visceral signals and could be linked to biochemical changes, calling for further multimodal and longitudinal work.

Project description:INTRODUCTION:Cholecystokinin (CCK) belongs to a group of endogenous molecules known as brain-gut neuropeptides and functions as a neuropeptide as well as a gut hormone. It remains unclear whether genetic variation of the CCK receptor plays a role in irritable bowel syndrome (IBS). The aim of this study was to determine and compare the allele and genotype frequencies of the CCK(1) receptor polymorphisms between healthy controls and patients with IBS. METHODS:Genotyping of 80 patients with IBS (who met the Rome III criteria) and 76 healthy controls was performed. We performed PCR amplification for the CCK(1) receptor intron 1 779 T > C and Exon 1 G > A. We confirmed polymorphisms by direct sequencing method. RESULTS:There was a significantly different trend for genotypic distributions of the CCK(1) receptor polymorphism between patients with IBS and healthy controls (p for trend = 0.048). The CCK(1) receptor intron 1 779 T >C polymorphic type was more common in patients with 'IBS-constipation predominant (IBS-C) and IBS-mixed (IBS-M) forms' (19/31, 61.3%) than healthy controls 32/76, 42.1% adjusted odd ratio 2.43, 95% Confidence interval 1.01-5.86). The genotypic distributions of the CCK(1) receptor exon 1 polymorphism were not significantly different between the two groups (p for trend = 0.223). CONCLUSIONS:CCK(1) receptor polymorphisms were associated with IBS. In particular, the CCK(1) receptor intron 1 779 T > C polymorphic type was associated with 'IBS-C and IBS-M'. Further studies are needed in larger number of patients with an even distribution of IBS subtypes.

Project description:Introduction:Sleep disorder in adolescents is a problem that is rarely considered by both parents and healthcare professionals. Ignorance of sleep disorders is likely caused by the very rare occurrence of associated sporadic or emergency cases. Irritable bowel syndrome (IBS) is a functional gastrointestinal disorder characterized by abdominal pain and changes in the defecation pattern. Previous research has demonstrated IBS as one of the many causes of sleep disorders. Difficulty sleeping, frequent awakening, and difficulty returning to sleep after awakening are the symptoms often experienced by adolescents with IBS. The high incidence of IBS in adolescents and the large proportion of sleep disorders in IBS affect the quality of life and disrupt physical development, behaviour, and learning achievement. The relationship between IBS and sleep disorders in adolescents needs to be studied. This study aims to determine the relationship between sleep disorders and IBS in high school adolescents in Palembang. Methods:This is a cross-sectional study conducted on 294 high school adolescents in Palembang in June 2018. Random sampling method was used and the presence of IBS and sleep disturbances were assessed using a questionnaire. Results:Among all subjects, we found 113 subjects (38.4%) with IBS. Of these 113 subjects with IBS, only 60 subjects (53.1%) experienced sleep disorders. Conclusion:No correlation found between sleep disorders and IBS in adolescents.

Project description:ObjectiveThe relationship between daily meal and snack frequency with irritable bowel syndrome (IBS) was less investigated in the literature. We aimed to evaluate this association with IBS symptoms.DesignA cross-sectional study.SettingThis investigation was performed in Isfahan, a large province in the centre of Iran. Individuals were asked to complete a self-administered questionnaire to quantify the numbers of daily main meals (one, two or three), snacks (never, 1-2, 3-5 or >5) and the total of them (<3, 3-5, 6-7 or ≥8). IBS and its subtypes were diagnosed according to Rome Ш criteria.ParticipantsGeneral adults (n 4669, 2063 men and 2606 women).ResultsThe prevalence of IBS was 18·6 % in males and 24·1 % in females. Individuals consuming three main meals had 30 % decreased risk of IBS (OR 0·70, 95 % CI 0·52, 0·94) compared with those with one main meal in the crude model. After adjustments for all potential confounders this relation disappeared (OR 0·67, 95 % CI 0·43, 1·03). Gender-specified analysis revealed that women consuming three main meals per day had 32 % decreased likelihood of having IBS symptoms compared with one daily main meal takers (OR 0·68, 95 % CI 0·47, 0·99). This relation remained significant after adjustment for potential confounders (OR 0·56, 95 % CI 0·36, 0·89). A decreased likelihood of IBS in the highest category of main meal consumption compared with the lowest one was found in obese or overweight subjects (OR 0·54, 95 % CI 0·32, 0·91), after adjustment for all confounders.ConclusionsOur findings suggested that there was no significant relation between main meal or snack frequency and IBS in Iranian adults, but a small inverse association was found among females and overweight/obese individuals in subgroup analysis. Further prospective studies are needed confirming these associations.

Project description:BackgroundPathophysiology of IBS is not well recognized; however, several studies have shown the possible relationship between diet and risk of IBS. We assessed the ability of the dietary inflammatory index (DII) to predict the risk of IBS.MethodsThe subjects were 155 IBS cases and 310 age- and sex-matched healthy controls (aged ≥18 years). The participants were recruited from June, 2019 to March, 2020. IBS was recognized using the Rome IV criteria. DII score was computed based on dietary intake using a 168-item FFQ. The DII score was calculated based on energy-adjusted amounts of nutrients using residual method. Logistic regression models were used to estimate multivariable odds ratios (ORs).ResultsThe mean DII score was significantly higher among IBS patients in comparison to healthy controls (0.78 ± 2.22 vs. - 0.39 ± 2.27). In crude model, increase in DII as continuous variable was associated with a significant increase in the risk of IBS (OR (95% CI): 1.26 (1.1-15.38)). Furthermore, the association remained significant even after adjusting for age and sex (OR (95% CI): 1.28 (1.1-17.41)) and after multivariate adjustment (OR (95% CI): 1.38 (1.2-1.56)). In crude, age and sex adjusted and multivariate-adjusted models subjects in fourth quartile of DII had higher OR in comparison to subjects in first quartile.ConclusionsThis study showed a possible positive association between a pro-inflammatory diet and the risk of IBS. Thus, encouraging intake of more anti-inflammatory dietary factors and reducing intake of pro-inflammatory factors may be a strategy for reducing risk of IBS.

Project description:Background: Parkinson's disease (PD) and irritable bowel syndrome (IBS) are respectively one of the most common neurodegenerative diseases and functional bowel diseases in the world. Recent studies suggest that patients with IBS seem to have a higher risk of PD, which conflicts with the result of previous meta-analysis. Therefore, the purpose of this systematic review is to evaluate all available evidence, in order to clarify the association between PD and IBS. Methods: Two reviewers independently searched the PubMed, Embase, Web of Science, and Cochrane library on April 25, 2021 to identify all records that explore the association between IBS and PD. All reports that clearly define PD and IBS and analyze the relationship between the two were included. The Newcastle-Ottawa scale was used to assess the risk of bias of included studies. Results: Five studies from four articles involving 2,044,110 subjects were included in this analysis. The pooled results demonstrated a significant association between PD and IBS (1.48; 95% CI: 1.35-1.62, P < 0.001), with subtle heterogeneity (I 2 = 0.0%, p = 0.585). The association was observed across genders and increased with age. However, the available evidence cannot allow a reliable analysis of the causal relationship between IBS and PD. Conclusion: This study demonstrates a higher risk of PD among subjects with IBS. Future studies are required to further clarify the causation and underlying mechanism of the association.

Project description:Fatigue is the most common extraintestinal symptom in women with irritable bowel syndrome (IBS). Genetic polymorphisms of monoamines are associated with fatigue in many chronic diseases. In this pilot exploratory study, the primary aim was to determine whether genetic polymorphisms of tryptophan hydroxylase ( TPH1/TPH2), serotonin reuptake transporter ( SERT), or catechol-O-methyltransferase ( COMT) are associated with fatigue in women with IBS. Additionally, analysis explored whether these genetic associations with fatigue would be present when controlling for abdominal pain, psychological distress, feeling stressed, and sleepiness during the day. Secondary analysis of two randomized controlled trial baseline data sets in Caucasian women with IBS ( N = 185) was conducted. Participants kept a daily diary with one dimension (i.e., severity) for each of the 26 symptoms, including fatigue, for 28 days prior to randomization. DNA samples were tested for single-nucleotide polymorphisms (SNPs) of TPH1 (four SNPs) /TPH2 (one SNP), SERT (one SNP), and COMT (one SNP). Analysis of covariance was used to examine associations of percentage of diary days with moderate to very severe symptoms with genetic polymorphisms. Only one SNP, TPH2 rs4570625, was significantly associated with fatigue ( p = .005). T-allele (low functional) carriers of TPH2 (i.e., G/T or T/T genotypes) reported a greater percentage of days with moderate to very severe fatigue than G/G homozygotes ( p = .001). Reduced synthesis of tryptophan in the central nervous system may contribute to reports of fatigue in women with IBS. Understanding genetic risk factors for fatigue may elucidate preemptive strategies to reduce fatigue in individuals with IBS.

Project description:Background and aimsSerotonin (5-hydroxtryptamine, 5-HT) is an important factor in gut function, playing key roles in intestinal peristalsis and secretion, and in sensory signalling in the brain-gut axis. Removal from its sites of action is mediated by a specific protein called the serotonin reuptake transporter (SERT or 5-HTT). Polymorphisms in the promoter region of the SERT gene have effects on transcriptional activity, resulting in altered 5-HT reuptake efficiency. It has been speculated that such functional polymorphisms may underlie disturbance in gut function in individuals suffering with disorders such as irritable bowel syndrome (IBS). The aim of this study was to assess the potential association between SERT polymorphisms and the diarrhoea predominant IBS (dIBS) phenotype.SubjectsA total of 194 North American Caucasian female dIBS patients and 448 female Caucasian controls were subjected to genotyping.MethodsLeucocyte DNA of all subjects was analysed by polymerase chain reaction based technologies for nine SERT polymorphisms, including the insertion/deletion polymorphism in the promoter (SERT-P) and the variable tandem repeat in intron 2. Statistical analysis was performed to assess association of any SERT polymorphism allele with the dIBS phenotype.ResultsA strong genotypic association was observed between the SERT-P deletion/deletion genotype and the dIBS phenotype (p = 3.07x10(-5); n = 194). None of the other polymorphisms analysed was significantly associated with the presence of disease.ConclusionsSignificant association was observed between dIBS and the SERT-P deletion/deletion genotype, suggesting that the serotonin transporter is a potential candidate gene for dIBS in women.

Project description:Background and aimIrritable bowel syndrome (IBS), eating disorders (ED) and endometriosis share common pathophysiological mechanisms, involving alterations of the gut-brain axis. The aim of the ENDONUT pilot study was to investigate an association between these three diseases by screening for IBS and ED in patients with endometriosis.MethodWe included patients from the CIRENDO cohort (Inter-Regional North-West Cohort of women with ENDOmetriosis) with a recent documented diagnosis of endometriosis of less than 4 years, regardless of age, date of onset of symptoms, type of endometriosis (digestive or not), with or without endometriosis-related digestive surgery. Validated questionnaires were used to screen for IBS (Rome IV, Francis score), ED (SCOFF-F, EAT-26), and anxiety/depression (HAD). Anthropometric data and lifestyle habits were also collected. The primary composite endpoint was SCOFF-F and ROME-IV scores.ResultsAmong 100 patients meeting inclusion criteria, 54 patients completed all the questionnaires. Of these, 19 had a positive SCOFF-F score (35.2%), 26 had a positive ROME-IV score (48.1%), and 14 patients (25.9%) had both a positive SCOFF-F score and a positive ROME-IV score (p = 0.006). Patients with positive SCOFF-F and ROME-IV scores had significantly higher HAD-anxiety and depression scores (p < 0.05).ConclusionThese results suggest a significant association between IBS, ED and endometriosis. The prevalence of IBS and ED in our population is higher than in the general population. Larger studies are needed to confirm these results, to better understand this triad, and to improve the diagnostic and multidisciplinary therapeutic management of these patients.
