Demographics and health care seeking behavior of Singaporean women with chronic constipation: implications for therapeutic management

Kok Ann Gwee1,2, Sajita Setia31Gleneagles Hospital, 2Yong Loo Lin School of Medicine, National University of Singapore (NUS), 3Janssen, Johnson and Johnson Pte Ltd, SingaporeIntroduction: Chronic constipation is significantly more prevalent in women than men in Singapore. We carried out a survey to study patient demographics, symptom prevalence, healthcare-seeking behavior, and patient satisfaction with available treatment options in women with chronic constipation.Methods: Responses were collected predominantly via a web-based survey from a panel representative of Singapore's women population. Eligibility was established using a nine-question screener.Results: A total of 1006 invited females took part in an online screener survey, of which 911 respondents did not meet the eligibility requirements for the chronic constipation survey. Of the total panelists consenting to participate (via both online and face-to-face interviews), 100 women met eligibility requirements and took the 22-question survey. Eligible respondents were skewed to younger patients but well mixed in terms of marital status. The majority of them were not keen on doing exercise and were working women, especially white collar females. The majority complained of straining and hard stools as the most common constipation symptoms (88% and 80% respectively) and rated constipation symptoms as severe or moderate. On average, respondents experienced constipation symptoms for 6 to 7 months in the last year. In more than two-thirds of respondents, constipation symptoms were frequent (at least 1 in 3 times). Most of the patients had attempted to treat constipation themselves and 80% had tried laxatives before visiting the doctor. Satisfaction with fiber supplements and laxatives was average and many of the users were not satisfied with their effect. Ineffectiveness and prolonged time taken for the treatment to take effect were the most common reasons for dissatisfaction. Nearly all respondents (97%) were interested in considering alternative prescriptive medication that is proven more effective.Conclusion: Chronic constipation symptoms in women are often severe and bothersome, and many patients are dissatisfied with available treatment options primarily because of lack of efficacy.Keywords: chronic constipation, demographics, health-care, laxative

The Gut Microbiota and Irritable Bowel Syndrome: Friend or Foe?

Progress in the understanding of the pathophysiology of irritable bowel syndrome (IBS), once thought to be a purely psychosomatic disease, has advanced considerably and low-grade inflammation and changes in the gut microbiota now feature as potentially important. The human gut harbours a huge microbial ecosystem, which is equipped to perform a variety of functions such as digestion of food, metabolism of drugs, detoxification of toxic compounds, production of essential vitamins, prevention of attachment of pathogenic bacteria to the gut wall, and maintenance of homeostasis in the gastrointestinal tract. A subset of patients with IBS may have a quantitative increase in bacteria in the small bowel (small intestinal bacterial overgrowth). Qualitative changes in gut microbiota have also been associated with IBS. Targeting the gut microbiota using probiotics and antibiotics has emerged as a potentially effective approach to the treatment of this, hitherto enigmatic, functional bowel disorder. The gut microbiota in health, quantitative and qualitative microbiota changes, and therapeutic manipulations targeting the microbiota in patients with IBS are reviewed in this paper

Translation and Validation of Enhanced Asian Rome III Questionnaires in Bengali Language for Diagnosis of Functional Gastrointestinal Disorders

Background/AimsFunctional gastrointestinal disorders (FGIDs), diagnosed by symptom-based criteria due to lack of biomarkers, need translated-validated questionnaires in different languages. As Bengali, the mother tongue of Bangladesh and eastern India, is the seventh most spoken language in the world, we translated and validated the Enhanced Asian Rome III questionnaire (EAR3Q) in this language.MethodsThe EAR3Q was translated in Bengali as per guideline from the Rome Foundation. The translated questionnaire was validated prospectively on Bengali-speaking healthy subjects (HS, n = 30), and patients with functional dyspepsia (FD, n = 35), irritable bowel syndrome (IBS, n = 40) and functional constipation (FC, n = 12) diagnosed by clinicians using the Rome III criteria. The subjects were asked to fill-in the questionnaire again after 2 weeks, to check for its reproducibility.ResultsDuring translation, the original and the backward translated English versions of the questionnaire demonstrated high concordance. Sensitivity of the Bengali questionnaire to diagnose patients with FD, IBS, FC, and HS was 100%, 100%, 75%, and 100%, respectively, considering diagnosis by the clinicians as the gold standard. On test-retest reliability analysis, Kappa values for FD, IBS, FC, and HS were 1.0, 1.0, 0.83, and 1.0, respectively. The Bengali questionnaire detected considerable overlap of FD symptoms among patients with IBS, IBS among patients with FD, and FD among patients with FC, which were not detected by the clinicians.ConclusionsWe successfully translated and validated the EAR3Q in Bengali. We believe that this translated questionnaire will be useful for clinical evaluation and research on FGIDs in the Bengali-speaking population

Development, Translation and Validation of Enhanced Asian Rome III Questionnaires for Diagnosis of Functional Bowel Diseases in Major Asian Languages: A Rome Foundation-Asian Neurogastroenterology and Motility Association Working Team Report

Background/AimsThe development-processes by regional socio-cultural adaptation of an Enhanced Asian Rome III questionnaire (EAR3Q), a cultural adaptation of the Rome III diagnostic questionnaire (R3DQ), and its translation-validation in Asian languages are presented. As English is not the first language for most Asians, translation-validation of EAR3Q is essential. Hence, we aimed to culturally adapt the R3DQ to develop EAR3Q and linguistically validate it to show that the EAR3Q is able to allocate diagnosis according to Rome III criteria.MethodsAfter EAR3Q was developed by Asian experts by consensus, it was translated into Chinese, Hindi-Telugu, Indonesian, Korean, and Thai, following Rome Foundation guidelines; these were then validated on native subjects (healthy [n = 60], and patients with irritable bowel syndrome [n = 59], functional dyspepsia [n = 53] and functional constipation [n = 61]) diagnosed by clinicians using Rome III criteria, negative alarm features and investigations.ResultsExperts noted words for constipation, bloating, fullness and heartburn, posed difficulty. The English back-translated questionnaires demonstrated concordance with the original EAR3Q. Sensitivity and specificity of the questionnaires were high enough to diagnose respective functional gastrointestinal disorders (gold standard: clinical diagnoses) in most except Korean and Indonesian languages. Questionnaires often uncovered overlapping functional gastrointestinal disorders. Test-retest agreement (kappa) values of the translated questionnaires were high (0.700–1.000) except in Korean (0.300–0.500) and Indonesian (0.100–0.400) languages at the initial and 2-week follow-up visit.ConclusionsThough Chinese, Hindi and Telugu translations were performed well, Korean and Indonesian versions were not. Questionnaires often uncovered overlapping FGIDs, which were quite common
