RESUMEN

BACKGROUND: In Europe, an herbal medicine containing peppermint oil is widely used in patients with irritable bowel syndrome (IBS). In Japan, however, no clinical evidence for peppermint oil in IBS has been established, and it has not been approved as a drug for IBS. Accordingly, we conducted a clinical study to confirm the efficacy and safety of peppermint oil (ZO-Y60) in Japanese patients with IBS. METHODS: The study was a multi-center, open-label, single-arm, phase 3 trial in Japanese outpatients with IBS aged 17-60 years and diagnosed according to the Rome III criteria. The subjects were treated with an oral capsule of ZO-Y60 three times a day before meals, for four weeks. The efficacy of ZO-Y60 was evaluated using the patient's global assessment (PtGA), IBS symptom severity score, stool frequency score, stool form score, and physician's global assessment (PGA). The safety of ZO-Y60 was also assessed. RESULTS: Sixty-nine subjects were treated with ZO-Y60. During the four-week administration of ZO-Y60, the improvement rate of the PtGA was 71.6% (48/67) in week 2 and 85.1% (57/67) in week 4. It was also suggested that ZO-Y60 is effective against any type of IBS (IBS with constipation, IBS with diarrhea, and mixed/unsubtyped IBS). The improvement rate of the PGA was 73.1% (49/67) in week 2 and 85.1% (57/67) in week 4, also confirming the efficacy of ZO-Y60. Adverse events were observed in 14 subjects (20.3%), however, none of these adverse events were categorized as serious. CONCLUSION: The efficacy of treatment was confirmed, subjective symptoms were improved, as was observed in previous clinical studies of ZO-Y60 conducted outside of Japan. All adverse reactions were previously known and were non-serious. These findings suggest that peppermint oil may be effective in the Japanese population and that it has an acceptable safety profile.

RESUMEN

Objective: This study aimed to investigate the prevalence and clinical characteristics of subjective constipation in Chinese patients with multiple system atrophy (MSA), as well as the timing of constipation onset relative to the occurrence of motor symptoms. Methods: A total of 200 patients who were consecutively admitted to two large Chinese hospitals from February 2016 to June 2021 and subsequently diagnosed with probable MSA were enrolled in this cross-sectional study. Demographic and constipation-related clinical data were collected, and motor and non-motor symptoms were assessed using various scales and questionnaires. Subjective constipation was defined using ROME III criteria. Results: The frequency of constipation was 53.5, 59.7, and 39.3% in MSA, MSA with predominately parkinsonism (MSA-P), and MSA with predominately cerebellar ataxia (MSA-C), respectively. MSA-P subtype and high total UMSARS scores were associated with constipation in MSA. Similarly, the high total UMSARS scores were associated with constipation in MSA-P and MSA-C patients. Among the 107 patients with constipation, 59.8% began experiencing it before the onset of motor symptoms, and the interval between constipation and occurrence of motor symptoms was significantly longer in these patients than in those who experienced constipation after onset of motor symptoms. Conclusion: Constipation is a highly prevalent non-motor symptom in MSA and more often occurs before the onset of motor symptoms. The results of this study may help guide future research into MSA pathogenesis in its earliest stages.

RESUMEN

AIM: During infancy bowel habits change. Most infants with gastrointestinal problems have a functional gastrointestinal disorder (FGID), a major reason for visiting paediatricians. This study aims to provide data on stool frequency and consistency during the first year, prevalence rates for functional constipation (FC) and to establish associations with relevant demographic data. The occurrence of infant colic (IC) and infant dyschezia (ID) was also reported. METHODS: This prospective observational birth-cohort study enrolled 122 healthy full-term infants. Questionnaires were completed at 2 weeks and 2, 6 and 12 months. RESULTS: Stool frequency decreased with age and consistency changed, with fewer runny stools. At 2 weeks, 24.3% had at least one of the studied FGID. FC was found in 2.6%-14.3% (up to 12 months), IC was found in 4.9%-3.4% (up to 2 months) and ID in 22.1%-3.9% (up to 6 months). Infants with an FGID had a lower weight and more healthcare visits than infants without. Breastfeeding and a high percentage of runny stools at 2 weeks of age decreased the odds of developing FC. CONCLUSION: Data on bowel habits and the prevalence of FC, IC and ID are presented. FGID during infancy is common and affects children's well-being, while their families need support and advice.

RESUMEN

BACKGROUND: Cyclic vomiting syndrome (CVS) is recognized as an episodic syndrome associated with migraine in the last version of the International Classification of Headache Disorders (ICHD-3). It manifests as stereotypical episodes of intense nausea and vomiting, occurring preferentially in childhood. Over the last 2 decades, the knowledge of this disorder has increased. The diagnostic criteria have been modified, through the evolution of several successive classifications. Actually, two classifications are prominent in the literature: the ICHD-3 and the Rome IV classification. The predictable periodicity of episodes is only recognized in the ICHD-3. OBJECTIVE: We aimed to analyze the evolution of CVS literature in the last 2 decades, with a focus on CVS criteria used in these papers. METHODS: We conducted a bibliometric study. We searched in the Web of Science database all papers in English literature with the term CVS in the abstract or title, in the category "article" or "review", published from 2001 to 2020. We searched within the paper which classification was used or mentioned. RESULTS: In total, 213 papers were analyzed. 116 papers exclusively concerned childhood and adolescence CVS, or were written by pediatric practitioners. For most of the papers, the corresponding author was specialized in the field of gastroenterology. The Rome III classification was the main classification used or mentioned. The ICHD-3 and its beta version were mostly used or mentioned by the authors affiliated to the neurologic field. CONCLUSION: This study shows the growth in the number of publications on CVS. It highlights the lack of reference to the ICHD, in particular by practitioners in the field of gastroduodenal disorders. This should encourage the achievement of a common classification with the different scientific societies.

RESUMEN

Background: Constipation is one of the most common gastrointestinal disorders. The prevalence of constipation is rapidly increasing globally. It has adverse effects on the patient's quality of life including productivity and results in a high financial hardship on the healthcare system. The aim of the study was to estimate the symptoms and prevalence of constipation among the adult population of Bangladesh. Materials and methods: It was a cross-sectional observational study based on a structured questionnaire and a checklist. In this study, three criteria were used for the diagnosis of chronic constipation (self-reported perception, Rome III criteria, and Bristol's criteria). The study was conducted among 1,550 population between July 2019 and December 2019. Result: The study population consisted of 1,550 respondents, among them 41.61% male and 58.39% female, and the mean age was 32.71 ± 9.72 years. In the study, 12.2% of the population was categorized to have constipation according to self-reported perception, 11.2% according to Rome III, and 10.3% reported to have been suffering from constipation according to Bristol chart.Female gender tends to have a greater prevalence than male. In multivariate analysis for constipation, betel nut chewer, alcohol consumer, diabetes mellitus, hypertension, GI surgery, and bronchial asthma were significantly (p < 0.001) associated with constipation. According to Bristol's criteria, the most common stool form was Type III (sausage-shaped with cracked surface) among the Bangladeshi population in this study. Conclusion: Chronic constipation is a common problem worldwide. The findings of this study suggest that there is a high prevalence of constipation among the general population of Bangladesh. Decreasing modifiable risk factors of constipation can reduce its prevalence and burden of the disease. Bangladesh is markedly deficient in literature citing constipation prevalence and determinants. These findings may commence a call for setting priority as one of the major public health problems and demanding attention for both at the clinical and community levels.

RESUMEN

BACKGROUND: Approximately 90% of the children with chronic abdominal pain are diagnosed as having functional abdominal pain disorder (FAPD). The Dutch guideline "functional abdominal pain" provides a stepwise approach to treat FAPD. The aim of this survey was twofold first, to determine adherence to the Dutch guideline, and second to determine current management of FAPDs in clinical practice. METHODS: A multicenter survey was designed. The survey was sent to pediatricians and pediatric residents in December 2020. The study ran from October 2020 until March 2021. Participants in ten hospitals in the western region of The Netherlands were invited to complete this survey. Respondents who indicated not to treat children with FAPDs or respondents who completed less than 3 steps of the survey were excluded. RESULTS: In total, 85/174 (48.9%) respondents completed the survey. We included 80 respondents, 68 pediatricians and 12 pediatric residents, for analysis. Overall, self-reported guideline adherence was 85%. Self-reported adherence was higher than actual adherence. Only 50% of all respondents followed the first three steps of the guideline. The reported non-pharmacological and pharmacological treatments were diverse and varied between different age groups. The average follow-up duration was between 2 and 6 months, and the most regularly used outcome measures were attendance at school, quality of life, and adequate pain relief/reassurance. CONCLUSION: We reportedly observed a large variation in the management of children with FAPDs, due to low guideline adherence among clinicians. Improved guideline adherence may be accomplished by updating the guideline with specific recommendations per subtype, follow-up and outcome measures as well measures to improve guideline implementation.

RESUMEN

Introduction: irritable bowel syndrome is a recurrent chronic gastrointestinal functional disorder. Despite it is not dangerous; it carries a significant feedback on self-confidence and quality of life. Medical students are expected to develop irritable bowel syndrome because they are subjected to stress due to over academic pressure. The objectives were to investigate irritable bowel syndrome prevalence, and to detect the related risk factors in this specific group of Egyptian people. Methods: this cross-sectional study performed in two faculties of medicine in Nile Delta, Egypt. It had been built on self-administered questionnaires including Rome III criteria for diagnosis of irritable bowel syndrome, as well as several questions for gathering socio-demographic information and manifestations suggesting irritable bowel syndrome. Results: fifty (27.5%) of 182 evaluated medical students achieved criteria of irritable bowel syndrome, 64% of them were mixed type. Irritable bowel syndrome had a significant relationship with coffee, milk products, fewer vegetables, and fruits intake (P=0.034, P=0.044, P<0.001 respectively). Depression, anxiety, and food intolerance were detected to be significantly related to irritable bowel syndrome (p<0.001, p=0.005, p=0.04) respectively. Conclusion: it was demonstrated that many Egyptian medical students were suffering from irritable bowel syndrome. Some dietary habits, anxiety, and depression of the students could be risk factors related to development of irritable bowel syndrome.

RESUMEN

Background: Irritable bowel syndrome (IBS) is a very common gastrointestinal disorder worldwide, but research regarding this disease is rare in Bangladesh. This study aimed to assess the prevalence of IBS and its associated risk factors among university students in Bangladesh. Methods: This is a cross-sectional study. A total of 300 randomly selected participants were included in this study. By using a structured questionnaire and anthropometric methods, we collected all the required data for our study. The diagnosis of IBS was based on Rome III criteria. Results: The overall prevalence of IBS was 39.3%, but the majority (77.3%) had no basic awareness of IBS. In our study, anxiety and depression (χ 2 = 6.817; odds ratio [OR] = 1.910; 95% confidence interval [CI] = 1.172, 3.113; P = 0.011) had a significant relationship with IBS and IBS had a significant (P < 0.001) relationship with food intolerance (χ 2 = 8.737; OR = 2.130; 95% CI = 1.284, 3.531), chest pain (χ 2 = 7.482; OR = 2.035; 95% CI = 1.218, 3.401), and insomnia (χ 2 = 19.320; OR = 2.907; 95% CI = 1.794, 4.709). In our dietary data, the intake patterns of vegetables (P = 0.000), fast food (P = 0.000), and tea-coffee (P = 0.003) showed a strong significant association with IBS. On the other hand, monthly household income (P = 0.154) and body mass index (BMI) (P = 0.138) showed no significant association with IBS. Among our study subjects, IBS-constipation (54.2%) was more common than IBS-diarrhea (27.1%) and IBS-mixed (18.6%). Moreover, among the 118 IBS respondents, 67.8% had a headache with increased flatulence (95.8%) as the most common IBS-related complication. Conclusion: IBS is common in university students of Bangladesh and is associated with anxiety, depression, and particular dietary patterns.

RESUMEN

Functional gastrointestinal disorders (FGIDs) are highly prevalent in medical students around the world. However, there is no specific data on FGIDs in Tunisia. The objectives of this study were to evaluate the prevalence of FGIDs in medical students according to the rome III criteria and to identify risk factors associated with these disorders. A self-administered questionnaire survey was carried out among the students from the first and the second year of medical studies. We studied the influence of socio-demographic characteristics, lifestyle, health care seeking, psychosomatic symptoms and hospital anxiety and depression scale on the prevalence of FGIDs among these students. Three hundred and forty-three students (20.3 ± 0.8years) were included in our study. The prevalence of FGIDs was 54.2%. The main FGIDs found were the unspecified functional bowel disorder (46.6%), functional constipation (11.6%), irritable bowel syndrome (7.6%) and functional dyspepsia (6.7%). In logistic regression, abnormal BMI (OR = 2.1, 95% CI= 1-4.3), living in school dormitory (OR = 3.7, 95% CI = 1.7-7.8), low water intake (OR = 2.2, 95% CI = 1.1-4.2), digestive medication use (OR = 3.4, 95% CI= 1.3-8.5), and probable or definite anxiety (OR = 2.5, 95% CI = 1.1-5.8) were the five risk factors associated with FGIDs. We demonstrate a high prevalence of FGIDs (54.2%) among our students. Risk factors for FGIDs were abnormal BMI, living in school dormitory, low water intake, digestive medication use and anxiety.

RESUMEN

Background: The newly released Rome criteria in 2016 has a stricter and more precise definition of functional gastrointestinal disorders (FGIDs) when compared with Rome III criteria. The adjustment and improvement of diagnostic criteria by Rome criteria may affect the clinical diagnosis of FGIDs. Aims: To investigate the differences and the similarities between Rome III and Rome criteria in the diagnosis of FGIDs in college students. Methods: The FGIDs database of college students in Zhejiang Province established by our previous research team were further evaluated and analyzed by Rome criteria, and the incidence, psychological symptom score, overlapping of disease of FGIDs were calculated, and compared with Rome III criteria. Results: Of the 1 870 cases in database, 1 025 (54.81%) met Rome criteria of FGIDs; while 1 111 (59.41%) met Rome III criteria, the difference in detection rate was statistically significant (P <0.01). In Rome group, incidences of belching disorders (2.14% vs. 5.83%, P<0.01), irritable bowel syndrome (IBS) (2.78% vs. 6.90%, P<0.01), functional abdominal bloating/distension (1.28% vs. 4.12%, P<0.01) were significantly lower than those in Rome III group, while incidence of functional diarrhea was significantly higher (3.85% vs. 0.70%, P<0.01). Patients met Rome criteria showed a higher score of obsession⁃compulsion, depression and anxiety (P<0.05). Rome criteria caused 33 (25.58%) original IBS patients included in functional diarrhea, and 6 (4.65%) original IBS patients included in function constipation. The diagnosis of functional bowel disease overlapping with other FGIDs (belching disorders, functional dyspepsia) according to Rome III and Rome criteria were statistically different (P<0.01, P<0.05). Conclusions: Rome criteria has a stricter and more accurate definition of FGIDs, reflecting a more accurate psychological and clinical features, and identification of patients who really need treatment, resulting in a more efficient and feasible application in clinical practice and scientific research.

RESUMEN

BACKGROUND: Neurogenic bowel dysfunctions (NBDs) in the form of both fecal incontinence (FI) and functional constipation (FC) are frequent in multiple sclerosis (MS) patients and significantly affect their quality of life. Therapeutic options are limited. OBJECTIVE: To investigate effectiveness of percutaneous posterior tibial nerve stimulation (PTNS) in MS patients suffering from FI and FC. METHODS: Prevalence and severity of FI and FC were prospectively collected among MS patients undergoing 12 weeks of PTNS for neurogenic bladder. The Cleveland Clinic Fecal Incontinence Score (CCFIS) and the Rome III criteria were used to define FI and FC, respectively. Subjective treatment satisfaction was estimated using the Benefit Satisfaction and Willingness to Continue (BSWC) questionnaire. RESULTS: A total of 60 patients undergoing PTNS suffered from NBDs (25 FI+/FC+, 5 FI+/FC-, 30 FI-/FC+). Median CCFIS decreased after PTNS from 12.0 (11.0-13.0) to 8.5 (7.0-11.0, p < 0.001), with particular improvements in liquid and flatal incontinence, pads' need, and lifestyle restrictions. Seven patients became FC free after PTNS and no patients developed FC during the study (p = 0.023). More than 50% of the patients were satisfied and willing to continue PTNS at study end. CONCLUSION: PTNS represents a valid minimally invasive alternative treatment for MS patients suffering from NBDs.

RESUMEN

BACKGROUND: In Japan, the prevalence of constipation-predominant irritable bowel syndrome (IBS-C) and functional constipation (FC) diagnosed by the Rome III criteria is unclear, as are the demographic profile, quality of life (QOL), and habits of persons with IBS-C or FC. METHODS: We performed an internet survey of constipation. After extracting 3000 persons fitting the composition of the general Japanese population, we investigated demographic factors, lifestyle, defecation, and laxatives. IBS-C and FC were diagnosed by Rome III criteria. Respondents also completed the Japanese IBS severity index (IBS-SI-J), Japanese IBS QOL scale (IBS-QOL-J), SF-8, Hospital Anxiety and Depression Scale (HADS), and Japanese Health Practice Index (JHPI). RESULTS: There were 262 respondents with FC (8.73%) [73 men and 189 women; mean age: 49.8 ± 13.1 years; mean body mass index (BMI): 21.0 ± 3.3 g/m2] and 149 respondents with IBS-C (4.97%) (76 men and 73 women; mean age; 41.6 ± 13.7 years; mean BMI: 20.8 ± 3.0 kg/m2). Total IBS-QOL-J score were significantly lower in the IBS-C group than the FC group. With regard to SF-8, score of mental component summary (MCS) was significantly lower in the IBS-C group. The total IBS-SI-J score and item scores, except for satisfactory defecation, were significantly higher in the IBS-C group than the FC group. HADS showed a significant increase of anxiety and depression in both the groups, and the JHPI revealed insufficient sleep. CONCLUSIONS: In Japan, among the population of under 70 years old, the prevalence of IBS-C and FC (Rome III criteria) was 4.97% and 8.76%, respectively. IBS-C caused more severe symptoms than FC, resulting in impairment of QOL.

RESUMEN

BACKGROUND: The symptoms of irritable bowel syndrome (IBS) lead to considerable impairment of health-related quality of life and high health care costs. Available therapies are not efficient in treating the symptoms of IBS. Studies have shown the beneficial effects of Saccharomyces cerevisiae CNCM I-3856. Therefore, this study was done to evaluate the efficacy and safety of S. cerevisiae CNCM I-3856 in the treatment of IBS. METHODS: This was a prospective, randomized, placebo-controlled study. One hundred newly diagnosed subjects with IBS were subgrouped into IBS-D, IBS-C, and IBS-M and then randomized to the S. cerevisiae CNCM I-3856 and placebo groups. Saccharomyces cerevisiae/placebo was administered in addition to standard treatment for a period of 8 weeks. Subjects were assessed for improvement of abdominal pain and change in stool consistency using a 7-point Likert scale and Bristol stool scale respectively. RESULTS: The mean reduction of abdominal pain score in the S. cerevisiae CNCM I-3856 group was statistically significant when compared with the placebo group (p < 0.001). Similar improvement was also seen in the subgroups. Improvement in stool consistency in IBS-D subgroup at the end of treatment period was found to be statistically significant in S. cerevisiae group when compared to that of placebo (p < 0.001). A similar improvement was seen in the IBS-C and IBS-M subgroups. No serious adverse events were recorded in both groups. CONCLUSION: The use of Saccharomyces cerevisiae CNCM I-3856 in IBS at a dose of 2 billion CFU twice daily for 8 weeks has shown to have an improvement in abdominal pain and stool consistency due to its analgesic and anti-inflammatory activity in subjects with IBS.

RESUMEN

OBJECTIVES: Few studies have examined the effects of applying the Rome IV criteria for irritable bowel syndrome (IBS) vs the previous standard, the Rome III criteria. We conducted a cross-sectional survey of individuals who self-identify as having IBS to examine this issue. METHODS: We collected complete demographic, symptom, mood, and psychological health data from 1375 adults who self-identified as having IBS, but were not recruited from a referral population. We applied the Rome III and the Rome IV criteria simultaneously to examine what proportion met each of these diagnostic criteria for IBS. We measured the level of agreement between the Rome III and Rome IV criteria, and assessed for presence of an alternative functional bowel disorder in individuals who no longer met diagnostic criteria for IBS with the more restrictive Rome IV criteria. Finally, we compared characteristics of individuals who met only Rome III criteria with those who met Rome IV criteria. RESULTS: In total, 1080 of 1368 individuals (78.9%) with IBS met the Rome III criteria. In contrast, 811 of 1373 individuals (59.1%) with IBS met the Rome IV criteria. Agreement between the criteria was only moderate (Kappa = 0.50). Among those who no longer had IBS according to the Rome IV criteria, 33 (11.5%) met Rome IV criteria for functional constipation, 118 (41.3%) for functional diarrhea, 68 (23.8%) for functional abdominal bloating or distension, and 67 (23.4%) for an unspecified functional bowel disorder. Individuals with Rome IV-defined IBS had more severe symptoms, and a higher proportion had a mood disorder and evidence of poor psychological health, compared with individuals who only met the Rome III criteria for IBS (P < .001). CONCLUSIONS: The characteristics of people who believe they have IBS differ between those who meet criteria as defined by Rome IV vs Rome III, including the spectrum of disease severity. Studies are needed to determine how these changes will affect outcomes of clinical trials.

RESUMEN

Abstract Background Irritable bowel syndrome (IBS) is a common gastrointestinal disorder; celiac disease is an autoimmune enteropathy that can mimic any functional gastrointestinal disorder. The aim of this study is to estimate the prevalence of celiac disease antibodies (anti Tissue Transglutaminase-tTG) in patients with irritable bowel syndrome. Patients and methods This cross sectional study was conducted on 70 patients with irritable bowel syndrome fulfilling Rome III criteria who visited Azadi Teaching Hospital in Duhok city-Iraq. Patients were classified according to irritable bowel syndrome subtypes into: Diarrhoea Predominant (D-IBS), Constipation Predominant (C-IBS) and Mixed (M-IBS). IgA and IgG anti tTG were used to screen patients for celiac disease. Results A total number of 70 patients (44 females and 26 males) were included; their mean age was 33 years (SD ± 7.64). Five patients (7.1%) were found to have positive both IgA and IgG anti tTG. Three of them have had D-IBS and the other two had C-IBS. No one of the M-IBS patients tested positive. Conclusion The prevalence of anti tTG antibodies in irritable bowel syndrome is high. Patients with D-IBS should be screened for celiac disease.

Resumo Introdução A síndrome do intestino irritável (SII) é um distúrbio gastrointestinal comum; a doença celíaca é uma enteropatia autoimune que pode imitar qualquer distúrbio gastrointestinal funcional. O objetivo deste estudo foi estimar a prevalência de anticorpos contra a doença celíaca (antitransglutaminase tecidual - tTG) em pacientes com SII. Pacientes e Métodos Este estudo transversal foi conduzido em 70 pacientes com síndrome do intestino irritável que atendiam aos critérios de Roma III e se apresentaram ao Hospital de Ensino Azadi na cidade de Duhok, no Iraque. Os pacientes foram classificados de acordo com os subtipos de síndrome do intestino irritável em: predominantemente diarreia (D-SII), predominantemente constipação (C-SII) e mista (M-SII). IgA e IgG antitTG foram usados para rastrear pacientes com doença celíaca. Resultados Um total de 70 pacientes (44 mulheres e 26 homens) foram incluídos; a idade média foi de 33 anos (DP ± 7,64). Cinco pacientes (7,1%) apresentaram IgA e IgG antitTG positivos. Três deles tinham D-SII e os outros dois tinham C-SII. Nenhum dos pacientes com M-SII apresentou teste positivo. Conclusão A prevalência de anticorpos antitTG na SII é alta. A presença de doença celíaca deve ser avaliada em pacientes com D-SII.

RESUMEN

INTRODUCTION: This study was conducted to determine the prevalence of constipation in infants aged 0-12 months in rural areas of Turkey. The study sample consisted of 203 mothers with infants aged 0-12 months. METHODS: Data were collected between April and June 2016, using the Rome III criteria and the Bristol stool chart. The data were analysed with χ2 analysis to compare the rate of the incidence of constipation according to variables and logistic regression (enter) analysis to evaluate all variables that have an effect on the incidence of constipation. RESULTS: Although the parents participating in the study stated that 19.7% of infants had constipation, applying the Rome III criteria showed the prevalence of constipation declined to 17.7%. Of the cases of constipation, 44.4% were female and 55.6% were male. A total of 32.1% of the non-breastfed infants were constipated and 30.2% of the infants who were started on supplementary food before age 6 months were constipated. In 50% of the cases of infants with constipation, the mothers also suffered from constipation. As a result, it was determined thatabout one fifth of the infants living in rural areas of Turkey have constipation. CONCLUSION: Education and counselling should be provided by primary healthcare institutions to the families who are part of groups at risk for constipation. It is also suggested that studies should be conducted to increase parents' knowledge and awareness of constipation.

RESUMEN

Objective: To compare the prevalence of anxiety and depression states and eating disorders (EDs) between patients with irritable bowel syndrome (IBS) and healthy volunteers without IBS. Methods: IBS patients according to Rome III criteria referred to our tertiary care center for therapeutic management and matched volunteers without IBS were prospectively included. EDs were screened by Sick, Control, One stone, Fat, Food-French version (SCOFF-F) questionnaire. IBS symptom severity (IBS symptom severity score), stool consistency (Bristol stool scale), anxiety and depression levels (Hospital Anxiety and Depression scale), and quality of life (validated Gastrointestinal Quality of Life Index) were assessed by validated self-questionnaires. Results: IBS (228) patients and healthy volunteers (228) were included. Mean age was 42.5 ± 13.9 years with mainly women (76.7%). Among IBS patients, 25.4% had positive SCOFF-F compared to 21.1% of volunteers. IBS patients more frequently had a lower body mass index (BMI) than volunteers (p < 0.0001). IBS patients with ED had poorer quality of life and more stressful life events (p = 0.02) than IBS patients without ED. The prevalence of anxiety and depression was significantly higher in IBS patients with ED than in volunteers without ED, respectively (19.0% vs 1.9%, p=0.00, and 60.3% vs 19.7%, p < 0.0001). Conclusions: The prevalence of ED assessed with positive SCOFF-F questionnaire was not significantly different between IBS patients and healthy volunteers. The combination of IBS and ED was associated with higher levels of anxiety or depression and poorer quality of life.

RESUMEN

Synbiotics approach complementarily and synergistically toward the balance of gastrointestinal microbiota and improvement in bowel functions. A randomised, double-blind, placebo-controlled study was conducted to examine the effects of a synbiotics supplement among constipated adults. A total of 85 constipated adults, diagnosed by Rome III criteria for functional constipation were randomised to receive either synbiotics (n = 43) or placebo (n = 42) once daily (2.5 g) in the morning for 12 weeks. Eight times of follow-up was conducted every fortnightly with treatment response based on a questionnaire that included a record of evacuation (stool frequency, stool type according to Bristol Stool Form Scale), Patients Assessment on Constipation Symptoms (PAC-SYM), and Patients Assessment on Constipation Quality of Life (PAC-QOL). There were no significant differences in stool evacuation, but defecation frequency and stool type in treatment group were improved tremendously than in placebo group. While the treatment group was reported to have higher reduction in severity of functional constipation symptoms, the differences were not statistically significant. Dietary supplementation of synbiotics in this study suggested that the combination of probiotics and prebiotics improved the functional constipation symptoms and quality of life although not significant. This was due to the high placebo effect which synbiotics failed to demonstrate benefit over the controls.

RESUMEN

BACKGROUND: The phenotypes of heartburn patients are heterogeneous. OBJECTIVE: The objective of this study was to investigate the proportion of heartburn phenotypes in a Chinese population and to compare the Rome IV and III criteria for heartburn diagnosis. METHODS: A retrospective study was performed among heartburn patients referred for upper endoscopy and esophageal function tests in a tertiary hospital. Their symptoms fulfilled Rome IV and III criteria. RESULTS: A total of 233 patients were included. Fifty-nine patients (25%) were diagnosed with esophagitis, 96 (41%) with non-erosive reflux disease (NERD) and 78 (34%) with functional heartburn (FH) based on Rome III criteria. Approximately 70% of the Rome III NERD patients were changed based on Rome IV criteria, with 36 patients (15%) diagnosed with reflux hypersensitivity (RH) and 32 patients (14%) who didn't fulfill the criteria considered unclassified. The FH and RH patients showed higher esophagogastric junction-contractile integral (EGJ-CI) and less hiatal hernia than did Rome IV NERD patients. The unclassified had more hiatal hernias than the FH and RH (p < 0.05). The EGJ-CI was similar between Rome III NERD and FH cases. CONCLUSION: The Rome IV criteria were stricter for heartburn diagnosis and superior in distinguishing NERD from functional disorders on motility patterns than Rome III.

RESUMEN

BACKGROUND: Functional dyspepsia (FD) is considered a bio-psychosocial disorder. The role of psychosocial factors in FD pathogenesis remains unclear. METHODS: This study evaluated sleep quality and mood symptoms in patients with FD, assessing the associations of FD severity, disordered sleep, and psychological symptoms. One-hundred-and-fifteen adult patients with typical FD symptoms were enrolled alongside 61 healthy volunteers. Rome III criteria were used to evaluate FD symptoms; sleep disorder was assessed with the Pittsburgh Sleep Quality Index (PSQI), and Symptom Checklist-90-Revised (SCL-90R) was utilized to determine the status of depression, anxiety and other psychological symptoms. RESULTS: PSQI scores and nine symptomatic dimensions of SCL-90R were significantly higher in FD patients than in controls. Multiple logistic regression indicated that lower BMI, lower level of education, and sleep disturbance were independently associated with FD and FD subgroups. Hostility and phobic anxiety were independent risk factors for FD. Further analysis showed that hostility was an independent risk factor for both FD subgroups, and somatization and additional psychiatric symptoms for epigastric pain syndrome. CONCLUSIONS: We found that FD was associated with sleep disorder and psychopathological factors. These findings suggest that implementing sleeping and/or psychological therapies may help reduce FD symptoms.
