Prevalencia de síndrome de intestino irritable en América Latina / Irritable bowel syndrome prevalence in Latin America

El síndrome de intestino irritable es una enfermedad funcional intestinal frecuente a nivel mundial, pero con pocos estudios de prevalencia. Su diagnóstico es clínico y se basa en criterios acordados internacionalmente que han cambiado con el tiempo, actualmente regidos por el Consenso de Roma IV. Objetivo: Recabar y actualizar datos disponibles de prevalencia de América Latina para entender mejor el comportamiento regional de SII. Materiales y métodos: Se realizó una búsqueda de trabajos originales, autodefinidos de prevalencia, en las bases de datos Pubmed y Lilacs así como presentaciones en congresos de trabajos originales. Resultados: Se encontraron 27 estudios según los criterios de búsqueda establecidos. De ellos, 16 eran en población general. Dos trabajos incluyeron el estudio de prevalencia de más de una población constituyendo finalmente 22 referencias desarrolladas en 9 países. La prevalencia promedio total para América Latina fue 15,4%. La prevalencia promedio encontrada por criterios de Roma II fue 23,5%; por Roma III 11,8% y por Roma IV 6,98%. Conclusión: Esta es la primera revisión en reunir datos de prevalencia de síndrome de intestino irritable en población general de nueve países de América Latina. La prevalenci d fue amplia y los criterios diagnósticos utilizados hicieron la mayor diferencia.

Although irritable bowel syndrome is a common functional bowel disease worldwide, few prevalence studies have been published. Diagnosis is clinical and based on internationally agreed criteria that have changed over time. Currently the Rome IV Consensus is used as the international reference. Objective: collect and update available prevalence data from Latin America to better understand the regional behavior of irritable bowel syndrome. Materials and methods: a search was carried out for original works, self-defined on prevalence, in the Pubmed and Lilacs databases. Presentations or posters at congresses of original works were also considered. Results: according to the established search criteria, 27 studies were found. Of these, 16 were in the general population. Two studies included the study of the prevalence of more than one population, for which reason 22 prevalence data were obtained from 9 countries. The total average prevalence for Latin America was 15.4%. The average prevalence found by the Rome II criteria was 23.5%; by Rome III 11.8% and by Rome IV 6.98%. Conclusion: this is the first review to collect data on the prevalence of irritable bowel syndrome in the general population from nine Latin American countries. The average prevalence found was 15%. The variability was wide and the diagnostic criteria used made the biggest difference.

Irritable bowel syndrome in Indonesian adolescents

Abstract Objective: Irritable bowel syndrome is a frequent functional gastrointestinal disorder. The aims of this study were to investigate its epidemiology, focusing on the role of intestinal mucosal integrity and to evaluate the impact on the quality of life. Methods: A community-based survey applying a comparative cross sectional approach was conducted in six high schools in Palembang. Subjects were recruited using multistage random sampling divided in two groups. Rome III criteria were used to establish a diagnosis of IBS in combination with a questionnaire to determine risk factors. Determination of fecal alpha-1-antitrypsin and calprotectin levels was performed to determine impaired intestinal mucosal integrity. A questionnaire was used to evaluate how quality of life was affected by irritable bowel syndrome. Results: The survey was performed in 454 14−18 years old adolescents, of whom 30.2% fulfilled the Rome III criteria for IBS, with the following subtypes: 36.5% diarrhea, 18.9% constipation, 21.9% mixed, and 22.6% unclassified. Major risk factors were female gender, bullying, age 14-16 years, history of constipation and diarrhea, eating nuts, and drinking coffee, tea, and soft drinks. There was a significant association with intestinal inflammation (p = 0.013). A significantly impaired quality of life was found (p = 0.001). Conclusions: The prevalence of irritable bowel syndrome in adolescents was high, with bullying, female gender, age 14-16 years, constipation and diarrhea, and dietary consumption of soft drinks, coffee, and tea as risk factors. A significant association with intestinal inflammation was found.

Patologías funcionales post-infecciosas: epidemiología, factores de riesgo y tratamiento / Post-infectious functional gastrointestinal disorders: epidemiology, risk factors and treatment

Infectious gastroenteritis is a risk factor for developing post-infectious functional gastrointestinal disorders (PI-FGDs), mainly irritable bowel syndrome (IBS) and functional dyspepsia (FD). It is a significant subgroup of patients due to frequent episodes of gastrointestinal infections. Symptoms in PI-FGD patients can prevail for more than twelve months, especially if infective agents are bacteria or parasites. Symptoms are indistinguishable from their non-infective equivalents (IBS and FD). Risk factors for developing PI-FGD are: female gender, type and severity of the gastrointestinal infection, high anxiety levels and younger age. Main pathogenic mechanisms are alteration of permeability and immunity. Mucosa inflammation prevails only at early stage; however, with follow-up it can be reduced or normalized. Nevertheless, certain alterations prevail, such as hypersensitivity. These events are treated in the same way as IBS or FD.

La gastroenteritis infecciosa es un factor de riesgo para desarrollar un trastorno digestivo funcional postinfeccioso (TDF-PI), principalmente síndrome de intestino irritable (SII) y dispepsia funcional (DF). Es un subgrupo de pacientes relevante debido a lo frecuente que son las infecciones gastrointestinales. Los síntomas en los pacientes con TDF-PI se pueden prolongar por más de un año, especialmente cuando los agentes infecciosos son bacterias o parásitos. Los síntomas son indistinguibles con respecto a los de sus equivalentes no infecciosos (SII y DF). Los factores de riesgo para desarrollar TDF-PI son el sexo femenino, el tipo y la severidad de la infección gastrointestinal, los niveles altos de ansiedad, y la menor edad. Los principales mecanismos patogénicos son la alteración de la permeabilidad y de inmunidad. La inflamación de la mucosa predomina solo al principio pero con el seguimiento esta disminuye o se normaliza, a pesar de lo cual ciertas alteraciones como la hiperensibilidad permanecen. Estos cuadros se tratan de la misma manera que un SII o DF.

Influencia del polimorfismo genético rs2927488 de Bcl3 en el síndrome de intestino irritable / Influence of genetic polymorphism rs2927488 of the Bcl3 irritable bowel syndrome

Irritable Bowel Syndrome (IBS) is a functional disorder characterized by abdominal discomfort associated with changes in bowel habit and increased intestinal sensitivity. It is one of the most common disorders of digestive health in Chile as well as in the world. Although the pathophysiological mechanisms of IBS have yet to be fully established, it is known that (epi-) genetic factors are involved in the development of the disorder. Bcl3 (B-cell leukemia/lymphoma 3) is a regulatory protein of the intestinal inflammatory response, specifically, with regard to the signaling pathways of NF-kB (Nuclear Factor-kB). Among the variability of the human genome, the gene encoding Bcl3 contains the polymorphism SNPs rs2927488 (variants A/G) which has been associated with susceptibility to developing Inflammatory Bowel Disease (IBD). Furthermore, the presence of this polymorphic variant has been correlated with increased levels of Bcl3 gene expression in patients with Crohn’s Disease. Our laboratory is focused on understanding the potential relationship between Bcl3 and IBS. Our preliminary studies describe an increased expression of Bcl3 at the intestinal mucosal epithelium in IBS patients with a diarrheal-phenotype (IBS-D). We are now interested to investigate if the presence of the variant SNP rs2927488(A/G) is a susceptibility factor for IBS development and to understand the significance of its relationship with Bcl3 expression, in Chilean IBS patients. In this review, we focus primarily on the relationship between rs2927488(A/G) polymorphism of Bcl3 gene, its protein expression and its mechanisms of control over the inflammatory response...

Context The irritable bowel syndrome and primary headache are two chronic diseases characterized by symptoms of recurring pain and affect approximately 10%-20% of the general population. Objectives To study the prevalence of primary headache in volunteers with irritable bowel syndrome in a Brazilian urban community. Methods It was evaluated the prevalence of primary headache associated with irritable bowel syndrome in adult volunteers 330 no patients.The protocol included the Rome III criteria, international classification of Headaches, later divided into four groups: I- Irritable bowel syndrome (n = 52), II- Primary headache (n = 45), III-Irritable bowel syndrome (n = 26) and headache, and IV- Controls (207). Results We not found significant difference in the average age of the four groups and the diagnosis of irritable bowel syndrome, primary headache and their association was more frequent in females. The frequent use of analgesics was greater in groups II and III. Conclusion Our results suggest that irritable bowel syndrome and primary headache are also common in third world countries. The frequency in use of analgesics in association between the two entities was relevant. The identification of irritable bowel syndrome patients with different clinical sub-types could improve the therapeutics options and the prevention strategies. .

Irritable bowel syndrome in women with chronic pelvic pain in a Northeast Brazilian city / Síndrome do intestino irritável em mulheres com dor pélvica crônica em uma cidade do Nordeste Brasileiro

PURPOSES: To determine the prevalence of irritable bowel syndrome (IBS) in women with chronic pelvic pain (CPP) and its associated features; to determine whether IBS and CPP constitute the same syndrome. METHODS: Cross-sectional population survey with systematic sequential sampling according to census districts in which 1470 women were interviewed with respect to the sample calculation. The participants resided in their own homes, were at least 14 years of age, experienced menarche and presented CPP according to the American College of Obstetrics and Gynaecology. The dependent variable was IBS based on Rome III criteria in women with CPP, and the following independent variables were possibly associated with IBS: age, schooling, duration of pain, sedentary lifestyle, migraine, depression, insomnia, back pain, dysmenorrhea, dyspareunia, depression, history of violence, and intestinal symptoms. The sample was subdivided into groups with and without IBS. After the descriptive analysis of the variables was performed, the respective frequencies were evaluated using GraphPad Prism 5 software. To evaluate the association between the dependent variable and the independent variables, the χ² test was used with a significance level of 5%. RESULTS: The prevalence of IBS in women with CPP was 19,5%. Pain duration (p=0.03), back pain (p=0.002), history of physical or sexual abuse (p=0.002), and intestinal complaints were more prevalent in the group with IBS and CPP. There was no difference between the groups regarding other criteria. CONCLUSION: The data confirmed the literature, identified several aspects that were shared between the pathologies and supported the hypothesis that both pathologies can constitute the same syndrome.

OBJETIVOS: Verificar a prevalência da síndrome do intestino irritável (SII) em mulheres com dor pélvica crônica (DPC) e as características associadas; analisar se SII e DPC constituem a mesma síndrome. MÉTODOS: Estudo transversal do tipo inquérito populacional com amostragem sistemática sequencial de acordo com os distritos censitários, no qual 1470 mulheres foram entrevistadas conforme o cálculo amostral. Foram selecionadas aquelas residentes no respectivo domicílio, com pelo menos 14 anos de idade, que já haviam tido a menarca e apresentavam DPC de acordo com o Colégio Americano de Obstetrícia e Ginecologia. A variável considerada dependente foi a SII baseando-se nos Critérios de Roma III em mulheres com DPC, e as independentes, possivelmente associadas com a SII foram: idade, escolaridade, tempo de dor, sedentarismo, enxaqueca, depressão, insônia, lombalgia, dismenorreia, dispareunia, depressão, passado de violência e sintomas intestinais. A amostra foi subdividida nos grupos com e sem SII. Após a análise descritiva das variáveis, as respectivas frequências foram avaliadas utilizando GraphPad Prism 5. Para determinação da presença de associação entre a variável dependente e as independentes, utilizou-se o teste do χ² com nível de significância a 5%. RESULTADOS: A prevalência de SII em mulheres com DPC foi de 19,5%. O tempo de dor (p=0,03), a lombalgia (p=0,002), história de abuso físico ou sexual (p=0,002) e as queixas intestinais foram maiores no grupo com SII e DPC. Não houve diferença entre os grupos quanto aos demais critérios. CONCLUSÃO: Os dados confirmam a literatura, demonstrando muitos aspectos comuns entre as duas condições e valorizando a hipótese de que elas possam compor a mesma síndrome.

Impact of Shiftwork on Irritable Bowel Syndrome and Functional Dyspepsia

Disturbances in biological rhythms could lead to unfavorable health impact. This study aimed to evaluate the prevalence of functional dyspepsia (FD) and irritable bowel syndrome (IBS) in rotating shift workers, and to determine the factors that have significant association with the prevalence of FD and IBS. The research had been carried out among nurses and nursing assistants working at Ewha Womans University Mokdong Hospital between December 2010 and February 2011. The subjects completed self-reported questionnaires, including the quality of the sleep and the level of stress. The prevalence of FD and IBS defined by ROME III criteria, and factors associated the disorders in rotating shift workers were compared with those of day workers. A total of 207 subjects were included in the study with 147 rotating shift workers (71.0%), and 60 (29.0%) day workers. The prevalence of IBS in rotating shift workers was higher than that in day workers (32.7% vs 16.7%, P = 0.026). However, no significant difference in the prevalence of FD was observed between the two groups (19.7% vs 20.0%, P = 0.964). In the multivariate analysis, the risk factors for IBS were rotating shift work (OR, 2.36; 95% CI, 1.01-5.47) and poor sleep quality (OR, 4.13; 95% CI, 1.82-9.40), and the risk factors for FD were poor sleep quality (OR, 2.31; 95% CI, 1.01-5.28), and severe stress (OR, 2.19; 95% CI, 1.06-4.76). A higher prevalence of IBS among rotating shift workers could be directly associated with the circadian rhythm disturbance. The circadian rhythm disturbance may be related with the pathogenesis of IBS.

Conclusions: IBS prevalence on Chiclayo is high, more common in women and those who work or study; diarrhea, pasty feces and mesogastric pain were the most frequent clinical manifestations.

Epidemiological features of gastro-esophageal reflux disease in Iran based on general population

The aim of this study was to evaluate the epidemiology of GERD base on population study in Tehran providence. Gastro-esophageal reflux disease [GERD] is a common and chronic problem. Recent reports from developing counties indicate increment in the incidence and prevalence of the disease over the past. This study was a cross-sectional household survey conducted from May 2006 to December 2007 in Tehran province, Iran. Participants completed a valid gastro-esophageal reflux Questionnaire. The questionnaire included personal and family characteristics such as age, gender, and educational status. In addition, interviewers asked them regarding 10 GI symptoms. Altogether 18180 individuals participated in this cross-sectional study. The mean +/- SD age of participant was 38.7 +/- 17.1 and 9072 [49.9%] were women. The prevalence of GERD was 8.85 [8.43-9.26]. There was significant relationship between age, sex, marital and educational status with GERD. GERD symptoms were more common in women, older people, individuals with low education and married people. There was overlap between GERD, irritable bowel syndrome [IBS] and uninvestigated dyspepsia [UD]. According to our finding although the prevalence of GERD in our population is less than other studies, this prevalence is increasing in recent years

Natural History and Overlap of Functional Gastrointestinal Disorders / 대한소화기학회지

Functional gastrointestinal (GI) disorders are common in the general population. Based on the Rome III classification, these disorders are mutually exclusive disorders keeping the homogeneity of each functional GI disorder in research area. In contrast, many population and clinical studies have reported a considerably high rate of overlap between functional GI disorders. The overlap of functional GI disorders over other intestinal diseases might simply occur by chance due to a highly prevalent disorder. Moreover, functional GI disorders is considered a chronic stable disorder that may wax and wane for several years. However, a recent study about the natural history of functional GI disorders showed substantial transition among functional GI disorders over time. The natural history of functional GI disorders with overlapping other functional GI disorders are still in infancy and better understanding of these will be important in determining the efficacy of future therapeutic interventions.

Relationship between Irritable Bowel Syndrome, Worry and Stress in Adolescent Girls

The aim of this study is to investigate prevalence of irritable bowel syndrome (IBS) among adolescents and difference in worry and stress between normal and IBS groups. Questionnaire survey was conducted at a girl's middle and high school. Students from seventh to eleventh grade participated in the examination on Rome II criteria, lifestyle and dietary habits. Worry and stress were measured with the Korean version Penn State Worry Questionnaire-Children and the Korean version Brief Encounter Psychosocial Instrument. Worry score was significantly higher in the IBS group (22.07 +/- 9.38, P < 0.001) than in the normal group (18.65 +/- 8.99) and was higher in high school students than in middle school students (P = 0.02). Stress score also was higher in the IBS group than in the normal group (P < 0.001) and was higher in the high school girls than in the middle school ones (P = 0.04). Of all the lifestyle factors influencing IBS preference for fatty foods, preference for salty foods, drinking alcohol and sleeping for less than six hours a day were found to be significant. Worry and stress seem to be associated with IBS symptoms. The findings of this study draw a clue that less worry and stress will help decrease IBS symptoms.

Relationship between Irritable Bowel Syndrome, Worry and Stress in Adolescent Girls

The aim of this study is to investigate prevalence of irritable bowel syndrome (IBS) among adolescents and difference in worry and stress between normal and IBS groups. Questionnaire survey was conducted at a girl's middle and high school. Students from seventh to eleventh grade participated in the examination on Rome II criteria, lifestyle and dietary habits. Worry and stress were measured with the Korean version Penn State Worry Questionnaire-Children and the Korean version Brief Encounter Psychosocial Instrument. Worry score was significantly higher in the IBS group (22.07 +/- 9.38, P < 0.001) than in the normal group (18.65 +/- 8.99) and was higher in high school students than in middle school students (P = 0.02). Stress score also was higher in the IBS group than in the normal group (P < 0.001) and was higher in the high school girls than in the middle school ones (P = 0.04). Of all the lifestyle factors influencing IBS preference for fatty foods, preference for salty foods, drinking alcohol and sleeping for less than six hours a day were found to be significant.

Role of psychiatric disorders and irritable bowel syndrome in asthma patients

OBJECTIVES: The goals of the study were the following: 1) to determine the frequency of psychiatric disorders and irritable bowel syndrome in patients with asthma and 2) to compare the frequency of these disorders in patients with asthma to their frequency in healthy controls. INTRODUCTION: Patients with asthma have a higher frequency of irritable bowel syndrome and psychiatric disorders. METHODS: We evaluated 101 patients with bronchial asthma and 67 healthy subjects. All subjects completed the brief version of the Bowel Symptoms Questionnaire and a structured clinical interview for DSM-IV axis disorders (SCID-I/CV). RESULTS: There were 37 cases of irritable bowel syndrome in the group of 101 stable asthma patients (36.6 percent) and 12 cases in the group of 67 healthy subjects (17.9 percent) (p = 0.009). Irritable bowel syndrome comorbidity was not related to the severity of asthma (p = 0.15). Regardless of the presence of irritable bowel syndrome, psychiatric disorders in asthma patients (52/97; 53.6 percent) were more common than in the control group (22/63, 34.9 percent) (p = 0.02). Although psychiatric disorders were more common in asthma patients with irritable bowel syndrome (21/35, 60 percent) than in those without irritable bowel syndrome (31/62, 50 percent), the difference was not significant (p = 0.34). In asthma patients with irritable bowel syndrome and psychiatric disorders, the percentage of forced expiratory volume in 1 s (FEV1) was lower than it was in those with no comorbidities (p = 0.02). CONCLUSIONS: Both irritable bowel syndrome and psychiatric disorders were more common in asthma patients than in healthy controls. Psychiatric disorders were more common in asthma patients with irritable bowel syndrome than in those without irritable bowel syndrome, although the differences failed to reach statistical significance. In asthma patients with IBS and psychiatric disorders, FEV1s were significantly lower than in other asthma patients. It is important for clinicians to accurately recognize that these comorbid conditions are associated with additive functional impairment.

Functional bowel disorders in Iranian population using Rome III criteria

To study the prevalence and risk factors of functional bowel disorders [FBD] in Iranian community using Rome III criteria. This study was a cross-sectional household survey conducted from May 2006 to December 2007 in Tehran province, Iran, including 18, 180 participants who were selected randomly and interviewed face-to-face by a validated questionnaire based on Rome III criteria. In all, 1.1% met the Rome III criteria for irritable bowel syndrome [IBS], 2.4% for functional constipation [FC], and 10.9% of the participants had any type of FBD. Among participants with functional dyspepsia, 83.3% had FBD; the majority cases were unspecified functional bowel disorder [U-FBD]. Of the subjects fulfilling the IBS criteria, IBS with constipation [52%] was the most frequent subtype. In the multivariate analysis, women had a higher risk of any FBDs than men, except for functional diarrhea [FD]. The prevalence of FBD, FC and FD increased and IBS decreased with increasing age. Marital status was only associated with a decrease in the risk of FBD and FD, respectively. IBS subtypes compared with FC and FD. There was no significant difference between FC and IBS with constipation [IBS-C], except for self-reported constipation; while, IBS with diarrhea [IBS-D] had more symptoms than FD. This study revealed a low rate of FBDs among the urban population of Tehran province. The ROME III criteria itself, and the problems with interpretation of the data collection tool may have contributed in underestimating the prevalence of FBD. In addition the reliability of recall over 6 months in Rome III criteria is questionable for our population
