The aims of this exploratory study were to examine whether tryptophan hydroxylase ( TPH) gene polymorphisms are associated with psychosocial factors in women with irritable bowel syndrome (IBS). TPH is the rate-limiting enzyme in the biosynthesis of serotonin and has two isoforms, TPH1 and TPH2. Four single nucleotide polymorphisms (SNPs) in the TPH1 gene and one SNP in the TPH2 gene were selected based on previous studies investigating associations between these SNPs and psychiatric or behavioral disorders. One hundred ninety-nine Caucasian women with IBS were included. Results of univariate analysis showed no association between TPH1and TPH2 gene SNPs and current level of psychological distress or psychiatric illness. However, TPH1 gene SNPs were associated with IBS-related cognitions (rs4537731 and rs21105) and quality of life (rs684302 and rs1800532), in particular the mental health and energy subscales. These associations were independent of the subjects’ levels of gastrointestinal symptoms. These results suggest that patients’ perception of their illness, and of the impact it has on their lives, may be subject to genetic influences, in this case sequence variants in TPH1. However, caution should be used in interpreting these results given the large number of hypothesis tests performed in this exploratory hypothesis-generating study, and the results should be considered tentative until confirmed in an independent sample.

AbstractGastrointestinal symptoms are frequent in acute adrenal insufficiency. Although digestive symptoms can significantly reduce quality of life, they are rarely described in patients with treated chronic adrenal insufficiency (CAI). We aimed to characterize digestive symptoms in CAI patients. We used the section pertaining functional bowel disorders of the Rome IV questionnaire. A questionnaire was published on the website of the non-profit patient association “Adrenals” (NPPA of CAI patients) for five months. Information on demographics, characteristics of adrenal insufficiency, digestive symptoms and quality of life was collected. The relatives of CAI patients served as a control group. We analyzed responses of 33 control subjects and 119 patients (68 primary adrenal insufficiency (PAI), 30 secondary adrenal insufficiency (SAI) and 21 congenital adrenal hyperplasia (CAH)). Abdominal pain at least once a week over the past 3 months was reported by 40%, 47% and 33% of patients with PAI, SAI and CAH respectively versus 15% for the controls (p = 0.01). Symptoms were consistent with the Rome IV criteria for irritable bowel syndrome in 27%, 33% and 33% of patients respectively versus 6% for the controls (p < 0.0001). Quality of life was described as poor or very poor in 35%, 57% and 24% of patients respectively versus 5% for the controls (p < 0.0001). In conclusion, digestive symptoms are frequent and incapacitating in CAI patients and similar to symptoms of irritable bowel syndrome in 30% of CAI patients. Assessment and management of digestive symptoms should be considered a priority for physicians treating patients with CAI.

Background & Aims: Irritable bowel syndrome (IBS) is a chronic and disabling gastrointestinal disorder. Although considerable research has underlined the influence of coping mechanisms as the determinants of the quality of life (QOL), only limited data are available regarding the specific coping mechanisms used by IBS patients to manage illness in daily life. Irrational cognitions are known to emerge in stressful situations such as chronic diseases, and it has been proposed to have implications in the QOL. The aim of this study was to explore the relationship between coping styles and irrational beliefs in predicting the effects of IBS symptoms on the health-related QOL (HRQOL).Methods: A cross-sectional study was performed at two tertiary gastroenterology centers. A sample of 70 consecutive IBS patients and 55 healthy controls was studied. All participants completed the Brief Cope Inventory, the Dysfunctional Attitudes Scale, the Short-Form Health Survey and a demographic questionnaire.Results: All the HRQOL scores of the group with IBS were significantly lower than the HRQOL scores of the healthy group [Pillai's trace V = 0.404, F(8, 116) = 9.833, p < 0.001]. Irritable bowel syndrome patients used more problem-focused coping and avoidant-oriented coping than healthy subjects. The impact of IBS symptoms on HRQOL distress is mediated by irrational beliefs and avoidant oriented coping.Conclusions: Our findings highlight the role of irrational cognition and coping mechanisms in patients with IBS. The results underline the importance of the evaluation of psychological aspects of IBS with the possibility of having more tailored treatments for these patients.

Functional Gastrointestinal Disorders are defined as chronic or recurrent gastrointestinal symptoms characterized by abdominal pain, constipation and/or diarrhoea (Tally, 1994; University of North Carolina, 1998). These disorders are of concern because of their high incidence, associated morbidity, expense and the impact of these disorders on people's quality of life. Drossman (1993, in University of North Carolina (UNC), 1998) found that of 5 400 U.S. households, 69% of people met the criteria for at least one of the functional gastrointestinal disorders which represents a 59% increase in the incidence of functional gastrointestinal disorders since 1983 (Drossman, in UNC, 1998; Drossman, 1983). In particular, Irritable Bowel Syndrome (IBS) sufferers account for 2,4 - 3,5 million visits to doctors annually. Furthermore, IBS sufferers spend $40 million annually on treatment for their condition. They also tend to have 3 to 4 times more disability days than other workers, which illustrates the debilitating effect of this disorder (Drossman, in UNC, 1998). It is therefore necessary that the etiology of IBS be researched, as well as the course and management of this debilitating disease. The studies presented in this series aimed to improve the understanding of the multiple agents that influence the development and course of IBS.

To evaluate the effectiveness of a low FODMAP (fermentable oligosaccharides, monosaccharaides, disaccharides and polyols) diet in the relief of symptoms and an improvement of the quality of life in individuals with irritable bowel syndrome in comparison to a standard diet according to the British Dietetic Association’s guidelines. A non-randomized clinical trial of adult patients with IBS was compared two diet interventions. An assessment of symptoms, quality of life, and nutritional status was performed before and after the four-week mark of intervention. Individuals from the Low FODMAP Diet (LFD) group were evaluated on a third moment, after the controlled reintroduction of FODMAPs. A total of 70 individuals were divided in two groups: Low FODMAP Diet (LFD; n = 47) and Standard Diet (SD; n = 23). 57 individuals completed the four-week intervention (LFD; n = 39; SD; n = 18). At the completion of four weeks, the symptoms improved in both groups (LFD: p < 0.01; DC: p < 0.05) but LFD led to a higher relief (p < 0.05), primarily with respect to abdominal pain and diarrhoea. Quality of life improved significantly in both groups, with no significant differences between SD vs LFD (p > 0.05). In the LFD group, the relief of symptoms observed at the four-week mark remained constant after reintroduction of FODMAPs. Both interventions seem to be effective for the relief of symptoms and quality of life, however LFD had higher effectiveness in the former. The results with LFD suggest it can be a preferred approach in individuals with diarrhoeal profile.
