Relationships Between Abdominal Pain and Fatigue With Psychological Distress as a Mediator in Women With Irritable Bowel Syndrome.

ABSTRACT: Women with irritable bowel syndrome often report fatigue, along with abdominal pain and psychological distress (i.e., depression and anxiety). There is little information about the relationships among these symptoms. Using a secondary data analysis (N = 356), we examined the relationship between abdominal pain and fatigue and whether psychological distress mediates the effect of abdominal pain on fatigue in both across women and within woman with irritable bowel syndrome. Data gathered through a 28-day diary were analyzed with linear regressions. The across-women and within-woman relationships among same-day abdominal pain, fatigue, and psychological distress were examined. Within-woman relationships were also examined for directionality among symptoms (i.e., prior-day abdominal pain predicts next-day fatigue and prior-day fatigue predicts next-day abdominal pain). In across-women and within-woman analyses on the same day, abdominal pain and fatigue were positively correlated. In within-woman analyses, abdominal pain predicted next-day fatigue, but fatigue did not predict next-day pain. In across-women and within-woman analyses, psychological distress partially mediated the effects of abdominal pain on fatigue. Symptom management incorporating strategies to decrease both abdominal pain and psychological distress are likely to reduce fatigue. Nursing interventions, such as self-management skills to reduce abdominal pain and psychological distress, may have the added benefit of reducing fatigue in irritable bowel syndrome.

Project description:ObjectiveIrritable bowel syndrome (IBS) is associated with alterations along the brain-gut-microbiota axis. Previous studies have suggested a parallel segregation of microbial features and psychological burden in IBS. This study aimed at exploring the microbial correlates of psychological distress in patients with IBS.MethodsForty-eight patients with IBS (Rome III criteria, M (SD) age = 42 (15) years, 35 female, 25 diarrhea-dominant, 5 constipation-dominant, and 18 alternating-type IBS) were assessed for psychological and clinical variables with validated questionnaires, fecal samples underwent microbial 16S rRNA analyses (regions V1-2). Microbial analyses comprised examination of alpha and beta diversity, correlational analyses of bacterial abundance and comparisons among subgroups defined by thresholds of psychological and IBS symptom variables, and machine learning to identify bacterial patterns corresponding with psychological distress.ResultsThirty-one patients (65%) showed elevated psychological distress, 22 (31%) anxiety, and 10 depression (21%). Microbial beta diversity was significantly associated with distress and depression (q = .036 each, q values are p values false discovery rate-corrected for multiple testing). Depression was negatively associated with Lachnospiraceae abundance (Spearman's ρ = -0.58, q = .018). Patients exceeding thresholds of distress, anxiety, depression, and stress perception showed significantly higher abundances of Proteobacteria (q = .020-.036). Patients with anxiety were characterized by elevated Bacteroidaceae (q = .036). A signature of 148 unclassified species accounting for 3.9% of total bacterial abundance co-varied systematically with the presence of psychological distress.ConclusionsPsychological variables significantly segregated gut microbial features, underscoring the role of brain-gut-microbiota interaction in IBS. A microbial signature corresponding with psychological distress was identified.Clinical trial registrationClinicalTrials.gov identifier NCT02536131, retrospectively registered.

Project description:Study objectivesSleep deficiency, psychological distress, daytime dysfunction, and abdominal pain are common in adults with irritable bowel syndrome. Prior research on individuals with chronic pain has identified the indirect effect of sleep on pain through psychological distress or daytime dysfunction; however, this effect is less clear in irritable bowel syndrome. The purpose of this study was to examine potential indirect effects of sleep on abdominal pain symptoms simultaneously through psychological distress and daytime dysfunction in adults with irritable bowel syndrome.MethodsDaily symptoms of nighttime sleep complaints (sleep quality and refreshment), psychological distress, daytime dysfunction (fatigue, sleepiness, and difficulty concentrating), and abdominal pain were collected in baseline assessments from 2 randomized controlled trials of 332 adults (mean age 42 years and 85% female) with irritable bowel syndrome. Structural equation modeling was used to examine the global relationships among nighttime sleep complaints, psychological distress, daytime dysfunction, and abdominal pain.ResultsThe structural equation modeling analyses found a strong indirect effect of poor sleep on abdominal pain via daytime dysfunction but not psychological distress. More than 95% of the total effect of nighttime sleep complaints on abdominal pain was indirect.ConclusionsThese findings suggest that the primary impact of nighttime sleep complaints on abdominal pain is indirect. The indirect effect appears primarily through daytime dysfunction. Such understanding provides a potential avenue to optimize personalized and hybrid behavioral interventions for adults with irritable bowel syndrome through addressing daytime dysfunction and sleep behaviors. Additional study integrating symptoms with biological markers is warranted to explore the underlying mechanisms accounting for these symptoms.Clinical trial registrationRegistry: ClinicalTrials.gov.
