The Interplay of Biopsychosocial Factors and Quality of Life in Inflammatory Bowel Diseases: A Network Analysis

The Relationship Between Loneliness, Social Isolation, and Inflammatory Bowel Disease: A Narrative Review

BACKGROUND

There is clear evidence that loneliness and social isolation have profound health consequences. Documenting the associations of loneliness and social isolation with inflammatory bowel disease (IBD) symptoms, disease severity, and treatment outcomes could meaningfully improve health and quality of life in patients with IBD.

PURPOSE

The purpose of this narrative review was to synthesize the empirical evidence on the associations of loneliness and social isolation with IBD symptoms, disease severity, and treatment outcomes.

METHODS

Articles were identified through systematic database searches. Quantitative studies that enrolled patients with IBD were included if they examined one of the following outcomes: (a) loneliness or social isolation or (b) IBD-related symptoms, disease severity, or treatment outcomes.

RESULTS

We identified 1,816 articles after removing duplicates. Of the 18 studies that met the inclusion criteria, 15 were cross-sectional and 3 were longitudinal. Overall, studies found that loneliness was associated with greater disease activity, functional gastrointestinal symptoms, IBD illness stigma, depressive symptoms, daily IBD symptom burden, reduced resilience, and poorer quality of life. Social isolation was associated with higher prevalence of IBD hospitalizations, premature mortality, and depression.

CONCLUSIONS

Findings suggest that loneliness and social isolation are associated with poorer health and quality of life in patients with IBD. Prospective cohort studies examining the biobehavioral mechanisms accounting for the associations of loneliness and social isolation with IBD-related outcomes are needed to guide the development of psychological interventions for individuals living with IBD.

Associations Between Brain Morphology, Inflammatory Markers, and Symptoms of Fatigue, Depression, or Anxiety in Active and Remitted Crohn's Disease

BACKGROUND

Fatigue and psychosocial impairments are highly prevalent in IBD, particularly during active disease. Disturbed brain-gut interactions may contribute to these symptoms. This study examined associations between brain structure, faecal calprotectin, and symptoms of fatigue, depression, and anxiety in persons with Crohn's disease [CD] in different disease states.

METHODS

In this prospective observational study, n = 109 participants [n = 67 persons with CD, n = 42 healthy controls] underwent cranial magnetic resonance imaging, provided stool samples for analysis of faecal calprotectin, and completed questionnaires to assess symptoms of fatigue, depression, and anxiety. We analysed differences in grey matter volume [GMV] between patients and controls, and associations between regional GMV alterations, neuropsychiatric symptoms, and faecal calprotectin.

RESULTS

Symptoms of fatigue, depression, and anxiety were increased in patients with CD compared with controls, with highest scores in active CD. Patients exhibited regionally reduced GMV in cortical and subcortical sensorimotor regions, occipitotemporal and medial frontal areas. Regional GMV differences showed a significant negative association with fatigue, but not with depression or anxiety. Subgroup analyses revealed symptom-GMV associations for fatigue in remitted but not in active CD, whereas fatigue was positively associated with faecal calprotectin in active but not in remitted disease.

CONCLUSION

Our findings support disturbed brain-gut interactions in CD which may be particularly relevant for fatigue during remitted disease. Reduced GMV in the precentral gyrus and other sensorimotor areas could reflect key contributions to fatigue pathophysiology in CD. A sensorimotor model of fatigue in CD could also pave the way for novel treatment approaches.

Flourishing in life in patients with Inflammatory Bowel Disease: The role of illness identity and health-related quality of life

Amidst chronic challenges in Inflammatory Bowel Disease (IBD), including physical symptoms, emotional stress, and social constraints, this study aimed to elucidate how patients' perceptions of their illness and its integration into their self-concept are related to their ability to flourish in life. We hypothesized that having a positive and integrative illness identity and social identification will predict higher flourishing, mediated by enhanced health-related quality of life (HRQoL). In an online survey with 244 German-speaking IBD adults (Mage = 36.62, 85% women), we found that lower engulfment (where the disease dominates one's identity) predicted higher levels of flourishing, mediated by higher HRQoL. Enrichment, reflecting personal growth from illness, directly predicted higher flourishing, while stronger social identification predicted higher subjective well-being, but not flourishing. The results highlight the potential of fostering positive illness identities and social connections to enhance flourishing in individuals with IBD or similar chronic conditions.

A Systematic Review of Relationships Between Illness Identity and Health-Related Outcomes in Individuals with Chronic Illnesses

The aim of the current systematic review is to examine relationships among illness identity and illness-specific variables, adherence, and health-related outcomes. Studies were included if they (a) presented quantitative data on illness identity's relationship with adherence or health-related outcomes, (b) included chronic medical illness samples, (c) were peer-reviewed, and (d) were available in English. PubMed and EBSCOhost were searched. Quality was evaluated using the EPHPP Tool. Twelve papers were included. Moderate evidence supports the relationship between engulfment, enrichment, and illness complexity. Moderate evidence supports relationships between multiple identities and adherence as well as with various health-related outcomes. There is somewhat consistent evidence for associations between engulfment and negative health-related outcomes. It may be important to inform healthcare providers of possible identity challenges that patients face and their associations with adherence and health-related outcomes. Routine illness identity screening may allow for identification of individuals who would benefit from increased support.

Depression and active disease are the major risk factors for fatigue and sleep disturbance in inflammatory bowel disease with consequent poor quality of life: Analysis of the interplay between psychosocial factors from the developing world

BACKGROUND AND OBJECTIVES

The prevalence and risk factors of fatigue and sleep disturbances in inflammatory bowel disease (IBD) patients and their impact on the quality of life (QOL) are largely underreported in the developing world, where IBD is on the rise.

METHODS

Consecutive patients attending the IBD clinic were interviewed between November 2021 and March 2022 using an assisted questionnaire (English, Hindi and Telugu versions)(including demographics, disease activity, QOL, IBD fatigue score [IBD-F], Hospital anxiety and depression score: [HADS], Pittsburg Sleep Quality Index: [PSQI]). Logistic regression was used to identify risk factors of fatigue and sleep disturbance. A correlational analysis between mental health factors and QOL was performed.

RESULTS

AS many as 202 IBD patients (age 18-78 [median 31] years, 65.8% male) completed the questionnaires. Fatigue and sleep disturbances were highly prevalent (55.9% and 53.4%, respectively). On multi-variate analysis, depression (p = 0.008, odds ratio [OR] -1.38, 95% confidence interval [CI] -1.09-1.75), active disease (p = 0.001,OR-8.81,95% CI- 2.49-31.23) and poor sleep (p = 0.009, OR-1.17, 95% CI:1.04-1.31) were predictive of fatigue, whereas depression (p < 0.001,OR-1.32,95% CI-1.19-1.46) and active disease (p < 0.001,OR-6.77, 95% CI-2.67-17.17) were predictive of sleep disturbance. On sub-group analysis, poor sleep quality and lack of renumeration predicted fatigue, whereas old age and female gender predicted poor sleep quality in Crohn's disease (CD). QOL (Short IBD questionnaire: [SIBDQ]) scores had a strong and moderate negative correlation with IBD-F (r = -0.735, p < 0.0001) and PSQI (r = -0.682, p < 0.001) scores, respectively. The results should be interpreted in the context of lack of validated translated questionnaires in all native languages in a multilingual country. Translational assistance was provided to overcome the limitation.

CONCLUSION

Fatigue and sleep disturbances are highly prevalent in Indian IBD patients. Apart from modulation of disease activity, screening those with mental health illness may help improve fatigue/sleep quality and overall QOL.

Fatigue, Physical Activity, and Quality of Life in Patients with Inflammatory Bowel Disease: A Cross-Sectional Study

Purpose

The benefits of physical activity (PA) are widely recognized, but the intensity of PA in inflammatory bowel disease (IBD) patients with varying disease activity levels remains controversial. We aimed to investigate the relationship between PA levels, fatigue, and other health-related quality of life (QoL) in Chinese IBD patients.

Patients and Methods

The study is a cross-sectional investigation conducted at a comprehensive IBD diagnosis and treatment facility in East China, spanning from August 2022 to February 2023. A total of 245 participants were initially enrolled, and after excluding individuals with incomplete data about crucial exposure and outcome variables, the final sample size amounted to 237. Participants were provided with a questionnaire encompassing sociodemographic factors, clinical information, the International Physical Activity Questionnaire (IPAQ), the Multidimensional Fatigue Inventory (MFI-20), and the Inflammatory Bowel Disease Questionnaire (IBDQ). Correlation analysis was employed to assess the relationship between variables.

Results

A majority of participants (144) exhibited low levels of PA. Furthermore, 40.5% of all participants reported experiencing fatigue. Individuals with low levels of PA had an average MIF-20 score of 62.9±16.0. Correlation analysis showed that PA was significantly and negatively associated with fatigue (r = -0.224, p < 0.001). Additionally, PA was also negatively correlated with anxiety (r = -0.150, p < 0.05) and depression (r = -0.242, p < 0.001). On the other hand, PA was positively correlated with quality of life (QoL) (r = 0.171, p < 0.01). Furthermore, our analysis indicated that sleep disorders were positively associated with both anxiety (r = 0.349, p < 0.01) and depression (r = 0.354, p < 0.001).

Conclusion

The levels of PA are significantly low, and there is a high prevalence of fatigue among individuals with IBD. PA in IBD showed a strong negative correlation with fatigue and a strong positive correlation with quality of life.

Validation of the German version of the Short Health Scale - a brief, valid and reliable instrument to assess health-related quality of life in German-speaking patients with inflammatory bowel diseases

BACKGROUND

Health-related quality of life (hrQoL) may be the most important patient-reported outcome for patients with chronic disorders. The Short Health Scale (SHS) is a brief four-item instrument to assess hrQoL in patients with bowel disorders. This study examined the validity, reliability and sensitivity of the German translation of the SHS in a cohort of outpatients with inflammatory bowel diseases (IBD).

METHODS

The study was preregistered in April 2021 (https://doi.org/10.17605/OSF.IO/S82D9). Outpatients with IBD (n=225) in different stages of disease activity (as determined by the Harvey-Bradshaw index or partial Mayo score) completed the German SHS and the short Inflammatory Bowel Disease Questionnaire (sIBDQ) as an established measure of hrQoL to examine the convergent validity. To assess reliability, a subset of patients (n=30) in remission completed the same questionnaires after 4-8 weeks. Sensitivity to change was established from questionnaires of patients with either decreased (n=15) or increased (n=16) disease activity after 3-6 months.

RESULTS

The internal consistency of the German SHS was high (Cronbach's α=0.860). SHS total scores correlated strongly with sIBDQ scores (ρ=-0.760, p<0.001) and disease activity (ρ=0.590, p<0.001). Retest reliability was high (ρ=0.695, p<0.001). Sensitivity to change was statistically significant for patients with decreased (p=0.013) but not increased (p=0.134) disease activity.

CONCLUSION

The German version of the SHS is a valid and reliable tool to measure hrQoL in persons with IBD.
