Anxiety and Depression in Patients with Primary Biliary Cholangitis: Current Insights and Impact on Quality of Life

An online mind-body program improves mental health and quality of life in primary biliary cholangitis: A randomized controlled trial

BACKGROUND AND AIMS

People with primary biliary cholangitis (PBC) experience high rates of mental distress and fatigue despite standard of care therapy. We aimed to assess the impact of an online mind-body intervention on these symptoms.

METHODS

This 12-week RCT used sequential mixed-methods evaluation. Alongside standard of care, participants with primary biliary cholangitis were randomized to receive weekly countdown emails, or the intervention consisting of (i) a weekly 20-30 minute-mind-body follow-along video, (ii) weekly 5-10-minute psychology-based "managing chronic disease skills videos," and (iii) 10-minute telephone check-ins. The primary outcome was a change in the Hospital Anxiety and Depression Scale (HADS). Secondary outcomes evaluated changes in fatigue, perceived stress, resilience, and health-related quality of life. ANCOVA determined between-group differences.

RESULTS

Of the 87 randomized patients (control group: n = 44, intervention group: n = 43), the between-group HADS total score improved by 20.0% (95% CI 4.7, 35.2, p = 0.011). Significant improvements were seen in depression (25.8%), perceived stress (15.2%), and 2 primary biliary cholangitis-40 domains [emotional symptoms (16.3%) and social symptoms (11.8%)] with a mean satisfaction of 82/100. This corresponded with end-of-study qualitative findings. Although no improvements were observed in fatigue in the main analysis, a significant benefit was observed in the subgroup of intervention participants (20/36;56%) who completed the mind-body video routine at least 3 times per week.

CONCLUSION

This intervention improved measures of mental wellness and quality of life with high satisfaction and reasonable adherence. Future studies could explore strategies to optimize adherence and target fatigue.

The feasibility and acceptability of an online mind-body wellness program for patients with primary biliary cholangitis

Background

Persons with primary biliary cholangitis (PBC) experience significantly higher rates of mental distress and impaired health related quality of life (HrQoL) than the general population. Given limited evidence, but a high need, our primary aim was to assess feasibility and acceptability of a 12-week, online, mind-body wellness program in people with PBC.

Methods

This was a single-group, sequential mixed-methods, pre-post feasibility, and acceptability study. Core program components included follow-along movement, meditation and breathwork videos, and cognitive behavioural therapy informed activities. This was supplemented by weekly phone check-ins. Feasibility was assessed by recruitment, adherence, and retention. The pre-post exploratory efficacy assessment included surveys for fatigue, perceived stress, anxiety, depression, HrQoL, and resilience. A qualitative descriptive approach with semi-structured interviews evaluated study experiences.

Results

Thirty-two participants were recruited within 30 days and 29 (91%) were retained to end-of-study. Of these, 25 (86%) adhered to carrying out the mind-body practice at least 2-3 days per week. Feedback supported acceptability (satisfaction score 90%). Significant improvements were observed in fatigue (13%, p = 0.004), anxiety (30%, p = 0.005), depression (28%, p = 0.004), and five PBC-40 domains (itch, fatigue, cognitive, emotional, general symptoms). Qualitative interviews revealed improved stress management, better coping, and a more positive mindset. Fatigue and self-sabotaging thoughts were cited as barriers to participation.

Conclusions

These findings suggest that a 12-week online mind-body intervention is feasible and acceptable in patients with PBC. After iterative refinement, a randomized controlled trial will be designed using this feedback.

Disease burden of primary biliary cholangitis and associated pruritus based on a cross-sectional US claims analysis

Objective

In order to identify areas of unmet need in patients with primary biliary cholangitis (PBC), this study sought to use real-world observational healthcare data to characterise the burden in patients with PBC and in PBC patients with a recorded diagnosis of pruritus.

Design

This retrospective, cross-sectional database study compared prevalence of prespecified comorbidities and medications in the PBC population and PBC-pruritus subpopulation with non-cases using an indirect standardisation approach. The PBC population was identified from the US IBM MarketScan Commercial Claims and Medicare Supplemental Database during 2016 using International Classification of Diseases 10th Revision, Clinical Modification codes (≥2 claims for PBC); the PBC-pruritus subpopulation additionally had ≥1 claim for pruritus during this period. Non-cases had no claims for PBC. Indirect age-sex standardised prevalence ratios (iSPR) and 95% confidence intervals (CIs) were calculated for prespecified comorbidities and medications recorded during 2017.

Results

The PBC population (N=1963) and PBC-pruritus subpopulation (N=139) had significantly higher prevalence of fatigue (19.9%, iSPR (95% CI): 1.51 (1.36 to 1.66); 26.6%, 2.10 (1.48 to 2.90)), depression/anxiety (21.3%, 1.09 (0.99 to 1.20); 28.1%, 1.46 (1.04 to 2.00)) and sleep-related issues (6.9%, 1.18 (0.99 to 1.40); 14.4%, 2.58 (1.58 to 3.99)) compared with non-cases. Bile acid sequestrants were prescribed in 5.8% and 18.0% of the PBC and PBC-pruritus populations, respectively. In general, a higher prevalence of comorbidities and medication use was observed in the PBC-pruritus subpopulation compared with the PBC population and non-cases.

Conclusion

Despite availability of treatments for PBC, the PBC population had a higher burden of comorbidities than non-cases. This burden was even greater among the PBC-pruritus subpopulation, with a particularly high prevalence of sleep disorders and depression/anxiety. Despite this, pruritus remains undertreated highlighting a need for treatments specifically indicated for cholestatic pruritus.
