Cross-Cultural Adaptation and Psychometric Assessment of the Liver Disease Symptom Index 2.0 to Measure Health-Related Quality of Life Among Iranian Patients With Chronic Hepatitis B

Liver disease symptoms are associated with higher risk of adverse clinical outcomes: A longitudinal study of North American adults with chronic Hepatitis B

Background

Symptoms of chronic hepatitis B (CHB) are not well characterized.

Aims

To evaluate CHB symptoms and associations with disease activity and clinical outcomes.

Methods

Longitudinal data from 1,576 participants in the Hepatitis B Research Network Cohort Study who completed symptom assessments were analyzed. A composite symptom score was calculated using a Symptom Checklist (0=none to 40=extreme). Multivariable mixed models assessed variables associated with symptom change over time. Latent class symptom trajectories were evaluated. The cumulative probability of long-term clinical outcomes (new onset cirrhosis, hepatic decompensation, hepatocellular carcinoma, liver transplantation, death) was examined by baseline symptom groups.

Results

Participants median age was 42 (range:18-80), 51% were male, 75% Asian, (68% of whom were born outside North America) with a median follow-up of 4.2 years. On average, symptoms did not significantly change over time. The multivariable model identified several variables associated with higher symptoms during follow-up: being female, non-Asian, born in the US/Canada, lower education, higher AST, lower platelets, and more comorbidities. Two patient subgroups were identified based on longitudinal symptom trajectories: a low symptom group (92%, n=1,451) with symptom scores averaging 2.4 over time and a moderate symptom group (8%, n=125) with symptom scores averaging 11.5. During follow-up, 7.3% in the moderate symptom group, but only 3.2% of the low symptom group, developed adverse outcomes (p=0.02).

Conclusions

In this large cohort of CHB patients, symptoms were generally mild and stable over time. However, in some patients with moderate symptoms at baseline, deleterious clinical outcomes were more frequent in follow-up.

Curcumin ameliorates health-related quality of life in patients with liver cirrhosis: A randomized, double-blind placebo-controlled trial

OBJECTIVES

Current study aimed to find the effects of curcumin on quality of life (QoL) in liver cirrhotic patients.

DESIGN

In this randomized double-masked placebo-controlled trial, 70 cases with liver cirrhosis aged 20-70 years were randomly divided into two groups to receive 1000 mg/day curcumin (n = 35) or placebo (n = 35) for 12 weeks. The health-related QoL (HRQoL) was assessed by CLDQ, LDSI 2.0, and SF-36.

RESULTS

Fifty-eight patients (28 in curcumin and 30 in placebo groups) finished the research. Compared with baseline, overall scores as well as most of CLDQ domains (e.g. Fatigue, Emotional Function, Worry, Abdominal Symptoms, and Systemic Symptoms) and the Physical and Mental health (Total) scores and most of SF-36 domains (e.g. Physical Functioning, Bodily Pain, Vitality, Social Functioning, and Mental Health) increased considerably (P < 0.05) after curcumin administration. Furthermore, curcumin reduced most of LDSI 2.0 domains (e.g. Itch, Joint pain, Pain in the right upper abdomen, Sleeping during the day, Decreased appetite, Depression, Fear of complication, Jaundice, Hindrance in Financial Affairs, Change in use of time, Decreased sexual interest, and Decreased sexual activity) significantly (P < 0.05). Significant differences were noticed between two groups in CLDQ domains and overall scores, LDSI 2.0 domains and overall scores, SF-36 Physical and Mental health (total) scores and all its domains scores (P < 0.05), adjusting for baseline values and disease duration.

CONCLUSIONS

Curcumin improved QoL in liver cirrhotic patients according to CLDQ, LDSI 2.0, and SF-36 domains. Additional studies are warranted to consider curcumin as a safe, accessible, and low-cost complementary therapeutic option in cirrhosis.

Patient-reported outcomes in a large North American cohort living with chronic hepatitis B virus: a cross-sectional analysis

BACKGROUND

Patient-reported outcomes (PROs) such as health-related quality of life (HRQoL) and symptoms associated with chronic hepatitis B viral (HBV) infection have not been well-described in North American cohorts.

AIMS

To evaluate several PROs and associations with HBV disease activity markers.

METHODS

Cross-sectional analysis including 876 adults who completed PRO measures during the Hepatitis B Research Network Adult Cohort Study. Participants on HBV treatment were excluded. Outcomes included: HRQoL using the SF-36 mental component summary and physical component summary scores; symptom burden using a 10-item Total Symptom Checklist and fatigue using an instrument from the Patient-Reported Outcomes Measurement Information System®. Covariates included laboratory markers of disease severity, virological status, comorbidities and medications.

RESULTS

Median age was 42 (range: 19-79), 51% were female, 73% Asian, 19% HBeAg (+), 2% had AST-platelet ratio index (APRI) ≥1.5 and 74% without comorbidities. Mean mental component summary T-score = 52, physical component summary T-score = 54 and PROMIS Fatigue T-score = 47. On a scale from 0 (none) to 40 (extreme), the mean Symptom Checklist score = 3 and 25% reported no symptoms. The most frequent symptoms were fatigue (60%), irritability (32%) and itching (32%). Most symptoms were 'a little bit' bothersome. In multivariable regressions, APRI ≥1.50 and more comorbidities were associated with worse patient-reported outcomes; virological markers were not. Adding the Total Symptom Checklist score to original regression models increased explanation of variation in the mental component summary score from 4% to 44% and the Physical Component Summary Score from 17% to 34%.

CONCLUSIONS

Untreated North American HBV patients with mild liver disease report favourable health-related quality of life and minimal symptoms. HBV does not impact health-related quality of life unless advanced liver disease or comorbidities are present. High symptom burden explains substantial variation in health-related quality of life.

Development and initial validation of the chronic hepatitis B quality of life instrument (CHBQOL) among Chinese patients

PURPOSE

This study developed and tested preliminary measurement properties of a Chinese scale specifically designed to measure HRQOL in patients with chronic hepatitis B (CHBQOL).

METHODS

We conducted 94 individual interviews with CHB patients to solicit items and five hepatitis expert interviews along with three rounds of cognitive interviews to identify problems with relevance and understanding of content. A cross-sectional validation study was then conducted to evaluate measurement properties (n = 578). Factor analysis was used to determine the latent structure of the scale. Reliability was evaluated through Cronbach's alpha coefficients and intra-class correlation coefficients (ICCs). Measurement model adequacy, convergent, discriminant, and known-groups validity were also examined.

RESULTS

A scale of 30 items was drafted. After item reduction, the remaining 23 items were assigned to the CHBQOL Somatic symptoms, Emotional symptoms, Belief and Social stigma domains, which had acceptable goodness of fit (χ²/df = 3.13, GFI = 0.90, AGFI = 0.88, RMSEA = 0.06, SRMR = 0.05). All the CHBQOL domains had satisfactory reliability with Cronbach's α coefficients ranging from 0.73 to 0.91 and ICCs were higher than 0.70 except for Belief domain (ICC = 0.54). Convergent and discriminant validity were acceptable as supported by significant item-domain correlations (0.64-0.90). In general, the correlations between CHBQOL and the SF-36 dimensions met hypotheses. Significant differences were found by mean scores in the subgroups of demographic and clinical variables, supporting the known-groups validity.

CONCLUSIONS

The CHBQOL instrument proved to be an appropriate tool for assessing HRQOL among Chinese CHB patients.

An Electronic Questionnaire for Liver Assessment in Congenital Disorders of Glycosylation (LeQCDG): A Patient-Centered Study

Congenital disorders of glycosylation (CDG) are ultra-rare diseases showing a great phenotypic diversity ranging from mono- to multi-organ/multisystem involvement. Liver involvement, mostly nonprogressive, is often reported in CDG patients. The main objectives of this work were (1) to better understand liver involvement in CDG patients through a liver electronic questionnaire targeting CDG families (LeQCDG) and (2) to compare responses from LeQCDG participants with literature review regarding the prevalence of liver disease and the occurrence of liver symptoms in CDG patients. The network of patient advocacy groups, families and professionals (CDG & Allies - PPAIN) developed the LeQCDG by adapting validated published questionnaires. The LeQCDG was approved by an ethics committee, and the recruitment of patients and caregivers proceeded through social media platforms. Participants were asked to report past or present liver-related symptoms (e.g. hepatomegaly, liver fibrosis and cirrhosis) and laboratory results (e.g. biochemical and/or radiological). From 11 December 2016 to 22 January 2017, 155 questionnaires were completed. Liver disease was present in 29.9% of CDG patients. Main symptoms reported included hepatomegaly, increased levels of serum transaminases, fibrosis, steatosis and cirrhosis. The data obtained in this online survey confirm findings from a recent literature review of 25 years of published evidence (r = 0.927, P = 0.02). Our questionnaire collected large amounts of meaningful, clinical and patient-oriented data in a short period of time without geographic limitations. Internet-based approaches are especially relevant in the context of ultra-rare diseases such as CDG.
