The Effect of Mental Health, Neurological Disease, and Liver Disease on Quality of Life in Patients With Wilson Disease

Gandouling induces GSK3β promoter methylation to improve cognitive impairment in Wilson's disease

ETHNOPHARMACOLOGIC SIGNIFICANCE

Cognitive impairment is a serious clinical manifestation of Wilson's disease (WD) in the nervous system. Gandouling (GDL) is a hospital preparation of the First Affiliated Hospital of Anhui University of Chinese Medicine. Previous studies have found that GDL has an ameliorative effect on cognitive impairment in WD.

AIM OF THE STUDY

We aimed to explore the molecular-level regulatory mechanisms underlying cognitive impairment in WD, and provide evidence supporting GDL as a promising candidate drug for the treatment of cognitive impairment in WD. We found that GSK3β was significantly up-regulated in the brain tissue of C3He-Atp7Btx-J/J (tx-j) mice in the WD gene mutant model, and the monomer components of GDL could combine well with GSK3β. Therefore, in this work, we used Behavioral tests, Hematoxylin and eosin (H&E), Nissl and TUNEL staining, Ultrastructural morphological observation by Transmission electron microscopy (TEM), bisulfite sequencing (BSP), RT-qPCR, Western blot, immunofluorescence, network pharmacology, molecular docking, and related methods to study the effects of GDL in tx-j mice and HT22 cell to clarify the effect of GDL on cognitive impairment in WD.

RESULTS

In this study, MWM, NOR, H&E, Nissl TUNEL and TEM results showed that GDL could promote the repair of learning and memory function, improve the morphological damage to hippocampal neurons, and maintain mitochondria integrity. In the HT22 cell experiment, the CCK-8 method showed that GDL increased the viability of copper-overloaded cell models. The study found that GSK3β may be a target of GDL for the treatment of WD cognitive impairment through network pharmacology. Western blot and qRT-PCR results confirmed that GDL significantly increased the expression of proteins and mRNA in DNMT1, Nrf2, and HO-1. BSP showed that GSK3β promoter methylation was lower in the Wilson group than in the control group, and the promoter methylation of GSK3β was further reduced after intraperitoneal injection with decitabine, and GDL could ameliorate this pathology.

CONCLUSION

GDL demonstrates a protective role by inducing GSK3β promoter methylatio, activating the Nrf2/GSK3β signaling pathway in WD.

Burden of Wilson Disease among patients and care partners in the United States: results from a cross-sectional survey

OBJECTIVE

This study assessed the burden of Wilson Disease (WD) among patients and care partners (WD-CPs) in the US and compared it to a US general population of adults (GPs) and care partners (GP-CPs).

METHODS

This cross-sectional, self-reported survey included patients with WD and WD-CPs aged ≥18 years recruited through the Wilson Disease Association (WDA), while data for GPs and GP-CPs were obtained from the 2022 National Health and Wellness Survey. GPs and GP-CPs were propensity score matched (3:1) with WD patients and WD-CPs for demographics and health characteristics. Bivariate analysis evaluated differences in comorbidity burden and health-related outcomes of the WD cohorts compared to matched GP cohorts.

RESULTS

Thirty-seven patients with WD and 53 WD-CPs completed the survey. Most patients reported some treatment burden (73.3%), experienced sleep problems (60%), and visited a healthcare provider (HCP) in the past 6 months (91.9%). Compared with matched GPs, patients with WD had a significantly higher mortality risk (p < .001) and reported greater rates of chronic liver disease, cirrhosis (both, p < .001), migraines (p = .032), non-alcoholic steatohepatitis (p = .004), sleep problems (p = .009) and HCP visits (p = .002). Most WD-CPs (75.5%) reported high burden of caring (mean ZBI-12 score, 26.5) and more negative impact on esteem than GP-CPs.

CONCLUSION

This study highlights the burden of WD experienced by patients and WD-CPs, with patients experiencing high treatment burden, comorbidity burden and healthcare resource utilization, and WD-CPs experiencing high impact of caring, including impact on employment and self-esteem.

Health-Related Quality of Life in Patients Living with Wilson Disease in Spain: A Cross-Sectional Observational Study

Wilson disease (WD) is a rare copper metabolism disorder caused by mutations in the ATP7B gene. It usually affects young individuals and can produce hepatic and/or neurological involvement, potentially affecting health-related quality of life (HRQoL). We assessed HRQoL in a cohort of Spanish patients with WD and evaluated disease impact on several domains of patients' lives, treatment adherence, drug preference and satisfaction, and healthcare resource utilisation in a cross-sectional, retrospective, multicentric, observational study. A total of 102 patients were included: 81.4% presented isolated liver involvement (group H) and 18.6% presented neurological or mixed involvement (group EH). Up to 30% of patients reported a deteriorated emotional status with anxiety and depression, which was greater in the EH subgroup; the use of neuropsychiatric drugs was high. Over 70% of the patients were satisfied with their current treatment but complained about taking too many pills, stating they would consider switching to another more patient-friendly treatment if available. The Simplified Medication Adherence Questionnaire revealed only 22.5% of patients were fully adherent to therapy, suggesting that alternative therapies are needed. This real-world study, even though is highly enriched with hepatic patients and mild disease, shows that WD impacts patients' HRQoL, especially in the emotional domain.

Quality of life and depression in Wilson's disease: a large prospective cross-sectional study

BACKGROUND

Wilson's disease (WD) is an autosomal recessive genetic disorder due to a mutation of the ATP7B gene, resulting in impaired hepatic copper excretion and accumulation in various tissues. Lifelong decoppering treatments are the keystone of the treatment. These treatments can prevent, stabilize, or reverse the symptoms making WD a chronic disease. Quality of life (QoL) is one of the best outcome measures of any therapeutic intervention in chronic diseases but has not been evaluated in large cohorts of WD patients.

METHOD

To better evaluate the QoL in WD and the correlation with different clinical or demographic factors we have performed a prospective cross-sectional study.

RESULTS

Two hundred fifty-seven patients (53.3% men, mean age of 39.3 years and median disease duration of 18.8 years) were included between 1st January 2021 and 31st December 2021. Hepatoneurological form of the disease and depression were significantly correlated with low QoL (p < 0.001 for both). However, the patients' quality of life was similar to that of the general population, and only 29 patients (11.3%) had moderate to severe depression.

CONCLUSIONS

Neurological patients should be closely monitored to prevent and treat symptoms of depression that impact their quality of life.

BMI Modifies the Association Between Depression Symptoms and Serum Copper Levels

Depression is one of the most common mental disorders which dramatically threatens public health and wellness. Copper has been known to be involved in many biological processes that could help explaining the occurrence of depression. However, studies focusing on its effect have yielded mixed results. The present study aims to evaluate the association between serum copper levels and depression symptoms. It also investigates the effect of modification of BMI (body mass index) on depression symptoms. A total of 5419 US adults aged 20 years or older from the National Health and Nutrition Examination Survey (NHANES) 2011-2016 participated in the cross-sectional study. Logistic regression models were applied using depression levels as the outcome and serum cooper/selenium/zinc categories as the main predictor, with the adjustments of gender, age, marital status, race, education, family income level, alcohol drinking, cigarette smoking, diabetes, pressure, stroke, and BMI. The interaction terms for copper levels and other covariates were further incorporated into the model to assess their roles in predicting depression symptoms. The prevalence of depression symptoms was significantly higher in samples with a high copper level. Among the levels of serum copper, selenium, and zinc, only the association between depression symptoms and serum copper levels was observed to be significant in the unadjusted model (P = 0.002). Individuals with a high copper level (114-134 μg/dL) and a very high copper level (≥ 134 μg/dL) had 1.85 (95% CI 1.24, 2.77)- and 1.72 (95% CI 1.21, 2.44)-fold higher odds ratio of depression symptoms, respectively, compared to those with a normal serum copper level. Although the association was not significant in the adjusted models, in which confounders were added, the interaction of copper level, including high and very high copper levels, and obesity (BMI ≥ 30 kg/m²) exhibited significantly higher odds ratio (4.12 (95% CI 1.38, 12.27) and 4.53 (95% CI 1.87, 10.96)) of having depression symptoms. The concentration of serum copper was positively associated with the prevalence of depression symptoms. Obesity exacerbated the risk of having depression symptoms in people with high serum copper levels.

Wilson disease in Northern Portugal: a long-term follow-up study

Introduction

Wilson disease is an autosomal recessive disease of liver copper metabolism with predominant hepatic and neurological manifestations. Long-term data on the clinical follow-up and treatment efficacy are limited due to the low frequency of the disease. We evaluated a large cohort of Wilson disease patients from Northern Portugal during a 20-year follow-up period.

Methods

Twenty-four patients, diagnosed from 1975 to 2020 in a tertiary care center in Portugal, were retrospectively evaluated according to their clinical presentation, therapies and outcomes.

Results

Most of the patients were males (54%), with a median age at diagnosis of 19 years old (interquartile range 15–25). The main manifestations of Wilson disease were hepatic (71%) and neurological (25%). Family history was positive in 5 (21%) patients. Four patients (17%) presented with acute liver failure and fifteen (63%) individuals had cirrhosis at diagnosis. Penicillamine therapy was used by 11 (46%) patients, while trientine and zinc were given to 8 (33%) and 1 (4%) patient, respectively. Ten (42%) individuals underwent liver transplantation. The majority of patients (83%) had stable disease or improved outcomes during follow-up.

Conclusion

This is the largest cohort of adult patients with Wilson disease reported in Northern Portugal. We show that Wilson disease has favorable outcomes with long overall survival, assuming adherence to therapy and lack of other insults to their liver.
