Health-related quality of life in non-alcoholic fatty liver disease: A cross-cultural study between Spain and the United Kingdom

BACKGROUND

It is unclear what biopsychosocial factors influence the impact of NAFLD on health-related quality of life (HRQoL), and if these factors are equally important predictors between different nationalities.

METHODS

HRQoL (CLDQ) was measured in both Southern European (Spain, n = 513) and Northern European (United Kingdom -UK-, n = 224) cohorts of patients with NAFLD in this cross-sectional study. For each cohort, participant data were recorded on histological grade of steatohepatitis, stage of fibrosis and biopsychosocial variables. Regression analysis was used to explore which of these variables predicted HRQoL. Moderated mediation models were conducted using SPSS PROCESS v3.5 macro.

RESULTS

Participants with severe fibrosis reported more fatigue, systemic symptoms and worry, and lower HRQoL than those with none/mild fibrosis, regardless of place of origin. In addition, body mass index (BMI) and gender were found to be significant predictors of HRQoL in both Spanish and UK participants. Female gender was associated with worse emotional function, higher BMI and more fatigue, which predicted lower participants' HRQoL. UK participants showed more systemic symptoms and worry than Spanish participants, regardless of liver severity. The negative effects of gender on HRQoL through emotional function, BMI and fatigue were reported to a greater degree in UK than in Spanish participants.

CONCLUSIONS

UK participants showed a greater impairment in HRQoL as compared to Spanish participants. Higher fibrosis stage predicted lower HRQoL, mainly in the Spanish cohort. Factors such as female gender or higher BMI contributed to the impact on HRQoL in both cohorts of patients and should be considered in future multinational intervention studies in NAFLD.

Can reporting more lead to less? The role of metrics in assessing liver transplant program performance

Appropriate metrics for performance analysis is an active topic of debate within the transplant community. This study explores current proposals on metric expansion as well as potential metrics and prospective collaborations that have not received widespread discussion within the transplant community. The premature introduction of additional, nonvalidated metrics risks behaviors that may undermine donor utilization and patient access to transplantation.

From Death to Health in 30 Days: A Hemochromatosis Case Report

BACKGROUND

Heredity hemochromatosis (HH) is an underdiagnosed genetic disease that can lead to life-threatening multisystem organ failure. Identifying and treating HH early can prevent the progression of the disease.

CASE PRESENTATION

For a 60-year-old white patient without obvious symptoms, it was a revelation to discover that he had HH. This patient, although receiving evidence-based care, ultimately required a liver transplant. As his condition deteriorated, the plan for this patient and his family involved working within an interdisciplinary team that included nurse practitioners and intensive care unit nurses.

DISCUSSION

The uniqueness of this case illustrates the crucial role of a health care team that persisted in differentiating the patient's diagnosis and continued to sustain both physical and emotional care throughout his hospitalization despite a poor prognosis. The patient felt support from this team during the course of his illness, from requiring life-supporting care in intensive care unit to returning home and resuming his normal activities of daily living.

Impact of hepatitis C virus infection on health-related quality of life before and after liver transplantation: a multidisciplinary point of view

INTRODUCTION

Hepatitis C negatively changes patient quality of life even in the absence of advanced liver disease. The specific patterns of quality of life of hepatitis C positive patients waiting for transplant or after surgery are not widely studied. Areas covered: A significant percentage of infected patients show cognitive impairment, fatigue, and/or a 'brain fog', that cannot be explained by the liver disease. Depression can be diagnosed in one third of hepatitis C positive patients. Conflicting data are available regarding the possible role of Model for End-Stage Liver Disease score as predictor of impaired quality of life. In the first period after liver transplant, quality of life tends to increase at the pre-transplant period but in the medium and long-term period, it declines. The recurrence of hepatitis C infection represents a strong predictor of morbidity and mortality and can significantly affect the global quality of life of patients. Expert commentary: Hepatologists, surgeons and psychologists should collaborate to support infected patients in all phases of transplant including the long-term period after surgery. Education and information should be implemented especially regarding the positive role of new direct antivirals.

Value of HCC-MELD Score in Patients With Hepatocellular Carcinoma Undergoing Liver Transplantation

CONTEXT

Liver transplantation (LT) is considered the ideal therapy for patients with hepatocellular carcinoma (HCC) having cirrhosis but the shortage of liver donors and the risk of dropout from the wait list due to tumor progression severely limit transplantation. A new prognostic score, the HCC-model for end-stage liver disease (HCC-MELD), was developed by combining α-fetoprotein (AFP), MELD, and tumor size, to improve risk stratification of dropout in patients with HCC.

OBJECTIVES

In this study, we investigated the ability of the HCC-MELD score in predicting the posttransplant for patients fulfilling Milan criteria (MC).

DESIGN

Two hundred patients with stage II tumor were retrospectively reviewed from a total of 1290 transplants performed at our institution from October 1997 through April 2015. Cox regression analysis was performed to identify the prognostic factors impacting the posttransplant survival.

RESULTS

Overall survival at 1, 5, and 10 years was 89.3%, 71.1%, and 67.2%, whereas disease-free survival was 86.4%, 66.5%, and 52.4%, respectively. Multivariate analysis showed HCC-MELD score (hazard ratio [HR] 39.6, P < .001) and microvascular invasion (HR 2.41, P = .002) to be independent risk factors for recurrence, whereas HCC diameter (HR 1.15, P = .041), HCC-MELD (HR 15.611, P = .006), and grading (HR 2.17, P = .03) proved to be predictive factors of poor overall survival.

CONCLUSION

Our study showed the validity of the HCC-MELD equation in the evaluation of patients undergoing LT for HCC. This score offers a reliable method to assess the risk of waiting list dropout and predict posttransplantation outcomes.

Cultural validation of the post-Liver transplant quality of life (pLTQ) questionnaire for the Brazilian population

BACKGROUND AND RATIONALE

The post-Liver Transplant Quality of Life (pLTQ) questionnaire, developed in the United States, is a disease-targeted instrument designed to evaluate health-related quality of life (HRQoL) in liver transplant recipients. Our study sought to validate a version of the pLTQ for use in the Brazilian population. Translation and cross-cultural adaptation were carried out in accordance with international standard practices for questionnaire validation. Validity was measured by means of convergent validity (correlations between pLTQ domains and WHOQOL-Bref domains). Reliability was assessed by measurement of internal consistency (Cronbach's alpha coefficient), reproducibility (intraclass correlation coefficient), sensitivity to change (effect size), and floor and ceiling effects.

RESULTS

The study sample comprised 160 liver transplant recipients, with a mean age of 56.9 ± 10.4 years, treated at a tertiary hospital in Southern Brazil. The sample was largely male (62.5%), and the predominant indication for liver transplant was hepatocellular carcinoma (49.4%). Only two questionnaire items were modified during the translation and cross-cultural validation stage. The mean total pLTQ score was 5.58 ± 0.9, with < 20% floor/ceiling effect. Correlations between pLTQ and WHOQOL-Bref domains were acceptable (r = 0.37-0.40). For similar dimensions, the correlations between WHOQOL-Bref and pLTQ were statistically significant (p ≤ 0.001). Cronbach's alpha for the total score was 0.91 (95% CI 0.89-0.93), with a range of 0.51 to 0.77 across domains. Reproducibility was 0.90, and sensitivity to change was 0.84.

CONCLUSION

In conclusion, the Brazilian Portuguese versión of the pLTQ exhibited good psychometric performance, suggesting that it can be a useful tool in the Brazilian cultural context.

Effects of Liver Function on Ionized Hypocalcaemia following Rapid Blood Transfusion

OBJECTIVE: Hypocalcaemia detrimentally affects the cardiovascular system and massive transfusion-related hypocalcaemia is particularly severe in end-stage liver disease patients undergoing liver transplantation (LT). This study, therefore, compared the severity and duration of ionized hypocalcaemia between patients with normal and impaired liver function. METHODS: Patients ( n = 26 per group) were transfused at a rate of 10 ml/kg within 10 min with packed red blood cells (PRBCs) during LT (group LP) or spinal surgery (group SP), or were infused with 0.9% normal saline during spinal surgery (group SN). Serum levels of ionized calcium were assessed before (T0), just after (T1), and at 20 (T2) and 60 min (T3) after transfusion. RESULTS: Transfusion with PRBCs caused more severe ionized hypocalcaemia than 0.9% normal saline at T1. In contrast to the faster (20 min) normalization in group SP, ionized hypocalcaemia in group LP persisted at T3. Serum ionized calcium levels at T3 showed correlations with vital signs, blood glucose, serum potassium, base deficit and lactate. CONCLUSION: Rapid blood transfusion caused more severe and prolonged ionized hypocalcaemia in patients with liver dysfunction than in those with normal liver function.
