Timing Is Everything: Managing Hepatitis C Virus in Liver Transplant Candidates

Longitudinal increase in albumin-bilirubin score is associated with non-malignancy-related mortality and quality of life in patients with liver cirrhosis

Due to the developments in the treatment for hepatitis, it is possible to prevent the progression of liver fibrosis and improve patients’ prognosis even if it has already led to liver cirrhosis (LC). Consequently, a two-step study was conducted. To begin with, a retrospective study was conducted to identify the potential predictors of non-malignancy-related mortality from LC. Then, we prospectively analyzed the validity of these parameters as well as their association with patients’ quality of life. In the retrospective study, 89 cases were included, and the multivariate Cox regression analysis indicated that age (P = 0.012), model for end-stage liver disease (MELD) score (P = 0.012), and annual rate of change of the albumin–bilirubin (ALBI) score (P < 0.001) were significantly associated with LC prognosis. In the prospective study, 70 patients were included, and the patients were divided into cirrhosis progression and non-progression groups. The univariate logistic regression analysis indicated the serum procollagen type III N-terminal peptide level (P = 0.040) and MELD score (P = 0.010) were significantly associated with the annual rate of change of the ALBI score. Furthermore, the mean Chronic Liver Disease Questionnaire score worsened from 5.3 to 4.9 in the cirrhosis progression group (P = 0.034). In conclusion, a longitudinal increase in the ALBI score is closely associated with non-malignancy-related mortality and quality of life.

Pharmacotherapeutic management of HIV in transplant patients

INTRODUCTION

In the last two decades, an increasing number of people living with HIV (PLWH) have undergone solid-organ and hematopoietic cell transplantation as a treatment of end-stage organ and hematological diseases, respectively. Although transplant outcomes are more than satisfactory, transplantation in PLWH is still challenging for clinicians because of concerns regarding potentially higher rates of infective complications, higher risks of allograft rejection, and drug-drug interactions between antiretroviral drugs and immunosuppressive agents.

AREAS COVERED

This review provides an overview of transplantation in PLWH, with focus on the management of combination antiretroviral therapy in this population.

EXPERT OPINION

Solid-organ and hematopoietic cell transplantations should be proposed without any reservation to all PLWH who may benefit from them. Particular attention should be paid to possible drug-drug interactions between antiretrovirals and immunosuppressive agents; moreover, when feasible, integrase strand transfer inhibitor-based antiretroviral regimens should be preferred to protease and non-nucleoside reverse transcriptase inhibitors. Considering the worse prognosis in HIV/hepatitis C virus (HCV) transplant recipients, treatment of HCV with new direct-acting antivirals (DAAs) represents a key issue in the management of this population. However, the timing of treatment (before or early after transplant) should be individualized by considering short-term prognosis, access to transplant, and comorbidities.

Baseline Factors Associated With Improvements in Decompensated Cirrhosis After Direct-Acting Antiviral Therapy for Hepatitis C Virus Infection

BACKGROUND & AIMS

Treatment with direct-acting antiviral (DAA) agents can reduce Model for End-Stage Liver Disease and Child-Pugh-Turcotte (CPT) scores in patients with decompensated cirrhosis caused by hepatitis C virus. However, many of these patients still die or require liver transplantation. We collected data on baseline features of patients and aimed to develop a scoring system to predict response to DAA therapy.

METHODS

We performed a retrospective analysis of data from 4 trials on the effects of sofosbuvir-based therapy in patients with hepatitis C virus-associated decompensated cirrhosis (502 of CPT class B and 120 of CPT class C). In these trials, patients were given 12 or 24 weeks of treatment with ledipasvir, sofosbuvir, and ribavirin or velpatasvir, sofosbuvir, and/or ribavirin, or 48 weeks of treatment with sofosbuvir and ribavirin. We collected demographic, clinical, treatment response, and laboratory data from patients and tested their associations with patient outcomes at 36 weeks. The primary outcome was factors associated with reduction of CPT score to class A.

RESULTS

The presence of ascites or encephalopathy, serum level of albumin <3.5 g/dL or alanine aminotransferase <60 U/L, and body mass index >25 kg/m² were associated with an increased risk of not achieving a reduction in CPT to class A, independent of sustained viral response to therapy. Serum level of albumin <2.8 g/dL and abnormal level of bilirubin were associated with an increased risk of liver transplantation or death. We developed a scoring system based on 5 baseline factors (body mass index, encephalopathy, ascites, and serum levels of alanine aminotransferase and albumin) associated significantly with patient outcomes, which we called the "BE3A score." For patients with scores of 4-5, the hazard ratio for reduction of CPT score to class A was 52.3 (95% confidence interval, 15.2-179.7).

CONCLUSIONS

We identified 5 baseline factors (body mass index, encephalopathy, ascites, and serum levels of alanine aminotransferase and albumin) associated with a reduction of CPT score to class A in patients with hepatitis C virus-associated decompensated cirrhosis receiving DAA therapy. We developed a predictive score using these factors, called the BE3A score, which can be used as a shared decision-making tool, quantifying the potential benefits of DAA therapy for patients with decompensated cirrhosis.
