The albumin-bilirubin grade uncovers the prognostic relationship between hepatic reserve and immune dysfunction in HIV-associated hepatocellular carcinoma.

BACKGROUND: Hepatocellular carcinoma (HCC) is a leading cause of liver-related mortality in people living with HIV, where co-infection with hepatotropic viruses accelerates the course of chronic liver disease. AIM: To evaluate whether the albumin-bilirubin (ALBI) grade, a more accurate marker of liver dysfunction in HCC, might identify patients with progressive liver dysfunction in the context of HIV/hepatitis co-infection. METHODS: Using uni- and multi-variable analyses, we studied the albumin-bilirubin grade as a predictor of overall survival (OS) in a large, multi-center cohort of patients with HIV-associated HCC recruited from 44 centres in 9 countries within the Liver Cancer in HIV study group. Patients who underwent liver transplantation were excluded. RESULTS: A total of 387 patients, predominantly HCV co-infected (78%) with balanced representation of all Barcelona Clinic Liver Cancer (BCLC) stages (A = 33%, B = 18%, C = 37%, D = 12%) were recruited. At HCC diagnosis, 84% had been on anti-retrovirals for a median duration of 8.8 years. The albumin-bilirubin grade identified significant differences in median survival of 97 months for grade 1 (95% CI 13-180 months), 17 months for grade 2 (95% CI 11-22 months) and 6 months for grade 3 (95% CI 4-9 months, P < .001). A more advanced albumin-bilirubin grade correlated with lower CD4 counts (464/373/288 cells/mm3 for grades 1/2/3) and higher HIV viraemia (3.337/8.701/61.845 copies/mL for grades 1/2/3, P < .001). CONCLUSIONS: In this large, multi-center retrospective study, the albumin-bilirubin grade highlights the interplay between liver reserve and immune dysfunction as prognostic determinants in HIV-associated HCC

Transitioning Health Care Responsibility From Caregivers to Patient: A Pilot Study Aiming to Facilitate Medication Adherence During This Process

Transition in pediatric transplant recipients consists of both a physical shift in medical care location as well as a transition in health care responsibilities from caregivers to patients. The purpose of the present study was to test the feasibility of a pilot intervention aiming to facilitate the transition in health care responsibilities from caregivers to patients while patients are still receiving pediatric services. Twenty-two patients were enrolled in a two-session educational protocol aiming to facilitate transition of responsibility. Patients were recruited from an outpatient transplant clinic. Ten were referred because of suspected difficulty in transitioning of care, and 12 were consecutively recruited without any specific a priori concerns. Medication adherence, measured through the use of standard deviations of tacrolimus blood levels, and ALT levels were the medical outcome measures. Complete data are available for 20 patients. Mean ALT levels improved after the follow-up period. For referred patients, adherence and ALT levels improved. Standard deviation of tacrolimus decreased from 3.33 to 2.23, t = 2.52, p = 0.04. Mean ALT decreased from 120.33 to 63.99, t = 3.01, p = 0.01. Maximal ALT values decreased overall from 284.10 to 101.20, t = 2.61, p = 0.03. Our findings suggest that targeted education regarding transition in responsibility for adolescents’ own health care is feasible in the outpatient environment and may assist families who are facing this potentially challenging process. A randomized, controlled study with a substantial number of enrolled patients is needed to establish the efficacy of this or other approaches

Discordant role of CD4 T-cell response relative to neutralizing antibody and CD8 T-cell responses in acute hepatitis C.

BACKGROUND & AIMS: Acute hepatitis C virus (HCV) infection becomes chronic in the majority of patients. Although HCV-specific CD4 T-cell response is associated with HCV clearance, less is known about virus-specific CD8 T-cell or neutralizing antibody (nAb) responses and the role of CD4 help in their induction during acute infection. METHODS: HCV-specific CD4, CD8, and HCV pseudoparticle (HCVpp) nAb responses were monitored in acutely HCV-infected patients to define their relative contributions to viral clearance. RESULTS: Our results show that the outcome of acute hepatitis C is associated with a functional hierarchy in HCV-specific CD4 T-cell response and the scope of virus-specific, total T-cell interferon-gamma response. HCV-specific CD8 T-cell response was readily detectable in acutely HCV-infected patients regardless of virologic outcome or virus-specific CD4 T-cell response. In contrast, HCVpp-specific nAbs were readily detected in patients with chronic evolution and impaired virus-specific CD4 T-cell response but not in patients who cleared infection with robust virus-specific CD4 T-cell response. CONCLUSIONS: The outcome of acute hepatitis C is associated with efficient virus-specific CD4 T-cell response(s) without which HCV-specific CD8 T-cell and heterologous nAb responses may develop but fail to clear viremia. Furthermore, HCV-specific nAb responses may not be induced despite robust virus-specific CD4 T-cell response
