  • Hepatitis C virus (HCV) infection is the leading cause of liver disease in hemophilia patients. In those with human immunodeficiency virus (HIV)/HCV coinfection, the rate of liver disease progression is greater than in HCV monoinfected individuals. Despite antiretroviral therapy, which slows HCV liver disease progression, some require transplantation. Whether transplant outcomes are worse in hemophilic (H) rather than nonhemophilic (NH) candidates is unknown. In order to determine rates and predictors of pretransplant and posttransplant survival, we conducted a retrospective observational study using United Network for Organ Sharing national transplant registry data, comparing HCV+ H and NH candidates. We identified 2502 HCV+ liver transplant candidates from 8 US university-based transplant centers, between January 1, 2004 to December 31, 2010, including 144 HIV+ (6%) and 2358 HIV-; 36 H (1%) and 2466 NH; 1213 (48%) transplanted and 1289 not transplanted. Other than male predominance and younger age, each were P < 0.001. Baseline data were comparable between H and NH. In univariate analysis, 90-day pretransplant mortality was associated with higher baseline Model for End-Stage Liver Disease (MELD; hazard ratio [HR] = 1.15; P < 0.001), lower baseline platelet count (HR = 0.9 per 25,000/µL; P = 0.04), and having HIV/HCV+ hemophilia (P = 0.003). In multivariate analysis, pretransplant mortality was associated with higher MELD (P < 0.001) and was significantly greater in HIV+ than HIV- groups (P = 0.001). However, it did not differ between HIV+ H and NH (HR = 1.7; P = 0.36). Among HIV/HCV+, posttransplant mortality was similar between H and NH, despite lower CD4 in H (P = 0.04). In conclusion, this observational study confirms that hemophilia per se does not have a specific influence on transplant outcomes and that HIV infection increases the risk of mortality in both H and NH patients.

  • Liver retransplantation is performed in HIV-infected patients, although its outcome is not well known. In an international cohort study (eight countries), 37 (6%; 32 coinfected with hepatitis C virus [HCV] and five with hepatitis B virus [HBV]) of 600 HIV-infected patients who had undergone liver transplant were retransplanted. The main indications for retransplantation were vascular complications (35%), primary graft nonfunction (22%), rejection (19%), and HCV recurrence (13%). Overall, 19 patients (51%) died after retransplantation. Survival at 1, 3, and 5 years was 56%, 51%, and 51%, respectively. Among patients with HCV coinfection, HCV RNA replication status at retransplantation was the only significant prognostic factor. Patients with undetectable versus detectable HCV RNA had a survival probability of 80% versus 39% at 1 year and 80% versus 30% at 3 and 5 years (p = 0.025). Recurrence of hepatitis C was the main cause of death in the latter. Patients with HBV coinfection had survival of 80% at 1, 3, and 5 years after retransplantation. HIV infection was adequately controlled with antiretroviral therapy. In conclusion, liver retransplantation is an acceptable option for HIV-infected patients with HBV or HCV coinfection but undetectable HCV RNA. Retransplantation in patients with HCV replication should be reassessed prospectively in the era of new direct antiviral agents. Read More on PubMed
  • Hepatitis C virus infection is the major cause of end-stage liver disease and the major indication for transplantation (OLTX), including among HIV-HCV co-infected individuals. The age of HCV acquisition differs between haemophilic and non-haemophilic candidates, which may affect liver disease outcomes. The purpose of the study was to compare rates of pre- and post-OLTX mortality between co-infected haemophilic and non-haemophilic subjects without hepatocellular cancer participating in the Solid Organ Transplantation in HIV Study (HIV-TR). Clinical variables included age, gender, race, liver disease aetiology, BMI, antiretroviral therapy, MELD score, CD4 + cell count, HIV RNA PCR and HCV RNA PCR. Time to transplant, rejection and death were determined. Of 104 HIV-HCV positive subjects enrolled, 34 (32.7%) underwent liver transplantation, including 7 of 15 (46.7%) haemophilic and 27 of 89 (30.3%) non-haemophilic candidates. Although haemophilic subjects were younger, median 41 vs. 47 years, P = 0.01, they were more likely than non-haemophilic subjects to die pre-OLTX, 5 (33.3%) vs. 13 (14.6%), P = 0.03, and reached MELD = 25 marginally faster, 0.01 vs. 0.7 years, P = 0.06. The groups did not differ in baseline BMI, CD4, detectable HIV RNA, detectable HCV RNA, time to post-OLTX death (P = 0.64), graft loss (P = 0.80), or treated rejection (P = 0.77). The rate of rejection was 14% vs. 36% at 1-year and 36% vs. 43% at 3-year, haemophilic vs. non-haemophilic subjects, respectively, and post-OLTX survival, 71% vs. 66% at 1-year and 38% vs. 53% at 3-year. Despite similar transplant outcomes, pretransplant mortality is higher among co-infected haemophilic than non-haemophilic candidates. Read More on PubMed
  • Hepatitis C virus (HCV) is a controversial indication for liver transplantation (LT) in human immunodeficiency virus (HIV)-infected patients because of reportedly poor outcomes. This prospective, multicenter US cohort study compared patient and graft survival for 89 HCV/HIV-coinfected patients and 2 control groups: 235 HCV-monoinfected LT controls and all US transplant recipients who were 65 years old or older. The 3-year patient and graft survival rates were 60% [95% confidence interval (CI) = 47%-71%] and 53% (95% CI = 40%-64%) for the HCV/HIV patients and 79% (95% CI = 72%-84%) and 74% (95% CI = 66%-79%) for the HCV-infected recipients (P < 0.001 for both), and HIV infection was the only factor significantly associated with reduced patient and graft survival. Among the HCV/HIV patients, older donor age [hazard ratio (HR) = 1.3 per decade], combined kidney-liver transplantation (HR = 3.8), an anti-HCV-positive donor (HR = 2.5), and a body mass index < 21 kg/m(2) (HR = 3.2) were independent predictors of graft loss. For the patients without the last 3 factors, the patient and graft survival rates were similar to those for US LT recipients. The 3-year incidence of treated acute rejection was 1.6-fold higher for the HCV/HIV patients versus the HCV patients (39% versus 24%, log rank P = 0.02), but the cumulative rates of severe HCV disease at 3 years were not significantly different (29% versus 23%, P = 0.21). In conclusion, patient and graft survival rates are lower for HCV/HIV-coinfected LT patients versus HCV-monoinfected LT patients. Importantly, the rates of treated acute rejection (but not the rates of HCV disease severity) are significantly higher for HCV/HIV-coinfected recipients versus HCV-infected recipients. Our results indicate that HCV per se is not a contraindication to LT in HIV patients, but recipient and donor selection and the management of acute rejection strongly influence outcomes.

  • Hepatitis C virus (HCV) is the major cause of liver disease in haemophilia. Few data exist on the proportion with liver fibrosis in this group after long-term HCV and HIV co-infection. We conducted a cross-sectional multi-centre study to determine the impact of HIV on the prevalence and risk factors for fibrosis in haemophilic men with chronic hepatitis C. Biopsies were independently scored by Ishak, Metavir and Knodell systems. Variables were tested for associations with fibrosis using logistic regression and receiver operating curves (ROC). Of 220 biopsied HCV(+) men, 23.6% had Metavir ≥ F3 fibrosis, with higher mean Metavir fibrosis scores among HIV/HCV co-infected than HCV mono-infected, 1.6 vs. 1.3 (P = 0.044). Variables significantly associated with fibrosis included AST, ALT, APRI score (AST/ULN × 100/platelet × 10(9) /L), alpha-fetoprotein (all P < 0.0001), platelets (P = 0.0003) and ferritin (P = 0.0008). In multiple logistic regression of serum markers, alpha-fetoprotein, APRI and ALT were significantly associated with ≥ F3 fibrosis [AUROC = 0.77 (95% CI 0.69, 0.86)]. Alpha-fetoprotein, APRI and ferritin were significant in HIV(-) [AUROC = 0.82 (95% CI 0.72, 0.92)], and alpha-fetoprotein and platelets in HIV(+) [AUROC = 0.77 (95% CI 0.65, 0.88]. In a multivariable model of demographic and clinical variables, transformed (natural logarithm) of alpha-fetoprotein (P = 0.0003), age (P = 0.006) and HCV treatment (P = 0.027) were significantly associated with fibrosis. Nearly one-fourth of haemophilic men have Metavir ≥ 3 fibrosis. The odds for developing fibrosis are increased in those with elevated alpha-fetoprotein, increasing age and past HCV treatment.

  • Human immunodeficiency virus (HIV) infection accelerates liver disease progression in patients with hepatitis C virus (HCV) and could shorten survival of those awaiting liver transplants. The Model for End-Stage Liver Disease (MELD) score predicts mortality in HIV-negative transplant candidates, but its reliability has not been established in HIV-positive candidates.

  • The impact of highly active antiretroviral therapy (HAART) on progression to end-stage liver disease (ESLD) in human immunodeficiency virus (HIV)/hepatitis C virus (HCV) co-infection remains controversial. We studied 157 HCV+ haemophilic men (85 HIV+ and 72 HIV-), on whom dates of HIV and HCV seroconversion and clinical outcomes were known. Time to ESLD was determined by Kaplan-Meier product-limit methods and risk factors for ESLD progression were analysed by a Cox proportional hazards model. Among HIV+ men, ESLD was more common, 17 of 85 (20.0%) than in HIV-, eight of 72 (11.1%) and median ESLD-free survival significantly shorter, P = 0.009, hazard ratio 3.00 [95% confidence interval (CI): 1.27-7.08]. HAART treated HIV+ had longer ESLD-free survival than HIV+ untreated, 30.3 vs. 20.0 years, P = 0.043, hazard ratio, 3.14 (95% CI: 1.27-7.08), comparable with survival in HIV- men, P = 0.13, hazard ratio 2.20 (95% CI: 0.76-2.35). Progression was unrelated to HAART toxicity (n = 0) or HCV antiviral therapy (n = 7). HIV+ HAART Rx and HIV- did not differ in HCV duration, age at ESLD, age at death or present, overall or AIDS mortality, all P > 0.05. These data suggest that HAART improves ESLD-free survival, approaching that in HIV- men. Read More on PubMed
