RESUMO

INTRODUCTION AND AIM: Sofosbuvir (SOF)-based regimen has been shown to have high efficacy even in patients with decompensated cirrhosis. Treated patients may experience various degrees of hepatic recovery ranging from stabilization of liver function, to removal from liver transplant wait lists. The frequency of these occurrences in larger transplant eligible patient populations is unknown. The aim of this study was to assess the efficacy of SOF-based therapy in HCV infected transplant eligible patients and to evaluate short term changes in liver function and the effect on their liver transplant status. MATERIAL AND METHODS: A retrospective multicenter Canadian study of liver transplant candidates with advanced HCV cirrhosis treated with SOF-based therapy. Outcomes included sustained virologic response (SVR), and liver transplant status. RESULTS: 105 liver transplant candidates with advanced liver disease due to HCV were evaluated. The overall SVR was 83.8%. Hepatocellular carcinoma was diagnosed in 39 (37.1%) prior to transplant evaluation. In short term follow-up, 14 (13.3%) remained active on the list at the time of SVR12, 22 (20.9%) patients underwent liver transplantation, 7 (6.6%) patients were deactivated due to clinical improvement, 3 patients were delisted, and 10 deaths were reported. CONCLUSIONS: SOF-based therapy for patients progressing to liver transplantation leads to high SVR rates, short term stability in liver function, and deactivation from the transplant list .

RESUMO

ABSTRACT Introduction. To identify the impact of portal vein thrombosis (PVT) and associated medical and surgical factors on outcomes post liver transplant (LT). Material and methods. Two analyses were performed. Analysis One: cohort study of 505 consecutive patients who underwent LT (Alberta) between 01/2002-12/2012. PVT was identified in 61 (14%) patients. Analysis Two: cohort study of 144 consecutive PVT patients from two sites (Alberta and London) during the same period. Cox multivariable survival analysis was used to identify independent associations with post-LT mortality. Results. In Analysis One (Alberta), PVT was not associated with post-LT mortality (log rank p = 0.99). On adjusted analysis, complete/occlusive PVT was associated with increased mortality (Hazard Ratio (HR) 8.4, p < 0.001). In Analysis Two (Alberta and London), complete/occlusive PVT was associated with increased mortality only on unadjusted analysis (HR 3.7, p = 0.02). On adjusted analysis, Hepatitis C (HR 2.1, p = 0.03) and post-LT portal vein re-occlusion (HR 3.2, p = 0.01) were independently associated with increased mortality. Conclusion: Well-selected LT patients who had PVT prior to LT had similar post-LT outcomes to non-PVT LT recipients. Subgroups of PVT patients who did worse post-LT (complete/occlusive thrombosis pre-LT, Hepatitis C or post-LT portal vein re-occlusion) warrant closer evaluation in listing and management post-LT.

RESUMO

The transition from regular use of cyclosporine to the newer calcineurin-inhibitors, such as tacrolimus, has been suggested as a contributing factor to the "era effect" of worsening outcomes of post-transplant HCV recurrence. This retrospective medical chart review of 458 patients was undertaken to evaluate the role of immunosuppressant choice (cyclosporine vs. tacrolimus) in determining virologic response and clinical outcomes of post-liver transplant HCV infection recurrence. Our results showed that patients undergoing interferon-based treatment taking cyclosporine have significantly better odds (OR: 2.59, P = 0.043) of presenting a sustained viral response (66.7%) compared to tacrolimus (52.8%). This did not result in a significant effect on post-liver transplantation clinical events including HCV-related deaths, graft loss, fibrosing cholestatic hepatitis, hepatocellular carcinoma or graft rejection. Other variables, which showed a significant relationship with the achievement of sustained viral response included donor age (OR 0.96, P = 0.001) and HCV genotype 1 infection (OR 0.05, P < 0.001). The observed significant increase in the odds of acute/hyperacute (OR 6.49, P = 0.001) and chronic rejection (OR 10.45, P < 0.001) in the cyclosporine to tacrolimus switch group, accompanied by an increase in the odds of HCV-related death (OR 2.30, P < 0.047) compared to tacrolimus merits further study. A significant increase (P < 0.044) in new-onset diabetes mellitus with tacrolimus (28.3%) compared to cyclosporine (18.7%) was also observed. Pre-transplant diabetes mellitus was associated with a significantly increased likelihood of graft fibrosis (HR 1.95, P = 0.003).

RESUMO

INTRODUCTION: Liver transplantation is a highly effective treatment for end-stage liver disease. However, there is debate over the practice of liver transplantation in older recipients (age ≥ 60 years) given the relative shortage of donor grafts, worse post-transplantation survival, and concern that that older patients may utilize excess resources postoperatively, thus threatening the economic feasibility of the procedure. AIM: To determine if patients ≥ 60 years of age utilize more health resources following liver transplantation compared with younger patients. MATERIAL AND METHODS: Consecutive adult patients who underwent primary liver transplantation (n = 208) at a single center were studied over a 2.5-year period. Data were collected on clinico-demographic characteristics and resource utilization. Descriptive statistics, including means, standard deviations, or frequencies were obtained for baseline variables. Patients were stratified into 2 groups: age ≥ 60 years (n = 51) and < 60 years (n = 157). The Chi-Square Test, Mantel-Haenszel Test, 2-sample test and odds ratios were calculated to ascertain associations between age and resource utilization parameters. Regression analyses were adjusted for model for end-stage liver disease score, location before surgery, diabetes mellitus, donor age, cold ischemia time, albumin, and diagnosis of hepatitis C. RESULTS: Recipients ≥ 60 years of age have similar lengths of hospitalization, re-operative rates, need for consultative services and readmission rates following liver transplantation, but have longer lengths of stay in the intensive care (hazard ratio 1.97, p = 0.03). CONCLUSION: Overall, liver transplant recipients ≥ 60 years of age utilize comparable resources following LT vs. younger recipients. Our findings have implications on cost-containment policies for liver transplantation.

RESUMO

BACKGROUND: Current practice guidelines recommend liver biopsy prior to treatment of hepatitis C genotype-1 but not for genotype-2/3; this is based on expert opinion, not on published evidence. METHODS: In retrospective analysis of a large trial database prior to the publication of recent guidelines, we compared outcomes in 985 treatment-naïve patients with hepatitis C who did or did not undergo liver biopsy before starting peginterferon alfa-2a plus ribavirin. RESULTS: Physicians elected to treat 141/654 (21.6%) genotype-1 patients and 126/331 (38.1%) genotype-2/3 patients without liver biopsy. There were no differences in baseline characteristics among those with or without pre-treatment liver biopsy, except for female preponderance in genotype-1 patients with liver biopsy. The sustained viral response (SVR) rate was no different amongst genotype-2/3 patients who had a biopsy before treatment with 66.3% SVR vs. 69.8% of those treated without biopsy (p = 0.546), but significantly higher among genotype-1 patients with pre-treatment liver biopsy at 54.6 vs. 44.0% for those treated without a liver biopsy (p = 0.029). In genotype-1 patients with liver biopsy, more patients with cirrhosis had dose adjustments (p = 0.0057) rather than drug discontinuation. There was tendency for earlier discontinuation among patients without pre-treatment liver biopsy. CONCLUSIONS: Pre-treatment liver biopsy was associated with better SVR amongst genotype-1 patients. This improvement may reflect ongoing commitment to completing the treatment course by both patient and physician. In genotype-2/3 patients, pre-treatment liver biopsy may not be essential to maximize SVR rates. This study validates the recommendations of the most recent treatment guidelines for hepatitis C.

RESUMO

Polycystic liver disease (PLD) is a celiopathy characterized by progressive growth of multiple hepatic cysts. In a minority of patients, severe symptomatic hepatomegaly necessitates liver transplantation (LT). The purpose of this study is to describe the postoperative and long-term outcomes of all patients transplanted for PLD at our center. All patients who underwent LT for PLD were identified through our database. Using patient charts, data were extracted on patient demographics and medical history, postoperative surgical and medical complications, length of hospitalization, prevalence of chronic kidney failure, and patient and graft survival. Subjects were contacted in April 2010 to verify their survival and confirm their need, if any, for hemodialysis and/or kidney transplantation. Descriptive statistics for patient and graft survival were performed. From 1993 to 2010, 14 subjects underwent LT and 1 subject underwent combined kidney and LT; all subjects were female and the mean age was 49.0 years. 10 (66.7%) subjects had polycystic kidney disease. Patients experienced a high rate of vascular complications, including hepatic artery thrombosis (HAT) or stenosis in 3 (20%) and 2 (13.3%) subjects, respectively. One subject had early graft loss due to HAT and underwent re-transplantation. The mean length of hospitalization was 18.8 days. After a mean of 66.8 months of follow-up (3-200), 13 (86.7%) subjects are alive with satisfactory graft function, and no patients had renal failure. In conclusion, patients who underwent LT for PLD had a high rate of postoperative vascular complications. However, long-term patient and graft survival, and kidney function, is excellent.
