ABSTRACT

This work is a 1-yr interim analysis of a prospective, randomized, multicenter trial evaluating the effect of corticosteroid-free immunosuppression on hepatitis C virus-positive (HCV(+)) liver transplant recipients following liver transplantation (LT). Patients received tacrolimus and corticosteroids (Arm 1; n = 80); tacrolimus, corticosteroids, and mycophenolate mofetil (MMF) (Arm 2; n = 79); or daclizumab induction, tacrolimus, and MMF (Arm 3; n = 153). At 1 yr, 64.1%, 63.4%, and 69.4% of patients achieved the composite primary endpoint of freedom from rejection, freedom from HCV recurrence, and freedom from treatment failure, respectively. Excellent patient and graft survival did not differ significantly among treatment arms. Freedom from HCV recurrence at 1 yr was 61.8 +/- 6.2%, 60.1 +/- 6.1%, and 67.0 +/- 4.3% in Arms 1, 2, and 3, respectively (P = not significant). Freedom from rejection was significantly higher in Arm 3 compared to Arm 1 (93.0 +/- 2.2% vs. 81.9 +/- 4.4%; P = 0.011). Multivariate analysis identified acute rejection (hazard ratio = 2.692; P = 0.001) and donor age (hazard ratio = 1.015; P = 0.001) as significant risk factors for HCV recurrence. HCV recurrence was not influenced by recipient demographics, HCV genotype, or immunosuppression. In conclusion, these results suggest that a corticosteroid-free regimen of tacrolimus and MMF following daclizumab induction is safe and effective in HCV(+) liver transplant recipients.

ABSTRACT

This study evaluated the pharmacokinetics and pharmacodynamics of a novel 3-dose regimen of daclizumab in de novo hepatitis C liver transplant recipients. In 30 of 156 recipients receiving daclizumab, mycophenolate mofetil, tacrolimus, and no steroids (Arm 3 of Hep C 3 Liver Study), daclizumab (2, 2, and 1 mg/kg, respectively) was given on days 1, 3, and 8 posttransplant, respectively, with trough, peak (C(max)), and CD25 saturation (CD(sat)) measured sequentially. Mean daclizumab C(max) was 50.3 microg/mL on day 1, and mean trough levels were 21.8, 25.7, and 9.9 microg/mL on days 3, 8, and 30, respectively. A significant decline in CD(sat) (mean, 15.7% to 4.7%) was observed on day 1 and was sustained throughout the study (2.8% on day 30). Daclizumab concentration > or = 5 microg/mL was the level where most of the effect on CD(sat) was noticed. Elevated baseline CD(sat) was observed in African Americans, patients weighing < or = 75 kg, and patients <60 years of age. After 365 days, 2 patients had experienced 3 rejections, 10 patients had recurrent hepatitis C, 4 patients died, and 2 grafts were lost. In conclusion, this novel 3-dose regimen is effective in rapidly achieving high therapeutic concentration of daclizumab and a significant decline in CD(sat) lasting over 30 days.

ABSTRACT

BACKGROUND: A two-part study was initiated to compare kidney transplant patient and transplant professional perceptions regarding immunosuppression-related physical changes and their impact on transplant recipients. METHODS: Parallel surveys were developed and administered to transplant patients and active transplant clinicians. RESULTS: Eighty percent of surveyed patients reported immunosuppression-induced hirsutism, gingival hyperplasia, acne, alopecia, or cushingoid facies. Hirsutism (94%) and gingival hyperplasia (51%) occurred more frequently in cyclosporine patients (p < 0.01); alopecia (30%) occurred more frequently in tacrolimus patients (p < 0.01). Patient reported incidence of physical changes significantly exceeded observations by professionals for every condition (p < 0.01), however 84.4% of affected patients reported feeling "happy to endure" changes "for the sake of having a transplant." Patients also reported emotional and social effects due to physical changes, an outcome underestimated by transplant professionals (p < 0.01). Patients and professionals communicated about physical changes; however, more than half of affected patients believed communication occurred "rarely/never" while over half of the professionals believed communication occurred "every visit/most of the time." Although most physicians believed changes could be addressed, doctors recommended treatment for less than half of the affected patients. When recommended therapy changes were pursued, treatments were effective in the majority of cases. CONCLUSIONS: Incidence of immunosuppression-related physical changes is high and somewhat dependent on drug regimen. Although patients seem willing to accept cosmetic changes for the sake of having a transplant, physical changes have a psychosocial impact that is underestimated by clinicians. Immunosuppression-related physical changes remain underaddressed; effective interventions offer opportunities for improved care.
