    Abstract:
    OBJECTIVE: Hepatitis C virus (HCV) infection remains an important risk factor for mortality and morbidity in transplant recipients. In this study, we retrospectively analyzed the impact of pretransplantation hepatitis C antibody status in HCV-infected renal allograft recipients on graft and patient survivals. PATIENTS AND METHODS: From February 1998 to August 2007, 933 renal transplantations were performed at our center. Of these, 104 patients were identified to be harboring HCV infection: 59 (group I) were anti-HCV positive prior to transplantation and 45 (group II) were HCV RNA/antibody positive in the posttransplantation period. The patients transplanted in different eras received different immunosuppressive regimens. Complete follow-up data were available for 72.3% (43/59) in group I and 80% (36/45) in group II. Both groups had a similar number of patients on cyclosporine (62.8% vs 61.1%), tacrolimus (37.2% vs 38.8%), and mycophenolate mofetil (MMF; 58.1% vs 61.1%). These patients were analyzed for differences in patient and graft survivals by log-rank test. RESULTS: The overall mean ages were 35.1 +/- 10.4 and 32.4 +/- 10.4 years, male to female ratios 37:6 and 31:5, mean donor ages 41.5 +/- 10.9 and 41.2 +/- 13.1 years, and mean follow-up durations 29.4 +/- 24 (range, 1-107.7) and 32.6 +/- 24.2 (range, 3.1-97.2) months in groups I and II, respectively. The patients in group I had received a significantly greater number of blood transfusions compared with patients in group II (6.2 +/- 5.7 vs 2.1 +/- 2.9) and a significantly greater number of dialysis treatments prior to transplantation (84.5 +/- 62.0 vs 33.8 +/- 43.2), respectively. Liver function tests--SGOT (22.6 +/- 16.1 vs 18.3 +/- 12.1 IU/L) and SGPT (24.2 +/- 28.9 vs 20.4 +/- 20.2 IU/L)-were similar in the 2 groups in the pretransplantation period, respectively. The patient and graft survivals at 5 years were similar: 88.6% vs 82.3% (P = .81) and 60.1% vs 62.5% (P = .75) in groups I and II, respectively. The serum creatinine values at last follow-up were 1.38 +/- 0.6 vs 1.7 +/- 2.4 mg% (P = not significant), SGOT 33.4 +/- 25.6 vs 38.3 +/- 47 IU/L, and SGPT 39.3 +/- 46.7 vs 59.2 +/- 89 IU/L in groups I and II, respectively. Liver decompensation occurred in 4 patients, 2 in each group at a mean duration of 36.5 months. CONCLUSION: Absence of HCV antibody does not confer any survival disadvantage in HCV-infected renal allograft recipients undergoing renal transplantation.
