Background: We assessed the effect of hepatitis C seropositivity on the percentage of various T-cells in living donor renal transplant recipients (LDRTRs) and their association with intercurrent infections post renal transplantation (post-Tx).Methods: One hundred and thirty-three matching LDRTRs [A (seronegative) (68 patients) and B (seropositive) (65 patients) by ELISA] were studied prospectively 10 days, 6 months and 12 months post-Tx for intercurrent infections, acute rejection and T-cell% by flow cytometry.Results: CD4+, CD8+, CD4/CD8 were significantly higher 10 days post-Tx in Group B compared to Group A, p < 0.001. A significant increase in CD8% was seen 6-month post-Tx among Group B compared to Group A. No difference was detected between groups in (CD4+, CD8+, CD4/CD8, CD3–CD16/65+%), rate and severity of intercurrent infection, rate of acute rejection, 12 months post-Tx. A significantly higher rate of severe infections particularly urinary tract infections (UTI) was noted in Group B compared to Group A the first 3 months post-Tx particularly in those who received the combination of antithymocyte globulin (ATG) or basiliximab, tacrolimus, steroids, mycophenolate mofetil (MMF). CD4+% correlated negatively with intercurrent infections in Group B 6 months post-Tx.Conclusion: HCV+ patients are more prone to intercurrent infections the first 3 months post-Tx. Infection rate correlates positively with pre-transplant HCV seropositivity and immunosuppressive regimen.
