    Objectives: To investigate the efficacy and safety of an immunosuppressive regimen of steroid avoidance in combination with induction therapy and tacrolimus in liver transplant recipients. Materials and Methods: Eighty-two adult liver transplant recipients were randomized into 2 groups: standard protocol group (n=41) in which steroids were withdrawn 3 months after the operation, and a 24-hour steroid avoidance group (n=41) in which steroids were eliminated within 24-hours. The incidence of acute rejections, infections (bacterial, fungal, and cytomegalovirus), and metabolic complications were analyzed between the groups. Results: The incidence of early posttransplant diabetes mellitus and the average dosage of insulin consumption among diabetic recipients were significantly higher in recipients in the standard protocol group than in the 24-hour avoidance group (P < .05). In addition, the incidence of hypertension and infection during the follow-up were also higher in patients of the standard protocol group (P < .05). The incidence of hypertension in the early posttransplant period, hyperlipemia, and acute rejection during the follow-up were comparable between the groups (P > .05). Conclusions: Twenty-four hour steroid avoidance combined with induction therapy and tacrolimus maintenance is a safe and efficient immuno­suppression strategy that can significantly reduce posttransplant infections and other complications owing to long-term use of steroids, without increasing the risk of acute rejection.

    Kaposi Sarcoma of the Ureter After Liver Transplant: Case Report and Literature Review
    (Başkent Üniversitesi, 2012-02) Chen, Yu; He, Xiao-shun; Qiu, Shao-peng; Zhao, Liang
    Kaposi sarcoma after an organ transplant is rare and infrequently involves internal organs. There are 2 reported cases in the English literature of Kaposi sarcoma originating from the transplant ureter after kidney transplant. We report a case of Kaposi sarcoma that occurred in the native ureter of the liver transplant recipient. Initially, the patient refused any further investigation and management and 2 years subsequent, had to undergo a left radical nephroureterectomy owing to the loss of renal function and distending pain. He recovered very well and no recurrence was detected at 47 months’ follow-up. To our knowledge, it is the first report in English. We review the literature on this topic and explore the therapeutic principles and histologic features of this sarcoma.
