Post-kidney transplant surgical complications under new immunosuppressive regimens.
New immunosuppressive regimens have decreased acute rejection rates after kidney transplant. However, the use of these new agents has modified the profile of surgical complications. We compared the incidence of surgical complications in relation with the use of three types of drugs: calcineurin inhibitors, antiproliferative agents, and mammalian target of rapamycin (mTOR) inhibitors. This retrospective study included 359 cadaveric recipients who received an allograft between 1997 and 2004. The mean age was 54 years. The prevalence of diabetes was 8.5% and that of obesity (body mass index > 30 kg/m(2)) was 15.4%. The mean follow-up time was 44 +/- 5.6 months. The regimen most frequently used was tacrolimus (TACRO), mycophenolate mofetil (MMF), and prednisone (PRED) (n = 172), followed by TACRO-PRED (n = 49), cyclosporine (CSA) and MMF and PRED (n = 41), and CSA-azathioprine (AZA) and PRED (n = 24). A surgical complication was considered to be any type of event during the first year, although minimal, directly related to surgery. The rate of surgical complications was 34.8% (122/350). Collections and bleeding were higher in CSA than in TACRO regimens, 12% versus 3.8% (P < .05) and 11.5% versus 3% (P = .002), respectively. The incidence of lymphoceles was higher in regimens with than without mTOR inhibitors: 16% versus 3.7% (P = .012). The incidence of surgical complications was not influenced by the use of MMF or diabetes. In conclusion, the use of mTOR inhibitor-based immunosuppressive regimens leads to a higher incidence of lymphoceles, while the use of MMF does not increase the incidence of surgical complications.
