RESUMEN
BACKGROUND: According to the National Transplant Center (CENATRA), in 2013, a total of 2707 transplantations were performed in Mexico; of them, 10% (270 transplantations) were done in our Tertiary Care Hospital (Western National Medical Center). This means that one in 10 transplant recipients undergoes transplantation at our medical center. The aim of our study was to describe the characteristics of and to compare changes in the kidney transplantation program over time. MATERIALS AND METHODS: This was a cross-sectional study. Data were collected from the hospital transplant registry from January 1994 to December 2014. RESULTS: During the study period, 3643 kidney transplantations were conducted; most were living donor 3236 (89%), and only 407 patients (11%) received a graft from a deceased donor. Of living donors, 2786 (87%) were related, and 450 (13%) were genetically unrelated. The average recipient age was 28 years, and the average age of the donor was 34 years. It was observed that siblings donated more frequently (51%), followed by parents (34%). Among unrelated donors, spouses donated the most (66%). In 80% of cases, the cause of end-stage renal disease (ESRD) was unknown (80%). The most frequent renal replacement therapy was peritoneal dialysis (54%), followed by hemodialysis (18%); only 5% of patients received preemptive kidney transplant. The most frequent immunosuppression scheme was tacrolimus, mycophenolate mofetil, and prednisone in 70% of patients. CONCLUSION: The Western National Medical Center is the largest kidney transplantation program in Mexico. The main activity is living donor transplantation. Recipients are relatively young persons with unknown etiology of ESRD.

BACKGROUND: Early steroid withdrawal (ESW) can improve lipid and hemodynamic profiles without severe acute rejection (AR) events in renal transplant patients. Our objective was to evaluate the effects of ESW on the frequency and severity of AR. METHODS: A randomized, open-label, controlled clinical trial was performed on renal transplant recipients with a follow-up of 12 months. In the ESW group, patients were selected for corticosteroid treatment withdrawal on the fifth day post transplantation. In the Control group, patients continued with steroid treatment. All patients were over 18 years of age with panel reactive antibody (PRA) class I and II HLA <20%. RESULTS: In total, 71 patients, 37 in the ESW group (52.1%) and 34 in the Control group (47.9%), had comparable AR incidences at the end of the follow-up (16% vs 15%) (NS) (RR = 1.20, 95% CI = 0.32-3.33). Although renal graft survival was similar between the ESW and Control groups (87% vs 94%), renal function was superior in the ESW group (85 vs 75 mL/min). Additionally, hypertension was less frequent in the ESW group (3% vs 35%), requiring the use of fewer antihypertensives (8% vs 50%). CONCLUSIONS: ESW was also associated with better blood pressure control and similar AR risk. The ESW group exhibited stable renal function.
