Item Steroid Avoidance Reduce the Cost of Morbidities After Live-donor Renal Allotransplants: A Prospective, Randomized, Controlled Study(Başkent Üniversitesi, 2011-04) Gheith, Osama A.; Ghoneim, Mohamed A.; Shokeir, Ahmed A.; Refaie, Ayman; Bakr, Mohamed A.; Nematalla, Ahmed H.Objectives: Steroids have had the main role in renal transplant for more than 4 decades. However, chronic use of steroids is associated with many comorbidities, owing to a lack of assessing cost-benefit of steroid avoidance in live-donor renal allotransplants. In this prospective, randomized, controlled study, we aimed to assess the cost-benefit of a steroid-free immunosuppression regimen among Egyptian live-donor renal transplants. Materials and Methods: One hundred patients were randomly allocated to receive tacrolimus, mycophenolate mofetil, and steroids for only 3 days (n=50 patients; study group) or tacrolimus, mycophenolate mofetil, and steroids on a maintenance basis (n=50 patients; control group). All patients received basiliximab (Simulect) induction, with median follow-up of 12 months. Results: Both groups showed comparable graft and patient survivals, rejection episodes, and graft functioning. Posttransplant comorbidities were significantly more prevalent in the steroid-maintenance group. Hypertension was detected in 4% of steroid-free group versus 24% in the steroid-maintenance group (P = .0009). Posttransplant diabetes mellitus, serious infections, and hyperlipidemia were significantly more prevalent in the steroid-maintenance group (P < .05). Associated hospitalization costs were 2.2-fold higher in the steroid-maintenance group than they were in the steroid-free group. One year after transplant, the cost of managing posttransplant comorbidities was significantly higher in steroid-maintenance group, despite comparable costs of immunosuppression. Conclusions: In low, immunologic risk recipients of live-donor renal transplants, using basiliximab induction and maintenance with tacrolimus, mycophenolate mofetil, steroid avoidance was associated with lower first annual total costs despite comparable immunosuppression costs, which was attributed to lower costs of associated morbidities.Item Proteinuria Among Primarily Sirolimus Treated Live-donor Renal Transplant Recipients' Long-term Experience(Başkent Üniversitesi, 2010-12) Hamdy, Ahmed F.; Ghoneim, Mohamed A.; Bakr, Mohamed A.Objectives: Recent evidence of a high incidence of proteinuria among de novo sirolimus-based regimens has been reported among renal transplant patients at short-term follow-up. We report on long-term evaluation of proteinuria among patients maintained on such regimen. Materials and Methods: Between May 2001 and January 2003, 132 patients received a renal allograft from a living donor and were randomized to 2 groups (steroids/sirolimus/tacrolimus, n=65) and (steroids/sirolimus/mycophenolate mofetil, n=67): Both received basiliximab induction. Retrospective review of those patients was performed, 5 years posttransplant with particular emphasis on the incidence of proteinuria. Results: The 5-year incidence of proteinuria was 29.2% and 38.8% among sirolimus/tacrolimus and sirolimus/mycophenolate mofetil group. Single DR-matched patients (P = .016) and the incidence of acute rejection (P = .039) were associated with significantly higher incidence of proteinuria. Moreover, the presence of mesangial matrix increased (P = .015), and glomerulosclerosis (P = .014), in 1-year protocol biopsies, was found to have a positive predictive value for current and future incidences of proteinuria. Proteinuria was found to be associated with significant inferior graft outcome. Recurrent original kidney disease, de novo glomerulopathy, and acute transplant glomerulopathy were responsible for early cases of nephrotic range proteinuria (first 2 years), while cases presented later were attributed to chronic allograft nephropathy. Conclusions: Proteinuria has become a recognized, serious event of primarily sirolimus-treated renal transplants patients, which is most probably of glomerular origin. It has been shown that proteinuria exerts a bad prognostic effect upon graft function and subsequent graft survival at 5-year follow-up.
