Research Sumary:

1)Chronic kidney disease among transplant recipients
The traditional focus of clinical research in kidney transplant recipients has been the reduction of acute rejection and prolongation of allograft survival.  In contrast, my research has focused on the importance of premature patient death among transplant recipients.  My research has highlighted a need for a paradigm shift in the management of these patients based on the concept that chronic kidney disease is not cured by transplantation and aggressive treatment of chronic kidney disease before, during and after transplantation is required to improve patient outcomes. My research has challenged the transplant community to abandon the treatment modality based categorization of patients as dialysis dependent, transplant and failed transplant in favor of a holistic approach that considers transplant recipients as patients with a chronic condition that requires an aggressive continuum of care.

2) Access to kidney transplantation
My research in this area has focused on defining the negative impact of waiting times on clinical outcomes after kidney transplantation.  We have demonstrated that patients continue to achieve a substantial benefit from transplantation with waiting times of up to three years.  We have also studied access to transplantation in specific patient groups.  We recently reported a low rate of transplantation among Canadians of Aboriginal ethnicity. Other studies in this area have addressed access to transplantation among the elderly, American Veterans, and access to preemptive transplantation among patients in the United States.

3) Quantification of allograft function
My research in this area has stressed the need to move beyond serum creatinine measurements alone as a marker of allograft function. Serum creatinine measurements alone are not an accurate measure of allograft function.  Using glomerular filtration prediction equations I have published on the level of allograft function achieved after transplantation and the subsequent rate of allograft decline.  Key contributions in this area include highlighting the fact that most transplant recipients only achieve a modest level of allograft function and that the subsequent decline in allograft function among long-term transplant recipients is slow.  These findings have disproved the long held assumption that kidney transplant recipients are at high risk for kidney function decline.  Further these studies have shown that therapeutic strategies to improve baseline allograft survival may be more beneficial that strategies to slow the progression of allograft decline.
