Improvements in reducing acute rejection rates following kidney transplantation in the last decade have not been mirrored by improvements in long-term graft survival rates [1,2]. One of the major causes of late graft loss in renal transplant recipients is chronic allograft nephropathy (CAN) [3–5] (Figure 1). CAN is highly prevalent in renal transplant recipients, with moderate to severe CAN present in 24.7% of recipients at 1 year post-transplant and in 89.8% of recipients by 10 years post-transplant [6]. CAN is defined by the histopathological features of interstitial fibrosis and tubular atrophy, but can also be associated with subclinical rejection, transplant glomerulopathy [6–8] or transplant vasculopathy caused by smooth muscle cell proliferation [4,9]. Therefore, the term CAN is being employed quite widely to describe a clinical syndrome instead of defining the presence of interstitial fibrosis or tubular
Clinical guidance-—early detection before CAN becomes established
Clinical guidance—early intervention through identification of risk factors before CAN occurs
