Abstract The association between acute cellular rejection (ACR) and the development of chronic rejection has been the subject of much debate. Studies have suggested that the two phenomena may be linked, or, conversely that there may be no association at all. In order to clarify this relationship the outcome of 284 renal allografts were examined. The transplants were all performed at a single institution between April 1989 and December 1991, allowing a minimum follow up of 5 years. ACR was classified into three clinical response groups: (1) fully responsive to therapy (type 1 ACR), (2) partially responsive (type 2) and (3) ACR requiring treatment with ATG or OKT3 (type 3). Acute and chronic rejection were determined by histological (Banff) criteria. Chronic transplant nephropathy (CTN) occurred significantly more frequently in those with late ACR after day 60 than in those who had early rejection (53.5 % versus 17.3 %, respectively, P 〈 0.00001). Acute rejection that was fully responsive to therapy (type 1) had no association with CTN, but partially responsive rejection and rejection requiring second-line treatment were both significantly associated with CTN (P 〈 0.0001 and P 〈 0.001, respectively). This study suggests that it is the clinical behaviour and response to treatment of ACR that is paramount in determining the onset of chronic rejection, and not the mere presence or absence of the clinical phenomenon.
