title: Gingival overgrowth in kidney transplant recipients treated with cyclosporine and its relationship with chronic graft nephropathy.
abstract: Our previous study of a group of renal transplant recipients treated with CsA showed a significantly faster development of chronic graft failure among patients with gingival hyperplasia (GH) compared to unaffected patients. The aim of the present research was to establish the impact of CsA dose and blood levels on the incidence of chronic graft nephropathy and gingival overgrowth as well as to assess risk factors for chronic graft nephropathy. The study included 64 renal graft recipients (32 patients with GH and 32 without GH) transplanted between 1989 and 1994. There were no significant differences between the pretransplant demographic and clinical data of the patients with and without GH. Patients with GH received a significantly higher total yearly dosages of CsA compared those without GH (P <.03). Serum creatinine in the first year posttransplant in patients with GH was 1.9 mg/dL versus 1.6 mg/dL in those without GH. During 9 to 14 years follow-up, end-stage renal failure due to chronic nephropathy occurred in 18 patients (56%) with GH and eight patients (25%) without GH. Ten-year renal graft survival was 35% in GH patients and 69% in patients without GH. Ten-year patient survival was 69% in the GH group and 91% in the group without GH. CsA dosage was a risk factor for GH and for graft loss, which implies a role of CsA toxic effects on the pathological mechanisms of GH and of chronic allograft nephropathy.
