title: One-year observation of kidney allograft recipients converted from cyclosporine microemulsion to tacrolimus.
abstract: The results from previous trials suggested that tacrolimus-based treatment in kidney transplantation was associated with a significantly lower incidence of acute rejection, and that cyclosporine microemulsion (CsA-Me)-treated patients converted to tacrolimus had numerically better 6-year graft survival than those remaining on CsA-Me. Death with a functioning graft and chronic graft nephropathy are the leading causes of late allograft loss. While standard cardiovascular risk factors are relevant, renal function itself becomes an important risk factor for cardiovascular morbidity and mortality in kidney transplantation patients. Expected benefits of the conversion from CsA-Me to tacrolimus with respect to renal function and cardiovascular status were the rationale for this observational study. Twenty one patients underwent conversion due to nephrotoxicity of cyclosporine (n = 18) or side effects (n = 3). Two out of 21 patients did not complete the study. The patient survival after 1 year was 100% in this group of patients; graft survival 94.7%. No cases of de novo diabetes mellitus were identified. Mean serum creatinine fell from 2.13 +/- 0.4 to 1.84 +/- 0.3 mg/dL (P < .02) and calculated glomerular filtration rate increased from 49.6 +/- 14.4 to 56.2 +/- 15.5 mL/min (P < .01). Total cholesterol decreased from 229.4 +/- 50.1 to 195.9 +/- 28.5 mg/dL (P < .005) and, low-density lipoprotein cholesterol from 125.7 +/- 37.3 to 104.4 +/- 22.6 mg/dL (P < .02). No significant changes in mean systolic or diastolic pressure or blood glucose levels were observed. The results of this observational study showed that in a group of patients with raised creatinine levels at entry, conversion to tacrolimus resulted in improved graft function and a more favorable cardiovascular risk profile.
