Background:
Cyclosporine (CsA) and tacrolimus (Tac) in heart transplantation (HTx) have been compared but with certain drawbacks. We compared both drugs in a prospective analysis with medium-term follow-up.
Methods:
Hundred and six patients were randomized to receive CsA or Tac (53 per group). Target levels of CsA were 200-300 ng/mL in the first six months and 100-200 ng/mL thereafter. Tac levels were 10-15 and 5-10 ng/mL, respectively. We also used daclizumab as induction and mycophenolate mofetil (MMF) and steroids as maintenance therapy.
Results:
Baseline characteristics were similar. Survival (CsA 88.7% vs. Tac 81.1%; p = 0.493) was similar. There was a tendency for longer time to first rejection with CsA (93 ± 110 vs. 55 ± 81 d; p = 0.122). There were more rejection-free patients with Tac (39 vs. 28%; p = 0.233). CsA patients suffered more viral infections (0.41 ± 0.58 vs. 0.11 ± 0.31; p = 0.003). CsA patients developed hypertension often (64 vs. 43%; p = 0.032). Tac patients suffered more gastrointestinal complications (16 vs. 6%; p = 0.042). Renal function and the development of diabetes, dyslipidemia, or neurological complications was similar.
Conclusions:
Tac patients showed a tendency for longer time to first rejection, and there were more rejection-free patients with Tac and suffered fewer viral infections. Tac patients developed less hypertension and needed less drugs for its control. Renal function was similar in both groups.
