Randomized Controlled Trial Comparative Study Clinical TrialAssessment of myocardial hypertrophy by echocardiography in adult patients receiving tacrolimus or cyclosporine therapy for prevention of acute GVHD.
The incidence of myocardial hypertrophy was determined in a comparative study of tacrolimus-based immunosuppression with cyclosporine-based immunosuppression for prevention of acute graft-versus-host disease (GVHD) after unrelated donor bone marrow transplantation. Patients were evaluated for clinical and echocardiographic abnormalities at baseline (prior to pretreatment conditioning and the first dose of study drug) and at 5-8 weeks after transplant when stable levels of oral tacrolimus or cyclosporine had been achieved. Left ventricular geometry and performance were assessed by echocardiography which included 2-D measurements and one Doppler measurement. ⋯ The incidence of myocardial hypertrophy (change of LVMI from <111 g/m(2) baseline to >111 g/m(2) post transplant) was 20% in the tacrolimus group and 56% in the cyclosporine group (P = 0.109). Changes in the LVMI from baseline to post baseline were greater with cyclosporine than with tacrolimus therapy, and there was no evidence that tacrolimus causes myocardial hypertrophy or significant clinical changes in adult bone marrow transplant patients. The increase in LVMI after transplant in the cyclosporine group was greater than in the tacrolimus group but was not associated with any significant clinical events.
