title: Incidence of hypertension after marrow transplantation among 112 patients randomized to either cyclosporine or methotrexate as graft-versus-host disease prophylaxis.
abstract: We investigated the frequency of hypertension (sustained diastolic blood pressure greater than or equal to 90 mmHg) in 112 patients given HLA-identical marrow grafts. Patients were conditioned with 2 X 60 mg/kg of cyclophosphamide and 6 X 2 Gy of total body irradiation and randomized to receive as graft-versus-host disease prophylaxis either the standard methotrexate regimen (n = 61) or cyclosporine (n = 51), starting on day -1 as 12.5 mg/kg/d orally or as 3 mg/kg/d i.v. and later converting to p.o. when oral intake was tolerated. Kaplan-Meier estimates indicate a 60% incidence of hypertension in the first 120 d in patients given cyclosporine (median time to onset: 4 d post transplant) compared to 20% in patients given methotrexate (P less than 0.0001). Multifactorial analysis using a Cox regression model showed that cyclosporine was was the most significant risk factor for developing hypertension (relative risk: 32.1, P less than 0.0001). In addition, glucocorticoids, used for treatment of GVHD, were associated with an increased risk for hypertension (relative risk 7.2, P less than 0.0001). Age, sex, underlying disease, cyclosporine trough levels, and renal function had no significant association with hypertension. Early therapy of hypertension in cyclosporine-treated patients appears to be indicated.
