In an effort to ameliorate the problem of orthostatic hypotension in pancreas transplant patients, current medical management consists of maximizing the patient's hydration, altering antihypertensives, increasing sodium intake, initiation of fludrocortisone, compression stockings, and behavioral modifications. Despite these medical interventions, a subset of patients remains symptomatic. Midodrine (ProAmatine), an alpha-adrenergic agonist, was approved for the treatment of symptomatic orthostatic hypotension in the US. This preliminary report attempts to assess the safety and efficacy of midodrine use in kidney/pancreas (KP) or pancreas alone (PA) transplant recipients. A retrospective review was performed of 7 KP and 1 PA recipient experiencing symptomatic postural hypotension after maximizing other medical treatments. Blood pressure, serum creatinine (SrCr), and objective responses to postural hypotension were assessed at routine intervals. Pre-midodrine monitoring revealed a mean orthostatic change in systolic blood pressure from sitting to standing of 43 mmHg (range 20-100 mmHg). Patients received a mean starting midodrine dose of 18 mg/d, which was titrated to a maximum dose of 30 mg/d. Systolic blood pressure monitoring revealed a mean orthostatic change of 27 mmHg (range 0-81 mmHg) after initiation of treatment with midodrine and a mean follow-up of 3.2 months. All study patients reported improvement in symptoms of orthostatic hypotension. SrCr was not affected based upon comparison of pre-treatment and current SrCr values of 1.4 and 1.3 mg/dL, respectively. The most common side effect experienced was supine hypertension. These preliminary results suggest that midodrine is safe and effective in transplant recipients; however, the dosage should be titrated to symptomatic relief or a maximum dose of 30 mg. Careful monitoring for supine hypertension is necessary.
