Atrial fibrillation as presenting sign of primary aldosteronism: results of the Prospective Appraisal on the Prevalence of Primary Aldosteronism in Hypertensive (PAPPHY) Study.

Background: Despite hyperaldosteronism being suggested as predisposing to arrhythmias, the relationship between atrial fibrillation and primary aldosteronism remains uncertain. Therefore, we tested the hypothesis that atrial fibrillation is a presentation of primary aldosteronism in hypertensive patients with unexplained atrial fibrillation.

Design And Methods: The Prospective Appraisal on the Prevalence of Primary Aldosteronism in Hypertensive (PAPPHY) Study recruited consecutive patients with atrial fibrillation and an unambiguous diagnosis of arterial hypertension at three referral centers for hypertension.

Comparison between two high-dose methylprednisolone schedules in the treatment of acute hepatic cellular rejection in liver transplant recipients: a controlled clinical trial.

Intravenous methylprednisolone is used in most liver transplant centers as first-line therapy of acute hepatic cellular rejection in patients who undergo liver transplant. However, no controlled study has been performed to date to define the optimal dose and duration of the steroid regimen. The schedules that actually are used in most transplant centers are drawn from those that were developed empirically for the treatment of acute renal graft rejection.
