[A unique case of recurrent malignant hypertension after removal of an adrenal tumor for primary aldosteronism].

We report here a unique case of recurrent malignant hypertension after the removal of an adrenal tumor for primary aldosteronism. The patient had a history of hypertension for 15 years. In 1995, he developed drug-resistant hypertension with hyperreninemia, hyperaldosteronemia and hypokalemia.

Plasma renin and aldosterone in adult-onset diabetics with persistent proteinuria.

Plasma renin activity (PRA) and plasma aldosterone (PA) were measured under conditions of bed rest and after administration of furosemide and/or angiotensin II to adult-onset diabetics and age-matched controls. Seventeen of the diabetics had no proteinuria (non-proteinuria group) while in the other ten subjects, there was a persistent proteinuria, but no hypertension and renal dysfunction (proteinuria group). In the non-proteinuria group, changes in PRA and PA levels during both bed rest time and after the stimulation with furosemide did not significantly differ from findings in the control group.
