[Hyperplastic changes and aldosterone content in the adrenal cortex in essential hypertension and primary aldosteronism].
Autopsy and operative material (adrenalectomy for hyperaldosteronism) was studied to elucidate morphology, incidence of nodules, aldosterone content in the adrenal of patients with essential hypertension (EH). It was established than nodular masses in the adrenals in the form of micro and macronodules are present in 80% of EH patients. Aldosterone content in the adrenals in both nodules and in the adjacent cortex is significantly higher than in the adrenals of patients without EH. This fact as well as increased cell nuclei size in the fascicular and glomerular zones indicate high secretory activity of the adrenals in EH. Clinicomorphological comparisons in patients after adrenalectomy because of hyperaldosteronism syndrome allow to conclude that grave forms of EH may be followed by aldosteronism syndromes with nodular hyperplasia of the adrenal cortex being the basis of the syndrome. Indications to adrenalectomy require clear criteria of differential diagnosis with primary aldosteronism.
