Peripheral circulation regulation in patients with the neuroendocrine metabolic form of hypothalamic syndrome

: Peripheral circulation and regulating hormonal (renin-angiotensin-aldosterone system) and electrolytic (plasma sodium and potassium) factors were studied in 102 patients with the hypothalamic syndrome neuroendocrine metabolic form administered pathogenetic therapy with antiserotonin and dopaminergic drugs as well as routine therapy. Blood plasma sodium vasopressin and aldosterone levels were found increased, arterial vessel reactivity in the forearm reduced, and venous circulation disordered in these patients. Routine therapy failed to normalize electrolytes and hormonal parameters and was conducive to a still more marked reduction of arterial vessel reactivity. Peritol therapy resulted in a reduction of vasopressin concentration and normalization of blood plasma sodium and aldosterone, as well as in improvement of the myogenic mechanisms of vascular tone regulation and normalization of venous circulation parameters. A course of parlodel therapy lead to normalization of blood plasma levels of vasopressin, aldosterone, and sodium but no changes in the regional vessels were observed.
