Influence of V2 vasopressin receptor agonist, 1-dezamino-8-D-arginine-vasopressin, DAVP, on a sensitivity disorders in stroke patients

Abstract

Somatosensory disorders often developed after a stroke. It is known that they affect the outcome of the disease negatively. We analyzed the effects of vasopressin in correction of sensitivity disorders in stroke patients. Treatment received 15 patients with strokes from 41 to 67 years old in most cases with remote consequences of stroke. 13 patients had survived ischemic stroke, 2 patients - hemorrhagic stroke. V2 vasopressin receptor agonist, 1-dezamino-8-D-arginine-vasopressin, DDAVP, were injected intranasal for 2 weeks. DDAVP was effective in 73 % of cases. The therapeutic effect of neuropeptide manifested in decreasing symptoms of pain disorders, temperature and tactile sensitivity. The total intensity of surface and deep sensitivity disorders decreased. Aggregate severity of all types of disorders of sensitivity was significantly decreased after treatment. Thus, DDAVP may be used as monotherapy in patients with strokes and with central sensitivity disorders.
