title: Prolactin response to sulpiride in non insulin dependent diabetes mellitus.
abstract: Blood glucose, insulin and prolactin concentrations were determined before and after sulpiride injection (50 mg i.m.) in 20 non-insulin-dependent diabetic patients (10 with retinopathy and 10 without evidence of retinal damage) and 10 subjects with normal glucose tolerance. Prolactin response to sulpiride was significantly higher in diabetics than in controls (at 20 min., p less than 0.01; at 30 and 60 min., p less than 0.005; at 90 min., p less than 0.01; at 120 min., p less than 0.05). The sulpiride induced hyperprolactinemia did not influence blood glucose and plasma insulin levels in controls as well as in diabetic patients. Prolactin response to sulpiride was the same in diabetics with and in those without retinal changes. We conclude that acute hyperprolactinemia seems to have no influence on glucose homeostasis in normal and non insulin-dependent diabetic subjects.
