Sympathetic activity, plasma renin activity (PRA) and kininogen levels in patients haemodialysed with acetate and bicarbonate.

Sympathetic, renin and kinin responses to an acetic and bicarbonate fluid in haemodialysed patients were investigated. Increases in dopamine-beta-hydroxylase (DBH) activity, PRA and kininogen levels were found during single dialysis but there was no difference in acetate and bicarbonate haemodialysis. The present results suggest that changes in sympathetic renin and kinin activity were similar in patients treated with either acetate or bicarbonate fluid.
