Zusammenfassung: | Sympathetic response to differences in sodium intake in patients with chronic renal failure was investigated. All patients were on haemodialysis, first for 3 weeks with conventional dialysate containing 148 mEq/l of sodium, then for another 3 weeks with the conventional dialysate containing 131 mEq/l of sodium. Increase in noradrenaline (NA), adrenaline (A), dopamine (DA) concentrations and dopamine-beta-hydroxylase (DBH) activity were found during the high-sodium haemodialysis. However, DBH activity in patients was significantly lower than in healthy individuals. A significant correlation was found between the level of plasma NA and systolic blood pressure. The present results suggest that a higher intake of sodium causes dysfunction of the sympathetic system. |
