Abstract
Hypertension is a common finding in end-stage renal disease patients with the prevalence between 20 to 85%. Al- though the etiology of arterial hypertension (AH) in this patient group is multifactorial, sodium and volume excess lead- ing to extracellular volume overload are one of the most important and potentially adjustable causes. Control of volume status can either normalize the blood pressure (BP) or make the AH easier to control in the great majority of dialysis pa- tients. Heavy reliance is placed on the dialysis procedure to gradually remove fluid over a period of days to weeks until a stable dry weight is achieved. Numerous attempts have been made to utilize alternative methods to more accurately as- sessment of dry weight, and the newest and most interesting method is multifrequency bioelectrical impedance spectros- copy (BIS). In this prospective study we used BIS in 65 haemodialysis (HD) patients in order to detect those with vol- ume-dependent hypertension and to further investigate the role of dry weight management in BP control. Dry weight was corrected at the beginning, and after 1, and 3 months. Final data were collected after six months. Our data showed that assessment of fluid overload using BIS provides better management of fluid status and BP control in the patients on maintenance HD, and that dry weight correction can lead to significantly better control of volume-dependent hyperten- sion in this patient group.
