High Blood Pressure (HBP) is a common finding in patients with chronic kidney disease on dialyses. This research analyzed the relation between blood pressure (BP) and hydration status (HS) in chronic kidney patients under hemodialysis (HD) and peritoneal dialysis (PD) in a Brazilian Dialysis Center. Demographic data, BP, number of antihypertensive drugs (NAD) and HS by bioimpendance exam were collected from 89 patients (69 in HD; 20 in PD). There were findings of 55.1% of men, age between 57.6±16.4 years old, Caucasian ethnicity (80.9%), usage of 2.4±1.2 hypotension drugs in HD, 1.7±1.4 in PD. Systolic Blood Pressure (SBP)<140 mmHg in 27.5% patients before HD, in 40.6% after HD and in 55% under PD. Diastolic Blood Pressure <90 mmHg in 81.2%, 79.7% and 85% respectively. 43.8% with mean blood pressure (MBP)>100 mmHg (86.9±9.9 mmHg) and OH 0.5±2.5 liters. 56.2% with MBP>100 mmHg (114.7±11.9 mmHg; p=0.0001) and OH of 1.5±2.7 liters (p=0.06 between the groups). When pre-dialysis SBP and HS were combined, the patients were stratified in 4 groups: Group-1; 40.4% HBP can relate to hyperhydration; Group-2; 24.71%, HBP is independent of hyperhydration; Group-3; 19.1%, in which 9% are hypohydrated and low blood pressure; Group-4; 15.7%, in which 12.3% are normohydrated and normotensive and 3.4% are hyperhydrated, though normotensive or arterial hypotension. HS was normal in 22.5%. In this research, there was noted the difficulty of controlling BP in these patients despite the use of expressive NAD and no relation between HS and MBP.
