Acquired cystic kidney disease and arterial hypertension in hemodialysis patients

Abstract

ACKD is common in HD patients. Its prevalence and grade increase with the duration of dialysis treatment. ACKD is not associated with AH. There is a correlation between the diameter of the inferior vena cava, as a factor of circulating fluid volume, and AH in HD patients.

Blood Pressure and Hemodialysis

“…Numerous authors described a correlation between hypertension and hypervolemia in dialysis patients, since hypervolemia is the cause of hypertension in up to 90% of dialysis patients (De Leeuw, 1994, Katzarski et al, 1997, Kirchner, 1997, Luik et al, 1998, Özkahya et al, 1999, Remuzzi, 1999, Agarwal et al, 2011. Also our study with 86 included hemodialysis patients confirmed this as well (Ekart & Hojs, 2006). Estimation of excess of volume is dependent upon estimation of dry weight.…”

“…Hardly any studies dealing with this specific topic are to be found while the results of available studies do not clarify the likely involvement of ACKD in the development of hypertension in hemodialysis patients. The aim of our published study was to establish the prevalence and the grade of ACKD in patients on renal replacement therapy with hemodialysis, the frequency of hypertension in these patients as well as the possible connection between the presence of ACKD and hypertension in hemodialysis patients (Ekart & Hojs, 2006). In the study 86 hemodialysis patients (46 males and 40 females; mean age 51.3 years; mean duration of hemodialysis treatment 55.3 months) were included.…”

“…Hypertension was defined as systolic blood pressure of ≥ 150 mmHg, diastolic blood pressure of ≥ 90 mmHg and/or antihypertensive treatment. (Ekart & Hojs, 2006).…”

Simple renal cysts and arterial hypertension: does their evacuation decrease the blood pressure?

“…Other studies [1,6,7,[9][10][11] mostly determine the prevalence of renal cysts in hypertensive and nonhypertensive patients to identify the cysts responsible for an increased BP. The main shortcoming of those studies was in their design, that is, whether the groups of patients with or without hypertension differed in variables other than the presence or absence of cysts.…”

“…Several authors reported that simple renal cyst was related to high blood pressure (BP) in cross-sectional studies [6,7], and the reduction of BP after aspiration or removal of large cysts was also observed [8,9]. The other reports showed the disputable [3,10] or opposite results [11,12].…”
