The Impact

AbstractBackgroundIncreased short-term blood pressure (BP) variability (BPV) in hemodialysis is associated with increased cardiovascular and all-cause mortality. Studies on the impact of BP-lowering interventions on BPV are scarce. This study examined the effect of dry-weight reduction with a lung ultrasound-guided strategy on short-term BPV in hemodialysis patients with hypertension.MethodsThis is a prespecified analysis of a randomized clinical trial in 71 hemodialysis patients with hypertension, assigned in a 1:1 ratio in the active group, following a strategy for dry-weight reduction guided by pre-hemodialysis lung ultrasound and the control group following standard-of-care treatment. All patients underwent 48-hour ambulatory BP monitoring at baseline and after 8 weeks. BPV was calculated with validated formulas for the 48-hour interval and the 2 daytime and nighttime periods.ResultsDry-weight changes were –0.71 ± 1.39 in active vs. +0.51 ± 0.98 kg in the control group (P < 0.001), generating a between-group difference of 5.9/3.5 mm Hg (P < 0.05) in 48-hour BP at study end. All brachial BPV indices [SD, weighted SD, coefficient of variation, and average real variability (ARV)] did not change significantly from baseline to study end in the active [systolic blood pressure (SBP)-ARV: 12.58 ± 3.37 vs. 11.91 ± 3.13, P = 0.117; diastolic blood pressure (DBP)-ARV: 9.14 ± 1.47 vs. 8.80 ± 1.96, P = 0.190] or control (SBP-ARV: 11.33 ± 2.76 vs. 11.07 ± 2.51, P = 0.544; DBP-ARV: 8.38 ± 1.50 vs. 8.15 ± 1.49, P = 0.295) group (between-group comparison P = 0.211/0.117). Aortic BPV indices followed a similar pattern. Likewise, no significant changes in BPV indices for the daytime and nighttime periods were noted in both groups during follow-up.ConclusionsThis study is the first to evaluate the effects of a nonpharmacological intervention on short-term BPV in hemodialysis, showing no effect of dry-weight reduction on BPV, despite BP decrease.

Abstract Introduction and purpose Arterial stiffness and aortic blood pressure (BP) augmentation are significantly increased in hemodialysis patients. Recent studies suggest that the prognostic significance of ambulatory recordings of arterial stiffness is high in hemodialysis. This study examines for the first time the effect of dry weight reduction with a standardized lung-ultrasound-guided strategy on ambulatory aortic BP and arterial stiffness parameters in hypertensive hemodialysis patients. Methods A total 71 hemodialysis patients with hypertension (mean home BP ≥135/85 mmHg), that were clinically euvolemic, were included in this single-blind randomized clinical trial. Patients were randomized in a 1:1 ratio in the active group (n=35), following a strategy for dry-weight reduction guided by the total number of US-B lines (US-B lines score) prior to a mid-week dialysis session and the control group (n=), following standard-of-care treatment. All patients underwent 48-hour ABPM with the Mobil-O-Graph monitor (IEM, Stolberg, Germany) and PWV measurement in office with SphygmoCor (ArtCor, Sydney, Australia) at baseline and after 8-weeks. Results Overall, the US-B lines change during follow-up were −5.3±12.5 in active versus +2.2±7.6 in control group (p<0.001), which corresponded to dry-weight changes of −0.71±1.39 versus +0.51±0.98 kg (p<0.001). The change in 48-hour cSBP was significantly greater in the active group (−6.30±8.90 vs −0.50±12.46, p=0.027); the relevant cDBP fall was marginally greater (−3.85±6.61 vs −0.63±8.36, p=0.077) in the active group. 48-hour cPP (41.51±9.63 vs 39.06±9.61 mmHg, p=0.004) and 48-hour PWV (9.30±2.00 vs 9.08±2.04 m/sec, p=0.032) were significantly reduced from baseline to study-end in the active group but remained unchanged in controls. In contrast, 48-hour AIx and AIx(75) did not change between baseline and study-end in both groups; changes in AIx(75) were similar in the two groups (−0.97±3.51 vs −0.36±4.25, p=0.517). PWV measured in office was decreased from baseline to study-end in the active (10.07±2.66 vs 9.79±2.81, p=0.038) but not in the control group. Conclusions A lung-ultrasound-guided strategy for dry-weight reduction reduces ambulatory aortic BP and ambulatory or office PWV, but not ambulatory AIx(75). These results suggest that dry-weight reduction can primarily reduce aortic BP levels and large arteries stiffness but not wave reflections from the periphery.

Abstract Background and Aims Hypertension is highly prevalent and independently associated with adverse outcomes in patients undergoing hemodialysis. The main mechanism leading to BP elevation in these individuals is their inability to maintain water homeostasis. This study examines the long-term effects of dry-weight reduction with a standardized lung-ultrasound-guided strategy on ambulatory BP in hypertensive hemodialysis patients. Method This is the report of the 12-month trial phase of a randomized controlled trial in 71 clinically euvolemic, hemodialysis patients with hypertension. Patients were randomized (1:1 ratio) in the active group (23 male and 12 female), following dry-weight reduction guided by the total number of US-B lines prior to a mid-week dialysis session and the control group (24 male and 12 female), following standard-of-care treatment. A 48-hour ABPM was performed in all study participants at baseline and after 12 months. Results During follow-up more patients in the active compared to control group had dry weight reduction (71.4% vs 22.2%; p&lt;0.001). US-B lines -4.83±13.73 vs 5.53±16.01; p=0.005) and dry-weight (-1.68±2.38 vs 0.54±2.32; p&lt;0.001) decreased in the active and slightly increased in the control group. At 12 months, 48-hour SBP (136.19±14.78 vs 130.31±13.57; p=0.034) and DBP (80.72±9.83 vs 76.82±8.97; p=0.008) were lower compared to baseline in the active but similar in the control group. Changes in 48-hour SBP (-7.78±13.29 vs -0.10±14.75; p=0.021) were significantly greater in the active compared to the control group. Comparisons for intradialytic, 44-hour, Day-1, Day-2 and day- and night-time BP were to the same direction. The proportion of patients experiencing at least one episode of intradialytic hypotension was numerically lower in the active group (71.4% vs 88.9%, p=0.065). Conclusion A lung-ultrasound-guided strategy for dry-weight reduction can effectively and safely decrease ambulatory BP levels during a 12-month follow-up period This method is a simple treatment approach to improve hypertension management in hemodialysis patients.
