Key result
Four hours of haemodialysis and haemofiltration linked to a ~55% reduction in plasma ANP.
Why the study?
Does haemodialysis or haemofiltration reduce plasma atrial natriuretic peptide levels to normal in patients with end-stage renal disease?
Population
20 patients with end-stage renal disease (n=15 for haemodialysis, n=5 for haemofiltration)
Comparison
4 h haemodialysis or 4 h haemofiltration vs Pre-treatment baseline and between-group…
Design
Cohort
Follow-up
4 hours of treatment and 60 minutes post-treatment

Persistent ANP elevation after HD/HF in ESRD warrants caution on volume-centric assumptions; leaves open contributions from cardiac dysfunction and lost renal clearance.

Does haemodialysis or haemofiltration reduce plasma atrial natriuretic peptide levels to normal in patients with end-stage renal disease?
Absolute Event Rate: 67% vs 79%
High levels of biologically active ANP in end-stage renal disease are not fully normalized by haemodialysis or haemofiltration, suggesting contributions from hypervolaemia, occult cardiac dysfunction, and loss of renal clearance.
Raine et al. (1989) conducted an observational in End-stage renal disease (n=20). Haemodialysis vs. Haemofiltration was evaluated on Plasma concentrations of atrial natriuretic peptide (ANP). Four hours of haemodialysis and haemofiltration markedly reduced plasma atrial natriuretic peptide (mean 156 to 67 pmol/l and 170 to 79 pmol/l, respectively), though levels remained above normal.
