The main finding of a reduction in intra-session hypotensive episodes is in line with earlier data regarding post-dilution haemofiltration [2]. Nevertheless, we do not entirely agree with the interpretation of the results.
From the observation that the episodes of symptomatic hypotension progressively decreased and pre-dialytic mean arterial pressure increased, the authors conclude that it is inaccurate to attribute the difference in haemodynamic response during haemodialysis and haemofiltration treatment to a
