Mortality in sufferers with kidney failure has been discovered to be 23% decrease amongst these handled with excessive dose hemodiafiltration in comparison with these handled with excessive flux hemodialysis, in keeping with new analysis from the CONVINCE consortium led by College Medical Heart Utrecht.
The research, printed at the moment within the New England Journal of Medication, is the primary worldwide, randomized trial to check the 2 therapies. The findings point out that wider use of high-dose hemodiafiltration would have clear advantages for sufferers.
Continual kidney illness is a number one international well being drawback that impacts an estimated 830 million individuals globally. When the kidneys can not do their job, dialysis is used to scrub the blood by eradicating waste merchandise, a perform usually carried out by the kidneys themselves. Round 4 million individuals are on dialysis worldwide.
Hemodialysis is the commonest type of dialysis used within the therapy for kidney failure. Although it has improved over time, it isn’t good at eradicating bigger molecules from the blood. Haemodiafiltration is a more moderen know-how that may take away bigger molecules, however it isn’t appropriate for all sufferers attributable to the truth that it requires a better blood circulate fee to be efficient. Earlier research have did not conclusively show that one technique is simpler than the opposite.
The CONVINCE trial has been led by researchers at UMC Utrecht along with collaborators at College Faculty London (UCL), Charité Universitätsmedizin Berlin, College of Bari, The George Institute for World Well being and Imperial Faculty London, together with dialysis suppliers Fresenius Medical Care, Diaverum and B. Braun Avitum. It’s the first multinational, randomized trial to check high-flux hemodialysis and high-dose haemodiafiltration, with the goal of clarifying which technique is superior.
At 61 facilities in eight European nations, a complete of 1,360 sufferers have been randomized, with 683 handled with high-dose haemodiafiltration and 677 handled with high-flux hemodialysis 3 times per week.
Throughout a median follow-up of 30 months, all-cause mortality was 21.9% amongst these handled with high-flux hemodialysis, in comparison with 17.3% for these handled with high-volume haemodiafiltration. This 4.6% distinction represents a 23% discount within the danger of loss of life.
Our outcomes present clear survival advantages for utilizing haemodiafiltration over hemodialysis to deal with kidney failure, akin to a 23% discount in all-cause mortality. My hope is that haemodiafiltration can develop into the brand new customary.”

Professor Matthias Rose (Charité College, Berlin), a senior writer of the research and skilled in patient-reported outcomes, stated: “Along with medical occasions, affected person notion and thus reported outcomes are crucial. We’re presently performing in-depth analyses of the intensive knowledge on patient-reported outcomes which have been collected within the CONVINCE research, with outcomes anticipated later this yr.”
Whereas hemodialysis is customary therapy in most nations, haemodiafiltration is much less extensively utilized in some locations and isn’t used in any respect in locations just like the US. Most trendy dialysis machines can carry out both technique, which might make a change to haemodiafiltration comparatively simple.
Professor Andrew Davenport (UCL Medication and the Royal Free Hospital), a senior writer of the research, stated: “Throughout my profession I’ve watched new therapies emerge for a lot of illnesses, from diabetes to most cancers, however we have not seen the identical advances within the therapy of power kidney illness. This research proves that focusing on totally different molecules by way of hemodiafiltration has clear advantages for sufferers. I’d say that that is the primary main step ahead in a few years and is sweet information for kidney illness sufferers and their households.”
