[The highlights of dialysis in 2023].

There has been a wealth of new developments in dialysis this year with the publication of several trials relating to dialysis technique, physical activity and the use of new dialysis treatments. Quality of life should be assessed and managed in all dialysis patients. Lowering the temperature of the dialysis bath in the MyTemp trial does not appear to have an effect on mortality and cardiovascular events. High volume convective hemodiafiltration currently represents the reference technique in hemodialysis; the Convince study confirms its superiority in terms of all-cause mortality. The DIATT study shows the benefit of the presence of an adapted physical activity professional to promote physical activity in dialysis patients and shows that it is necessary for this support to be reimbursed. The RENAL-AF and AXADIA-AFNET 8 studies lack power to conclude on the use of new oral anticoagulants in hemodialysis. For angiotensin receptor neprilysin inhibitors, studies are too weak to allow their use. SGLT2 inhibitors could be used in peritoneal dialysis to increase diuresis or delay the appearance of peritoneal fibrosis but to date only studies on models animals exist. Factor XI inhibitors are a new therapeutic class that could be used and would reduce the risk of thrombosis and hemorrhage. Increasingly, the feelings of patients and caregivers are more and more taken into account. Patient/caregiver communication must be at the heart of care. We will also be looking at the conservative treatment, the management of pruritus in hemodialysis and finally the care of patients with calciphylaxis.
