In particular, the working group recommends abandoning terms that used to correspond in French to “chronic renal failure”, “acute renal failure”, “end-stage renal failure”, “uremia”, “cadaveric donor” and “microalbuminuria”, in favor of French equivalents of “chronic renal disease”, “acute kidney injury”, “renal failure”, “uremic syndrome”, “deceased donor” and “albuminuria”. Arguments against the former and in favor of the latter are presented. Other equivalents of English terms from the KDIGO nomenclature are presented in a Table, and an Appendix presents equivalents proposed in German and Spanish by other authors.

A working group of the Transplantation Commission of the French-speaking Society of Nephrology, Dialysis and Transplantation (SFNDT) conducted a survey on the management of immunosuppressants (IS) after KTF among nephrologists at transplant centres and general nephrologists in France, Switzerland and Belgium between March and June 2023.\u0000We analysed 232 replies from 58 nephrologists at transplant centres and 174 general nephrologists, aged 43.6 (+10.6) years. In the first three months following KTF, nephrologists reported discontinuing antimetabolite, calcineurin inhibitor (CNI) and corticosteroid treatment in 83%, 39.9% and 25.8% of cases respectively. Conversely, some nephrologists reported that they were continuing to use CNI (14%) and corticosteroids (19.1%) on a long-term basis. The patient’s comorbidities associated with the discontinuation of IS treatment are cancer and opportunistic infections as KT’s complications and presence of diabetes mellitus at KTF, whereas humoral rejection encourages the IS to be maintained. Transplantectomy is proposed by nephrologists most often for graft intolerance syndrome (86.5%), more rarely to discontinue IS (17.6%) or in the absence of plans of new transplantation (9.3%). In multivariate analyses, the presence of a protocol in the centre facilitated the management of IS by the general nephrologists.\u0000The management of IS after AFG by French-speaking nephrologists is heterogeneous.
