Chronic kidney disease (CKD) characterized by long duration, simplicity at beginning versus complexity at advanced stages. Hemodialysis and peritoneal dialysis are renal replacement therapy allowing life extension, but comorbidities and frailty could be burdensome over time. The academic society, Société Francophone de Néphrologie, Dialyse, Transplantation (SFNDT), publishes clinical practice guidelines to optimize CKD treatment in this context, to support shared decision-making in the appropriate initiation of and withdrawal from dialysis, and to supervise end-of-life cares in the French-speaking countries.

New Caledonia is a French territory located in the South Pacific Ocean. The prevalence rate of end-stage renal disease is nearly 3,000 per million inhabitants, making it one of the highest prevalence rates in the world. Preventing chronic kidney disease is a major public health issue. This article presents prevalence rates of chronic kidney disease (CKD) stages 3-5 for New Caledonia defined by a glomerular filtration rate estimated below 60 mL/min/1.73 m2. Estimation was assessed from data collected during two “Adult health barometer” surveys carried out in the general adult population. Therefore, our study assessed two prevalence rates: 7.8% [6.1; 10.1] and 5.3% [3.3; 8.5]. Those prevalence rates were two to four times higher than in mainland France which is consistent with the high prevalence rate of end stage renal disease treated in New Caledonia. Hence, CKD prevention is essential for New Caledonia.

Introduction: We have launched a pilot study, called DIADIDEAL, to propose nurse-assistance at home for arterio-venous fistula (AVF) cannulation in home hemodialysis (HHD) patients. The aim of the present study was to describe enrollment of the patients and their nurses.

Materials: All prevalent HD patients on 30th November 2018 with no medical contraindication to HDD treatment and all incident patients on dialysis from the 30th November 2018 to the 21st April 2023 were eligible.

Results: Among 155 prevalent HD patients, 4 patients were included. Among the 276 incident patients on dialysis during the study period, 6 were included. We have phoned 23 nurse centers during the recruitment period. Eight of them agreed to learn in our unit how to cannulate AVF; 27 private nurses were enrolled.

Discussion: The results of the DIADIDEAL study will be available in 2024; we hope it will lead to a reimbursement of nurse-AVF cannulation at home in HDD.

Introduction: Difelikefalin is to date the first and only specific treatment to be approved for the treatment of moderate-to-severe chronic kidney disease-associated pruritus (CKD-aP) in adult patients on hemodialysis.

Patients and methods: This was a retrospective, single-center, real-life study in hemodialysis patients with CKD-aP treated with difelikefalin. The primary objective was to evaluate the evolution of the intensity of pruritus during treatment with difelikefalin using the Worst Itch Intensity-Numerical Rating Scale (WI-NRS). Adult patients were included if they had been on hemodialysis for at least 3 months and were suffering from moderate to severe CKD-aP (objectified by the WI-NRS score) for which difelikefalin had been prescribed.

Results: 11 patients (7 men and 4 women; mean age, 63.8 years) with a mean (SD) weekly dialysis time of 13 h (2.4) were included. The mean hemodialysis duration was 5 (3.6) years and the mean pruritus duration was 4.3 (3.2) years. At inclusion, on-going treatments of CKD-aP were emollients in all patients and antihistamines in 9 patients. The mean WI-NRS score was 7.4 (1.1) at initiation of difelikefalin. At last assessment after a median follow-up of 9.0 months, the mean change of WI-NRS score was -5.1 (2.9) and 82% of patients had a decrease ≥ 3 points. Mild to moderate adverse reactions to difelikefalin were reported in 4 patients, all of whom recovered without sequelae.

Conclusion: These results show that difelikefalin, prescribed according to its therapeutic indication, is effective in the treatment of CKD-aP under real-life conditions, outside the controlled conditions of a clinical trial.

The management of patients with kidney transplant failure (KTF) remains a complex process involving multiple stakeholders. 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.We 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.The management of IS after AFG by French-speaking nephrologists is heterogeneous. Specific prospective studies are needed to establish new best practice recommendations, based on more robust evidence, which could encourage better adherence by nephrologists.

Historically, it takes an average of 17 years to move new treatments from clinical evidence to daily practice. Given the highly effective treatments now available to prevent or delay kidney disease onset and progression, this is far too long. The time is now to narrow the gap between what we know and what we do. Clear guidelines exist for the prevention and management of common risk factors for kidney disease, such as hypertension and diabetes, but only a fraction of people with these conditions worldwide are diagnosed, and even fewer are treated to target. Similarly, the vast majority of people living with kidney disease are unaware of their condition, because in the early stages it is often silent. Even among patients who have been diagnosed, many do not receive appropriate treatment for kidney disease. Considering the serious consequences of kidney disease progression, kidney failure, or death, it is imperative that treatments are initiated early and appropriately. Opportunities to diagnose and treat kidney disease early must be maximized beginning at the primary care level. Many systematic barriers exist, ranging from patient to clinician to health systems to societal factors. To preserve and improve kidney health for everyone everywhere, each of these barriers must be acknowledged so that sustainable solutions are developed and implemented without further delay.

Introduction: Medication non-adherence is a global concern, particularly in the context of renal transplantation, where it leads to graft failures, increased hospitalizations, diminished quality of life for patients, and higher healthcare costs. The aim of this study was to assess the level of therapeutic adherence among Algerian kidney transplant recipients and identify potential influencing factors.

Methods: A descriptive, cross-sectional bicenter study was conducted among kidney transplant patients receiving outpatient care at two specialized medical centers in Algeria: the Urology Department of the Hospital Establishment for Urology, Nephrology, and Renal Transplantation in Constantine, and the Nephrology and Renal Transplantation Department of the University Hospital Center (CHU) in Blida, spanning from January to December 2022. Therapeutic adherence was assessed using the 8-item Morisky questionnaire, while the level of knowledge was analyzed through a 12-item questionnaire. Logistic regression was used to identify factors associated with non-adherence to therapy.

Results: This study included 130 patients with an average age of 47 years and a sex ratio of 1.7. The results revealed therapeutic non-adherence in 40.8% of the patients. Multivariate analysis identified several potentially associated factors, including residence, unemployment status, lack of affiliation with a health insurance fund, the use of a therapeutic regimen involving triple therapy, the occurrence of adverse effects, limited education level, and insufficient disease knowledge. Furthermore, non-adherence was associated with an increased risk of graft rejection.

Conclusion: The findings of this study highlight concerning therapeutic adherence among kidney transplant recipients, emphasizing the crucial importance of therapeutic education to improve treatment adherence and underscoring the need to integrate these factors into clinical patient management.

Introduction: Pre-emptive access to the kidney transplant (KT) waiting list remains limited in France, with only 3.9% of patients on pre-emptive KT and 5.6% of patients registered at the time of initiation of dialysis. A similar trend was observed in Aquitaine. The aim of this study was to assess the impact of a regional program in terms of access to the waiting list for patients initiating a kidney replacement therapy (KRT).

Methods: We included all patients assessed for registration on the list between 2017 and 2020, 2017 being the reference year and 2018 the beginning of the program. Using the CRISTAL and REIN registries, we assessed changes in the number of patients on the list at the time of initiation of dialysis or transplantation.

Results: The number of new assessed candidates increased gradually each year from 255 in 2017 to 352 in 2020 (+38%). The number of patients on the list sharply increased in 2018 from 229 in 2017 to 319 in 2018 (+39.3%) and then remained stable. At the initiation of KRT, the proportion of patients registered on the waiting list increased gradually from 7.1% in 2017 to 18.2% in 2020. The proportion of pre-emptive KT remained stable between 2017 and 2021 (around 7%) with a decrease in 2020 (4.6%). Approximately 60% of patients had a contraindication to transplantation throughout the study.

Conclusion: This study showed that a regional program aimed at providing better information to healthcare professionals and patients and encouraging rapid assessment of transplant candidates could increase the rate of pre-emptive registration on the KT waiting list for eligible patients over 4 years.
