Background: The percutaneous insertion of a peritoneal dialysis (PD) catheter by a nephrologist offers a plausible alternative to surgical insertion, improving access to dialysis. We report the experience of the paediatric nephrology unit in Dakar, Senegal, initiating PD for children with acute kidney injury (AKI), using a haemodialysis catheter inserted via a modified Seldinger technique. This approach was chosen due to its availability and cost-free provision, addressing resource constraints effectively.

Introduction: Icodextrin enhances ultrafiltration (UF) in patients on peritoneal dialysis (PD) but is restricted to 1 bag/d, according to regulatory authorities. The Double-Icodextrin Dose (DIDo) study is a prospective randomized trial investigating the superiority and safety of using 2 bags/d versus 1 bag/d of icodextrin to extend incremental (3 bags/d) continuous ambulatory PD (CAPD) duration in older incident patients.

Methods: After a 2-month "run-in" period, the patients were randomized to 2 icodextrin ("double dose") + 1 glucose or 1 icodextrin ("single dose") + 2 glucose dialysates daily.

BackgroundKidney impairment (KI) is a frequent complication of multiple myeloma (MM), with chronic kidney disease (CKD) often necessitating dialysis. Peritoneal dialysis (PD) offers quality-of-life advantages over haemodialysis (HD), yet its use in patients with CKD secondary to MM (CKD-MM) remains understudied. This study investigates the characteristics and outcomes of PD in CKD-MM patients compared to those with other kidney diseases.

Introduction: The optimal management of thromboembolism (TE) in patients with nephrotic syndrome (NS) remains challenging. Until now, anticoagulation therapy for NS consisted of vitamin K antagonists (VKAs) or heparin. Data on direct oral anticoagulant (DOAC) use in NS are limited, and their safety and convenience have been well-demonstrated in other indications.

Background: In many parts of the world, heat waves have been associated with excess morbidity and mortality in the general population. Studies on the effects of high-temperature exposure in kidney transplantation are lacking and are scare in dialysis patients. The aim of this study was to investigate the association between high temperatures and mortality for chronic kidney disease (CKD) stage 5 patients treated with dialysis or with a kidney graft in France using various definition of elevated temperature.

Background And Hypothesis: The risk of ischaemic or haemorrhagic strokes in patients living with end-stage renal disease and receiving replacement therapy is more than double that of non-dialysed individuals. Autosomal dominant polycystic kidney disease (ADPKD) is an inherited systemic disorder associated with renal and non-renal manifestations, including intracerebral aneurysms. The role of underlying nephropathy in determining the onset of the stroke is unclear.

Acute kidney injury (AKI) is a common event associated with a high mortality rate in the absence of adequate treatment. In lower-income countries, peritoneal dialysis (PD) plays an essential role in the treatment of AKI, especially in the paediatric population. In 2013, the International Society of Nephrology (ISN) launched the ‘0 by 25’ project, which aims to eliminate preventable deaths from AKI worldwide by 2025.

Objectives: The objective is to investigate the association between antidepressant drugs intake and falls reporting, as well as the potential mediators in-between, in older adults.

Methods: In VigiBase®, the World Health Organization's pharmacovigilance database, we performed a disproportionality analysis to probe the putative associations between each antidepressant drugs class (non-selective monoamine reuptake inhibitors [NSMRIs], selective serotonin reuptake inhibitors [SSRIs], serotonin-norepinephrine reuptake inhibitors [SNRIs], alpha-2-adrenergic receptor antagonists, and "other antidepressants") and reports of falls in people aged 65 and over (NCT05628467). The reporting odds ratios and their 95% confidence interval were derived from logistic regression models with adjustment for confounders.

Key Points: Nurse assistance is associated with a lower risk of transfer to hemodialysis for dialysis inadequacy after 6 months and for infection in the first 18 months. Compared with automated peritoneal dialysis (PD), continuous ambulatory PD is associated with a higher risk of transfer to hemodialysis for mechanical issue during the first 18 months. Suboptimal starters have a higher risk of transfer to hemodialysis due to psychosocial challenges in the first 6 months of PD.

Introduction: Peritonitis occurring within the first months on peritoneal dialysis (PD) has been associated with poorer PD outcomes. Whether early peritonitis is a risk factor for transfer to haemodialysis in the long term is a matter of investigation.

Methods: This retrospective study was conducted using data from the French Language PD Registry of incident PD patients between 2002 and 2018.

Not all patients on dialysis want to be registered on the kidney transplantation (KT) waiting list and undergo transplantation. The aim of this convergent mixed methods study was to determine the features of patients refusing to be registered on the KT waiting list and the reasons. Quantitative data on all 2017-2019 incident 18-85-year-old dialysis patients, eligible for KT, were extracted from the REIN registry in France.

Article Synopsis
  • - This study aimed to investigate how social health inequalities might affect the treatment of adolescent idiopathic scoliosis in the French healthcare system by analyzing the care pathway from diagnosis to post-surgery.
  • - Researchers reviewed data from 883 patients who underwent surgery for scoliosis between 2009 and 2019, focusing on factors like Cobb angle measurements, brace compliance, and surgical outcomes, using regression models to assess socioeconomic influences.
  • - The findings indicated that socioeconomic deprivation had a limited impact on treatment management, with significant effects only observed at the first consultation and on postoperative correction, highlighting the need for improved screening practices and further research on socioeconomic factors.

Key Points: It is unknown whether the benefit of assisted peritoneal dialysis (PD) programs appears immediately after PD initiation or rather after some time spent on PD. The protective effect of assisted PD on the risk of transfer to hemodialysis was not constant over time; it started after the first 6 months on PD. Assisted PD programs should be sustainable for at least 6 months to observe their benefits.

Article Synopsis
  • - The study investigates how serum levels of ceruloplasmin, an inhibitor of myeloperoxidase, affect the prognosis of patients with anti-MPO antibody-positive anti-neutrophil cytoplasmic antibody-associated vasculitis (AAV).
  • - It analyzed data from 92 patients, revealing that those with lower ceruloplasmin levels had a significantly higher death rate (40% vs. 12%) during a median follow-up of 40 months.
  • - The findings suggest that ceruloplasmin levels at diagnosis could be an important marker for survival in patients with anti-MPO AAV, while similar analyses in anti-PR3 antibody patients showed no differences.

Introduction: Several randomised controlled trials have demonstrated that novel oral anticoagulants are safer compared with vitamin K antagonists for the management of non-valvular atrial fibrillation (NVAF) to prevent thromboembolic events in the general population. There is a growing interest in the use of apixaban in patients with end-stage renal disease (ESRD) undergoing peritoneal dialysis (PD) but there is a lack of randomised data in this population.

Methods And Analysis: APIDP2 is a prospective parallel, randomised, open-label, blinded endpoint trial involving patients with ESRD undergoing chronic PD who have NVAF.

Article Synopsis
  • - The study explores how patients with chronic kidney disease (CKD) and nephrologists perceive kidney transplantation (KT) and the disease itself, using semi-structured interviews in France from a diverse patient group and nephrologists chosen by specific criteria.
  • - Six key themes emerged from the interviews, including the emotional toll of CKD, the influence of healthcare relationships on acceptance of treatment, and differing perceptions of KT experiences between men and women.
  • - Findings highlight that the experience of dialysis is often seen as restrictive, and the way patients view kidney transplants can be shaped by their past experiences and gender-related factors, particularly concerning psychological impacts and decisions around living donor transplants.

Article Synopsis
  • Home dialysis therapies like peritoneal dialysis (PD) and home hemodialysis (HHD) enhance patient quality of life but have low prevalence due to short technique survival times.
  • A retrospective study analyzed data from over 17,000 patients in France to compare the risk of transferring to facility-based hemodialysis among those using autonomous PD, nurse-assisted PD, and HHD.
  • The findings indicated no significant differences in transfer risks among the three modalities, suggesting that assisted PD may benefit a wider range of patients than previously thought, especially in France.

Health literacy (HL) is the ability of individuals to access, understand and use health information to improve their health. It is a multidimensional and contextual concept, whose definition has been enriched over time. Considered both as a health risk factor and a skill to be developed by individuals, HL also depends on the healthcare system in which patients have to navigate, and on healthcare professionals’ awareness of this concept.
