Hemodialysis (HD) patients are at considerably high risk for vascular access-related blood stream infections (VRBSI) that result in serious complications. Such severe infections are a great deal more frequent with central venous catheters (CVCs) and polytetrafluoroethylene (PTFE) grafts than with arteriovenous fistula (AVF). Nonetheless, the CVCs, though having "undesirable" side effects, remain "unavoidable" for the patients requiring instant dialysis access, as a consequence of the unpredictable course of chronic renal disease. Although early antibiotic treatment should include the coverage for Staphylococcus aureus, the treatment of catheter-related blood stream infections (CRBSI) remains controversial. Antimicrobial- anticoagulant 'locks' have shown promising results in several recent randomized controlled trials in the treatment and prevention of CRBSI. Policy of increasing AVF prevalence beyond 50% is bound to have an enduring positive effect on HD outcomes. Standard infection control measures for hygiene and aseptic handling of CVCs cannot be overemphasized. The catheters with 'bioactive' surface with thrombo-resistant and infection-resistant properties will be available in the near future.

Nephrol Dial Transplant
January 2025
Department of Nephrology, Kidney Transplantation and Dialysis, CHU Lille, University of Lille, Lille, France.
Background And Hypothesis: Unlike X-linked or autosomal recessive Alport Syndrome, no clear genotype/phenotype correlation has yet been demonstrated in patients carrying a single variant of COL4A3 or COL4A4.
Methods: We carried out a multicenter retrospective study to assess the risk factors involved in renal survival in patients presenting a single pathogenic variant on COL4A3 or COL4A4.
Results: 97 patients presenting a single pathogenic variant of COL4A3 or COL4A4 were included.
Sero-molecular prevalence of toxoplasmosis in hemodialysis and peritoneal dialysis patients in Markazi Province, Iran.
Trop Med Health
January 2025
Infectious Diseases Research Center, Arak University of Medical Sciences, Arak, Iran.
Background: Infectious diseases, particularly parasitic infections such as toxoplasmosis, contribute significantly to the morbidity and mortality of hemodialysis patients. Toxoplasma gondii infection poses serious risks, especially to immunocompromised individuals. This study aimed to assess the prevalence of latent toxoplasmosis in dialysis patients in Markazi Province, Iran.

Division of Nephrology, State Key Laboratory of Organ Failure Research, Nanfang Hospital, National Clinical Research Center for Kidney Disease, Southern Medical University, 1838 N Guangzhou Ave, Guangzhou, 510515, China.
Background: Iron deficiency is prevalent in patients with chronic kidney disease (CKD), even in those without anemia. However, the effects of iron deficiency on CKD progression and all-cause mortality in non-dialysis-dependent CKD (NDD-CKD) patients without anemia remain incompletely understood.
Methods: This multicenter retrospective nationwide cohort study included adult patients with non-anemia NDD-CKD from 24 hospitals across China.
Kidney REPLACEment therapies in patients with acute kidney injury and RHABDOmyolysis (ReplaceRhabdo): a pilot trial.
BMC Nephrol
January 2025
Medical Department III, Division of Nephrology, University Hospital Leipzig, Leipzig, Germany.
Background: Rhabdomyolysis is frequently associated with acute kidney injury (AKI). Due to the nephrotoxic properties of myoglobin, its rapid removal is relevant. If kidney replacement therapy (KRT) is necessary for AKI, a procedure with effective myoglobin elimination should be preferred.

Reports of glomerulonephritis associated with lymphoproliferative disorders are common, but reports of minimal change disease (MCD) accompanying non-Hodgkin's lymphoma are rare. Here, we present a case of a 45-year-old woman diagnosed with primary Waldenström's macroglobulinemia (WM) during MCD treatment. Her kidney biopsy revealed endothelial cell injury in parts of the MCD.
