Heme-induced kallikrein-kinin system activation in hemolytic uremic syndrome

Aug 5, 2026

The authors investigate the role of heme in activating the kallikrein-kinin system during hemolytic uremic syndrome (HUS) and its interaction with clotting factor XII (FXII). They find that heme induces FXII activation, leading to the degradation of high-molecular-weight kininogen and the release of bradykinin, which may contribute to inflammation in HUS. The study suggests that targeting this pathway could offer potential therapeutic strategies for managing hemolytic diseases.

Better Guidelines, Better Patient Lives: A Sustainable Partnership Model for Integrating Lived Experience into Clinical Guideline Development

Jul 28, 2026

The authors advocate for the systematic integration of lived experience from patients and caregivers into clinical guideline development to enhance relevance and implementation. They propose a structured dual framework, including a Patient and Public Engagement Policy and a Talent Pipeline for Lived Experience, to cultivate this expertise as a professional competency throughout the guideline process. The paper outlines a phased implementation plan aimed at promoting equity and improving health outcomes in kidney care, while also being adaptable for other guideline bodies.

ISN International Expert Forum: Exploring the Nexus of Cardiovascular-Kidney-Metabolic (CKM) Health

Jul 28, 2026

The authors convened an International Expert Forum to explore the interconnectedness of cardiovascular disease, chronic kidney disease, diabetes, and obesity within the Cardiovascular-Kidney-Metabolic (CKM) framework. They aimed to identify effective strategies for risk assessment, lifestyle interventions, and therapeutic approaches to improve outcomes in CKM health, while addressing challenges such as therapeutic inertia and inequities in care access. The discussions emphasized the need for integrated care models and adaptive implementation strategies to enhance the management of CKM conditions globally.

New insights from DAPA-CKD indicate dapagliflozin modulates key pathways related to kidney outcomes

Jul 27, 2026

The authors aimed to elucidate the mechanisms by which dapagliflozin improves kidney outcomes in patients with chronic kidney disease (CKD) by analyzing plasma proteomics. Their findings revealed that dapagliflozin modifies key pathways associated with CKD progression, particularly those related to inflammation and fibrosis, thereby supporting its protective effects on kidney health.

A multi-national study examined the response sustainability to calcineurin inhibitors and long-term kidney survivals in children with genetic podocytopathies

Jul 27, 2026

This study investigates the sustainability of response to calcineurin inhibitors (CNI) and its impact on long-term kidney survival in children with genetic podocytopathies. The authors found that while only a subset of patients achieved a sustained response to CNI, those who did not experience kidney failure, and even those with non-sustained responses had better kidney survival compared to non-responders. These results suggest that CNI treatment may be beneficial for certain children with genetic podocytopathies, warranting further investigation.

Secondary Thrombotic Microangiopathy (TMA) in children- A Central Role for the Glycocalyx

Jul 27, 2026

The authors investigate the role of the endothelial glycocalyx (eGC) in the pathogenesis of secondary thrombotic microangiopathy (TMA) in children, which is more prevalent than primary TMA and often linked to specific diseases or triggers. They propose that damage to the eGC may serve as a critical mechanism connecting various triggers, such as infections and medications, to endothelial injury and complement dysregulation. This review highlights the potential for eGC restoration as a therapeutic target and the need for further research to identify which pediatric patients may benefit from complement blockade.

Early Acute T Cell-Mediated Rejection and Kidney Allograft Outcomes

Jul 27, 2026

The authors aimed to investigate the impact of early acute T cell-mediated rejection (TCMR) on long-term kidney allograft outcomes, particularly its treatment responses and their association with graft survival. They found that TCMR is common and often resistant to treatment, with persistent TCMR significantly linked to worse graft survival, challenging the perception of TCMR as clinically benign. Their results highlight the need for improved monitoring and targeted therapies to address persistent inflammation in kidney transplant patients.

The Teleologic Basis of Kidney Potassium Handling: A Conceptual Review

Jul 27, 2026

This review explores how human kidney potassium handling evolved to manage high potassium loads from a Paleolithic diet, focusing on the molecular mechanisms involved. The authors identify the WNK-SPAK-OSR1 kinase network as a key regulator and discuss how various kidney functions and adaptations, including the "NCC switch" and gut-kidney interactions, prioritize potassium excretion to prevent hyperkalemia. They conclude that despite modern dietary changes, the kidney's capacity to excrete potassium remains crucial for maintaining cellular function and survival.

Evaluation of CD68⁺ macrophages in relation to kidney outcomes in immunoglobulin light-chain amyloidosis

Jul 24, 2026

The authors aimed to evaluate the relationship between CD68⁺ macrophage infiltration in kidney biopsies and kidney outcomes in patients with immunoglobulin light-chain amyloidosis (AL). They found that higher macrophage scores were associated with an increased risk of renal replacement therapy, while amyloid regression correlated with prolonged kidney survival, suggesting that both macrophage infiltration and amyloid burden are important predictors of kidney outcomes in this condition.

Non-HLA antibodies worsen the histological phenotype and prognosis of antibody mediated rejection in kidney allografts

Jul 24, 2026

The authors investigate the role of non-HLA antibodies in the severity and prognosis of antibody-mediated rejection (AMR) in kidney allografts, particularly in cases without donor-specific anti-HLA antibodies. They find that higher levels of non-HLA antibodies correlate with increased microvascular inflammation and worse graft outcomes, suggesting that their detection could enhance AMR classification and risk assessment in transplant patients.
