Clinical Presentation, Pathological Spectrum, and Outcomes of Alcoholic Cirrhosis-Related Immunoglobulin A Nephropathy.

Introduction: Immunoglobulin A nephropathy (IgAN) associated with cirrhosis is frequent but often overlooked because it is largely considered silent. Until now, little has been known about their presentation and outcomes.

Methods: We conducted a retrospective multicenter study on patients with kidney biopsy-proven cirrhosis-related IgAN (cirrhosis-IgAN), diagnosed between 2009 and 2022.

Incidence, Risk Factors and Outcomes of Kidney and Liver Cyst Infection in Kidney Transplant Recipient With ADPKD.

Introduction: Cyst infection is a known complication of autosomal dominant polycystic kidney disease (ADPKD). Here, we describe incidence, risk factors, clinical presentation, and outcomes of cyst infection in kidney transplant recipient.

Methods: We conducted a single-center retrospective cohort study of patients with ADPKD with renal allografts between January 1, 2009, and October 31, 2020.

Disease Activity and Adverse Events in Patients with ANCA-Associated Vasculitides Undergoing Long-Term Dialysis.

Background And Objectives: Kidney impairment of ANCA-associated vasculitides can lead to kidney failure. Patients with kidney failure may suffer from vasculitis relapses but are also at high risk of infections and cardiovascular events, which questions the maintenance of immunosuppressive therapy.

Design, Setting, Participants, & Measurements: Patients with ANCA-associated vasculitides initiating long-term dialysis between 2008 and 2012 in France registered in the national Renal Epidemiology and Information Network registry and paired with the National Health System database were included.

Dynamic predictions of long-term kidney graft failure: an information tool promoting patient-centred care.

Background: Informing kidney transplant recipients of their prognosis and disease progression is of primary importance in a patient-centred vision of care. By participating in decisions from the outset, transplant recipients may be more adherent to complex medical regimens due to their enhanced understanding.

Methods: We proposed to include repeated measurements of serum creatinine (SCr), in addition to baseline characteristics, in order to obtain dynamic predictions of the graft failure risk that could be updated continuously during patient follow-up.

Comparison of graft and patient survival according to the transplantation centre policy for 1-year screening biopsy among stable kidney recipients: a propensity score-based study.

Background: The clinical utility of screening biopsies (SBs) at 1 year post-transplantation is still debated, especially for stable kidney graft recipients. Given the heterogeneity in practices between transplantation centres, the objective of this study was to compare graft and patient survival of stable patients according to whether they were followed up in a transplantation centre with or without a policy for having an SB at 1 year post-transplantation.

Materials: From a French multicentre cohort, we studied 1573 kidney recipients who were alive with stable graft function at 1 year post-transplantation, with no acute rejection in their first year post-transplantation.

The 1-year Renal Biopsy Index: a scoring system to drive biopsy indication at 1-year post-kidney transplantation.

Surveillance biopsies after renal transplantation remain debatable. To drive the decision of such intervention, we propose a predictive score of abnormal histology at 1-year post-transplantation, named 1-year Renal Biopsy Index (1-RBI). We studied 466 kidney recipients from the DIVAT cohort alive with a functioning graft and a surveillance biopsy at 1-year post-transplantation.

Rabbit antithymocyte globulin-induced serum sickness disease and human kidney graft survival.

Background: Rabbit-generated antithymocyte globulins (ATGs), which target human T cells, are widely used as immunosuppressive agents during treatment of kidney allograft recipients. However, ATGs can induce immune complex diseases, including serum sickness disease (SSD). Rabbit and human IgGs have various antigenic differences, including expression of the sialic acid Neu5Gc and α-1-3-Gal (Gal), which are not synthesized by human beings.

[Prospective study of drug-induced interstitial nephritis in eleven French nephrology units].

Objective: Certain medications have been associated with drug-induced acute interstitial nephritis (AIN), but few prospective studies have been published. This prospective observational study aims to record and assess incidents of drug-induced AIN observed over a period of one year in nephrology units in France. The goal is to determine which medications are involved in AIN and to expound the clinical and biological presentation, management, and evolution of AIN.

Differential modulation of donor-specific antibodies after B-cell depleting therapies to cure chronic antibody mediated rejection.

Background: Donor-specific antibodies (DSA) are considered as reliable biomarkers for antibody-mediated rejection (ABMR) diagnosis. However, it is unclear whether DSA monitoring is necessary and could predict graft outcome after antirejection treatment.

Methods: We analyzed 28 non-sensitized kidney transplant patients with ABMR associated with de novo anti-human leukocyte antigen (HLA) DSA.

The spectrum of renal involvement in patients with inflammatory myopathies.

Data regarding the incidence and outcome of renal involvement in patients with inflammatory myopathies (IM) remain scarce. We assessed the incidence and causes of acute kidney injury (AKI) and chronic kidney disease (CKD) in 150 patients with dermatomyositis, polymyositis, and antisynthetase syndrome followed in 3 French referral centers. Renal involvement occurred in 35 (23.
