Introduction: Urinary albumin-to-creatinine ratio (uACR) is an independent predictor of chronic kidney disease (CKD) progression. However there is limited evidence on the burden of CKD according to uACR categories at the population level. This study estimates future clinical and financial burden of CKD according to uACR categories using the Inside CKD microsimulation.

Background: Hypertension is the most common chronic disease and a major modifiable risk factor for cardio-cerebrovascular and renal diseases. This study estimated the national burden of hypertension, defined as systolic blood pressure ≥140 mm Hg, on morbidity and mortality in 2021 in France.

Methods: For all diseases causally associated with hypertension (cardiovascular diseases, chronic kidney diseases, and dementia), the number and proportion of cases attributable to hypertension in adults aged ≥35 years were estimated using population attributable fractions.

Article Synopsis
  • Cardiovascular disease is the leading cause of death globally and a major concern in France, heavily influenced by modifiable risk factors like obesity, diabetes, hypertension, and high cholesterol levels.
  • In 2015, significant prevalence rates for these conditions were reported among adults aged 18-74, with obesity at 17.2% and diabetes at 7.4%, yet awareness of these conditions was low among those affected.
  • A push for better prevention methods, especially through nutrition and education, is essential to tackle these cardiovascular risk factors, with a noted importance on also addressing women's specific health issues that impact cardiovascular risk.

Objective Real-life management of patients with hypertension and chronic kidney disease (CKD) among European Society of Hypertension Excellence Centres (ESH-ECs) is unclear : we aimed to investigate it. Methods A survey was conducted in 2023. The questionnaire contained 64 questions asking ESH-ECs representatives to estimate how patients with CKD are managed.

: Cardiorenal syndrome (CRS) is a disorder of the heart and kidneys, with one type of organ dysfunction affecting the other. The pathophysiology is complex, and its actual description has been questioned. We used clustering analysis to identify clinically relevant phenogroups among patients with CRS.

Article Synopsis
  • - A 2023 survey by the European Society of Hypertension assessed the management of chronic kidney disease (CKD) patients with hypertension across 88 centers in 27 countries, finding that only 28% had preexisting CKD, and 30% exhibited resistant hypertension.
  • - The survey indicated inconsistent rates of recent kidney function tests and varying usage of important medications, showing higher rates of certain drugs when nephrologists were involved in the care team.
  • - Overall, the study highlighted significant gaps in CKD screening and treatment prior to referral for specialized care, suggesting that tailored initiatives could enhance management for patients with hypertension and CKD.

Background: Carfilzomib, a new proteasome inhibitor indicated for patients with relapsed/refractory myeloma, has been associated with cases of thrombotic microangiopathy (CFZ-TMA). The role of variants in the complement alternative pathway and therapeutic potential of complement blockade with eculizumab remain to be determined.

Methods: We report 37 cases of CFZ-TMA recorded in the French reference center for TMA with their clinical characteristics, genetic analysis and outcome according to treatments.

Thrombotic microangiopathies (TMA) are usually associated with hematological features (RH-TMA). The epidemiology of TMA limited to kidneys (RL-TMA) is unclear Therefore, patients with TMA and native kidney biopsies were identified during 2009-2022 in 20 French hospitals and results evaluated. RL-TMA was present in 341/757 (45%) patients and associated with lower creatinine levels (median 184 vs 346 μmol/L) than RH-TMA.

Article Synopsis
  • Eculizumab is a medicine used to treat certain kidney diseases, and scientists want to find a better way to give the right amount to patients, avoiding high doses that can be costly.
  • They studied blood samples from 44 patients to understand how the drug leaves the body and whether a new model can predict its levels better than a simple one.
  • The results showed that how eculizumab is eliminated from the body isn’t straightforward and depends on the person’s weight, which helps doctors decide the best dose for each patient.

Article Synopsis
  • In June 2023, the European Society of Hypertension released new guidelines for managing arterial hypertension, which were also endorsed by the European Renal Association.
  • The guidelines provide updated recommendations for managing hypertension in patients with chronic kidney disease, including specific target blood pressures and medication strategies.
  • Key recommendations involve using certain diuretics for resistant hypertension, advising against overly low blood pressure targets, and identifying treatment options for patients with CKD and related conditions.

Article Synopsis
  • This study analyzed the impact of gender on adult IgA vasculitis (IgAV) by examining data from 260 patients across multiple centers.
  • Results showed that while baseline symptoms were similar between males and females, males experienced more severe kidney involvement, indicated by lower kidney function and higher protein levels in urine.
  • Male patients also received more aggressive treatments but had a higher rate of refractory disease, suggesting gender could be a significant prognostic factor in the disease's progression.

The association between cardiac and kidney dysfunction has received attention over the past two decades. A putatively unique syndrome, the cardiorenal syndrome, distinguishing five subtypes on the basis of the chronology of cardiac and kidney events, has been widely adopted. This review discusses the methodologic and practical problems inherent to the current classification of cardiorenal syndrome.

Introduction: Previous studies have suggested that genetic kidney diseases in adults are often overlooked, representing up to 10% of all cases of chronic kidney disease (CKD). We present data obtained from exome sequencing (ES) analysis of patients with biopsy-proven undetermined kidney disease (UKD).

Methods: ES was proposed during routine clinical care in patients with UKD from January 2020 to December 2021.

Atherosclerotic cardiovascular disease (ASCVD) is the leading cause of mortality and morbidity in individuals with type 2 diabetes mellitus (T2DM). Accordingly, several scientific societies have released clinical practice guidelines to assist health professionals in ASCVD risk management in patients with T2DM. However, some recommendations differ from each other, contributing to uncertainty about the optimal clinical management of patients with T2DM and established ASCVD or at high risk for ASCVD.

Diabetes is the leading cause of end-stage kidney disease (ESKD), accounting for approximately 50% of patients starting dialysis. However, the management of these patients at the stage of chronic kidney disease (CKD) remains poor, with fragmented care pathways among healthcare professionals (HCPs). Diagnosis of CKD and most of its complications is based on laboratory evidence.

Background: The worldwide development of immune system targeting/anticancer drugs has revolutionized immuno-oncology, but their implication in thrombotic microangiopathy syndromes (TMA) is increasingly suspected. Using real-world data, the aim of this study was to identify drugs associated with TMA reporting and to describe the evolution of TMA reporting over time with a focus on these drugs.

Methods: A global disproportionality study was performed using the individual case safety reports (ICSRs) extracted from the World Health Organization (WHO) pharmacovigilance database (VigiBase) from its inception (1968) to April 30, 2022.

Background And Objectives: Activation of the complement system is involved in the pathogenesis of anti-glomerular basement membrane (anti-GBM) disease. Glomerular deposits of complement 3 (C3) are often detected on kidney biopsies. The primary objective of this study was to analyze the prognostic value of the serum C3 level and the presence of C3 glomerular deposits in patients with anti-GBM disease.

IgA vasculitis (IgAV) is a small size vasculitis for which epidemiologic data are strikingly lacking, especially about the adult form. Additionally, the COVID-19 pandemic seems to have profoundly modified the incidence of this disease. Here, we aimed to establish some relevant epidemiological data in both pediatric and adult IgAV.
