About

Managing patients with renal failure requires an understanding of the molecular mechanisms that lead to its occurrence (i.e. upstream of the disease), its worsening and its persistence (i.e. downstream), while also specifying the risk of worsening renal failure (risk stratification, intolerance to the treatment or complications (infectious, metabolic, cardiovascular, cancer...). Nephrogene 2.0 aims to study these different components of kidney, immune and solid organ transplantation (SOT)-related diseases.

Full description

Acute renal failure (ARF) and chronic kidney disease (CKD) are frequent pathologies (850 million people are affected worldwide). Renal failure is associated with an increased morbidity and mortality, including an increased risk of infections, drug toxicity and cardiovascular death. The causes of renal failure are numerous: metabolic (diabetes, hypertension), immunological (autoimmune diseases, monoclonal gammopathies), toxic (environment, drugs), genetic, infectious, ischemic, paraneoplastic... Any episode of ARF is also accompanied by a risk of secondary CKD (relative risk multiplied by 9).

The mechanisms leading to renal failure are multiple and combine predisposing genetic factors, inadequate intra-renal or systemic immune response, endothelial and epithelial dysfunctions, and potentially inappropriate regenerative capacity. In addition, renal failure or its treatment itself may be accompanied by additional renal lesions (e.g. nephrotoxicity of calcineurin inhibitors used as anti-rejection treatment in transplantation, hemodynamic intolerance with secondary ARF during hemodialysis sessions, iatrogenic ARF when using diuretics or inhibitors of the renin angiotensin system) or extra-renal complications (e.g. immunosuppression and infections induced by immunomodulatory therapies during autoimmune diseases or for prevention of transplant rejection; vascular diseases secondary to phosphocalcic disorders).

Patients included in the NEPHROGENE 2.0 cohort will be followed during 10 years and clinical data and biological samples will be collected at the inclusion in the cohort, at each monitoring programmed in their usual care and and at each event (infection, acute kidney injury, cancer...). Samples will be collected according to the symptoms of the patients.
