The overlap between oncology and nephrology is an area of growing importance. A major reason for this is that less than half the patients with cancer were long-term survivors years ago, whereas now more than two-thirds will live 5 years or longer. Late effects of cancer treatment include nephrotoxicity and are part of current clinical practice. In addition, cancer is now a known feature of chronic kidney disease (CKD), with increased risk in patients receiving dialysis or with a functioning kidney transplant, as well as those with earlier stages of the disease. Therefore, oncologists will refer patients to nephrologists, and nephrologists will need to consult oncologists. This Core Curriculum addresses the key issues at this challenging clinical interface.

High prevalence of the problem in part due to ageing with CKD - Consequences for the patient and the economy of health - Danger of CKD development or aggravation, mortality Need for early diagnosis (new biomarkers?) but not yet proof of efficacy for prevention. Useful for predicting prognosis? Prevention first: interval between contrast agents use and surgery, caution about medical therapy, fluid volume balance, importance of the kind of solution used, quality of the CBP! Treatment: avoid complications when AKI installed, nutrition ! Early RRT (?)(rapid uremic control or fluid balance?) but high mortality even after hospital discharge (max 1/3 survival at 1 y) [less ▲]

Le lupus érythémateux disséminé (LED) est une maladie de système aux conséquences aussi multiples qu’invalidantes. La prévalence des épisodes dépressifs majeurs y est significativement supérieure à celle des sujets sains ou atteints d’autres pathologies inflammatoires. S’il est évident que le statut de maladie chronique au dénouement souvent péjoratif et le nombre de traitements qu’elle impose constituent des facteurs favorisants, il est probable que les mécanismes pathogéniques du LED occasionnent une atteinte cérébrale précipitant une symptomatologie dépressive. Cet article approfondit les liens entre LED et dépression à travers des notions épidémiologiques, étiopathogéniques et thérapeutiques. [less ▲]

Hypophosphatemia is defined by a serum phosphate level lower than 0.8 mmol/l. If hypophosphatemia is chronically maintained, it is associated with muscular, osteous, neurological or cardio-respiratory disorders. We describe a patient with isolated hypophosphatemia, detail the mechanisms of phosphate homeostasis, and envisage the differential diagnosis of hypophosphatemia. Furthermore, we propose a sequential decisional algorithm based on basic biological tests and few complementary investigations. Treatment options are reviewed. [less ▲]

Acute cardiorenal syndrome (CRS) corresponds to an association of acute heart failure and a worsening of renal function. The detection of acute kidney injury (AKI) unfortunately occurs at a late stage of CRS, leading to an increased mortality of the patients. In this review, we described the pathophysiology of CRS and discussed the potential interest of biochemical biomarkers (namely creatinine, cystatin C, NGAL, KIM-1, fatty acid binding protein, Nacetyl-β-D-glucosaminidase and IL-18) that could potentially help to detect AKI earlier and thus reduce the morbi-mortality of the patients suffering from CRS.

Chronic kidney disease is frequent and usually responsible of mineral and bone disorder. These abnormalities lead to increased morbidity and mortality. To become active, native vitamin D needs a first hydroxylation in the liver, and a second one in the kidney. Next to its action on bone metabolism, vitamin D also possesses pleiotropic actions on cardiovascular, immune and neurological systems as well as antineoplastic activities. End-stage renal disease (ESRD) is also associated with a decrease in vitamin D activity by mechanisms including the increase of plasma phosphate concentration, secretion of FGF- 23 and decrease in 1a-hydroxylase activity. The prevalence of 25 hydroxy-vitamin D deficiency depends on the chosen cut-off value to define this lack. Currently it is well established that a patient has to be substituted when 25 hydroxy-vitamin D level is under 30 ng/mL. The use and monitoring of 1.25 hydroxy-vitamin D is still not recommended in routine practice. The goals of vitamin D treatment in case of ESRD are to substitute the deficiency and to prevent or treat hyperparathyroidism. Interest of native vitamin D in first intention is now well demonstrated. This review article describes the vitamin D metabolism and physiology and also the treatment for vitamin D deficiency in ESRD population. [less ▲]

Activation of the calcium-sensing receptor (CaSR) by ischemia/reperfusion (I/R) favours apoptosis in cardiomyocytes, hepatocytes and neurons. Its role in renal I/R is unknown. We investigated the impact of pharmacological preactivation of the CaSR on kidney structure and function in a murine model of bilateral renal 30-min ischemia and 48-hour reperfusion, and in a 6-year cohort of kidney transplant recipients (KTR). C57BL/6J mice were administered daily with CaSR agonist, R-568, or with vehicle for 48 hours. Evaluation of serum urea and creatinine levels, renal histology and urine metabolome by nuclear magnetic resonance showed that R-568 was not nephrotoxic per se. Following I/R, serum urea and creatinine levels increased higher in R-568-treated animals than in controls. Jablonski’s score was significantly greater in R-568-treated kidneys, which showed a higher rate of cell proliferation and apoptosis in comparison to controls. Next, we retrospectively identified 36 patients (10.7% of our cohort) who were treated by CaSR agonist, cinacalcet, at the time of kidney transplantation (KTx). After matching these to 61 KTR upon type of donor, cold ischemic time, residual diuresis, and donor age, we observed that delayed graft function, i.e. need for dialysis in the first week after KTx, occurred in 42 and 23% of cinacalcet-treated and control groups, respectively (p≤0.05). These data suggest that pharmacological preactivation of the CaSR before renal I/R exacerbates kidney injury. [less ▲]

The diabetic kidney disease is the most frequent cause of end stage renal disease in Western countries. Its detection is obtained by simultaneously measuring urinary albumin excretion and estimating glomerular filtration rate through serum creatinine dosage. Many type 1 and type 2 diabetic patients can present decreased glomerular filtration rate before the occurrence of increased urinary albumin. While waiting for promising new pharmacological approaches currently evaluated in clinical trials, the best approach to stop the epidemic of diabetic nephropathy remains an early and individual multifactorial approach controlling the glucose level (without inducing hypoglycaemia), blood pressure (using a renin-angiotensin blocker), dyslipidaemia and over-weight.

Ischemia/reperfusion injury (IRI) represents a worldwide public health issue of increasing incidence. IRI may virtually affect all organs and tissues and is associated with significant morbidity and mortality. Particularly, the duration of blood supply deprivation has been recognized as a critical factor in stroke, hemorrhagic shock, or myocardial infarction, as well as in solid organ transplantation (SOT). Pathophysiologically, IRI causes multiple cellular and tissular metabolic and architectural changes. Furthermore, the reperfusion of ischemic tissues induces both local and systemic inflammation. In the particular field of SOT, IRI is an unavoidable event, which conditions both short- and long-term outcomes of graft function and survival. Clinically, the treatment of patients with IRI mostly relies on supportive maneuvers since no specific target-oriented therapy has been validated thus far. In the present review, we summarize the current literature on mesenchymal stromal cells (MSC) and their potential use as cell therapy in IRI. MSC have demonstrated immunomodulatory, anti-inflammatory, and tissue repair properties in rodent studies and in preliminary clinical trials, which may open novel avenues in the management of IRI and SOT.

BACKGROUND: Adult cardiac surgery is significantly associated with the development of acute kidney injury (AKI). Still, the incidence and outcomes of AKI vary according to its definition. Our retrospective monocentric study comparatively investigates the yield of RIFLE definition, which is based on the elevation of serum creatinine levels (SCr) or the reduction of urine output (UO), taking into account only one or both criteria. Pre- and per-operative risk factors for post-operative AKI were evaluated. METHODS: All adult patients undergoing cardiac surgery, with or without cardiopulmonary bypass, from April 2008 to March 2009 were included. Clinical, biological and surgical features were recorded. Baseline serum creatinine was determined as its value on day 7 before surgery. Post-operative AKI was diagnosed and scored based upon the highest serum creatinine and/or the lowest urine output. RESULTS: 443 patients (Male/Female ratio, 2.3; median age, 69y) were included, with 221 (49.9 %) developing postoperative AKI. Elevated serum creatinine (AKISCr) and oliguria (AKIUO) was observed in 9.7 % and 40.2 %, respectively. AKI patients had a significantly higher BMI and baseline SCr. In comparison to AKIUO, AKISCr mostly occurred in patients with co-morbidities, and was associated with an increased mortality at 1-year post surgery. CONCLUSIONS: The use of standard RIFLE definition of AKI in a cohort of 443 patients undergoing cardiac surgery resulted in an incidence reaching 50 %. Still, significant discrepancies were found between AKISCr and AKIUO regarding the incidence and outcomes. In line with previous reports, our data questions the utility of urine output as a criterion for AKI diagnosis and management after cardiac surgery. [less ▲]

Hypertension has a high world-wide prevalence, affecting more than 25 % of the population; it remains the silent killer number one in cardiovascular pathology. Although lowering high blood pressure is protective, perfect control of hypertension is far from being optimal in spite of many international guidelines regularly updated according to published scientific studies. A personalized approach of hypertension management is an attractive way to improve this situation. Tools are developing (pharmacogenetics, pharmacometabolomics), but their use in daily clinical practice seems premature. At the present time, it is the physician experience which offers the best opportunity to propose the best treatment to the best patient. The management of hypertension remains a difficult task in some cases. [less ▲]
