L'hypertension artérielle est fréquemment observée chez le patient diabétique de type 2 et aggrave le pronostic cardio-vasculaire et rénal. Abaisser la pression artérielle représente donc un objectif essentiel dans cette population. Cependant, les valeurs de pression systolique et diastolique à atteindre restent controversées et la cible doit sans doute être ajustée en fonction des caractéristiques individuelles du patient ("médecine personnalisée"). Cette vignette clinique résume les principaux arguments à propos du choix des cibles tensionnelles, en termes de rapport bénéfices/risques, selon que le patient diabétique présente un syndrome métabolique sans complications, une néphropathie ou une insuffisance coronaire.

Renal transplantation from living kidney donors is still relatively marginal in most of the European countries. However, this source of kidney grafts may help to overcome in part the organ donor shortage of cadaveric donors. The living donor strategy implies correct and objective information about donation risks and completely free acceptance of the living candidate of the donation. In this paper, we reviewed the consequences of kidney donation on the living donor health, considering very short term (linked to the surgery), short term (effect of nephrectomy on glomerular filtration rate) and long term (risk of mortality, chronic kidney disease, proteinuria and hypertension) consequences of kidney donation.

Essential hypertension, defined as a blood pressure equal to or above 140/90 mmHg, is a common (25% of the population), but complex disease the phenotype of which results from interactions between numerous genes and environmental factors. The role attributable to genetic factors amounts to some 25% among hypertensive families, but can reach 65% when monozygotic twins are compared. In the present state of our knowledge, there is no hope to obtain a genetic test of value for the diagnosis and prognosis of hypertension. An individualized environmental approach, applied early in life, is the only worhtwhile attitude. Nonetheless, in the presence of a subject with still normal blood pressure values, but with a family history of hypertension, the physician should firmly recommend an appropriate hygieno-dietetic lifestyle with a view to lower blood pressure, or retard the development of arterial hypertension [less ▲]

The blockade of the renin-angiotensin system (RAS) improves the prognosis of patients with complications related to diabetes, hypertension or, in general, atherosclerosis. Several observational studies have suggested the use of a dual blockade of the RAS to benefit from a better cardiorenal protection. However, recent randomized controlled studies failed to demonstrate that a dual blockade exert a better protection than single blockade, but showed a higher risk for renal complications and hyperkalemia. To decrease the residual risk, other opportunities may be recommended such as reinforcement of low salt diet, use of supraphysiological dose of a monotherapy inhibiting the RAS (perhaps prescribed at the evening) or addition of an aldosterone antagonist. However, all these approaches, as dual therapy, may also increase the risk of hypotension and renal insufficiency and thus require to be used under strict medical supervision. [less ▲]

INTRODUCTION: Delayed graft function (DGF) occurs more frequently in kidney transplants from donation after cardiac death (DCD) than from donation after brain death (DBD). We investigated the effect of DGF on posttransplantation outcomes among grafts from controlled DCD kidneys. PATIENTS AND METHODS: This single-center retrospective study recruited 80 controlled DCD kidneys transplanted from January 2005 to December 2011. Mean patient follow-up was 28.5 months. RESULTS: There were no primary nonfunction grafts; the DGF rate was 35.5%. Overall graft survival rates between groups with versus without DGF were 92.4% and 95.2% at 1 year, 92.4% and 87.1% at 3 years, and 84.7% and 87.1% at 5 years, respectively (P = not significant (NS)). Patients with versus without DGF showed the same survival rates at the corresponding time 92.4% vs 97.2%, 92.4% vs 93.9%, and 84.7% vs 93.9% (P = NS). Estimated glomerular filtration rate was significantly lower in the DGF compared with the non-DGF group at hospital discharge (29 vs 42 mL/min; P = .00) and at 6 months posttransplantation (46 vs 52 mL/min; P = .04), but the difference disappeared thereafter: 47 vs 52 mL/min at 1 year, 50 vs 48 mL/min at 3 years, and 54 vs 53 mL/min at 5 years (P = NS). DGF did not increase the risk of an acute rejection episode (29.6% vs 30.6%; P = NS) or rate of surgical complications (33.3% vs 26.5%; P = NS). However, DGF prolonged significantly the length of hospitalization in the DGF versus the non- DGF group (18.9 vs 13 days; P = .00). Donor body mass index (BMI) >/= 30 kg/m(2), recipient BMI >/=30 kg/m(2), and pretransplantation dialysis duration increased the risk of DGF upon multivariate logistic regression analysis. CONCLUSIONS: Apart from the longer hospital stay, DGF had no deleterious impact on the future of kidney allografts from controlled DCD, which showed comparable graft and patient survivals, renal function, rejection rates, and surgical complications as a group without DGF. Therefore, DGF should no longer be considered to be a medical barrier to the use of kidney grafts from controlled DCD. [less ▲]

Anorexia nervosa is a common psychiatric disorder that disproportionately affects adolescents and young adults and is associated with high rates of morbidity and mortality. Anorexia nervosa can affect the kidney in numerous ways, including increased rates of acute kidney injury and chronic kidney disease, electrolyte abnormalities, and nephrolithiasis. Additionally, the diagnosis and treatment of anorexia nervosa–associated kidney diseases are challenging, reflecting complications such as refeeding syndrome, as well as the limitations of serum creatinine level in this population to estimate kidney function and the psychosocial challenges inherent with treating systemic manifestations of psychiatric conditions. In this review, we discuss kidney diseases and kidney-associated conditions that occur in individuals with anorexia nervosa, summarizing many of the challenges in treating patients with this disease [less ▲]

Both diabetes mellitus and arterial hypertension are commonly observed in a single patient. However, the relationship between these two entities is rather complex and there is a great heterogeneity regarding the underlying pathophysiological mechanisms and the clinical presentations. These particularities may have important consequences from a therapeutic point of view, as far as blood pressure targets or even pharmacological strategies are concerned. The present article will discuss the various causes of hypertension in the different types of diabetes, the different forms of hypertension in the diabetic patient, the modalities of treating hypertension in presence of various specific complications (metabolic syndrome, coronary heart disease or renal impairment), and the specificities when hypertension is associated with diabetic cardiovascular autonomic neuropathy.

Measuring or estimating glomerular filtration rate (GFR) is still considered the best way to apprehend global renal function. In 2009, the Chronic Kidney Disease Epidemiology (CKD-EPI) equation was proposed as a better estimator of GFR than the Modification of Diet in Renal Disease (MDRD) study equation. It is supposed to underestimate GFR to a lesser degree in higher GFR levels. In this article, we present and discuss the performances of this new equation. Based on articles published between 2009 and 2012, we underline its advantages, notably better knowledge of chronic kidney disease prevalence, but also its limitations, especially in some specific populations. Our conclusion is that all equations are estimations and that nephrologists should always remain cautions in their interpretation. [less ▲]

Design and method : Office blood pressure (OBP) and home BP (HBP) were measured in 70 kidney transplant patients (KT) (43 men/27 women;KT>1 year), all were treated with antihypertensive drugs (mean number: 2±1). Mean age: 56±11 years, mean graft survival: 7±6.6 years, mean GFR: 65.6±24 ml/min, diabetes:27% and current smoking:11.5%. HBP (Omron M6) was measured during 7 days following the OBP measurement, mean HBP was calculated from day 2 to day 7. Uncontrolled BP was defined by OBP>=140-90 (>=130-80 when diabetes) and HBP>=135-85 (>=130-80 when diabetes). The day of the OBP measurement and the last day of HBP, patients collected 24h- urine and recorded at the same time their food and beverage consumption. Sodium and potassium were measured in urines and their intakes were quantified through food records. Urinary and diet Na+, K+ did not differ between the two urine collections 7 days apart. Results: 16 patients(23%) had controlled BP (OBP and HBP) while 34 (49%) remained with sustained hypertension (SHT) despite treatment, 14 (20%) had masked uncontrolled hypertension (MHT, OBP<140-90 and HBP>=135-85,130-80 if diabetes for both).When comparing the controlled and SHT, no differences were found with age, graft survival, BMI, GFR, calcineurin inhibitors or number and type of antihypertensive drugs. The groups did not differ by their sodium excretion (154±93 vs 162±88 mmol/24h) but well by their K excretion significantly higher in controlled patients (68±17 vs 53±20 mmol/24h,p=0.018) giving a Na/K ratio higher in SHT (3.2±1.3 vs2.2±1.2,p=0.03). Diet analysis showed significantly higher intakes of K (fruits, vegetables) in controlled patients (3279±753 vs 2208±720 mg/24h,p=0.010) whereas both groups consumed on average 9 g/24h of salt. When controlled for age, BMI and Na excretion, Home systolic BP was inversely and significantly correlated with urinary potassium (- 0.46;P=0.002) while no correlation was found with urinary Na.Conclusions: KT patients remaining hypertensive and well controlled patients had both high salt consumption. However, well controlled patients differed by significant higher potassium intakes and excretion. Urinary Na/K ratio could be a useful tool contributing to an optimal BP control in KT patients. However, impact of increasing potassium intakes on uncontrolled BP in KT has to be validated by prospective randomized studies [less ▲]
