Only limited data is available on the management of the chronic kidney disease-associated bone and mineral metabolism disorder (CKD-MBD) in the pre-dialysis stages of CKD in France. A better knowledge of current management habits could lead to an improvement in the implementation of international recommendations (KDIGO). The 3rd version of the French Phosphorus and Calcium Survey Photo-Graphe (Sanofi) included a cohort of CKD stages 4 and 5 patients, whose aim was to examine the prevalence of CKD-MBD and the quality of its management in patients under the care of 62 nephrologists from over 20 geographical regions in France...

Thrombotic microangiopathy (TMA) is a group of disorders characterized by mechanical hemolytic anemia with thrombocytopenia and an ischemic organic lesion of variable and potentially fatal importance affecting mostly the kidneys and the brain with histologically a disseminated and occlusive microvasculopathy. The incidence of TMA represents 15% of acute kidney failure in oncological setting, largely due to the introduction of anti-angiogenic agents over the past decade. It may be more rarely related to cancer itself...

Emphysematous pyelonephritis is a necrotizing infection of the renal parenchyma and peri-renal tissues, characterized by the presence of air within the parenchyma of the urinary tract and peri-renal space. This is a severe complication, which involves the functional prognosis of the kidney and the patient's prognosis. The emphysematous pyelonephritis is a rare complication of renal transplantation. Its gravity is linked particularly to the fragility of immunosuppressed patients. The authors report the case of an emphysematous pyelonephritis having occurred 9 months after transplantation in a patient 58 years...

The gradual loss of weight and function of muscle in patients with chronic kidney disease as in the elderly impacts the quality of life. Early management should help slow the functional limitation. Physical activity is the first therapy to propose that ensures stability of muscle mass and improved function. Resistance training programs have proven effective but are not yet widely available in nephrology units. The nutritional management should not be forgotten because there is a resistance to anabolism and protein intake should be involved in physical activity program...

Munchausen syndrome by proxy is a persistent fabrication of illness done by a person to another. Renal and urologic forms of this syndrome are not as uncommon as can be thought; a review of all the cases of Munchausen-by-proxy syndrome reveals that 25% of the children had renal or urologic issues. This syndrome can result in a serious diagnostic dilemma for the physicians; knowing this entity can allow early recognition of falsification and limit the physical and psychological damages caused in the victim. In this study, we reviewed the pediatric nephrology cases of Munchausen syndrome by proxy, grouping them through the principal signs of presentation...

Autosomal dominant polycystic kidney disease (ADPKD) is an inherited disease that usually occurs in adulthood. The majority of affected patients will develop renal complications related to cysts during their life, but may sometimes also develop severe extrarenal complications. The aim of this study is to review quantitative and qualitative results of researches that have investigated quality of life of patients suffering ADPKD. The results obtained with health-relative quality of life scales are contradictory and lack of sensibility according to the special features of ADPKD, for psychological impact for instance...

Encapsulating peritoneal sclerosis is a rare but devastating complication of long-term peritoneal dialysis with a high mortality rate. The incidence is between 0.5 and 2.5%, decreasing with time. PSE is defined as a clinical syndrome with signs of gastrointestinal obstruction, inflammation parameters, radiological and macroscopic changes. The duration of treatment and the cessation of peritoneal dialysis are the main risks. About 75% occured in patients on hemodialysis or after kidney transplantation. Morphological alterations are disappearance of mesothelial layer, submesothelial fibrosis, interstitial sclerosis and vasculopathy...

BACKGROUND: Escherichia coli strains causing Urinary Tract Infections (UTI) have a fecal origin. METHODS: A fecal sample was collected before Kidney Transplantation (KT) and concomitantly with urine at each of the 15 E. coli UTIs which occurred in 11 KT recipients. Unique E. coli strains were identified among 25 isolates per feces and 5 isolates per urinary sample by random amplification of polymorphic DNA. Phylogenetic group (which is correlated to virulence in the E...

Thrombotic microangiopathy is a rare but severe complication of treatment with gemcitabine. Its prevalence increases because gemcitabine's indications are growing. We report four cases, which presented with common clinical and biological manifestations, i.e. high blood pressure, proteinuria and increasing plasmatic creatinine level. However, severity was not similar, hemodialysis was inconstant. There is no consensus on treatment for this condition. Stopping gemcitabine is essential. Treatment was dispensed considering the severity of the presentation: plasma exchange therapy of variable outcome, and eculizumab, which was efficient when used...

Partial nephrectomy is the gold standard for the renal tumours less than 7 to 10cm whenever feasible in order to preserve renal function. The extension of nephron-sparing surgery using a mini-invasive approach is possible by robotic surgery. Radical nephrectomy is mandatory in the other situations and especially in case of locally advanced renal carcinoma. The place of cytoreductive nephrectomy in metastatic renal cell carcinoma is the purpose of the CARMENA trial. Tyrosine kinase inhibitors are currently the first line treatment; but in the near future new immunotherapy by checkpoints molecules could crucially change the treatment of metastatic renal cell carcinoma...

Purification of high molecular uremic toxins by conventional hemodialysis is limited. It remains associated with a high morbidity and excessively high mortality. Online hemodiafiltration using a high permeability hemodiafilter, an ultrapure dialysate, and which tends to maximize substitution volumes, provides a high efficiency and low bio-incompatibility renal supplementation. Regular use of online hemodiafiltration is associated with reduced morbidity (reduction of intradialytic hypotension episodes, improved blood pressure control, reduced inflammatory profile, better anemia correction and prevention of β2-microglobulin-associated amyloidosis)...

We present the case of a family whose members have high levels of serum calcium (hypercalcaemia) by loss of function of the enzyme vitamin D 24-hydroxylase due to bi-allelic mutations in the CYP24A1 gene: c.443 T>C (p.Leu148Pro) and c.1187 G>A (p.Arg396Gln). 24-VITD hydroxylase is a key player in regulating the circulating calcitriol, its tissue concentration and its biological effects. Transmission is recessive. The estimated prevalence of stones in the affected subjects is estimated between 10 and 15%...

A 21-year-old man ingested 75g of pure caffeine, in an attempt to commit suicide. This represents 7.5 times the minimal lethal dose. Caffeine, 1,3,7-trimethylxanthine, is the most widely consumed psychoactive compound worldwide. It is mostly found in coffee, tea, energizing drinks and in some drugs. However, it has become really easy to obtain pure caffeine (powder or tablets) on the Internet. Mechanisms of action are dose-dependent. When caffeine overdosing occurs, neurologic, cardiovascular and renal systems are mainly affected...

BACKGROUND AND AIM: Primary hyperoxalurias are rare inborn errors of metabolism resulting in increased endogenous production of oxalate that leads to excessive urinary oxalate excretion. Diagnosis of primary hyperoxaluria type 1 (PH1) is a challenging issue and depends on diverse diagnostic tools including biochemical analysis of urine, stone analysis, renal biopsy, genetic studies and in some cases liver biopsy for enzyme assay. We characterized the clinical presentation as well as renal and extrarenal phenotypes in PH1 patients...

INTRODUCTION: Over the last few decades, the prevalence of obesity has increased dramatically. This increase has been mirrored by a rise in the risk of a number of health conditions, including hypertension, diabetes and chronic kidney disease. Although the weight loss following bariatric surgery has been shown to relieve the severity of diabetes and reduce hypertension, the effect on renal function has been less extensively evaluated. OBJECTIVE: The aims of the present study were to: (i) compare the estimated glomerular filtration rate (eGFR, using the MDRD and CKD-EPI equations) and the calculated glomerular filtration rate (using the 24-hour urine volume) with the measured glomerular filtration rate (mGFR) assessed with the plasma iohexol clearance method in severely obese patients, and (ii) evaluate the effect of weight loss on the mGFR 6 months after bariatric surgery...

The goal this study was to understand the preoccupations of e-patients with Autosomal Dominant Polycystic Kidney Disease (ADPKD), through their discussions on social networks, and to compare them with those of members of a specialized association. We collected and analyzed all messages containing an unequivocal expression of the pathology (polycystic kidney disease, PKD, ADPKD, etc.) available on public forums on the French Internet and all french-language messages posted on the forum of the patient group Association Polykystose-France (PKD-France) during 2 years...
