Abstract
Kidney Biopsy (KB) is a crucial diagnostic tool in the field of renal diseases and is routinely performed in nephrology departments. A previous survey conducted by the Société Francophone de Néphrologie Dialyse Transplantation (SFNDT) revealed significant disparities in clinical practices, sometimes conflicting with the existing literature and recently published recommendations. In response, the SFNDT wished to promote the development of best practice guidelines, under the auspices of the French National Authority for Health (HAS), to establish a standardized framework for performing kidney biopsies in France.

Abstract
RATIONALE & OBJECTIVE Fibrinogen A α-chain amyloidosis (AFib amyloidosis) is a form of amyloidosis resulting from mutations in the fibrinogen A α-chain gene (FGA), causing progressive kidney disease leading to kidney failure. Treatment may include kidney transplantation (KT) or liver-kidney transplantation (LKT), but it is not clear what factors should guide this decision. The aim of this study was to characterize the natural history and long-term outcomes of this disease, with and without organ transplantation, among patients with AFib amyloidosis and various FGA variants. STUDY DESIGN Case series. SETTING & PARTICIPANTS 32 patients with AFib amyloidosis diagnosed by genetic testing in France between 1983 and 2014, with a median follow-up of 93 (range, 4-192) months, were included. RESULTS Median age at diagnosis was 51.5 (range, 12-77) years. Clinical presentation consisted of proteinuria (93%), hypertension (83%), and kidney failure (68%). Manifestations of kidney disease appeared on average at age 57 (range, 36-77) years in patients with the E526V variant, at age 45 (range, 12-59) years in those with the R554L variant (P<0.001), and at age 24.5 (range, 12-31) years in those with frameshift variants (P<0.001). KT was performed in 15 patients and LKT was performed in 4. In KT patients with the E526V variant, recurrence of AFib amyloidosis in the kidney graft was less common than with a non-E526V (R554L or frameshift) variant (22% vs 83%; P=0.03) and led to graft loss less frequently (33% vs 100%). Amyloid recurrence was not observed in patients after LKT. LIMITATIONS Analyses were based on clinically available historical data. Small number of patients with non-E526V and frameshift variants. CONCLUSIONS Our study suggests phenotypic variability in the natural history of AFib amyloidosis, depending on the FGA mutation type. KT appears to be a viable option for patients with the most common E526V variant, whereas LKT may be a preferred option for patients with frameshift variants.

Early predictors of one-year mortality in patients over 65 presenting with ANCA-associated renal vasculitis: a retrospective, multicentre study. BMC Nephrol 2018; 19:317.

Abstract
Background The risk of early death is particularly high in patients over the age of 65 presenting with antineutrophil cytoplasmic antibody (ANCA)-associated renal vasculitis. We hypothesized that by combining disease severity markers, a comorbidity index and serious adverse event reports, we would be able to identify early predictors of one-year mortality in this population. Methods We performed a multicentre, retrospective study in the nephrology and internal medicine departments of six tertiary hospitals in northern France. A total of 149 patients (median [interquartile range (IQR)] age: 72.7 [68.5–76.8] years) presenting with ANCA-associated vasculitis and renal involvement were included between January 2002 and June 2015. The primary endpoint was the one-year mortality rate. Results Renal function was severely impaired at presentation (median [IQR] peak serum creatinine (SCr): 337 [211–522] μmol/l), and 45 patients required dialysis. The Five-Factor Score (FFS, scored as + 1 point for each poor prognostic factor (age > 65 years, cardiac symptoms, gastrointestinal involvement, SCr ≥150 μmol/L, and the absence of ear, nose, and throat involvement)) was ≥3 in 120 cases. The one-year mortality rate was 19.5%. Most of the deaths occurred before month 6, and most of these were related to severe infections. In a univariate analysis, age, a high comorbidity index, a performance status of 3 or 4, a lack of co-trimoxazole prophylaxis, early severe infection, and disease activity parameters (such as the albumin level, haemoglobin level, peak SCr level, dialysis status, and high FFS) were significantly associated with one-year mortality. In a multivariable analysis, the best predictors were a high FFS (relative risk (RR) [95% confidence interval (CI)] = 2.57 [1.30–5.09]; p = 0.006) and the occurrence of a severe infection during the first month (RR [95%CI] = 2.74 [1.27–5.92]; p = 0.01). Conclusions When considering various disease severity markers in over-65 patients with ANCA-associated renal vasculitis, we found that an early, severe infection (which occurred in about a quarter of the patients) is a strong predictor of one-year mortality. A reduction in immunosuppression, the early detection of infections, and co-trimoxazole prophylaxis might help to reduce mortality in this population.

Abstract
Chronic kidney disease (CKD) is a frequent and serious complication of atypical haemolytic uremic syndrome (aHUS). We aimed to develop a simple accurate model to predict the risk of renal dysfunction in aHUS based on clinical and biological features available at hospital admission. Renal function at 1-year follow-up, based on an estimated glomerular filtration rate < 60mL/min/1.73m2 as assessed by the Modification of Diet in Renal Disease equation, was used as an indicator of significant CKD. Prospectively collected data from a cohort of 156 aHUS patients who did not receive eculizumab were used to identify predictors of CKD. Covariates associated with renal impairment were identified by multivariate analysis. The model performance was assessed and a scoring system for clinical practice was constructed from the regression coefficient. Multivariate analyses identified three predictors of CKD: a high serum creatinine level, a high mean arterial pressure and a mildly decreased platelet count. The prognostic model had a good discriminative ability (area under the curve = .84). The scoring system ranged from 0 to 5, with corresponding risks of CKD ranging from 18% to 100%. This model accurately predicts development of 1-year CKD in patients with aHUS using clinical and biological features available on admission. After further validation, this model may assist in clinical decision making.

Abstract
Alkali therapy is frequently used during chronic kidney disease and nephrolithiasis: nephrologists and urologists are the key operators. Very few is known about the underlying conditions of such a prescription: the aim of this study was to delineate those determinants. We conducted a prospective survey where French nephrologists and urologists were involved. Responders were without gender distinction and principally nephrologists. Prescription frequency was associated with gender (women), specialty (nephrologists), indications and perceived efficiency. Urologists prescribe more often during nephrolithiasis and nephrologists during chronic kidney disease. Urologists were more expert (by scoring on mineral-based alkaline waters compositions knowledge). By multivariate analysis, prescription frequency is associated with gender (women), indications and perceived efficiency by prescribers, which is itself influenced by feedback from patients. These results could have been influenced by a huge representation of nephrologists but foster physicians to go on listening to feedback from patients, due to a lack of clinical trials on the efficiency of mineral-based alkaline waters in such a field. Finally, physicians' education (especially young nephrologists) on mineral-based alkaline waters should be intensified.

[Hyponatremias: From pathophysiology to treatments. Review for clinicians]. Nephrol Ther 2015; 11:201-12.

Abstract
Hyponatremia could be defined as a public health topic: too many patients are concerned in both hospitalized and general populations; hyponatremia induces lots of clinical outcomes and a great economic burden. Its pathophysiology involves thirst regulation (hypotonic water intakes) and losses regulation (through the kidney under vasopressin control). Diagnostic approach should insure that hyponatremia reflects hypo-osmolality and hypotonicity: first, a false hyponatremia should be ruled out, then a non-hypotonic one. Next step is clinic: extracellular status should be evaluated. When increased, any edematous status should be evoked: heart failure, liver cirrhosis or nephrotic syndrome. When decreased, any cause of extracellular dehydration should be evoked: natriuresis could help distinguishing between renal (adrenal insufficiency, diuretics use or salt-losing nephropathy) or extrarenal (digestive mostly) etiologies. When clinically normal, a secretion of inappropriate antidiuretic hormone (SIADH) should be evoked, once hypothyroidism or hypoadrenocorticism have been ruled out. Therapy depends on the severity of the clinical impact. From extracellular rehydration, through fluid restriction, the paraneoplastic and heart failure-induced SIADH benefit from a new class of drug, available among the therapeutic strategies: aquaretics act through antidiuretic hormone receptor antagonism (vaptans). Their long-term benefits still have to be proven but it is a significant step forward in the treatment of hyponatremias.

Microvascular inflammation and acute tubular necrosis are major histologic features of hantavirus nephropathy. Hum Pathol 2015; 46:827-35. [PMID: 25791582 DOI: 10.1016/j.humpath.2015.02.002] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/04/2014] [Revised: 01/31/2015] [Accepted: 02/04/2015] [Indexed: 10/24/2022]
Abstract
Hantavirus nephropathy (HVN) is an uncommon etiology of acute renal failure due to hantavirus infection. Pathological features suggestive of HVN historically reported are medullary interstitial hemorrhages in a background of acute interstitial nephritis (AIN). However, interstitial hemorrhages may be lacking because of medullary sampling error. This emphasizes that other pathological criteria may be of interest. We performed a retrospective clinicopathological study of 17 serologically proven HVN cases with renal biopsy from 2 nephrology centers in northern France. Histologic analysis was completed by immunohistochemistry with anti-CD3, anti-CD68, and anti-CD34 antibodies. Three control groups were not related to hantavirus infection: acute tubular necrosis (ATN) of ischemic or toxic etiology and AIN were used for comparison. Renal biopsy analysis showed that almost all HVN cases with medullary sampling (9/10) displayed interstitial hemorrhages, whereas focal hemorrhages were detected in 2 of the 7 "cortex-only" specimens. ATN was common, as it was present in 15 (88.2%) of 17 HVN cases. By contrast, interstitial inflammation was scarce with no inflammation or only slight inflammation, representing 15 (88.2%) of 17 cases. Moreover, HVN showed inflammation of renal microvessels with cortical peritubular capillaritis and medullary vasa recta inflammation; peritubular capillaritis was significantly higher in HVN after comparison with ischemic and toxic ATN controls (P = .0001 and P = .003, respectively), but not with AIN controls. Immunohistochemical studies highlighted the involvement of T cells and macrophages in renal microvascular inflammation related to HVN. Our study showed that microvascular inflammation, especially cortical peritubular capillaritis, and ATN are important histologic features of HVN.

Abstract
BACKGROUND Although several risk factors associated with complications after renal biopsy (RB) have been identified, recommendations for RB procedures are still lacking. Our working group, appointed by the scientific commission of the Société de néphrologie in France, aimed to depict the main aspects of the practice of RB in adults in France, before establishing some guidelines. METHODS Members of the Société de néphrologie in France were asked to participate to a questionnaire survey on RB procedures. RESULTS Eighty-eight nephrologists from 74 units (27 in teaching hospitals, 35 in public general hospitals, and 12 in private centers) participated in our study. Native kidney and graft biopsies were performed in 73 and 35 units, respectively. RB activity was highly variable among units, ranging from several hundred to less than ten per year. Transjugular RB was judged to be smoothly accessible in 28 out of 73 units (38.4%). Significant variations in practices were observed regarding patient information before RB, assessment of hemorrhagic risk factors, care of patients with antiplatelet agents and hemorrhagic risk factors, and radiological guidance. Early discharge (<12 hours) was the rule in three (4.1%) units for native kidney biopsies and in ten (28.6%) units for graft biopsies. CONCLUSIONS Our study is the first to provide a representative picture of "everyday" RB practices in a country. Consensual recommendations on all points mentioned are provided here.

Abstract
Renal disease in ANCA-associated vasculitis (AAV) is characterized by a pauci-immune necrotizing glomerulonephritis. Renal biopsy is essential for diagnosis, treatment strategy and also for the long-term prognosis of AAV. The prospective randomized trials conducted by the EUVAS and GFEV have contributed to define therapeutic guidelines. The current standard of care can be divided into two phases: initial immunosuppression for rapid and effective onset of remission and subsequent maintenance therapy to prevent relapses. Despite these recent therapeutic advances, mortality and morbidity, such as end-stage renal failure, remain high, related to diagnosis delay, drug-related toxicity, refractory disease and propensity of AAV to relapse. Conventional therapies need to be optimized, especially in high-risk patients. Targeting B-cells with rituximab is a new and attractive therapeutic option, but long term benefits and safety are still unknown.

Abstract
BACKGROUND Although several risk factors associated with complications after renal biopsy (RB) have been identified, the gold standard for RB procedures remains to be defined. Practices vary widely among nephrologists, depending on personal experience and the availability of particular techniques.

Abstract
Lanthanum carbonate is a new nonaluminium, noncalcium phosphate binder. The drug is well-tolerated its side-effects seem comparable to those of other phosphate binders. The most frequent side-effects are gastrointestinal complications. Cerny [New England Journal of Medecine 355(2006)1160.] and Kunzendorf have recently reported another effect of lanthanum carbonate based on its radiographic characteristics. We report another case of opacification of the intestine with lanthanum carbonate which underlines some difficulties in the use of this new phosphate binder.
