Abstract
Background The impact of arteriovenous fistula (AVF) or graft (AVG) thrombosis on mortality has been sparsely studied. This study investigated the association between AVF/AVG thrombosis and all-cause and cardiovascular mortality. Methods The data from 2439 patients with AVF or AVG undergoing maintenance haemodialysis (HD) included in the A Study to Evaluate the Use of Rosuvastatin in Subjects on Regular Hemodialysis: An Assessment of Survival and Cardiovascular Events trial (AURORA) were analysed using a time-dependent Cox model. The incidence of vascular access (VA) thrombosis was a pre-specified secondary outcome. Results During follow-up, 278 AVF and 94 AVG thromboses were documented. VA was restored at 22 ± 64 days after thrombosis (27 patients had no restoration with subsequent permanent central catheter). In multivariable survival analysis adjusted for potential confounders, the occurrence of AVF/AVG thrombosis was associated with increased early and late all-cause mortality, with a more pronounced association with early all-cause mortality {hazard ratio [HR] < 90 days 2.70 [95% confidence interval (CI) 1.83–3.97], P < 0.001; HR > 90 days 1.47 [1.20–1.80], P < 0.001}. In addition, the occurrence of AVF thrombosis was significantly associated with higher all-cause mortality, whether VA was restored within 7 days [HR 1.34 (95% CI 1.02–1.75), P = 0.036] or later than 7 days [HR 1.81 (95% CI 1.29–2.53), P = 0.001]. Conclusions AVF/AVG thrombosis should be considered as a major clinical event since it is strongly associated with increased mortality in patients on maintenance HD, especially in the first 90 days after the event and when access restoration occurs >7 days after thrombosis. Clinicians should pay particular attention to the timing of VA restoration and the management of these patients during this high-risk period. The potential benefit of targeting overall patient risk with more aggressive treatment after AVF/AVG restoration should be further explored.

Abstract
This national, prospective and multicenter study aimed to describe the real-life impact of comorbidities on hemoglobin stability in patients with chronic kidney disease on hemodialysis, treated with CERA in relay of an erythropoietin stimulating agent. Comorbidities were defined by the Charlson Index (adjusted on age) and hemoglobin stability as a variation of ±1g/dL after the 6-month treatment period. The 585 analyzed patients were distributed as follows according to the adjusted Charlson index: score≤3 (12% of patients), 4≤score≤5 (17%), 6≤score≤7 (31%) and score≥8 (40%). At CERA start, its median monthly dose was of 100μg for the overall population, with no changes during the treatment period and with little variation according to the comorbidity score. Patients with stable hemoglobin (56%, 67% if score≤3) were more numerous to reach the therapeutic target range between 10 and 12g/dL after 6 months (85% versus 43% if not stable hemoglobin). Patients with low C-reactive protein value (≤5mg/L ; P=0.04), no red blood cell transfusion (P=0.03), or no/low dose of intravenous iron (≤200mg ; P=0.03) were more likely to reach stable hemoglobin under CERA after 6 months. Among the 644 CERA-treated patients, 4 patients (<1%) had one serious adverse event related to treatment. A stable hemoglobin within the therapeutic target was reached in the majority of the patients after 6 months in current practice with a lower CERA dose, regardless of the comorbidities scores of patients on hemodialysis.

Abstract
BACKGROUND Assessment of human leukocyte antigen (HLA) matching by using high-resolution allele typing and knowledge of HLA molecule structure may lead to better prediction of de novo donor-specific antibody (dnDSA) development. METHODS We conducted a single-center cohort study among 150 non-sensitized first kidney transplant recipients to compare the association between antigenic (Ag), allelic (Al), eplet (Ep), amino acid (AAMS) HLA matching and electrostatic (EMS) and hydrophobic (HMS) mismatch scores, and the development of dnDSA. RESULTS After a mean follow-up time of 49.3 ± 17.7 months, 18 patients (12%) developed dnDSA. The number of HLA mismatches (MM) was significantly associated with the development of dnDSA. The optimal threshold, determined by Harrell's C-index, varied according to the method (5 MM for Ag, P = 0.006; 6 for Al, P = 0.009; 22 for Ep, P = 0.005; 42 for AAMS, P = 0.0007; 45 for EMS, P = 0.009 and 44 for HMS, P = 0.026). C-indices were similar for all matching approaches, suggesting a similar prediction of dnDSA development. CONCLUSION In this cohort of low immunological risk transplant patients, the use of Al or Ep matching did not improve the prediction of dnDSA development in comparison with the traditional approach.

Abstract
Abstract
Background
Informing kidney transplant recipients of their prognosis and disease progression is of primary importance in a patient-centred vision of care. By participating in decisions from the outset, transplant recipients may be more adherent to complex medical regimens due to their enhanced understanding.
Methods
We proposed to include repeated measurements of serum creatinine (SCr), in addition to baseline characteristics, in order to obtain dynamic predictions of the graft failure risk that could be updated continuously during patient follow-up. Adult recipients from the French Données Informatisées et VAlidées en Transplantation (DIVAT) cohort transplanted for the first or second time from a heart-beating or living donor and alive with a functioning graft at 1 year post-transplantation were included.
Results
The model was composed of six baseline parameters, in addition to the SCr evolution. We validated the dynamic predictions by evaluating both discrimination and calibration accuracy. The area under the receiver operating characteristic curve varied from 0.72 to 0.76 for prediction times at 1 and 6 years post-transplantation, respectively, while calibration plots showed correct accuracy. We also provided an online application tool (https://shiny.idbc.fr/DynPG).
Conclusion
We have created a tool that, for the first time in kidney transplantation, predicts graft failure risk both at an individual patient level and dynamically. We believe that this tool would encourage willing patients into participative medicine.

Abstract
AIMS Drug prescription is difficult to manage in patients with chronic kidney disease (CKD). We assessed the prevalence and determinants of inappropriate drug prescriptions (whether contraindications or inappropriately high doses) with regard to kidney function in patients with CKD under nephrology care. We also assessed the impact of the equation used to estimate GFR on the prevalence estimates. METHODS The CKD-REIN cohort includes 3033 outpatients with CKD (eGFR between 15 and 60 ml min-1 1.73 m-2 ). We examined the daily doses of pharmacological agents prescribed at study entry. Inappropriate prescription was defined as the reported prescription of either a contraindicated drug or an indicated drug at an inappropriately high dose level with regard to the patient's GFR, as estimated with the CKD-EPI equation, the de-indexed CKD-EPI equation, or the Cockcroft-Gault (CG) equation. Multivariate logistic regression was used to assess the determinants of inappropriate prescription risk. RESULTS At baseline, patients' median [interquartile range] number of drugs prescribed per patient was 8 [5-10]. Half of the patients had been prescribed at least one inappropriate drug. Anti-gout, cardiovascular agents and antidiabetic agents accounted for most of the inappropriate prescriptions. The percentage of inappropriate prescriptions varied from one GFR equation to another: 52% when using the CKD-EPI equation, 47% when using the de-indexed CKD-EPI equation and 41% with the CG equation. A multiple logistic regression analysis showed significantly higher odds ratios [95% confidence interval] for inappropriate prescriptions in male patients (1.28 [1.07; 1.53]), patients with diabetes (1.34 [1.06; 1.70]), those with a high BMI (1.58 [1.25; 1.99]), and those with a low GFR (10.2 [6.02; 17.3]). The risk of having at least one inappropriate prescription increased with the number of drugs per patient (P for trend < 0.0001) and therefore the odds ratio was 5.88 [4.17; 8.28] for those who received at least 11 prescribed medications compared to those who received fewer than 5. CONCLUSION Our results emphasize the complexity of drug management for CKD patients, for whom inappropriate prescription appears to be common.

Abstract
BACKGROUND Despite advances in immunosuppressive therapy, kidney graft survival has failed to improve during the last decades. Ischemia/reperfusion injury (IRI) is one of the main pathophysiological mechanisms underlying delayed graft function, which is associated with poor long-term graft survival. Due to organ shortage, the proportion of grafts from expanded criteria donors (ECDs) is ever growing. These grafts may particularly benefit from IRI prevention. In preclinical models, mineralocorticoid receptor antagonists (MRAs) have been shown to efficiently prevent IRI. This study aims to assess the effect of MRA administration in the early phase of kidney transplantation (KT) among recipients of ECD grafts on mid-term graft function. METHODS/DESIGN This is a multicenter, double-blind, placebo-controlled, randomized clinical trial. Patients on hemodialysis and undergoing a single or a dual KT from an ECD will be eligible for inclusion. We plan to randomize 132 patients. Included patients will be randomized (1:1) to receive either eplerenone 25 mg every 12 h during 4 days (the first dose being administered just prior to KT) or placebo. The primary outcome is graft function at 3 months, assessed by glomerular filtration rate (GFR, in mL/min/1.73m2) measured using iohexol clearance. Secondary outcomes include (1) proportion of patients with either dialysis dependency or a GFR < 30 mL/min/1.73m2 at 3 months, (2) proportion of patients with immediate, slow, or delayed graft function, (3) proteinuria at 3 months, (4) occurrence of hyperkalemia during the first week following KT, (5) length of hospital stay for the KT, and (6) occurrence of biopsy-proven acute rejection in the first 3 months following KT. Estimated GFR, graft, and patient survival will also be collected at 1, 3, and 10 years via the national database of organ recipients. DISCUSSION Improvement of ECD grafts is a public health priority, since better ECD outcomes could eventually limit organ shortage. MRA administration in the early phase of KT may prevent IRI and subsequently improve mid-term graft function. The trial will also assess the safety of MRA administration in this population, primarily the absence of threatening hyperkalemia. TRIAL REGISTRATION ClinicalTrials.gov, NCT02490904 .

Abstract
Background In low-immunological risk kidney transplant recipients (KTRs), reduced exposure to calcineurin inhibitor (CNI) appears particularly attractive for avoiding adverse events, but may increase the risk of developing de novo Donor Specific Antibodies (dnDSA). Methods CNI exposure was retrospectively analyzed in 247 non-HLA immunized first KTRs by taking into account trough levels (C0) collected during follow-up. Reduced exposure to CNI was defined as follows: C0 less than the lower limit of the international targets for ≥50% of follow-up. Results During a mean follow-up of 5.0 ± 2.0 years, 39 patients (15.8%) developed dnDSA (MFI ≥1000). Patients with DSA were significantly younger (46.6 ± 13.8 vs. 51.7 ± 14.0 years, p = 0.039), received more frequently poorly-matched grafts (59% with 6–8 A-B-DR-DQ HLA mismatches vs. 34.6%, p = 0.016) and had more frequently a reduced exposure to CNI (92.3% vs. 62.0%, p = 0.0002). Reduced exposure to CNI was associated with an increased risk of dnDSA (multivariable HR = 9.77, p = 0.002). Reduced exposure to CNI had no effect on patient survival, graft loss from any cause including death, or post-transplant cancer. Conclusions Even in a low-immunological risk population, reduced exposure to CNI is associated with increased risk of dnDSA. Benefits and risks of under-immunosuppression must be carefully evaluated before deciding on CNI minimization.

Abstract
Abstract
Background
Although chronic kidney disease (CKD) and age are major risk factors for cardiovascular disease (CVD), little is known about the relative proportions of atheromatous and non-atheromatous CVD by age in CKD patients.
Methods
We used baseline data from the French Chronic Kidney Disease-Renal Epidemiology and Information Network (CKD-REIN) cohort of 3033 patients (65% men) with CKD Stages 3–4 to study crude and adjusted associations between age, the estimated glomerular filtration rate (eGFR), atheromatous CVD (coronary artery disease, peripheral artery disease and stroke) and non-atheromatous CVD (heart failure, cardiac arrhythmia and valvular heart disease).
Results
Mean age was 66.8 and mean Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) eGFR was 32.9 mL/min/1.73 m2. In the <65, (65–74), (75–84) and ≥85 year age groups, the prevalence was, respectively, 18.7, 35.5, 42.9 and 37.8% for atheromatous CVD, and 14.9, 28.4, 38.1 and 56.4% for non-atheromatous CVD. After adjusting for albuminuria, sex and CVD risk factors, the odds ratio (OR) [95% confidence interval (CI)] for (65–74), (75–84) and ≥85 age groups (compared with the <65 group) was, respectively, 1.99 (1.61–2.46), 2.89 (2.30–3.62), 2.72 (1.77–4.18) for atheromatous CVD and 2.07 (1.66–2.58), 3.15 (2.50–3.97), 7.04 (4.67–10.61) for non-atheromatous CVD. Compared with patients with an eGFR ≥30 mL/min/1.73 m2, those with an eGFR <30 mL/min/1.73 m2 had a higher OR for atheromatous CVD [1.21 (1.01–1.44)] and non-atheromatous CVD [1.16 (0.97–1.38)].
Conclusions
In this large cohort of CKD patients, both atheromatous and non-atheromatous CVD were highly prevalent and more frequent in older patients. In a given age group, the prevalence of atheromatous and non-atheromatous CVD was similar (except for a greater prevalence of non-atheromatous CVD after 85).

Abstract
Background Observational studies have reported increased mortality rates in hyperkalaemic or hypokalaemic chronic haemodialysis patients. This study assessed the prevalence and recurrence of hyperkalaemia (HK) along with the concomitant prescription of low-potassium (K) dialysis baths and of K-binding agents in a registry within a French regional disease management programme. Methods This was a prospective multicentre (14 chronic haemodialysis centres, Lorraine Region) study encompassing 527 chronic haemodialysis patients followed from 2 January 2014 to 31 December 2015. Predialysis serum K (14 734) measurements, dialysis bath K concentrations and concomitant K binder prescriptions were collected with an electronic health record system. Results At baseline, 26.4%, 13.8% and 4.9% of patients were hyperkalaemic (i.e. K >5.1, 5.5 or 6 mmol/L, respectively) and 12.5%, 1.9% and 0.4% were hypokalaemic (i.e. K<4, 3.5 or 3 mmol/L, respectively). A total of 61% of patients were prescribed a K-binding resin [essentially sodium polystyrene sulfonate (SPS)], while 2 mmol/L and 3 mmol/L K concentration baths were used relatively equally. Over time, the proportion of patients being prescribed any K-binding agent increased up to 78%. The percentage of patients experiencing HK at any time was 73.8% (HK >5.1 mmol/L), 57.9% (HK >5.5 mmol/L) and 34.5% (HK >6 mmol/L). Only 6.3% of patients became normokalaemic within 3 months after an HK >5.5 mmol/L despite dynamic management of K baths and K binders (i.e. increased prescription of 2 mmol/L K baths and increased SPS doses). Conclusions HK was found to be highly prevalent and recurrent in this regional registry despite the widespread and dynamic prescription of low-K dialysis baths and K binders. More effective potassium mitigating strategies are eagerly warranted.

[PMID: 29706470 DOI: 10.1016/j.diabet.2018.03.007] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/24/2017] [Revised: 02/27/2018] [Accepted: 03/27/2018] [Indexed: 12/15/2022]
Abstract
AIM To describe current practices of glucose-lowering treatments in people with diabetes and chronic kidney disease (CKD), the associated glucose control and hypoglycaemic symptoms, with an emphasis on sex differences. METHODS Among the 3033 patients with CKD stages 3-5 recruited into the French CKD-REIN study, 645 men and 288 women had type 2 diabetes and were treated by glucose-lowering drugs. RESULTS Overall, 31% were treated only with insulin, 28% with combinations of insulin and another drug, 42% with non-insulin glucose-lowering drugs. In CKD stage 3, 40% of patients used metformin, 12% at stages 4&5, similar for men and women; in CKD stage 3, 53% used insulin, similar for men and women, but at stages 4&5, 59% of men and 77% of women used insulin. Patients were reasonably well controlled, with a median HbA1c of 7.1% (54mmol/mol) in men, 7.4% (57mmol/mol) in women (P=0.0003). Hypoglycaemic symptoms were reported by 40% of men and 59% of women; they were not associated with the estimated glomerular filtration rate, nor with albuminuria or with HbA1c in multivariable analyses, but they were more frequent in people treated with insulin, particularly with fast-acting and pre-mixed insulins. CONCLUSION Glucose-lowering treatment, HbA1c and hypoglycaemic symptoms were sex dependent. Metformin use was similar in men and women, but unexpectedly low in CKD stage 3; its use could be encouraged rather than resorting to insulin. Hypoglycaemic symptoms were frequent and need to be more closely monitored, with appropriate patient-education, especially in women.

Abstract
AIM B-lines count measured with lung ultrasound (LUS) quantifies extravascular lung water and is validated in the setting of acute cardiac failure or chronic dialysis. Patients are often kept in moderately overhydrated states during the early postoperative period following kidney transplantation (KT). We described congestion changes during the early postoperative period following KT and the feasibility of LUS in this setting. METHODS LUS (28 scanning-points method) and inferior vena cava (IVC) measurements were routinely performed in 36 patients after KT. Estimated plasma volume (ePV) was calculated from hemoglobin and hematocrit levels. RESULTS No patient had >15 B-lines during the hospital stay. B-lines slightly increased until Day 4 after KT (Day 1, 1.7 ± 1.7; Day 4, 2.5 ± 2.5) and decreased up to Day 10 (1.4 ± 2.2; P vs Day 4 <.05). More B-lines were observed in patients aged older than 60 (P = .01 at Day 4) whereas IVC diameter and ePV were similar. In patients older than 60, B-lines had weak correlation with body weight variation (r = 0.64; P < .05), IVC diameters (r = 0.59 at Day 4 and r = 0.58 at Day 10; P < .05) but a strong correlation with ePV (r = 0.93 at Day 14; P < .05). B-line changes from Day 1 to Day 10 correlated with IVC diameter changes (r = 0.62; P < .05). CONCLUSION LUS identifies subtle congestion changes during the early postoperative period following KT. The hyperhydration strategy usually followed during this period does not result in overt pulmonary congestion as assessed by LUS, even in older recipients.

Preemptive second kidney transplantation is associated with better graft survival compared with non-preemptive second transplantation: a multicenter French 2000-2014 cohort study. Transpl Int 2017; 31:408-423. [PMID: 29210106 DOI: 10.1111/tri.13105] [Citation(s) in RCA: 21] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2017] [Revised: 08/07/2017] [Accepted: 11/28/2017] [Indexed: 11/30/2022]
Abstract
The impact of preemptive second kidney transplantation (2KT) on graft and patient survival is poorly established. The association between preemptive 2KT (p2KT, N = 93) and outcomes was estimated in a multicenter French cohort of 2KT (N = 1314) recipients using propensity score methods. During the follow-up, there were 274 returns to dialysis and 134 deaths. p2KT was associated with lower death-censored graft loss (HR = 0.39 [0.18-0.88], P = 0.024) and graft failure from any cause including death (HR = 0.42 [0.22-0.80], P = 0.008). Similar associations were observed for death with a functioning graft, although not reaching statistical significance (HR = 0.47 [0.17-1.26], P = 0.13). There was a significant interaction between donor type and p2KT (P for interaction = 0.016). Indeed, p2KT was not significantly associated with the risk of graft failure from any cause including death in living donor 2KT (P = 0.39), whereas the association was substantial in the deceased donor subset (HR = 0.30 [0.14-0.64], P = 0.002). Of note, the adjusted graft survival of p2KT with deceased donor paralleled that of 2KT with living donor, either preemptive or not (93.8% vs. 88.6% at 4 years and 76.1% vs. 70.5% at 8 years, P = 0.13). This large French multicenter study analyzed using propensity scores suggests that p2KT is associated with better graft prognosis.

Abstract
Supplemental Digital Content is available in the text. Short telomere length (TL) in leukocytes is associated with atherosclerotic cardiovascular disease (ASCVD). It is unknown whether this relationship stems from having inherently short leukocyte TL (LTL) at birth or a faster LTL attrition thereafter. LTL represents TL in the highly proliferative hematopoietic system, whereas TL in skeletal muscle represents a minimally replicative tissue.

Abstract
BACKGROUND AND OBJECTIVES Epidemiologic studies suggest that higher serum phosphaturic hormone fibroblast growth factor 23 levels are associated with increase morbidity and mortality. The aim of the FGF23 Reduction Efficacy of a New Phosphate Binder in CKD Trial was to evaluate the effect of sevelamer carbonate on serum C-terminal fibroblast growth factor 23 levels in normophosphatemic patients with CKD stage 3b/4. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Patients with CKD, eGFR between 45 and 15 ml/min per 1.73 m2, fasting serum phosphate concentration >3.1 mg/dl, and serum C-terminal fibroblast growth factor 23 >80 relative units/ml were included in our double-blind, placebo-controlled, randomized multicenter study. All patients received 100,000 IU cholecalciferol at time of randomization. Participants received either placebo or sevelamer carbonate 4.8 g daily during a 12-week period. Biologic parameters, including serum C-terminal fibroblast growth factor 23, intact fibroblast growth factor 23, and α-klotho, were evaluated at baseline and 12 weeks after inclusion. RESULTS Of 96 screened patients, 78 (mean±SD age: 63±13 years old; 70% men; mean eGFR: 27±9 ml/min per 1.73 m2) met the inclusion criteria. At baseline, mean eGFR was 27±9 ml/min per 1.73 m2, mean serum phosphate level was 3.8±0.5 mg/dl, and median (interquartile range) serum C-terminal fibroblast growth factor 23 level was 157 (120-241) relative units/ml. After 12 weeks of treatment, urinary phosphate-to-creatinine ratio fell significantly in the sevelamer group. The sevelamer and placebo groups did not differ significantly in terms of median change in serum C-terminal fibroblast growth factor 23 levels: the median (interquartile range) change was 38 (-13-114) relative units/ml in the placebo group and 37 (-1-101) relative units/ml in the sevelamer group (P=0.77). There was no significant difference in serum intact fibroblast growth factor 23, α-klotho, or phosphate levels changes between the two groups. Serum total and LDL cholesterol levels fell significantly in the sevelamer group. CONCLUSIONS In our double-blind, placebo-controlled, randomized study performed in normophosphatemic patients with CKD, a 12-week course of sevelamer carbonate significantly reduced phosphaturia without changing serum phosphorus but did not significantly modify serum C-terminal fibroblast growth factor 23 and intact fibroblast growth factor 23 or α-klotho levels.

Abstract
BACKGROUND AND OBJECTIVES Post-transplant lymphoproliferative disorders arising after kidney transplantation portend an increased risk of morbidity and mortality. Retransplantation of patients who had developed post-transplant lymphoproliferative disorder remains questionable owing to the potential risks of recurrence when immunosuppression is reintroduced. Here, we investigated the feasibility of kidney retransplantation after the development of post-transplant lymphoproliferative disorder. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS We reviewed the data from all patients who underwent kidney retransplantation after post-transplant lymphoproliferative disorder in all adult kidney transplantation centers in France between 1998 and 2015. RESULTS We identified a total of 52 patients with kidney transplants who underwent 55 retransplantations after post-transplant lymphoproliferative disorder. The delay from post-transplant lymphoproliferative disorder to retransplantation was 100±44 months (28-224); 98% of patients were Epstein-Barr virus seropositive at the time of retransplantation. Induction therapy for retransplantation was used in 48 patients (i.e., 17 [31%] patients received thymoglobulin, and 31 [57%] patients received IL-2 receptor antagonists). Six patients were also treated with rituximab, and 53% of the patients received an antiviral drug. The association of calcineurin inhibitors, mycophenolate mofetil, and steroids was the most common maintenance immunosuppression regimen. Nine patients were switched from a calcineurin inhibitor to a mammalian target of rapamycin inhibitor. One patient developed post-transplant lymphoproliferative disorder recurrence at 24 months after retransplantation, whereas post-transplant lymphoproliferative disorder did not recur in 51 patients. CONCLUSIONS The recurrence of post-transplant lymphoproliferative disorder among patients who underwent retransplantation in France is a rare event.
