Abstract
BACKGROUND AND OBJECTIVES Little is known about the burden of adverse drug reactions in CKD. We estimated the incidence of overall and serious adverse drug reactions and assessed the probability of causation, preventability, and factors associated with adverse drug reactions in patients seen by nephrologists. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS The Chronic Kidney Disease-Renal Epidemiology and Information Network cohort included 3033 outpatients (65% men) with CKD and eGFR<60 ml/min per 1.73 m2, with follow-up for 2 years. Adverse drug reactions were identified from hospitalization reports, medical records, and participant interviews and finally assessed for causality, preventability, and immediate therapeutic management by experts in pharmacology. RESULTS Median (interquartile range) age was 69 (60-76) years old; 55% had eGFR≥30 ml/min per 1.73 m2, and 45% had eGFR<30 ml/min per 1.73 m2. Participants were prescribed a median (range) of eight (five to ten) drugs. Over 2 years, 536 patients had 751 adverse drug reactions, 150 (in 125 participants) classified as serious, for rates of 14.4 (95% confidence interval, 12.6 to 16.5) and 2.7 (95% confidence interval, 1.7 to 4.3) per 100 person-years, respectively. Among the serious adverse drug reactions, 32% were considered preventable or potentially preventable; 16 caused death, directly or indirectly. Renin-angiotensin system inhibitors (15%), antithrombotic agents (14%), and diuretics (10%) were the drugs to which the most adverse drug reactions were imputed, but antithrombotic agents caused 34% of serious adverse drug reactions. The drug was discontinued in 71% of cases, at least temporarily. Adjusted hazard ratios for serious adverse drug reaction were significantly higher in patients with eGFR<30 versus ≥30 ml/min per 1.73 m2 (1.8; 95% confidence interval, 1.3 to 2.6), in those prescribed more than ten versus less than five medications (2.4; 95% confidence interval, 1.1 to 5.2), or in those with poor versus good adherence (1.6; 95% confidence interval, 1.4 to 2.4). CONCLUSIONS Adverse drug reactions are common and sometimes serious in patients with CKD. Many serious adverse drug reactions may be preventable. Some specific pharmacologic classes, particularly antithrombotic agents, are at risk of serious adverse drug reactions.

Abstract
BACKGROUND Recent data have shown that severe acute respiratory syndrome coronavirus 2 can infect renal proximal tubular cells via Angiotensin Converting Enzyme 2 (ACE2) . Our objective was to determine whether Fanconi syndrome is a frequent clinical feature in coronavirus disease 2019 (COVID-19) patients. METHODS A retrospective cohort of 42 laboratory-confirmed COVID-19 patients without history of kidney disease hospitalized in University Hospital of Nancy was investigated. Patients were admitted to the intensive care unit (ICU) (n = 28) or the Medical department (n = 14) and were screened at least once for four markers of proximal tubulopathy. RESULTS The mean (standard deviation) follow-up was 19.7 (±12.2) days. Of the patients, 75% (30/40) showed at least two proximal tubule abnormalities (incomplete Fanconi syndrome). The main disorders were proteinuria (88%, n = 35), renal phosphate leak defined by renal phosphate threshold/glomerular filtration rate (TmPi/GFR) <0.77 (55%, n = 22), hyperuricosuria (43%, n = 17) and normoglycaemic glycosuria (30%, n = 12). At the time of the first renal evaluation, ICU patients presented more frequent (96 versus 62%, P = 0.0095) and more severe (844 ± 343 versus 350 ± 221 mg/g, P = 0.0001) proteinuria, and a trend for an increased number of proximal tubule abnormalities (P = 0.038). During follow-up, they presented a lower nadir of serum phosphate [median (interquartile range) 0.68 (0.43-0.76) versus 0.77 (0.66-1.07) mmol/L, P = 0.044] and Acute kidney Injury (AKI) during the hospitalization (P = 0.045). Fanconi syndrome preceded severe AKI KDIGO Stages 2 and 3 in 88% (7/8) of patients. Proximal tubular abnormalities (such as proteinuria, TmPi/GFR and glycosuria in five, two and two patients, respectively) were not detected anymore in recovering patients before hospital discharge. CONCLUSION Incomplete Fanconi syndrome is highly frequent in COVID-19 patients and precedes AKI or disappears during the recovery phase.

Prognostic value for long-term graft survival of estimated glomerular filtration rate and proteinuria quantified at 3 months after kidney transplantation. Clin Kidney J 2020; 13:791-802. [PMID: 33125000 PMCID: PMC7577768 DOI: 10.1093/ckj/sfaa044] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2019] [Accepted: 03/10/2020] [Indexed: 12/22/2022] Open
Abstract
Background The estimated glomerular filtration rate (eGFR) measured at 1 year is the usual benchmark applied in kidney transplantation (KT). However, acting on earlier eGFR values could help in managing KT during the first post-operative year. We aimed to assess the prognostic value for long-term graft survival of the early (3 months) quantification of eGFR and proteinuria following KT. Methods The 3-, 6- and 12-month eGFR using the Modified Diet in Renal Disease equation (eGFRMDRD) was determined and proteinuria was measured in 754 patients who underwent their first KT between 2000 and 2010 (with a mean follow-up of 8.3 years) in our centre. Adjusted associations with graft survival were estimated using a multivariable Cox model. The predictive accuracy was estimated using the C-index and net reclassification index. These same analyses were measured in a multicentre validation cohort of 1936 patients. Results Both 3-month eGFRMDRD and proteinuria were independent predictors of return to dialysis (all P < 0.05) and there was a strong correlation between eGFR at 3 and 12 months (Spearman’s ρ = 0.76). The predictive accuracy of the 3-month eGFR was within a similar range and did not differ significantly from the 12-month eGFR in either the derivation cohort [C-index 62.6 (range 57.2–68.1) versus 66.0 (range 60.1–71.9), P = 0.41] or the validation cohort [C-index 69.3 (range 66.4–72.1) versus 71.7 (range 68.7–74.6), P = 0.25]. Conclusion The 3-month eGFR was a valuable predictor of the long-term return to dialysis whose predictive accuracy was not significantly less than that of the 12-month eGFR in multicentre cohorts totalling >2500 patients. Three-month outcomes may be useful in randomized controlled trials targeting early therapeutic interventions.

Abstract
Background We compared, in patients contraindicated for kidney transplant, outcomes between those patients who were only on hemodialysis (HD) and those who were given peritoneal dialysis (PD) as first renal replacement therapy (RRT). Design Prospective, population-based cohort study of incident cases of end-stage renal disease between June 1997 and June 1999. Setting A network of dialysis care: NEPHROLOR, that is, all the renal units in Lorraine, one of the 22 French administrative regions (population over 2.3 million people). Participants 387 patients were contraindicated for kidney transplant during the first 2 years of RRT: 284 were on HD, 103 on PD. Mean age was 67.6 ± 11.3 years for HD patients and 70.8 ± 11.4 years for PD patients ( p = 0.015). Main Outcome Measures Mortality until June 2003, hospitalization over the 2 first years of RRT, and Kidney Disease and Quality of Life Short Form (KDQOL-SF) 6 and 12 months after initiation of RRT. Results HD patients were more likely to die from cardiac or cerebrovascular causes, PD from cachexia or withdrawal from dialysis. Whatever mode of RRT, the unadjusted 2-year and 5-year survival rates were similar ( p = 0.98). The rate of total duration of hospital stay per month of RRT was similar in HD and PD groups: 2.7 ± 4.5 and 2.9 ± 4.2 days respectively ( p = 0.7). PD was associated with better quality of life than HD. The dimensions Role limitation due to emotional function, Burden of kidney disease, and Role limitation due to physical function ranked first, second, and third for PD. Conclusion In Lorraine, end-stage renal disease patients who were given PD as first-line RRT had no excess of death risk or hospitalizations, and better quality of life the first year of RRT.

Abstract
In France, the use of peritoneal dialysis (PD) as the first-choice treatment varies greatly between districts, as it is already known to do between countries. Baseline clinical factors associated with choice of first modality were analyzed in 10815 new end-stage renal disease patients in 59 districts. To describe practices at the district level, we used an agglomerative hierarchical classification, with proximity defined by a likelihood-ratio test that compared multivariate logistic regressions of the following factors: age, gender, diabetes, congestive heart failure, severe behavioral disorders, mobility, and employment. To propose a typology, each cluster of districts was described by a multivariate logistic regression. While populations starting PD in France, as elsewhere, are more likely to be young or employed, they are also more likely to be elderly or have congestive heart failure or severe behavioral disorders. Overall, 14% of patients start with PD, but this rate varies significantly across districts, from 0% to 45%. A specific combination of factors was associated with the first-choice modality in each group of districts. This study highlights the lack of consensual medical criteria for this choice and the likelihood that nonmedical factors may explain the observed differences. The high variability suggests that PD can be used in almost all clinical conditions. Accordingly, patient preference should play a more important role in the decision-making process.

Abstract
Background The French Chronic Kidney Disease-Renal Epidemiology and Information Network (CKD-REIN) cohort study was designed to investigate the determinants of prognosis and care of patients referred to nephrologists with moderate and advanced chronic kidney disease (CKD). We examined their baseline risk profile and experience. Methods We collected bioclinical and patient-reported information from 3033 outpatients with CKD and estimated glomerular filtration rates (eGFRs) of 15-60 mL/min/1.73 m2 treated at 40 nationally representative public and private facilities. Results The patients' median age was 69 (60-76) years, 65% were men, their mean eGFR was 33 mL/min/1.73 m2, 43% had diabetes, 24% had a history of acute kidney injury (AKI) and 57% had uncontrolled blood pressure (BP; >140/90 mmHg). Men had worse risk profiles than women and were more likely to be past or current smokers (73% versus 34%) and have cardiovascular disease (59% versus 42%), albuminuria >30 mg/mmol (or proteinuria > 50) (40% versus 30%) (all P < 0.001) and a higher median risk of end-stage renal disease within 5 years, predicted by the kidney failure risk equation {12% [interquartile range (IQR) 3-37%] versus 9% [3-31%], P = 0.008}. During the previous year, 60% of patients reported one-to-two nephrologist visits and four or more general practitioner visits; only 25% saw a dietician and 75% were prescribed five or more medications daily. Physical and mental quality of life (QoL) were poor, with scores <50/100. Conclusions The CKD-REIN study highlights high-risk profiles of cohort members and identifies several priorities, including improving BP control and dietary counselling and increasing doctors' awareness of AKI, polypharmacy and QoL.

Abstract
BACKGROUND Autosomal dominant polycystic kidney disease (ADPKD) is a common genetic disorder associated with progressive enlargement of the kidneys and liver. ADPKD patients may require renal volume reduction, especially before renal transplantation. The standard treatment is unilateral nephrectomy. However, surgery incurs a risk of blood transfusion and alloimmunization. Furthermore, when patients are treated with peritoneal dialysis (PD), surgery is associated with an increased risk of temporary or definitive switch to haemodialysis (HD). Unilateral renal arterial embolization can be used as an alternative approach to nephrectomy. METHODS We performed a multicentre retrospective study to compare the technique of survival of PD after transcatheter renal artery embolization with that of nephrectomy in an ADPKD population. We included ADPKD patients treated with PD submitted to renal volume reduction by either surgery or arterial embolization. Secondary objectives were to compare the frequency and duration of a temporary switch to HD in both groups and the impact of the procedure on PD adequacy parameters. RESULTS More than 700 patient files from 12 centres were screened. Only 37 patients met the inclusion criteria (i.e. treated with PD at the time of renal volume reduction) and were included in the study (21 embolized and 16 nephrectomized). Permanent switch to HD was observed in 6 embolized patients (28.6%) versus 11 nephrectomized patients (68.8%) (P = 0.0001). Renal artery embolization was associated with better technique survival: subdistribution hazard ratio (SHR) 0.29 [95% confidence interval (CI) 0.12-0.75; P = 0.01]. By multivariate analysis, renal volume reduction by embolization and male gender were associated with a decreased risk of switching to HD. After embolization, a decrease in PD adequacy parameters was observed but no embolized patients required temporary HD; the duration of hospitalization was significantly lower [5 days [interquartile range (IQR) 4.0-6.0] in the embolization group versus 8.5 days (IQR 6.0-11.0) in the surgery group. CONCLUSIONS Transcatheter renal artery embolization yields better technique survival of PD in ADPKD patients requiring renal volume reduction.

Abstract
BACKGROUND End-stage renal disease is associated with cardiac remodeling, which is partly reversible after kidney transplantation (KT). We aimed to determine the association of cardiovascular comorbidities or kidney-related factors with cardiac reverse remodeling after KT. METHODS We performed echocardiography in 56 patients (aged 48 ± 15 years, mean ± SD) before and 24 months after undergoing their first KT. Echocardiograms were reviewed using a standardized process with blinding for the patient characteristics and evaluation timing. Multivariable linear regression analysis was used to evaluate the association between comorbidities and changes in cardiac structure and systolic/diastolic function. RESULTS Left ventricular mass index (LVMI) and diastolic parameters did not change significantly, while left ventricular ejection fraction (LVEF) increased from 63.9 to 69.6% (p = 0.046). Multivariable analysis revealed associations of histories of valvular heart disease with a smaller reduction in LVMI (β = -27.3, p = 0.04), of coronary artery disease or heart failure with a smaller increase in LVEF (β = 7.17, p = 0.02), and of diabetes mellitus with less improvement in E wave (β = -0.19, p = 0.05), e' (β = 4.15, p = 0.046), and E/e' (β = -5.00, p < 0.01). CONCLUSION Cardiovascular comorbidities were -associated with less improvement in cardiac structure and function following KT. Our findings suggest that patients with CV comorbidities may experience limited "favorable" reverse cardiac remodeling following KT.

Abstract
Introduction End-stage renal disease is a major public health concern in New Caledonia and in Wallis and Futuna (prevalence value: 2542 per million population in 2017). Spread over the territory, 594 dialysis patients are followed up by nephrologists and partially by telemedicine due to the distance. The aim of our this study was to evaluate the quality of care provided by telemedicine for chronic dialysis patients on Wallis Island, a dialysis unit remote from Noumea (2100 km). Methods We compared two populations of haemodialysis patients, one based in Poindimie in New Caledonia and followed by monthly physical consultation, the other based on Wallis Island and followed by monthly teleconsultation and quarterly on-site consultation. Results From January 2012–December 2017, dialysis adequacy and survival data were recorded for 84 patients: 44 in Poindimie, 40 on Wallis Island. Dialysis adequacy (i.e. clinical, biological parameters) as well as occurrence of vascular access complications were no different regardless of the means of follow-up. During the study, 23 deaths occurred (11 in Poindimie, 12 on Wallis Island; p = 0.464). We did not find any difference in survival at one and six years ( p = 0.46) between the two dialysis units. Evaluation for transplantation was lower for Wallisian patients ( p = 0.042), without impact on the number of patients being transplanted ( p = 0.678). Conclusion Telemedicine is a valuable opportunity for the follow-up of remote chronic haemodialysis patients, allowing them to be treated close to home while ensuring optimal quality of care

Abstract
Background and objectives
Health-related quality of life (HRQoL) is increasingly considered a major outcome in patients with chronic kidney disease (CKD), but the size of its effect on physical and mental health at different disease stages, compared with the general population, is unclear.
Design, setting, participants, and measurements
We compared HRQoL measures in four groups: 2,687 outpatients with moderate (stage 3, estimated glomerular filtration rate [eGFR] 30-60 mL/min/1.73 m2) or advanced (stage 4-5, eGFR < 30 mL/min/1.73 m2) CKD under nephrology care from 40 nationally representative facilities, 1,658 patients with a functioning graft, 1,251 dialysis patients randomly selected from the national REIN registry, and 20,574 participants in the French Decennial Health Survey, representative of the general population.
Results
Mean age (years) was 67, 69, and 55 in patients with non-end-stage CKD, on dialysis, or with transplants, respectively; 60% were men. Age- and gender-standardized health status was perceived as fair or poor in 27% of those with moderate CKD and more than 40% of those with advanced CKD and those on dialysis, compared with 12% in transplant patients and 3% in the general population. Compared with the general population, HRQoL physical scores adjusted for age, gender, education, obesity, and diabetes, were significantly lower, by a factor of 2.2 among patients with moderate CKD, 4.1 among those with advanced CKD, 10.2 among those on dialysis, and 4.1 among those with transplants. The effect was stronger for those younger than 65 years. The mental score was lower only for dialysis patients.
Conclusions
This study highlights the importance of the physical health effects beginning at the moderate stage of CKD. More attention to patients’ CKD-related perceived health is needed.
Key messages
Physical health declined significantly from moderate through end-stage CKD, with impact greatest among the youngest patients. More attention to CKD’s impact on quality of life is needed.

BACKGROUND Atypical hemolytic uremic syndrome (HUS) is associated with high recurrence rates after kidney transplant, with devastating outcomes. In late 2011, experts in France recommended the use of highly individualized complement blockade-based prophylaxis with eculizumab to prevent post-transplant atypical HUS recurrence throughout the country. METHODS To evaluate this strategy's effect on kidney transplant prognosis, we conducted a retrospective multicenter study from a large French nationwide registry, enrolling all adult patients with atypical HUS who had undergone complement analysis and a kidney transplant since January 1, 2007. To assess how atypical HUS epidemiology in France in the eculizumab era evolved, we undertook a population-based cohort study that included all adult patients with atypical HUS (n=397) between 2007 and 2016. RESULTS The first study included 126 kidney transplants performed in 116 patients, 58.7% and 34.1% of which were considered to be at a high and moderate risk of atypical HUS recurrence, respectively. Eculizumab prophylaxis was used in 52 kidney transplants, including 39 at high risk of recurrence. Atypical HUS recurred after 43 (34.1%) of the transplants; in four cases, patients had received eculizumab prophylaxis and in 39 cases they did not. Use of prophylactic eculizumab was independently associated with a significantly reduced risk of recurrence and with significantly longer graft survival. In the second, population-based cohort study, the proportion of transplant recipients among patients with ESKD and atypical HUS sharply increased between 2012 and 2016, from 46.2% to 72.3%, and showed a close correlation with increasing eculizumab use among the transplant recipients. CONCLUSIONS Results from this observational study are consistent with benefit from eculizumab prophylaxis based on pretransplant risk stratification and support the need for a rigorous randomized trial.

Abstract
The Spin-D (Safety and Cardiovascular Efficacy of Spironolactone in Dialysis-Dependent End-Stage Renal Disease) and MiREnDa (Mineralocorticoid Receptor Antagonists in End-Stage Renal Disease) trials taken together provide the reassuring demonstration that up to 25 mg/d spironolactone is reasonably safe, provided maintenance hemodialysis patients are properly monitored and investigators use a per-protocol therapeutic algorithm to manage hyperkalemia. These results should encourage and reassure the investigators of the 2 currently ongoing, large, international, major-outcome clinical trials, both of which are using spironolactone up to 25 mg/d: ACHIEVE (Aldosterone bloCkade for Health Improvement EValuation in End-stage Renal Disease trial; NCT03020303) and ALCHEMIST (ALdosterone antagonist Chronic HEModialysis Interventional Survival Trial; NCT01848639).

Abstract
Chronic inflammation in end-stage renal disease (ESRD) is partly attributed to gut bacterial translocation (GBT) due to loss of intestinal epithelium integrity. Increased levels of circulating lipopolysaccharide (LPS) –a surrogate marker of GBT– contribute to maintain a chronic inflammatory state. However, circulating LPS can be neutralized by lipoproteins and transported to the liver for elimination. While ESRD-associated GBT has been widely described, less is known about its changes and impact on clinical outcome after kidney transplantation (KT). One hundred and forty-six renal transplant recipients with serum samples obtained immediately before and 1 year after transplantation (1-Year post KT) were included. Intestinal epithelium integrity (iFABP), total LPS (by measuring 3-hydroxymyristate), LPS activity (biologically active LPS measured by the LAL assay), inflammatory biomarkers (sCD14 and cytokines), lipoproteins and LPS-binding proteins (LBP and phospholipid transfer protein [PLTP] activity) were simultaneously measured. At 1-Year post KT, iFABP decreased but remained higher than in normal volunteers. Total LPS concentration remained stable while LPS activity decreased. Inflammation biomarkers decreased 1-Year post KT. We concomitantly observed an increase in lipoproteins. Higher sCD14 levels before transplantation was associated with lower incidence of acute rejection. Although GBT remained stable after KT, the contemporary increase in lipoproteins could bind circulating LPS and contribute concomitantly to neutralization of LPS activity, as well as improvement in ESRD-associated chronic inflammation. Chronic exposure to LPS in ESRD could promote endotoxin tolerance and explain why patients with higher pre-transplant sCD14 are less prompt to develop acute rejection after transplantation.

Abstract
OBJECTIVES Kidney transplant recipients are at high-risk for donor-derived infections in the early post-transplant period. Transplant preservation fluid (PF) samples are collected for microbiological analysis. In case of positive PF cultures, the risk for the recipient is unknown and there is no consensus for prescribing prophylactic antibiotics. This nationwide observational study aimed to determine the epidemiology of bacterial and fungal agents in kidney transplant PF cultures and identify risk factors associated with positive PF cultures. METHODS We performed a retrospective observational study on the following data collected from a national database between October 2015 and December 2016: characteristics of donor, recipient, transplantation, infection in donor and PF microbiological data. RESULTS Of 4487 kidney transplant procedures, including 725 (16.2%, 725/4487) from living donors, 20.5% had positive PF cultures (living donors: 1.8%, 13/725; deceased donors: 24.1%, 907/3762). Polymicrobial contamination was found in 59.9% (485/810) of positive PF cultures. Coagulase-negative staphylococci (65.8%, 533/810) and Enterobacteriaceae (28.0%, 227/810) were the most common microorganisms. Factors associated with an increased risk of positive PF cultures in multivariable analysis were (for deceased-donor kidney transplants): intestinal perforation during procurement (OR 4.4, 95% CI 2.1-9.1), multiorgan procurement (OR 1.4, 95% CI 1.1-1.7) and en bloc transplantation (OR 2.5, 95% CI 1.3-4.9). Use of perfusion pump and donor antibiotic therapy were associated with a lower risk of positive PF cultures (OR 0.4, 95% CI 0.3-0.5 and OR 0.6, 95% CI 0.5-0.7, respectively). CONCLUSION In conclusion, 24% of deceased-donor PF cultures were positive, and PF contamination during procurement seemed to be the major cause.

Abstract
Background Elderly patients with chronic kidney disease (CKD) are often excluded from clinical trials; this may affect their use of essential drugs for cardiovascular complications. We sought to assess the impact of age on cardiovascular drug use in elderly patients with CKD. Methods We used baseline data from the Chronic Kidney Disease-Renal Epidemiology and Information Network (CKD-REIN) cohort including 3033 adult patients with CKD Stages 3 and 4. We studied the use of recommended drugs for coronary artery disease (CAD), stroke and atrial fibrillation by age, after adjusting for socio-demographic and clinical conditions. Results The patients’ mean age was 66.8 years (mean estimated glomerular filtration rate 32.9 mL/min/1.73 m2). The prevalence of CAD was 24.5% [81.3% receiving antiplatelet agents, 75.6% renin–angiotensin system (RAS) blockers, 65.4% β-blockers and 81.3% lipid-lowering therapy], that of stroke 10.0% (88.8% receiving antithrombotic drugs) and that of atrial fibrillation 11.1% (69.5% receiving oral anticoagulants). Compared with patients aged <65 years, older age (≥65 years) was associated with greater use of antithrombotic drugs in stroke [adjusted odds ratio (aOR) (95% confidence interval) = 2.83 (1.04–7.73) for patients aged (75–84 years)] and less use of RAS blockers [aOR = 0.39 (0.16–0.89) for patients aged ≥85 years], β-blockers [aOR = 0.31 (0.19–0.53) for patients aged 75–84 years] and lipid-lowering therapy [aOR = 0.39 (0.15–1.02) for patients aged ≥85 years, P for trend = 0.01] in CAD. Older age was not associated with less use of antiplatelet agents in CAD or oral anticoagulants in atrial fibrillation. Conclusions In patients with CKD, older age per se was not associated with the underuse of antithrombotic drugs but was for other major drugs, with a potential impact on cardiovascular outcomes.

Arteriovenous fistula thrombosis is associated with increased all-cause and cardiovascular mortality in haemodialysis patients from the AURORA trial. Clin Kidney J 2019; 13:116-122.

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.
