Clinical Characteristics of Rapid Progression in Asia-Pacific Patients With ADPKD

This study aimed to determine the utility of different methods to predict rapid progressors (RPs) and their clinical characteristics in Asia-Pacific patients with autosomal dominant polycystic kidney disease (ADPKD). This was a multinational retrospective observational cohort study of patients with ADPKD in the Asia-Pacific region. Five hospitals from Australia, China, South Korea, Taiwan, and Turkey participated in this study. RP was defined by European Renal Association-European Dialysis and Transplantation Association (ERA-EDTA) guidelines and compared to slow progressors (SPs). Among 768 patients, 426 patients were RPs. Three hundred six patients met only 1 criterion and 120 patients satisfied multiple criteria for RP. Historical estimated glomerular filtration rate (eGFR) decline fulfilled the criteria for RP in 210 patients. Five patients met the criteria for a historical increase in height-adjusted total kidney volume (TKV). The 210 patients satisfied the criteria for based on kidney volume. During the follow-up period, cyst infections, cyst hemorrhage, and proteinuria occurred more frequently in RP; and 13.9% and 2.1% of RPs and SPs, respectively, progressed to end-stage kidney disease (ESKD). RP criteria based on historical eGFR decline had the strongest correlation with eGFR change over a 2-year follow-up. Various assessment strategies should be used for identifying RPs among Asian-Pacific patients with ADPKD in real-world clinical practice during the follow-up period, cyst infections, cyst hemorrhage, and proteinuria occurred more frequently; and more patients progressed to ESKD in RPs compared with SPs.

#3859 THE TREND OF RENAL REPLACEMENT THERAPY IN N. MACEDONIA FROM 2015 TO 2020: DATA FROM THE ERA-EDTA ANNUAL REGISTRY

Abstract Background and Aims Kidney Failure (KF) is treated with three modalities of renal replacement therapy (RRT): kidney transplantation (Tx), hemodialysis (HD), and peritoneal dialysis (PD). Our study aimed to present the trend of RRT in N. Macedonia from 2015 to 2020. Method The epidemiological retrospective study analyzed the patients with kidney failure by gender, age, etiology of kidney disease, and modality of RRT. The data were processed from the annual reports of the European Renal Association-European Dialysis and Transplant Association (ERA-EDTA). The study patients were divided into group 1 (prevalent) with patients on the RRT at the current year, group 2 (incidence at Day 1) with patients on the RRT with a duration of at least 1 day, and group 3 (incidence at Day 91) with patients on the RRT with a duration beyond 91 days. Results A total of 10395 patients were analyzed with a mean age of 59.2 ± 9.5 years (median 60.4 years), of which 60.2% were male. From 2015 to 2019, there was an increasing trend in all groups, and most patients were reported in 2019. In group 1, 1598 patients were registered in 2015, and 1762 patients were registered in 2020, which is an increasing trend of 10.3%. The number of patients in group 2 was increasing every following year, with the highest growth in 2019 up to 12.1%, compared to 2018. The number of patients in group 3 also showed significant growth from 253 patients in 2015 to 324 patients in 2019, but there was a decrease of 16.4% in 2020 (271 patients). Deviations are observed in 2020, with a decrease in the number of patients in group 1 and group 3, as well as a slowdown in the growth dynamics of patients in group 2, which might be associated with the start of the SARS-CoV-2 pandemic. According to the modality, most of the patients (84.7%) were on HD in 2015 and 85.9% in 2020. The most frequent age group of patients was from 45 to 64 years, from 36.3% to 49.4%. There was an increasing trend of patients from older age groups (over 64 years) and male patients. The increasing number of patients from the age group 75+ years was also noted in all groups. Etiology of kidney disease: hypertension (25.8%) and diabetes mellitus (17.4%) were the leading causes of KF in patients requiring RRT. Conclusion The study showed a constantly increasing trend of patients with KF requiring RRT. The largest number of patients were men, aged from 45 to 64 years. Hypertension and diabetes mellitus were the leading causes of KF, and most of the patients were treated with HD.

Management of antineutrophil cytoplasmic antibody-associated vasculitis: a review of recent guidelines.

Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is an autoimmune rheumatic disease consisting of three discrete diagnoses of microscopic polyangiitis, granulomatosis with polyangiitis, and eosinophilic granulomatosis with polyangiitis. Among diseases treated in a rheumatology department, AAV has poor clinical outcomes, with high rates of mortality and progression to end-stage renal disease and frequent disease relapse. Due to the frequent negative patient outcomes, optimal therapeutic strategies are essential in the management of AAV. In the present review, four guidelines for management of AAV are summarized: British Society for Rheumatology (BSR) and British Health Professionals in Rheumatology (BHPR) guideline for the management of adults with AAV; European League Against Rheumatism (EULAR)/European Renal Association-European Dialysis and Transplant Association (ERA-EDTA) recommendation for the management of AAV; 2021 American College of Rheumatology (ACR)/Vasculitis Foundation Guideline for the Management of AAV; Kidney Disease: Improving Global Outcome (KDIGO) 2021 Clinical Practice Guideline for the Management of Glomerular Diseases, which will aid in clinicians' medical decisions. Finally, the summary of the 2022 Update of the EULAR Recommendations on the Management of AAV, presented in the EULAR Congress 2022 is also introduced.

Mesures hors centre de la pression artérielle chez les hémodialysés chroniques : faisabilité et comparaison des méthodes

The European Renal Association-European Dialysis and Transplant Association (ERA-EDTA)/European Society of Hypertension (ESH) recommends out-of-center blood pressure measurements, self-blood pressure measurement or ambulatory blood pressure measurement in dialysis patients. However, the feasibility of out-of-center blood pressure measurements in routine care is not known. The objective of our study was to quantify it as “a priori” i.e. the percentage of hemodialysis to whom out-of-center blood pressure measurements can be proposed and who accept it, as “a posteriori”, i.e. the percentage of out-of-center blood pressure measurements made and valid. A systematic out-of-center blood pressure measurements program was implemented from April to October 2019 in our chronic hemodialysis structures. It was proposed to each dialysis patient to carry out after education, an self-blood pressure measurement (Omron M3®), from 2 measurements, to 1 to 2minutes interval, mornings and evenings of 6days without dialysis (validity: 15 measures). Apart from arrhythmic patients, to all patients “not eligible” for self-blood pressure measurement (visually impaired, hemiplegic, neuropsychological disorders, language barrier), a 44-hour ambulatory blood pressure measurement (Microlife WatchBP 03®) was proposed separating 2 hemodialysis sessions; measures every 15minutes from 7 a.m. to 10 p.m. and 30minutes from 10 p.m. to 7 a.m. (validity: 40 measurements/day and 14/night). This is a study evaluating practices recommended for routine care in 18-year-old hemodialysis, having given their consent to the collection and analysis of the data. One hundred twenty nine patients were treated with chronic hemodialysis in our structures during the out-of-center blood pressure measurements campaign. Out-of-center blood pressure measurements could not be done in 21 patients (4 deceased, 2 transplanted and 4 absent before evaluation; 7 arrhythmics; 3 refusals and 1 multiple-disabled). Of these 108 patients (sex ratio 1.25; 69.3±13.5 years), 23 were ineligible for self-blood pressure measurement (visually impaired, neuro- and/or psychological disorders, language barrier). Due to 4 self-blood pressure measurement failures, the feasibility of the self-blood pressure measurement (n=81/129) is 62.8 % (CI95% 54.2–70.7). Of the 24 ambulatory blood pressure measurements performed (23 among those not eligible for self-blood pressure measurement and 1 failure of self-blood pressure measurement), 19 were valid. The “a posteriori” feasibility of out-of-center blood pressure measurements (n=100/129) is 77.5 % (CI95% 69.6–83.4). The feasibility of out-of-center blood pressure measurements in hemodialysis patients is good, making the application of the recommendations possible.

Diagnosis and management of osteoporosis in chronic kidney disease stages 4 to 5D: a call for a shift from nihilism to pragmatism.

The European Renal Association-European Dialysis and Transplant Association (ERA-EDTA) CKD-MBD working group, in collaboration with the Committee of Scientific Advisors of the International Osteoporosis Foundation, published a position paper for the diagnosis and management of osteoporosis in patients with CKD stages 4-5D (eGFR < 30 ml/min 1.73 m2). The present article reports and summarizes the main recommendations included in this 2021 document. The following areas are reviewed: diagnosis of osteoporosis; risk factors for fragility fractures; fracture risk assessment; intervention thresholds for pharmacological intervention; general and pharmacological management of osteoporosis; monitoring of treatment, and systems of care, all in patients with CKD stages 4-5D. Guidance is provided for clinicians caring for CKD stages 4-5D patients with osteoporosis, allowing for a pragmatic individualized diagnostic and therapeutic approach as an alternative to current variations in care and treatment nihilism.

Tweet me: conferencing in the era of COVID-19 and 280 characters.

The European Renal Association – European Dialysis and Transplant Association (ERA-EDTA) Social Media (SoMe) Team provides Twitter coverage of the annual congress. During the coronavirus disease 2019 (COVID-19) pandemic, #ERAEDTA20 was the first major Nephrology congress to be delivered virtually. The effect of The SoMe Team and the consequences of the COVID-19 pandemic have not been explored previously. Tweets of the ERA-EDTA congresses 2016–20, using official hashtags, were evaluated. Metadata of each tweet were collected prospectively; original tweets, retweets and evidence-based tweets were identified. The gender of tweet author and location of Twitter activity were established. Network maps were created to ascertain the degree of polarization between the 2019 and 2020 Twitter activity, using Gephi 0.9.2.Between 2016 and 2019, the total number of tweets and the number of tweet authors increased, as did the proportion of female authors (20% versus 27%). In 2019, there were fewer multimedia and evidence-based tweets: 8% versus 20% in 2016. Globally, there were fewer Nephrology conferences in 2020 and the number of tweets per day reduced by 53% from 2019. In 2020, The ERA-EDTA congress saw an increase in authors of 9% and only an 8% reduction in tweets. It was easier to disseminate information in 2020, measured by increased correlation coefficient (0.14 versus 0.12 in 2019). A higher proportion of countries was represented (n = 55 versus n = 48 in 2019) and a higher proportion of tweets came from women. In conclusion, the introduction of SoMe Team was associated with increased usage of Twitter and ease of information dissemination. Compared with #nephtwitter activity as a whole in 2020, SoMe Team has mitigated some of the pandemic's deleterious effects in scientific dissemination, relevant to Nephrology.

Systemic lupus erythematosus

Systemic lupus erythematosus (SLE) is a highly variable disease driven by the tendency to form very different types of antibody. This sometimes leads to an exaggerated respect for the complexity of the disease symptoms and to uncertainty in dealing with affected patients; however, nowadays the most important measures in the diagnosis and management of the disease can be broken down to a manageable extent. In this respect, the new recommendations of the European League Against Rheumatism (EULAR) on SLE and the recommendations on lupus nephritis jointly developed by EULAR and the European Renal Association/European Dialysis and Transplant Association (ERA/EDTA) are helpful, as are the new classification criteria from EULAR and the American College of Rheumatology (ACR). In this article the core points of these publications are summarized and contemporary SLE management is presented. As a rule, SLE can be effectively treated when managed in this way.

The ERA-EDTA Registry Annual Report 2018: a summary.

BackgroundThe European Renal Association – European Dialysis and Transplant Association (ERA-EDTA) Registry collects data on kidney replacement therapy (KRT) via national and regional renal registries in Europe and countries bordering the Mediterranean Sea. This article summarizes the 2018 ERA-EDTA Registry Annual Report, and describes the epidemiology of KRT for kidney failure in 34 countries.MethodsIndividual patient data on patients undergoing KRT in 2018 were provided by 34 national or regional renal registries and aggregated data by 17 registries. The incidence and prevalence of KRT, the kidney transplantation activity and the survival probabilities of these patients were calculated.ResultsIn 2018, the ERA-EDTA Registry covered a general population of 636 million people. Overall, the incidence of KRT for kidney failure was 129 per million population (p.m.p.), 62% of patients were men, 51% were ≥65 years of age and 20% had diabetes mellitus as cause of kidney failure. Treatment modality at the onset of KRT was haemodialysis (HD) for 84%, peritoneal dialysis (PD) for 11% and pre-emptive kidney transplantation for 5% of patients. On 31 December 2018, the prevalence of KRT was 897 p.m.p., with 57% of patients on HD, 5% on PD and 38% living with a kidney transplant. The transplant rate in 2018 was 35 p.m.p.: 68% received a kidney from a deceased donor, 30% from a living donor and for 2% the donor source was unknown. For patients commencing dialysis during 2009–13, the unadjusted 5-year survival probability was 42.6%. For patients receiving a kidney transplant within this period, the unadjusted 5-year survival probability was 86.6% for recipients of deceased donor grafts and 93.9% for recipients of living donor grafts.

The association of living donor source with patient and graft survival among kidney transplant recipients in the ERA-EDTA Registry - a retrospective study.

SummaryIn this study we aimed to compare patient and graft survival of kidney transplant recipients who received a kidney from a living‐related donor (LRD) or living‐unrelated donor (LUD). Adult patients in the ERA‐EDTA Registry who received their first kidney transplant in 1998–2017 were included. Ten‐year patient and graft survival were compared between LRD and LUD transplants using Cox regression analysis. In total, 14 370 patients received a kidney from a living donor. Of those, 9212 (64.1%) grafts were from a LRD, 5063 (35.2%) from a LUD and for 95 (0.7%), the donor type was unknown. Unadjusted five‐year risks of death and graft failure (including death as event) were lower for LRD transplants than for LUD grafts: 4.2% (95% confidence interval [CI]: 3.7–4.6) and 10.8% (95% CI: 10.1–11.5) versus 6.5% (95% CI: 5.7–7.4) and 12.2% (95% CI: 11.2–13.3), respectively. However, after adjusting for potential confounders, associations disappeared with hazard ratios of 0.99 (95% CI: 0.87–1.13) for patient survival and 1.03 (95% CI: 0.94–1.14) for graft survival. Unadjusted risk of death‐censored graft failure was similar, but after adjustment, it was higher for LUD transplants (1.19; 95% CI: 1.04–1.35). In conclusion, patient and graft survival of LRD and LUD kidney transplant recipients was similar, whereas death‐censored graft failure was higher in LUD. These findings confirm the importance of both living kidney donor types.

Survival improvements for Europeans with ESKD

Excess end-stage kidney disease-related mortality rates have decreased substantially over time among adults recorded in the European Renal Association-European Dialysis and Transplant Association (ERA-EDTA) Registry, with the largest relative decreases in the youngest adults and the largest absolute decreases in the oldest adults. While improvements were observed among patients of all ages being treated with dialysis, patients with kidney transplants showed no clear improvements, and those≥65 years old showed a worrying increase in excess mortality over time.

Funding kidney research as a public health priority: challenges and opportunities

Medical societies have a social responsibility to disseminate knowledge and inform health authorities on threats to public health posed by various diseases. Advocacy for health protection programmes and for medical research funding is now embedded into the missions of most scientific societies. To promote kidney research funding in Europe, the European Renal Association - European Dialysis and Transplant Association (ERA-EDTA), rather than acting as an individual society advocating for the fight against kidney disease, has actively helped to create an alliance of national associations centred on kidney diseases, the European Kidney Health Alliance (EKHA), and joined the Biomedical Alliance (BMA). The ERA-EDTA is fully committed to supporting its working groups (WGs) and consortia of its members to allow them to produce valuable kidney research. The framing and formalization of projects, and the regulatory issues related to submission to the European Commission, are complex. To help WGs to gain expert advice from agencies with specific know-how, the ERA-EDTA has adopted a competitive approach. The best research projects proposed by WGs and consortia of other European investigators will receive seed funding to cover the costs of consultancy by expert agencies. Via its broader platforms, the EKHA and the BMA, the ERA-EDTA will strive towards broader recognition of kidney disease and related clusters of non-communicable diseases, by European and national agencies, as major threats to the qualities of life of their populations and their economies.

DNA methylation modulates allograft survival and acute rejection after renal transplantation by regulating the mTOR pathway

Acute rejection (AR) can lead to allograft dysfunction following renal transplantation, despite immunosuppressive treatments. Accumulating evidence points out a role for epigenetic modification in immune responses. However, the mechanism and contribution of DNA methylation in allograft survival remain unclear. In this study, we followed up patients who successively experienced end‐stage renal disease, renal transplantation with allograft function or dysfunction, and hemodialysis. Peripheral blood mononuclear cells were collected at different time points for analysis of the DNA methylation. Epigenetic modifier analysis was also performed to explore its effect of methylation in a mouse model of AR. Compared with the allograft‐stable cohort, patients who experienced AR‐induced allograft dysfunction demonstrated more changes in methylation patterns. Pathway analysis revealed that the hypermethylated areas in the allograft dysfunction group were associated with genes related to the mechanistic target of rapamycin (mTOR) signaling pathway. Moreover, in the mouse AR model, treatment with the DNA methyltransferase inhibitor—decitabine regulated the Th1/2/17/regulatory T cell (Treg cell) immune response via its demethylating role in the suppressing the activity of the mTOR pathway, which ultimately ameliorated renal allograft‐related inflammatory injuries. These results revealed that changes in methylation accompany AR‐induced allograft dysfunction after renal transplantation. Epigenetics may provide new insights into predicting and improving allograft survival.

The ERA-EDTA Registry Annual Report 2017: a summary.

BackgroundThis article presents a summary of the 2017 Annual Report of the European Renal Association–European Dialysis and Transplant Association (ERA-EDTA) Registry and describes the epidemiology of renal replacement therapy (RRT) for end-stage renal disease (ESRD) in 37 countries.MethodsThe ERA-EDTA Registry received individual patient data on patients undergoing RRT for ESRD in 2017 from 32 national or regional renal registries and aggregated data from 21 registries. The incidence and prevalence of RRT, kidney transplantation activity and survival probabilities of these patients were calculated.ResultsIn 2017, the ERA-EDTA Registry covered a general population of 694 million people. The incidence of RRT for ESRD was 127 per million population (pmp), ranging from 37 pmp in Ukraine to 252 pmp in Greece. A total of 62% of patients were men, 52% were ≥65 years of age and 23% had diabetes mellitus as the primary renal disease. The treatment modality at the onset of RRT was haemodialysis for 85% of patients. On 31 December 2017, the prevalence of RRT was 854 pmp, ranging from 210 pmp in Ukraine to 1965 pmp in Portugal. The transplant rate in 2017 was 33 pmp, ranging from 3 pmp in Ukraine to 103 pmp in the Spanish region of Catalonia. For patients commencing RRT during 2008–12, the unadjusted 5-year patient survival probability for all RRT modalities combined was 50.8%.

Data from the ERA-EDTA Registry were examined for trends in excess mortality in European adults on kidney replacement therapy

The objective of this study was to investigate whether the improvement in survival seen in patients on kidney replacement therapy reflects the enhanced survival of the general population. Patient and general population statistics were obtained from the European Renal Association-European Dialysis and Transplant Association (ERA-EDTA) Registry and the World Health Organization databases, respectively. Relative survival models were composed to examine trends over time in all-cause and cause-specific excess mortality, stratified by age and modality of kidney replacement therapy, and adjusted for sex, primary kidney disease and country. In total, 280,075 adult patients started kidney replacement therapy between 2002 and 2015. The excess mortality risk in these patients decreased by 16% per five years (relative excess mortality risk (RER) 0.84; 95% confidence interval 0.83-0.84). This reflected a 14% risk reduction in dialysis patients (RER 0.86; 0.85-0.86), and a 16% increase in kidney transplant recipients (RER 1.16; 1.07-1.26). Patients on dialysis showed a decrease in excess mortality risk of 28% per five years for atheromatous cardiovascular disease as the cause of death (RER 0.72; 0.70-0.74), 10% for non-atheromatous cardiovascular disease (RER 0.90; 0.88-0.92) and 10% for infections (RER 0.90; 0.87-0.92). Kidney transplant recipients showed stable excess mortality risks for most causes of death, although it did worsen in some subgroups. Thus, the increase in survival in patients on kidney replacement therapy is not only due to enhanced survival in the general population, but also due to improved survival in the patient population, primarily in dialysis patients.

P0085MAYO AND PRO-PKD SCORE CONCORDANCE FOR PROGRESSION OF RENAL FALIURE EVALUATION IN ADPKD PATIENTS

Abstract Background and Aims Autosomal dominant polycystic kidney disease (ADPKD) is a multisystemic disease characterized by the progressive development of bilateral renal cysts, resulting in enlargement of the kidney volume due to cystic formations, hypertension, haematuria, and loss of renal function. Recent advances in genomics have contributed to have a better understanding of the pathogenesis of the disease suggesting new treatment strategies to inhibit or delay cysts formation and expansion.Since 2015, the European Medicines Agency approved Vaptans as therapy to slow the growth of kidney volume and the decline in kidney function in patients defined rapid progressors. In 2016 European Renal Association-European Dialysis and Transplant Association (ERA-EDTA) Working Groups on Inherited Kidney Disorders and European Renal Best Practice (WGIKD/ ERBP) published a position statement for definition of rapid progression. These recommendations included two algorithms to assess indications for initiation of ADPKD treatment. They selected three criteria based on: 1) the relationship between TKV(total kidney volume) and the decline in renal function according CRISP study, using Mayo Clinic Score 2) eGFR slope with an average ≥2.5 mL/min/1.73 m2/ yearly loss of renal function over a period of 5 yearsor 3) the link between genetic mutation and clinical information study using Propkd score.A 5 –years follow-up is not always available to achieve the criteria for rapid progressor, therefore the use of scores in clinical practice is widespread.In this scenario both scores (MAYO and PRO-PKD) are able to define rapid progressor patients and it is possible to use them alternatively as reported in literature. The aim of this study is to evaluate the prognostic scores in a real life experience. Method All ADPKD patients in follow-up in our Nephrology Unit from January 2017 to July 2019 were included in the study. Descriptive statistics were used to summarize demographic and clinical characteristics. Therefore we classified them for TKV, genetic mutation, renal function, Mayo score and Propkd score. Rapid progression was defined as 1C-D-E Mayo and high risk PRO PKD while non rapid progressors was 1A-1B mayo and low and intermediate PRO-PKD. Kappa statistic was used to determinate the concordance between Mayo and PROPKD score. Change in renal function within patients with the same class of score where analysed using Paired Wilcoxon signed rank sum test. Results We examined75 patients, 78% between 18-50 years, equally distributed for sex. The results shown thatdisease was more frequent familiar (88 %) witha percentage of mutations of PKD1 versus PKD2 mutation (90,7%/9,3%). 31patients (41%) had a GFR between 45-89 ml/min, 52patients (69%) achieved the criteria for nephromegaly according guideline (TKV &amp;gt; 750CC). Respectively 76% (57pt) and 21%(16pt) were defined as rapid progressors for Mayo score ad Propkd score. The slope of GFR was worse in patients defined rapid progressor in spite of non rapidprogressor according MAYO score (-2,8 ml/min vs 0,3 ml/min) as for propkd classification (-3 vs - 1,75ml/min). Only for 15 patients the results were concordant for this two scores,43 patients identified as rapid progressor for Mayo score were non rapid progressor for Propkd score, in the same way 2 patients classified for Propkd were not rapid progressor for Mayo score. K of Coen of 0,07. Conclusion High risk patients present a significant decline in renal function in the first year with both score systems, confirming results of previous studies. Currently the scores used to define rapid progressors select patients differently. Concordance between scores il low (K of Cohen 0,076). The Propkd score is more selective compared to Mayo score. NeverthelessProPKD allows to identify some rapid progressor patients excluded from the use of the Mayo score only. The combined use of scoring may however increases the ability to identify progressive patients.

Renal Volume in ADPKD Patient Evaluation.

The clinical manifestations of ADPKD are related to the growth of renal cysts. Renal volume has been recognised as the biomarker that is able to identify those patients at risk of complications (hypertension and haematuria) and at risk of progression to End Stage Renal Disease (ESRD). Recently, several scores have been introduced to predict the evolution of ADPKD. The Mayo Clinic Group developed a classification based on renal volume as measured by CT or MRI and corrected for age and height (Ht-TKV); this allowed predicting the evolution of the disease, but it has not been fully validated so far. In addition, it is used to identify patients labelled as “fast progressors” and eligible for Tolvaptan therapy according to the European Renal Association-European Dialysis and Transplant Association (ERA-EDTA) recommendations. We studied 80 patients who underwent MRI and had been classified as ADPKD typical form (class 1A-1E). A significant correlation between renal volume, hypertension, and low GFR was found (p < 0.005). A progressive increase in disease severity has been found across the different Mayo classes; 41.2% were eligible for Tolvaptan therapy. The results demonstrate that the Mayo method is easy to perform and provides valid information in order to identify with rapidly progressing disease.

Does established vascular kidney disease exist?

Does established vascular kidney disease exist?

Management of atrial fibrillation in patients with chronic kidney disease in clinical practice: a joint European Heart Rhythm Association (EHRA) and European Renal Association/European Dialysis and Transplantation Association (ERA/EDTA) physician-based survey.

The European Heart Rhythm Association (EHRA) and European Renal Association/European Dialysis and Transplantation Association (ERA/EDTA) jointly conducted a physician-based survey to gain insight into the management of atrial fibrillation (AF) in patients with chronic kidney disease (CKD) and adherence to current European Society of Cardiology AF Guidelines in contemporary clinical practice. Physician-based survey conducted during an 8-week period using an internet-based questionnaire sent to all EHRA and ERA/EDTA members, with voluntary and anonymous responses. Among 306 physicians (160 EHRA and 146 ERA/EDTA members; 56 countries), a multidisciplinary team for management of AF-CKD patients was available to only 20/300 respondents (6.7%) and 132/295 (44.7%) routinely screened CKD patients for AF. Oral anticoagulation (OAC) use was based on individual stroke risk in mild/moderate CKD but on shared decision-making in advanced CKD. The CHA2DS2-VASc score-based decisions were more common among cardiologists, with substantial intra- and inter-specialty heterogeneity in the use and dosing of specific OAC drugs across CKD stages, heterogeneous strategies for OAC monitoring (especially among nephrologists) and a modest impact of CKD on rate and rhythm control treatment decisions. The HAS-BLED score was generally not a determinant of OAC prescribing. Our survey provided important insights into contemporary management of AF patients with CKD in clinical practice, revealing certain differences between nephrologists and cardiologists and highlighting shared and specific knowledge gaps and unmet needs. These findings emphasize the need for streamlining the care for AF patients across different specialties and may inform development of tailored education interventions.
