BACKGROUND In 2020, the COVID-19 pandemic caused disruptions in kidney replacement therapy (KRT) services worldwide. The aim of this study was to assess the effect of the COVID-19 pandemic in 2020 on the incidence of KRT, kidney transplantation activity, mortality and prevalence of KRT across Europe. METHODS Patients receiving KRT were included from 17 countries providing data to the European Renal Association Registry. The epidemiology of KRT in 2020 was compared with average data from the period 2017-2019. Also changes occurring during the first and second wave of the pandemic were explored. RESULTS The incidence of KRT was 6.2% lower in 2020 compared with 2017-2019, with the lowest point (-22.7%) during the first wave in April. The decrease varied across countries, was smaller in males (-5.2%) than in females (-8.2%), and was moderate for peritoneal dialysis (-3.7%) and haemodialysis (-5.4%), but substantial for pre-emptive kidney transplantation (-23.6%). The kidney transplantation rate decreased by 22.5%, reaching a nadir of -80.1% during the first wave, and most for living donor kidney transplants (-30.5%). While in most countries the kidney transplantation rate decreased, in the Nordic/Baltic countries and Greece there was no clear decline. In dialysis patients, mortality increased by 11.4%, and was highest in those aged 65-74 years (16.1%), in those with diabetes as primary renal disease (15.1%), and in those on haemodialysis (12.4%). In transplant recipients, the mortality was 25.8% higher, but there were no subgroups that stood out. In contrast to the rising prevalence of KRT observed over the past decades across Europe, the prevalence at the end of 2020 (N=317787) resembled that of 2019 (N=317077). CONCLUSION The COVID-19 pandemic has had a substantial impact on the incidence of KRT, kidney transplant activity, mortality of KRT, and prevalence of KRT in Europe with variations across countries.

BACKGROUND AND HYPOTHESIS This paper compares the most recent data on the incidence and prevalence of kidney replacement therapy (KRT), kidney transplantation rates, and mortality on KRT from Europe to those from the United States (US), including comparisons of treatment modalities (haemodialysis (HD), peritoneal dialysis (PD), and kidney transplantation (KTx)). METHODS Data were derived from the annual reports of the European Renal Association (ERA) Registry and the United States Renal Data System (USRDS). The European data include information from national and regional renal registries providing the ERA Registry with individual patient data. Additional analyses were performed to present results for all participating European countries together. RESULTS In 2021, the KRT incidence in the US (409.7 per million population (pmp)) was almost 3-fold higher than in Europe (144.4 pmp). Despite the substantial difference in KRT incidence, approximately the same proportion of patients initiated HD (Europe: 82%, US: 84%), PD (14%; 13% respectively), or underwent pre-emptive KTx (4%; 3% respectively). The KRT prevalence in the US (2436.1 pmp) was 2-fold higher than in Europe (1187.8 pmp). Within Europe, approximately half of all prevalent patients were living with a functioning graft (47%), while in the US, this was one third (32%). The number of kidney transplantations performed was almost twice as high in the US (77.0 pmp) compared to Europe (41.6 pmp). The mortality of patients receiving KRT was 1.6-fold higher in the US (157.3 per 1000 patient years) compared to Europe (98.7 per 1000 patient years). CONCLUSIONS The US had a much higher KRT incidence, prevalence, and mortality compared to Europe, and despite a higher kidney transplantation rate, a lower proportion of prevalent patients with a functioning graft.

BACKGROUND AND HYPOTHESIS Primary glomerular disease (PGD) is a major cause of end-stage kidney disease (ESKD) leading to kidney replacement therapy (KRT). We aimed to describe incidence (trends) in individuals starting KRT for ESKD due to PGD and to examine their survival and causes of death. METHODS We used data from the European Renal Association (ERA) Registry on 69 854 patients who started KRT for ESKD due to PGD between 2000 and 2019. ERA primary renal disease codes were used to define six PGD subgroups. We examined age and sex standardized incidence, trend of the incidence, and survival. RESULTS The standardized incidence of KRT for ESKD due to PGD was 16.6 per million population (pmp), ranging from 8.6 pmp in Serbia to 20.0 pmp in France. IgA nephropathy (IgAN) and focal segmental glomerulosclerosis (FSGS) had the highest incidence of 4.6 pmp and 2.6 pmp, respectively. Histologically non-examined PGDs represented over 50% of cases in Serbia, Bosnia and Herzegovina, and Romania and were also common in Greece, Estonia, Belgium, and Sweden. The incidence declined from 18.6 pmp in 2000 to 14.5 pmp in 2013, after which it stabilized. All PGD subgroups had five-year survival probabilities above 50%, with crescentic glomerulonephritis having the highest risk of death (adjusted hazard ratio: 1.8 [95% confidence interval: 1.6-1.9]) compared with IgAN. Cardiovascular disease was the most common cause of death (33.9%). CONCLUSION The incidence of KRT for ESKD due to PGD showed large differences between countries and was highest and increasing for IgAN and FSGS. Lack of kidney biopsy facilities in some countries may have affected accurate assignment of the cause of ESKD. The recognition of the incidence and outcomes of KRT among different PGD subgroups may contribute to a more individualized patient care approach.

ABSTRACT Background The European Renal Association (ERA) Registry collects data on kidney replacement therapy (KRT) in patients with end-stage kidney disease (ESKD). This paper is a summary of the ERA Registry Annual Report 2021, including a comparison across treatment modalities. Methods Data was collected from 54 national and regional registries from 36 countries, of which 35 registries from 18 countries contributed individual patient data and 19 registries from 19 countries contributed aggregated data. Using this data, incidence and prevalence of KRT, kidney transplantation rates, survival probabilities and expected remaining lifetimes were calculated. Result In 2021, 533.2 million people in the general population were covered by the ERA Registry. The incidence of KRT was 145 per million population (pmp). In incident patients, 55% were 65 years or older, 64% were male, and the most common primary renal disease (PRD) was diabetes (22%). The prevalence of KRT was 1040 pmp. In prevalent patients, 47% were 65 years or older, 62% were male, and the most common PRDs were diabetes and glomerulonephritis/sclerosis (both 16%). On 31 December 2021, 56% of patients received haemodialysis, 5% received peritoneal dialysis, and 39% were living with a functioning graft. The kidney transplantation rate in 2021 was 37 pmp, a majority coming from deceased donors (66%). For patients initiating KRT between 2012–2016, 5-year survival probability was 52%. Compared to the general population, life expectancy was 65% and 68% shorter for males and females receiving dialysis, and 40% and 43% shorter for males and females living with a functioning graft.

Dear Colleagues, We are delighted to share another issue (September 2023, Volume 29, Issue 3) of the European Journal of Therapeutics (Eur J Ther). We believe this issue’s valuable and exciting works will be read with interest. As you will notice at first glance, you will see that this issue contains many editorials and letters to the editor, unlike the previous issues. As the new editorial team, we aim to publish current developments, interesting notes, or important historical anecdotes in medicine as Editorials, Special Editorials, or Letters to the Editor. We would like to inform you that you can submit all of your articles that meet these criteria to our journal. In this editorial, we would like to share the developments that we think are important for Eur J Ther, since our previous editorial [1]. First, we would like to share that the Eur J Ther is approved for inclusion in ERIH PLUS [2]. Moreover, the Eur J Ther now also appears in the Journal Section of the ResearchGate [3]. In this way, it will be possible to follow the Eur J Ther through ResearchGate. We wish to inform you that our editorial team is diligently striving to deliver enhanced advancements in the forthcoming editions. Another significant development is that an application to the Index Copernicus was submitted for the Eur J Ther on July 31, 2023 [4]. In the previous issue, it was reported that some of the cited references made to the previous articles published in the Eur J Ther were not reflected in the Web of Science, and applications via “data changes form” were made to correct them [1]. Most of these applications have been completed, updated in the Web of Science database, and corrected missing references. With these corrections and new citations in the last three to four months, the average per-item value (total number of citations for all articles divided by the number of articles) of the Eur J Ther has increased from 0.52 to 0.78 [5]. In addition, the journal’s H-Index has risen from 8 to 10. The current metrics of Eur J Ther in the Web of Science are as follows, as of August 16, 2023 [5]. Total number of publications: 800 (between 2007 to 2023) Citing Articles (total): 593 Citing Articles (without self-citations): 558 Times Cited (total): 620 Times Cited (without self-citations): 570 Average per item: 0.78 (620/800) H-Index: 10 Although these metrics may be insufficient for Eur J Ther, which has been published for over thirty years, we, the New Editorial Team, anticipate that we can achieve better levels in the long run with our updated policies. Another significant development is that the Journal Impact Factor value of the Eur J Ther was calculated for the first time, and this value was 0.3. As is known, the Web of Science calculated Journal Impact Factors for the first time for journals in the E-SCI index as of 2023 [6]. Although a Journal Impact Factor of 0.3 is not satisfactory, it is not bad for a journal whose Journal Impact Factor is calculated for the first time. On the other hand, we believe that this value will increase in the coming years, as essential and valuable studies will be published in our journal. The previous issue reported that there are significant changes in the Editorial Board of Eur J Ther [1, 7]. We are pleased to inform you that we continue to expand our editorial team in this issue.

Dear Colleagues, In the previous editorial paper published by Balat et al. [1] as an Early View Article a few months ago, it was reported that there were changes in the Editorial Team of the European Journal of Therapeutics (Eur J Ther). During these few months, while the preparations for the new issue (June 2023, volume 29, Issue 2) continued, the editorial board also was revised. We would like to inform you that the Editorial Board has been strengthened by academics who are competent in their fields from many countries of the world and will continue to be strengthened in the future. As it is known, Eur J Ther started broadcasting in 1990 as a Journal of the Faculty of Medicine University of Gaziantep (In Turkish: Gaziantep Üniversitesi Tıp Fakültesi Dergisi). In the first paper titled “While Starting” (In Turkish: Başlarken) of the first issue, Prof. Sabri Güngör, who was the first Editor-in-Chief, stated that the aim of the journal is to have an influential place in the field of science [2]. Over the past three decades, the journal has continued to advance. At the present time, it is inevitable to reorganise the editorial board of the journal and enrich it with leading international editors in order to move the journal to better places. This editorial will explain essential developments in the journal in the last few months, and the new Editorial Board Members of the Eur J Ther will be introduced. Changes are inevitable, and we are delighted to announce that this issue marks several significant improvements. Specifically, we bolstered our editorial team with esteemed international academics and expanded our pool of referees. Consequently, the evaluation period for the submitted articles was significantly reduced. In the last two months, the journal metrics are as follows: Acceptance rate: %29 Average time until the final decision: 24.4 days Average time to publish as Accepted/Early View Article, after acceptance: 4.8 days. Thanks to these improvements, as you will notice, there are 25 articles in this issue. In this way, this issue has been the issue in which most articles have been published so far. In addition, applications were made to DOAJ (Directory of Open Access Journals) and BASE (Bielefeld Academic Search Engine), among the most essential open-access databases in the world, in May 2023. Moreover, cited references to the previous and/or alternative names of the journal (Gaziantep Medical Journal, Gaziantep Med J, Gaziantep Tıp Dergisi and Gaziantep Üniversitesi Tıp Fakültesi Dergisi) in Web of Science that were not reflected in the journal metrics were identified and reported to the Web of Science. Some of these correction requests have been finalized and corrected, and thus the total number of citations and the H-index of the journal increased [3]. After all these data are updated, it will be seen that the citation values of the Eur J Ther will increase even more. We will also update the guidelines for the authors and reviewers with respect to the ICMJE [4] and EQUATOR Network [5], which will enhance the quality of research in the medical fraternity. Additionally, the use of DOI for articles published in the journal started in 2011 (2011, volume 17, Issue 2). In order to facilitate the recognition and access of the articles, DOIs have also been defined for all articles published in previous issues.   Editors Ayşe Balat, MD, became the new Editor-in-Chief of Eur J Ther for the second time, the first between 2007-2010.

ABSTRACT Background Large international differences exist in kidney transplantation (KT) rates. We aimed to investigate which factors may explain the total, deceased donor and living donor KT rates over the last decade. Methods KT experts from 39 European countries completed the Kidney Transplantation Rate Survey on measures and barriers and their potential effect on the KT rate in their country. In the analyses, countries were divided into low, middle and high KT rate countries based on the KT rate at the start of study period in 2010. Results Experts from low KT rate countries reported more frequently that they had taken measures regarding staff, equipment and facilities to increase the total KT rate compared with middle and high KT rate countries. For donor type–specific KT, the largest international differences in measures taken were reported for deceased donor KT, with middle and high KT rate countries taking more measures, such as the use of expanded criteria donor kidneys, the presence of transplantation coordinators and (inter)national exchange of donor kidneys. Once a measure was taken, experts’ opinion on its success was similar across the low, middle and high KT rate countries. Experts from low KT rate countries more often reported potential barriers, such as patients’ lack of knowledge and distrust in the healthcare system. Conclusions Particularly in low KT rate countries, the KT rate might be stimulated by optimizing staff, equipment and facilities. In addition, all countries may benefit from measures specific to deceased and living donors.

ABSTRACT Background The aim of this study was to identify trends in total, deceased donor (DD) and living donor (LD) kidney transplantation (KT) rates in European countries. Methods The European Renal Association (ERA) Registry and the Global Observatory on Donation and Transplantation (GODT) databases were used to obtain the number of KTs in individual European countries between 2010 and 2018. General population counts were obtained from Eurostat or the national bureaus of statistics. The KT rate per million population (p.m.p.) and the average annual percentage change (APC) were calculated. Results The total KT rate in the 40 participating countries increased with 1.9% annually [95% confidence interval (CI) 1.5, 2.2] from 29.6 p.m.p. in 2010 to 34.7 p.m.p. in 2018, reflecting an increase of 3.4 p.m.p. in the DD-KT rate (from 21.6 p.m.p. to 25.0 p.m.p.; APC 1.9%; 95% CI 1.3, 2.4) and of 1.5 p.m.p. in the LD-KT rate (from 8.1 p.m.p. to 9.6 p.m.p.; APC 1.6%; 95% CI 1.0, 2.3). The trends in KT rate varied widely across European countries. An East–West gradient was observed for DD-KT rate, with Western European countries performing more KTs. In addition, most countries performed fewer LD-KTs. In 2018, Spain had the highest DD-KT rate (64.6 p.m.p.) and Turkey the highest LD-KT rate (37.0 p.m.p.). Conclusions The total KT rate increased due to a rise in the KT rate from DDs and to a lesser extent from LDs, with large differences between individual European countries.
