Mass disasters are characterized by a disparity between healthcare demand and supply, which hampers complex therapies like kidney transplantation. Considering the scarcity of publications on previous disasters, we reviewed transplantation practice during the recent coronavirus disease 2019 (COVID-19) pandemic, and dwelled upon this experience to guide transplantation strategies in the future pandemic and non-pandemic catastrophes. We strongly suggest continuing transplantation programs during mass disasters, if medical and logistic operational circumstances are appropriate. Postponing transplantations from living donors and referral of urgent cases to safe regions or hospitals are justified. Specific preventative measures in anticipated disasters (such as vaccination programs during pandemics or evacuation in case of hurricanes or wars) may be useful to minimize risks. Immunosuppressive therapies should consider stratifying risk status and avoiding heavy immune suppression in patients with a low probability of therapeutic success. Discharging patients at the earliest convenience is justified during pandemics, whereas delaying discharge is reasonable in other disasters, if infrastructural damage results in unhygienic living environments for the patients. In the outpatient setting, telemedicine is a useful approach to reduce the patient load to hospitals, to minimize the risk of nosocomial transmission in pandemics and the need for transport in destructive disasters. If it comes down to saving as many lives as possible, some ethical principles may vary in function of disaster circumstances, but elementary ethical rules are non-negotiable. Patient education is essential to minimize disaster-related complications and to allow for an efficient use of healthcare resources. [ABSTRACT FROM AUTHOR]

Background In patients admitted to the Intensive Care Unit (ICU), Kidney Replacement Therapy (KRT) is an important risk factor for hypophosphataemia. However, studies addressing the development of hypophosphatemia during prolonged intermittent KRT modalities are lacking. Thus, we evaluated the incidence of hypophosphatemia during Sustained Low-Efficiency Dialysis (SLED) in ICU patients; we also examined the determinants of post-SLED serum phosphate level (s-P) and the relation between s-P and phosphate supplementation and ICU mortality. Methods We conducted a retrospective analysis on a cohort of critically ill patients with severe renal failure and KRT need, who underwent at least three consecutive SLED sessions at 24–72 h time intervals with daily monitoring of s-P concentration. SLED with Regional Citrate Anticoagulation (RCA) was performed with either conventional dialysis machines or continuous-KRT monitors and standard dialysis solutions. When deemed necessary by the attending physician, intravenous phosphate supplementation was provided by sodium glycerophosphate pentahydrate. We used mixed-effect models to examine the determinants of s-P and Cox proportional hazards regression models with time-varying covariates to examine the adjusted relation between s-P, intravenous phosphate supplementation and ICU mortality. Results We included 65 patients [mean age 68 years (SD 10.0); mean Acute Physiology and Chronic Health Evaluation II score 25 (range 9–40)] who underwent 195 SLED sessions. The mean s-P before the start of the first SLED session (baseline s-P) was 5.6 ± 2.1 mg/dL (range 1.5–12.3). Serum phosphate levels at the end of each SLED decreased with increasing age, SLED duration and number of SLED sessions (P  < .05 for all). The frequency of hypophosphatemia increased after the first through the third SLED session (P  = .012). Intravenous phosphate supplementation was scheduled after 12/45 (26.7%) SLED sessions complicated by hypophosphataemia. The overall ICU mortality was 23.1% (15/65). In Cox regression models, after adjusting for potential confounders and for current s-P, intravenous phosphate supplementation was associated with a decrease in ICU mortality [adjusted hazard ratio: 0.24 (95% confidence interval: 0.06 to 0.89; P = 0.033)]. Conclusions Hypophosphatemia is a frequent complication in critically ill patients undergoing SLED with standard dialysis solutions, that worsens with increasing SLED treatment intensity. In patients undergoing daily SLED, phosphate supplementation is strongly associated with reduced ICU mortality. [ABSTRACT FROM AUTHOR]

The 2017 version of the Kidney Disease: Improving Global Outcomes (KDIGO) guidelines is the most recent international framework for the evaluation and care of living kidneys donors. Along with the call for an integrative approach evaluating the long-term end-stage kidney disease risk for the future potential donor, several recommendations are formulated regarding the pre-donation glomerular filtration rate (GFR) adequacy with no or little consideration for the donor candidate's age or for the importance of using reference methods of GFR measurements. Herein, we question the position of the KDIGO guidelines and discuss the rationale and modalities for a more basic, but no less demanding GFR evaluation enabling a more efficient selection of potential kidney donors.

The clinical practice guideline Management of Obesity in Kidney Transplant Candidates and Recipients was developed to guide decision-making in caring for people with end-stage kidney disease (ESKD) living with obesity. The document considers the challenges in defining obesity, weighs interventions for treating obesity in kidney transplant candidates as well as recipients and reflects on the impact of obesity on the likelihood of wait-listing as well as its effect on transplant outcomes. It was designed to inform management decisions related to this topic and provide the backdrop for shared decision-making. This guideline was developed by the European Renal Association's Developing Education Science and Care for Renal Transplantation in European States working group. The group was supplemented with selected methodologists to supervise the project and provide methodological expertise in guideline development throughout the process. The guideline targets any healthcare professional treating or caring for people with ESKD being considered for kidney transplantation or having received a donor kidney. This includes nephrologists, transplant physicians, transplant surgeons, general practitioners, dialysis and transplant nurses. Development of this guideline followed an explicit process of evidence review. Treatment approaches and guideline recommendations are based on systematic reviews of relevant studies and appraisal of the quality of the evidence and the strength of recommendations followed the Grading of Recommendations Assessment, Development and Evaluation approach. Limitations of the evidence are discussed and areas of future research are presented. [ABSTRACT FROM AUTHOR]

Background Existing guidelines on the evaluation and preparation of recipients for kidney transplantation target the entire spectrum of patients with end-stage renal disease. Within the ERA-EDTA Developing Education Science and Care for Renal Transplantation in European States (DESCARTES) Working Group, it was proposed that in a subset of relatively young patients (<40 years) without significant comorbidities (such as diabetes or cardiovascular disease), the work-up for transplantation could be restricted to a small set of tests. Methods Aiming for agreement between transplant centres across Europe, we surveyed the opinion of 80 transplant professionals from 11 European states on the composition of a minimal work-up. Results We show that there is a wide agreement among European experts that the work-up for kidney transplantation of the low-risk candidate, as opposed to the standard risk candidate, could include a limited number of investigations. However, there is some disagreement regarding the small number of diagnostic procedures, which is related to geographical location within Europe and the professional background of respondents. Conclusions Based on the results of the survey, published guidelines and expert meetings by the DESCARTES Working Group, we have formulated a proposal for the work-up of low-risk kidney transplant candidates.

Current proposals for waiting times for a renal transplant after malignant disease may not be appropriate. New data on malignancies in end-stage renal disease and recent diagnostic and therapeutic options should lead us to reconsider our current practice. [ABSTRACT FROM AUTHOR]

Metabolic risk factors of cardiovascular disease such as abnormal glucose regulation, obesity and metabolic syndrome, dyslipidaemia, metabolic bone disease, hyperuricaemia and other less traditional abnormalities are common in both kidney transplant candidates and recipients. In kidney transplant candidates, the presence of these risk factors may impede patient access to transplantation by increasing the risk of developing comorbidities while on the waiting list, prolonging the time to wait-listing and, in some patients, eventually jeopardizing their suitability for kidney transplantation or increasing the risk of severe perioperative complications. In transplant recipients, metabolic risk factors may be associated with increased mortality with a functioning graft and with reduced long-term renal graft survival. Although most transplant recipients have no contraindication to the use of drugs that undergo renal excretion, they may be at risk of drug-to-drug pharmacokinetic interactions with anti-rejection medicines. In this review, we have highlighted the main objectives of evaluating the metabolic abnormalities in transplant candidates and recipients, how this evaluation should be carried out in practice and what currently the most valuable treatment strategies are for modifying the associated risks. We conclude that, for every potential transplant candidate, every effort should be made to control metabolic abnormalities causing arterial calcification, which may impede access to transplantation and impair transplant outcome. In transplant recipients, metabolic abnormalities that result from adverse effects of anti-rejection therapy may be effectively controlled by lifestyle changes and judicious use of drugs for the treatment of abnormal glucose metabolism and dyslipidaemia.

Background Asymptomatic bacteriuria is frequent in kidney transplant recipients (KTRs). However, there is no consensus on diagnosis or management. We conducted a European survey to explore current practice related to the diagnosis and management of asymptomatic bacteriuria in adult KTRs. Methods A panel of experts from the European Renal Association–European Dialysis Transplant Association/Developing Education Science and Care for Renal Transplantation in European States working group and the European Study Group for Infections in Compromised Hosts of the European Society of Clinical Microbiology and Infectious Diseases designed this cross-sectional, questionnaire-based, self-administered survey. Invitations to participate were e-mailed to European physicians involved in the care of KTRs. Results Two hundred and forty-four participants from 138 institutions in 25 countries answered the survey (response rate 30%). Most participants [72% (176/244)] said they always screen for asymptomatic bacteriuria in KTRs. Six per cent (15/240) reported never treating asymptomatic bacteriuria with antibiotics. When antimicrobial treatment was used, 24% of the participants (53/224) said they would start with empirical antibiotics. For an episode of asymptomatic bacteriuria caused by a fully susceptible microorganism and despite no contraindications, a majority of participants (121/223) said they would use a fluoroquinolone (n  = 56), amoxicillin/clavulanic acid (n  = 38) or oral cephalosporins (n  = 27). Conclusions Screening for and treating asymptomatic bacteriuria are common in KTRs despite uncertainties around the benefits and harms. In an era of antimicrobial resistance, further studies are needed to address the diagnosis and management of asymptomatic bacteriuria in these patients. [ABSTRACT FROM AUTHOR]
