Spotted fever rickettsiosis is rarely observed in solid organ transplant recipients, and all previously reported cases have been associated with tick bite months to years after transplantation. We describe a kidney transplant recipient in North Carolina, USA, who had a moderately severe Rickettsia parkeri infection develop during the immediate posttransplant period.

IntroductionChronic kidney disease (CKD) requires patients and caregivers to invest in self-care and self-management of their disease. We aimed to describe the work for adult patients that follows from these investments and develop an understanding of burden of treatment (BoT).MethodsSystematic review of qualitative primary studies that builds on EXPERTS1 Protocol, PROSPERO registration number: CRD42014014547. We included research published in English, Spanish and Portuguese, from 2000 to present, describing experience of illness and healthcare of people with CKD and caregivers. Searches were conducted in MEDLINE, Embase, CINAHL Plus, PsycINFO, Scopus, Scientific Electronic Library Online and Red de Revistas Científicas de América Latina y el Caribe, España y Portugal. Content was analysed with theoretical framework using middle-range theories.ResultsSearches resulted in 260 studies from 30 countries (5115 patients and 1071 carers). Socioeconomic status was central to the experience of CKD, especially in its advanced stages when renal replacement treatment is necessary. Unfunded healthcare was fragmented and of indeterminate duration, with patients often depending on emergency care. Treatment could lead to unemployment, and in turn, to uninsurance or underinsurance. Patients feared catastrophic events because of diminished financial capacity and made strenuous efforts to prevent them. Transportation to and from haemodialysis centre, with variable availability and cost, was a common problem, aggravated for patients in non-urban areas, or with young children, and low resources. Additional work for those uninsured or underinsured included fund-raising. Transplanted patients needed to manage finances and responsibilities in an uncertain context. Information on the disease, treatment options and immunosuppressants side effects was a widespread problem.ConclusionsBeing a person with end-stage kidney disease always implied high burden, time-consuming, invasive and exhausting tasks, impacting on all aspects of patients' and caregivers’ lives. Further research on BoT could inform healthcare professionals and policy makers about factors that shape patients’ trajectories and contribute towards a better illness experience for those living with CKD.PROSPERO registration numberCRD42014014547.

Pediatric organ transplantation, specifically kidney transplant, has improved considerably in recent decades in Iran. Since infections are the most common cause of morbidity and mortality among transplanted children, pre-transplant vaccination is an effective preventive tool in this regard. In addition, administration of some vaccines is contraindicated in post- transplant period and the efficacy and immunogenicity of authorized vaccines may also be suboptimal in comparison to normal population. Therefore, pre-transplant period offers an outstanding chance to boost the immunization of this population. With regard to this population, it is imperative to establish a localized vaccination guideline, which can be used by nephrologists and other clinicians who are part of the transplant team, in Iran. Currently, such a local guideline for Iranian pediatric kidney transplant candidates is not available. The aim of this study is to provide a comprehensive overview of the existing vaccines recommended for these cases regarding the Expanded Program on Immunization (EPI) and available vaccines in Iran. In addition, general principles of vaccination, the use of specific vaccines as well as accelerated vaccination in this population are discussed in this article. This review could be a preliminary guide for preparing a comprehensive guideline for vaccination of this population in Iran.DOI: 10.52547/ijkd.7660

Kidney function continued to improve with plasma creatinine values around 106 μmol/L (53–115 μmol/L). [...]we performed on day 24 a subtotal parathyroidectomy by resecting in toto the two parathyroid hyperplastic foci and the left superior parathyroid gland, together with a partial resection of the right inferior one. [...]patients treated with high-dose of etelcalcetide require close monitoring of calcium levels after transplantation. Conflict of interest The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest. 1.

The best treatment for patients with end-stage kidney disease is kidney transplantation, which, if successful provides both a reduction in mortality and a better quality of life compared to dialysis. Although there has been significant improvement in short-term outcomes after kidney transplantation, long-term graft survival still remains insufficient. As a result, there has been an increase in the number of individuals who need dialysis again after kidney transplant failure, and increasingly contribute to kidney transplant waiting lists. Starting dialysis after graft failure is a difficult task not only for the patients, but also for the nephrologists and the care team. Furthermore, recommendations for management of dialysis after kidney graft loss are lacking. Aim of this narrative review is to provide a perspective on the role of dialysis in the management of patients with failed kidney allograft. Although numerous studies have reported higher mortality in patients undergoing dialysis following kidney allograft failure, reports are contrasting. A patient-centered, individualized approach should drive the choices of initiating dialysis, dialysis modality, maintenance of immunosuppressive drugs and vascular access. Graphical abstract

Tickborne infections are challenging to diagnose, particularly among solid organ transplant recipients. We report a US case of donor-derived ehrlichiosis from a living kidney donation that highlights how screening for living donors may miss tickborne infections. Clinicians should consider the epidemiology of the donor when screening donations and evaluating recipients for donor-derived infection.

Creatine is a natural nitrogenous organic acid that is integral to energy metabolism and crucial for proper cell functioning. The kidneys are involved in the first step of creatine production. With kidney transplantation being the gold-standard treatment for end-stage kidney disease, kidney transplant recipients (KTR) may be at risk of impaired creatine synthesis. We aimed to compare creatine homeostasis between KTR and controls. Plasma and urine concentrations of arginine, glycine, guanidinoacetate, creatine and creatinine were measured in 553 KTR and 168 healthy controls. Creatine intake was assessed using food frequency questionnaires. Iothalamate-measured GFR data were available in subsets of 157 KTR and 167 controls. KTR and controls had comparable body weight, height and creatine intake (all P > 0.05). However, the total creatine pool was 14% lower in KTR as compared to controls (651 ± 178 vs. 753 ± 239 mmol, P < 0.001). The endogenous creatine synthesis rate was 22% lower in KTR as compared to controls (7.8 ± 3.0 vs. 10.0 ± 4.1 mmol per day, P < 0.001). Despite lower GFR, the plasma guanidinoacetate and creatine concentrations were 21% and 41% lower in KTR as compared to controls (both P < 0.001). Urinary excretion of guanidinoacetate and creatine were 66% and 59% lower in KTR as compared to controls (both P < 0.001). In KTR, but not in controls, a higher measured GFR was associated with a higher endogenous creatine synthesis rate (std. beta: 0.21, 95% CI: 0.08; 0.33; P = 0.002), as well as a higher total creatine pool (std. beta: 0.22, 95% CI: 0.11; 0.33; P < 0.001). These associations were fully mediated (93% and 95%; P < 0.001) by urinary guanidinoacetate excretion which is consistent with production of the creatine precursor guanidinoacetate as rate-limiting factor. Our findings highlight that KTR have a disturbed creatine homeostasis as compared to controls. Given the direct relationship of measured GFR with endogenous creatine synthesis rate and the total creatine pool, creatine supplementation might be beneficial in KTR with low kidney function.Trial registration ID: NCT02811835.Trial registration URL: https://clinicaltrials.gov/ct2/show/NCT02811835.

BK virus maintains a latent infection that is ubiquitous in humans. It has a propensity for reactivation in the setting of a dysfunctional cellular immune response and is frequently encountered in kidney transplant recipients. Screening for the virus has been effective in preventing progression to nephropathy and graft loss. However, it can be a diagnostic and therapeutic challenge. In this in-depth state-of-the-art review, we will discuss the history of the virus, virology, epidemiology, cellular response, pathogenesis, methods of screening and diagnosis, evidence-based treatment strategies, and upcoming therapeutics, along with the issue of re-transplantation in patients.

This study aims to identify causal mediators of one-year kidney transplant failure in patients with peripheral vascular disease. Standard Transplant Analysis and Research database was queried for adults who underwent kidney transplantation from 1987 to 2021. Multi-organ transplant, prior transplant, and living donor kidneys were excluded. Causal mediation analysis with 2000 percentile bootstrapping interactions identified mediators of one-year kidney transplant failure. 212,259 patients were included: 16,215 with and 196,044 without peripheral vascular disease. Causal mediators of one-year kidney transplant failure are Kidney Donor Profile Index (proportionate mediation [PM] 17 ​%, p ​< ​0.01, E-value ​= ​1.20), pre-transplant dialysis (PM 19 ​%, p ​< ​0.001, E-value ​= ​1.17), recipient total serum albumin (PM 2 ​%, p ​= ​0.003, E-value ​= ​1.05), and donor hypertension (PM 1 ​%, p ​= ​0.017, E-value ​= ​1.04). Several causal mediators increase rates of one-year kidney transplant failure in patients with peripheral vascular disease. Understanding these mediators can improve pre-transplant assessments and post-transplant outcomes. •PVD is a known significant risk factor for kidney transplant graft failure.•Pre-transplant dialysis and high KDPI mediate this increased graft failure risk.•Mediation findings aid in better patient care and organ allocation strategies.

Successful kidney transplantation offers patients with end-stage renal disease the greatest likelihood of survival. However, cardiovascular disease poses a major threat to both graft and patient survival in this cohort. Transplant recipients are unique in their accumulation of a wide range of traditional and non-traditional cardiovascular risk factors. Hypertension, diabetes, dyslipidaemia and obesity are highly prevalent in patients with end-stage renal disease. These risk factors persist following transplantation and are often exacerbated by the drugs used for immunosuppression in organ transplantation. Additional transplant-specific factors such as poor graft function and proteinuria are also associated with increased cardiovascular risk. However, these transplant-related factors remain unaccounted for in current cardiovascular risk prediction models, making it challenging to identify transplant recipients with highest risk. With few interventional trials in this area specific to transplant recipients, strategies to reduce cardiovascular risk are largely extrapolated from other populations. Aggressive management of traditional cardiovascular risk factors remains the cornerstone of prevention, though there is also a potential role for selecting immunosuppression regimens to minimise additional cardiovascular injury.
