BACKGROUND: No gold standard exists for renal volumetry in vivo. PURPOSE: To devise and evaluate segmentation methods on magnetic resonance imaging (MRI) datasets. MATERIAL AND METHODS: Five combinations of MRI pulse sequences and measuring methods were used to measure the renal volumes of five men aged 54-72 years scanned before autologous renal stem cell transplantation and three, six, and 12 months post transplantation. RESULTS: Renal volume did not change after stem cell transplantation...

Ceftriaxone is a widely used third-generation cephalosporin showing advantageous pharmacokinetic properties and a broad antimicrobial spectrum. We herein report a case of ceftriaxone-induced neurotoxicity in a 56-year-old man on hemodialysis. Seven days after initiating high-dose ceftriaxone, the patient developed impaired consciousness along with facial myoclonus and sporadic phonation. The symptoms clearly disappeared shortly after withdrawal of the drug. Ceftriaxone is considered a safe antibiotic for patients with renal insufficiency, since it is excreted via both haptic and renal pathways...

INTRODUCTION: Now that long term survival after successful renal transplantation is no longer limited by excessive cardiovascular risk, the primary care physician should consider that infection and malignancy are leading non-cardiovascular causes of death even in the recipient with diabetes. METHODS: We accessed the NIH sponsored FAVORIT study population (4010 renal transplant recipients with elevated homocysteine levels) studied to determine whether folate and B12 supplementation would reduce cardiovascular endpoints...

PURPOSE: A growing body of evidence suggest it is safe to ligate the ureter of poorly functioning renal moieties during renal transplantation. Herein, we present clinical outcomes and data on hydronephrosis progression in pediatric cases associated with ectopic ureters and obstructive ureteroceles. MATERIAL AND METHODS: Prospective data collection on 35 consecutive patients (23 female, 12 male) who underwent ureteral clipping between 02/2011 and 08/2016. Patients were divided in four groups [I: duplex system (DS) with ectopic ureter (45...

Cardiovascular disease is the leading cause of death in patients with end-stage renal disease (ESRD) and often goes undetected. Abnormal coronary flow reserve (CFR), which predicts increased risk of cardiac death, may be present in patients with ESRD without other evidence of coronary artery disease (CAD). We prospectively studied 131 patients who had rest and dipyridamole pharmacologic stress N(13)-ammonia positron emission tomography myocardial perfusion imaging (PET MPI) for kidney transplant evaluation...

PURPOSE: The main purposes of the study were to investigate the endocrine function of ovarian tissue transplanted to heterotopic subcutaneous sites and the reproductive competence and telomere length of a nonhuman primate originating from transplanted tissue. METHODS: Ovarian cortex pieces were transplanted into the original rhesus macaques in the arm subcutaneously, in the abdomen next to muscles, or in the kidney. Serum estradiol (E2) and progesterone (P4) concentrations were measured weekly for up to 8 years following tissue transplantation...

A 35-year-old female renal transplant recipient was referred to the metabolic bone clinic because of a 15 cm loss of height. She was noted to have thoracic kyphosis and vertebral X-ray confirmed a wedge fracture of the eighth thoracic vertebra. She was managed accordingly but on subsequent follow-up mentioned in passing that her gynaecologist had been unable to obtain a cervical smear for routine screening. This led to further questioning, and the patient reported intermittent urinary stress incontinence, feelings of vaginal fullness and severe dyspareunia...

Broad T cell depletion by polyclonal anti-thymocyte globulins (ATG) has been used for many years as a part of immunosuppressive treatment in transplantation. Currently, two different ATG are used in clinical practice, Thymoglobulin and Grafalon. Due to differences in the immunization source, these products contain different specificities and quantity of antibodies. These differences may have clinical consequences. We conducted a nested study in a large prospective multicentric cohort of kidney transplant to determine whether Grafalon-treated and Thymoglobulin-treated patients experience different lymphocyte reconstitution and clinical outcomes...

Chikungunya (CHIK) is a mosquito-borne virus (CHIKV) infection that recently appeared in the Americas and thousands of confirmed cases have been reported in Brazil since the first autochthonous cases were reported in September 2014. We reported four cases of CHIK in kidney transplant recipients. The diagnosis was confirmed by positive CHIKV real-time polymerase chain reaction in two cases and positive CHIKV-IgM serology in two patients. The time between transplantation and CHIKV infection ranged from 2 to 11 years...

BACKGROUND: Continuous flow (CF) left ventricular assist devices (LVADs) improve survival in end-stage heart failure patients who are ineligible for cardiac transplantation. Their use in this population (referred to as destination therapy) is increasing in many countries, yet they are not routinely funded for this indication in Canada. We assessed the cost-effectiveness of destination therapy CF-LVADs from the perspective of the Canadian health care payer. METHODS: A Markov model was used to project the outcomes and costs of 2 treatment pathways, CF-LVAD implantation and medical management alone, in an end-stage heart failure patient cohort ineligible for transplantation...

Human herpes virus 8 (HHV-8), also known as Kaposi's sarcoma associated herpesvirus (KSHV), is an oncogenic virus that can cause Kaposi's sarcoma (KS). KS can develop following organ transplantation through reactivation of the recipient's latent HHV-8 infection, or less commonly through donor-derived infection which has higher risk for severe illness and mortality. We describe a case of probable donor-derived KS in the recipient of a liver-kidney transplant. The donor had multiple risk factors for HHV-8 infection...

Fungal arteritis affecting graft arteries is a rare but life-threatening complication in kidney transplantation (KT). Here, we report the case of a patient with Aspergillus arteritis who experienced renal artery rupture 8 days after KT. We also reviewed 50 other reported cases of fungal arteritis after KT. We found that fungal contamination can occur during kidney graft harvest, preservation, and/or transplantation. Typically, early diagnosis, timely antifungal treatment, and emergency surgery seem crucial for avoiding life-threatening vascular complications...

Despite its impact on quality of life and potential for complications, specific risk and protective factors for herpes zoster (HZ) after kidney transplantation (KT) remain to be clarified. We included 444 patients undergoing KT between November 2008 and March 2013. Peripheral blood lymphocyte subpopulations were measured at baseline and months 1 and 6. The risk factors for early (first post-transplant year) and late HZ (years 1 to 5) were separately assessed. We observed 35 episodes of post-transplant HZ after a median follow-up of 48...

Seasonal variation in the incidence and cardiovascular disease complications in the general population has been well documented (1) . According to analysis of data from the United States Renal Data System (USRDS) of all prevalent end-stage kidney disease (ESKD) patients between 2000 and 2013, the transition to ESKD (i.e. initiation of renal replacement therapy) and the incidence of all-cause and cause-specific mortality in patients with ESKD were highest during winter months (particularly January) compared to summer months, suggesting the possibility of season-specific precipitants during winter months contributing to adverse outcomes in both the general population and in patients with ESKD (2) ...

BACKGROUND: Congenital thrombotic thrombocytopenic purpura (TTP) may not be recognized until organ failure related to the microvascular thrombosis occurs. Kidney failure may be the initial presenting clinical feature. Kidney transplantation has been contraindicated because of the assumption that the continuing microvascular thrombosis will cause inevitable graft failure. CASE REPORT: We report a 48-year-old nulliparous woman who presented with end-stage kidney disease that was attributed to hypertension...

INTRODUCTION: Living donation accounts for over one-third of all kidney transplants taking place in the UK. (1) The concept of anonymously donating a kidney to a stranger (non-directed altruistic or unspecified kidney donation (UKD)) remains uncomfortable for some clinicians, principally due to concerns about the motivations and long-term physical and psychological outcomes in this donor group. AIMS: The research programme aims to provide a comprehensive assessment of the unspecified donor programme in the UK...

BACKGROUND: Proteinuria is an indicator of subsequent renal function decline in most nephropathies and early proteinuria has been assumed to be a risk factor of poor kidney transplant outcomes. However, there is no information about the effect of earlier-proteinuria at the first week on short-term graft function after living donor renal transplantation. METHODS: Retrospective cohort study of 439 living donor kidney transplants to analyze the effect of early proteinuria at 7-day post-transplantation on short-term prognosis of living donor renal transplantation...
