BACKGROUND: Survival for patients commencing renal replacement therapy is around 90% in the first year and 83% at two years after starting dialysis. The factors that appear to predict mortality are comorbidity and frailty associated with kidney disease, glomerular filtration rate, age and biochemical factors. OBJECTIVES: To analyse the condition of patients starting renal replacement therapy, based on biomarkers commonly used in clinical practice and their association with mortality, measured 6 and 12 months after initiating replacement therapy...

The objective of this review is to explore the available literature on solid renal masses (SRM) in transplant allograft kidneys to better understand the epidemiology and management of these tumors. A literature review using PubMed was performed according to the PRISMA methodology. Fifty-six relevant studies were identified from 1988-2015. A total of 174 SRMs in 163 patients, were identified with a mean tumor size of 2.75 cm (0.5-9.0cm). Tumor histology was available in 164 (94.3%) tumors: clear cell renal cell carcinoma (RCC) (45...

Belatacept, a T cell costimulation-blocker demonstrated superior renal function, lower cardiovascular risk, and improved graft/patient survival in renal transplant recipients. Despite the potential benefits, adoption of belatacept has been limited in part due to concerns regarding higher rates and grades of acute rejection in clinical trials. Since July 2011 we have utilized belatacept-based immunosuppression regimens in clinical practice. In this retrospective analysis of 745 patients undergoing renal transplantation at our center, we compared patients treated with belatacept (n=535) to a historical cohort receiving a tacrolimus-based protocol (n=205)...

BACKGROUND: Dual kidney transplantation (DKT) was developed in order to improve outcomes from transplantation of extended criteria donors (ECD). This paper examined which surgical techniques have been reported for DKT, and whether any technique had superior patient and graft survival. METHOD: Electronic databases were searched for published studies mapping to MESH terms: ''kidney or renal" AND "transplan*" AND "dual or double". Single case reports; studies of patients less than 18 years old; studies which did not describe the surgical technique; and studies that did not report patient or graft survival were excluded...

OBJECTIVE: Renal transplantation (RTx) is considered the treatment of choice for end-stage renal disease (ESRD) given its association with lower mortality, and improved overall quality of life and psychological functioning compared to dialysis. However, much less is known about which factors underlie these psychological improvements across RTx. Goal theory suggests that experienced disturbances in important goals are related to lower psychological functioning. This study aimed to (1) identify the most disturbed and most important goals for patients before RTx, (2) to examine changes in goal disturbance and goal importance pre/post-RTx, and (3) to examine whether changes in goal disturbance are associated with changes in psychological distress over time, and whether this relationship is mediated by changes in perceived control...

Hypogammaglobulinemia is well-characterized as a common phenomenon after kidney transplantation. However, no reports of pre-existing hypogammaglobulinemia from kidney transplantation seem to be available. We have reviewed three patients who developed hypogammaglobulinemia prior to kidney transplantation, and all three were treated successfully with immunoglobulin-replacement therapy before and after kidney transplantation. The kidney grafts were functioning at follow-up 1.5 to 8 years (mean: 3.6 years) after transplantation, and there were no diagnosed episodes of clinical rejections and no severe infection complications post-transplantation...

BACKGROUND: The gut microbiome is the full set of microbes living in the gastrointestinal tract and is emerging as an important dynamic/fluid system that, if altered by environmental, dietetic or pharmacological factors, could considerably influence drug response. However, the immunosuppressive drug-induced modifications of this system are still poorly defined. METHODS: We employed an innovative bioinformatics approach to assess differences in the whole-gut microbial metagenomic profile of 20 renal transplant recipients undergoing maintenance treatment with two different immunosuppressive protocols...

BACKGROUND: Vascular occlusion is a rare, but serious complication after kidney transplantation often resulting in graft loss. We therefore aimed to develop an experimental porcine model for stepwise reduction of the renal venous blood flow and to compare an implantable Doppler probe and microdialysis for fast detection of vascular occlusion. METHODS: In 20 pigs, implantable Doppler probes were placed on the renal artery and vein and a microdialysis catheter was placed in the renal cortex...

The dental follicle (DF), most often associated with unerupted teeth, is a condensation of ectomesenchymal cells that surrounds the tooth germ in early stages of tooth development. In the present study, we aim to isolate epithelial stem-like cells from the human DF and explore their potential differentiation into salivary gland (SG) cells. We demonstrated the expression of stem cell-related genes in the epithelial components of human DF tissues, and these epithelial progenitor cells could be isolated and ex vivo expanded in a reproducible manner...

We present two unusual cases of microvascular thrombosis in the immediate posttransplant period resulting in graft loss. The first was a 20-year-old female with a cadaveric renal transplant with immediate graft dysfunction due to microthrombi of probable donor origin, with nonrecovery of renal function nine months' posttransplant. The second was a 23-year-old male with unrelated live kidney transplant with hyperacute rejection due to anti-endothelial antibodies.

Recurrent focal segmental glomerulosclerosis (FSGS) develops in about 30%-40% of patients of FSGS undergoing renal transplantation. We report a patient who received a live- related renal transplant for end-stage renal disease due to a primary FSGS (not otherwise specified) in the native kidney and presented with graft dysfunction in the immediate posttransplant period. The first and the second biopsy showed no evidence of rejection or glomerular lesion. A repeat biopsy done on the 30th day revealed recurrent FSGS morphologically presenting as collapsing variant...

The newer and potent immunosuppressive agents have successfully reduced the risk of rejection after kidney transplantation, but the development of cardiovascular diseases, infections, and malignancy is major factors limiting their success. Posttransplantation malignancy is the second most common cause of death in renal transplant recipients after cardiovascular disease; it is expected that mortality due to malignancy may become the most common cause of death within the next two decades. This study is designed to evaluate the incidence, risk factors, and types of malignancies occurring after renal transplantation and their impact on patient and graft survival...

Mayer-Rokitansky-Küster-Hauser syndrome is a rare disorder consisting of vaginal aplasia and other müllerian duct abnormalities. Urinary tract malfor-mations possibly leading to renal failure are also common. For these patients, kidney transplant remains the best option. However, aberrant anatomy and scarring from previous operations may actually preclude successful implantation of the graft. In this setting, careful pretransplant evaluation with high-resolution imaging studies and multidisciplinary planning are mandatory...

Verticillium species is a filamentous fungus that inhabits decaying vegetation and soil. It is known to cause disease in plants. Four cases of human infections have been reported previously in nontransplant patients. Here, we report the first case of Verticillium species skin infection in a transplant patient who was successfully treated with fluconazole monotherapy.

BACKGROUND: CYP3A5 genetic polymorphisms have been reported to be strongly associated with the tacrolimus pharmacokinetics in adult kidney transplantation. However, there is no published meta-analysis in the influence of CYP3A5 variants on the requirements of the tacrolimus dose in pediatric renal-transplant recipients (RTRs). We wished to determine the effects of CYP3A5 polymorphisms on tacrolimus pharmacokinetics in pediatric RTRs. METHODS: A literature search was conducted to include relevant articles by searching PubMed, EMBASE and the Cochrane Central Register of Controlled Trials...

BACKGROUND: Calcineurin inhibitor (CNI)-induced nephrotoxicity and chronic graft dysfunction with deteriorating glomerular filtration rate (GFR) are common problems of kidney transplant recipients. The aim of this study was to analyze the role of belatacept as a rescue therapy in these patients. METHODS: In this retrospective, observational study we investigated 20 patients (10 females, 10 males) who were switched from a CNI (tacrolimus) to a belatacept-based immunosuppression because of CNI intolerance or marginal transplant function...

PURPOSE OF REVIEW: BK virus is a significant risk factor for kidney allograft dysfunction and loss among renal transplant recipients. Currently, there is no proven effective treatment except for the reduction of immunosuppression. In this review, we discuss diagnostic challenges and current treatment options for BK in kidney transplant recipients. RECENT FINDINGS: Antiviral and antibiotic therapies have been employed for BK viraemia with variable efficacy. In addition, novel therapeutic regimens such as adoptive transfer of targeted T cells have been described as possible treatment options for recipients with BK nephropathy...
