AIM: To evaluate and compare the outcomes of kidney transplant (KT) from deceased donors among standard criteria, acute kidney injury (AKI) and expanded criteria donors (ECDs). METHODS: This retrospective study included 111 deceased donor kidney transplant recipients (DDKT). Deceased donors were classified as standard criteria donor (SCD), AKI donor and ECD. AKI was diagnosed and classified based on change of serum Cr by acute kidney injury network (AKIN) criteria...

BACKGROUND: After kidney transplantation, fibroblast growth factor-23 (FGF-23) normally returns to baseline within 1 year whereas hyperparathyroidism persists in most kidney transplant (KT) recipients. As a result, serum phosphate remains relatively low in association with increased serum calcium and urinary phosphate excretion when compared to chronic kidney disease patients. The relationship between mineral metabolism and outcomes in long-term KT recipients has not been extensively studied...

: Patients with chronic kidney disease (CKD) are characterized by a state of inflammation and oxidative stress that seems to improve after kidney transplantation (KT). Nevertheless, there is controversy regarding what is the best marker that better define inflammation and specially oxidative stress. OBJECTIVE: To evaluate the biomarkers which are associated with improvements in inflammation and lipid peroxidation in patients who have undergone KT. To evaluate the relationship between inflammation, lipid peroxidation and mortality in KT...

BACKGROUND: As more patients achieve long-term survival, it has become important to understand mortality in LT recipients. METHODS: We conducted retrospective reviews of long-term outcome in two adult LT cohorts: 85,031 in the UNOS database and 1,458 transplanted at the University of Wisconsin (UW). RESULTS: During median follow-up of 3.2 years (UNOS); and 6.6 years (UW), 35.1% of UNOS patients and 44.2% of UW patients died. 43.1% of all UNOS deaths occurred in year one compared to 25...

Metabolic acidosis (MA), indicated by low serum total CO2 (TCO2) concentration, is a risk factor for mortality and progressive renal dysfunction in CKD. However, the long-term effects of MA on kidney transplant recipients (KTRs) are unclear. We conducted a multicenter retrospective cohort study of 2318 adult KTRs, from January 1, 1997 to March 31, 2015, to evaluate the prevalence of MA and the relationships between TCO2 concentration and clinical outcomes. The prevalence of low TCO2 concentration (<22 mmol/L) began to increase in KTRs with eGFR<60 ml/min per 1...

JC polyomavirus-associated nephropathy (JC-PVAN) is a rare but challenging cause of renal dysfunction. We report JC-PVAN in a renal allograft recipient and highlight the obstacles in definitive diagnosis of this disease entity. A deceased-donor renal transplant recipient was diagnosed with JC polyomavirus nephritis 4 years after transplantation. Immunosuppressive agents were subsequently reduced, resulting in an initial stabilization of renal function. We present this interesting case and discuss the challenges with diagnosing and treating this rare entity...

BACKGROUND: Antibody-mediated rejection (ABMR) is a major risk for renal allograft survival. Throughout decades, cyclophosphamide treatment has been proven to be effective in patients with antibody-associated autoimmune diseases. We investigated, whether cyclophosphamide combined with plasmapheresis (PPH) and intravenous immunoglobulins (IVIG) is an option for patients with ABMR. METHODS: Between March 2013 and November 2015, we initiated treatment of 13 consecutive patients with biopsy-proven acute ABMR with i...

Based on native CT scans of the pelvic region using a standardized calcification score, evaluation of iliac vascular calcification was performed between 2008 and 2012 prior to listing for renal transplantation in 205 patients with chronic kidney disease. Vascular calcification showed a decrease from proximal to distal. The difference between the degree of calcification in the common iliac artery and in the external iliac artery was significant (p<0.001). Risk factors for total iliac vascular calcification were age, smoking, sex, underlying renal disease, and diabetes...

BACKGROUND: Following kidney transplantation, early readmission is independently associated with graft loss and mortality. The mechanism of this association is poorly understood. Understanding the timeline of risk, ie, during the readmission hospitalization versus time periods postreadmission, will provide additional insights. METHODS: We used national registry data to study 56,076 adult Medicare-primary first-time kidney transplant recipients from December 1999-October 2011...

Smoking is associated with unfavourable outcome in solid organ transplant recipients. Nicotine may predispose to kidney injury by increasing oxidative stress. We hypothesized that former smoking negatively affects graft outcome in kidney transplant recipients and especially those with delayed graft function (DGF). We included adult recipients of a kidney transplant between January 1(st) 2003 and October 1(st) 2015 at Ghent University Hospital and recorded outcomes until October, 31(st) 2015. We used Kaplan-Meier and multivariable Cox proportional hazard analysis to examine the relationship between former smoking at the time of transplantation and the incidence of 10-year graft loss with and without censoring for death in 1013 participants...

BACKGROUND: Acute kidney injury (AKI) is one of the major determinants of graft survival in kidney transplantation (KTx). Renal Transplant recipients are more vulnerable to develop AKI than general population. AKI in the transplant recipient differs from community acquired, in terms of risk factors, etiology and outcome. Our aim was to study the incidence, risk factors, etiology, outcome and the impact of AKI on graft survival. METHODS: A retrospective analysis of 219 renal transplant recipients (both live and deceased donor) was done...

Equations to estimate glomerular filtration rate (eGFR) were developed in patients using the variables age, body weight, and serum creatinine, which may be different in the elderly. Elderly renal transplant patients (EG; n=70; mean age 65 ± 4 y) who measured plasma (51) Cr-EDTA-Clearance (mGFR) had mGFR compared to eGFR obtained by the Cockcroft-Gault corrected by body surface area (CG-BSA), the modification of diet in renal disease (MDRD-4), the Berlin Initiative Study (BIS-1), and the chronic kidney disease epidemiology collaboration (CKD-EPI)...

In renal transplantation, use of calcineurin inhibitors (CNIs) is associated with nephrotoxicity and immunosuppression with malignancies and infections. This trial aimed to minimize CNI exposure and total immunosuppression while maintaining efficacy. We performed a randomized controlled, open-label multicenter trial with early cyclosporine A (CsA) elimination. Patients started with basiliximab, prednisolone (P), mycophenolate sodium (MPS), and CsA. At 6 months, immunosuppression was tapered to P/CsA, P/MPS, or P/everolimus (EVL)...

BACKGROUND: Concerns exist over the extrapolation of bioavailability studies of generic immunosuppressive drugs in healthy volunteers, regarding their efficacy and safety in kidney transplant recipients. We conducted a meta-analysis of trials examining the bioavailability of generic (test) immunosuppressive drugs relative to their brand (reference) counterparts in healthy volunteers, based on the US Food and Drug Administration requirements for approval of generics, and their efficacy and safety in kidney transplant recipients...

Anemia, iron deficiency anemia (IDA), and iron deficiency (ID) are highly prevalent in renal transplant recipients (RTR). Anemia is associated with poor outcome, but the role of ID is unknown. Therefore, we aimed to investigate the association of ID, irrespective of anemia, with all-cause mortality in RTR. Cox regression analyses were used to investigate prospective associations. In 700 RTR, prevalences of anemia, IDA, and ID were 34%, 13%, and 30%, respectively. During follow-up for 3.1 (2.7-3.9) years, 81 (12%) RTR died...

BACKGROUND: The impact of renal function recovery on graft survival was examined using estimated glomerular filtration rate (eGFR) slope after kidney transplantation (GAP classification); this was compared to the conventional classification of immediate graft function (IGF), slow graft function (SGF), and delayed graft function (DGF). MATERIALS AND METHODS: Overall, 541 cases of cadaveric renal transplants were reviewed from a prospective transplant database. eGFR and its slope were measured using the harmonic mean over the first week post-transplantation...

INTRODUCTION: The aim of this study was to investigate risk factors for urinary tract infections (UTI), the causative organisms of UTI and also their management and treatment. In addition, we evaluated the effects of UTI on renal graft function. METHODS: This analysis included 107 kidney transplant recipients (64% women) with a diagnosis of UTIs confirmed by positive results on urine culture. Type of pathogens, sensitivity to drugs, risk factors for infection, incidence of urosepsis, hospitalization period, treatment methods, and recurrence rates were analyzed...

INTRODUCTION: A patient who complies with doctor recommendations is an indicator of proper cooperation in treatment. It is affected by environmental factors, soft competences of the doctors, and properties of the human personality. We investigated the psychological characteristics of patients that may facilitate human contact and promote healthy behaviors. The aim of the study was to analyze the importance of psychological factors for the occurrence of health-related behaviors necessary for cooperation in treatment...
