Induction therapy is a critical component of renal transplantation, aimed at reducing delayed graft function (DGF) and improving graft survival. This review assesses the impact of leading large national and international guidelines: National Institute for Health and Care Excellence (NICE), Kidney Disease: Improving Global Outcomes (KDIGO), and European Renal Best Practice (ERBP) propositions, focusing on their applicability to high-risk groups, specifically, on Black patients and those with donor-specific antibodies (DSAs). While NICE guidelines provide a standardized approach favoring basiliximab, concerns arise regarding their suitability for high-risk patients, who may benefit more from potent lymphocyte-depleting agents.

Chronic kidney disease among liver transplant recipients is common and associated with an increased mortality risk. Several risk factors and causes for the development of chronic kidney disease have been identified. They can be divided into perioperative factors, such as unresolved acute kidney injury; donor-related factors, such as the use of extended criteria liver allografts; and recipient-related factors, such as the use of calcineurin inhibitors and the presence of metabolic syndrome, diabetes, and obesity.

Well-selected patients with kidney disease and diabetes mellitus who undergo simultaneous kidney-pancreas transplantation often experience dramatic improvements in quality of life and long-term survival compared to those who remain on medical therapy. Over the past several years the importance of frailty in the pancreas transplant candidate and recipient populations has grown. More patients with advanced age have entered the waitlist, and complications from prolonged diabetes, even in younger patients, have created increased evidence of risk for frailty.

Article Synopsis
  • Kidney transplant biopsies are crucial for assessing issues with kidney transplants and are performed under ultrasound guidance by either nephrologists or radiologists.
  • A study analyzing 678 biopsies found similar complication rates between the two specialties, with 8% overall complications and no statistically significant difference in outcomes.
  • Factors like blood pressure control and anticoagulation use significantly affected complications and transfusions, but the specialist performing the biopsy did not impact these rates.

Background: Due to a substantial decline in pancreas transplantation (PT) across the United States over the past 15 years, we sought to understand the perceptions and practices of US PT programs.

Methods: Surveys were sent to members of the American Society of Transplantation Surgeons and the American Society of Transplantation by email and professional society postings between August 2019 and November 2019.

Results: One hundred twenty three responses were recorded from 56 unique programs.

Background: The impact of functional status on survival among simultaneous pancreas-kidney transplant (SPKT) candidates and recipients is not well described.

Methods: We examined national Scientific Registry of Transplant Recipients (SRTR) data for patients listed for SPKT in the United States (2006-2019). Functional status was categorized by center-reported Karnofsky Performance Score (KPS).

Bone and mineral disorders are common after organ transplantation. Osteoporosis post transplantation is associated with increased morbidity and mortality. Pathogenesis of bone disorders in this particular sub set of the population is complicated by multiple co-existing factors like preexisting bone disease, Vitamin D deficiency and parathyroid dysfunction.

Objective: Cannabis is the most commonly used recreational drug in the United States, and transplant acceptability for cannabis using candidates varies among transplant centers. However, the prevalence and impact of cannabis use on outcomes of kidney transplant recipients remain unclear. This study aimed to summarize the prevalence and impact of cannabis use on outcomes after kidney transplantation.

Patient monitoring after kidney transplantation (KT) for early detection of allograft rejection remains key in preventing allograft loss. Serum creatinine has poor predictive value to detect ongoing active rejection as its increase is not sensitive, nor specific for acute renal allograft rejection. Diagnosis of acute rejection requires allograft biopsy and histological assessment, which can be logistically challenging in some cases and carries inherent risk for complications related to procedure.

Aim: To assess outcomes of kidney transplantation including patient and allograft outcomes in recipients with hepatitis B virus (HBV) infection, and the trends of patient's outcomes overtime.

Methods: A literature search was conducted using MEDLINE, EMBASE and Cochrane Database from inception through October 2017. Studies that reported odds ratios (OR) of mortality or renal allograft failure after kidney transplantation in patients with HBV [defined as hepatitis B surface antigen (HBsAg) positive] were included.
