OBJECTIVES: Fractures are associated with high morbidity and are a major concern for kidney transplant recipients. No comparative analysis has yet been conducted between countries in the contemporary era to inform future international prevention trials. MATERIALS AND METHODS: Data were obtained from the Hospital Episode Statistics and the Statewide Planning and Research Cooperative databases on all adult kidney transplants performed in England and New York State from 2003 to 2013, respectively, and on posttransplant fracture-related hospitalization from 2003 to 2014...

Here, we present 2 patients who developed central pontine myelinolysis after living-donor liver transplant. Both patients had abnormal sodium level before living-donor liver transplant. Patient 1 presented with severe hyponatremia on admission. After administration of 3% saline, her sodium level during the first 24 hours was kept at 100 mEq/L and then increased to 116 mEq/L during the next 24 hours. The level increased 5.8 mEq/L during the 4- to 5-hour transplant procedure. Patient 2 was admitted to the hospital with an unprovoked seizure...

We report an ABO-incompatible kidney transplant performed on a 69-year-old female patient, whose donor was her 69-year-old husband. The patient received an immunosuppressive protocol using rituximab without splenectomy. Renal biopsy was done on posttransplant day 8 due to poor early graft function, and an isolated v-lesion was found, which responded to steroid pulse therapy and gusperimus hydrochloride administration. Our results indicate that isolated v-lesions can occur in ABO-incompatible kidney transplant recipients receiving rituximab and that this finding should be treated as acute rejection...

OBJECTIVES: Rat models of renal transplant are used to investigate immunologic processes and responses to therapeutic agents before their translation into routine clinical practice. In this study, we have described details of rat surgical anatomy and our experiences with the microvascular surgical technique relevant to renal transplant by employing donor inferior vena cava and aortic conduits. MATERIALS AND METHODS: For this study, 175 rats (151 Lewis and 24 Fisher) were used to establish the Fisher-Lewis rat model of chronic allograft injury at our institution...

OBJECTIVES: Historically, hepatitis C virus genotype 3 infection has not been as hard to treat as genotype 1 using interferon-based therapy. Now, genotype 3 infection can be treated using interferon-free regimes such as the combination of sofosbuvir and daclatasvir, which is a highly successful and reliable therapeutic option before liver transplant. However, real world data are rather limited regarding the use of antivirals (sofosbuvir/daclatasvir) for hepatitis C virus genotype 3 recurrence after liver transplant...

Zi Qin Ng, Bulang He
OBJECTIVES: Chyle leak or chylous ascites remains a rare complication after laparoscopic living-donor nephrectomy. Its cause and management have not been well elucidated in the literature. Thus, the aim of this study was to review the incidence of chyle leak/chylous ascites after laparoscopic living-donor nephrectomy in our institute and in the literature to propose a classification system with its associated treatment strategy. MATERILAS AND METHODS: In this retrospective review of laparoscopic living-donor nephrectomy patients from January 2005 to April 2016, we identified patients with chyle leak/chylous ascites along with the care performed...

The development of aortic aneurysms in post-transplant patients is a rare but potentially lethal problem. De novo aortic aneurysm formation and rapid growth are postulated to result from an imbalance between pro- and anti-inflammatory vascular endothelial factors after transplant. Here, we present a case of de novo thoracic aneurysm formation within 2 months of orthotopic liver transplant. Prompt clinical recognition allowed for successful endovascular repair. Transplant clinicians should be aware of this potentially life-threatening complication and monitor at-risk recipients accordingly...

OBJECTIVES: Recurrent glomerulonephritis can negatively affect kidney allograft survival. However, how primary renal disease affects transplant outcomes in the new era of immunosuppression remains unclear. MATERIALS AND METHODS: We categorized 426 kidney transplant recipients (performed from 1996 to 2007) into 4 disease groups: (1) 99 recipients with biopsy-proven immunologically mediated kidney disease, (2) 40 recipients with urologic disease, (3) 67 recipients with polycystic kidney disease, and (4) 220 recipients with other causes of terminal renal failure/uncertain kidney disease...

OBJECTIVES: Paramyxoviruses contribute to morbidity and mortality after lung transplant and are associated with bronchiolitis obliterans syndrome. Oral ribavirin has been used off-label for treatment of paramyxoviruses in immunosuppressed patients; however, data supporting its use for this purpose are lacking. MATERIALS AND METHODS: We conducted a retrospective review to evaluate clinical outcomes of lung transplant recipients infected with paramyxoviruses and received treatment with oral ribavirin at 2 tertiary referral centers...

OBJECTIVES: Persistent secondary hyperparathyroidism is common after successful kidney transplant, with concomitant hypercalcemia and hypophosphatemia potentially leading to reduced graft survival and increased cardiovascular risk. Cinacalcet, a calcimimetic agent that activates the calcium-sensing receptors in parathyroid glands, is a therapeutic option. In this study, we assessed the long-term treatment effects of cinacalcet for a period of up to 5 years in a cohort of kidney transplant recipients...

OBJECTIVES: Due to widespread exploitation of extended criteria donors, machine perfusion is emerging as an alternative to static cold storage for organ preservation. Hypothermic oxygenated machine perfusion has been associated with improved outcomes after liver transplant, both in laboratory and clinical settings. Here, we present our initial experience with hypothermic oxygenated machine perfusion, evaluating incidence of postreperfusion syndrome, early allograft dysfunction, and long-term biliary complications...

Traumatic external iliac artery dissection after renal transplant is a rare complication, but it should be urgently managed due to its devastating effects on graft and lower limb circulation. External iliac artery dissection is seen more in recipients with diabetes mellitus and comorbid disease. Recipients with external iliac artery dissection should be treated immediately by percutaneus angioplasty or surgical reconstruction. In this study, we reported the management of 2 kidney transplant cases with external iliac artery dissection due to vascular clamping of the artery...

OBJECTIVES: Data on the relevance of surgeon experience in liver transplant procedures are scarce. In this study, we evaluated the effects of individual surgeon experience on survival outcomes after deceased-donor liver transplant. MATERIALS AND METHODS: In this retrospective analysis of 1193 liver transplant procedures, quantile regression for survival data was performed to assess the effects of surgeon experience. Conditional quantiles of mortality and graft loss were set as primary and secondary outcome measures, respectively, which were categorized as early, midterm, and late...

OBJECTIVES: Benign prostate hyperplasia is frequently diagnosed in elderly chronic renal failure patients. Although it is asymptomatic because urine flow declines in those with chronic renal failure, it may become symptomatic when urine flow increases after renal transplant. Untreated benign prostate hyperplasia may lead to several complications that adversely affect the kidney allograft. MATERIALS AND METHODS: Our retrospective study investigated data from 286 male transplant patients...

Generalized lymphadenopathy after organ transplant is a concerning finding, often indicating the devel-opment of lymphoma. We describe a 52-year-old liver transplant recipient who had clinical symptoms and imaging concerning for posttransplant lymphoproliferative disease. However, histologic evaluation of a lymph node biopsy revealed that the patient actually had a much rarer but relatively benign condition, Kikuchi-Fujimoto disease (histiocytic necrotizing lymphadenitis). We discuss the epidemiology, clinical symptoms, diagnosis, histologic features, and treatment of this uncommon mimic of posttransplant lymphoproliferative disease...

OBJECTIVES: How smoking history affects kidney allograft outcomes is unclear in the contemporary era of immunosuppression. Here, we examined a broad range of outcomes after kidney transplant, stratifying patients by smoking status documented at time of transplant, in a well-characterized clinical cohort. MATERIALS AND METHODS: This retrospective single-center analysis (2007-2015) included 744 kidney allograft recipients who had documentation of smoking exposure (median follow-up 1327 days posttransplant)...

OBJECTIVES: Mycophenolate mofetil is a first-line drug after organ transplant, but there are differences in metabolism of mycophenolate mofetil among individuals. The UDP glucuronosyltransferase enzyme is the key metabolic enzyme for mycophenolate mofetil, and UGT1A8 gene polymorphisms may affect the elimination of mycophenolate mofetil in patients. Here, we conducted an in vitro study to explore the relation between UGT1A8 gene polymorphisms and mycophenolate mofetil metabolism. MATERIALS AND METHODS: Five mutant loci overexpression vectors (UGT1A8 128C>T, 157C>A, 431C>T, 518C>G, and 830G>A) were constructed by genetic recombination and site-directed mutagenesis...

OBJECTIVES: Cardiovascular disease is the major cause of morbidity and mortality in patients on renal replacement therapy and in kidney transplant recipients. There are no specific recommendations for preoperative cardiac risk assessment before renal transplant. The aim of our study was to analyze preoperative cardiac test frequencies, test results, patient characteristics, and relations between cardiac stress test results and severe coronary artery disease. MATERIALS AND METHODS: We retrospectively examined patients who underwent renal transplant between December 2011 and December 2016 in our hospital (Ankara, Turkey)...
