We report a case of recurrent renal cancer in the autografted kidney, treated with percutaneous cryoablation. A 59-year-old man who had bilateral renal tumors underwent radical left nephrectomy, ex vivo right partial nephrectomy and auto-transplantation at the right ileal fossa in our hospital 11 years ago. Histopathological examination showed clear cell renal cell carcinoma in bilateral kidneys (pT1bN0M0). He had been followed at another hospital without tumor recurrence for 11 years. In 2014, an enhanced CT scan revealed a renal tumor with a diameter of two centimeters in the autografted kidney, which was thought to be a recurrence of the initial renal cancer...

BACKGROUND: Simple renal cysts may be an early marker of renal disease. We investigated whether simple cysts in donor kidney are associated with the decline of allograft function in living donor kidney transplantation. METHODS: We retrospectively reviewed records of donors and recipients from 716 living donor kidney transplants performed between April 2007 and April 2015 in our hospital. Ninety-one donors with renal cysts and 64 recipients with cysts in donor kidney were noted...

The XIII. Banff meeting, held in conjunction the Canadian Society of Transplantation in Vancouver, Canada, reviewed the clinical impact of updates of C4d-negative antibody-mediated rejection (ABMR) from the 2013 meeting, reports from active Banff Working Groups, the relationships of donor specific antibody tests (anti-HLA and non-HLA) with transplant histopathology, and questions of molecular transplant diagnostics. The use of transcriptome gene sets, their resultant diagnostic classifiers, or common key genes to supplement the diagnosis and classification of rejection, requires further consensus agreement and validation in biopsies...

BACKGROUND: Severe multilayering (ML) of the peritubular capillary basement membranes in kidney allografts is considered to be an ultrastructural hallmark of chronic antibody-mediated rejection (CAMR). We describe here the unexpected findings in a young male adolescent with underlying focal segmental glomerulosclerosis who underwent a living-related donor transplant procedure, a case which brought into question the specificity of ML. METHODS: The patient received a kidney from his mother, whose donor screening was unremarkable...

BACKGROUND: Demand for deceased donor kidneys has exceeded supply in Australia over the past 2 decades. With a desire to use as many donor organs as possible, the health characteristics of accepted donors may have changed over time. METHODS: All deceased kidney donors actually transplanted in Australia between January 1, 1994, and December 31, 2013, were retrospectively analyzed, using data from the Australian and New Zealand Organ Donor Registry. RESULTS: Of 4172 deceased donors, 57% were men...

BACKGROUND: HLA mismatches are the primary cause of alloantibody-mediated rejection (AMR) in organ transplantation. To delineate antigenic and immunogenic potentials among individual HLA mismatches, information regarding antibody specificity at the epitope level, instead of the allelic level, is needed. METHODS: This study explores a direct screening method for HLA linear epitopes in kidney transplant patients. We custom synthesized a large panel of 15-residue HLA peptides in an array format and measured alloantibody reactivity to these peptides from the sera of post and/or pretransplant patients...

Hepatitis viruses are named for their primary clinical illness, inflammation of the liver. Currently, six types of viruses are designated hepatitis viruses (A, B, C, D, E, and G), although only five of these cause hepatitis. Hepatitis viruses are composed of RNA and DNA viruses from different families and with different virologic properties, some of which typically cause acute hepatitis while others cause acute and chronic hepatitis. In addition to their role in liver disease, members of this group of viruses may cause a variety of pathologic changes in the kidney and other organs, and chronic infection may lead to cirrhosis in addition to raising a variety of important issues in the management of kidney transplant recipients...

BACKGROUND: Lymphangiogenesis occurs in diseased native kidneys and kidney allografts, and correlates with histological injury; however, the clinical significance of lymphatic vessels in kidney allografts is unclear. METHODS: This study retrospectively reviewed 63 kidney transplant patients who underwent protocol biopsies. Lymphatic vessels were identified by immunohistochemical staining for podoplanin, and were classified according to their location as perivascular or interstitial lymphatic vessels...

BACKGROUND: Secondary bladder amyloidosis is an extremely rare disease, resulting from a chronic systematic inflammatory disorder associated with amyloid deposits. Although uncommon in Japan, familial Mediterranean fever (FMF) is a hereditary autoinflammatory disease characterized by recurrent episodes of fever of short duration and serositis and is frequently associated with systemic amyloidosis. Here, we present a case of a Japanese patient complaining of fever and macroscopic hematuria after a living donor renal transplantation...

Urine represents a noninvasive source in which proteins and nucleic acids can be assessed. Such analytes may function as biomarkers to monitor kidney graft pathology at every desired frequency, thereby providing a time window to prevent graft damage by therapeutic intervention. Recently, several proteins have been measured in urine as markers of graft injury. However, the specificity is limited, and measuring urinary proteins generally lacks the potential to predict early kidney graft damage. Currently, urinary mRNA and microRNA are being investigated to evaluate the prognostic value of changes in gene expression during the initial stages of graft damage...

Haemolytic uraemic syndrome (HUS) is defined by the simultaneous occurrence of nonimmune haemolytic anaemia, thrombocytopenia and acute renal failure. This leads to the pathological lesion termed thrombotic microangiopathy, which mainly affects the kidney, as well as other organs. HUS is associated with endothelial cell injury and platelet activation, although the underlying cause may differ. Most cases of HUS are associated with gastrointestinal infection with Shiga toxin-producing enterohaemorrhagic Escherichia coli (EHEC) strains...

Mesenchymal stem cells form a population of self-renewing, multipotent cells that can be isolated from several tissues. Multiple preclinical studies have demonstrated that the administration of exogenous MSC could prevent renal injury and could promote renal recovery through a series of complex mechanisms, in particular via immunomodulation of the immune system and release of paracrine factors and microvesicles. Due to their therapeutic potentials, MSC are being evaluated as a possible player in treatment of human kidney disease, and an increasing number of clinical trials to assess the safety, feasibility, and efficacy of MSC-based therapy in various kidney diseases have been proposed...

INTRODUCTION: We present a case report of ectopic pregnancy (EP) after simultaneous pancreas-kidney transplantation (SKPTx). PRESENTATION OF CASE: A 33-year-old female status post SKPTx suddenly got abdominal pain in the lower level. She had high human chorionic Gonadotropin test. Ultrasonography revealed that there was no fetus in the uterus but a dilated right fallopian tube, which strongly suggested ectopic pregnancy. An emergency operation was performed and a dilated right side uterine tube was found with adhesions to her transplant...

Cellular and antibody-mediated rejection processes and also interstitial fibrosis/tubular atrophy (IFTA) lead to allograft dysfunction and loss. The search for accurate, specific and non-invasive diagnostic tools is still ongoing and essential for successful treatment of renal transplanted patients. Molecular markers in blood cells and serum may serve as diagnostic tools but studies with high patient numbers and differential groups are rare. We validated the potential value of several markers on mRNA level in blood cells and serum protein level in 166 samples from kidney transplanted patients under standard immunosuppressive therapy (steroids±mycophenolic acid±calcineurin inhibitor) with stable graft function, urinary tract infection (UTI), IFTA, antibody-mediated rejection (ABMR), and T-cell-mediated rejection (TCMR) applying RT-PCR and ELISA...

Mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes (MELAS syndrome) represents one of the most frequent mitochondrial disorders. The majority of MELAS cases are caused by m.3243A>G mutation in the mitochondrial MT-TL1 gene, which encodes the mitochondrial tRNA(Leu(UUR)). Kidney involvement usually manifests as Fanconi syndrome or focal segmental glomerulosclerosis. We describe a patient with MELAS mutation, cardiomyopathy, and chronic kidney disease without Fanconi syndrome, proteinuria, or hematuria...

This paper reviews the recently published scientific information regarding ANCA-associated vasculitis (AAV), aiming to highlight the most important data from the clinical nephrologists' perspective. The classification, pathomechanism, recent achievements of the treatment, short-term and long-term outcomes of the disease, and the difficulties nephrologists face when taking care for patients with AAV are summarized. There has been significant progress in the understanding of the genetic and pathologic background of the disease in the last years, and results of histological studies guide us to predict long-term renal function...

BACKGROUND: Kidney transplantation (ktx) in mice is used to learn about rejection and to develop new treatment strategies. Past studies have mainly been based on histological or molecular biological methods. Imaging techniques to monitor allograft pathology have rarely been used. METHODS: Here we investigated mice after isogenic and allogenic ktx over time with functional MRI with diffusion-weighted imaging (DWI) and mapping of T2-relaxation time (T2-mapping) to assess graft inflammation and edema formation...
