Diabetic kidney disease is the major cause of end-stage kidney disease in developed countries. However, the onset of kidney disorder and the progression pattern of kidney dysfunction and proteinuria greatly vary cases by cases. Therefore, risk classification with clinical data and pathological findings is important. Recent clinico-pathological study with kidney biopsy samples from diabetic patients revealed that pathological changes of diabetic nephropathy are characteristic and have special impacts on prognosis in each clinical stage...

BACKGROUND: IgA-dominant infection-related glomerulonephritis (IgA-IRGN) is a unique form of IRGN, which needs to be distinguished from IgA nephropathy (IgAN). METHODS: Thirteen patients with IgA-IRGN (IgA-IRGN group) and 122 with IgAN (IgAN group) were selected from 1788 patients who underwent kidney biopsy between 2000 and 2015 in Kitano Hospital. Data selected included clinical and serological parameters; light and electron microscope findings; immunofluorescence findings; and prognostic parameters like renal and overall survival and creatinine increase by > 50%...

Merkel cell carcinoma is a primary neuroendocrine tumour of the skin arising from the dermis and extending into the subcutis, occurring commonly in sun-exposed areas of the head and neck of the elderly. Clinically, non-specific erythematous or violaceous firm nodules or small plaques which may be surrounded by small adjacent satellite tumours are seen. Diagnosis of Merkel cell carcinoma is difficult by light microscopy alone and need of ancillary techniques like electron microscopy and immunohistochemistry may be necessary...

Occasionally, renal cell carcinoma (RCC) with renal vein extension spreads against the flow of blood within vein branches into the kidney, forming multifocal nodules throughout the renal parenchyma. These foci are not regarded as multiple tumors but rather reverse spread of tumor along the venous system. This intravascular spread has previously been reported in clear cell RCC and RCC unclassified. However, to our knowledge, this has never been reported in chromophobe RCC. Chromophobe RCC is a unique histologic subtype of renal cancer, generally thought to have less aggressive behavior...

Recognizing the antiphospholipid syndrome (APS) in patients with lupus (SLE) can be difficult and therefore underestimated. Detection of antiphospholipid antibodies (aPL) in each patient with SLE should be done as a rule. Introduction of the new classification criteria of this syndrome will certainly improve the recognition of APS in the future. The Sapporo APS classification criteria (1998) were replaced by the Sydney criteria in 2006. Based on the most recent criteria, classification with APS requires one clinical and one laboratory manifestation...

Background and aims: Dysfunction of a kidney transplant often requires histological sampling by percutaneous ultrasound-guided core needle biopsy. Transplant biopsy is more specialized than native kidney biopsy, the indications and complications are less well defined and in England are performed mainly by nephrologists. The aims of the study were to evaluate the adequacy and complication rate in living and deceased donor recipients according to training status of the nephrologist, assess the accuracy of physicians in predicting rejection, the threshold creatinine rise for biopsy, and the change in drug management post-biopsy...

The impact of CYP3A5 polymorphisms on clinical outcomes is controversial. The present study investigated the impact of CYP3A5 genetic differences on the development of interstitial fibrosis (IF) from 0 h to 1 year post-transplantation in biopsy sections from 96 living kidney recipients under the same target trough regimen of tacrolimus. The relationships between CYP3A5 polymorphisms and long-term graft function and death-censored graft survival were also examined. A quantitative analysis of IF was performed using computer-assisted imaging on virtual slides...

Tumour lysis syndrome (TLS) is a rare oncological emergency in solid tumours. Because it is associated with bad short-term prognosis, early recognition and treatment are mandatory. This case refers to a middle-aged woman who presented with stage IV colon cancer, with massive hepatic involvement. After three cycles of first-line FOLFOX (folinic acid, 5-fluorouracil and oxaliplatin), she developed acute kidney injury and hyperkalaemia that did not respond to standard measures. High suspicion of TLS prompted further corroborating investigations and early intensive care unit admission...

Ischemia-reperfusion injury increases allograft immunogenicity and enhances myeloid dendritic cell maturation and trafficking to recipient's secondary lymphoid tissue. Here, we used postreperfusion biopsies from patients who received kidney allografts from deceased donors between 2006 and 2009 to assess the impact of ischemia-reperfusion damage and myeloid dendritic cell density on subsequent allograft rejection episodes. Histologic changes of severe ischemia-reperfusion damage in postreperfusion biopsies were found to be associated with subsequent rejection episodes and suboptimal allograft survival...

INTRODUCTION: Kidney biopsies are an essential tool in the diagnosis and management of kidney diseases, particularly in kidney transplant recipients. Biopsies carry a risk for serious complications and not all biopsies achieve adequate tissue. We examined the impact of kidney biopsy technique on complications and biopsy adequacy. METHODS: The cohort consisted of consecutive kidney transplant patients undergoing biopsy by one of three techniques: ultrasound localization, real-time ultrasound guidance, and ultrasound-guided trocar placement...

Although gastric metastases have been estimated to occur in less than 2% of cancer patients, an increased use of upper digestive tract endoscopy allows for a higher detection of secondary gastric tumors. We describe the case of a 66-year-old male patient presenting with mild pain in the sternum and upper abdominal area. Physical examination revealed a right parietal skull tumor, with no other significant clinical changes. Upon exclusion of an acute coronary syndrome, upper digestive tract endoscopy was performed, showing the presence of an ulcerated tumor located in the gastric fundus...

BACKGROUND: The classical approach to the analysis of kidney biopsies is based on semi-quantitative scores of the amount of sclerosis, inflammatory infiltrate, fibrosis and vascular damage. However, advanced renal lesions may be accompanied by a paucity of clinical features and, conversely, important clinical abnormalities may be accompanied by minimal histopathological changes. The objective of this study is to correlate new, semiautomatic, quantitative features of kidney biopsies (e...

BACKGROUND: Both prevention and treatment of recurrent immunoglobulin A nephropathy (IgAN) in kidney transplant recipients are important since recurrent IgAN seems to affect long-term graft survival. We present here a case of recurrent IgAN that was successfully treated using steroid pulse therapy plus tonsillectomy 10 years after kidney transplantation. CASE PRESENTATION: A 46-year-old male was admitted for an episode biopsy with a serum creatinine level of 1...

BACKGROUND: Renal fibrosis is a common outcome of nearly all kinds of chronic kidney disease (CKD) and eventually progresses to end-stage renal disease. The identification of an optimal biomarker of renal fibrosis to replace the invasive renal biopsy will have important clinical implications. METHODS: We isolated urinary exosomes from 50 participants and examined the exosomal protein content and particle number in 38 CKD patients with different degrees of renal fibrosis and in 12 normal individuals...

Acute kidney injury (AKI) is a significant cause of morbidity and mortality. Acute tubular injury is considered to be the early pathologic manifestation of AKI, however, the underlying pathology is complex, lacks standards for interpretation, and its relationship with AKI often is unclear or inconsistent. To clarify clinicopathologic correlations in AKI, we evaluated 32 histologic findings in 100 kidney biopsies from patients with AKI as a training set to correlate pathologic findings with clinical AKI grades...

Background: Enteric hyperoxaluria due to malabsorption may cause chronic oxalate nephropathy and lead to end-stage renal disease. Kidney transplantation is challenging given the risk of recurrent calcium-oxalate deposition and nephrolithiasis. Methods: We established a protocol to reduce plasma oxalic acid levels peritransplantation based on reduced intake and increased removal of oxalate. The outcomes of 10 kidney transplantation patients using this protocol are reported...

Background: There is limited information on treatment strategies and monitoring strategies for late antibody-mediated rejection (ABMR) after kidney transplantation. Methods: In this observational and nonrandomized study, we compared 78 patients diagnosed with late ABMR (>3 months after transplant) who were treated with standard of care steroids/IVIG (n = 38) ± rituximab (n = 40) at our center between March 1, 2013 and December 31, 2016. All patients had follow-up biopsy and donor-specific antibodies (DSA) monitoring within 3 to 12 weeks...

BACKGROUND: Glomeruli are excellent pre-determined natural structures for laser micro-dissection. Compartment-specific glomerular gene expression analysis of formalin-fixed paraffin-embedded renal biopsies could improve research applications. The major challenge for such studies is to obtain good-quality RNA from small amounts of starting material, as applicable for the analysis of glomerular compartments. In this work, we provide data and recommendations for an optimized workflow of glomerular mRNA analysis...

BACKGROUND: Page kidney phenomenon is caused by strong renal parenchymal compression and leads to renal hypoperfusion and microvascular ischemia, resulting in renal dysfunction and hypertension. Although the development of Page kidney phenomenon in allograft is rare, most of its cases are induced by allograft biopsy or trauma. We observed a case of Page kidney phenomenon that was induced by unusual causes immediately after kidney transplantation. CASE PRESENTATION: A 66-year-old man, whose wife donated a kidney, underwent ABO-compatible living kidney transplantation...

Transplant is the optimal therapy for patients with end-stage renal disease. Acute cellular rejection refractory to treatment remains a major risk factor for graft loss and poor outcomes. In this study, we describe a 39-year-old man who received a living-related kidney transplant. Two days after transplant, the patient displayed acute deterioration of graft function. Conventional anti-rejection therapy was initiated, but graft function did not improve. Biopsy revealed acute cellular rejection (grade IIA), and C4d and HLA antibodies were negative...
