A 5-year-old severely growth-retarded child with tubulointerstitial, oliguric end-stage renal disease received an adult-size kidney transplant. Three years post grafting under standard triple immunosuppression (mycophenolate mofetil, tacrolimus, and prednisone) de novo nephrotic range proteinuria without the nephrotic syndrome developed. Graft function was normal (serum creatinine: 0.2 - 0.3 mg/dL), there were no donor-specific HLA antibodies (DSA), and the urine sediment was inactive. Two biopsies collected 3 and 4 years post-transplantation showed severe glomerular capillary wall remodeling and associated pseudolinear C4d staining as morphologic correlates for the proteinuria...

A 37-year-old Japanese man with a serum creatinine level of 2.5 mg/dL and hepatomegaly was admitted to our hospital for investigation of renal failure. Magnetic resonance imaging (MRI) showed hepatomegaly with small cystic lesions that had high signal intensity on T2-weighted images. There was no splenomegaly, and the kidneys were nearly normal in size with a few small cystic lesions. Renal biopsy revealed that interstitial fibrosis and tubular atrophy affected 60% of the cortex. There was cystic tubular dilation, mainly affecting the distal loop of Henle and distal tubules, since immunohistochemical staining of the dilated tubules was positive for cytokeratin 7 and Tamm-Horsfall protein but was negative for aquaporin 3 and CD10...

The kidney is the third most common abdominal organ to be injured in trauma, following the spleen and liver, respectively. The most commonly used classification scheme is the American Association for the Surgery of Trauma (AAST) classification of blunt renal injuries, which grades renal injury according to the size of laceration and its proximity to the renal hilum. Arteriovenous fistula and pseudoaneurysm are the most common iatrogenic biopsy-related or surgery-related vascular injuries in native kidneys. The approach to renal artery injuries has changed over time from more aggressive intervention to more conservative observational or endovascular management, including selective transcatheter arterial embolization (TAE) and the placement of stents/stent grafts...

BACKGROUND The recovery of discarded human kidneys has increased in recent years and impels to use of unconventional organ preservation strategies that improve graft function. We report the first case of human kidneys histologically discarded and transplanted after hypothermic oxygenated perfusion (HOPE). CASE REPORT Marginal kidneys from a 78-year-old woman with brain death were declined by Italian transplant centers due to biopsy score (right kidney: 6; left kidney: 7). We recovered and preserved both kidneys through HOPE and we revaluated their use for transplantation by means of perfusion parameters...

Angiotensin II type 1 receptor (AT1R) antibody has been linked to poor allograft outcomes in adult kidney transplantation. However, its clinical consequences in children are unknown. To study this, we examined the relationship of AT1R antibody with clinical outcomes, biopsy findings, inflammatory cytokines, and HLA donor-specific antibodies (DSA) in a cohort of pediatric renal transplant recipients. Sixty-five patients were longitudinally monitored for AT1R antibody, HLA DSA, IL-8, TNF-α, IL-1β, IFN-γ, IL-17, and IL-6, renal dysfunction, hypertension, rejection, and allograft loss during the first two years post transplantation...

Background: Hyperuricemia (HU) may enhance susceptibility to hypertensive renal damage via disrupted autoregulation of glomerular hemodynamics. The effect of HU on the association between blood pressure (BP) and proteinuria remains unknown in patients with chronic kidney disease (CKD). Methods: In total, 109 patients with non-nephrotic CKD (55 men and 54 females) who underwent renal biopsy were recruited. Arteriolar hyalinosis was semiquantitatively assessed via arteriole grading...

Background: Mitochondrial disorders can present as kidney disease in children and be difficult to diagnose. Measurement of mitochondrial function in kidney tissue may help diagnosis. This study was to assess the feasibility of obtaining renal samples and analysing them for respiratory chain enzyme activity. Methods: The subjects were children undergoing a routine diagnostic renal biopsy, in whom a clinical condition of renal inflammation, scarring and primary metabolic disorder was unlikely. A fresh sample of kidney was snap frozen and later assayed for the activities of respiratory chain enzyme complexes I, II/III, and IV using spectrophotometric enzyme assay, and expressed as a ratio of citrate synthase activity...

BACKGROUND: Adverse events due to conventional immunosuppressive therapy decrease both graft and patient survival. We aimed to establish a new protocol using everolimus (EVR) to safely minimize conventional immunosuppressants in maintenance kidney transplant recipients. METHODS: A total of 86 consecutive kidney transplant recipients with no complications were maintained with triple-drug combination therapy (conventional group). In case of complications, the administration of very low-dose tacrolimus (C0: 5...

We studied the causes and predictors of death-censored kidney allograft failure among 1670 kidney recipients transplanted at our center in the corticosteroid-free maintenance immunosuppression era. As of January 1, 2012, we identified 137 recipients with allograft failure; 130 of them (cases) were matched 1-1 for recipient age, calendar year of transplant and donor type with 130 recipients with functioning grafts (controls). Median time to allograft failure was 29 months (interquartile range 18-51). Physician validated and biopsy confirmed categories of allograft failure were: acute rejection (21%), glomerular disease (19%), transplant glomerulopathy (13%), interstitial fibrosis tubular atrophy (10%), and polyomavirus-associated nephropathy (7%)...

Immunoglobulin G4 (IgG4)-related disease is an uncommon autoimmune disease that affects multiple organ systems. Renal involvement typically presents as tubulointerstitial nephritis and less commonly as membranous glomerulonephritis. In this case report, we discuss a 68-year-old patient who presented with rapidly progressive glomerulonephritis. His renal biopsy revealed a membranoproliferative pattern of injury with fibrocellular crescents and extensive infiltration of the tubulointerstitium with IgG4-positive plasma cells...

BACKGROUND: Nonalcoholic steatohepatitis (NASH) is an active form of nonalcoholic fatty liver disease. Risk factors for NASH include type 2 diabetes mellitus (T2DM) and obesity. Sodium-glucose cotransporter 2 (SGLT2) inhibitors used to treat T2DM prevent glucose reabsorption in the kidney and increase glucose urinary excretion. Dapagliflozin is a potent, selective SGLT2 inhibitor that reduces hyperglycemia in patients with T2DM and has been demonstrated to reduce some complications associated with NASH in rodent models...

BACKGROUND: Immune responses to tissue-restricted self-antigens are thought to play a role in chronic rejection after solid organ transplantation. De novo development of antibodies (Abs) to vimentin have been reported to be associated with interstitial fibrosis/tubular atrophy after kidney transplant, and it has been suggested that immunoglobulin isotype switching of Abs to vimentin may occur during this process. We aimed to determine the correlation between immunoglobulin isotype switching of Abs to vimentin and development of transplant glomerulopathy (TG) after kidney transplant, and to determine whether citrullinated modification of vimentin is required for de novo anti-vimentin development...

Extracellular vesicles (EVs) represent a heterogeneous population of small vesicles, consisting of a phospholipidic bilayer surrounding a soluble interior cargo. Almost all cell types release EVs, thus they are naturally present in all body fluids. Among the several potential applications, EVs could be used as drug delivery vehicles in disease treatment, in immune therapy because of their immunomodulatory properties and in regenerative medicine. In addition to general markers, EVs are characterized by the presence of specific biomarkers (proteins and miRNAs) that allow the identification of their cell or tissue origin...

Although borderline changes (BL) suspicious for acute T-cell-mediated rejection represents a diagnostic category its clinical relevance is questioned leading to heterogeneous therapeutic management. We hypothesized that measuring IL-6 secretion by peripheral blood mononuclear cells identifies patients with ongoing graft damage. We examined the association between secreted IL-6 and the change in estimated glomerular filtration rate at 6 months after the biopsy (ΔeGFR). We then conducted phenotypic and functional studies on patient and mouse innate immune cells in the blood and the kidney...

Recently, everolimus (Evl) has been introduced in the management of hormone receptor-positive metastatic breast cancer, in combination with aromatase inhibitors. Evl-induced acute kidney injury has hitherto been described in other malignancies, especially renal cell cancer, but only once before in a patient with breast cancer. We describe two cases of Evl-associated nephrotoxicity in patients with breast cancer, one of whom underwent a renal biopsy showing acute tubular necrosis. Both our patients improved after withdrawal of the offending agent and have normal renal functions on follow-up...
