BACKGROUND: A wide variety of kidney diseases ultimately lead to tubulointerstitial damage. The initial site of injury is usually the renal tubules, with activation of fibroblasts occurring later. Self-limited disease is characterized by transient cellular activation with timed deactivation and ultimately a return to normal functioning, whereas sustained responses characterize chronic disease and the development of irreversible fibrosis. The underlying molecular and cellular mechanisms of this cascade of events remain an area of active research...

BACKGROUND: Autosomal dominant polycystic kidney disease (PKD) or autosomal recessive PKD is caused by a mutation in the PKD1, PKD2 or PKHD1 gene, which encodes polycystin-1, polycystin-2 or fibrocystin, respectively. Embryonic and postnatal mutation studies show that transport or channel function is dysregulated before the initiation of cystogenesis, suggesting that the abnormality of transport or channel function plays a critical role in the pathology of PKD. SUMMARY: Polycystin-2 by itself is a calcium-permeable cation channel, and its channel function can be regulated by polycystin-1 or fibrocystin...

INTRODUCTION: Ipilimumab is an immune checkpoint inhibitor targeting cytotoxic T-lymphocyte associated antigen 4 (CTLA4), approved to treat metastatic melanoma. It was the first therapy shown to prolong survival in a large, randomized clinical trial. However, immune-related adverse events are common and can be severe. Enterocolitis is a common adverse event with ipilimumab, but enteritis without colitis has not been previously described. CASE REPORT: An 83-year-old man presented to our hospital with grade 3 diarrhea for 5 days...

Non-alcoholic fatty liver disease (NAFLD) is one of the most common comorbidities associated with overweight and metabolic syndrome (MetS). Importantly, NAFLD is one of its most dangerous complications because it can lead to severe liver pathologies, including fibrosis, cirrhosis and hepatic cellular carcinoma. Given the increasing worldwide prevalence of obesity, NAFLD has become the most common cause of chronic liver disease and therefore is a major global health problem. Currently, NAFLD is predominantly regarded as a hepatic manifestation of MetS...

Crush syndrome is a fine example of how pathology can play a direct role in revealing the best treatment and management for diseases. It can occur when crush injuries are sustained. Skeletal muscle becomes damaged under the weight of a heavy object, and victims experience severe shock and renal failure. The discovery of the pathology of crush syndrome belongs to two individuals: Seigo Minami and Eric Bywaters. They separately helped to define the pathogenesis of crush syndrome during World Wars I and II. Seigo Minami is believed to have been the first to record the pathogenesis of crush syndrome...

Aniridia is a rare congenital disease characterized by eye development defects, in which the more evident clinical manifestation is iris absence or malformation. In most of the patients, aniridia is associated to PAX6 gene point mutations or deletions. When these deletions are large and involve other genes, a more complex disease, named WAGR syndrome, arises. In order to develop a new tool to analyze aniridia and WAGR subjects, a CGH array (CGHa) of the PAX6 genomic region was set up. We generated a custom microarray kit using an oligonucleotide-based platform that allows high resolution molecular profiling of genomic aberrations in 20 Mb of the 11p13 chromosomal region, centered on the PAX6 gene...

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...

A 31-year-old man presented with sudden right flank pain. We found a right renal tumor with a perirenal hematoma on enhanced abdominal computed tomography (CT), which suggested spontaneous rupture of the renal tumor. The tumor was located at the upper pole of the right kidney, and was not enhanced. Magnetic resonance imaging (MRI) showed slightly enhanced renal tumor, and positron emission tomography (PET) showed a hot spot in the renal mass. His anemia was getting worse, and we assumed that the renal mass was malignant...

Adoptive transfer of regulatory T cells (Tregs) can delay disease progression and reduce mortality in lupus-prone mice. Here, we tested whether complex (IL-2C) consisting of IL-2 and anti-IL-2 monoclonal antibody (JES6-1) ameliorates lupus nephritis by expanding Tregs as an alternative to problematic Treg infusion therapy. IL-2C treatment of NZB/W F1 mice induced an effective and sustained expansion of CD4(+)CD25(+)Foxp3(+) Tregs in both the kidneys and spleen along with decreased renal infiltration of T cells, B cells, and innate immune cells...

Atherosclerosis is an important predictor of mortality in patients with chronic kidney disease (CKD) and is associated with a wide inflammatory response. The aim of this study is to evaluate in vitro how different membranes can remove mediators associated with this pathology in a closed loop dialysis model. We performed experimental hemofiltration in vitro using three different membrane materials. Human plasma was preliminarily incubated with various inflammatory mediators and filtered in a closed loop circulation model for 240 min...

BACKGROUND: Rhabdomyolysis is a pathologic condition in which intracellular muscle constituents leak into the blood circulation. It is usually caused by muscle trauma. "Spinning" is an indoor form of cycling where participants use a special stationary exercise bicycle with a weighted flywheel and undergo high intensity cycling classes focusing on endurance. There have been several case reports in the literature of exertional rhabdomyolysis following spin class. METHODS: Our nephrology practices have diagnosed a number of cases of symptomatic patients presenting to our emergency departments following their first spin classes, with histories and creatinine phosphokinase levels diagnostic of exertional rhabdomyolysis...

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...

Marek's disease (MD) is a major cause of mortality in backyard chickens. The diagnosis of MD is complex, however, and knowledge of Marek's disease virus (MDV) in spontaneous field cases such as in backyard chickens is largely unknown. In this study, 40 backyard chickens with a presumptive MD diagnosis based on histologic lymphoid infiltrations in peripheral nerves with and without lymphomas were investigated. Twenty-eight of the birds were submitted to the diagnostic laboratory for disease explorations, and 12 chickens were from a flock in which some members demonstrated anisocoria and pupil irregularities compatible with ocular MD...

Statins, 3-hydroxy-3-methyl-glutaryl-coenzyme A reductase inhibitors have been shown to improve diabetic nephropathy. However, whether they provide protection via Histone deacetylases (HDAC) inhibition is not clear. We conducted a comparative evaluation of Atorvastatin (AT) versus the non-statin cholesterol-lowering drug, Ezetimibe (EZT) on severity of diabetic nephropathy. Streptozotocin-treated male Wistar rats were fed a cholesterol-supplemented diet and gavaged daily with vehicle, AT or EZT. Control rats received normal diet and gavaged vehicle (n = 8-9/group)...

Calcific uremic arteriolopathy (CUA), also known as calciphylaxis, is a rare condition most frequently seen in patients with advanced chronic kidney disease. The clinical picture is characterized by painful skin lesions and ulcerations. The underlying pathology is medial calcification and intimal proliferation with microthrombi of small arteries. CUA is commonly associated with secondary hyperparathyroidism and high serum calcium and phosphate products. This article reports an atypical case where CUA developed after parathyroidectomy and in the course of treatment of hungry bone syndrome...

With improvements in the care of patients with sickle hemoglobinopathies, sickle cell disease (SCD) has evolved from a disease that was fatal in childhood into one in which most survive past their 5th decade and some into old age. As a result, the renal complications of sickle hemoglobinopathies, which are age dependent, have emerged as a common and serious complication of SCD. Approximately 14 - 18% of mortality in SCD is attributed to chronic kidney disease (CKD), which develops in 1/3 of individuals with SCD and progresses to end-stage renal disease in 4 - 18% of them...

Peter Rez
The mineral phase makes up most of the mass of a kidney stone. Minerals all come in the form of crystals that are regular arrangements of atoms or molecular groupings at the atomic scale, bounded macroscopically by well-defined crystal faces. Pathologic nephroliths are a polycrystalline aggregate of submicron crystals. Organic macromolecules clearly have an important role in either promoting or preventing aggregation and in altering the morphology of individual submicron crystals by influencing the surface energies of different faces...
