BACKGROUND: Anti-TNF (Tumor necrosis factor) therapy is effective in treating pediatric patients with refractory rheumatic disease. There is however a concern that anti-TNF usage may increase the risk of malignancy. Reports on specific types of malignancy in this patient population have been emerging over the past decade, but there is a need for additional malignancy reports, as these events are rare. Therefore, a retrospective chart review was performed on the biologic database of pediatric rheumatology patients at The Hospital for Sick Children (SickKids) from 1997 to 2013 for neoplasms, patient demographic information and rheumatologic treatment course...

BACKGROUND & AIM: Recent studies suggest that uric acid (UA) is a mediator of diabetic nephropathy. We hypothesized that serum UA would associate with the prevalence of diabetic nephropathy in youth with type 1 diabetes (T1D), and that this relationship would differ by sex. METHODS: We examined 120 young boys and the same number of girls with T1D. C-reactive protein (CRP), interleukin-6 (IL-6), interleukin-10 (IL-10), tumor necrosis factor α (TNF-α), uric acid, cystatin C serum concentrations, albumin excretion rate and blood pressure were also analysed...

In patients with renal cell carcinoma (RCC), postoperative upstaging including perinephric fat invasion (PNI) and renal sinus invasion (RSI) leads to unfavorable oncological outcomes. Determining the preoperative risk factors for postoperative upstaging could be beneficial for treatment planning. In this study, 267 RCC patients who underwent radical nephrectomy were studied retrospectively. The RSI incidence was significantly greater than that of PNI. Kaplan-Meier analysis revealed that patients with RSI, PNI, and RSI plus PNI had poorer disease-free-survival than those with neither RSI nor PNI...

The association between cytomegalovirus (CMV) reactivation and cardiovascular risk has been reported in solid organ transplant populations; however, it has yet to be assessed in liver transplantation (LT). We aim to evaluate whether CMV reactivation is associated with cardiovascular events (CVE) in HCV-LT patients. Methods: LT patients (2010 and 2014) due to HCV cirrhosis were included. Clinically significant CMV (CS-CMV) was defined as viral load (VL)>5000 copies/mL, need of therapy or CMV disease. Baseline variables and end-point measures (CVE, survival, severe recurrent hepatitis C, de novo tumors and diabetes) were collected...

Gene expression is negatively regulated by microRNAs (miRNAs), which commonly act as tumor oncogenes or suppressors. Previous results were inconsistent concerning the relationship between polymorphisms in miRNAs and risk of urological neoplasms. Here, we conducted a comprehensive literature research on diverse databases aiming at enrolling all eligible studies up to August 31, 2016. A total of 13 publications comprising 29 case-control studies were enrolled for three polymorphisms in three miRNAs. Overall analyses suggested significant associations between miR-146a rs2910164 polymorphism and urological neoplasms risk in allelic, homozygote and recessive models...

BACKGROUND: The inflammatory tumor microenvironment is crucial for effective tumor control and long-term immunosuppression has been identified as a major risk factor for skin carcinogenesis. In solid organ transplant recipients (OTR) undergoing long-term pharmacologic immunosuppression an increased incidence of cutaneous squamous cell carcinoma (SCC) and more aggressive tumor growth compared to immunocompetent patients (IC) has been reported. OBJECTIVES: To determine the density and phenotype of immune cells infiltrating SCC and surrounding skin in OTR, and to characterize the microanatomical distribution patterns in comparison to IC...

von Hippel-Lindau (VHL) disease is an autosomal dominant syndrome caused by mutations in the VHL tumor-suppressor gene, leading to the dysregulation of many hypoxia-induced genes. Affected individuals are at increased risk of developing recurrent and bilateral kidney cysts and dysplastic lesions which may progress to clear cell renal cell carcinoma (ccRCC). Following the eponymous VHL gene inactivation, ccRCCs evolve through additional genetic alterations, resulting in both intratumor and intertumor heterogeneity...

Absence of neoplastic disease in the organ-recipient is required in order to allow organ transplantation. Due to its rarity, no data regarding management of patients with Multiple endocrine neoplasia type 1 (MEN1) and end-stage renal failure candidates for kidney transplantation are available. A 36 year-old man was referred to the present hospital with MEN1, with a neuroendocrine pancreatic tumor and primary hyperparathyroidism and associated Alport syndrome with end stage renal failure. The present study aimed to establish the eligibility of the patient for a kidney transplantation...

Clear cell renal cell carcinoma (ccRCC) is the most common and aggressive subtype of renal cancer. STAT3 pathway is altered in these tumors and p-STAT3 Ser727 is an independent prognostic factor for ccRCC. Protein kinase CK2 is altered in different types of tumors and overexpression of CK2α is considered predictive of bad prognosis and metastatic risk. CK2 subunits analyses in ccRCC samples showed increased CK2α/α' nuclear content in all cases, but decreased cytosolic CK2β (CK2βcyt) levels in the more advanced tumors...

Leptin plays an important role in carcinogenesis as leptin/leptin receptor signaling promotes the angiogenesis, proliferation, and inhibits epithelial cell apoptosis. Variants in the leptin receptor gene have potential associations with renal cell carcinoma (RCC). We aimed to investigate association of rs1137101 (A/G) polymorphism at LEPR gene with risk of RCC and patients survival. 123 individuals were classified into group I: 73 RCC patients and group II: 50 healthy controls. Genotyping of the Gln223Arg (A/G) polymorphism rs1137101 at LEPR gene was analyzed using allelic discrimination assay by Real-Time PCR technique...

BACKGROUND: Gross genetic causes for SCT are unknown; however, it might be associated with other abnormalities. We assessed the incidence of associated abnormalities in a large national cohort of neonates with SCT and aimed to identify predictive risk factors. PROCEDURE: The medical records were reviewed of 235 consecutive neonates with SCT treated at the six pediatric surgical centers in the Netherlands from 1970 to 2010. Potential risk factors for associated abnormalities analyzed included sex, gestational age, tumor-volume/histology and Altman-classification...

Chronic alcoholism is a risk factor for kidney injury. Clonidine is an α 2 -adrenergic receptor/imidazoline-1 receptor agonist that can reduce blood pressure and maintain renal functions. This study aims to investigate the possible ameliorative effects of clonidine on ethanol induced kidney injury and its mechanism of action. Kidney injury was induced in rats by adding ethanol to drinking water for eight weeks. Clonidine effects on kidney functions and histopathology were measured. Moreover, phentolamine (α-adrenergic receptor antagonist), efaroxan (imidazoline-1 receptor antagonist) and rilmenidine (imidazoline-1 receptor agonist) were used to clarify the role of imidazoline-1 receptor in mediating renal ameliorative effects...

BACKGROUND: Uric acid (UA) is still considered a risk factor, or even a causative agent, for chronic kidney disease (CKD); however, a few, important, clinical questions remain unanswered; in particular: when and whether urate-lowering therapy should be commenced in subjects with asymptomatic hyperuricemia and/or monosodium urate crystals deposition? What is the most appropriate UA target to be achieved and how long does it need to be maintained? How does treatment need be adjusted in patients with chronic kidney disease? SUMMARY: The observational and intervention studies available do not fully answer such questions, and a treatment to target trial is required...
