BACKGROUND: Nivolumab (Opdivo™) is a novel IgG4 subclass programmed death-1 (PD-1) inhibiting antibody that has demonstrated breakthrough-designation anti-tumor activity. To date, clinical trials of nivolumab and other checkpoint inhibitors have generally excluded patients with solid organ transplantation and patients with concurrent immunosuppression. However, organ transplant recipients are at high-risk of development of malignancy as a result of suppressed immune surveillance of cancer...

FMS-like tyrosine kinase 3 (FLT3) is one of the most commonly mutated genes in AML. FLT3 is mutated in ~30% of patients with AML, either by internal tandem duplications (FLT3-ITD) of the juxta-membrane domain or by a point mutation, usually involving the tyrosine kinase domain. Several FLT3 tyrosine kinase inhibitors are being evaluated in multiple studies aiming at improving outcomes. The most widely used is sorafenib, a potent multikinase inhibitor approved for hepatocellular carcinoma and renal cell carcinoma...

BACKGROUND: Autosomal dominant polycystic kidney disease (ADPKD) is characterized by multiple, large renal cysts and impaired kidney function. Although the reason for the development of kidney cysts is unknown, ADPKD is associated with cell cycle arrest and abundant apoptosis of renal tubular epithelial cells. AIMS: We asked whether serum-soluble TNF-related apoptosis-inducing ligand (sTRAIL) might underlie ADPKD. STUDY DESIGN: Case-control study...

A 67-year-old man presented at our hospital with severe edema on the left side of his neck, chest and brachial regions. He had a history of right radical nephrectomy due to renal cell carcinoma (RCC, clear cell subtype, stage II) 15 years earlier. Thereafter, metastases to the pancreatic tail and right lung, and left lung metastasis were removed at 8 years and 11 years, respectively, after the nephrectomy. Four years earlier, he had also undergone total gastrectomy for gastric carcinoma (poorly differentiated adenocarcinoma, stage IV) and subsequent maintenance chemotherapy for gastric carcinoma...

The burden of cardiovascular diseases (CVD) in general and heart failure (HF) in particular continues to increase worldwide. CVD are major contributors to death and morbidity and recognized as important drivers of healthcare expenditure. Chronic overactivity of the renin-angiotensin-aldosterone system (RAAS) plays a key role in human hypertension and HF pathophysiology. RAAS is fundamental in the overall regulation of cardiovascular homeostasis through the actions of hormones, which regulate vascular tone, and specifically blood pressure through vasoconstriction and renal sodium and water retention...

According to the seventh report of Joint National Committee (JNC 7), hypertensive emergency (HE), a kind of hypertensive crisis, is defined as a sudden and abrupt elevation in blood pressure so as to cause acute target organ dysfunctions, including central nervous system, cardiovascular system or kidneys. Patients with HE require immediate reduction in markedly elevated blood pressure. Currently, there are no international guidelines for children HE, so the JNC definition is commonly used. Hypertensive emergency in children is rare but a life-threatening emergency...

Blockade of the renin-angiotensin-aldosterone system (RAAS) can be accomplished at the level of the angiotensin-generating enzymes renin and angiotensin-converting enzyme (ACE; using renin inhibitors or ACE inhibitors), the type 1 angiotensin II (AT1) receptor or mineralocorticoid receptor (MR; using angiotensin receptor blockers [ARBs] or MR blockers) and/or renin release (using beta-blockers). Several of these drugs are often combined-for example in heart failure-but such approaches may ultimately lead to RAAS annihilation with adverse consequences such as hypotension, renal dysfunction and hyperkalaemia...

Treatment-resistant hypertension (TRH) is defined as the failure to achieve an office BP target of <140/90 mmHg (<130/80 mmHg in patients with chronic kidney disease (CKD) or diabetes) in patients with hypertension (HT), despite adherence to at least 3 antihypertensive medications at optimal tolerated doses, ideally including a diuretic (Calhoun et al., Circulation 2008). TRH identifies patients with hard-to-treat HT, who might benefit from specialist investigation and treatment. Although some studies put the prevalence of TRH as >10%, these levels may be inflated by white-coat hypertension and poor adherence...

Beginning with the Veterans Administration (VA) Cooperative Hypertension Study of the 1960 s, blood pressure (BP) lowering with antihypertensive medications has been shown to reduce major cardiovascular (CV) outcomes, including coronary heart disease, stroke, heart failure (HF) and CV and all-cause mortality in randomized controlled CV outcome trials. Multiple drugs were usually required in these trials to lower BP in treated participants. Medication regimens in the early trials, including the VA trial, included a thiazide-type diuretic (TTD) as initial therapy...

Hypertension prevalence rates in most urbanized areas of Africa range from 20-30%, with a recent systematic review reporting 16.2% for sub-Saharan Africa. These rates are lower than those in the West but the age standardized rates are higher than in other regions of the world. The attendant morbidity and mortality are disproportionately high. For example, failure of nocturnal dipping and microalbuminuria, predictive of vascular disease, occur relatively early in the course of hypertension and predispose to early vascular disease...

Tissue calcification is a common complication in patients on continuous hemodialysis (HD) for chronic renal failure; however, severe calcification is unusual. Three distinct clinical types of extraosseous calcifications are found in uremic patients: vascular calcification, periarticular (tumoral) calcification, and visceral calcification (heart, lung, and kidney). We report a case of a young chronic HD patient who presented with extensive metastatic calcifi cations both vascular, visceral specially localized in the lungs, and periarticular with progressively increasing multiple subcutaneous swellings...

The IgG4-related disease has a wide clinical spectrum where multiple organs can be affected, and the diagnosis depends on typical histopathological findings and an elevated IgG4 expression in plasma cells in the affected tissue. We describe the clinical presentation and evolution of a patient with acute tubulointerstitial nephritis, severe kidney failure and systemic manifestations such as lymphadenomegaly and chronic pancreatitis. The diagnosis was confirmed by the clinical picture and kidney and lymph node histopathology, in which immunohistochemistry of the lymphoid tissue showed policlonality and increased expression of IgG4, with a IgG4/total IgG ratio > 80%...

BACKGROUND: Intra-abdominal hypertension (IAH) is frequently present in critically ill patients and is an independent predictor for mortality. Better recognition of clinically important thresholds is necessary. Increased intra-abdominal pressure (IAP) is associated with renal dysfunction, and renal failure is one of the most consistently described organ dysfunctions associated with IAH. Obesity is also associated with kidney injury. The underlying mechanisms are not yet fully understood...

Neutrophil gelatinase-associated lipocalin, known also as 24p3 lipocalin, lipocalin-2 or uterocalin (in mouse), is a small secretory protein binding small molecular weight ligands which takes part in numerous processes including apoptosis induction in leukocytes, iron transport, smell, and prostaglandins and retinol transport [19]. It was discovered in activated neutrophils as a covalent peptide associated with human gelatinase neutrophils [7]. Neutrophil lipocalin is secreted physiologically in the digestive system, respiratory tract, renal tubular cells, liver or immunity system...

Background: Ureteral stenosis is part of the common complications of renal graft reported in 3% to 7% of cases. Multiple treatments have been introduced regarding length and position of the stenosis. Metal stents for urologic purpose were created in 1998. Double percutaneous antegrade and transurethral retrograde access to a ureteral stenosis to a long-term metal stent procedure has been rarely described. Case Presentation: Here, we present a case of a ureteral stricture in a double ipsilateral kidney graft with a common ureter...
