BACKGROUND: We have previously reported on a novel organ-specific immunomodifying therapy that provides protection from early allograft rejection in the absence of systemic immunosuppressive drugs. This novel therapy is a nano-barrier membrane called ImmunoCloak, consisting of a matrix of laminin, proteoglycans, fibronectin and collagens. The membrane "immunocloaks" the luminal surfaces within the renal vasculature by covering the point of contact between donor vascular endothelial cells and the recipient's immune cells; without adversely affecting renal function...

PURPOSE OF REVIEW: Acute kidney injury is common and is associated with increased morbidity and mortality. Rates of acute kidney injury in most settings remain high and in some settings are increasing. Moreover, outcomes associated with acute kidney injury remain relatively poor. This review focuses on recent advances in understanding of acute kidney injury and discusses possible interventions based on these advances. RECENT FINDINGS: Acute kidney injury is not a disease with a single etiology and clinical course but rather a loose collection of syndromes whose unifying phenotype is an acute loss of glomerular filtration...

Previous study has demonstrated that puerarin (PU) exerts nephroprotective effect against Pb-induced cytotoxicity in primary rat proximal tubular (rPT) cells. Autophagy can protect cells from various cytotoxic stimuli, but its role in the process of PU against Pb-induced nephrotoxicity is still unknown. This study aims to investigate whether PU can alleviate Pb-induced renal damage by recovering autophagy. Data showed that Pb inhibited the autophagic flux, as evidenced by the accumulation of LC3-II and p62 as well as the confocal microscopy analysis of GFP-LC3 puncta and punctate spots of monodansylcadaverine staining, whereas coadministration of PU could restore Pb-induced autophagy inhibition...

Acute kidney injury (AKI) is a frequent complication of multiple myeloma and is associated with increased short-term mortality. Additionally, even a single episode of AKI can eventually lead to end-stage renal disease (ESRD), significantly reducing quality of life and long-term survival. In the setting of multiple myeloma, severe AKI (requiring dialysis) is typically secondary to cast nephropathy (CN). Renal injury in CN is due to intratubular obstruction from precipitation of monoclonal serum free light chains (sFLC) as well as direct tubular toxicity of sFLC via stimulation of nuclear factor (NF)κB inflammatory pathways...

BACKGROUND: A new form of amphotericin B (AmB)- complex with copper (II) ions (AmB-Cu(2+)) - is less toxic to human renal cells. Cytokines, including Tumor Necrosis Factor (TNF), are responsible for nephrotoxicity observed in patients treated with AmB. Another problem during therapy is the occurrence of oxidized forms of AmB (AmB-ox) in patients' circulation. To elucidate the molecular mechanism responsible for the reduction of the toxicity of AmB-Cu(2+), we evaluated the expression of genes encoding TNF and its receptors alongside encoding proteins involved in TNF-induced signalization...

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...

Hump-nosed viper (Hypnale hypnale; HNV) is one of the six major snake species in Sri Lanka that cause envenomation. Nephrotoxicity, coagulopathy, and neurotoxicity are wellrecognized features of its envenomation. Type 4 renal tubular acidosis (RTA4) has only once been described previously in this condition, and we report two further cases. Two patients aged 53 and 51 presented following HNV bites with acute kidney injury and microangiopathic hemolytic anemia. Both underwent multiple cycles of hemodialysis until the polyuric phase was reached...

Nickel is an abundant carcinogenic and nephrotoxic metal whose activity leads to renal impairment. Previous studies have shown a protective effect of simultaneous vitamin C administration on acute and chronic nickel toxicity. However, very little research relating to the effect of vitamin C pretreatment in preventing nickel-induced acute nephrotoxicity is available. Therefore, the present study aimed to determine the efficiency of vitamin C (VC) pretreatment in preventing acute renal toxicity of nickel. Mice were pretreated orally with vitamin C (16...

Since their clinical introduction in 1988, gadolinium-based contrast agents (GBCAs) have demonstrated an excellent safety profile with a reported acute adverse reaction rate ranging from 0.01% to 2%. By comparison, the acute adverse reaction rate of low osmolar nonionic computed tomography contrast agents (CTCs) ranges from 0.7% to 3.1%. Many of the risk factors associated with CTC reactions (drug allergies, asthma, atopy, prior contrast reaction) also point toward an increased incidence of acute adverse events to GBCAs...

Neuroendocrine tumors (NETs) comprise a heterogeneous group of malignancies, with differences in prognosis and effective therapies. Traditionally, NETs have been characterized by tumor grade, site of primary tumor, functional status, and presence of underlying familial syndrome. However, increased feasibility and utilization of next-generation sequencing and other methodologies have revealed new genomic and epigenetic aberrations. In the last decade, treatment options available for metastatic well-differentiated gastroenteropancreatic (GEP) NETs have expanded, with approval of antiangiogenic and mTOR-directed targeted therapies, and our armamentarium of active therapies is likely to further increase...

We evaluated activity of apramycin, a non-ototoxic/non-nephrotoxic aminocyclitol against 141 clinical Enterobacteriaceae isolates, 51% of which were non-susceptible to carbapenems (CRE). Among CRE, 70.8% were apramycin susceptible, which compared favorably to aminoglycosides in current clinical use. Our data suggest that apramycin deserves further investigation as a repurposed, anti-CRE therapeutic.

Kidney transplantation immunosuppression relies on a calcineurin inhibitor backbone. Calcineurin inhibitors have reduced early-acute rejection rates but failed to improve long-term allograft survival. Their nephrotoxicity has shifted the focus of investigation to calcineurin inhibitor-free regimens. Costimulation blockade with belatacept, a second generation, higher avidity variant of CTLA4-Ig, has emerged as part of a calcineurin inhibitor-free regimen. Belatacept has demonstrated superior glomerular filtration rate compared with calcineurin inhibitors albeit with an increased risk of early and histologically severe rejection...

Kidney transplantation is well established as the best treatment option for end-stage kidney disease. It confers not only a better quality of life but also a significant survival advantage compared to dialysis. However, despite significant improvement in short-term kidney transplant graft survival over the past three decades, long-term graft survival remains suboptimal. Concerns about the possible contribution of chronic calcineurin inhibitor (CNI) nephrotoxicity to late allograft failure and other serious adverse effects of currently used immunosuppressive agents (especially corticosteroids) have led to increasing interest in developing regimens which may better preserve kidney allograft function and minimize other immunosuppression-related problems without increasing the risk of rejection...
