Stephanie G Yi, Richard J Knight, Keri E Lunsford
PURPOSE OF REVIEW: BK virus is a significant risk factor for kidney allograft dysfunction and loss among renal transplant recipients. Currently, there is no proven effective treatment except for the reduction of immunosuppression. In this review, we discuss diagnostic challenges and current treatment options for BK in kidney transplant recipients. RECENT FINDINGS: Antiviral and antibiotic therapies have been employed for BK viraemia with variable efficacy. In addition, novel therapeutic regimens such as adoptive transfer of targeted T cells have been described as possible treatment options for recipients with BK nephropathy...

AIM: Acute kidney injury (AKI) is common following deliberate self-poisoning with a combination washing powder containing oxalic acid (H2C2O4) and potassium permanganate (KMnO4). Early and rapid increases in serum creatinine (sCr) follow severe poisoning. We investigated the relationship of these increases with direct nephrotoxicity in an ongoing multicenter prospective cohort study in Sri Lanka exploring AKI following poisoning. METHODS: Multiple measures of change in kidney function were evaluated in 48 consenting patients who had serial sCr and serum cystatin C (sCysC) data available...

A large number of previous clinical studies have reported a delayed graft function for brain dead donors, when compared with living relatives or cadaveric organ transplantations. However, there is no accurate method for the quality evaluation of kidneys from brain‑dead donors. In the present study, two‑dimensional gel electrophoresis and MALDI‑TOF MS‑based comparative proteomic analysis were conducted to profile the differentially‑expressed proteins between brain death and the control group renal tissues...

INTRODUCTION: Paraphenylene diamine (PPD) ingestion is manifesting as one of the more common ways of committing suicide in Southern Punjab, Pakistan, especially Bahawalpur. PPD is an ingredient of a compound commonly known "Kala Pathar" which means "Black Stone" in Urdu. It is readily available in the market at low cost and is used to dye hair and fur. Its intoxication inhibits cellular oxidation and affects the muscles causing rhabdomyolysis. This leads to myoglobinuria followed by renal failure and edema of face and throat resulting in respiratory difficulty...

Magnetic resonance imaging (MRI) examinations provide high-resolution information about the anatomic structure of the kidneys and are used to measure total kidney volume (TKV) in patients with Autosomal Dominant Polycystic Kidney Disease (ADPKD). Height-adjusted TKV (HtTKV) has become the gold-standard imaging biomarker for ADPKD progression at early stages of the disease when estimated glomerular filtration rate (eGFR) is still normal. However, HtTKV does not take advantage of the wealth of information provided by MRI...

The ATP-binding cassette family transporter MRP2 (multidrug resistance-associated protein 2), encoded by the ABCC2 gene, is involved in the renal excretion of numerous xenobiotics and it is likely that it also transports many endogenous molecules arising from not only normal essential metabolic processes but also from environmental toxins or food intake. We used a targeted gas chromatography-mass spectrometry metabolomics analysis to study whether endogenous organic anions are differentially excreted in urines of healthy volunteers according to their genotype for three functional single nucleotide polymorphisms (SNPs) in ABCC2...

In Africa, the combination of noncommunicable diseases, infectious diseases, exposure to environmental toxins, and acute kidney injury related to trauma and childbirth are driving an epidemic of chronic kidney disease and end-stage renal disease (ESRD). Good registry data can inform the planning of renal services and can be used to argue for better resource allocation, audit the delivery and quality of care, and monitor the impact of interventions. Few African countries have established renal registries and most have failed owing to resource constraints...

BACKGROUND/AIMS: Bleeding is the most common complication after renal biopsy. Although numerous predictors of bleeding have been reported, it remains unclear whether arterial stiffness affects bleeding complications. METHOD: We performed an observational study of the renal biopsies performed in our division over an approximately 6-year period (May 2010 to May 2016). The clinical and laboratory factors were analyzed to reveal the risk factors associated with bleeding, with a focus on anemia (defined as a ≥10% decrease in hemoglobin [Hb] after biopsy)...

BACKGROUND/AIMS: Contrast induced acute kidney injury (CI-AKI) remains a serious complication of contrast media enhanced procedures like coronary angiography. There is still a lack of established biomarkers that help to identify patients at high risk for short and long-term complications. The aim of the current study was to evaluate plasma kynurenine as a predictive biomarker for CI-AKI and long-term complications, measured by the combined endpoint "major adverse kidney events" (MAKE) up to 120 days after CM application...

BACKGROUND & AIMS: Resting energy expenditure (REE) changes in patients with chronic kidney disease (CKD) may contribute to mortality increase. The obesity and inflammation is associated with high REE and when not compensated by adequate intake, may determine an unfavorable clinical outcome in this population. We aimed to evaluate the influence of metabolic syndrome (MetS) on REE in CKD patients. METHODS: One hundred eighty-three patients were stratified according to glomerular filtration rate (GFR) and divided in groups: without CKD (GFR > 60 ml/min/1...

Ian M Graham, Alberico L Catapano, Nathan D Wong
Examination of the current the American College of Cardiology/American Heart Association (ACC/AHA) and European Society of Cardiology/European Atherosclerosis Society (ESC/EAS) guidelines on the prevention of cardiovascular disease and the management of dyslipidemias finds much common ground. Both note that Atherosclerotic cardiovascular disease (ASCVD) is, in most people, the product of a number of risk factors, notably tobacco exposure, hyperlipidemia, hypertension, inactivity, overweight and diabetes. They stress that risk calculators can help in the assessment of risk in apparently healthy persons...

The universal clinical use of multi-targeted tyrosine kinase inhibitors (TKIs) in patients diagnosed with advanced renal cell carcinoma (RCC) has significantly prolonged their estimated survival times and their quality of life. However, several adverse side-effects associated predominantly with the inhibition of the vascular endothelial growth factor receptor by these drugs may prove to be potentially life-threatening. One adverse event that is only rarely observed with the use of TKIs in this clinical setting is acute pancreatitis...
