Suicidal erythrocyte death or eryptosis contributes to or even accounts for anemia in a wide variety of clinical conditions, such as iron deficiency, dehydration, hyperphosphatemia, vitamin D excess, chronic kidney disease (CKD), hemolytic-uremic syndrome, diabetes, hepatic failure, malignancy, arteriitis, sepsis, fever, malaria, sickle-cell disease, beta-thalassemia, Hb-C and G6PD-deficiency, Wilsons disease, as well as advanced age. Moreover, eryptosis is triggered by a myriad of xenobiotics and endogenous substances including cytotoxic drugs and uremic toxins...

BACKGROUND: In patients undergoing general anaesthesia, intraoperative hypotension occurs frequently and is associated with adverse outcomes such as postoperative acute kidney failure, myocardial infarction or stroke. A history of chronic hypertension renders patients more susceptible to a decrease in blood pressure (BP) after induction of general anaesthesia. As a patient's BP is generally monitored intermittently via an upper arm cuff, there may be a delay in the detection of hypotension by the anaesthetist...

It is unclear whether black patients with chronic kidney disease (CKD) vs those without CKD who take antihypertensive medication have an increased risk for apparent treatment-resistant hypertension (aTRH). The authors analyzed 1741 Jackson Heart Study participants without aTRH taking antihypertensive medication at baseline. aTRH was defined as uncontrolled blood pressure while taking three antihypertensive medication classes or taking four or more antihypertensive medication classes, regardless of blood pressure level...

This case describes a patient being considered for combined liver-kidney transplantation for Caroli's disease with a failed renal transplant. A chronic septic focus could not be located with standard imaging techniques, such as ultrasonography and computed tomography. This case report highlights the observation that a retained non-functioning transplant can be the cause of fever of unknown origin and PET-CT can be useful in diagnosing these challenging cases.

PURPOSE: To validate an optimal 12-fold accelerated real-time cine MRI pulse sequence with radial k-space sampling and compressed sensing (CS) in patients at 1.5T and 3T. METHODS: We used two strategies to reduce image artifacts arising from gradient delays and eddy currents in radial k-space sampling with balanced steady-state free precession readout. We validated this pulse sequence against a standard breath-hold cine sequence in two patient cohorts: a myocardial infarction (n = 16) group at 1...

BACKGROUND: Pivotal clinical trials found ticagrelor reduced ischemic complications to a greater extent than clopidogrel and what is more, the benefit gradually increased with the reduction on creatinine clearance. However, the underlying mechanisms remains poorly explored. METHODS: This is a single-center, prospective, randomized clinical trial involving 60 hospitalized P2Y12 inhibitor naïve patients with CKD (eGFR<60ml/min/1.73m(2) ) and NSTE-ACS. Eligible patients were randomly assigned in a 1:1 ratio to receive ticagrelor(180 mg loading dose, then 90 mg twice daily followed) or clopidogrel(600 mg loading dose, then 75 mg qd followed)...

Benjamin Lamglait, Marielle Vandenbunder-Beltrame
Symmetric dimethylarginine (SDMA) has been shown to be a valuable biomarker for early detection of chronic kidney disease (CKD) in canine and feline patients. Recognition of early (subclinical) kidney disease would be of value in cheetahs (Acinonyx jubatus) as prevalence of CKD is relatively high in this species in captivity. Fifty-eight banked serum and plasma samples from seven adult cheetahs that died of CKD were analyzed for creatinine, urea, and SDMA. A marked increase in SDMA was noted on five of the tested cheetahs earlier than the rise of serum creatinine and urea (estimated 8-35 mo; mean 21...

The blood protozoan Trypanosoma evansi, which is transmitted by biting flies, is frequently neglected due to subclinical infections. This report describes a case of trypanosomiasis due to T. evansi in a 9-yr-old male puma (Felis concolor) housed at the Lahore Zoo in Pakistan. Early in January 2015, this male puma presented with chronic lethargy, weight loss, incoordination, hyperthermia, anorexia, sunken eyes, and unthriftiness. Microscopic examination of Giemsa-stained blood smears showed numerous Trypanosoma parasites...

BACKGROUND: Renal dysfunction negatively impacts survival in acute coronary syndrome patients. The Berlin Initiative Study creatinine-based (BIScrea) equation has recently been proposed for renal function assessment in older persons. However, up to now it is unknown if the superiority of the new BIScrea equation, with respect to the most recommended chronic kidney disease epidemiology collaboration creatinine-based (CKD-EPIcrea) formula, would translate into better risk prediction of adverse events in older patients with acute coronary syndrome...

Slowing down the progression of chronic kidney disease (CKD) and its adverse health outcomes requires the patient's self-management and attention to treatment recommendations. Information technology (IT)-based interventions are increasingly being used to support self-management in patients with chronic diseases such as CKD. We conducted a systematic review of randomized controlled trials (RCTs) to assess the features and effects of IT-based interventions on self-management outcomes of CKD patients. A comprehensive search was conducted in Medline, Scopus, and the Cochrane Library to identify relevant papers that were published until May 2016...

INTRODUCTION: Sequencing peptides included in the urinary proteome identifies the parent proteins and may reveal mechanisms underlying the pathophysiology of chronic kidney disease. METHODS: In 805 randomly recruited Flemish individuals (50.8% women; mean age, 51.1 years), we determined the estimated glomerular filtration rate (eGFR) from serum creatinine using the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation. We categorized eGFR according to the National Kidney Foundation Kidney Disease Outcomes Quality Initiative guideline...

BACKGROUND: Hyperkalemia is a potentially life-threatening condition that patients with heart failure or chronic kidney disease, especially those taking renin-angiotensin-aldosterone system inhibitors, are at high risk of developing. Sodium polystyrene sulfonate (SPS), a current treatment, binds potassium within the gastrointestinal tract to reduce potassium absorption. However, poor palatability limits its long-term use. RDX7675, a novel potassium binder in development for the treatment of hyperkalemia, is a calcium salt of a reengineered polystyrene sulfonate-based resin designed to have enhanced palatability...

Manganese (Mn) is an important mineral element required in trace amounts for development of the human body, while over- or chronic-exposure can cause serious organ toxicity. The current study was designed to evaluate the protective role of quercetin (Qct) against Mn-induced toxicity in the liver, kidney, lung, and hematological parameters in acute and subchronic rat models. Male Sprague Dawley rats were divided into control, Mn (100 mg/kg for acute model and 15 mg/kg for subchronic model), and Mn + Qct (25 and 50 mg/kg) groups in both acute and subchronic models...

Bone-derived fibroblast growth factor 23 (FGF23) is an important endocrine regulator of mineral homeostasis with effects transduced by cognate FGF receptor (FGFR)1-α-Klotho complexes. Circulating FGF23 levels rise precipitously in patients with kidney disease and portend to worse renal and cardiovascular outcomes. De novo expression of FGF23 has been found in the heart and kidney following injury but its significance remains unclear. Studies showing that exposure to chronically high FGF23 concentrations activates hypertrophic gene programmes in the cardiomyocyte, has spawned intense interest in other pathological off-target effects of FGF23 excess...

Pregnancy is probably the most important challenge in young women with chronic kidney disease (CKD). The challenge is greater in developing countries, in which access to dialysis is uneven, and prenatal care for CKD patients is not uniformly available. This case report summarizes some of the challenges faced by pregnant CKD women in a developing country. A 35-year-old woman, affected by an undiagnosed kidney disease, experienced preeclampsia at 24 years of age, and started dialysis in emergency at age 31 in the context of severe preeclampsia in her second pregnancy...

Chronic kidney disease (CKD) is a progressive pathological condition marked by a gradual loss of kidney function. Treatment of CKD is most effective when diagnosed at an early stage and patients are still asymptomatic. However, current diagnostic biomarkers (e.g., serum creatinine and urine albumin) are insufficient for prediction of the pathogenesis of the disease. To address this need, we applied a cell-SELEX (systematic evolution of ligands by exponential enrichment) approach and identified a series of DNA aptamers, which exhibit high affinity and selectivity for cytokine-stimulated cells, resembling some aspects of a CKD phenotype...

REP 2139 is a nucleic acid polymer (NAP) currently under clinical development for chronic hepatitis B (HBV) therapy. This preclinical study investigated different REP 2139 analogs that would display reduced accumulation in the serum and tissues, while retaining an antiviral effect against HBV infection. REP 2139 analogs were evaluated in human plasma, CD-1 mice, cynomolgus monkeys, and Pekin ducks. Discrete ribose transformation to 2'OH in selected riboadenosines resulted in a slow degradation in acidified human plasma that plateaued after 48 hr...
