Metformin intoxication with lactic acidosis, a potentially lethal condition, may develop in diabetic patients when the drug dose is inappropriate and/or its clearance is reduced. Diagnosis and therapy may be delayed due to nonspecific symptoms at presentation, with severe anion gap metabolic acidosis and elevated serum creatinine values being the most prominent laboratory findings. Confirmation requires measurement of serum metformin by high-performance liquid chromatography-tandem mass spectrometry, but this technique is available only at specialized institutions and cannot be relied on as a guide to immediate treatment...

BACKGROUND: Central vein thrombosis or obstruction is a common complication associated with central venous catheters placed for intermittent hemodialysis. The reported outcomes of percutaneous catheter-based interventions reveal high rates of lesion recurrence with varying and frequently limited patency intervals. We present the case of open venous bypass in the treatment of catheter-associated chronic central vein occlusion. METHODS: We report a case of symptomatic arm swelling secondary to central vein stenosis and failed endovascular venous intervention treated by central vein bypass with prosthetic graft through median sternotomy...

BACKGROUND: Chronic kidney disease (CKD) is characterized by progressive irreversible deterioration of renal functions. Advanced stages of CKD are associated with oxidative stress due to the imbalance between oxidant production and antioxidant defense mechanisms. Survival of patients with end stage renal diseases is maintained on variable forms of renal replacement therapies (RRT) which include peritoneal dialysis, hemodialysis, and sometimes renal transplantation. In humans, Nuclear Respiratory Factor 1 (NRF-1) gene encodes for a transcription factor that, together with the transcriptional co-activator encoded by Peroxisome Proliferator activated Receptor Gamma coactivator 1 Alpha (PGC1-a) gene, stimulates the expression of a broad set of nuclear genes (as COX6C) which are involved in mitochondrial biogenesis and functions...

BACKGROUND: Isolated renal allograft aspergillosis is rare and usually presents with fever and decreased glomerular filtration rate. Presentation with obstructive uropathy caused by aspergillus fungal balls is much less common. We report a young male patient who presented with obstructive uropathy secondary to isolated renal allograft aspergillus infection 6 weeks after transplant. He was treated with nephrectomy and antifungal medications. CASE PRESENTATION: A 29-year-old Saudi male patient had a recent living non-related kidney transplantation in Pakistan...

PURPOSE: Traditional anticoagulants used in intermittent hemodialysis (HD) are unfractionated heparin (UFH) and increasingly low molecular weight heparins (LMWHs). Repeated and prolonged exposure to UFH and/or LMWHs may further disturb hemostasis in uremic patients. Vascular adhesion protein-1 (VAP-1) is secreted by vascular smooth muscle cells, adipocytes and endothelial cells with functional monoamine oxidase activity and is elevated in atherosclerosis, diabetes mellitus and obesity...

BACKGROUND: In conventional hemodialysis (HD) treatment, excessive water removal sometimes induces a rapid drop in blood pressure. Intermittent infusion hemodiafiltration (I-HDF) has been developed to improve patients' peripheral circulation by repeated intermittent infusion during HD treatment. SUMMARY: A prospective, multicenter, parallel group comparative trial examined the clinical effectiveness of I-HDF compared with predilution on-line HDF (pre-HDF), the most popular on-line HDF therapy in Japan...

Cefiderocol, a new injectable siderophore cephalosporin antibiotic, has promising in vitro and in vivo activity against Gram-negative bacteria including multidrug-resistant Pseudomonas aeruginosa, Acinetobacter baumannii, and Klebsiella pneumoniae. Cefiderocol is mainly renally eliminated. The pharmacokinetics and safety of cefiderocol in subjects with renal impairment were assessed following a single 1000-mg intravenous 1-hour infusion of cefiderocol. Subjects with mild, moderate, or severe renal impairment and end-stage renal disease (ESRD) requiring hemodialysis were compared with demographically (age, body mass index, and sex) matched healthy subjects with normal renal function...

Reportedly, citrate-based dialysis solution enables heparin dose tapering or even complete exclusion, particularly in postdilution hemodiafiltration (HDF). The aim of the study was to verify this strategy in predilution setting and to assess its short-term safety, efficacy, and biocompatibility. Ten regular hemodialysis patients were assigned to predilution HDF on acetate- and citrate-based dialysis solutions (0.8 mmol/l trisodium citrate) at random order. Acetate HDF was performed using routine dose of heparin while citrate HDF was heparin free...

CONTEXT: Acidemia is a marker of prognosis in methanol poisoning, as well as compounding formate-induced cytotoxicity. Prompt correction of acidemia is a key treatment of methanol toxicity and methods to optimize this are poorly defined. OBJECTIVE: We studied the efficiency of acidemia correction by intermittent hemodialysis (IHD) and continuous renal replacement therapy (CRRT) in a mass outbreak of methanol poisoning. METHODS: The study was designed as observational cohort study...

Cefiderocol, a novel parenteral siderophore cephalosporin, exhibits potent efficacy against most Gram-negative bacteria, including carbapenem-resistant strains. Since cefiderocol is excreted primarily via the kidneys, this study was conducted to develop a population pharmacokinetics (PK) model to determine dose adjustment based on renal function. Population PK models were developed based on data for cefiderocol concentrations in plasma, urine, and dialysate with a nonlinear mixed-effects model approach. Monte-Carlo simulations were conducted to calculate the probability of target attainment (PTA) of fraction of time during the dosing interval where the free drug concentration in plasma exceeds the MIC (Tf>MIC) for an MIC range of 0...

BACKGROUND: Current vancomycin dosing guidelines recommend targeting trough concentrations of 15-20 mg/L in complicated infections to avoid treatment failure and resistance. How to accomplish this in the intermittent hemodialysis (IHD) population has not been adequately described. A weight-based vancomycin dosing protocol for IHD patients was developed to provide standardization of vancomycin dosing for this patient population. Prior to implementation of this protocol, clinical pharmacists used their individual judgment for dosing and monitoring...

INTRODUCTION: Classic bladder exstrophy (BE) is a rare malformation of the genito-urinary tract affecting 1:50,000 to 1:100,000 live births. The surgical reconstruction of the BE-epispadias complex is challenging for the most experienced pediatric urologists, surgeons, and orthopedists. PURPOSE: To assess the success of staged reconstruction of the BE and long-term effects on the upper urinary tract, renal function, and continence. MATERIALS AND METHODS: This is retrospective study; between 1994 and 2013, 30 patients with BE have undergone stage 1 repair at the institute...

Introduction Patients with chronic kidney disease maintained on intermittent hemodialysis suffer from systemic chronic inflammation which is causally associated with high mortality. Inflammation mediators of 15-45 kDa range cannot be effectively removed by conventional dialysis membranes. In this study, we tested the influence of serum and dialysates obtained from patients maintained on High cut-off or High flux membranes on the inflammation profile of THP-1 monocytes. Methods THP-1 monocytes were treated with serum or dialysates obtained from patients maintained on High cut-off and High flux membranes within a randomized crossover pilot trial...

We describe the successful treatment of a pediatric transplant patient with simultaneous intermittent hemodialysis and therapeutic plasma exchange (TPE). The patient presented with kidney graft failure. He had life threatening electrolyte disturbances and fluid overload due to antibody-mediated rejection. Therefore, he was in need of both emergent kidney replacement therapy and TPE. Both extracorporeal circuits were set up, established, and maintained safely and effectively without difficulty or alarms. Running intermittent hemodialysis and TPE simultaneously significantly reduced therapy time, allowed both needed therapies priority, and provided a superior pediatric patient experience in an acute situation...

Pregnancy outcomes in patients with end-stage renal disease (ESRD) on dialysis are improving. Recent literature supports intensive hemodialysis (HD) as the modality of choice during pregnancy in ESRD. We report the successful delivery of a healthy infant at full term in a patient with ESRD by supplementing peritoneal dialysis (PD) with intermittent HD to achieve adequate dialysis intensity.

REVIEW
Daniel Kraus, Christoph Wanner
Critically ill patients who are treated in an intensive care unit are at increased risk of developing acute renal failure. Every episode of renal failure decreases life expectancy. However, acute renal failure is no longer an immediate cause of death because renal function can be substituted medically and mechanically, by the use of renal replacement therapy. Hemodialysis and hemofiltration are the 2 fundamental modalities of renal replacement therapy and may be performed intermittently or continuously. The decision for one particular therapy has to be made for each patient individually...
