BACKGROUND: Idiopathic hyperammonemia syndrome (IHS) is an uncommon, often deadly complication of solid organ transplantation. IHS cases in solid organ transplantation seem to occur predominantly in lung transplant (LTx) recipients. However to the best of our knowledge the occurrence of IHS has not been systematically evaluated. We set out to identify all reported cases of IHS following non-liver solid organ transplantations. METHODS: Retrospective review of our institutional experience and systematic review of the literature...

PURPOSE: During an outbreak of mass methanol poisoning in the Czech Republic in 2012-2014, we compared the total hospital costs and one-year medical costs in the patients treated with different antidotes (fomepizole versus ethanol) and modalities of hemodialysis (intermittent hemodialysis, IHD, versus continuous renal replacement therapy, CRRT). METHODS: Cross-sectional study in 106 patients with confirmed diagnosis treated in 30 ICU settings. For each patient, the following data were analyzed: admission laboratory data, GCS, PSS, ICU length of stay, organ failures, treatment, outcome, and total hospital costs...

Patients with end-stage renal disease undergo renal transplant, peritoneal dialysis, or intermittent hemodialysis for renal replacement therapy. For hemodialysis, native fistulas or grafts are preferred but hemodialysis catheters are often necessary. Per KDOQI, the right jugular vein is the preferred vessel of access for these catheters. However, in patients with long-standing end-stage renal disease vein thrombosis, stenosis and occlusion occurs. In these patients with end-stage vascular access, unconventional routes of placement of dialysis catheters are needed...

INTRODUCTION: Adequate hemodialysis directly improves health. Puncturing an arteriovenous fistula (AVF) and the amount of blood recirculation greatly affect the quality of dialysis. Few studies have assessed the method to cannulate a fistula and its influence on efficiency of hemodialysis. METHODS: This prospective pilot study included 14 patients with end-stage renal failure receiving regular intermittent hemodialysis. Patients received three consecutive treatments with both needles directed upstream then three consecutive treatments with the venous needle directed upstream and the arterial needle directed downstream...

Continuous renal replacement therapy (CRRT) is commonly used to support critically ill patients with acute kidney injury or chronic renal disease whose condition is too unstable for them to tolerate intermittent hemodialysis. Current publications related to CRRT programs in the United States and Canada note key themes related to the development and maintenance of CRRT training programs. A successful CRRT training program should consider and incorporate adult learning principles whenever possible. A variety of teaching methods to deliver information to nurses, including online learning modules, didactic lecture, return demonstration, and high-fidelity patient simulation are key to training programs for this high-risk complex therapy...

Continuous renal replacement therapy (CRRT) was introduced more than 40 years ago as a renal support option for critically ill patients who had contraindications to intermittent hemodialysis and peritoneal dialysis. Despite being the most common renal support therapy used in intensive care units today, the tremendous variability in CRRT management challenges the interpretation of findings from CRRT outcome studies. The lack of standardization in practice and training of clinicians along with the high risk of CRRT-related adverse events has been the impetus for the recent expert consensus work on identifying quality indicators for CRRT programs...

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...

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...
