AIM: The objective of this population pharmacokinetic (PK) analysis was to provide guidance for the dosing interval of daptomycin in patients undergoing continuous renal replacement therapy (CRRT). METHODS: A previously published population PK model for daptomycin was updated with data from patients undergoing continuous veno-venous haemodialysis (CVVHD; n = 9) and continuous veno-venous haemodiafiltration (CVVHDF; n = 8). Model-based simulations were performed to compare the 24 h AUC, Cmax and Cmin of daptomycin following various dosing regimens (4, 6, 8, 10, and 12 mg kg(-1) every [Q] 24 h and Q48 h), with the safety and efficacy exposure references for Staphylococcus aureus bacteraemia/right-sided infective endocarditis...

BACKGROUND: Hemodialysis with high cut-off continuous veno-venous hemodialyzer (HCO-CVVHD) removes mediators of organ dysfunction during sepsis. This study assessed the clinical effects of HCO-CVVHD as compared to high-flux (HF) membranes during gram-negative sepsis. METHODS: Intensive care unit (ICU), septic patients treated with HCO-CVVHD or HF-CVVHDF for AKI were retrospectively observed (January 2013-December 2014). Mechanical ventilation, vasopressors' requirements, ICU length of stay (LOS) and ICU in-hospital mortality were compared between groups...

BACKGROUND: The CARdiorenal PEDIatric EMergency (CARPEDIEM) machine was originally designed to perform only continuous venovenous hemofiltration (CVVH) in neonatal and pediatric patients. In some cases, adequate convective clearance may not be reached because of a limited blood flow. In such conditions, the application of diffusive clearance [continuous venovenous hemodialysis (CVVHD)] would help optimize blood purification. In this study, the CARPEDIEM™ machine was modified to enable the circulation of dialysis through the filter allowing testing of the performance of CARPEDIEM™ machine in CVVHD...

Extracorporeal modalities for the removal of drugs and toxins are indicated for the treatment of overdoses and intoxications. Well-established modalities include hemodialysis (HD), high-flux HD (HfD), and charcoal hemoperfusion (HP). Recently, there have been increasing reports on the use of continuous renal replacement therapy (CRRT), such as continuous veno-venous hemodialysis (CVVHD), continuous veno-venous hemofiltration (CVVH) or CVVH combined with dialysis (CVVHDF). In the present article, we will discuss the various factors that determine the clearance of drugs and toxins and accordingly, we will propose that with few exceptions, CRRT does not have a role in the routine management of intoxications...

BACKGROUND: Continuous venovenous hemodialysis (CVVHD) may generate microemboli that cross the pulmonary circulation and reach the brain. The aim of the present study was to quantify (load per time interval) and qualify (gaseous vs. solid) cerebral microemboli (CME), detected as high-intensity transient signals, using transcranial Doppler ultrasound. MATERIALS AND METHODS: Twenty intensive care unit (ICU group) patients requiring CVVHD were examined. CME were recorded in both middle cerebral arteries for 30 minutes during CVVHD and a CVVHD-free interval...

BACKGROUND: Dialysate fluid connection to the membrane in continuous dialysis may affect solute clearance. Although circuit connections are routinely made counter-current to blood flow in intermittent dialysis, no study has assessed the effect of this dialysate fluid flow direction on removal of small solutes creatinine and urea during treatment using continuous veno-venous haemodialysis (CVVHD). AIMS: To assess if dialysate flow direction during CVVHD affects small solute removal...

Continuous venovenous haemodialysis with high cut-off membrane (HCO-CVVHD) is often used in critically ill septic patients with acute kidney injury (AKI) to sustain renal function and to remove circulating inflammatory mediators. The aim of this study was to analyse the extracorporeal removal of linezolid and related alterations in pharmacokinetic/pharmacodynamic (PK/PD) parameters during HCO-CVVHD. Three critically ill septic patients with AKI, treated with linezolid and HCO-CVVHD, were prospectively observed...

There are clinical situations where rapid elimination of dabigatran is beneficial. Intermittent hemodialysis (IHD) removes dabigatran effectively but is not always available and requires a hemodynamically stable patient. We therefore investigated the continuous venovenous hemodialysis (CVVHD) technique for its potency in the elimination of dabigatran. Based on pharmacometric characterization of dabigatran in IHD, we simulated a broad range of dialysis settings for CVVHD and then applied the model to specific clinical situations...

Oral methanol intoxication is common, but dermal intoxication is rare. We report a previously healthy 19-month-old female infant admitted to the emergency department (ED) with vomiting and tonic-clonic seizure. On physical examination, she was comatose and presented signs of decompensated shock with Kussmaul breathing. Her left thigh was edematous, with purple coloration. Methanol intoxication was suspected due to high anion gap metabolic acidosis (pH, 6.89; HCO3, <3 meq/L) and exposure to spirit-soaked bandages (%96 methanol) for 24 hours and 3 days...

The pharmacokinetics of meropenem have not yet been examined in Japanese patients receiving Continuous venovenous hemodialysis (CVVHD). The aim of this clinical investigation was to determine the pharmacokinetic parameters of meropenem in critically ill patients receiving CVVHD in order to estimate dosing regimens for the patient population in Japan. The values of pharmacokinetic parameters were 17.5 ± 5.6 l for V1, 1.27 ± 0.38 h(-1) for K12, 0.71 ± 0.40 h(-1) for K21 and 0.17 ± 0.02 h(-1) for K10. Based on these mean parameters (V1, K12, K21 and K10), time above MIC (T > MIC) values were estimated at different MICs using various meropenem regimens...

Dabigatran, a direct thrombin inhibitor, is increasingly used for stroke prevention in patients with non-valvular atrial fibrillation. Dabigatran has a stable pharmacokinetic profile with minimum drug interactions, and requires no routine laboratory evaluation to measure level of anticoagulation. This provides a huge advantage over warfarin, and has the potential to improve patient compliance. The disadvantages of dabigatran are the lack of a reversal agent to counter dabigatran-related bleeding and the absence of a widely available laboratory test that can quantify the extent of coagulopathy in dabigatran overdose...

BACKGROUND: Differentiation syndrome is a life-threatening complication of therapy that is carried out with agents used for acute promyelocytic leukemia. Its physiopathology comprehends the production of inflammatory mediators by differentiating granulocytes, endothelial and alveolar cells due to stimulation by all-trans retinoic acid and leading to sustained systemic inflammation. METHODS: Treatment with high cut-off continuous veno-venous hemodialysis (HCO-CVVHD) was performed to reduce the circulating mediators of systemic inflammation...

PURPOSE: Early clinical signs of heparin induced thrombocytopenia (HIT) are nonspecific and include a sudden drop in the number of platelets as well as formation of arterial and venous thromboses. Regional citrate anticoagulation (RCA) is increasingly used as a very effective modality to prevent filter clotting during renal replacement therapy (RRT). We report the first case where repeated premature filter clotting despite RCA indicated a manifestation of HIT. MATERIALS AND METHODS: A 71-year old woman admitted to the ICU for a compartment syndrome of the leg developed septic shock with acute kidney injury requiring continuous veno-venous hemodialysis (CVVHD)...
