Valproic acid (VPA) is a wide-ranging anti-epileptic medication that primarily affects bipolar disorder, mania, and migraine. The leading causes of mortality associated with acute poisoning from VPA are nervous system toxicity, drug-induced shock due to encephalopathy from hyperammonemia, as well as acute liver and kidney failure, and respiratory depression that contribute to hemodynamic instability. Treatment of acute VPA poisoning primarily involves in vitro elimination methods, including hemoperfusion (HP), hemodialysis, and hemofiltration, as well as drug remedies such as L-carnitine and meropenem...

During the last decades, various strategies have been optimized to enhance clearance of a variable spectrum of retained molecules to ensure hemodynamic tolerance to fluid removal and improve long-term survival in patients affected by end-stage kidney disease. Treatment effects are the result of the interaction of individual patient characteristics with device characteristics and treatment prescription. Historically, the nephrology community aimed to provide adequate treatment, along with the best possible quality of life and outcomes...

OBJECTIVES: Patients with sepsis are at significant risk for multiple organ dysfunction, including the lungs and kidneys. To manage the morbidity associated with kidney impairment, continuous renal replacement therapy (CRRT) may be required. The extent of anakinra pharmacokinetics in CRRT remains unknown. The objectives of this study were to investigate the anakinra-circuit interaction and quantify the rate of removal from plasma. DESIGN: The anakinra-circuit interaction was evaluated using a closed-loop ex vivo CRRT circuit...

Presepsin, which is used as a biomarker for sepsis, is thought to be removed by dialysis, but the actual removal properties of dialysis are unknown. We investigated the presepsin removal properties of continuous hemodiafiltration using the high concentration of presepsin from human plasma drained by plasma exchange. Each solution in plasma exchange was connected to a continuous hemodiafiltration blood circuit and circulated at 4 conditions. The results show that presepsin was confirmed to be removed more efficiently in hemofiltration than in hemodialysis...

Endogenous peptide inhibitor for CXCR4 (EPI-X4) is a CXCR4 antagonist with potential for cancer therapy. It is a processed fragment of serum albumin from the hemofiltrate of dialysis patients. This study reports the efficacy of fifteen EPI-X4 derivatives in pancreatic cancer and lymphoma models. In vitro, the peptides were investigated for antiproliferation (cytotoxicity) by MTT assay. The mRNA expression for CXCR4 and CXCL12 was determined by RT-PCR, chip array and RNA sequencing. Chip array analysis yielded 634 genes associated with CXCR4/CXCL12 signaling...

Hypertriglyceridemia-induced acute pancreatitis (HTG-AP) is characterized by a violent cytokine storm-driven inflammation and is associated with a predisposition to severe disease. The treatment strategy for HTG-AP consists mainly of conventional symptomatic and lipid-lowering treatments. For early-stage HTG-AP, blood purification (BP) can rapidly and effectively reduce serum triglyceride and inflammatory cytokine levels, block the development of systemic inflammatory response syndrome, and improve patient outcomes...

BACKGROUND AND OBJECTIVES: The mortality rate for people with brain injuries is increased when hypernatremia is present. Patients with severe hypernatremia, who have a significant short-term mortality rate, were shown to benefit from continuous venovenous hemofiltration (CVVH), which has been indicated to be successful. Exploring the risk factors for short-term mortality in brain injury patients who underwent CVVH and had severe hypernatremia was the aim of the current study. MATERIALS AND METHODS: Retrospective screening was performed on patients with brain injuries who underwent CVVH at Xijing Hospital between 1 December 2010 and 31 December 2021 and who have a diagnosis of severe hypernatremia...

OBJECTIVE: To evaluate the clinical efficacy and safety of fractionated plasma separation and adsorption integrated with continuous veno-venous hemofiltration (FPSA-CVVH) treatment in patients with acute liver failure (ALF). METHODS: In this retrospective study, we enrolled patients with ALF (serum total bilirubin >10 mg/dL or Model for End-Stage Liver Disease [MELD] Score >18) hospitalized between August 2017 and August 2022. All patients had at least two sessions of FPSA-CVVH...

To investigate the efficacy and safety of continuous blood purification (CBP) in neonates with septic shock and acute kidney injury (AKI). This retrospective study was conducted at two tertiary care children's hospitals between January 2015 and May 2022. A total of 26 neonates with septic shock and AKI were included in this study, with a mortality rate of 50%. Fourteen neonates (53.8%) received continuous veno-venous hemodiafiltration, and 12 (46.2%) received continuous veno-venous hemofiltration. Compared with the indices before CBP, urine output increased 12 h after CBP initiation (P = 0...

BACKGROUND: During cirrhosis, the liver is impaired and unable to synthesize and clear thrombopoietin properly. At the same time, the spleen assumes the function of hemofiltration and storage due to liver dysfunction, resulting in hypersplenism and excessive removal of platelets in the spleen, further reducing platelet count. When liver function is decompensated in cirrhotic patients, the decrease of thrombopoietin (TPO) synthesis is the main reason for the decrease of new platelet production...

INTRODUCTION: The TKM-101 is a new hemofiltration column packed with a polymer alloy membrane consisting of polyethersulfone, polyvinylpyrrolidone, and sulfonated poly (arylene ether) copolymers. We examined the ability of the TKM-101 column to remove cytokines and humoral mediators from blood in vitro and the effects of extracorporeal treatment with the TKM-101 column on the mortality rate and inflammatory responses to endotoxic shock in vivo. METHODS: In vitro and in vivo laboratory investigations were conducted...

INTRODUCTION: The ideal modality choice and dialysis prescription during the first renal replacement therapy (RRT) session remains unclear. We conducted a pilot study to determine the safety risk for hemodialysis (HD) versus hemofiltration (HF) and its relationship with neurocognitive assessment on incident RRT patients. METHODS: Twenty-four incident RRT patients were included. Patients were randomized to the conventional HD group or post-dilution HF group. Minimental State Examination (MMSE) and Montreal Cognitive Assessment (MOCA) tests were applied in all patients before and after session and brain MRI was performed in 7 patients from the conventional HD group and 8 patients from the post-dilution HF group before and after the intervention...

OBJECTIVES: The goal of this study was to investigate the clinical value of emergent triglyceride (TG)-lowering therapies for hyperlipidemic acute pancreatitis (HLAP). METHODS: 126 HLAP patients were assigned randomly to receive either conventional treatment (CT), normal saline (NS) alone, or continuous veno-venous hemofiltration (CVVH) as an intensive TG-lowering therapy. TG levels, clinical outcomes, and inflammatory biomarkers were compared among the three groups...

Thyroid storm (TS) is a rare and fatal endocrine emergency that occurs due to undiagnosed and inadequately treated hyperthyroidism after stressful conditions in patients with thyroid disorders. The objective of this systematic scoping review was to better understand the pathophysiology of TS and its complications, in terms of myocardial affection, tachyarrhythmia, and cardiogenic shock. In addition, we explored the pharmacological, mechanical, and surgical treatments for TS. We also evaluated the outcomes of TS according to sex and cardiac involvement...
