A 67-year-old woman exhibited chilblain-like erythema on the bilateral auricles, erythema with hyperkeratosis on the sides of fingers and the bilateral elbows, and erythema on the extensor/flexor sides of the finger joints and the iliac regions. Fine crackles were audible on the dorsal side of the bilateral lower lung regions. We diagnosed clinically amyopathic dermatomyositis accompanied by rapidly progressive interstitial pneumonia. While we initiated immunosuppressive therapy, the respiratory failure showed no responses...

Limitations imposed by the characteristics of some solutes and the structure of dialysis membranes have spurred new interest in the use of mechanisms beyond diffusion and convection for extracorporeal solute removal. Sorbents have been utilized for more than 50 years in extracorporeal blood treatments for specific purposes, and better understanding of their basic aspects may further expand the potential for their clinical application. In this chapter, the basic principles applying to sorbents are discussed, including composition and structure, along with the fundamental mechanisms of solute removal...

INTRODUCTION: Infective endocarditis is a serious disease condition. Depending on the causative microorganism and clinical symptoms, cardiac surgery and valve replacement may be needed, posing additional risks to patients who may simultaneously suffer from septic shock. The combination of surgery bacterial spreadout and artificial cardiopulmonary bypass (CPB) surfaces results in a release of key inflammatory mediators leading to an overshooting systemic hyperinflammatory state frequently associated with compromised hemodynamic and organ function...

Activated carbon has been widely used in hemoperfusion treatments. However, its performance has been significantly compromised by their poor hemocompatibility. In this work, we developed a novel antifouling adsorbent based on zwitterionic poly-carboxybetaine (PCB) hydrogel and powdered activated carbon (PAC) to improve hemocompatibility. We found this new adsorbent (PCB-PAC) was highly stable with negligible leakage of activated carbon debris. It could efficiently resist protein adsorption and avoid any hemolysis effect...

BACKGROUND: Endotoxins contribute to systemic inflammatory response and microcirculatory dysfunctions under conditions of sepsis. Polymyxin B hemoperfusion (PMX-HP) is used to remove circulating endotoxins and improve clinical outcomes. This study aims to investigate the effect of PMX-HP on microcirculation in septic pigs. MATERIALS AND METHODS: By using a septic pig model, we tested the hypothesis that PMX-HP can correct intestinal microcirculation, tissue oxygenation saturation, and histopathologic alterations...

Carbon-based nanomaterials have recently attracted tremendous attention in adsorption, separation and biological fields. However, such modification is not always straightforward when the surface is not chemically reactive. Given this reason, most carbon materials modification processes employ reactive linkers or coupling agents, which are complicated and time-consuming. Herein, we report on a dopamine-polyethyleneimine (PEI) coating strategy to fabricate micrometer-sized magnetic carbon fiber (MSMCF)-based extracorporeal blood-cleansing sorbent for hemoperfusion...

A 21-year-old man ingested 75g of pure caffeine, in an attempt to commit suicide. This represents 7.5 times the minimal lethal dose. Caffeine, 1,3,7-trimethylxanthine, is the most widely consumed psychoactive compound worldwide. It is mostly found in coffee, tea, energizing drinks and in some drugs. However, it has become really easy to obtain pure caffeine (powder or tablets) on the Internet. Mechanisms of action are dose-dependent. When caffeine overdosing occurs, neurologic, cardiovascular and renal systems are mainly affected...

OBJECTIVE: Several studies have reported a survival benefit for polymyxin B hemoperfusion treatment in patients with severe sepsis and septic shock. However, recently, a propensity-matched analysis and a randomized controlled trial reported no survival benefit for polymyxin B hemoperfusion treatment. We performed an up-to-date meta-analysis to determine the effect of polymyxin B hemoperfusion treatment on mortality in patients with severe sepsis and septic shock. DATA SOURCES: PubMed, Embase, and Cochrane Library were searched from inception to May 2016...

BACKGROUND AND OBJECTIVE: Acute exacerbation of idiopathic pulmonary fibrosis (AE-IPF) is recognized as an important cause of mortality. AE has also been reported in patients with other interstitial lung diseases such as idiopathic non-specific interstitial pneumonia (NSIP) and interstitial pneumonia associated with collagen vascular disease (CVD). Current therapies such as high-dose corticosteroid with immunosuppressive agents have provided little benefit for AE. Direct hemoperfusion (DHP) with a polymyxin B-immobilized fibre column (PMX) was originally developed for the treatment of endotoxaemia...

Septic shock-associated mortality in intensive care units (ICUs) remains high, with reported rates ranging 30-50%. In particular, Gram-negative bacilli (GNB), which induce significant inflammation and consequent multiple organ failure, are the etiological bacterial agent in 40% of severe sepsis cases. Hemoperfusion using polymyxin B-immobilized fiber (PMX), which adsorbs endotoxin, is expected to reduce the inflammatory sepsis cascade due to GNB. However, the clinical efficacy of this treatment has not yet been demonstrated...

Background: Extracorporeal treatments (ECTRs) are used for different conditions, including replacement of organ function and poisoning. Current recommendations for ECTRs in various poisonings suggest that intermittent haemodialysis (IHD) is the most efficient technique. However, the practicality of these recommendations is poorly defined in view of limited information on availability and cost worldwide. Methods: A survey invitation to an Internet-based questionnaire was emailed between January 2014 and March 2015 to members of international societies to determine the availability, time to initiation and cost of ECTRs (including filters, dialysate, catheter, anticoagulant and nursing/physician salary)...

BACKGROUND: Ventilation with low tidal volume and airway pressure results in a survival benefit in ARDS patients. Previous research suggests that avoiding mechanical ventilation altogether may be beneficial in some cases of respiratory failure. Our hypothesis was that low flow veno-venous extracorporeal CO2 removal (ECCO2R) enables maintenance of a lung protective ventilation strategy or awake spontaneous ventilation despite severe hypercapnic respiratory failure (HRF). METHODS: Twenty patients with HRF were investigated while mechanically ventilated (n=14) or breathing spontaneously close to respiratory exhaustion (n=6)...
