Hemoperfusion using metal ion affinity adsorbent is a promising method to remove human testosterone in plasma. Due to the leakage of metal ion from the adsorbents, there is no metal ion affinity adsorbent for hemoperfusion. In this study, chitosan was used to coat the adsorbent for preventing the leakage of Zn2+ loaded. Meanwhile, freeze-drying method was used to enhance adsorption capacity of Zn2+ -loaded cellulose beads for testosterone. The results indicate that after the adsorbent was coated by 0.02% chitosan solution, the highest adsorption percentage reached 48%, during adsorption, the Zn2+ concentration in plasma did not increase; the adsorption capacity of the adsorbent can be significantly enhanced by freeze-drying...

For continuous renal replacement therapy (CRRT), the extracorporeal filter provides solute depuration, fluid removal, and control of electrolyte and acid-base balance in critically ill patients with acute kidney injury (AKI). The membranes comprising CRRT filters are almost exclusively based on hollow fiber designs and, while adapted from the chronic hemodialysis field, have features that are specific to the requirements of CRRT nevertheless. In addition, these devices have evolved through the 40 years of CRRT in response to changes in clinical practice and the desire to extend the solute removal spectrum...

INTRODUCTION: So far, only heparin-based anticoagulation has been proposed during polymyxin-B hemoperfusion. However, postsurgical septic patients can be at high risk of bleeding due to either surgical complications or septic coagulation derangement. Consequently, heparin should not represent in some cases the anticoagulation regimen of choice in this type of patients. METHODS AND RESULTS: We present a case series of four postsurgical septic patients treated with polymyxin-B hemoperfusion using regional citrate anticoagulation...

Idiopathic pulmonary fibrosis (IPF) is a fibrotic lung disease characterized by progressive loss of lung function and poor prognosis. The so-called acute exacerbation of IPF (AE-IPF) may lead to severe hypoxemia requiring mechanical ventilation in the intensive care unit (ICU). AE-IPF shares several pathophysiological features with acute respiratory distress syndrome (ARDS), a very severe condition commonly treated in this setting.A review of the literature has been conducted to underline similarities and differences in the management of patients with AE-IPF and ARDS...

BACKGROUND: Sepsis caused by complicated intra-abdominal infection is associated with high mortality. Loss of endothelial barrier integrity, inflammation, and impaired cellular oxygen have been shown to be primary contributors to sepsis. To date, little is known regarding the pathway for the mobilization of endothelial progenitor cells (EPCs) from the bone marrow in sepsis whereas stromal-cell-derived factor 1a (SDF-1a) and hypoxia inducible factor 1 (HIF-1) seem to have a role in the EPC response to hypoxic microenvironments...

BACKGROUND: Descending necrotizing mediastinitis is a common and progressive polymicrobial infection involving the neck and chest with a high death rate (10 to 40%). From a microbiological point of view, descending necrotizing mediastinitis is sustained by Gram-positive bacteria (43-62%), anaerobes (46-78%), and, rarely, Gram-negative bacteria. Data collected during the Antibiotic Resistance-Istituto Superiore di Sanità project confirmed that Italy is positioned among the countries with the highest levels of resistance in most pathogenic species under surveillance...

Hyperbilirubinemia, caused by the disorders in bilirubin metabolism, could result in neurotoxicity, permanent brain damage and even death. As one of effective bilirubin removal technologies from blood, hemoperfusion had attracted much attention. However, the development of bilirubin adsorbents used in hemoperfusion with excellent adsorption capacity and hemocompatibility still faced great challenges. In this work, the cationic hydrogel was prepared by the photo-initiated polymerization of biodegradable poly(ester amine) (PEA) based on PLLA and low molecular weight PEI1800...

BACKGROUND: The definition of sepsis was updated to sepsis-3 in February 2016. Currently, direct hemoperfusion therapy using the polymyxin B-immobilized fiber cartridge (PMX-DHP) is widely performed to treat sepsis and septic shock. However, the prognostic factors of PMX-DHPs in patients with sepsis using the new definition are unclear. We retrospectively assessed prognostic factors in patients who had received PMX-DHP therapy for sepsis and septic shock. METHODS: We included 71 patients with severe infection who underwent PMX-DHP treatment from January 2006 to August 2015 in this study...
