Endotoxin adsorption therapy by polymyxin B-immobilized fiber column direct hemoperfusion (PMX-DHP) has been used for the treatment of septic shock patients. Endotoxin, an outer membrane component of Gram-negative bacteria, plays an important role in the pathogenesis of septic shock. Endotoxin triggers a signaling cascade for leukocytes, macrophage, and endothelial cells to secrete various mediators including cytokines and nitric oxide, leading to septic shock and multiple organ dysfunction syndrome.

Background: Neutrophil gelatinase-associated lipocalin (NGAL) is a diagnostic marker for acute kidney injury (AKI). NGAL expression is highly induced not only in kidney injury but also in bacterial infection, inflammation, and cancer. The factors regulating NGAL expression are proinflammatory cytokines, and plasma NGAL levels have been increased in septic shock.

Background: Weaning from prolonged mechanical ventilation is extremely difficult in tracheostomized patients with restrictive pulmonary dysfunction. High-flow oxygen via tracheostomy supplies heated and humidified oxygen gas at > 10 L/minute. However, little has been reported on the use of high-flow oxygen via tracheostomy during weaning from ventilators in patients with restrictive pulmonary dysfunction.

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.

Article Synopsis
  • Direct hemoperfusion with a polymyxin B-immobilized column (PMX-DHP) is being studied for its potential to treat septic shock and protect against acute kidney injury, though its exact mechanisms are not fully understood.
  • In an experiment with anesthetized rats that underwent cecal ligation and puncture, PMX-DHP was shown to maintain blood stability and significantly lower harmful plasma markers related to kidney damage compared to a control group.
  • Results indicated that PMX-DHP could protect kidney cells by reducing apoptosis and inhibiting key signaling pathways involved in inflammation and cell death, suggesting it could be a beneficial treatment during septic shock.

Background: Renal ischemia-reperfusion injury (IRI) is a common cause of acute kidney injury and a frequent occurrence in critically ill patients. Renal IRI releases proinflammatory cytokines within the kidney that induce crosstalk between the kidney and other organ systems. Atrial natriuretic peptide (ANP) has anti-inflammatory as well as natriuretic effects and serves important functions as a regulator of blood pressure, fluid homeostasis, and inflammation.
