Hemoperfusion in Trauma
Contrib Nephrol. 2023 Jun 1;200:1-11. doi: 10.1159/000527570. Online ahead of print.ABSTRACTMajor trauma care has seen significant improvements in early mortality, reflecting improvements in prehospital techniques for hemorrhage control and speed of access to specialized trauma centers. However, many patients then go on to die in the intensive care unit (ICU), and improvements in immediate trauma care are presenting intensivists with greater numbers of severely injured patients who might previously have died shortly after injury. It is theorized that, despite initial survival, these patients deteriorate due to massive rele...

Rationale for Adsorption in Extracorporeal Blood Purification
Contrib Nephrol. 2023 Jun 1;200:1-11. doi: 10.1159/000527707. Online ahead of print.ABSTRACTA strong rationale supports the development of adsorption-based extracorporeal blood purification in conditions such as sepsis, acute kidney disease, uremia, and acute liver failure. The retention of compounds as a consequence of acute or chronic organ dysfunction might have detrimental effects. When a causative effect of an accumulated compound in a pathogenic condition is demonstrated, a rationale for the removal of this solute is also established. Adsorption is a mass transfer mechanism in which a solute chemically interacts with...

Hemoperfusion in Cardiac Surgery and ECMO
Contrib Nephrol. 2023 Jun 1;200:1-12. doi: 10.1159/000527338. Online ahead of print.ABSTRACTExtracorporeal circulation (ECC) such as cardiopulmonary bypass or extracorporeal membrane oxygenation (ECMO) may induce a complex activation of the immune system. To date, strategies to mitigate this activation have failed to translate into meaningful improvement of clinical outcomes. Hemoperfusion is a blood purification technique, which relies on mass separation by a solid agent (hemoadsorption). It can be performed by adding a cartridge filled with adsorptive sorbent in the extracorporeal circuit. These devices have the theoreti...

Monitoring Treatment, Risks and Side Effects
Contrib Nephrol. 2023 Jun 1;200:1-9. doi: 10.1159/000527344. Online ahead of print.ABSTRACTInflammation plays a key role in the pathophysiology of organ dysfunction in the critically ill patients and is triggered by an overwhelming host response resulting in the overproduction of various cytokines. Regaining immune homeostasis over the dysregulated immune response through broad removal of cytokines using extracorporeal blood purification therapies has recently gained increasing attention. Nonetheless, many questions remain regarding the appropriate monitoring treatment, its potential risks, and side effects. The CytoSorb b...

Hemoperfusion in COVID-19
Contrib Nephrol. 2023 Jun 1;200:1-9. doi: 10.1159/000527583. Online ahead of print.ABSTRACTThe severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused the global emergency outbreak disease that devastatingly affected world public health and the economy. The pathogenesis of severe SARS-CoV-2 infection in humans has been linked to a strong immunological response that leads to a hyperinflammatory state, or "cytokine storm," which is a sepsis-like state resulting in capillary leakage, microvascular and macrovascular thrombosis, and multiple organ destruction. In recent years, there have been several case series...

Hemoperfusion: Indications, Dose, Prescription
Contrib Nephrol. 2023 Jun 1;200:1-10. doi: 10.1159/000529294. Online ahead of print.ABSTRACTRecent advances in the development of sorbent materials have enabled the development of hemoperfusion (HP). However, HP dose and prescription are not standardized and there is no consensus in clinical practice guidelines. Adequate prescription and modality are of utmost importance to ensure HP effectiveness. Although the main indication of CytoSorb®, HA330/380, polymyxin B, and Seraph® is sepsis, these devices may be beneficial in many other situations such as liver failure, rhabdomyolysis, pancreatitis, cardiopulmonary bypass, ex...

Extracorporeal Techniques Based on Adsorption: Nomenclature, Hardware, and Circuit Design
Contrib Nephrol. 2023 Jun 1;200:1-8. doi: 10.1159/000529313. Online ahead of print.ABSTRACTSorbents have been utilized in the past for intoxication and poisoning, but their spectrum of clinical application is now expanding. Hemoadsorption (HA) is still indicated for toxin and poison removal, but other molecules are considered appropriate targets for this blood purification modality. HA combined with hemodialysis (HA + HD) has been proposed for end-stage kidney disease patients to remove molecules that are not easily removed by classic HD or hemodiafiltration. More recently, a rationale for the use of sorbents in critical i...

Bilirubin Adsorption with DPMAS: Mechanism of Action and Efficacy of Anion Exchange Resin
Contrib Nephrol. 2023 Jun 1;200:1-9. doi: 10.1159/000526729. Online ahead of print.ABSTRACTAcute liver failure and acute-on-chronic liver failure are conditions in which the loss of metabolic function of the liver leads to the accumulation of several toxins such as bilirubin. Patients with sepsis or multiple organ dysfunction syndrome have a greater risk of developing liver failure, and hyperbilirubinemia is associated with poor prognosis. Bilirubin removal may not only alleviate signs and symptoms of liver dysfunction but also act as an index of removal of albumin-bound toxins. Conjugated and unconjugated bilirubin, due t...

Clinical Applications of Adsorption: The New Era of Jafron Sorbents
Contrib Nephrol. 2023 Jun 1;200:1-7. doi: 10.1159/000529845. Online ahead of print.ABSTRACTThe Jafron series of sorbent cartridges provides a comprehensive array of coated, highly biocompatible sorbent beads made of styrene-divinylbenzene copolymers. Such beads carry a mean diameter of 0.8 mm with a range from 0.60 to 1.18 mm. The maximal pore size of these coated beads and the volume of the cartridge vary according to the type of cartridge ranging between 50 Da and 60 kDa. The sorbents, the size of the cartridge, the volume of sorbent, and the pore size (which reaches 60 kDa with the HA330 cartridge) aim to take advantage...

Combined Hemoperfusion-Hemodialysis in End-Stage Renal Disease Patients
Contrib Nephrol. 2023 Jun 1;200:1-5. doi: 10.1159/000527953. Online ahead of print.ABSTRACTDespite advances in dialysis technology, a high level of morbidity and mortality is still present in end-stage renal disease patients undergoing maintenance dialysis. This has been in great part correlated with accumulation of uremic toxins that cannot be adequately removed by classic dialysis membranes and techniques. Improvements have been made in enhancing both membrane permeability and convection rates as in the case for expanded hemodialysis (HD) and hemodiafiltration, but these techniques still present limitations or cannot be ...
