[Observation on the efficacy of continuous veno-venous hemodia-filtration combined with hemoperfusion HA380 in the treatment of 15 cases of heat stroke with multiple organ dysfunction syndrome].

OBJECTIVE: To investigate the clinical efficacy of continuous veno-venous hemodia-filtration (CVVHDF) combined with hemoperfusion (HP) HA380 in the treatment of heat stroke patients with multiple organ dysfunction syndrome (MODS). METHODS: A retrospective and observational study was conducted. A total of 15 patients with heat stroke combined with MODS who were admitted to the department of intensive care unit (ICU) of Suizhou Central Hospital/Hubei University of Medicine from July to September 2022 were selected as the study objects. All 15 patients were treated with CVVHDF combined with HA380 based on the comprehensive management strategy for severe illness. Organ function indicators [including total bilirubin (TBil), aspartate aminotransferase (AST), creatine kinase (CK), lactate dehydrogenase (LDH), creatinine (Cr), cardiac troponin T (cTnT), myoglobin (Myo), MB isoenzyme of creatine kinase (CK-MB), sequential organ failure assessment (SOFA)] and inflammatory indicators [including white blood cell count (WBC), neutrophil count (NEU), C-reactive protein (CRP), procalcitonin (PCT), and interleukin-6 (IL-6)] were collected. The improvements of the above indexes at admission, after the first HP, after the second HP, after the third HP, and on the 5th day of treatment were compared. Combined with the clinical outcome of patients, the comprehensive efficacy of CVVHDF combined with HA380 in the treatment of severe heat radiation disease was evaluated. RESULTS: There were 10 males and 5 females among the 15 patients. The average age was (64.5±11.5) years old. There were 6 cases of classical heat stroke and 9 cases of exertional heat stroke. Glasgow coma scale (GCS) was 3-8 at admission; SOFA score was 9-17 within 12 hours after admission; acute physiology and chronic health evaluation II (APACHE II) was 25-45 within 24 hours after admission. After treatment, the IL-6 level and SOFA score gradually decreased, and there were significant differences in the decrease after the second HP compared to admission [IL-6 (ng/L): 48.37 (15.36, 113.03) vs. 221.90 (85.87, 425.90), SOFA: 8.3±3.3 vs. 11.1±2.4, both P < 0.05]. The PCT level reached its peak after the first HP [12.51 (6.07, 41.65) µg/L], and then gradually decreased, and the difference was statistically significant after the third HP [1.26 (0.82, 5.40) µg/L, P < 0.05]. Compared those at admission, Cr level significantly improved after the first HP (µmol/L: 66.94±25.57 vs. 110.80±31.13, P < 0.01), Myo significantly decreased after the second HP [µg/L: 490.90 (164.98, 768.05) vs. 3 000.00 (293.00, 3 000.00), P < 0.05], After the third HP, the CK level also showed significant improvement [U/L: 476.0 (413.0, 922.0) vs. 2 107.0 (729.0, 2 449.0), P < 0.05]. After CVVHDF combined with 3 times HP treatment, the patient's inflammatory response was gradually controlled and organ function gradually recovered. On the 5th day of the disease course, WBC, PCT and IL-6 levels were significantly improved compared to admission, and AST, CK, LDH, Cr, Myo, CK-MB, and SOFA score were significantly corrected compared with those on admission. The 24-hour survival rate of 15 patients was 86.67%, and the 24-hour, 7-day and 28-day survival rates were both as high as 73.33%. The average mechanical ventilation time of 11 surviving patients was (101.8±22.0) hours, the average continuous renal replacement therapy (CRRT) time was (58.8±11.0) hours, the average length of ICU stay was (6.3±1.0) days, and the average total hospitalization was (14.6±5.2) days. CONCLUSIONS: CVVHDF combined with HP HA380 in the treatment of heat stroke patients with MODS can effectively improve organ function and alleviate the inflammatory storm, which is an effective means to improve the rescue rate and reduce the mortality of severe heat stroke patients.

Assessment of triglyceride clearance of haemoperfusion from three cases of hypertriglyceridaemia-induced acute pancreatitis: a case series.

Rapid reduction of plasma triglycerides (TG) is believed to improve the outcome of pancreatitis in the context of hypertriglyceridaemia (HTG)-induced acute pancreatitis (HTG-AP). Previous studies have suggested that haemoperfusion (HP) with the Jafron cartridge series could be effective for reducing TG concentrations in patients with HTG-AP. However, the clearance capacity (CC) for TG removal has not been reported. This case series reports on data from three patients with HTG-AP who underwent HP with HA230 or HA330 cartridges. Blood samples were collected from both before and after the cartridge circuit every 30 min and the CC was calculated. Twelve pairs of blood samples were collected for each type of HP cartridge. The mean ± SD CC of the HA230 cartridge for TG removal in this case series was 0.009781 ± 1.117235 ml/min (95% confidence interval [CI], -0.7000762, 0.7196384 ml). The mean ± SD CC of the HA330 cartridge for TG removal in this case series was 0.344914 ± 1.412183 ml/min (95% CI, -0.5523448, 1.2421721 ml). Based on the findings of this small case series, special caution is advised when considering the use of the HA230 and HA330 cartridges for reducing blood TG concentration pending further conclusive evidence from larger studies.

Blood perfusion with polymyxin B immobilized columns in patients with COVID-19 requiring oxygen therapy.

Extracorporeal blood purification with polymyxin B immobilized fiber column direct hemoperfusion (PMX-DHP), is reported to be effective in treating COVID-19 pneumonitis with oxygen demand. This multicenter prospective study evaluated the efficacy and safety of PMX-DHP in oxygen-requiring patients with COVID-19 admitted between September 28, 2020, and March 31, 2022. The primary endpoint was the percentage of clinical improvement 15 days after treatment. The secondary endpoint was the percentage of worsened disease status. Data from the COVID-19 patient registry were used for the synthetic control group. The improvement rate on Day 15 did not differ between PMX-treated patients and controls; however, the deterioration rate was 0.38 times lower in the PMX-treated group, and the death rates on Day 29 were 0 and 11.1% in the PMX-treated and control groups, respectively. The PMX group showed a 0.73 times higher likelihood for reduced intensive care demand, as 16.7% of PMX-treated patients and 22.8% of controls worsened. After treatment blood oxygenation improved, urinary ß2-microglobulin and liver-type fatty acid-binding protein showed significant decreases, and IL-6 decreased once during treatment but did not persist. In this study, PMX treatment effectively prevented the worsening of COVID-19 pathology, accompanied by improved oxygenation. PMX treatment to remove activated cells may effectively improve patient outcomes.

[Two cases of pyridaben poisoning were successfully treated by blood purification].

Pyridaben is a broad-spectrum acaricide widely used in agriculture, accidental or self-administration of large doses of pyridaben can cause multiple organ failure in patients. Due to its damage to multiple organs and no specific antidote, the mortality rate is high. This paper reports two patients who took a large amount of pyridaben, developed severe metabolic acidosis, hyperlactatemia, toxic encephalopathy, and liver, kidney, heart and digestive tract damage. After timely gastric lavage, catharsis, organ support andblood purification treatment, the condition improved and discharged. It is expected to provide clinical ideas for the treatment of pyridaben poisoning.

An Evolutionary Review of Hemoperfusion Adsorbents: Materials, Preparation, Functionalization, and Outlook.

Accumulation of pathogenic factors in the blood may cause irreversible damage and may even be life-threatening. Hemoperfusion is an effective technique for eliminating pathogenic factors, which is widely used in the treatment of various diseases including liver failure, renal failure, sepsis, and others. Hemoperfusion adsorbents are crucial in this process as they specifically bind and remove the target pathogenic factors. This review describes the development of hemoperfusion adsorbents, detailing the different properties exhibited by inorganic materials, organic polymers, and new materials. Advances in natural and synthetic polymers and novel materials manufacturing techniques have driven the expansion of hemoperfusion adsorbents in clinical applications. Stimuli-responsive (smart responsive) adsorbents with controllable molecular binding properties have many promising and environmentally friendly biomedical applications. Knowledge gaps, future research directions, and prospects for hemoperfusion adsorbents are discussed.

TiO2/Polystyrene Nanocomposite Antibacterial Material as a Hemoperfusion Adsorbent for Efficient Bilirubin Removal and Prevention of Bacterial Infection.

The use of hemoperfusion adsorbents for the removal of bilirubin in patients with liver failure has become a critical treatment. However, the insufficient clearance of bilirubin and the possibility of bacterial infection during hemoperfusion limit the application. In this work, we designed a novel antibacterial bilirubin adsorbent (PSVT) through the suspension polymerization reaction between double-bond functionalized TiO2 nanoparticles and styrene. PSVT showed an excellent bilirubin adsorption ability and antibacterial performance, ensuring efficient clearance of bilirubin in liver failure patients during hemoperfusion and preventing bacterial infection. The experimental results indicated that TiO2 was uniformly dispersed in the microspheres, which improved the mesoporous structure and increased the specific surface area. Composite adsorbent PSVT showed an exceptional bilirubin adsorption capacity, with the maximum adsorption capacity reaching 24.3 mg/g. In addition, the introduction of TiO2 endowed PSVT with excellent antibacterial ability; the ultimate antibacterial rates against Escherichia coli and Staphylococcus aureus reached 97.31 and 96.47%, respectively. In summary, PSVT served as a novel antibacterial bilirubin adsorbent with excellent bilirubin clearance capacity and antibacterial performance, providing excellent application prospects for treating liver failure patients.

Removal of inflammatory factors and prognosis of patients with septic shock complicated with acute kidney injury by hemodiafiltration combined with HA330-II hemoperfusion.

INTRODUCTION: To explore the effect of CRRT using CVVHDF + HP on the removal of inflammatory mediators in patients with septic shock complicated with AKI. METHODS: A total of 20 patients between January 1, 2018, and December 31, 2021, were included. The patients were randomly divided into the treatment group (CVVHDF + HP) and the control group (CVVHDF). Changes in inflammatory factors, including IL-1ß, IL-6, IL-8, TNF-α, PCT, and CRP were compared. Other observed measures were also analyzed, for example, Lac, Scr, BUN, SOFA, and norepinephrine (NE) dosage. The clinical outcomes of both groups were followed up for 28 days. RESULTS: The IL-6 and PCT levels in the treatment group were significantly lower (p = 0.005, 0.007). Although the IL-1ß, TNFα, and CRP levels in the treatment group decreased, there were no statistical differences (p > 0.05). There were significant differences in Lac, SOFA, and NE dosage levels between both groups (p = 0.023, 0.01, 0.023). Survival analysis showed that the 28-day survival rate was significantly higher in the treatment group. CONCLUSION: CRRT using CVVHDF+HP can effectively remove inflammatory factors and improve the prognosis of patients.

Successful treatment of a severe 5-hydroxytrytophan intoxication using carbon hemoperfusion, hemodiafiltration, and mechanical ventilation in a dog.

OBJECTIVE: To describe the successful use of carbon hemoperfusion and hemodiafiltration in combination with mechanical ventilation (MV) to treat a severe intoxication of 5-hydroxytryptophan (5-HTP) in a dog. CASE SUMMARY: A dog ingested a minimum of 550 mg/kg of extended-release 5-HTP, resulting in serotonin syndrome that progressed to a comatose state and severe hypoventilation requiring MV. Extracorporeal carbon hemoperfusion coupled with hemodiafiltration was performed to remove 5-HTP from this patient. A carbon hemoperfusion cartridge was placed in series upstream in the extracorporeal circuit from the hemodialyzer. A total of 46.5 L of blood (4.89 L/kg) was processed during a 4.85-hour treatment. Serial plasma samples were obtained at 0, 60, 90, and 150 minutes during the session and 14 hours after the session. These samples were later analyzed for 5-HTP and serotonin concentrations. The extraction ratio of 5-HTP was 93.6%-98.9% through the carbon filter. The dog was weaned from MV within 8 hours after extracorporeal therapy and, after a full recovery, was successfully discharged. NEW OR UNIQUE INFORMATION PROVIDED: Despite an extensive review of the available literature, this appears to be the first reported case of using a carbon hemoperfusion, hemodiafiltration, and MV to treat severe serotonin syndrome secondary to 5-HTP intoxication in a dog. The combination of carbon hemoperfusion and hemodiafiltration can significantly reduce plasma 5-HTP concentrations after acute intoxication and may serve to decrease morbidity and mortality in patients with severe intoxication.

Effect of Mechanical Vibration on Kinetics of Solute Adsorption.

INTRODUCTION: Hemadsorption with new sorbent cartridges is an emerging extracorporeal blood purification technique. Flow distribution inside the sorbent is one of the main issues concerning the device's performance and optimal sorbent utilization. In this experiment, we aimed to investigate the efficacy of vibration during adsorption by measuring the removal of vancomycin. METHODS: In this experimental study, 1,000 mL of saline with 10 g of vancomycin was circulated in a closed circuit (set flow of 250 mL/min) simulating a hemadsorption blood run using HA380 minimodule cartridge containing 75 g of wet resin. This vibration model was implemented with a damping head device installed in front of the adsorption cartridge during the experiment. The kinetics of the vancomycin were assessed by removal ratio over 120 min. RESULTS: We found no difference between the two models. Adsorption with and without vibration did not differ significantly for partial reduction ratios, overall amount of adsorbed molecule, or adsorption kinetics. CONCLUSION: The current design and structure of the minimodule cartridge demonstrated no difference in small-middle solute removal. Further improvement with the addition of mechanical vibration to the device was not observed.

Application of Hemoperfusion in the Treatment of Acute Poisoning.

Rescue of acute poisoning is a race against time, and it is particularly important to remove toxic substances in time. Traditional methods include gastric lavage, promoting elimination, chelating agents, and other treatments. Hemoperfusion is a common blood purification technique. In the clinical practice of acute poisoning, hemoperfusion can directly remove toxic substances through its unique adsorption effect, showing its excellent efficacy. This paper reviews the experience of hemoperfusion in the treatment of various drug overdoses, pesticides, biological toxins, and industrial poisons, even drug addiction. It is hoped to provide a reference for clinicians in acute poisoning rescue.

The potential role of extracorporeal cytokine removal with CytoSorb® as an adjuvant therapy in Acute Respiratory Distress Syndrome.

Management of acute respiratory distress syndrome (ARDS) represents one of the greatest challenges in intensive care and despite all efforts mortality remains high. One common phenotype of ARDS is that of a secondary injury to a dysregulated inflammatory host response resulting in increased capillary congestion, interstitial lung edema, atelectasis, pulmonary embolism, muscle wasting, recurring infectious episodes, and multiple organ failure. In cases of hyperinflammation, immunomodulation by extracorporeal cytokine removal such as the CytoSorb hemoadsorption cartridge could conceptually enhance lung recovery during the early course of the disease. The aim of this narrative review is to summarize the currently available data in this field and to provide an overview of pathophysiology and rationale for the use of CytoSorb hemoadsorption in patients with hyperinflammatory ARDS.

Novel hemoperfusion adsorbents based on collagen for efficient bilirubin removal - A thought from yellow skin of patients with hyperbilirubinemia.

Hemoperfusion is a well-developed method for removing bilirubin from patients with hyperbilirubinemia. The performance of adsorbents is crucial during the process. However, most adsorbents used for bilirubin removal are not suitable for clinical applications, because they either have poor adsorption performance or limited biocompatibility. Patients with hyperbilirubinemia usually have distinctive yellow skin, indicating that collagen, a primary component of the skin, may be an effective material for absorbing bilirubin from the blood. Based on this idea, we designed and synthesized collagen (Col) and collagen-polyethyleneimine (Col-PEI) microspheres and employed them as hemoperfusion adsorbents for bilirubin removal. The microspheres have an efficient adsorption rate, higher bilirubin adsorption capacity, and competitive adsorption of bilirubin in the bilirubin/bovine serum albumin (BSA) solution. The maximum adsorption capacities of Col and Col-PEI microspheres for bilirubin are 150.2 mg/g and 258.4 mg/g, respectively, which are higher than those of most traditional polymer microspheres. Additionally, the microspheres exhibit excellent blood compatibility originating from collagen. Our study provides a new collagen-based strategy for the hemoperfusion treatment of hyperbilirubinemia.

Nanobody-functionalized conduit with built-in static mixer for specific elimination of cytokines in hemoperfusion.

Removing excessively produced cytokines is of paramount significance in blood purification therapy for hypercytokinemia-associated diseases. In this study, we devised a conduit that is modified with nanobodies (Nb) and incorporates static mixers (Nb-SMC) to eliminate surplus cytokines from the bloodstream. The low-pressure-drop (LPD) static mixer, with each unit featuring two 90°-crossed blades, was strategically arranged in a tessellated pattern on the inner wall of the conduit to induce turbulent mixing effects during the flow of blood. This arrangement enhances mass transfer and molecular diffusion, thereby assisting in the identification and elimination of cytokines. By utilizing computational fluid dynamics (CFD) studies, the Nb-SMC was rationally designed and prepared, ensuring an optimal interval between two mixer units (H/G = 2.5). The resulting Nb-SMC exhibited a remarkable selective clearance of IL-17A, reaching up to 85 %. Additionally, the process of Nb immobilization could be adjusted to achieve the simultaneous removal of multiple cytokines from the bloodstream. Notably, our Nb-SMC displayed good blood compatibility without potential adverse effects on the composition of human blood. As the sole documented static mixer-integrated conduit capable of selectively eliminating cytokines at their physiological concentrations, it holds promise in the clinical potential for hypercytokinemia in high-risk patients. STATEMENT OF SIGNIFICANCE: High-efficient cytokines removal in critical care still remains a challenge. The conduit technique we proposed here is a brand-new strategy for cytokines removal in blood purification therapy. On the one hand, nanobody endows the conduit with specific recognition of cytokine, on the other hand, the build-in static mixer enhances the diffusion of antigenic cytokine to the ligand. The combination of these two has jointly achieved the efficient and specific removal of cytokine. This innovative material is the only reported artificial biomaterial capable of selectively eliminating multiple cytokines under conditions close to clinical practice. It has the potential to improve outcomes for patients with hypercytokinemia and reduce the risk of adverse events associated with current treatment modalities.

A novel recyclable hemoperfusion adsorbent based on TiO2 nanotube arrays for the selective removal of ß2-microglobulin.

Prolonged and excessive accumulation of ß2-microglobulin (ß2m) in the blood can lead to various kidney-related and other diseases. Currently, the most effective method of removing ß2m from the blood is hemoperfusion. Although some traditional hemoperfusion adsorbents such as cellulose and polystyrene microspheres have been used for the removal of ß2m, their selectivity still needs improvement. Immunosorbents have been developed to address this issue, but high cost and limited application are concerns. TiO2 nanotube arrays (TNTAs) have shown great potential in adsorption-related biomedical applications. In this study, we designed and developed a novel TNTA-based hemoperfusion adsorbent for the removal of ß2m, which has demonstrated good biocompatibility, selectivity, and reusability. We investigated the ß2m adsorption capacities of TNTAs with different pore sizes. The results indicate that TNTAs with a pore size matching the size of ß2m exhibit higher adsorption capacity while also having lower adsorption capacity for albumin, showing the importance of pore size on the selectivity of adsorbents. Additionally, green regeneration of TNTAs is achieved via the photocatalytic activity originating from TiO2. Even after five cycles, the adsorption capacity of TNTAs remained above 70%. Our work demonstrates that inorganic materials with ordered pores are capable to be candidates for hemoperfusion, possessing advantages over traditional organic materials such as high stability, security, and low cost.

Adjunctive hemoperfusion with Resin Hemoadsorption (HA) 330 cartridges improves outcomes in patients sustaining multiple Blunt Trauma: a prospective, quasi-experimental study.

BACKGROUND: Multi-organ dysfunction syndrome and multi-organ failure are the leading causes of late death in patients sustaining severe blunt trauma. So far, there is no established protocol to mitigate these sequelae. This study assessed the effect of hemoperfusion using resin-hemoadsorption 330 (HA330) cartridges on mortality and complications such as acute respiratory distress syndrome (ARDS) and systemic inflammatory response syndrome (SIRS) among such patients. METHODS: This quasi-experimental study recruited patients ≥ 15 years of age with blunt trauma, injury severity score (ISS) ≥ 15, or initial clinical presentation consistent with SIRS. They were divided into two groups: the Control group received only conventional acute care, while the case group received adjunctive hemoperfusion. P-values less than 0.05 were statistically significant. RESULTS: Twenty-five patients were included (Control and Case groups: 13 and 12 patients). The presenting vital signs, demographic and injury-related features (except for thoracic injury severity) were similar (p > 0.05). The Case group experienced significantly more severe thoracic injuries than the Control group (Thoracic AIS, median [IQR]: 3 [2-4] vs. 2 [0-2], p = 0.01). Eleven and twelve patients in the Case group had ARDS and SIRS before the hemoperfusion, respectively, and these complications were decreased considerably after hemoperfusion. Meanwhile, the frequency of ARDS and SIRS did not decrease in the Control group. Hemoperfusion significantly reduced the mortality rate in the Case group compared to the Control group (three vs. nine patients, p = 0.027). CONCLUSIONS: Adjunctive Hemoperfusion using an HA330 cartridge decreases morbidity and improves outcomes in patients suffering from severe blunt trauma.

Hemoperfusion with CytoSorb®: Current Knowledge on Patient Selection, Timing, and Dosing.

Direct hemoperfusion with the CytoSorb® adsorbent has experienced widespread use in several critical care settings including sepsis and multiorgan failure. The reported conditions of clinical usage and resulting outcomes vary considerably. The aim of the study was to provide an overview on current treatment recommendations based on the available clinical evidence. We performed a literature analysis using PubMed/MEDLINE and ClinicalTrials.gov to identify clinical data describing parameters of clinical usage of CytoSorb® in patients with septic shock (inclusion and exclusion criteria, starting, and dosing of treatment) and their impact on outcome. The literature search terms yielded 146 entries in September 2022, including clinical case reports, case series, and controlled and uncontrolled clinical trials. Five recommendations were identified linking usage parameters with improved outcome. These were (a) early start of treatment within 12-24 h after onset of septic shock, (b) individualized patient selection (preferably with higher severity scores, procalcitonin >3 ng/mL, serum interleukin 6 >500 pg/mL), (c) exclusion of patients with lactate ≥6 mmol/L or platelets <100 GPT/L, (d) intense treatment (>6 L of blood/kg body weight), and (e) early change of the adsorbent (e.g., every 12 h). Moreover, there is a rationale suggesting therapeutic drug monitoring when possible, avoidance of drug application at the beginning of treatment, and/or usage of increased dosages of antibiotics. However, for the later recommendations, no links to clinical outcome were reported yet. All recommendations are based on the best available knowledge. They need confirmation in future clinical investigations. Currently available clinical data on the use of CytoSorb® in septic patients suggest that early and intense treatment in carefully chosen patients increases the chance of survival. The analysis can inform current clinical practice and future clinical trials.

Hemoperfusion and Immunomodulation.

Recent development in sorbent technology has spurred new interest in the potential of hemoperfusion (HP) in clinical conditions such as cytokine release syndromes and sepsis. Although the role of nonselective HP in such conditions requires solid evidence and more studies, the rationale for clinical application is clearly emerging. Greater biocompatibility and safety of the new sorbents may allow easy and safe application of HP in those conditions where the innate and the adaptive immune response of the individual appears to be dysregulated. Recent results in small studies seem to confirm the plausibility for this therapeutic approach. The concept suggested by the peak concentration hypothesis justifies new studies and the application of HP in selected patients to remove the peaks of circulating mediators responsible for conditions of hyperinflammation or immunodepression.

Chemical-Physical Mechanisms of Adsorption for Blood Purification.

The removal of soluble toxins from blood is necessary in patients with severe kidney failure. The majority of blood purification techniques are based on the use of semipermeable membranes, such as for dialysis treatment. But, whenever there is the need to remove small soluble molecules from blood, the use of such purification techniques may exhibit limited efficiency. This leads to a search for better-performing treatments. Hemoperfusion, given the recent strong advances in the sorption media biocompatibility with plasma (or blood), is considered a promising blood purification technique. This introductive chapter aims at briefly presenting the phenomenology of the adsorption process, also providing some basic elements related to how to use equilibrium load data to define an adsorption isotherm, which can be used to size a hemoperfusion cartridge.

Extracorporeal therapy in the treatment of sepsis: In vitro assessment of the effect of an absorbent cartridge on the circulating bacterial concentration and its interaction with the antibiotic therapy.

Sepsis is one of the major causes of death worldwide. In its physiopathological process, a broad spectrum of pro and antiinflammatory mediators plays a strategic role, leading to a sepsis induced state of immunoparalysis. The rationale behind the employment of extracorporeal purification techniques as a complement to therapy for sepsis is based on their ability to remove the mediators involved. Until now, attention was focused on the immunomodulation allowed by purification therapies. However, the focus of studies on the application possibilities that these techniques offer as a supplement to antimicrobial therapy and resuscitation of critically ill patients must be extended. In this study, the possible removal by adsorption that the Jafron® HA330 cartridge operates against bacteria (S. aureus) was evaluated in vitro. Subsequently, it was evaluated whether the adsorptive capabilities toward bacteria were maintained by using a cartridge functionalized with Vancomycin and whether the latter maintains its bactericidal activity. This study showed that HA330 reduces the circulating bacterial load, even in the presence of pre-adsorbed Vancomycin. Vancomycin, once adsorbed by the cartridge, does not guarantee its bactericidal activity during the 2-h of hemoperfusion treatment.

Hemoperfusion techniques using Jafron HA330 cartridge combined with BBraun Dialog+ dialysis machine in patient with coronavirus disease 2019 pneumonia and septic shock: a case report.

BACKGROUND: The use of hemoperfusion for cytokine removal and inflammatory mediators is increasingly intense, especially in coronavirus disease 2019 patients who are already known to the general public for having cytokine storms. However, we have known about these cytokine storms for a long time in the critical care world. One of the modalities to remove cytokines is to use filtration and adsorption techniques with continuous renal replacement therapy. The use of continuous renal replacement therapy is usually constrained by its very high cost compared with standard care, especially in Indonesia, where health costs are covered by national health insurance. In this case, we use hemodialysis and hemoperfusion, using a dialysis machine, which is more cost-effective and easy to use. CASE PRESENTATION: We used the Jafron HA330 cartridge, modified for the BBraun Dialog+ dialysis machine. This case report presents an 84-year-old Asian man with septic shock due to pneumonia, congestive heart failure, and acute chronic kidney disease accompanied by fluid overload. After undergoing hemodialysis and hemoperfusion separately, there was a gradual and significant clinical improvement. Clinical indicators, including the vasopressor inotropic score and infection markers, should all be considered when deciding whether to begin hemodialysis and hemoperfusion. CONCLUSION: In general, using hemoperfusion to treat septic shock patients can reduce the length of stay in the intensive care unit, and morbidity and mortality.
