Abstract

Introduction: Enkephalins, endogenous opioid peptides, are involved in the regulation of renal function. One derived molecule, proenkephalin A, also known as penKid, has been demonstrated to be a reliable biomarker for kidney function and its plasma concentration correlates with measured glomerular filtration rate. penKid is used for prediction and diagnosis of AKI and need of renal replacement therapy (RRT). penKid has also been used to predict the successful weaning from RRT in patients with AKI. Whether the concentration of penKid is affected or not by RRT is a controversial point and there are no studies describing the kinetics of the molecule in such conditions. The low molecular weight (4.5 kDa) would imply free removal by the glomerulus and the dialysis membranes. During RRT, this reduction could not be detected in clinical practice due to the complex kinetics involving either low dialytic clearance or increased production in response to impaired kidney function. The aim of this study was to determine the sieving coefficient and the diffusive clearance of the penKid molecule in conditions of in vitro continuous veno-venous hemofiltration (CVVH) and continuous veno-venous hemodialysis (CVVHD), respectively, and also the penKid removal ratio in conditions of in vitro hemoadsorption (HA) using a synthetic microporous resin. Methods: Blood spiked with a lyophilized penKid peptide solved in 20 mm dipotassium phosphate and 6 mm disodium EDTA [pH 8] to reach target concentrations is used as testing solution. In each experiment, the blood batch was adjusted at a volume of 1,000 mL, maintained at 37°, and continuously stirred. Samples were collected from blood, ultrafiltrate, and spent dialysate at different times during the experiments. Sieving, clearance, and removal ratio were calculated. Results: Significant removal of penKid was observed in CVVH (sieving 1.04 ± 0.27), in CVVHD (clearance 23.08 ± 0.89), and in HA (removal ratio 76.1 ± 1% after 120 min). Conclusion: penKid is effectively removed by extracorporeal therapies. In presence of anuria, penKid generation kinetics can be calculated based on extracorporeal removal and volume variation. In steady state conditions, declining values may be the result of an initial renal function recovery and may suggest discontinuation and successful liberation from RRT. [ABSTRACT FROM AUTHOR]

Abstract

Introduction: Per- and polyfluoroalkyl substances (PFAS) are known water pollutants leading to potential public health consequences. High blood levels of PFAS have been associated with several pathological conditions including testicular and kidney cancer. Classic extracorporeal therapies have demonstrated limited efficiency, and new approaches should be explored. In this study, we studied the possible role of hemoadsorption to achieve a fast, safe, and effective removal of PFAS from blood in patients with high blood levels. Methods: We developed an in vitro model of hemoadsorption to test the potential of PFAS removal by extracorporeal treatment. We recirculated a highly polluted batch of water (4 L) through a sorbent cartridge (Jafron Medical, Zhuhai, China) for 120 min at a flow of 150 mL/min. We collected samples at different time points and analyzed 39 different PFAS compounds. Results: For the PFAS compounds with concentrations significantly above normal, we observed a removal ratio close to 90% already within the first 60 min of circulation leading to almost complete elimination of all pollutants at 120 min. Conclusions: The in vitro model of hemoadsorption suggests the possible application in vivo of this technique to reduce/normalize the concentrations of PFAS in patients exposed to water or environmental pollution.

Abstract

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. [ABSTRACT FROM AUTHOR]

Abstract

Background: The level of bacteremia in patients with sepsis and septic shock is a predictor of complications and mortality, regardless of the type of bacteria. Devices for bacteria, endotoxin and cytokines removal by adsorption have been recently developed. Thus, extracorporeal blood purification therapies have been proposed as adjunctive therapy in sepsis in combination with drugs. Some potentially useful drugs, however, are precluded due to their organ or metabolic toxicity. The present study represents a preliminary report on the in vitro effect of a sorbent device (minimodule with HA380 beads, Jafron medical, Zhuhai, China) in which the particles have been functionalized with vancomycin on the surface. The impact of the surface‐modified beads on circulating bacteria (Staphylococcus aureus) has been tested in a simulated in vitro circulation. Methods: In vitro experiments were carried out with 800 mL of blood enriched with S. aureus species. Blood was circulated in the vancomycin‐functionalized and non‐functionalized mini‐module cartridges in hemoadsorption setup (300 mL each) and the bactericidal effect was assessed. Also, 200 mL of blood was used as a control. Results: A significant increase in the time to positivity of blood cultures was observed after 60 min and also after 120 min of therapy with the mini‐module functionalized with vancomycin as opposed to the non‐functionalized cartridge. Conclusions: These results suggest a possible way of treating sepsis by using drug‐ or antibiotic‐functionalized cartridges without worrying about pharmacological toxicity. The prolongation of the time to bacterial culture positivity to S. aureus after a passage through a column packed with beads functionalized with vancomycin represents a proof of concept.

Abstract

Introduction: The present study aimed to monitor peritoneal neutrophil gelatinase-associated lipocalin (pNGAL) during peritonitis episodes and to enhance its diagnostic value by evaluating pNGAL at scheduled times in parallel with white blood cell (WBC) count. In addition, we investigated possible correlations between pNGAL and the etiology of peritonitis, evaluating it as a possible marker of the clinical outcome. Methods: Twenty-two patients with peritoneal dialysis (PD)-related peritonitis were enrolled. Peritonitis was divided into Gram-positive, Gram-negative, polymicrobial, and sterile. WBC count and neutrophil gelatinase-associated lipocalin (NGAL) in PD effluent were measured at different times (days 0, 1, 5, 10, 15, and/or 20 and 10 days after antibiotic therapy discontinuation). NGAL was measured by standard quantitative laboratory-based immunoassay and by colorimetric NGAL dipstick (NGALds) (dipstick test). Results: We found strong correlations between peritoneal WBC, laboratory-based NGAL, and NGALds values, both overall and separated at each time point. On day 1, we observed no significant difference in WBC, both NGALds (p = 0.3, 0.9, and 0.2) between Gram-positive, Gram-negative, polymicrobial, and sterile peritonitis. No significant difference has been found between de novo versus relapsing peritonitis for all markers (p > 0.05). We observed a parallel decrease of WBC and both NGAL in patients with favorable outcomes. WBC count and both pNGAL resulted higher in patients with negative outcomes (defined as relapsing peritonitis, peritonitis-associated catheter removal, peritonitis-associated hemodialysis transfer, peritonitis-associated death) at day 10 (p = 0.04, p = 0.03, and p = 0.05, respectively) and day 15 (p = 0.01, p = 0.04, and tendency for p = 0.005). There was a tendency toward higher levels of WBC and NGAL in patients with a negative outcome at day 5. No significant difference in all parameters was proven at day 1 (p = 0.3, p = 0.9, p = 0.2) between groups. Conclusion: This study confirms pNGAL as a valid and reliable biomarker for the diagnosis of PD-peritonitis and its monitoring. Its trend is parallel to WBC count during peritonitis episodes, in particular, patients with unfavorable outcomes. [ABSTRACT FROM AUTHOR]

Abstract

Background: Extracorporeal removal of bilirubin in patients with severe liver dysfunction is a key blood purification strategy. We conducted an ex vivo study to assess the quantitative capacity to remove bilirubin from plasma of a novel adsorptive cartridge. Methods: We studied a downscaled module of the BS330 Plasma Bilirubin Adsorption Column Cartridge (Jafron Biomedical, Zhuhai City, China) to minimize the plasma requirement in an ex vivo circulation using a solution of hyperbilirubinemic plasma. We measured the bilirubin concentration gap (ΔC) between inlet (Cpin) and outlet (Cpout) of the unit and we calculated the removal ratio (RR) as mass adsorbed at different time points. Moreover, we compared the ex vivo model with the bilirubin adsorption kinetics in a patient with acute on chronic liver failure treated with the BS330 cartridge. Results: Bilirubin concentration change across the cartridge at 30 min was 16.5%, and cartridge saturation was reached at 750 min. We used a minimodule downscaled to 1:3 and containing approximately 131 g of BS330 sorbent beads: the device retained 759 mg of bilirubin with a RR of 78.1% and a RR of 42.6% at 120 min. Thus, the adsorption capacity was 5.76 mg of bilirubin per gram of sorbent. Bilirubin adsorption kinetics in our clinical case with a full-scale unit shows a coherent trend with a total bilirubin mass adsorbed after 180 min of 470 mg. Discussion: Our findings provide the first assessment of bilirubin adsorption in an ex vivo model of plasma perfusion and can be used to design interventional studies in humans, providing guidance for an adequate prescription of treatment frequency and duration.
