Abstract
Normothermic machine perfusion (NMP) enables viability assessment of donor livers prior to transplantation. NMP is frequently performed by using human blood products including red blood cells (RBCs) and fresh frozen plasma (FFP). Our aim was to examine the efficacy of a novel machine perfusion solution based on polymerized bovine hemoglobin-based oxygen carrier (HBOC)-201. Twenty-four livers declined for transplantation were transported by using static cold storage. Upon arrival, livers underwent NMP for 6 hours using pressure-controlled portal and arterial perfusion. A total of 12 livers were perfused using a solution based on RBCs and FFPs (historical cohort), 6 livers with HBOC-201 and FFPs, and another 6 livers with HBOC-201 and gelofusine, a gelatin-based colloid solution. Compared with RBC + FFP perfused livers, livers perfused with HBOC-201 had significantly higher hepatic adenosine triphosphate content, cumulative bile production, and portal and arterial flows. Biliary secretion of bicarbonate, bilirubin, bile salts, and phospholipids was similar in all 3 groups. The alanine aminotransferase concentration in perfusate was lower in the HBOC-201-perfused groups. In conclusion, NMP of human donor livers can be performed effectively using HBOC-201 and gelofusine, eliminating the need for human blood products. Perfusing livers with HBOC-201 is at least similar to perfusion with RBCs and FFP. Some of the biomarkers of liver function and injury even suggest a possible superiority of an HBOC-201-based perfusion solution and opens a perspective for further optimization of machine perfusion techniques.

Analytical interference of HBOC-201 (Hemopure, a synthetic hemoglobin-based oxygen carrier) on four common clinical chemistry platforms. Clin Chim Acta 2018; 482:33-39. [PMID: 29580857 DOI: 10.1016/j.cca.2018.03.017] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2018] [Revised: 03/16/2018] [Accepted: 03/16/2018] [Indexed: 11/20/2022]
Abstract
BACKGROUND There are 13 million blood transfusions each year in the US. Limitations in the donor pool, storage capabilities, mass casualties, access in remote locations and reactivity of donors all limit the availability of transfusable blood products to patients. HBOC-201 (Hemopure®) is a second-generation glutaraldehyde-polymer of bovine hemoglobin, which can serve as an "oxygen bridge" to maintain oxygen carrying capacity while transfusion products are unavailable. Hemopure presents the advantages of extended shelf life, ambient storage, and limited reactive potential, but its extracellular location can also cause significant interference in modern laboratory analyzers similar to severe hemolysis. METHODS Observed error in 26 commonly measured analytes was determined on 4 different analytical platforms in plasma from a patient therapeutically transfused Hemopure as well as donor blood spiked with Hemopure at a level equivalent to the therapeutic loading dose (10% v/v). RESULTS Significant negative error ratios >50% of the total allowable error (>0.5tAE) were reported in 23/104 assays (22.1%), positive bias of >0.5tAE in 26/104 assays (25.0%), and acceptable bias between -0.5tAE and 0.5tAE error ratio was reported in 44/104 (42.3%). Analysis failed in the presence of Hemopure in 11/104 (10.6%). Observed error is further subdivided by platform, wavelength, dilution and reaction method. CONCLUSION Administration of Hemopure (or other hemoglobin-based oxygen carriers) presents a challenge to laboratorians tasked with analyzing patient specimens. We provide laboratorians with a reference to evaluate patient samples, select optimal analytical platforms for specific analytes, and predict possible bias beyond the 4 analytical platforms included in this study.

Abstract
Clinical laboratories frequently encounter samples showing significant haemolysis, icterus or lipaemia. Technical advances, utilizing spectrophotometric measurements on automated chemistry analysers, allow rapid and accurate identification of such samples. However, accurate quantification of haemolysis, icterus and lipaemia interference is of limited value if laboratories do not set rational alert limits, based on sound interference testing experiments. Furthermore, in the context of increasing consolidation of laboratories and the formation of laboratory networks, there is an increasing requirement for harmonization of the handling of haemolysis, icterus and lipaemia-affected samples across different analytical platforms. Harmonization may be best achieved by considering both the analytical aspects of index measurement and the possible variations in the effects of haemolysis, icterus and lipaemia interferences on assays from different manufacturers. Initial verification studies, followed up with ongoing quality control testing, can help a laboratory ensure the accuracy of haemolysis, icterus and lipaemia index results, as well as assist in managing any biases in index results from analysers from different manufacturers. Similarities, and variations, in the effect of haemolysis, icterus and lipaemia interference in assays from different manufacturers can often be predicted from the mechanism of interference. Nevertheless, interference testing is required to confirm expected similarities or to quantify differences. It is important that laboratories are familiar with a number of interference testing protocols and the particular strengths and weaknesses of each. A rigorous approach to all aspects of haemolysis, icterus and lipaemia interference testing allows the analytical progress in index measurement to be translated into improved patient care.

Abstract
OBJECTIVE To evaluate interference by the hemoglobin-based oxygen carrier Hemospan on clinical laboratory assays. DESIGN AND METHODS Interfering Hemospan concentrations were determined for general chemistry and cardiac marker analytes in pooled serum and the corresponding hemolysis index was calculated. RESULTS Hemospan did not interfere with 20 of 35 analytes. Hemospan produced a negative interference in serum creatinine, amylase, alkaline phosphatase, uric acid, and GGT assays and a positive interference in serum phosphate, LDH, iron, triglycerides, total protein, AST, cholesterol, magnesium, and albumin assays, and appeared to positively bias the serum cardiac troponin I (cTnI) assay only when cTnI is present in the sample. CONCLUSIONS We present a report of assays affected by Hemospan and the threshold concentrations for interference. This study highlights the importance of interference studies in understanding the effects of hemoglobin-based oxygen carriers on results reported by the clinical laboratory.

Abstract
We sought to determine whether hemoglobin-based oxygen carriers (HBOCs), hemoglobin glutamer-200 [bovine] (HBOC-200, Oxyglobin), hemoglobin glutamer-250 [bovine] (HBOC-201, Hemopure), and hemoglobin raffimer (Hemolink) interfere with the accuracy of lactate measurements. Combinations of concentrated L-lactate solution, HBOC, and blood or plasma with added PlasmaLyte-A were added to sample tubes to make a linear and constant increase in lactate concentration in consecutive samples. Sample lactate concentrations ranged from 5-110 mg/dL (0.6-12 mm) (physiological reference range: 5-20 mg/dL [0.56-2.2 mm]). Comparisons were made between machine measured lactate concentrations and calculated lactate concentrations. For Hb glutamer-250, the average difference between measured and calculated lactate concentrations was -5.1 mg/dL (-0.57 mm) (LX-20), with greater underestimation at larger lactate concentrations. For Hb raffimer, the average difference was -2.2 mg/dL (-0.24 mm) (LX-20). The veterinary product, Hb glutamer-200, was tested on 3 analyzers (LX-20(R), YSI 1500, and YSI 2300). The YSI 1500 was the most accurate instrument with the mean difference between measured minus calculated lactate being +1.3 mg/dL versus -2.6 mg/dL (YSI 2300) and -8.4 mg/dL (LX-20). The clinical implications of this study are that with increasing levels of an HBOC in plasma, lactate interpretation may become inaccurate, especially at larger lactate concentrations, causing underestimation of measured lactate values and possible under-treatment of the patient. Therefore, caution must be exercised when interpreting lactate results when a HBOC is present in plasma.

Abstract
Hemoglobin vesicles (HbV, diameter: 251 +/- 81 nm) are artificial oxygen (O2) carriers encapsulating concentrated hemoglobin (Hb) solution with phospholipid bilayer membrane, and their O2 transporting ability in vivo has been extensively studied. It is important to clarify the interference of the HbV suspension in clinical laboratory tests performed on serum and to establish a pretreatment method to avoid such an interference. The HbV suspension, acellular Hb solution ([Hb] = 10 g/dl) or saline, was mixed with a pooled human serum at various ratios up to 50 vol% ([Hb] = 5 g/dl), and the magnitude of the interference effect of HbV and Hb on 30 analytes was studied. The mixture of the HbV suspension and serum was ultracentrifuged (50,000 g, 20 min) to remove the HbV particles as precipitate, and the supernatant was analyzed and compared with the saline control group. The HbV particles were also removed by centrifugation (2,700 g, 30 min) in the presence of dextran (Mw 200 kDa). The HbV suspension showed considerable interference effects in most analytes. The majority of these effects was more serious than those of the acellular Hb solution. These findings are thought to be due to the light absorption of Hb in HbV and/or the light scattering generated in the suspension that interferes with the colorimetric and turbidimetric measurements. The components of HbV may also interfere with the chemical reactions of the studied assays. However, removal of the HbV from the supernatant diminished the interference in most of the assays: this is an advantage of HbV in comparison with acellular chemically modified Hb solutions.

Abstract
Concerns about the infectious and immunosuppressive risks of allogeneic blood products persist, and the increased disproportion of blood donation and consumption has reinforced the search for alternative erythrocyte transfusion strategies in recent years. With the absence of problems such as nephro-toxicity, increased colloid osmotic pressure and sudden renal clearance, modern haemoglobin based oxygen carriers (HBOC) have shown their effectiveness and tolerability in numerous animal and several clinical studies. HBOC can be infused without prior cross-matching and are now available as stable formulations with long shelf-life. Most clinical studies have been performed with human cross-linked haemoglobin (DCLHb) but all trials were stopped two years ago because of an increased mortality in two clinical trials in patients who received DCLHb after stroke and multiple injury shock. However, experimental trials in animals are in progress with DCLHb and recombinant human haemoglobin. In contrast, Phase III studies with polymerised bovine haemoglobin (HBOC-201) are finished or currently under evaluation showing that infusion of HBOC-201 can avoid or reduce allogeneic blood transfusion needs in specific peri-operative settings. As a consequence, HBOC-2001 was actually approved for treatment of peri-operative anaemia in elective adult surgical patients in South Africa. Other human or bovine haemoglobin solutions are currently being investigated in different clinical studies in cardiac surgery patients, sepsis and tumour patients. More recent investigations have shown that HBOC are not only simple erythrocyte transfusion substitutes but highly effective oxygen donators in terms of tissue oxygenation. HBOC open the door for a new therapeutic strategy: plasmatic oxygen delivery with physiological concentrations of inspired oxygen. In specific situations (e.g., ischaemia or arterial stenosis) HBOC have advantages over red blood cells because they can reach post-stenotic or poorly perfused tissues with the plasma stream, where erythrocytes are not able to pass. In addition to significant plasmatic oxygen transport, HBOC also enhance tissue oxygenation because of the facilitated oxygen release by HBOC and from remaining erythrocytes. Further studies will show, if the outcome of patients with impaired perfusion (e.g., stroke or myocardial infarction) can be improved by prophylactic or therapeutic application of HBOC. Whenever these formulations are globally launched, they will find differential indications as potent oxygen-delivering drugs in addition to the globally recognised goal of red cell substitutes in cases of bleeding.
