AbstractThe objective of this single-center retrospective cohort study was to investigate the relationship between blood transfusion and persistent inflammation, immunosuppression, and catabolism syndrome (PIICS). The study was conducted at the Critical Care Center at Toho University Omori Medical Center, Japan. We included 391 patients in the PIICS group (hospitalization for > 15 days, C-reactive protein > 3.0 mg/dL or albumin < 3.0 mg/dL or lymph < 800/μL on day 14) and 762 patients in the non-PIICS group (hospitalization for > 15 days and not meeting the PIICS criteria). We performed univariate and multivariate logistic regression analyses using PIICS as the objective variable and red blood cell (RBC) or fresh frozen plasma or platelet (PLT) transfusion and other confounding factors as explanatory variables. In addition, we conducted a sensitivity analysis using propensity score matching analysis. The multivariate and propensity score analyses showed that RBC and PLT transfusions were significantly associated with PIICS. This is the first study to report an association between RBC and PLT transfusions and PIICS. Our findings have contributed to better understanding the risk factors of PIICS and suggest that physicians should consider the risk of PIICS occurrence when administering blood transfusions in intensive care unit (ICU) patients.

AbstractConvalescent plasma is used to treat COVID-19. There are theoretical concerns about the impact of pro-coagulant factors in convalescent plasma on the coagulation cascade particularly among patients with severe COVID-19. The aim of this study was to evaluate the coagulation profile of COVID-19 convalescent plasma. Clotting times and coagulation factor assays were compared between fresh frozen plasma, COVID-19 convalescent plasma, and pathogen-reduced COVID-19 convalescent plasma. Measurements included prothrombin time, activated partial thromboplastin time, thrombin time, fibrinogen, D-dimer, von Willebrand factor activity, von Willebrand factor antigen, coagulation factors II, V, VII–XII, protein S activity, protein C antigen, and alpha-2 plasmin inhibitor. Clotting times and coagulation factor assays were not different between COVID-19 convalescent plasma and fresh frozen plasma, except for protein C antigen. When compared to fresh frozen plasma and regular convalescent plasma, pathogen reduction treatment increased activated partial thromboplastin time and thrombin time, while reducing fibrinogen, coagulation factor II, V, VIII, IX, X, XI, XII, protein S activity, and alpha-2 plasmin inhibitor. The coagulation profiles of human COVID-19 convalescent plasma and standard fresh frozen plasma are not different. Pathogen reduced COVID-19 convalescent plasma is associated with reduction of coagulation factors and a slight prolongation of coagulation times, as anticipated. A key limitation of the study is that the COVID-19 disease course of the convalesced donors was not characterized.

Introduction.  This study aimed to determine if thromboelastography (TEG) is associated with reduced blood product use and surgical re-intervention following cardiopulmonary bypass (CPB) compared to traditional coagulation tests. Methods.  A retrospective review was conducted of 698 patients who underwent CPB  at a tertiary-care, community-based, university-affiliated hospital from February 16, 2014 – February 16, 2015 (Period I) and May 16, 2015 - May 16, 2016 (Period II).  Traditional coagulation tests guided transfusion during Period I and TEG guided transfusion during Period II.  Intraoperative and postoperative administration blood products (red blood cells, fresh frozen plasma, platelets, and cryoprecipitate), reoperation for hemorrhage or graft occlusion, duration of mechanical ventilation, hospital length of stay and mortality were recorded.  Results.  Use of a TEG-directed algorithm was associated with a 13.5% absolute reduction in percentage of patients requiring blood products intraoperatively (48.2% vs. 34.7%, p <0.001).  TEG resulted in a 64.3% and 43.1% reduction in proportion of patients receiving FFP and platelets, respectively, with a 50% reduction in volume of FFP administered (0.3 vs. 0.6 units, p < 0.001).  Use of TEG was not observed to significantly decrease postoperative blood product usage or mortality.  The median length of hospital stay was reduced by 1 day after TEG guided transfusion was implemented (nine days vs. eight days, p = 0.01). Conclusions.  Use of TEG-directed transfusion of blood products following CPB appears to decrease the need for intraoperative transfusions, but the effect on clinical outcomes has yet to be clearly determined.

Background and aim of the study To evaluate whether the release and perfuse technique implies a circulatory arrest time comparable with or shorter than those of standard Frozen Elephant Trunk technique in aortic arch surgery. Methods We retrospectively reviewed the records of patients who had undergone aortic arch repair with Release and Perfuse Technique (RPT) or standard Frozen Elephant Trunk (FET) at our Institution between January 2018 and May 2021. Primary endpoints were the comparison of circulatory arrest time, perioperative variables, and complications between two groups. A propensity score weighting approach was used for data analysis. Results A total of 41 patients underwent aortic arch surgery were analyzed:15 (37%) and 26 (63 %) in RPT and FET group, respectively. The use of RPT showed a significant shorter circulatory arrest times than FET: 9 min vs 58 min (P < 0.001), respectively. The median lactates peak in the first 24h post intervention was 2.6 for RPT group and 5.4 mmol/L for FET group, (P <0.0001). When compared with the FET, RPT is associated with significant reduction in the use of packed red blood cells (P <0.0001), fresh frozen plasma (P <0.0001), platelet concentrate (P <0.0001), and fibrinogen (P <0.004). The median ICU stay was 3 and 9 days (P = 0.011), whereas the median hospital stay was 12 and 18.5 days (P=0.004) in the RPT and FET groups, respectively. Thirty-day mortality and postoperative outcomes were comparable between the two groups. Conclusions Considering the anatomical limitations related to the use of this technique, the RPT appears to be safe, feasible, and effective in reducing the circulatory arrest time during aortic arch surgery. Nevertheless, further studies are required to demonstrate its safety and efficacy.

Background: Hereditary angioedema (HAE) is an autosomal dominant disorder. The characteristic of HAE is recurrent angioedema episodes due to low C1 esterase inhibitor (C1-INH) level. HAE symptoms, especially those affecting oropharynx or larynx may develop respiratory distress syndrome due to impaired airway, which can be potentially fatal. Case: We report a clinical case of a 57 year-old woman, with type I HAE, scheduled for total laparoscopic hysterectomy under general endotracheal anesthesia, which was done successfully without inducing airway edema. Danazol, which increases liver synthesis of C1-INH, was administered and fresh frozen plasma (FFP), which contained C1-INH, was transfused after induction.Conclusions: For HAE patients, the greatest concern is that general anesthesia can induces upper airway edema by direct mucosal irritation by the endotracheal tube. The perioperative management should include both prophylactic increase of C1-INH production and on-demand administration of C1-INH or FFP.

Purpose The primary aim of this study was to examine the effects of two oxygenator systems on major adverse events and mortality. Methods A total of 181 consecutive patients undergoing coronary artery bypass grafting in our clinic were retrospectively analyzed. The patients were divided into two groups according to the oxygenator used: Group M, in which a Medtronic Affinity (Medtronic Operational Headquarters, Minneapolis, MN, USA) oxygenator was used, and Group S, in which a Sorin Inspire (Sorin Group Italia, Mirandola, Italy) oxygenator was used. Results Group S consisted of 89 patients, whereas Group M included 92 patients. No statistically significant differences were found between the two groups in terms of age ( p = .112), weight ( p = .465), body surface area ( p = .956), or gender ( p = .484). There was no statistically significant difference in hemorrhage on the first or second postoperative day ( p = .318 and p = .455, respectively). No statistically significant differences were observed in terms of red blood cell ( p = .468), fresh frozen plasma ( p = .116), or platelet concentrate transfusion ( p = .212). Infections, wound complications, and delayed sternal closure were significantly more common in Group M ( p = .006, p = .023, and p = .019, respectively). Extracorporeal membrane oxygenators and intra-aortic balloon pumps were required significantly more frequently in Group S ( p = .025 and p = .013, respectively). Major adverse events occurred in 16 (18%) patients in Group S and 14 (15.2%) patients in Group M ( p = .382). Mortality was observed in six (6.7%) patients in Group S and three (3.3%) patients in Group M ( p = .232). No statistically significant difference was found between the two groups in terms of length of hospital stay ( p = .451). Conclusion The clinical outcomes of the two oxygenator systems, including mortality, major adverse events, hemorrhage, erythrocyte and platelet transfusions, and length of hospital stay, were similar.

Background: Hereditary C1q deficiency is associated with early-onset autoimmunity causing SLE or SLE-like disease as well as increased risk for infections with encapsulated bacteria. It is a rare genetic condition inherited in an autosomal recessive manner, caused by mutations in C1q genes. Treatment and management of this rare disease are very complex and include prophylactic vaccination, antibiotics, and immunosuppressive drugs. There are two possible modalities for the replacement of the missing protein: regular fresh frozen plasma (FFP) administration and allogeneic hematopoietic stem cell transplant because the protein is derived from monocytes. Replacing C1q with FFP is being attempted in some patients with success in controlling the disease and in avoiding flare.Case Report: We report a case of sixteen-month-old girl with ulcerations in her mouth, skin erythema, and elevated liver enzymes. ANAs were positive, antibodies against dsDNA were negative, but she had positive anti-Smith antibodies. Complement complements C3 and C4 levels were normal. Total complement activity, classical pathway (hemolytic test) was deficient and C1q antigen was below the detection limit supporting the presence of C1q deficiency. The girl has pathogenic homozygous nonsense mutation in C1qC gene, Arg69Ter (c205&gt;T). The initial response to corticosteroid therapy was good. Regular fresh frozen plasma infusions keep her disease under control, and we were able to reduce the dose of corticosteroids.Conclusion: Young patients with cutaneous lesions resembling SLE, early onset of autoimmunity, with normal C3, C4, elevated ANAs, and negative anti-dsDNA, C1q deficiency should be suspected and complement screening tests should be done. It is important to exclude secondary C1q deficiency. FFP in our patient seems to be well tolerated, without any side effects, able to control the disease.

Background:Transfusion of blood and blood products if employed safely, with intensive care can save manyvaluable lives. But a number of transfusion reactions may develop that are sometimesmore serious and life threatening.So this study was done to find out the most frequent and life threatening reactions that develop during transfusion. Methods: A Cross sectional descriptive observational study was performed at a tertiary care centre. Patients of 18 years and older irrespective of sexes who received blood and blood products due to different reasons between April 2020 to September 2020 were included in this study. A total of 96 patients were included in the study. Results:In thisstudy 11(11.5%) out of 96 patients had transfusion reactions of different types .Febrile non haemolytic reaction was the highest with 8 patients (8.33%),followed by Allergic reaction in 2 patients(2.08%) and Acute haemolytic transfusion reaction in 1 patient (1.04%).Among them 7(63.6%) reactions occurred with whole blood , 2(18.2%) reactions occurred with red cell concentrate and 1 reaction occurred with Apheresis platelet (9.1%) and fresh frozen plasma(9.1%).Statistically significant association was found between duration of storage of blood and transfusion reaction. Conclusion: Febrile non haemolytic reaction was the commonest type of transfusion reaction found in this study and there was also statistically significant association between duration of storage of blood and transfusion reaction.
