The effects of emicizumab on in vitro coagulation and fibrinolysis parameters in patients with disseminated intravascular coagulation with and without addition of anti-FVIII antibody.

BACKGROUND: Emicizumab (Emi) is used as haemostatic prophylaxis for patients with haemophilia A (PwHA). Disseminated intravascular coagulation (DIC) is a condition characterized by persistent systemic activation of coagulation, but there is yet no information on coagulation and fibrinolysis potentials in Emi-treated PwHA with DIC. AIM: To examine the effect of Emi on coagulation and fibrinolysis potentials in HA-model DIC plasmas. METHODS: Plasma from a patient with sepsis-DIC (seven patients) was treated with anti-factor (F)VIII monoclonal antibody (HA-model DIC plasma) and incubated with Emi (50 µg/mL). The plasma was then assessed using clot-fibrinolysis waveform analysis (CFWA). Coagulation and fibrinolysis parameters were expressed as ratios relative to normal plasma (|min1|-ratio and |FL-min1|-ratio, respectively). PATIENTS AND RESULTS: In case 1, coagulant potential was slightly high and fibrinolytic potential was extremely low, presenting a coagulant-dominant state (|min1|-ratio/|FL-min1|-ratio: 1.1/.38). In cases 2-5, fibrinolytic potential was not suppressed, but there were marked hypercoagulant potentials, indicating relative coagulant-dominant states. In case 6, coagulant and fibrinolytic potentials were increased but well balanced (|min1|-ratio/|FL-min1|-ratio: 1.38/1.28). In case 7, both potentials were severely deteriorated in not only CFWA but also the thrombin/plasmin generation assay. The addition of Emi into the HA-model DIC plasmas increased |min1|-ratio values in all cases, but the coagulant potentials did not exceed the initial ones (DIC plasma before treatment with anti-FVIII antibody). CONCLUSIONS: The presence of Emi in the HA-model DIC plasma improved coagulation potentials, but did not increase coagulation potentials beyond those of DIC plasma in non-HA states.

A systematic review and meta-analysis of recombinant human soluble thrombomodulin for the treatment of DIC associated with hematological malignancies.

BACKGROUND: Recombinant human soluble thrombomodulin (rhTM) is commonly used in Japan to treat disseminated intravascular coagulation (DIC), but its efficacy compared with other anticoagulants is unclear. We conducted a systematic review and meta-analysis to investigate this issue in DIC patients with hematological malignancies. METHODS: We searched PubMed, Cochrane, and Scopus for prospective and retrospective studies evaluating the efficacy and safety of rhTM in DIC patients with hematological malignancies between April 2008 and April 2023. We performed a systematic review and meta-analysis evaluating recovery from DIC, hemorrhagic adverse events (AEs), and overall survival (OS). RESULTS: We analyzed one prospective (64 patients) and seven retrospective studies (209 patients). Use of rhTM was associated with a higher rate of recovery from DIC (OR: 2.25 [1.09-4.63] and 1.98 [1.12-3.50] in prospective and retrospective studies, respectively; same order below) and fewer hemorrhagic AEs (OR: 0.83 [0.30-2.30] and 0.21 [0.08-0.57]). rhTM did not improve OS (OR: 1.06 [0.42-2.66] and 1.72 [0.87-3.39]), although the incidence of hemorrhagic death was lower in the rhTM group (0 of 94 patients). CONCLUSION: Use of rhTM in patients with hematological malignancy-associated DIC is strongly expected to be effective and safe.

Efficacy and safety of heparin for sepsis-induced disseminated intravascular coagulation (HepSIC): study protocol for a multicenter randomized controlled trial.

BACKGROUND: Disseminated intravascular coagulation (DIC) occurs in 30-50% of septic patients and contributes to high mortality in the intensive care unit (ICU). However, there are few proven interventions for coagulation disorder management in sepsis. Experimental and clinical data have demonstrated that sepsis could benefit from unfractionated heparin (UFH) treatment. To date, there are no large multicenter trials to determine the safety and efficacy of UFH in septic patients with suspected DIC. METHODS: A multicenter, double-blinded, placebo-controlled randomized trial is designed to recruit 600 patients who met sepsis 3.0 criteria and suspected DIC. Participants will be randomized (1:1) to receive UFH or saline via continuous intravenous administration for 7 days within 6 h of enrolment. The primary outcome is ICU mortality. The secondary outcome includes 28-day all-cause mortality, the improvement of Sequential Organ Failure Assessment scores, and the incidence of major hemorrhage. Investigators, participants, and statisticians will be blinded to the allocation. DISCUSSION: The HepSIC trial is to evaluate the efficacy and safety of UFH on sepsis-related DIC across different areas of China. The small dosage of UFH administration would offer a new potential approach for treating sepsis-related coagulation disorders. ETHICS AND DISSEMINATION: Ethical approval was granted by all the ethics committees of 20 participant centers. Results will be disseminated via peer-reviewed publications and presented at conferences. TRIAL REGISTRATION: ClinicalTrials.gov NCT02654561. Registered on 13 January 2016.

The two therapeutic strategies of surgical intervention and medical management in a patient with enhanced-fibrinolytic type of disseminated intravascular coagulation after aortic replacement for Stanford type A aortic dissection with chronic heart and renal failure.

BACKGROUND: Management of the enhanced-fibrinolytic type of disseminated intravascular coagulation (DIC) caused by aortic disorders is the two strategies of surgical intervention and medical treatment based on the patient's age and comorbidities. CASE PRESENTATION: An 81-year-old woman with a history of two previous aortic surgeries and chronic heart and renal failure was admitted for uncontrollable subcutaneous hemorrhage. The hemorrhage was caused by the enhanced-fibrinolytic type of disseminated intravascular coagulation (DIC) caused by periprosthetic graft hematoma after aortic replacement for Stanford type A aortic dissection. Open thoracic hemostasis temporarily controlled the subcutaneous hemorrhage, but she was readmitted for the recurrence seven months after discharge. On the second admission, the combination of anticoagulant and antifibrinolytic agents was successful. CONCLUSION: Management of the enhanced-fibrinolytic type of DIC caused by aortic disorders is important of a successful combination of surgical and medical therapy tailored the patient's condition.

Prolonged venom-induced consumptive coagulopathy following Mangshan pit viper (Protobothrops mangshanensis) envenomation despite Hemato Polyvalent antivenom administration.

This case report summarizes an envenomation by the Mangshan pit viper (Protobothrops mangshanensis), a rare, endangered, venomous snake endemic to Mount Mang of China, and the first reported use of Hemato Polyvalent antivenom (HPAV) for this species. The snakebite occurred in a United States zoo to a 46-year-old male zookeeper. He presented via emergency medical services to a tertiary center after sustaining a single P. mangshanensis bite to the abdomen and was transported with antivenom from the zoo. Within 2 hours of envenomation, he developed oozing of sanguineous fluid and ecchymosis at the puncture site, and about 4 hours post-bite, was treated with HPAV. His coagulation profile fluctuated with the following pertinent peak/nadir laboratory values and corresponding hospital day (HD): undetectable fibrinogen levels, d-dimer 8.89 mg/L and 7.43 mg/L, and INR 2.97 and 1.46 on HD zero and three, respectively. Other peak/nadir values included hemoglobin 9.7 g/dL and creatinine phosphokinase 2410 U/L on HD four and platelets 81 × 109/L on HD seven. The patient received a total of 30 vials of HPAV over 5 days and 1 unit of cryoprecipitate on HD six. Upon discharge on HD eight, laboratory studies were normalizing, except for platelets, and edema stabilized. This case describes an acute, recurrent, and prolonged venom-induced consumptive coagulopathy despite prompt administration and repeated doses of HPAV.

Kasabach-Merritt Syndrome: a case study of successful treatment with vincristine and propranolol.

Kasabach-Merritt syndrome is a rare condition, characterised by the presence of an enlarging vascular tumour associated with thrombocytopenia, microangiopathic haemolytic anaemia and consumptive coagulopathy. The syndrome manifests in infancy, with high morbidity and mortality rates. No standard guidelines have been established for the treatment of Kasabach-Merritt syndrome to date. To existing literature we add this report of a four-month-old female child with Kasabach-Merritt syndrome who was successfully treated with propranolol and vincristine. This drug combination helped reverse the severe thrombocytopenia as well as decrease in size of her haemangioma. Management of Kasabach-Merritt syndrome continues to be a challenge, with varying response to first line drugs. Early diagnosis and initiation of treatment in a closely monitored setting is essential to ensure good outcomes. Since this is a relatively rare condition and large studies are not feasible, documenting treatment experience for single cases or small series becomes even more important.

[Efficacy of Recombinant Thrombomodulin for Sepsis-Associated Disseminated Intravascular Coagulation Caused by Urinary Tract Infections].

Severe urinary tract infections occasionally cause sepsis and disseminated intravascular coagulation (DIC). We examined the efficacy of recombinant thrombomodulin (rTM) for treating DIC caused by urosepsis. We enrolled 40 patients who were diagnosed with DIC caused by urosepsis at our hospital between April 2018 and May 2022. Twenty-six patients were treated with rTM (rTM group), while 14 patients did not receive rTM (non-rTM group). The DIC score before treatment in the rTM group was significantly higher than that in the non-rTM group (P＜0.01). There was no significant difference in disease-specific survival between the two groups. There was a significant improvement in DIC scores on days 1-3 after administering rTM. However, the duration of DIC in the rTM group was significantly longer than that in the non-rTM group (P＝0.038). The administration of rTM may have benefits in patients with DIC caused by urosepsis.

Why anticoagulant studies on sepsis fail frequently --- start with SCARLET.

The Sepsis Coagulopathy Asahi Recombinant LE Thrombomodulin (SCARLET) trial has many defects, and thus cannot be the terminator of recombinant thrombomodulin (rTM). On the contrary, it provides sufficient evidence for further research. Based on analysis focusing on the failure of SCARLET and several previous anticoagulant studies, it is most important for new studies to grasp the following two points: (1) The enrolled cases should have sufficient disease severity and a clear standard for disseminated intravascular coagulation; (2) Heparin should not be used in combination with the investigated drugs. Multiple post-hoc analyses show that no combination of heparin will not increase the risk of thromboembolism. In fact, the combination of heparin can mask the true efficacy of the investigated drug. Due to the complexity of sepsis treatment and the limitations of clinical studies, the results of all treatment studies should be repeatedly verified, rather than be determined at one stroke. Some research conclusions contrary to disease physiology, pharmacology and clinical practice may be deceptive, and should be cautious rather than be simply accepted. On the other hand, the dissenting voices in the "consensus" scene are often well discussed by the authors and should be highly valued.

OPTIMAL PLASMA CONCENTRATION OF THROMBOMODULIN ALFA TO TREAT SEPSIS-INDUCED DISSEMINATED INTRAVASCULAR COAGULATION.

ABSTRACT: Thrombomodulin alfa (TM alfa) has been shown effective for treatment of disseminated intravascular coagulation (DIC) associated with sepsis, although the optimal therapeutic plasma concentration has not been clarified. In the present study, the plasma trough concentration of TM alfa in septic patients with DIC was determined, then the cutoff value for that concentration showing influence on treatment outcome was calculated using a receiver operating characteristic curve. With a cutoff value of 1,010, the area under the curve of the receiver operating characteristic was 0.669 (95% confidence interval, 0.530-0.808), with sensitivity of 0.458 and specificity of 0.882. To evaluate its accuracy, patients were divided into those above or below the cutoff value, and 90-day survival rates were compared. The above-cutoff group showed a significantly higher 90-day survival rate (91.7%) as compared with the below-cutoff group (63.4%) ( P = 0.017), with a hazard ratio of 0.199 (95% confidence interval, 0.045-0.871). Interestingly, the incidence of hemorrhagic adverse effects was not significantly different between the groups. Based on these results, the recommended plasma trough concentration of TM alfa for treatment of septic DIC is 1,010 ng/mL, which should minimize the risk of severe bleeding while maximizing the therapeutic effect.

Efficacy and safety of recombinant human soluble thrombomodulin in patients with sepsis-induced disseminated intravascular coagulation - A meta-analysis.

BACKGROUND: Recombinant human soluble thrombomodulin (rhTM) is used to treat sepsis-induced disseminated intravascular coagulation (DIC). However, no consistent clinical guidelines exist regarding the administration of rhTM in patients with sepsis-induced DIC. Therefore, we conducted this meta-analysis to evaluate the efficacy and safety of rhTM therapy in patients with sepsis-induced DIC. METHODS: EMBASE, PubMed, Scopus, Ichushi, and CINAHL databases were used to search for relevant articles that met the inclusion criteria of patients with sepsis-induced DIC treated with and without rhTM through November 2022. Mortality, DIC resolution, and incidence of bleeding complications were evaluated. DIC resolution was defined as the recovery from DIC after the start of DIC treatment. RESULTS: Of the 1697 citations identified for screening, 17 studies involving 2296 patients were included. Administering rhTM significantly reduced mortality (odds ratio (OR) 0.54, 95 % confidence interval (CI) 0.42-0.71) and improved DIC resolution (OR 2.88, 95 % CI 1.83-4.52). There were no significant differences in the incidence of bleeding complications between the rhTM and control groups (OR 0.92, 95 % CI 0.66-1.28). CONCLUSIONS: Our meta-analysis revealed that rhTM could reduce mortality and improve DIC resolution without increasing the risk of bleeding in patients with sepsis-induced DIC. Our findings suggest that rhTM is a relatively effective and safe anticoagulant for the treatment of sepsis-induced DIC. SUMMARY: Recombinant human soluble thrombomodulin reduced mortality without increasing the bleeding risk in the treatment of sepsis-induced disseminated intravascular coagulation.

Bleeding events associated with recombinant human soluble thrombomodulin, classified according to renal function, in sepsis-induced disseminated intravascular coagulation.

OBJECTIVE: Recombinant human soluble thrombomodulin (rhsTM) is a therapeutic agent for sepsis-induced disseminated intravascular coagulation (DIC) and is associated with bleeding events. rhsTM is a renal excretion drug; however, information on the role of rhsTM in renal function is limited. MATERIALS AND METHODS: In this retrospective observational study, we assessed rhsTM-associated bleeding events according to the renal function of patients with sepsis-induced DIC. We analyzed the data of 79 patients administered a standard-dose of rhsTM for sepsis-induced DIC, at a single center. Patients were classified based on estimated glomerular filtration rate (eGFR). We measured fresh bleeding events following rhsTM administration, DIC score efficacy, and 28-day mortality. RESULTS: Fresh bleeding events were observed in 15 patients, with a significant difference in the eGFR, platelet count, and DIC scores. Furthermore, fresh bleeding events tended to increase with the deterioration of renal function (p = 0.039). The DIC scores in all renal function groups decreased after -rhsTM administration. Additionally, the 28-day mortality was less than 30% in all groups. CONCLUSION: Our results indicate that the effectiveness of the standard-dose of rhsTM is not related to renal function. However, standard-dose rhsTM therapy could potentially increase the risk of adverse bleeding events with severe renal function equivalent to G5.

Slowly Progressive Bone Marrow Metastasis of Gastric Cancer Followed-up Without Treatment.

BACKGROUND/AIM: Bone marrow metastasis (BMM) of gastric cancer (GC) is complicated by disseminated intravascular coagulation syndrome (DIC), which is more prominent in poorly differentiated carcinoma. This is one of the first case reports of a slowly progressing BMM of GC after approximately 1 year of follow-up without treatment. CASE REPORT: A 72-year-old woman underwent total gastrectomy and splenectomy for GC in February 2012. The pathological diagnosis was that of a moderately differentiated adenocarcinoma. Five years later in December 2017, she developed anemia; however, its cause remained unknown. Due to worsening of the anemia, the patient visited the Kakogawa Central City Hospital in October 2018. Bone marrow biopsy revealed an infiltration of caudal type homeobox 2-positive cancer cells, and our diagnosis was BMM of GC. There was no DIC. The incidence of BMM is high in well- or moderately differentiated breast cancer but rarely causes DIC. CONCLUSION: As with breast cancer, in moderately differentiated cancer cells, BMM of GC may progress slowly after the appearance of symptoms without causing DIC.

[Devil with angel wings - when vitamin A saves lives]. / Teufel mit Engelsflügeln ­ wenn Vitamin A Leben rettet.

ANAMNESIS AND CLINICAL EXAMINATION: A 40-year-old male patient presented to our emergency department with a new onset of hemorrhagic diathesis. Clinically, there were marked bleeding stigmata with extensive ecchymosis in the thigh area and oral mucosal hemorrhage with otherwise general well-being. DIAGNOSTICS: The coagulation diagnostics performed were consistent with the picture of disseminated intravascular consumption coagulopathy. Microscopic blood count also revealed 74% morphologically atypical promyelocytes. DIAGNOSIS, THERAPY, AND CLINICAL COURSE: Bone marrow investigation confirmed the diagnosis of a microgranular variant of acute promyelocytic leukemia. In addition to coagulation optimization, therapy with all-trans retinoic acid (ATRA) was initiated immediately. Subsequently, arsenic trioxide (ATO) and the anthracycline idarubicin were added. No severe complications occurred in the following course of treatment. Moreover, the patient is currently in complete remission regarding acute promyelocytes leukemia. CONCLUSIONS: Acute promyelocytic leukemia accounts for approximately 10-15% of all acute myeloid leukemias. Often, association with marked coagulation abnormalities due to disseminated intravascular consumption coagulopathy, which is present at diagnosis, APL becomes fatal if untreated. Rapid therapy initiation with ATRA and coagulation optimization, initiated as soon as the diagnosis is suspected, are crucial for prognosis.

Effect of Anticoagulant Versus Non-Anticoagulant Therapy on Mortality of Sepsis-Induced Disseminated Intravascular Coagulation: A Systematic Review and Meta-Analysis.

BACKGROUND: Sepsis is a syndrome of severe systemic inflammatory response. When combined with disseminated intravascular coagulation, mortality is increased. The need for anticoagulant therapy is still the focus of debate. METHODS: PubMed, Embase, Cochrane Library, and Web of Science were searched. Adult patients with sepsis-induced disseminated intravascular coagulation were included in this study. All-cause mortality as efficacy and serious bleeding complications as adverse effect were measured as primary outcomes. Methodological quality of included studies were assessed using the Methodological Index for Non-randomized Studies (MINORS). Meta-analysis was performed using R software (version 3.5.1) and Review Manager (version 5.3.5). RESULTS: There were nine eligible studies with 17,968 patients included. There were no significant reductions in mortality between the anticoagulant group and the non-anticoagulant group (RR, 0.89; 95% CI, 0.72-1.10; P = 0.27). The DIC resolution rate in the anticoagulation group has a statistically significant increase compared with the control group [OR: 2.62, 95% CI (1.54-4.45), P < 0.05]. And there was no significant difference in bleeding complications between the two groups (RR, 1.27; 95% CI, 0.77-2.09; P = 0.69). SOFA score reduction did not change significantly between the two groups (P = 0.13). CONCLUSIONS: Our study observed no significant benefit of anticoagulant therapy on mortality of sepsis-induced DIC. Anticoagulation therapy can promote DIC resolution in sepsis-induced DIC. In addition, anticoagulant therapy does not increase the risk of bleeding in these patients.

Communication from the Scientific and Standardization Committee of the International Society on Thrombosis and Haemostasis on sepsis-induced coagulopathy in the management of sepsis.

Disseminated intravascular coagulation (DIC) is a life-threatening complication in sepsis and other critical conditions. The International Society on Thrombosis and Haemostasis (ISTH) released the diagnostic criteria for overt DIC in 2001. Since then, ISTH overt DIC has been used as the global standard criterion for a decompensated stage of DIC. Because detecting an earlier stage of DIC would be useful for therapeutic considerations, the scientific standardization committees of the ISTH introduced the sepsis-induced coagulopathy (SIC) scoring system in 2019. The SIC scoring system is specifically designed to detect the compensated phase of DIC in sepsis, which can lead to overt DIC with disease progression. Studies examining the performance of the SIC scoring system have reported its usefulness over the past 5 years. The reported incidence of SIC was approximately 60% in patients with sepsis, which was twice as much as that of overt DIC. Almost all patients with overt DIC were diagnosed with SIC earlier. The reported mortality of SIC was ≥30% and, thus, can be used for patient selection for anticoagulant therapy. Despite the limited data, some continue to suggest the potential efficacy of anticoagulant therapy in patients with SIC. Although heparin, antithrombin, and thrombomodulin are the candidates for anticoagulation, none of them have proven to be effective with robust evidence, and future trials are warranted.

Successful Management of Prolonged Thrombocytopenia After Surgery for Abdominal Aortic Aneurysm With Disseminated Intravascular Coagulation.

We report a case of an infrarenal abdominal aortic aneurysm that developed acute onset thrombocytopenia and disseminated intravascular coagulation (DIC) after a previous coronary artery bypass grafting. Open surgical intervention was successfully performed for the treatment of aortic aneurysm; however, thrombocytopenia and enhanced-fibrinolytic-type DIC were prolonged even after the surgery, and improved after Helicobacter pylori eradication therapy and medication with warfarin and oral tranexamic acid. Surgical intervention alone was not effective as a treatment for DIC associated with aortic aneurysm, and multidisciplinary management was necessary for the optimization of the coagulation and fibrinolytic systems, even after successful surgery.

Effect of Anticoagulant/Antifibrinolytic Combination Therapy on Enhanced Fibrinolytic-Type Disseminated Intravascular Coagulation in End-of-Life Stage Solid Tumor Patients.

Thrombotic disorders such as venous thromboembolism and disseminated intravascular coagulation (DIC) are known complications of solid tumors. To date, no reports have described the treatment of enhanced fibrinolytic-type DIC caused by end-of-life stage solid tumors. We encountered three cases of end-of-life stage solid tumors complicated by enhanced fibrinolytic-type DIC with severe bleeding symptoms. In all three cases, bleeding symptoms improved dramatically after intervention for enhanced fibrinolytic-type DIC with heparin(s) and tranexamic acid. Improvements in abnormal coagulation test results were also seen and the need for platelet concentrate transfusion and fresh frozen plasma infusion was able to be eliminated. However, one patient developed multiple cerebral infarctions. In the future, further studies to investigate the need for intervention in enhanced fibrinolytic-type DIC caused by end-of-life stage solid tumors and suitable treatment strategies are warranted.

Clinical impact of recombinant thrombomodulin administration on disseminated intravascular coagulation due to severe acute cholangitis (Recover-AC study).

BACKGROUND AND AIM: Recombinant thrombomodulin (rhTM) is potentially effective in the treatment of disseminated intravascular coagulation (DIC). Several studies related to drugs for the treatment of acute cholangitis have shown negative results in improvement of overall survival (OS) with rhTM. The aim of this multicenter study was to evaluate the clinical effectiveness of rhTM in patients with acute cholangitis and sepsis-induced DIC who underwent biliary drainage. METHODS: A total of 284 consecutive patients, who were complicated with sepsis-induced DIC due to severe acute cholangitis, were included (rhTM group, n = 173; non-rhTM, n = 111) in this study. The primary outcome was the DIC resolution rate at 7 days after starting treatment. The 28-day survival rate was secondarily evaluated. RESULTS: DIC scores in the rhTM group improved significantly compared with the non-rhTM group on day 7 (P = .020). According to multivariate analysis, etiology of cholangitis (malignant, HR 2.28), rhTM (non-administration, HR 4.13), and DIC score (≥5, HR 2.46) were significant factors associated with failed DIC resolution on day 7. Propensity score matching created 103 matched pairs. Survival rate at day 28 was significantly higher in rhTM group (94.3%) compared with non-rhTM group (82.6%; P = .048) after propensity score matching. rhTM (non-administration, HR 2.870), DIC score (≥5, HR 2.751), and APACHE II score (≥20, HR 9.310) were significant factors associated with decreasing survival rate at day 28. CONCLUSION: In conclusion, rhTM seemed to improve patient survival, but future studies should only include patients with benign or malignant disease and should be performed according to APACHE II scores.

Prothrombinex®-VF in chronic liver disease: Friend or foe?

OBJECTIVE: Management of coagulopathy in chronic liver disease (CLD) poses a challenge for critical care physicians. Prothrombinex®-VF is a low-volume product with rapid onset of action. Evidence for its efficacy and safety in CLD is limited and cases of acute intravascular coagulation and fibrinolysis (AICF) and/or disseminated intravascular coagulation (DIC) have been reported. Our objective was to evaluate the role of Prothrombinex®-VF in reversal of coagulopathy and the incidence AICF/DIC, thromboembolic events and mortality. METHODS: This was a retrospective, multi-centre study of Prothrombinex®-VF use in CLD across 11 hospitals over a 2-year period, excluding those on therapeutic anticoagulation. Patients were subclassified into acute on chronic liver failure (ACLF), acute decompensation (ADC) and compensated cirrhosis. Reversal of coagulopathy was defined as international normalised ratio (INR) <1.5× upper limit normal (ULN), prothrombin time <1.5× ULN, activated partial thromboplastin time <1.5× ULN and fibrinogen >1 g/L. Markers of AICF/DIC were recorded. RESULTS: Thirty CLD patients were included, and the median model for end-stage liver disease score was 23.5. Acute bleeding was the most common indication for Prothrombinex®-VF (60%). All had baseline coagulopathy and the majority did not achieve reversal. Key indicators of AICF/DIC were mainly observed in those with ACLF; bleeding from mucosa or lines (53%), worsening hypofibrinogenaemia (60%), worsening thrombocytopaenia (60%). The ADC and compensated cirrhosis groups were relatively unaffected. Incidence of venous thromboembolism was 6%. Overall mortality was 43% and 70% in ACLF. CONCLUSION: Prothrombinex®-VF did not lead to meaningful reversal of coagulopathy and should be used with caution in CLD. Patients with ACLF were more likely to develop AICF/DIC following Prothrombinex®-VF, although the association is uncertain. Further studies are needed to evaluate the safety and efficacy of Prothrombinex®-VF use in CLD.
