Abstract
Introduction. As a result of portal hypertension (sequestration of platelets in an enlarged spleen) and liver failure (decreased production of thrombopoietin in the liver) in liver cirrhosis, thrombocytopenia develops, which is associated with the risk of periprocedural/perioperative bleeding complications. There are still unresolved questions regarding risk stratification of bleeding complications, the prognostic role of thrombocytopenia, as well as the need for treatment of thrombocytopenia and its methods.Materials and methods. The Russian Scientific Liver Society selected a panel of experts in the field of therapeutic and surgical hepatology, hematology, transfusion medicine to make reasoned statements and recommendations on the issue of treatment of thrombocytopenia before elective surgery / invasive procedures in patients with liver cirrhosis.Results. Relevant clinical issues were determined based on the PICO principle (patient or population, intervention, comparison, outcome). The Delphi panel made five questions and gave reasoned answers, framed as ‘clinical practice recommendations and statements’ with evidence-based comments. The questions and statements were based on the results of search and critical analysis of medical literature using keywords in English- and Russian-language databases. The formulated questions could be combined into four categories: bleeding risk stratification, the prognostic value of thrombocytopenia, the necessity and methods of thrombocytopenia drug correction, and bleeding risk reduction.Conclusions. The results of experts' work are directly related to high-quality management of patients with liver cirrhosis and thrombocytopenia, who have scheduled invasive procedures/surgery. Thus, this recommendations and statements can be used in clinical practice.

J Clin Exp Hepatol 2024; 14:101291. [PMID: 38544766 PMCID: PMC10964076 DOI: 10.1016/j.jceh.2023.10.002] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/13/2023] [Accepted: 10/01/2023] [Indexed: 06/24/2024] Open
Abstract
BACKGROUND Cirrhosis is a significant cause of morbidity and mortality globally and in India. This systematic review and meta-analysis aimed to ascertain the etiological spectrum and changing trends of cirrhosis in India. METHODS We searched electronic databases, including Pubmed/Medline, Scopus, and Embase. We included original studies that reported the etiology of cirrhosis in the Indian population. RESULTS We included 158 studies (adults: 147, children: 11). The overall pooled estimate of alcohol as a cause of cirrhosis in adults was 43.2% (95% confidence interval (CI) 39.8-46.6%; I2 = 97.8%), followed by nonalcoholic fatty liver disease (NAFLD)/cryptogenic in 14.4%, 95% CI (11.7-17.3%; I2 = 98.4%), hepatitis B virus (HBV) in 11.5%, 95% CI (9.8-13.3%; I2 = 96.6%), and hepatitis C virus (HCV) in 6.2%, 95% CI (4.8-7.8%; I2 = 97.2%) of the included patients. The most common cause of cirrhosis in all zones was alcohol-related. Comparison of etiologies over time revealed a reduction in the viral hepatitis-related and an increase in the proportion of alcohol-related and NAFLD/cryptogenic-related cirrhosis. The overall pooled estimates of various etiologies in children were: HBV in 10.7%, 95% CI (4.6-18.7%; I2 = 91.0%), NAFLD/Cryptogenic in 22.3%, 95% CI (9.0-39.2%; I2 = 96.7%), and HCV in 2.0%, 95% CI (0.0-8.5%; I2 = 94.6%). CONCLUSIONS Alcohol is the most common etiology of cirrhosis in adults in India. The proportions of alcohol and NAFLD-related cirrhosis are increasing, and those of viral hepatitis-related cirrhosis are reducing. The results of our meta-analysis will help formulate health policies and the allocation of resources.

Abstract
Coagulation management in the patient with cirrhosis has undergone a significant transformation since the beginning of this century, with the concept of a rebalancing between procoagulant and anticoagulant factors. The paradigm that patients with cirrhosis have a greater bleeding tendency has changed, as a result of this rebalancing. In addition, it has brought to light the presence of complications related to thrombotic events in this group of patients. These guidelines detail aspects related to pathophysiologic mechanisms that intervene in the maintenance of hemostasis in the patient with cirrhosis, the relevance of portal hypertension, mechanical factors for the development of bleeding, modifications in the hepatic synthesis of coagulation factors, and the changes in the reticuloendothelial system in acute hepatic decompensation and acute-on-chronic liver failure. They address new aspects related to the hemorrhagic complications in patients with cirrhosis, considering the risk for bleeding during diagnostic or therapeutic procedures, as well as the usefulness of different tools for diagnosing coagulation and recommendations on the pharmacologic treatment and blood-product transfusion in the context of hemorrhage. These guidelines also update the knowledge regarding hypercoagulability in the patient with cirrhosis, as well as the efficacy and safety of treatment with the different anticoagulation regimens. Lastly, they provide recommendations on coagulation management in the context of acute-on-chronic liver failure, acute liver decompensation, and specific aspects related to the patient undergoing liver transplantation.

Abstract
In hepatorenal syndrome-acute kidney injury (HRS-AKI), accurate and early diagnosis is crucial. HRS is a severe condition seen in advanced cirrhosis, requiring prompt recognition and proper management to enhance patient outcomes. Diagnosis of HRS-AKI relies on serum creatinine elevations, similar to other AKI cases in cirrhosis. However, distinguishing HRS-AKI from other renal impairments in these patients can be challenging. Biomarkers and clinical criteria aid in diagnosis and guide treatment. The management of HRS-AKI initially involves improving the haemodynamic profile using albumin and vasoconstrictors like terlipressin, a synthetic vasopressin analogue. Despite some reports linking terlipressin to increased adverse events compared with norepinephrine, it remains the preferred choice in HRS-AKI and acute-on-chronic liver failure due to its faster, stronger response and improved survival. Additional therapies like midodrine (alpha-1 adrenergic agonist), octreotide (somatostatin analogue) and transjugular intrahepatic portosystemic shunt are proposed as adjuvant treatments for HRS-AKI, aiming to improve vasoconstriction and renal blood flow. However, these adjunctive therapies cannot replace the definitive treatment for HRS-AKI-liver transplantation (LT). In cases unresponsive to medical management, LT is the only option to restore liver function and improve renal outcomes. Current evidence favours combined liver and kidney transplantation (CLKT) in certain situations. This review aims to evaluate the present evidence and recommendations on AKI in patients with cirrhosis, the pathophysiology of HRS-AKI, different treatments and indications for LT and CLKT. Understanding the complexities of managing HRS-AKI is crucial for optimising patient care and achieving better outcomes in this challenging clinical setting.

Abstract
Hospitalised patients with decompensated cirrhosis are in a rebalanced haemostatic state due to a parallel decline in both pro- and anti-haemostatic pathways. However, this rebalanced haemostatic state is highly susceptible to perturbations and may easily tilt towards hypocoagulability and bleeding. Acute kidney injury, bacterial infections and sepsis, and progression from acute decompensation to acute-on-chronic liver failure are associated with additional alterations of specific haemostatic pathways and a higher risk of bleeding. Unfortunately, there is no single laboratory method that can accurately stratify an individual patient's bleeding risk and guide pre-procedural prophylaxis. A better understanding of haemostatic alterations during acute illness would lead to more rational and individualised management of hospitalised patients with decompensated cirrhosis. This review will outline the latest findings on haemostatic alterations driven by acute kidney injury, bacterial infections/sepsis, and acute-on-chronic liver failure in these difficult-to-treat patients and provide evidence supporting more tailored management of bleeding risk.

Abstract
Over the last decades, individualized approaches and a better understanding of coagulopathy complexity in end-stage liver disease (ESLD) patients has evolved. The risk of both thrombosis and bleeding during minimally invasive interventions or surgery is associated with a worse outcome in this patient population. Despite deranged quantitative and qualitative coagulation laboratory parameters, prophylactic coagulation management is unnecessary for patients who do not bleed. Transfusion of red blood cells (RBCs) and blood products carries independent risks for morbidity and mortality, including modulation of the immune system with increased risk for nosocomial infections. Optimal coagulation management in these complex patients should be based on the analysis of standard coagulation tests (SCTs) and viscoelastic tests (VETs). VETs represent an individualized approach to patients and can provide information about coagulation dynamics in a concise period of time. This narrative review will deliver the pathophysiology of deranged hemostasis in ESLD, explore the difficulties of evaluating the coagulopathies in liver disease patients, and examine the use of VET assays and management of coagulopathy using coagulation factors. Methods: A selective literature search with PubMed as the central database was performed with the following.

Abstract
INTRODUCTION Patients with cirrhosis are at risk of both thrombotic and hemorrhagic events. Traditional hemostatic tests are inadequate to assess the complex and fragile balance of hemostasis in this setting, especially in advanced stages of disease such as decompensated cirrhosis or acute on chronic liver failure (ACLF). Furthermore, the indiscriminate use of pro-hemostatic agents for prophylaxis and treatment of bleeding episodes is still debated and often contraindicated. Alongside, splanchnic, and peripheral thrombotic events are frequent in this population and require management that involves a careful balance between risks and benefits of antithrombotic therapy. AREAS COVERED This review aims to address the state of the art on the clinical management of the hemostatic balance of cirrhosis in terms of established knowledge and future challenges. EXPERT OPINION The old paradigm of cirrhosis as a naturally anticoagulated condition has been challenged by more sophisticated global tests of hemostasis. Integrating this information in the clinical decision-making is still challenging for physicians and experts in hemostasis.

Abstract
The prevention and management of bleeding and thrombosis in patients with cirrhosis poses several difficult clinical questions. These Clinical Practice Guidelines have been developed to provide practical guidance on debated topics, including current views on haemostasis in liver disease, controversy regarding the need to correct thrombocytopenia and abnormalities in the coagulation system in patients undergoing invasive procedures, and the need for thromboprophylaxis in hospitalised patients with haemostatic abnormalities. Multiple recommendations in this document are based on interventions that the panel feels are not useful, even though widely applied in clinical practice.

Abstract
Background The optimal prophylactic preprocedural management of patients with coagulopathy due to liver disease is not known. Objectives Our objective was to compare the efficacy and safety of fresh frozen plasma (FFP) with prothrombin complex concentrate (PCC) in the preprocedural management of patients with coagulopathy of liver disease. Methods We conducted a systematic review to examine published evidence regarding treatment with FFP or PCC in adults with coagulopathy of liver disease undergoing an invasive procedure. Direct comparisons and single-arm studies were eligible. Efficacy outcomes included major bleeding, mortality, and correction of prothrombin time (PT) and/or international normalized ratio (INR). Safety outcomes included thrombosis and transfusion-related complications. Results A total of 95 articles were identified for full-text review. Nine studies were eligible and included in the review. No randomized trials comparing FFP versus PCC were identified. Only two studies directly compared FFP versus PCC. In these studies, PCC appeared to result in higher rates of correction of PT/INR, but bleeding outcomes were not different. In the single-arm studies, bleeding events appeared low overall. Volume overload was the most common recorded adverse event in patients receiving FFP. Thromboembolic events occurred rarely, but exclusively in the PCC group. Due to heterogeneity in study definitions and bias, meta-analysis was not possible. Our study found no evidence to favor a specific product over another. Conclusions Insufficient data exist on the effects of FFP versus PCC administration before invasive procedures in patients with coagulopathy of liver disease to make conclusions with respect to relative efficacy or safety.

BACKGROUND Standard coagulation parameters are used to guide prophylactic blood product transfusion prior to invasive procedures in cirrhotic patients despite limited high-quality evidence. AIMS We aimed to describe coagulation parameters and prophylactic blood product use in cirrhotic patients having invasive procedures, and the influence of both on periprocedural bleeding. METHODS We conducted a cohort study of cirrhotic patients undergoing invasive procedures at a referral hospital. Procedures were classified into low or moderate-high bleeding risk. Prophylactic blood component was defined as fresh frozen plasma, cryoprecipitate or platelet transfusion prior to procedures. Univariate and multivariate logistic regression was performed to identify factors associated with procedure-related bleeding. RESULTS We identified 566 procedures in 233 cirrhotic patients. Prophylactic blood product was given before 16% of high-risk and 11% of low-risk procedures (P = 0.18). Eight (8.3%) high-risk procedures were complicated by postprocedural bleeding, six of which occurred in patients without significant coagulopathy. The bleeding rate for low-risk procedures was 0.4%. For patients with international normalized ratio >1.5, platelet count <50 x 109/L, or both, the rate of bleeding was comparable between those given and not given prophylactic blood products (3.1 vs. 1.9%; P = 0.63). After adjusting for age, sex, platelet count, international normalized ratio, acute kidney injury, sepsis and model of end-stage liver disease, the only factor significantly predicting procedure-related bleeding was the procedural bleeding risk category (P < 0.01). CONCLUSIONS Procedure-related bleeding in cirrhotic patients cannot be accurately predicted by INR or platelet count, nor prevented by blood component prophylaxis using these parameters. Procedure-related bleeding is best predicted by the bleeding risk status of procedures.

Abstract
BACKGROUND Gaps of knowledge still exist about the potential association between severe thrombocytopenia and increased risk of procedure-associated bleeding in patients with liver disease. METHODS In this narrative review, we aimed at examining the association between procedure-related bleeding risk and platelet count in patients with cirrhosis and severe thrombocytopenia in various settings. We updated to 2020 a previously conducted literature search using MEDLINE/PubMed and EMBASE. The search string included clinical studies, adult patients with chronic liver disease and thrombocytopenia undergoing invasive procedures, any interventions and comparators, and haemorrhagic events of any severity as outcome. RESULTS The literature search identified 1276 unique publications, and 15 studies met the inclusion criteria and were analysed together with those identified by the previous search. Most of the new studies included in our analysis did not assess the association between post-procedural bleeding risk and platelet count alone in patients with chronic liver disease. Furthermore, some results could have been biased by prophylactic platelet transfusions. A few studies found that severe thrombocytopenia may be predictive of bleeding following percutaneous liver biopsy, dental extractions, percutaneous ablation of liver tumours and endoscopic polypectomy. CONCLUSIONS Currently available literature cannot support definitive conclusions about the appropriate target platelet counts to improve the risk of bleeding in cirrhotic patients who underwent invasive procedures; moreover, it showed enormous variability in the use of prophylactic platelet transfusions.

Abstract
BACKGROUND Alterations in normal coagulation and hemostasis are critical issues that require special attention in the neurosurgical patient. These disorders pose unique challenges in the management of these patients who often have concurrent acute ischemic and hemorrhagic injuries. Although neurosurgical intervention in such cases may be unavoidable and potentially life-saving, these patients should be closely observed after instrumentation. CASE DESCRIPTION A 57-year-old male with liver cirrhosis secondary to amyloid light-chain amyloidosis was admitted to the intensive care unit for the management of delayed hydrocephalus. An external ventricular drain (EVD) was placed for the treatment and monitoring of hydrocephalus. Five days after EVD placement, a head computed tomography scan revealed a tract hemorrhage. However, on repeated imaging, the size of the hemorrhage continued to increase despite aggressive blood pressure control and several doses of phytonadione. Extensive coagulopathy workup was remarkable for low factor VII levels. In that setting, recombinant activated factor VII was administered to normalize factor VII levels, and the tract hemorrhage stabilized. CONCLUSION To the best of our knowledge, this is the first case of spontaneous hemorrhage after EVD placement in the setting of liver cirrhosis-associated factor VII deficiency. Our case highlights the importance of identifying coagulation disorders in neurosurgical patients at high risk for coagulopathy and closely monitoring them postoperatively.

Abstract
BACKGROUND/AIMS This study aimed to provide supporting evidence for prevention and prognostic evaluation of bleeding complications in the early stage by exploring the risk and predicting factors in patients with acute-on-chronic liver failure (ACLF). MATERIALS AND METHODS A total of 101 hospitalized patients with ACLF were retrospectively included from January 1, 2014 to December 31, 2015. The patients were divided into bleeding (n=38) and nonbleeding groups (n=63). Demographic data and laboratory tests were recorded and compared between the two groups. The incidence, risk factors, and prognosis of bleeding complications among patients with ACLF were investigated. RESULTS A total of 38 cases (37.62%) had bleeding complications: 26 (25.74%) were spontaneous and 12 (11.88%) were postprocedural. Patients with bleeding complications had lower platelet (p=0.008), fibrinogen (p<0.001), factor V (p=0.001), and factor VII (p=0.026) levels; higher serum creatinine levels (p=0.004); and a higher proportion of cirrhosis (p=0.013). Logistic regression analysis showed that cirrhosis (odds ratio=3.251, p=0.046), fibrinogen level (odds ratio=0.352, p=0.007), and factor VII level (odds ratio=0.951, p=0.011) contributed to the development of bleeding complications. A subgroup analysis of invasive manipulation-induced bleeding complications showed lower levels of factors V (p=0.018) and VII (p=0.021) in the postprocedural bleeding group. Follow-up studies showed that the nonbleeding group had a higher survival rate than the bleeding group at day 90 (73.33% versus 51.85%, p=0.040). CONCLUSION Liver cirrhosis, lower levels of fibrinogen, and major coagulation factor activity in patients with ACLF were associated with an elevated risk of bleeding events during hospitalization, which further impaired the 90-day survival rate.

Systematic review with meta-analysis: abnormalities in the international normalised ratio do not correlate with periprocedural bleeding events among patients with cirrhosis. Aliment Pharmacol Ther 2020; 52:1298-1310.

Abstract
BACKGROUND Cirrhotic coagulopathy is a delicate interplay comprising deficiencies of both procoagulant and anticoagulant factors. AIM To identify the relationship between international normalised ratio [INR] with periprocedural bleeding risk among patients with cirrhosis. METHODS Following a thorough database search of the primary literature, 29 studies were targeted for analysis, including 13 276 patients with cirrhosis undergoing indicated procedures. RESULTS There was no significant association between periprocedural bleeding events and pre-procedural INR [pooled odds ratio 1.52; 95% CI 0.99, 2.33; P = 0.06]. Furthermore, there was no significant difference in mean INR [pooled mean difference 0.05; 95% CI -0.03, 0.13; P = 0.23] upon comparison of patients who either did or did not experience a periprocedural bleeding event. Significant heterogeneity among some studies was primarily fuelled by significant subgroup effects of both specific procedure types performed. Additionally, there were markedly inconsistent transfusion practices across studies. CONCLUSIONS INR fails to serve as a significant correlate for periprocedural bleeding events among patients with cirrhosis. Ideally, these new findings will help serve as a springboard for future studies, as well as to minimize transfusion of blood products, which command a myriad of adverse effects among patients with cirrhosis.

Abstract
Thrombocytopenia is a frequent complication in patients with cirrhosis. As many as 84% of patients with cirrhosis have thrombocytopenia, and it is an independent variable indicative of advanced disease and poor prognosis. Although there is great concern that it may aggravate bleeding during surgical procedures, there is limited evidence to inform decisions regarding the treatment of cirrhotic patients with thrombocytopenia undergoing invasive procedures. Finally, there is evidence that platelets play a significant role in liver regeneration. In this report, the clinical implications of thrombocytopenia in cirrhotic patients are reviewed. The utility of platelet counts in the prognosis of cirrhosis and relationship to complications of advanced liver disease, including portal hypertension, esophageal varices, and hepatocellular carcinoma. The impact of low platelet counts on bleeding complications during invasive procedures is outlined. Finally, the role of platelets and potential adverse impact in liver regeneration is reviewed.

Abstract
OBJECTIVE Thromboelastography (TEG) may provide rapid and clinically important coagulation information in acutely ill patients with chronic liver disease (CLD). Our objective was to describe the relationship between TEG and conventional coagulation tests (CCTs), which has not been previously explored in this population. METHODS In acutely ill patients with severe CLD (Child-Pugh score > 9, category C), we conducted a prospective observational study investigating coagulation assessment as measured by both CCTs and TEG. We used quantile regression to explore 30 associations between TEG parameters and corresponding CCTs. We compared TEG and CCT measures of coagulation initiation, clot formation, clot strength, and fibrinolysis. RESULTS We studied 34 patients on a total of 109 occasions. We observed inconsistent associations between TEG and CCT measures of coagulation initiation: TEG (citrated kaolin [CK] assay) standard reaction time and international normalized ratio: R 2 = 0.117 (P = .044). Conversely, there were strong and consistent associations between tests of clot formation: TEG (CK) kinetics time and fibrinogen: R 2 = 0.202 (P < .0001) and TEG (CK) α angle and fibrinogen 0.263 (P < .0001). We also observed strong associations between tests of clot strength, specifically TEG MA and conventional fibrinogen levels, across all TEG assays: MA (CK) and fibrinogen: R 2 = 0.485 (P < .0001). There were no associations between TEG and D-dimer levels. CONCLUSIONS In acutely ill patients with CLD, there are strong and consistent associations between TEG measures of clot formation and clot strength and conventional fibrinogen levels. There are weak and/or inconsistent associations between TEG and all other conventional measures of coagulation.

Abstract
This consensus statement on chronic hepatitis (CH) in dogs is based on the expert opinion of 7 specialists with extensive experience in diagnosing, treating, and conducting clinical research in hepatology in dogs. It was generated from expert opinion and information gathered from searching of PubMed for manuscripts on CH, the Veterinary Information Network for abstracts and conference proceeding from annual meetings of the American College of Veterinary Medicine and the European College of Veterinary Medicine, and selected manuscripts from the human literature on CH. The panel recognizes that the diagnosis and treatment of CH in the dog is a complex process that requires integration of clinical presentation with clinical pathology, diagnostic imaging, and hepatic biopsy. Essential to this process is an index of suspicion for CH, knowledge of how to best collect tissue samples, access to a pathologist with experience in assessing hepatic histopathology, knowledge of reasonable medical interventions, and a strategy for monitoring treatment response and complications.

Abstract
Over the next decade, there is a predicted shortage of nonmalignant hematologist to maintain the workforce in the United States. To address this, the American Society of Hematology described the creation of the healthcare systems-based hematologist (SBH). The role of SBH has the potential to provide high-value, cost-conscious care to the healthcare system. In 2011, an Anticoagulation and Bleeding Management Medical Directorship position for a SBH was created at our healthcare system. We described our 6-year experience as SBH at a 750-bed tertiary academic medical center to improve clinical outcomes while reducing costs. Via four different initiatives, we were able to provide high-value, cost-conscious care as SBH by reducing cost of heparin-induced thrombocytopenia management, optimizing blood product utilization using goal-directed algorithms, reducing inappropriate thrombophilia testing and improving inferior vena cava filter retrieval rates. To ensure continuing success as a SBH, business plans need to include education, enforcement, monitoring, feedback, validation of safety and outcomes and a shared vision among leadership.

Abstract
Background and Objectives Hepatic encephalopathy (HE) research has long been impeded by the vague definition of this disabling complication of liver failure. This article provides an overview of the etiology and impact of HE on neuromuscular functions as well as its role in the development of infections and anemia. Materials and Methods This was a descriptive study conducted in 36 patients with HE. Close monitoring of these patients was done by checking on several parameters. Results The etiological distribution: alcohol (67%), hepatitis C virus (HCV; 17%), HCV and alcohol (8%), hepatitis B virus (HBV; 3%), HBV and alcohol (3%), HBV and HCV (6%), and cryptogenic (3%). The laboratory results indicated an elevation of De Ritis level in 69% of cases and in 92% of total bilirubin values. The Halstead-Reitan (H-R) test score with regards to gender indicated that more than half of the patients had a score of 2, while only few cases received the scores 3 and 4. The frequency of H-R score with regards to Child-Pugh score showed the significant preponderance of Child-Pugh score of 7–9 (B): 58.3% compared to others groups of results, and these results indicated patients’ poor prognosis. Conclusion Findings showed the preponderance of female patients towards developing HE and the poor survival rate of patients older than 65 years. Alcohol and hepatitis C were the main causes associated with the development of HE. The neurological assessment marked the preponderance of Child-Pugh grades B and C and also the prevalence in female patients with neuropsychological disabilities through the assessment of H-R test.

Abstract
BACKGROUND/AIM Bleeding risk among patients with acute or chronic liver disease after invasive procedures is a common concern in clinical practice. This retrospective study aimed to explore whether the presence of coagulopathy increased the risk of major bleeding after invasive procedures in cirrhosis. PATIENTS AND METHODS A total of 874 cirrhotic patients underwent invasive procedures. Coagulopathy was defined as international normalized ratio (INR) ≥1.5 and/or platelets (PLTs) ≤50 × 109/L. Severe thrombocytopenia was defined as PLTs ≤ 50 × 109/L. Invasive procedures, major bleeding after invasive procedures, and in-hospital deaths were recorded. RESULTS In all, 296 patients (33.9%) had coagulopathy. Major bleeding after invasive procedures occurred in 21 patients (2.4%). Major bleeding after invasive procedures was more frequent in patients with coagulopathy than those without coagulopathy (4.1% vs 1.6%, P = 0.023). Major bleeding after invasive procedures was more frequent in patients with severe thrombocytopenia than those without severe thrombocytopenia (4.9% vs 1.6%, P = 0.008). Incidence of major bleeding after invasive procedures was not significantly different between patients with INR ≥ 1.5 and INR < 1.5 (4.5% vs 2.0%, P = 0.065). Patients with INR ≥1.5 had a significantly higher in-hospital mortality than those with INR < 1.5 (6.4% vs 1.3%, P < 0.001). CONCLUSION Severe thrombocytopenia significantly increased the risk of major bleeding after invasive procedures in cirrhosis. INR ≥ 1.5 significantly increased in-hospital mortality.

Abstract
BACKGROUND AND AIMS Conventional coagulation tests (CCTs) in patients with cirrhosis only assess procoagulant factors and are poor predictors of bleeding risk. In spite of this knowledge, they are routinely used prior to invasive procedures, and attempts are made to correct these abnormalities before invasive procedures. These practices are not supported by the evidence and are harmful to the patients. METHODS This prospective study included 150 patients of cirrhosis undergoing invasive procedures. CCTs [bleeding time (BT), clotting time (CT), international normalized ratio (INR), activated partial thromboplastin time (aPTT) and platelet count], thromboplastin generation time (TGT) and thromboelastography (TEG) were done in all patients, and they were observed for post procedural bleeding. None of the patients received prophylactic transfusion before the procedure. RESULTS BT, CT and TGT were normal in all 150 patients. One of 150 patients developed clinically significant post procedural bleeding. No statistically significant association was seen among INR, aPTT, platelet count and Child class with bleeding. TEG values (R time and MA value) were normal in 61% and 75% patients respectively in spite of abnormal CCTs in most of them. Comparison of abnormal TEG values (R time and MA value) with INR and platelet count, respectively, in patients with no bleeding showed a statistically significant lower percentage of abnormal values of R time and MA value compared to INR and platelet count. CONCLUSION Abnormal CCTs in patients of cirrhosis do not predict bleeding risk. TEG may be useful in patients undergoing invasive procedures to assess bleeding risk and prevents erroneous prophylactic transfusions.

Abstract
PURPOSE OF REVIEW Previous perceptions of cirrhosis as a hypocoagulable state have resulted in empirical blood product transfusions prior to invasive procedures. We evaluate procedure-related bleeding risks in patients with cirrhosis, assess the utility of conventional and newer global coagulation tests, and explore evidence surrounding prophylactic transfusion strategies. RECENT FINDINGS Recent literature supports the concept of a rebalanced, albeit fragile, haemostasis equilibrium in cirrhosis, with a potential hypercoagulable tendency in stable patients. Standard coagulation tests provide a poor reflection of bleeding risks and yet are relied upon for transfusion thresholds. Consequently, a sizeable proportion of patients receive unnecessary blood products. The role of viscoelastic tests to guide transfusions requires further evaluation. In stable cirrhotic patients, procedure-related bleeding rates appear low. Prophylactic transfusion strategies based on arbitrary thresholds lack evidence of clinical benefit. There is a pressing need for point-of-care coagulation tests that represent the complex coagulopathy of cirrhosis and well-powered randomised controlled trials to develop evidence-based pre-procedure transfusion guidelines.

Abstract
Thrombocytopenia is a common haematological disorder in patients with chronic liver disease. It is multifactorial and severity of liver disease is the most influential factor. As a result of the increased risk of bleeding, thrombocytopenia may impact upon medical procedures, such as surgery or liver biopsy. The pathophysiology of thrombocytopenia in chronic liver disease has long been associated with the hypothesis of hypersplenism, where portal hypertension causes pooling and sequestration of all corpuscular elements of the blood, predominantly thrombocytes, in the enlarged and congested spleen. Other mechanisms of importance include bone marrow suppression by toxic substances, such as alcohol or viral infection, and immunological removal of platelets from the circulation. However, insufficient platelet recovery after relief of portal hypertension by shunt procedures or minor and transient recovery after splenic artery embolization have caused many to question the importance and relative contribution of this mechanism to thrombocytopenia. The discovery of the cytokine thrombopoietin has led to the elucidation of a central mechanism. Thrombopoietin is predominantly produced by the liver and is reduced when liver cell mass is severely damaged. This leads to reduced thrombopoiesis in the bone marrow and consequently to thrombocytopenia in the peripheral blood of patients with advanced-stage liver disease. Restoration of adequate thrombopoietin production post-liver transplantation leads to prompt restoration of platelet production. A number of new treatments that substitute thrombopoietin activity are available or in development.

Abstract
The hemostatic environment in patients with cirrhosis is a delicate balance between prohemostatic and antihemostatic factors. There is a lack of effective laboratory measures of the hemostatic system in patients with cirrhosis. Many are predisposed to pulmonary embolus, deep vein thrombosis, and portal vein thrombosis in the pretransplantation setting. This pretransplantation hypercoagulable milieu seems to extend for at least several months post-transplantation. Patients with nonalcoholic fatty liver disease, inherited thrombophilia, portal hypertension in the absence of cirrhosis, and hepatocellular carcinoma often require individualized approach to anticoagulation. Early reports suggest a potential role for low-molecular-weight heparins and direct-acting anticoagulants.

Abstract
BACKGROUND Chronic subdural hematoma (cSDH) is a common neurosurgical ailment, particularly in elderly patients. A recent study uncovered an association between liver disease and recurrence in patients with cSDH. Here, we explored that relationship to identify recurrence predictors in at-risk patients. OBJECTIVE We hypothesized that the association between liver disease and recurrence was attributable to coagulopathy secondary to liver disease. METHODS We retrospectively reviewed all patients with cSDH treated with burr-hole drainage by 2 surgeons between 2007 and 2015. Comorbidities and laboratory findings for each patient were examined by Pearson χ2 analysis or Mann-Whitney U tests. RESULTS We identified 261 cSDH in 215 patients. Patients were a mean age of 65.6 years, and 72% were male. Sixteen patients with cSDH required repeat surgery (6.1%). There were 123 coagulopathic patients (47.1%), and 14 with liver disease (5.4%), all of whom were coagulopathic (P < 0.001). Coagulopathic patients with liver disease were more likely to experience recurrence than patients with coagulopathy alone (relative risk = 4.09, P = 0.019). Patients with liver disease had significantly elevated prothrombin time (P = 0.013) and reduced platelet counts (P < 0.001). Platelets also were reduced in coagulopathic patients with liver disease, as compared with those with coagulopathy alone (P = 0.002). Thrombocytopenia remained significant in a multivariate analysis (P < 0.001). CONCLUSIONS Liver disease is significantly associated with the recurrence of cSDH. Although coagulopathy alone does not predict recurrence, patients with coagulopathy and liver disease are at greater risk for recurrence than those with coagulopathy alone. Liver disease effects are reflected in certain hematologic laboratory values.

Abstract
BACKGROUND The coagulation status of dogs with liver disease is difficult to predict using conventional coagulation testing. HYPOTHESIS/OBJECTIVES To evaluate thromboelastography (TEG) results and associations with conventional coagulation results and indicators of disease severity and prognosis in dogs with chronic hepatopathies (CH). ANIMALS Twenty-one client-owned dogs. METHODS Dogs with CH were prospectively (10 dogs) and retrospectively (11 dogs) enrolled from 2008 to 2014. Kaolin-activated TEG was performed and compared with reference intervals by t-tests or Mann-Whitney tests. Correlation coefficients for TEG results and conventional coagulation and clinicopathologic results were determined. Significance was set at P < .05. RESULTS Dogs with CH had significant increases in R (5.30 min vs 4.33 min), K (3.77 min vs 2.11 min), and LY30 (4.77% vs 0.68%) and decreased angles (55.3° vs 62.4°). G value defined 9 of 21, 7 of 21, and 5 of 21 dogs as normocoagulable, hypercoagulable, and hypocoagulable, respectively. G and MA were correlated with fibrinogen (r = 0.68, 0.83), prothrombin time (PT; r = -0.51, -0.53), and activated partial thromboplastin time (aPTT; r = -0.50, -0.50). K was correlated with PT (r = 0.75) and protein C activity (r = -0.92). Angle was correlated with aPTT (r = -0.63). Clinical score was correlated with PT (r = 0.60), MA (r = -0.53), and R (r = -0.47). Dogs with hyperfibrinolysis (LY30 > 3.04%; 5 of 21) had significantly higher serum transaminase activities. Dogs with portal hypertension had significantly lower G, MA, and angle and prolonged, K, R, and PT. CONCLUSIONS AND CLINICAL RELEVANCE Dogs with CH have variable TEG results. Negative prognostic indicators in CH correlate with hypocoagulable parameters on TEG. Hyperfibrinolysis in dogs with CH is associated with high disease activity.

Abstract
Patients with cirrhosis used to be associated with frequent use of blood components because of their complex disorder of hemostasis and bleeding complications. Recent findings have indicated that patients with cirrhosis have a state of "rebalanced" or even procoagulant hemostasis and have questioned the prophylactic use of plasma. To evaluate the current status of plasma use in patients with cirrhosis, we conducted a retrospective survey in 11 tertiary-care hospitals in China from September 1 to October 31, 2013. All patients admitted with cirrhosis during the study period were included in the study. The survey collected information including patients' diagnostic and demographic data, clinical course including bleeding complications and invasive procedures, laboratory results, and plasma transfusion data. Among 1595 patients with cirrhosis admitted to the 11 hospitals, 236 (14.8%) patients received 1 or more plasma transfusions during the study period. The number of plasma transfusions is defined as the number of transfusion orders. A total of 1037 plasma transfusions were administered to these patients, with a mean of 4.4 transfusions per transfused patient, ranging from 1 to 22 transfusions per transfused patient. Most plasma transfusions (760/1037; 73.3%) were given to patients without bleeding, for treatment of coagulopathy either without planned invasive procedures (70.4%) or before invasive procedures (2.9%). The median dose of plasma transfusion was 3.8 mL/kg. The rate of plasma transfusion of participating hospitals varied from 5.3% to 31.8%. It is encouraging to see that in one teaching hospital, 85.7% plasma transfusions were given to patients with bleeding indication, showing a promising sign in appropriate transfusion. Prophylaxis or empirical plasma transfusion is still a common problem in managing patients with liver cirrhosis. Wide variations are found in plasma transfusion practice among hospitals. Effective measures to control and reduce empirical correction of abnormal coagulation tests through transfusing plasma should be strengthened urgently.

Abstract
BACKGROUND The insertion of central venous catheters (CVCs) may be associated with peri- and post-procedural bleeding. People who require a central line often have disorders of coagulation as a result of their underlying illness, co-morbidities or the effects of treatment. Clinical practice in some institutions is to mitigate the risk of bleeding in these patients by prophylactically transfusing fresh frozen plasma (FFP) in order to correct clotting factor deficiencies prior to central line insertion. However, FFP transfusion is not without risk, and it remains unclear whether this intervention is associated with reduced rates of bleeding or other clinically-meaningful outcomes. OBJECTIVES To assess the effect of different prophylactic plasma transfusion regimens prior to central line insertion in people with abnormal coagulation. SEARCH METHODS We searched for randomised controlled trials (RCTs) in the Cochrane Central Register of Controlled Trials (CENTRAL) (the Cochrane Library 2016, Issue 3), PubMed (e-publications only), Ovid MEDLINE (from 1946), Ovid Embase (from 1974), the Transfusion Evidence Library (from 1950) and ongoing trial databases to 1 March 2016. SELECTION CRITERIA We included RCTs involving transfusions of plasma to prevent bleeding in people of any age with abnormal coagulation requiring insertion of a central venous catheter, published in English. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by Cochrane. MAIN RESULTS We identified four trials eligible for inclusion, of which three are ongoing. We did not exclude any studies because they were not published in English.The included study randomised 81 adults in intensive care whose INR (International Normalised Ratio) was greater than or equal to 1.5 to no FFP or to a single dose of 12 mL/kg FFP prior to undergoing central venous catheterisation (58 participants) or other invasive procedure (23 participants). It is the subgroup of 58 adults undergoing CVC insertion that were included in this review, the study authors provided unpublished data for this review's outcomes.The quality of the evidence was low or very low across different outcomes according to the GRADE methodology. The included study was at high risk of bias due to lack of blinding of participants and personnel and imbalance in the number of participants who had liver disease between study arms.There was insufficient evidence to determine a difference in major procedure-related bleeding within 24 hours (one RCT; 58 participants; no events in either study arm, very low-quality evidence). We are very uncertain whether FFP reduces minor procedure-related bleeding within 24 hours of the study (one RCT; 58 participants, RR 0.67, 95% CI 0.12 to 3.70, very low-quality evidence).No studies were found that looked at: all-cause mortality; the proportion of participants receiving plasma or red cell transfusions; serious adverse reactions (transfusion or line-related complications); number of days in hospital; change in INR; or quality of life.The three ongoing studies are still recruiting participants (expected recruitment: up to 355 participants in total). and are due to be completed by February 2018. AUTHORS' CONCLUSIONS There is only very limited evidence from one RCT to inform the decision whether or not to administer prophylactic plasma prior to central venous catheterisation for people with abnormal coagulation. It is not possible from the current RCT evidence to recommend whether or not prophylactic plasma transfusion is beneficial or harmful in this situation. The three ongoing RCTs will not be able to answer this review's questions, because they are small studies and do not address all of the comparisons included in this review (355 participants in total). To detect an increase in the proportion of participants who had major bleeding from 1 in 100 to 2 in 100 would require a study containing at least 4634 participants (80% power, 5% significance).

Abstract
BACKGROUND Patients with a low platelet count (thrombocytopenia) often require the insertion of central lines (central venous catheters (CVCs)). CVCs have a number of uses; these include: administration of chemotherapy; intensive monitoring and treatment of critically-ill patients; administration of total parenteral nutrition; and long-term intermittent intravenous access for patients requiring repeated treatments. Current practice in many countries is to correct thrombocytopenia with platelet transfusions prior to CVC insertion, in order to mitigate the risk of serious procedure-related bleeding. However, the platelet count threshold recommended prior to CVC insertion varies significantly from country to country. This indicates significant uncertainty among clinicians of the correct management of these patients. The risk of bleeding after a central line insertion appears to be low if an ultrasound-guided technique is used. Patients may therefore be exposed to the risks of a platelet transfusion without any obvious clinical benefit. OBJECTIVES To assess the effects of different platelet transfusion thresholds prior to the insertion of a central line in patients with thrombocytopenia (low platelet count). SEARCH METHODS We searched for randomised controlled trials (RCTs) in CENTRAL (The Cochrane Library 2015, Issue 2), MEDLINE (from 1946), EMBASE (from 1974), the Transfusion Evidence Library (from 1950) and ongoing trial databases to 23 February 2015. SELECTION CRITERIA We included RCTs involving transfusions of platelet concentrates, prepared either from individual units of whole blood or by apheresis, and given to prevent bleeding in patients of any age with thrombocytopenia requiring insertion of a CVC. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by The Cochrane Collaboration. MAIN RESULTS One RCT was identified that compared different platelet transfusion thresholds prior to insertion of a CVC in people with chronic liver disease. This study is still recruiting participants (expected recruitment: up to 165 participants) and is due to be completed in December 2017. There were no completed studies. There were no studies that compared no platelet transfusions to a platelet transfusion threshold. AUTHORS' CONCLUSIONS There is no evidence from RCTs to determine whether platelet transfusions are required prior to central line insertion in patients with thrombocytopenia, and, if a platelet transfusion is required, what is the correct platelet transfusion threshold. Further randomised trials with robust methodology are required to develop the optimal transfusion strategy for such patients. The one ongoing RCT involving people with cirrhosis will not be able to answer this review's questions, because it is a small study that assesses one patient group and does not address all of the comparisons included in this review. To detect an increase in the proportion of participants who had major bleeding from 1 in 100 to 2 in 100 would require a study containing at least 4634 participants (80% power, 5% significance).
