Abstract
BACKGROUND Portal hypertension in cirrhosis brings about a complex interplay in the risks of bleeding and thrombosis. It is unclear whether hospitalized patients with cirrhosis need pharmacological prophylaxis for venous thromboembolism (VTE), as it may increase the risk of bleeding. We aimed to compare the outcome of hospitalized patients with cirrhosis with and without pharmacological thromboprophylaxis. METHODS A comprehensive search of three databases was conducted from inception to August 2022 for studies comparing the outcome of hospitalized patients with cirrhosis with and without pharmacological prophylaxis for VTE. Odds ratios (OR) with 95% confidence intervals (CIs) were calculated for the outcomes of VTE or bleeding. RESULTS Overall, 12 studies were included in the final analysis. The pooled incidence of VTE in patients with and without thromboprophylaxis was 1.9% (95% CI: 0.8-2.9) and 1.9% (95% CI: 0.9-2.9), respectively. The odds of VTE were comparable between the groups with OR 1.11 (95% CI: 0.76-1.62). The pooled incidence of bleeding events in patients with and without thromboprophylaxis was 6.7% (95% CI: 3.6-9.8) and 10.4% (95% CI: 6.6-14.1), respectively. There was no significant difference in the odds of overall bleeding (OR 0.68; 95% CI: 0.30-1.52) or major bleeding (OR 1.18; 95% CI: 0.55-2.56) between the groups. There was no significant difference in the relative effects on sensitivity analysis. CONCLUSION The present analysis could not demonstrate the benefit of pharmacological thromboprophylaxis in reducing in-hospital VTE in patients with cirrhosis. Future studies are required to assess the role of risk prediction models in hospitalized patients with cirrhosis.

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
(1) Background: Severe coronavirus disease can be complicated by a hypercoagulable state in conjunction with sepsis, increasing the risk of venous thromboembolism. This study aimed to observe the effect of anticoagulants on 30-day high-dependency unit (HDU) outcomes of moderate to severe coronavirus disease 2019 (COVID-19) patients of a tertiary care hospital at Rawalpindi, Pakistan. (2) Methods: A retrospective propensity-based case-control study was carried out to examine COVID-19 patients admitted to the HDU. Patient groups who did and did not receive anticoagulants were labeled as "anticoagulant" and "non-anticoagulant", respectively. Case-control matching (1:1) was performed via propensity scores (calculated by a regression model). Kaplan-Meier and logrank analyses were used to study survival probability. Single predictors of outcomes were determined by Cox regression analysis. (3) Results: The anticoagulant group had elevated D-dimers, advanced age, more comorbidities and a higher frequency of severe disease compared to the non-anticoagulant group (p < 0.05). Therefore, 47 cases and 47 matched controls were selected based on their propensity scores. The primary endpoint was outcome (survived vs. died). The 30-day in-HDU mortality was 25.5% for cases and 61.7% for controls (p = 0.0004). The median time from admission to death was 16 days for the case group and 7 days for the control group (p < 0.0001). The 30-day mortality was 19.1% for the enoxaparin group and 16.4% for the heparin group (p > 0.05). Enoxaparin (therapeutic and prophylactic doses) and heparin (prophylactic dose) were found to be independent factors affecting the outcomes of these patients (p < 0.001). (4) Conclusions: Anticoagulants play a beneficial role in reducing mortality among COVID-19 patients. Both anticoagulant formulations, enoxaparin (therapeutic and prophylactic doses) and heparin (prophylactic dose), were associated with improving survival among these patients.

Abstract
Liver cirrhosis is accompanied by complex hemostatic disorders with an increase in the risk of both hemorrhagic and thrombotic complications. Reduced coagulation protein synthesis, such as factors II, VII, IX, X and thrombocytopenia are associated with an increased risk of bleeding. Reducing the synthesis of such anticoagulants as protein C, protein S, antithrombin III is accompanied by increased generation of thrombin, which leads to procoagulant status, increased risk of venous thrombosis, pulmonary embolism, and portal vein thrombosis. Activation of the coagulation cascade increases the risk of thrombosis, and also plays an important role in liver damage, contributing to the progression of fibrosis. Cirrhosis increases the risk of thromboembolic complications of atrial fibrillation.Anticoagulants are necessary for the prevention of thrombosis and thromboembolic complications. However, there are no large prospective studies. There is insufficient data on the safety of anticoagulant therapy in cirrhosis. There are difficulties in monitoring anticoagulation in the application of vitamin K antagonists and low molecular weight heparins.The review presents the available data on the use of warfarin, unfractionated heparin, low molecular weight heparins and direct oral anticoagulants in patients with liver cirrhosis, indicating the need for prevention of venous thrombosis in patients with risk factors, the possibility of preventing decompensation of cirrhosis, reducing the frequency of cardioembolic strokes in patients with atrial fibrillation.

Abstract
BACKGROUND In this study, the authors utilized the IMPROVE (International Medical Prevention Registry on Venous Thromboembolism) bleeding definition to explore the safety profile of pharmacologic venous thromboembolism (VTE) prophylaxis in patients with chronic liver disease (CLD) and concurrent coagulopathy (INR ≥1.5). METHODS A retrospective study was conducted on 193 adult patient admissions with a diagnosis of CLD and INR ≥1.5 not due to therapeutic anticoagulation. Patients were stratified based on their receipt of pharmacological thromboprophylaxis or not during hospitalization. The rates of overall bleeding, defined as the composite of major bleeding and clinically relevant non-major bleeding; major bleeding; and clinically relevant non-major bleeding, within 14 days of admission were evaluated. Secondary endpoints included the rates of thrombosis and mortality. RESULTS The composite of overall bleeding occurred in 17.6% of the admissions. More patients in the group not receiving pharmacological thromboprophylaxis had overall bleeding (18.5% vs 10%), major bleeding (13.3% vs 10%), and clinically relevant non-major bleeding (14.5% vs 5%), with overlapping 95% CI. When stratified per pharmacological thromboprophylaxis status, IMPROVE bleeding risk score (BRS) ≥ 7 was associated with higher rates of overall bleeding, major bleeding, and clinically relevant non-major bleeding as compared to IMPROVE BRS <7, whether patients received or did not receive pharmacological thromboprophylaxis. The overall incidence of in-hospital mortality among our study population was 15.5%. Receiving pharmacological thromboprophylaxis was markedly associated with higher in-hospital mortality (OR = 16.58, 95% CI = 4.47-61.45). CONCLUSION This study shows that the IMPROVE BRS calculated on admission may serve as a guide for omission of thromboprophylaxis in advanced CLD.

Abstract
It is common knowledge that cancer patients are more prone to develop venous thromboembolic complications (VTE). It is therefore not surprising that patients with hepatocellular carcinoma (HCC) present with a significant risk of VTE, with the portal vein being the most frequent site (PVT). However, patients with HCC are peculiar as both cancer and liver cirrhosis are conditions that can perturb the hemostatic balance towards a prothrombotic state. Because HCC-related hypercoagulability is not clarified at all, the aim of the present review is to summarize the currently available knowledge on epidemiology and pathogenesis of non-malignant thrombotic complications in patients with liver cirrhosis and HCC. They are at increased risk to develop both PVT and non-splanchnic VTE, indicating that both local and systemic factors can foster the development of site-specific thrombosis. Recent studies have suggested multiple and often interrelated mechanisms through which HCC can tip the hemostatic balance of liver cirrhosis towards hypercoagulability. Described mechanisms include increased fibrinogen concentration/polymerization, thrombocytosis, and release of tissue factor-expressing extracellular vesicles. Currently, there are no specific guidelines on the use of thromboprophylaxis in this unique population. There is the urgent need of prospective studies assessing which patients have the highest prothrombotic profile and would therefore benefit from early thromboprophylaxis.

Abstract
BACKGROUND AND OBJECTIVES Enoxaparin inactivates factor Xa via a complex formed after binding to circulating anti-thrombin III. This mechanism is reported not to alter hemostatic measures such as clotting time, PT, or PTT. To date, no clinical trials have shown a causal relationship between the clinical/pharmacological effects of enoxaparin on international normalized ratio (INR). The aim of our study is to show the clinical effect of enoxaparin on INR. METHODS Patients (N = 350) were reviewed from our prospective IRB approved databases undergoing gastroesophageal or hepatobiliary surgeries. INR levels were recorded for 6 days: pre-operative to 5 days after surgery. RESULTS Patients (N = 289) received enoxaparin daily starting post-operative day 1, while 61 patients who did not receive enoxaparin were used as controls. The mean post-operative INR in both the 30 and 40 mg groups were both significantly higher than the mean post-operative INR of the control group (P = 0.015 and P = 0.00075, respectively); however postoperative hemoglobin levels were not significantly lower in the enoxaparin versus control. CONCLUSION This is the first clinical evidence of the effect of enoxaparin on INR in patients undergoing abdominal surgeries for malignancies. We demonstrate an increase in the INR for patients who received enoxaparin for post-operative VTE prophylaxis.

Abstract
In this Grand Round presentation, the case of a man with decompensated liver disease is described. He subsequently developed a fatal pulmonary embolism, which may not have occurred if he had been prescribed prophylactic anticoagulation to prevent venous thromboembolic disease. The burden of thrombotic disease in those with chronic liver disease is discussed, before a more detailed analysis of the current evidence, safety data, and clinical dilemmas regarding the use of anticoagulation in patients with chronic liver disease. Finally, the future directions within this field are explored.

Abstract
OBJECTIVES Liver disease (LD) often results in coagulation abnormalities that may predispose to more severe epistaxis. The purpose of this analysis was to examine characteristics of patients hospitalized for epistaxis with LD and explore the impact of LD on patient outcomes. METHODS The 2002 to 2013 National Inpatient Sample was queried for cases with a primary diagnosis of epistaxis. Cases with additional codes meeting the Agency for Healthcare Research and Quality's definition of LD were identified and compared to the non-LD cohort. RESULTS Out of 39,879 cases meeting inclusion criteria, 3.6% had LD. LD was associated with younger age (55.7 years vs. 67.5 years; P < 0.001), longer hospital stay (3.9 days vs. 3.2 days; P < 0.001), and greater hospital charges ($26,141 vs. $18,200; P < 0.001) compared to the non-LD cohort. LD patients had higher rates of alcohol abuse, coagulopathy, chronic blood loss anemia, and renal failure. LD patients also had higher rates of sepsis, urinary/renal complications, respiratory failure, and infectious pneumonia. LD was associated with decreased rates of aggressive management (defined as ligation or embolization) (6.6%-9.0%; P < 0.002) and anterior or posterior nasal packing. In our multivariate logistic regression model correcting for age, gender, race, and significant comorbidities, LD was associated with 1.520 (1.336-1.729; P < 0.001) greater odds of transfusion and 2.264 (1.372-3.736; P = 0.001) greater odds of in-hospital mortality. CONCLUSION Among patients hospitalized for epistaxis, LD resulted in greater morbidity and mortality. Clinicians should be aware of the particular risk that LD bears on the hospitalized epistaxis patient. LEVEL OF EVIDENCE 2C. Laryngoscope, 127:2691-2697, 2017.

Abstract
The presence of cirrhosis poses an increased risk of both thrombosis and bleeding in individuals with chronic liver disease. This duality is a result of a dynamic disequilibrium between procoagulant and anticoagulant states in individuals with cirrhosis. The mechanism of this imbalance in cirrhosis remains unclear. It is known that the progression of cirrhosis leads to decreased synthetic function and a concurrent lack of natural anticoagulants. Other proposed mechanisms contributing to this hemostatic imbalance include decreased platelet production, increased platelet destruction from hypersplenism, decreased synthesis of Vitamin K-dependent and independent clotting factors and anticoagulant factors, and alterations in purinergic signaling pathways. Given the current state of flux in our understanding of bleeding and thrombophilia in cirrhosis, the recommendations for treatment of these conditions are still evolving. We provide a current update on the proposed pathophysiology of altered hemostasis and thrombophilia in cirrhosis. We discuss recent studies in portal vein thrombosis (PVT) and venous thromboembolism (VTE), which are the common thrombotic consequences of cirrhosis, resulting in substantive morbidity and mortality. To address these, we discuss new prophylactic interventions and current treatment options to manage the heightened risk of thrombosis in cirrhosis, while limiting hemorrhagic complications.

Abstract
PURPOSE Coagulopathy resulting from chronic liver disease (CLD) creates uncertainty regarding the risks and efficacy of pharmacologic venous thromboembolism (VTE) prophylaxis (ppx). We aim to describe patient characteristics associated with VTE ppx and the clinical impact of ppx in hospitalized patients with CLD. METHODS This retrospective study included patients with CLD, an international normalized ratio (INR) of ≥1.3, and hospital stay of ≥72 hours. Baseline characteristics, incidence of VTE, and major bleeding were compared between patients given ppx and those not given ppx. RESULTS Of 300 patients with CLD included, 157 (52%) received VTE ppx. Characteristics associated with VTE ppx were lower activated partial thromboplastin time, INR, bilirubin, and Model for End-Stage Liver Disease (MELD) score as well as a higher Padua Prediction Score, hemoglobin, platelet count, and antiplatelet use. VTE occurred in 12 (7.6%) ppx versus 4 (2.8%) non-ppx patients ( P = .07). Major bleeding occurred in 47 (30%) ppx versus 49 (34.3%) non-ppx patients ( P = .46). Ppx was not associated with VTE or bleeding outcomes by multivariate regression. CONCLUSION The use of VTE ppx in hospitalized patients with CLD was not associated with a lower risk of VTE nor did it increase the risk of bleeding. Further studies examining the risks and benefits of VTE ppx in this population are needed.

Prevalence and factors associated with the absence of pharmacologic venous thromboembolism prophylaxis: A cross-sectional study of Georgia intensive care units. J Crit Care 2016; 36:49-53. [PMID: 27546747 DOI: 10.1016/j.jcrc.2016.06.013] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2016] [Revised: 05/16/2016] [Accepted: 06/10/2016] [Indexed: 12/31/2022]
Abstract
PURPOSE The need for venous thromboembolism prophylaxis is well accepted in the intensive care unit (ICU) and supported by a variety of guideline recommendations. Several studies have highlighted poor adherence to these recommendations, but it is unknown why this discrepancy exists. The aim of this study is assess the prevalence of pharmacoprophylaxis and characterize the practice of withholding prophylaxis. MATERIALS AND METHODS Multicenter, cross-sectional study conducted in adults admitted to a Georgia ICU at participating institutions on March 12, 2014. Data were collected on eligible patients regarding need for and omission of pharmacoprophylaxis. RESULTS Three hundred sixty-four patients across 9 institutions were included in the study. Patients had a mean age of 58 years and a median Sequential Organ Failure Assessment score of 5. Physical activity was completely bedridden or restricted in 87% of the cohort. Forty-five percent of patients were not receiving pharmacoprophylaxis. The most common reasons for withholding prophylaxis were receipt of mechanical prophylaxis, recent surgery or central nervous system bleed, and thrombocytopenia. Over 16% of the cohort was inappropriately not receiving thromboprophylaxis. Patients with an elevated international normalized ratio had lower odds of receiving prophylaxis (0.2). CONCLUSIONS Venous thromboembolism prophylaxis is commonly omitted in ICU patients, and reasons for omission vary. An elevated international normalized ratio is associated with withholding of pharmacologic prophylaxis.

Abstract
OBJECTIVE To review current literature for anticoagulation in patients with cirrhosis and provide a summary of the effects of cirrhosis on the coagulation cascade, therapeutic monitoring through interpretation of antifactor Xa (anti-Xa), activated partial thromboplastin time (aPTT), and international normalized ratio (INR) as well as current prophylaxis and treatment recommendations in cirrhotic patients. METHODS A systematic electronic literature search was conducted in PubMed using the key termsanticoagulation, warfarin, low-molecular-weight heparin(LMWH),unfractionated heparin(UFH),target-specific oral anticoagulants, deep-vein thrombosis(DVT),pulmonary embolism(PE),portal vein thrombosis(PVT),venous thromboembolism, anti-Xa, activated partial thromboplastin time, anticoagulation therapeutic monitoring, coagulopathy, coagulation cascade, chronic liver disease, cirrhosis, anddecompensated liver disease STUDY SELECTION Studies written in the English language from January 2000 to December 2015 were considered for this review article. All search results were reviewed, and the relevance of each article was determined by authors independently. CONCLUSIONS Patients with cirrhosis are at higher risk for both bleeding and thrombosis-related complications. Cirrhosis affects production of both procoagulant and anticoagulant factors, thus resulting in increased INR and aPTT levels and decreased anti-Xa levels. LMWH is the treatment of choice for the prevention and treatment of DVT/PE/PVT in patients with cirrhosis, and monitoring with anti-Xa levels for dose adjustment is not recommended. UFH is an alternative in cirrhotic patients for shorter-term use and in cases of severe renal dysfunction and/or hemodynamic instability. Cirrhotic patients on anticoagulation therapy should be monitored closely for signs and symptoms of bleeding and thrombosis.

Abstract
Patients with cancer are at increased risk of venous thromboembolism (vte). Anticoagulation therapy is used to treat vte; however, patients with cancer have unique clinical circumstances that can often make decisions surrounding the administration of therapeutic anticoagulation complicated. No national Canadian guidelines on the management of established cancer-associated thrombosis have been published. We therefore aimed to develop a consensus-based, evidence-informed guideline on the topic. PubMed was searched for clinical trials and meta-analyses published between 2002 and 2013. Reference lists of key articles were hand-searched for additional publications. Content experts from across Canada were assembled to review the evidence and make recommendations. Low molecular weight heparin is the treatment of choice for cancer patients with established vte. Direct oral anticoagulants are not recommended for the treatment of vte at this time. Specific clinical scenarios, including the presence of an indwelling venous catheter, renal insufficiency, and thrombocytopenia, warrant modifications in the therapeutic administration of anticoagulation therapy. Patients with recurrent vte should receive extended (>3 months) anticoagulant therapy. Incidental vte should generally be treated in the same manner as symptomatic vte. There is no evidence to support the monitoring of anti-factor Xa levels in clinically stable cancer patients receiving prophylactic anticoagulation; however, levels of anti-factor Xa could be checked at baseline and periodically thereafter in patients with renal insufficiency. Follow-up and education about the signs and symptoms of vte are important components of ongoing patient care.
