The effect of pharmacist-led interventions on the appropriateness and clinical outcomes of anticoagulant therapy: a systematic review and meta-analysis.

AIM: Although pharmacist-led interventions in anticoagulant (AC) therapy are widely accepted, there is a lack of evidence comparing their effectiveness to usual care in terms of AC therapy appropriateness and clinical outcomes. We aimed to estimate the comparative effectiveness of pharmacist-led interventions on the appropriateness and clinical outcomes of AC therapy. METHODS AND RESULTS: Adhering to the PRISMA guidelines, we searched PubMed, EMBASE, and Scopus databases to identify randomised controlled trials and quasi-experimental and cohort studies published between 2010 and 2023. A random-effects model was used to calculate pooled intervention effects. We assessed heterogeneity (using Higgins' I2 and Cochran's Q) and publication bias (using Egger's test, the trim-and-fill method and visualisation of the funnel plot). In total, 35 studies involving 10 374 patients in the intervention groups and 11 840 in the control groups were included. The pharmacist-led interventions significantly improved the appropriateness of AC therapy (odds ratio [OR]: 3.43; 95% confidence interval [CI]: 2.33-5.06, p < 0.01). They significantly decreased total bleeding (relative risk [RR]: 0.75, 95% CI: 0.58-0.96, p = 0.03) and hospitalisation or readmission (RR: 0.64, 95% CI: 0.41-0.99, P = 0.04). However, the impact of the pharmacist-led interventions on thromboembolic events (RR: 0.69, 95% CI: 0.46-1.02, p = 0.07) and mortality (RR: 0.76, 95% CI: 0.51-1.13, p = 0.17) were not significant. CONCLUSION: Pharmacist-led interventions demonstrated superior outcomes in optimising AC therapy compared to usual care. Further research is needed to evaluate pharmacist-led interventions' cost-effectiveness and long-term sustainability.PROSPERO registration number CRD42023487362.

Real world risk of discontinuing oral anticoagulation after successful catheter ablation for atrial fibrillation.

Background: Many patients with atrial fibrillation (AF) discontinued oral anticoagulation (OAC) therapy after successful catheter ablation. We aimed to determine the real-world risks and consequences of discontinuing OAC use after catheter ablation for AF. Methods: Patients who underwent successful catheter ablation for AF from January 2004 to December 2020 were divided into continued long-term OAC (On-OAC, n = 1062) and discontinued (Off-OAC, n = 1055) groups. The long-term outcomes including thromboembolic events, major bleeding, all-cause mortality and major adverse cardiovascular events (MACE), were compared between the two groups. Results: The CHA2DS2-VASc score was 3.44 ± 1.12. After a mean follow-up of 37.09 months, thromboembolism risk was higher and major bleeding risk was lower in the Off-OAC than in the On-OAC group (Both log-rank P < 0.001). CHA2DS2-VASc score-stratified subgroup analysis showed similar cumulative event rates between the two groups in men and women with scores of 2 and 3 (intermediate risk for stroke), respectively, (P > 0.05), except for a higher major bleeding rate in the On-OAC group (P = 0.002). Patients at high risk for stroke (men and women with scores ≥3 and ≥ 4) had better non-thromboembolic and non-MACE results (Both log-rank P < 0.05). Conclusion: Men with a CHA2DS2-VASc score of 2 and women with a score of 3 had a relatively low incidence of stroke events after successful catheter ablation for AF and may be safe for anticoagulation cessation. Greater benefits from long-term OAC were observed in men with CHA2DS2-VASc score ≥3 and women with score ≥4.

Paravertebral Block for Multiple Rib Fractures in an Anticoagulated Trauma Patient.

This case report presents the complex analgesia management of a 52-year-old male with a significant medical history including atrial fibrillation treated with apixaban, essential trigeminal neuralgia, non-ischemic cardiomyopathy, and chronic systolic heart failure. The patient experienced a loss of control while riding a motorized bicycle, resulting in a fall and head injury with no loss of consciousness. Upon admission, he tested positive for ethanol, cannabinoids, and oxycodone. The physical exam was significant for right cephalohematoma and right elbow hematoma. Imaging revealed multiple injuries, including right rib fractures (T3-12) with hemothorax. Right paravertebral catheters were placed in the intensive care unit (ICU).

Chronic Expanding Hematoma in the Upper Extremity: A Case Report on Diagnostic and Management Challenges.

Hematomas are a common occurrence in clinical practice, often resulting from trauma or underlying bleeding disorders. They can manifest with various symptoms depending on their location and size. While hematomas are typically straightforward to diagnose and manage, specific presentations can pose diagnostic challenges. We present the case of a growing post-traumatic right upper extremity mass in a 67-year-old male on anticoagulant medication, Xarelto (rivaroxaban) 20mg, with no history of bleeding disorders. Differential diagnoses include a benign lipoma or possible soft-tissue malignancy. The mass was surgically excised and sent to pathology, which confirmed it was a hematoma and led to a diagnosis of a chronic expanding hematoma. Ultrasonography, computed tomography, and magnetic resonance imaging are diagnostic modalities that can help distinguish different presentations. Despite the commonality of hematomas in clinical practice, atypical hematomas may also present unique challenges in diagnosis and management due to their varied clinical presentations and locations. This report underlines the importance of understanding hematomas' diverse etiologies, presentations, and imaging characteristics for appropriate treatment and diagnosis.

Thromboembolism after coronavirus disease 2019 vaccination in atrial fibrillation/flutter: a self-controlled case series study.

BACKGROUND AND AIMS: Concerns about the safety of coronavirus disease 2019 (COVID-19) vaccines in patients with atrial fibrillation/flutter (AF/AFL) have arisen due to reports of thrombo-embolic events following COVID-19 vaccination in the general population. This study aimed to evaluate the risk of thrombo-embolic events after COVID-19 vaccination in patients with AF/AFL. METHODS: This was a modified self-controlled case-series study using a comprehensive nationwide-linked database provided by the National Health Insurance Service in South Korea to calculate incidence rate ratios (IRRs) of thrombo-embolic events. The study population included individuals aged ≥12 years who were either vaccinated (e.g. one or two doses) or unvaccinated during the period from February to December 2021. The primary outcome was a composite of thrombo-embolic events, including ischaemic stroke, transient ischaemic attack, and systemic thromboembolism. The risk period was defined as 0-21 days following COVID-19 vaccination. RESULTS: The final analysis included 124 127 individuals with AF/AFL. The IRR of thrombo-embolic events within 21 days after COVID-19 vaccination, compared with that during the unexposed control period, was 0.93 [95% confidence interval (CI) 0.77-1.12]. No significant risk variations were noted by sex, age, or vaccine type. However, patients without anticoagulant therapy had an IRR of 1.88 (95% CI 1.39-2.54) following vaccination. CONCLUSIONS: In patients with AF/AFL, COVID-19 vaccination was generally not associated with an increased risk of thrombo-embolic events. However, careful individual risk assessment is required when advising vaccination for those not on oral anticoagulant, as these patients exhibited an increased risk of thrombo-embolic events post-vaccination.

Effectiveness of Direct Oral Anticoagulants and Vitamin K Antagonists in Preventing Stroke in Patients With Atrial Fibrillation and Liver Cirrhosis: A Systematic Review and Meta-Analysis.

Patients with atrial fibrillation and concurrent liver cirrhosis have been excluded from major clinical trials evaluating direct oral anticoagulants (DOACs) due to safety concerns. This has led to uncertainty regarding the optimal anticoagulant therapy in this population at high risk of thromboembolic events. We conducted a systematic review and meta-analysis to compare the effectiveness and safety of DOACs versus vitamin K antagonists (VKAs) in patients with atrial fibrillation and liver cirrhosis. Databases including Embase, MEDLINE/PubMed, and Web of Science were searched for relevant studies. The primary effectiveness outcome was stroke or systemic embolism, and the safety outcome was major bleeding events. A total of 10 studies were included in the meta-analysis. Compared to VKAs, the use of DOACs was associated with a significantly lower risk of stroke or systemic embolism (RR: 0.78, 95% CI: 0.65-0.92, p=0.005). The risk of all-cause mortality was comparable between the two groups (RR: 0.89, 95% CI: 0.74-1.07, p=0.23). Notably, DOACs demonstrated a significantly lower risk of major bleeding events (RR: 0.67, 95% CI: 0.61-0.73, p<0.01) compared to VKAs. This meta-analysis suggests that DOACs may be a favorable alternative to VKAs for the prevention of thromboembolic events in patients with atrial fibrillation and liver cirrhosis, with a lower risk of stroke or systemic embolism and major bleeding. However, further research is needed to establish optimal dosing strategies and assess the safety and efficacy of DOACs in patients with advanced liver disease.

Antithrombotic therapy at discharge and prognosis in patients with chronic coronary syndrome and atrial fibrillation who underwent PCI: a real-world study.

BACKGROUND: This study aimed to describe the status of antithrombotic therapy at discharge and prognosis in patients with atrial fibrillation (AF) and chronic coronary syndrome (CCS) who underwent percutaneous coronary intervention (PCI). METHODS: This was an observational, prospective study. The primary endpoint was major adverse cardiovascular events (MACE), including all-cause death, myocardial infarction, stroke/transient ischemic attach (TIA), systemic embolism or ischemia-driven revascularization. Bleeding events were collected according to the Thrombolysis in Myocardial Infarction (TIMI) criteria. RESULTS: Between 2017 and 2019, a cohort of 516 patients (mean age 66, [SD 9], of whom 18.4% were female) with AF and CCS who underwent PCI were evaluated, with a median followed-up time of 36 months (Interquartile range: 22-45). MACE events occurred in 13.0% of the patients, while the TIMI bleeding events were observed in 17.4%. Utilization of TAT (triple antithrombotic therapy) (P < 0.001) and oral anticoagulation (OAC) therapy (P < 0.001) increased through years. History of heart failure (HF) (Hazard ratio [HR], 1.744; 95% confidence interval [CI], 1.011-3.038) and TAT (HR, 2.708; 95%CI, 1.653-4.436) had independent associations with MACE events. OAC (HR, 10.378; 95%CI, 6.136-17.555) was identified as a risk factor for bleeding events. A higher creatine clearance (HR, 0.986; 95%CI, 0.974-0.997) was associated with a lower incidence of bleeding events. CONCLUSIONS: Antithrombotic therapy has been improved among patients with AF and CCS who underwent PCI these years. History of HF and TAT were independently associated with MACE events. Higher creatine clearance was protective factor of bleeding events, while OAC was a risk factor for TIMI bleeding events.

Hemorrhagic Cholecystitis in a Patient Under Anticoagulant and Antiplatelet Therapy: A Case Report.

Hemorrhagic cholecystitis is an uncommon presentation of acute cholecystitis. Due to its etiology and unspecific clinical data, it is an entity that represents a diagnostic challenge. We present a case of a 70-year-old male with diabetes type 2, hypertension, and chronic kidney disease with hemodialysis, who attended the emergency department with sudden-onset abdominal pain in the epigastrium. The patient presented no additional symptoms, a normal electrocardiogram, but due to the characteristics of the pain and elevated troponin I, emergency medicine specialists considered an acute coronary syndrome and initiated antiplatelet and anticoagulant therapy. Due to persistent abdominal pain, a decrease in hemoglobin, and the onset of arterial hypotension, a computed tomography (CT) scan was performed, which revealed perforation of the gallbladder, apparent hemorrhagic cholecystitis, and hemoperitoneum. The patient underwent emergent surgery, where CT findings were confirmed. In our case, the suspicion of hemorrhagic cholecystitis arose until the clinical case was advanced, after receiving anticoagulant and antiplatelet therapy, and it was confirmed during surgery and with histopathology. This concludes that hemorrhagic cholecystitis is a rare disease and difficult to diagnose. Therefore, studies should focus on clinical presentation and risk factors (e.g., trauma, malignancy, renal failure, cirrhosis, and anticoagulation therapy) to promote early diagnosis and avoid complications.

Associations of RBC counts and incidence of DVT in patients with spinal cord injury: a five year observational retrospective study.

BACKGROUND: The role of red blood cell (RBC) counts as potential independent risk factors for deep vein thrombosis (DVT) in patients with spinal cord injury (SCI) remains uncertain. This study aims to clarify the associations between RBC counts and DVT incidence among this population. METHODS: A retrospective analysis was performed on 576 patients with SCI admitted to the rehabilitation medicine department from January 1, 2017 to December 31, 2021. After exclusions, 319 patients were analyzed, among which 94 cases of DVT were identified. RESULTS: Mode of injury, D-dimer and anticoagulant therapy were significant covariates (P < 0.05). Age, fibrinogen, D-dimer, anticoagulant therapy and American Spinal Cord Injury Association impairment scale (AIS) grades were associated with RBC counts and DVT incidence (P < 0.05). Adjusting for these factors, a 1.00 × 10^12/L increase in RBC counts correlated with a 45% decrease in DVT incidence (P = 0.042), revealing a "U" shaped relationship with a pivot at 4.56 × 10^12/L (P < 0.05). CONCLUSION: RBC counts below 4.56 × 10^12/L serve as a protective factor against DVT, while counts above this threshold pose a risk. These findings could inform the development of DVT prevention strategies for patients with SCI, emphasizing the need for targeted monitoring and management of RBC counts.

Intracardiac and Cerebral Thrombosis Complicated With Mycoplasma Pneumonia.

A seven-year-old girl developed multiposition thrombosis after fever and respiratory symptoms. Chest computed tomography (CT) scan demonstrated bilateral infiltrates, consolidation of the right lower lobe, and pleural effusion in the right lung field. Brain magnetic resonance imaging (MRI) showed multiple abnormal signals in the brain with limited diffusion, and cerebral infarction could not be excluded. Echocardiography revealed hypoechoic mitral valve tips, which are likely to be suspected as vegetation. Mycoplasma pneumoniae infection was clarified by a four-fold increase in IgG antibodies to M. pneumoniae sera. D-dimer levels were elevated increasingly. We found and reported this rare pediatric case of an M. pneumoniae-induced severe pneumonia complicated with intracardiac and cerebral thrombosis. We investigate the clinical characteristics, diagnosis, and treatment of refractory mycoplasma pneumonia complicated with intracardiac and cerebral thrombosis in children.

Aspirin-Induced Massive Spontaneous Sublingual Hematoma.

Sublingual hematoma, a rare but potentially life-threatening condition, can arise spontaneously or secondary to various triggers, including trauma, dental procedures, or anticoagulant therapy. We present a case of massive spontaneous sublingual hematoma in a 45-year-old woman receiving aspirin therapy for rheumatic heart disease. Despite the absence of trauma or procedural triggers, the patient presented with bleeding from the floor of the mouth and significant submental swelling, prompting urgent intervention to secure the airway and manage coagulopathy. Conservative measures, including discontinuation of aspirin and intravenous vitamin K administration, led to gradual hematoma resolution and favorable patient outcomes. This case highlights the importance of prompt recognition and early management of sublingual hematoma, particularly in the context of aspirin therapy-induced coagulopathy.

Assessment of lytic therapy effect in patients with intermediate-high risk pulmonary embolism for prevention of chronic thromboembolic pulmonary hypertension: A randomized, double-blind trial.

Background and Aims: This study aims to compare the effectiveness of thrombolytic therapy and anticoagulation in preventing chronic thromboembolic pulmonary hypertension (CTEPH). Method: A total of 60 patients with intermediate-high risk pulmonary embolism (PE) were randomly assigned to receive either thrombolytic therapy (n = 30) or anticoagulation (n = 30). Results: Echocardiographic assessments demonstrated no significant differences between the two treatment approaches in terms of right ventricular size (RVS) (on discharge in thrombolytic group: 31.17 ± 3.43 vs. anticoagulant group: 32.73 ± 5.27, p = 0.912), tricuspid annular plane systolic excursion (TAPSE) (on discharge in thrombolytic group: 17.66 ± 2.39 vs. anticoagulant group: 16.73 ± 2.93, p = 0.290), and systolic pulmonary artery pressure (SPAP) (on discharge in thrombolytic group: 32.93 ± 9.73 vs. anticoagulant group: 34.46 ± 9.30, p = 0.840). However, significant changes were observed in all assessed parameters within each treatment group (p < 0.001). The 6-month follow-up showed no significant difference between the two groups in terms of CTEPH incidence (p = 0.781) or functional class of the patients (p = 0.135). Conclusion: Based on the findings of this study, neither thrombolytic therapy nor anticoagulation demonstrated superiority over the other in reducing adverse outcomes associated with intermediate-high risk PE, including right ventricular size, SPAP, TAPSE, or CTEPH.

Effect of a 3-Month Single-Drug Approach Using Rivaroxaban for Symptomatic Proximal Deep Vein Thrombosis.

Background: Factor Xa inhibitors, such as rivaroxaban, are increasing the convenience of treatment for deep vein thrombosis (DVT). Limited evidence exists regarding clot evaluation at 3 months after treatment for DVT. Methods and Results: We retrospectively analyzed the clinical course of symptomatic proximal DVT in patients who received 3 months of anticoagulation treatment at our hospital. Patients treated with the rivaroxaban single-drug approach were classified as group A (n=42). Patients treated with unfractionated heparin (UFH) or subcutaneous fondaparinux followed by vitamin K antagonist comprised group B (n=60) as an historical cohort. The quantitative ultrasound thrombosis (QUT) score was used to quantify clot burden before and after treatment. No significant differences were observed in patient characteristics between the groups. Serum D-dimer levels in both groups significantly improved after treatment. Clot volume assessed using QUT also reduced significantly in both groups. The QUT score in groups A and B improved from 7.5 [4.8, 12.0] to 3.0 [1.8, 5.0; P=0.000] and 7.0 [4.0, 9.8] to 3.0 [2.0, 5.0; P=0.000], respectively. The change in QUT (∆QUT) was significantly greater in group A compared with group B (-4.5 [-8.25, -2.0] vs. -2.0 [-6.0, 0.0]; P=0.005). Conclusions: We were able to demonstrate the effectiveness of DVT treatment using rivaroxaban over a period of 3 months from onset, in terms of clot regression evaluated using the QUT score.

Management of atrial arrhythmias identified by cardiac devices.

Implantable cardiac devices have shown that atrial fibrillation (AF) is more frequent than previously assumed, with subclinical, asymptomatic, self-limiting manifestations called atrial high-rate events (AHREs) or subclinical AF. The clinical significance and correct therapeutic management of these episodes of subclinical AF is less well defined than in the case of clinically manifest AF. Two important randomized studies on the topic have recently been published, NOAH-AFNET 6 and ARTESIA, which, however, have not definitively clarified the topic. In patients with AHRE or subclinical AF, the average thrombo-embolic risk is lower than that in patients with clinically manifest AF and is ∼1%. For this reason, in these patients, the possibility that the benefit of anticoagulant therapy is overshadowed by the risk of bleeding is very high. Therefore, while waiting for new tools that allow a better stratification of low-risk patients, we must rely on individual clinical evaluation and overcome the qualitative dichotomy (AHRE yes vs. AHRE no), preferring instead an approach that is as quantitative as possible and takes into account the number of episodes, their duration, and the patient's CHADSVASC score, before deciding, in each individual case, whether or not to use anticoagulant therapy.

Cerebral haemorrhage in the patient with atrial fibrillation: do we employ the direct oral anticoagulants without waiting too long?

Intracranial haemorrhage (ICH) is the most feared haemorrhagic complication of oral anticoagulant therapy (OAT), although the risk is significantly lower with direct oral anticoagulants (DOACs) compared with warfarin. Intracranial haemorrhage is generally considered, by clinicians, to be an absolute contraindication to starting or resuming OAT in patients with atrial fibrillation (AF). On the other hand, the pivotal trials with DOACs excluded patients with previous ICH. Observational studies actually indicate a net clinical benefit in favour of DOAC in patients with AF and previous ICH. This benefit is confirmed by randomized clinical trials which, however, have the limitation of the small number of cases, but larger clinical trials comparing DOACs vs. aspirin or no therapy are underway. While OAT is certainly contraindicated in patients with lobar ICH and cerebral amyloid angiopathy, in other cases, the decision must be made in the individual patient through an accurate balance between thromboembolic risk and haemorrhagic risk and a multidisciplinary cardio-neurological evaluation.

Understanding the incidence of atrial fibrillation and stroke in hypertrophic cardiomyopathy patients: insights from Danish nationwide registries.

AIMS: The treatment of atrial fibrillation (AF) in hypertrophic cardiomyopathy (HCM) can be challenging since AF aggravates symptoms and increases the risk of stroke. Which factors contribute to the development of AF and stroke in HCM remains unknown. The aim of this study was to determine the incidence of AF and stroke in HCM patients and identify the risk factors. METHODS AND RESULTS: Using Danish national registries, all HCM patients from 2005 to 2018 were included. The association between HCM, incident AF, and stroke was investigated using multivariable Cox proportional hazards analysis. Cumulative incidences were calculated using the Aalen-Johansen estimator. Among the 3367 patients without prevalent AF, 24% reached the endpoint of incident AF with death as a competing risk. Median follow-up time was 4 years. Atrial fibrillation incidence was equal between sexes and increased for patients with ischaemic heart disease [IHD; hazard ratio (HR) 1.33, 95% confidence interval (CI) 1.08-1.63], hypertension (HT) (HR 1.36, 95% CI 1.14-1.67), and obstructive HCM (HR 1.27, 95% CI 1.05-1.52). Seven per cent developed stroke, with no difference detected stratifying for the presence of AF. Sub-analysis revealed that when AF was treated with oral anticoagulants (OACs), stroke was less likely (HR 0.4, 95% CI 0.18-0.86, P = 0.02). However, 34% of patients were not receiving adequate anticoagulation following AF diagnosis. CONCLUSION: Obstructive HCM, HT, and IHD were associated with increased risk of AF. Prevalent AF alone was not predictive of stroke; however, AF patients treated with OAC were significantly less likely to develop stroke, suggesting that this development is driven by the protective effect of OAC. Despite this, 34% of patients did not receive OAC.

Observational study of frailty in older Japanese patients with non-valvular atrial fibrillation receiving anticoagulation therapy.

The number of patients with atrial fibrillation is increasing, and frailty prevalence increases with age, posing challenges for physicians in prescribing anticoagulants to such patients because of possible harm. The effects of frailty on anticoagulant therapy in older Japanese patients with nonvalvular atrial fibrillation (NVAF) are unclear. Herein, we prescribed rivaroxaban to Japanese patients with NVAF and monitored for a mean of 2.0 years. The primary endpoint was stroke or systemic embolism. The secondary endpoints were all-cause or cardiovascular death, composite endpoint, and major or non-major bleeding. Frailty was assessed using the Japanese long-term care insurance system. A multiple imputation technique was used for missing data. The propensity score (PS) was obtained to estimate the treatment effect of frailty and was used to create two PS-matched groups. Overall, 5717 older patients had NVAF (mean age: 73.9 years), 485 (8.5%) were classified as frail. After PS matching, background characteristics were well-balanced between the groups. Rivaroxaban dosages were 10 and 15 mg/day for approximately 80% and the remaining patients, respectively. Frailty was not associated with the primary endpoint or secondary endpoints. In conclusion, frailty does not affect the effectiveness or safety of rivaroxaban anticoagulant therapy in older Japanese patients with NVAF.Trial registration: UMIN000019135, NCT02633982.

Atrial High-Rate Episodes in Elderly Patients: The Anticoagulation Therapy Dilemma.

Atrial fibrillation (AF) has been associated with higher morbidity and mortality rates, especially in older patients. Subclinical atrial fibrillation (SCAF) is defined as the presence of atrial high-rate episodes (AHREs) > 190 bpm for 10 consecutive beats > 6 min and <24 h, as detected by cardiac implanted electronic devices (CIEDs). The selection of eligible patients for anticoagulation therapy among elderly individuals with AHREs detected through CIEDs remains a contentious issue. The meta-analysis of ARTESiA and NOAH-AFNET 6 clinical trials revealed that taking Edoxaban or Apixaban as oral anticoagulation therapy can reduce the risk of stroke by approximately 32% while increasing the risk of major bleeding by approximately 62%. However, it is still unclear which are, among patients with SCAF, those who can take the highest net clinical benefit from anticoagulant therapy. The present review summarizes the current evidence on this intriguing issue and suggests strategies to try to better stratify the risk of stroke and systemic embolism in patients with AHREs. We propose incorporating some parameters including chronic kidney disease (CKD), obesity, enlarged left atrial volume, the efficacy in blood pressure management, and frailty into the traditional CHA2DS2-VASc score. Future trials will be needed to verify the clinical usefulness of the proposed prognostic score mainly in the view of a personalized therapeutic approach in patients with SCAF.

Safety/efficacy of atezolizumab + bevacizumab during anti-platelet/anticoagulation therapy in unresectable hepatocellular carcinoma.

BACKGROUND AND AIMS: This study aimed to determine the safety and efficacy of atezolizumab + bevacizumab therapy in hepatocellular carcinoma patients receiving anti-platelet agents or anticoagulants. METHODS: Patients were divided into those using (IM out) and those not using (IM in) anti-platelet agents or anticoagulants, who violated the exclusion criteria of the IMbrave150 trial, and were retrospectively examined. RESULTS: The study included 185 patients (IM in: 157; IM out: 28). For first-line treatment, progression-free survival was 184 days for IM in and 266 days for IM out (p = .136). Overall survival was 603 days for IM in and not reached for IM out (p = .265), with no significant between-group difference. Similarly, there were no significant between-group differences in progression-free survival or overall survival for later-line treatment. Haemorrhagic adverse events of ≥grade 3 were observed in 11 IM in patients and 3 IM out patients. No significant factors associated with haemorrhagic adverse events of ≥grade 3 were identified in the multivariate analysis including IM out classification, whose p value was .547. Regarding thrombotic/embolic adverse events in the IM out group, one case of exacerbation of portal vein thrombosis was observed. No deaths were directly attributable to bleeding events or exacerbations of thrombosis. CONCLUSION: Atezolizumab + bevacizumab therapy shows similar safety and efficacy in patients receiving and those not receiving anti-platelet agents or anticoagulants; therefore, it can be considered for patients with hepatocellular carcinoma receiving anti-platelet agents or anticoagulants.

Prevalence, treatment efficacy, and risk factors of vascular complications in acute pancreatitis: A case-control study.

OBJECTIVE: We aimed to investigate the prevalence of vascular complications in acute pancreatitis (AP), to compare patient outcomes using various treatments, and to explore the related risk factors. METHODS: Consecutive AP patients admitted from January 2010 to July 2017 were retrospectively included. Demographics, vascular complications, laboratory indices, and imaging findings were collected. Univariate and multivariate analyses were used to explore potential risk factors of vascular complications. RESULTS: Of 3048 AP patients, 808 (26.5%) had vascular complications, including visceral vein thrombosis, sinistral portal hypertension, and arterial complications. And 38 (4.7%) patients received anticoagulant therapy and had a higher rate of recanalization (P < 0.001). Bleeding occurred in 95 (11.8%) patients, who received further treatment. Multivariate analysis identified male gender (odds ratio [OR] 1.650, 95% confidence interval [CI] 1.101-2.472), hyperlipidemia (OR 1.714, 95% CI 1.356-2.165), disease recurrence (OR 3.727, 95% CI 2.713-5.118), smoking (OR 1.519, 95% CI 1.011-2.283), hemoglobin level (OR 0.987, 95% CI 0.981-0.993), white blood cell (WBC) count (OR 1.094, 95% CI 1.068-1.122), non-vascular local complications (OR 3.018, 95% CI 1.992-4.573), computed tomography severity index (CTSI) (OR 1.425, 95% CI 1.273-1.596), and acute physiology and chronic health evaluation (APACHE) II score (OR 1.057, 95% CI 1.025-1.090) were related to vascular complications. CONCLUSIONS: Vascular complications in AP is prevalent and their treatment is challenging. Further investigations are warranted to determine the optimal treatment strategy. Independent risk factors included male gender, hyperlipidemia, disease recurrence, smoking, WBC count, non-vascular local complications, CTSI, and APACHE II score.
