RESUMO
BACKGROUND: Soluble P-selectin (sP-selectin) has been proposed as a potential biomarker for venous thromboembolism (VTE) diagnosis with interesting results. However, its role in predicting early mortality in pulmonary embolism (PE) remains unexplored. METHODS: This observational, prospective, single-center study enrolled consecutive patients aged 18 or older with confirmed acute symptomatic PE and no prior anticoagulation. The study aims to assess the prognostic capacity of sP-selectin measured at the time of PE diagnosis for short-term mortality and major bleeding. RESULTS: A total of 196 patients, with a mean age of 69.1 years (SD 17), were included, of whom 52.6% were male. Within 30 days, 9.7% of patients (n = 19) died, and 5.1% (n = 10) suffered major bleeding. PE risk stratification revealed 4.6% (n = 9) with high-risk PE, 34.7% (n = 68) with intermediate-high-risk PE, 38.3% (n = 75) with intermediate-low-risk PE, and 22.5% (n = 44) with low-risk PE according to the European Society of Cardiology score. Mean plasma sP-selectin levels were comparable between survivors and non-survivors (489.7 ng/mL ±63 vs. 497.3 ng/mL ±51; p = .9). The ROC curve for 30-day all-cause mortality and major bleeding yielded an AUC of 0.49 (95% CI 0.36-0.63) and 0.46 (95% CI 0.24-0.68), respectively. Multivariate and survival analyses were precluded due to lack of significance. CONCLUSIONS: sP-selectin was not useful for predicting short-term mortality or major bleeding in patients with acute symptomatic pulmonary embolism. Further studies are required to clarify the role of sP-selectin in VTE, particularly in prognosticating PE outcomes.

Behçet syndrome (BS) is a unique type of vasculitis that affects veins and arteries of all sizes, leading to recurrent vascular events, mostly venous thrombosis. The prevalence of venous thromboembolism in BS patients ranges between 15 and 40%. Thrombosis is usually an early manifestation leading to diagnosis of BS in up to 40% of patients. BS is per se a model of inflammation-induced thrombosis. The primary autoimmune response activates lymphocytes that in turn produce a cytokine cascade that activates neutrophils, which modify the secondary structure of fibrinogen making it less susceptible to plasmin-induced lysis. This leads to endothelial dysfunction, platelet activation and overexpression of tissue factor leading to inflammatory thrombi, usually attached to the wall. The pathogenesis of thrombosis is especially relevant to direct the specific treatment, that is based on immunosuppression rather than anticoagulation. Superficial vein thrombosis (SVT) and deep vein thrombosis (DVT) are the most common form of thrombosis in BS, but thrombosis in atypical sites (cava vein, suprahepatic veins, intracardiac thrombus) and arterial involvement can also occur. We assessed the latest update of the European League Against Rheumatism recommendations for the management of BS. Vascular Behçet treatment is usually based of immunosuppressants, and the role of anticoagulation remains controversial. The use of interventional and surgical procedures should be carefully evaluated, due to the risk of triggering a vascular pathergy phenomenon.

OBJECTIVE: The role of hypertension in COVID-19 has not been clearly elucidated yet. The aim of this study was to evaluate the incidence and severity of COVID-19 in a hypertensive population and assess whether there is a link between blood pressure control and SARS-CoV-2 infection outcomes. METHODS: This was a single-center retrospective observational study that evaluated the incidence and severity of COVID-19 in a chronic hypertensive population (n=1,637) from a specialized consultation of Hypertension and Cardiovascular Risk of Internal Medicine in a tertiary hospital in Madrid (Spain). RESULTS: A total of 147 COVID-19 patients (9%) were found, with a median age of 59 (±14) years, where 77 (52.4%) patients were male. Forty patients required hospitalization (27.2%), 15 patients had severe COVID-19 (10.2%), and 6 patients died (4.1%). Among the causes of hypertension, 104 (70.7%) patients had essential hypertension and 22 (15%) patients presented primary hyperaldosteronism; and 66 (44.9%) patients presented RH. Severe COVID-19 was associated with age over 65 years (crude OR 4.43 [95% CI 1.3-14.2; p = .012]) and diabetes mellitus (crude OR 4.15 [95% CI 1.3-12.9; p = .014]). CONCLUSION: This study showed a lower rate of incidence, hospitalization, and severity of COVID-19 in the hypertensive population.

The relationship between inflammation and venous thrombosis is not well understood. An inflammatory response may be both the cause and consequence of venous thromboembolism (VTE). In fact, several risk factors of VTE modulate thrombosis through inflammatory markers. Acute pulmonary embolism (PE) is burdened by a remarkable mortality rate, up to 34% in severely ill patients presenting with hemodynamic instability. Initial mortality risk stratification is based on hemodynamic instability. Patients with a situation of hemodynamic stability require immediate further risk assessment based on clinical, imaging, and circulating biomarkers, as well as the presence of comorbidities. Some inflammatory biomarkers have shown potential usefulness in the risk stratification of patients with VTE, especially acute PE. C-reactive protein on admission is associated with 30-day mortality and bleeding in VTE patients. P-selectin is associated with right ventricle dysfunction in PE patients and might be associated with VTE recurrences and the extension of thrombosis. Tissue factor microparticles are associated with VTE recurrence in cancer-associated thrombosis. Other inflammatory biomarkers present scarce evidence (inflammatory cytokines, erythrocyte sedimentation rate, fibrinogen, leukocyte count). In this manuscript, we will review the prognostic role of different inflammatory biomarkers available both for clinical practice and research in VTE patients.

Pacemakers (PM) and implantable cardioverter-defibrillators are vital devices in contemporary clinical practice, but their growing adoption poses challenges. Complications, including lead migration, infections, and post-implantation venous thrombosis, underscore the importance of comprehensive investigation. This retrospective observational study enrolled patients diagnosed with upper limb deep vein thrombosis (DVT) secondary to intracardiac devices at a tertiary hospital from 2015 to 2022. The aim of the study was to determine the incidence and long-term outcomes (bleeding, DVT recurrence and sequelae) in these patients. Across the study period, 2681 intracardiac devices were implanted, with 12 cases of upper limb DVT documented. The majority of patients were male (91.7%), with a mean age of 63.92 years. DVT occurred in patients with PM (50%), implantable cardioverter-defibrillators (25%) and implantable cardioverter-defibrillators with Cardiac Resynchronization Therapy (25%). Treatment encompassed low-molecular-weight heparin (91.7%) during the acute episode and long-term anticoagulation with direct oral anticoagulants (75%) or vitamin K antagonists (25%). Over a mean follow-up period of 33.17 months, half of the patients exhibited long-term sequelae, notably collateral circulation (66.7%). Remarkably, no thrombosis recurrences were observed during follow-up. However, one patient (8.3%) experienced a major bleeding event during treatment, and one patient (8.3%) required device removal (PM) due to persistent symptoms. This study revealed upper limb DVT occurred in 0.45% of patients after intracardiac device implantation. Rate of thrombosis recurrence was low during follow-up. Although half of the patients developed long-term sequelae, the need for prolonged anticoagulant therapy in these cases remains uncertain.
RESUMO
Background: Antigen carbohydrate 125 (CA-125) is a complex glycoprotein extensively studied as a prognostic biomarker in heart failure, yet its potential role in the short-term prognosis of an acute pulmonary embolism (PE) remains unexplored. Methods: In this observational, prospective, single-center study, consecutive patients aged 18 and older with a confirmed acute symptomatic PE and no history of prior anticoagulant therapy were enrolled. Primary and secondary objectives aimed to assess the prognostic capacity of CA-125 at PE diagnosis for 30-day mortality and major bleeding, respectively. Results: A total of 164 patients were included (mean age 69.8 years, SD 17), with 56.1% being male. Within 30 days, 17 patients (10.4%) died and 9 patients (5.5%) suffered major bleeding. ROC curve analysis for 30-day mortality yielded an area under the curve of 0.69 (95% CI 0.53-0.85) with an optimal CA-125 cut-off point of 20 U/mL and a negative predictive value of 96%. Multivariate analysis revealed a significant association between CA-125 levels exceeding 20 U/mL and 30-day mortality (adjusted odds ratio 4.95; 95% CI 1.61-15.2) after adjusting for age, cancer, NT-proBNP > 600 ng/mL, and the simplified pulmonary embolism severity index score. Survival analysis for 30-day mortality exhibited a hazard ratio of 5.47 (95% CI 1.78-16.8). No association between CA-125 levels and 30-day major bleeding was found. Conclusions: CA-125 emerges as a promising surrogate biomarker for short-term mortality prediction in an acute symptomatic PE. Future investigations should explore the integration of CA-125 into PE mortality prediction scores to enhance the prognostic accuracy in this patient population.
RESUMO
INTRODUCTION: The soluble urokinase-type plasminogen activator receptor (suPAR) potentially plays a role in immune-thrombosis, possibly by modulating plasmin activity or contributing to chemotaxis in a complex, poorly understood context. The role of suPAR levels in the short-term prognostic of patients with pulmonary embolism (PE) has not been evaluated. MATERIAL AND METHODS: This observational, prospective, single-center study enrolled consecutive patients aged 18 and above with confirmed acute symptomatic PE and no prior anticoagulant therapy. The primary objective was to assess the prognostic capacity of suPAR levels measured at the time of diagnosis in terms of mortality. RESULTS: Fifty-two patients, with a mean age of 73.8 years (±17), were included, with gender distribution evenly split at 50%. Seven (13.5%) patients died. The ROC curve for mortality yielded an AUC of 0.72 (95% CI 0.48-0.96), with an optimal suPAR cut-off of 5.5ng/mL. Bivariate analysis for suPAR>5.5ng/mL was associated with a crude odds ratio of 10 (95% CI 1.63-61.27; p=0.01) for 30-day mortality. Survival analysis showed a 30-day mortality hazard ratio of 8.33 (95% CI 1.69-40.99; p<0.01). CONCLUSION: suPAR emerges as a potential biomarker for short-term mortality prediction and holds the potential for enhanced stratification in patients with acute symptomatic PE.
RESUMO
BACKGROUND: This study aimed to validate the role of the D-dimer to lymphocyte ratio (DLR) for mortality prediction in a large national cohort of hospitalized coronavirus disease 2019 (COVID-19) patients. METHODS: A retrospective, multicenter, observational study that included hospitalized patients due to SARS-CoV-2 infection in Spain was conducted from March 2020 to March 2022. All biomarkers and laboratory indices analyzed were measured once at admission. RESULTS: A total of 10,575 COVID-19 patients were included in this study. The mean age of participants was 66.9 (±16) years, and 58.6% (6202 patients) of them were male. The overall mortality rate was 16.3% (n = 1726 patients). Intensive care unit admission was needed in 10.5% (n = 1106 patients), non-invasive mechanical ventilation was required in 8.8% (n = 923 patients), and orotracheal intubation was required in 7.5% (789 patients). DLR presented a c-statistic of 0.69 (95% CI, 0.68-0.71) for in-hospital mortality with an optimal cut-off above 1. Multivariate analysis showed an independent association for in-hospital mortality for DLR > 1 (adjusted OR 2.09, 95% CI 1.09-4.04; p = 0.03); in the same way, survival analysis showed a higher mortality risk for DLR > 1 (HR 2.24; 95% CI 2.03-2.47; p < 0.01). Further, no other laboratory indices showed an independent association for mortality in multivariate analysis. CONCLUSIONS: This study confirmed the usefulness of DLR as a prognostic biomarker for mortality associated with SARS-CoV-2 infection, being an accessible, cost-effective, and easy-to-use biomarker in daily clinical practice.

Mesenteric vein thrombosis (MVT) is a rare condition that can present acutely, subacutely, or chronically. MVT can be isolated or within a splanchnic thrombosis (spleno-porto-mesenteric). Symptomatic cases usually present as nonspecific abdominal pain, with or without signs of intestinal ischemia, and the diagnosis is usually made by imaging test (abdominal CT or MRI) in patients with high clinical suspicion. An early clinical-surgical approach is recommended to screen those patients with warning signs and who benefit from an exploratory laparotomy in addition to anticoagulant treatment, which is the cornerstone of medical treatment. MVT is usually associated with prothrombotic states, with hematological disorders (myeloproliferative syndromes and/or JAK2 gene mutations) being of special clinical relevance. On the other hand, the 5-year survival rate is 70-82% and early overall 30-day mortality from MVT can reach 20-32%.

INTRODUCTION: D-dimer has a high negative predictive value for the diagnosis of venous thromboembolic disease (VTE). However, VTE has been reported in the presence of normal D-dimer values. METHODS: This is a prospective observational study in patients with VTE from Hospital Gregorio Marañón between 2001 and 2022, comparing the characteristics of clinical presentation based on D-dimer levels (<500 ng/mL vs. ≥500 ng/mL). RESULTS: A total of 2582 patients were found, 333 patients (12.9%) presented negative or weakly positive D-dimer levels. They were significantly younger (57.9 vs. 65.3 years), with a lower prevalence of comorbidities (ischemic heart disease, dementia, and chronic kidney disease), and a greater family history of VTE (8.4% vs. 5.2%) and thrombophilia (11.7% vs. 7.8%). They presented significantly less dyspnea (57.6% vs. 75.4%), syncope (3% vs. 13.5%), less thrombotic load, elevated NT-pro-BNP (22.0% vs. 48.2%), and right ventricle dilatation (8.1% vs. 30.0%). CONCLUSION: Patients with VTE and low D-dimer levels at diagnosis were younger, with milder clinical presentation and lower thrombotic load; but they presented a higher prevalence of thrombophilia and a family history of VTE.

OBJECTIVE: To describe the baseline characteristics, clinical presentation, imaging tests and outcomes, and identify potential prognostic factors in a cohort of patients diagnosed with cerebral venous thrombosis (CVT). PATIENTS AND METHODS: This retrospective, single-center, observational study included adult patients diagnosed with CVT from January 2016 to December 2020. The variables were reviewed using electronic medical records. RESULTS: A total of 35 patients were included, with a median age at diagnosis of 50.3 (+/- 17.8) years, and the majority being women (74.4%). Nearly 95% of the patients presented at least one risk factor for the development of CVT. Heparins were used for the acute phase in 97.1% of cases, with 75% of those being low molecular weight heparins.During the first two weeks, a compound event (death, intensive care unit admission, National Institute of Health Stroke Scale at discharge >3, CVT recurrence, major bleeding, or the presence of complications) occurred in 28.6% of patients (10 patients).Over the mean follow-up period of 3.3 years, 14.3% of the patients died (with only one death attributed to CVT), one patient experienced major bleeding, and no patients had a recurrence of CVT. CONCLUSIONS: In our cohort, CVT predominantly affected young women with at least one risk factor for its development. The presence of edema on CT and corticosteroid treatment were associated with a poor short-term prognosis. However, we observed a favorable long-term prognosis in terms of mortality, recurrence, and bleeding.

We present an extremely rare case of a patient with intermediate-high risk pulmonary embolism treated with percutaneous mechanical thrombectomy, complicated with stroke as a form of paradoxical embolism through a previously unknown patent foramen ovale. We reviewed the literature for indications, efficacy, and safety of this procedure, as well as for experience on this technique in patients with patent foramen ovale. LEARNING POINTS: Some authors propose percutaneous mechanical thrombectomy as an aggressive treatment of intermediate-high risk pulmonary embolism.Pending clinical trials, percutaneous mechanical thrombectomy seems to reduce right ventricle overload in these patients, with rare adverse effects.To our knowledge, this is the first reported case of stroke as a complication of the procedure. These patients should be screened for patent foramen ovale before the procedure.
RESUMO
BACKGROUND: The real predictive prognostic capacity of cellular indices (or ratios) is unclear in SARS-CoV-2 infection. This study aimed to assess the prognostic role of previously well-known laboratory indices and new ones in hospitalized COVID-19 patients. METHODS: A retrospective observational study from March to May 2022 evaluated laboratory indices on admission (neutrophil to lymphocyte-, derived neutrophil to lymphocyte-, platelet to lymphocyte-, CRP to lymphocyte-, CRP to albumin-, fibrinogen to lymphocyte-, d-dimer to lymphocyte-, ferritin to lymphocyte-, LDH to lymphocyte-, and IL-6 to lymphocyte ratios), in patients hospitalized due to SARS-CoV2 infection to determine the association with mortality, admission to an intensive care unit (ICU), need for non-invasive mechanical ventilation (NIMV), orotracheal intubation (OTI), or combined event at 30 days follow-up. RESULTS: A total of 1113 COVID-19 patients were evaluated with a mean age of 64.1 ± 15.9 years (58.49% male), 166 (14.91%) patients died, 58 (5.21%) required ICU admission, 73 (6.56%) needed NIMV, 46 (4.23%) needed OTI, and 247 (22.19%) presented the combined event. All the ratios evaluated in this study showed statistical significance in the univariate analysis for mortality and combined event; however, only d-dimer to lymphocyte ratio >0.6 presented an independent association in the multivariate analysis for 30-day mortality (adjusted OR 2.32; p = .047) and 30-day combined event (adjusted OR 2.62; p = .014). CONCLUSIONS: Laboratory indices might be a potential biomarker for better prognosis stratification in hospitalized COVID-19 patients. d-Dimer to lymphocyte ratio presents an independent association for 30-day mortality and 30-day adverse outcomes in hospitalized COVID-19 patients.

OBJECTIVES: To analyze the prevalence of May-Thurner syndrome (MTS) among patients with deep vein thrombosis (DVT) of left lower limb (LLL), and outcomes after long-term follow-up. METHOD: Retrospective observational study that included patients older than 18 diagnosed with acute DVT and MTS. RESULTS: Among 760 patients diagnosed with DVT in the LLL, 8 patients were diagnosed with MTS (1.05%), with a mean age of 39 years. All patients received long-term anticoagulation, with a mean of 31.9 (±25.2) months. Invasive treatment with pharmaco-mechanical thrombectomy was performed in 5 patients (62.5%). During follow-up (mean of 32.4 months), 25% of patients suffered DVT recurrence. Only 1 case presented major bleeding, and no deaths were registered. CONCLUSIONS: May-Thurner syndrome constitutes a permanent and underdiagnosed risk factor for the development of DVT of LLL. Our findings suggest that long-term anticoagulation therapy might be considered in selected cases.

Mid-regional pro-adrenomedullin (MR-proADM), methemoglobin (MetHb), and carboxyhemoglobin (COHb) levels have been associated with sepsis. In this study, we assessed the role of this potential biomarkers in critically ill COVID-19 patients. Outcomes were mortality and a combined event (mortality, venous or arterial thrombosis, and orotracheal intubation (OTI)) during a 30-day follow-up. A total of 95 consecutive patients were included, 51.6% required OTI, 12.6% patients died, 8.4% developed VTE, and 3.1% developed arterial thrombosis. MetHb and COHb levels were not associated with mortality nor combined event. Higher MR-proADM levels were found in patients with mortality (median of 1.21 [interquartile range-IQR-0.84;2.33] nmol/L vs. 0.76 [IQR 0.60;1.03] nmol/L, p = 0.011) and combined event (median of 0.91 [IQR 0.66;1.39] nmol/L vs. 0.70 [IQR 0.51;0.82] nmol/L, p < 0.001); the positive likelihood ratio (LR+) and negative likelihood ratio (LR-) for mortality were 2.40 and 0.46, respectively. The LR+ and LR- for combined event were 3.16 and 0.63, respectively. MR-proADM ≥1 nmol/L was the optimal cut-off for mortality and combined event prediction. The predictive capacity of MR-proADM showed an area under the ROC curve of 0.73 (95% CI, 0.62-0.81) and 0.72 (95% CI, 0.62-0.81) for mortality and combined event, respectively. In conclusion, elevated on-admission MR-proADM levels were associated with higher risk of 30-day mortality and 30-day poor outcomes in a cohort of critically ill patients with COVID-19.

INTRODUCTION: Inferior vena cava agenesis (IVCA) is a rare and underdiagnosed congenital anomaly that predisposes to deep vein thrombosis (DVT). Optimal duration of anticoagulant treatment in these patients is not well established. METHOD: Observational retrospective study that included all consecutive patients older than 18 diagnosed with IVCA and DVT. Data including demographics, initial clinical presentation, modality of diagnosis, treatment and outcomes were obtained. RESULTS: In patients with IVCA and DVT (n = 9), mean age was 42 and 66% were males. Five (55,5%) patients had bilateral DVT and the most frequent location was ilio-femoral. Only one patient had concomitant pulmonary embolism (PE). During follow-up (mean of 77.8 months), anticoagulation was withdrawn in 2 patients and both developed recurrence of DVT (22.2%, CI 95% 2.8-60.0). One minor bleeding (11.1%, CI 95% 0.3-48.3), five post-thrombotic syndrome (55.6%, CI 95% 21.2-86.3) and no deaths were registered. CONCLUSION: In patients with DVT and IVCA, post-thrombotic syndrome was developed in approximately half of the patients. No major bleeding events were recorded during long-term anticoagulant therapy and recurrences occurred only in patients who had anticoagulation withdrawn. These data suggest that extended anticoagulant therapy might be considered in these patients.

Budd-Chiari syndrome (BCS) is characterized by an obstruction of hepatic venous outflow from small hepatic veins to inferior vena cava, caused by acute thrombosis or its fibrous sequellae. An underlying myeloproliferative neoplasm is present in 50% of cases. Clinical manifestations are widely variable, from asymptomatic to fulminant episodes. Long-term complications range from cirrhosis to hepatocellular carcinoma. Behçet's disease (BD) is a rare recurrent inflammatory multisystemic disorder characterized by recurrent skin-mucosa lesions and systemic involvement. Vascular involvement is observed in up to 40% of the patients with BD, and it is one of the major causes of mortality and morbidity. BCS is a rare complication of BD with a frequency of < 5% among patients with vascular involvement. Immunosuppressive treatment is the cornerstone for the management of vascular involvement in BD, while anticoagulant therapy has been an issue of debate. Transjugular intrahepatic portosystemic shunt (TIPS) in severe cases of BCS-of all causes- improves survival. However, there is scarce evidence about the role of TIPS in the setting of BCS in BD. We present a case of a vascular Behçet's disease associated with chronic Budd-Chiari syndrome with progression of thrombosis despite adequate anticoagulant and immunosuppressive treatment, successfully managed with TIPS.

A 43-year-old man with a history of severe extrinsic allergic asthma treated with once-monthly omalizumab (600 mg) for the last 15 months. He presented to the emergency room with a 2-week history of right lower limb pain and chest pleuritic pain. Computed tomography pulmonary angiography showed bilateral pulmonary embolism with right-sided pulmonary infarction and ultrasound of right lower limb confirmed distal deep vein thrombosis. No other known risk factors were identified. Treatment with omalizumab was stopped during hospitalization. The Naranjo Adverse Drug Reaction (ADR) Probability Scale classifies this as a probable ADR (score of 6). Omalizumab is a humanized monoclonal anti-IgE antibody indicated for the treatment of persistent moderate-to-severe asthma and certain chronic refractory urticaria. The EXCELS study (The Epidemiologic Study of Xolair (omalizumab): Evaluating Clinical Effectiveness and Long-term Safety in Patients with Moderate-to-Severe Asthma), a postmarketing observational cohort study to assess clinical safety profile of omalizumab, showed a significant increase in venous thromboembolism. In conclusion, omalizumab has been associated with arterial and venous thromboembolic events, although the evidence is not definitive.
