Associação do Nível de ST2 Solúvel com Mortalidade em 6 Meses e/ou Hospitalização Recorrente Relacionada a Doenças Cardiovasculares em Embolia Pulmonar / Association of soluble ST2 Level with 6-month Mortality and/or Recurrent Cardiovascular-Related Hospitalization in Pulmonary Embolism

Resumo Fundamento: A associação de supressão solúvel da tumorigênese-2 (sST2) com prognóstico em embolia pulmonar (EP) é desconhecida. Objetivo: Este estudo teve como objetivo investigar a relação entre os níveis de sST2 em pacientes com EP aguda e mortalidade em 6 meses e hospitalizações recorrentes. Métodos: Este estudo prospectivo incluiu 100 pacientes com EP aguda. Os pacientes foram classificados em dois grupos de acordo com a mortalidade em 6 meses e a presença de hospitalizações recorrentes relacionadas a doenças cardiovasculares. Dois grupos foram comparados. Um valor de p de 0,05 foi considerado estatisticamente significativo. Resultados: Os níveis de ST2 solúvel foram significativamente maiores no grupo com mortalidade e internações recorrentes. (138,6 ng/mL (56,7-236,8) vs. 38 ng/mL (26,3-75,4); p<0,001) O melhor limite de corte para níveis de sST2 na previsão de um desfecho composto de mortalidade em 6 meses e/ou a hospitalização recorrente relacionada a doenças cardiovasculares foi >89,9, com especificidade de 90,6% e sensibilidade de 65,2%, de acordo com a curva Receiver Operating Characteristic (área sob a curva = 0,798; IC 95%, 0,705-0,891; p <0,0001). Após ajuste para fatores de confusão que foram estatisticamente significativos na análise univariada ou para as variáveis correlacionadas com os níveis de sST2, nível de sST2 (OR = 1,019, IC 95%: 1,009-1,028, p 0,001) e proteína C reativa (PCR). (OR = 1,010, IC 95%: 1,001-1,021, p = 0,046) continuaram a ser preditores significativos de mortalidade em 6 meses e/ou hospitalização recorrente relacionada a doenças cardiovasculares no modelo de regressão logística múltipla através do método backward stepwise. Conclusões: O nível de ST2 solúvel parece ser um biomarcador para prever mortalidade em 6 meses e/ou hospitalização recorrente relacionada a doenças cardiovasculares em pacientes com EP aguda.

Abstract Background: The association of soluble suppression of tumorigenesis-2 (sST2) levels with prognosis in pulmonary embolism (PE) is unknown. Objective: This study aimed to investigate the relationship between sST2 levels in patients with acute PE and 6-month mortality and recurrent hospitalizations. Methods: This prospective study included 100 patients with acute PE. Patients were classified into two groups according to 6-month mortality and the presence of recurrent Cardiovascular-Related hospitalizations. Two groups were compared. A p-value of 0.05 was considered statistically significant. Results: Soluble ST2 levels were significantly higher in the group with mortality and recurrent hospitalizations. (138.6 ng/mL (56.7-236.8) vs. 38 ng/mL (26.3-75.4); p<0.001) The best cut-off threshold for sST2 levels in the prediction of a composite outcome of 6-month mortality and/or recurrent Cardiovascular-Related hospitalization was found to be >89.9 with a specificity of 90.6% and a sensitivity of 65.2%, according to the receiver operating characteristic curve (area under the curve = 0.798; 95% CI, 0.705-0.891; p <0.0001). After adjusting for confounding factors that were either statistically significant in the univariate analysis or for the variables correlated with the sST2 levels, sST2 level (OR = 1.019, 95% CI: 1.009-1.028, p 0.001) and C-reactive protein (CRP ) (OR = 1.010, 95% CI: 1.001-1.021, p = 0.046) continued to be significant predictors of 6-month mortality and/or recurrent Cardiovascular-Related hospitalization in the multiple logistic regression model via backward stepwise method. Conclusion: Soluble ST2 level seems to be a biomarker to predict 6-month mortality and/or recurrent Cardiovascular-Related hospitalization in patients with acute PE.

A mudança de paradigma no tratamento do tromboembolismo venoso grave / The paradigm shift in treatment of severe venous thromboembolism

Resumo A embolia pulmonar (EP) é a terceira maior causa de morte cardiovascular e a principal de morte evitável intra-hospitalar no mundo. O conceito PERT® (do inglês, pulmonary embolism response team) envolve seu diagnóstico e tratamento precoce e multidisciplinar. A trombose venosa profunda (TVP) é a sua causa inicial na maioria dos casos e é responsável por complicações como a recidiva tromboembólica, a síndrome pós-trombótica e a hipertensão pulmonar tromboembólica crônica. Uma abordagem inicial semelhante ao PERT nos casos de TVP ilíaco-femoral grave pode reduzir não apenas o risco imediato de EP e morte, mas também suas sequelas tardias. Novas técnicas percutâneas e aparatos de trombectomia mecânica para o tromboembolismo venoso (TEV) vêm demonstrando resultados clínicos encorajadores. Propomos o desenvolvimento de um conceito ampliado de resposta rápida ao TEV, que envolve não apenas a EP (PERT®) mas também os casos graves de TVP: o time de resposta rápida para o TEV (TRETEV®), ou do inglês Venous Thromboembolism Response Team (VTERT®).

Abstract Pulmonary embolism (PE) is the third leading cause of cardiovascular death and the main cause of preventable in-hospital death in the world. The PERT® (Pulmonary Embolism Response Team) concept involves multidisciplinary diagnosis and immediate treatment. Deep venous thrombosis (DVT) is the initial cause of most cases of PE and is responsible for complications such as chronic thromboembolic recurrence, postthrombotic syndrome, and chronic thromboembolic pulmonary hypertension. An aggressive approach to severe cases of iliofemoral DVT similar to the PERT® system can not only reduce the immediate risk of PE and death but can also reduce later sequelae. New percutaneous techniques and mechanical thrombectomy devices for venous thromboembolism (VTE) have shown encouraging clinical results. We propose the development of an expanded concept of rapid response to VTE, which involves not only PE (PERT®) but also severe cases of DVT: the Venous Thromboembolism Response Team (VTERT®).

Infarto pulmonar: signos que no debemos dejar pasar en TC de tórax sin contraste / Pulmonary infarction: the signs that we must not miss in chest CT without contrast

Resumen El infarto pulmonar (IP) resulta de la oclusión de las arterias pulmonares distales que generan isquemia, hemorragia y finalmente necrosis del parénquima pulmonar, siendo la causa más frecuente la embolia pulmonar (EP). El diagnóstico oportuno de IP permite el inicio precoz del tratamiento y el respectivo manejo de sostén, disminuyendo así la morbimortalidad asociada. El objetivo de esta revisión es remarcar la importancia de identificar aquellos signos, que en la tomografía computada (TC) sin contraste son altamente sensibles y específicos para el diagnóstico de IP. La TC de alta resolución constituye el método que más información aporta, pudiendo observar signos clásicos de IP como la opacidad en forma de cuña, opacidad con radiolucencia central y el signo del vaso nutricio; así como signos con alto valor predictivo negativo para IP, como la opacidad consolidativa con broncograma aéreo, sugestivo de otras patologías, ya sean infecciosas o tumorales.

Abstract Pulmonary infarction (PI) results from occlusion of the distal pulmonary arteries leading to ischemia, hemorrhage, and necrosis of the pulmonary parenchyma. The most common cause of pulmonary infarction is pulmonary embolism (PE). Early diagnosis of PI allows early initiation of treatment and supportive care, thus reducing the associated morbidity and mortality. This review aims to highlight the importance of identifying signs that are highly sensitive and specific for the diagnosis of PE even without IV contrast. High-resolution computed tomography (CT) is the method that provides the most information, as it observes classic signs of PI such as wedge-shaped opacity, central lucencies in peripheral consolidation, and the feeding vessel sign, as well as signs with high negative predictive value such as consolidating opacity with air bronchogram that are suggestive of other pathologies, whether infectious or tumoural.

Introduction: One of the most feared infective endocarditis (IE) complications associated with pacemaker is pulmonary embolism. We present the case of a patient with a current diagnosis of pacemaker-associated IE who presented symptoms of pulmonary embolism confirmed by imaging studies after percutaneous removal of the device. Objectives: to know the management and evolution, in-hospital and at 18 months of pulmonary embolism in the context of infective endocarditis associated with pacemaker. Materials and methods: Bibliographic search carried out in PubMed. Clinical case report: clinical evaluation, presentation of complementary studies, and treatment. Follow up on the case. Results: 68-year-old patient with a history of dual chamber permanent pacemaker implantation 2 years ago. Prolonged febrile syndrome with no apparent focus, with positive blood cultures for methicillin-resistant Staphylococcus aureus. The transesophageal echocardiogram showed multiple vegetations associated in right atrial with the catheters. Based on the history, physical examination, and findings in specific tests, the diagnosis of IE associated with DEIP could be achieved. Antibiotic treatment and complete percutaneous removal of the device were indicated. After the procedure, he presented sudden dyspnea, confirming the diagnosis of pulmonary embolism in a ventilation-perfusion scintigram study. She completed the antibiotic treatment (vancomycin for 6 weeks) and was discharged. During follow-up, there were no new infections or other complications. Conclusion: in our patient pulmonary embolism did not generate changes in in-hospital morbidity and mortality or in the 18-month follow-up.

Pulmonary embolism in pediatrics: A 10-year experience from a tertiary center in Brazil

ABSTRACT Introduction: Although still rare, pulmonary embolism (PE) in children has been increasing over the years. Data regarding this group of patients are still sparse, which contributes to the lack of standardized prophylaxis protocols and the misdiagnosis. This study aimed to determine the incidence of pediatric PE at a Brazilian tertiary hospital, describe clinical characteristics and identify possible risk factors. We also analyzed the diagnosis and management of PE. Methods: This was a retrospective review of tertiary Brazilian single-center data of all pediatric patients (0 - 18 years) with acute PE, diagnosed radiologically, from September 2009 to May 2019. Results: The incidence of PE was 3.3 cases per 10,000 hospitalized children. All the twenty-three cases had some risk factor identified and sixteen of them (69.5%) had more than one risk factor. The most important were central venous catheter (39.1%), malignancy (34.8%) and recent surgery (34.8%). Among the children with identifiable symptoms (69.5%), the most common was dyspnea (56.2%). Only one patient did not receive antithrombotic therapy because of the high bleeding risk and most patients (70.6%) were treated for 3 to 6 months. Among the nineteen patients alive at the end of the six-month follow-up, ten (52.6%) repeated the PE image control. Seven of them (70.0%) had complete or partial resolution of the thrombosis and none had worsening images. Conclusion: Our lower incidence than that of the current literature may reflect underdiagnosis due to low suspicion of PE. At least one risk factor was identified in all patients, which emphasizes the importance of increasing awareness of high-risk children.

Tromboembolismo pulmonar asociado a COVID-19 en paciente con síndrome de May-Thurner / COVID-19-associated Pulmonary Thromboembolism in a Patient with May-Thurner Syndrome

Introducción: El síndrome de May-Thurner es una enfermedad cuya prevalencia real es desconocida. Suele ser asintomática y las manifestaciones clínicas aparecen en el contexto de las complicaciones asociadas a la enfermedad. La aproximación diagnóstica se realiza por medio de imágenes, donde se identifican alteraciones patognomónicas que permiten descartar diagnósticos diferenciales. Se ha demostrado que la COVID-19 genera un estado protrombótico, que en contexto del síndrome de May-Thurner puede derivar en complicaciones tromboembólicas. Objetivo: Comparar la clínica y la posible relación de la enfermedad tromboembólica venosa en el curso de la COVID-19 en pacientes con SMT. Caso clínico: Mujer de 24 años, secretaria de profesión y residente en Bucaramanga. Presentó un cuadro clínico de 20 días de evolución que inició con rinorrea hialina, tos ocasional y mialgias; cinco días después manifestó fiebre no cuantificada y tos con expectoración hemoptoica. Conclusiones: Dentro de la fisiopatología de la infección por SARS-CoV-2 se desarrollan mecanismos procoagulantes, lo cual incrementa el riesgo de eventos trombóticos en pacientes con o sin factores de riesgo(AU)

Introduction: May-Thurner syndrome is a disease whose actual prevalence is unknown. It is usually asymptomatic and clinical manifestations appear in the context of complications associated with the disease. The diagnostic approach is performed by imaging, where pathognomonic alterations are identified to rule out differential diagnoses. It has been demonstrated that COVID-19 generates a prothrombotic state, which particularly in patients with May-Thurner syndrome would lead to thromboembolic complications. Objective: To compare the clinical and possible relationship of venous thromboembolic disease in the course of COVID-19 in patients with May-Thurner syndrome. Clinical case: 24-year-old woman, secretary by profession and resident in Bucaramanga, Colombia. She presented a clinical picture of 20 days of evolution that began with hyaline rhinorrhea, occasional cough and myalgias; five days later she manifested unquantified fever and cough with hemoptotic expectoration. Conclusions: Within the pathophysiology of SARS-CoV-2 infection, procoagulant mechanisms develop, which increases the risk of thrombotic events in patients with or without risk factors(AU)

The association between glycemia and clinical outcomes in patients with diabetes mellitus and pulmonary thromboembolism

ABSTRACT Objective: Various studies have shown that diabetes mellitus (DM) increases the risk of thrombosis in the venous system as well as in the arterial system. In this study, it was aimed to evaluate the association between admission blood glucose levels and clinical severity, recurrence, and mortality in pulmonary embolism in patients with DM. Materials and methods: This study was designed as a retrospective cross-sectional study. Patients with DM who were admitted to a tertiary care hospital due to pulmonary embolism (PE) between 2014 and 2019 were included. Demographic characteristics, radiological findings, clinical class of embolism, and mortality data were retrieved from hospital records. Patients with and without recurrent disease, as well as patients who survived and died, were compared. Also, patients were classified according to quartiles of admission blood glucose levels. The quartiles were compared in terms of mortality, clinical, class, and recurrence. Results: Two hundred ninety-three patients with DM and PE were included in the study. Patients with adverse outcome had significantly higher admission blood glucose levels (respectively, 197.9 ± 96.30 mg/dL vs. 170.7 ± 74.26 mg/dL; p = 0.03). Patients in the third and fourth quartile of admission blood glucose levels (>152 mg/dL) had significantly more severe disease with a higher proportion of massive and sub-massive PE and higher pro-BNP levels (respectively, p = 0.01 and 0.02). Conclusion: Non-survived patients and recurrent disease were associated with higher admission blood glucose levels. Also, patients with admission blood glucose levels higher than 152 mg/dL tend to have clinically more severe diseases.

Infarto pulmonar cavitado en mujer con lupus eritematoso sistémico asociado a síndrome antifosfolípido

Tanto lupus eritematoso sistémico como el síndrome antifosfolípido son enfermedades autoinmunes con potencial tromboembólico, sobre todo por la presencia de anticuerpos trombogénicos. El pulmón es un lugar común donde suele asentarse un trombo y generar una tromboembolia, a veces con posterior infarto y cavitación. Existen pocos estudios que informen un infarto pulmonar cavitado en un paciente con lupus asociado a síndrome antifosfolípido. Presentamos el caso de una mujer de 24 años con síntomas generales y lesión pulmonar derecha cavitada. Fue tratada inicialmente como infección tuberculosa o fúngica. La analítica y las imágenes orientaron y diagnosticaron lupus asociado a síndrome antifosfolípido, complicado con tromboembolismo pulmonar que luego pasó a cavitarse. La paciente mejoró considerablemente con anticoagulantes, corticoides y ciclofosfamida.

Both systemic lupus erythematosus and antiphospholipid syndrome are autoimmune diseases with thromboembolic potential, especially due to the presence of thrombogenic antibodies. The lung is a common place where a thrombus usually settles and generates a thromboembolism, sometimes with subsequent infarction and cavitation. There are few studies reporting cavitary pulmonary infarction in a patient with lupus associated with antiphospholipid syndrome. We present the case of a 24-year-old woman with general symptoms and cavitated right lung lesion. She was initially treated as tuberculous or fungal infection. Laboratory tests and images guided and diagnosed lupus associated with antiphospholipid syndrome, complicated by pulmonary thromboembolism that later became cavitated. The patient improved considerably with anticoagulants, corticosteroids, and cyclophosphamide.

Double Outlet Right Ventricle Infective Endocarditis: A Rare Combination and a Therapeutic Challenge

Infective endocarditis involving the right side of the heart occurs rarely and often involves the tricuspid valve. The isolated pulmonary valve infective endocarditis (IPVIE) is a less common condition that occurs in specific population. The double outlet right ventricle (DORV) is an unusual congenital heart disease. The association of DORV and IPVIE darkens the prognosis. We report two cases of the association of DORV and IPVIE. The transthoracic echocardiography (TTE) is the base to the diagnosis. Right sided infective endocarditis in the lack of a guided strategy remains a therapeutic challenge.

Síndrome de Nicolau / Nicolau syndrome

Resumen El síndrome de Nicolau es una complicación infrecuente de la aplicación parenteral de diversos fármacos.

Recibió tratamiento con enoxaparina y cilostazol con posterior mejoría.

Abstract Nicolau syndrome is a rare complication of the parenteral application of various drugs. It is char acterized by the appearance of pain, followed by edema, erythema, and then a necrotic plaque. We present the case of a 31-year-old male with this syndrome, after the application of intramuscular benzathine penicillin. The diagnosis was supported by the biopsy. He received treatment with enoxaparin and cilostazol with subsequent improvement.

Cardiogenic shock due to pulmonary thromboembolism: the role of surgical thrombectomy / Shock cardiogénico debido a tromboembolismo pulmonar: el papel de trombectomía quirúrgica

Abstract A 53-year-old male patient with history of repaired hernia, who is admitted for 5 days of progressive dyspnea with diagnosis of abdominal sepsis, a computed tomography angiography was made, revealing pulmonary embolism in bilateral main pulmonary artery, and cardiac thrombectomy was performed.

Resumen Paciente masculino de 53 años de edad con historial de reparación de hernia, quien fue ingresado por presentar 5 días de disnea progresiva con diagnóstico de sepsis abdominal, se le realizó una angiografía por tomografía computada, revelando embolismo bilateral arteria pulmonar principal, se realizó una trombectomía cardíaca.

The Effect of Perioperative Fluid Management and Operative Modifications on Mortality and Morbidity in Patients Undergoing Pulmonary Endarterectomy

ABSTRACT Introduction: Chronic thromboembolic pulmonary hypertension (CTEPH) is a severe disease treated with pulmonary endarterectomy. Our study aims to reveal the differences in liquid modalities and operation modifications, which can affect the patients' mortality and morbidity. Methods: One hundred twenty-five patients who were diagnosed with CTEPH and underwent pulmonary thromboendarterectomy (PTE) at our center between February 2011 and September 2013 were included in this retrospective study with prospective observation. They were in New York Heart Association functional class II, III, or IV, and mean pulmonary artery pressure was > 40 mmHg. There were two groups, the crystalloid (Group 1) and colloid (Group 2) liquid groups, depending on the treatment fluids. P-value < 0.05 was considered statistically significant. Results: Although the two different fluid types did not show a significant difference in mortality between groups, fluid balance sheets significantly affected the intragroup mortality rate. Negative fluid balance significantly decreased mortality in Group 1 (P<0.01). There was no difference in mortality in positive or negative fluid balance in Group 2 (P>0.05). Mean duration of stay in the intensive care unit (ICU) for Group 1 was 6.2 days and for Group 2 was 5.4 days (P>0.05). Readmission rate to the ICU for respiratory or non-respiratory reasons was 8.3% (n=4) in Group 1 and 11.7% (n=9) in Group 2 (P>0.05). Conclusion: Changes in fluid management have an etiological significance on possible complications in patient follow-up. We believe that as new approaches are reported, the number of comorbid events will decrease.

Surgical Management of Massive Pulmonary Embolism Presenting with Cardiopulmonary Arrest: How Far Is Too Far?

ABSTRACT The incidence of diagnosed massive pulmonary embolism presenting to the Emergency Department is between 3% and 4.5% and it is associated with high mortality if not intervened timely. Cardiopulmonary arrest in this subset of patients carries a very poor prognosis, and various treating pathways have been applied with modest rate of success. Systemic thrombolysis is an established first line of treatment, but surgeons are often involved in the decision-making because of the improving surgical pulmonary embolectomy outcomes.

Presentations of pulmonary embolism in COVID-19: An Indian case series

The prevalence of pulmonary embolism (PE) among COVID-19 infections is significantly high. However, in resource-limited settings, appropriate computed tomography (CT) imaging is not possible for all COVID-19 patients. Very sick patients suspected of a PE may not be fit to be shifted to the CT room. Hence, it is likely that PE is underdiagnosed in Indian COVID-19 patients. Coexisting PE should be considered in all patients with influenza-like illnesses who have a Type 1 respiratory failure out of proportion to the severity of COVID-19 radiology. In this case series, we discuss the different presentations of PE in patients with COVID-19.

Embolia por colesterol en miembros inferiores: reporte de caso

La embolia por cristales de colesterol es efecto de la desestabilización de una placa de ateroma tras un evento desencadenante, produciendo la migración de cristales de colesterol hasta arteriolas periféricas, desencadenando un proceso inflamatorio endotelial; el espectro clínico varía desde ser asintomático hasta con un compromiso multiorgánico; la sospecha diagnóstica es principalmente clínica y será la biopsia de piel por su fácil accesibilidad, la que confirme el diagnóstico. El tratamiento es aún controvertido y no existe un consenso de las medidas terapéuticas para aplicar. A continuación, se presenta el caso de un paciente varón de 72 años de edad con una ateroembolia por cristales de colesterol en miembros inferiores, secundaria a una manipulación endovascular por angioplastia previa.

Cholesterol crystal embolism is the effect of the destabilization of an atherosclerotic plaque after a triggering event, producing the migration of cholesterol crystals to peripheral arterioles, triggering an endothelial inflammatory process; the clinical spectrum varies from being asymptomatic to having multiple organ involvement; diagnostic suspicion is mainly clinical and the skin biopsy will confirm the diagnosis due to its easy accessibility. The treatment is still controversial and there is no consensus on the therapeutic measures to apply. Below is the case of a 72-year-old male patient with atheroembolism due to cholesterol crystals in the lower limbs, secondary to endovascular manipulation by prior angioplasty.
