RESUMO

La trombosis venosa cerebral forma parte de las llamadas trombosis en sitios inusuales. Se define como una oclusión en el territorio venoso cerebral. Su incidencia se encuentra en aumento progresivo, especialmente en países en vías de desarrollo. Se observa con más frecuencia en mujeres jóvenes, siendo los factores hormonales, como el embarazo o la anticoncepción hormonal, factores de riesgo principales en el desarrollo de esta afección. La clínica va a depender fundamentalmente de la topografía de la trombosis, con un diagnóstico de confirmación basado principalmente en las pruebas de imagen. El tratamiento consiste generalmente en la anticoagulación, pudiendo plantearse otras opciones según la gravedad del cuadro. En general, el pronóstico es mejor que el de otros trastornos vasculares intracraneales. En esta revisión se describe la evidencia actual disponible acerca de la trombosis venosa cerebral.(AU)


Cerebral venous thrombosis is part of the so-called thrombosis in unusual sites. It is defined as an occlusion in the cerebral venous territory. Its incidence is progressively increasing, especially in developing countries. It is more frequently observed in young women, with hormonal factors such as pregnancy or hormonal contraception being significant risk factors in the development of this condition. The clinical presentation will depend fundamentally on the topography of the thrombosis, with a confirmatory diagnosis based mainly on imaging tests. The treatment generally consists of anticoagulation, and other options may be considered depending on the severity of the case. Overall, the prognosis is better than that of other intracranial vascular disorders. This review describes the current evidence available regarding cerebral venous thrombosis.(AU)

RESUMO

Introduction: Although older adults represent a significant proportion of patients with venous thromboembolism (VTE), the data on the impact of age-related differences in the clinical presentation, management, and outcomes of VTE are scarce. Methods: We analyzed data from the RIETE registry database, an ongoing global observational registry of patients with objectively confirmed VTE, to compare patient characteristics, clinical presentation, treatments, and outcomes between elderly (≥70 years) vs. non-elderly (<70 years) patients. Results: From January 2001 to March 2021, 100,000 adult patients were enrolled in RIETE. Elderly patients (47.9%) were more frequently women (58.2% vs. 43.5%), more likely had unprovoked VTE (50.5% vs. 45.1%) and most often presented with severe renal failure (10.2% vs. 1.2%) and acute pulmonary embolism (PE) (vs. deep vein thrombosis) (54.3% vs. 44.5%) compared to non-elderly patients (p<0.001 for all comparisons). For the PE subgroup, elderly patients more frequently had non-low risk PE (78.9% vs. 50.7%; p<0.001), respiratory failure (33.9% vs. 21.8%; p<0.001) and myocardial injury (40.0% vs. 26.2%; p<0.001) compared to non-elderly patients. Thrombolysis (0.9% vs. 1.7%; p<0.001) and direct oral anticoagulants (8.8% vs. 11.8%; p<0.001) were less frequently administered to elderly patients. Elderly patients showed a significantly higher 30-day all-cause mortality (adjusted odds ratio [OR] 1.36, 95%CI: 1.22–1.52) and major bleeding (OR, 2.08; 95%CI, 1.85–2.33), but a lower risk of 30-day VTE recurrences (OR, 0.62, 95%CI, 0.54–0.71). Conclusions: Compared with non-elderly patients, elderly patients had a different VTE clinical profile. Advanced therapies were less frequently used in older patients. Age was an independent predictor of mortality.(AU)

RESUMO

Background and aim: This was a systematic review and meta-analysis of the prevalence of thromboembolic events in children and adolescents with antiphospholipid syndrome (APS). Methods: We searched PubMed, EMBASE and Web of Science to select relevant articles published between 1 January 2000 and 27 February 2022. We used the random-effects meta-analysis to estimate pooled point prevalence rates of thromboembolic events in studies with a minimum sample size of 30. Results: We included five studies reporting data of 336 children and adolescents with primary APS and secondary APS (SAPS). Pooled point prevalence rates of initial general thrombosis, arterial thrombosis, venous thrombosis and stroke in individuals with seropositive APS were 98.2% (95% confidence interval [CI] 87.5–100), 27.6% (95% CI 21.4–34.2), 51.1% (95% CI 38.2–63.9) and 13.4% 95% CI (6.3–22.7), respectively. Pooled point prevalence rates of initial arterial and venous thromboses in children and adolescents with SAPS were 45.7% (95% CI 21.1–71.6) and 29.2% (95% CI 14.8–46), respectively. Conclusion: Arterio-venous thromboembolism is highly frequent in children and adolescents with SAPS. More studies using thrombotic and non-thrombotic APS classification criteria are warranted to better assess the frequency and predictors of thromboembolism in age- and ancestry-diverse pediatric populations affected by different types of APS.(AU)


Antecedentes y objetivo: Se trata de una revisión sistemática y un metaanálisis de la prevalencia de acontecimientos tromboembólicos en niños y adolescentes con síndrome antifosfolípido (SAF). Métodos: Se realizaron búsquedas en PubMed, EMBASE y Web of Science para seleccionar los artículos pertinentes publicados entre el 1 de enero de 2000 y el 27 de febrero de 2022. Se utilizó el metaanálisis de efectos aleatorios para estimar las tasas de prevalencia puntual agrupadas de eventos tromboembólicos en estudios con un tamaño muestral mínimo de 30. Resultados: Se incluyeron cinco estudios con datos de 336 niños y adolescentes con APS primario y APS secundario (SAPS). Las tasas de prevalencia puntual agrupadas de trombosis general inicial, trombosis arterial, trombosis venosa e ictus en individuos con SAF seropositivo fueron de 98,2% (intervalo de confianza [IC] 95%: 87,5-100), 27,6% (IC 95%: 21,4-34,2), 51,1% (IC 95%: 38,2-63,9) y 13,4% (IC 95%: 6,3-22,7), respectivamente. Las tasas de prevalencia puntual agrupadas de trombosis arteriales y venosas iniciales en niños y adolescentes con SAF secundario fueron de 45,7% (IC 95%: 21,1-71,6) y de 29,2% (IC 95%: 14,8-46), respectivamente. Conclusión: La tromboembolia arteriovenosa es muy frecuente en niños y adolescentes con SAF. Se justifica la realización de más estudios que utilicen criterios de clasificación del SCA trombótico y no trombótico para evaluar mejor la frecuencia y los factores predictivos de la tromboembolia en poblaciones pediátricas de edad y ascendencia diversas afectadas por distintos tipos de SCA.(AU)

RESUMO

Objetivo: comparar la frecuencia de eventos tromboembólicos agudos en pacientes atendidos en urgencias de un hospital comarcal durante las primeras semanas de la pandemia de COVID-19 del año 2020 respecto al año anterior.Material y métodos: estudio retrospectivo en pacientes mayores de 40 años atendidos en urgencias del Hospital de Riotinto (Huelva) desde el 15 de marzo al 30 de abril de los años 2019 y 2020. La recogida de información se llevó a cabo a partir de una revisión de historias clínicas y el cuestionario de recogida de datos contenía variables clínicas y sociodemográficas.Resultados: se incluyeron 1.245 pacientes. Edad media: 71,2 años (desviación estándar [DE]: 13,7) y un 51,1% eran mujeres. En 2019 se atendieron a 797 mayores de 40 años y en 2020 fueron 448, suponiendo un descenso del 43,79%. La prevalencia de embolismo pulmonar fue superior en 2020 respecto a 2019 (1,6% frente a 0,4%; p = 0,024). La frecuencia de eventos trombóticos venosos fue superior también en 2020 respecto a 2019 (1,35% frente a 0,4%; p = 0,054). La prevalencia global de la enfermedad tromboembólica venosa con variable compuesta (tromboembolismo pulmonar + trombosis venosa) fue significativamente superior en 2020 frente a 2019 (2,9% frente a 0,8%; p = 0,003). Ningún paciente fue diagnosticado de COVID-19 y tromboembolismo.Conclusiones: en el período de confinamiento durante la pandemia hubo un incremento del número de eventos tromboembólicos agudos en adultos, tanto de tromboembolia pulmonar como de trombosis venosa profunda respecto al año previo. (AU)


Aim: to compare the frequency of acute thromboembolic events in patients visited in the casualty department of a regional hospital during the first few weeks of the COVID-19 pandemic in 2020 with the same period of previous year.Material and methods: retrospective study of patients aged over 40 years of age treated in the casualty department of Hospital de Riotinto (Huelva) from 15 March to 30 April 2019 and same period of 2020. The information was collected from a review of medical records. The data collection questionnaire contained clinical and sociodemographic variables.Results: a total of 1245 patients were included. Mean age was 71.2 (SD:13.7) years old and 51.1% were women. In 2019, 797 patients aged over 40 years of age were treated, while in 2020, the patients seen were 448, which represented a decrease of 43.79%. The prevalence of pulmonary embolism was higher in 2020 compared to 2019 (1.6% vs. 0.4%; P=0.024). The frequency of venous thrombotic events was also higher in 2020 compared to 2019 (1.35% vs. 0.4%; P=0.054). The overall prevalence of venous thromboembolic disease with composite variable (pulmonary thromboembolism + venous thrombosis) was statistically significantly higher in 2020 versus 2019 (2.9% versus 0.8%; P=0.003). None of our patients were diagnosed with COVID-19 and thromboembolism.Conclusions: during the period of confinement during the pandemic there was an increase in the number of acute thromboembolic events in adults, both PE and VTE compared to the previous year.(AU)

RESUMO

Background Patients with nephrotic syndrome are at high risk of venous thromboembolism (VTE), especially for primary membranous nephropathy (PMN). The phospholipase A2 receptor (PLA2R) is a marker of primary membranous nephropathy activity. This study investigated the predictive value of PLA2R antibodies in PMN for VTE.Methods In this retrospective study, we included 97 PMN patients and evaluated the predictive value of serum PLA2R antibodies for VTE risk. Lower extremity venous ultrasound, renal vein ultrasound, or spiral computed tomography pulmonary arteriography were used to assess VTE events. Serum anti-PLA2R antibodies were detected by enzyme-linked immunosorbent assay (ELISA). The risk of VTE was stratified according to serum albumin levels. Results Twenty PMN patients (21%) had thromboembolic events. Eight (15%) of patients with serum albumin >25g/l developed VTE, 6 of whom were positive for serum PLA2R antibodies. Positive serum PLA2R antibodies were significantly associated with VTE events in patients with serum albumin >25g/l (p=0.01). Age, sex, blood creatinine, serum albumin, and 24-h urine protein levels were not statistically different between the two groups. Kaplan–Meier analysis using the log-rank test revealed anti-PLA2R positive membranous nephropathy patients had more probability of VTE events than anti-PLA2R negative patients. Univariate Cox proportional hazards analysis revealed that lnPLA2R-Ab is an unfavorable predictor for VTE events in patients with serum albumin >25g/l (hazard ratio (HR) 2.1, p=0.01). Conclusions The PLA2R antibody was a risk predictor for thromboembolic events in patients with primary membranous nephropathy with serum albumin >25g/l (AU)


Antecedentes Los pacientes con síndrome nefrótico presentan un alto riesgo de tromboembolia venosa (TEV), especialmente en el caso de la nefropatía membranosa primaria (NMP). El receptor de fosfolipasa A2 (PLA2R) es un marcador de la actividad de la NMP. Este estudio investigó el valor predictivo de los anticuerpos PLA2R en NMP para TEV. Métodos En este estudio retrospectivo, se incluyeron 97 pacientes con NMP y se evaluó el valor predictivo de los anticuerpos PLA2R en suero para el riesgo de TEV. Se utilizaron la ecografía venosa de las extremidades inferiores, la ecografía de la vena renal o la arteriografía pulmonar por tomografía computarizada en espiral para evaluar los episodios de TEV. Los anticuerpos séricos anti-PLA2R se detectaron mediante un ensayo inmunoenzimático (ELISA). El riesgo de TEV se estratificó en función de los niveles de albúmina sérica. Resultados Veinte pacientes con NMP (21%) presentaron episodios tromboembólicos. Ocho (15%) de los pacientes con albúmina sérica>25g/l desarrollaron TEV, 6 de los cuales fueron positivos para anticuerpos PLA2R séricos. La positividad de los anticuerpos PLA2R séricos se asoció significativamente con episodios de TEV en pacientes con albúmina sérica>25g/l (p=0,01). La edad, el sexo, la creatinina en sangre, la albúmina sérica y los niveles de proteínas en orina de 24h no fueron estadísticamente diferentes entre los 2 grupos. El análisis de Kaplan-Meier mediante la prueba de rangos logarítmicos reveló que los pacientes con nefropatía membranosa positivos para anti-PLA2R tenían más probabilidad de sufrir TEV que los pacientes negativos para anti-PLA2R. El análisis univariante de riesgos proporcionales de Cox reveló que ln PLA2R-Ab es un predictor desfavorable de episodios de TEV en pacientes con albúmina sérica>25g/l (hazard ratio 2,1; p=0,01). Conclusiones El anticuerpo PLA2R fue un predictor de riesgo de episodios tromboembólicos en pacientes con NMP con albúmina sérica>25g/l (AU)

RESUMO

Introducción La cirugía reciente es un factor de riesgo transitorio mayor y conocido de tromboembolia venosa (TEV) debido al bajo riesgo de recurrencia de la TEV una vez suspendida la anticoagulación. Por otro lado, se desconoce el riesgo de recurrencia de la TEV en los pacientes con TEV asociada a COVID-19. El objetivo de este estudio consistió en comparar el riesgo de recurrencia de la TEV entre pacientes con TEV asociada a COVID-19 y a cirugía. Método Se realizó un estudio prospectivo, observacional y unicéntrico en el que participaron pacientes consecutivos diagnosticados de TEV en un hospital terciario entre enero de 2020 y mayo de 2022 y que fueron objeto de seguimiento durante un mínimo de 90 días. Se evaluaron las características iniciales, el cuadro clínico y los resultados clínicos. Se compararon las incidencias de recurrencia de la TEV, hemorragias y muertes entre ambos grupos. Resultado En el estudio se incluyó a un total de 344 pacientes: 111 con TEV asociada a cirugía y 233 con TEV asociada a COVID-19. Entre los pacientes con TEV asociada a COVID-19 hubo una mayor frecuencia de varones (65,7 vs. 48,6%, p = 0,003). La recurrencia de la TEV fue de 3% en los pacientes con COVID-19 y de 5,4% en los pacientes quirúrgicos, sin diferencias significativas (p = 0,364). La tasa de incidencia de TEV recurrente fue de 1,25 y 2,29 por 1.000 personas-meses en los pacientes con COVID-19 y quirúrgicos, respectivamente, sin diferencias significativas (p = 0,29). En el análisis multifactorial, la COVID-19 se asoció a una mayor mortalidad (HR = 2,34; IC 95%, 1,19-4,58), pero no a un mayor riesgo de recurrencia (HR = 0,52; IC 95%, 0,17-1,61). En el análisis multifactorial de riesgos competitivos no se observaron diferencias en cuanto a recurrencias (SHR = 0,82; IC 95%, 0,40-2,05). Conclusiones El riesgo de recurrencia fue bajo en los pacientes con TEV asociada a COVID-19 y a cirugía, sin diferencias entre ambos grupos (AU)


Introduction Recent surgery is a well-known major transient risk factor for venous thromboembolism (VTE) due to the low risk of VTE recurrence after anticoagulation is discontinued. On the other hand, the risk of VTE recurrence among patients with COVID-19-associated VTE is unknown. This study aimed to compare the risk of VTE recurrence between patients with COVID-19- and surgery-associated VTE. Methods A prospective observational single-center study was performed including consecutive patients diagnosed with VTE in a tertiary hospital from January 2020 to May 2022 and followed up for at least 90 days. Baseline characteristics, clinical presentation, and outcomes were assessed. The incidence of VTE recurrence, bleeding, and death was compared between both groups. Result A total of 344 patients were included in the study: 111 patients with surgery-associated VTE and 233 patients with COVID-19-associated VTE. Patients with COVID-19-associated VTE were more frequently men (65.7% vs 48.6%, p = 0.003). VTE recurrence was 3% among COVID-19 patients and 5.4% among surgical patients, with no significant differences (p = 0.364). The incidence rate of recurrent VTE was 1.25 per 1000 person-months in COVID-19 patients and 2.29 person-months in surgical patients, without significant differences (p = 0.29). In the multivariate analysis, COVID-19 was associated with higher mortality (HR 2.34; 95% CI 1.19-4.58), but not with a higher risk of recurrence (HR 0.52; 95% CI 0.17-1.61). No differences were found in recurrence in the multivariate competing risk analysis (SHR 0.82; 95% CI 0.40 – 2.05). Conclusions In patients with COVID-19 and surgery-associated VTE, the risk of recurrence was low, with no differences between both groups (AU)

RESUMO

Introduction: Direct oral anticoagulants (DOACs) could effectively prevent the occurrence of cancer-associated venous thromboembolism (CAVTE), which incidence rate was estimated to be 4–20%. But the efficacy and safety remain controversial between DOACs and low molecular weight heparin (LMWH).Materials and methodsPubMed, Cochrane Library, Embase, ClinicalTrials.gov databases for randomized controlled trials (RCTs) were systematically searched from inception to March 15, 2022. A random-effects model was used to report the odds ratio (OR) and 95% confidence interval (CI) for both direct and network meta-analyses.ResultsSeven studies were included totaling 3242 patients. A lower rate of recurrence VTE was noted in the DOACs compared with LMWH (OR 0.62, 95% CI 0.47–0.82, I2=0.0%). The aspect of major bleeding (MB) was similar (OR 1.30, 95% CI 0.77–2.18, I2=34.9%). When assessing clinically relevant nonmajor bleeding (CRNMB) (OR 1.61, 95% CI 1.17–2.22, I2=20.7%) and clinically relevant bleeding (CRB) (OR 1.39, 95% CI 1.11–1.74, I2=0.0%), a higher risk of events was observed in DOACs. In subgroup analyses, the MB of gastrointestinal and genitourinary malignancies had a higher rate in the DOACs. For ranking, apixaban ranked the first in prevention of VTE and reducing MB events. Edoxaban had the highest risk drug in MB. In terms of CRNMB and CRB, LMWH showed the lowest risk.ConclusionsCompared with LMWH, DOACs seemed to have a decreased risk of recurrence VTE while increasing CRNMB and CRB. DOACs and LMWH were equivalent to the aspect of MB, but DOACs had a higher MB risk in patients with gastrointestinal and genitourinary malignancies. Apixaban may be the lowest risk compared to the other DOACs in precaution of VTE and reducing bleeding events. (AU)


Introducción: Los anticoagulantes orales directos (ACOD) son eficaces en la prevención de la tromboembolia venosa (TEV) relacionada con el cáncer, cuya tasa de incidencia se estima en 4-20%. Sin embargo, la eficacia y seguridad de ACOD y heparina de bajo peso molecular (HBPM) siguen siendo controvertidas.Materiales y métodosDesde el inicio hasta el 15 de marzo de 2022 se realizaron búsquedas sistemáticas en las bases de datos de ensayos controlados aleatorios (ECA) en PubMed, The Cochrane Library, Embase, ClinicalTrials.gov. Se utilizó el modelo de efectos aleatorios para informar la razón de probabilidades (RP) y los intervalos de confianza (IC) de 95% para los metaanálisis directos y de red.ResultadosSe incluyeron siete estudios con un total de 3.242 pacientes. En comparación con HBPM, los ACOD tienen una tasa más baja de recurrencia de TEV (OR 0,62, IC 95%: 0,47 a 0,82, I2 = 0,0%). La frecuencia de hemorragias mayores fue similar (OR 1,30, IC 95% 0,77 a 2,18, I2 = 34,9%). Se observó un mayor riesgo de eventos en los ACOD. Cuando se evaluaron las hemorragias no mayores clínicamente relevantes (CRNMB) (OR 1,61, IC 95%: 1,17 a 2,22, I2 = 20,7%) y las hemorragias clínicamente relevantes (OR 1,39, IC 95%: 1,11 a 1,74, I2 = 0,0%), En los análisis de subgrupos, las hemorragias mayores en las neoplasias malignas gastrointestinales y genitourinarias fueron más frecuentes con los ACOD. Apixabán ocupó el primer lugar en la prevención de TEV y la reducción de eventos hemorrágicos mayores. Edoxabán tuvo el mayor riesgo de hemorragias mayores. Las HBPM demostraron tener menor riesgo de hemorragias mayores clínicamente relevantes y hemorragias clínicamente relevantes. (AU)

RESUMO

Introducción: El dímero-D presenta un elevado valor predictivo negativo (VPN) para el diagnóstico de enfermedad tromboembólica venosa (ETV). Sin embargo, se ha descrito ETV en presencia de valores normales de dímero-D.Pacientes y métodosEstudio observacional prospectivo en pacientes con ETV en el Hospital Gregorio Marañón entre 2001-2022 que compara las características de presentación clínica en función de los niveles de dímero-D (< 500 ng/mL vs. ≥ 500 ng/mL).ResultadosDel total de 2.582 pacientes, 333 pacientes (12,9%) presentaron dímero-D negativo o débilmente positivo. Estos eran significativamente más jóvenes (57,9 vs. 65,3 años), con menor prevalencia de comorbilidades (cardiopatía isquémica, demencia y enfermedad renal crónica), mayor historia familiar de ETV (8,4% vs. 5,2%) y trombofilia (11,7% vs. 7,8%). Presentaron significativamente menor disnea (57,6% vs. 75,4%), síncope (3% vs. 13,5%), menor carga trombótica, elevación de Nt-pro-BNP (22,0% vs. 48,2%) y dilatación del ventrículo derecho (8,1% vs. 30,0%).ConclusiónLos pacientes con ETV y niveles bajos de dímero-D al diagnóstico fueron más jóvenes, con presentación clínica más leve y menor carga trombótica; pero presentaron mayor prevalencia de trombofilia e historia familiar de ETV.

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.MethodsThis 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).ResultsA 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%).ConclusionPatients 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.

RESUMO

Objective To evaluate the rate of thrombosis, bleeding and mortality comparing anticoagulant doses in critically ill COVID-19 patients. Design Retrospective observational and analytical cohort study. Setting COVID-19 patients admitted to the intensive care unit of a tertiary hospital between March and April 2020. Patients 201 critically ill COVID-19 patients were included. Patients were categorized into three groups according to the highest anticoagulant dose received during hospitalization: prophylactic, intermediate and therapeutic. Interventions The incidence of venous thromboembolism (VTE), bleeding and mortality was compared between groups. We performed two logistic multivariable regressions to test the association between VTE and bleeding and the anticoagulant regimen. Main variables of interest VTE, bleeding and mortality. Results 78 patients received prophylactic, 94 intermediate and 29 therapeutic doses. No differences in VTE and mortality were found, while bleeding events were more frequent in the therapeutic (31%) and intermediate (15%) dose group than in the prophylactic group (5%) (p<0.001 and p<0.05 respectively). The anticoagulant dose was the strongest determinant for bleeding (odds ratio 2.4, 95% confidence interval 1.26–4.58, p=0.008) but had no impact on VTE. Conclusion Intermediate and therapeutic doses appear to have a higher risk of bleeding without a decrease of VTE events and mortality in critically ill COVID-19 patients (AU)


Objetivo Evaluar la incidencia de eventos trombóticos, sangrado y mortalidad comparando diferentes regímenes de anticoagulación en pacientes ingresados en unidades de Cuidados Intensivos (UCI) por COVID-19. Diseño Estudio de cohortes retrospectivo observacional y analítico. Ámbito Pacientes con COVID-19 ingresados en una UCI de un hospital terciario entre marzo y abril del 2020. Pacientes Se incluyó a un total de 201 pacientes de UCI ingresados por COVID-19. Los pacientes se categorizaron en 3 grupos en función de la dosis de anticoagulación más alta recibida durante el ingreso: profiláctica, intermedia y terapéutica. Intervenciones Se comparó la incidencia de eventos trombóticos, hemorragia y mortalidad entre los grupos. Se realizaron 2 regresiones logísticas multivariables para comprobar la asociación entre los eventos trombóticos y el sangrado con el régimen anticoagulante. Principales variables de interés Eventos trombóticos, sangrado y mortalidad. Resultados De los pacientes incluidos, 78 recibieron dosis profilácticas, 94 intermedias y 29 terapéuticas. No se encontraron diferencias en los eventos trombóticos y la mortalidad entre grupos, mientras que los sangrados fueron más frecuentes en el grupo de dosis terapéutica (31%) e intermedia (15%) que en el grupo de dosis profiláctica (5%) (p <0,001 y p <0,05, respectivamente). El régimen anticoagulante fue el mayor determinante de sangrado (odds ratio 2,4;, intervalo de confianza del 95%, 1,26-4,58; p=0,008) pero no tuvo ningún impacto en los eventos trombóticos. Conclusiones Las dosis intermedias y terapéuticas parecen tener un mayor riesgo de sangrado sin una disminución de los eventos trombóticos ni la mortalidad en pacientes de UCI con COVID-19 (AU)

RESUMO

El tromboembolismo venoso (TEV), incluida la trombosis venosa profunda (TVP) y la embolia pulmonar (TEP) es una afección potencialmente letal y a tener en cuenta en mujeres embarazadas, donde la situación es favorecida por los cambios fisiológicos característicos de la gestación, el parto y el puerperio. El manejo de esta patología en este tipo de pacientes está basado en la anticoagulación, con los beneficios e inconvenientes que ello implica. Presentamos el caso de una mujer embarazada con TVP masiva e intentamos arrojar luz sobre temas como son la vía de parto (vaginal vs. cesárea) o el manejo del tratamiento (heparina de bajo peso molecular [HBPM] vs. heparina no fraccionada [HNF]) de cara a obtener la situación más segura para la paciente.(AU)


Venous thromboembolism (VTE), including deep vein thrombosis (DVT) and pulmonary embolism (PE), is a potentially lethal condition to be taken into account in pregnant women, where the situation is favored by the characteristic physiological changes of the pregnancy, childbirth and the puerperium. The management of this pathology in this type of patient is based on anticoagulation, with the benefits and drawbacks that this implies. We present the case of a pregnant woman with massive DVT and the issues are discussed, such as the method of delivery (vaginal vs. cesarean section) or the management of treatment (LMWH vs. UFH) in order to obtain the safest situation for the patient.(AU)

RESUMO

Purpose: Immune Checkpoint Inhibitors (ICI) can be associated with thrombotic events, both venous and arterial (VTE/AT). However, there is a paucity of information regarding patients in routine clinical practice.Methods/patientsRetrospective, multicenter study promoted by the Thrombosis and Cancer Section of the Spanish Society of Medical Oncology (SEOM). Patients with melanoma and lung cancer who initiated ICI between 01/01/2015 and 31/12/2019 were recruited. Minimum follow-up was 6 months (unless it was not possible because of death). The primary objective was to calculate the incidence of ICI-associated VTE/AT and the secondary objectives included to analyze its impact on survival and to identify predictor variables for VTE/AT.Results665 patients with lung cancer were enrolled. The incidence of VTE/AT during follow-up was 8.4%. Median overall survival (OS) was lower in the VTE/AT group (12 months 95% CI 4.84–19.16 vs. 19 months 95% CI 16.11–21.9; p = 0.0049). Neutrophil/lymphocyte ratio (NLR) and anemia upon initiation of IT, as well as a history of thrombosis between cancer diagnosis and the start of ICI, were predictive variables for developing of VTE/AT (p < 0.05). 291 patients with melanoma were enrolled. There was a 5.8% incidence rate of VTE/AT during follow-up. Median OS was lower in the VTE/AT group (10 months 95% CI 0.0–20.27 vs. 29 months 95% CI 19.58–36.42; p = 0.034). NLR and lactate dehydrogenase (LDH) at the beginning of ICI were predictor variables for VTE/AT (p < 0.05).ConclusionsICI increases the risk of VTE/AT in patients with lung cancer and melanoma, which impact OS.

RESUMO

Las aportaciones del Consenso Internacional sobre Tromboembolismo Venoso (ICM-VTE) modificarán nuestra práctica diaria, recogiendo la evidencia actual que no aparece en la mayoría de las guías de práctica clínica hasta la fecha. Muchos de nuestros procedimientos de cirugía ortopédica y traumatología no requieren de una profilaxis tromboembólica que solo se administra cuando existen factores de riesgos individuales o cirugías mayores (artroplastia total de miembros inferiores, cirugía de columna o fracturas que requieran inmovilización y limitación en la carga precoz). Dentro de las opciones de profilaxis debemos tener en cuenta la potencia del fármaco para prevenir el tromboembolismo venoso, pero también el efecto de hemorragia y sangrado que pueda producir. El uso de aspirina y medidas mecánicas se establece como la combinación más segura y eficaz en muchos de los casos.(AU)


The International Consensus Meeting on Venous Thromboembolism (ICM-VTE), will change our current practice as most recent evidence is included. This fact is not usual in most clinical practice guidelines to date. Many orthopedic and trauma procedures do not require thromboembolic prophylaxis, but it should be considered depending on individual risk factors or major surgeries (total hip or knee arthroplasty, spine surgery or fractures that require immobilization and weight bearing restriction). Within the prophylaxis options, we must notice the strengh of the drug preventing venous thromboembolism, but also the effect of hemorrhage and bleeding that it may produce. The use of aspirin and mechanical prophylaxis has been described as the safest and most effective combination in most cases.(AU)

RESUMO

Introducción: la trombosis de las venas hepáticas y de la vena cava inferior puede aparecer hasta en un 10 % de pacientes con tumores intrahepáticos. El fenómeno de tromboembolismo venoso por compresión maligna con o sin sobreinfección presenta mal pronóstico a corto plazo.Caso clínico:paciente de 66 años con historia de colangiocarcinoma tratado mediante resección y nuevo rescate quirúrgico años después por recaída hepática tumoral. En el posoperatorio tuvo un síndrome de Budd-Chiari y una fístula biliar, que se manejaron de forma conservadora. Posteriormente sufrió shock séptico que precisó su ingreso en la Unidad de Cuidados Intensivos. Se realizó angiotomografía computarizada que evidenció un defecto de repleción parcial de la vena cava inferior infra- y supradiafragmática. Se realizó trombectomía mecánica reolítica con dispositivo AngioJet™. Hubo resolución completa de la trombosis sin complicaciones derivadas de la intervención y con remisión tumoral a siete meses del seguimiento.Discusión:la trombectomía reolítica de la vena cava inferior puede ser una alternativa de baja invasividad y segura en pacientes con trombosis de cava de estadio IIIa.(AU)


Introduction: suprahepatic veins and inferior vena cava thrombosis can occur in up to 10 % of patients with intrahepatic tumours. The phenomenon of malignant compression venous thromboembolism with or without added superinfection has a short-term poor prognosis. although there is no gold standard in its management, it has been suggested that thrombectomy can prevent death and major complications.Case report:66-year-old patient with a history of cholangiocarcinoma, treated by resection and a new surgical rescue with chemotherapy and neoadjuvant radiotherapy due to liver tumour relapse. a postoperative complica- tion was registered, due to Budd-Chiari syndrome and a biliary fi stula that were managed conservatively. Weeks later, a septic shock was diagnosed which required admission into Intensive Care Unit. a computed tomography angiography was performed, which showed an almost complete fi lling defect of the infra and supradiaphragmatic inferior vena cava. a rheolytic mechanical thrombectomy with an AngioJet™ device was performed. Complete resolution of the thrombosis without complications derived from the intervention and with tumour remission at six months of subsequent follow-up.Discussion:rheolytic thrombectomy of the inferior vena cava can be a safe and low-invasive alternative in patients with stage IIIa thrombosis.(AU)

RESUMO

Venous thromboembolism (VTE) is a serious complication in hematologic neoplasms, so finding adequate prevention strategies is an urgent requirement. However, prospective studies with large enough cohorts are scarce, limiting the development of evidence-based thromboprophylaxis guidelines. The present position paper is addressed to all hematologists treating patients affected by hematologic neoplasms with the aim to provide clinicians with a useful tool for the prevention of VTE.

RESUMO

Introduction:D-dimer levels are elevated in COVID 19 and they correlate to the levels of other inflammatory markers such us ferritin, fibrinogen and C-reactive protein. It may be possible to correct D-dimer value in function of inflammatory markers, thus identifying patients at higher risk of venous thromboembolism (VTE). Our objectives are estimating a corrected value of plasma D-dimer as a linear function of ferritin, C-reactive protein and fibrinogen and stablishing a cut-off point of high probability of VTE.Patients and methods:Age and sex matched case-control study of all patients diagnosed with COVID 19 and VTE between March and May 2020 in a tertiary hospital in Madrid (Spain). Using linear regression, the best predictive model will be estimated and residual D-dimer values will be obtained and analyzed using ROC curves to determine its discriminative performance.Results:Thirty-eight cases and seventy-six controls were included. There was 63.2% of men and mean age was 68.2. D-dimer was best predicted by a linear model including fibrinogen, ferritin and C-reactive protein. Using residual values, the optimal cutoff point was 2165ng/mL, with a sensitivity of 57.9% and specificity of 98.7%.Conclusion:It is possible to estimate a D-dimer corrected value in function of ferritin, C-reactive protein and fibrinogen. Using the observed and estimated value we can obtain a residual value that performs well as a screening method to detect patients who would benefit for further VTE diagnostic testing.(AU)


Introducción:El dímero-D está elevado en la COVID-19 y se correlacionan con los niveles de otros marcadores inflamatorios como ferritina, fibrinógeno y proteína C reactiva. Cabe la posibilidad de corregir el dímero-D en función de dichos marcadores inflamatorios, identificando así los pacientes con mayor riesgo de enfermedad tromboembólica venosa (ETV). Nuestros objetivos son estimar un valor corregido de dímero-D como función lineal de ferritina, proteína C reactiva y fibrinógeno, y establecer un punto de corte de alta probabilidad de ETV.Pacientes y métodos:Estudio de casos y controles emparejados por sexo y edad de todos los pacientes diagnosticados con COVID-19 y ETV entre marzo y mayo de 2020 en un hospital terciario de Madrid, España. Mediante regresión lineal, se estima el mejor modelo predictivo y se obtiene el valor residual de dímero-D. Este se analizará con curvas ROC para determinar su capacidad discriminativa.Resultados:Se incluyeron 38 casos y 76 controles. Había un 63,2% de varones y la edad media fue de 68,2 años. El valor de dímero-D fue predicho por un modelo que incluyó fibrinógeno, ferritina y proteína C reactiva. Usando los valores residuales, el punto de corte óptimo estimado de 2.165ng/ml, con una sensibilidad del 57,9% y una especificidad del 98,7%.Conclusiones:Es posible estimar un valor corregido de dímero-D en función de ferritina, fibrinógeno y proteína C reactiva. Usando el valor observado y estimado podemos obtener un valor residual que funciona bien como método de cribado para detectar pacientes que podrían beneficiarse de más estudios diagnósticos de la ETV.

RESUMO

BackgroundGermline BRCA (gBRCA) mutations predispose to an increased risk of breast and ovarian cancer among other neoplasms. Recently, several genomic alterations such as ALK and ROS-1 rearrangements have been described as molecular drivers of venous thromboembolism (VTE). The association of gBRCA mutations and VTE is unknown.Materials and methodsWe performed an observational, retrospective, single-center study to determine the VTE incidence in consecutive patients with gBRCA mutations and cancer diagnosis attended in the multidisciplinary heredofamiliar cancer unit (HFCU) of Hospital General Universitario Gregorio Marañón, Spain, from 2010 to 2019.ResultsOne-hundred and forty-one patients were included in the analysis. The overall VTE incidence was 12.8%. The highest incidence was reported in ovarian cancer patients (20.0%), followed by patients with both ovarian and breast cancers (16.6%) and the lowest was found in breast cancer (4.9%). No difference in the type of gBRCA mutation (1 or 2) in terms of VTE rate was observed. Sixty one percent of the patients were receiving anti-cancer therapy at the time of VTE diagnosis and the majority of the events (83.3%) were diagnosed in ambulatory setting. Khorana score was of limited value to detect high-risk patients.ConclusionsThe VTE incidence observed in our study is consistent with prior data described in general population of breast and ovarian cancer. The risk of VTE in these patients seems to be driven by the type of cancer. We have not observed any significant interaction of gBRCA mutation status and cancer-associated thrombosis.
