ABSTRACT
In celiac disease (CD) there is a state of hypercoagulability and multiple factors have been found that may be involved. Cases of association of CD and antiphospholipid síndrome (APS) have been described and several observational studies have found an increase in antiphospolipid antibodies (AAF) in patients with CD, so both entities may be interrelated, increasing the risk of thrombotic events. A descriptive case of a patient who is simultaneusly diagnosed with CD and APS is presented.
ABSTRACT
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] 87.5100), 27.6% (95% CI 21.434.2), 51.1% (95% CI 38.263.9) and 13.4% 95% CI (6.322.7), respectively. Pooled point prevalence rates of initial arterial and venous thromboses in children and adolescents with SAPS were 45.7% (95% CI 21.171.6) and 29.2% (95% CI 14.846), 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)

INTRODUCTION: Immune thrombocytopenia (ITP) is a potentially severe manifestation of systemic lupus erythematosus (SLE) reported in 7-40% of SLE patients. ITP has been associated with a higher risk of organ damage and mortality. OBJECTIVES: To describe which factors are associated with the presence of ITP in SLE patients. METHODS: Retrospective case-control study. Cases were defined as SLE patients who had ever developed ITP and were sex- and age-matched with two controls. A predictive model was constructed to identify SLE patients who were at risk of developing ITP. RESULTS: ITP prevalence in our SLE cohort was 8.35%. Cases had a higher frequency of hemolytic anemia, while controls had a higher prevalence of arthritis at SLE diagnosis. During SLE progression, cases tested positive for anticardiolipin, anti-ß2-glycoprotein 1, and lupus anticoagulant antibodies more frequently. Cases received mycophenolic acid and azathioprine more often than controls and had a higher SLICC/ACR score. The model demonstrated a sensitivity of 87.53%, a positive predictive value of 81.92%, a specificity of 80.50%, area under the curve of 83.92%, a F1 of 83% and an overall accuracy of 83.68%. The variables that best explain the model were hemolytic anemia, arthritis, oral ulcers, Raynaud's phenomenon, low C4, low CH50, anticardiolipin and anti-ß2GP1 antibodies. CONCLUSION: SLE patients who develop ITP have a distinct phenotype characterized by more hemolytic anemia and less arthritis at SLE onset, and higher prevalence of antiphospholipid syndrome antibodies during SLE progression. This phenotype is associated with heightened organ damage and the need for more intensive therapies and stricter follow-up. Our predictive model has demonstrated an impressive ability to identify SLE patients at risk of developing ITP.

El síndrome antifosfolípido es considerado un trastorno del colágeno asociado a presentaciones clínicas a edades intermedias con incidencias no mayores de 5 casos por cada 100.000 personas. Su espectro clínico oscila en la presencia de manifestaciones trombóticas multisistémicas de origen vascular. Sin embargo, las manifestaciones no vasculares tienen un espectro raro en su presentación habitual. Se presenta el caso de un varón de 64 años con manifestaciones oculares relacionadas a amaurosis fugaz asociado a alteraciones estructurales retinianas. Los hallazgos de tamizajes realizados fueron fuertemente sugestivos de trombofilias primarias. Se aplicó perfil para síndrome antifosfolípido el cual fue positivo, por lo que se instauró anticoagulación plena.
Antiphospholipid syndrome is considered a collagen disorder associated with clinical presentations at intermediate ages with incidences of no more than 5 cases per 100,000 people. Its clinical spectrum ranges from the presence of multisystem thrombotic manifestations of vascular origin. However, non-vascular manifestations have a rare spectrum in their usual presentation. The case of a 64-year-old man with ocular manifestations related to amaurosis fugax associated with retinal structural alterations is presented. The findings of screening performed were strongly suggestive of primary thrombophilia. A profile for antiphospholipid syndrome was applied, which was positive and therefore, full anticoagulation was initiated.
ABSTRACT
ABSTRACT Objective: To understand the meanings attributed to pregnancy in the context of Lupus and antiphospholipid syndrome by women and healthcare professionals. Method: Qualitative research, using Symbolic Interactionism as a theoretical framework and Grounded Theory, a constructivist perspective. Data were collected between January and August 2022, through online interviews with 27 women with Lupus located on the social network Facebook and in-person or remote interviews with 12 healthcare professionals. Results: The theoretical model constructed has two categories: "Equal conditions, distinct experiences: experiencing the gestational process" shows that obstetric complications and lack of connection with healthcare professionals trigger negative meanings to the experience; and "Therapeutic management interfering in the attribution of meanings to the experience", demonstrates that the way women interact with healthcare professionals and how they manage treatment favors a positive reframing. Final considerations: The meanings attributed to pregnancy are elaborated and modified according to the interpretation of previous and current experiences, healthcare trajectory and interactions with healthcare professionals. Previous guidance, planning, bonding and trust in healthcare professionals enable positive meanings, while obstetric complications, unqualified assistance and lack of bonding with professionals provide negative meanings.
RESUMEN Objetivo: Comprender los significados atribuidos al embarazo en el contexto del Lupus y del síndrome antifosfolípido por mujeres y profesionales de la salud. Método: Investigación cualitativa, que utilizó como marco teórico el Interaccionismo simbólico y metodológico, la Teoría Fundamentada, una vertiente constructivista. Los datos fueron recolectados entre enero y agosto de 2022, a través de entrevistas online a 27 mujeres con Lupus ubicadas en la red social Facebook y entrevistas presenciales o remotas a 12 profesionales de la salud. Resultados: El modelo teórico construido tiene dos categorías: "Condiciones iguales, experiencias diferentes: vivir el proceso gestacional" muestra que las complicaciones obstétricas y la falta de conexión con los profesionales de la salud desencadenan significados negativos a la experiencia; y Gestión terapéutica interfiriendo en la atribución de significados", demuestra que la forma en que las mujeres interactúan con los profesionales de la salud y cómo conducen el tratamiento favorece la resignificación positiva.. Consideraciones finales: Los significados atribuidos al embarazo son elaborados y modificados según la interpretación de experiencias pasadas y actuales, trayectoria de atención e interacciones con profesionales de la salud. La orientación previa, la planificación, la vinculación y la confianza en los profesionales de la salud posibilitan significados positivos, mientras que las complicaciones obstétricas, la asistencia no calificada y la falta de vínculo con los profesionales proporcionan significados negativos.
RESUMO Objetivo: Compreender os significados atribuídos à gravidez, no contexto do Lúpus e da Síndrome Antifosfolípide, por mulheres e profissionais de saúde. Método: Pesquisa qualitativa, que utilizou como referencial teórico o Interacionismo simbólico e metodológico, a Teoria Fundamentada nos Dados, vertente construtivista. Os dados foram coletados entre janeiro e agosto de 2022, mediante entrevistas on-line com 27 mulheres com Lúpus, localizadas na rede social Facebook e em entrevistas presenciais ou remotas com 12 profissionais de saúde. Resultados: O modelo teórico construído possui duas categorias: "Condições iguais, experiências distintas: vivenciando o processo gestacional" mostra que complicações obstétricas e ausência de vínculo com os profissionais de saúde desencadeiam significados negativos à experiência; e "O manejo terapêutico interferindo na atribuição dos significados à experiência" demonstra que a forma com que a mulher interage com os profissionais de saúde e conduz o tratamento favorece a ressignificação positiva. Considerações finais: Os significados atribuídos à gestação são elaborados e modificados conforme a interpretação de experiências anteriores e atuais, trajetória assistencial e interações com os profissionais de saúde. A orientação prévia, o planejamento, o vínculo e a confiança nos profissionais de saúde possibilitam significados positivos. Já, as complicações obstétricas, a assistência não qualificada e ausência de vínculo com os profissionais produzem significados negativos.
ABSTRACT
Introducción: Los pacientes con síndrome antifosfolípido desarrollan morbilidad y mortalidad significativas a pesar del tratamiento actual. Es imperativo, identificar factores pronósticos y medidas terapéuticas para prevenir estas complicaciones. Objetivo: Determinar los factores relevantes en la predicción de la supervivencia en los pacientes con síndrome antifosfolípido. Métodos: Se realizó un estudio longitudinal analítico de una cohorte histórica de personas con síndrome antifosfolípido, diagnosticados, según los criterios de Sapporo/Sydney y colaboradores en la consulta de enfermedades autoinmunes sistémicas del Hospital Universitario Clínico-Quirúrgico «Arnaldo Milián Castro», Villa Clara, del año 2000 al 2015. Se estudiaron variables demográficas y clínicas. En cada caso se determinó el tiempo de supervivencia con relación al evento muerte. Se aplicó el método de Kaplan Meier para calcular la supervivencia global y determinar las variables predictoras de la mortalidad. Según el estudio de los estadígrafos de comparación interestratos(Log-Rank) se demostró la significación estadística con la prueba de Chi cuadrado de homogeneidad. Resultados: De los 128 pacientes estudiados, 118 fueron femeninos y 10 masculinos (111 de piel blanca y 17 no blancos). La supervivencia global fue de 67,1 % con una media de 13,37 años. Las variables más relevantes que aportaron a la mortalidad en relación con menor supervivencia fueron: leucopenia, linfopenia, color de la piel no blanca, y el no uso de aspirina, con medias de supervivencia de 8,83; 8,17; 10,72; 12,10 años, respectivamente. Conclusiones: La identificación temprana de los factores pronósticos de supervivencia permite implementar estrategias oportunas e individualizadas en pacientes con síndrome antifosfolípido.
Introduction: patients with antiphospholipid syndrome develop significant morbidity and mortality despite current treatment. Identifying prognostic factors and therapeutic measures to prevent these complications is indispensable. Objective: to determine relevant factors in the prediction of survival in patients with antiphospholipid syndrome. Methods: a longitudinal analytical study was carried out on cohorts with antiphospholipid syndrome who were diagnosed according to the Sapporo-Sydney criteria and collaborators in the systemic autoimmune disease consultation at "Arnaldo Milián Castro" Clinical and Surgical University Hospital in Villa Clara from 2000 to 2015. Demographic and clinical variables were studied. The survival time in relation to the death event was determined in each case. The Kaplan - Meier method was applied to calculate overall survival and determine the predictor variables for mortality. According to the study of inter-strata comparison statistics (Log-Rank), statistical significance was demonstrated with the Chi-square test of homogeneity. Results: a number of 118 patients were female and 10 male from the 128 studied (111 white-skinned and 17 non-white). Overall survival was 67.1% with a mean of 13.37 years. The most relevant variables that contributed to mortality in relation to lower survival were leukopenia, lymphopenia, non-white skin color and non-use of aspirin, with mean survival of 8.83; 8.17; 10.72; 12.10 years, respectively. Conclusions: the early identification of survival prognostic factors allows us the implementation of timely and individualized strategies in patients with antiphospholipid syndrome.

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.
ABSTRACT
Catastrophic antiphospholipid syndrome (CAPS) is a rare entity, approximately 600 cases have been reported around the world, and the prevalence in Mexico is unknown. OBJECTIVE: To determine the estimated prevalence of CAPS in Mexico. MATERIAL AND METHODS: A literature search of isolated clinical cases or case series was conducted in diverse search engines, using the terms: "Catastrophic Antiphospholipid Syndrome" and "Mexico" in May 2022. RESULTS: We found a series of retrospective cases in autopsies that included 12 cases, two reports that included 2 cases each, and reports of 11 isolated clinical cases; these publications were generated between 2003 and 2020. In total, we collected data on 27 cases of CAPS, of which 16 correspond to primary antiphospholipid syndrome, 10 are associated with systemic lupus erythematosus, and 1 case corresponds to systemic sclerosis. The estimated prevalence rate in the Mexican population in 2022 is 2 cases per 10,000,000 inhabitants. The estimated mortality was 68% in this case series. CONCLUSION: Cases of catastrophic antiphospholipid syndrome in Mexico are underreported; identifying them will help improve current diagnostic and therapeutic strategies used in the country, encouraging the implementation of triple therapy and, in refractory cases, the use of eculizumab, to reduce current mortality.
ABSTRACT
The objective of the systematic review is to analyze the efficacy of direct-acting oral anticoagulants (DOAC) in the prophylaxis of thrombosis in antiphospholipid syndrome (APS). We searched for clinical trials, cohort studies and meta-analyses published from January 1, 2012 to September 30, 2022. Articles that analyzed the efficacy of DOAC in the prevention of thrombosis recurrence, with or without comparison with antivitamin K (VKA) drugs, were selected. DOACs, specifically rivaroxaban and apixaban, were significantly less effective than VKAs in preventing recurrence of thrombosis in patients with APS and prior arterial thrombosis or the concomitant presence of two or three different antiphospholipid antibodies. The proportion of patients with severe bleeding as side effect are similar in those treated with DOAC and with VKA. The results argue against the use of DOAC in the treatment of patients with thrombotic APS.

BACKGROUND: There is an increasing interest in the study of non-criteria antiphospholipid antibodies (aPL) including antibodies targeting domain 1 of the B2 glycoprotein 1 (anti-D1 B2GP1) and antibodies anti phosphatidylserine/ prothrombin (PS/PT). OBJECTIVES: Our aim was to analyze a panel of conventional and non-criteria aPL in a cohort of patients with systemic lupus erythematosus (SLE) and primary antiphospholipid syndrome (APS), to describe if there are differences in aPL titers among groups, to evaluate clinical associations including risk of recurrent events of novel aPL. METHODS: Observational study that evaluated at baseline antibodies against anti-D1 B2GP1 and anti PS/PT. Anti-D1 B2GP1 antibodies were tested using a chemiluminescent immunoassay. IgG and IgM anti PS/PT, aCL and anti B2GP1 by ELISA techniques. Therefore, patients were followed in order to identify new thrombotic events. RESULTS: 133 patients with SLE and 23 with primary APS patients were included. Main APS manifestations were DVT (27%), obstetric morbidity (22%) and arterial thrombosis (10.1%). IgM anti PS/PT antibodies levels were (20.6 - 127) vs 21.9 (11.2 - 39.2) U/ml, p<0.001 in primary APS vs SLE with APS, respectively. Anti-D1 B2GP1, IgG and IgM anti PS/PT were associated with thrombotic and non-thrombotic manifestations. During follow-up, IgG B2GP1 were related with a significant cumulative risk of thrombosis. CONCLUSIONS: We found significant differences in serum titers of non-criteria aPL among patients with primary APS vs SLE with APS. Whether non-criteria aPL antibodies titers are useful to differentiate patients with primary and secondary APS requires further analysis in other populations.

Antecedentes: Hay un interés creciente en el estudio de los anticuerpos antifosfolípidos (aPL) no criterio, incluyendo anticuerpos contra el dominio 1 de la B2 glicoproteína 1 (anti-D1 B2GP1) y anticuerpos antifosfatidilserina/protrombina (PS/PT). Objetivos: Nuestro objetivo fue analizar un panel de aPL convencionales y no criterio en una cohorte de pacientes con lupus eritematoso sistémico (LES) y síndrome antifosfolípido primario (SAF), para describir si hay diferencias en los títulos de aPL entre los grupos, y evaluar asociaciones clínicas incluyendo el riesgo de eventos recurrentes con aPL novedosos. Metodología: Estudio observacional que evaluó los anticuerpos anti-D1 B2GP1 y anti-PS/PT de manera basal. Los anticuerpos anti-D1 B2GP1 se evaluaron a través de inmunoanálisis por quimioluminiscencia. Los anticuerpos anti-PS/PT, anticardiolipinas (aCL) y anti-B2GP1 fueron evaluados por técnicas de ELISA. Finalmente, los pacientes fueron seguidos en el tiempo para identificar nuevos eventos trombóticos. Resultados: Se incluyeron 133 pacientes con LES y 23 pacientes con SAF primario. Las principales manifestaciones de SAF fueron TVP (27%), morbilidad obstétrica (22%) y trombosis arterial (10,1%). Los títulos de anticuerpos anti-PS/PT IgM fueron 46,5 (20,6-127) vs. 21,9 (11,2-39,2) U/ml, p<0,001, en pacientes con SAF primario vs. LES con SAF secundario, respectivamente. Los anti-D1 B2GP1, anti-PS/PT IgG e IgM se asociaron con manifestaciones trombóticas y no trombóticas. Durante el seguimiento, los anticuerpos IgG B2GP1 se relacionaron con un riesgo acumulativo significativo de trombosis. Conclusiones: Se encontraron diferencias estadísticamente significativas en títulos séricos de aPL no criterio en pacientes con SAF primario vs. pacientes con LES y SAF secundario. Si los títulos de aPL no criterio son útiles para diferenciar entre SAF primario y SAF secundario, se requieren más análisis en otras poblaciones para poder confirmar si los títulos de aPL no criterio.

Las hemorragias y la enfermedad tromboembólica venosa (ETEV) figuran entre las cinco causas más frecuentes de morbilidad y mortalidad materna en el mundo. Revisamos la evaluación y el manejo actualizado de las causas obstétricas de la hemorragia posparto (HPP), así como el diagnóstico y manejo de condiciones hematológicas que pueden causar o agravar la HPP, por ejemplo: coagulación intravascular diseminada, enfermedad de von Willebrand, trombocitopenia autoinmune y las microangiopatías trombóticas. Revisamos el rol del síndrome antifosfolípido y las trombofilias hereditarias como factores predisponentes a pérdidas fetales recurrentes y la ETEV en el embarazo y las recomendaciones actuales para la prevención de ambas complicaciones. Asimismo, repasamos el abordaje diagnóstico y líneas de manejo de la ETEV. Un objetivo adicional fue enfatizar la importancia del trabajo colaborativo multidisciplinario para lograr el manejo exitoso de las gestantes con las complicaciones obstétricas y hematológicas descritas.
Bleeding and venous thromboembolism (VTE) are among the five most common causes of morbidity and mortality in pregnant women worldwide. This review describes the current evaluation and management of the obstetric causes of postpartum hemorrhage (PPH), as well as the diagnosis and management of hematologic conditions which can cause or worsen PPH, such as disseminated intravascular coagulation, von Willebrand disease, autoimmune thrombocytopenia and the thrombotic microangiopathies. It also describes the role of the antiphospholipid syndrome and inherited thrombophilia as predisposing factors for recurrent pregnancy loses and VTE, and the current recommendations for the prevention of both complications. As well, the current diagnostic approach and management of ETEV are described. An additional objective of this Review is to emphasize the importance of a collaborative multidisciplinary approach for the successful management of the obstetric and hematologic complications herein described.
ABSTRACT
Presentamos el caso de una paciente mujer de 31 años con antecedente de litiasis coraliforme bilateral. Ella inició la enfermedad un mes antes del ingreso con trombocitopenia y anemia hemolítica autoinmune. Fue diagnosticada con Síndrome de Evans, inicialmente tuvo marcadores de autoinmunidad negativos, finalmente presentó disnea progresiva y se le encontró 4 masas intracardiacas en aurícula derecha y marcadores positivos para síndrome antifosfolípido. A pesar de la anticoagulación y preparación para cirugía cardiaca, la paciente tuvo una muerte súbita.
We present the case of a 31-year-old female patient with a history of bilateral staghorn lithiasis, who started the disease one month before admission with thrombocytopenia and autoimmune hemolytic anemia. She was diagnosed with Evans Syndrome, initially she had negative autoimmunity markers, finally presented progressive dyspnea and 4 intracardiac masses were found in the right atrium and positive markers for antiphospholipid syndrome. Despite anticoagulation and preparation for cardiac surgery, she presented sudden death.
ABSTRACT
Background and objectives Retinal vein occlusion (RVO) is the second most frequent cause of retinal vascular disease and is related to classic cardiovascular risk factors. A specific program was designed to detect and treat risk factors in patients with RVO. The aim of this study is to audit the results of this program. Patients and methods The program consisted of a multidisciplinary clinical evaluation by the Ophthalmology and Internal Medicine Departments. All patients with RVO were screened, at minimum, for hypertension, diabetes, dyslipidemia, smoking, overweight, and antiphospholipid syndrome. New risk factors or poor control of known risk factors were expected to be found in at least one-third of the patients. Among them, therapeutic measures were expected to be taken in at least two-thirds. A dissociated automated search of the data of all patients who entered the program between April 2021 and April 2022 was performed. Results Fifty-six patients were included for analysis. Of these, 39 (69.6%) had at least one new or poorly controlled risk factor and 43 (76.8%) had their treatment modified in some way. Antiphospholipid syndrome was detected in five (8.9%). Only one patient had low-risk hereditary thrombophilia. After an exhaustive examination, no risk factors were found in 11 patients. Conclusion This specific program has been effective in detecting new or poorly controlled risk factors and improving their treatment (AU)
Antecedentes y objetivo La trombosis venosa de retina (TVR) es la segunda causa más frecuente de enfermedad vascular de la retina y se relaciona con factores de riesgo cardiovascular clásicos. Se diseñó un programa específico para detección y tratamiento de factores de riesgo en pacientes con TVR. El objetivo de este estudio es auditar los resultados de dicho programa. Pacientes y métodos El programa consistió en una evaluación clínica multidisciplinar por parte de Oftalmología y Medicina Interna. A todos los pacientes con TVR se les realizó cribado, al menos, de hipertensión arterial, diabetes, dislipidemia, tabaquismo, sobrepeso y síndrome antifosfolípido. Se esperó encontrar nuevos factores de riesgo o pobre control de los ya conocidos en, al menos, un tercio de los pacientes. Entre ellos, se esperó tomar alguna medida terapéutica en, al menos, dos tercios. Se llevó a cabo una búsqueda automatizada disociada de los datos de todos los pacientes que entraron en el programa entre abril de 2021 y abril de 2022. Resultados Cincuenta y seis pacientes se incluyeron para el análisis. De ellos, 39 (69,6%) tenían al menos un factor de riesgo nuevo o mal controlado, y 43 (76,8%) vieron modificado en algún modo su tratamiento. Se detectó síndrome antifosfolípido en 5 (8,9%). Solo un paciente tenía una trombofilia hereditaria de bajo riesgo. Tras un examen exhaustivo no se encontró factor de riesgo alguno en 11 pacientes. Conclusión Este programa específico ha sido efectivo para detectar factores de riesgo nuevos o mal controlados y mejorar su tratamiento (AU)

Only one patient had low-risk hereditary thrombophilia. After an exhaustive examination, no risk factors were found in 11 patients. CONCLUSION: This specific program has been effective in detecting new or poorly controlled risk factors and improving their treatment.

Introducción: El síndrome antifosfolipídico (SAF) es una afección de origen autoinmune caracterizada por trombosis, pérdidas fetales recurrentes y anticuerpos antifosfolipídicos (aFL). Existen manifestaciones clínicas no contempladas en los criterios clasificatorios, que se denominan manifestaciones no criterio. Objetivo: Analizar las manifestaciones clínicas del SAF, enfatizando las manifestaciones no criterio y su relación con el perfil de autoanticuerpos en un hospital general de Montevideo, Uruguay. Métodos: Se realizó un estudio retrospectivo de las historias clínicas de pacientes con diagnóstico definitivo o sospecha de SAF en un servicio de medicina ambulatoria de enfermedades autoinmunes, en el Hospital Maciel, asistidos entre el 2010 y 2019. Resultados: Se incluyeron 78 pacientes, con edad media de 50,3 ± 14,5 años, 69 (88,5%) correspondió a sexo femenino. Cuarenta y seis (59,0%) pacientes presentaron SAF secundario, de los cuales 28 (35,9%) asociaron LES. La trombosis venosa de miembros inferiores fue la manifestación más frecuente (51,3%). Dieciocho (24,0%) pacientes presentaron trombosis arteriales en forma de accidente cerebrovascular. Cincuenta y nueve (75.6%) casos presentaron, además de las manifestaciones clasificatorias, alguna de las manifestaciones "no criterio" y éstas se manifestaron de forma aislada en 10 (12.8%) pacientes. Las manifestaciones no clasificatorias más frecuentes fueron artralgias, livedo reticularis, migraña y trombocitopenia. Se observó una asociación significativa entre la presencia de anti-ß2GPI con manifestaciones cutáneas y de trombocitopenia con al menos una manifestación trombótica. Conclusiones: Las manifestaciones "no criterio" del SAF se presentaron en casi 3 de cada 4 casos, frecuencia similar a la observada en otras series. La presencia aislada de manifestaciones "no criterio" podrían hacer sospechar un SAF y en algunos casos, conducir a la solicitud de anticuerpos.
Introduction: Antiphospholipid syndrome (APS) is an autoimmune condition characterized by thrombosis, recurrent fetal loss, and antiphospholipid antibodies. There are clinical manifestations not contemplated in the classification criteria, which are called non-criterion manifestations. Objective: To analyze the clinical manifestations of APS, emphasizing the non-criterion manifestations and their relationship with the autoantibody profile in a general hospital in Montevideo, Uruguay. Methods: A retrospective analysis of the medical records of patients with a definitive or suspected diagnosis of APS in an outpatient medicine service for autoimmune diseases, at the Maciel Hospital, assisted between 2010 and 2019, was carried out. Results: 78 patients were included, with a mean age of 50.3 +/- 14.5 years, 69 (88.5%) were female. Forty-six (59.0%) patients presented secondary APS, of which 28 (35.9%) associated SLE. Venous thrombosis of the lower limbs was the most frequent manifestation (51.3%). Eighteen (24.0%) patients presented arterial thrombosis in the form of cerebrovascular accident. Fifty-nine (75.6%) cases presented, in addition to the classification manifestations, some of the "non-criterion" manifestations and these manifested in an isolated way in 10 (12.8%) patients. The most frequent non-classifying manifestations were arthralgia, livedo reticularis, migraine and thrombocytopenia. A significant association was observed between the presence of anti-ß2GPI with cutaneous manifestations and thrombocytopenia with at least one thrombotic manifestation. Conclusions: Non-criterion manifestations of APS occurred in almost 3 out of 4 cases, a frequency similar to that observed in other series. The isolated presence of "non-criterion" manifestations could lead to suspicion of APS and, in some cases, lead to the request for antibodies.
Introdução: A síndrome antifosfolipídica (SAF) é uma doença de origem auto-imune caracterizada por trombose, perdas fetais recorrentes e anticorpos antifosfolípidos (aFL). Existem manifestações clínicas não abrangidas pelos critérios de classificação, que são designadas por manifestações não-critério. Objetivo: Analisar as manifestações clínicas da SAF, enfatizando as manifestações não-critério e sua relação com o perfil de auto-anticorpos em um hospital geral de Montevidéu, Uruguai. Métodos: Foi realizado um estudo retrospectivo dos prontuários de pacientes com diagnóstico definitivo ou suspeita de SAF em um serviço ambulatorial de doenças autoimunes do Hospital Maciel, atendidos entre 2010 e 2019. Resultados: Foram incluídos 78 pacientes, com idade média de 50,3 +/- 14,5 anos, sendo 69 (88,5%) do sexo feminino. Quarenta e seis (59,0%) pacientes apresentavam PFS secundária, dos quais 28 (35,9%) tinham LES associado. A trombose venosa dos membros inferiores foi a manifestação mais frequente (51,3%). Dezoito (24,0%) doentes apresentaram trombose arterial sob a forma de acidente vascular cerebral. Cinquenta e nove (75,6%) casos apresentaram, para além das manifestações classificatórias, algumas das manifestações "não-critério" e estas manifestações foram isoladas em 10 (12,8%) doentes. As manifestações não classificatórias mais frequentes foram artralgias, livedo reticularis, enxaqueca e trombocitopenia. Foi observada uma associação significativa entre a presença de anti-ß2GPI com manifestações cutâneas e trombocitopenia com pelo menos uma manifestação trombótica. Conclusões: As manifestações "não-critério" de SAF ocorreram em quase 3 de cada 4 casos, frequência semelhante à observada noutras séries. A presença isolada de manifestações "não-critério" pode levantar a suspeita de SAF e, nalguns casos, levar à pesquisa de anticorpos.
ABSTRACT
El síndrome antifosfolípido (SAF) es una entidad caracterizada por fenómenos trombóticos (arteriales y/o venosos), pérdidas fetales y elevación sérica persistente de anticuerpos antifosfolípidos. Las complicaciones pulmonares más frecuentes del SAF son: tromboembolismo pulmonar, hipertensión pulmonar tromboembólica. La hemorragia alveolar es una manifestación infrecuente y potencialmente mortal (SAF catastrófico). El diagnóstico se confirma cuando en una muestra tomada mediante lavado bronquioalveolar (BAL), más del 20 % de los macrófagos son positivos para hemosiderina. Los hallazgos radiográficos más comúnmente muestran opacidades en vidrio deslustrado o de consolidación que suelen ser difusas, bilaterales más centrales que periféricas. La DLCO es otro método diagnóstico, con valores por encima del 120 % del valor predicho. Presentamos el caso de un paciente con SAF con antecedentes de trombosis venosa profunda (TVP) y tromboembolismo pulmonar (TEP) anticoagulado, que ingresa con diagnóstico de hemorragia alveolar (HA).
Antiphospholipid syndrome (APS) is an entity characterized by thrombotic phenomena (arterial and/or venous), fetal losses, and persistent increase in the serum level of antiphospholipid antibodies. The most common pulmonary complications of APS are pulmonary thromboembolism and thromboembolic pulmonary hypertension. Alveolar hemorrhage is a rare, potentially life-threatening manifestation (catastrophic APS). The diagnosis is confirmed when more than 20 % of the macrophages in a sample taken by bronchoalveolar lavage (BAL) are positive for hemosiderin. Radiographic findings most commonly show ground-glass opacities or consolidations that are usually diffuse, bilateral, more central than peripheral. The DLCO is another diagnostic method, with values above 120 % of the predicted value. We present the case of a patient with APS with a history of deep vein thrombosis (DVT) and anticoagulated pulmonary thromboembolism (PTE), who was admitted with a diag nosis of alveolar hemorrhage (AH).

MaleABSTRACT
El embarazo constituye un factor de riesgo independiente de eventos tromboembólicos, provocado por los cambios en la hemostasia que se producen durante la gestación. Las trombofilias son trastornos de la hemostasia que predisponen a eventos trombóticos. La creciente evidencia sugiere que las trombofilias se asocian a enfermedad tromboembólica y resultados obstétricos desfavorables. Sin embargo, las limitaciones metodológicas han dificultado la obtención de una visión general clara de los riesgos que suponen durante la gestación. El objetivo del presente artículo es realizar una revisión bibliográfica exhaustiva sobre el uso de tromboprofilaxis durante la gestación, con especial interés en esclarecer qué trombofilias tienen indicación de anticoagulación durante el embarazo basada en una mejora de los resultados obstétricos demostrados en la literatura científica.(AU)
Pregnancy is an independent risk factor for thromboembolic events, caused by changes in haemostasis that occur during pregnancy. Thrombophilia comprises disorders of haemostasis that predispose to thrombotic events. Increasing evidence suggests that thrombophilia is associated with thromboembolic disease and poor obstetric outcomes. However, methodological limitations have made it difficult to obtain a clear overview of the risk they pose during pregnancy. The objective of this article is to carry out an exhaustive bibliographic review on the use of thromboprophylaxis during pregnancy, with special interest in clarifying the thrombophilia for which anticoagulation is indicated during pregnancy based on an improvement in obstetric results demonstrated in the scientific literature.(AU)

El síndrome de Budd-Chiari es causado por una obstrucción del flujo sanguíneo del hígado. Los casos publicados del síndrome antifosfolípido asociado a SBC son limitados en la población pediátrica. Reportamos el caso de una adolescente de 15 años que presentó fiebre, ascitis y hepatoesplenomegalia. En la ecografía Doppler hepática se observó ausencia de flujo en la vena hepática derecha y media, y en la vena cava inferior. En la tomografía abdominal se observó una extensa trombosis de la vena cava inferior. Durante la hospitalización se le diagnosticó SAF y lupus eritematoso sistémico. Se le administró tratamiento con heparina no fraccionada, heparina de bajo peso molecular y anticoagulantes. El síndrome de Budd-Chiari secundario al síndrome antifosfolípido es una enfermedad potencialmente mortal. El diagnóstico y el tratamiento oportunos permiten mejorar la calidad de vida del paciente.
Budd-Chiari syndrome is caused by an obstruction of blood flow to the liver. Published cases of the antiphospholipid syndrome associated with BCS are limited in the pediatric population. We report a 15-year-old adolescent who presented with fever, ascites, and hepatosplenomegaly. Hepatic Doppler ultrasound revealed no flow in the right and middle hepatic veins and in the inferior vena cava. Abdominal tomography revealed extensive thrombosis of the inferior vena cava. During hospitalization, she was diagnosed with antiphospholipid syndrome and systemic lupus erythematosus. She was given treatment with unfractionated heparin, low molecular weight heparin, and anticoagulants. Budd-Chiari syndrome secondary to the antiphospholipid syndrome is a life-threatening disease. Timely diagnosis and treatment improve the quality of life of the patient.
