Catastrophic antiphospholipid syndrome / Síndrome antifosfolípido catastrófico

ABSTRACT The antiphospholipid syndrome (APS) is a systemic autoimmune disease characterized by the development of thrombotic events and/or obstetric morbidity in the presence of antiphospholipid antibodies (aPL), such as the lupus anticoagulant (LA), anticardiolipin antibodies (aCL) or anti- β 2-glycoprotein I antibodies (a β2 GPI). In 1992, Ronald A. Asherson described a very aggressive clinical variant of this syndrome characterized by the development of multiple thrombotic manifestations, simultaneously or in a short period of time. The term catastrophic APS was proposed and since then it is known by this name.

RESUMEN El síndrome antifosfolípido (SAF) es una enfermedad sistêmica autoinmune, caracterizada por el desarrollo de eventos trombóticos y/o morbilidad obstétrica en presencia de anticuerpos antifosfolípidos (aPL), tales como el anticoagulante lúpico (AL), los anticuerpos anticardiolipina (aCL) o anticuerpos anti- β2-glicoproteína I (aβ2GPI). En 1992, Ronald A. Asherson describió una variante clínica muy agresiva de este síndrome, caracterizada por el desarrollo de múltiples manifestaciones trombóticas, de manera simultánea o dentro de un corto periodo de tiempo. Se propuso entonces el término SAF catastrófico y desde entonces se le ha conocido por ese nombre.

Síndrome antifosfolípido catastrófico "seronegativo" en pediatría: caso clínico / "Seronegative" catastrophic antiphospholipid syndrome in pediatrics: clinical case

INTRODUCCIÓN: El síndrome antifosfolípido es una trombofilia adquirida autoinmune, caracterizada por trombosis arteriales y/o venosas. En raras ocasiones este cuadro puede tener una presentación catastrófica, de elevada mortalidad, con presencia de microangiopatia y compromiso de tres o más órganos. OBJETIVO: Describir la presentación clínica y evolución de una paciente pediátrica con síndrome antifosfolípido catastrófico, con forma de inicio seronegativa, cuya respuesta a terapia agresiva fue favorable. CASO CLÍNICO: Paciente femenina adolescente, que debutó cuadro de una semana de evolución de dolor, incremento del volumen abdominal y edema en extremidades inferiores. Se diagnosticó lupus eritematoso generalizado y se descartó proceso neoplásico. Durante su evolución pre sentó diversos eventos trómboticos, al inicio con presencia de anticuerpos antifosfolípido negativos, que posteriormente fueron positivos. Cursó con deterioro multisistémico secundario a trombosis multiorgánica, requirió soporte hemodinámico y ventilatorio. Se manejó con heparina de bajo peso molecular, plasmaféresis, anticoagulación, inmunosupresión y bolos de rituximab con excelente respuesta. CONCLUSIONES: Consideramos este caso de interés por tratarse de un diagnóstico infrecuente en la edad pediátrica y cuya sospecha, manejo intensivo y oportuno, puede cambiar el pronóstico sombrío y de alta mortalidad de estos pacientes.

INTRODUCTION: The antiphospholipid syndrome is an acquired autoimmune thrombophilia, characterized by arterial and/or venous thrombosis. Rarely, this condition can have a catastrophic presenta tion, with high mortality, and presence of microangiopathy and involvement of three or more organs. OBJECTIVE: To describe the clinical presentation and evolution of a pediatric patient with catastrophic antiphospholipid syndrome, with a seronegative onset form, whose response to aggressive therapy was favorable. CLINICAL CASE: Adolescent female, with a one-week history of pain, increased abdo minal volume and edema in the lower extremities. Generalized lupus erythematosus was diagnosed and the neoplastic process was ruled out. During its evolution, she presented various thrombotic events, initially with the presence of negative antiphospholipid antibodies, which were subsequently positive. The patient presented multisystemic failure secondary to multiorgan thrombosis, required hemodynamic and ventilatory support. It was managed with low molecular weight heparin, plas mapheresis, anticoagulation, immunosuppression and boluses of rituximab with excellent response. CONCLUSIONS: We consider this case interesting because it is an infrequent diagnosis in the pediatric age and whose suspicion, timely and aggressive intensive management, can change the poor progno sis and high mortality of these patients.

Therapeutic plasma exchange in rheumatic diseases: a university hospital experience / Troca plasmática terapêutica em doenças reumáticas: a experiência de um hospital universitário

Abstract Introduction: Each day, evidence accumulates related to the use of therapeutic plasma exchange (TPE) in patients with rheumatic diseases. San Ignacio University Hospital has recorded all of the TPE sessions performed by the institution's apheresis group. Objective: To describe the TPE experience of patients with rheumatologic diseases in a hospital setting. Methods: Descriptive, observational, retrospective analysis. This study included analyses of the TPE sessions that were performed in patients with rheumatic diseases from November 2009 to November 2013. Results: The apheresis group performed 136 sessions in 27 patients. The mean patient age was 43 years (SD 18.5), and 59.3% of the patients were female. Regarding the diagnosis, the most frequents ones where: ANCA-associated vasculitis followed by systemic lupus erythematosus and catastrophic antiphospholipid syndrome. The average number of sessions per patient was 5 (SD 1.8), and the average plasma exchange per patient was 1.3 plasma volume replacement units. The most used replacement solution was frozen fresh plasma (FFP; 63.2% of the sessions). Of all the sessions, 4.4% presented complications, and the majority of the complications were related to vascular access. Fifteen patients required renal replacement therapy (RRT) secondary to the same cause that created the need for TPE, 3 patients required RRT due to causes other than the TPE diagnostic intervention and 1 patient had undergone chronic dialysis. Conclusions: TPE is a therapeutic alternative that is needed for the management of patients with rheumatic diseases with renal involvement and those who are refractory to conventional management. Our clinical results were in agreement with the global literature.

Resumo Introdução: Diariamente acumulam-se evidências relacionadas com o uso da troca plasmática terapêutica (TPT) em pacientes com doenças reumáticas. O Hospital Universitário San Ignacio registrou todas as sessões de TPT feitas pelo grupo de aférese dessa instituição. Objetivo: Descrever a experiência do Hospital Universitário San Ignacio na TPT em pacientes com doenças reumatológicas. Métodos: Análise observacional, retrospectiva, descritiva. Incluiu análises das sessões de TPT feitas em pacientes com doenças reumáticas de novembro de 2009 a novembro de 2013. Resultados: O grupo de aférese fez 136 sessões em 27 pacientes. A idade média foi de 43 anos (DP 18,5) e 59,3% eram do sexo feminino. Quanto ao diagnóstico, os mais frequentes foram: vasculite associada ao anticorpo anticitoplasma de neutrófilos (ANCA) seguida de lúpus eritematoso sistêmico e síndrome antifosfolipídica catastrófica. A quantidade média de sessões por paciente foi de cinco (DP 1,8) e a média de troca plasmática por paciente foi de 1,3 unidade de substituição do volume de plasma. A solução de substituição mais usada foi o plasma fresco congelado (PFC, 63,2% das sessões). De todas as sessões, 4,4% apresentaram complicações, a maioria delas relacionadas com o acesso vascular. Quinze pacientes necessitaram de terapia de substituição renal (TSR) secundária à mesma causa que levou à necessidade de TPT; três pacientes necessitaram de TSR em decorrência de outras causas além da intervenção diagnóstica de TPT e um paciente tinha sido submetido à diálise crônica. Conclusões: A TPT é uma opção terapêutica necessária para o manejo de pacientes com doenças reumáticas com envolvimento renal e daqueles que são refratários ao tratamento convencional. Os resultados clínicos do presente estudo estão de acordo com o que é encontrado na literatura global.

Síndrome antifosfolípido catastrófico: caso clínico / Catastrophic antiphospholipid syndrome: clinical case

El síndrome antifosfolípido (SAF) fue descrito y caracterizado durante la segunda mi-tad del siglo XX inicialmente como un fenómeno protrombótico secundario en con-texto de otras enfermedades del tejido conectivo, principalmente lupus. Sin embargo, el estudio de pacientes con enfermedad primaria impulsó a distintos consensos, tan-to clínicos como de laboratorio para su correcta identificación. Entre los pacientes con SAF destaca la forma de presentación catastrófica, de baja prevalencia, pero impor-tante por su mal pronóstico, caracterizada por el compromiso de múltiples sistemas en corto tiempo. Presentamos el caso de una paciente del Hospital Clínico San Borja-Arriarán con diag-nóstico de SAF primario, que presentó en su evolución la forma catastrófica. Este caso sirve de base para una revisión del proceso diagnóstico del SAF en relación a otras patologías reumatológicas y las características propias del SAF catastrófico.

Antiphospholipid syndrome (APS) was described and characterized during the second half of the 20th century initially as a secondary prothrombotic phenome-non in the context of other connective tissue diseases, mainly lupus. However, the study of patients with primary disease prompted different consensus, both clin-ical and laboratory for their correct identification. Among patients with APS, the catastrophic presentation is of low prevalence, but important because of its poor prognosis, characterized by the commitment of multiple systems in a short time. We present the case of a patient from the San Borja-Arriaran Clinic Hospital with di-agnosis of primary APS, which presented the catastrophic form in its evolution. This case serves as a basis for a review of the diagnostic process of APS in relation to other rheumatologic pathologies and the characteristics of catastrophic APS.

Síndrome antifosfolípido catastrófico / Catastrophic antiphospholipid syndrome

El síndrome antifosfolípido está definido por la combinación de manifestaciones clínicas trombóticas y/u obstétricas y un título persistentemente alto y significativo de anticuerpos antifosfolípidos. La presencia de múltiples trombos en lechos vasculares pequeños que lleva a falla multiorgánica, simultáneamente o en menos de 1 semana, define al síndrome antifosfolípido catastrófico el cual conlleva alta mortalidad; sin embargo, la sospecha diagnóstica y la institución temprana del tratamiento, definitivamente inciden en el pronóstico de éstos pacientes(AU)

Antiphospholipid syndrome is defined by the combination of thrombotic and/or obstetric clinical manifestations and a persistently high and significant title of antiphospholipid antibodies. The presence of multiple thrombi in small vascular beds leading to multi-organ failure that occurs simultaneously or in less than 1 week, and defines the catastrophic antiphospholipid syndrome which carries high mortality, The suspected diagnosis and early treatment affects the prognosis of these patients(AU)

Catastrophic antiphospholipid syndrome – A case report.

Catastrophic antiphospholipid syndrome (CAPS) is a rare, potentially life-threatening condition, acute in onset , characterized by diffuse vascular thrombosis, leading to multiple organ failure in a short period of time in the presence of positive antiphospholipid antibodies (aPL). Lupus anticoagulant and anticardiolipin antibodies are the predominant antibodies associated with CAPS. Treatment options for CAPS include anticoagulation, steroids, plasma exchange, cyclophosphamide therapy, and intravenous immunoglobulin therapy. The high rate of mortality warrants greater awareness among clinicians for early diagnosis and treatment of CAPS. In this case report, 30-yearold post-partum female presented with progressive weakness, shortness of breath of grade IV and swelling of all the four limbs of 15 days duration with an episode of seizure. Investigations revealed MRV - cortical sinus venous thrombosis (CSVT) of transverse and sigmoid sinus, Raised anti-ds DNA anticardiolipin and lupus anticoagulant, 24 hour urinary proteins – 540 mg/day indicating clinical lupus nephritis. Weakness of all the limbs with areflexia indicated acute inflammatory demyelinating polyneuropathy (AIDP). 2D echocardiography- post partum dilated cardiomyopathy (DCMP).

Hepatic infarction in a pregnant woman with antiphospholipid syndrome and triple antibody positivity: A case report focusing on catastrophic antiphospholipid syndrome

Pregnant women with antiphospholipid syndrome (APS) carry a high risk of arterial or venous thrombosis. Such thrombotic conditions occur more frequently in patients with triple positivity to antiphospholipid antibodies or with high antibody titers. Hepatic infarction is a rare complication in pregnant women with APS, and it sometimes mimics HELLP syndrome. This report describes a preeclamptic pregnant woman with APS who had high titers of three antiphospholipid antibodies. She experienced severe epigastric pain with elevated liver enzymes; in addition, she had tachycardia and tachypnea. The clinical findings suggested hepatic infarction and pulmonary thromboembolism, a partial manifestation of catastrophic APS. Therefore, she underwent emergent cesarean section at 25+2 weeks of gestation. After the delivery, her laboratory test indicated HELLP-like features, and computed tomography confirmed hepatic infarction and pulmonary micro-thromboembolism. Here, we report a case of a partial manifestation of catastrophic APS in a pregnant woman with triple antibody positivity, including a brief literature review.

A Case of Catastrophic Primary Antiphospholipid Syndrome / 대한내과학회지

Catastrophic antiphospholipid syndrome is a rare clinical syndrome characterized by acute multi-organ failure occurring in patients with antiphospholipid antibodies. It is associated with involvement of several end-organs particularly kidneys, lungs, gastrointestinal tracts and adrenal glands and presents catastrophic clinical pictures such as acute renal failure with thrombotic microangiopathy, myocardial failure, adult respiratory distress syndrome, convulsion and disseminated intravascular coagulation. Conventional treatments(e.g. intravenous heparin, steroid, immunosuppressants) were not effective, while plasmapheresis seems to be a useful therapy. We experienced a case of catastrophic primary antiphospholipid syndrome in 41-year-old woman proved by renal biopsy and immuno-serological tests. She developed acute renal failure, multiple esophageal and oral ulcers, adult respiratory distress syndrome, abnormal elevation of hepatic and pancreatic enzymes and signs of disseminated intravascular coagulation. Evidences of any other connective tissue diseases were not found. Renal biopsy revealed features of thrombotic microangiopathic nephropathy and serum antiphospholipid antibody level was elevated(34GPL). In spite of steroid, cyclophosphamide and supportive therapies, her respiratory distress was not improved.
