ABSTRACT
Objetivo: Describir las características demográficas y trastornos de pacientes con diagnóstico de síndrome de activación macrofágica (SAM) en el periodo comprendido entre diciembre de 2008-enero de 2014. Métodos: Se revisaron las historias clínicas desde el diagnóstico de SAM y tras su alta hospitalaria hasta enero de 2014. Los pacientes se agruparon en 4 grupos: autoinmunes (AI), hemato-oncólogicas (HO), infecciosas (Inf) y oncológicas (Onc). Las variables fueron analizadas entre los 4 grupos y entre AI y HO. Resultados: Trece pacientes (7 hombres, con una mediana de 54 años [32-63]) se estudiaron. Las etiologías encontradas fueron: 5 AI, 5 HO, 2 Inf y una Onc. Se encontraron células hemofagocíticas en el líquido ascítico en uno de los pacientes. Se encontró un paciente con SAM secundario a enfermedad relacionada con la IgG4. Conclusiones: La mortalidad, el pronóstico y la evolución de la enfermedad puede verse influida por el retraso en el diagnóstico, el inicio del tratamiento y la etiología del SAM. Los pacientes con enfermedades HO presentaron peor pronóstico (AU)
Objective: Describe the demographic characteristics and disorders of patients with diagnosis of Macrophage Activation Syndrome (MAS) in the December 2008 - January 2014 period. Methods: Medical records were reviewed from diagnosis of MAS and after discharge until January 2014. Patients were divided into 4 groups according to the primary disease: Autoimmune (AI), Hemato - oncologic (HO), Infectious (Inf) and Oncologic (Onc). The variables were analyzed among the 4 groups and between AI and HO. Results: Thirteen patients [7 men, with a median of 54 years (32-63)] were studied. The etiologies were: 5 AI, 5 HO, 2 Inf. and 1 Onc. disease. Hemophagocitc cells were found in the ascitic fluid of one patient. A patient with MAS secondary to IgG4-related disease was found. Conclusions: Mortality, prognosis and disease progression may be influenced by the delay in diagnosis, treatment initiation and etiology of MAS. HO ill patients had a worse prognosis (AU)

Introducción. El síndrome hemofagocítico (SH) se produce en enfermedades autoinmunes y pertenece al grupo de enfermedades linfohistiocitosis hemofagocítica. El presente trabajo describe las características de 2 pacientes con lupus eritematoso sistemico (LES) que comenzaron con SH. Observaciones clínicas. Ambos pacientes presentaron fiebre prolongada no asociada a proceso infeccioso y que no respondía a antibióticos. Discusión. El diagnóstico de SH secundario a LES es complicado, ya que presentan características comunes; sin embargo, el SH presenta hiperferritinemia, hipofibrinogenemia, hipertrigliceridemia y descenso de la velocidad de sedimentación globular a diferencia del LES. El tratamiento no está bien establecido, pero los corticoides y/o inmunoglobulinas son efectivos en el tratamiento inicial, y en casos refractarios la ciclosporina o la ciclofosfamida se pueden asociar. Conclusiones. El SH puede ser la manifestación inicial del LES y debe sospecharse en pacientes con organomegalias, citopenias, trastornos en la coagulación, alteraciones hepáticas y fiebre prolongada que no responde a antibióticos. Anakinra puede ser una opción de tratamiento en el SH secundario al LES adulto (AU)
Introduction: Hemophagocytic syndrome (HS) occurs in autoimmune diseases and belongs o the hemophagocytic lymphohistiocytosis group of diseases. This paper describes the features of 2 patients with systemic lupus erythematosus (SLE) who presented HS as the initial clinical manifestation. Clinical observations: Both patients had prolonged fever not associated to an infectious process and did not respond to broad-spectrum antibiotics. Discussion: The diagnosis of HS secondary to SLE is complicated, because it has some features in common, but HS is characterized by hyperferritinemia, hipofibrinogemia, hypertriglyceridemia and a decrease in the erythrocyte sedimentation rate, unlike SLE. HS treatment when associated to SLE is not well established, but steroids and/or immunoglobulins are effective as the initial treatment, and in refractory cases, cyclosporine or cyclophosphamide may be associated. Conclusions: HS can be the initial manifestation of SLE and should be suspected in patients with organ enlargement, cytopenias, clotting disorders, liver disorders and prolonged fever unresponsive to antibiotics. Anakinra may be a treatment option in adult HS associated to SLE (AU)
