Noninfectious aortitis: Experience with tocilizumab in a regional hospital. / Aortitis no infecciosa: experiencia con tocilizumab en un hospital comarcal.

OBJECTIVES: Describe patients with noninfectious aortitis and their response to treatment in a regional hospital. METHODS: Review of patients with noninfectious aortitis, diagnostic technique used and immunosuppressive therapy received. RESULTS: We report 8 patients (7 women and one man) diagnosed with aortitis by positron emission tomography (PET). The mean age was 69years (interquartile range [IQR] 62-72.2). Three months of treatment with tocilizumab improved symptoms, erythrocyte sedimentation rate and C-reactive protein level (P<.001 and P<.012, respectively) in the 6 patients in whom it was used. CONCLUSIONS: Tocilizumab was an effective and safe treatment in those patients diagnosed with aortitis refractory to steroids and conventional immunosuppressive therapy.

Secondary macrophage activation syndrome due to autoimmune, hematologic, infectious and oncologic diseases. Thirteen case series and review of the literature.

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.

Hemophagocytic syndrome as the initial manifestation of systemic lupus erythematosus.

INTRODUCTION: Hemophagocytic syndrome (HS) occurs in autoimmune diseases and belongs to 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.
