Development and initial validation of the macrophage activation syndrome/primary hemophagocytic lymphohistiocytosis score, a diagnostic tool that dif…
2017
OBJECTIVE: To develop and validate a diagnostic score that assists in discriminating primary hemophagocytic lymphohistiocytosis (pHLH) from macrophage activation syndrome (MAS) related to systemic juvenile idiopathic arthritis. STUDY DESIGN: The clinical, laboratory, and histopathologic features of 362 patients with MAS and 258 patients with pHLH were collected in a multinational collaborative study. Eighty percent of the population was assessed to develop the score and the remaining 20% constituted the validation sample. Variables that entered the best fitted model of logistic regression were assigned a score, based on their statistical weight. The MAS/HLH (MH) score was made up with the i…
Dissecting the Heterogeneity of Macrophage Activation Syndrome Complicating Systemic Juvenile Idiopathic Arthritis
2015
Objective.To seek insights into the heterogeneity of macrophage activation syndrome (MAS) complicating systemic juvenile idiopathic arthritis (sJIA) through the analysis of a large patient sample collected in a multinational survey.Methods.International pediatric rheumatologists and hemato-oncologists entered their patient data, collected retrospectively, in a Web-based database. The demographic, clinical, laboratory, histopathologic, therapeutic, and outcome data were analyzed in relation to (1) geographic location of caring hospital, (2) subspecialty of attending physician, (3) demonstration of hemophagocytosis, and (4) severity of clinical course.Results.A total of 362 patients were incl…
Hemophagocytic syndrome in a patient with disseminated tuberculosis: a case report
2018
Hemophagocytic syndrome (HS) is a rare disorder of the immune system. It is characterized by fever, lymphadenopathy, hepatosplenomegaly, cytopenia and hyperferritinemia. The cause differs in each country suggesting a specific genetic background and epidemiology of infections, and it can be associated with malignant diseases. A rare cause of HS is tuberculosis (TB), we describe a case of HS associated with disseminated Mycobacterium tuberculosis (MT) infection in a patient from Sudan. He presented diarrhea, fever, pancytopenia, thickened and dilated bowel loops and lymph nodes enlargement at ultrasound and computed tomography scan. A bone marrow biopsy performed to rule out a lymphoma reveal…
