hemophagocytic lymphohistiocytosis (hlh) is an aggressive and potentially life-threatening disease and has to be considered in the differential diagnosis of many conditions. hlh comprises two different conditions that are difficult to differentiate; familial hemophagocytic lymphohistiocytosis (fhlh) or familial erythrophagocytic lymphohistiocytosis (fel), and secondary hemophagocytic syndromes ...
Perforin gene (PRF1) mutations have been reported in 20-30% of patients with familial hemophagocytic lymphohistiocytosis (FHL), an immune disorder of infancy and early childhood. Cytotoxic T and natural killer (NK) cell activities are remarkably reduced or ab-sent in FHL patients. We report the first cases of familial hemophagocytic lymphohistiocy-tosis in an Iranian family with two siblings. E...
PURPOSE OF THE REVIEW One of the most perplexing features of systemic-onset juvenile rheumatoid arthritis is the association with macrophage activation syndrome, a life-threatening complication caused by excessive activation and proliferation of T cells and macrophages. The main purpose of the review is to summarize current understanding of the relation between macrophage activation syndrome an...
BACKGROUND Familial hemophagocytic lymphohistiocytosis is a genetic disorder of lymphocyte cytotoxicity that usually presents in the first two years of life and has a poor prognosis unless treated by hematopoietic stem cell transplantation. Atypical courses with later onset and prolonged survival have been described, but no detailed analysis of immunological parameters associated with typical v...
Primary familial hemophagocytic lymphohistiocytosis (HLH; or familial erythrophagocytic lymphohistiocytosis [FEL]) is a heterogeneous autosomal recessive disorder more prevalent with parental consanguinity. There is aggressive proliferation of activated macrophages and histiocytes, which phagocytose red blood cells (RBCs), white blood cells (WBCs), and platelets, leading to anemia, neutropenia ...

BACKGROUND Familial hemophagocytic lymphohistiocytosis is a fatal disease characterized by immune dysregulation from defective function of cytotoxic lymphocytes. Three causative genes have been identified for this autosomal recessive disorder (PRF1, UNC13D, and STX11). We investigated the molecular genetics of familial hemophagocytic lymphohistiocytosis in Korea. DESIGN AND METHODS Pediatric ...
Expression of Hemophagocytic Lymphohistiocytosis with Hepatic Dysfunction in a 50 days Old Infant L. Borjian MD , H. Nazmieh MSc Received: 27/03/07 Sent for Revision: 13/06/07 Received Revised Manuscript: 08/07/07 Accepted: 26/07/07 Background and Objective: The Hemophagocytic Lymphohistiocytosis (HLH) is a rare disease with the pathologic hallmark of having aggressive proliferation o...
Hemophagocytic lymphohistiocytosis is a hyperinflammatory syndrome defined by clinical and laboratory criteria. Current criteria were created to identify patients with familial hemophagocytic lmyphohistiocytosis in immediate need of immunosuppressive therapy. However, these criteria also identify patients with infection-associated hemophagocytic inflammatory states lacking genetic defects typic...
