A 10-year-old male with a brain abscess developed pancytopenia, liver dysfunction, disseminated intravascular coagulation (DIC) and decrease of immunoglobulin A (IgA) level during postoperative antibiotic and anticonvulsant therapy. A bone marrow examination revealed hemophagocytosis. Real-time PCR revealed parvovirus B19 infection. The hemophagocytic syndrome resolved without specific treatmen...

Infection-associated hemophagocytic syndrome is a life-threatening condition characterized by prolonged fever, hepatosplenomegaly, and cytopenia-most commonly, thrombocytopenia and anemia. It is characterized by proliferation and activation of benign histiocytes, causing dysfunction of various organs. Herein, we report on a 5-month-old boy whose clinical picture and laboratory findings were con...

A 16 year old lebanese girl with consanguinous parents presented with a severe “abdominal” sepsis supposedly resulting from an infected vaginal tampon (ESBL E.coli). She had been healthy before. She developed severe hepatic functional disorder, infarction of the spleen, cardiovascular and renal insufficiency, as well as anemia and thrombocytopenia. Macrophage activation syndrome was diagnosed s...

BACKGROUND Lymphoma-associated hemophagocytic syndrome (LAHS) occurs in mostly extra nodal non-Hodgkin's lymphoma. LAHS arising from gastrointestinal lymphoma has never been reported. Here we report a case of gastric T-cell lymphoma-associated hemophagocytic syndrome. CASE PRESENTATION A 51-year-old woman presented with pain, redness of breasts, fever and hematemesis. Hematological examinatio...

OBJECTIVE To investigate the frequency of hemophagocytic syndrome in a series of patients with otherwise unexplained cytopenia. MATERIAL AND METHOD In this cross-sectional, single-centre study, bone marrow specimens (n=288) were obtained from the patients with unexplained cytopenia. The diagnosis of hemophagocytic syndrome was made according to universally accepted criteria. Characteristics o...

Figure 1. May-Grünwald-Giemsa staining (original magnification, ϫ1000) of the patient's bone marrow aspirate (left panel), showing unstained oblong shapes (white arrows) in the cytoplasma of several macrophages, and Ziehl-Neelsen staining of the same area (right panel), revealing the unstained objects to be acid-fast bacilli (black arrows). Diagnosis: hemophagocytic syndrome due to disseminated...

BACKGROUND Macrophage activation syndrome (MAS) is a severe, potentially life-threatening condition induced by chronic rheumatic diseases, especially systemic-onset juvenile idiopathic arthritis (SoJIA) in childhood. This study aimed to analyze the clinical and laboratory characteristics of systemic-onset juvenile idiopathic arthritis (SoJIA) with macrophage activation syndrome (MAS) in 13 pati...

Several trials for the COVID-19 pandemic are found. Prof. Shunji Nakamura, Tokushima University was awarded 2014 Nobel prize in Physics light-emitting diodes (LEDs). Deep ultraviolet LED (DUV-LED) causes SARS-CoV-2 inactivation as 99.9% by 265 nm. Gc protein-derived macrophage-activating factor (GcMAF)-based immunotherapy has a wider application serious infection, chronic fatigue syndrome, and ...

Hemophagocytic lymphohistiocytosis is character-ized by fever, hepatosplenomegaly, cytopenia, hyper-triglyceridemia, hypofibrinogenemia, and hemophago-cytosis. Ascites is not mentioned as a symptom of hemophagocytic syndrome. We report a one month-old girl suffering from familial erythrophagocytic lympho-histiocytosis, who presented with ascites.
