BACKGROUND Kala-azar is a multisystem infection of the reticuloendothelial system. Various hematologic abnormalities have been described in kala-azar including hemophagocytic syndrome (HPS).  METHODS We reviewed bone marrow aspirate smears from 18 documented cases of kala-azar complicated by HPS.  RESULTS The bone marrow smears were hypercellular with erythroid hyperplasia. Megaloblastic ch...

A 16-month-old girl was diagnosed with Epstein-Barr virus hemophagocytic lymphohistiocytosis and transferred to our hospital on the 58th day of the hemophagocytic lymphohistiocytosis after treatment failure according to the Hemophagocytic Lymphohistiocytosis-2004 protocol. On admission to our hospital, she had a flaccid paralysis of her lower limbs. Nerve conduction studies showed a acute motor...

he fulminant hemophagocytic syndromes, as recently defined by Cline, are aggressive and often fatal disorders, most frequent in children but occurring in all ages, that are characterized by fever, systemic symptoms, jaundice, multiple organ failure, coagulopathy, and phagocytosis of blood elements with cytopenias. Death may occur in up to 40% of cases. A distinction is generally made between fa...

Hemophagocytic lymphohistiocytosis is a potentially fatal disease characterized by excessive macrophage and lymphocyte activity. Patients can be affected following immune activation after an oncologic, autoimmune or infectious trigger. An associated gene mutation may be found which impairs cytolytic lymphocyte function. We describe a pediatric case of hemophagocytic lymphohistiocytosis with a n...

Hemophagocytic lymphohistiocytosis is a rare complication of dengue. We present 8 cases of dengue associated hemophagocytic lymphohistiocytosis diagnosed in our hospital during the dengue outbreak of 2012. All the cases were treated with a short (4 weeks) course of steroids along with supportive measures, and showed an excellent response.

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.

Hemophagocytic lymphohistiocytosis (hemophagocytic syndrome, HLH, HPS) is the group of severe life-threatening and hardly diagnosing conditions caused by immune dysregulation because systemic inflammatory response with non-controlled proliferation activation T-cells, monocytes macrophages accumulation in target organs development multiple organ failure. HLH are includes primary (monogenic) seco...

Virus-associated hemophagocytic syndrome is a fulminant disorder associated with systemic viral infection and characterized pathologically by multiple-organ infiltration of hemophagocytic histiocytes into the lymphoreticular tissues. This is the first report of a previously healthy adult in whom Human herpesvirus 6 reactivation induced this syndrome with severe hemodynamic and respiratory distr...

The MR imaging appearance of a case of virus-associated hemophagocytic syndrome complicated by diffuse CNS infiltration is presented. Virus-associated hemophagocytic syndrome is a rare condition, precipitated by viral infection and characterized by proliferation of benign histiocytes with phagocytosis. In severe cases, the CNS may be involved.

cytomegalovirus is the most common viral infection after kidney transplantation. clinical presentations of cytomegalovirus infection range from asymptomatic infection to organ-specific involvement. most symptomatic infections manifest as fever and cytopenia. the gastrointestinal tract is the most common site of tissue-invasive infection, often presenting as diarrhea or gastrointestinal bleeding...
