Severe Adenovirus Infection Associated with Hemophagocytic Lymphohistiocytosis

Severe Fever with Thrombocytopenia Syndrome Virus Infection Associated with Hemophagocytic Lymphohistiocytosis as Poor Prognostic Factor

Severe dengue due to secondary hemophagocytic lymphohistiocytosis: A case study

Dengue, transmitted by the mosquito Aedes aegypti affects millions of people worldwide every year. Dengue induced hemophagocytic lymphohistiocytosis (HLH) is a serious condition and may prove fatal if not detected early and treated appropriately. Diagnosis of HLH is challenging and usually missed as clinical and laboratory findings are nonspecific. Moreover, the pathophysiology of the systemic ...

Hemophagocytic Lymphohistiocytosis Secondary to Salmonella paratyphi a Infection Presenting with Severe Pancytopenia and Multiorgan Dysfunction: The First Case Report

Hemophagocytic lymphohistiocytosis (HLH) or hemophagocytic syndrome is a life threatening hyperinflammatory condition caused by immune dysregulation and resulting in hemophagocytosis and organ damage by activated macrophages and histiocytes. The characteristic clinical features include fever, splenomegaly, cytopenias, liver dysfunction, and hyperferritinemia. HLH can be either primary (genetic)...

Hemophagocytic lymphohistiocytosis secondary to T-cell Acute Lymphoblastic Leukemia with membranous tonsillitis

Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening syndrome of excessive immune activation, which is characterized by fever, hepatosplenomegaly, cytopenias, hyperferritinemia, hypertriglyceridemia, and/or hypofibrinogenemia, and evidence of hemophagocytosis. Secondary HLH is often seen in adults and categorized based on autoimmune, infections-related, and malignancy-associated etiol...

The syndrome of hemophagocytic lymphohistiocytosis in primary immunodeficiencies: implications for differential diagnosis and pathogenesis.

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...
