In hematology, hemophagocytic lymphohistiocytosis (HLH), also known as haemophagocytic lymphohistiocytosis (British spelling), and hemophagocytic or haemophagocytic syndrome, [1] is an uncommon hematologic disorder seen more often in children than in adults.

2022年10月13日 · What is hemophagocytic lymphohistiocytosis? Hemophagocytic lymphohistiocytosis (HLH) is a condition that occurs when your immune system abnormally overreacts. Your immune system defends your body from things that make you sick, like bacteria and viruses. Cells, proteins, organs and tissues work together to keep you healthy.

Hemophagocytic lymphohistiocytosis (HLH) is a rare disorder of inflammation that was first thought to affect only young infants and children but is increasingly recognized in older children and adults.

Hemophagocytic lymphohistiocytosis (HLH) is a rare immune system disease. It occurs more often in babies and young children. But it can also occur in adults. Children may inherit the disease through genes. This is called familial HLH. But in adults, many conditions can cause HLH. This is called acquired HLH.

2013年12月6日 · HLH is the consequence of a severe, uncontrolled hyperinflammatory reaction that in most cases is triggered by an infectious agent. Persistent stimulation of lymphocytes and histiocytes results in hypercytokinemia, leading to the characteristic symptoms of HLH.

Hemophagocytic lymphohistiocytosis (HLH) is a rare and potentially life-threatening disease process resulting from uncontrolled activation of the immune system. Raising money to fund scholarships and other programs for students pursuing an agriculture-based degree program.

2011年10月13日 · Here, we review the clinical manifestations and patterns of HLH and describe our approach to the diagnosis and therapy for this elusive and potentially lethal condition. Hemophagocytic lymphohistiocytosis (HLH) is a syndrome of pathologic immune activation characterized by clinical signs and symptoms of extreme inflammation.

2024年7月19日 · Hemophagocytic lymphohistiocytosis (HLH) is a rare but potentially fatal disease of normal but overactive histiocytes and lymphocytes that commonly appears in infancy, although it has...

2019年9月18日 · Hemophagocytic lymphohistiocytosis is a rare, life-threatening syndrome characterized by abnormal, excessive activation of the immune system. Imaging plays an important role in determining the extent of involvement of hemophagocytic lymphohistiocytosis.

Hemophagocytic lymphohistiocytosis (HLH) is a non-malignant, life-threatening hyperinflammatory condition resulting from dysregulation of normal innate and adaptive immune responses. Defects in immune effector cell cytotoxic mechanisms have been identified in many HLH syndromes.
