Hemophagocytic lymphohistiocytosis (HLH) is a rare disease that usually occurs in infants and young children. It may also occur in adults. Children usually inherit the disease. In adults, many different conditions, including infections and cancer, can cause HLH.

Hemophagocytic lymphohistiocytosis, also called HLH, is an immune deficiency disorder. In this type of disorder, part of the immune system is missing or defective. That means the body can’t fight infections as it should. As a result, a person with HLH may have frequent infections that are generally more severe and last longer than usual.

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.

噬血细胞综合征（HLH）被认为是一种单核巨噬系统 反应性 增生的 组织细胞 病，主要是由于 细胞毒 杀伤细胞 （CTL）及 NK细胞 功能缺陷 导致抗原清除障碍，单核巨噬系统接受持续抗原刺激而过度活化增殖，产生大量 炎症细胞因子 而导致的一组临床综合征。 噬血细胞综合征主要表现为 发热 、 脾大 、 全血细胞减少 、高甘油三酯、低 纤维蛋白原 、高 血清铁蛋白，并可在骨髓、脾脏或 淋巴结活检 中发现噬血现象。 噬血细胞综合征主要分为 原发性 （遗传性）及继发性。 前者 …

2022年10月13日 · Hemophagocytic lymphohistiocytosis is a rare and often life-threatening condition if left untreated. HLH causes your immune system to attack your body instead of a foreign invader like a virus. The condition is either acquired or genetic and there’s no way to prevent it. Treatment is available and most effective with an early diagnosis.

2024年6月5日 · HLH causes a hemorrhagic form of DIC with increased risk of bleeding due to low fibrinogen levels. Prior to lumbar puncture, consider checking a fibrinogen level, coagulation studies, and complete blood count. Basic chemistry findings may include elevated protein levels and lymphocytic pleocytosis.

2023年3月27日 · Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening, hyper-inflammatory disorder affecting both newborns and adults alike. The disease is characterized by dysregulated immune activity resulting in malignant inflammation and multi-organ failure.

促黄体生成素（lh）主要是由垂体分泌的一种生殖激素，它存在于男性和女性中的作用都不相同，在男性中能帮助睾丸间质细胞分泌男性激素，在女性中能够帮助卵巢分泌女性雌激素。

黄体生成素 （luteinixing hormone,LH)促使卵泡内膜细胞增生发育合成雄激素，提供颗粒细胞合成雌激素的原料。 月经中期的LH峰对卵泡发育成熟及排卵至关重要，并促使颗粒细胞得卵泡内膜细胞于排卵后转化为黄体细胞，黄体细胞分泌雌、孕激素。 一、LH的合成. LH与FSH一样亦由垂体前叶嗜碱性细胞分泌。 LH和FSH都是 糖蛋白激素，由两个亚基组成。 同样在GnRH作用下， 垂体前叶 分泌LH形成浓缩小泡留在储备池中，但LH与FSH分别位于不同的小泡中。 卵泡期雌二醇 …
