背景情况:
- 血细胞淋巴细胞细胞瘤 (HLH) 是一种危及生命的超炎症综合征.
- HLH可以由病毒感染引发,包括严重急性呼吸系统综合征冠状病毒2 (SARS-CoV-2).
- 早期诊断和治疗HLH对于患者的生存至关重要,但诊断挑战仍然存在,特别是在危急病患者中.
研究的目的:
- 评估H-Score在严重病情的COVID-19患者的预后价值,怀疑二次HLH.
- 确定该患者队列中的H-Score值与死亡率之间的关联.
主要方法:
- 对208名入住ICU的重症COVID-19患者进行了回顾性队列研究.
- 通过文档审查收集的数据,至少进行90天的随访.
- 每个患者的H-Score计算,以评估HLH的可能性.
主要成果:
- 平均H分数为94±51;8.7%的患者H分数≥169,表明HLH.
- 具有H分数≥169的患者在28天 (66.7%对26.3%) 和90天 (72.2%对27.9%) 的死亡率显著更高.
- 高H-Score (≥169) 与严重病情的COVID-19患者28天和90天死亡率的增加密切相关.
结论:
- H-Score是一个有价值的预后工具,用于识别因二次HLH死亡风险较高的重症COVID-19患者.

Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...

Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver. The...
01:28Viral Hepatitis I: Introduction
Viral hepatitis is an inflammatory condition of the liver caused by infection with hepatotropic viruses, most commonly hepatitis A, B, C, D, and E. Despite variations in structure and transmission, all viruses mentioned infect hepatocytes and provoke immune responses that can hinder liver function. Additionally, some non-hepatotropic viruses can also lead to hepatic inflammation.Hepatitis A VirusHepatitis A virus (HAV) is transmitted through the fecal–oral route, typically by ingestion of food...
