概括

人类疹病毒6 (HHV-6) 的重新激活会导致急性肝衰竭 (ALF),特别是在免疫功能低下的人群中. 这一案例突出显示,HHV-6B是患有营养不良和酒精滥用的年轻女性ALF的潜在原因.

科学领域:

肝病学肝病学是一种肝病学.
病毒学病毒学
免疫学免疫学免疫学

背景情况:

人类疹病毒6 (HHV-6) 感染通常无症状,但在免疫功能低下的人群中可能导致严重疾病.
包括急性肝衰竭 (ALF) 在内的肝损伤已在免疫功能低下和免疫能力强的成年人中报告.
在特定患者群体中,HHV-6是已知的重大发病原因.

研究的目的:

报告由人类疹病毒6B (HHV-6B) 再激活引起的急性肝衰竭 (ALF) 病例.
强调在未知病因的ALF的差异诊断中考虑HHV-6的重要性.
探索可能导致HHV-6重新激活和随后的ALF的潜在因素.

主要方法:

一个20岁的女性被诊断出患有ALF的案例报告.
诊断工作包括在外周血液和肝脏组织中检测HHV-6B.
分析了临床表现和患者病史,以确定易感因素.

主要成果:

患者出现了ALF的症状,包括肝脏脑病变.
鉴定出HHV-6B是ALF的致病原体.

Chickenpox

Chickenpox

Chickenpox is an acute, highly contagious disease caused by the varicella-zoster virus (VZV), a double-stranded DNA virus belonging to the Herpesviridae family. Its transmission occurs primarily through the inhalation of respiratory droplets or direct contact with vesicular fluid from skin lesions. The incubation period typically ranges from 10 to 21 days, during which the virus replicates and disseminates through sequential phases within the host. Although generally self-limiting in children,...

Cytomegalovirus Disease

Cytomegalovirus Disease

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

Hepatitis

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...

Encephalitis ll: Pathophysiology

Encephalitis ll: Pathophysiology

Encephalitis is inflammation of the brain parenchyma caused by direct viral invasion or immune-mediated mechanisms triggered by infections or tumors. Both processes lead to neuronal injury, disrupted neurotransmission, and diverse neurological symptoms, often with overlapping clinical and pathological features.Autoimmune EncephalitisIn autoimmune encephalitis, antibodies target neuronal antigens on cell surfaces, synapses, or within neurons. A key example is anti-NMDAR encephalitis, which can...

Viral Hepatitis I: Introduction

Viral 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...

Hepatic Encephalopathy

Hepatic Encephalopathy

DefinitionHepatic encephalopathy is a reversible neurologic syndrome that results from advanced liver dysfunction or portosystemic shunting. It leads to disturbances in cognition, behavior, and motor function due to the brain’s exposure to gut-derived toxins that the liver fails to detoxify.EtiologyThis condition develops either in the setting of acute fulminant hepatitis or progressively during chronic liver disease, such as cirrhosis and portal hypertension. Portosystemic shunting—including...
