Insights

The International Herpes Management Forum (IHMF) reviewed Epstein-Barr virus (EBV) and human herpesvirus type 8 (HHV-8) central nervous system (CNS) diseases. Current diagnostic and treatment strategies for EBV-related CNS conditions require further investigation.

Area of Science:

  • Neurovirology
  • Immunology

Background:

  • Epstein-Barr virus (EBV) and human herpesvirus type 8 (HHV-8) can cause central nervous system (CNS) diseases.
  • EBV is linked to meningitis, encephalitis, and post-transplant lymphoproliferative disorder (PTLD).
  • HHV-8 CNS complications are rare but associated with AIDS-dementia complex, ALS, and primary CNS lymphoma.

Purpose of the Study:

  • To develop guidelines for managing herpesvirus infections of the CNS.
  • To review EBV and HHV-8 related CNS diseases.

Main Methods:

  • Literature review and expert consensus by the International Herpes Management Forum (IHMF).
  • Analysis of diagnostic approaches, including polymerase chain reaction (PCR) for EBV DNA in cerebrospinal fluid (CSF).

Main Results:

  • The pathogenesis of EBV-associated CNS disorders is not fully understood, potentially involving direct viral invasion or immune-mediated damage.
  • The diagnostic utility of PCR for EBV DNA in CSF is limited by undetermined sensitivity and specificity, and detection in asymptomatic individuals.
  • Antiviral therapy has shown no clinical efficacy for EBV-related CNS disorders.

Conclusions:

  • Improved management guidelines for EBV and HHV-8 CNS infections are needed.
  • Further research is required to clarify the role of HHV-8 in specific neurological conditions.
  • Diagnostic and therapeutic strategies for EBV-related CNS diseases require further development and validation.

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...

Encephalitis l: Introduction

Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...

Herpes

Herpes simplex type 1 (HSV‑1) is a widespread pathogen responsible for orolabial lesions. It is an enveloped, double-stranded DNA (dsDNA) virus belonging to the family Herpesviridae. Once the virus infects a host cell, its double‑stranded DNA genome is delivered into the nucleus, where a coordinated cascade of immediate‑early, early, and late gene expression directs viral DNA replication, structural protein synthesis, and virion assembly. After primary infection of epithelial cells, HSV-1...
Genital Herpes01:23

Genital Herpes

Genital herpes is a sexually transmitted infection primarily caused by herpes simplex virus type 2 (HSV-2), though herpes simplex virus type 1 (HSV-1) is increasingly implicated in genital infections, particularly among younger populations. Transmission occurs mainly through sexual contact, with asymptomatic viral shedding serving as a major route of spread. This characteristic makes HSV-2 difficult to control at a population level, as individuals may unknowingly transmit the virus even in the...
Arboviral Encephalitis01:25

Arboviral Encephalitis

Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...
Cytomegalovirus Disease01:27

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...
