Study Notes
- Herpesviridae are large double-stranded DNA viruses that replicate in the nucleus of the host cell.
- There are alpha, beta, and gamma herpesviruses that establish latent infection in lymphocytes.
- Human herpesvirus classification includes HSV-1, HSV-2, VZV, EBV, CMV, and KSHV.
- HSV-1 and HSV-2 share several cross-reactive epitopes with each other and antigenic cross-reaction with VZV.
- HSV is primarily transmitted through saliva and sexual contact.
- HSV-1 causes acute gingivostomatitis, cold sores, keratoconjunctivitis, and encephalitis.
- HSV-2 causes genital herpes and neonatal herpes infection.
- Neonatal herpes infection can lead to death and intellectual disability.
- Diagnosis can be made through culture, detection of antigen, viral DNA, or cytology.
- Antiviral chemotherapy with acyclovir is the drug of choice for most situations.
- Varicella is a primary infection resulting in chickenpox.
- Shingles is a reactivation of varicella-zoster.
- Cytomegalovirus is a double-stranded DNA enveloped virus.
- Most CMV infections are asymptomatic.
- EBV is the most common cause of infectious mononucleosis.
- Burkitt's lymphoma is the commonest childhood tumor in parts of Africa.
- Hodgkin's lymphoma is often diagnosed in people between 15 and 30 years old.
- Nasopharyngeal carcinoma is prevalent in S. China.
- HHV-6 and HHV-7 are closely related subtypes of herpesviruses.
- Treatment for these viruses includes antiviral medications and hyperimmune globulin.
- NPC is associated with the V genome and EBV EBNA-1 antigen, and patients have high titers of antibodies against various EBV antigens.
- NPC prognosis is poor due to late presentation.
- Environmental and genetic factors may also contribute to NPC.
- EBV can reactivate in immunocompromised patients, leading to lymphoproliferative lesions and lymphoma in unusual sites.
- X-linked lymphoproliferative syndrome is a fatal condition associated with EBV.
- Oral hairy leukoplakia is triggered by EBV and occurs in patients with weak immune systems.
- Diagnosis of EBV can be done through detection of atypical lymphocytes or serology.
- There is no effective treatment or vaccine for EBV.
- HHV-8 is associated with Kaposi's sarcoma and other malignancies.
- HHV-8 has low seroprevalence in the general population.
