Abstract:
The association of mumps with peripheral facial paralysis has been suggested, but its pathogenesis remains unclear. An 8-year-old girl simultaneously developed left peripheral facial paralysis, ipsilateral cervical herpes zoster, and bilateral mumps sialadenitis. Elevated anti-mumps and anti-varicella zoster virus IgM antibodies in serological testing indicated recent infection of mumps and reactivation of VZV. Molecular studies have provided mounting evidence that the mumps virus dysregulates the host's immune system and enables the virus to proliferate in the infected host cells. This dysregulation of the immune system by mumps virus may have occurred in our patient, enabling the latent VZV infection to reactivate.
Insights
Mumps virus may trigger facial paralysis by weakening the immune system, allowing latent varicella-zoster virus (VZV) to reactivate. This case study explores the link between mumps, facial paralysis, and VZV reactivation.
Area of Science:
- Virology
- Immunology
- Neurology
Background:
- Peripheral facial paralysis is occasionally associated with mumps, but the underlying mechanisms are not well understood.
- Recurrent viral infections can impact immune system regulation, potentially leading to opportunistic reactivation of latent viruses.
Purpose of the Study:
- To investigate the potential role of mumps virus in the pathogenesis of peripheral facial paralysis.
- To explore the relationship between mumps infection, herpes zoster, and immune system dysregulation in a pediatric patient.
Main Methods:
- Case report of an 8-year-old girl presenting with simultaneous peripheral facial paralysis, cervical herpes zoster, and mumps sialadenitis.
- Serological testing for IgM antibodies against mumps virus and varicella-zoster virus (VZV).
Main Results:
- The patient exhibited serological evidence of recent mumps infection and VZV reactivation.
- Simultaneous occurrence of peripheral facial paralysis, ipsilateral cervical herpes zoster, and bilateral mumps sialadenitis was observed.
Conclusions:
- Mumps virus may dysregulate the host immune system, creating an environment conducive to the reactivation of latent varicella-zoster virus.
- This immune dysregulation by mumps virus could be a contributing factor to the development of peripheral facial paralysis and concurrent herpes zoster.
