Herpesviruses and the microbiome

Area of Science:

• Immunology
• Virology
• Dermatology

Background:

• Eight human herpesviruses (HHV) are common, establishing lifelong infections and forming part of the human microbiome.
• Atopic individuals exhibit a TH2 cytokine profile, potentially influencing their immune response to herpesviruses.
• Herpesviruses can cause severe illness, like eczema herpeticum, in atopic patients, and reactivation is linked to syndromes like DRESS.

Purpose of the Study:

• To examine the role of common herpesviruses in the atopic microbiome.
• To review clinical evidence of atopic predisposition to severe herpes-related illness.
• To explore how herpesvirus infections might alter the atopic phenotype.

Main Methods:

• Literature review of clinical observations and scientific evidence.
• Analysis of herpesvirus interactions with the human immune system.
• Examination of viral mechanisms affecting host cytokine profiles.

Main Results:

• Atopic patients may present with atypical or more severe herpesvirus infections, including eczema herpeticum.
• Reactivation of herpesviruses can alter host cytokine profiles via viral proteins and nucleic acids.
• Childhood herpesvirus infections may influence the development of atopic phenotypes.

Conclusions:

• Physicians must recognize diverse herpes-related disease presentations in atopic patients.
• Accurate diagnosis is essential to avoid misdiagnosis of conditions like drug allergy or autoimmune disease.
• Timely administration of antiviral therapy and vaccines is clinically indicated for herpesvirus infections in atopic individuals.
