Eczema herpeticum — Clinical Guidelines

Overview

Eczema herpeticum is a severe, disseminated viral infection, typically caused by herpes simplex virus (HSV), occurring in patients with pre-existing atopic dermatitis or other eczematous conditions, leading to painful skin lesions and potential systemic complications 4.

Diagnosis

Clinical presentation of multiple, painful, fluid-filled vesicles or ulcers in eczematous skin lesions 4.

Histopathological examination may reveal viral cytopathic effects 4.

Polymerase chain reaction (PCR) testing of skin lesions for HSV DNA can confirm the diagnosis 4.

Blood cultures and viral cultures may identify concurrent bacterial infections like methicillin-resistant Staphylococcus aureus 4.

Management

Antiviral therapy: Initiate with acyclovir or valacyclovir for HSV infection 4.

Antibiotics: Consider for secondary bacterial infections, especially methicillin-resistant Staphylococcus aureus 4.

Supportive care: Including fluid resuscitation, pain management, and monitoring for sepsis and multiorgan failure 4.

Corticosteroid tapering: Gradually reduce systemic corticosteroids if applicable to avoid immunosuppression 4.

Special Populations

Immunocompromised patients: Higher risk of severe complications and mortality; close monitoring essential 4.

No specific pediatric or elderly considerations mentioned in the provided abstracts.

Key Recommendations

Maintain a high index of suspicion for eczema herpeticum in patients with eczematous conditions presenting with disseminated vesicular lesions, especially if immunocompromised (Evidence: Strong 4).

Prompt initiation of antiviral therapy (acyclovir/valacyclovir) is crucial for managing HSV infection in eczema herpeticum (Evidence: Strong 4).

Concurrent bacterial infections should be aggressively treated, particularly methicillin-resistant Staphylococcus aureus, to prevent sepsis (Evidence: Moderate 4).
