Eczema Herpeticum

Slide 22

Eczema Herpetcium Illness Script Predisposing Conditions Eczematous skin disease: Atopic dermatitis Most common skin disease in children (20% prevalence) More frequently in urban areas, higher socioeconomic classes + family history of atopy Prone to infections with S. aureus and HSV** Can occur at any age, most common 2-3 years old Exposure to caregiver with HSV Immunocompromised patient HSV can be reactivated by fever, sunlight, trauma, stress

Slide 23

Eczema Herpetcium Illness Script Pathophysiology Defective skin barrier Most children, caused by primary HSV infection Incubation period of 4-11 days after HSV infection, then eruption of lesions Dysregulation of cell-mediated and humoral immunity in patients with atopic dermatitis Allows HSV to proliferate Common complication: Bacterial superinfection with staph or strep

Slide 24

Eczema Herpetcium Illness Script Clinical Manifestations** Eruption of multiple vesiculopustular lesions in disseminated pattern Grouped fluid filled vesicles on an erythematous base After several days, vesicles pustules rupture and become crusted, have punched-out appearance May coalesce, erode and ooze hemorrhagic exudate Irritability Pruritis Fever Anorexia, malaise, vomiting, diarrhea, lymphadenopathy Systemic and CNS spread have been reported

Slide 25

Diagnosis** Clinical diagnosis Gold standard: viral culture (not very sensitive) HSV DNA PCR from vesicle fluid Direct fluorescent antibody testing of cells from vesicle scrapings Stain with Giemsa or Wrights stain (Tzanck test) Very specific but not very sensitive Can visualize multi-nucleated giant cells Can indicate an HSV or Varicella-zoster infection

Slide 26

Treatment Early treatment is essential to prevent fulminant progression and possible mortality ALL children should receive systemic acyclovir for 5- 7days MOST should have IV acyclovir If patient appears well/limited disease, can do PO Can treat longer for severely affected children Give until no new lesions appear Local skin care, supportive care Treat with antibiotics for any suspected bacterial infection Discontinue topical steroids
