Overview
Multidermatomal herpes zoster infection involves widespread rash and pain due to reactivation of varicella-zoster virus beyond the typical dermatomal distribution. This condition can present with severe complications, including systemic manifestations such as myoglobinuria and involvement of other organs like the gastrointestinal tract 12.Diagnosis
Clinical presentation of widespread vesicular rash and pain
Laboratory tests: VZV PCR or serology to confirm infection 12
Imaging or endoscopy may be indicated for suspected visceral involvement (e.g., gastritis) 2Management
First-line antiviral therapy: Acyclovir, Valacyclovir, or Famciclovir (dose specifics not provided in abstracts) 12
Adjunctive treatments: Pain management with analgesics, including opioids if necessary
Supportive care: hydration, monitoring for complications like renal failure 1Special Populations
Pregnancy: Specific management guidelines not covered in provided abstracts 12
Pediatrics: No specific details provided in abstracts 12
Elderly: Increased risk of severe complications; close monitoring recommended 1
Comorbidities: Patients with renal impairment require careful monitoring for myoglobinuria and acute renal failure 1Key Recommendations
Initiate antiviral therapy promptly upon diagnosis to reduce viral shedding and severity (Evidence: Moderate) 12
Monitor for and manage systemic complications, particularly renal function and myoglobinuria, especially in high-risk groups (Evidence: Weak) 1
Consider endoscopic evaluation if gastrointestinal symptoms suggest herpetic gastritis (Evidence: Expert opinion) 2References
