Herpes zoster is reactivation of latent varicella-zoster virus resulting in dermatomal vesicular eruption, often with severe pain.
Recognition of Herpes Zoster (Shingles)'s full clinical spectrum improves diagnostic accuracy and therapeutic response.
Epidemiology and Clinical Significance
The prevalence and incidence of Herpes Zoster (Shingles) have been well-characterized through population-based studies.
- Factor 1: Reactivation of VZV from sensory nerve dorsal root ganglia
- Factor 2: Risk increases with age, immunosuppression, spinal cord trauma, malignancy
- Factor 3: Mechanical irritation may trigger reactivation
- Factor 4: Incidence increases significantly after age 50
Causes and Risk Factors
The pathophysiology of Herpes Zoster (Shingles) involves multiple interconnected biological pathways.
- Prodrome: pain, burning, or paresthesia in dermatomal distribution
- Eruption of grouped vesicles on erythematous base
- Severe dermatomal pain
- Constitutional symptoms less common than primary VZV
- Typically unilateral
- Crusting over 2-3 weeks
Pathophysiology and Disease Mechanisms
The pathophysiology of Herpes Zoster (Shingles) involves multiple interconnected biological pathways.
- Postherpetic neuralgia (pain persists after lesion healing)
- Secondary bacterial infection
- Ophthalmic zoster (vision-threatening)
- Facial involvement (Ramsay Hunt syndrome if with otitis)
Symptoms and Clinical Presentation
Symptom progression in Herpes Zoster (Shingles) correlates with underlying pathophysiological changes.
- Antivirals (acyclovir, valacyclovir, famciclovir) - most effective in first 72 hours
- Strong analgesics (opioids often needed)
- Topical antivirals and anesthetics
- Systemic corticosteroids (controversial but may reduce postherpetic neuralgia)
- Gabapentin or pregabalin for neuropathic pain
