Acupuncture in Herpes Zoster Neuralgia (ACUZoster)

Analgetic Effectiveness of Acupuncture When Compared to a Standardised Analgesic Regimen in the Treatment of Herpes Zoster Neuralgia

Symptoms that herald herpes zoster include pruritus, dysesthesia and pain along the distribution of the involved dermatome. The most distressing symptom is typically pain and the most feared complication is postherpetic neuralgia (PHN), the persistence of pain long after rash healing. PHN is defined as pain persisting more than 3 months after the rash has healed. Both, the acute pain associated with herpes zoster and the chronic pain of PHN, have multiple adverse effects on health-related quality of life.

The primary objective of the trial presented is to investigate whether a 4 week semi-standardised acupuncture is non-inferior (first step) or superior (second step) to (a) the anticonvulsive drug gabapentin and (b) sham laser acupuncture in the treatment of pain associated with herpes zoster in addition to standardised analgesics. Secondary objectives include an assessment of the change of sensoric function, of long-term effectiveness, the occurrence of PHN and an evaluation of several pain specific questionnaires
