Background: Herpes zoster (HZ) is an acute dermatological condition caused by the varicella-zoster virus. Its onset is characterized by severe pain, imposing significant physical and psychological burdens on patients. Acupuncture offers distinct advantages in treating acute herpes zoster and associated pain. However, the therapeutic efficacy of electroacupuncture for acute herpes zoster, its potential to reduce PHN incidence, and the role of biomarkers in predicting PHN incidence require further clinical validation. Methods: A total of 228 patients with acute herpes zoster will be recruited from 3 hospitals and randomly assigned to EA group or medication-alone group or sham acupuncture group in a 1:1:1 ratio, utilizing multicenter stratified block randomization. The trial will involve a 2 week treatment period, and a 3-month follow-up period. All variables will be evaluated at week 0, week 1, week 2, and on the 90th day after rash onset. All participants will continue antiviral medication treatment. Primary outcome is Numerical Rating Scale; secondary outcomes include herpes lesion crusting time, pain episodes within a 24-hour period, Hamilton Anxiety Scale, Hamilton Depression Scale, 36-Item Short Form Health Survey, changes of biomarkers (Erythrocyte sedimentation rate, C-reactive protein, Tumor Necrosis Factor-α, Interleukin-10, Substance P and neuropeptide Y) and PHN incidence rate. All adverse effects will be assessed during the trial. Conclusion: This study will elucidate the efficacy of electroacupuncture in treating acute herpes zoster, whether electroacupuncture can reduce the incidence of PHN, and the role of biomarkers in predicting the incidence of PHN.
