Electroacupuncture Regulation of Immune Cells in Herpes Zoster

February 1, 2026 updated by: Yan Shi, First People's Hospital of Hangzhou

The Regulatory Mechanisms of Electroacupuncture Intervention on Immune Cells in Herpes Zoster

Herpes Zoster (HZ), caused by the Varicella-Zoster Virus (VZV), is a common infection characterized by localized pain and blistering, with higher incidence in females. HZ affects patients' physical health, mental well-being, and quality of life. The immune system is critical in HZ pathogenesis. Studies show acupuncture relieves pain, modulates immunity, and may lower postherpetic neuralgia (PHN) risk. However, evidence is limited on whether electroacupuncture (EA) alleviates HZ by modulating immune cells. Using mass cytometry (CyTOF), this study will analyze peripheral immune cell changes pre- and post-EA to explore its regulatory effects on HZ immunity. This study will recruit HZ patients and healthy controls (HC), dividing patients into medication-only and medication+EA groups to assess EA's potential immunomodulatory effects in HZ treatment.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The study will enroll 8 HZ patients who meet the inclusion criteria and 3 age- and gender-matched healthy controls (HC). HZ patients will be randomly assigned in a 1:1 ratio to a medication-only group or a medication plus electroacupuncture group. All participants will receive Valacyclovir Hydrochloride tablets and Mecobalamin tablets. HZ-related immune cells in peripheral blood will be analyzed using CyTOF before treatment (day 0), during treatment (day 4), and after treatment (day 7). Pain intensity and characteristics will be assessed using the Visual Analogue Scale (VAS) and the Douleur Neuropathique 4 (DN4) questionnaire. Lesion healing (time to vesicle cessation, crusting, and scab detachment) and adverse events will also be recorded to evaluate lesion regression in HZ patients.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Peripheral blood immune cell levels
Time Frame: Before (Day 0), during (Day 4) and after (Day 7) treatment.
1. Custom Detection Panel: A 42-color detection panel is specifically designed according to the study objectives and target cell subpopulations. 2. Sample Collection and Processing: Peripheral blood (5 ml) is collected from patients into EDTA purple-top anticoagulant tubes, stored/transported at 4°C, and processed within 48 hours using Ficoll to isolate the PBMC layer, yielding a single-cell suspension of PBMCs. PBMCs can be cryopreserved for batch analysis or processed fresh for immediate analysis. 3. Staining and Analysis: Samples are stained and analyzed over two days. Surface antibodies are stained on the first day, followed by membrane permeabilization and intracellular antibody staining on the second day, before proceeding with CyTOF analysis.
Before (Day 0), during (Day 4) and after (Day 7) treatment.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Visual Analogue Scale
Time Frame: Before treatment (Day 0) and after each treatment (Day 1- Day 7).
The Visual Analogue Scale (VAS) is used to assess pain and is widely applied in clinical practice in China. The basic method involves a 10 cm sliding ruler with one side marked with 10 increments. One end is labeled "0," indicating no pain, and the other end is labeled "10," representing the most intense, unbearable pain.
Before treatment (Day 0) and after each treatment (Day 1- Day 7).
Douleur Neuropathique 4 questions
Time Frame: Before treatment (Day 0) and after each treatment (Day 1- Day 7).
The DN4 questionnaire consists of 10 items, with 7 items describing symptoms and 3 items related to clinical examination. Symptom descriptions include burning pain, cold pain, electric shock pain, tingling, pins and needles, numbness, and itching. Clinical examination includes decreased touch sensation, decreased pinprick sensation, and whether brushing in the painful area triggers or increases pain. Each item has "Yes" and "No" options, with "Yes" scored as 1 and "No" scored as 0, for a total score of 10. A score of ≥4 indicates a diagnosis of neuropathic pain.
Before treatment (Day 0) and after each treatment (Day 1- Day 7).
Lesion Regression Time
Time Frame: Before treatment (Day 0) and after each treatment (Day 1- Day 7).
The time for blister cessation, crusting, and scab shedding is recorded.
Before treatment (Day 0) and after each treatment (Day 1- Day 7).
Occurrence of adverse reactions
Time Frame: During the intervention.
Record the occurrence of adverse reactions.
During the intervention.
