Study summary

Herpes zoster (HZ) is a skin infection disease which cause severe zoster-associated pain (ZAP) along sensory nerve in the corresponding segment. Evidence for the efficacy of existing local therapies for acute/subacute ZAP is limited. The hypothesis is that patients with acute/subacute ZAP treated with TPIs with local anesthetic and steroids under the basis of standard treatment will show better clinical outcomes compared with subjects treated with standard antiviral medicine treatment only.

Read the detailed description

The conventional therapies for HZ infection can be seen in two phases. Those in acute phase are mainly antiviral (acyclovir, famciclovir, etc.), analgesic drugs (opioids, acetaminophen or nonsteroidal anti-inflammatory agents, gabapentin, etc.), while these conventional drug therapies could yield potential side effects, and part of patients are not fully satisfied with the analgesic effect. It is considered that supplementary and alternative local therapies may have better results with less side effects and reduce medical costs to relieve pain associated with HZ infection. These options, including nerve blockade (epidural injection, paravertebral injection, sympathetic block, intercostal nerve block, intracutaneous injection), pulsed radiofrequency16, acupuncture, fire needling acupuncture, electrical nerve stimulation19, lidocaine patch, capsaicin cream, and botulinum toxin injection have been reported to give positive therapeutic effects on acute herpes zoster neuralgia (AHN), however, evidence for the efficacy of existing local therapies is limited and risks may occur due to high invasiveness of some procedures, there is insufficient evidence and expert agreement to make recommendations for these intervention strategies as first-line treatments in guidelines.

Study arms

  • Active comparator
    Standard gorup

    Patients will receive standard oral medicine for herpes zoster.

    Drug: analgesic

  • Experimental
    TPI group

    Patients will receive standard medicine treatment and tender point infiltrations therapy.

    Drug: analgesic · Behavioral: Tender point infiltration

Interventions

  • Druganalgesic

    Patients will receive daily 300 mg pregabalin in divided doses (150 mg/12 hours). Once the patient report mild pain (VAS ≤ 3), the trial for reducing the pregabalin dose will be done. Nonsteroidal anti-inflammatory drug celecoxib (200 mg on request, up to two times daily)27 and tramadol (100 mg on request, up to 400mg daily) will be available for as-needed analgesia.

    Also known as: Standard treatment

  • BehavioralTender point infiltration

    Lidocaine mixed with diprospan injected into tender points.

    Also known as: TPI infiltration

What researchers measure

Primary outcomes

  1. The presence of postherpetic neuralgia using VAS score

    12 months after the treatments, number of patients with any pain with a VAS score of higher than 0/Number of all patients,0="no pain" and 10="worst pain imaginable"

    Time frame: 12 months

Secondary outcomes

  1. visual analogue scale score at each time point

    0 = 'no pain at all' to 10 = 'worst pain imaginable'

    Time frame: before the treatment (baseline), 30min after the intervention (for TPI group), then 1 day, 2 weeks, 1 month, 3 months, 6 months and 12 months following the treatment

  2. Proportion of patients receiving repeated TPIs and block points

    Number of patients receiving TPI treatments more than twice/Number of all patients

    Time frame: 12 months

  3. Consumption of oral drugs at each time point

    Dose of celecoxib, pregabalin and tramadol

    Time frame: day 1, then 2 weeks, 1 month, 3 months, 6 months and 12 months following the treatment.

  4. The presence of PHN at month 3 and month 6 post treatment

    Number of patients with any pain with a VAS score of higher than 0/Number of all patients (0 = 'no pain at all' to 10 = 'worst pain imaginable')

    Time frame: 3 and 6 months after treatments

  5. Patient satisfaction scores on the 5-point Likert scale

    1: Very dissatisfied,2: Dissatisfied,3: Not sure,4: Satisfied,5: Very satisfied

    Time frame: day 1, then week 2, month 1, month 3, month 6 and month 12 following the treatment

  6. Quality of life on the Scores on the WHOQOL-BREF

    Scores on the WHOQOL-BREF. The responses are given on 5-point Likert scale (1-5) and the overall score ranges from 0 to 100; a higher score corresponds to better QoL.

    Time frame: day 1, then week 2, month 1, month 3, month 6 and month 12 following the treatment

  7. Adverse reactions through study completion

    Any side effect and uncomfortable situation related to treatment through study completion,an average of 1 year

    Time frame: After treatments

  8. Predictive factors for the prevention of PHN at month 12 posttreatment

    the correlation between patients' baseline characteristics and the incidence of PHN will be analyzed 12 months after treatment in TPI group.

    Time frame: month 12 posttreatment
