Efficacy of Tender Point Infiltrations (TPI) in Patients with Acute and Subacute Zoster-Associated Pain: Study...

Area of Science:

• Pain Management
• Neurology
• Clinical Trials

Background:

• Herpes zoster (HZ) significantly impacts patient quality of life, often leading to persistent postherpetic neuralgia (PHN).
• Current therapeutic options for HZ and PHN management are often insufficient, highlighting the need for novel treatment strategies.
• Tender point infiltration (TPI) is being explored as a potential analgesic therapy for acute and subacute HZ pain.

Purpose of the Study:

• To evaluate the analgesia efficacy and safety of TPI for acute and subacute HZ.
• To explore predictors for TPI's effectiveness in preventing PHN.

Main Methods:

• A randomized, prospective, multicenter, blinded endpoint, open-label controlled trial with 176 participants.
• Participants allocated 1:1 to standard care or TPI group, with a 12-month follow-up.
• Primary outcome: PHN presence at 12 months; secondary outcomes include pain scores (VAS), medication use, quality of life (WHOQOL-BREF), and patient satisfaction.

Main Results:

• Data analysis is ongoing; results will determine TPI's efficacy in reducing HZ pain and preventing PHN.
• Predictive factors for PHN prevention will be identified using multivariable logistic analyses.
• Safety will be assessed through adverse event monitoring throughout the trial.

Conclusions:

• This study aims to provide crucial evidence on TPI's role in managing HZ pain and preventing PHN.
• Findings will inform clinical practice and guide future research in pain management for HZ patients.
• Identifying predictors of successful TPI could personalize treatment strategies for PHN prevention.
