AbstractBackground: Herpes zoster (HZ) is typically characterized by a burning, stabbing pain, hyperalgesia, and allodynia. In some patients, despite the lesions resolving, the pain persists and becomes chronic. If the pain continues for more than 6 months after the onset of the pain phase, this condition is called postherpetic neuralgia (PHN). The frequency and severity of PHN increase with advancing age. The pain in PHN can be severe, sometimes resistant to medications, significantly impacting the patients' quality of life. The elderly patient population cannot tolerate the medications due to their side effects. In this situation, interventional pain treatment should be applied in the elderly patient group who have a high risk of developing PHN compared to other age groups. Method: We included patients over 65 years of age with HZ-related pain who underwent dorsal root ganglion (DRG) pulsed radiofrequency (PRF) within the first 6 months from the onset of pain. We divided these patients into 2 groups: patients who underwent intervention within the first 1 month from the onset of pain and patients who underwent intervention between 1 and 6 months. We recorded medication doses and Numeric Rating Scale (NRS) scores before the procedure and at 1 week, 1 month, 3 months, and 6 months after the procedure. Results: After the DRG PRF treatment, NRS scores improved significantly in both groups (p < 0.05). The mean NRS score in the early DRG PRF group was significantly lower than that in the late DRG PRF group (p < 0.05). The medication doses in the early DRG PRF group were significantly lower than those in the other group (p < 0.05). Conclusions: Interventional pain treatment should be applied as soon as possible in the elderly patient group who do not respond to first-line medical treatment or cannot tolerate medical treatment due to its side effects and who have a high risk of developing PHN compared to other age groups. DRG PRF, applied in the early period of medical treatment-resistant acute HZ, is safe and effective, preventing the progression to PHN.Copyright © 2024 Gözde Dağıstan and Serdar Erdine.
