Intradermal Exosomes, Platelet-Rich Plasma, and Steroids for Post-Herpetic Neuralgia
2026年4月27日 更新者:Mona El Radi Kamal Mohamed Emam、Zagazig University
A Comparative Study of Intradermal Injection of Exosomes, Platelet-Rich Plasma and Steroids in the Treatment of Post-Herpetic Neuralgia
This randomized controlled clinical trial will evaluate and compare the efficacy and safety of intradermal injection of exosomes, platelet-rich plasma, and corticosteroid in patients with post-herpetic neuralgia.
Forty-five adult patients with dermatomal pain persisting for at least 90 days after herpes zoster will be enrolled from outpatient clinics.
Participants will be assigned to one of three groups: intradermal exosome injection, intradermal autologous platelet-rich plasma injection, or intradermal triamcinolone acetonide injection.
Each group will receive four treatment sessions every two weeks.
Outcomes will include pain severity, neuropathic pain characteristics, quality of life, patient satisfaction, and adverse effects, assessed at baseline, at the final session, and during follow-up visits at 3 and 6 months after the last session.

有源比较器:皮质类固醇
|
Intradermal triamcinolone acetonide 10 mg/mL, 0.1 mL per 1 cm² square of the affected dermatome, every two weeks for four sessions
|
|
实验性的:Exosomes
Participants will receive intradermal injections of exosome product into the affected dermatome.
The dermatome will be marked and divided into 1 cm² squares, and 0.1 cc will be injected intradermally into each square using an insulin syringe.
Treatment will be given every two weeks for a total of four sessions, followed by visits at 3 and 6 months after the last session.

实验性的:PRP
Participants will receive intradermal injections of autologous platelet-rich plasma into the affected dermatome.
Ten mL of blood will be collected under aseptic conditions and centrifuged at 1000 rpm for 10 minutes.
The lower 1-2 cc of plasma will be used as platelet-rich plasma concentrate.
The affected dermatome will be marked into 1 cm² squares, and 0.1 cc PRP will be injected intradermally into each square.
Treatment will be given every two weeks for four sessions, followed by visits at 3 and 6 months after the last session.
