Effects of Acupuncture for Senile Pruritus
- Conditions
- Senile Pruritus
- Interventions
- Other: Acupuncture
- Registration Number
- NCT06506240
- Brief Summary
Senile pruritus (SP), characterized by idiopathic itching in individuals aged 60 years and older without primary skin lesions, significantly impacts sleep and quality of life. Effective alternative treatments are needed. Acupuncture has been suggested as a potential intervention to alleviate itching; however, its role in managing SP remains uncertain. This study aims to evaluate the effects and safety of acupuncture for SP. This single-centre, parallel, two-arm, randomized, sham-controlled trial will enroll 108 patients diagnosed with SP in a 1:1 ratio to either the acupuncture or sham acupuncture group. Participants, outcome assessors, and the statistician will be blinded. Treatment will consist of 18 sessions over 6 weeks. The primary outcome is change from baseline in the Numerical Rating Scale (NRS) score for average itching severity at week 6, assessed weekly via weekly diary of pruritus assessment. Secondary outcomes include changes in NRS score for maximum itching severity, daily episodes of itching, itchy area of body surface, overall dry skin score (ODS), the Dermatology Life Quality Index (DLQI), the Pittsburgh Sleep Quality Index (PSQI), the Hospital Anxiety and Depression Scale (HADS), and Patient Global Impression of Change (PGIC). Adverse events will be monitored throughout the study period. The intention-to-treat (ITT) population will include participants who complete baseline assessments and receive at least one treatment session.

Group Intervention Description Sham acupuncture group Acupuncture Patients in the control group will undergo sham acupuncture using sterile disposable stainless-steel needles (0.3 mm×25 mm; Hwato brand, Suzhou Medical Appliance Factory, Suzhou, China). Needles will be inserted to depths of 2 to 3 mm at the same acupuncture points as in the acupuncture group. There will be no needle manipulation or attempt to induce Deqi sensation. Needles will be retained for 30 minutes per session. Acupuncture group Acupuncture Treatment will be administered by licensed practitioners with over five years of experience, in separate rooms to prevent patient interaction. The selected acupuncture points include LI11 , SP10, ST36, SP6, LR3, LI4, ST25, CV4, GV20, and superior GV29. Sterile disposable stainless-steel needles (0.3 mm×40 mm; Hwato brand, Suzhou Medical Appliance Factory, Suzhou, China) will be used. Patients will lie supine, and routine skin sterilization will be performed locally. Needles will be inserted at depths ranging from 10 to 30 mm at the designated acupuncture points. Each needle will be manually manipulated with lifting, thrusting, twirling, and rotating to elicit Deqi sensation (including soreness, numbness, distention, and heaviness). Needles will remain inserted for 30 minutes per session and manipulated three times, every 10 minutes. Acupuncture sessions will be conducted three times weekly over a six-week period.
