简要总结
This randomized clinical trial investigates the possible beneficial effect of autologous fat grafting on postherpetic neuralgia.
详细描述
Herpes Zoster (HZ), is a condition caused by Varicella-Zoster virus (VZV), The disease is caused by reactivation of a latent VZV-infection in the sensory ganglia.
Clinically the condition is characterized by a painful, unilateral, vesicular rash. Pain is the most prominent symptom in around 90% of patients. In 10% of patients, this pain remains and becomes chronic.
Post-herpetic neuralgia is a chronic pain syndrome that occurs after the dermal manifestation disappears. Treatment is complex and mainly topical or systemic. For many patients, this is not sufficient and they live with constant pain.
Autologous fat grafting has shown promise in treating several different painful conditions such as post-mastectomy pain syndrome, painful scars, etc. Our previous pilot study (NCT03584061) investigating the effect of autologous fat grafting on PHN, showed a marked reduction in pain with half of the patients being pain-free after the procedure.
The aim of this study is to test the hypothesis that autologous fat grafting is more effective than a sham operation in treating PHN.

结局指标
主要结局
Neuropathic pain [LEVEL OF PAIN]
时间窗: 6 months
Neuropathic Pain Symptom inventory (NPSI), Questionnaire. NPSI consists of 12 items in total: 10 items investigates differential symptoms descriptors and 2 items evaluate spontaneous and paroxysmal spontaneous pain. The tool evaluates mean pain intensity in the last 24h in a verbal numeric scale from zero (no pain) to 10 (worst imaginable pain). Total pain intensity score may be calculated by the sum of the 10 descriptors. The descriptors are: Burning, Squeezing, Pressure, Electric Shocks, Stabbing, Provoked by brushing. Provoked by pressure, Evoked by cold stimulation, Pins and needles, Tingling.
