Filter by:The goal of this clinical trial is to evaluate safety and efficacy of percutaneous peripheral nerve stimulation in patients with postherpetic neuralgia. The main questions it aims to answer are: 1. The efficacy of percutaneous peripheral nerve stimulation in patients with postherpetic neuralgia 2. The safety of percutaneous peripheral nerve stimulation in patients with postherpetic neuralgia Participants are going to undergo procedure that implant peripheral nerve stimulation electrode produced by Jiangsu CED Medtech Co., Ltd. Then the subjects, whose VAS scores decrease more 30% than baseline level, are classified into two groups randomly. One of the group receiving active stimulation called trial group and another receiving placebo stimulation called control group. All subjects are required to make their own subjects' pain diary to record VSA score before and after implantation until at the end of follow-up. Also, participants are asked to report use of analgesic medications, number of awakenings and adverse events. Researchers will compare pain scores between the two groups to see if peripheral nerve stimulation is effective to patients with postherpetic neuralgia.
1. The correlations of serum vitamin D level, serum calcium level and osteoporosis degree with disease severity, treatment response, incidence of Post-Herpes zoster(PHN) and disease prognosis in Herpes zoster(HZ) patients were studied. 2. To investigate the role of inflammation-related factors and immune-related factors in the occurrence and development of HZ mediated by low vitamin D level.
This is a prospective, multicenter observational study evaluating the efficacy of ganglion stimulation (medical device) in cases of post-herpetic neuropathy. This study introduces recent methods of phenotypic stratification of postherpetic neuropathy into the field of interventional pain therapy. The aim is to identify which clinical expression of this diverse pathology can derive the greatest benefits from an otherwise effective but expensive therapy such as ganglion stimulation. The study protocol includes the application of a common clinical practice, already in use for several years at the promoting center and participating centers (as well as internationally scientifically codified). It is supported by an innovative stratification of clinical expression (phenotype of the disease), recently introduced in the literature. The study aims to identify, through careful clinical evaluation, predictive indices of the greatest success in invasive ganglion stimulation therapy, a treatment associated with significant system costs and considerable inconvenience for the patient. The results of the experimentation will allow the codification of evaluative clinical pathways to predict a higher success index in certain clinical expressions of postherpetic neuropathy compared to others. This will help reduce the costs of implant trials and enable defining the real objective of the proposed therapy in consultation with the patient.
Postherpetic neuralgia (PHN) is the most frequent complication of herpes zoster(HZ) and is defined as pain persisting for >1month after the healing of herpetic skin lesion or pain persisting for > 3 months following the onset of HZ. PHN manifests as spontaneous throbbing, stabbing, or burning, usually accompanied by various abnormal sensory symptoms , which affect 5-20% of patients with HZ. Due to the lack of accurate and objective auxiliary examination tools, it is difficult for diagnosis and treatment of PHN. As a non-invasive examination method, infrared thermal imaging (IRT) can play a role in the diagnosis and treatment of neuropathic pain by objectively reflecting the changes and distribution characteristics of human body surface temperature. However, there are few studies on the relationship between clinical phenotype and thermal infrared image temperature changes in PHN patients, and the relationship between the thermal pattern of skin temperature and the duration of disease and treatment progress in PHN patients has not been fully elucidated. This study was conducted to investigate the relationship of thermal imaging data with the duration of the disease, clinical phenotype, treatment effect, in order to explore the role of infrared thermal imaging in the diagnosis and treatment of PHN. Methods：all PHN patients will included. At each visit, a pain NRS score was performed, and clinical phenotypes were tested and labeled, including: allodynia, numbness, itching, heat sensation, cold sensation, and the most painful area(MPA). Infrared thermal imaging was performed, the Average Relative Temperature (ART) within the affected area and the contralateral area was compared. The relationship between the temperature change and duration of the disease, clinical phenotype, treatment effect was assessed.
This is a single-center, randomized, single-dose, active-controlled study in healthy male and female subjects. The study will enroll subjects to evaluate the PK of 3 dose strengths (50 mg, 100 mg and 200 mg) of GTX-101 compared to Subcutaneous injection in healthy adult subjects. Blood samples for PK assessments will be collect at specified time points. Safety assessments will also be performed throughout the study.
This is a Phase II, international multicenter, double-blind, placebo-controlled, crossover study to assess the efficacy of SR419 in PHN subjects.
Recently, the use of pulsed radiofrequency has increased in many chronic pain conditions, including trigeminal neuralgia, chronic spinal pain, musculoskeletal pain, and it was recently used effectively for postherpetic neuralgia. Transforaminal epidural steroid injection has been proven in previous studies to provide effective analgesia for cases of herpes zoster-related pain. We hypothesize that the combined use of pulsed RF and steroid injection applied to the DRG may achieve better outcomes than the use of epidural steroid injection alone.
