Herpes zoster (HZ) is an acute herpetic skin disease caused by the reactivation of the varicella-zoster virus (VZV) latent in the sensory ganglia. Postherpetic neuralgia (PHN) often occurs after herpes zoster heals and persists for a long time. At present, clinically anticonvulsants (such as gabapentin, pregabalin) and antidepressants (such as amitriptyline) are clinically first-line drugs for the treatment of PHN, which are not usually effective to treat PHN well, as well as to alleviate patients' bad mental symptoms. Esketamine, as a well-known N-methyl-D-aspartate receptor inhibitor, has both analgesic and antidepressant effects with extremely few incidence of respiratory depression, delirium, hallucinations, nausea and vomiting. Therefore, we hypothesize that esketamine could relieve PHN and Anxiety and depression-like symptoms symptoms in patients with PHN. This study intended to compare the efficacy of pregabalin, amitriptyline combined with esketamine therapy and pregabalin combined with amitriptyline therapy for alleviating PHN, and to further explore the feasibility and safety of esketamine in the treatment of PHN as well as underlying the mechanism of esketamine on the PHN.
Evaluation of the efficacy of LX9211 compared to placebo in reducing pain related to postherpetic neuralgia over an 11 week assessment period.
Postherpetic neuralgia (PHN) has a high incidence rate and severely impact on quality of life and health care costs, interfering with physical, emotional and social functioning of affected patients. Current therapeutic options for PHN mainly include analgetic and local anaesthesia for selective nerve blockade. Nevertheless, the efficacy of analgetic is always limited by inevitable side effects, in which patients have poor compliance. Moreover, for some most suffering patients, the control of pain is often unsatisfactory despite the administration of complex combinations. As a non-pharmarceutical therapy, acupuncture is widely use for a wide range of pain conditions. Thus, it might be an alternative treatment for PHN. The aim of this multicenter randomized controlled trial is to investigate the efficacy and safety of electroacupuncture therapy in patients with postherpetic neuralgia.
The investigators designed the multicenter randomized parallel controlled clinical trial of electroacupuncture on PHN which is rigorously designed and have an appropriate sample size, aiming to evaluate the efficacy and safety of electroacupuncture in pain relieving and pain removing in the treatment of patients with PHN.
This randomized clinical study will be carried out on 72 patients admitted to the pain clinic in Tanta University Hospitals with post-herpetic neuralgia. Cases presenting to the Pain Clinic with acute pain due to postherpetic neuralgia in thoracic and/or lumbar dermatomes with numerical rating scale (NRS) of 6 or more and they will be randomly divided, using the closed envelop method, into three equal groups. Group A (24 patients): Patients will be subjected to the routine medical treatment of post herpetic neuralgia as controls (Pregabalin, acyclovir, and paracetamol) and sham erector spinae plane block Group B (24 patients): Patients will be subjected to erector spinae block by bupivacaine (2 - 2.5 mg/kg, with a maximum of 175 mg/dose) together with medical treatment. Group C (24 patients): Patients that will subjected to erector spinae block by bupivacaine (2 - 2.5 mg/kg, with a maximum of 175 mg/dose with the addition of MgSO4 (equivalent to 100 mg)) together with medical treatment. Primary outcome will be the efficacy of pain relief Secondary outcome will be the frequency of pain and the consumption of analgesics.
The purpose of this study is to investigate the incidence of intravascular injection during trigeminal nerve blocks.
In this study, the investigators aim to investigate the preventive efficacy of prophylactic oral duloxetine during acute herpes zoster on postherpetic neuralgia and its safety.
This randomized clinical trial investigates the possible beneficial effect of autologous fat grafting on postherpetic neuralgia.
The aim of the present study is to compare contralateral oblique view with the lateral view for fluoroscopic guided mid-thoracic epidural assess.
