BACKGROUND: Postherpetic neuralgia (PHN) is a chronic neuropathic pain that results from alterations of the peripheral nervous system in areas affected by the herpes zoster virus. The symptoms include pain, paresthesia, dysesthesia, hyperalgesia, and allodynia. Despite the availability of pharmacological treatments to control these symptoms, no treatments are available to control the underlying pathophysiology responsible for this disabling condition. METHODS/DESIGN: Patients with herpes zoster who are at least 50 years old and have a pain score of 4 or higher on a visual analogue scale (VAS) will be recruited...

BACKGROUND: Around 30% of the population will experience herpes zoster (HZ), 10% of whom develop postherpetic neuralgia (PHN). Together, these illnesses produce a significant economic burden to the healthcare system. METHODS: Administrative healthcare data collected over the period of April 1(st) 1997 to March 31(st) 2014 were analyzed to determine the healthcare system burden of HZ using direct medical costs. Episodes of HZ were identified using international classification of disease (ICD) codes...

Introduction Trigeminal neuralgia (TN) is characterized by touch-evoked unilateral brief shock-like paroxysmal pain in one or more divisions of the trigeminal nerve. In addition to the paroxysmal pain, some patients also have continuous pain. TN is divided into classical TN (CTN) and secondary TN (STN). Etiology and pathophysiology Demyelination of primary sensory trigeminal afferents in the root entry zone is the predominant pathophysiological mechanism. Most likely, demyelination paves the way for generation of ectopic impulses and ephaptic crosstalk...

BACKGROUND: Patients with neuropathic pain (NeP) often receive combination therapy with multiple agents in the hopes of improving both pain and any comorbidities that may be present. While pregabalin is often recommended as a first-line treatment of NeP, few studies have examined the effects of concomitant medications on the efficacy of pregabalin. OBJECTIVE: To examine the effects of concomitant medications on the efficacy and safety of pregabalin for the treatment of NeP...

OBJECTIVES: Varicella-zoster virus reactivation can cause permanent histological changes in the central and peripheral nervous system. Neural inflammatory changes or damage to the dorsal root ganglia sensory nerve fibers during reactivation can lead to postherpetic neuralgia (PHN). For PHN of the first division of the fifth cranial nerve (ophthalmic division of the trigeminal ganglion), there is evidence of inflammatory change in the ganglion and adjacent ocular neural structures. First division trigeminal nerve PHN can prove to be difficult and sometimes even impossible to manage despite the use of a wide range of conservative measures, including anticonvulsant and antidepressant medication...

Inflammatory and neurotrophic factors are involved in postherpetic neuralgia (PHN), but the association of these factors in the cerebrospinal fluid (CSF) with the level of pain is poorly known. The present study aimed to examine the changes in neurotrophic and inflammatory factors in the CSF of patients with PHN and to study the correlation between these factors and the degree of pain. Fifty patients with PHN and 28 patients with hemifacial spasm (as controls) were recruited between May 2015 and March 2016...

When peripheral neuropathic pain affects a specific, clearly demarcated area of the body, it may be described as localized neuropathic pain (LNP). Examples include postherpetic neuralgia and painful diabetic neuropathy, as well as post-surgical and post-traumatic pain. These conditions may respond to topical treatment, i.e., pharmaceutical agents acting locally on the peripheral nervous system, and the topical route offers advantages over systemic administration. Notably, only a small fraction of the dose reaches the systemic circulation, thereby reducing the risk of systemic adverse effects, drug-drug interactions and overdose...

WHAT IS KNOWN AND OBJECTIVE: Gabapentin, extended-release gabapentin (gabapentin ER), and gabapentin enacarbil (GEn), play an important role in relieving pain associated with postherpetic neuralgia (PHN). Although previous systematic reviews have assessed the efficacy and safety of gabapentin formulations for PHN, they have failed to take formulation differences and dose differences into account. Aiming at assessing the efficacy and safety of different doses of gabapentin formulations for PHN, this study performed a systematical review and meta-analysis of randomized controlled trials (RCTs)...
