An estimated one million individuals in the US are diagnosed with herpes zoster (HZ; shingles) each year. Approximately 20% of these patients will develop postherpetic neuralgia (PHN), a complex HZ complication characterized by neuropathic pain isolated to the dermatome that was affected by the HZ virus. PHN is debilitating, altering physical function and quality of life, and commonly affects vulnerable populations, including the elderly and the immunocompromised. Despite the availability of an immunization for HZ prevention and several approved HZ treatments, the incidence of PHN is increasing. Furthermore, management of the neuropathic pain associated with PHN is often suboptimal, and the use of available therapeutics may be complicated by adverse effects and complex, burdensome treatment regimens, as well as by patients' comorbidities and polypharmacy, which may lead to drug-drug interactions. Informed and comprehensive assessments of currently available pharmacological treatment options to achieve effective pain control in the primary care setting are needed. In this article, we discuss the situation in clinical practice, review currently recommended prevention and treatment options for PHN, and outline practical considerations for the management of this neuropathic pain syndrome, with a focus on optimal, individual-based treatment plans for use in the primary care setting.
据估计,美国每年有100万人被诊断患有带状疱疹(HZ;俗称“蛇缠腰”)。这些患者中约有20%会发展为带状疱疹后神经痛(PHN),这是一种复杂的HZ并发症,其特征是局限于HZ病毒感染的皮节的神经性疼痛。PHN使人虚弱,会改变身体功能和生活质量,并且通常影响包括老年人和免疫功能低下者在内的弱势群体。尽管有用于预防HZ的疫苗以及几种已获批准的HZ治疗方法,但PHN的发病率仍在上升。此外,与PHN相关的神经性疼痛的管理往往不尽人意,现有治疗方法的使用可能因不良反应、复杂且繁琐的治疗方案以及患者的合并症和多种药物联用而变得复杂,这可能导致药物相互作用。需要在初级保健环境中对当前可用的药物治疗选择进行明智且全面的评估,以实现有效的疼痛控制。在本文中,我们讨论临床实践中的情况,回顾目前推荐的PHN预防和治疗选择,并概述这种神经性疼痛综合征管理的实际注意事项,重点是用于初级保健环境的优化的、基于个体的治疗计划。
