Abstract:Objective: This study aims to investigate the risk factors associated with postherpetic neuralgia (PHN) in patients with herpes zoster (HZ). Methods: A total of 458 HZ patients admitted to our hospital from January 2021 to April 2025 were selected and divided into a postherpetic neuralgia group (PHN = 155 cases) and a non-postherpetic neuralgia group (non-PHN = 303 cases) based on whether they developed neuralgia after herpes healing. Common clinical data were collected, and univariate and multivariate logistic regression analyses were conducted to identify independent risk factors for PHN in HZ patients. Results: Univariate logistic regression analysis revealed that age, herpes in special locations, duration of herpes zoster, visual analog scale (VAS) score, severity of skin lesions, glycated hemoglobin (HbA1c) level, and body temperature increase >1°C were statistically significant risk factors for PHN in HZ patients. Multivariate logistic regression analysis identified age, duration of herpes zoster, herpes in special locations, VAS score, severity of skin lesions, and body temperature increase >1°C as independent risk factors for PHN. Conclusion: Age, duration of herpes zoster, herpes in special locations, VAS score, severity of skin lesions, and body temperature increase >1°C are independent risk factors for PHN.
