Multicenter Study Observational Study
Impact of Herpes Zoster and Post-Herpetic Neuralgia on Health-Related Quality of Life in Japanese Adults Aged 60 Years or Older: Results from a Prospective, Observational Cohort Study.
Herpes zoster (HZ) and its most frequent complication, post-herpetic neuralgia (PHN), have been shown to considerably impact quality of life (QoL). This has not yet been demonstrated in Japan. ⋯ HZ impaired QoL in daily activity performance and emotional and physical functioning. The negative impact on QoL was more prevalent in patients with a longer PHN duration compared with HZ without PHN. ClinicalTrials.gov identifier: NCT01873365.
