Predictive Value of Blood Glucose Coefficient of Variation for Prognoses in Patients with Diabetes Mellitus-Associated Herpes Zoster.

Herpes zoster (HZ) and diabetes mellitus (DM) are common diseases in middle-aged and older adults aged 50 years or more, and the prevalence of DM-associated HZ is gradually increasing. Several studies have confirmed that DM is a significant risk factor for postherpetic neuralgia (PHN). However, few studies have investigated the correlation between blood glucose-related indices and prognoses in patients with DM-associated HZ. The purpose of this study was to investigate the effect of blood glucose-related indices on the prognoses of these patients.
