Comparison of Varicella‐Zoster Virus–Specific Immunity of Patients with Diabetes Mellitus and Healthy Individuals

Abstract

Cell-mediated immunity (CMI) has been shown to be critical for the prevention and control of varicella-zoster virus (VZV)-related diseases. Because a large population-based study has revealed that diabetes mellitus is a risk factor for herpes zoster, we studied VZV-specific immune responses of patients with diabetes mellitus and compared them with those of healthy individuals. In this study, we found that patients with diabetes mellitus had significantly lower CMI to VZV than did healthy individuals. These results suggest that the increased risk for herpes zoster among patients with diabetes mellitus may be related to decreased VZV-specific CMI
