ABSTRACT: Introduction
Several chronic underlying conditions (UCs) are known to be risk factors for developing herpes zoster (HZ) and to increase the severity of HZ and its risk of recurrence. The aim of this study was to investigate the incidence and recurrence of HZ in adult patients with one or multiple UCs.Methods
A retrospective cohort study based on claims data representing 13% of the statutory health insurance population from 2007 to 2018 in Germany was performed. Patients aged ≥ 18 years were included when at least one of the following UCs was diagnosed: asthma, chronic heart failure, chronic obstructive pulmonary disease (COPD), coronary heart disease (CHD), depression, diabetes mellitus type 1 or 2, and rheumatoid arthritis (RA). Exact matching was used to account for differences in the distribution of age and sex between the case and matched control cohorts. Multi-morbidity was considered in sensitivity analyses by analyzing patients with only one UC.Results
Patients with asthma, CHD, COPD, depression, and RA had, on average, a 30% increased risk of developing acute HZ compared to patients without any UC. RA was found to have the highest odds ratio among these conditions, varying from 1.37 to 1.57 for all age groups. Patients with depression also showed a high risk of developing HZ. Analysis of recurrence indicated that patients with at least one UC in the age groups 18-49 years and 50-59 years had the highest risk for a recurrent HZ. After experiencing a first recurrence, patients, regardless of age group, had a two- to threefold higher risk for a second recurrence.Conclusion
This study of representative claims data shows a higher HZ incidence and recurrence frequency in patients with UCs. These results provide relevant information for national health care guidelines and disease management programs.
