Patients with AD at elevated risk of herpes zoster infection

Researchers have found in a new study that Patients with atopic dermatitis (AD) have an elevated risk of herpes zoster infection compared with those without atopic dermatitis (AD), regardless of age or treatment status.
The study has been published in the journal Dermatitis.
This nationwide study of 28,677 participants with atopic dermatitis (AD) found a higher risk of herpes zoster infection in patients with AD than in the control group. The risk of herpes zoster infection remained elevated in all gender-, age-, and treatment-stratified models, and did not differ between patients with AD treated with or without systemic medication.
In the wake of the emerging development of biologics in atopic dermatitis (AD), herpes zoster (HZ) infection has been reported as a treatment-related adverse event.
This study aims at investigating the association between atopic dermatitis (AD) and herpes zoster (HZ), and the risk factors within.
28,677 participants with AD from the Taiwan National Health Insurance Research Database 2000–2015 were enrolled. Risk of HZ infection was compared in the study cohort (with AD) and the control cohort (without AD). Further analyses were conducted in gender-, age-, and treatment strategy-stratified subgroups.
Results:
Significantly higher adjusted hazard ratios (aHRs) of herpes zoster (HZ) infection were revealed in atopic dermatitis (AD) patients (aHR = 2.303, P < 0.001), and remained this trend in gender- and age-stratified models. All AD groups, irrespective of the treatment type, had higher aHRs (AD without systemic treatment: aHR = 2.356, P < 0.001; AD with systemic treatment: aHR = 2.182, P < 0.001) compared with those without AD. However, no differences in HZ risk were shown between each treatment type.
Risk of herpes zoster (HZ) infection in AD is higher irrespective of treatment type. Considering that AD per se increases susceptibility to HZ infection, the administration of biologics requires careful considerations.
