Abstract

BACKGROUND:

TNF blockers have demonstrated efficacy in inflammatory rheumatic diseases (IRDs). The drugs are associated with a moderate but definite risk of bacterial infection, but risk of viral infection is not clearly known.

OBJECTIVE:

To assess the risk of herpes zoster (HZ) reactivation in patients with rheumatoid arthritis (RA) receiving TNF blockers as compared with DMARDs.

METHODS:

A systematic search of literature up to March 2013 was performed, in MEDLINE, EMBASE, the Cochrane library and abstracts from the ACR and EULAR congresses from 2008 to 2011. Studies were included if they reported the incidence of HZ, respectively, in patients receiving anti-TNF and conventional DMARDs.

RESULTS:

The literature search identified 3446 articles and 88 congress abstracts; a manual search retrieved seven articles. Finally, 26 articles and nine abstracts were included; six articles and one abstract were of meta-analyses estimating the relative risk of HZ in patients with RA with a total follow-up of 163,077 patient-years. From the meta-analyses of data for seven registries, the pooled risk ratio for HZ with TNF blockers was 1.61 [95% CI 1.16-2.23] (P = 0.004). Proportions of severe HZ ranged from 4.9% to 20.9% with TNF-blockers and from 2.0% to 5.5% with conventional DMARDs, in the different registries.

CONCLUSIONS:

This meta-analysis revealed a significantly increased risk of HZ, up to 61%, in patients with IRD receiving TNF blockers. These data raise the issue of systematic prophylactic treatment with known history of HZ or vaccination without this history.
