Introduction. Antitumor necrosis factor-alpha (TNF-α) agents are widely used for treatment of rheumatic and dermatological diseases. We conducted the systematic review and meta-analysis to assess the prevalence of HBV reactivation among patients treated with anti-TNF-α. Methods and Findings. A comprehensive literature search of MEDLINE, Scopus, and ISI Web of Knowledge databases was conducted. From 21 studies included in the systematic review, 9 included patients with occult chronic HBV infection and 6 included patients with overt infection while 6 addressed both groups. Based on 10 studies eligible for meta-analysis we report pooled estimate of HBV reactivation of 4.2% (95% CI: 1.4-8.2%, I 2: 74.7%). The pooled prevalence of reactivation was 3.0% (95% CI: 0.6-7.2, I 2: 77.1%) for patients with occult infection, and 15.4% (95% CI: 1.2-41.2%, I 2: 79.9%) for overt infection. The prevalence of reactivation was 3.9% (95% CI: 1.1-8.4%, I 2: 51.1%) for treatment with etanercept and 4.6% (95% CI: 0.5-12.5%, I 2: 28.7%) for adalimumab. For subgroup of patients without any antiviral prophylaxis the pooled reactivation was 4.0% (95% CI: 1.2-8.3%, I 2: 75.6%). Conclusion. Although HBV reactivation rate is relatively low in patients treated with anti-TNF-α for rheumatic and dermatological conditions, the antiviral prophylaxis would be recommended in patients with overt chronic HBV infection. © 2014 Fabrizio Cantini et al.

Abstract
Introduction. Antitumor necrosis factor-alpha (TNF-α) agents are widely used for treatment of rheumatic and dermatological diseases. We conducted the systematic review and meta-analysis to assess the prevalence of HBV reactivation among patients treated with anti-TNF-α. Methods and Findings. A comprehensive literature search of MEDLINE, Scopus, and ISI Web of Knowledge databases was conducted. From 21 studies included in the systematic review, 9 included patients with occult chronic HBV infection and 6 included patients with overt infection while 6 addressed both groups. Based on 10 studies eligible for meta-analysis we report pooled estimate of HBV reactivation of 4.2% (95% CI: 1.4-8.2%, I 2: 74.7%). The pooled prevalence of reactivation was 3.0% (95% CI: 0.6-7.2, I 2: 77.1%) for patients with occult infection, and 15.4% (95% CI: 1.2-41.2%, I 2: 79.9%) for overt infection. The prevalence of reactivation was 3.9% (95% CI: 1.1-8.4%, I 2: 51.1%) for treatment with etanercept and 4.6% (95% CI: 0.5-12.5%, I 2: 28.7%) for adalimumab. For subgroup of patients without any antiviral prophylaxis the pooled reactivation was 4.0% (95% CI: 1.2-8.3%, I 2: 75.6%). Conclusion. Although HBV reactivation rate is relatively low in patients treated with anti-TNF-α for rheumatic and dermatological conditions, the antiviral prophylaxis would be recommended in patients with overt chronic HBV infection. © 2014 Fabrizio Cantini et al.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
