Introduction: Atopic dermatitis (AD) patients have an increased risk of herpes zoster (HZ). The relationship of dupilumab, tralokinumab, upadacitinib, and abrocitinib to HZ incidence in AD patients remains unclear.
Aim: To evaluate and compare the incidence and risk of HZ among patients with moderate to severe atopic dermatitis treated with advanced systemic therapies.
Material and methods: Systematic searches were conducted in Ovid Medline and Embase. The primary outcome was incidence of HZ in patients with moderate to severe AD receiving placebo or the aforementioned treatments. A frequentist random-effects NMA was conducted with odds ratio.
Results: Our search identified 16 trials comprising 10,689 patients. Upadacitinib was associated with a dose-dependent increase in the incidence of HZ compared to placebo (OR = 2.55 [1.09, 5.95] and (OR = 4.29 [1.89, 9.74], respectively) and compared to various dupilumab doses (OR = 4.48 [1.29, 15.57], 3.61 [1.28, 10.18] and 7.54 [2.21, 25.68], 6.09 [2.24, 16.52], respectively). Upadacitinib 30 mg was associated with a higher incidence of HZ when compared to upadacitinib 15 mg (OR = 1.68 [1.19, 2.38]). Abrocitinib 200 mg was associated with a higher increase in HZ compared to placebo (OR = 3.34 [1.34, 8.31]). According to SUCRA ranks, both JAK-1 inhibitors had a higher cumulative incidence of HZ compared to dupilumab.
Conclusions: JAK-1 inhibitors are associated with a significantly higher incidence of HZ compared to dupilumab and placebo. Our results suggest that recombinant HZ vaccination should be highly considered for all adult patients prior to starting oral JAK-1 inhibitors.
