Risk of hepatitis B reactivation in HBsAg−/HBcAb+ patients after biologic or JAK inhibitor therapy for rheumatoid arthritis: A meta‐analysis

ABSTRACT: Abstract

Background

The risk of hepatitis B virus (HBV) reactivation after biologic and targeted synthetic disease‐modifying antirheumatic drugs (b/tsDMARDs) therapy in patients with rheumatoid arthritis (RA) combined with HBsAg–/HBcAb+ is still inconsistent.

Methods

We conducted a systematic review of existing databases from 1977 to August 22, 2021. Studies of RA patients combined with HBsAg−/HBcAb +, treated with b/tsDMARDs and the reported number of HBV reactivation were included.

Results

We included 26 studies of 2252 HBsAg−/HBcAb+ RA patients treated with b/tsDMARDs. The pooled HBV reactivation rate was 2.0% (95% confidence interval [CI]: 0.01−0.04; I2 = 66%, p < .01). In the subgroup analysis, the HBV reactivation rate of rituximab (RTX), abatacept, and inhibitors of Janus kinase (JAK), interleukin‐6 (IL‐6), and tumor necrosis factor‐α (TNF‐α) were 9.0% (95% CI: 0.04−0.15; I2 = 61%, p = .03), 6.0% (95% CI: 0.01−0.13; I2 = 40%, p = .19), 1.0% (95% CI: 0.00−0.03; I2 = 41%, p = .19), 0.0% (95% CI: 0.00−0.02; I2 = 0%, p = .43), 0.0% (95% CI: 0.00−0.01; I2 = 0%, p = .87), respectively. While HBsAb‐ patients have a significant risk of reactivation (odds ratio [OR] = 4.56, 95% CI = 2.45−8.48; I2 = 7%, p = .37), low HBsAb+ group also display a significant risk of reactivation (OR = 5.45, 95% CI: 1.35−21.94; I2 = 0%, p = .46).

Conclusions

This meta‐analysis demonstrates the highest potential risk of HBV reactivation in HBsAg−/HBcAb+ RA patients receiving RTX treatment, especially HBsAb− patients. Our study furthers the understanding of the prophylactic use of anti‐HBV drugs in such patients. However, it is relative safety to use the inhibitors of IL‐6, TNF‐α, and JAK in these patients. Abatacept is second to rituximab (RTX) at high risk of HBV reactivation in RA patients combined with HBsAg−/HBcAb + . Prophylactic use of anti‐HBV drugs should also be considered in HBsAg−/HBcAb+ RA patients treated with abatacept if they have multiple risk factors.

Project description:IntroductionJanus kinase (JAK) inhibitors are a class of targeted therapies for rheumatoid arthritis (RA) with established clinical efficacy. However, little is known about their efficacy compared with each other. This network meta-analysis (NMA) estimated the comparative efficacy of JAK inhibitors currently approved for RA.MethodsA targeted literature review was conducted for phase III randomized controlled trials (RCTs) evaluating the efficacy of three approved JAK inhibitors (tofacitinib, baricitinib, and upadacitinib) as monotherapy or combination therapy among patients with moderate-to-severe RA who had inadequate response to conventional synthetic disease-modifying antirheumatic drugs (csDMARD-IR). Using Bayesian NMA, American College of Rheumatology (ACR) 20/50/70 responses and clinical remission (defined as DAS28-CRP < 2.6) were evaluated separately at 12 and 24 weeks.ResultsEleven RCTs were identified and included in the NMA. All JAK inhibitors demonstrated significantly better efficacy than csDMARD. Among combination therapies, upadacitinib 15 mg had the highest 12-week ACR50 responses (median [95% credible interval]: 43.4% [33.4%, 54.5%]), followed by tofacitinib 5 mg (38.7% [28.6%, 49.8%]), baricitinib 2 mg (37.1% [25.0%, 50.6%]), and baricitinib 4 mg (36.7%, [27.2%, 47.0%]). Similar results were observed for ACR20/70 and at week 24. Upadacitinib 15 mg + csDMARD was also found to have the highest clinical remission rates at week 12 (29.8% [16.9%, 47.0%]), followed by tofacitinib 5 mg (24.3%, [12.7%, 40.2%]), baricitinib 4 mg (22.8%, [11.8%, 37.5%]), and baricitinib 2 mg (20.1%, [8.6%, 37.4%]). Similar results were seen at week 24. Among monotherapies, upadacitinib had a higher ACR50 response (38.5% [25.3%, 53.2%]) than tofacitinib (30.4% [18.3%, 45.5%]). The differences in efficacy measures were not statistically significant between the JAK inhibitors.ConclusionsThe NMA found that upadacitinib 15 mg once daily had numerically higher efficacy in terms of ACR response and clinical remission among approved JAK combination therapies and monotherapies for csDMARD-IR patients with RA.
