ABSTRACT
Objective: Treatment options for patients with rheumatoid arthritis on maintenance hemodialysis with an inadequate response to biologic agents have not been reported. In this report, we describe two patients who achieved remission after treatment with peficitinib.Methods: Two 69- and 85-year-old patients with rheumatoid arthritis on maintenance hemodialysis were previously treated with biologics and started on peficitinib 100 mg/day after the secondary failure of biologics.Discussion: In the two cases presented here, rheumatoid arthritis was almost in remission and there were no adverse events, although the patients were switched to peficitinib after secondary failure of the biologic agents. Among Janus kinase inhibitors, peficitinib has the lowest renal excretion; therefore, its administration in patients on dialysis is not contraindicated according to the package insert in Japan. The use of biologic agents in patients on hemodialysis has been reported to be associated with a high incidence of infections; therefore, care should be taken to avoid infections when administering Janus kinase inhibitors.Conclusion: Janus kinase inhibitors with low renal excretion, such as peficitinib, may be effective in patients with rheumatoid arthritis on maintenance hemodialysis who have an inadequate response to biologic agents.
ABSTRACT
OBJECTIVE：To systematically evaluate the efficacy and safety of pe ficitinib for treating rheumatoid arthritis （RA），and to provide evidence-based reference for the clinical treatment of RA. METHODS ：Retrieved from PubMed ，Embase， The Cochrane Library ，CJFD，VIP and Wanfang database during from their establishment to September 2019，randomized controlled trials （RCTs）about the efficacy and safety of Peficitinib （trial group ）versus placebo （control group ）in the treatment of RA were collected. The risk of bias assessment tool provided in Cochrane System Evaluator Manual 5.1.0 was used to evaluate the quality after data extracted from clinical studies which met the inclusion criteria. Meta-analysis of the efficacy [the proportion of patients who met the American College of Rheumatology 20％ improvement criteria （ACR20），ACR50，ACR70，the proportion of the patients with 28 joint disease activity index ＜2.6 calculated by erythrocyte sedimentation rate （DAS28-ESR＜2.6），the proportion of patients with 28 joint disease activity index ＜2.6 calculated by C-reactive protein （DAS28-CRP＜2.6），etc.] and safety（incidence of total ADR ）was performed by using Stata 16 statistical software. RESULTS ：Totally 5 RCTs were included ， 药学。E-mail：hyl3160131@163.com 5.11），P＜0.001]，150 mg[RR＝3.52，95％CI（1.78，6.96），P＜ 0.001]}，ACR70{total [RR ＝2.51，95％CI（1.52，4.14），P＜0.001]，100 mg[RR＝3.50，95％CI（1.62，7.58），P＝0.001]，150 mg [RR＝4.59，95％CI（1.47，14.30），P＝0.009]}，DAS28-ESR＜2.6{total [RR ＝4.83，95％CI（3.20，7.28），P＜0.001]，100 mg[RR＝ 5.37，95％CI（2.68，10.77），P＜0.001]，150 mg[RR＝7.44，95％CI（3.78，14.65），P＜0.001]} and DAS 28-CRP＜2.6{total [RR ＝3.41， 95％CI（2.65，4.39），P＜0.001]，100 mg[RR＝4.00，95％CI（2.67，5.99），P＜0.001]，150 mg[RR＝4.45，95％CI（2.99，6.63），P＜ 0.001]} in trial group were significantly higher than control group ，with statistical significance. In term of safety ，there was no statistical significance in the incidence of total ADR [RR ＝1.05，95％ CI（0.94，1.16），P＝0.395] between 2 groups. CONCLUSIONS：For the treatment of RA ，100 mg or 150 mg peficitinib once per day is superior to placebo in terms of ACR 20， ACR50 and ACR 70，DAS28-ESR＜2.6，DAS28-CRP＜2.6； the adverse events are mild and tolerable and it may be a new treatment option for RA.
