This real-world study by Kim, et al. found no significant relationship between continued JAK inhibitor therapy in patients with IMIDs and the risk of subsequent recurrent HZ reactivation. They also found no significant difference in the number of days patients were treated for HZ in the JAK inhibitor continuation and discontinuation groups.
Korean Health insurance claims data of patients ≥20 years of age with RA or ulcerative colitis were gathered from January 2007 to February 2021 by HIRA, which covers the entire population of South Korea.
