Evaluation of Pneumococcal and Tetanus Vaccine Responses in Patients with Rheumatoid Arthritis Receiving Baricitinib: Results from a Long-Term Extension Trial Substudy
Arthritis Res Ther. 2019 Apr 18;21(1):102
Approximately two thirds of long-term BARI treated patients achieved satisfactory humoral and functional responses to 13-serotype pneumococcal conjugate vaccine (PCV-13), whereas tetanus toxoid vaccine (TTV) responses were less robust. Both RA management guidelines and recommendations suggest vaccinating patients with RA against pneumococcal disease with PCV-13 and PPSV-23. The inhibition of the JAK mediated signal transduction pathways in RA treatment could diminish vaccine responses. Given the...
