T-cell–mediated immune response to pneumococcal conjugate vaccine (PCV-13) and tetanus toxoid vaccine in patients with moderate-to-severe psoriasis during tofacitinib treatment - 12/05/18
Abstract |
Background |
Psoriasis is often treated with immunomodulatory therapies that can affect the immune response to common antigens. Tofacitinib is an oral Janus kinase inhibitor.
Objective |
To characterize the effect of long-term exposure to tofacitinib 10 mg twice daily on T-cell function in psoriasis patients.
Methods |
Patients completing at least 3 months' continuous treatment with tofacitinib 10 mg twice daily were vaccinated with T-cell–dependent vaccines (monovalent tetanus toxoid and 13-valent pneumococcal conjugate [PCV-13]). Patients were assessed at baseline (before vaccination) and then again 4 weeks after vaccination. For PCV-13, we evaluated serotype-specific, opsonophagocytic antibody responses, and for tetanus toxoid, we evaluated humoral responses.
Results |
Among 60 patients who completed the study, the geometric mean fold rise from baseline for the 13 PCV serotypes at 4 weeks postvaccination varied from 8.3 (serotype 3) to 101.9 (serotype 6A). Similar results were observed for patients with and without lymphopenia at baseline. For tetanus toxoid, 51 (88%) patients had ≥2-fold and 35 (60%) patients had ≥4-fold rise in antibody concentration.
Limitations |
There was no placebo control.
Conclusion |
Most psoriasis patients who receive tofacitinib can mount satisfactory T-cell–dependent responses to PCV-13 and tetanus vaccines.
