Abstract

OBJECTIVE:

To assess the immunogenicity and safety of vaccination against seasonal influenza in psoriatic arthritis (PsA) patients treated with secukinumab versus healthy controls (HC).
METHODS:

PsA patients administered secukinumab for ≥3 months and HC received the Sanofi Pasteur vaccine composed of 3 antigens (H3N3, H1N1, and B) and underwent clinical and laboratory assessments on the day of vaccination and 4-6 weeks later. Immunogenicity of the vaccine was evaluated by hemagglutination inhibition assay against those 3 antigens. Responders to each antigen were defined by a 4-fold increase in the antigen titer or by seroconversion in patients whose baseline level was <1/40.
RESULTS:

Thirty-two consecutive PsA patients treated with secukinumab for ≥3 months comprised the study group, 10 of whom received concomitant conventional synthetic disease-modifying drugs, mostly methotrexate. There were 17 age- and gender-matched HC (median age 48.5 years, 6 females). The geometric mean titers of each antigen increased significantly in both groups. The number of responders in each group was similar for H3N2 and H1N1, and significantly higher for B/Brisbane in the PsA group. The proportion of patients with a seroprotective level (a titer >1/40) was high and similar in both groups. There was no correlation between the response rate and age, gender, or selected parameters of disease activity (tender/swollen joint counts, Leeds enthesitis index, physician and patient global assessment, psoriasis area severity index, and C-reactive protein). No disease exacerbation was observed following the vaccination. No serious adverse effects were observed in both groups during the study period.
CONCLUSION:

Secukinumab treatment does not affect the humoral response to influenza vaccine of patients with PsA.
