Brief Summary
Exploratory study of anti-pneumococcal immune response in patients with Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) immunized according to new vaccine recommendations (i.e. with a combined vaccine schedule (13-valent conjugate pneumococcal vaccine -PCV13- followed by a 23-valent non-conjugate pneumococcal vaccine -PPV23- 8 weeks later).

Outcome Measures
Primary Outcomes (1)
Anti-pneumococcal immunity after combined anti-pneumococcal immunization
Proportion of responder patients at V1 (12-weeks after PCV13 injection) to at least 6 of the 10 shared serotypes (i.e. 3, 4, 6B, 7F, 9V, 14, 18C, 19A, 19F and 23F) included both in PCV13 and PPV23. A serotype is considered positive if the ELISA immunoglobulins G (IgG) antibody titter shows a two-fold increase from baseline (V0) to V1 and is ≥ 1 μg/ml
visit V1 (12 to 16 weeks after V0 (Day 0))
Secondary Outcomes (5)
To assess serotype 3, 4, 6B, 7F, 9V, 14, 18C, 19 A, 19F and 23F-specific immune responses after vaccination
visit V0 (Day 0), visit V1 (12 to 16 weeks after V0) and visit V2 (48 to 56 weeks after V0).
To assess serotype coverage increase after PPV23 injection
visit V0 (Day 0), visit V1 (12 to 16 weeks after V0) and visit V2 (48 to 56 weeks after V0).
For the following serotypes (4, 6B, 9V, 14, 18C, 19F and 23F), to assess the proportion of ELISA-responding patients who also show in vitro opsonophagocytic antibody activity.
visit V0 (Day 0), visit V1(12 to 16 weeks after V0) and visit V2 (48 to 56 weeks after V0).
Change Outcome Measures-To assess the sustainability and evolution over time of the vaccine-induced immune response (ELISA and OPA)
visit V2 (48 to 56 weeks after V0).
Composite Outcome Measures - To identify epidemiologic, clinic and biologic predictive factors that may influence vaccine-induced immune response.
visit V0 (Day 0), visit V1 (12 to 16 weeks after V0) and visit V2 (48 to 56 weeks after V0).
