Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Antibody titres against S. Pneumonia and H. influenzae type b (in *g/mL) vaccine before and after vaccinations. Titres will be interpreted and classified in responder or non-responder. | — |
Secondary
| Measure | Time frame |
|---|---|
| - Immunoglobulin levels and subclass. - Lymphocyte subsets (number of B cells and memory-B cells, CD3, CD4, CD8 and NK cells). - Production of IFN-gamma by CD4+ cells. This will be measured in order to investigate if cellular mediated immune responses are intact after rituximab treatment. - Cytokines and genetic factors (for example BAFF, CXCL13, APRIL) influencing B cell development and survival will be measured in order to determine if there is a correlation between specific cytokines/genetic factors and the observed B-cell depletion/reconstitution. - Serum rituximab levels. | — |
