Figure 3. Variations of IL-17 concentrations in BP serum from baseline until day 60 according to later BP relapse.

Serum concentrations of IL-17 were measured by ELISA at time of diagnosis and at day 60 in patients who were in remission (a) and patients who further relapsed (b). The subgroup of patients who expressed IL-17 at diagnosis (a) was analysed and divided into 2 subgroups: the first one for which IL-17 concentration was higher than 100 pg/ml at diagnosis (c) and the second one for which IL-17 concentration was higher than 0 but lower than 100 pg/ml (d).
