Serum levels of anti-type VII collagen AAb (COL7 Ab) in patients with relapse (n = 24) (mean value at time of relapse 7.8 U/mL vs. mean value at baseline 3.6 U/mL) (A) and in patients with ongoing remission (n = 32) (B). Mean delay between diagnosis and relapse was 270 days. Among the 24 patients with relapse, 10 patients were identified with positive ELISA score of anti-type VII collagen AAb at time of relapse (mean value at time of relapse 15.4 U/mL) (C) and 14 patients experienced relapse without presenting anti-type VII collagen AAb (D). Comparison was made either between baseline and relapse or between baseline and day 270 for patients with ongoing remission (**P < 0.01, ***P < 0.001).
