(A) Mean anti-factor H (FH) antibody titers, and (B) Free FH during remission in patients with or without subsequent relapse. Relapses were seen in 12 of 182 (A) and 10 of 44 (B) patients. Generalized estimating equations approach was used on log transformed data. In patients with relapse, the last anti-FH titer and free FH was estimated at median of 1 (0.7–2) months and 5 (2–6.9) months before relapse, respectively. Anti-FH antibody titers ≥1,330 AU/ml or free FH ≤ 440 mg/l predict later relapse.
