CD27+ memory B cells remain depleted long after treatment. Scatter plot of FACS analysis of PBMCs from patients and controls obtained before (T0; A) and 4 wk after (T1; B) influenza vaccination. Time after treatment = months since last rituximab administration, calculated at T0. CD27+ memory B cells were still depleted long after treatment, without any significant linear correlation between time after treatment and CD27+ memory B cell levels, as shown by the continuous lines. Spearman’s rank correlation coefficient test (ρ) was used to correlate CD27+ memory B cell data and time after treatment.
