At the month 1 assessment, compared to infection-free patients, patients with infectious events had lower CD3+ T cells (1093 vs. 498 cells/μL, respectively, p = 0.05), lower CD8+ T cells (363 vs. 128 cells/μL, respectively, p = 0.0313) and lower CD19+ B cells (234 vs. 33 cells/μL, respectively, p = 0.0009). Here, CD19 is linked to infection.
