Patients with severe infections had a lower total number of CD19+B cells at baseline (as described previously; table 1) and tended to have lower CD5+B cells at month 1 (0.7/μL (range: 0.0–10.5) vs 1.9/μL (range: 0.0–108.3); p=0.053; figure 3A, B), while CD3+T cells did not differ between groups. The gene discussed is CD19; the disease is infection.
