Considerations for discontinuing IgG-RT.
| • Consider pausing IgG-RT 9–12 months after discontinuation of B cell-depleting therapy |
| • Monitor for endogenous recovery of CD19+ B cells, CD20+ B cells, IgG, IgM, and IgA |
| • Able to maintain IgG ≥400 mg/dL for three consecutive months off IgG-RT without evidence of recurrent bacterial infections |
| • Protective vaccine responses checked 3–4 months after IgG-RT discontinuation |
