I wonder how long it takes before peripheral B-cells start showing up after a single 1000mg infusion for maintenance therapy. There's quite a bit of variation from person to person, but I have no idea how large the variance might be. If folks share this info we might learn something new.
In my case, B-cells showed up 8 months after the first 4-round treatment, then 10 months after the 1st maintenance infusion. It's been 11 months since my last infusion and the B-cells are still at 0%. Although some docs follow a 6-month regimen, mine prefer to wait until B-cells show up.
