I finished the 4th cycle of rev/dex and am now starting number 5. The good thing about this is that I am now on standard dose of dex. Thank goodness. My IgA is at 468 mg/dL now, too. The lowest yet. IgG: 273 mg/dL and IgM: 36. I remember when my IgM was too low to measure and my IgA was 4,625 mg/dL. Dr. H told me that I am having the best response, with the least side effects of all the pts in the Rev/dex EAP at their clinic.
