My husband still had mixed chimerism 6 months after transplant. Team was very concerned about the CD4 line which was very laggardly. Our transplant doctor recommended a DLI and our donor was gracious enough to give us a second gift of life.
Chimerism went to 100% within two months after the DLI (accompanied by GVHD, but it is well managed). Over a year later he remains in full remission. Graft vs. leukemia for the win.
Best of luck to you Janet.
