Sažetak
We report an effective follow-up of the establishment of bone-marrow function after an allogeneic bone-marrow transplantation in a patient with acute lymphoblastic leukemia, by means of a suitable genetic marker, phosphoglucomutase-1 (EC 5.4.2.2) isoenzyme. A patient with acute lymphoblastic leukemia received allogeneic bone-marrow graft from a sibling who was of the same sex and blood group, HLA-identical, and mixed-lymphocyte-culture nonreactive. To monitor the bone-marrow engraftment and the type and degree of chimerism established, we used a genetic marker, the phosphoglucomutase-1 isoenzyme system, to reveal the difference between the bone-marrow host and donor. We did phosphoglucomutase-1 isoenzyme subtyping of the host's and donor's erythrocytes before transplantation, and isoenzyme phenotyping of the host's erythrocytes during a year after transplantation. Establishment of bone-marrow graft function, a period of temporary mixed chimerism with a population of both host's and donor's erythrocytes, a period of the exclusive presence of donor's erythrocytes, and the resumed appearance of host's erythrocytes after eight months, with no signs of relapse of leukemia, were all observed by analysis of phenotypes. These isoenzymes served as a significant and practical genetic marker, which could be successfully used in studies on bone-marrow transplantation.
