BME analysis of allo-BMT patients is used to confirm engraftment and detect MC after transplant. With frequent monitoring, the detection of MC by BME analysis may alert clinicians to a high risk of relapse and allow early intervention with a rapid taper of immunosuppression or DLI therapy. In pancytopenic patients BME analysis can help differentiate relapse from drug toxicity or infection. Although many methods have been used for BME analysis, PCR amplification of STR loci is the choice of many clinical laboratories because it is informative, quantitative, relatively rapid, and sensitive. The sensitivity of BME analysis is dependent upon many factors that need to be optimized by the laboratory performing the analysis. Although BME analysis is complex, the clinical significance for allo-BMT patients warrants the effort to develop, validate, and perform BME analysis in support of the allo-BMT service.

A 34-year-old female was referred to our hospital for the evaluation of atypical lymphocytosis. Leukocyte count at diagnosis was 17,900/microl with 58% atypical lymphocytes having a convoluted nucleus and prominent nucleoli. Because the leukocyte count increased to 43,600/microl, the patient was treated with 2'deoxycoformycin followed by CHOP combination chemotherapy. However, both treatments failed to achieve remission. We planned an allogeneic bone marrow transplantation from an HLA-matched unrelated donor. The patient was treated with Ara-C and etoposide before conditioning to decrease the high leukemia burden. After administration of total body irradiation (12 Gy in six fractions) and cyclophosphamide (total dose of 120 mg/kg) unmanipulated marrow cells were infused. Under prevention of GVHD by CsA and short-term MTX, leukocyte engraft was prompt at day 16, and acute GVHD grade II was observed. Because 9.4% of residual recipient type T-cells was seen with STR analysis on day 22, we decreased the dose of Cs'A. After the occurrence of mild acute GVHD, the residual T-cell number decreased. The patient is still in complete remission for up to 22 months after BMT. We conclude that allogeneic SCT is effective for the treatment of T-PLL.

One severe aplastic anaemia case who presented autoimmune thyroid disease after allogeneic bone marrow transplantation (alloBMT) is described. A 19 year old Polish girl developed Graves' hyperthyroidisms 19 months after allogeneic BMT for severe aplastic anaemia (SAA) donated from her brother. Her serum was positive for thyroid stimulating antibody (TSAb) and anti-thyroid peroxidase autoantibodies (aTPO) while her brother remained euthyroid, seronegative for TSAb, and showed no clinical signs of thyroid pathology. The genetic studies of lymphocytes FISH (fluorescence in situ hybridization) and analysis of STR (short tandem repeated) fragments suggested, that lymphocytes responsible for hyperthyroidisms were of donor origin.

A 12-year-old male with pre-B-cell acute lymphoblastic leukemia with cryptic BCR/ABL rearrangement underwent sex-mismatched allogeneic bone marrow transplantation (allo-BMT). Contradictory results were provided by various chimerism analyses 3 months later. Y-chromosome-specific quantitative polymerase chain reaction and sex chromosome-specific interphase fluorescence in situ hybridization (i-FISH) showed complete donor chimerism. Analysis of autosomal short tandem repeats (A-STR), BCR/ABL i-FISH test, and X-STR haplotype indicated relapse. Metaphase-FISH and combined BCR/ABL and sex chromosome-specific i-FISH patterns revealed loss of the Y-chromosome and duplication of the X-chromosome in the host cells. Sex chromosome changes after allo-BMT can cause significant difficulties in chimerism analysis.
