PG - 141-5 AB - The efficiency of restriction endonuclease in situ digestion (REISD) with Sau3A to analyze chimerism and residual disease (RD) has been tested before and after an allogenic bone marrow transplant (BMT) in an acute lymphoblastic leukemia (ALL) patient. The combined results obtained with REISD and FISH using the appropriate probes for detecting chromosome rearrangements have proven to be useful for the identification and quantification of both the hemopoietic chimerism achieved after BMT and the RD persistent in the patient. The sensitivity of REISD has been determined to be around 95%, i.e., similar to that obtained by FISH. REISD with Sau3A was particularly useful in the analysis of chimerism since this enzyme revealed the polymorphic status of constitutive heterochromatin in human chromosome 3 and thus allowed discrimination of cells derived from donor and recipient. The method itself seems promising since neither a donor/recipient sex mismatch nor a cytogenetic disease marker are needed for its application.
