Sažetak
Information about the chimeric status of patients is of great importance in comparison of different conditioning and prophylactic regimens as well as for the post-BMT therapies. In some cases, mixed chimerism (MC) can also be predictive of relapse. Analysis of the short tandem repeats (STR) loci by polymerase chain reaction (PCR) is a choice method for this purpose. In this study we monitored 15 patients after BMT. Twelve of them underwent classical conditioning regimen while the remaining three patients were subjected to non-myeloablative conditioning (minitransplantation). Evaluation of chimerism was performed using five STR and one VNTR locus. Four additional loci were PCR amplified in cases of minitransplantation. Samples were analysed by electrophoresis in an ALFexpress sequencer. MC was detected in 7 cases out of which it was predictive of relapse for two patients, who suffered from ALL. The PCR-STR method proved to be a fast and relatively simple method, while the tested STR loci showed a high level of informativeness.
