Usefulness of Post-Transplant Hematopoietic Chimera Monitoring by Use of the Quantitative Fluorescence Polymerase Chain Reaction Method

Background

In the light of an increasing number of hematopoietic stem cell transplantations and more frequent use of reduced-intensity conditioning as preparative regimens for hematopoietic stem cell transplantation, post-transplant cell chimera monitoring is considered a necessity.

Methods

The quantitative fluorescence polymerase chain reaction method, along with the commercial AmpFSTR SGMPlus kit, was applied in research on hematopoietic chimeras.

Results

The total of 102 patients who had undergone allogenic transplantations were investigated. Chimerism monitoring was commenced on the seventh day after transplantation and lasted up to 12 years in some cases, according to the instituted schedule.

Conclusions

The kit has been shown to be fully sufficient for determining genetic profiles of recipients and donors and selecting informative markers. The method has been proven effective and satisfactory for assessing quantitative chimeras.
