Background
The study attempts to assess the relationship between chimerism analysis using polymerase chain reaction of short tandem repeat (STR) and the incidence of chronic graft versus host disease (GvHD) as well as survival.Methods
The retrospective cohort included all patients who received allo-HSCT between 2005 to 2013. Data collected by day 흍 were reviewed in terms of the incidence of chronic GvHD and survival. Chimerism was evaluated for whole blood, T-cell and PMN cells on days 15, 30 and 60, respectively using polymerase chain reaction of short tandem repeat (STR).Results
Forty (69%) patients developed chronic GvHD, 11 (19%) relapsed and 22 (39.7%) died during the study. There was a significant relationship between chronic GvHD and chimerism analysis including whole blood on day 60 (P=0.001), PMN on day 60 (p= 0.05) and T-cell on days 15 (p=0.028), 30(p=0.01) and 60 (p=0.004). Patients with chronic GvHD showed a long-term survival as compared with those without chronic GvHD (P=0.0013).Conclusion
Conducting continuous analysis of chimerism provides an opportunity to initiate immediate measures to prevent complications.Keywords:
