Abstract:
OBJECTIVETo explore the ratio of lymphocyte subsets in peripheral blood of patients with aplastic anemia (AA) and patients with hypoplastic myelodysplastic syndrome (hypo-MDS) patients and to evaluate their significance.
METHODSThe clinical data of 181 cases of AA and 111 cases of hypo-MDS from January 2008 to December 2014 were collected from Blood Diseases Hospital of Chinese academy of medical sciences, and then the differences of lymphocyte subsets and its effect in 2 groups were analyzed.
RESULTSCD4/CD8ratio, proportion of CD3cells and its subsets CD3CD4/CD3CD8cells in hypo-MDS group were not significant different from AA group (P>0.05). the proportion of CD3CD16/CD56NK cells and CD3CD57T-LGL cells in hypo-MDS group was significantly higher than that in AA group (P<0.05, P<0.01), but CD19B lymphocyte percentage in hypo-MDS patients was lower than that in AA patients (P<0.05). After dividing group according to CD4/CD8ratio, the ratios of CD3CD16/CD56NK cells and CD3/CD57T-LGL cells were higher only in normal CD4/CD8ratio group of hypo-MDS patients than those in AA patients, while the ratio of B lymphocytes was significant different in inverted CD4/CD8ratio group between hypo-MDS and AA patients. The CD19B lymphocyte ratio in hypo-MDS patients was significantly lower than that in AA patients (P<0.05). As well, the levels of erythrocytes and platelets in peripheral blood between hypo-MDS and AA patients only in normal CD4/CD8ratio group were significantly different, while the significant difference of WBC count and reticulocyte ratio were observed in high CD4/CD8ratio and non-inverted CD4/CD8ratio groups, respectively; the significant difference of bone marrow blast ratio and muture monocyte ratio was found in high CD4/CD8ratio group.
CONCLUSIONThe changes of lymphocyte subsets can be used as an reference indicator for differential diagnosis of hypo-MDS and AA. The comparative analysis of patients with these 2 kinds of diseases after dividing into subgroups according to ratio of CD4/CD8cells is beneficial to differentiat diagnosis.
