- W3028937066 abstract "Objective To study the dynamic express of CD57 on T cell of PBMC and clinical significance in acute HIV infection.Methods Seventeen patients with acute HIV infection were enrolled study randomly diagnosed from 2006.11 to 2009.12 and 15 healthy donors as control group.The PBMCs from 1th,3th and 6th during acute infection were collected.The proportion of CD3+CD57+T lymphocytes,CD3+ CD8+CD57 +T lymphocytes and CD3 + CD4 + CD57 + T lymphocytes were evaluated by flow cytometric analysis with three or double color staining.The relationship between the proportion of CD57+ T phenotypes and virus load and CD4+T cells count was analyzed.Results The proportion of CD57+T lymphocytes in PMBC in 1th,3th and 6th during acute HIV acute was 15.24％ ±1.49％,13.51％ ±2.45％ and 14.65％ ±1.83％,respectively,and was higher than normal control group and the difference was significantly(P＜0.0001 ).The proportion of CD8+ CD57+T lymphocytes was 7.79％ ±2.10％ and 9.88％ ±2.36％ in 1th and 3th month during acute infection,respectively.The proportion of CD8+ CD57+T lymphocytes in 1th and 3th month during acute infection were positive relationship with virus load in corresponding time,and R2 was 0.3700 and 0.3768,and P value was 0.0096 and 0.0088,respectively.The proportion of CD8+CD57+T lymphocytes in the 1th and 3th month during acute infection was negative relationship with CD4+T lymphocytes count.The R2 was 0.3768 and 0.4235,and P value was 0.0215 and 0.0017,respectively.In 6 rapid progressors and 11 no rapid progressors on the 1th month after HIV infection,CD8+ CD57+T lymphocytes percentage was 11.20％±2.21％ and 6.16％ ±1.09％,respectively,and CD4+CD57+T lymphocytes percentage 2.79％ ±0.31％and 1.40％ ±0.30％,respectively.Both CD8+CD57+T and CD4+CD57+T in rapid progressors were higher than no rapid progressors,and P value was 0.0338 and 0.0106,respectively.Conclusion CD57+ T lymphocytes percentage in peripheral blood increase in acute HIV infection patients,in which the increasing CD8+CD57+T lymphocyte may mirror the dynamic of HIV replication and CD4+T cell count.The CD57 high express on T lymphocyte on the early HIV acute infection predicts rapid progression.Key words: HIV; CD57 antigen; CD8+T lymphocyte" @default.
