Abstract:
Objective To explore the phenotypic characteristics of T lymphocyte subsets in the peripheral blood (PB) of Patients with rheumatoid arthritis.Methods forty-seven patients with ankylosing spondylitis (AS) and 36 health control were selected as our subjects.The patients were divided into definite Diagnosis AS group and potential AS group according to symptom and X-ray,flow cytometry was applied to measure T lymphocyte subsets and HLA-B27 of peripheral blood.At the same time,the levels of ESR,CRP and IgA were also measured.The correlation between T lymphocyte subsets and CRP HLA-B27,IgA level was analyzed.Results There was no significant difference between The definite diagnosis AS patients and healthy controls regarding of the percentages of CD3 + cells in peripheral blood,However the percentage of CD4 + cells in definite diagnosis AS patients was significantly increased than that of healthy controls (P ＜ 0.05).The ratio of CD4 +/CD8 + cells was 3.80 ± 0.28 in AS patients,higher than that of potential AS patients.T lymphocyte subsets were showed an increase tendency as the increase the level of CRP,IgA.Conclusion Lower CD8 + cell and higher CD4 + cell were showed in the peripheral blood of AS patients,which was correlated with the disease activity and suggesting T cells might be involved in the pathogenesis process of AS.Meanwhile our data indicated that the immune response might be a susceptible factor of AS and early detection of T lymphocyte subsets might provide a diagnosis and treatment basis for diagnosis of AS.Therefore the disorder of T lymphocyte subsets might play an important role in the development of rheumatoid arthritis.
