Abstract:
Objective To study the dynamic changes of soluble interleukin 2 recepter (sIL 2R) level and lymphocyte subsets over clinical course, the relationship between them and biochemical parameters of renal function, and to explore the role of the disturbance of celluar immune function in the pathogenesis of hemorrhagic fever with renal syndrome (HFRS). Methods The level of sIL 2R in sera was detected by double antibody sandwich ELISA method. The percentages of lymphocyte subsets were measured by flow cytometry. Results The level of sIL 2R in patients with HFRS increased significantly in febrile phase, reached its peak in hypotensive and oliguric phase and then decreased gradually in diuretic phase but still higher than that of normal in convalescent phase with values being (463.06?157.02) pmol/ml, (636.85?270.36) pmol/ml, (287.75?118.74) pmol/ml and (191.75?55.60) pmol/ml in different stages, respectively ( P 0.05). The percentage of CD3 +,CD4 + cells decreased significantly while the percentage of CD3 +, CD8 + cells increased significantly, which resulted in the decrease or reverse of CD4 +/CD8 + ratio in febrile phase. These changes were most obvious in hypotensive and oliguric phase, returned gradually in diuretic phase, but still abnormal in convalescent phase ( P
