原发性肾病综合征患者外周围血淋巴细胞亚群、白介素2及其高亲和力受体表达的研究

Lymphocyte subpopulation, interleukin-2 and high affinity interleukin-2 receptor expression in primary nephrotic syndrome]

OBJECTIVE: To understand the cellular immune response during relapse and remission stage in primary nephrotic syndrome (PNS). METHODS: We applied the radioligand binding assay (RBA), the bioactivity measurement of IL-2, and monoclonal antibody sensitized red blood cell method to evaluate the expression of IL-2R, the production of IL-2 and T lymphocyte subsets of PBMC from 22 patients suffering from PNS, 17 patients with PNS in remission, and 25 normal subjects matched age and sex. RESULTS: CD3, CD4, CD8, IL-2, IL-2R in relapse were significantly lower than those in control (P < 0.05); all above except CD8 in remission patients were significantly higher than those in relapse, but lower than those in control (P < 0.05). CONCLUSION: This study suggested that the cell mediated immunity (CMI) during acute nephrotic phase decreased; the deficiency of CMI of PNS in remission improved a lot when compared with the acute phase, but still not recovered completely; the deficiency of CMI with PNS in remission might be one of the causes of easily recurring of PNS.
