白细胞介素-10和肿瘤坏死因子-α与高血压肾损害的相关性研究

目的 探讨肿瘤坏死因子-α(TNF-α)和白细胞介素-10(IL-10)在高血压肾损害患者中的变化及其相关性.方法 将73例原发性高血压患者(原发性高血压组)根据其尿蛋白排泄率不同又分为2个亚组:单纯高血压组37例,高血压肾损害组36例;采用放射免疫法检测血清TNF-α、IL-10浓度.同期选择30名健康体检者作为正常对照组.结果 原发性高血压组TNF-α高于正常对照组(2.91±0.94)μg/L与(0.98±0.35)μg/L,P＜0.01],其中高血压肾损害组TNF-α高于单纯高血压组(3.75±0.88)μg/L与(1.87±0.58)μg/L,P＜0.01].原发性高血压组IL-10低于正常对照组(19.2±5.8)μg/L与(28.6±5.7)μg/L,P＜0.01],其中高血压肾损害组IL-10又低于单纯高血压组(15.4±4.3)μg/L与(22.5±5.9)μg/L,P＜0.01].原发性高血压组TNF-α、IL-10与尿蛋白排泄率有相关性(r=0.703,P＜0.001 ;r=-0.613,P＜0.001),而与血压水平无相关性.结论 高血压肾损害患者TNF-α升高,IL-10水平降低,细胞因子系统的失衡可能参与了高血压肾损害的进展.

Abstract：

Objective To investigate the changes of the serum levels of necrosis alpha (TNF-o)and interleukin 10( IL-10 )in patients with hypertensive renal damage,and to study the correlation of TNF-α and IL-10 with the hypertensive renal damage. Methods Seventy three patients with primary hypertension were divided into two groups according to their urinary albumin excretion rate(UAER): simple hypertensive group( n = 37 ),hypertensive renal damage group(n =36). TNF-α and IL-10 were measured using radioimmune assay. Thirty normotensive healthy persons were selected as normotensive control group. Results TNF-α were significantly higher and IL-10 significantly lower in patients with essential hypertension than those in normotensive control group(TNF-α: 2.91 ±0.94]μg/L vs 0.98 ±0.35]μg/L,P＜0. 05;IL-10: 19.2 ±5.8]μg/L vs 28.6±5. 7] μg/L,P ＜0. 01 ) ,and in patients with hypertension,those with renal damage had higher TNF-α and lower IL-10 than those without( TNF-α: 3.75 ± 0. 88 ] μg/L vs 1.87 ± 0. 58 ] μg/L, P ＜ 0. 01; IL-10: 15. 4 ± 4. 3 ]μg/L vs 22. 5 ± 5.9 ] μg/L, P ＜ 0. 01 ), with statistically significant difference between groups ( P ＜ 0. 01 ).TN F-α and IL- 10 were found to have correlations with UAER ( r = 0. 703, P ＜ 0. 001; r = - 0. 613, P ＜ 0. 001 ),but no correlation with the level of blood pressure. Conclusion TNF-α increased and IL-10 decreased significantly in patients with hypertensive renal damage, which indicates that the imbalanced cytokine network may play a role in the pathological mechanisms of hypertensive renal damage.
