Hypertension is regarded as a condition of mild inflammation and endothelial imbalance. The aim of the study was to evaluate serum concentrations of biomarkers of inflammation and endothelial function: tumour necrosis factor alpha (TNF-α), endothelin-1 (ET-1), and N-terminal fragment of pro-atrial natriuretic peptide (NTpro-ANP) in hypertensive and normotensive children.
We studied 63 children aged 13.56 ± 3.73 years, divided into two groups: a group with primary hypertension (n = 50) and a group with renal hypertension (n = 13). The control group consisted of 34 normotensive children aged 12.76 ± 3.96 years. Biomarkers were measured with ELISA tests.
ET-1 levels were significantly higher in primary hypertension (9.93 ± 1.73 pg/ml) and renal hypertension (10.77 ± 1.50 pg/ml) in comparison to controls (4.03 ± 0.97 pg/ml), (p < 0.001, p < 0.001, respectively). NT-pro ANP concentrations in primary hypertension (71.03 ± 10.02 pg/ml), and renal hypertension (84.78 ± 6.44 pg/ml) were significantly higher than in the control group (29.62 ± 5.56 pg/ml) (p < 0.001, p < 0.001, respectively). TNF-α concentrations in primary hypertension (8.36 ± 1.60 pg/ml) and renal hypertension (7.35 ± 0.93 pg/ml) significantly exceeded concentrations in controls (4.49 ± 0.93 pg/ml), (p < 0.001, p < 0.001, respectively). ET-1 and NT-pro ANP concentrations in renal hypertension significantly exceeded those in primary hypertension (p = 0.049, p < 0.001, respectively) while TNF-α levels in renal hypertension were significantly lower than in primary hypertension (p = 0.046).
The results of our study show that ET-1, NT-pro ANP, and TNF-a concentrations are increased in hypertension in children. Our investigation indicates significant importance of inflammation and endothelial involvement in hypertension in youth.
高血压被认为是一种轻度炎症和内皮失衡的状态。本研究旨在评估炎症和内皮功能的生物标志物在高血压和正常血压儿童中的血清浓度：肿瘤坏死因子-α（TNF-α）、内皮素-1（ET-1）和氨基末端脑钠肽前体（NTpro-ANP）。
我们研究了 63 名年龄为 13.56 ± 3.73 岁的儿童，分为两组：原发性高血压组（n = 50）和肾性高血压组（n = 13）。对照组由 34 名年龄为 12.76 ± 3.96 岁的正常血压儿童组成。生物标志物采用 ELISA 法检测。
原发性高血压组（9.93 ± 1.73 pg/ml）和肾性高血压组（10.77 ± 1.50 pg/ml）的 ET-1 水平明显高于对照组（4.03 ± 0.97 pg/ml）（p < 0.001，p < 0.001）。原发性高血压组（71.03 ± 10.02 pg/ml）和肾性高血压组（84.78 ± 6.44 pg/ml）的 NT-pro ANP 浓度明显高于对照组（29.62 ± 5.56 pg/ml）（p < 0.001，p < 0.001）。原发性高血压组（8.36 ± 1.60 pg/ml）和肾性高血压组（7.35 ± 0.93 pg/ml）的 TNF-α浓度明显高于对照组（4.49 ± 0.93 pg/ml）（p < 0.001，p < 0.001）。肾性高血压组的 ET-1 和 NT-pro ANP 浓度明显高于原发性高血压组（p = 0.049，p < 0.001），而肾性高血压组的 TNF-α水平明显低于原发性高血压组（p = 0.046）。
本研究结果表明，儿童高血压患者的 ET-1、NT-pro ANP 和 TNF-a 浓度升高。我们的研究表明，炎症和内皮参与在青少年高血压中具有重要意义。
