C反应蛋白(CRP)是全身性炎症和心血管疾病风险增加的标志物。经常锻炼可以降低CRP。载脂蛋白E(apo E)有3种常见的基因型变异体E2/3、3/3和3/4,它们调节脂质代谢,并可能具有其他代谢生理作用,包括基因型影响CRP水平的一些证据。我们评估了117名(男性= 51,女性= 66)健康成年人的空腹血清CRP,他们自愿参加了为期6个月的有氧运动计划。71名受试者(男性= 31名,女性= 40名)接受了训练前和训练后的测量。在基线和随访时,3组中的受试者数量大致相等:2/3,n = 3/3和20; 3/3,n = 41和26; 3/4,n = 43和25。基线时,CRP水平因载脂蛋白E基因型而异:E2/3、3/3和3/4受试者的平均值± SD分别为2.84 ± 2.18、2.59 ± 2.34和1.90 ± 2.13 mg/L(3/4 vs 2/3,P <0.05)。女性CRP水平高于男性(3.14 ± 2.49vs2.12 ± 2.13mg/L,P <0.006)。在整个队列(2.68 ± 2.38 vs 2.52 ± 2.48 mg/L)或任何apo E基因型组中,运动均未影响CRP,并且在基线时观察到的apo E基因型效应在训练后持续存在。在一项以白色为主的研究队列中,apo E3/3中的CRP高于3/4受试者,女性中的CRP高于男性,但经过6个月的标准有氧运动训练(国家组织为降低心血管疾病风险而推广的体积和更高强度)后,CRP保持不变。载脂蛋白E基因型如何影响CRP尚不清楚。
C-reactive protein (CRP) is a marker for systemic inflammation and increased cardiovascular disease risk. Regular exercise may decrease CRP. Apolipoprotein E (apo E) has 3 common genotype variants—E2/3, 3/3, and 3/4—that modulate lipid metabolism and may have other metabolic physiologic roles, including some evidence that the genotype affects CRP levels. We assessed fasting serum CRP in 117 (male = 51, female = 66) healthy adults who volunteered for a 6-month aerobic exercise program. Both pre- and posttraining measurements were available in 71 (male = 31, female = 40) subjects. At baseline and follow-up, the numbers of subjects in the 3 groups were approximately equal: 2/3, n = 33 and 20; 3/3, n = 41 and 26; and 3/4, n = 43 and 25. At baseline, CRP levels differed by apo E genotype: means ± SD were 2.84 ± 2.18, 2.59 ± 2.34, and 1.90 ± 2.13 mg/L for E2/3, 3/3, and 3/4 subjects, respectively (3/4 vs 2/3, P < .05). In women, CRP was higher than that in men (3.14 ± 2.49 vs 2.12 ± 2.13 mg/L, P < .006). Exercise failed to affect CRP in the entire cohort (2.68 ± 2.38 vs 2.52 ± 2.48 mg/L) or in any apo E genotype group, and the apo E genotype effect observed at baseline persisted after training. In a largely white study cohort, CRP is higher in apo E3/3 than in 3/4 subjects and in women compared with men, but remains unchanged by 6 months of standard aerobic exercise training of the volume and higher intensity promoted by national organizations to reduce cardiovascular disease risk. How apo E genotype affects CRP is not known.
