Abstract:
Objective:To explore the plasma chemokines expressions and related clinical implication in patients with Stanford type A aortic dissection (AD).
Methods:We retrospectively analyzed the data of 65 patients with Stanford type A aortic dissection, hypertensive patients and 11 healthy subjects admitted in our department from October 2013 to December 2014, they were divided into four groups: NH-CON group (11 healthy subjects), H-AD group (29 AD patients with hypertension), NH-AD group (21 AD patients without hypertension), and H-CON group (14 hypertension patients). Four plasma samples from AD patients and 4 plasma samples from healthy subjects were collected randomly with random numbers table, and the levels of different chemokines were examined by protein array analysis. Then, plasma levels of chemokines including macrophage inflammatory protein 1β(MIP-1β), epithelial neutrophil activating peptide 78(ENA-78), interleukin 16(IL-16), interferon inducible protein 10(IP-10) and FMS-like tyrosine kinase 3(Flt-3) ligand were analyzed by luminex. Pearson analysis was used to determine the correlations between the chemokines and serum C reactive protein (CRP) levels.
Results:Plasma levels of MIP-1β(34.0(29.3, 47.2) ng/L vs. 51.0(28.2, 80.7) ng/L, P<0.05) and ENA-78(110.5(59.1, 161.4) ng/L vs. 475.7(299.3, 837.3) ng/L, P<0.05) were significantly lower in H-AD group, while plasma IL-16 level was significantly higher in H-AD group(54.7(16.3, 187.8) ng/L vs. 17.5(11.9, 20.8) ng/L, P<0.05) than in H-CON group. Plasma levels of MIP-1β(48.3(26.4, 62.1) ng/L, P<0.05) were significantly lower in H-AD patients than in NH-AD patients. Plasma level of ENA-78 was significantly lower in NH-AD group than in NH-CON group (95.0(58.0, 155.0) ng/L vs. 257.7(85.2, 397.8) ng/L, P<0.05). The levels of IP-10 and Flt-3 ligand were similar among the 4 groups (all P>0.05). Pearson analysis showed that there were no correlation between MIP-1β(r2=0.01, P>0.05), ENA-78(r2=0.02, P>0.05), IL-16(r2=0.02, P>0.05), IP-10(r2=0.00, P>0.05), Flt-3 ligand(r2=0.02, P>0.05) and CRP levels in patients with Stanford type A aortic dissection.
Conclusions:Lower plasma levels of MIP-1β and ENA-78 and higher plasma levels of IL-16 may associate with the occurrence and development of type A aortic dissection, but their concentrations are not correlated with serum CRP levels. There is no significant change on plasma levels of IP-10 and Flt-3 in the Stanford type A aortic dissection patients.
