Carotid intima media thickness (CIMT) is clearly associated with atherosclerosis. Studies in ischemic stroke patients reveal that there is a significant association between CIMT with monocyte chemoattractant protein-1 (MCP-1) and osteopontin (OPN) promoter polymorphism. This research aims to explain the effect of MCP-1 and OPN promoter polymorphism toward CIMT changes identified in Javanese Indonesian children. Subjects were 54 children: 27 were from parents with ischemic stroke (cases), and 27 were from healthy parents (controlled). The CIMT was examined by utilizing high resolution B-mode ultrasound. Physical examination and genotyping analysis of MCP-1 promoter were conducted by employing PCR method. Research results indicate that two polymorphisms were obtained, that is, A-2138T and G-2464A, respectively. A-2138T polymorphism was found in 5% of case children and in 14.3% of controlled children. G-2464A polymorphism was found in 5% of case children. CIMT of case children was significantly different from that of controlled children (0.61±0.012 mm versus,0.52±0.015 mm,P=0.021). Subjects with MCP-1 promoter polymorphism have 1.471 times higher tendency to have thicker CIMT than subjects with no polymorphism in MCP1 promoter. OPN promoter T-66G was also studied but it did not indicate occurrence of polymorphism in samples.

Abstract Background: People with hypertension display an inflammatory pattern that includes increased plasma concentrations of monocyte chemoattractant protein 1 (MCP-1) and C-reactive protein (CRP) and enhanced expression of tissue factor (TF) mRNA in blood monocytes. Methods: In this study, we investigated the relationship between CRP concentrations and TF and MCP-1 mRNA expression in unstimulated and lipopolysaccharide (LPS)-stimulated monocytes isolated from hypertensives with or without an increase in carotid intima-media thickness (IMT). We also investigated the expression of TF and MCP-1 mRNA and MCP-1 protein after in vitro addition of CRP to monocytes. We measured CRP (by immunonephelometry) and monocyte expression of TF and MCP-1 (by real-time PCR) in 80 untreated hypertensive patients without clinical cardiovascular disease (CVD) or additional risk factors for CVD compared with 41 controls. Based on IMT measured by carotid Doppler ultrasonography, patients were classified into the categories of normal (≤1 mm) or abnormal (>1 mm). TF and MCP-1 mRNA and MCP-1 protein (by Western blotting) were measured after in vitro addition of CRP to monocytes from 10 randomized controls as well as 10 hypertensives with IMT ≤1 mm and 10 with IMT >1 mm. Results: CRP and TF and MCP-1 mRNA concentrations were significantly higher in IMT >1 mm hypertensives vs those with IMT ≤1 mm and controls. CRP had no effect on monocyte TF mRNA from either hypertensives or controls. CRP-stimulated monocytes from hypertensives, however, showed increased MCP-1 mRNA and protein expression compared with controls and LPS-stimulated cells. Conclusions: Our findings suggest that the inflammatory response of blood monocytes plays an important role in the development of atherosclerosis and hypertension.
