Thicker Carotid Intima Media Thickness in Children with Monocyte Chemoattractant Protein-1: A-2138T and A-2464G Mutation

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.

BACKGROUND :Ischemic stroke is the most common stroke comprising 70-80% of all cases. Carotid intima-media thickness (CIMT) is associated with the occurrence of stroke in older age and adults. Patients with type 2 diabetes mellitus tend to develop a thickening of intima-media carotid artery. Simvastatins inhibit further atherothrombotic process. OBJECTIVE : To analyze the effect of simvastatin for CIMT in ischemic stroke patient with type 2 diabetes mellitus. METHOD : This study was a Randomized Pretest-Posttest Design and conducted at the Hospital Inpatient Ward Dr. Kariadi and Ketileng Semarang from January to December 2014 for all first ischemic stroke patients with Type 2 Diabetes Mellitus. Subjects were divided into groups of 26 controls and 28 patients treated groups. Treatment group were given simvastatin 20 mg each daily for 24 weeks in 28 subjects with a history of acute ischemic stroke and type 2 Diabetes mellitus. Examine the CIMT at the 1st week and 24th week. The normality of the data were tested using Shapiro Wilk and the differences analyzed by using Paired t-test and independent t test. RESULT : There was a significant differences between delta carotid intima-media thickness on administration of simvastatin for ischemic stroke patients with type 2 diabetes mellitus (p=0,008). CONCLUSION : Simvastatin significantly decreases CIMT on ischemic stroke patients with type 2 diabetes mellitus. Keyword : simvastatin, ischemic stroke, carotid intima-media thickness, type 2 diabetes mellitus LATAR BELAKANG :Stroke iskemik memiliki angka insidensi terbanyak yaitu 70-80% kasus stroke. Ketebalan Intima-media karotis berhubungan dengan terjadinyastroke pada usia tua.Pasien dengan Diabetes mellitus tipe 2 memiliki kemungkinan yang lebih besar mengalami penebalan intima-media carotis. Simvatatin menghambat proses aterotrombosis. TUJUAN :Untuk menganalisis pengaruh simvastatin terhadap ketebalan intima-media karotis pada pasien stroke iskemik dengan diabetes mellitus tipe 2. METODE :Penelitian ini adalah dengan Randomized Pretest-Posttest Design dan telah dilakukan di Rawat Jalan RSUP dr. Kariadi dan poli saraf rawat jalan RSUD Kota Semarang mulai Januari sampai dengan Desember 2014 untuk semua pasien stroke iskemik pertama kali dengan diabetes mellitus tipe 2. Subjek dibagi menjadi kelompok kontrol 26 pasien dan kelompok perlakuan 28 pasien. Kelompok perlakuan diberi simvastatin 20 mg sehari selama 24 minggu pada 28 subjek stroke iskemik dengan diabetes mellitus tipe 2. Pemeriksaan ketebalan intima-media karotis dilakukan pada minggu ke-1 dan minggu ke-24. Data kemudian di uji normalitasnya menggunakan Saphiro wilk, lalu di analisis menggunakan uji beda paired t testdan independent t test. HASIL : Kelompok perlakuan didapatkan penurunan ketebalan tunika intima arteri karotis (0,395 + 0,46; p=0,514), KESIMPULAN : Pemberian simvastatin menurunkan ketebalan intima-media karotis secara bermakna pada pasien stroke iskemik dengan diabetes mellitus tipe 2.

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.
