Obesity is a multifactor disease with a very complicated etiology. Genetic factors play an important role in the development of primary obesity. They may be responsible for up to 40% of causes leading to obesity. There are a great number of genes affecting food intake and energy expenditure. Serious consequences accompanying obesity, e.g., type 2 diabetes and lipid abnormalities may be caused by increased level of proinflammatory cytokines, such as IL-1, IL-6, and TNF. It is possible that polymorphisms located in cytokine genes affect the level of protein expression. It is known that IL-6 plays a role in lipid metabolism and energy expenditure. The polymorphism found in point 174 (G174C) of a promoter region of IL-6 gene affects the level of interleukin-6 expression and, consequently, may lead to obesity and correlated conditions. 相似文献

Subclinical cerebral infarcts (SCI) have been increasingly shown to cause a significant clinical impact. However, there are limited data available on Asian patients. The objectives of this study were to determine the prevalence of SCI in ischaemic stroke patients seen in the Hospital Universiti Kebangsaan Malaysia (HUKM) and to identify its associated risk factors. We evaluated the brain computed tomography (CT) evidence of subclinical infarcts in ischaemic stroke patients. The patients were selected from those who were on regular follow up in the neurology clinic following an ischaemic stroke. The risk factors associated with subclinical infarct were documented. The brain CTs were done during acute admission and reviewed for SCI. Sixty-one patients were enrolled in this study. Twenty-two (36.1%) out of the 61 patients had SCI. The risk factors for SCI in our study were hypertension (OR 14.16 CI 2.04-97.89), diabetes mellitus (OR 12.48; CI 1.95-79.77) and leukoaraiosis (OR 28.39; CI 2.33-284.16). Subclinical cerebral infarcts were present in about one third of our ischaemic stroke patients. This finding is higher than in previous studies done on Caucasians. Hypertension, diabetes mellitus and leukoaraiosis independently predict SCI. 相似文献

Background Vascular smooth muscle cells (VSMCs) can express heme-oxygenase (HO), a rate-limiting enzyme in the degradation of heme to bilirubin, ferritin and carbon monoxide (CO). VSMC-derived CO can suppress VSMC proliferation and may serve as an antiproliferation factor. The promoter region of HO-1 shows a polymorphism with different (GT)n repeats that has been reported to differently induce gene expression. The objective of this study was to examine the effect of this variation on the occurrence of restenosis after in-stent treatment in patients with coronary artery disease. Methods Candidates who underwent coronary stent implantation were genotyped for the HO-1 promoter polymorphism using polymerase chain reaction (PCR) and automated DNA capillary sequencer. Serum levels of IL-6 and C-reactive protein (CRP) were obtained at baseline, 24 hours and 48 hours after stenting. The primary end point for the study was angiographic evidence of in-stent restenosis at 6 months. All parameters for evaluation of restenosis were analysed by quantitatve computer-assisted angiographic analysis (QCA). Results One hundred and eighty-seven patients who underwent coronary stent implantation were studied of whom 27.8% showed ≥50% restenosis after 6 months. The distribution of (GT)n repeats of all patients in the promoter region of HO-1 genotype ranged from 22 to 42, with (GT)25 and (GT)32 being the two most common alleles. The allelic repeats were divided into the short class (S) with 29 (GT)n, the middle class (M) with 30-37 (GT)n and the long class (L) with 38 (GT)n. There was no significant difference in the restenosis between the genotype groups or between post operation levels of inflammation markers, but carriers of the S allele (n=120) had 33.3% lower baseline IL-6 compared with non-S carriers (n=67, P=0.0008). Conclusions Although no association was observed between the HO-1 promoter polymorphism and coronary in-stent restenosis following the stent procedure, the association with plasma IL-6 levels suggests that HO-1 S allele might protect from the atherosclerotic inflammatory process. 相似文献

Increasing evidence suggests that inflammation plays an important role in the development of both cardiovascular and cerebrovascular events. Recently C-reactive protein (CRP) levels have been reported to be a prognostic factor for cerebrovascular and cardiovascular events. The main objective of the study was to evaluate the prognostic value of CRP levels in a first ever ischaemic stroke at one month. All ischaemic stroke patients who were admitted to Hospital Universiti Kebangsaan Malaysia (HUKM) between May 2002 and July 2002 were eligible for the study. CRP levels were taken within 72 hours after an acute ischaemic stroke. The functional ability was assessed using the Barthel Index (BI) after one month of stroke. During the study period 84 patients were admitted to HUKM with the diagnosis of ischaemic stroke; 49 patients were enrolled and 35 were excluded. Twenty-nine patients (59.2%) had elevated CRP levels (median 1.64+/-3.07 mg/dL, range 0.06 to 16.21 mg/dL). Elevated CRP levels were found to be a predictor of severe functional disability (BI<5) and were also associated with larger infarcts. In conclusion, elevated CRP levels are associated with poorer functional outcome and predict a larger infarct size. 相似文献
