Association of vitamin D receptor gene BsmI (A>G) and FokI (C>T) polymorphism in gestational diabetes among Saudi Women.

OBJECTIVE: Vitamin D receptor (VDR) gene polymorphism have a role in diabetes mellitus pathogenesis. Present study was conducted to determine VDR gene variants among Saudi gestational diabetics (GDM) in Madina, KSA. METHODS: This cross sectional study was conducted on 112 GDM patients and 218 normal healthy control. Age, body mass index and blood pressure levels were recorded. Serum triglycerides (mg/dl), total cholesterol, HDL-cholesterol, LDL-cholesterol, fasting blood glucose FBG and post-prandial blood glucose PPBG were estimated. Extracted DNA template was amplified by PCR reaction and genotyped for single nucleotide polymorphism of BsmI and FokI by restriction fragment length polymorphism-PCR (RFLP-PCR) analysis. RESULTS: FBG and PPBG levels in GDM patients were significantly elevated by +48.6% and +50%, respectively (P=0.005). Serum triglycerides, total cholesterol and LDL-cholesterol (mg/dl) levels in GDM patients were elevated significantly by +40.5% (P=0.005), +16% (P=0.01) and +30.8% (P=0.005), respectively. Serum HDL-cholesterol (mg/dl) showed significant decline by -10.5%. FokI VDR genotypes showed association with PPBG (P=0.05) among GDM patients. The Ff, FF and ff genotype percentage among GDM patients was 48.2%, 30.4% and 21.4%, respectively. FokI (F and f) and BsmI (B and b) alleles frequency showed no significant difference between GDM patients and control. Percentage BsmI and FokI total homozygous and heterozygous variants among GDM was 45.5% and 81.4%, respectively. CONCLUSION: VDR BsmI and FokI polymorphic marker not associated with Saudi GDM.

Biochemical and C-reactive protein alterations in myocardial infarction periodontitis patients.

Periodontitis (PD) is a risk factor for acute myocardial infarction (AMI). C-reactive protein (CRP) is elevated in PD. The aim of this study was to investigate biochemical alterations among AMI with PD. Thirty non-AMI (25 non-PD and only 5 PD) and 30 AMI (13 PD and 17 non-PD) patients were participated. Serum CRP, tumor necrosis factor alpha (TNF-α), total cholesterol, low-density lipoprotein cholesterol, protein carbonyl (PC) contents, soluble vascular cell adhesion molecule-1 (sVCAM-1), adiponectin, creatine kinase, resistin, catalase and superoxide dismutase (SOD) levels were measured. AMI-PD elicited significant differences in percentage hypertension, diabetes, serum creatine kinase, cholesterol and low-density lipoprotein cholesterol. CRP among AMI-PD and non-AMI-PD was increased by 73.4% and 31.3%, respectively. The level of PC contents was increased significantly among AMI-PD and non-AMI-PD by 47.62% and 33.3%, respectively. Catalase and SOD levels were significantly decreased in AMI-PD by 33.7% and 34.1%, respectively; however, their levels among non-AMI-PD were significantly increased by 35.7% and 28%, respectively. TNF-α, sVCAM-1 and resistin levels among AMI-PD were increased by 134.3%, 68.8% and 25.5%, respectively; however, TNF-α and sVCAM-1 levels among non-AMI-PD were increased significantly by 21.4% and 29.4%, respectively. Adiponectin level produced insignificant changes. PD prevalence among AMI associated with elevated serum CRP, PC contents, sVCAM-1, TNF-α and resistin levels concurrent with declines in SOD and catalase enzymes. In conclusion, among nondiabetic, nonsmoking patients suffering from AMI, PD is highly prevalent and associated with elevated serum CRP, PC contents, sVCAM-1, TNF-α and resistin levels, associated with significant declines in antioxidant enzymes with insignificant change in serum adiponectin level.
