Changes in body composition in the obese state lead to a dysregulation of secretion of adipocyte-secreted hormones known as adipokines. The current study aimed to assess the relative physiological correlation of adipocytokines with immunity in urban Saudi patients. The serum adipocytokine (leptin, adiponectin, resistin, visfatin and apelin), metabolic parameters (insulin, fasting glucose, HbA1c % (Glycated Hemoglobin) immunological indices (IgG, IgA, IgM and IgE) and complement factors (C3, C4) in different metabolic disorders states such as obesity and T2DM (Type 2 Diabetes Mellitus) were determined. A total 100 adult male subjects were enrolled including 30 healthy that served as a control, 25 Glucophage treated T2DM, 22 overweight (Body Mass Index (BMI) ≥ 25 - 29.99) and 23 obese (BMI ≥ 30) patients. The current results showed that serum adipocytokines status has altered in obesity and treated T2DM compared to healthy individuals. In addition to HbA1c %, serum visfatin was also the prominent biomarker adipokine in treated T2DM while leptin was the highest in obese (BMI ≥ 30). These metabolic disorders did not affect serum levels of the assessed immunity indices. Current knowledge suggests that adipokines provide potential therapeutic targets against type 2 diabetes and vascular disease. This study provides a strong association between adipocytokine and IR (Insulin Resistance). With the increasing epidemic of obesity and T2DM in Saudi Arabia, these adipocytokine markers that integrate metabolic and inflammatory signals may play important roles in the treatment and prevention of obesity and diabetes as well as planning of therapeutic strategies and the early detection of diabetes.展开更多

Methods An age, gender and ethnicity matched case-control study was conducted to genotype the representative single neucleotide polymorphisms （SNPs） loci including rs1061170 and rs1410996 in CFH, rs641153 and rs4151667 in BF and rs11200638 in HTRA1 gene in 144 exudative AMD patients and 126 normal controls using PCR-RFLP and direct resequencing. The demographic characteristics and behavioral risk factors were also recorded. Allelic and genotypic associations for individual SNP and joint associations with two loci were performed. The gene-gene and gene-environment interactions were analyzed using multivariate non-conditional Logistic regression analysis. Results The C risk allele frequencies for CFH Y402H （rs1061170） in cases and controls were 12.5% and 5.4% respectively, which were much lower than those in Caucasians （P 〈0.001）. Compared with TT homozygous genotype, the CT heterozygous genotype was positively associated with AMD with odds ratio （OR） of 3.23 （1.36-5.07）. However, the population attributable risk （PAR） of C allele was only 3.3% （1.4%-4.3%）. rs1410996 was also associated with AMD independent of Y402H. The ORs of exudative AMD for individuals carrying one copy risk allele and two copy risk alleles were 2.57 （1.21-5.45） and 4.76 （2.15-10.55） respectively, with correspondent PARs of 28.3% （2.0%-40.5%） and 38.2% （21.8%-45.4%）. rs11200636 in HTRA1 was another susceptible locus for AMD and the risk homozygotes were significantly susceptible for exudutive AMD （OR=3.98, 1.88-8.43） with PAR of 38.9% （24.3%-45.8%）展开更多
