This cross-sectional study was conducted on 250 patients with T2DM, above 40 years of age, at King Abdulaziz University Hospital Diabetes Center in Riyadh, Saudi Arabia, between January and December 2006. Metabolic syndrome was defined, and compared according to 3 criteria, namely, National Cholesterol Education Program Adult Treatment Panel III, International Diabetes Federation, and World Health Organization. In the 250 patients studied, all 3 definitions demonstrated significant increase in the Apo B/Apo A-I ratio, in Saudi type 2 diabetics with the MetS. There was a strong positive correlation between the Apo B/Apo A-I ratio and triglycerides, low-density lipoprotein cholesterol, and total cholesterol (r=0.43-0.54, p<0.0001), and a weak, yet significant, correlation (r=0.14-0.21, p<0.05) with waist circumference, waist-h...

Since T2DM is usually preceded by obesity and chronic systemic inflammation, the objective of this study was to explore for any association between genetic variants of previously established 36 T2DM-associated SNPs and altered serum adipocytokine levels and metabolic syndrome phenotypes. Study consisted of 566 subjects (284 males and 282 females) of whom 147 were T2DM patients and 419 healthy controls. Study subjects were genotyped for 36 T2DM-linked single nucleotide polymorphisms (SNPs) using the KASPar SNP Genotyping System and grouped into different genotypes for each SNP. Various anthropometric and biochemical parameters were measured following standard procedures. The mean values of serum levels of individual adipocytokines and the presence/absence of metabolic syndrome phenotypes corr...

Irisin might play a role in &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;quot;browning&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;quot; of white adipocytes, thus increasing energy expenditure. The role of irisin in exercise and energy expenditure in subjects with diabetes mellitus type 2 (DMT2) remains largely unknown. We aimed to investigate the association between circulating irisin and habitual physical activity in subjects with and without DMT2. In this cross-sectional study, 164 Saudi adults: 81 non-DMT2 controls [age: (mean±SD) 51.6±10.9; BMI: 29.6±4.3kg/m(2) ] and 83 DMT2 subjects [age: 54.3±10.3yr; BMI: 29.4±4.7kg/m(2) ] were studied. Anthropometric and fasting serum biochemical data were collected. Circulating irisin was measured using an enzyme-linked immunosorbent assay (ELISA). Frequency intensity time (FIT) Index was used to assess the level of habitual physical activity. We observed significantly higher levels of irisin in DMT2 subjects than controls (p&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt;0.001). FIT index was positively associated (r=0.20, p=0.03) with circulating irisin in controls only. Additionally, irisin levels were significantly higher in tertile 3 (0.75±0.07μg/ml) compared to tertile 1 (0.49±0.06μg/ml) of the FIT index in healthy controls while no such relationship with physical activity was observed in DMT2 subjects. This cross-sectional study has shown a weak association of irisin with physical activity levels in healthy controls and none in DMT2 subjects, suggesting the possibility of discordant regulation in the condition of DMT2.

A total of 126 adult Saudi patients (55 men and 71 women, mean age 53.6 ± 10.7 years) with controlled T2DM were randomly recruited for the study. All subjects were given vitamin D3 tablets (2000 IU/day) for six months. Follow-up mean concentrations of serum 25-hydroxyvitamin D [25-(OH) vitamin D] significantly increased in both men (34.1 ± 12.4 to 57.8 ± 17.0 nmol/L) and women (35.7 ± 13.5 to 60.1 ± 18.5 nmol/L, p < 0.001), while levels of parathyroid hormone (PTH) decreased significantly in both men (1.6 ± 0.17 to 0.96 ± 0.10 pmol/L, p = 0.003) and women (1.6 ± 0.17 to 1.0 ± 0.14 pmol/L, p = 0.02). In addition, there was a significant increase in serum levels of selenium and magnesium in men and women (p-values < 0.001 and 0.04, respectively) after follow-up.

Selenium is an essential trace element because of role in major metabolic processes, immune function, thyroid hormone metabolism, male infertility, neoplasms and cardiovascular disease. We aimed to investigate for the first time in the Saudi population the association between vitamin D and selenium status with various dietary products consumption. A total of 259 children and 95 adults were included in this cross-sectional study. We estimated the consumption frequencies of various dietary food products using a qualitative food frequency questionnaire (FFQ) and also measured serum levels of 25-hydroxyvitamin D and selenium. Associations between variables of interest were assessed. Vitamin D deficiency and insufficiency were observed in 80% of the boys, 90% of the girls, 64% of men and 50% of women. Modest associations were found between mean serum 25 (OH) D concentration and consumpt...

The bone loss predominantly involves the trabecular bone and is brought about by an imbalance between the bone remodeling process which can be influenced by factors that could cause or contribute to osteoporosis. Pro-inflammatory cytokines (Il-1β, Il-6, IL-8 and TNF-α) have been implicated in the regulation of bone cells and play a critical role in bone remodeling. They act both directly and indirectly to increase bone resorption, and/or inhibit bone formation. The aim of the study is to determine whether pro-inflammatory cytokines correlate with bone turnover markers (BTM) in a cohort of Saudi post-menopausal women with or without osteoporosis and which BTMs will correlate with PTH and Vitamin D for use in osteoporosis diagnosis. The study is composed of 100 post-menopausal patients and 100 controls aged 50 years and above. Serum concentrations of pro-inflammatory and BTMs as we...

The study sought to examine inflammatory factors such as C-reactive protein, tumor necrosis factor-alpha and activated plasminogen activator inhibitor 1. A total number of 232 consenting Saudi adults, aged 18-60 years were randomly selected in this cross-sectional study. Independent Student t-test was done to compare means of normally distributed data. Spearman correlation between the variables was determined. The values of different fatty acids and adipokines were transformed logarithmically/square root to normalize data before correlations were determined and statistical analyses performed. Statistical significance was set at p<0.05. The results show a significant positive correlation of dietary intake of poly and monounsaturated fatty acids, but not saturated fatty acid...

The purpose of this study was to examine the association between 25-hydroxy-vitamin D (25-OH-VitD) levels and indices of insulin resistance (IR), including adipocytokines, in a Saudi population with or without DMT2. A total of 266 subjects (153 DMT2 and 113 healthy controls) aged 26-80 yr were randomly selected from the existing Biomarkers Screening in Riyadh Program (RIYADH Cohort). Subjects were assessed clinically, anthropometry was performed, morning blood chemistries, including fasting glucose (FG), triglycerides, total cholesterol, LDL cholesterol (LDL-C), and HDL cholesterol were obtained. Homeostasis model assessment of IR (HOMA-IR) was calculated, and serum 25-OH-VitD, leptin, adiponectin, resistin, insulin, high sensitivity CRP (hsCRP), and tumor necrosis factor α concentrations were measured using specific assays. In DMT2 subjects, n...

Three hundred and forty-one (177 non-diabetic, and 164 T2DM) Saudi adults were included in this cross-sectional study conducted at the Biomarkers Research Program (BRP) of King Saud University, Riyadh, Kingdom of Saudi Arabia from March to August 2009. Anthropometrics and fasting blood samples were obtained. Fasting glucose (FG) and lipid profiles were determined. Serum 25-hydroxy vitamin D (25[OH]D) and parathyroid hormone (PTH) were quantified using enzyme-linked immunosorbent assay. Severe hypovitaminosis D was defined as serum 25(OH)D with levels <12.5 nmol/l. Age was the most significant predictor of 25(OH)D in both groups, explaining 25% (p=0.0005) and 16% of variances (p=0.0005). Waist-hip ratio, systolic blood pressure and body mass index were significant predictors of 25(OH)D among non-diabetics after age adju...
