Objectives:To study the effect of Vitamin D 3 supplementation on metabolic control in an obese type 2 diabetes Emirati population.Methods:This randomized double-blind clinical trial was conducted with 87 vitamin D-deficient obese, type 2 diabetic participants. The vitamin D-group (n=45) and the placebo group (n=42) were matched for gender, age, HbA1c and 25-hydroxy vitamin D (25(OH) D) at the baseline. The study was divided into two phases of 3 months each; in phase 1, the vitamin D-group received 6000 IU vitamin D 3 /day followed by 3000 IU vitamin D 3 /day in phase 2, whereas the placebo group (n=42) received matching placebo.Results:After supplementation, serum 25(OH) D peaked in the vitamin D-group in phase 1 (77.2±30.1 nmol/l, P=0.003) followed by a decrease in the phase 2 (61.4±18.8 nmol/l, P=0.006), although this was higher compared with baseline. In the placebo group, no difference was observed in the serum 25(OH) D levels throughout the intervention. Relative to baseline serum, parathyroid hormone decreased 24% (P=0.003) in the vitamin D-group in phase 2, but remained unchanged in the placebo group. No significant changes were observed in blood pressure, fasting blood glucose, HbA1c, C-peptide, creatinine, phosphorous, alkaline phosphatase, lipids, C-reactive protein or thyroid stimulating hormone concentrations compared with baseline in either group.Conclusions:Six months of vitamin D 3 supplementation to vitamin D-deficient obese type 2 diabetes patients in the UAE normalized the vitamin D status and reduced the incidence of eucalcemic parathyroid hormone elevation but showed no effect on the metabolic control. © 2015 Macmillan Publishers Limited.

Background: The prevalence of diabetes has risen rapidly in the Middle East, particularly in the Gulf Region. However, some prevalence estimates have not fully accounted for large migrant worker populations and have focused on minority indigenous populations. The objectives of the UAE National Diabetes and Lifestyle Study are to: (i) define the prevalence of, and risk factors for, T2DM; (ii) describe the distribution and determinants of T2DM risk factors; (iii) study health knowledge, attitudes, and (iv) identify gene-environment interactions; and (v) develop baseline data for evaluation of future intervention programs. Methods: Given the high burden of diabetes in the region and the absence of accurate data on non-UAE nationals in the UAE, a representative sample of the non-UAE nationals was essential. We used an innovative methodology in which non-UAE nationals were sampled when attending the mandatory biannual health check that is required for visa renewal. Such an approach could also be used in other countries in the region. Results: Complete data were available for 2719 eligible non-UAE nationals (25.9% Arabs, 70.7% Asian non-Arabs, 1.1% African non-Arabs, and 2.3% Westerners). Most were men<65 years of age. The response rate was 68%, and the non-response was greater among women than men; 26.9% earned less than UAE Dirham (AED) 24000 (US$6500) and the most common areas of employment were as managers or professionals, in service and sales, and unskilled occupations. Most (37.4%) had completed high school and 4.1% had a postgraduate degree. Conclusion: This novel methodology could provide insights for epidemiological studies in the UAE and other Gulf States, particularly for expatriates. © 2015 Ruijin Hospital, Shanghai Jiaotong University School of Medicine and Wiley Publishing Asia Pty Ltd.

The co-existence of vitamin D deficiency with obesity and type 2 diabetes is highly prevalent in the United Arab Emirates. We do not have studies evaluating the vitamin D dose response and sufficiency, and if sufficient substitution dose during a longer period could decrease obesity or change fat distribution in obese type 2 diabetic vitamin D deficient Emiratis.A randomized double-blind clinical trial was conducted for 6 months followed by another 6 months of un-blinded follow up with 87 obese, type 2 diabetic participants. Serum 25-hydroxy vitamin D (S-25(OH)D), anthropometric data, and life-style factors such as diet and sunlight exposure were measured. The study was executed in 3 phases in two arms vitamin D arm (n = 45) and placebo arm (n = 42); in Phase 1 the vitamin D arm received 6000 IU vitamin D3/day (3 months) followed by Phase 2 with 3000 IU vitamin D3/day. During follow up (phase 3) both the arms were un-blinded and supplemented with 2200 IU vitamin D3/day for another 6 months.At the baseline a significant (p < 0.01) positive association between body fat mass and body weight (r = 0.97) muscle mass (r = 0.47), water mass (r = 0.54), waist circumference (r = 0.82) and serum PTH (r = 0.28) was observed. On supplementation no significant changes in anthropometric dimensions was observed. S-25(OH) D peaked in phase 1 (77.2 30.1 vs 28.5 9.2, p = 0.003) followed by a decrease in phase 2 (62.3 20.8, p = 0.006) paralleled by a decrease in parathyroid hormone in phase 2 (5.9 2.4 vs 4.5 1.8, p < 0.01) compared to baseline in vitamin D group.This study shows no significant influence of vitamin D supplementation on weight, fat mass or waist circumference in type 2 diabetic obese vitamin D deficient participants of Arab ethnicity after one year. Despite a relatively high daily dose of vitamin D3 we did not achieve target levels of S-25(OH)D above 75 nmol/L in this population. However, supplementation was safe, improved s- 25 (OH)D also reducing the incidence of eucalcemic parathyroid hormone elevation.ClinicalTrials.gov Identifier: NCT02101151.

Aim. To report vitamin D status and its impact on metabolic parameters in people in the United Arab Emirates with obesity and type 2 diabetes (T2D).Methodology. This cross-sectional study included 309 individuals with obesity and T2D who were randomly selected based on study criteria. Serum concentrations of 25-hydroxy vitamin D (s-25(OH)D), calcium, phosphorus, parathyroid hormone, alkaline phosphatase, glycemic profile, and cardiometabolic parameters were assessed in fasting blood samples, and anthropometric measurements were recorded.Results. Vitamin D deficiency (s-25(OH)D < 50 nmol/L) was observed in 83.2% of the participants, with a mean s-25(OH)D of 33.8 ± 20.3 nmol/L. Serum 25(OH)D correlated negatively (P<0.01) with body mass index, fat mass, waist circumference, parathyroid hormone, alkaline phosphatase, triglycerides, LDL-cholesterol, and apolipoprotein B and positively (P<0.01) with age and calcium concentration. Waist circumference was the main predictor of s-25(OH)D status. There was no significant association between serum 25(OH)D and glycemic profile.Conclusion. There is an overwhelming prevalence of vitamin D deficiency in our sample of the Emirati population with obesity and T2D. Association of s-25(OH)D with body mass index, waist circumference, fat mass, markers of calcium homeostasis and cardiometabolic parameters suggests a role of vitamin D in the development of cardiometabolic disease-related process. © 2014 Amena Sadiya et al.

Diabetic gastroparesis (DGP), or slow emptying of the stomach, is a well-established complication of diabetes mellitus and is typically considered to occur in individuals with long-standing type 1 and type 2 diabetes mellitus. Clinical consequences of DGP include induction of gastrointestinal (GI) symptoms (early satiety, abdominal distension, reflux, stomach spasm, postprandial nausea, vomiting), alteration in drug absorption, and destabilization of glycemic control (due to mismatched postprandial glycemic and insulin peaks). Effective nutritional management not only helps in alleviating the symptoms, but also in facilitating better glycemic control. Although there have been no evidence-based guidelines pertaining to the nutrition care process of the DGP, the current dietary recommendations are based on expert opinions or observational studies. The dietary management of gastroparesis needs to be tailored according to the severity of malnutrition and kind of upper GI symptom by changing the volume, consistency, frequency, fiber, fat, and carbohydrates in the meal. Small frequent meals, using more liquid calories, reducing high fat or high fiber, consuming bezoar forming foods, and adjusting meal carbohydrates based on medications or insulin helps in improving the upper GI symptoms and glycemic control. Enteral nutrition can be an option for patients who fail to stabilize their weight loss, or for those who cannot gain weight with oral feedings, while total parenteral nutrition is rarely necessary for the patient with gastroparesis. © 2012 Sadiya, publisher and licensee Dove Medical Press Ltd.

Background: Lifestyle Intervention for Weight Loss (LIFE-8) is developed as a structured, group-based weight management program for Emiratis with obesity and type 2 diabetes. It is a 3-month program followed by a 1-year follow-up. The results from the first 2 years are presented here to indicate the possibility of its further adaptation and implementation in this region. Methodology: We recruited 45 participants with obesity and/or type 2 diabetes based on inclusion/exclusion criteria. The LIFE-8 program was executed by incorporating dietary modification, physical activity, and behavioral therapy, aiming to achieve up to 5% weight loss. The outcomes included body weight, fat mass, waist circumference, blood pressure, fasting blood glucose (FBG), hemoglobin A1c (HbA1c), and nutritional knowledge at 3 months and 12 months. Results: We observed a reduction of 5.0% in body weight (4.8±2.8 kg; 95% CI 3.7-5.8), fat mass (-7.8%, P<0.01), and waist circumference (Δ=4±4 cm, P<0.01) in the completed participants (n=28). An improvement (P<0.05) in HbA1c (7.1%±1.0% vs 6.6%±0.7%) and FBG (8.2±2.0 mmol/L vs 6.8±0.8 mmol/L) was observed in participants with obesity and type 2 diabetes after the program. Increase in nutritional knowledge (<0.01) and overall evaluation of the program (9/10) was favorable. On 1-year follow-up, we found that the participants could sustain weight loss (-4.0%), while obese, type 2 diabetic participants sustained HbA1c (6.6%±0.7% vs 6.4%±0.7%) and further improved (P<0.05) the level of FBG (6.8±0.8 mmol/L vs 6.7±0.4 mmol/L). Conclusion: LIFE-8 could be an effective, affordable, acceptable, and adaptable lifestyle intervention program for the prevention and management of diabetes in Emiratis. It was successful not only in delivering a modest weight loss but also in improving glycemic control in diabetic participants. © 2016 Sadiya et al.

Bariatric surgery has become an attractive treatment for severe obesity over the last decade, due to its impacts on weight loss and remission of type 2 diabetes and metabolic syndrome. In the United Arab Emirates, a country where the rate of obesity is dramatically increasing bariatric surgery has gained popularity in recent years; however, published data on its outcomes in the Emirati population are lacking.We retrospectively reviewed the medical records of 95 patients who underwent bariatric surgery (ie, laparoscopic Roux-en-Y gastric bypass [RYGB] or laparoscopic sleeve gastrectomy) at the Rashid Center for Diabetes and Research in Ajman, United Arab Emirates. Weight outcomes and metabolic marker data were abstracted at baseline and at 3, 6, and 12 months postoperatively.Laparoscopic RYGB was the main procedure performed by our bariatric unit. All variables demonstrated postoperative improvement. An average excess weight loss of 68% was observed at 12 months. Fat mass was the body component that decreased the most, with an average reduction of 46%. Additionally, lipid profiles were significantly different (P<0.01) at 12 months, with triglyceride levels improving by 27% and low-density lipoprotein levels improving by 21%. Similarly, glycated hemoglobin (HbA1c) levels decreased significantly (P<0.001) in patients with type 2 diabetes, with an average reduction of 73%.Our results show that a substantial short-term reduction in weight and significant improvements in metabolic markers followed bariatric surgery in severely obese Emirati patients. Our results are consistent with the outcomes of other internationally published studies. Additional studies are warranted to determine whether the favorable impacts of bariatric surgery can be sustained over the long term.

Our study sought to evaluate the association between periodontitis and body mass index (BMI) among patients with type 2 diabetes mellitus..In this cross-sectional case control study analysis of 186 diabetic patients, 112 patients had a body mass index 30kg/m(2) and 74 control patients had BMI <30kg/m(2). All participants underwent oral examinations including a full mouth recording of clinical attachment level (CAL). Information regarding HbA1c levels and high-sensitivity C-reactive protein (hs-CRP) were also gathered..Over half (61%) of patients had a BMI 30. Of these 52% had CAL less than 2mm. Multivariate logistic regression analysis showed that there was no association between BMI and CAL. In addition, hs-CRP levels were significantly and positively associated with CAL (OR:1.06, 95% CI: 1.01, 1.12; p=0.007)..Among patients with type 2 diabetes mellitus, there was no association between periodontitis and BMI. More studies are needed to further explore this relationship taking into consideration additional lifestyle factors.
