Consensus recommendations on fasting during Ramadan for patients with kidney disease: review of available evidence and a call for action (RaK Initiative).

Ramadan fasting (RF) involves abstaining from food and drink during daylight hours; it is obligatory for all healthy Muslims from the age of puberty. Although sick individuals are exempt from fasting, many will fast anyway. This article explores the impact of RF on individuals with kidney diseases through a comprehensive review of existing literature and consensus recommendations. This study was conducted by a multidisciplinary panel of experts.The recommendations aim to provide a structured approach to assess and manage fasting during Ramadan for patients with kidney diseases, empowering both healthcare providers and patients to make informed decisions while considering their unique circumstances.

Validation of the new IDF-DAR risk assessment tool for Ramadan fasting in patients with diabetes.

BACKGROUND: A new IDF-DAR (International Diabetes Federation - Diabetes and Ramadan Alliance) risk stratification tool was published in 2021 to better stratify the risk of Ramadan fasting in people with diabetes. METHODS: We performed a prospective, survey-based study before and after Ramadan 1442/2021 to explore the ability of the new IDF-DAR risk stratification tool to predict the probability of fasting and the risk of complications from fasting in people with diabetes. RESULTS: A pre-Ramadan assessment was completed for 659 patients who intended to fast in Ramadan; 647(98.2%) answered the post-Ramadan follow-up questionnaire. Mean age was 53.5 years and 47.9% were females. 603(91.5%) had type 2 diabetes while 56(8.5%) had type 1 diabetes. Using the IDF-DAR risk criteria at the pre-Ramadan assessment, 339(51.4%) were categorized as low-risk (score <3), 173(26.3%) as moderate-risk (score 3.5-6) and 147(22.3%) as high-risk (score >6). 94.3%, 81.1% and 76.9% patients fasted the full 30 days in the low, moderate and high risk groups respectively (p < 0.0001). Any hypoglycaemia was reported in the low, moderate and high risk groups by 6.3%, 21.9% and 35.0% respectively while severe hypoglycaemia was reported by 3(2.1%) patients in the high, 3(1.8%) in the moderate and none(0%) in the low risk groups. Hyperglycaemia (>250 mg/dL) was reported in the low, moderate and high risk groups by 2.7%, 13.0% and 23.8% respectively. CONCLUSION: The new IDF-DAR risk assessment tool appears to reliably predict both the ability to fast during Ramadan as well as the likelihood of getting hypoglycaemia or hyperglycaemia.

Clinical Characteristics and Outcomes of Diabetic Ketoacidosis in Patients With Type 2 Diabetes using SGLT2 Inhibitors.

Background: Sodium glucose cotransporter 2 inhibitors (SGLT2i) use is associated with an increased risk of diabetic ketoacidosis (DKA). Objective: This study evaluated and compared the DKA characteristics and outcomes of users and non-users of SGLT2i. Methods: We retrospectively studied patients with type 2 diabetes mellitus (T2DM) admitted with DKA to Tawam Hospital, Al Ain City, UAE between January 2017 and March 2021. Demographic data, clinical, and laboratory findings were extracted from the electronic medical records. Results: A total of 55 patients with T2DM (62% UAE nationals, 50% women) were admitted with DKA. The average age was 54.0 ± 18.9 years and average diabetes duration of 15.7 ± 15.1 years. Seventeen patients (31%) were using SGLT2i. Infection was the main precipitating factor for DKA in (8 out of 17) SGLT2i users. Compared to non-users, SGLT2i users had lower systolic blood pressure (119.9 vs 140 mmHg; P = .012) and serum glucose levels (16.2 vs 24.9 mmol/L; P < .001) and higher Na level (137.5 vs 132.6 mmol/L; P = .005). Additionally, 56.3% of SGLT2i users had euglycemic DKA compared to 2.6% of nonusers (P < .001). Acute kidney injury (AKI) occurred more in SGLT2i users compared to non-users (94.1% vs 67.6%, P = .043). Further analysis revealed that SGLT2i users were about five times more likely to have prolonged hospital length of stay (⩾14 days) when compared with non-users (adjusted OR: 4.84; P = .035). Overall, there was no difference between the two groups with regards to DKA complications and mortality. Conclusions: SGLT2i related DKA is associated with lower blood glucose levels, lower SBP, worse hypovolemia, increased risk of AKI, and longer hospital stay when compared to non SGLT2i related episodes. Since the benefits of SGLT2 inhibitors far outweigh potential risks, there is a need to raise healthcare professionals and patients' awareness about this potential association.

Fasting Ramadan in patients with T1DM - Saudi Arabia versus other countries during the COVID-19 pandemic.

BACKGROUND AND AIMS: To compare Saudi Arabia with other countries regarding patient attitudes towards fasting Ramadan and complications related to fasting during the COVID-19 pandemic. METHODS: Data collected from Saudi Arabia and 12 other mostly Muslim majority countries, via physician administered questionnaire within post Ramadan 2020. RESULTS: 1485 Type1 diabetes (T1DM) patients analyzed; 705 (47.5%) from Saudi Arabia vs. 780 (52.5%) from other countries. 1056 (71.1%) fasted Ramadan; 636 (90.2%) of Saudi patients vs. 420 (53.8%) of other countries. Experiencing Ramadan during the COVID-19 pandemic did not affect the Saudi T1DM patients' decision to fast while it significantly influenced their decision in other countries (1.4 vs 9.9%, P < 0.001). More Saudi patients needed to break the fast due to a diabetes related complication compared to other countries (67.4% vs. 46.8%, p=<0.001). The mean number of days fasted in Saudi and other countries was 24 ± 7 and 23 ± 8 days respectively. Hypoglycemic events were more common among Saudi patients during Ramadan compared to other countries 72% and 43.6% (p < 0.001) respectively. There was a significant difference in timing; the largest peak for Saudi Arabia patients was after dawn (35% vs 7%, p < 0.001), while it was pre-sunset for the other countries (23 vs 54%, p = 0.595). Day time-hyperglycemia was also more common among Saudi patients (48.6% vs. 39%, p < 0.001), however it was a less likely cause to break the fast (25.6% vs 38.3%, p < 0.001). CONCLUSION: Observing the fast of Ramadan is extremely common among Saudi T1DM patients compared to other Muslim countries and was not affected by the COVID-19 pandemic. However, it was associated with higher frequency of hypoglycemic and hyperglycemic episodes.

Continuous subcutaneous insulin infusion is associated with a better glycemic control than multiple daily insulin injections without difference in diabetic ketoacidosis and hypoglycemia admissions among Emiratis with Type 1 diabetes.

AIMS: To characterizes Emiratis patients with Type 1 diabetes (T1D) and compares outcomes between continuous subcutaneous insulin infusion (CSII) versus multiple daily insulin injections (MDI) users. The WHO-Five Well-Being Index (WHO-5) score was used to screen for depression. METHODS: In this cross-sectional study; sociodemographic, clinical characteristics and insulin replacement regimens were collected on patients with T1D between 2015-2018. RESULTS: 134 patients with mean age of 20.9±7.5 years were included. Females constitute 56.7% and 50.7% had diabetes duration of >10 years. Diabetic ketoacidosis (DKA) at presentation was reported in 46.3%. Average glycemic control over preceding 12months was satisfactory (less than 7.5%), suboptimal (7.5-9%), and poor (more than 9%) in 26.6%, 42.7% & 30.6% of the patients, respectively. Higher proportion of patients using CSII achieved satisfactory or suboptimal glycemic control compared to patients with MDI (P = 0.003). The latest median /IQR HbA1c was significantly lower (P = 0.041) in patients using CSII (8.2 /1.93%) compared to MDI (8.5/2.45%). There was no significant difference between two groups in DKA, severe hypoglycemia or total WHO-5 score. CONCLUSIONS: CSII usage was associated with better glycemic control than MDI, although no difference in DKA and severe hypoglycemia. The overall glycemic control among Emiratis subjects with T1D is unsatisfactory and needs more rigorous patient counseling and education.

Relationship between lipid profile, inflammatory and endothelial dysfunction biomarkers, and type 1 diabetes mellitus: a case-control study.

OBJECTIVE: Inflammation is a major factor in endothelial dysfunction (ED) which is the earliest predictor of cardiovascular disease and premature mortality in type 1 diabetes mellitus (T1DM) patients. This study aimed to describe the possible relationship between plasma lipids and inflammatory and ED biomarkers in young Emirati patients with and without T1DM. METHODS: This case-control study included 158 patients with T1DM and 157 healthy controls from the local population of the United Arab Emirates (UAE). Anthropometric data, clinical variables, lipid profiles, liver enzymes, HbA1c, inflammatory, and ED biomarkers were measured for all participants using sophisticated techniques and assays. RESULTS: The mean ages ± SD of patients with T1DM and healthy controls was 19.3 ± 6.4 years (59.5% females) and 9.2 ± 6.8 years (61.5% females), respectively. The mean duration of T1DM was 9.3 ± 5.7 years, with HbA1c of 8.9 ± 2.1%. BMI, WC, SBP, and DBP significantly differed between the two groups. The mean lipid profiles (HDL, TG, TC, ApoA, and ApoB), liver enzymes (GGT, ALT), inflammatory (IL-6, adiponectin, TNF-α, hs-CRP), and ED biomarker levels (ICAM-1, VCAM-1, selectin, and ET-1) were also significantly different between patients and controls. Based on Spearman's rank and logistic regression analysis, there was a significant association between elevated lipid profile, liver enzymes, inflammatory markers, and ED markers in T1DM patients compared to controls. Among the biomarkers studied, ApoA, ApoB, and TC were significantly increased in T1DM patients compared to controls. CONCLUSION: This study revealed a strong association between an elevated lipid profile and inflammatory and ED markers with T1DM, which could lead to cardiovascular events in the UAE population.

HLA-DRB1 and -DQB1 Alleles, Haplotypes and Genotypes in Emirati Patients with Type 1 Diabetes Underscores the Benefits of Evaluating Understudied Populations.

Background: HLA class II (DR and DQ) alleles and antigens have historically shown strong genetic predisposition to type 1 diabetes (T1D). This study evaluated the association of DRB1 and DQB1 alleles, genotypes, and haplotypes with T1D in United Arab Emirates. Materials and Methods: Study subjects comprised 149 patients with T1D, and 147 normoglycemic control subjects. Cases and controls were Emiratis and were HLA-DRB1 and -DQB1 genotyped using sequence-based typing. Statistical analysis was performed using Bridging Immunogenomic Data-Analysis Workflow Gaps R package. Results: In total, 15 DRB1 and 9 DQB1 alleles were identified in the study subjects, of which the association of DRB1*03:01, DRB1*04:02, DRB1*11:01, DRB1*16:02, and DQB1*02:01, DQB1*03:02, DQB1*03:01, and DQB1*06:01 with altered risk of T1D persisted after correcting for multiple comparisons. Two-locus haplotype analysis identified DRB1*03:01∼DQB1*02:01 [0.44 vs. 0.18, OR (95% CI) = 3.44 (2.33-5.1), Pc = 3.48 × 10-10]; DRB1*04:02∼DQB1*03:02 [0.077 vs. 0.014, OR = 6.06 (2.03-24.37), Pc = 2.3 × 10-3] and DRB1*04:05∼DQB1*03:02 [0.060 vs. 0.010, OR = 6.24 (1.79-33.34), Pc = 0.011] as positively associated, and DRB1*16:02∼DQB1*05:02 [0.024 vs. 0.075, OR = 0.3 (0.11-0.74), Pc = 0.041] as negatively associated with T1D, after applying Bonferroni correction. Furthermore, the highest T1D risk was observed for DR3/DR4 [0.104 vs. 0.006, OR = 25.03 (8.23-97.2), Pc = 2.6 × 10-10], followed by DR3/DR3 [0.094 vs. 0.010, OR = 8.72 (3.17-25.32), Pc = 3.18 × 10-8] diplotypes. Conclusion: While DRB1 and DQB1 alleles and haplotypes associated with T1D in Emiratis showed similarities to Caucasian and non-Caucasian populations, several alleles and haplotypes associated with T1D in European, African, and Asian populations, were not observed. This underscores the contribution of ethnic diversity and possible diverse associations between DRB1 and DQB1 and T1D across different populations.

Diabetes and Ramadan: Practical guidelines 2021.

Fasting during Ramadan is one of the five pillars of Islam and is obligatory for all healthy Muslims from the age of puberty. Though individuals with some illness and serious medical conditions, including some people with diabetes, can be exempted from fasting, many will fast anyway. It is of paramount importance that people with diabetes that fast are given the appropriate guidance and receive proper care. The International Diabetes Federation (IDF) and Diabetes and Ramadan (DaR) International Alliance have come together to provide a substantial update to the previous guidelines. This update includes key information on fasting during Ramadan with type 1 diabetes, the management of diabetes in people of elderly ages and pregnant women, the effects of Ramadan on one's mental wellbeing, changes to the risk of macrovascular and microvascular complications, and areas of future research. The IDF-DAR Diabetes and Ramadan Practical Guidelines 2021 seek to improve upon the awareness, knowledge and management of diabetes during Ramadan, and to provide real-world recommendations to health professionals and the people with diabetes who choose to fast.

Effects of Diabetes Prevention Education Program for Overweight and Obese Subjects with a Family History of Type 2 Diabetes Mellitus: A Pilot Study from the United Arab Emirates.

OBJECTIVES: The association of obesity and family history of type 2 diabetes mellitus (T2DM) provides an opportunity for risk stratification and prevention, as these two conditions are the most well-known risk factors for T2DM. We aimed to test the feasibility and effects of a diabetes mellitus prevention education program designed for overweight and obese Emirati people with at least one parent with T2DM. METHODS: We conducted a pilot study using a pre-post design without a control arm at the Diabetes Center at Tawam Hospital in Al Ain, UAE. Overweight and obese subjects with at least one parent with T2DM were invited to participate. Three study assessments were conducted at baseline, three months, and six months including a questionnaire, anthropometry, and laboratory assessments. Interventions included three individualized or family-engaged counseling sessions based on the DiAlert protocol. The study outcomes included awareness of risks and prevention opportunities to T2DM, behavior changes in nutrition and exercise, decreased waist-circumference, and clinical/metabolic/inflammatory markers. Pre-post changes were analyzed using repeated-measures analysis of variance. RESULTS: One hundred twenty-two overweight or obese individuals were approached. Forty-four individuals met the eligibility criteria, and 32 individuals (35.0±9.0 years; 75.0% female) completed the study. At six months, there were significant improvements in the glycated hemoglobin levels (p = 0.007), high-density lipoprotein (p < 0.049), serum creatinine (p < 0.025), estimated glomerular filtration rate (p = 0.009), and adiponectin levels (p < 0.024). Sixteen of 32 participants had ≥ 2 cm reduction in waist circumference. They demonstrated notable physical and laboratory improvements in moderate-vigorous activity, average activity counts per day, tumor necrosis factor-alpha, and interleukin-6 total cholesterol, triglyceride, and low-density lipoprotein. CONCLUSIONS: Offering family-oriented diabetes education to people at risk for T2DM is well received and has favorable effects on relevant risk factors. Better testing with large-scale randomized controlled studies is needed, and implementing similar educational programs for the Emirati population seems warranted.

Ultrasound-guided fine needle aspiration cytology and ultrasound examination of thyroid nodules in the UAE: A comparison.

BACKGROUND: Thyroid nodules are a common clinical finding and most are benign, however, 5-15% can be malignant. There is limited regional data describing the accuracy of ultrasound-guided fine needle aspiration (FNA) cytological examination compared to ultrasound examination of thyroid in patients who have undergone thyroid surgery. METHODS: A retrospective analysis of ultrasonographic (US) reports, FNA cytology reports and histopathology reports of 161 thyroid nodules presented at the endocrine center at Tawam hospital in Al Ain city, the United Arab Emirates during the period 2011-2019 was performed. US reports and images with FNA cytopathology reports and slides were reviewed by an independent radiologist and pathologist. RESULTS: In total, 40 nodules were reported as benign by US examination, while very low suspicious, low suspicious, intermediate suspicious and highly suspicious categories were reported in 21, 41, 14 and 45 nodules respectively. In addition, 68 nodules were reported as benign (Bethesda category II), while atypical follicular cells of unknown significance (Bethesda category III), follicular neoplasm (Bethesda category IV), suspicious for malignancy (Bethesda category V), and malignant (Bethesda category VI) categories were reported in 33, 9, 24 and 27 nodules respectively. The risk of malignancy for US benign nodules was 5%, while the risks of malignancy in very low suspicious, low suspicious, intermediate suspicious and highly suspicious nodules were 52%, 36%, 100% and 87%, respectively. The risk of malignancy for Bethesda category II was 3%, while the risks of malignancy in category III, IV, V and VI were 58%, 67%, 96% and 100%, respectively. CONCLUSION: Thyroid FNA cytological examination and ultrasonography are key tools in predicting malignancy in thyroid nodules. Thyroid nodules with the diagnosis of Bethesda category III & IV run a high risk of malignancy thus more vigilance is required.

Association of variants in PTPN22, CTLA-4, IL2-RA, and INS genes with type 1 diabetes in Emiratis.

Type 1 diabetes (T1D) is a chronic autoimmune disease with a complex interrelation of genetic and environmental factors. Genetic studies have reported HLA and non-HLA loci as significant contributors to T1D. However, the genetic basis of T1D among Emiratis is unexplored. This study aims to determine the contribution of four genes PTPN22, CTLA-4, IL2-RA, and INS to T1D risk among Emiratis. The association between variants in PTPN22 (rs2476601, rs1310182), CTLA-4 (rs11571316, rs231775, rs3087243, rs1427676, and rs231727), IL2-RA (rs7090530), and INS (rs7111341) with T1D was tested in 310 Emiratis (139 T1D patients and 171 controls). A significant association was found at rs1310182, and rs2476601 both in PTPN22, rs3087243, and rs231775 both in CTLA-4, and rs12251307 in IL2-RA. Moreover, a haplotype constituted from GG and AG genotypes at rs231727 and rs231775, respectively, in CTLA-4 was significantly associated with an increased T1D risk. The cumulative effects of risk alleles for all significantly associated SNPs showed 11.8 higher relative risk for T1D for those who carry 5-6 compared to 0-1 risk alleles. This study illustrated that PTPN22, CTLA-4, and IL2-RA gene variants could confer risk alleles for T1D among the Emirati population.

Association between type 2 diabetes mellitus & TCF7L2 gene variants in the Emirati population: Genetics of diabetes in the United Arab Emirates.

OBJECTIVE: Type 2 diabetes mellitus (T2DM) has a multifactorial etiology involving a complex interplay between genes and the environment. The prevalence of T2DM among the countries of the Gulf Corporation Council (GCC), including the United Arab Emirates (UAE), ranks among the top 15 in the world. A number of studies have shown an increase in T2DM risk for the "TT" genotype at the rs4506565 and rs12255372 Single Nucleotide Polymorphisms (SNP) of the TCF7L2 gene. However, the association between TCF7L2 and T2DM still needs to be investigated in the UAE population. Therefore, this study analyzed the potential associations with rs4506565 and rs12255372 in UAE subjects. METHODS: For this case-control study, T2DM patients (n = 890) and healthy subjects (n = 686) were genotyped using a Taqman Real-Time PCR assay. Statistical analysis was performed with the resulting data using the R (version 3.3.1) and STATA (version 13) software packages. RESULTS: The rs12255372 SNP was significantly associated with T2DM (OR = 1.16, 95% CI = 1.00-1.34; P = .042). However, no significant association was found for the rs4506565 SNP (P = .120). After gender stratification, a significant association was found for both SNPs in males (Prs4506565 = .009 and Prs12255372 = .021). Interestingly, we found the interaction between the SNP rs4506565 with gender alone (P = .032) and in conjunction with BMI and age (P = .036) confers associations with T2DM. CONCLUSIONS: These findings suggest that the genetic variants of the TCF7L2 gene are associated with an increased susceptibility to T2DM, especially in Emirati males. Our study also highlights the impact of biological and environmental risk factors including age, BMI, and gender on the genetic susceptibility to T2DM.

Use of SGLT2 inhibitors during Ramadan: An expert panel statement.

Fasting from dawn to sunset, during the holy month of Ramadan, constitutes one of the five main pillars in Islam and is observed by the majority of Muslims. Owing to important physiological changes, Ramadan fasting holds a crucial place in the context of diabetes management. Approximately one-fifth of the world's Muslim population resides in the Middle East and Africa (MEA) region. To discuss the challenges and management of diabetes during Ramadan fasting in the MEA region, a panel of 12 experts in the field of diabetes from across the MEA region attended two expert committee meetings held in Dubai. The key point of discussion was the safety and efficacy of the use of sodium-glucose co-transporter 2 inhibitors (SGLT2i) during Ramadan, based on outcomes of the recent clinical trials with SGLT2i. This is the first consensus recommendation on the management of diabetes with SGLT2i across the MEA region during Ramadan. The document summarizes expert views and opinions on the current management of diabetes with SGLT2i during Ramadan and aims to enhance the current knowledge and understanding on the issue of diabetes management during Ramadan. This will aid the physicians of the MEA region with appropriate decision-making for their patients during Ramadan.

Clinical Presentation, Treatment, and Outcome of Acromegaly in the United Arab Emirates.

OBJECTIVES: We sought to ascertain the clinical characteristics and control rate of acromegaly in the UAE. METHODS: We conducted a multicenter retrospective analysis of all patients presenting with acromegaly to six endocrine centers in the UAE between November 2010 and December 2018. Demographic, clinical, biochemical, and radiologic data were collected. Patients were considered controlled if normal insulin-like growth factor-1 (IGF-1) level and growth hormone < 1 mcg/L were achieved at their last visit. RESULTS: A total of 75 patients were included in the study (60.0% males, 33.3% native UAE nationals). The mean age at diagnosis was 37.2 (range: 12-69) years. Common clinical features at diagnosis were headache (82.4%), coarse facial features (82.4%), acral enlargement (79.7%), and sweating (31.3%). Diabetes mellitus/prediabetes and hypertension were present in 45.2% and 35.5% of patients, respectively. About 82.2% had pituitary macroadenoma on pituitary magnetic resonance imaging. At presentation, 27.0% and 3.2% of the patients had secondary hypogonadism and diabetes insipidus, respectively. Overall, 76.7% of the patients underwent surgery, 20.8% received radiotherapy, and 50.7% received medical therapy. At their last clinic visit, only 43.7% of all patients achieved disease control. CONCLUSIONS: Our study shows a high prevalence of pituitary macroadenoma in our acromegalic population, suggesting a delayed diagnosis. Also, a significant proportion of patients remained uncontrolled. Efforts to increase physician's awareness of acromegaly and to improve disease control are underway.

Genetics of type 2 diabetes and coronary artery disease and their associations with twelve cardiometabolic traits in the United Arab Emirates population.

BACKGROUND: The United Arab Emirates (UAE) population has a high rate of type 2 diabetes mellitus (T2DM) and other metabolic risk factors for coronary artery disease (CAD). Previous studies have indicated strong genetic associations between T2DM and CAD. The objective of this study was to replicate previously reported significant genetic associations for T2DM and CAD which were in a genome-wide significance level in a cohort from the Arab population of the UAE, and to investigate the associations of these loci with twelve cardiometabolic traits that may influence the development of T2DM and CAD. METHODS: A total of nine hundreds and fourteen Emiratis were recruited to this study to investigate associations of 101 loci for T2DM (422 patients and 455 controls), and 53 loci for CAD (160 patients and 245 controls), using logistic regression models which incorporating possible confounding factors. Results are presented using odds ratios with their corresponding 95% confidence intervals and p-values. Linear regression models, which included possible covariates were applied to determine any associations between the T2DM and CAD reported loci with the twelve cardiometabolic traits and results were presented as effect sizes (beta), standard errors, and p-values. Furthermore, the overall risks for all the loci found to be associated with T2DM and CAD were determined using the cumulative effects of the risk alleles. For those found to be associated with the twelve cardiometabolic traits, risks were determined using calculations of their polygenic risk scores. RESULTS: The mean age of the T2DM group was 61.5 ± 11.3 and of the CAD group was 66.2 ± 9.3 years. The prevalence of most of the cardiovascular disease risk factors in this cohort were high: mean body mass index (BMI) = 29.4, T2DM (51.9%), hypertension (60.9%), dyslipidemia (68.8%), and smoking (47.9%). All individuals who were tested for CAD (n = 405) also had a diagnosis of T2DM. The highest association variant for T2DM was in SNP rs1977833 in HHEX (p = 0.0016, OR = 0.56 for allele A), which is a multi-ethnic locus for T2DM. The strongest association with CAD was detected with SNP rs264 in LPL, which encodes lipoprotein lipase (p = 0.009, OR = 1.96 for allele A). For the cardiometabolic traits analyses, most notable associations were those of FTO with BMI and waist circumference; ABO with height; KCNK16 with diastolic blood pressure; PROX1-AS1, GCKR, and MIR129-LEP with fasting blood glucose; random blood glucose with ZEB2 and THADA; HbA1c levels with TLE1 and FAM99B loci; HDL-cholesterol levels with BRAF; and triglyceride levels with ZEB2. Furthermore, accumulation of risk alleles and polygenic scores of the associated loci was clearly associated with increased risks for all tested diseases and traits in this cohort. CONCLUSIONS: The present study highlighted many known genetic loci, which are linked to T2DM and CAD and their associations with major cardiometabolic traits in Arab descendants. We confirmed that some loci are associated with T2DM, CAD, and metabolic traits independently of the ethnic background, with a novel association also detected between height and ABO.

BRAF and KRAS mutations in papillary thyroid carcinoma in the United Arab Emirates.

BACKGROUND: Papillary thyroid carcinoma (PTC) is the most common malignant thyroid neoplasm comprising 80-90% of all thyroid malignancies. Molecular changes in thyroid follicular cells are likely associated with the development of PTC. Mutations in serine/threonine-protein kinase (BRAF) and Rat sarcoma viral oncogene homolog (RAS) are commonly seen in PTC. METHODS: In total, 90 cases of PTC are randomly selected from archive paraffin blocks and 10µm sections were cut and processed for DNA extraction. BRAF V600E mutation and 8 types of KRAS mutations were investigated using Real Time PCR. RESULTS: BRAF V600E mutation was identified in 46% of PTC while KRAS mutations were seen in 11% of PTC. There was significant correlation between BRAF V600E mutation and PTC larger than 5cm in diameter, positive surgical margin and lymph node metastasis. BRAF V600E mutation was significantly higher in patients with less than 55-year of age than those more than 55-year of age. BRAF V600E mutation was significantly higher in patients with family history of thyroid cancer than those without. There was no significant difference in BRAFV600E mutation between males and females, PTC classic and follicular variants, unifocal and multifocal PTC. There was a significant higher percentage of BRAF V600E mutation in classic PTC than papillary microcarcinoma variant. There was no significant age, gender, histologic type, tumor size, lymph node metastasis, tumor focality, and surgical margin status differences between KRAS mutated and non-mutated PTC. CONCLUSION: BRAF V600E and KRAS mutation are seen in a significant number of PTC in the UAE. BRAF mutation is significantly correlated with large tumor size, positive surgical margins and lymph node metastasis suggesting an association between BRAF V600E mutation and tumor growth and spread.

The value of Continuous Glucose Monitoring and Self-Monitoring of Blood Glucose in patients with Gestational Diabetes Mellitus during Ramadan fasting.

INTRODUCTION: In order to achieve the recommended glycemic control, women with Gestational Diabetes Mellitus (GDM) are instructed to self-monitor blood glucose (SMBG) regularly. The purpose of this study was to evaluate glucose readings provided by Continuous Glucose Monitoring (CGM) and SMBG in GDM patients during Ramadan fasting. METHODS: This is a prospective observational study that recruited GDM patients treated with diet ± metformin were enrolled. They agreed to wear the iPro®2 ProfessionalCGM device and to do SMBG by glucose reading meters, during fasting and after meals. We evaluated the rates of hypoglycemia and hyperglycemia in each approach. The frequency and timing of SMBG was investigated. RESULTS: Twenty-five patients were recruited. A total of 36,628 readings by CGM device and 408 readings using glucose meters and were captured. Average glucose level was 103 ±â€¯8 mg/dl (5.7 ±â€¯0.4 mmol/l) and 113 ±â€¯14 mg/d (6.28 ±â€¯0.8 mmol/L) on CGM and glucose meters respectively. The rate of hyperglycemia was 5.65% and 14.2% and hypoglycemia was 4.35% and 1.5% using CGM and glucose meters respectively. While all hypoglycemic episodes occurred between 16:00-19:00 in both approaches, only 38 readings (9%) of SMBG readings were done in that time frame. CONCLUSION: Although the frequency of SMBG using glucose meters for women with GDM and fasting Ramadan was acceptable, the timing was not. CGM detected more hypoglycemia and less hyperglycemia than SMBG. Relying on Intermittent SMBG in the management of GDM patients during Ramadan fasting might be misleading.

Diabetic hypoglycaemia during Ramadan fasting: A trans-national observational real-world study.

OBJECTIVES: To describe the risk of hypoglycaemia during Ramadan and determine its risk factors, and the impact of hypoglycaemia on patients' behaviour. METHODS: A cross-sectional multi-country observational study, with data captured within 6 weeks after Ramadan 2015. Patients' and disease characteristics and its management, the risk of hypoglycaemia and patients' response to hypoglycaemia were recorded. RESULTS: A cohort of 1759 patients; majority with type 2 diabetes mellitus from North Africa, Arabian Gulf, Saudi Arabia, and the Indian subcontinent. Hypoglycaemia was reported by 290 patients (16.8%); particularly affecting type 1 diabetes patients and in insulin-treated patients in general. Age was significantly younger in the hypoglycaemia group (P < 0.001). The commonest responses were reducing the dose or frequency of medications (42%), attending primary care providers (24.5%) or increasing monitoring (20.7%). Fasting was interrupted by 67% only of those who experienced hypoglycaemia and recourse to emergency services was pursued by less than a quarter of patients with hypoglycaemia. The country-wise analysis of the rates of hypoglycaemia was greatest in Egypt (51.3%) and lowest in Pakistan (3.5%). CONCLUSIONS: Hypoglycaemia is a significant complication of fasting during Ramadan. It may be predicted by type of diabetes, and use of insulin. Patients' responses are varied and call for more formal pre-Ramadan education.

Challenges in the management of Type 2 Diabetes among native women in the United Arab Emirates.

AIM: To investigate Type 2 Diabetes mellitus (T2DM) management in native female patients in the United Arab Emirates (UAE). METHODS: Ninety women from the outpatient diabetes clinic at Tawam Hospital, UAE, were interviewed face-to-face about how they manage their disease, using a structured questionnaire. Clinical values of the patients were extracted from medical records. RESULTS: The mean age of the women was 57.5 (SD: 12.7) years and half of them were illiterates. Two-third of the participants had hypertension and/or high cholesterol. A majority reported to have received information about lifestyle modification but admitted low physical activity and unhealthy diet. Mean weight and BMI were 80.0 (SD: 17.2) kg and 33.5 (SD: 6.3) kg/m2, respectively. Although the majority were taught how to measure blood glucose, 46% considered self-measurement difficult. Oral antihyperglycemic drugs were used by 96% of participants, and 31% were also taking injections. Forty-nine percent had HbA1c values below 7% and the average was 7.7% (range: 4.9-14.1). Two-third had systolic blood pressure (SBP) and low-density lipoprotein (LDL) values within the target range. CONCLUSION: Despite major challenges in T2DM management among native female patients in UAE, this study shows that one in two patients had an overall glycemic control that was acceptable.
