RESUMEN

Genetic variations of microRNA encoding genes influence various sorts of diseases by modifying the expression or activity of microRNAs. MicroRNA 146a is an epigenetic regulator of immune response through controlling the type I interferon (IFN) and nuclear factor kappa B (NF-κB) pathways. Genetic variations of microRNA 146a impact the susceptibility to systemic lupus erythematosus (SLE) and its clinical presentations. This study aimed to investigate the polymorphisms of microRNA-146a gene (rs2431697 and rs57095329) in patients with SLE and its association with disease activity. Sixty-five patients with SLE and 40 apparently healthy controls were enrolled in this study. Patients were subjected to history taking, clinical examination, and disease activity evaluation by SLEDAI score. The microRNA-146a variants were determined by allele discrimination real-time PCR method in all participants. We found a statistically significant association between rs2431697 T allele and SLE (P-value < 0.05), but there was no significant association between rs57095329 and SLE. The T/T genotype of microRNA-146a rs2431697 was associated with lupus nephritis, higher disease activity, and autoantibodies production. The microRNA-146a rs2431697 T allele could be a potential risk factor that contributes to SLE susceptibility, development of lupus nephritis, and disease activity.

RESUMEN

BACKGROUND: Gestational diabetes mellitus (GDM) has serious consequences such as increased risks of preeclampsia, macrosomia and cesarean delivery. Even though the mechanistic basis of GDM has not been completely understood, several risk factors have been identified and one of these is vitamin D. However, the link between vitamin D deficiency and development of GDM is yet to be proven with certainty. METHODS: This study aimed to investigate the link between the incidence of GDM and serum vitamin D level in pregnant women of Saudi Arabia. 515 Saudi women (ages 18-46) in their 24-28th week of pregnancy, visiting various hospitals of Riyadh, participated in this study. Serum vitamin D and various biochemical and anthropometric parameters were determined in the first trimester and the recruits were screened for GDM by OGTT according to IADPSG criteria in their 2nd trimester. The association between vitamin D deficiency and development of GDM was calculated based on odds ratio of the incidence of GDM among vitamin D deficient and normal women. RESULTS: In this study cohort of 515 pregnant women, in the first trimester vitamin D deficiency (< 50 nmol/l) was detected in 425 (82.5%). On their 2nd visit (2nd trimester), 116 (27.7%) were diagnosed with GDM out of 419 with OGTT, according to IADPSG criteria. GDM risk was significantly higher among vitamin D deficient than non-deficient women (Odds Ratio: 2.87; Confidence Interval: 1.32-6.25; P = 0.008) even after adjusting for season, sun exposure and vitamin D intake (OR: 2.9; CI: 1.07-7.89). Of the various anthropometric and biochemical parameters, the GDM women differed significantly from non-GDM women with respect to serum levels of triglycerides (in mmol/l) (1.3 ± 0.6; 1.5 ± 0.6, p = 0.018) and fasting glucose (in mmol/l) [4.7 (4.3-5.2); 5.1 (4.6-5.6), p < 0.01]. Also, fasting glucose level in the 2nd trimester correlated inversely to serum vitamin D level determined during the 1st trimester (r = - 0.121; p = 0.014). CONCLUSIONS: Results of our study reveal a significantly higher risk of development of GDM among pregnant women having deficient vitamin D status.

RESUMEN

BACKGROUND: Vitamin D deficiency is a common nutritional issue and dietary supplementation in the general population, including pregnant women, is generally advised. Appropriately high levels of vitamin D are expected to play a role in containing the glycemic and atherogenic profiles observed in pregnancy. However, the relation between vitamin D status and the lipid metabolic profile in Saudi women, who are known to suffer from chronic vitamin D deficiency and high incidence of obesity and type II DM, during the course of pregnancy is not known. METHODS: In this study, we analyzed the relation between serum vitamin D level and various serum metabolic markers among Saudi women (n = 515) in their first trimester of pregnancy (11.2 ± 3.4 weeks). Coefficients of Pearson correlation and Spearman rank correlation were calculated for Gaussian and non-Gaussian variables, respectively. Serum vitamin D status was defined as (in nmol/L): deficient (<25), insufficient (25-50); sufficient (50-75) and desirable (>75). RESULTS: Results indicated that vitamin D status was sufficient in only 3.5% of the study participants and insufficient and deficient in 26.2% and 68.0% of participants, respectively. Serum vitamin D values in the overall study population correlated positively with serum levels of total cholesterol (R = 0.172; p < 0.01), triglycerides (R = 0.184; p < 0.01) and corrected calcium (R = 0.141; p < 0.05). In the subgroup of vitamin D deficient subjects (n = 350), log serum vitamin D values correlated with serum triglycerides (R = 0.23; p = 0.002) and cholesterol (R = 0.26; p = 0.001). CONCLUSIONS: The positive correlations between serum vitamin D and the atherogenic factors such as total cholesterol and triglycerides indicate a pro-atherogenic metabolic status in vitamin D deficient expectant mothers. This may represent an adaptation to the high metabolic demands of pregnancy.

RESUMEN

BACKGROUND: Low bone mineral density (BMD) is a public health issue in Saudi Arabia. This study measured the prevalence and factors associated with low BMD in Saudi women in Riyadh, Saudi Arabia. METHODS: A cross sectional study using two stage cluster sampling technique was conducted in Riyadh, 2009. Thirty clusters, each comprising of 300 houses were randomly chosen and from each cluster 38-40 households were selected to identify 1150 women of >40 years. Women were invited to primary health care center for filling of self-administered questionnaire (n = 1069) comprising of sociodemographic, health, diet and physical activity variables. 1008 women underwent screening for low BMD using the quantitative ultrasound technique. 535 (53%) women with positive screening test were referred to King Khalid Hospital for Dual X-ray Energy absorptiometry (DXA). RESULTS: 362 women underwent DXA and 212 (39.6%) were screened low BMD either at lumbar spine or femur neck. Mean age of women was 55.26(±8.84) years. Multivariate logistic analysis found; being aged 61 to 70 years (OR 2.75, 95% CI: 1.32-1.48), no literacy (OR 2.97, 95% CI:1.44 - 6.12) or primary education (OR 4.12, 95% CI:2.05-8.29), history of fractures (OR 2.20, 95% CI:1.03- 4.69) and not drinking laban(diluted yogurt) (OR 2.81, 95% CI:1.47- 5.37) significantly associated with low BMD. CONCLUSIONS: Women with low level of education, who do not drink laban and had history of fractures were at high risk of low BMD.

RESUMEN

This is a review of the changing pattern of chronic diseases among women in the Kingdom of Saudi Arabia (KSA). Data from national surveys conducted in KSA, whose results were published between 1996 and 2011 were used. The results showed that over a period of ten years the prevalence of obesity increased in Saudi women from 23.6% to 44.0% and in men from 14.2% to 26.2%; self-reported physical inactivity worsened in both women (from 84.7% to 98.1%) and men (from 43.3% to 93.9%); prevalence of smoking in women increased (from 0.9% to 7.6%), while it declined in men (from 21.0% to 18.7%). The prevalence of metabolic syndrome was significantly greater in women than men (42.0% versus 37.2%; p <0.01). In conclusion, Saudi women are potentially at a greater risk than a decade ago to develop cardiovascular diseases and diabetes mellitus, with a notable increase in obesity compared to men.

RESUMEN

OBJECTIVE: To provide clinicians with an update on the diagnosis of celiac disease (CD) and to make recommendations on the indications to screen for CD in patients presenting with low bone mineral density (BMD) or fragility fractures. QUALITY OF EVIDENCE: A multidisciplinary task force developed clinically relevant questions related to the diagnosis of CD as the basis for a literature search of the MEDLINE, EMBASE, and CENTRAL databases (January 2000 to January 2009) using the key words celiac disease, osteoporosis, osteopenia, low bone mass, and fracture. The existing literature consists of level I and II studies. MAIN MESSAGE: The estimated prevalence of asymptomatic CD is 2% to 3% in individuals with low BMD. Routine screening for CD is not justified in patients with low BMD. However, targeted screening for CD is recommended for patients who have T-scores of -1.0 or less at the spine or hip, or a history of fragility fractures in association with any CD-related symptoms or conditions; family history of CD; or low urinary calcium levels, vitamin D insufficiency, and raised parathyroid hormone levels despite adequate intake of calcium and vitamin D. Celiac disease testing should be performed while the subject is consuming a gluten-containing diet; initial screening should be performed with human recombinant immunoglobulin (Ig) A tissue transglutaminase or other IgA tissue transglutaminase assays, in association with IgA endomysial antibody immunofluorescence. Duodenal biopsy is necessary to confirm the diagnosis of CD. Human leukocyte antigen typing might assist in confirming or ruling out the diagnosis of CD in cases where serology and histology are discordant. Definitive diagnosis is based on clinical, serologic, and histologic features, combined with a positive response to a gluten-free diet. CONCLUSION: Current evidence does not support routine screening for CD in all patients with low BMD. A targeted case-finding approach is appropriate for patients who are at higher risk of CD.

RESUMEN

While moderate to severe vitamin D deficiency is prevalent in Saudi Arabia, skeletal effects associated with this deficiency are not common in this population. In this interventional study we measured the effects of improving vitamin D status on bone biochemical markers in overweight and obese adult Saudis. A total of 47 volunteers (21 males, 26 females) out of the initial 95 subjects were given verbal advice to expose themselves to sunlight for 5-30 min twice weekly and were encouraged to increase their intake of vitamin D-rich foods. Serum 25(OH)D, osteocalcin, and type 1 collagen cross-linked C-telopeptide (CTx), were measured at baseline and after one year. A significant decrease in the prevalence of vitamin D deficiency was observed (44% to 27%) after one year follow-up (p = 0.025). Also, a parallel significant increase in osteocalcin and a decrease in CTX and osteoprotegerin were observed. The results suggest that a modest increase in vitamin D levels among overweight and obese subjects through the promotion of lifestyle changes for one year have marginal effects in bone turnover markers as well as obesity itself.

RESUMEN

Thousands of videos are posted on websites and social media every day, including Twitter, Facebook, WhatsApp, Instagram, and YouTube. Newspapers, law enforcement publications, criminal investigations, surveillance systems, Banking, the museum, the military, imaging in medicine, insurance claims, and consumer photography are just a few examples of places where important visual data may be obtained. Thus, the emergence of powerful processing tools that can be easily made available online poses a huge threat to the authenticity of videos. Therefore, it's vital to distinguish between true and fake data. Digital video forgery detection techniques are used to validate and check the realness of digital video content. Deep learning algorithms lately sparked a lot of interest in the field of digital forensics, such as Recurrent Neural Networks (RNN), Deep Convolutional Neural Networks (DCNN), and Adaptive Neural Networks (ANN). In this paper, we give a soft taxonomy as well as a thorough overview of recent research on multimedia falsification detection systems. First, the basic knowledge needed to comprehend video forgery is provided. Then, a summary of active and passive video manipulation detection approaches is provided. Anti-forensics, compression video methods, datasets required for video forensics, and challenges of video detection approaches are also addressed. Following that, we presented an overview of deepfake, and the datasets required for detection were also provided. Also, helpful software packages and forensics tools for video detection are covered. In addition, this paper provides an overview of video analysis tools that are used in video forensic applications. Finally, we highlight research difficulties as well as interesting research avenues. In short, this survey provides detailed information and a broader investigation to extract data and detect fraud video contents under one umbrella.

RESUMEN

The Saudi Osteoporosis Society (SOS) has updated its guidelines for the diagnosis and management of osteoporosis in Saudi Arabia (SA), with emphasis on postmenopausal women. This document is relevant to all healthcare professionals in SA involved in the care of patients with osteoporosis and osteoporosis-related fractures. INTRODUCTION: The SOS launched the first national osteoporosis guidelines in 2015 and spearheaded the Gulf Cooperation Council Countries (GCC) osteoporosis consensus report in 2020 which was under the auspices of the European Society for Clinical and Economic Aspects of Osteoporosis (ESCEO). This paper highlights a major update of the guidelines in the SA setting. METHODS: This guideline is an adaptation of the current guidelines derived from ESCEO, the American Association of Clinical Endocrinologists (AACE), and the GCC osteoporosis consensus report and studies on osteoporosis done in SA. Where accessible, the timeliest systematic review, meta-analysis, and randomized controlled trials were used as evidence. RESULTS: The present update includes new recommendations for the assessment of osteoporosis taking into consideration the Saudi model of FRAX for fracture probabilities, appropriate doses for the maintenance of vitamin D status and calcium, the use of representative blood analytes for therapy monitoring, the use of romosozumab and sequential therapy in the pharmacological management strategies, and the establishment of fracture liaison services to prevent secondary fractures. CONCLUSION: This updated guideline is for all healthcare professionals involved in osteoporosis and post-fracture care and management in SA and harmonized the most up-to-date changes in the field based on evidence-based medicine for use in the local setting.

RESUMEN

OBJECTIVE: To review the evaluation and management of skeletal health in patients with celiac disease (CD), and to make recommendations on screening, diagnosis, treatment and follow-up of low bone mineral density (BMD) in CD patients. METHODS: A multidisciplinary team developed clinically relevant questions for review. An electronic search of the literature was conducted using the MEDLINE and EMBASE databases from 1996 to 2010. All original studies, reviews and guidelines, both pediatric and adult, were included. A document summarizing the results of the review and proposed recommendations was prepared and underwent multiple revisions until consensus was reached. RESULTS: At diagnosis, approximately one-third of adult CD patients have osteoporosis, one-third have osteopenia and one-third have normal BMD. Children with CD have low bone mass at diagnosis. Adult and pediatric CD patients are at increased risk of fractures. DISCUSSION: For adults, serum calcium, albumin, 25(OH) vitamin D3, parathyroid hormone and 24 h urine calcium testing should be performed at diagnosis; patients with 'classic' CD and those at risk for osteoporosis should undergo a dual x-ray absorptiometry scan. An abnormal baseline dual x-ray absorptiometry scan should be repeated one to two years after initiation of a gluten-free diet (GFD). For children, BMD should be assessed one year after diagnosis if GFD adherence is not strict. A GFD is the most important treatment for bone loss. Supplemental antiresorptives may be justified in those who remain at high fracture risk (eg, postmenopausal women, older men) after implementation of a GFD. CONCLUSION: Current evidence does not support the screening of all CD patients for low BMD at diagnosis. Follow-up BMD assessment should be performed one to two years after initiation of a GFD.

RESUMEN

Biochemical bone turnover markers (BTMs) provide important information on the diagnosis, therapy and monitoring of metabolic bone diseases. They are evident before measurable changes in bone mineral density (BMD) take place. A total of 35 adult Saudi patients (23 males; 12 females) with type 2 diabetes and diagnosed to be vitamin D deficient were recruited in this prospective study. Here we investigated the effects of gender, season, and vitamin D status on bone biochemical markers of bone remodeling. Anthropometry and blood samples were collected at different intervals. Metabolic parameters and bone biomarkers were measured routinely and by ELISA. Both males and females had a significant increase in their vitamin D status over time, but no significant changes in the bone biomarkers were observed in females. In males there was a significant increase in circulating levels of corrected calcium and OPN (p = 0.004 and 0.01 respectively) and a significant decrease in crosslaps (p = 0.005). In all subjects there was a modest but significant positive relationship between vitamin D status and OC (R = 0.34; p = 0.04). In conclusion, our study demonstrates that changes in bone remodeling markers are affected by season, gender, and possibly vitamin D status. This gender difference may well reflect the physiologic pathway responsible for the higher peak bone mass achieved in males compared to females.

RESUMEN

Purpose: Impact of ramadan fasting on healthy and women with diabetes is already known. However, there is a scarcity of data on impact of fasting on pregnant women with diabetes. Moreover, religious and medical recommendations advise pregnant women against fasting as it is unsafe. Despite being exempted, many pregnant Muslim women with diabetes still choose to fast during ramadan. This study investigated different glycemic marker as an indicator for diabetes control in fasting pregnant women. Patients and Methods: This is a prospective observational study. A total of 89 pregnant diabetes women were recruited. Blood glucose was self-monitored in all the pregnant women using glucose monitoring device at home. We measure the fructosamine, HbA1c levels before, during and after ramadan. Results: Pregnant women with type 1 diabetes were 14 (25%), type 2 diabetes were 21 (37.5%), and gestational diabetes were 21 (37.5%). The mean fructosamine level decreased during and after ramadan in gestation diabetes pregnant women compared to type 2 diabetes and type 1 diabetes pregnant women subjects (p = 0.009). Conclusion: The present study indicates that pregnant women with diabetes were able to fast during ramadan and there fructosamine level reduced during fasting. Utilization of fructosamine for short-term monitoring of glycemic control in addition to home glucose monitoring in pregnant women with diabetes will provide a good index of glycemic control. Recommendation: Religious and medical recommendations advise pregnant women against fasting as it is unsafe, and they are under high risk. However, if they insist to do fast, they must do under strict medical supervision and fructosamine can be used as a glycemic control marker.

RESUMEN

The aim of this study was to examine the feasibility and effectiveness of telemedicine care provided to osteoporotic patients in Saudi Arabia. Our results show that this service was effective and feasible, and patients had a good rate of satisfaction with it. PURPOSE: To investigate the efficacy and feasibility of telemedicine care in osteoporotic patients during the COVID-19 lockdown period in Saudi Arabia compared to in-person patients, as well as their satisfaction with this service. METHODS: This observational retrospective study was conducted between March 2021 and September 2021 in King Saud University Medical City, Saudi Arabia. A survey was used to compare patients attending telemedicine clinics with in-person patients in terms of access and adherence to medications, occurrence of new fractures, and overall satisfaction with this service. RESULTS: 195 patients attended the telemedicine clinic, while 63 attended the in-person clinic. Exercise frequency was similar in both groups, although exercise intensity was greater in the in-person group. 25(OH)D levels were stable in both groups. The availability and delay of supply of osteoporosis medications were not statistically different between both groups while adherence to treatment did not differ significantly between the two groups. The majority of patients in the telemedicine group were satisfied. CONCLUSIONS: Telemedicine care was feasible and effective in managing osteoporotic patients during the COVID-19 epidemic. Such service could be considered in the future for managing disabled patients and those living in remote areas.

RESUMEN

Metabolic syndrome (MetS) is a serious health condition that is becoming extremely threatening in Saudi Arabia. The link between vitamin D receptor (VDR) gene polymorphisms and maternal MetS has been observed in several ethnic groups, but is yet to be clarified in the Arabian population. This study aims to investigate the relationship between the FokI VDR genotype and the risk of MetS and its components in pregnant Saudi women. A cross-sectional study was conducted using 368 pregnant Saudi women on first trimester screened for MetS (44 with MetS and 324 without MetS). Measurements included anthropometrics, glycemic and lipid profile and 25(OH)D. TaqMan genotyping assay was used to determine Fokl VDR genotype of participants. Vitamin D deficiency (25(OH)D <50nmol/l) was seen in 85% of the participants. An estimated 12% of participants had MetS. In the MetS group, the FokI VDR genotyping frequencies for FF, Ff, and ff genotypes were 50%, 36.4% and 13.6%, respectively. In controls, the frequencies were 62.7%, 31.4% and 5.9%, respectively. No significant association between the individual MetS components and FokI VDR genotypes were observed. Nevertheless, carriers of the ff allele had a significant risk for full maternal MetS [Odds Ratio 4.2 (95% Confidence Interval 1.4-12.2; adjusted p=0.009). The study suggests that the ff FokI VDR genotype is a genetic marker of maternal MetS in pregnant Arabian women. Prospective studies that include neonatal outcomes may confirm present findings.

RESUMEN

BACKGROUND: Saudi Arabia has a high burden of diabetes mellitus and vitamin D deficiency. The objective of this study was to explore the association between glycosylated hemoglobin and 25-hydroxyvitamin D in patients with type 2 diabetes mellitus (T2DM) in Riyadh, Saudi Arabia. METHODS: An interview based cross-sectional study was conducted on 606 patients with type 2 diabetes, aged 30-75 years, visiting primary health care centers. Blood samples were collected for measuring HbA1c, 25(OH)D and bone and lipid markers. Multivariable linear regression analysis was conducted to explore the association between HbA1c and 25(OH)D. RESULTS: The mean (±SD) levels for HbA1c and 25(OH) D were 7.69 (±1.77) and 44.28 (±23.06), respectively. Around 55% of patients had uncontrolled HbA1c (>7.0), whereas vitamin D deficiency (<50 nmol/L) was found in 52.3% (=317). Multiple linear regression analysis found that a unit increase in vitamin D levels and parathyroid hormone levels was associated with -0.17 (-0.02, -0.01, p < 0.001) and -0.20 (-2.66, -1.18, p < 0.001) unit decrease in levels of HbA1c, respectively. Similarly, increasing age was associated with -0.15 (-0.01, -0.04, p = 0.002) unit decrease in HbA1c levels, whereas unit increases in serum alkaline phosphatase, calcium and diabetes duration were associated with 0.22 (0.01, 0.02, p < 0.001), 0.14 (1.03, 3.88, p = 0.001) and 0.26 (0.42, 0.78, p < 0.001) unit increase in HbA1c levels, respectively. CONCLUSION: HbA1c levels are associated with 25-hydroxyvitamin D levels. For better control of HbA1c levels, it is important to maintain 25-hydroxyvitamin D level and bone markers within normal range.

RESUMEN

Osteoporosis and its complications are a major health concern in Saudi Arabia, and the prevalence of osteoporosis is on the rise. The aim of this study was to estimate the direct healthcare cost for patients with osteoporosis. A retrospective study was carried out among adult patients with osteoporosis in a teaching hospital in Saudi Arabia. A bottom-up approach was conducted to estimate the healthcare resources used and the total direct medical cost for the treatment of osteoporosis and related fractures. The study included 511 osteoporosis patients, 93% of whom were female. The average (SD) age was 68.5 years (10.2). The total mean direct medical costs for patients without fractures were USD 975.77 per person per year (PPPY), and for those with osteoporotic fractures, the total direct costs were USD 9716.26 PPPY, of which 56% of the costs were attributable to surgery procedures. Prior to fractures, the main cost components were medication, representing 61%, and physician visits, representing 18%. The findings of this study indicated the economic impact of osteoporosis and related fractures. With the aging population in Saudi Arabia, the burden of disease could increase significantly, which highlights the need for effective prevention strategies to minimize the economic burden of osteoporosis.

RESUMEN

Introduction: This study aimed to investigate the association between components of metabolic syndrome (MetS) at first trimester and development of Gestational diabetes mellitus (GDM) in 498 Saudi pregnant women. Materials and Methods: Biochemical and anthropometric parameters were determined at the first trimester and MetS components were defined. Participants were screened for GDM at follow up according to International Association of Diabetes and Pregnancy Study Group (IADPSG) criteria. The main outcome measures were development of GDM and GDM risk vs. MetS components at first trimester. Results: One hundred twenty three (24.7%) were diagnosed with GDM according to IADPSG criteria. GDM risk was significantly higher for participants with hypertriglyceridemia at 1st trimester even after adjusting for age, BMI and parity (OR: 1.82; CI: 1.1-3.7, p = 0.04). Furthermore, the odds of hyperglycemia at 1st trimester was significantly higher in GDM than in non-GDM participants even after adjustments (OR: 2.13, 95% CI: 1.1 to 4.3, p = 0.038). The receiver operating characteristic (ROC) for predicting GDM revealed an area under the curve (AUC) of 0.69 (95% CI: 0.64 to 0.74, p < 0.001) and 0.71 (95% CI: 0.65 to 0.77, p < 0.001) for first-trimester hyperglycemia and hypertriglyceridemia respectively. Conclusions: The incidence of GDM in Saudi pregnant women was strongly associated with hyperglycemia and hypertriglyceridemia at first trimester. These findings are of clinical importance, as an assessment of MetS in early pregnancy can identify women at higher risk of developing GDM.

RESUMEN

OBJECTIVE: A summary of recommendations is given within the Gulf Cooperation Council (GCC) setting on the assessment and management of vitamin D deficiency in the region. METHODS: An assembly of 11 regional experts gathered to formulate an all-inclusive approach to vitamin D deficiency within GCC. RESULTS AND CONCLUSION: Several gaps were identified before regional guidelines could be developed. These include adequacy and standardization of vitamin D testing, frequency of repeated testing and reference ranges, distinguishing prevention from the treatment of vitamin D deficiency, quality assurance of vitamin D products sold within GCC including contents and origins of products, and cut-points for vitamin D levels in local populations. A platform is created that can be further developed for overall regional implementation.

RESUMEN

OBJECTIVE: To determine clinical manifestation and mode of treatment of Graves' disease at King Khalid University Hospital Riyadh, Saudi Arabia. METHODS: A retrospective study of all cases of Graves' disease diagnosed at the hospital in the period between January 1995 and December 2004, who received a minimum of two years treatment were included in the study. RESULTS: A total of 194 patients were seen with female: male ratio of 2.9:1 and mean age of 32 +/- 0.9 years. Sixty nine percent of the patients had positive thyroid antibodies. Palpitations, tremors, weight loss and nervousness were the most common presenting manifestations. Forty nine percent of patients were treated with radioiodine, 38% with antithyroid drugs, and 13% underwent subtotal thyroidectomy. CONCLUSION: Clinical manifestations of Graves' disease in our patients distinctly differed from those reported in the West and Pacific Islanders with notable rarity of pretibial myxoedema and hyperpigmentation respectively. We also noted higher male to female ratio and an increasing utility of radioactive iodine therapy while use of antithyroid drugs and surgery are declining.
