Glycemic control, complications, and associated autoimmune diseases in children and adolescents with type 1 diabetes in Jeddah, Saudi Arabia

Prevalence of celiac disease in Moroccan children with type 1 diabetes mellitus: A 16-year cross-sectional study

BACKGROUND

There is limited data available regarding the prevalence of celiac disease (CD) among children with type 1 diabetes mellitus (T1DM) in Arab countries and the Middle East. This cross-sectional study has been designed to explore the prevalence of CD specifically within the population of Moroccan children and adolescents diagnosed with type 1 diabetes mellitus (T1DM).

PATIENTS AND METHODS

This is a cross-sectional study of patients who underwent regular follow-up for T1DM at the Pediatric Endocrinology Unit, Abderrahim Harouchi Children's University Hospital in Casablanca, over a 16-year period from 2004 to 2020. Patients were screened for CD by measuring anti-tissue transglutaminase IgA, and those with positive antibodies underwent endoscopy assessment.

RESULTS AND DISCUSSION

All 550 patients regularly followed up with TIDM were screened for CD. Fifty-five (33 girls/22 boys) of the screened patients had histologically documented CD, yielding a prevalence of 10%. Nineteen (41.9%) patients had developed CD within the initial four years of diagnosis with T1DM. Therefore, among the six confirmed CD patients, the average age at the onset of T1DM was 3.7 years. For twenty-four (57.5%) of the patients, exhibited no apparent clinical indications of CD, and their condition was only identified through systematic screening.

CONCLUSION

This study showed a high prevalence rate of CD associated with type 1 diabetes T1DM, particularly among young children. The results of this paper indicate one of the highest prevalence rates reported in the existing literature for the coexistence of CD and T1DM. These findings may suggest the necessity of a systematic screening of CD in T1DM patients.

Prevalence and Risk Factors of Diabetic Nephropathy Among Saudi Type-1 Diabetic Patients in Taif City, Saudi Arabia

Purpose

We investigated the prevalence and associated risk factors of DNP in T1DM patients in Taif city, Saudi Arabia, where the renal diseases are prevalent. The incidence of diabetic nephropathy (DNP) is increasing in Saudi Arabia, and the country is also ranked 4th in terms of the number of diagnosed type-1 diabetes (T1DM) patients.

Patients and Methods

The retrospective cohort study was conducted with type-1 diabetes patients registered at King Abdulaziz Specialist Hospital in Taif, Saudi Arabia. A total of 198 patients (aged > 18 years), had T1DM for more than 5 years with documented albuminuria; albumin-creatinine ratio (ACR) ≥30 mg/g creatinine in two of three urine samples or estimated glomerular filtration rate (eGFR) <60 mL/min/1.73 m2, were included in the study. Patients' demographic and laboratory data were collected from medical records. A regression analysis model was used to identify risk factors for DNP. Statistical significance was set at P < 0.05.

Results

The overall prevalence of DNP was 23.7% in our study group, with 8% having low eGFR alone, 20.71% having positive ACR and 6.22% having both positive ACR and low eGFR. A statistically significant correlation between DNP and risk factors was found for uncontrolled and longer duration of T1DM, elevated ACR, and hypertension (P < 0.05). No statistical significance was found for age, sex, or body mass index (BMI).

Conclusion

The prevalence of DNP in T1DM patients in Taif city was higher (23.7%) than the pooled average prevalence in Saudi Arabia (20.59%). Patients' education regarding glycemic and blood pressure control could reduce the burden.

Hypoglycemia unawareness among insulin-treated diabetic patients in Madinah, Saudi Arabia: prevalence and risk factors

Background

Hypoglycemia unawareness (HU) is associated with significant risks. Screening for impaired awareness of hypoglycemia in patients with diabetes is important to minimize those risks. There are limited data on the prevalence of HU in patients with diabetes in Saudi Arabia (KSA). In the current study, we investigated the frequency of HU and its risk factors among insulin treated diabetic patients in Madinah, KSA.

Methods

A cross-sectional study was conducted in a diabetes center and four primary healthcare centers at Madinha, KSA. Patients ≥14 years old with type 1 or type 2 diabetes treated with insulin for more than a year were included. HU was assessed by Clarke's and modified Pedersen-Bjergaard's scores. The risk factors for HU were determined.

Results

Of the 413 included patients, 60.3% were women, and 60.8% were on insulin alone. One-third of the participants had T1DM, while 68.5% had T2DM, with median ages of 25 and 56 years, diabetes durations of 10 and 15 years, and durations of insulin use of 10 and 5 years, respectively. The prevalence of HU was 25.2% by Clarke's survey. The risk factors for HU were poor knowledge of the patient's latest HbA1c, type of insulin, and dose of insulin. Poor medical follow-up, previous stroke, and ischemic heart disease were the other risk factors for HU. When the modified Pedersen-Bjergaard method was used, the prevalence of HU was 48.9%.

Conclusion

Despite the advances in diabetes management, HU continues to be prevalent among diabetic patients on insulin, and poor diabetes knowledge is a major risk factor. Diabetes education on self-management is of utmost importance to reduce hypoglycemia and HU.

Associated autoimmune thyroid diseases in children and adolescents with type one diabetes in Jordan

OBJECTIVES

To investigate the prevalence of thyroid autoimmunity and related thyroid disorders among children and adolescents with type 1 diabetes in Jordan.

METHODS

In a retrospective study, thyroid stimulating hormone and thyroid hormone (Free T4) levels were measured in 684 children with type 1 diabetes who presented to Jordan University Hospital between January 2012 and February 2021. Anti-thyroid peroxidase (TPOAb) and anti-thyroglobulin (TGAb) antibodies were measured in 526 and 438 subjects with type 1 diabetes, respectively.

RESULTS

681 children were included in the study (52.4 % females, average current age 14.3 years, average age at diagnosis 8.0 years, and average diabetes duration 6.2 years). Of the whole group, 18 children (2.6 %) were diagnosed with subclinical hypothyroidism and 31 children (4.4 %) had overt hypothyroidism. Of those who were tested for TPOAb and TGAb, 22.6 and 23.1 % were positive respectively. Predictors for developing hypothyroidism were female sex and positive antibodies to glutamic acid decarboxylase.

CONCLUSIONS

Screening for associated thyroid autoimmunity in children and adolescents with type one diabetes from Jordan is advised with a special focus on females and those with positive antibodies to glutamic acid decarboxylase.

Poor glycemic control and its associated factors among children with type 1 diabetes mellitus in Harar, eastern Ethiopia: A cross-sectional study

BACKGROUND

Poor glycemic control increases the risk of acute metabolic derangements and long-term consequences, which are the main causes of morbidity and mortality. Maintaining adequate glycemic control is challenging for children with diabetes, particularly in resource-limited settings. There is a paucity of data on the magnitude of poor glycemic control and its predisposing factors in Ethiopian particularly in this study setting. Hence, we aimed to assess the magnitude of poor glycemic control and its associated factors among children and adolescents with type 1 diabetic mellitus in Jugol and Hiwot Fana Compressive Specialized University Hospitals in Harar, eastern Ethiopia.

METHODS

A facility-based cross-sectional study was conducted among 231 children and adolescents with type 1 diabetes mellitus in Jugol and Hiwot Fana Compressive Specialized University Hospitals. Participants were included consecutively in the follow-up clinic from November 15, 2022 to January 15, 2023. Data were collected through an interviewer-administered structured questionnaire and a review of medical records. A binary logistic regression model with an adjusted odds ratio (aOR) and a 95% confidence interval (CI) was used to identify the factors associated with poor glycemic control. Statistical significance was set at p < 0.05.

RESULT

A total of 231 children and adolescents with type 1 diabetes mellitus were included. The magnitude of poor glycemic control was 166 (71.9%) with 95% CI 66.0-77.7%). In multivariable analysis, the age of the child (aOR = 0.19, 95% CI: 0.05-0.83), education of the caregiver (aOR = 4.13;95% CI: 1.82-9.46), meal frequency less than three (aOR = 3.28; 95% CI: 1.25-8.62), and consumption of forbidden foods (aOR = 3.17; 95% CI: 1.21-8.29) were factors significantly associated with poor glycemic control.

CONCLUSION

Two-thirds of participants had poor glycemic control. There was a statistically significant association between the age of the child, education of the caregiver, meal frequency, and forbidden foods with poor glycemic control. To improve glycemic control, diabetes education on meal use and selection should be conducted during follow-up along with parent education.

Autoimmune diseases and their prevalence in Saudi Arabian patients with type 1 diabetes mellitus

OBJECTIVES

To evaluate the prevalence of autoimmune disorders among young and adult populations diagnosed with type 1 diabetes mellitus (T1DM) in Al-Madinah Al-Munawarah, Saudi Arabia, and assess the potential impact of these conditions on other comorbidities.

METHODS

A retrospective, descriptive study examined autoimmune disorders in T1DM youth and adults. A total of 2258 verified T1DMs were tested. Analyzed hospital and laboratory data. Autoimmune T1DM was investigated clinically and laboratory.

RESULTS

A total of 2258 T1DM adults, adolescents, and children were investigated; 500 (22.2%) were under 12, 540 (23.9%) were 13-17, and 1218 (53.9%) were 18 plus. Autoimmune with T1DM was 67.4%. Gender and age affect prevalence. 25.7% of adult females had autoimmune thyroiditis. Children and adolescents have greater rates of celiac disease than adults of both genders. Adrenal insufficiency was more frequent in adults. Adult males had 28.5% polyglandular autoimmune diseases, and women had 19.7%. Type 1 DM and other autoimmune illnesses increase the risk of nephropathy, CVD, and hypoglycemia. Bloodstream biomarkers linked to these disorders corroborate this.

CONCLUSION

Autoimmune diseases in Saudi patients with T1DM exhibited specificity with respect to gender and age. Al-Madinah Al-Munawwarah have a heightened prevalence of autoimmune diseases among young individuals diagnosed with T1DM, such as celiac disease and autoimmune thyroiditis. Conversely, older individuals in the region have been observed to exhibit a greater incidence of adrenal failure and polyglandular autoimmune disorders. Autoimmune diseases that result in nephropathy, CVD, and hypoglycemia are highly prevalent based on biomarker levels.

Epidemiological profile and diabetes control of Type 1 Diabetes Mellitus patients in Karbala Governorate, Iraq

Background: Type1 Diabetes Mellitus is a common chronic diseases among children, and associated with morbidity, mortality, and enormous healthcare expenditures. Objectives; to estimate the prevalence, incidence, and describe the epidemiological characteristics of Type 1 Diabetes Mellitus among children in Karbala governorate. Methods: A cross-sectional study was conducted among all children who attended the main DM center in Karbala Teaching Hospital for Children, Public Clinics, and Primary Health Care centers. Data was collected by structured questionnaire and biochemical and anthropometric measurements. The statistical analysis data entry was conducted using Statistical Package for Social Sciences. Results: Total number of Type 1 Diabetes Mellitus patients aged 0-15 years in Karbala in 2015 was 199; making 44.66/100 5. Fifty-four patients were newly diagnosed patients making an incidence of 12.11/100 5. There was nearly equal distribution among both sexes. Most of the cases were from urban areas and most of the patients had a Family history of Type 2 Diabetes Mellitus. Diabetic ketoacidosis was reported in 16.8% of the patients. Only 31.6% of patients had HbA1c < 7%. Half of the patients had a history of admission to the hospital for diabetes. Logistic regression analysis revealed that the only independent variables significantly correlated with poor glycemic control were lack of Self-Monitoring Blood Glucose, irregular visits to the Diabetic Center, and positive family history of diabetes. Conclusion: Only one-third of T1DM children in Karbala city had controlled blood sugar. Lack of regular blood glucose monitoring and irregular contact with health care providers were the main determinants of uncontrolled blood sugar.

Gender differences in knowledge, attitudes, and practices with respect to type 1 diabetes among Saudi public-school teachers

BACKGROUND

Children with type 1 diabetes mellitus (T1DM) need carefully monitoring even during school hours to avoid emergencies. Hence, it is crucial for teachers to have appropriate knowledge and positive attitudes toward diabetes to effectively manage the disease and its complications. This study aimed to compare the knowledge, attitudes, and practices with respect to T1DM among Saudi male and female public-school teachers living in Jeddah and to identify the associated factors.

METHODS

A cross-sectional study was conducted among primary, intermediate, and secondary public-school teachers working in Jeddah, Saudi Arabia between October 2021 and March 2022. Data were collected through an online survey. The survey included information on the socio-demographics of school teachers, the presence of chronic diseases, teachers' health behaviours, and knowledge, attitude, and practice with respect to T1DM.

RESULTS

This study included 378 school teachers. The majority of school teachers from both genders were married, held a bachelor's degree, and aged 45-54 years. Male school teachers were married (P = 0.02), held postgraduate certificates (P < 0.001), smoked cigarette and shisha (P < 0.001), and were physically active (P < 0.001) compared to female school teachers. Regarding teachers' knowledge of T1DM, it was found that female teachers were significantly more knowledgeable of T1DM children's and its symptoms than male teachers (P = 0.03; P = 0.01, respectively). However, male teachers were more willing to accommodate T1DM students in their classes and attend programs to support T1DM students as compared to female teachers (P = 0.004; P = 0.004, respectively). Moreover, the study showed poor practice scores for T1DM. In addition, the knowledge, attitudes, and practice scores toward T1DM were significantly associated with advanced age (P = 0.002), and extended years of teaching experience (P ≤ 0.002). Also, diabetic teachers had the highest knowledge (P = 0.03) and attitude (P = 0.02) scores compared to non-diabetic teachers. Male teachers who were married (P = 0.002), shisha smokers (P = 0.01), and had never practiced activity (P = 0.03) had better attitudes and practices toward T1DM. Similarly, female teachers who held bachelor's certificates had better attitudes toward T1DM (P = 0.02).

CONCLUSION

The present study revealed moderate knowledge, favorable attitudes, and poor practices related to T1DM among school teachers in Jeddah. It is crucial for policymakers to provide school teachers with training for necessary diabetes care for diabetic students.

Ultra-high-performance liquid chromatography-tandem mass spectrometry analysis of serum metabolomic characteristics in people with different vitamin D levels

Vitamin D is a fat-soluble vitamin with multiple functions. However, the metabolism of people with different vitamin D concentrations is still unclear. Herein, we collected clinical data and analysed the serum metabolome of people with 25-hydroxyvitamin D (25[OH]D) ≥40 ng/mL (A), 30 ng/mL ≤25(OH)D <40 ng/mL (B) and 25(OH)D <30 ng/mL (C) by the ultra-high-performance liquid chromatography-tandem mass spectrometry method. We found that haemoglobin A1c, fasting blood glucose, fasting insulin, homeostasis model assessment of insulin resistance and thioredoxin interaction protein were enhanced, while HOMA-β was reduced with the decrease of 25(OH)D concentration. In addition, people in the C group were diagnosed with prediabetes or diabetes. Metabolomics analysis showed that seven, thirty-four and nine differential metabolites were identified in the groups B vs A, C vs A and C vs B, respectively. Metabolites associated with cholesterol metabolism and bile acid biosynthesis, such as 7-ketolithocholic acid, 12-ketolithocholic acid, apocholic acid, N-arachidene glycine and d-mannose 6-phosphate, were significantly upregulated in the C group compared with the A or B groups. In conclusion, the disorder of vitamin D metabolism may be related to cholesterol metabolism and bile acid biosynthesis. This study provided a basis for exploring the possible mechanism leading to abnormal vitamin D metabolism.

Experiences and needs of Saudi mothers when a child or adolescent is diagnosed with type 1 diabetes mellitus: a qualitative study

Aim

To explore the experiences of Saudi mothers with children or adolescents who have Type 1 diabetes mellitus at time of diagnosis.

Background

The Kingdom of Saudi Arabia (KSA) has one of the highest incidence rates of Type 1 diabetes mellitus in children and adolescents in the world. Few studies have considered the most appropriate methods of support for parents in the KSA and none report the experiences of Saudi mothers.

Design

Phenomenological inquiry.

Method

Qualitative interviews were conducted with 11 Saudi mothers and data were analysed following Giorgi’s 5-step method.

Results

The lived experiences of Saudi mothers coalesced around three overarching themes and eight subthemes: 1. In the dark (mother’s instinct, challenges of diagnosis phase, cultural reflections); 2. Empowerment (methods of support, mother’s health and wellbeing); 3. Coping and acceptance (stigma and cultural perceptions, coping strategies, transformation and adaptation).

Conclusions

Effective interventions delivered in other countries to support mothers may be effective in the KSA. However, the central role that Saudi mothers play in the management of their child’s condition, and the place of Islam in Saudi society, indicate the need for customized methods of support that take into account psychosociocultural needs of both mother and child.

Cathelicidin as a marker for subclinical cardiac changes and microvascular complications in children and adolescents with type 1 diabetes

OBJECTIVES

To detect cathelicidin levels in pediatric patients with type 1 diabetes (T1D) as a potential marker for diabetic vascular complications and to assess its relation to diastolic dysfunction as an index for subclinical macrovasculopathy.

METHODS

Totally, 84 patients with T1D were categorized into three groups; newly diagnosed diabetes group (28 patients with a mean age of 12.38 ± 1.99) years, T1D without microvascular complications group (28 patients with a mean age of 13.04 ± 2.27), and T1D with microvascular complications group (28 patients with a mean age of 13.96 ± 2.30). Patients were evaluated using serum cathelicidin levels and echocardiography.

RESULTS

Total cholesterol, microalbuminuria, and cathelicidin levels were significantly higher in patients with microvascular complications when compared to the other two groups (p<0.001). Additionally, carotid intima-media thickness (CIMT) echocardiography values and diastolic functions were significantly higher in patients with complications (p<0.001). Cathelicidin was positively correlated to the duration of diabetes (r=0.542, p<0.001), total cholesterol (r=0.346, p=0.001), recurrence of hypoglycemia (r=0.351, p=0.001), recurrence of diabetes ketoacidosis (r=0.365, p=0.001), CIMT (r=0.544, p<0.001), and E/A values (r=0.405, p<0.001).

CONCLUSIONS

Serum cathelicidin levels can be used as an early marker for the occurrence and progression of vascular complications in patients with T1D.

Prevalence of diabetic retinopathy in the Eastern Mediterranean Region: a systematic review and meta-analysis

Objectives

Individual studies in the Eastern Mediterranean Region (EMR) have shown the high prevalence of diabetic retinopathy. We conducted a meta-analysis to yield an estimate of the prevalence of diabetic (type 1 and 2) retinopathy in the EMR. Additionally, we explored its potential modulators.

Methods

Two-step screening of relevant articles published from 1 January 2000 to 13 December 2019 was carried out. An estimation of summary proportions, subgroup analysis, meta-regression, and publication bias assessment were performed.

Results

One hundred nine articles were included in the meta-analysis, involving 280,566 patients. The prevalence of diabetic retinopathy was 31% (95% confidence interval [CI] = 28, 33). The highest and lowest diabetic retinopathy prevalence rates were observed in low human development index (HDI) countries (63.6; 95% CI = 52.4, 74.0) and very high HDI countries 22.6 (95% CI = 20.5, 24.7), respectively.

Conclusions

The prevalence of diabetic retinopathy is high in the EMR. Our results provide important information for diverse healthcare surveillance systems in the EMR to implement the modifiable risk factors, diabetes screening to decrease undiagnosed diabetes, early detection of retinopathy, and proper diabetes care to decrease untreated diabetes.

Time to first optimal glycemic control and its predictors among type 1 diabetic children in Bahir Dar city public referral hospitals, North West Ethiopia: a retrospective follow up study

Background

Recognizing the level of glycemic control of a client is an important measure/tool to prevent acquiring complications and risk of death from diabetes. However, the other most important variable, which is the time that the patient stayed in that poor glycemic level before reaching optimal glycemic control, has not been studied so far. Therefore, this study aim to estimate time to first optimal glycemic control and identify predictors among type 1 diabetic children in Bahir Dar city public referral hospitals, Northwest, Ethiopia, 2021.

Methods

A Retrospective cohort study was conducted at Bahir Dar city public referral hospitals among a randomly selected sample of 385 patients with type 1 diabetes who were on follow up from January 1, 2016 to February30, 2021.Data were collected by using a data abstraction tool and then entered into Epi-data version 4.6 and exported into STATA 14.0 statistical software. Descriptive statistics, Kaplan Meier plots and median survival times, Log-rank test and Cox-proportional hazard regression were used for reporting the findings of this study. After performing Cox-proportional hazard regression, model goodness-of-fit and assumptions were checked. Finally, the association between independent variables and time to first optimal glycemic control in months was assessed using the multivariable Cox Proportional Hazard model and variables with a p-value < 0.05 were considered as statistically significant.

Results

Median survival time to first optimal glycemic control among type 1 diabetic clients was 8 months (95%CI: 6.9–8.9). The first optimal glycemic achievement rate was 8.2 (95%CI: 7.2–9.2) per 100 person/month observation. Factors that affect time to first optimal glycemic control were age > 10–14 years (AHR = 0.32;95%CI = 0.19–0.55), increased weight (AHR = 0.96;95%CI = 0.94–0.99), having primary care giver (AHR = 2.09;95%CI = 1.39–3.13), insulin dose (AHR = 1.05;95%CI = 1.03–1.08), duration of diabetes ≥4 years (AHR = 0.64;95%CI = 0.44–0.94), adherence to diabetic care (AHR = 9.72;95%CI = 6.09–15.51), carbohydrate counting (AHR = 2.43;95%CI = 1.12–5.26), and comorbidity (AHR = 0.72;95%CI = 0.53–0.98).

Conclusion

The median survival time to first optimal glycemic control in this study was long. Age, weight, primary care giver, insulin dose, duration of diabetes, adherence, and carbohydrate counting, including history of comorbidity were determinant factors. Giving attention for overweight and comorbid illness prevention, increasing either the dose or frequency of insulin during initial treatment; counseling parent (for both the mother and father) about adherence to diabetic care focusing on insulin drugs and how to audit their children’s diet as prescription helps to reduce the length of glycemic control.

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.

Factors Affecting Glycemic Control among Saudi Children with Type 1 Diabetes Mellitus in Aseer Region, Southwestern Saudi Arabia

Glycemic control in children with type 1 diabetes mellitus (T1DM) is affected by many factors that may be influenced by their lives and community. To identify the factors associated with glycemic control among children with T1DM in Aseer Region, southwestern Saudi Arabia, a cross-sectional interview study was conducted between 1 July and 30 September 2021, with a representative sample of Saudi children aged between 6 months and 15 years with T1DM or their caregivers visiting the diabetes center at Aseer Region. Newly diagnosed cases (<12 months) were excluded from the study. The study included 171 T1DM pediatric patients aged between 18 months and 15 years. The glycated hemoglobin (HbA1c) level ranged between 6.10% and 15.10% (mean HbA1c = 10.39% ± 1.86%). High HbA1c levels (≥7.5%) were observed in most patients (94.7%). Only two significant factors were found: (1) use of carbohydrate counting; 81.8% of children using carbohydrate counts had high HbA1c levels, compared to 96.6% of children not using carbohydrate counts (p = 0.017), and (2) duration of the disease; 91.5% of children with disease duration of ≤3 years had high levels of HbA1c, compared to 98.7% of children with disease duration exceeding 3 years (p = 0.035). Most children with T1DM in Aseer Region had poor glycemic control. Only two factors were associated with better glycemic control: shorter disease duration and use of carbohydrate counting. Therefore, advising diabetic patients to be on a carbohydrate counting program might improve DM control.

The Prevalence of Associated Autoimmune Diseases Among Adults With Type 1 Diabetes Mellitus: A Cross-Sectional Study

Background

The relationship between type 1 diabetes mellitus (T1DM) and other autoimmune diseases has been known; however, the actual prevalence in the adult population nor clinical symptoms has not been determined locally.

Objectives

We aim to determine the prevalence of associated autoimmune diseases (Hashimoto’s thyroiditis, celiac disease (CD), and adrenal insufficiency (AI)) and evaluate the most reporting symptoms and glycemic control assessment, as well as microvascular complications and hypoglycemia episodes.

Methods

A cross-sectional study of 251 patients with T1DM at the diabetic clinic of King Abdulaziz Medical City in Riyadh (KAMC-RD), Saudi Arabia, was conducted. Autoimmune serologies including thyroid peroxidase (TPO) antibody and tissue transglutaminase IgA (tTG-IgA) antibody were checked with hormonal studies such as thyroid-stimulating hormone (TSH), morning serum cortisol, and short Synacthen test (SST) with duodenal biopsy results all were reviewed if present. Patients were directly interviewed to evaluate for the most common symptoms (including hypoglycemia episodes) for the preceding two weeks. Glycemic control was assessed by measuring glycated hemoglobin (HbA1c). Microvascular complications (i.e., nephropathy and retinopathy) were estimated by looking at the urine albumin/creatinine ratio (ACR) besides the ophthalmology’s visit notes.

Results

The mean age was 26.3 ± 7.7 years, and the mean duration of diabetes at the time of data collection was 12.2 ± 7.6 years, whereas the mean HbA1c was 8.9% ± 1.8%. The prevalence of hypothyroidism was 16.3%, and TPO positivity was discovered in 58.6% of the tested patients (n = 70) with equal prevalence among both genders (p = 0.685). tTG-IgA were noticed among 16.4% of the patients (n = 164) without significant difference among gender. Serum cortisol test was performed among 128 patients; 28.1% had suboptimal levels, and 5.5% were deficient. Only four patients (n = 15) had suboptimal responses after SST. Nervousness and anxiety (p < 0.001), fatigue with weakness (p = 0.018), weight gain (p = 0.017), and cold intolerance (p = 0.005) were noted, which were statistically significantly higher among females. Weight gain was statistically significantly higher among the age group of >30 years (p = 0.036). For microvascular complication screening, ACR was collected in 199 (79.2%) participants, with a mean of 27.7 ± 155.9 mg/mmol. Only 10 (5%) patients had microalbuminuria, and 16 (8%) had macroalbuminuria; it was correlated significantly with diabetes duration (p = 0.045). A total of 132 (52.8%) patients were seen by ophthalmology, 28 (21.4%) had nonproliferative diabetic retinopathy (NPDR), and 10 (7.6%) has proliferative diabetic retinopathy (PDR) that significantly correlated with the duration of diabetes (p = 0.027). During patient interviews, 187 (74.5%) reported symptomatic hypoglycemia events that correlated significantly with glycemic control (p = 0.029).

Conclusion

Autoimmunity in Saudi adults with type 1 diabetes mellitus was significant with equal prevalence among both genders and age groups with no or slight difference. Clinical manifestations of autoimmunity were higher in women. Diabetes chronicity and poor glycemic control were the major complications; therefore, early glycemic control is advocated. Regular screening for autoimmunity and its complications is recommended for type 1 diabetic patients. Autoimmunity was found almost similar to previous literature.

A Pattern of Lipid Profile Among Saudi Adults With Type 1 Diabetes Mellitus in a Tertiary Hospital: A Retrospective Study

OBJECTIVE

Dyslipidemia is prevalent in adults living with type 1 diabetes, and it can worsen the presentation of microvascular complications such as retinopathy. This study aims to identify the pattern coupled with the frequency of dyslipidemia in diabetic adults who followed up at different clinics in King Abdulaziz Medical City, Riyadh, and evaluate the associations with demographic and clinical characteristics.

METHODS

A cross-sectional, retrospective chart review study of 514 adults with type 1 diabetes was conducted in a tertiary health care facility in the central region of Saudi Arabia. Demographics were retrieved by using the implemented electronic medical records. Fasting lipid profile, glycated hemoglobin (HbA1c), and thyroid-stimulating hormone (TSH) levels were checked for all subjects.

RESULTS

Five hundred and fourteen (514) subjects aged 18-65 years were studied (mean age: 26.1 ± 7.1 years). There were 318 (62%) females in the sample, and their mean age was significantly different from the mean age of males (p = 0.01). The mean duration of having diabetes was 12.8 ± 6.9 years. The prevalence of lipid abnormalities included abnormal low-density lipoprotein (LDL) (70%), hypercholesterolemia (23%), abnormal high-density lipoprotein (HDL) (8%), and hypertriglyceridemia (5%). Abnormal HDL was significantly higher in males than in females (p=<0.001). There were no statistically significant differences in the prevalence of other lipid abnormalities between the two genders and the age group < or ≥ 25 years. There was no statistically significant difference in the mean of the tested lipids levels between the two genders. One hundred and forty-three (143) (27.8%) patients had more than one abnormal lipid condition. A statistically significant difference was observed in the mean HbA1c between males and females (p=0.001). Otherwise, there was no significant association of lipid abnormalities with gender, age, diabetes duration, and weight.

CONCLUSION

The most prevalent lipid abnormality was high LDL cholesterol. Nearly a third of the tested individuals had more than one lipid abnormality. Furthermore, poor glycemic control was linked to abnormal lipid profiles. Consequently, local programs must aim to screen and intervene early to delay and prevent future severe vascular complications related to non-treated dyslipidemia.

Burden of type 1 diabetes mellitus in the North Africa and Middle East Region, 1990-2019; findings from the global burden of disease study

AIMS

We aimed to report the burden of type 1 diabetes mellitus (T1DM) in the North Africa and Middle East region and its 21 countries from 1990 to 2019.

METHODS

Information related to incidence, prevalence, mortality, disability-adjusted life-years (DALYs), and years lived with disability (YLDs) of T1DM was acquired from the 2019 Global Burden of Disease study. The burden was estimated by sex, age groups, and socio-demographic index (SDI) in 21 countries.

RESULTS

Over the past 30 years, regional incidence, prevalence, mortality, and DALYs of T1DM increase by 188.7%, 304.8%, 43.7%, and 71.6%, respectively. While the age-standardized incidence and prevalence rates increased by 84% and 91%, the mortality and DALYs rates decreased by 34% and 13%. During these years, the contribution of YLDs to total DALYs increased considerably (from 17% to 42%). The highest increase in the incidence and prevalence rates occurred in high SDI countries. Moreover, the Mortality to Incidence Ratio (MIR) decreased in the region countries.

CONCLUSIONS

Despite progress made in diabetes care, there is a persistently increasing burden of T1DM in the region countries. This indicates that T1DM is still one of the major health challenges in the region countries, especially in high SDI Arab countries.

Glycemic Variability in Type 1 Diabetes Mellitus Saudis Using Ambulatory Glucose Profile

Background

Glucose variability (GV) is a common and challenging clinical entity in the management of people with type 1 diabetes (T1DM). The magnitude of GV in Saudi people with T1DM was not addressed before. Therefore, we aimed to study GV in a consecutive cohort of Saudis with T1DM.

Methods

We prospectively assessed interstitial glucose using FreeStyle^® Libre flash glucose monitoring in people with TIDM who attended follow-up in the diabetes clinics at King Fahad Medical City between March and June 2017. Glycemia profile, standard deviation (SD), coefficient of variation (CV), mean of daily differences (MODD), and mean amplitude of glucose excursion (MAGE) were measured using the standard equations over a period of 2 weeks.

Results

Fifty T1DM subjects (20 males) with mean age 20.2 ± 6.1 years and mean fortnight glucose 192 ± 42.3 mg/dl were included. The mean SD of 2-week glucose readings was 100.4 ± 36.3 mg/dl and CV was 52.1% ± 13%. Higher levels of glucose excursions were also observed. MODD and MAGE were recorded as 104.5 ± 51.7 and 189 ± 54.9 mg/dl, respectively which is 2 to 4 times higher than the international standards. Higher MODD and MAGE were observed on weekends compared to weekdays (111.3 ± 62.1 vs 98.6 ± 56.2 mg/dl and 196.4 ± 64.6 vs 181.7 ± 52.4 mg/dl, respectively; P ⩽ .001).

Conclusion

Higher degree of glycemic variability was observed in this cohort of TIDM Saudis. Weekends were associated with higher glucose swings than weekdays. More studies are needed to explore these findings further.

Association Between Knowledge of Hypoglycemia and Likelihood of Experiencing Hypoglycemia Among Patients with Insulin-Treated Diabetes Mellitus

PURPOSE

This study aimed to evaluate the association between a patient's knowledge about hypoglycemia and the likelihood of experiencing hypoglycemia.

PARTICIPANTS AND METHODS

This cross-sectional study used a structured questionnaire to survey a representative sample of 429 adult males with insulin-treated diabetes mellitus (ITDM) in Saudi Arabia.

RESULTS

The main factors associated with increased risk of hypoglycemia included (a) a premixed insulin regimen, (b) a long duration of insulin treatment, (c) the use of oral hypoglycemic agents, and (d) a high hypoglycemia knowledge score. Insulin as a treatment modality directly affects the development of hypoglycemia among ITDM patients. Sweating is the most prevalent clinical manifestation among ITDM patients with hypoglycemia and could be an early indicator of hypoglycemia. Earlier detection of hypoglycemic signs may ultimately improve quality of life in ITDM patients.

CONCLUSION

This research highlights the importance of healthcare providers educating ITDM patients about hypoglycemia. Furthermore, our results emphasize the urgent need to establish an educational program about hypoglycemia. ITDM patients are encouraged to learn more about hypoglycemia to help prevent future hypoglycemic attacks.

Assessment of self-monitoring of blood glucose in type 1 diabetic children and adolescents and its influence on quality of life: practice and perspective

Background

Self-monitoring blood glucose (SMBG) includes an assessment of the capillary glucose concentration as well as the interpretation of and responding to the readings. The purpose of this study was to assess patients’ compliance to self-monitoring blood glucose (SMBG), identify factors and barriers that affect it, and to correlate performance of SMBG to blood glucose monitoring and patients’ quality of life. Three hundred and thirty children and adolescents with type 1 diabetes were subjected to the following: (1) an interview pre-structured questionnaire which included personal, medical history, and details about SMBG; (2) Questionnaire about Quality of Life Index (Diabetes Version-III) by Ferrans and Powers for patients aging 10–16 years; and (3) glycated hemoglobin (HA1C) measurement.

Results

About 67% of the patients assessed their blood glucose 3 times per day, while 0.57% assessed blood glucose 7 times. The most influential factors affecting compliance of SMBG were the cost of strips and glucometers, the fear of pain and injection, psychological frustration, lack of availability of information to deal with high reading, and the absence of motivation for doing regular SMBG.

The more the frequency of SMBG daily, the better the HA1C of the patients (p < 0.01).

Adolescent patients aged 10–16 years who have more frequent SMBG and those with less HA1C have significant better quality of life (p < 0.05).

Conclusions

More frequent SMBG practice was associated with better glycemic control and better quality of life. Patients’ compliance is influenced by several factors which affect their frequency of SMBG.

The Epidemiology of Celiac Disease in the General Population and High-Risk Groups in Arab Countries: A Systematic Review

Background and Aims

Celiac disease (CD) is possibly the most common autoimmune disorder, which may lead to dietary problems in the Arab region. This paper is aimed at exploring the epidemiology of the celiac disease in Arab countries, including its prevalence, associated risk factors, and clinical patterns.

Methods

An extensive search of the literature was conducted from electronic databases such as PubMed, Embase, and Google Scholar. In total, 134 research papers were retrieved. We extracted studies published from January 1996 to December 2019. Our search was limited to studies published in English. Findings. The review included 35 studies with 22,340 participants from 12 countries and demonstrated a wide variation in the prevalence of CD. The highest prevalence among the general population (3.2%) was reported in Saudi Arabia, and the lowest (0.1%) was reported in Tunisia. Women demonstrated a higher prevalence of celiac disease relative to men. The peak age at diagnosis fell between 1 and 3 years and 9-10 years. Most studies focused on type 1 diabetes. Children with type 1 diabetes have a higher prevalence of CD (range from 5.5% to 20%), while the prevalence of CD in Down's syndrome patients was 1.1% and 10.7% in UAE and Saudi Arabia, respectively. Other autoimmune diseases associated with CD are thyroid disease and irritable bowel disease. The most widely recognized clinical presentation was an inability to flourish and poor weight gain, followed by short stature, abdominal pain, abdominal distension, bloating, and chronic diarrhea.

Conclusion

The prevalence of the celiac disease in Arab countries varies with sex and age. However, we found that celiac disease presented similar clinical characteristics independent of the geographic region. Longitudinal population-based studies are needed to better identify the true burden and determinants of celiac disease.

Impact of Socioeconomic Characteristics on Metabolic Control in Children with Type 1 Diabetes in a Developing Country

OBJECTIVE

Adequate glycemic control in children with type 1 diabetes reduces the risk of future complications. Identifying factors affecting haemoglobin A1c (HbA1c) is crucial to management of metabolic control. We aimed to identify possible socioeconomic predictors of poor metabolic control this patient group in Jordan, a developing country with limited resources.

METHODS

Medical charts of children with type 1 diabetes attending the pediatric endocrine clinics in two major diabetes centers were reviewed. HbA1c ≥7.5% (58 mmol/mol) was considered to reflect poor metabolic control. Logistic regression analysis was performed to identify predictors of poor glycemic control. The association between socioeconomic characteristics and metabolic control was evaluated using multiple correspondence analysis (MCA).

RESULTS

Two hundred and fifty-nine children were enrolled in the study. One fifth of the patients (20.5%) achieved HbA1c <7.5%. Patients with dietary non-compliance [odds ratio (OR): 3.533, confidence interval (CI): 1.803 - 6.926; p<0.001], and those who were overweight (OR: 3.869, CI: 1.218 - 12.294; p=0.022) were more likely to have poor metabolic control. Children whose mothers had a bachelor’s degree or higher were less likely to have poor metabolic control compared to children whose mothers had only elementary education (OR: 0.241, CI: 0.079 - 0.734; p=0.012). MCA revealed an association between low socioeconomic status and poor metabolic control. Children with deceased mothers had significantly higher HbA1c of 10.6±1.86% compared to an average of 8.7±1.45% for the rest of participants (p=0.005).

CONCLUSION

Low socioeconomic status, lower levels of maternal education and maternal death were associated with poor metabolic control. Identifying children with these risk factors might play an important role in optimizing metabolic control and provide better diabetes care.

Pediatric diabetes in Saudi Arabia: Challenges and potential solutions. A review article

Diabetes in children has increased globally, and the World Health Organization ranks Saudi Arabia 7th in prevalence and 5th in incidence of type 1 diabetes (T1D). Type 2 diabetes (T2D) in children and adolescents has been identified in Saudi Arabia but its prevalence is still unknown. Despite advances in diabetes management including new insulins, insulin delivery systems, glucose monitoring and easy access to media for disease awareness, diabetes in children continues to be challenging in many aspects. Problems include delayed diagnosis, suboptimal glycemic control, early and late disease complications, transition from pediatric to adult care and raising of obesity and T2D, poor psychological and school support. This review summarizes the pediatric and adolescent diabetes studies in Saudi Arabia to date and explores the country-specific treatment challenges and potential solutions.

Audit of glycemic control in patients with type 1 diabetes referred to a pediatric clinic in a specialized center in Kuwait

INTRODUCTION

Intensive glycemic control reduces the risk of microvascular and macrovascular complications. Furthermore, optimal glycemic control is essential for normal growth and development. Thus, there is a need to monitor and evaluate glycemic control in patients with type 1 diabetes (T1D). Our aim was to audit glycemic control in patients with T1D in a specialized center as per the Society of Pediatric and Adolescent Diabetes (ISPAD) Hemoglobin A1C (HbA1C) target recommendations published in 2014.

METHODS

This is a retrospective cross-sectional study reporting on glycemic control (HbA1C) of patients younger than 21 years of age and with T1D treated at Dasman Diabetes Institute (DDI) between January 2013 and December 2015.

RESULTS

A total of 470 patients with T1D (250 males and 220 females) were included. Only 53 (11.3%) patients met the ISPAD target for optimal glycemic control with HbA1C < 7.5% (58 mmol/mol). Older age was positively associated with poor glycemic control (p = 0.001) while Continuous Subcutaneous Insulin Infusion (CSII) therapy was negatively associated with poor glycemic control, adjusted Odds Ratio (OR) 0.33 (95% confidence interval (CI): 0.16-0.66) for CSII and adjusted OR 0.42 (95% CI: 0.27-0.64) for shifting to CSII (p < 0.001).

CONCLUSION

Achieving optimal glycemic control is a significant challenge for young patients with T1D. Glycemic control goals should be individualized to achieve such goals safely, realistically and with a better quality of life for patients with T1D.

Celiac disease in type 1 diabetes mellitus in the Kingdom of Saudi Arabia. Characterization and meta-analysis

Objectives:

To characterize and meta-analyze the pertinent studies concerning celiac disease (CD) among patients with type 1 diabetes mellitus (T1DM) in the Kingdom of Saudi Arabia.

Methods:

Data (from the relevant articles) were analyzed using both the Statistical Package for Social Sciences, version 20 (IBM Corp., Armonk, NY, USA) program and the comprehensive meta-analysis (CMA) program. This study was conducted between March and July 2018 at King Abdulaziz University, Jeddah, Kingdom of Saudi Arabia. Written ethical approval was not obtained because this study was a retrospective literature review and analysis.

Results:

The prevalence of seropositive-CD was 15.88% with high heterogeneity (I²=84.0), while the prevalence of biopsy-proven CD was 12% with high heterogeneity (I²=82.7). Anti-transglutaminase was used in 7 of the 8 studies; alone in 4; with endomysial antibodies in 2; and with antigliadin antibodies (AGA) in one. In the remaining study, antireticulin antibodies was used with AGA. The age of the involved patients ranged from 8 months to 50 years old.

Conclusion:

The prevalence of biopsy-proven CD among T1DM patients in Kingdom of Saudi Arabia (12.0%) was double the global prevalence (6.0%), and much higher than the normal Saudi population (1.4%). The female-to-male ratio (2:1) of CD patients in T1DM was the same as in the normal population in Kingdom of Saudi Arabia. No significant difference was detected between the reported serologically-proven rates and the reported biopsy-proven rates (p=0.093).

Celiac disease among at-risk individuals in Saudi Arabia

OBJECTIVES

To perform a meta-analysis for celiac diseases (CD) among at-risk populations in Kingdom of Saudi Arabia (KSA), as well as a comparison with our previously reported meta-analysis in the normal population.

METHODS

In March 2018, at King Abdulaziz University,  Jeddah, KSA we commenced a retrospective comprehensive database and journal search for CD among at-risk populations in SA. Data from each of the relevant articles were analyzed using the  Statistical Package for Social Science Version 20 (Armonk, NY: IBM Corp.). and the comprehensive meta-analysis program (CMA). The collected data were part of a retrospective literature review and analysis. Thus, a written ethical approval was not obtained before commencing the study. Results: Sixteen articles were found covering type-1 diabetes mellitus (DM), short stature (SS), and down syndrome (DS). Ages 1-50 years . The prevalence of seropositive-CD was 15.6% with high heterogeneity (I2=80.353), while prevalence of biopsy-proven CD was 10.6% with high heterogeneity (I2=73.359). Another article reported the CD prevalence in the at-risk population as 18.4% for the seroprevalence and  6.9% for the biopsy-proven CD. Anti-transglutaminase (anti-tTG) was used in 12 studies; in the remaining 4 studies (EMA in 2, ARA with AGA in one and no details given in one study). Conclusion: Both the prevalence of biopsy-proven CD (10.6%) and seroprevalence (15.6%) were higher than those we previously reported in the normal population (1.4% and 2.7%). The female-to-male ratio (1.9/1) of CD patients was the same in normal and at-risk populations in SA. Meta-analysis for prevalence of CD in DM, SS, and DS separately in SA is recommended.

Personal and Clinical Predictors of Poor Metabolic Control in Children with Type 1 Diabetes in Jordan

BACKGROUND

Achieving adequate metabolic control in children with type 1 diabetes is important in slowing the progression of future microvascular and macrovascular complications, but still it is a universal challenge. We aim to investigate possible factors associated with poor metabolic outcomes in Jordan as an example of a country with limited resources.

METHODS

This is a retrospective chart review study of children with type 1 diabetes. Several clinical and personal characteristics were tested for association with metabolic control reflected by HbA1c levels. Linear logistic regression analysis was used to evaluate possible predictors of metabolic control. One-way ANOVA analysis was used to detect significant differences in HbA1c between categories.

RESULTS

Significant predictors of metabolic control were found. A one-year increase in age led to an increase in HbA1c by 0.053% (P = 0.044). A decline in HbA1c levels was predicted in children who have precise amount of carbohydrates or who are receiving insulin at school (-0.46% (P = 0.014) and -0.82% (P = 0.004), respectively). When family members other than mothers decided the insulin dose, the HbA1c level increased by 0.74% (P = 0.005).

CONCLUSION

Poor metabolic control was associated with age, dietary noncompliance, not receiving insulin at school, and absence of direct mother care. Our study is one of the few studies from Middle East evaluating predictors of metabolic control. Global research studies help in giving universal insight towards developing more effective multidisciplinary team approach for diabetes care and education.

Type 1 Diabetes Mellitus in Saudi Arabia: A Soaring Epidemic

Type 1 diabetes mellitus (T1DM) is quite prevalent in the world, with a proportion of 1 in every 300 persons and steadily rising frequency of incidence of about 3% every year. More alarmingly, the incidence of T1DM among infants is also increasing, with children as young as 6 months succumbing to it, instead of that at a rather established vulnerable age of around seven and near puberty, when the hormones antagonize the action of insulin. These reports pose a unique challenge of developing efficient T1DM management system for the young children. The Kingdom of Saudi Arabia (KSA) is the largest country in the Middle East that occupies approximately four-fifths of the Arabian Peninsula supporting a population of more than 33.3 million people, of whom 26% are under the age of 14 years. As per the Diabetes Atlas (8th edition), 35,000 children and adolescents in Saudi Arabia suffer from T1DM, which makes Saudi Arabia rank the 8th in terms of numbers of TIDM patients and 4th country in the world in terms of the incidence rate (33.5 per 100,000 individuals) of TIDM. However, in comparison with that in the developed countries, the number of research interventions on the prevalence, incidence, and the sociodemographic aspects of T1DM is woefully inadequate. In this review we discuss different aspects of T1DM in Saudi Arabia drawing on the published literature currently available.

Serum Vitamin D and Its Upregulated Protein, Thioredoxin Interacting Protein, Are Associated With Beta-Cell Dysfunction in Adult Patients With Type 1 and Type 2 Diabetes

OBJECTIVES

Diabetes mellitus is characterized by either complete deficiency of insulin secretion, as in type 1 diabetes, or decompensation of the pancreatic beta cells in type 2 diabetes. Both vitamin D (vitD) and thioredoxin interacting protein (TXNIP) have been shown to be involved in beta-cell dysfunction. Therefore, this study was designed to examine vitD and TXNIP serum levels in patients with diabetes and to correlate these levels with beta-cell function markers in both types of diabetes.

METHODS

The routine biochemical parameters and the serum levels of vitD and TXNIP were measured in 20 patients with type 1 diabetes and 20 patients with type 2 diabetes. The levels were then compared to those of 15 healthy control volunteers. Insulin, C-peptide and proinsulin (PI), vitD and TXNIP were measured by ELISA. Beta-cell dysfunction was assessed by homeostatic model assessment (HOMA-beta), proinsulin-to-C-peptide (PI/C) and proinsulin-to-insulin (PI/I) ratios. Correlations among various parameters were studied.

RESULTS

Patients with type 1 diabetes had significantly lower HOMA-beta, vitD and TXNIP levels; however, they had higher PI/C levels than the control group. Meanwhile, patients with type 2 diabetes had significantly higher C-peptide, proinsulin, PI/C, HOMA-insulin resistance (HOMA-IR) and lower HOMA-beta and vitD levels, with no significant difference in TXNIP levels as compared to the control group. In addition, vitD was significantly correlated positively with HOMA-beta and TXNIP and negatively with PI, PI/C, PI/I and HOMA-IR. TXNIP correlated positively with HOMA-beta and negatively with PI/C.

CONCLUSIONS

Our data showed that vitD and TXNIP were associated with different beta-cell dysfunction markers, indicating their potential abilities to predict the beta-cell status in people with diabetes.

Pattern of thyroid, celiac, and anti-cyclic citrullinated peptide autoantibodies coexistence with type 1 diabetes mellitus in patients from Southwestern Saudi Arabia

Objectives:

To investigate the seroprevalence of coexisting autoantibodies among type 1 diabetes mellitus (T1DM) patients, and to look for possible correlations with age at diagnosis, diabetes duration, and glycemic control.

Methods:

This is a cross-sectional study conducted at Aseer Central Hospital, Abha, Kingdom of Saudi Arabia from March 2013 to June 2014. A total of 202 T1DM patients were screened for serum anti-thyroglobulin (TG), anti-thyroid peroxidase (TPO), anti-tissue transglutaminase (aTTG), anti-endomysial (EMA), and anti-cyclic citrullinated peptide (anti-CCP) antibodies along with glycated hemoglobin, and biometric data.

Results:

From the 202 T1DM patients (96 males, and 106 females) (mean age: 11.3 years), 33 (16.3%) were positive for thyroid autoantibodies. Specifically, 19 (9.4%) were positive for TG and 25 (12.8%) were positive for TPO, and 11 were double positive. There were 21 (10.4%) patients that showed a double positive for both aTTG-IgA and EMA, and only one case of T1DM was positive for anti-CCP. No significant correlations were noticed between the presence of autoantibodies and the age at diagnosis, diabetes duration, body mass index, and glycemic control.

Conclusion:

The prevalence of thyroid and celiac disease autoantibodies is high among T1DM patients, while anti-CCP remains low and might be weakly associated with T1DM in the southwestern region of Saudi Arabia. No significant correlation between the age at T1DM diagnosis, duration, and glycemic control, and the presence of autoantibodies was found.
