Demographic and clinical characteristics of type 1 diabetes mellitus in omani children - single center experience

The potential Association of Bisphenol A exposure and type 1 diabetes mellitus among Dakahlia Governorate's children sample, Egypt

Background

Bisphenol A (BPA) is an endocrine disrupter affecting glucose homeostasis.

Objectives

This study aimed to investigate BPA's relationship with Type 1 Diabetes Mellitus (T1DM) in Dakahlia Governorate's children, in Egypt.

Subjects materials and methods

The study had two parts: clinical and experimental. Clinical Study was conducted on 200 children, equally divided into control and T1DM groups. They underwent: demographic data, height, weight, body mass index, glycosylated HbA1C, random blood glucose, and urinary BPA measurements. Experimental Study was conducted on 60 adult albino rats. Rats were randomly divided into three equal groups: control group: received 0.5 mL of pure olive oil, group 1: received 20 mg/kg/day BPA, and group 2: received 100 mg/kg/day BPA orally for 6 weeks. Fasting and two hours postprandial glucose levels were measured at the beginning and end of the study. Histopathological examination and imaging study of the pancreas were done.

Results

In clinical study: HbA1C and random blood glucose levels in diabetic children showed a significant increase compared to control. Children in control group showed controlled HbA1C, while the T1DM group showed 86% with poor diabetic control. There was a significant increase in BPA level in the T1DM group compared to the control. Rats that received BPA showed a marked increase in fasting and two hours postprandial glucose levels, histopathological changes in the pancreas with more changes determined in the high dose group, and a significant decrease in the islets of Langerhans diameters with group 2 more affected.

Conclusion

So, BPA exposure could be considered a risk factor for T1DM in children.

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.

Frequency, Clinical Characteristics and Predictors of Ketoacidosis at Diagnosis of Type One Diabetes Mellitus in Children and Adolescents from Jordan

OBJECTIVE

Data regarding diabetic ketoacidosis (DKA) at diagnosis of type one diabetes (T1D) in developing countries are scarce. The aim of this study was to describe the frequency of DKA at the onset of T1D in children and adolescents in Jordan and to compare the clinical and biochemical characteristics between the group that presented with DKA and the group that did not.

METHODS

The records of 341 children and adolescents, less than sixteen years of age, who were diagnosed with T1D between 2015 and 2019 were evaluated retrospectively.

RESULTS

Of all the children diagnosed with T1D, 108 (31.7%) presented with DKA. The majority had mild or moderate DKA (38% and 33.3% respectively). Higher paternal education levels were associated with a lower probability of presenting with DKA (p=0.043). A family history of T1D had a protective effect on the occurrence of DKA (Odds ratio=2.138; 95% confidence interval=1.167-3.917, p=0.014). Patients with celiac disease and higher HbA1c levels were more likely to experience recurrent episodes of DKA, (p=0.004 and 0.011, respectively).

CONCLUSION

In Jordan, the rate of DKA at presentation of T1D remains high. Prevention campaigns are needed to increase diabetes awareness among the public and healthcare providers.

The Association of Human Leukocyte Antigens Complex with Type 1 Diabetes in the Omani Population

Objectives

Identification of the high risk alleles, genotypes and haplotypes of the human leukocyte antigens (HLA) in different populations is beneficial for understanding their roles in type 1 diabetes (T1D) pathogenesis and intervention practices. This study aimed to identify T1D-associated HLA gene alleles in the Omani population.

Methods

The present case-control study included 73 diabetic seropositive children (mean age 9.08 ± 3.27 years) attending the paediatric clinic at Sultan Qaboos University Hospital in Muscat, Oman, and 110 healthy controls. HLA-A, -B, -C, -DRB1 and -DQB1 genes were genotyped using a sequence-specific primer polymerase chain reaction (SSP-PCR).

Results

Two HLA class I alleles (B*08, B*58) and three class II alleles (DQB1*02, DRB1*03 and DRB1*04) were associated with T1D susceptibility, while one class I (B*51) and three class II (DQB1*05, DQB1*06 and DRB1*16) alleles were associated with T1D protection. HLA-DRB1*03 and DQB1*02 alleles showed the strongest risk association among all alleles. Six DRB1 residues (E⁹, S¹¹, S¹³, Y³⁰, V⁷⁰ and K⁷¹) were significantly associated with T1D susceptibility. Heterozygous genotypes, HLA-DRB1*03/*04 and DQB1*02/*03 were significantly associated with T1D susceptibility (P <0.0001, odds ratio [OR] = 63.21 and P = 0.02, OR = 3.63, respectively). Furthermore, a significant combined action of DRB1*03-DQB1*02 haplotype in T1D risk (P = 0.000176, OR = 15) and DRB1*16-DQB1*05 haplotype in protection (P = 0.0312, OR = 0.48) was detected.

Conclusion

Known HLA class II gene alleles are associated with T1D in Omani children.

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.

Sib-pair subgroup familial type 1 diabetes mellitus in children in the state of Qatar

Background

Type 1 diabetes is the most common type of diabetes mellitus (DM) in children. It can be sporadic in onset or cluster in families, which comprises parent-offspring and sib-pair subgroups. The risk of developing DM in first-degree relatives of affected individuals is 8–15 fold higher. There is limited data about familial DM from the Gulf region. This study aims to describe the clinical, biochemical and genetic characteristics of sib-pair familial type 1 diabetes in Qatar.

Methods

Every child with DM following up at Sidra Medicine was recruited. Data was collected regarding clinical features, family history, type 1 diabetes autoantibodies and whole genome sequencing was performed. Genetic analysis for MODY genes and HLA association analysis was conducted.

Results

44 families with sib-pair familial diabetes were identified. Of these, 2 families had 4 affected siblings and 5 families had 3 affected siblings. The majority are of Qatari ethnicity and the most common autoantibody was GAD65. The most common age of onset in the proband was 5–9 years while it was 10–14 years in subsequent siblings. The occurrence of DKA & HbA1c levels were lower in the second affected sibling. No relevant MODY gene variants were found. HLA analysis found 15 variants in at least 50% of the subjects. Most common were HLA-F*01*01*01G, HLA- DPA1*01*03*01G, HLA- DRB3*02*02*01G, HLA- E*01*01*01G & DRB4*03*01N.

Conclusions

The prevalence of sib-pair diabetes is 3.64%. The second affected siblings were older. MODY is unlikely and Class I and II HLA genes was present in sib-pair diabetes.

Genetics and Pathophysiology of Maturity-onset Diabetes of the Young (MODY): A Review of Current Trends

Single gene mutations have been implicated in the pathogenesis of a form of diabetes mellitus (DM) known as the maturity-onset diabetes of the young (MODY). However, there are diverse opinions on the suspect genes and pathophysiology, necessitating the need to review and communicate the genes to raise public awareness. We used the Google search engine to retrieve relevant information from reputable sources such as PubMed and Google Scholar. We identified 14 classified MODY genes as well as three new and unclassified genes linked with MODY. These genes are fundamentally embedded in the beta cells, the most common of which are HNF1A, HNF4A, HNF1B, and GCK genes. Mutations in these genes cause β-cell dysfunction, resulting in decreased insulin production and hyperglycemia. MODY genes have distinct mechanisms of action and phenotypic presentations compared with type 1 and type 2 DM and other forms of DM. Healthcare professionals are therefore advised to formulate drugs and treatment based on the causal genes rather than the current generalized treatment for all types of DM. This will increase the effectiveness of diabetes drugs and treatment and reduce the burden of the disease.

Pediatric Diabetic Retinopathy: Experience of a Tertiary Hospital in Oman

PURPOSE

The aim of this study is to describe the prevalence and clinical profile of pediatric diabetic retinopathy (DR) among Omani diabetic children and adolescents attending a tertiary care hospital.

METHODS

This retrospective cross-sectional study involved the record review of 216 diabetic children attending the diabetes retina clinic of the National Diabetes and Endocrine Centre in the period between June 2015 and November 2018. The retinal evaluation was conducted using direct ophthalmological examination and fundus photography. DR was graded using the Early Treatment DR Study criteria. The statistical analysis was performed using SPSS, version 20.

RESULTS

The prevalence of DR among the study sample was 3.7% (95% confidence interval: 1.2-6.2). Mild and moderate nonproliferative diabetic retinopathy was seen in 2.8% (6) and 0.9% (2) of patients, respectively. Diabetic maculopathy was observed in 2 (0.9%) cases. Diabetic ketoacidosis was seen in 33.8% of children at presentation. DR was significantly associated with age (P = 0.01), duration (P < 0.001), Type 1 diabetes mellitus (P = 0.01), dyslipidemia (P = 0.005), microalbuminuria (P = 0.001), glycated hemoglobin (P = 0.003), total cholesterol (P = 0.001), high-density lipoproteins (P = 0.001), low-density lipoproteins (P < 0.001), and albumin/creatinine ratio (P < 0.001).

CONCLUSIONS

This is the first study describing DR among the pediatric age group in Oman. This study reveals a relatively low prevalence of DR and maculopathy among the pediatric diabetic population. However, novel strategies are to be adopted at primary levels to achieve timely screening of diabetic children to enhance the early detection of DR.

Incidence of diabetic ketoacidosis in newly diagnosed type 1 diabetes children in western Saudi Arabia: 11-year experience

Background A wide range of reports on the incidence of diabetic ketoacidosis (DKA) at the onset of type 1 diabetes mellitus (T1DM) in children have been published worldwide. Reports from Saudi Arabia are limited. The aim of this study was to assess the incidence, clinical pattern and severity of DKA in children with newly diagnosed T1DM and the association of autoimmune conditions with initial DKA occurrence at King Abdulaziz Medical City - Jeddah. Methods This retrospective chart review was conducted during the period 2005-2015. All newly diagnosed T1DM children during the study period were investigated (n = 390). Data were collected on the demographic characteristics, body mass index (BMI), DKA severity, length of hospital stay and follow-up data on the type of diabetes therapy. Results The incidence of DKA among newly diagnosed T1DM pediatric patients was 37.7% (n = 147). Moderate and severe DKA cases were significantly higher among female children (p = 0.04). Patients diagnosed with DKA had lower BMI (20.87 ± 5.21) than their counterparts (p = 0.03). The median length of hospital stay was higher among severe DKA compared to moderate and mild cases (5.0, 4.5 and 4.0 days, respectively). Conclusions The incidence of DKA among newly diagnosed T1DM is still high compared to developed countries; however, it is relatively lower than previous reports in Saudi Arabia. Immediate interventions, such as awareness campaigns, are vital to reduce the burden of this preventable health sequela among children with DM.

Epidemiology of diabetic ketoacidosis in Arab patients with type 1 diabetes: a systematic review

AIMS

Diabetic ketoacidosis (DKA) is an acute and risky complication of type 1 diabetes. The aim of this study is to build the overall rate of DKA in Arab patients with type 1 diabetes in the 22 Arab nations. This is expected to tailor the healthcare approaches in Arab countries where attention is needed to save lives from the devastating consequences of DKA.

METHODS

The study here is a quantitative analysis of the articles indexed in four different scientific literature databases: Web of Science, PubMed, Science Direct and Scopus, from inception to June 2015. Arab patients with type 1 diabetes who presented with DKA have been captured. Key information was possible to extract for patients belong to only 12 Arab countries out of the 22 Arab patients.

RESULTS

Twenty-nine studies in 12 different Arab countries captured 4,688 type 1 diabetes patients with overall rates of 46.7% patients presented with DKA, ranging from a low of 17% in Egypt to a high of 100% in Morocco, Algeria and Tunisia.

CONCLUSION

This is the first descriptive quantitative study to determine the overall DKA rate in 46 years of studies in the Arab world of patients with type 1 diabetes; DKA rates were found to range from 17% to 100% with overall rate of 46.7%.
