[PMID: 39021682 PMCID: PMC11249991 DOI: 10.14744/semb.2024.56767] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 12/18/2023] [Revised: 01/26/2024] [Accepted: 02/08/2024] [Indexed: 07/20/2024]
Abstract
Objectives The aim of this study is to compare children diagnosed with type 1 diabetes mellitus (T1DM) with healthy controls in terms of some laboratory parameters and platelet indices. Methods This study is retrospective. We used glycated hemoglobin (HbA1c) values to classify patients as <7% (good) and ≥7% (poor). The platelet mass (PM) value was calculated from the hemogram data (PM=PLTxMPV). Results The study included a total of 87 patients who had been diagnosed with T1DM and 120 healthy participants. Fasting glucose, urea, creatinine, hemoglobin (HGB), red blood cell (RBC), mean platelet volume (MPV) and platelet distribution width (PDW) were significantly higher in the patient group than in the healthy control group. Platelet (PLT), plateletcrit (PCT) and PM were significantly lower in the poor glycemic control than in the good glycemic control and healthy groups. The PDW in the healthy control group was statistically significantly lower than in the good and poor glycemic control groups. In the group with poor glycemic control, there was a positive and significant correlation between the MPV and the level of HbA1c (r=0.401, p<0.05). Conclusion To sum up, our results show that the MPV and the PDW are significantly higher in children with T1DM than in healthy control. In the group with poor glycemic control, PLT levels were significantly lower than in the other two groups, leading to a decrease in PCT and PM levels. Further studies are needed to understand whether the decrease in PLT levels is due to the hyperactivity and rapid turnover of PLT.

The Role of Childhood Obesity in Early-Onset Type 2 Diabetes Mellitus: A Scoping Review. Cureus 2023; 15:e48037. [PMID: 38034219 PMCID: PMC10687489 DOI: 10.7759/cureus.48037] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 10/31/2023] [Indexed: 12/02/2023] Open
Abstract
Childhood obesity is a growing concern worldwide, with significant implications for public health. Of particular interest is its association with the early onset of type 2 diabetes mellitus in children. Exploring this relationship and identifying contributing factors may help strengthen understanding of this complex relationship. Factors such as family history, gender, and sedentary lifestyle, and poor dietary habits, insulin resistance in adipose tissue have been identified as significant contributors to early-onset type 2 diabetes. The rising prevalence of childhood obesity and its association with diabetes necessitates early interventions to mitigate this concerning trend and ensure a lasting impact on public health. This scoping review aims to investigate the relationship between childhood obesity and early-onset type 2 diabetes mellitus while also exploring other contributing factors. We employed a standardized framework for reviews to analyze relevant literature published in English between 2000 and 2021. Only primary research, systematic reviews, and meta-analyses addressing the association between childhood obesity and early-onset type 2 diabetes mellitus were included. The review adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) format. Out of the 3614 articles assessed, 17 were ultimately incorporated into this scoping review as they met the inclusion criteria. The majority of the literature primarily represented North American studies, with no inclusion of studies from South America. The findings from these studies have highlighted several factors contributing to type 2 diabetes mellitus development. Most of the studies associated obesity development with hypertension and unfavorable lipid profiles. It is important to acknowledge that these findings are derived from the available literature and may not encompass the entirety of research on childhood obesity and early-onset type 2 diabetes mellitus. Furthermore, the limited regional diversity in the selected studies may restrict the generalizability of these findings to other geographic regions. Additional research involving diverse populations is imperative for a comprehensive understanding of the link between childhood obesity and early-onset type 2 diabetes mellitus. Insulin resistance in adipose tissue among obese individuals contributes to the transition from obesity to type 2 diabetes mellitus. Notably, this transition occurs at approximately half the duration in obese youths compared to obese adults, where it typically takes around a decade. The increasing prevalence of childhood obesity and diabetes mellitus in high-income, low-income, and middle-income countries necessitate collective efforts to reduce the increasing rates of early-onset type 2 diabetes in children. This scoping review, therefore, seeks to underscore the importance of early interventions with regard to ensuring a lasting impact capable of extending into adulthood.

Abstract
Background Altered levels of many hematological parameters have been directly associated with diabetes in adults, while studies on children with type 1 diabetes mellitus are lacking. The aim of this study was to determine hematological indices in diabetic Bosnian children in comparison to healthy controls as well as to correlate their levels to blood glucose and hemoglobin A1c. Methods 100 healthy and 100 children with type 1 diabetes mellitus (age 1-18) were included in this study. Complete blood count, hemoglobin A1c, and glucose were tested. Results were analysed by IBM SPSS Statistics version 23. Results Significant differences (p<0.05) between healthy and diabetic children were found in relation to HbA1c, glucose, mean platelet volume, the number of white blood cells and erythrocytes, hematocrit, hemoglobin and MCH values. No gender differences or significant age differences were seen for hemoglobin, hematocrit, and MCV, while platelets, MPV, and MCH differed by age only in healthy children. When diabetic children were classified according to HbA1c levels, significant differences were seen for erythrocyte count and hematocrit value (p=0.013 and 0.019, respectively). The number of erythrocytes and white blood cells correlated significantly with HbA1c (p=0.037 and 0.027, respectively). Conclusions Lower levels of erythrocytes, hematocrit, and hemoglobin in diabetic compared to healthy children indicate possible development of anemia, while higher MCV, MCH, and MPV values indicate an alteration in erythrocyte morphology. Hematological indices could be a useful inexpensive tool in the diagnosis and follow up of type 1 diabetes in children.

[PMID: 30151912 DOI: 10.1111/ped.13687] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/22/2017] [Revised: 05/29/2018] [Accepted: 08/17/2018] [Indexed: 12/16/2022]
Abstract
BACKGROUND Type 1 diabetes mellitus (T1DM) is caused by autoimmune destruction of islet β-cells of the pancreas. There are overlapping phenotypes in a significant proportion of youth with type 1 and 2 diabetes. Thus, positive pancreatic autoantibodies are helpful to diagnose T1DM. Zinc transporter 8 antibody (ZnT8A) is a recently identified autoantibody in T1DM and no data on ZnT8A in the Thai population have been reported. The aim of this study was therefore to estimate the prevalence of ZnT8A in Thai juvenile-onset T1DM and to evaluate its diagnostic value relative to glutamic acid decarboxylase and insulinoma-2 antigen antibodies (GADA and IA2A). METHODS In this cross-sectional study, patients with T1DM diagnosed before age 15 years, and disease duration <10 years were enrolled. Serum ZnT8A, GADA, and IA2A were measured using commercial enzyme-linked immunosorbent assay kits. RESULTS The subjects consisted of 81 youths (30 boys, 51 girls) aged 12.3 ± 4.5 years with T1DM. The median diabetes duration was 3 years (range, 0-10 years). The prevalence of ZnT8A, GADA, and IA2A was 54.3%, 75.3%, and 45.7%, respectively. ZnT8A were detected in 16% of T1DM patients negative for both GADA and IA2A. A combination of ZnT8A, GADA and IA2A could detect 80.2% of patients with T1DM. Combined use of ZnT8A and GADA identified 100% of antibody-positive patients. CONCLUSION The prevalence of ZnT8A in Thai juvenile-onset T1DM appears to be higher than in previous studies from Asia. ZnT8A could replace IA2A as an autoimmunity marker in Thai pediatric T1DM patients, with better diagnostic performance.

Abstract
Abstract
Background: Reports on characteristics of pediatric diabetes in children from Southeast Asian countries are limited.
Objectives: To describe the clinical characteristics, prevalence, glycemic control, and current treatment regimens of diabetes in Thai children.
Materials and Methods: Data from 132 patients seen at our pediatric diabetes clinic at Chulalongkorn University during 2001−2013 were retrospectively reviewed.
Results: We found an increasing number of patients newly-diagnosed with type 1- (T1DM) or type 2- diabetes mellitus (T2DM). The overall proportion of T1DM was 69.7%, T2DM 23.4%, and other types 6.9%. Children with T1DM were younger at diagnosis, had higher initial glucose and glycated hemoglobin A1c (HbA1c), a lower body mass index z-score, lower C-peptide and insulin levels, and were more likely to have classic diabetes symptoms and ketoacidosis, compared with children with T2DM. Mixed diabetes phenotypes were found in about 12%−14% of these children. Glutamic acid decarboxylase and islet antigen-2 autoantibodies were found in 70% and 54% of T1DM patients, respectively, and not in T2DM patients. HbA1c in T1DM was 9.6 ± 2.2% total hemoglobin, and in T2DM was 7.9 ± 2.6%. There were no differences in HbA1c levels between different insulin regimens in the T1DM group.
Conclusion: The number of children with T1DM or T2DM has been increasing and there are overlapping phenotypes in a significant proportion of these children. Correct diagnosis requires clinical evaluation and monitoring of the clinical course. Further research is needed to determine the risk factors for the poor glycemic control found in children with T1DM.

Abstract
BACKGROUND AND PURPOSE Childhood obesity prevention (COP) should include increasing school nurse involvement. Measurements of school nurse perceptions influencing COP practices are limited. The purpose of this study is to evaluate the reliability and validity of 5 measures of school nurse COP practices and perceptions. METHODS A 70-item anonymous survey was completed by 171 Florida registered nurse (RN) school nurses and tested for reliability and validity. RESULTS Internal reliability was acceptable with Cronbach's alphas ranging from .81 to .94. Uncertain to adequate test-retest reliability was determined by correlation coefficients (r = .55-.78). Significant correlations (p < .05) based on hypothesized relationships provided moderate support for construct validity. CONCLUSIONS Results support use of these scales in research with targeted school nurse populations to promote COP practices.

Abstract
OBJECTIVE To determine whether measuring diabetes-associated autoantibodies (DAA) in pediatric new onset diabetes (NODM) can be restricted to patients with equivocal diabetes type. RESEARCH DESIGN AND METHODS Retrospective analysis of all patients with NODM admitted to Boston Children's Hospital from 1 October 2007 to 1 July 2013 who had measurement of DAA [glutamic acid decarboxylase, insulin, insulinoma-associated antigen 2 (IA-2)]. Data collection included initial diagnosis of diabetes type before DAA results and at follow-up. We used logistic regression to predict type 1 diabetes (T1D) and developed a clinical score to classify diabetes type. RESULTS Of 1089 patients (45.4% female, 76.7% White, age 10.6 ± 4.5 yr), initial diagnosis was 1021 (93.8%) T1D, 42 (3.9%) type 2 diabetes (T2D), and 26 (2.4%) other. Of 993 patients with clinical T1D, 78 (7.9%) were DAA-, and of 42 patients with clinical T2D, 12 (28.6%) were DAA+. Type of diabetes was reclassified at follow-up in less than 6% of patients. Data from a subset of 736 patients were used to develop a scoring system to predict T1D. Using weight z-score, age, and race, the scoring system had 91.7% sensitivity, 82% specificity, and a positive predictive value of 98.6%, and suggested DAA measurement was unnecessary in 85.3% of patients. Findings were similar in a validation cohort of 234 patients. CONCLUSIONS Application of a simple scoring system may reduce to ∼15% the number of DAA measurements needed to classify diabetes type, resulting in substantial cost savings. Clinical judgment should guide the decision to measure DAA.

Abstract
Background: Diabetes mellitus type 1 is the most common endocrine metabolic disorder occurring in childhood and adolescence due to the autoimmune destruction of pancreatic beta cells as a result of various environmental factors interacting with an underlying genetic predisposition. Diabetes is a risk factor for early onset atherosclerosis, and the high mortality rate seen in these patients is partially related to cardiovascular diseases. Objectives: This study was conducted to compare mean platelet volume as a marker of early atherosclerosis with aortic intima-media thickness in children with type 1 diabetes and to identify its correlation with known cardiovascular risk factors. Patients and Methods: The study included 27 patients between age range of 6 and 17 years that were diagnosed with type 1 diabetes and 30 healthy children of the same age range who did not have any chronic disease. In both groups, we used the color Doppler ultrasound to measure children’s aortic intima-media thickness and identify their mean platelet volumes. Results: There was no significant difference between the groups regarding gender distribution, age, High-Density Lipoprotein (HDL) and Low-Density Lipoprotein (LDL) cholesterol levels (P > 0.05). Also no significant difference could be documented between the patient and control groups regarding the aortic intima-media thickness and mean platelet volume (P > 0.05). However, there was a significant correlation between aortic intima-media thickness and mean platelet volume (r = 0.351; P < 0.05). Conclusions: In the present study, there was no evidence of early atherosclerosis in children with type 1 diabetes. However, mean platelet volume having a significant correlation with aortic intima-media thickness may be useful as an early marker of atherosclerosis.

Abstract
OBJECTIVE To estimate the prevalence of diabetes in U.S. youth aged <20 years in 2009 and to estimate the total number of youth with diabetes in the U.S. by age, race/ethnicity, and diabetes type. RESEARCH DESIGN AND METHODS To address one of its primary aims, the SEARCH for Diabetes in Youth Study identified youth aged <20 years on 31 December 2009 with physician-diagnosed diabetes in selected areas of Colorado, Ohio, South Carolina, and Washington, among health plan members of Kaiser Permanente Southern California and among American Indians living on reservations in Arizona and New Mexico. Diabetes was classified as type 1, type 2, or other. Race/ethnicity was by self-report. RESULTS From a population of 3,458,974 youth aged <20 years, 7,695 youth with diabetes were identified (2.22/1,000): 6,668 with type 1 diabetes (1.93/1,000), 837 with type 2 diabetes (0.24/1,000), and 190 (0.05/1,000) with other diabetes types. Prevalence increased with age, was slightly higher in females than males, and was most prevalent in non-Hispanic White and least prevalent in Asian/Pacific Islanders, with Native American and black youth having the highest prevalence of type 2 diabetes. An estimated 191,986 U.S. youth aged <20 years have diabetes; 166,984 type 1 diabetes, 20,262 type 2 diabetes, and 4,740 other types. CONCLUSIONS Diabetes, one of the leading chronic diseases in childhood, affects >190,000 (1 of 433) youth aged <20 years in the U.S., with racial and ethnic disparities seen in diabetes prevalence, overall and by diabetes type.
