Urakami T, Terada H, Mine Y, Aoki M, Suzuki J, Morioka I. Clinical characteristics in children with maturity-onset diabetes of the young detected by urine glucose screening at schools in the Tokyo Metropolitan Area. Clin Pediatr Endocrinol 2024; 33:113-123. [PMID: 38993716 PMCID: PMC11234186 DOI: 10.1297/cpe.2024-0009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/22/2024] [Accepted: 03/27/2024] [Indexed: 07/13/2024] Open
Abstract
This study aimed to examine the clinical characteristics of young children diagnosed with maturity-onset diabetes (MODY) using urine glucose screening at schools. The study participants were 70 non-obese children who were clinically diagnosed with type 2 diabetes through urine glucose screening at schools in Tokyo between 1974 and 2020. Of these children, 55 underwent genetic testing, and 21 were finally diagnosed with MODY: MODY2 in eight, MODY3 in eight, MODY1 in four and MODY5 in one. A family history of diabetes was found in 76.2% of the patients. Fasting plasma glucose levels did not differ between the different MODY subtypes, while patients with MODY 3, 1, and 5 had significantly higher levels of glycosylated hemoglobin and 2-hour glucose in an oral glucose tolerance test than those with MODY2. In contrast, most patients exhibit mild insulin resistance and sustained β-cell function. In the initial treatment, all patients with MODY2 were well controlled with diet and exercise, whereas the majority of those with MODY3, 1, and 5 required pharmacological treatment within one month of diagnosis. In conclusion, urine glucose screening in schools appears to be one of the best opportunities for early detection of the disease and providing appropriate treatment to patients.

Review on the screening of urine glucose for early diagnosis of type 2 diabetes mellitus in school children and adolescents with obesity in Hong Kong. J Pediatr Endocrinol Metab 2024; 37:130-136.

Abstract
OBJECTIVES Obesity and type 2 diabetes mellitus (T2DM) are growing health concerns. Since 2005, Student Health Service (SHS) and Hong Kong Paediatric Society formulated a protocol on urine glucose screening (UGS) for early diagnosis of T2DM in students with obesity in Hong Kong. This study reviews students with T2DM captured by this screening program and compare the data with the Hong Kong Children Diabetes Registry (HKCDR) database, to see if the UGS program facilitates early diagnosis of T2DM. METHODS Students between the ages of 10-18 years old with age- and sex-specific body mass index (BMI) >97th percentile who attended SHS between the school years from 2005/06 to 2017/18 were recruited for UGS. Those tested positive for random urine glucose underwent diagnostic testing for T2DM according to ADA guidelines. Demographic data and investigatory results from UGS and HKCDR within the same time period were compared. RESULTS A total of 216,526 students completed UGS in the said period; 415 (0.19 %) students were tested positive for urine glucose of which 121 students were diagnosed with T2DM. UGS picked up 23 % of the newly diagnosed T2DM cases. When compared to the HKCDR database, students diagnosed via UGS were significantly younger, less obese, and had fewer diabetic related complications. The negative predictive value of UGS is high and can effectively rule out T2DM. CONCLUSIONS Urine glucose screening is an inexpensive and simple test that allows for early diagnosis of T2DM among obese school students. Other methods including POCT HbA1c can be explored to improve program effectiveness.

Identification of High-Risk Groups in Urinalysis: Lessons from the Longitudinal Analysis of Annual Check-Ups. Healthcare (Basel) 2022; 10:healthcare10091704. [PMID: 36141316 PMCID: PMC9498401 DOI: 10.3390/healthcare10091704] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2022] [Revised: 08/30/2022] [Accepted: 09/02/2022] [Indexed: 11/17/2022] Open
Abstract
Background: For effective screening in urinalysis, information on high-risk groups is needed; however, there is a lack of evidence in young adults in particular. The aim of this study was to provide information on urinalysis in young adults and to identify high-risk groups of urinalyses using multi-year data obtained from annual large-scale check-ups. Method: We used annual health check-up data collected from 2011 to 2016 at Kyoto University in Japan. Eligible participants were those aged 18–39 years who underwent annual health check-ups for four consecutive years between 2011 and 2016. We conducted descriptive analyses and calculated the risk ratios (RRs) for urinary abnormalities in the fourth year of urinalysis. Results: In total, 13,640 participants (10,877 men, 79.7%) met the eligibility criteria. The mean prevalence rates of proteinuria, haematuria and glucosuria were 1.61% (men: 1.63%; women: 1.53%), 1.48% (men: 0.53%; women: 5.22%) and 0.46% (men: 0.52%; women: 0.25%), respectively. Participants with urinary abnormalities at least once in the initial 3 years had a higher risk of urinary abnormalities in the fourth year than participants with no abnormal findings in the initial 3 years; the risk ratios (RRs) of proteinuria, haematuria and glucosuria were 3.5 (95% confidence interval (CI) = 3.2–3.7), 12.2 (95% CI = 11.7–12.7) and 42.6 (95% CI = 37.7–48.1), respectively. The RRs of all urinary abnormalities in the fourth year increased as the frequency of urinary abnormalities over the preceding 3 years increased. In haematuria, differences of the RR were observed between men and women. Conclusion: We clarified the prevalence of urinary abnormalities in young adults and high-risk groups of urinary abnormalities. Our findings support the need for multi-year annual urinalysis.

Diabetes Prevalence and Associated Risk Factors among Women in a Rural District of Nepal Using HbA1c as a Diagnostic Tool: A Population-Based Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19127011. [PMID: 35742264 PMCID: PMC9223207 DOI: 10.3390/ijerph19127011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/14/2022] [Revised: 05/30/2022] [Accepted: 06/04/2022] [Indexed: 11/17/2022]
Abstract
Given the scarcity of data on diabetes prevalence and associated risk factors among women in rural Nepal, we aimed to examine this, using glycated hemoglobin (HbA1c) as a diagnostic tool. A cross-sectional survey addressing reproductive health and non-communicable diseases was conducted in 2012–2013 among non-pregnant, married women in Bolde, a rural district of Nepal. HbA1c ≥ 6.5% (48 mmol/mol) was used as diagnostic criterion for diabetes, a cut-off of 7.0% (53 mmol/mol) was used to increase the specificity. HbA1c was measured in 757 women (17–86 years). The prevalence of diabetes and prediabetes was 13.5% and 38.5%, respectively. When using 7.0% as a cut-off, the prevalence of diabetes was 5.8%. Aging, intake of instant noodles and milk and vegetarian food (ns) were associated with increased risk for diabetes. Waist circumference was higher among women with diabetes, although not significant. The women were uneducated (87.6%), and only 12% had heard about diabetes. In conclusion, we observed a higher prevalence of diabetes and prediabetes than anticipated among rural, Nepalese women. The increased risk was mainly attributed to dietary factors. In contrast to most previous studies in Nepal, we used HbA1c as diagnostic criterion.

Epidemiology and phenotypes of diabetes in children and adolescents in non-European-origin populations in or from Western Pacific region. World J Clin Pediatr 2022; 11:173-195. [PMID: 35433305 PMCID: PMC8985498 DOI: 10.5409/wjcp.v11.i2.173] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/30/2021] [Revised: 08/09/2021] [Accepted: 01/05/2022] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Type 1 diabetes (T1D) incidence varies substantially between countries/ territories, with most studies indicating increasing incidence. In Western Pacific region (WPR), reported rates are much lower than European-origin populations. In contrast, there are reports of substantial numbers of young people with type 2 diabetes (T2D). A deeper understanding of T1D and T2D in the WPR may illuminate factors important in pathogenesis of these conditions. Furthermore, with varying resources and funding for diabetes treatment in this region, there is a need to more clearly determine the current burden of disease and also any gaps in knowledge. AIM To compile and summarise published epidemiologic and phenotypic data on childhood diabetes in non-European populations in and from WPR. METHODS Research articles were systematically searched from PubMed (MEDLINE), Embase, Cochrane library, and gray literature. Primary outcome measures were incidence and prevalence, with secondary measures including phenotypic descriptions of diabetes, including diabetes type categorization, presence of diabetic ketoacidosis (DKA) at onset, autoantibody positivity, C-peptide levels, and human leucocyte antigen phenotype. Extracted data were collected using a customized template. Three hundred and thirty relevant records were identified from 16 countries/territories, with analysis conducted on 265 (80.3%) records published from the year 2000. RESULTS T1D incidence ranged from < 1-7.3/100000 individuals/year, rates were highest in emigrant/ mixed populations and lowest in South-East Asia, with most countries/territories (71.4%) having no data since 1999. Incidence was increasing in all six countries/territories with data (annual increases 0.5%-14.2%, highest in China). Peak age-of-onset was 10-14 years, with a female case excess. Rate of DKA at onset varied from 19.3%-70%. Pancreatic autoantibodies at diagnosis were similar to European-origin populations, with glutamic acid decarboxylase-65 autoantibody frequency of 44.1%-64.5%, insulinoma-associated 2 autoantibody 43.5%-70.7%, and zinc transporter-8 autoantibody frequency 54.3% (one study). Fulminant T1D also occurs. T2D was not uncommon, with incidence in Japan and one Chinese study exceeding T1D rates. Monogenic forms also occurred in a number of countries. CONCLUSION T1D is less common, but generally has a classic phenotype. Some countries/ territories have rapidly increasing incidence. T2D is relatively common. Registries and studies are needed to fill many information gaps.

Abstract
BACKGROUND/OBJECTIVES Unregulated inflammatory responses caused by hyperglycemia may induce diabetes complications. Hesperetin, a bioflavonoid, is a glycoside in citrus fruits and is known to have antioxidant and anticarcinogenic properties. However, the effect of inflammation on the diabetic environment has not been reported to date. In this study, we investigated the effect of hesperetin on proinflammatory cytokine secretion and its underlying mechanistic regulation in THP-1 macrophages with co-treatment LPS and hyperglycemic conditions. MATERIALS/METHODS THP-1 cells differentiated by PMA (1 μM) were cultured for 48 h in the presence or absence of hesperetin under normoglycemic (5.5 mM/L glucose) or hyperglycemic (25 mM/L glucose) conditions and then treated with LPS (100 ng/mL) for 6 h before harvesting. Inflammation-related proteins and mRNA levels were evaluated by enzyme-linked immunosorbent assay, western blot, and quantitative polymerase chain reaction analyses. RESULTS Hesperetin (0-100 μM, 48 h) treatment did not affect cell viability. The tumor necrosis factor-α and interleukin-6 levels increased in cells co-treated with LPS under hyperglycemic conditions compared to normoglycemic conditions, and these increases were decreased by hesperetin treatment. The TLR2/4 and MyD88 activity levels increased in cells co-treated with LPS under hyperglycemic conditions compared to normoglycemic conditions; however, hesperetin treatment inhibited the TLR2/4 and MyD88 activity increases. In addition, nuclear factor-κB (NF-κB) and Acetyl-NF-κB levels increased in response to treatment with LPS under hyperglycemic conditions compared to normoglycemic conditions, but those levels were decreased when treated with hesperetin. SIRT3 and SIRT6 expressions were increased by hesperetin treatment. CONCLUSIONS Our results suggest that hesperetin may be a potential agent for suppressing inflammation in diabetes.

Abstract
During the last two decades, there have been several reports of an increasing incidence of type 2 diabetes mellitus (T2DM) in children and adolescents, especially among those belonging to minority ethnic groups. This trend, which parallels the increases in prevalence and degree of pediatric obesity, has caused great concern, even though T2DM remains a relatively rare disease in children. Youth T2DM differs not only from type 1 diabetes in children, from which it is sometimes difficult to differentiate, but also from T2DM in adults, since it appears to be an aggressive disease with rapidly progressive β-cell decline, high treatment failure rate, and accelerated development of complications. Despite the recent research, many aspects of youth T2DM still remain unknown, regarding both its pathophysiology and risk factor contribution, and its optimal management and prevention. Current management approaches include lifestyle changes, such as improved diet and increased physical activity, together with pharmacological interventions, including metformin, insulin, and the recently approved glucagon-like peptide-1 analog liraglutide. What is more important for everyone to realize though, from patients, families and physicians to schools, health services and policy-makers alike, is that T2DM is a largely preventable disease that will be addressed effectively only if its major contributor (i.e., pediatric obesity) is confronted and prevented at every possible stage of life, from conception until adulthood. Therefore, relevant comprehensive, coordinated, and innovative strategies are urgently needed.

Abstract
The prevalence of type 2 diabetes mellitus (T2DM) in children and adolescents is on the rise, and the increase in prevalence of this disorder parallels the modern epidemic of childhood obesity worldwide. T2DM affects primarily post-pubertal adolescents from ethnic/racial minorities and those from socioeconomically disadvantaged backgrounds. Youth with T2DM often have additional cardiovascular risk factors at diagnosis. T2DM in youth is more progressive in comparison to adult onset T2DM and shows lower rates of response to pharmacotherapy and more rapid development of diabetes-related complications. Lifestyle modifications and metformin are recommended as the first-line treatment for youth with T2DM in the absence of significant hyperglycemia. Assessment of pancreatic autoimmunity is recommended in all youth who appear to have T2DM. Pharmacotherapeutic options for youth with T2DM are limited at this time. Liraglutide, a GLP-1 agonist, was recently approved for T2DM in adolescents 10 years of age and older. Several clinical trials are currently underway with youth with T2DM with medications that are approved for T2DM in adults. Bariatric surgery is associated with excellent rates of remission of T2DM in adolescents with severe obesity and should be considered in selected adolescents.

Abstract
OBJECTIVE This study aimed to measure changes of insulin-like growth factor binding protein-1 (IGFBP-1) in patients with type 2 diabetes mellitus (T2D) following gastric bypass surgery. METHODS A total of 10 patients with T2D underwent laparoscopic Roux-en-Y gastric bypass (RYGB) surgery. Patient height, weight, waist circumference, and hip circumference were measured pre- and post-operatively at 6 months after surgery. Serum samples were collected at 6 months after surgery to determine fasting blood glucose, glycosylated Hb, fasting insulin, C-peptide, and 2-h postprandial blood glucose, insulin, and C-peptide. Serum was collected at 3 days and 6 months after surgery and IGFBP-1 level determined using ELISA. Serum samples were also collected from 30 healthy weight subjects and 27 overweight control subjects. RESULTS Body weight, BMI, and waist circumference were significantly improved following RYGB surgery. Blood glucose, fasting blood glucose, 2-h postprandial blood glucose, and HbA1c were also significantly improved. Fasting C-peptide and 2-h postprandial C-peptide were non-significantly reduced. Serum IGFBP-1 significantly increased at 3 days and 6 months after RYGB surgery. Pre-operative serum IGFBP-1 was not significantly different from healthy weight subjects or overweight subjects. CONCLUSION Increased serum level of IGF-binding proteins after RYGB in 6 months is increased post-surgery compared with overweight and healthy weight controls. IGFBP-1 may serve as part of new supplementary criteria for surgical selection and for defining the success of RYGB.

Abstract
BACKGROUND/PURPOSE Type 2 diabetes has become an important cause of diabetes in children. Since most children with type 2 diabetes are asymptomatic, a screening method is needed. However, physicians are required in the screening methods recommended by professional associations. We aimed to develop a simple and efficient screening method for children with diabetes. METHODS A nationwide survey was conducted, which included 2,270,496 seventh-grade students. Students with two abnormal results in sequential urinalyses were given a fasting blood test. Three screening methods were developed. RESULTS Among the screening methods, method C is simple, and can be performed by parents, teachers, or school nurses. It suggests children with two abnormal results in sequential urinalyses and who are overweight or have a family history of diabetes receive blood tests. As a result, 0.10% of boys and 0.16% of girls were recommended to receive blood tests, and 7.0% of boys and 6.7% of girls receiving blood tests were diagnosed diabetes. On average, 15,002 boys and 9056 girls had to be screened to find one child with diabetes. The cost per 1000 children by method C was 2466.84 US dollars. CONCLUSION Urinalysis screening followed by evaluation of risk factors is a simple and efficient way to identify children with diabetes in schools.

Abstract
By 2017 estimates, diabetes mellitus affects 425 million people globally; approximately 90-95% of these have type 2 diabetes. This narrative review highlights two domains of sex differences related to the burden of type 2 diabetes across the life span: sex differences in the prevalence and incidence of type 2 diabetes, and sex differences in the cardiovascular burden conferred by type 2 diabetes. In the presence of type 2 diabetes, the difference in the absolute rates of cardiovascular disease (CVD) between men and women lessens, albeit remaining higher in men. Large-scale observational studies suggest that type 2 diabetes confers 25-50% greater excess risk of incident CVD in women compared with men. Physiological and behavioural mechanisms that may underpin both the observed sex differences in the prevalence of type 2 diabetes and the associated cardiovascular burden are discussed in this review. Gender differences in social behavioural norms and disparities in provider-level treatment patterns are also highlighted, but not described in detail. We conclude by discussing research gaps in this area that are worthy of further investigation.

Abstract
AIMS Previous studies indicated that urinary glucose (UG) had a limited efficacy in diabetes screening. This study was designed to have a re-evaluation of its efficacy, taking into consideration the collection method of urine and the measurement approach for UG among Chinese adults. METHODS This cross-sectional study enrolled a total of 7689 participants without known diabetes, who were fasted and asked to empty bladders before a 75 g glucose loading. Urine was collected 2 h post glucose loading, and UG was measured using quantitative and qualitative approaches. The efficacy of UG in detecting diabetes was assessed by the receiver operating characteristic (ROC) curve. RESULTS The area under the ROC curve was 0.89 for quantitative UG and 0.87 for qualitative UG. Quantitative UG was positively correlated with fasting plasma glucose (FPG) and 2 h plasma glucose (2 h PG) (r = 0.55 and 0.56, respectively, both P < 0.001). Quantitative UG displayed a sensitivity of 82.9% and a specificity of 84.7% in detecting diabetes at the corresponding optimal cutoff of 130 mg. Qualitative UG exhibited a sensitivity of 80.2% and a specificity of 85.6% at the optimal cutoff of glycosuria + 1. In addition, the sensitivity of both quantitative and qualitative UG was significantly higher than that of HbA1c (≥ 6.5%) (P < 0.001) and had a comparable sensitivity to 2 h PG (≥ 11.1 mmol/L) (P = 0.493). CONCLUSIONS UG, either quantitatively or qualitatively measured at 2 h post glucose loading, was effective in diabetes screening. This indicates that UG is a feasible approach for diabetes screening.

The Characteristics Of Abdominal Fat Distribution In Japanese Adolescents With Type 2 Diabetes Mellitus. Diabetes Metab Syndr Obes 2019; 12:2281-2288. [PMID: 31807041 PMCID: PMC6830372 DOI: 10.2147/dmso.s223049] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/13/2019] [Accepted: 10/24/2019] [Indexed: 11/26/2022] Open
Abstract
PURPOSE The aim was to investigate the characteristics of abdominal fat distribution in Japanese adolescents with type 2 diabetes mellitus. PATIENTS AND METHODS Eighty-six Japanese adolescents with simple obesity or type 2 diabetes mellitus treated between 2002 and 2018 were included. The subjects were classified into the simple obesity group (SO group, n=38) and type 2 diabetes mellitus group (DM group, n=23) by matching average age and gender ratio. The metabolic parameters VFA, SFA, and V/S ratio were compared between the 2 groups. Multivariate logistic regression analysis was performed to identify clinical factors associated with type 2 diabetes mellitus. Linear regression analysis was performed between hemoglobin A1c (HbA1c) and visceral fat area (VFA), subcutaneous fat area (SFA), or VFA-to-SFA ratio (V/S ratio) among all enrolled subjects. Finally, correlation analyses were performed to determine the relationships between VFA, SFA, and V/S ratio and metabolic parameters of the DM group. For the metabolic parameters, serum lipids, alanine aminotransferase (ALT), and HbA1c were measured without fasting. The VFA and SFA at umbilical level were investigated using computed tomography. RESULTS VFA and V/S ratio in DM group were higher than those in SO group (p=0.04 and p<0.01, respectively). SFA in DM group was lower than that in SO group (p<0.01). VFA and SFA, and non-high density lipoprotein (HDL) cholesterol were identified as being independently associated with type 2 diabetes mellitus (odds ratio, 1.05, 0.98, and 1.04, respectively, p<0.05). HbA1c was correlated with VFA and V/S ratio (p<0.01). In DM group, VFA and SFA were positively correlated with systolic blood pressure (p<0.01), ALT (p<0.05), total cholesterol (p<0.05), and non-HDL cholesterol (p<0.01); however, V/S ratio was not correlated. CONCLUSION Abdominal fat distribution in Japanese adolescents with type 2 diabetes mellitus was different from those with simple obesity and might associate with glucose and lipid metabolism.

Abstract
OBJECTIVE To analyze changes in the annual incidence of school students with type 2 diabetes detected by urine glucose screening at schools in the Tokyo Metropolitan Area during 1975-2015. METHODS Trend in temporal changes in the annual incidence rate were analyzed using a joinpoint regression model and the joinpoints. Annual percent change (APC) was calculated for each segmented line regression. Average annual percent change (AAPC) was also calculated for the whole period analyzed. RESULTS In total, 301 students, including 64 primary school students and 237 junior high school students, were diagnosed with type 2 diabetes. The overall incidence of type 2 diabetes (per 100 000/year) during the entire study period was 2.58 in all students, 0.80 in primary school students, and 6.41 in junior high school students. AAPC during the entire study period was estimated at -1.5 (not significant), and the incidence significantly increased during 1975-1982 (APC = 17.49, P < 0.05), but tended to decrease during 1982-2015 (APC = -1.01). In primary school students, the incidence significantly increased during1975-2010 (APC = 3.30, P < 0.05), and tended to decrease during 2010-2015 (APC = -29.61). In junior high school students, the incidence did not significantly change during the entire study period (APC = 0.06). CONCLUSIONS We found increasing trend in the overall incidence of school students with type 2 diabetes during 1975-1982, but a decreased tendency in recent years. This could be due to changes observed during the same time period in the primary school students. Lifestyle changes might contribute to improved incidence of childhood type 2 diabetes.

Abstract
It is well known that the incidence of youth-onset type 2 diabetes is increasing worldwide. On the other hand, most studies have shown that the majority of youth-onset type 2 diabetes occurs in obese individuals, generally with a body mass index (BMI) greater than the 90th or 95th centile for sex- and age-matched children and adolescents. However, we identified some Japanese children with nonobese type 2 diabetes and BMI less than 90th centile by a urine glucose screening program at schools in the Tokyo Metropolitan Area. According to the results obtained from the screening, clinical characteristics of patients with nonobese type 2 diabetes seemed to be different from those in obese type 2 diabetes. Nonobese patients tended to show lower insulin secretion abilities and milder, but evident, insulin resistance from the time of diagnosis. Female, low birth weight (small for gestational age), and genetic background, not related to β-cell-associated autoimmunity, may play a role in development of nonobese type 2 diabetes. In addition, nonobese patients tend to progress earlier to pharmacological treatment including oral hypoglycemic drugs and insulin. Further studies are needed to confirm to these findings and clarify the pathophysiology of children with nonobese type 2 diabetes.

Abstract
Objective To evaluate the safety and effectiveness of metformin monotherapy for 52 weeks, including 24 weeks of treatment and a 28-week extension period for evaluation of long-term safety, in 37 Japanese pediatric patients with type 2 diabetes mellitus. Research design and methods This study design was an open-label, non-randomized, multicenter trial. The primary effectiveness endpoint was the changes from baseline to the final visit at 24 weeks in HbA1c. The secondary endpoints were the rate for achieving the treatment goal, and the changes in glycated albumin, fasting blood glucose, fasting insulin, HOMA-IR, and fasting serum lipids. Metformin was administrated at the dose of 500 mg/day up to a maximum of 2000 mg/day taken in two or three divided doses. Results The mean change of HbA1c at the final visit at 24 weeks for 20 metformin-naïve patients (Group A) was - 0.66 ± 0.95% and that of 17 already-on metformin patients (Group B) was - 0.98 ± 1.62%. These figures proved the effectiveness of metformin as defined before the study. Secondary effectiveness endpoints were also improved. The improvement of blood glucose, fasting insulin and serum lipid levels proved the effectiveness of metformin without increasing body weight. Adverse effects such as nausea and diarrhea were observed in 35 of the 37 subjects and drug-related adverse events were observed in 19 patients. However, these events were not serious and did not increase with long-term treatment. Conclusions Metformin is safe and effective for Japanese pediatric patients with T2DM.

Abstract
PURPOSE OF REVIEW To provide an update on knowledge the role of genetics in youth-onset type 2 diabetes (T2D). RECENT FINDINGS The prevalence in youth of T2D, once thought to be exclusively a disease of adults, has increased by over 35% since 2001. Youth with T2D tend to have higher rates of complications, more aggressive disease, with more rapid loss of beta-cell function and a less favorable response to treatment than adults. Obesity is the most important risk factor for T2D, and the rise in childhood overweight and obesity appears responsible for the dramatic increase in T2D in youth. However, some obese children do not develop T2D, consistent with genetic differences in susceptibility to the disease in the setting of obesity and insulin resistance, currently far less well characterized in youth than in adults. Recent studies have begun to show associations of several established adult T2D genetic risk variants with youth-onset T2D and related glycemic quantitative traits, including the strongest known cross-population T2D genetic contributor TCF7L2. Maturity-onset diabetes of the young (MODY), a diabetes subtype distinct from type 1 diabetes (T1D) and T2D, is now known to result from a highly penetrant gene mutation in one of several genes. MODY has been shown to account for or contribute to at least 4.5% of clinically diagnosed T2D, even among those who are overweight or obese, impacting treatment decisions. The recently formed ProDiGY (Progress in Diabetes Genetics in Youth) Consortium is using genome-wide association studies and whole exome sequencing to understand the genetic architecture of T2D in youth, including how it differs from that of adults. The limited amount of research conducted to date on the genetics of youth-onset T2D, which tends to be a more aggressive disease than adult T2D, suggests some overlap with genes involved in adult T2D and a sizeable influence of highly penetrant monogenic diabetes variants. The ProDiGY Consortium is expected to provide a more comprehensive understanding of youth T2D genetics.

Abstract
Objective of this study was to analyze prevalence changes in type 2 diabetes (T2D) among children and adolescents over the last 10 years. We performed a cross-sectional survey in Baden-Württemberg (BW), Germany, by using a written questionnaire and comparing these results with T2D prevalence data from the same area retrieved in 2004/2005. In 2016, 50 patients with T2D under 20 years of age were registered in BW, Germany, which corresponds to a prevalence rate of 2.42 per 100 000 (95% confidence interval [CI]: 1.75-3.09). The prevalence rate found in the same geographic area 10 years prior was 2.30 per 100 000 (95% CI: 1.70-2.90). Overall, 70% of T2D patients of this age group were treated by adult diabetologists. Concisely the prevalence of T2D in children and adolescents is still low in South Germany, remaining practically unchanged over the past decade.

Abstract
The number of children with Metabolic Syndrome (MetS) has recently been increasing in Japan. Few studies have investigated the relationship between MetS and oral health. The aim of this study was to investigate the association between MetS, lifestyle, and oral health status in school children. Our goal is to utilize these results in health education aimed at preventing the onset of MetS in school children and adults. A total of 689 Japanese children (365 boys and 324 girls) aged between 10 and 13 years were examined and waist circumference (WC), ratio of WC to height, blood pressure, fasting blood sugar (FBS), high density lipoprotein-cholesterol, and triglyceride values determined together with oral health status, including dental caries experience (DMFT). The results revealed that 6.5% of the children fell under the health board recognized "MetS or high risk of MetS" (MetS/HR) classification. A total of 140 (20%) children had a high Streptococcus mutans count. The mean WC, FBS, and DMFT values were significantly greater in children with a high salivary S. mutans count (p<0.05). Multiple logistic regression analysis revealed a statistically significance association between MetS/HR, non-breakfast eaters (odds ratio (OR): 2.70), no regular exercise (OR: 2.60), and a high salivary S. mutans count (≥10(5) CFU/ml; OR: 2.18; p<0.05). The present results indicate that lifestyle and salivary S. mutans count could be useful in screening children for MetS/HR. These variables may be useful in targeting interventions aimed at preventing MetS in school children.

Abstract
PURPOSE OF REVIEW To review clinical characteristics of pediatric type 2 diabetes in Japan. RECENT FINDINGS It is well recognized that Asian populations, particularly the Japanese, have a higher incidence of childhood type 2 diabetes. Of note, most Asian populations show a higher incidence of pediatric type 2 diabetes than that of type 1 diabetes. However, a current report in the USA demonstrated a dramatic increase in the incidence of young people with type 2 diabetes in recent years. The USA could have a much higher incidence of type 2 diabetes than Japan, possibly due to environmental and behavioral factors. The clinical features of Japanese young people with type 2 diabetes might have some differences from type 2 diabetes in other pediatric populations. Japanese children with type 2 diabetes are likely to be thinner than Caucasian children. Approximately 10-15% Japanese patients with type 2 diabetes exhibit normal weight with milder insulin resistance and substantial insulin secretion failure. Autoimmunity is not associated with the etiology of type 2 diabetes. Some genetic background and environmental factors, different from those in Caucasians, could play a role in the development of type 2 diabetes in Japanese children. Considering these characteristics, we must consider adequate therapy and management for young people with type 2 diabetes.

Abstract
The principal treatment for children and adolescents with type 2 diabetes is dietary and
exercise management. However, the blood glucose levels of some patients receiving this
treatment fail to improve; thus, pharmacological treatment is eventually required. The
pathophysiology of type 2 diabetes in pediatric patients appears to be similar to that in
adults; thus, the range of antidiabetic drugs used in adults is likely to be effective in
pediatric patients as well. However, in the majority of countries, including Japan, only
metformin, glimepiride, and insulin have been approved for use in pediatric patients.
Indeed, the evidence for the usefulness of antidiabetic drugs other than metformin and
insulin in children and adolescents is limited at this time. Therefore, the efficacy and
safety of various antidiabetic drugs, including DPP-4 inhibitors, GLP-1 receptor agonists,
and SGLT2 inhibitors, which are used in adult patients, should be evaluated in the
pediatric population in a large number of centers worldwide. In addition, it is critical
that researchers and clinicians establish treatment guidelines for children and
adolescents with type 2 diabetes in all racial groups worldwide.

Abstract
BACKGROUND We conducted an annual urine glucose screening program at schools, and diagnosed schoolchildren with diabetes at an early stage of the disease. We also identified some cases of renal glucosuria (RG), based on positive urine glucose with normal glucose tolerance. METHODS During 2000-2015, 3 309 631 schoolchildren participated in the screening program. The positive rate for glucosuria in the first test was approximately 0.1%, whereas on repeat urine test it was approximately 0.05%. In total 350 schoolchildren were positive for glucosuria on detailed examination. Oral glucose tolerance test (OGTT) was also used to evaluate glucose intolerance. RESULTS One hundred and two schoolchildren (29.7%) were diagnosed with diabetes, whereas RG was identified in 246 (70.3%) with normal glucose metabolism. In regard to the characteristics of RG, the percentage of boys was 50.3%, and the mean age at diagnosis was 11.2 ± 2.4 years. Twenty-eight children (11.4%) were overweight (body mass index standard deviation score [BMI-SDS] > +2.0 SD), whereas five (2.0%) were underweight (BMI-SDS < -2.0 SD). First-degree family history was suspected in 176 cases (71.5%). All RG subjects had normal glucose tolerance in the absence of insulin resistance and decreased insulin secretion (homeostasis model assessment for β-cell function, 78.8 ± 59.5%) on OGTT. CONCLUSIONS RG is not rare in Japanese schoolchildren with glucosuria. This disorder seems to have a strong genetic background, and to involve less growth retardation and weight loss than expected despite continuous excretion of glucose in urine.

Abstract
This study aimed to investigate the prevalence of glucosuria and the characteristics of diabetes in schoolchildren as detected by a school urine glucose screening program implemented from 2010 to 2013 in the Jeonbuk province area of Korea. A total of 110 children without known diabetes were analyzed. They were checked with an oral glucose tolerance test (OGTT) with other laboratory tests and their clinical data were collected. A total of 707,238 schoolchildren from a school population of 1,064,999 were screened for glucosuria. In total, over a 4-year period, 545 schoolchildren (0.077%) were positive for glucosuria on the second urine test. The prevalence of glucosuria was more common among middle and high schoolchildren than among elementary schoolchildren. Among 110 students who completed the OGTT to confirm diabetes, 40 were diagnosed with diabetes mellitus (DM); 39 children, type 2 diabetes mellitus (T2DM) and 1 child, slowly progressive insulin dependent diabetes mellitus (SPIDDM). The mean annual incidence of diabetes was 5.6 per 100,000 schoolchildren and adolescents. The subjects with diabetes diagnosed through the urine screening test showed minimal or no symptoms of diabetes. The students with diabetes were more likely to be woman and obese, and they have a higher body mass index, higher cholesterol, triglyceride, insulin, C-peptide, and fasting glucosuria values than the students with normal glucose tolerance. We identified 40 new cases of diabetes in the Korean schoolchildren with asymptomatic glucosuria on urine glucose screening. This finding shows that school urine glucose screening is a feasible and simple method for early detection of asymptomatic T2DM.

Abstract
Abstract
Numerous Asian countries have a high prevalence of metabolic syndrome, also associated with cardiovascular disease and diabetes mellitus. Healthcare expenditure varies among Asian countries, and is influenced by poverty factor and large populations. The effect of metabolic syndrome on nutritional management in Asia demonstrates the essential for clinicians to equalize the needs for higher standards of dietetics practice; as they execute optimal care processes with the aim of improving outcomes, alongside setting of workforce limitations, inadequate expertise in metabolic syndrome nutrition practice, as well as ethnic diversity among Asians. This paper presents some aspects of dietetics practice and the possibility that an alteration in practice is mandatory if dietitians are to play an active role in preventing or decelerating the evolution of the metabolic syndrome.

Abstract
BACKGROUND The incidence of type 2 diabetes mellitus (T2DM) has been increasing globally over the past two decades in children and adolescents. There are currently a dearth of comprehensive population-based estimates of T2DM incidence and time trends in Chinese youth. METHODS A population-based diabetes registry system in 30 representative districts in Zhejiang has been established for diabetes surveillance. All newly cases diagnosed by physicians in local hospitals and wards were registered using the registry system through web services and direct network report. The data were primarily abstracted from medical records in hospitals and wards. Annual incidence rates and their 95% confidence intervals (CIs) by age groups and sex were calculated per 100 000 person-years. Poisson regression models were applied to assess the effects of diagnosis year, age groups, sex and residence area on T2DM incidence and to examine the average annual percentage change in incidence. RESULTS There were 392 newly diagnosed cases of T2DM (210 boys and 182 girls) over the study period. The mean annual age-standardized incidence was 1.96/100 000 person-years (95% CIs: 1.85-2.08). No statistically significant difference in incidence was found between boys and girls. However, the risk for T2DM was 1.49 times higher in urban area than in rural area. Besides, the mean annual incidence in youth increased with age. The age-standardized incidence was about 5 times higher in 2013 than in 2007. Steep rising incidence was observed, with an average annual increase of 26.6% in youth aged 10-19 years. CONCLUSIONS The incidence of T2DM in children and adolescents was low in Zhejiang relative to other countries, whereas it increased markedly over the study period. Preventive strategies for T2DM are necessary in pediatric population.

Abstract
CONTEXT Food insecurity is a preventable health threat and may precipitate central obesity and metabolic syndrome in children and adolescents in the United States. OBJECTIVE To examine (1) health by household food security status; and (2) differences and prevalence of central obesity among persons aged 12 to 18 years in the United States. METHODS The National Health and Nutrition Examination Survey was administered to a cross-sectional sample of persons aged 12 to 18 years in 1999 to 2006. Controlling for age, race/ethnicity, and sex differences in mean obesity and chronic disease factors across levels of food insecurity (analysis of covariance [Bonferroni post hoc] and ORs [logistic regression analyses]) were examined, as were differences in the rates of risk factors (χ(2) statistics). RESULTS A total of 7435 participants were analyzed. Those from marginally food secure (n=751) and low-food secure (n=1206) (population size estimate, 26,714,182) households were significantly more likely than their high-food secure counterparts (n=4831) to be overweight (P=.036) (OR, 1.44), and those from marginally food secure households were 1.3-times more likely to be obese (P=.036). Nearly 25% of respondents from marginally food secure, low-food secure, and very low-food secure (n=647) households reported central obesity (P=.002), which was 1.4 to 1.5 times more likely than those from high-food secure households. Participants from high-food secure households had significantly higher mean high-density lipoprotein values (P=.019). Risk factors indicative of metabolic syndrome were present in 3.1%. CONCLUSION Household food insecurity was associated with an increased likelihood of being overweight and having central obesity. Limitations included the use of cross-sectional data and some self-reported data and the inability to control for all moderating variables in obesity and overall health status.

Abstract
Diabetes mellitus is one of the most common endocrine disorders in children. Earlier, diabetes in children was almost exclusively type 1 diabetes. Recently, the scenario has changed and increasing numbers of children and adolescent T2DM are being diagnosed. As the epidemic of T2DM shifts to children and adolescents, there is an increased risk of development of micro and macrovascular complications. This could potentially affect the economy of the nation apart from posing a large burden to the individual and his or her family. Prevention and treatment are especially important, given the fact that onset at an early age increases the risk of developing micro and macrovascular complications due to increased duration of exposure to hyperglycemia and other metabolic abnormalities. Diagnosing children and adolescents with T2DM early and instituting good control of all risk factors could yield good results in the prevention of long term complications of diabetes. This review focuses on the prevalence of complications of diabetes among children and adolescents with T2DM.

Abstract
Diabetes severely impairs male reproduction. The present study assessed the effects and mechanisms of action of advanced glycation end products (AGEs), which play an important role in the development of diabetes complications, on testosterone secretion by rat Leydig cells. Primary rat Leydig cells were cultured and treated with AGEs (25, 50, 100 and 200 µg/ml). Testosterone production induced by human chorionic gonadotropin (hCG) was determined by ELISA. The mRNA and protein expression levels of steroidogenic acute regulatory protein (StAR), cholesterol side-chain cleavage enzyme (P450scc) and 3β-hydroxysteroid dehydrogenase (3β-HSD), which are involved in testosterone biosynthesis, were measured by reverse transcription-quantitative PCR and western blot analyssi, respectively. Reactive oxygen species (ROS) production in Leydig cells was measured using the dichlorofluorescein diacetate (DCFH-DA) probe. The expression levels of endoplasmic reticulum stress-related proteins [C/EBP homologous protein (CHOP) and glucose-regulated protein 78 (GRP78)] in the Leydig cells were measured by western blot analysis. We found that the AGEs markedly suppressed testosterone production by rat Leydig cells which was induced by hCG in a concentration-dependent manner compared with the control (P<0.01). The mRNA and protein expression levels of StAR, 3β-HSD and P450scc were downregulated by the AGEs in a dose-dependent manner compared with the control (P<0.01). The antioxidant agent, N-acetyl‑L‑cysteine (NAC), and the endoplasmic reticulum stress inhibitor, tauroursodeoxycholic acid (TUDCA), reversed the inhibitory effects of AGEs. In addition, the content of ROS in Leydig cells treated with AGEs increased significantly. The expression levels of CHOP and GRP78 were markedly upregulated by the AGEs in the Leydig cells. From these findings, it can be concluded that AGEs inhibit testosterone production by rat Leydig cells by inducing oxidative stress and endoplasmic reticulum stress.

Abstract
We treated 80 obese and 28 nonobese children diagnosed as having type 2 diabetes mellitus (T2DM). Among these patients, 26 obese and 23 nonobese children were assigned to pharmacologic therapies during the course of diabetes. Pharmacologic therapies were started if the HbA1c (NGSP) value exceeded 7.0% despite dietary and exercise management. For the 26 obese patients, metformin alone or in combination with an additional medication was frequently used. Only 2 patients independently received sulfonylureas (SUs) in the form of glimepiride. In addition, 9 patients were treated with basal insulin supported with oral hypoglycemic drugs (OHDs) or biphasic premix insulin. On the other hand, the 23 nonobese patients were frequently treated with insulin alone or in combination with an additional medication followed by SUs. The nonobese patients tended to require pharmacologic therapies, in particular insulin, at an earlier stage of diabetes as compared with the obese patients. New antidiabetic drugs, DPP-4 inhibitors and GLP-1 receptor agonists, seemed to exert positive effects on glycemic control without occurrence of hypoglycemic episodes in some patients regardless of the type of diabetes. These results suggest that pharmacologic treatment strategies in childhood T2DM should be tailored to individual patient characteristics.

Abstract
AIMS/HYPOTHESIS This study aimed to systematically review what has been reported on the incidence and prevalence of type 2 diabetes in children and adolescents, to scrutinise the methodological issues observed in the included studies and to prepare recommendations for future research and surveillances. METHODS PubMed, the Cochrane Database of Systematic Reviews, Scopus, EMBASE and Web of Science were searched from inception to February 2013. Population-based studies on incidence and prevalence of type 2 diabetes in children and adolescents were summarised and methodologically evaluated. Owing to substantial methodological heterogeneity and considerable differences in study populations a quantitative meta-analysis was not performed. RESULTS Among 145 potentially relevant studies, 37 population-based studies met the inclusion criteria. Variations in the incidence and prevalence rates of type 2 diabetes in children and adolescents were mainly related to age of the study population, calendar time, geographical regions and ethnicity, resulting in a range of 0-330 per 100,000 person-years for incidence rates, and 0-5,300 per 100,000 population for prevalence rates. Furthermore, a substantial variation in the methodological characteristics was observed for response rates (60-96%), ascertainment rates (53-99%), diagnostic tests and criteria used to diagnose type 2 diabetes. CONCLUSIONS/INTERPRETATION Worldwide incidence and prevalence of type 2 diabetes in children and adolescents vary substantially among countries, age categories and ethnic groups and this can be explained by variations in population characteristics and methodological dissimilarities between studies.

Abstract
Aims/Introduction To investigate trends over the past 20 years for the prevalence of obesity and glycemic control in association with a patient's first hospital visit for type 2 diabetes mellitus. Materials and Methods This was a historical, cross‐sectional, time‐series, single‐center study carried out at Marunouchi Hospital. Data from type 2 diabetic patients who were never treated until their first hospital visit were analyzed for the following periods: 1986–1987 (group A, n = 453), 1996–1997 (group B, n = 547) and 2006–2008 (group C, n = 443). Data on each patient's body mass index (BMI), age, untreated duration and glycated hemoglobin levels were also collected. Results Obesity in younger patients (below age 40 years and ages 40–49 years in group C) with poor glycemic control increased over time. Patients with a BMI of <21.0 kg/m2 or ≥23.0 kg/m2 showed worse glycemic control than those with a BMI of 21.0–23.0 kg/m2 in group C. Younger patients had worse glycemic control and shorter untreated durations in group C. A BMI ≥23.0 kg/m2 was an independent risk factor for glycated hemoglobin levels ≥8.4% in group C, even after correction for sex, age, untreated duration and symptoms. Conclusions In recent years, glycemic control has worsened in young, obese patients in urban Japan. Obesity is rapidly increasing in younger patients, and patients with a BMI ≥23.0 kg/m2 might be candidates for diabetes screening. This trial was registered with the University Medical Information Network Clinical Trials Registry (no. UMIN000005725).

Abstract
There is an epidemic of diabetes in Asia. Type 2 diabetes develops in East Asian patients at a lower mean body mass index (BMI) compared with those of European descent. At any given BMI, East Asians have a greater amount of body fat and a tendency to visceral adiposity. In Asian patients, diabetes develops at a younger age and is characterized by early β cell dysfunction in the setting of insulin resistance, with many requiring early insulin treatment. The increasing proportion of young-onset and childhood type 2 diabetes is posing a particular threat, with these patients being at increased risk of developing diabetic complications. East Asian patients with type 2 diabetes have a higher risk of developing renal complications than Europeans and, with regard to cardiovascular complications, a predisposition for developing strokes. In addition to cardiovascular-renal disease, cancer is emerging as the other main cause of mortality. While more research is needed to explain these interethnic differences, urgent and concerted actions are needed to raise awareness, facilitate early diagnosis, and encourage preventive strategies to combat these growing disease burdens.

Abstract
AIMS We examined the clinical characteristics of non-obese Japanese children with type 2 diabetes mellitus (T2DM) not associated with β-cell autoimmunity. METHODS Of 218 children who were diagnosed as having T2DM by a school urine glucose screening program in Tokyo, 24 were identified as being non-obese and were enrolled in this study. None of the children had any evidence of β-cell autoimmunity or genetic disorders. RESULTS The mean ages at diagnosis and at the study were 12.5 ± 1.7 and 22.4 ± 5.7 years, respectively. Females were predominant (M/F ratio: 4/20). Family history of T2DM, mostly of the non-obese type, was present in 62.5% of the cases. In regard to the birth weight, 20.8% had a history of low birth weight, and 8.3% were large for gestational age. The mean fasting insulin level, HOMA-R, HOMA-β, and an insulinogenic index on the OGTT at the time of diagnosis were 11.8 ± 7.8 μU/ml, 5.4 ± 3.8, 96.1 ± 55.0 and 0.16 ± 0.14, respectively. Most patients were treated by either oral hypoglycemic drug (45.8%) or insulin (50.0%) therapy at the study, with the mean interval to the start of pharmacological treatment of 3.1 ± 2.3 years. CONCLUSIONS Non-obese children with T2DM seemed to show lower insulin secretory capacities with mild, but evident, insulin resistance even from the time of diagnosis, and also earlier requirement of pharmacological therapies during the clinical course. Some genetic factors not associated with autoimmunity may play a role in the etiology of T2DM in non-obese children.

Abstract
BACKGROUND Insulin resistance at diagnosis was investigated in Japanese children with type 2 diabetes mellitus (T2DM). METHODS A total of 160 children with T2DM were divided into groups on the basis of percent overweight at time of diagnosis: group A (n = 28), <20%; group B (n = 55), 20-39%; group C (n = 37), 40-59%; group D (n = 40), ≥ 60%. Indicators of insulin resistance at diagnosis were compared among the four patient groups, and also between the children with T2DM and the 201 age-matched normal Japanese children. RESULTS There were no significant differences in plasma glucose (PG) levels among the four patient groups. The mean concentration of fasting plasma immunoreactive insulin (IRI) was significantly higher in group D than in groups A and B (39.2 µU/mL vs 16.2 µU/mL and 24.1 µU/mL, P < 0.05, respectively). The mean homeostasis model assessment (HOMA-R) was significantly higher in group D than in all the other three groups (17.6 vs 7.8, 10.8 and 12.7, P < 0.05, respectively). The indicators HOMA-R and fasting IRI were significantly higher in each diabetes group, even in non-obese group A, than in normal children (P < 0.01, respectively). CONCLUSIONS Japanese children with T2DM had insulin resistance at diagnosis regardless of percent overweight, and the degree of insulin resistance gradually increased with rise in percent overweight.

Abstract
Increased adiposity and unhealthy lifestyle augment the risk for type 2 diabetes in children with familial predisposition. Insulin resistance (IR) is an excellent clinical marker for identifying children at high risk for type 2 diabetes. This study was conducted to investigate parental, physiological, behavioral and socio-economic factors related to IR in Korean children. This study is a cross-sectional study using data from 111 children aged 7 years and their parents. Homeostasis model assessment of insulin resistance (HOMA-IR) was calculated using fasting glucose and insulin level as a marker of IR. All children’s adiposity indices (r = 0.309–0.318, all P-value = 0.001) and maternal levels of fasting insulin (r = 0.285, P-value = 0.003) and HOMA-IR (r = 0.290, P-value = 0.002) were positively correlated with children’s HOMA-IR level. There was no statistical difference of children’s HOMA-IR level according to children’s lifestyle habits and socioeconomic status of families. An increase of 1 percentage point in body fat was related to 2.7% increase in children’s HOMA-IR (P-value < 0.001) and an increase of 1% of maternal level of HOMA-IR was related to 0.2% increase in children’s HOMA-IR (P-value = 0.002). This study shows that children’s adiposity and maternal IR are positively associated with children’s IR.

Abstract
BACKGROUND In Asians, mutations in the known maturity-onset diabetes of the young (MODY) genes have been identified in only <15% of patients. These results were obtained mostly through studies on adult patients. OBJECTIVE To investigate the molecular basis of Japanese patients with pediatric-onset MODY-type diabetes. SUBJECTS Eighty Japanese patients with pediatric-onset MODY-type diabetes. METHODS Mitochondrial 3243A>G mutation was first tested by the polymerase chain reaction restriction fragment length polymorphism analysis for maternally inherited families. Then, all coding exons and exon-intron boundaries of the HNF1A, HNF1B, GCK, and HNF4A genes were amplified from genomic DNA and directly sequenced. Multiplex ligation-dependent probe amplification analysis was also performed to detect whole-exon deletions. RESULTS After excluding one patient with a mitochondrial 3243A>G, mutations were identified in 38 (48.1%) patients; 18 had GCK mutations, 11 had HNF1A mutations, 3 had HNF4A mutations, and 6 had HNF1B mutations. In patients aged <8 yr, mutations were detected mostly in GCK at a higher frequency (63.6%). In patients >9 yr of age, mutations were identified less frequently (45.1%), with HNF1A mutations being the most frequent. A large fraction of mutation-negative patients showed elevated homeostasis model assessment (HOMA) insulin-resistance and normal HOMA-β indices. Most of the HNF1B mutations were large deletions, and, interestingly, renal cysts were undetectable in two patients with whole-gene deletion of HNF1B. CONCLUSION In Japanese patients with pediatric-onset MODY-type diabetes, mutations in known genes were identified at a much higher frequency than previously reported for adult Asians. A fraction of mutation-negative patients presented with insulin-resistance and normal insulin-secretory capacities resembling early-onset type 2 diabetes.

Abstract
We examined the correlation between plasma glucose (PG) and hemoglobin A1c (HbA1c) to evaluate the usefulness and limitations of applying the new diagnostic criteria for diabetes to Japanese pediatric patients. Data were collected from 298 school children who took an oral glucose tolerance test (OGTT) at a school-based urinary glucose screening program in the Tokyo Metropolitan Area between 1988 and 2009. Mean (SD) age of the children was 11.9 (2.5) years. Male-to-female ratio was 1:1.1. Children were diagnosed with renal glucosuria (n=146), diabetes mellitus (n=133), or the Japan Diabetes Society (JDS) "borderline type" (n=19). Median (range) values of fasting plasma glucose (FPG), 2-h plasma glucose in an OGTT (OGTT-2h), and HbA1c were 101 (76-378) mg/dL, 146.5 (57-563) mg/dL, and 6.05 (4.7-14.1) %. The correlation between PG and HbA1c was analyzed using least squares regression, and HbA1c was found to highly correlate with PG. From estimated regression equations, mean values of FPG and OGTT-2h corresponding to an HbA1c of 6.5% were calculated to be 111.4 mg/dL and 170.4 mg/dL. The mean values of HbA1c corresponding to an FPG of 126 mg/dL and OGTT-2h of 200 mg/dL were calculated to be 7.5% and 7.8%. The mean values of PG corresponding to HbA1c of 6.5% were lower than found in adults as analyzed by JDS. The mean values of HbA1c corresponding to diabetic type PG were higher than found in adults.

Abstract
AIM To understand the etiology of childhood-onset diabetes, we examined genetic risk markers, autoantibodies, and β-cell function in a mixed race group of young patients. METHODS One hundred and forty-five patients aged 0-17 at diagnosis (54% African American, 22% Caucasian, 16% Latino, 8% mixed-other) were studied at mean duration 6.9 ± 5.7 (range 0.1-28.5) yr, including human leukocyte antigen (HLA)-DQA1-DQB1 genotyping, stimulated C peptide (CP), glutamic acid decarboxylase, and insulinoma-associated antigen 2 antibodies (ABs). Based on no residual β-cell function (CP-) and islet autoantibodies (AB+), 111 patients were classified with type 1 diabetes mellitus (T1DM), 22 were CP+ and AB- and thus considered to have type 2 diabetes mellitus (T2DM), and 12 patients had features of both T1DM and T2DM or mixed phenotype. RESULTS Based on the presence of two high-risk HLA-DQA1/B1 haplotypes, 39% of African Americans, 81% of Caucasians, 70% of Latinos, and 67% of mixed-others were at high genetic risk. In patients with T1DM, 41% of African Americans, 80% of Caucasians, 73% of Latinos, and 63% of mixed-others were genetically susceptible. Thirty-one percent of African Americans, including 29% of those with T1DM, could not be characterized because their haplotypes had unknown T1DM associations. These unusual haplotypes comprised 11% in T1DM, 14% in T2DM, and 8% in patients with mixed phenotype. CONCLUSIONS Fifty-nine percent of childhood-onset patients with T1DM were identified with high genetic risk based on known HLA-DQA1/B1 associations. Many non-Caucasian patients carry HLA-DQ alleles whose association with T1DM is undetermined. Genetic approaches can provide insights into the etiology and appropriate treatment of childhood-onset diabetes but only if sufficient data are available in diverse ethnic groups.

Abstract
AIM To explore whether it is possible to predict a child's eventual diabetes phenotype using characteristics at initial presentation, we reassessed 111 young patients on average 7.8 ± 4.2 (2.2-19.7) [mean ± SD (range)] years after diagnosis. METHODS Medical records at diagnosis for 111 patients, aged 0-17, were compared with their follow-up characteristics including stimulated C-peptide (CP) and islet autoantibodies (AB). RESULTS Initially, 18 patients were obese; 9 displayed other type 2 diabetes (T2DM) features (polycystic ovary syndrome, acanthosis, diagnosed T2DM); the remaining 84 had a classic type 1 diabetes (T1DM) presentation. At follow-up, 83 patients (75%) with no measured CP were classified as T1DM; 17 (15%) were CP+ and AB- and thus considered T2DM. Eleven patients with both T1DM and T2DM features were classified as having mixed diabetes phenotype (MDM). One-fifth (22 subjects) changed presumed phenotype at follow-up. In multivariable models, T1DM patients were younger at diagnosis, had higher initial glucose values, were more likely to have experienced ketoacidosis, and less likely to be obese or of African American ethnicity. CONCLUSIONS/INTERPRETATION Ten percent of subjects had MDM and 15% had T2DM at ∼8 years' duration. Although no onset feature was completely reliable, ketoacidosis and hyperglycemia were more likely to predict T1DM; obesity and African American ethnicity made T2DM more likely. At diagnosis, features of T2DM in addition to obesity were strongly predictive of eventual T2DM phenotype. Given the significant percentage who changed or had mixed phenotype, careful tracking of all young people with diabetes is essential to correctly determine eventual disease type.
