Abstract
Aims Diabetic ketoacidosis (DKA) is not well characterised in New Zealand. This study is aimed at characterising the change in epidemiology and severity of DKA from 2000 to 2019 at a tertiary hospital in the Waikato region of New Zealand. Methods A retrospective clinical data review of all patients admitted to Waikato District Health Board hospitals with DKA was undertaken. Characteristics and severity of DKA were assessed by type of DKA admission (diagnosed at admission, nonrecurrent, and recurrent), ethnicity, social deprivation, intensive care unit (ICU) admission, and length of hospital stay, with linear regression reporting on changes over time. Results There were 1254 admissions for DKA (564 individual patients), two-thirds being recurrent events. Nonrecurrent DKA patients were younger, whilst recurrent admissions for DKA were associated with T1D, female gender, greater socioeconomic deprivation, and rural living (all P values < 0.01). DKA admission increased 8-fold between 2000 and 2019, mostly due to an increased number of recurrent events, particularly in Māori and female patients (P < 0.001). ICU admissions increased over time (P < 0.001) whilst length of hospital stay trended down (P = 0.031). Conclusions The rise in recurrent DKA is concerning, particularly in youth and indigenous Māori. Healthcare inequities need to be addressed, including adequate access to mental health support to ensure optimal outcomes for all patients with diabetes.

Passanisi S, Salzano G, Basile P, Bombaci B, Caime F, Rulli I, Valenzise M, Gitto E, Lombardo F. Prevalence and clinical features of severe diabetic ketoacidosis treated in pediatric intensive care unit: a 5-year monocentric experience. Ital J Pediatr 2023; 49:58. [PMID: 37210518 PMCID: PMC10199737 DOI: 10.1186/s13052-023-01448-1] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/24/2022] [Accepted: 03/23/2023] [Indexed: 05/22/2023] Open
Abstract
BACKGROUND Diabetic ketoacidosis (DKA) is one of the most alarming concerns in the management of type 1 diabetes (T1D) in pediatric age. Prevalence of DKA at the onset of diabetes ranges from 30 to 40%. In selected cases of severe DKA, admission to pediatric intensive care unit (PICU) should be considered. METHODS This study aims to assess the prevalence of severe DKA treated in PICU in our 5-year monocentric experience. Secondary outcome of the study was to describe the main demographical and clinical features of individuals who required admission to PICU. All clinical data were collected by retrospectively reviewing the electronic medical records of children and adolescents with diabetes hospitalized in our University Hospital from January 2017 to December 2022. RESULTS During the study period, 103 children and adolescents were newly diagnosed with T1D. Among these, 51.5% presented clinical criteria for DKA and almost 10% needed to be treated in PICU. A higher rate of new T1D diagnoses was observed in 2021, as well as episodes of severe DKA being more frequent than in previous years. Due to severe clinical manifestations of DKA, 10 subjects (9.7%) with T1D onset needed to be treated in PICU. Of these, four children were younger than 5. The great majority came from a low household income and some of them had also immigrant background. The most common complication of DKA was acute kidney injury presented by four children. Other complications were cerebral edema, papilledema and acute esophageal necrosis. A 15-year-old girl had deep vein thrombosis (DVT) that evolved into multiple organ failure leading to death. CONCLUSIONS Our findings demonstrated that severe DKA is still quite common in children and adolescents at T1D onset, especially in some areas such as Southern Italy. Public awareness campaigns should be increasingly promoted to facilitate the recognition of early symptoms of diabetes and to reduce morbidity and mortality related to DKA.

Abstract
IMPORTANCE Presenting with diabetic ketoacidosis (DKA) at onset of type 1 diabetes (T1D) remains a risk. Following a 2011 systematic review, considerable additional articles have been published, and the review required updating. OBJECTIVE To evaluate factors associated with DKA at the onset of T1D among pediatric patients. EVIDENCE REVIEW In this systematic review, PubMed, Embase, Scopus, CINAHL, Web of Science, and article reference lists were searched using the population, intervention, comparison, outcome search strategy for primary research studies on DKA and T1D onset among individuals younger than 18 years that were published from January 2011 to November 2021. These studies were combined with a 2011 systematic review on the same topic. Data were pooled using a random-effects model. FINDINGS A total of 2565 articles were identified; 149 were included, along with 46 from the previous review (total 195 articles). Thirty-eight factors were identified and examined for their association with DKA at T1D onset. Factors associated with increased risk of DKA were younger age at T1D onset (<2 years vs ≥2 years; odds ratio [OR], 3.51; 95% CI, 2.85-4.32; P < .001), belonging to an ethnic minority population (OR, 0.40; 95% CI, 0.21-0.74; P = .004), and family history of T1D (OR, 0.46; 95% CI, 0.37-0.57; P < .001), consistent with the 2011 systematic review. Some factors that were not associated with DKA in the 2011 systematic review were associated with DKA in the present review (eg, delayed diagnosis: OR, 2.27; 95% CI, 1.72-3.01; P < .001). Additional factors associated with risk of DKA among patients with new-onset T1D included participation in screening programs (OR, 0.35; 95% CI, 0.21-0.59; P < .001) and presentation during the COVID-19 pandemic (OR, 2.32; 95% CI, 1.76-3.06; P < .001). CONCLUSIONS AND RELEVANCE In this study, age younger than 2 years at T1D onset, belonging to an ethnic minority population, delayed diagnosis or misdiagnosis, and presenting during the COVID-19 pandemic were associated with increased risk of DKA. Factors associated with decreased risk of DKA included greater knowledge of key signs or symptoms of DKA, such as a family history of T1D or participation in screening programs. Future work should focus on identifying and implementing strategies related to these factors to reduce risk of DKA among new patients with T1D.

Abstract
OBJECTIVES Diabetic ketoacidosis (DKA) is a life-threatening complication of type 1 diabetes (T1D). The aim of this study is to analyze the incidence, clinical characteristics, management and outcome of children presenting with DKA in new-onset T1D from 2008 to 2018 in Hong Kong. METHODS Data was extracted from the Hong Kong Childhood Diabetes Registry. All subjects less than 18 years with newly diagnosed T1D from 1 January 2008 to 31 December 2018 managed in the public hospitals were included. Information on demographics, laboratory parameters, DKA-related complications and management were analyzed. RESULTS In the study period, there were 556 children with newly diagnosed T1D in our registry and 43.3% presented with DKA. The crude incidence rate of new-onset T1D with DKA was 1.79 per 100,000 persons/year (CI: 1.56-2.04). Subjects presenting with DKA were younger (9.5 ± 4.5 vs. 10.5 ± 4.4, p=0.01) and had shorter duration of symptoms (4.2 ± 5.9 days vs. 10.6 ± 17.1 days, p<0.01). Regarding management, up to 12.4% were given insulin boluses and 82.6% were started on insulin infusion 1 h after fluid resuscitation. The rate of cerebral edema was 0.8% and there was no mortality. CONCLUSIONS Younger age and shorter duration of symptoms were associated with DKA in new-onset T1D. Despite availability of international guidelines, there was inconsistency in acute DKA management. These call for a need to raise public awareness on childhood diabetes as well as standardization of practice in management of pediatric DKA in Hong Kong.

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. PLoS One 2022; 17:e0264545. [PMID: 36136973 PMCID: PMC9498969 DOI: 10.1371/journal.pone.0264545] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2021] [Accepted: 02/12/2022] [Indexed: 11/19/2022] Open
Abstract
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.

Abstract
Background There is a lack of published studies on incidence of type 1 diabetes (T1D) and diabetic ketoacidosis (DKA) in Thailand. We aimed to estimate the national prevalence and incidence of T1D and DKA. Methods Using Thailand's nationwide population-based longitudinal data covering 69 million individuals, we included the entire children and adolescents recorded in the database. Diseases were identified using ICD-10 codes. We investigated the prevalence of T1D and cumulative incidence of T1D, T1D referral, DKA, and mortality risk of DKA in five years from 2015 to 2020. T1D and DKA annual incidence were also estimated. We present findings for the total population and by sex, age, and urban-rural residencies. Findings A total of 19,784,781 individuals aged less than 20 years were identified in 2015. The crude T1D prevalence in 2015 was 17·6 per 100,000 and crude T1D incidence rate was 5·0 per 100,000. T1D prevalence and cumulative incidence were significantly higher in older children (p < 0·001) and females (p < 0·001) than their counterparts. Among those with T1D, cumulative incidence of T1D referral was 42·4%. It was highest amongst children aged 5–14 years and was significantly higher among females (all p < 0·05). The crude DKA incidence rate at any point after diagnosis was 10·8%. The cumulative incidence of DKA was significantly higher in females and peaked in individuals aged 5–14 years (all p < 0·001). The DKA mortality risk was 258·2 per 100,000. Interpretation Older children and females had higher T1D prevalence. The DKA cumulative incidence and mortality risk were relatively low, and such incidence was peak in individuals aged 5–14 years. Funding Harvard University.

Abstract
OBJECTIVE The Environmental Determinants of Diabetes in the Young (TEDDY) study is uniquely capable of investigating age-specific differences associated with type 1 diabetes. Because age is a primary driver of heterogeneity in type 1 diabetes, we sought to characterize by age metabolic derangements prior to diagnosis and clinical features associated with diabetic ketoacidosis (DKA). RESEARCH DESIGN AND METHODS The 379 TEDDY children who developed type 1 diabetes were grouped by age at onset (0-4, 5-9, and 10-14 years; n = 142, 151, and 86, respectively) with comparisons of autoantibody profiles, HLAs, family history of diabetes, presence of DKA, symptomatology at onset, and adherence to TEDDY protocol. Time-varying analysis compared those with oral glucose tolerance test data with TEDDY children who did not progress to diabetes. RESULTS Increasing fasting glucose (hazard ratio [HR] 1.09 [95% CI 1.04-1.14]; P = 0.0003), stimulated glucose (HR 1.50 [1.42-1.59]; P < 0.0001), fasting insulin (HR 0.89 [0.83-0.95]; P = 0.0009), and glucose-to-insulin ratio (HR 1.29 [1.16-1.43]; P < 0.0001) were associated with risk of progression to type 1 diabetes. Younger children had fewer autoantibodies with more symptoms at diagnosis. Twenty-three children (6.1%) had DKA at onset, only 1 (0.97%) of 103 with and 22 (8.0%) of 276 children without a first-degree relative (FDR) with type 1 diabetes (P = 0.008). Children with DKA were more likely to be nonadherent to study protocol (P = 0.047), with longer duration between their last TEDDY evaluation and diagnosis (median 10.2 vs. 2.0 months without DKA; P < 0.001). CONCLUSIONS DKA at onset in TEDDY is uncommon, especially for FDRs. For those without familial risk, metabolic monitoring continues to provide a primary benefit of reduced DKA but requires regular follow-up. Clinical and laboratory features vary by age at onset, adding to the heterogeneity of type 1 diabetes.

Abstract
BACKGROUND There is significant global variation in the prevalence of diabetic ketoacidosis (DKA) at diagnosis among youth with type 1 diabetes (T1D). However, data for youth with type 2 diabetes (T2D) are limited, even in developed countries. We compared the prevalence of DKA at diagnosis among individuals with T1D and T2D from the SEARCH for Diabetes in Youth (SEARCH) and the Registry of Youth Onset Diabetes in India (YDR) registries. METHODS We harmonized the SEARCH and YDR registries to the structure and terminology in the Observational Medical Outcome Partnership Common Data Model. Data used were from youth with T1D and T2D diagnosed before 20 years and newly diagnosed between 2006 and 2012 in YDR and 2009 and 2012 in SEARCH. RESULTS There were 5366 US youth (4078 with T1D, 1288 with T2D) and 2335 Indian youth (2108 with T1D, 227 with T2D). More than one third of T1D youth enrolled in SEARCH had DKA at diagnosis which was significantly higher than in YDR (35.3% vs 28.7%, P < .0001). The burden of DKA in youth with T1D was significantly higher among younger age groups; this relationship was similar across registries (P = .4). The prevalence of DKA among T2D in SEARCH and YDR were 5.5% and 6.6% respectively (P = .4). CONCLUSIONS There is significant burden of DKA at diagnosis with T1D among youth from United States and India, especially among the younger age groups. The reasons for this high prevalence are largely unknown but are critical to developing interventions to prevent DKA at diagnosis.

Abstract
Diabetic ketoacidosis (DKA) is the end result of insulin deficiency in type 1 diabetes mellitus (T1D). Loss of insulin production leads to profound catabolism with increased gluconeogenesis, glycogenolysis, lipolysis, and muscle proteolysis causing hyperglycemia and osmotic diuresis. High levels of counter-regulatory hormones lead to enhanced ketogenesis and the release of 'ketone bodies' into the circulation, which dissociate to release hydrogen ions and cause an overwhelming acidosis. Dehydration, hyperglycemia, and ketoacidosis are the hallmarks of this condition. Treatment is effective repletion of insulin, fluids and electrolytes. Newer approaches to early diagnosis, treatment, and prevention may diminish the risk of DKA and its childhood complications including cerebral edema. However, the potential for some technical and pharmacologic advances in the management of T1D to increase DKA events must be recognized.

Abstract
Objective Despite the guidelines, significant variations can be encountered in initial therapy for pediatric diabetic ketoacidosis (DKA) in the prehospital setting. These variations occur mostly in fluid administration, insulin dosing, route of administration, and other aspects of the initial resuscitation and stabilization. The aim was to identify the effect of transport care on outcomes in children with DKA admitted to the emergency department (ED). Methods Patients admitted to a tertiary-care pediatric ED between 2015-2019 with a diagnosis of DKA were retrospectively identified. Details of pre-pediatric ED care, including transport modality, patient demographics, clinical features, laboratory evaluation, fluid therapy, insulin dosing, and short-term outcome were recorded. Results The study cohort included 147 episodes of DKA in 136 patients aged 9 months-21 years. Emergency Medical Service (EMS) transported only 37.4% of cases. EMS utilization rate was significantly higher (p=0.003) in severe cases, most of whom were >10 years (p=0.04). During transport 85% received intravenous fluid bolus. Use of fluids other than normal saline was significantly higher when transport time was >30 minutes (p=0.001). Acute kidney injury and cerebral edema developed in 21.7% and 7.4% of episodes, respectively. These complications were more common in the EMS transport group. Pediatric intensive care admission rate was also higher in the EMS compared to the non-EMS group (p=0.01). Conclusion Parents did not call the ambulance for most cases although a higher complication rate occurred in EMS patients. EMS providers and referral facilities should improve their knowledge of pediatric DKA.

Abstract
BACKGROUND Diabetic ketoacidosis (DKA) is a potentially life threatening acute complication of Type I diabetes mellitus (T1DM). This study aimed to determine the frequency and clinical characteristics of pediatric DKA at diagnosis of new-onset T1DM in Khartoum during 2000-2017 period. METHODS The study was retrospective and involved review of medical files of children (<15 years) with T1DM in the city hospitals and diabetes centers. RESULTS The overall frequency of DKA among T1DM children at onset of disease diagnosis was 17.6% (173/982). The episodes of DKA increased from 26% in first 6- year period (2000-2005) to 46.3% in the last 6-year period (2011-2012; p<0.001). No significant difference in the frequency of DKA was observed according to gender (p=0.9) and age (p=0.24). Compared to other age groups, the severity of DKA (pH<7.1) was higher in pre-school children (p<0.01). Approximately, 5% of patients were complicated with cerebral edema with a mortality rate of 1.7%. CONCLUSION The DKA frequency at diagnosis of childhood T1DM in Khartoum was lower than previous reports. In addition, the severity of DKA was high among pre-school age children with a relatively high mortality rate when compared to the global rate.

Abstract
INTRODUCTION Diabetic ketoacidosis (DKA) is a serious complication of diabetes. DKA is associated with poorer cognition in children with type 1 diabetes (T1D), but whether this is the case in older adults with T1D is unknown. Given the increasing life expectancy in T1D, understanding the role of DKA on brain health in older adults is crucial. RESEARCH DESIGN AND METHODS We examined the association of DKA with cognitive function in 714 older adults with T1D from the Study of Longevity in Diabetes. Participants self-reported lifetime exposure to DKA resulting in hospitalization; DKA was categorized into 0 hospitalization, 1 hospitalization or ≥2 hospitalizations (recurrent DKA). Global and domain-specific cognition (language, executive function/psychomotor speed, episodic memory and simple attention) were assessed. The association of DKA with cognitive function was evaluated via linear and logistic regression models. RESULTS Twenty-eight percent of participants (mean age=67 years; mean age at diagnosis=28 years; average duration of diabetes=39 years) reported a lifetime history of DKA resulting in hospitalization (18.5% single DKA; 9.7% recurrent DKA). In fully adjusted models, those with recurrent DKA had lower global cognitive function (β=-0.13; 95% CI -0.22 to 0.02) and lower scores on the executive function/psychomotor speed domain (β=-0.34; 95% CI -0.51 to 0.17). Individuals with recurrent DKA were also more likely to have the lowest level of cognitive function on the executive function/psychomotor speed domain (defined as 1.5 SD below the population mean; OR=3.26, 95% CI 1.43 to 7.42). CONCLUSIONS Among 714 older adults with T1D, recurrent DKA was associated with lower global cognitive function, lower scores on the executive function/psychomotor speed domain and 3.3 times greater risk of having the lowest level of cognitive function in our sample on the executive function/psychomotor speed domain. These findings suggest that recurrent DKA may negatively impact the brain health of older patients with T1D and highlight the importance of DKA prevention.

Abstract
BACKGROUND Childhood diabetes mellitus is a poorly researched topic in Nigeria. Its contribution to morbidity and mortality is vague. This study intends to provide additional information to the background data in Nigeria and hopefully proffers strategies to improving the outcome of this disease. METHODS This is a retrospective descriptive study of all children managed for childhood diabetes mellitus at the Ekiti State University Teaching Hospital (EKSUTH) and LAUTECH Teaching Hospital (LTH), South West Nigeria, over a 10 year period. Relevant information was obtained from the case notes of all affected children. Data obtained were analysed with SPSS version 20 software. RESULTS A total of 20 children were treated for diabetes mellitus (DM); there were 7 (35.0%) boys and 13 (65.0%) girls giving a M:F ratio of 1.0:1.9. Age range at presentation was 5 to 16 years and the mean age at presentation was 12.7 ± 2.89 years. Diabetic ketoacidosis (DKA) was the most common form of presentation in 13 (65.0%). Most [18 (90.0%)] of the patients had type 1 DM. Type 2 DM and glucocorticoid-induced diabetes mellitus were recorded in a case each, Eighteen (90%)patients had not been previously diagnosed by any form of screening prior to their presentation and admission in the hospital. Seven (35.0%) of the patient's care were affected by parental financial constraints. Five mortalities were recorded and one left against medical advice while the majority [14 (70.4%)] were discharged well and alive. The association between the greater numbers of deaths recorded in children with financial constraints was statistically significant (p < 0.05). CONCLUSION Type 1 DM remains the most predominant form of diabetes in children and most of the patients presented in DKA. The proportion of deaths in this study is unacceptably high. There is a need to proffer strategies for earlier detection and management of children with diabetes mellitus prior to the onset or development of DKA and there is a need to assist with the funding of the care of children with diabetes mellitus.

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

Abstract
OBJECTIVE While diabetic ketoacidosis (DKA) is common in youth at the onset of the diabetes, the excess costs associated with DKA are unknown. We aimed to quantify the health care services use and medical care costs related to the presence of DKA at diagnosis of diabetes. RESEARCH DESIGN AND METHODS We analyzed data from the U.S. MarketScan claims database for 4,988 enrollees aged 3-19 years insured in private fee-for-service plans and newly diagnosed with diabetes during 2010-2016. Youth with and without DKA at diabetes diagnosis were compared for mean health care service use (outpatient, office, emergency room, and inpatient visits) and medical costs (outpatient, inpatient, prescription drugs, and total) for 60 days prior to and 60 days after diabetes diagnosis. A two-part model using generalized linear regression and logistic regression was used to estimate medical costs, controlling for age, sex, rurality, health plan, year, presence of hypoglycemia, and chronic pulmonary condition. All costs were adjusted to 2016 dollars. RESULTS At diabetes diagnosis, 42% of youth had DKA. In the 60 days prior to diabetes diagnosis, youth with DKA at diagnosis had less health services usage (e.g., number of outpatient visits: -1.17; P < 0.001) and lower total medical costs (-$635; P < 0.001) compared with youth without DKA at diagnosis. In the 60 days after diagnosis, youth with DKA had significantly greater health care services use and health care costs ($6,522) compared with those without DKA. CONCLUSIONS Among youth with newly diagnosed diabetes, DKA at diagnosis is associated with significantly higher use of health care services and medical costs.

Abstract
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.

Abstract
BACKGROUND Diabetic ketoacidosis (DKA) is the leading cause of morbidity and mortality in children with type 1 diabetes (T1D). Little is known about the association between genetic and immunological markers and the risk for DKA at onset of T1D. The aim of this study was to create a model foreseeing the onset of DKA in newly diagnosed patients. METHODS This retrospective study included 532 T1D children (aged <18 years at diagnosis) recruited in our hospital, from 1995 to 2014. DKA and its severity were defined according to the criteria of ISPAD. Genetic risk categories for developing T1D were defined according to the Belgian Diabetes Registry. Multivariate statistical analyses were applied to investigate risk factors related to DKA at diagnosis. RESULTS Overall 42% of patients presented DKA at diagnosis. This study outlined the major risk of DKA at diagnosis for younger children (<3 years) and for those belonging to ethnic minorities. Children carrying neutral genotypes had a 1.5-fold increased risk of DKA at diagnosis than those with susceptible or protective genotypes, a paradoxical observation not previously reported. Only solitary positive IA-2A increased the risk of DKA at diagnosis. The proposed model could help to predict the probability of DKA in 70% of newly diagnosed cases. CONCLUSIONS This was the first reported implication of IA-2A positivity and neutral genotypes predisposing to DKA at diagnosis regardless of its severity. Earlier diagnosis through genetic and immunological screening of high-risk children could decrease DKA incidence at diabetes onset.

Ketoacidosis at onset of type 1 diabetes in children up to 14 years of age and the changes over a period of 18 years in Saxony, Eastern-Germany: A population based register study. PLoS One 2019; 14:e0218807. [PMID: 31220176 PMCID: PMC6586407 DOI: 10.1371/journal.pone.0218807] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2019] [Accepted: 06/10/2019] [Indexed: 12/20/2022] Open
Abstract
OBJECTIVE The aim of this study was to examine the incidence trends of type 1 diabetes diagnosed with ketoacidosis in Saxony, Germany from 1999 to 2016. METHODS The population based Childhood Diabetes Registry of Saxony comprising valid data for all children aged 0-14 years diagnosed with type 1 diabetes from1999 to 2016 were used for the analyses. Direct age-standardized incidence rates were calculated and the effects of age, sex, calendar year, home districts and family history of any types of diabetes on the incidence were modelled using Poisson regression. Trend analyses for standard rate ratios of children with moderate and severe diabetic ketoacidosis versus children with type 1 diabetes with non-diabetic ketoacidosis were performed using join point regression. RESULTS The rate of ketoacidosis at the time of the type 1 diabetes diagnosis was high with 35.2% during the entire observation period in Saxony. The Poisson regression analysis indicated a statistically significant increased occurrence of diabetic ketoacidosis for younger age-groups, but no statistically significant differences between boys and girls. The join point trend analyses show that the proportion of severe and moderate ketoacidosis is increasing disproportionally to the increase in incidence of type 1 diabetes over the years. CONCLUSION Due to the observed increasing incidence of diabetes as well of diabetic ketoacidosis, an educational prevention campaign is needed in Saxony as soon as possible to aid pediatricians, general physicians as well as general public to identify the early signs of type 1 diabetes.

Abstract
Background: Diabetic ketoacidosis (DKA) is the most severe acute complication of type 1 diabetes mellitus which results in increased risk of morbidity and mortality especially in developing countries. Objective: To assess prevalence and associated factors of diabetic ketoacidosis in children and adolescents with newly diagnosed type 1 diabetes in hospitals of the Tigray region, Ethiopia. Methods: A facility based retrospective observational study design was conducted in newly diagnosed type 1 diabetic children and adolescents up to the age of 18 years who were registered in 13 general and two referral hospitals from January 1, 2013 to December 30, 2017. The diagnosis of diabetic ketoacidosis was made with the criteria below, Children presenting with polysymptoms, weight loss, vomiting, dehydration, and also the indirect signs or effects of acidosis on respiratory and central nervous systems like Kussmaul breathing, lethargy or coma and biochemically random blood sugar level >11 ml/L, glucosuria and urine ketone >+1 and diagnosed with type 1 diabetes for the first time. Descriptive, Mann-Whitney U and logistic regression analysis were carried out to describe and identify the associated factors with diabetic ketoacidosis. Results: More than three-quarters, 258/328 (78.7%) of the newly diagnosed type 1 diabetes patients, presented with diabetic ketoacidosis at initial diagnosis. Median age of diabetic ketoacidosis patients was 11 years. The patients with diabetic ketoacidosis were younger than nondiabetic ketoacidosis patients (11 vs 13 years, P=0.002). The mortality rate of diabetic ketoacidosis was 4.3%. Young age, presence of precipitating factors and symptoms of DKA/diabetes were found to be highly associated with diabetic ketoacidosis at initial diagnosis. Conclusions: The prevalence of diabetic ketoacidosis was alarmingly high. Young age group patients, precipitating factors and the presence of symptoms of diabetes/DKA like excessive drinking, vomiting and fatigue were highly associated with diabetic ketoacidosis.

Abstract
BACKGROUND Diabetic ketoacidosis at type 1 diabetes diagnosis is a preventable life-threatening complication. Canadian data on the temporal trends of the prevalence of diabetic ketoacidosis at the onset of type 1 diabetes in children are unknown. We aimed to determine the temporal changes in diabetic ketoacidosis prevalence at diabetes diagnosis in Quebec. METHODS We conducted a population-based cohort study of children (aged 1-17 yr) living in Quebec who were diagnosed with diabetes between 2001 and 2014, using multiple health administrative linked databases available at the Institut national de santé publique du Québec through the Quebec Integrated Chronic Surveillance System. We used multivariate Poisson regression analysis with robust error variance to determine trends in the prevalence of diabetic ketoacidosis. RESULTS We found that 25.6% (1471/5741) of children presented with diabetic ketoacidosis at diabetes diagnosis. The incidence of diabetes was stable at 30 cases per 100 000 children per year during the study period. The age- and sex-standardized rates of diabetic ketoacidosis increased from 22% (95% confidence interval [CI] 17%-26%) in 2001 to 30% (95% CI 24%-36%) in 2014. The relative increase of diabetic ketoacidosis prevalence at diabetes diagnosis over the study period was 2.0% per year (rate ratio 1.02; 95% CI 1.01-1.03). INTERPRETATION Despite a stable incidence of type 1 diabetes, we found that the prevalence of diabetic ketoacidosis at diabetes onset increased between 2001 and 2014. Our findings are concerning and demonstrate a need to continue to campaign to recognize type 1 diabetes before diabetic ketoacidosis supervenes.

J Pediatr Endocrinol Metab 2019; 32:115-119. [PMID: 30699071 DOI: 10.1515/jpem-2018-0324] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/24/2018] [Accepted: 12/05/2018] [Indexed: 11/15/2022]
Abstract
Background As per the International Society for Pediatrics and Adolescent Diabetes (ISPAD) census, diabetic ketoacidosis (DKA) is the most frequent cause of diabetes-related death. In developing countries, DKA-related mortality rate ranges from 6% to 24% (Onyiriuka AN, Ifebi E. Ketoacidosis at diagnosis of type 1 diabetes in children and adolescents: frequency and clinical characteristics. J Diabetes Metab Disord 2013;12:47) in contrast to 0.15%-0.31% in the Western world (Poovazhagi V. Risk factors for mortality in children with diabetic ketoacidosis from developing countries. World J Diabetes 2014;5:932-93.). In developing countries like Pakistan, the situation is more perplexing owing to uncertain or under-reported statistics about the spectrum of the disease and its prevalence, coupled with limited access to medical care and experts as well as less awareness. These limitations restrict our ability to develop interventions that are patient-centered. Our main objective was to determine the severity, clinical features, bio-chemical findings and outcomes of DKA in children aged 1 month to 16 years. Subjects and methods This retrospective study included the analysis of medical and laboratory records from patients' medical charts and the electronic database of all children aged 1 month to 16 years with newly diagnosed type-1 diabetes mellitus (T1DM) complicated with ketoacidosis, who presented to the emergency department (ED) at the Aga Khan University Hospital (AKUH), between January 2009 and December 2014. Results Diabetes mellitus complicated with DKA was the predominant diagnosis (n=113 [75.83%]) among endocrine diseases in children visiting the ED. Our study witnessed an increase in the incidence of DKA particularly after 5 years of age, with more severity in females. In our study, the mortality rate was 3.4%. Conclusions Considering the high incidence and mortality rate, it is emphasized that DKA should be considered in differential diagnosis. An awareness campaign for both general pediatricians and physicians as well as for the public is needed for better outcomes.

Abstract
OBJECTIVE New-onset diabetic ketoacidosis (NO-DKA) is entirely preventable with early recognition of the symptoms of type 1 diabetes mellitus (T1D). In this study, we aimed to assess whether a simple and easily delivered educational campaign could reduce the risk of DKA. METHODS A poster highlighting key features of new-onset T1D was delivered once a year over 2 years to mailboxes of over 460 000 individual residential households in the Auckland region (New Zealand). In the first year, the campaign poster was also delivered to all general practices in the region. Families of all newly diagnosed cases of T1D in children answered a brief questionnaire to ascertain whether the campaign reached them. RESULTS Over the 24-month period covered by this study, 132 new cases of T1D were diagnosed in children and adolescents in Auckland. There were 38 cases (28.8%) of DKA, which is similar to the average over the previous 5-year period (27.0%). The caregivers of three children reported both seeing the campaign poster and seeking medical attention as a result. None of these three children were in DKA at diagnosis; they were aged 6.3 to 9.7 years, and of New Zealand European ethnicity. CONCLUSIONS A non-targeted campaign to raise awareness of diabetes symptoms in youth led only a few caregivers to seek timely medical attention. Overall, this once-yearly untargeted campaign to raise awareness of diabetes symptoms in youth had limited impact. More effective strategies are required, possibly involving sustained targeted education of medical practitioners.

Abstract
OBJECTIVE This study determined trends in hospital admission for diabetic ketoacidosis (DKA) in adults with type 1 diabetes mellitus (T1DM) and type 2 diabetes mellitus (T2DM) from 1998 to 2013 in England. RESEARCH DESIGN AND METHODS The study population included 23,246 adults with T1DM and 241,441 adults with T2DM from the Clinical Practice Research Datalink (CPRD) and Hospital Episode Statistics (HES). All hospital admissions for DKA as the primary diagnosis from 1998 to 2013 were identified. Trends in hospital admission for DKA in incidence, length of hospital stay, 30-day all-cause readmission rate, and 30-day and 1-year all-cause mortality rates were determined using joinpoint regression, negative binomial regression, and logistic regression models. RESULTS For T1DM, the incidence of hospital admission for DKA increased between 1998 and 2007 and remained static until 2013. The incidence in 2013 was higher than that in 1998 (incidence rate ratio 1.53 [95% CI 1.09-2.16]). For T2DM, the incidence increased 4.24% (2.82-5.69) annually between 1998 and 2013. The length of hospital stay decreased over time for both diabetes types (P ≤ 0.0004). Adults with T1DM were more likely to be discharged within 2 days compared with adults with T2DM (odds ratio [OR] 1.28 [1.07-1.53]). The 30-day readmission rate was higher in T1DM than in T2DM (OR 1.61 [1.04-2.50]) but remained unchanged for both diabetes types over time. Trends in 30-day and 1-year all-cause mortality rates were also stable, with no difference by diabetes type. CONCLUSIONS In the previous two decades in England, hospitalization for DKA increased in adults with T1DM and in those with T2DM, and associated health care performance did not improve except decreased length of hospital stay.

Abstract
Aims We conducted a national survey to clarify the characteristics and clinical course of type 1 diabetes related to anti-programmed cell death-1 therapy. Methods We analyzed the detailed data of 22 patients that were collected using a Japan Diabetes Society survey and a literature database search. Results Among the 22 patients, 11 (50.0%) met the criteria for fulminant type 1 diabetes and 11 (50.0%) met the criteria for acute-onset type 1 diabetes. The average patient age was 63 years. The mean duration between the date of the first anti-PD-1 antibody injection and development of type 1 diabetes was 155 days and ranged from 13 to 504 days. Flu-like symptoms, abdominal symptoms, and drowsiness were observed in 27.8, 31.6, and 16.7% patients, respectively. Mean ± standard deviation or median (first quartile-third quartile) glucose levels, HbA1c levels, urinary C-peptide immunoreactivity levels, and fasting serum C-peptide immunoreactivity levels were 617 ± 248 mg/dl, 8.1 ± 1.3%, 4.1 (1.4-9.4) μg/day, and 0.46 (0.20-0.70) ng/ml, respectively. Seventeen of 20 patients (85.0%) developed ketosis, and 7 of 18 patients (38.9%) developed diabetic ketoacidosis. Ten of 19 patients (52.6%) showed at least one elevated pancreatic enzyme level at the onset and two of seven patients showed this elevation before diabetes onset. Only one of 21 patients was anti-glutamic acid decarboxylase antibody positive. Conclusions Anti-programmed cell death-1 antibody-related type 1 diabetes varies from typical fulminant type 1 diabetes to acute-onset type 1 diabetes. However, diabetic ketoacidosis was frequently observed at the onset of diabetes. An appropriate diagnosis and treatment should be provided to avoid life-threatening metabolic alterations.

Abstract
We studied the frequency of diabetic ketoacidosis (DKA) in children at diagnosis of type 1 diabetes (T1D) in a region where newborn infants have since 1995 been recruited for genetic screening for human leukocyte antigen (HLA)-conferred disease susceptibility and prospective follow up. The aim was to study whether participation in newborn screening and follow up affected the frequency of DKA, and to follow the time trends in DKA frequency. We first included children born in Oulu University Hospital since 1995 when the prospective studies have been ongoing and diagnosed with T1D <15 years by 2015 (study cohort 1, n = 517). Secondly, we included all children diagnosed with T1D <15 years in this center during 2002-2014 (study cohort 2, n = 579). Children who had an increased genetic risk for T1D and participated in prospective follow up had low frequency of DKA at diagnosis (5.0%). DKA was present in 22.7% of patients not screened for genetic risk, 26.7% of those who were screened but had not an increased risk and 23.4% of children with increased genetic risk but who were not followed up. In study cohort 2 the overall frequency of DKA was 18.5% (13.0% in children <5 years, 14.0% in children 5-10 years and 28.6% in children ≥10 years at diagnosis; P<.001). In children <2 years the frequency of DKA was 17.1%. Participation in prospective follow-up studies reduces the frequency of DKA in children at diagnosis of T1D, but genetic screening alone does not decrease DKA risk.

Abstract
OBJECTIVE To explore whether children diagnosed with type 1 diabetes during islet autoantibody surveillance through The Environmental Determinants of Diabetes in the Young (TEDDY) study retain greater islet function than children diagnosed through the community. METHODS TEDDY children identified at birth with high-risk human leukocyte antigen and followed every 3 months until diabetes diagnosis were compared to age-matched children diagnosed with diabetes in the community. Both participated in long-term follow up after diagnosis. Hemoglobin A1c (HbA1c) and mixed meal tolerance test were performed within 1 month of diabetes onset, then at 3, 6, and 12 months, and biannually thereafter. RESULTS Comparison of 43 TEDDY and 43 paired control children showed that TEDDY children often had no symptoms (58%) at diagnosis and none had diabetic ketoacidosis (DKA) compared with 98% with diabetes symptoms and 14% DKA in the controls (P < 0.001 and P = 0.03, respectively). At diagnosis, mean HbA1c was lower in TEDDY (6.8%, 51 mmol/mol) than control (10.5%, 91 mmol/mol) children (P < 0.0001). TEDDY children had significantly higher area under the curve and peak C-peptide values than the community controls throughout the first year postdiagnosis. Total insulin dose and insulin dose-adjusted A1c were lower throughout the first year postdiagnosis for TEDDY compared with control children. CONCLUSIONS Higher C-peptide levels in TEDDY vs community-diagnosed children persist for at least 12 months following diabetes onset and appear to represent a shift in the disease process of about 6 months. Symptom-free diagnosis, reduction of DKA, and the potential for immune intervention with increased baseline C-peptide may portend additional long-term benefits of early diagnosis.

Abstract
The aim of this study was to identify the risk factors for presence and severity of diabetic ketoacidosis (DKA) at the onset of type 1 diabetes mellitus (T1DM) in Korean children and adolescents. A retrospective chart review of children and adolescents newly diagnosed with T1DM was conducted in seven secondary and tertiary centers in Korea. Eligible subjects were < 20 years of age and had records on the presence or absence of DKA at the time of T1DM diagnosis. DKA severity was categorized as mild, moderate, or severe. Data were collected on age, height, body weight, pubertal status, family history of diabetes, delayed diagnosis, preceding infections, health insurance status, and parental education level. A total of 361 patients (male 46.3%) with T1DM were included. Overall, 177 (49.0%) patients presented with DKA at T1DM diagnosis. Risk factors predicting DKA at T1DM diagnosis were age ≥ 12 years, lower serum C-peptide levels, presence of a preceding infection, and delayed diagnosis. Low parental education level and preceding infection increased the severity of DKA. These results suggest that alertness of the physician and public awareness of diabetes symptoms are needed to decrease the incidence and severity of DKA at T1DM diagnosis.

Abstract
In the recent years we have been observing an increased incidence of type 1 diabetes in children and adolescents. This leads to a more frequent acute complication of type 1 diabetes among children with hyperglycemia. The most common of these is diabetic ketoacidosis (DKA), while cerebral edema is the most dangerous. In children with DKA, cerebral edema most often presents with clinical symptoms but may also appear in the so-called "subclinical" form. That is why the search continues for new methods of assessing and monitoring cerebral edema in the course of DKA treatment. Ultrasonographic optic nerve sheath diameter (US ONSD) assessment is performed in various clinical scenarios when cerebral edema is suspected. It is most often performed in adult patients but increasingly often in children. US ONSD assessment is useful in the treatment of DKA in children with type 1 diabetes. This manuscript provides an overview of research results available in PubMed and other available databases on the course of treatment of DKA in children with type 1 diabetes.

Abstract
This longitudinal population-based study analyses the frequency of diabetic ketoacidosis (DKA) at type 1 diabetes diagnosis in Italian children under 15 years of age, during 2004-2013. DKA was defined as absent (pH ≥ 7.30), mild/moderate (7.1 ≤ pH < 7.30) and severe (pH < 7.1). Two multiple logistic regression models were used to evaluate the time trend of DKA frequency considered as present versus absent and severe versus absent, adjusted for gender, age group and geographical area of residence at diagnosis. Overall, 9,040 cases were ascertained. DKA frequency was 40.3% (95%CI: 39.3-41.4%), with 29.1% and 11.2% for mild/moderate and severe DKA, respectively. Severe DKA increased significantly during the period (OR = 1.03, 95%CI: 1.003-1.05). Younger-age children and children living in Southern Italy compared to Central Italy were at significantly higher risk of DKA and severe DKA. Family history of type 1 diabetes and residence in Sardinia compared to Central Italy were significantly associated with a lower probability of DKA and severe DKA. The high frequency of ketoacidosis in Italy over time and high variability among age groups and geographical area of residence, strongly suggests a continuing need for nationwide healthcare strategies to increase awareness of early detection of diabetes.

Abstract
We examined the frequency and severity of diabetic ketoacidosis (DKA) in 679 children and adolescents (0-14 years) at diagnosis of Type 1 Diabetes Mellitus (T1DM) in Kuwait. Between 1(st) January 2011 and 31(st) December 2013, all newly diagnosed children with diabetes were registered prospectively in a population-based electronic register. DKA was diagnosed using standard criteria based on the levels of venous pH and serum bicarbonate. At the time of diagnosis, mild/moderate DKA was present in 24.8% of the children, while severe DKA was present in 8.8%. Incidence of ketoacidosis was significantly higher in young children less than 2 (60.7% vs 32.4% p = <0.005) compared to children 2-14 years old, and a higher proportion presented with severe DKA (21.4% vs 8.3% p = <0.05). No association was seen with gender. Significant differences were found in the incidence of DKA between Kuwaiti and non-Kuwaiti children (31.1% vs 39.8%; p < 0.05). Family history of diabetes had a protective effect on the occurrence of DKA (OR = 0.44; 95% CI = 0.27-0.71). Incidence of DKA in children at presentation of T1DM remains high at 33.6%. Prevention campaigns are needed to increase public awareness among health care providers, parents and school teachers in Kuwait.

Abstract
We examined the clinical and laboratory characteristics of children newly diagnosed with diabetes mellitus (DM) in a single-center study. We retrospectively reviewed the data of 155 children with DM between January 2000 and December 2013. Of 155 diabetic children, 87 (56.1%) were diagnosed with type 1 DM (T1DM) and 68 (43.9%) with type 2 DM (T2DM). Mean ages at diagnosis were 8.95±3.89 years (T1DM) and 13.76±2.23 years (T2DM), respectively (p<0.001). There were significant differences in HbA1c, C-peptide, and glutamic acid decarboxylase antibody levels between the T1DM and T2DM groups. Annual numbers of children with DM have increased, and since 2011 the number of children with T2DM has surpassed the number with T1DM. The most common clinical symptom in T1DM was polyuria, and 26.4% of children with T1DM presented initially with diabetic ketoacidosis. In contrast, 60.3% of T2DM children showed glucosuria in a school urine screening, and only 19.1% presented with polydipsia. The rate of positivity for at least more than one islet autoantibody was 77.1% in T1DM and 26.3% in T2DM. Serum C-peptide levels in T2DM were increased up to 12 months after onset and remained >3.59 ng/mL for 36 months. However, serum C-peptide levels in T1DM were slightly increased up to 6 months after onset and gradually decreased to 0.32 ng/mL for 36 months. The prevalence of children with DM has increased over the last 14 years, and the proportion of T2DM patients has rapidly increased since 2009. Because childhood DM is associated with several metabolic and cardiovascular complications, children should be screened for early detection of DM, especially asymptomatic T2DM in children and adolescents.

Abstract
Diabetic ketoacidosis (DKA) is a major cause of morbidity and mortality in children with type 1 diabetes mellitus (T1DM). This article examines the factors associated with DKA in children with T1DM, both at first presentation and in recurrent cases. The challenge for future research is to find effective ways to improve primary care physician and general community awareness of T1DM to reduce DKA at presentation and develop practical, cost-effective programs to reduce recurrent DKA.

Abstract
BACKGROUND Glucokinase related maturity-onset diabetes of the young (GCK-MODY) is a form of monogenic diabetes characterized by mildly elevated fasting blood sugars and HbA(1c) typically ranging from 38 to 60 mmol/mol (5.6-7.6%). It is frequently unrecognized or misdiagnosed as Type 1 or Type 2 diabetes, resulting in unnecessary pharmacologic therapy. CASE REPORT Two brothers were initially diagnosed with Type 1 diabetes mellitus. The brothers were maintained on a total daily insulin dose of 0.3-0.5 units/kg/day and had HbA(1c) values of 40-51 mmol/mol (5.8-6.8%) throughout childhood. After over 10 years of insulin treatment, the younger brother chose to discontinue his insulin therapy without informing his family or his clinician. Following cessation of insulin treatment, he did not experience any change in overall glycaemic control. Subsequent research-based genetic testing revealed a deleterious mutation in GCK in both brothers (p.Val182Met). The older brother subsequently discontinued insulin therapy and both have remained off all pharmacological therapy with good glycaemic control (HbA(1c) < 53 mmol/mol, < 7%) and no adverse complications. The family was advised to seek confirmatory genetic testing in the father and other relatives with hyperglycaemia. CONCLUSION The family described above exemplifies the rationale behind considering a genetic cause when evaluating every person with new-onset hyperglycaemia or those with atypical diabetes. The cost of genetic testing for the most common MODY causing genes may be offset by savings made in therapeutic costs. It is important that all clinicians supervising diabetes care recognize the cardinal features that distinguish GCK-MODY from other forms of diabetes.

Abstract
We assessed the incidence of diabetic ketoacidosis (DKA) in children aged <15 years with newly diagnosed type 1 diabetes mellitus (T1DM) in the Auckland Region (New Zealand) in 1999–2013, in a retrospective review of a complete regional cohort. DKA and its severity were classified according to ISPAD 2014 guidelines. Of 730 children presenting with new-onset T1DM over the 15-year time period, 195 cases had DKA of any severity (27%). There was no change in the incidence of DKA or the proportion of children with severe DKA at presentation. The incidence of DKA among children aged <2.0 years (n = 40) was 53% compared to 25% for those aged 2–14 years (n = 690; p = 0.005). In children aged 2–14 years, increasing age at diagnosis was associated with greater likelihood of DKA at presentation (p = 0.025), with the odds of DKA increasing 1.06 times with each year increase in age. Non-Europeans were more likely to present in DKA than New Zealand Europeans (OR 1.52; p = 0.048). Despite a consistent secular trend of increasing incidence of T1DM, there was no reduction in the incidence of DKA in new-onset T1DM in the Auckland Region over time. Thus, it is important to explore ways to reduce DKA risk.

Abstract
Since 1st January 2000, the PEDIAB-LR registry has listed new cases of diabetes in children under 16 years of age in the Languedoc-Roussillon region of France, in order to assess the incidence and epidemiological characteristics of children affected by diabetes. At the end of December 2010, 745 children had been registered. The characteristics of these children included an identical proportion of girls and boys, a mean age of 8 years at diagnosis, and a family history of type 1 diabetes in 8.4% of the cases. Inaugural ketoacidosis was observed in 69.5% of the patients and was severe in 23.7% of these cases. To replace intravenous insulin, a two-injection dosing regimen (in the morning and before dinner) was prescribed in 76.5% of cases, multi-injections of basal-bolus in 16%, and subcutaneous insulin infusion (insulin pump therapy) in 7.5% of cases. Between 2000 and 2010, there was no increase in overall incidence. It is noteworthy that age at diagnosis tended to decrease, but this was not statistically significant. In conclusion, the PEDIAB-LR registry is currently the only French registry on diabetes in children, analyzing many factors related to its incidence, such as age at diagnosis and the existence of ketoacidosis.

[Ketoacidosis at time of diagnosis of type 1 diabetes in children and adolescents: effect of a national prevention campaign]. Arch Pediatr 2014; 22:343-51. [PMID: 25497364 DOI: 10.1016/j.arcped.2014.11.001] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2014] [Revised: 10/03/2014] [Accepted: 11/01/2014] [Indexed: 02/02/2023]
Abstract
The aim of the study was to evaluate, after the first year of a national information campaign, the effect on the frequency and severity of diabetic ketoacidosis (DKA) at diagnosis of type 1 diabetes (T1D) in children and adolescents in France. The following data were collected during a 2-year period in people younger than 15 years of age at diagnosis of T1D, in 146 pediatric centers: age, sex, duration of symptoms, patient's previous care, clinical and biological signs, and family history of T1D. DKA was defined as pH<7.30 or bicarbonate<15mmol/L, severe DKA as pH<7.10 or bicarbonate <5mmol/L. During the 2nd year, an information campaign targeting health professionals and families was launched with the objective of reducing the time to diagnosis. Data were compared between the year before the campaign (year 0) and the first year of the campaign (year 1). The number of new cases of T1D was 1299 for year 0 and 1247 for year 1. Between year 0 and year 1, the rate of DKA decreased from 43.9% to 40.5% (P=0.08), exclusively due to the decrease of severe DKA from 14.8 to 11.4% (P=0.01). In the 0- to 5-year-old and 5- to 10-year-old age groups, the relative decrease in the rate of DKA was 13% and 15%, and 23% and 41% for severe DKA, respectively. In patients referred to the hospital by a pediatrician or who came at the family's initiative, the decrease was 34% and 7%, and 39% and 32% for severe DKA, respectively. No change was observed in the 10- to 15-year-old group or in those children who were referred by a general practitioner. In multivariate analyses, a higher DKA rate was associated with the young age of the child (<5 years), being hospitalized at the parents' initiative rather than being referred by a doctor, and the absence of a family history of T1D. A higher rate of severe DKA was associated with these last two factors but not with the child's age. The frequency of DKA at diagnosis of type 1 diabetes remains high in children and adolescents, but the first year of an information campaign decreased it. The results have also helped better define the strategy and targets of the continuing prevention campaign, to more efficiently reduce the morbidity and mortality of T1D at diagnosis in children and adolescents in France.

Abstract
OBJECTIVES To describe the demographic characteristics and clinical presentation of Omani children with type 1 diabetes mellitus at Sultan Qaboos University Hospital, Muscat, Oman. METHODS A retrospective analysis of all children with type 1 diabetes mellitus attending the Pediatric Endocrine Unit at Sultan Qaboos University Hospital, Oman from June 2006 to May 2013. RESULTS One hundred and forty-four patients were included in the study. The mean±SD of age at diagnosis was 6.7 ± 3.7 years. The median duration of symptoms was 10 days (IQR; 5-14). The most commonly reported presenting symptoms were polyuria (94%), polydipsia (82%), and weight loss (59%). Diabetic ketoacidosis at initial presentation was diagnosed in 31% of the patients. Different insulin regimens were prescribed: multiple daily injections in 109 (76%) patients, twice daily insulin regimen in 23 (16%) patients, and insulin pump therapy in 12 (8%) patients. Family history of type 1 diabetes mellitus was present in 31 (22%) patients. There were no significant differences in presenting complaints (polyuria, p=0.182; polydipsia, p=0.848), duration of symptoms (p=0.331), reported weight loss (p=0.753), or diabetic ketoacidosis at presentation (p=0.608) between patients with and without family history of type 1 diabetes mellitus. CONCLUSION Polyuria, polydipsia and weight loss are the most common presenting symptoms. Family history of type 1 diabetes mellitus is highly prevalent among the studied patients. Diabetic ketoacidosis was found to be less common in Oman compared to other diabetes centers in the Middle East.

Abstract
OBJECTIVE To estimate temporal changes in the prevalence of diabetic ketoacidosis (DKA) at diagnosis of type 1 or type 2 diabetes in youth and to explore factors associated with its occurrence. METHODS Five centers identified incident cases of diabetes among youth aged 0 to 19 years starting in 2002. DKA presence was defined as a bicarbonate level <15 mmol/L and/or a pH <7.25 (venous) or <7.30 (arterial or capillary) or mention of DKA in the medical records. We assessed trends in the prevalence of DKA over 3 time periods (2002-2003, 2004-2005, and 2008-2010). Logistic regression was used to determine factors associated with DKA. RESULTS In youth with type 1 diabetes (n = 5615), the prevalence of DKA was high and stable over time (30.2% in 2002-2003, 29.1% in 2004-2005, and 31.1% in 2008-2010; P for trend = .42). Higher prevalence was associated with younger age at diagnosis (P < .0001), minority race/ethnicity (P = .019), income (P = .019), and lack of private health insurance (P = 008). Among youth with type 2 diabetes (n = 1425), DKA prevalence decreased from 11.7% in 2002-2003 to 5.7% in 2008-2010 (P for trend = .005). Higher prevalence was associated with younger age at diagnosis (P = .001), minority race/ethnicity (P = .013), and male gender (P = .001). CONCLUSIONS The frequency of DKA in youth with type 1 diabetes, although stable, remains high, indicating a persistent need for increased awareness of signs and symptoms of diabetes and better access to health care. In youth with type 2 diabetes, DKA at onset is less common and is decreasing over time.

Abstract
OBJECTIVE The Environmental Determinants of Diabetes in the Young (TEDDY) study is designed to identify environmental exposures triggering islet autoimmunity and type 1 diabetes (T1D) in genetically high-risk children. We describe the first 100 participants diagnosed with T1D, hypothesizing that (i) they are diagnosed at an early stage of disease, (ii) a high proportion are diagnosed by an oral glucose tolerance test (OGTT), and (iii) risk for early T1D is related to country, population, human leukocyte antigen (HLA)-genotypes and immunological markers. METHODS Autoantibodies to glutamic acid decarboxylase (GADA), insulinoma-associated protein 2 (IA-2) and insulin (IAA) were analyzed from 3 months of age in children with genetic risk. Symptoms and laboratory values at diagnosis were obtained and reviewed for ADA criteria. RESULTS The first 100 children to develop T1D, 33 first-degree relatives (FDRs), with a median age 2.3 yr (0.69-6.27), were diagnosed between September 2005 and November 2011. Although young, 36% had no symptoms and ketoacidosis was rare (8%). An OGTT diagnosed 9/30 (30%) children above 3 yr of age but only 4/70 (5.7%) below the age of 3 yr. FDRs had higher cumulative incidence than children from the general population (p < 0.0001). Appearance of all three autoantibodies at seroconversion was associated with the most rapid development of T1D (HR = 4.52, p = 0.014), followed by the combination of GADA and IAA (HR = 2.82, p < 0.0001). CONCLUSIONS Close follow-up of children with genetic risk enables early detection of T1D. Risk factors for rapid development of diabetes in this young population were FDR status and initial positivity for GADA, IA-2, and IAA or a combination of GADA and IAA.

Abstract
Background Diabetic ketoacidosis (DKA) is a potentially life-threatening acute complication of type 1 diabetes mellitus (T1DM). Although the frequency of DKA as first manifestation of T1DM is higher in developing compared developed countries, there is paucity of information on its characteristics in developing countries. Methods This retrospective study determined the frequency of ketoacidosis at diagnosis of new-onset type 1 diabetes and described the clinical characteristics of the patients seen between 1996 and 2011 by auditing the hospital records of all cases. The diagnosis of diabetic ketoacidosis (DKA) was based on the presence of hyperglycaemia (blood glucose > 11 mmol/L), acidosis (serum bicarbonate < 15 mmol/L) and ketonuria (urine ketone ≥1+). Results At diagnosis of new-onset type 1 diabetes mellitus, three-quarter (77.1%) of the children and adolescents presented with DKA. Comparing the frequency of DKA during the initial 8 years (1996–2003) with the later 8 years (2004–2011), it was 81.8% vs 73.1%; p > 005. The frequency has not shown any significant declined over a 16-year period. The frequency of re-admission in ketoacidosis was 24.3%. Conclusion Three-quarter of children and adolescents present with DKA as first manifestation of T1DM with no significant decline in frequency over a 16-year period in our hospital.

Abstract
UNLABELLED Diabetic ketoacidosis (DKA) has significant morbidity and mortality and is common at diagnosis in children. The aim of this study was to determine the frequency and clinical characteristics of DKA over a 20-year period among children diagnosed with type 1 diabetes mellitus (T1DM) at University children's hospital in Belgrade, Serbia. The study population comprised of 720 patients (366 boys) diagnosed with type 1 diabetes aged <18 years between January 1992 and December 2011. Of all patients diagnosed with T1DM, 237 (32.9 %) presented with DKA. The majority had either mild (69.6 %) or moderate (22.8 %) DKA. Sixty (55.0 %) of all children under 5 years had DKA compared to sixty-two (20.9 %) in the 5- to 10-year-old group and one hundred fifteen (36.6 %) in the 11- to 18-year-old patients (p<0.01), while 2.5 % of the entire DKA cohort were in real coma. During the later 10-year period, children less often had DKA at diagnosis compared with the earlier 10-year period (28.0 vs. 37.4 %) (p<0.01), but the frequency of severe DKA was higher in the age group <5 year and in the age group >11 year during 2002-2011, compared with the earlier 10-year period (12.9 vs. 3.4 %, p<0.01 and 17.1 vs. 3.8 %, p<0.01). CONCLUSION The overall frequency of DKA in children with newly diagnosed type 1 diabetes decreased over a 20-year period at our hospital. However, children aged <5 years and adolescents are still at high risk for DKA at diagnosis.

Autoantibodies against zinc transporter 8 are related to age, metabolic state and HLA DR genotype in children with newly diagnosed type 1 diabetes. Diabetes Metab Res Rev 2013; 29:646-54. [PMID: 23861236 DOI: 10.1002/dmrr.2440] [Citation(s) in RCA: 44] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/04/2012] [Revised: 04/29/2013] [Accepted: 06/05/2013] [Indexed: 01/01/2023]
Abstract
BACKGROUND We set out to define the characteristics of humoral autoimmunity against ZnT8 in children and adolescents with newly diagnosed T1D in relation to age and metabolic status at diagnosis, human leucocyte antigen (HLA) genotype and family history of T1D. METHODS A total of 2115 subjects <15 years of age were analysed for antibodies against zinc transporter 8, ICA, GADA, IAA, IA-2A, HLA DR-DQ genotype, blood pH, plasma glucose and β-hydroxybutyrate concentrations. Their family history of T1D was also recorded. RESULTS Zinc transporter 8 antibodies (ZnT8A) were detected in 63% of the cases. ZnT8A positivity was associated with older age at diagnosis (mean 8.2 years versus 7.5 years, p < 0.001). Seven subjects (0.3%) had ZnT8A as their single autoantibody. Diabetic ketoacidosis at diagnosis was less common among subjects with ZnT8A than among those without (16% versus 20%, p = 0.012). The prevalence of ZnT8A was decreased in DR3/DR4 heterozygotes when compared with those with other DR combinations (p < 0.001). Subjects with the neutral DR13-DQB1*0604 haplotype tested more frequently positive for ZnT8A than the rest of the population (p < 0.001). A positive family history of T1D showed no association with ZnT8A prevalence or levels. CONCLUSIONS Antibodies for ZnT8 is related to age and metabolic status at diagnosis as well as HLA genotype but does not significantly improve the detection rate of β-cell autoimmunity in Finnish children and adolescents affected by T1D.

Abstract
OBJECTIVE To analyze the effect of a community-based, poster-focused prevention program on the frequency of diabetic ketoacidosis (DKA) at diabetes onset in Austria. STUDY DESIGN All newly diagnosed patients with diabetes ≤ 15 years of age were registered prospectively by the Austrian Diabetes Incidence Study Group. Registered data included initial blood glucose, pH, and ketonuria. DKA was defined as pH < 7.3 and severe DKA as pH < 7.1. Data between 1989 and 2011 were available. In autumn, 2009, a community-based prevention program similar to the Parma Campaign, in which posters were dispensed broadly, was initiated. The frequency of DKA at the onset of diabetes in the years 2005-2009 and 2010-2011 was compared. RESULTS During the study period, 4038 children were registered. A total of 37.2% presented with DKA; 26% had a mild and 11.2% a severe form. The frequency of DKA was negatively associated with age at onset. In the years before the intervention program, 26% had mild DKA compared with 27% after the intervention (not significant). The prevalence of severe DKA in the years before the campaign was 12% compared with 9.5% thereafter (not significant). No significant change in the DKA rate at onset by the prevention program could be found when we compared age groups <5, 5 to <10, and 10 to <15 years, neither for mild nor for severe DKA. CONCLUSION The frequency of DKA in children with newly diagnosed type 1 diabetes in Austria is high and did not change despite the efforts of a community-based information program.

Abstract
AIMS To identify risk factors for diabetic ketoacidosis at diagnosis of Type 1 diabetes in children and adolescents. METHODS In three time periods (1986-1987, 1996-1997 and 2006-2007) 75, 86 and 245 patients, respectively, aged < 20 years were newly diagnosed with Type 1 diabetes in one tertiary care centre. In this retrospective comparative study, data of clinical characteristics, laboratory evaluation at diagnosis, as well as demographic data were retrieved from the patients' files. Comparative analyses were performed between patients presenting with or without diabetic ketoacidosis and between the three time periods. RESULTS Patients presenting with diabetic ketoacidosis were younger (9.2 ± 4.7 vs. 10.4 ± 4.7 years; P < 0.02), thinner (weight standard deviation score -0.59 ± 1.2 vs. -0.25 ± 1.1; P = 0.002) and less frequently had a first- and/or second-degree relative with Type 1 diabetes compared with those without diabetic ketoacidosis at presentation (16.0 vs. 31.2%, respectively; P = 0.001). Children with diabetic ketoacidosis were less likely to have had relevant testing before diagnosis than children without diabetic ketoacidosis. Children aged < 2 years presented more often with diabetic ketoacidosis than the older children (85 vs. 32%; P < 0.001). Children of Ethiopian origin had a higher rate of diabetic ketoacidosis at diagnosis than the rest of the cohort (57.8 vs. 33%; P = 0.04). CONCLUSIONS Factors affecting the risk of developing diabetic ketoacidosis at diagnosis of Type 1 diabetes may be related to the degree of awareness of symptoms of diabetes among parents and primary care physicians. Prevention programmes should aim at increasing awareness and consider the application of special measures to avoid diabetic ketoacidosis in children aged < 2 years and high-risk ethnic groups.

Abstract
OBJECTIVE There are an estimated 1000 children with diabetes in Tanzania. Recently, the first two pediatric endocrinologists, trained in the European Society for Paediatric Endocrinology (ESPE)/International Society for Paediatric and Adolescent Diabetes (ISPAD) program in Nairobi, Kenya, entered practice. The purpose of this study was to prospectively assess the impact of a 6-month diabetes management and education program on glycemic control and acute complications in children and adolescents in Tanzania. RESEARCH DESIGN AND METHODS Eighty-one patients aged 3-19 yr were enrolled. All were on split-dose Insulatard (Neutral Protamine Hagedorn) and Actrapid (soluble, regular) insulin, and were given three glucose test strips per week. Children were seen in clinic an average of six times over 6 months and received 3 h of diabetes education. A structured questionnaire evaluated social demographic data and acute complications. RESULTS Despite regular clinic attendance, diabetes education, and provision of insulin, hemoglobin A1c (HbA1c) levels did not improve. Four children (5%) had HbA1c 7.5%, 22 (28%) HbA1c 7.5-10%, 9 (24%) HbA1c 11-12.5%, and 36 (44%) HbA1c >12.5%. There was a substantial reduction in severe hypoglycemia, with 17% of subjects experiencing this acute complication compared to 52% in the 6 months prior to study enrolment. Six children were admitted in diabetic ketoacidosis during the study compared to three during the previous 6 months. Twenty-six children (36%) reported missing >6 doses of insulin (but only two lacked insulin). CONCLUSIONS Diabetes education significantly reduced the risk of severe hypoglycemia, but better glycemic control of diabetes was not attained. Further study is needed to explore factors to improve glycemic control including increased testing, or perhaps different insulin regimens.

Abstract
AIMS/HYPOTHESIS We investigated the long-term impact of diabetic ketoacidosis (DKA) at onset on metabolic regulation and residual beta cell function in a Danish population with type 1 diabetes. METHODS The study is based on data from DanDiabKids, a Danish national diabetes register for children. The register provides clinical and biochemical data on patients with type 1 diabetes diagnosed in 1996-2009 and then followed-up until 1 January 2012. Repeated-measurement models were used as statistical methods. RESULTS The study population comprised 2,964 children <18 years. The prevalence of DKA at diagnosis was 17.9%. Of the total subjects, 8.3% had mild, 7.9% had moderate and 1.7% had severe DKA. DKA (moderate and severe) was associated with increased HbA1c (%) levels (0.24; 95% CI 0.11, 0.36; p = 0.0003) and increased insulin dose-adjusted HbA1c (IDAA1c, 0.51; 95% CI 0.31, 0.70; p < 0.0001) during follow-up, after adjustment for covariates. Children without a family history of diabetes were more likely to present with DKA (19.2% vs 8.8%, p < 0.0001); however, these children had a lower HbA1c (%) level over time (-0.35; 95% CI -0.46, -0.24; p < 0.0001). Continuous subcutaneous insulin infusion (CSII) was associated with a long-term reduction in HbA1c, changing the effect of DKA, after adjustment for covariates (p < 0.0001). CONCLUSIONS/INTERPRETATION DKA at diagnosis was associated with poor long-term metabolic regulation and residual beta cell function as assessed by HbA1c and IDAA1c, respectively; however, CSII treatment was associated with improvement in glycaemic regulation and residual beta cell function, changing the effect of DKA at onset in our population.

Abstract
OBJECTIVE Variability in the incidence of type 1 diabetes mellitus (T1DM) related to geographical region, ethnic background, gender, and age indicates a need for further epidemiological studies. To date, there are no reported studies on the incidence of T1DM in the pediatric age group from the Southeastern region of Turkey. To define the incidence, demographic and clinical characteristics of T1DM in children 0-14 years of age in Diyarbakir, one of the largest cities in the Southeast region of Turkey. METHODS Hospital files of patients with the diagnosis of T1DM were reviewed. Data of all patients diagnosed between 1 June 2010 and 31 May 2011 were evaluated. Population data on the 0-14 age group were obtained from the Turkish Statistical Institute (TSI) reports. RESULTS From a total of 41 T1DM patients, 24 (58.5%) were female (male: 41.5%) with a male/female ratio of 1.4. The overall annual incidence of T1DM was 7.2/10(5), being 8.7/10(5) in females and 5.7/10(5) in males. The peak incidence was found to occur at age 5-9 years in the girls and 10-14 years in the boys. Mean age at diagnosis was 8.1±3.8 years. Rate of presentation with diabetic ketoacidosis was 65.9%. Patients applied most frequently in spring and winter months. CONCLUSIONS In this first T1DM incidence study on the pediatric age group in Diyarbakir, Turkey, T1DM incidence was found to be similar to that in countries with low-middle incidence.

Abstract
OBJECTIVE To explore the relationship between family history of diabetes and frequency of diabetic ketoacidosis (DKA) at diagnosis and to analyze the possible association between HLA genotypes and DKA. DESIGN AND METHODS We recruited 510 children and adolescents aged <17 years with type 1 diabetes (T1D) and collected information on first-degree relative (FDR) history of T1D. DKA and severe DKA were defined as blood pH <7.30 and <7.10 at diabetes onset respectively. Risk categories for developing T1D were determined according to various HLA DQA1-DQB1 haplotype combination genotypes. RESULTS The frequency of DKA and severe DKA at diagnosis was 34.7 and 7.2% respectively. DKA was more frequent in younger patients (<2 years (60.0%; P<0.001)) and occurred less in children with at least one FDR affected by T1D (13.0 vs 37.4%, P<0.001). The logistic regression showed that age at diagnosis (<2 years) and increased HLA-associated risk genotypes were independent predictors of DKA (P<0.01, odds ratio (OR)=1.068 (95% confidence interval (CI) 1.021-1.117); P<0.05, OR=1.606 (95% CI 1.034-2.475)). Introducing the presence of T1D in at least one FDR in the logistic model, a significant association between DKA and age at diagnosis (<2 years; P<0.01, OR=1.072 (95% CI 1.024-1.123)) and absence of FDRs with T1D (P=0.001, OR=4.287 (95% CI 1.770-10.383)) was found, but no more with increased HLA-associated risk genotype (P=0.06, OR=1.550 (95% CI 0.992-2.423)). CONCLUSIONS HLA-associated high-risk genotypes are associated with a high chance of presenting DKA at diabetes onset. However, having at least one FDR with T1D reduced the risk of DKA regardless of HLA genotype.
