Abstract
Executive Summary This document updates the 1999 World Health Organization (WHO) classification of diabetes. It prioritizes clinical care and guides health professionals in choosing appropriate treatments at the time of diabetes diagnosis, and provides practical guidance to clinicians in assigning a type of diabetes to individuals at the time of diagnosis. It is a compromise between clinical and aetiological classification because there remain gaps in knowledge of the aetiology and pathophysiology of diabetes. While acknowledging the progress that is being made towards a more precise categorization of diabetes subtypes, the aim of this document is to recommend a classification that is feasible to implement in different settings throughout the world. The revised classification is presented in Table 1. Unlike the previous classification, this classification does not recognize subtypes of type 1 diabetes and type 2 diabetes and includes new types of diabetes ("hybrid types of diabetes" and "unclassified diabetes").

A brief campaign to prevent diabetic ketoacidosis in children newly diagnosed with type 1 diabetes mellitus: The NO-DKA Study. Pediatr Diabetes 2018; 19:1257-1262. [PMID: 30014558 DOI: 10.1111/pedi.12722] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/18/2018] [Revised: 06/07/2018] [Accepted: 07/02/2018] [Indexed: 01/30/2023] Open
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
There is little data documenting cortisol levels in children with diabetic ketoacidosis (DKA), despite the fact that untreated adrenal insufficiency (AI) could worsen the outcome of DKA. In this cross-sectional study, we assessed serum cortisol levels in 28 children with DKA and new onset type 1 diabetes mellitus evaluated at our center over a 5-year period. Average duration of diabetes-related symptoms was positively associated with age ( P = .002), and significantly lower hemoglobin A1c levels were observed in the youngest children. The mean cortisol level was 40.9 µg/dL, with a range of 7.8 to 119 µg/dL. Cortisol levels were found to be inversely associated with serum pH ( P = .007). There was no difference in the clinical outcome of the 4 patients who had cortisol levels less than 18 µg/dL. Overall, we did not find clinical or laboratory evidence of diminished cortisol reserve; however, the possibility of AI must be kept in mind when treating children with DKA.

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.

15-year incidence of diabetic ketoacidosis at onset of type 1 diabetes in children from a regional setting (Auckland, New Zealand). Sci Rep 2015; 5:10358. [PMID: 25989414 PMCID: PMC4650806 DOI: 10.1038/srep10358] [Citation(s) in RCA: 40] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2014] [Accepted: 04/10/2015] [Indexed: 12/12/2022] Open
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
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.

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/HYPOTHESIS Type 1 diabetes is the most frequent endocrine disease in children, with 65,000 children diagnosed worldwide every year. Up to 80% of these children present with diabetic ketoacidosis (DKA), which is associated with both short-term risks and long-term consequences. This study aimed to characterise the worldwide variation in presentation of type 1 diabetes to inform future interventions to reduce this excess morbidity and mortality. METHODS This was a systematic review of studies indexed on PubMed, EMBASE, Web of Science, Scopus or CINAHL before March 2011 that included unselected groups of children presenting with new-onset type 1 diabetes, reported the proportion presenting with DKA and used a definition of DKA based on measurement of pH or bicarbonate. RESULTS Sixty-five studies of cohorts comprising over 29,000 children in 31 countries were included. The frequency of DKA at diagnosis ranged from 12.8% to 80%, with highest frequencies in the United Arab Emirates, Saudi Arabia and Romania, and the lowest in Sweden, the Slovak Republic and Canada. Multivariable modelling showed the frequency of DKA was inversely associated with gross domestic product, latitude and background incidence of type 1 diabetes. CONCLUSIONS/INTERPRETATION This is the first description of the variation in frequency of DKA at presentation of type 1 diabetes in children across countries. It demonstrates large variations that may, at least in part, be explained by different levels of disease awareness and healthcare provision and suggests ways to decrease the excess morbidity and mortality associated with DKA at diagnosis.

Abstract
Diabetic ketoacidosis (DKA) is caused by absolute or relative lack of insulin. Lack of insulin leads to hyperglycemia, ketonemia, and acidosis. Prevalence of DKA at diagnosis of type 1 diabetes (T1D) varies around the world from 18 % to 84 %. Incidence of recurrent DKA is higher among females, insulin pump users, those with a history of psychiatric or eating disorder, and suboptimal socioeconomic circumstances. DKA is the most common cause of death in children with T1D. Children with DKA should be treated in experienced centers. Initial bolus of 10-20 mL/kg 0.9 % saline is followed by 0.45 %-0.9 % saline infusion. Fluid infusion should precede insulin administration (0.1 U/kg/h) by 1-2 hours. The prevention of DKA at diagnosis of diabetes can be achieved by an intensive community intervention and education of health care providers to raise awareness. Prevention of recurrent DKA requires continuous patient education and access to diabetes programs and telephone services.

Abstract
AIMS To determine whether the frequency and severity of diabetic ketoacidosis and the clinical characteristics of children at diagnosis of Type 1 diabetes mellitus have changed over the past decades among patients under surveillance of a tertiary paediatric centre. METHODS In three time-periods, 75 (1986-1987), 86 (1996-1997) and 245 (2006-2007) patients at mean age 10.1 ± 4.7 years (0.6-20.0) were diagnosed with new-onset Type 1 diabetes. Data on clinical characteristics and laboratory evaluation at diagnosis retrieved from the patients' files . Comparative analysis was performed between the three time periods. RESULTS The frequency of diabetic ketoacidosis at diagnosis was 40% in 1986-1987, 41.8% in 1996-1997 and 29.4% in 2006-2007; the last rate was significantly lower (P=0.04). No significant differences in the proportions of patients with severe or moderate diabetic ketoacidosis were found over time. Mean weight standard deviation score significantly increased from -0.72 ± 1.8 in 1986-1987 to -0.27 ± 1.2 in 2006-2007 (P<0.05), while percentage weight loss (∼6.5%) before diagnosis remained unchanged. In 2006-2007 a higher proportion of children had glucose testing at the community clinic before diagnosis, than in the earlier years (73.1 vs. 59.6%, P=0.003). CONCLUSIONS The overall frequency of diabetic ketoacidosis in children with newly diagnosed Type 1 diabetes has decreased in the past decade, although the degree of metabolic decompensation has remained unchanged.

Abstract
The object of this review is to provide the definitions, frequency, risk factors, pathophysiology, diagnostic considerations, and management recommendations for diabetic ketoacidosis (DKA) in children and adolescents, and to convey current knowledge of the causes of permanent disability or mortality from complications of DKA or its management, particularly the most common complication, cerebral edema (CE). DKA frequency at the time of diagnosis of pediatric diabetes is 10%-70%, varying with the availability of healthcare and the incidence of type 1 diabetes (T1D) in the community. Recurrent DKA rates are also dependent on medical services and socioeconomic circumstances. Management should be in centers with experience and where vital signs, neurologic status, and biochemistry can be monitored with sufficient frequency to prevent complications or, in the case of CE, to intervene rapidly with mannitol or hypertonic saline infusion. Fluid infusion should precede insulin administration (0.1 U/kg/h) by 1-2 hours; an initial bolus of 10-20 mL/kg 0.9% saline is followed by 0.45% saline calculated to supply maintenance and replace 5%-10% dehydration. Potassium (K) must be replaced early and sufficiently. Bicarbonate administration is contraindicated. The prevention of DKA at onset of diabetes requires an informed community and high index of suspicion; prevention of recurrent DKA, which is almost always due to insulin omission, necessitates a committed team effort.

Abstract
AIMS To determine the incidence and examine temporal trends of Type 1 diabetes among children aged < 18 years, in a large Israeli health organization. METHODS All incident Type 1 diabetes cases diagnosed between 2000 and 2008 were ascertained from an automated diabetes registry based on members' electronic records and validated by comparison with the Israel Juvenile Diabetes Register. RESULTS During the study period, a total of 648 incident cases of Type 1 diabetes were identified. The average annual age-and-sex-standardized incidence was 11.09 per 100,000 person-years. There was an annual 5.82% (95% CI 1.80-9.98%) rise in incidence, with a greater relative increase in toddlers under 5 years of age. Incidence increased with age and demonstrated seasonal variation. Mean age at onset of diabetes significantly (P = 0.07) decreased from 10.21 years (SD = 4.48) in 2000-2002 to 9.25 years (SD = 4.54) in 2006-2008. Among very young patients (< 5 years), average blood glucose values at diagnosis dropped from 32.4 mmol/l (SD = 9.5) to 19.5 mmol/l (SD = 11.0) over the study period, with little change in average glucose for older children. CONCLUSIONS Incidence of diagnosed Type 1 diabetes continues to increase in Israel at a rate that is high compared with similar American and European populations. At the same time, the clinical presentation of children is changing.

Abstract
The aim of the study was to determine the clinical and biochemical characteristics of type 1 diabetes mellitus (DM) at presentation in children younger than 15 years in Croatia during a 9-year period, with special attention to diabetic ketoacidosis (DKA) incidence. The registered data set comprised blood glucose, pH, serum bicarbonate levels, and clinical symptoms at disease manifestation. During the study period, 692 children were diagnosed with type 1 DM. Polydipsia (96.7%), polyuria (96.05%), and weight loss (82.7%) were the most frequent symptoms anticipating disease detection. Enuresis was recorded in 11.55%. A total of 36.41% patients had DKA (pH < 7.3) at disease onset. During the 9-year period, the percentage of children presenting with DKA at time of diagnosis decreased from 41.67% to 33.33% (z = 1.68, p = 0.046). A positive family history of DM, the only factor with an impact on the DKA incidence rate in our population, lowers the probability of the development of ketoacidosis. This study confirms the importance of the detection of the classic symptoms of polyuria, polydipsia, and weight loss in patients with new-onset type 1 DM. The percentage of patients with DKA at diabetes onset decreased during the observed period but is still high and includes one-third of all patients. This is why in every acutely ill child, especially at a younger age, one should evaluate the possibility of type 1 DM to avoid the development of ketoacidosis.

Fluid infusion should precede insulin administration (0.1 U/kg/h) by 1-2 hours; an initial bolus of 10-20 mL/kg 0.9% saline is followed by 0.45% saline calculated to supply maintenance and replace 5%-10% dehydration. Potassium (K) must be replaced early and sufficiently. Bicarbonate administration is contraindicated. The prevention of DKA at onset of diabetes requires an informed community and high index of suspicion; prevention of recurrent DKA, which is almost always due to insulin omission, necessitates a committed team effort.

Abstract
BACKGROUND Diabetic ketoacidosis (DKA) has significant morbidity and mortality, and is common at diagnosis in children. OBJECTIVE Describe the frequency and severity of DKA at diagnosis of type 1 diabetes mellitus (T1DM) in children in Kuwait. METHODS Hospital records of 677 diabetic children less than 12 yr of age, diagnosed during the period of 2000-2006 were reviewed. DKA was defined as blood glucose > 11 mmol/L, pH < 7.3, and/or bicarbonate < 15 mmol/L with ketonuria. RESULTS Of all patients diagnosed with T1DM, 255 (37.7%) presented with DKA. The frequency of DKA was constant between 2000 and 2002 (42.7-41.5%), but decreased in the following years to 30.7% in 2006 (p < 0.005). The majority had either mild or moderate DKA (74.1%). Fifty-one (36.7%) of all children in the 0-4 yr had severe DKA compared to ten (2.9%) in the 5- to 8-yr-old group, and three (1.5%) in 9- to 12-yr-old patients (p < 0.0001). Moreover, 83% of children with severe DKA were in the 0-4 yr age group. One child (0.15%) died and twenty-seven (4%) needed intensive care unit (ICU) care. CONCLUSION Our study provides recent data on Middle Eastern population, for whom data are sparse. Although it has significantly decreased, the frequency of DKA at presentation of T1DM in children in Kuwait is still high, secondary to the high prevalence of diabetes in the community. Young children, especially those less than 2 yr old remain at high risk. Increasing the general awareness of the public as well as of pediatricians to the disease may lead to early diagnosis before the development of acidosis.

Abstract
OBJECTIVE We studied the prevalence of diabetic ketoacidosis (DKA) at diagnosis of type 1 diabetes in children in Finland. RESEARCH DESIGN AND METHODS From 2002 to 2005, data on virtually all children <15 years of age diagnosed with type 1 diabetes (n = 1,656) in Finland were collected. RESULTS DKA was present in 19.4% of the case subjects, and 4.3% had severe DKA. In children aged 0-4, 5-9, and 10-14 years, DKA was present in 16.5, 14.8, and 26.4%, respectively (P < 0.001). Severe DKA occurred in 3.7, 3.1, and 5.9%, respectively (P = 0.048). DKA was present in 30.1% and severe DKA in 7.8% of children aged <2 years. CONCLUSION The overall frequency of DKA in children is low in Finland at diagnosis of type 1 diabetes. However, both children <2 years of age and adolescents aged 10-14 years are at increased risk of DKA.

Abstract
AIM The aim of the study was to analyse the prevalence of diabetic onset ketoacidosis (DKA) during a period of 20 years (1989-2008) on a population basis in the whole of Austria. METHODS A prospective population-based incidence study (1989-2008) was performed. The registered data set comprised blood glucose, pH, ketonuria and clinical symptoms of DKA at manifestation. DKA was defined as pH < 7.3 and severe DKA as pH < 7.1. Time trends were estimated using linear regression models. RESULTS During the study period, 3331 children <15 years of age (1,797 boys and 1,534 girls) were registered with newly diagnosed type 1 diabetes. Of these, 1,238 (37.2%) presented with DKA, 855 (25.7%) had a mild and 383 (11.5%) a severe form, and one patient died at onset. DKA frequency was negatively associated with age at onset (p < 0.0001). In children <2 years the prevalence was 60%, with a higher risk for girls (70% vs 54% for boys, p < 0.05). Despite a significant increase in diabetes incidence in Austria during the observation period from 8.4 to 18.4/100,000 (p < 0.0001), no significant change in the prevalence of DKA at manifestation was observed. CONCLUSIONS The overall frequency of DKA in children with newly diagnosed type 1 diabetes in Austria is high and has not changed during the last 20 years despite a clear increase in the manifestation rate. In particular, children less than 2 years of age have a high risk of DKA at onset.

Abstract
BACKGROUND Diabetic ketoacidosis (DKA) development in children with new-onset type 1 diabetes (T1DM) is often the main consequence of delayed diagnosis. The aim of the study was to estimate the frequency of difficulties in T1DM diagnosis and to investigate if and how the demographic factors (gender, patient's age at presentation, family history of T1DM, level of maternal education, place of residence, and health service unit the patient called at) have any influence on diagnostic delays. SUBJECTS AND METHODS Retrospective analysis of 474 children (243 boys-51.27% and 231 girls -48.73%) with new-onset T1DM aged below 17 yr and living in the Pomeranian region of Poland was carried out. The delay in diagnosis was recognized if the patient was not diagnosed on the first visit because of omission, wrong interpretation of main diabetic symptoms, exclusive treatment of additional signs, or concomitant diseases. RESULTS Difficulties in diagnosing T1DM were found in 67 cases (14.13%) and they are the main cause of DKA development in these children (p = 0.00). Among the examined demographic factors, mainly the patient's age at presentation has a significant influence on diagnostic delays (p = 0.01), especially in children below 2 yr (p = 0.00). Most frequently family doctors were responsible for wrong preliminary diagnosis. CONCLUSIONS Difficulties in diagnosing T1DM are a significant cause of DKA development in children with new-onset disease. Patient's age at presentation is the main risk factor of delayed diagnosis, especially in children below 2 yr. The increase in awareness among pediatricians concerning the possibility of T1DM development in children is needed.

Abstract
OBJECTIVE To study the frequency of diabetic ketoacidosis (DKA) over a 20-year period among children diagnosed with type 1 diabetes in northern Finland. RESEARCH DESIGN AND METHODS The study population comprised 585 patients (328 boys) diagnosed with type 1 diabetes aged <15 years in the Department of Pediatrics, Oulu University Hospital, between 1 January 1982 and 31 December 2001. The data for clinical characteristics were collected retrospectively from the patients' case records. The earlier 10-year period (1982-1991) was compared with the later 10-year period (1992-2001). Two definitions for DKA were used: DKA(i) pH <7.30 or DKA(ii) pH <7.30 and/or bicarbonate <15 mmol/l. RESULTS During the later 10-year period, children less often had DKA at diagnosis [DKA(i) 15.2 vs. 22.4%, P = 0.028, and DKA(ii) 18.9 vs. 29.5%, P = 0.003]. The proportion of young children aged <5 years at diagnosis increased over time, but the frequency of DKA also was lower in this age-group during 1992-2001 compared with the earlier 10-year period [DKA(i) 17.7 vs. 32.1%, P = 0.052, and DKA(ii) 20.3 vs. 42.6%, P = 0.005]. In children aged <2 years at diagnosis, the frequency of DKA remained high during 1992-2001 [DKA(i) 39.1% and DKA(ii) 47.8%]. CONCLUSIONS The overall frequency of DKA in children with newly diagnosed type 1 diabetes decreased over a 20-year period in northern Finland. However, children aged <2 years are still at high risk for DKA at diagnosis.
