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.

Al-Abdulrazzaq D, Othman F, Qabazard S, Al-Tararwa A, Ahmad D, Al-Sanae H, Al-Kandari H. Epidemiological trends in the presentation of diabetic ketoacidosis in children newly diagnosed with type 1 diabetes from 2011 to 2017 in Kuwait. Front Endocrinol (Lausanne) 2022; 13:908458. [PMID: 36568099 PMCID: PMC9780369 DOI: 10.3389/fendo.2022.908458] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/30/2022] [Accepted: 11/25/2022] [Indexed: 12/13/2022] Open
Abstract
BACKGROUND Monitoring the trends in the presentation of T1D over decades cannot be underestimated as it provides a rich source of information on diabetes-related complications like DKA. DKA represents a medical emergency, with potentially fatal outcome, and thus the prevention of DKA is a priority in diabetes care. The aim of this study is to report on trends in the presentation of DKA in children newly diagnosed with T1D in Kuwait. MATERIAL AND METHODS This study is based on a retrospective review of children newly diagnosed with T1D aged 14 years or less at three Governmental Hospitals representing three health sectors out of the total six health sectors in the country during the period 2011-2017. RESULTS A total of 799 children (376 males and 423 females) were newly diagnosed with T1D. 287 children presented with DKA (35.9%) with only 73 children (9.1%) classified as severe. During the years 2011 to 2017, we note that the percentage of children older than 6 years of age presenting with severe DKA has decreased significantly (p=0.022). Unfortunately, this has not been replicated in children younger than 6 years. CONCLUSION This study highlights the importance of continued monitoring of clinical characteristics of children at diagnosis of T1D specifically presenting with DKA to enable diabetes care professionals to appreciate the multifaceted aspects of T1D, in particular the importance of raising awareness of the early signs of the onset of T1D with special attention to DKA and its severe consequences.

Human Leukocyte Antigen (HLA) and Islet Autoantibodies Are Tools to Characterize Type 1 Diabetes in Arab Countries: Emphasis on Kuwait. DISEASE MARKERS 2019; 2019:9786078. [PMID: 31827651 PMCID: PMC6886320 DOI: 10.1155/2019/9786078] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/12/2019] [Revised: 07/15/2019] [Accepted: 09/20/2019] [Indexed: 12/11/2022]
Abstract
The incidence rate of type 1 diabetes in Kuwait had been increasing exponentially and has doubled in children ≤ 14 years old within almost two decades. Therefore, there is a dire need for a careful systematic familial cohort study. Several immunogenetic factors affect the pathogenesis of the disease. The human leukocyte antigen (HLA) accounts for the major genetic susceptibility to the disease. The triggering agents initiate disease onset by type 1 destruction of pancreatic β-cells. Both HLA and anti-islet antibodies can be used to characterize, predict susceptibility to the disease, innovate, or delay the β-cell destruction. Evidence from prospective longitudinal studies suggested that the underlying disease process represents a continuum that begins before the symptoms are clinically evident. Autoimmunity of the functional pancreatic β-cells results in symptomatic type 1 diabetes and lifelong insulin dependence. The autoantibodies against glutamic acid decarboxylase (GADA), insulinoma antigen-2 (IA-2A), insulin (IAA), and zinc transporter-8 (ZnT-8A) comprise the most reliable biomarkers for type 1 diabetes in both children and adults. Although Kuwait is the second among the top 10 countries with a high incidence rate of type 1 diabetes, there have been no proper diagnostic and prediction tools as per the World Health Organization. The Kuwaiti Type 1 Diabetes Study (KADS) was initiated to understand the disease pathogenesis as well as the HLA and anti-islet autoantibody profile of type 1 diabetes in Kuwait. Understanding the disease sequela in a homogenous gene pool and highly consanguineous population of Kuwaitis could help solve the challenges and pathogenesis, as well as hasten the prevention, of type 1 diabetes.

Ketoacidosis at first presentation of type 1 diabetes mellitus among children: a study from Kuwait. Sci Rep 2016; 6:27519. [PMID: 27328757 PMCID: PMC4916451 DOI: 10.1038/srep27519] [Citation(s) in RCA: 29] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2015] [Accepted: 04/29/2016] [Indexed: 12/13/2022] Open
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
AIMS Diabetic ketoacidosis (DKA) is an acute and risky complication of type 1 diabetes. The aim of this study is to build the overall rate of DKA in Arab patients with type 1 diabetes in the 22 Arab nations. This is expected to tailor the healthcare approaches in Arab countries where attention is needed to save lives from the devastating consequences of DKA. METHODS The study here is a quantitative analysis of the articles indexed in four different scientific literature databases: Web of Science, PubMed, Science Direct and Scopus, from inception to June 2015. Arab patients with type 1 diabetes who presented with DKA have been captured. Key information was possible to extract for patients belong to only 12 Arab countries out of the 22 Arab patients. RESULTS Twenty-nine studies in 12 different Arab countries captured 4,688 type 1 diabetes patients with overall rates of 46.7% patients presented with DKA, ranging from a low of 17% in Egypt to a high of 100% in Morocco, Algeria and Tunisia. CONCLUSION This is the first descriptive quantitative study to determine the overall DKA rate in 46 years of studies in the Arab world of patients with type 1 diabetes; DKA rates were found to range from 17% to 100% with overall rate of 46.7%.

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
OBJECTIVES Diabetic ketoacidosis (DKA) is the leading cause of morbidity and mortality in children with type 1 diabetes mellitus (TIDM). Many patients with newly diagnosed type 1 diabetes present with DKA. The aim of this study is to determine the frequency and the clinical presentation of diabetic ketoacidosis at the diagnosis of type 1 diabetes mellitus in youths in hamadan, Western Province of Iran. METHODS The Clinical and laboratory data of a total of 200 patients under 19 years of age with newly diagnosed type 1 diabetes mellitus between 1995-2005 were retrospectively reviewed. Statistical analysis was performed using SPSS 11. RESULTS 48 (24%)of the children were presented in a state of ketoacidosis. Sever form of DKA (pH≤7.2) was observed in 54.5% of patients. The mean age at diagnosis was 7.3±5.15 years in DKA group and 8.59±3.07 in non-DKA group (p=0.22). 60.4% of patient with DKA were female whereas in the non-DKA group, 53.3% of patients were female, the difference was not significant (p=0.38). The duration of symptoms before diagnosis was 14.84±8.19 days in patients with DKA and 22.39±2.27 in the non-DKA group, (p=0.11). No significant difference was found between the age, sex and duration of the symptoms and occurance of DKA. Polydipsia (85.4) polyuria (83.3%), weakness (68.8%) and abdominal pain (52.1%) were the most frequently notified symptoms among the patients. In two cases, diagnosis of DKA was preceded by as appendicitis and the patient underwent appendectomy. CONCLUSION Frequency of DKA at onset of type 1 diabetes mellitus was significant in the studied region. However, it was lower than other regions in Asia. Polydipsia, polyuria, fatigue and abdominal pain were the most common symptoms on presentation.

Abstract
OBJECTIVE To identify the factors associated with diabetic ketoacidosis at diagnosis of type 1 diabetes in children and young adults. DESIGN Systematic review. DATA SOURCES PubMed, EMBASE, Web of Science, Scopus, and Cinahl and article reference lists. STUDY SELECTION Cohort studies including unselected groups of children and young adults presenting with new onset type 1 diabetes that distinguished between those who presented in diabetic ketoacidosis and those who did not and included a measurement of either pH or bicarbonate in the definition of diabetic ketoacidosis. There were no restrictions on language of publication. RESULTS 46 studies involving more than 24,000 children in 31 countries were included. Together they compared 23 different factors. Factors associated with increased risk were younger age (for <2 years old v older, odds ratio 3.41 (95% confidence interval 2.54 to 4.59), for <5 years v older, odds ratio 1.59 (1.38 to 1.84)), diagnostic error (odds ratio 3.35 (2.35 to 4.79)), ethnic minority, lack of health insurance in the US (odds ratio 3.20 (2.03 to 5.04)), lower body mass index, preceding infection (odds ratio 3.14 (0.94 to 10.47)), and delayed treatment (odds ratio 1.74 (1.10 to 2.77)). Protective factors were having a first degree relative with type 1 diabetes at the time of diagnosis (odds ratio 0.33 (0.08 to 1.26)), higher parental education (odds ratios 0.4 (0.20 to 0.79) and 0.64 (0.43 to 0.94) in two studies), and higher background incidence of type 1 diabetes (correlation coefficient -0.715). The mean duration of symptoms was similar between children presenting with or without diabetic ketoacidosis (16.5 days (standard error 6.2) and 17.1 days (6.0) respectively), and up to 38.8% (285/735) of children who presented with diabetic ketoacidosis had been seen at least once by a doctor before diagnosis. CONCLUSIONS Multiple factors affect the risk of developing diabetic ketoacidosis at the onset of type 1 diabetes in children and young adults, and there is potential time, scope, and opportunity to intervene between symptom onset and development of diabetic ketoacidosis for both parents and clinicians.

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
AIM The aim of this study was to investigate diabetic ketoacidosis (DKA) and cerebral oedema in the Swedish paediatric diabetes population, and to measure laboratory parameters during treatment. METHODS The Swedish National Paediatric Diabetes Registry (SWEDIABKIDS) indicates that 16% of patients < 18 years during 2000 to 2004 had DKA at onset of diabetes. Data from 1999 and 2000 was collected retrospectively from all of Sweden by questionnaire. RESULTS We identified 292 cases of DKA (pH < 7.30) in 265 children (149 at diabetes onset), aged 0.8-19.9 years. The incidence of DKA in patients with previously diagnosed diabetes was 1.4/100 patient years in 1999 and 1.7/100 in 2000. Two patients, both 11 years old with newly diagnosed diabetes, had overt symptoms of cerebral oedema and one developed neurological sequelae. This corresponds to an incidence of 0.68% (2/292) with no mortality. Symptoms of subclinical cerebral oedema after admission (headache, vomiting, lethargy) were recorded in a further 16 cases. In two of these mannitol was given, and both recovered within 1-2 h. Laboratory data was available from 253/292 episodes. During treatment for DKA, hypokalaemia (< 3.5 mmol/l) was significantly more common at onset of diabetes than in patients with established diabetes (65 vs. 28%, P < 0.001; initial prescription of potassium was 20 mmol/l). CONCLUSIONS We conclude that 16% of children with new-onset diabetes presented with DKA at diagnosis and that the incidence of DKA in children with established diabetes was 1.6/100 patient years. Cerebral oedema occurred in 0.68% of the DKA episodes.

Abstract
To identify risk factors associated with the development of diabetic ketoacidosis (DKA) in new-onset type 1 diabetes mellitus, a retrospective chart review of 139 new onset type 1 diabetes patients from 1995 to 1998 was conducted. Categorical data were examined with contingency table analysis. Age range was 0.5 to 18 years. Overall, 38% of the patients presented in DKA. Sixty-two percent of the patients with either Medicaid or no insurance presented in DKA compared to 34% of the patients with private insurance, odds ratio 3.17 (92% CI 1.2-8.3) p = 0.03. Sixty-eight percent of patients in whom the diagnosis was missed (n = 25) presented in DKA (mean age, 5.4 +/- 4.4 years) compared to 32% in whom the diagnosis was not missed (mean age, 8.8 +/- 4.0 years) odds ratio 4.6 (95% CI 1.9-11.7), p = 0.0012; age p = 0.00019. Lack of private insurance, although a risk factor for the development of DKA, did not increase the likelihood of a missed diagnosis. Lack of private insurance (a proxy for socioeconomic status) and young age are apparent risk factors for the development of ketoacidosis. Misdiagnosis by the physician at initial patient encounter is especially prevalent in the young child but not related to insurance. Both increased public awareness and greater medical alertness are necessary to reduce the high rates of DKA in new-onset type 1 diabetic children.

METHODS All 31 pediatric departments in BW and one diabetes center participated in this study. Hospital records of 2121 children below 15 yr of age were examined retrospectively. DKA was defined as glucose > 250 mg/dL, pH < 7.30 or bicarbonate < 15 mmol/L and ketonuria. Statistical analysis was done after logarithmic transformation. RESULTS 26.3% (n = 558) of all patients presented with DKA. The mean age of these patients was 7.9 yr. The frequency of DKA is higher in girls than in boys (28.9 vs. 23.8%; p = 0.0079). Those aged 0-4 yr suffered most frequently (p < 0.0001) from ketoacidosis (36.0%). The percentage of DKA in newly diagnosed cases was constant over 10 yr. 23.3% of all patients with DKA presented with an altered level of consciousness; 10.9% of these had clinical signs of coma. No deaths occurred. The proportion of ketoacidosis does not increase concurrently with the number of diabetes manifestations in winter. CONCLUSION The proportion of DKA in children with newly diagnosed diabetes mellitus is significant. In particular, children < 5 yr and girls face an increased risk. DKA may be the result of a particularly aggressive subtype of diabetes.

Abstract
Severity of Type 1 diabetes mellitus (DM) at presentation was compared between south-east Sweden and Lithuania where incidence of childhood Type 1 diabetes is three times lower than in Sweden. New cases of diabetes at age 0-15 years from August 1995 to March 1999 in south-east Sweden and from August 1996 to August 2000 in Lithuania were included. Symptoms and clinical characteristics at diagnosis were recorded. Data about the close environment were collected using questionnaires. Lithuanian children were diagnosed in a more severe condition, mean pH 7.30 and HbA(1c) 11.5% compared with mean pH 7.36 and HbA(1c) 9.7% in Swedish children (P<0.0001). More Lithuanian than Swedish children were diagnosed in ketoacidosis (pH < or = 7.2, hyperglycaemia and ketonuria), 21.3 versus 7.3% (P<0.0001). Only 4.6% of Swedish children and 1.0% of Lithuanian children had no symptoms (P=0.007). Children in families with at least one first degree relative with diabetes (12.2% in Sweden and 8.4% in Lithuania, NS) had laboratory values at diagnosis closer to normal than sporadic cases in either country. Factors predicting ketoacidosis in Sweden were an unemployed mother and absence of infections in the 6 months before diagnosis. In Lithuania it was younger age and mother with less education. Additional educational activities for doctors are needed in countries with low incidence to reduce prevalence of ketoacidosis at onset.

Abstract
Diabetic ketoacidosis (DKA) is a true pediatric and medical emergency. Diagnosis should be entertained and confirmed within 30 min of presentation. Any delay in making the diagnosis or instituting fluid and electrolyte correction is likely to increase morbidity and mortality. Slow and careful monitoring and correction of water, sodium and potassium levels should decrease DKA-associated problems with either continuous intravenous low-dose insulin or intramuscular insulin protocols designed to slowly bring the hyperglycemic and hyperosmotic state towards normal homeostasis. Special attention should be paid to potassium replenishment. Most patients do not require bicarbonate replacement. Cerebral edema, when it occurs, is associated with an approximately 50% morbidity and mortality; therefore, all attempts should be made at early recognition and prevention since treatment is less than ideal. Recurrent ketoacidosis is often related to omitted insulin and major psychosocial turmoil in the family, such as depression substance abuse, physical and/or sexual abuse. Prevention of recurrent DKA remains a major challenge for diabetologists and involves detailed assessment of family psychodynamics plus responsibility for home monitoring and insulin administration by a mature adult. Sick day guidelines should be taught and reviewed frequently in an effort to decrease ketoacidosis and metabolic decompensation during episodes of intercurrent illness.
