Diabetic Ketoacidosis in Children and Adolescents; Diagnostic and Therapeutic Pitfalls

The incidence of cerebral edema in pediatric patients with diabetic ketoacidosis: a retrospective study

OBJECTIVE

Cerebral edema is a severe and potentially fatal complication of diabetic ketoacidosis (DKA), particularly in pediatric patients. Despite its clinical significance, limited data exist on its incidence and associated risk factors in resource-limited settings. This study aimed to determine the incidence of cerebral edema in pediatric patients with DKA and investigate potential contributing factors. This retrospective study analyzed data from 270 pediatric DKA patients admitted to the Children's Medical Center Hospital, Tehran, between March 2018 and March 2020. Patients aged 1 day to 18 years were included based on standard DKA diagnostic criteria (blood glucose > 250 mg/dL, pH < 7.3, bicarbonate < 18 mEq/L, and ketonemia/ketonuria). Patients with incomplete records or pre-existing neurological conditions were excluded. The statistical analyses included independent t-tests and Fisher's exact tests.

RESULTS

The incidence of cerebral edema was 6.67%. Elevated blood glucose levels at admission were significantly associated with cerebral edema (P = 0.01), suggesting a potential role in its pathophysiology. Additionally, a strong correlation was observed between cerebral edema and ICU admission (P < 0.001), indicating a more severe disease course. The results suggest that early glucose control and neurological monitoring are critical for preventing adverse outcomes such as cerebral edema in pediatric DKA patients.

A novel function for endothelial protease-activated receptors in modulating insulin receptor activity with implications for diabetes

Thrombin, a serine protease with increased activity in diabetics, signals through protease-activated receptors 1 and 4 (PAR1/PAR4) on endothelial cells (ECs). While studying the roles of endothelial PAR1/4 in diabetic pathology, we found that mice with inducible deletion of both receptors on ECs (Par1/4 iECko ) displayed increased insulin sensitivity and were protected against streptozotocin (STZ)-induced diabetes. Concordantly, we found that cultured primary ECs with PAR1/4 deficiency had increased basal activity/phosphorylation of the insulin receptor (IR) and insulin transcytosis. This elevated IR activity correlated with reduced activity of protein tyrosine phosphatase 1B (PTP1B), which is a negative regulator of IR activity. Lastly, Par1/4 iECko mice with additional deletion of one allele of the IR gene demonstrated restoration of diabetic phenotypes after STZ treatment, indicating that these phenotypes are driven by heightened IR activity. These findings establish a novel link between endothelial PAR signaling and IR regulation, underscoring the critical role of ECs in metabolic homeostasis and identifying a potential therapeutic target for diabetes.

Clinical metabolomics in type 2 diabetes mellitus: from pathogenesis to biomarkers

As a multidimensional metabolic disorder, the disability and death rate of type 2 diabetes mellitus (T2DM) has increased over time. T2DM covers a wide range of pathological manifestations ranging from hyperglycemia to multi-organ failure, and it has the potential to evolve into acute complications, including ketosis and chronic complications such as peripheral neuropathy, retinopathy, and nephropathy. T2DM mainly occurs in microvascular and large vessels and thus it is restricted for the clinician to diagnose and prescribe. However, the pathological mechanism and clinical diagnosis are inadequate. High-throughput metabolomics, characterized by non-invasive diagnostic techniques to identify potential biomarkers and distinct stages of T2DM, has been increasingly recognized as a vigorous tool with latent capacity for clinical translation. The pathological stratification of T2DM can significantly reduce disability and mortality rates. By tracing the metabolome and associated pathways from impaired fasting blood glucose or impaired glucose tolerance to severe organ failure, the chief contributions of large, independent population-based cohorts are summarized herein. These results facilitate understanding the pathophysiology and mechanism and supports research in accurate diagnosis, risk prediction, curative effect, distinct stages, and prognosis judgment of T2DM.

Diabetic Ketoacidosis in Pediatric Emergency Medicine: Risk Factors, Myths, and Evidence-Based Management of Complications

Purpose

Diabetic ketoacidosis (DKA) is a common condition among type 1 diabetics, commonly affecting those below the age of 20.

Methods

A comprehensive literature search was conducted in databases like PubMed to identify primary studies conducted in children with DKA. Finally, 79 studies were included for qualitative synthesis.

Results

The disease is characterized by acute-onset metabolic and pathological derangements, necessitating immediate intervention. With the rising incidence, concerns have been emerging regarding the disparities in the presentation and treatment of DKA among different countries with inequitable resources. Within its management lies the common misconceptions, both among patients and primary physicians, prohibiting an optimistic approach to the disease. Pediatric children in particular need specialized treatment and care during an episode of DKA due to its long-term cognitive and neurological sequelae. Hence, efforts have been undertaken to ensure minimization of neurological damage when treating DKA. While guidelines are in place for treatment of DKA, there are considerable differences in their protocols across different regions.

Conclusion

It is imperative to analyze recent evidence and continually update treatment guidelines for DKA. Additionally, maximal efforts need to be taken to bridge the gap between different nations, allowing accessibility to equitable resources to all.

Comparison of pediatric diabetic ketoacidosis in newly diagnosed versus known patients with type 1 diabetes mellitus: A single-center study

OBJECTIVES

To compare the demographic, clinical, and biochemical characteristics of newly diagnosed versus known patients with type 1 diabetes mellitus (T1DM) presenting with diabetic ketoacidosis (DKA) in a tertiary care center in the Western region of Saudi Arabia.

METHODS

We retrospectively reviewed 147 children and adolescents diagnosed with T1DM who presented with DKAs between January 2019 and December 2023. Data on age, gender, nationality, economic status, episode severity, presenting symptoms, and biochemical markers were collected and analyzed.

RESULTS

The mean patient age was 7.24 years, with known patients being older (mean age: 8.24 years) than newly diagnosed patients (mean age: 6.34 years). Most patients (55.8%) belonged to the middle-childhood age group (6 to 11 years). Among known patients, the most prevalent symptoms included vomiting, reported by 62 (88.6%) individuals, and abdominal pain, which affected 55 (78.6%). In contrast, new patients exhibited a strikingly high incidence of polyuria, with 68 (88.3%) cases, and polydipsia, affecting 65 (84.4%) individuals.

CONCLUSION

The DKA incidence was higher in newly diagnosed patients, particularly in the middle-childhood age group. Economic factors may contribute to disease manifestations, and newly diagnosed patients had longer DKA symptom durations. The higher DKA incidence and severity in newly diagnosed patients, particularly in certain age groups, underscores the importance of increased disease awareness and early diagnosis.

The role of ACPs in recognising and treating diabetic ketoacidosis and hyperosmolar hyperglycaemic state

Diabetic ketoacidosis (DKA) and hyperosmolar hyperglycaemic state (HHS) are both diabetic emergencies that require immediate identification and intervention. Advanced clinical practitioners (ACPs) play a crucial role in the early detection, management and co-ordination of care for patients with these conditions, although some may feel less confident in handling such complex cases. This clinical review explores the role of ACPs in managing DKA and HHS, focusing on their responsibilities in diagnosis, treatment initiation, and communication within multidisciplinary teams. It also examines the epidemiology, pathogenesis, risk factors, and causes of these conditions, alongside diagnostic criteria and management strategies. In addition, the review highlights the importance of minimising risks and preventing recurrence to ultimately enhance patient outcomes.

Diagnostic Biomarkers of Microvascular Complications in Children and Adolescents with Type 1 Diabetes Mellitus-An Updated Review

Type 1 diabetes mellitus (T1DM) is regarded as the most chronic autoimmune disease affecting children and adolescents that results from a destruction of pancreatic β-cell and leads to insulin insufficiency and persistent hyperglycemia (HG). Children and adolescents with T1DM are at an increased risk of developing microvascular complications, including diabetic nephropathy (DNE), diabetic retinopathy (DR), and diabetic neuropathy (DNU). The risk factors and prevalence of these complications differ greatly in pediatric studies. Screening for T1DM microvascular complications undergoes different stages and it is recommended to identify early symptoms and clinical signs. The identification of biomarkers in T1DM microvascular complications is needed to provide optimal treatment. Despite several studies on early biomarkers for DNE in children, the potential biomarkers for predicting DR and DNU have not been completely illustrated. This review fills this gap by identifying biomarkers of T1DM microvascular complications in children and adolescents through searches in the PubMed/Medline database.

Patterns and Characteristics of Diabetic Ketoacidosis in Children With Type I Diabetes in Saudi Arabia

BACKGROUND

Type 1 diabetes mellitus (T1DM) in children, a significant public health concern, often leads to diabetic ketoacidosis (DKA). The prevalence of T1DM is increasing globally, with Saudi Arabia recording high rates of DKA at T1DM onset. This study aimed to evaluate the characteristics and risk factors of pediatric T1DM patients presenting with DKA in the emergency room in Saudi Arabia and quantify intensive care unit (ICU) admission incidences reflecting DKA severity.

METHODS

This retrospective chart review, conducted at Medina Maternity and Children's Hospital, Saudi Arabia, analyzed data from 2017 to 2022. The study included children and adolescents under 18 presenting with DKA, using non-probability consecutive sampling. Patient medical records provided demographic, medical, and laboratory data, and the analysis employed SPSS for statistical assessment.

RESULTS

The study enrolled 70 participants, predominantly female (n = 42, 60%) and Saudi nationals (n = 63, 90%). The average age at diabetes mellitus (DM) onset was 6.9 years, with a mean hospital stay of 3.31 days. About 18.57% (n = 13) were newly diagnosed with DM, and 81.43% (n = 57) were known cases of DM. Most participants (n = 59, 86.8%) had no comorbidities, while 7.4% (n = 5) had celiac disease. The recovery rate was high (n = 67, 95.7%), with 80% (n = 56) experiencing no complications. Notably, 44.3% (n = 31) were admitted to a ward, and 12.9% (n = 9) required ICU admission. Weight was found to be a significant predictor of ICU admission (OR = 1.26, 95% CI: 1.05 to 1.5; p = 0.011).

CONCLUSIONS

This study highlights the importance of personalized insulin therapy and weight management in pediatric T1DM patients presenting with DKA. It suggests that early and effective management in emergency settings can significantly improve patient outcomes. The study also calls for further research into long-term management strategies and the impact of targeted educational programs.
