Project description:ObjectivePrevious studies show that vasogenic cerebral edema (CE) occurs during diabetic ketoacidosis (DKA) treatment in children, but the role of intravenous fluids in contributing to CE is unclear. We used magnetic resonance diffusion weighted imaging to quantify subclinical CE in children with DKA randomized to 2 intravenous fluid regimens.MethodsChildren with DKA were randomized to receive fluids at a more rapid rate (n = 8) or a slower rate (n = 10), with all other aspects of DKA treatment kept identical. Children underwent diffusion weighted imaging 3 to 6 hours and 9 to 12 hours after beginning DKA treatment and after recovery from DKA (≥ 72 hours after beginning treatment). We calculated brain apparent diffusion coefficient (ADC) values as the average of measurements in the basal ganglia, thalamus, frontal white matter, and hippocampus and determined the mean brain ADC value during DKA treatment by averaging data from the 3- to 6-hour and 9- to 12-hour measurements. The difference in mean brain ADC between DKA treatment and postrecovery was used as an index of the severity of CE during DKA treatment.ResultsMean brain ADC values during DKA treatment were significantly higher than postrecovery values, consistent with vasogenic CE (842 ± 38 vs 800 ± 41 × 10(-6) mm(2)/second, P = .002). We did not detect significant differences in ADC elevation in children treated with more rapid versus slower rehydration (β coefficient 0.11 for 1 SD change in ADC, 95% confidence interval: -0.91 to 1.13).ConclusionsADC changes during DKA treatment (reflective of vasogenic CE) do not appear to be substantially affected by the rate of intravenous fluid administration.
Project description:BackgroundThe second-generation antipsychotics (SGAs) are associated with metabolic disturbances. Diabetic ketoacidosis (DKA) is a rare, but potentially fatal sign of acute glucose metabolism dysregulation, which may be associated with the use of SGAs. This study aims to review published reports of patients with schizophrenia and antipsychotic drug-associated DKA, focusing on the effective management of both conditions.MethodsUsing a predefined search strategy, we searched PubMed and EMBASE from their inception to July 2016. The search terms were related to "diabetic ketoacidosis" and "antipsychotic medication." Case reports, case series, and reviews of case series written in English language were included in the review.ResultsSixty-five reports were analyzed. In most patients who developed antipsychotic-associated DKA, 1 or more suspected antipsychotic medications were discontinued. In 5 cases, a rechallenge test was trialed, and in only 1 case, it resulted in the elevation of blood glucose. The majority was subsequently treated with a different SGA in combination with insulin/oral hypoglycemic agents; although approximately a third of patients had a complete resolution of symptoms or could control diabetes with diet only at the point of discharge.ConclusionsPatients taking antipsychotic medications should be regularly screened for insulin resistance and educated about potential complications of antipsychotic medications. This will allow clinicians to individualize treatment decisions and reduce iatrogenic contribution to morbidity and mortality. To achieve best treatment outcomes, antipsychotic-induced DKA should be treated jointly by psychiatry and endocrinology teams.
Project description:Cerebral edema is a devastating complication of DKA which is extremely rare in adults but is the leading cause of diabetes-related death in the pediatric population. Newly diagnosed diabetes, younger age, first episode of DKA, severity of DKA at presentation, and administration of bicarbonate are predictive of cerebral edema in DKA. We present a case of a young adult with DKA as the presenting symptom of diabetes, whose clinical course was complicated by renal failure, refractory shock, and cerebral edema. This case addresses the controversy surrounding bicarbonate therapy in DKA and its possible role in the development of a rare fatal complication of DKA.
Project description:Alpelisib is a phosphoinositol-3-kinase alpha catalytic subunit (PIK3CA) inhibitor used in patients with PIK3CA mutated breast cancer. The phosphatidylinositol 3-kinase (PI3K) pathway is responsible for activating protein kinase-B (AKT), and activated AKT promotes translation of glucose transporter 4 and glycogen synthesis in insulin-responsive tissues. Therefore, it is perhaps not surprising that hyperglycemia is the most common side effect of alpelisib, though diabetic ketoacidosis (DKA) appears to be a rare complication. This case describes the unique presentation of a patient with no prior history of diabetes who presented with DKA after starting alpelisib, and returned to euglycemia off of insulin just three days after stopping the drug suggesting that alpelisib can cause DKA in patients who did not previously have diabetes, and that the hyperglycemia is completely reversible upon discontinuation of the PIK3CA inhibitor and consequent restoration of the PI3K/AKT pathway.
Project description:ObjectivesTo characterize hemodynamic alterations occurring during diabetic ketoacidosis (DKA) in a large cohort of children and to identify clinical and biochemical factors associated with hypertension.Study designThis was a planned secondary analysis of data from the Pediatric Emergency Care Applied Research Network Fluid Therapies Under Investigation in DKA Study, a randomized clinical trial of fluid resuscitation protocols for children in DKA. Hemodynamic data (heart rate, blood pressure) from children with DKA were assessed in comparison with normal values for age and sex. Multivariable statistical modeling was used to explore clinical and laboratory predictors of hypertension.ResultsAmong 1258 DKA episodes, hypertension was documented at presentation in 154 (12.2%) and developed during DKA treatment in an additional 196 (15.6%), resulting in a total of 350 DKA episodes (27.8%) in which hypertension occurred at some time. Factors associated with hypertension at presentation included more severe acidosis, (lower pH and lower pCO2), and stage 2 or 3 acute kidney injury. More severe acidosis and lower Glasgow Coma Scale scores were associated with hypertension occurring at any time during DKA treatment.ConclusionsDespite dehydration, hypertension occurs in a substantial number of children with DKA. Factors associated with hypertension include greater severity of acidosis, lower pCO2, and lower Glasgow Coma Scale scores during DKA treatment, suggesting that hypertension might be centrally mediated.
Project description:Background/objectiveThe prevalence of diabetic ketoacidosis (DKA) in gestational diabetes mellitus (GDM) is very low. We describe a patient with GDM in whom severe DKA with intrauterine fetal demise developed in the setting of nonadherence to therapy.Case reportA 33-year-old woman, G2P0010, with no preexisting diabetes mellitus (DM) presented at 30 weeks of gestation with acute-onset altered sensorium, nausea, and emesis. GDM was diagnosed at 15 weeks of gestation with a serum glucose level of 266 mg/dL (70-134 mg/dL) after 1-hour 50-gram glucose challenge test. Glycated hemoglobin (HbA1C) was 5.9% (41 mmol/mol) at the time of GMD diagnosis. Insulin was initiated at week 20 of gestation. On presentation, serum glucose level of 920 mg/dL (70-110 mg/dL), pH of 7.02 (7.32-7.43), anion gap level of 38 mmol (5-17 mmol), bicarbonate level of 5.0 mEq/L (22-29 mEq/L), and large serum ketones were found. Ultrasound showed intrauterine fetal demise. She received intravenous fluids and continuous insulin. Following the spontaneous delivery of a nonviable fetus, DKA was resolved. Negative antiglutamic acid decarboxylase, islet cell, and zinc transporter 8 antibodies, C-peptide level of 2.4 ng/dL (1.1-4.4 ng/dL), and HbA1C level of 9% (75 mmol/mol) were found. Inpatient management included basal-bolus and sliding scale insulin therapies. Metformin was added upon discharge 7 days after admission. The HbA1C levels were 5.3% (34 mmol/mol) and 5% (31 mmol/mol) at the 3- and 6-month follow-ups, respectively. Insulin was discontinued. Currently, the patient is on metformin and glucagon-like peptide 1 receptor agonist.DiscussionThe development of insulin resistance during pregnancy is driven by multiple factors. Approximately 1% to 2% of pregnant women with impaired glucose tolerance develop DKA; most cases occur in women with type 1 DM. The approximate incidence of DKA in GDM is 0.02%.ConclusionDKA complicating GDM is extremely infrequent, but it cannot be dismissed. Early recognition along with prompt and appropriate medical and obstetrical management is critical.
Project description:ImportanceIntravenous (IV) insulin infusion is the standard of care for treating diabetic ketoacidosis (DKA) worldwide. Subcutaneous (SC) insulin aspart could decrease the use of health care resources.ObjectiveTo compare the cost-effectiveness of mild uncomplicated DKA management with SC insulin aspart vs IV insulin infusion among pediatric patients from the perspective of a public health care payer using clinical data.Design, setting, and participantsThis economic evaluation included children aged 2 to 14 years presenting to the emergency department of a single academic medical center with mild DKA between January 1, 2015, and March 15, 2020. The medical records for DKA treatment course and its associated hospitalization costs were reviewed. Data were analyzed from January 1, 2015, to March 15, 2020.ExposuresSubcutaneous insulin aspart vs IV regular insulin infusion.Main outcomes and measuresThe incremental cost-effectiveness ratio (US dollars per hour), duration of DKA treatment, and length of hospital stay.ResultsA total of 129 children with mild DKA episodes (mean [SD] age, 9.9 [3.1] years; 72 girls [55.8%]) were enrolled in the study. Seventy children received SC insulin aspart and 59 received IV regular insulin. Overall, the length of hospital stay in the SC insulin group was reduced (mean, 16.9 [95% CI, -31.0 to -2.9] hours) compared with the IV insulin group (P = .005). The mean (SD) cost of hospitalization in the SC insulin group (US $1071.99 [US $523.89]) was less than that in the IV insulin group (US $1648.90 [US $788.03]; P = .001). The incremental cost-effectiveness ratio was -34.08 (95% CI, -25.97 to -129.82) USD/h. The use of SC insulin aspart was associated with a lower likelihood of prolonged hospital stay (β = -17.22 [95% CI, -32.41 to -2.04]; P = .03) than IV regular insulin when controlling for age and sex.Conclusion and relevanceFindings of this economic evaluation suggest that SC insulin aspart is dominant vs IV regular insulin in the management of mild uncomplicated DKA in children.
Project description:The target audience of this simulation is emergency medicine residents and medical students. The simulation is based on a real case of a 12-year-old male who presented obtunded with shortness of breath and hypothermia who was ultimately diagnosed with diabetic ketoacidosis (DKA) and pneumomediastinum. This case highlights the diagnosis and management of an adolescent with new onset diabetic ketoacidosis and pneumomediastinum with deterioration of status, as well as important ventilator settings if intubation is required in the setting of diabetic ketoacidosis. Type 1 diabetes is a common disease in the pediatric population with the prevalence being approximately 2.15 per 1000 youths and diabetic ketoacidosis being the presenting status in 30-40% of the patients.1 Physicians who evaluate a child with altered mental status must have diabetic ketoacidosis in their differential. In the setting of mechanical ventilation in patients with diabetic ketoacidosis (DKA), special care must be taken. Mechanical ventilation in these patients comes with increased risk, morbidity, and mortality. Risk factors for pneumomediastinum include lung disease such as asthma, chronic obstructive pulmonary disease (COPD), and malignancy, but also can occur in the acute setting of vomiting or trauma.2. By the end of the simulation, learners will be able to: 1) develop a differential diagnosis for an adolescent who presents obtunded with shortness of breath; 2) discuss the management of diabetic ketoacidosis; 3) discuss management of hypothermia in a pediatric patient; 4) discuss appropriate ventilator settings in a patient with diabetic ketoacidosis; and 5) demonstrate interpersonal communication with family, nursing, and consultants during high stress situations. This is a high-fidelity simulation that allows learners to manage the diagnosis and treatment of diabetic ketoacidosis and hypothermia in an adolescent patient. Participants participated in a debriefing after the simulation. There should be approximately 4-5 learners per case. This simulation was performed in 3 sessions. Each learner performed this simulation one time. The effectiveness of this case was evaluated by surveys given to learners after debriefing. Learners gave quantitative and qualitative results of their feedback using a 1-5 rating scale and open-ended written questions. This case was trialed with residents in their first through third years of training as well as fourth year medical students. Feedback was very positive, with 19 residents completing the post-simulation survey. They enjoyed the case and reported they would feel more comfortable in a comparable situation in the future. Four survey questions were asked of the participants. On average, learners stated they felt the simulation improved their ability to manage a pediatric DKA patient, and their knowledge of complications and appropriate ventilator settings improved (modes of 5, 4 and 5, respectively). Diabetic ketoacidosis is a common and critical diagnosis for emergency medicine physicians to consider in the setting of altered mental status in a pediatric patient. This simulation has multiple steps and is based on a real case of an obtunded and hypothermic pediatric patient who was ultimately diagnosed with diabetic ketoacidosis complicated by pneumomediastinum.
