6674 Non-Progressive Diabetes Leading to Neurologic Diagnosis

Abstract Disclosure: F.L. Thelmo: None. M. Murugesh: None. B. Simon: None. Introduction: The autoantibody GAD (anti-glutamic acid decarboxylase) is highly associated with Type 1 diabetes (T1DM) and Latent Autoimmune Diabetes in Adulthood (LADA). If GAD is detected before the onset of overt diabetes, typically 80% of patients with abnormal glucose tolerance progress to insulin deficiency and the need for insulin treatment after 5 years.[1] Stiff Person Syndrome (SPS) is also associated with GAD antibodies, but in SPS, the GAD antibodies are believed to be different epitopes that target GABA production in neuromuscular pathways. We present a case of presumed LADA that did not progress for 30 years, with progressive neurologic symptoms leading to a diagnosis of SPS in later adulthood.Case: A 52-year-old female presented for evaluation of T1DM and worsening neuropathies. She had a long history of prediabetes, with mildly elevated glucose values noted on labs since her early twenties. There was no family history of T1DM or autoimmune conditions. Six years ago, she sought endocrine evaluation. HgbA1c values were 6.1 to 6.6%. Intermittent use of continuous glucose monitoring (CGM) revealed post-prandial hyperglycemia up to 180mg/dL, occasionally (but rarely) exceeding 200mg/dL. She recalls being told that she had positive antibodies (unclear which ones tested) and given a diagnosis of T1DM. She declined insulin and maintained glycemic control with carbohydrate restriction and exercise; there were no episodes of diabetic ketoacidosis. She then developed neurologic symptoms: fullness, tightness and bloating in the abdomen (diagnosed with gastroparesis on scanning) and after a COVID 19 booster in 2021, muscle spasms in the legs and back with worsening abdominal tightness. At the time of her current presentation, A1C was 6.4%, glycated albumin was 14.4% (prediabetes range 13.6 - 15.5%) and CGM time in range was 99%. A non-fasting C-peptide was 3.6 ng/mL (1.1- 4.4ng/mL) with glucose of 119 mg/dL. Repeat antibody testing revealed undetectable IA-2 and ZnT8 antibodies, but GAD was grossly elevated at 1,015.3 U/mL. Given the unusually high GAD titer, SPS was suspected, and this diagnosis was confirmed on referral to neurology. The patient was advised to liberalize diet and will be monitored with HgbA1c and serial C-peptide levels to assess progression in the future. Discussion: While high GAD antibody levels are associated with progression to insulin dependence in adults with LADA, in SPS the GAD titers tend to be even higher2. The presence of only one auto-antibody for T1DM (and not multiple), long-standing non-progressive hyperglycemia, and normal C-peptide pointed away from autoimmune diabetes being the etiology for mild glucose intolerance in this patient. If neurologic symptoms are present, high GAD should prompt the evaluation for other syndromes associated with GAD antibody epitopes such as SPS. Presentation: 6/2/2024

6660 Euglycemic DKA Induced by SGLT-2 Inhibitor Following Administration ofTirzepatide

Abstract Disclosure: K. Gurel: None. S. Mathew: None. M. Zeidan: None. S. Al Barznji: None. F. Alkhankan: None. Introduction Tirzepatide has side effects of diarrhea, nausea, vomiting, and loss of appetite(2). SGLT-2 inhibitors may cause Euglycemic Diabetic ketoacidosis(EDKA) by inducing carbohydrate starvation and volume depletion(1). Clinical Case A 72-year-old male with a past medical history of T2DM(Hg A1c 8.4[≤ 6%]) on empagliflozin, metformin, hyperlipidemia, obesity on tirzepatide who presents with complaining of nausea, vomiting, and abdominal pain. The patient noted that he started experiencing symptoms two days before admission following receiving tirzepatide dose. He takes Tirzepatide every 10 days and he was started on empagliflozin 1 month ago. The patient started to have a loss of appetite, nausea, and vomiting on the day he received his tirzepatide injection. Over the next two days, the patient’s nausea and vomiting worsened and the patient was not able to tolerate food. On admission, ABG demonstrated pure metabolic acidosis (pH of 7.24[7.30-7.40], bicarb of 11.8 [21 - 28 mmol/L] PCO2 of 27.4[ 41 - 51 mmHg]). BMP showed anion gap of 20(3-15 mmol/L) with glucose level of 145(74-106 mg/dl) . Beta-Hydroxybutyrate level was 6.3(0.0 -0.27 mmol/L). UA was only significant for glucose level of >1000(negative) and ketone level of 40(negative). Lipase level was 539(73-393 U/L). CT abdomen ruled out acute pancreatitis. No infection source was identified. Upon admission to the ICU unit, the patient was started on D5 with KCL 20 mEq and Insulin drip. The patient was followed up with a glucose check every hour and BMP every 4 hours. On day 2 of admission, the Anion gap was normalized and the insulin regimen was transitioned to subcutaneous insulin. The patient was placed on carbohydrate consistent diet. On discharge, the patient was advised to avoid taking SGLT-2 inhibitors including empagliflozin. Conclusion Tirzepatide's potential side effects, including diarrhea, vomiting, and appetite loss, may contribute to volume depletion and carbohydrate starvation(2). Individuals using both SGLT-2 inhibitors and Tirzepatide should be closely monitored for these symptoms. Reference 1-)Baggio LL, Drucker DJ.

12620 Developing Hospital Protocols For Managing Patients With Hypertriglyceridemia-induced Acute Pancreatitis In Diabetic Ketoacidosis Hospitalizations

Abstract Disclosure: U. Agbedia-ejughemre: None. Methods: We queried the combined 2017-2020 nationwide inpatient sample database for all adult hospitalizations for DKA with and without HTG-AP using the ICD-10 revision codes. Baseline characteristics were compared between DKA hospitalizations with and without HTG-AP using Pearson’s χ2 tests and Student’s t-test for categorical and continuous variables. Study endpoints were the incidence, predictors, and outcomes of HTG-AP, including mortality, hospitalization duration, mean hospital costs, and acute in-hospital complications (sepsis, ARDS, and acute renal failure). Predictors of HTG-AP were assessed using stepwise multivariable logistic regression analysis. Illness severity, baseline risk of mortality, and comorbidity burden were adjusted using APR-DRG metrics and CCI. Prolonged hospitalization was defined as the length of hospital stay in the top decile of hospital stay for all hospitalizations in the study. Results: We analyzed 630,435 hospitalizations for DKA. The study cohort was 51.4% male, 57.6% white Americans and 26.1% Blacks, with a mean age of 40 (SD, 16.2) years. Incidence of HTG-AP was 2.1% (13,445). Hospitalizations with HTG-AP were older (mean age: 44 vs. 40 years; P<0.001) and had greater comorbidity (CCI score of 2: 38.7 vs. 33.8; P<0.001) compared with DKA hospitalizations without HTG-AP. While DKA hospitalizations showed an uptrend, increasing from 105,769 to 199,429 hospitalizations (Average annual percent change [AAPC]: 27.04%; P=0.029), the incidence of HTG-AP showed a downtrend from 2650 (2.5%) to 4085 (2.0%) (P=0.006). Predictors of HTG-AP included Hispanic (aOR: 2.45; 95% CI: 1.95-3.07; P<0.001) or Asian race (aOR: 2.48; 95% CI: 1.37-4.48; P=0.003), private insurance (aOR: 1.57; 95% CI: 1.10-2.25; P=0.013), self-pay (aOR: 2.2; 95% CI: 1.49-3.27; P<0.001), APR-DRG moderate risk of mortality (aOR: 1.52; 1.21-1.92; P<0.001), APR-DRG major loss of function (aOR: 1.46; 95% CI: 1.31-1.69; P<0.001), dyslipidemia (aOR: 1.87; 95% CI: 1.47-2.38; P<0.001), hypertension (aOR: 1.39; 95% CI: 1.13-1.72; P=0.002), obesity (aOR: 3.09; 95% CI: 2.42-3.96; P<0.001), obstructive sleep apnea (aOR: 2.05; 95% CI: 1.35-3.10; P=0.001), chronic liver disease (aOR: 9.44; 95% CI: 6.61-13.48; P<0.001), old MI (aOR: 2.11; 95% CI: 1.02-4.38; P=0.045), and COPD (aOR: 2.31; 95% CI: 1.47-3.64; P<0.001). DKA hospitalizations with HTG-AP were correlated with higher risk of septicemia (aOR: 1.20; 95% CI: 1.05-1.69; P=0.029), ARDS (aOR: 1.24; 95% CI; 1.04-2.07; P=0.004), and resource use, including prolonged hospitalization (26.3% vs. 11.1%; P<0.001), and higher mean hospital costs ($57,773 vs. $32,692; P<0.001). Conclusion: HTG-AP was linked to worse outcomes, excluding mortality, in hospital admissions for DKA. There is a need for enhanced diagnostic guidelines and protocols targeting this subgroup of patients could improve outcomes. Presentation: 6/2/2024

8075 Euglycemic Diabetic Ketoacidosis Associated With Cocaine Use

Abstract Disclosure: N.N. Solanki: None. A.N. Kiani: None. M. Feldman: None. Euglycemic diabetic ketoacidosis (EDKA) is characterized by increased anion gap metabolic acidosis, ketonemia or ketonuria, and normal blood glucose levels (<200 mg/dL). Due to the absence of hyperglycemia, it commonly presents as a diagnostic and therapeutic dilemma. EDKA is commonly associated with decreased caloric intake, sodium-glucose cotransporter-2 (SGLT-2) inhibitors, recent use of insulin, heavy alcohol consumption, chronic liver disease, glycogen storage disorders, and drug-induced intoxication. Cocaine use is a lesser-known etiology for EDKA. We present a case of a 64-year-old female with a history of type 2 diabetes mellitus who presented with complaints of decreased oral intake for two days secondary to nausea and vomiting and productive cough for one week, along with cocaine use. Despite an extensive history of diabetes and no recent SGLT-2 inhibitor use, her labs were consistent with euglycemic DKA. Her imaging and further investigations revealed respiratory syncytial virus pneumonia. The patient was initially managed for starvation ketoacidosis with fluid resuscitation with no improvement in acidosis and later treated with DKA protocol with rapid correction of her anion gap metabolic acidosis. This case highlights the challenges associated with diagnosing and treating EDKA. Early initiation of DKA protocol should be considered in diabetic patients presenting with euglycemia with high anion gap metabolic acidosis with a clinical picture of starvation and cocaine use.

8197 A Captivating Case Report of Teprotumumab Induced Hyperglycemic Hyperosmolar State

Abstract Disclosure: K.M. Tuna: None. J.P. Perdomo Rodriguez: None. Introduction: Teprotumumab, a monoclonal antibody targeting the IGF-1 receptor, is increasingly utilized for moderate to severe thyroid eye disease. Initial trials noted mild hyperglycemia in patients with diabetes, while recent trials revealed a significant elevation in Hemoglobin A1c (HbA1c) among those with diabetes or pre-diabetes post-infusion. Here, we discuss a case of a patient with diet-controlled diabetes who developed hyperglycemic hyperosmolar state (HHS) two months after Teprotumumab infusion. Case Presentation: A 43-year-old male, with class III obesity, obstructive sleep apnea, dyslipidemia, coronary artery disease, and diet-controlled diabetes (HbA1c 6.5%) presented with worsening proptosis, decreased color vision, severe visual field depression. Laboratory evaluation revealed elevated TSH (6.3 mIU/ml), normal free T4 (0.67 ng/dl, ref: 0.60-1.2 ng/dl), and undetectable Thyroid Stimulating Immunoglobulin (<0.1 IU/L). Blood cell count, renal and liver function tests were normal. Due to high clinical suspicion of thyroid eye disease, he was treated with timolol, dorzolamide, brimonidine, and methylprednisolone 1g daily for 3 days. Glycemic control was achieved with 30 units of daily insulin while on pulse steroids. On outpatient ophthalmology follow-up, Teprotumumab was initiated and he received 2 doses. Eight weeks later, the patient was hospitalized with altered mental status caused by HHS (glucose 617 mg/dl, serum osmolality 316 osm). HbA1c was found to be significantly increased to 12% and the patient required 150 units total daily insulin and metformin upon discharge. Of note, the patient did not have significant weight changes during this time. GAD, IA2, and Zinc Transporter-8 antibodies were obtained prior to discharge and results are pending. Discussion: The IGF-1 receptor, a partial homologue of the insulin receptor, plays a pivotal role in glucose homeostasis. Inhibiting this receptor can lead to hyperglycemia. Initial randomized controlled trials (RCTs) reported a 10% incidence of mild hyperglycemia. A recent RCT from a cohort of 42 patients demonstrated a 50% incidence of hyperglycemia, in which two-thirds of the patients remained in a dysglycemic state with one patient with pre-existing prediabetes developing diabetic ketoacidosis (DKA). Our patient mirrored this scenario with no identifiable confounding factors. Conclusion: Teprotumumab-induced hyperglycemia, though rare, can lead to life-threatening complications. Baseline glycemic assessment, identification of high-risk patients, and comprehensive discussions on risks and benefits are crucial before initiating therapy. Close monitoring, especially in those with prediabetes, is recommended. Patient education plays a pivotal role in early symptom recognition, averting delayed diagnoses, and subsequent hospitalization. Presentation: 6/3/2024

Characteristics and Treatment Outcome of Pediatric Diabetic Ketoacidosis in Mekong Delta, Vietnam: A 5-Year Retrospective Study

Background Diabetic ketoacidosis (DKA), a critical and potentially fatal complication resulting from a lack of insulin, presents with elevated blood sugar, acid-base imbalance, and increased ketone bodies. Objectives Our research was designed to assess the clinical manifestations, laboratory findings, and outcomes of treatment in children diagnosed with DKA over a span of five years in the Mekong Delta region of Vietnam. Methods This study retrospectively analyzed pediatric cases of diabetic ketoacidosis treated at a major pediatric center in the Mekong Delta between 2017 and 2021. Results Diabetic ketoacidosis was more common in older children aged 11 – 16 years (66.7%), and females (70%). The majority of cases had not been diagnosed with previous diabetes (60%) and no history of diabetic ketoacidosis (90%). In univariate analysis, female gender (OR, 13.0; 95% CI, 1.4 – 124.3; p=0.026), previous diabetes diagnosis (OR, 7.8; 95% CI, 1.5 – 41.2; p=0.016), precipitating factors (OR, 10.1; 95% CI, 1.1 – 97.0; p=0.045), tachypnea (OR, 5.5; 95% CI, 1.1 – 26.4; p=0.033), Kussmaul breathing (OR, 5.4; 95% CI, 1.1 – 26.0; p=0.036), serum potassium level (OR, 3.5; 95% CI, 1.2 – 10.4; p=0.027), and anion gap (OR, 1.6; 95% CI, 1.8 – 2.3; p=0.003) were associated factors with severe DKA. All cases in our study had a 100% survival rate. Anion gap was an independent factor associated with severe diabetic ketoacidosis after adjustment multivariate analysis. Conclusion: Female, younger age, precipitating factors, tachypnea, Kussmaul’s breathing, and relevant laboratory findings, including increased anion gap, should be considered to ensure successful management in pediatric diabetic ketoacidosis.

A-051 Validation and Implementation of the Stanbio Beta-Hydroxybutyrate Assay on Roche c502 Analyzer

Abstract Background β-hydroxybutyrate (βOHB) serves as a crucial biomarker in assessing, managing, and monitoring ketosis in various clinical scenarios, such as diabetic ketoacidosis and instances of alcohol abuse combined with starvation. This study aimed to validate a βOHB assay (Stanbio Laboratory) conducted on a Roche Cobas c502 analyzer and establish performance specifications. Additionally, we conducted a method comparison for three assays: Randox D-3-Hydroxybutyrate (Ranbut) assay on Roche c501 analyzer, Abbott Freestyle Precision B-Ketone strip point-of-care test, and the Stanbio Laboratory β-Hydroxybutyrate LiquiColor assay on Roche c502 analyzer. Methods Precision, linearity, limit of quantification (LOQ), method comparison, and sample stability were determined according to Clinical and Laboratory Standards Institute (CLSI) guidelines, using commercial quality control materials (Randox Multisera) and residual patient samples (Lithium heparin anti-coagulated plasma). The reference interval was verified by residual samples from 20 healthy individuals (normal blood glucose, HbA1c, liver enzymes, and lipid panel results). Statistical analysis was performed by EP-Evaluator (v12). Results Intra-assay and total coefficient of variation (CV) were determined as 0% and 2.4% at 0.3 and 1.21 mmol/L, respectively. The linearity range of the assay was verified from 0.0 to 9.0 mmol/L. Using CV < 20% as criteria, the functional sensitivity (LOQ) was 0.10 mmol/L at least. Lithium heparin anti-coagulated plasma specimens were stable for 24 hours at room temperature or seven days at 4 - 8 ̊C. The manufacturer’s reference interval was verified as 0.00 - 0.40 mmol/L. The Stanbio βOHB assay on the Roche c502 analyzer demonstrated a strong agreement with the Randox D-3-Hydroxybutyrate assay on the Roche c501 analyzer with a slope of 1.053 (95% CI: 1.037, 1.070) and intercept of -0.005 (95% CI: -0.068, 0.059) (coefficient correlation R = 0.9992). A positive bias was observed compared to the Abbott Freestyle Precision B-Ketone strip POC test (mean bias = + 0.50 mmol/L; slope = 1.630, 95% CI: 1.404, 1.857; R = 0.9184), and this discrepancy occurred particularly at βOHB > 5.5 mmol/L measured by Abbott method. Conclusions The Standbio βOHB assay exhibited excellent precision and linearity across a brand range of concentrations. This assay strongly agrees with the Randox assay run on a similar instrument but discordance with Abbott’s POCT method at high βOHB concentration. Overall, the validated method provides a reliable and efficient means for measuring βOHB levels on a Roche chemistry analyzer, facilitating accurate diagnosis and monitoring of ketosis-related conditions in clinical settings.

Comparison of the Volumetric Parameters of Platelets in Diabetic Children with and without Diabetic Ketoacidosis: A Case-Control Study in the North of Iran

Background: This study aimed to determine the volumetric parameters of platelets including MPV (Mean Platelet Volume) and PDW (Platelet Distribution Width) in diabetic children with and without diabetic ketoacidosis (DKA) and to evaluate their relationship with the severity of DKA. Materials and Methods: A case-control study was conducted on 112 children with type 1 diabetes mellitus (T1DM), with and without DKA, who referred to Amirkola Children's Hospital, Iran, in 2016-2021. Of them, 43 were boys, and 69 were girls. The diagnosis of diabetes was based on clinical symptoms and diagnostic criteria, and DKA was diagnosed through the analysis of arterial blood gas. The patients’ MPV and PDW were also evaluated, and the P values less than 0.05 were considered significant. Results: Out of 112 children with diabetes (with the mean age of 8.71 ± 3.22 years), 56 persons had DKA. In terms of DKA severity, 17 patients (30.4%) had mild, 29 (51.8%) had moderate, and 10 (17.8%) had severe DKA. The children with DKA had the mean blood glucose of 490.98±46.11mg/dL, MPV of 10.02± 1.19fl), and PDW of 13.07± 1.18flwere significantly higher (P<0.001). It was found that, an increase in the severity of DKA would raise the mean MPV (P = 0.006) and PDW(P<0.001) significantly. Conclusion: Based on the results of this study, as the severity of DKA increases in diabetic children, the mean levels of MPV and PDW increase significantly. Therefore, it is suggested that MPV and PDW be used to predict the severity of DKA in diabetic children.

Diabetic ketoacidosis as first presentation of undiagnosed pancreatic cancer in an octogenarian.

Diabetic ketoacidosis (DKA) is a complication of diabetes mellitus (DM) that can theoretically occur in people of any age. While DKA can typically be the first presentation of type 1 DM in younger people, a first presentation is rare in older adults. Pancreatic cancer often manifests with new DM or hyperglycaemia, but very rarely as DKA. We report a case of an 89-year-old woman who was incidentally diagnosed with DKA during workup for an unwitnessed fall. Her DKA was promptly managed, and she was subsequently diagnosed with metastatic pancreatic cancer. Given the advanced stage of her malignancy, the multidisciplinary team consensus was for a palliative approach. She passed away on day 10 of the admission. To our knowledge, this is the first report of a first DKA presentation as a manifestation of pancreatic cancer in an adult aged over 70 years. To date, there is no effective screening test for pancreatic cancer in the general population. However, new-onset DM in the appropriate context might indicate the need for further evaluation. While it is possible that unresectable tumours are identified, earlier diagnosis of DM with pancreatic cancer may facilitate more timely management, including earlier advanced care planning. A higher clinical suspicion for pancreatic cancer is required for older adults presenting with diabetic ketoacidosis without a previously diagnosed diabetes mellitus. A bi-directional relationship exists between diabetes and pancreatic cancer. Pancreatic cancer generally has a very poor prognosis due to its advanced stage at diagnosis and the lack of an effective screening test. New-onset diabetes in the appropriate context (such as weight loss) can indicate the need for further evaluation for underlying pancreatic cancer.

Factors associated with severe diabetic ketoacidosis in patients diagnosed with type 1 diabetes: a decade-long cross-sectional analysis.

The aim of this study was to identify factors associated with severe diabetic ketoacidosis (DKA) at the onset of type 1 diabetes mellitus (T1DM) in adult patients. We conducted a retrospective analysis over a 10-year period including adults newly diagnosed with T1DM. Eligible participants were diagnosed with DKA at the time of T1DM diagnosis. DKA severity was categorized as mild, moderate, or severe. Data were collected on age, body mass index, family history of diabetes and autoimmune disorders, lifestyle habits, delayed diagnosis, and preceding factors. A total of 305 participants (69.8% men) with T1DM were included. Overall, 63 patients were admitted with severe DKA (Group 1) and 242 with non-severe DKA (Group 2). Factors associated with severe DKA at diagnosis of T1DM were a long period between symptom onset and first hospitalization, preceding infection, tachypnea, thrombocytopenia, anemia, hepatic cytolysis, polyuria, and tachycardia. The present findings highlight the need for improving awareness about diabetes symptoms among physicians and the public to reduce the occurrence and severity of DKA at the onset of T1DM.

Sudden visual loss after COVID-19 infection with diabetic ketoacidosis

We report a case of an atypical optic neuritis (AION) in an adolescent male, diagnosed with diabetic ketoacidosis in the setting of a coronavirus disease 2019 (COVID-19) infection. On the third day of admission, he developed sudden profound visual loss and ocular examination revealed bilateral pale disc edema. Examination and investigations were conclusive of bilateral optic neuritis. Optic neuritis in the setting of pale disc edema was unusual, and the pallor could be due to an episode of AION that was superadded by optic neuritis during the cytokine storm. The patient was given a trial of i.v. steroids. However, the vision loss could be recovered partially only. Thus, through this case report, we would like to highlight the importance of a close follow-up of patients following COVID-19 infection and a possible association of metabolic acidosis in precipitating the episode of optic neuritis.

Real-world efficacy and safety of open-source automated insulin delivery for people with type 1 diabetes mellitus: Experience from mainland China

BackgroundOpen-source automated insulin delivery systems are increasingly adopted yet predominantly discussed outside of Asia. This study aimed to describe efficacy and safety of android artificial pancreas (AAPS) in people with type 1 diabetes mellitus (T1DM) from mainland China. MethodsThis real-world study recruited people who initiated AAPS for ≥ 3 months between 2019 and 2024. Key outcomes included glycated hemoglobin A1c (HbA1c) and metrics from continuous glucose monitoring, rates of diabetic ketoacidosis (DKA) and severe hypoglycemia. Findings292 (male, 46·9 %) participants aged 25·7 (14·7, 35·0) years were included, with 183 (62·7 %) and 68 (23·3 %) using AAPS for 6 and 12 months. Prior-AAPS HbA1c was 7·6 ± 1·7 % with 44·5 % achieving < 7·0 %. After 3 months, mean HbA1c improved by −1·5 ± 2·0 % to 6·3 ± 0·8 % (P < 0.01), with 82·9 % achieving < 7.0 %. Time in range 3·9-10·0 mmol/L (TIR) improved to 78·8 ± 12·9 %, with 80·5 % achieving > 70 %, followed by time below 3·9 mmol/L of 3·9 (2·1, 6·1) %. After 12 months, HbA1c and TIR remained similar at 6·4 ± 1·0 % and 77·9 ± 12·2 %. No DKA and severe hypoglycemia was observed. InterpretationReal-world data from mainland China highlights current uptake of open-source AAPS with potential glycemic benefits. No safety signals are seen. More support to enhance access and utilization of all AID systems in this region is warranted.

Hospital-acquired venous thromboembolism among critically ill children with diabetic ketoacidosis: a multicenter, retrospective cohort study

BackgroundCritically ill children and young adults with diabetic ketoacidosis are thought to be in a prothrombotic state. However, the rate of hospital-acquired venous thromboembolism and associated risk factors in this population have not been identified. ObjectivesChildren hospitalized for diabetic ketoacidosis (DKA) may be at increased risk of hospital-acquired venous thromboembolism (HA-VTE). We sought to estimate the incidence of HA-VTE and identify unique prothrombotic risk factors in this population. MethodsWe performed a multicenter, retrospective cohort study using the Pediatric Health Information Systems registry including patients aged 0 to 21 years hospitalized for DKA from January 2017 to December 2023 within 48 participating centers. The primary outcome was the frequency of HA-VTE. Secondary outcomes were rates of cerebral edema, central venous catheterization (CVC), invasive mechanical ventilation (IMV), infection, and length of stay (LOS). An adjusted logistic regression was employed to identify potential HA-VTE risk factors. ResultsOf the 27,613 patients studied, 93 (0.3%) developed a HA-VTE. Compared with those without HA-VTE, those with HA-VTE had a greater median LOS (10 [IQR, 5-21] vs 2 [IQR, 2-3] days) and rates of cerebral edema (25.8% vs 6.6%), CVC (23.7% vs 1.1%), infection (72% vs 23.5%), and IMV (39.8% vs 1.4%; all P < .001). In an adjusted logistic model, factors independently associated with increased HA-VTE were CVC (adjusted odds ratio [aOR], 3.04; 95% CI, 1.49-6.19), infection (aOR, 4.61; 95% CI, 2.81-7.56), IMV (aOR, 9.24; 95% CI, 4.83-17.56), and increasing LOS (aOR, 1.05; 95% CI, 1.02-1.06; all P < .01). ConclusionThe frequency of HA-VTE among critically ill children and young adults hospitalized for DKA was 0.3%. After prospective validation, putative risk factors (ie, CVC, IMV, infection, and extended LOS) may be incorporated into the design of forthcoming pediatric thromboprophylaxis trials.

Etiopatogenia y situación epidemiológica de la diabetes mellitus tipo 1

Type 1 diabetes mellitus (DM1) accounts for 5%-10% of diabetes cases worldwide. In most patients, the pathogenesis is the autoimmune destruction of pancreatic beta cells; in a small percentage, the origin is idiopathic. Although its onset is more common in children, it can also appear in adults, in whom the course is usually slower. Three phases or stages of DM1 have been defined. Virtually all patients with two or more antibodies will develop clinical DM1 (stage 3). In regard to DM1 prevention, there are multiple therapies under study that are aimed at halting the immunologic process or preserving the beta cell. Only teplizumab has been approved by the FDA in stage 2 DM1. The typical clinical symptoms in the diagnosis of DM1 is diabetic ketoacidosis (DKA), which is considered a medical emergency that requires the administration of insulin for its resolution. The determination of autoantibodies in relatives of patients with DM1 has increased the detection of cases of preclinical or asymptomatic DM1 and the need for universal screening for DM1 is being proposed.

A Unique Government–NGO–Industry Partnership Care Model to Reduce Morbidity and Mortality Among Underprivileged Children With Type 1 Diabetes Mellitus in LMIC: A Pilot Study From Tamil Nadu, India

Abstract Aim: To pilot a 1-year comprehensive type 1 diabetes mellitus program, assessing outcomes on glycemic control and diabetic ketoacidosis (DKA) admissions pre- and post-intervention in underprivileged children with type 1 diabetes mellitus from three selected Government Medical College Hospitals across Tamil Nadu state, through a Government–nongovernmental organization (NGO)–Industry partnership. Materials and Methods: A total of 214 children were identified through the hospital database. Highly focused diabetes mellitus and insulin education along with analog insulins in penfill cartridges in the basal-bolus regime, high quality 800 memory glucometers with 100 glucose strips per month, ultrafine needles, 24/7 telephone support, and monthly review were supported to all the children. Data on baseline characteristics, pre- and post-intervention glycosylated hemoglobin A1c (HbA1c), and DKA admissions were tabulated on Microsoft Excel, and the results were analyzed. Results: A 2.4% reduction in HbA1c and more than 90% reductions in DKA admissions were seen post-intervention compared with baseline. This can potentially translate to huge reductions in mortality and cost savings for all stakeholders. Conclusions: A combined Government–NGO–Industry partnership is the need of the hour to reduce morbidity and mortality associated with type 1 diabetes mellitus among underprivileged children in India. Our model has the potential to serve as a blueprint for type 1 diabetes mellitus care in low- and middle-income countries.

Protocolo terapéutico y seguimiento del paciente con diabetes mellitus tipo 1 y obesidad

Treatment protocol and follow-up of patients with type 1 diabetes and obesity This protocol focuses on the management of obesity in patients with type 1 diabetes mellitus (DM1), a growing problem due to factors such as lifestyle, insulin treatment, and hypoglycemia. The approach includes four key pillars: nutrition therapy, drug therapy, physical activity, and management of insulin therapy. Nutrition therapy is the first line of treatment and is based on calorie reduction and a diet rich in fiber. In addition, there are pharmacological options for the management of overweight in patients with DM1, although they have specific challenges, such as euglycemic diabetic ketoacidosis. Physical activity and the adjustment of insulin therapy also play an essential role in weight and glycemic control. In severe cases, bariatric surgery is a viable option for patients with severe obesity.
