Background: Diabetic ketoacidosis (DKA) poses a significant medical emergency in both type 1 (T1DM) and type 2 diabetes mellitus (T2DM) patients. Recent attention has focused on the emergence of euglycemic DKA associated with sodium-glucose cotransporter-2 (SGLT2) inhibitors.

Objectives: To understand the epidemiology and outcomes of DKA, particularly in T2DM patients.

Methods: We conducted a retrospective cohort analysis of 204 patients admitted with DKA to Shamir Medical Center (2013–2021). We assessed demographics, clinical characteristics, and outcomes. Patients were stratified by diabetes type and SGLT2 inhibitor treatment status.

Results: Among the 204 patients with DKA, 38.2% had T2DM. Patients with T2DM exhibited older age, higher co-morbidity burden, and greater prevalence of microvascular complications compared to T1DM patients. Mortality rates were notably higher among T2DM patients, despite similar DKA severity at presentation, including in-hospital mortality rates of 6.4% vs. 0%, P < 0.05, and 90-day mortality rates of 7.7% vs. 0%, P < 0.05. T2DM was independently associated with adverse hospitalization outcomes, including a composite of rehospitalization, prolonged hospital stays, and mortality (odds ratio 2.68, 95% confidence interval 1.302–5.557). SGLT2 inhibitor treatment did not affect hospitalization outcomes of patients with T2DM.

Conclusions: Our findings underscore the importance of recognizing DKA as a substantial complication in diabetic patients, particularly those with T2DM. Vigilance in management, adherence to DKA guidelines, and awareness of triggers such as SGLT2 inhibitors are crucial for improving outcomes in this population.

Background: Diabetic ketoacidosis (DKA) is an acute metabolic, life-threatening complication of diabetes mellitus with a mortality rate that now stand at less than 1%. Although mortality is coupled with the etiology of DKA, literature on the influence of DKA etiology on patient outcome is scarce.

Objectives: To study different triggers for DKA and their effect on outcomes.

Methods: We conducted a retrospective study that include 385 DKA patients from 2004 to 2017. The study compared demographics, clinical presentation, and mortality rates by different precipitating factors.

Results: Patients with DKA due to infections had a higher risk to develop in-hospital mortality after controlling for age and sex (odds ratio 4.40, 95% confidence interval 1.35–14.30), had a higher Charlson Comorbidity Index score, a higher risk of being mechanical ventilated (14% vs. 3%, P < 0.01), and a longer duration of hospitalization (5 days vs. 3 days, P < 0.001).

Conclusions: It is crucial to find the triggers that precipitate DKA and start the treatment as early as possible in addition to the metabolic aspect of the treatment especially when the trigger is an infectious disease.

Background: Diabetic ketoacidosis (DKA) as the first presentation of type 1 diabetes mellitus (T1DM) is a serious complication that is preventable.

Objectives: To identify risk factors for DKA at presentation of T1DM to delineate high-risk Israeli populations that could benefit from preventative measures.

Methods: Data for this multicenter retrospective study were collected from the medical files of three pediatric diabetes centers representing three districts in Israel. Inclusion criteria were diagnosis of T1DM, age at diagnosis ≤ 17 years, permanent residency in Israel, and documentation of the presence or absence of DKA at presentation.

Results: The study population included 607 patients of whom 438 met the inclusion criteria. The mean age at diagnosis was 9.1 ± 4.5 years. DKA was present at diagnosis in 156/438 patients (35.6%). The incidence of DKA was different among the three diabetes centers (P = 0.04). The DKA group was significantly younger than the non-DKA group (8.4 ± 4.5 vs. 9.5 ± 4.4, respectively, P = 0.008). DKA was significantly associated with maternal origin (Ashkenazi Jewish origin [lower] vs. non-Ashkenazi, P = 0.04) and with paternal education level (academic [lower] vs. non-academic education, P = 0.04). Stepwise logistic regression showed that maternal Ashkenazi Jewish origin has a protective effect on DKA (odds ratio [OR] 0.4, 95% confidence interval [95%CI] 0.21–0.74, P = 0.004) and that younger age is an independent risk factor (OR 1.06, 95%CI 1.01–1.1, P = 0.02).

Conclusions: A diabetes educational program targeting high-risk population groups may reduce the prevalence of DKA nationwide.

Objectives: To evaluate glycemic control, prevalence of diabetic ketoacidosis (DKA) at presentation, diabetic complications rate, and associated autoimmune diseases in a pediatric T1DM patient population in the Negev area.

Methods: Clinical and demographic details of 168 T1DM patients were evaluated, including HbA1C levels, long-term complications, related autoimmune diseases, and insulin pump usage. The data were analyzed and the Jewish and Bedouin patient groups compared.

Results: Only 13.1% of the patients had reached the HbA1C levels recommended by the current guidelines at the first and second year follow-up visits, and 9.5% and 7.1% at the third and fourth year visits, respectively. A significant difference in HbA1c levels between Jewish and Bedouin patients was found (P = 0.045 at the first year follow-up, P ≤ 0.01 thereafter). Significant difference was found between the Jewish and the Bedouin groups regarding presentation with DKA, 33% and 56% of the patients respectively (P = 0.01).

Conclusions: Existent glycemic control in daily practice is far from the guideline goals. Bedouin ethnicity was associated with less favorable diabetes control, emphasizing the need for better awareness of T1DM and its treatment options in this population. More resources should be directed to address T1DM in the general population, especially among the Bedouin.

Background: Diabetic ketoacidosis (DKA) is a common and serious complication of diabetes mellitus (DM).

Objectives: To evaluate the clinical characteristics, hospital management and outcomes of patients with DKA.

Methods: We performed a retrospective cohort study of patients hospitalized with DKA during the period 1 January 2003 to 1 January 2010. Three groups were compared: patients with mild DKA, with moderate DKA, and with severe DKA. The primary outcome was in-hospital all-cause mortality. The secondary outcomes were 30 days all-cause mortality, length of hospital stay, and complication rate.

Results: The study population comprised 220 patients with DKA. In the mild (78 patients) and moderate (116 patients) groups there was a higher proportion of patients with type 1 DM (75.6%, 79.3%) compared with 57.7% in the severe group (26 patients, P = 0.08). HbA1C levels prior to admission were high in all three groups, without significant difference (10.9 ± 2.2, 10.7 ± 1.9, and 10.6 ± 2.4 respectively, P = 0.9). In all groups the most frequent precipitating factors were related to insulin therapy and infections. The patients with severe DKA had more electrolyte abnormalities (hypokalemia, hypomagnesemia, hypophosphatemia) compared with the mild and moderate forms of the disease. While 72.7% of the entire cohort was hospitalized in the general medical ward, 80.8% of those with severe DKA were admitted to the intensive care unit. The in-hospital mortality rate for the entire cohort was 4.1%, comparable with previous data from experienced centers. Advanced age, mechanical ventilation and bedridden state were independent predictors associated with 30 day mortality: hazard ratio (HR) 1.1, 95% confidence interval (CI) 1.02–1.11; HR 6.8, 95% CI 2.03–23.1; and HR 3.8, 95% CI 1.13–12.7, respectively.

Conclusions: Patients with DKA in our study were generally poorly controlled prior to their admission, as reflected by high HbA1c levels. Type 2 DM is frequently associated with DKA including the severe form of the disease. The most common precipitating factors for the development of DKA were related to insulin therapy and infections. Advanced age, mechanical ventilation and bedridden state were independent predictors of 30 day mortality.
