A recent study published in Medicina Clínica highlighted the association of Diabetes ketoacidosis (DKA) in patients with type 2 diabetes (T2D) and type 1 diabetes (T1D) in the population of Spain. 
The study aimed to determine the differences in DKA between patients with type 1 and type 2 diabetes mellitus. 
A total of 249 patients were included in the study. Between 2010 and 2024, all cases of DKA in a Spanish tertiary hospital were included. To identify differences between DKA in T2D and T1D, clinical and laboratory variables were collected. To evaluate 30-day mortality following a DKA event, logistic regression models were used. 
It was found that 89 patients had type 2 diabetes (T2D), while 160 patients had type 1 diabetes (T1D). The T2D group (12.5% vs. 3.2%, p = 0.005) had a higher number of cardiovascular events, despite having a favorable blood gas profile, higher bicarbonate levels, and a higher pH, as well as lower ketone body concentrations (p < 0.05). In the T2D group, the 30-day mortality rate was 13.5%, while in the T1D group, it was 1.3%. Cardiovascular events, higher urea levels, and lower Glasgow Coma Scale scores were identified by logistic regression models.
