Diabetic ketosis vs ketoacidosis as initial presentation of pediatric type 1 diabetes mellitus. Associated features and rate of progression during the first two years after diagnosis.

In this study we described the clinical and laboratory features of children presented with diabetic ketosis or diabetic ketoacidosis at diagnosis of type 1 diabetes (T1DM) and evaluated its course up to 2 years after initial diagnosis to investigate the progression rate of T1DM in both groups. This was a prospective longitudinal cohort study that included 59 children and adolescents presented with either diabetic ketosis (DK) (n = 27) or diabetic ketoacidosis (DKA) (n = 32) at their first diagnosis with T1DM. Apart from the metabolic state of presentation at diagnosis, differences in the other basic clinical and laboratory features of both DK and DKA were not statistically significant (age, BMI, pre- diagnosis symptomatic period, HbA1c, multiplicity of autoantibodies positivity, fasting insulin, and total IgG levels), except from the C-peptide and IgA levels which were lower in DKA (p < 0.05). Regarding family history, only the DK group had individuals with a parent diagnosed with T1DM (p = 0.001). During follow-up there was no difference in the levels of HbA1c, basal insulin dose, and insulin/carbohydrate ratio between the DK and DKA group at 3,6,12 and 24 months' time points. The severity of presentation of T1DM (DK or DKA) is not associated to the rate of progression of the disease course after diagnosis.
