Hepatocyte nuclear factor-1 A maturity-onset diabetes of the young (HNF1A - MODY) is a monogenic form of diabetes caused by heterozygous mutations on HNF1A. Currently, a history of diabetic ketoacidosis (DKA) is an exclusion criterion for genetic testing for MODY.

In this article, we describe two unrelated patients aged 17 and 24 years with severe DKA developed several years after the diagnosis of HNF1A-MODY. Both patients were treated with insulin, but their metabolic control was poor (HbA1c 15%, 140 mmol/mol and 13 %, 119 mmol/mol, respectively) due to noncompliance and missed insulin injections.

In both patients, DKA followed a course of recurrent vomiting with dehydration and prerenal acute kidney injury. Their glycemia, blood pH, and base excess at admission were 97 mmol/L [1,748 mg/dL], 6.80, and - 33 mmol/L (patient 1) and 34 mmol/L [613 mg/dL], 7.03, and - 14 mmol/L (patient 2).

This anecdotal observation supports the notion that a history of DKA does not exclude MODY.
