Background: Urine ketone test is commonly used to screen for diabetic ketoacidosis (DKA). Ketonuria also develops in patients with disease conditions other than DKA. However, the prevalence of DKA in patients with ketonuria is not known. We investigated the prevalence of ketonuria and characteristics of patients with ketonuria and estimated the prevalence of DKA among them to study the clinical significance of ketonuria as an indicator of DKA.
Methods: We studied 1,314 adult and 1,027 pediatric patients who underwent urinalysis. The prevalence of ketonuria in the different groups of patients, classified according to the types of their visits to the institution, was investigated, and the relationships between ketonuria and albuminuria, glycosuria, and bilirubinuria were evaluated.
Results: The overall prevalence of ketonuria was 9.1%. The prevalences of ketonuria in adult and pediatric patients were 4.3% and 15.2%, respectively. The prevalences of ketonuria were the highest in the adult (9.7%) and pediatric (28%) patients in the group that had visited the emergency department. Among patients with ketonuria, 7% adult and 3.8% pediatric patients showed glycosuria.
Conclusions: This study showed that the prevalence of DKA in patients with ketonuria, defined as the simultaneous presence of ketone bodies and glucose in urine, was only 7%. Therefore, we concluded that ketonuria might be clinically significant as an indicator of acute or severe disease status rather than of DKA.
