Precipitating Factors and Outcome of Diabetic Ketoacidosis among Children and Adolescents with Type-1 Diabetes Mellitus.

Objective: To determine the precipitating factors and outcomes of diabetic ketoacidosis (DKA) among patients with type 1 diabetes mellitus.

Study design: An analytical study. Place and Duration of the Study: Department of Paediatrics, National Institute of Child Health, Karachi, Pakistan, from July to December 2022.

Methodology: Children of either gender aged up to 18 years and presenting with DKA with a known diagnosis of type-1 diabetes were enrolled. Demographic, clinical, and anthropometric characteristics of all children were noted. Laboratory investigations were sent to the institutional laboratory. Presenting features, precipitating factors, severity of DKA, and outcomes noted.

Results: Among 131 children, 101 (77.1%) were girls. The socio-economic status of 75 (57.3%) patients was the lower middle. Celiac disease was the commonest associated disease noted in 23 (17.6%) patients. A total of 123 (93.9%) children were using basal plus bolus types. Adherence to diabetes-related drug therapy was seen in 105 (80.2%) patients. At the time of presentation, vomiting, fever, abdominal pain, and respiratory distress were the most frequent presenting features reported in 77 (58.8%), 67 (51.1%), 42 (32.1%), and 34 (26.0%) patients, respectively. The most common precipitating factors for DKA were infection/illness (n=90, 68.7%) and missed insulin dose (n=16, 12.2%); no cause was identified in 25 (19.1%) patients. The mean duration of hospital stay was 5.25±2.4 days. Four patients could not survive.

Conclusion: The most common precipitating factor for the current episode of DKA were infection or illness, or missed insulin dose. Vomiting, fever, abdominal pain, and respiratory distress were the most frequent presenting features. In-hospital mortality was found to be 3% in DKA patients.
