22 Percent of Indian Children with Diabetic Ketoacidosis Develop Kidney Injury, Reveals Hospital-Based Study

The study found statistically significant differences in clinical parameters between the AKI and non-AKI groups. Specifically, age, body mass index (BMI), corrected sodium, and blood urea levels were notably different. Children who developed AKI had a longer median hospital stay of 10 days, compared to 6 days for those without AKI. Similarly, time to resolution of metabolic acidosis was longer—96 hours versus 39 hours.

Commenting on whether the 22.6% incidence was surprising, Dr. Tadakanahalli noted that the proportion varies widely across studies and regions, ranging from 7% to as high as 66%. “One of the key reasons for this variability is the difference in criteria used to define AKI. For instance, using urine output as a criterion can be problematic in DKA due to various confounding factors. Also, the proportion of new-onset diabetes cases in each cohort can influence AKI incidence, as new-onset DKA is generally associated with lower rates of kidney injury,” he explained.

When asked which predictors clinicians should pay attention to, he emphasized that corrected sodium and blood urea levels were indicative of the severity of dehydration, which is a major risk factor for AKI. Age and BMI were also statistically significant in their analysis. “Children presenting with severe DKA should be closely monitored for renal function, especially if these parameters are abnormal,” he advised.

To minimize adverse outcomes such as prolonged hospitalization and delayed recovery, Dr. Tadakanahalli stressed the importance of early recognition and timely management of AKI. He recommends that pediatricians adhere to established protocols, especially the International Society for Pediatric and Adolescent Diabetes (ISPAD) guidelines for fluid correction in DKA.

“The key takeaway for clinicians managing DKA is to identify dehydration severity early, monitor kidney function proactively, and intervene promptly if signs of kidney injury are present,” he concluded.

The study underlines the need for greater awareness among pediatricians and emergency physicians treating DKA, particularly in resource-limited settings where delays in recognizing AKI can significantly impact recovery and outcomes.
