Abstract Objectives Although Acute Kidney Injury (AKI) has been described among childhood diabetes ketocidosis (cDKA) there is scarcity of literature on the role of concomitant rhabdomyolysis. Method A retrospective chart review was undertaken (2014–2018) to identify cDKA who developed AKI and had evidence of rhabdomyolysis defined by serum creatine phosphokinase (CPK) > 5 times upper limit of normal. Result 46 cDKA were identified. Ten (22%) developed AKI with 6/10 reaching peak AKI Stage 3 and 8/10 had co-current rhabdomyolysis. In comparison to non rhabdomyolysis group, cDKA with rhabdomyolysis were at presentation significantly more likely to be hypotensive and have higher corrected sodium and calculated osmolality. Subsequently they were more likely to develop lower trough potassium levels during treatment. Five patients, all with rhabdomyolysis, needed dialysis: median duration 9 days (range 4–35). Three children in our cohort died, all from infection complications during treatment, one in AKI only group who did not receive dialysis and two in AKI with rhabdomyolysis on dialysis. Conclusion Rhabdomyolysis was common among our cohort of cDKA with AKI and was associated with high morbidity and mortality. Rapid flux in electrolytes and osmolality may be important precipitating factors. We recommend larger prospective studies exploring the importance of rhabdomyolysis among cDKA with AKI.
