BACKGROUND: To define the incidence of acute kidney injury (AKI), chronic kidney disease (CKD), and hypertension (HTN) in pediatric patients diagnosed with acute lymphoblastic leukemia (ALL) over a recent 9-year period.
METHODS: This study is a retrospective cohort study of all pediatric patients diagnosed with ALL at Nationwide Children's Hospital from January 1, 2008, to December 31, 2016. Patient demographic and clinical data including serum creatinine and blood pressure were collected at diagnosis up to 9 years post diagnosis.
RESULTS: A total of 222 patients were identified for this study. The overall incidence of AKI in our cohort was high, with 101 subjects (45.5%, CI 38.8-52.3%) developing AKI at least once. CKD status could only be determined in 214 patients due to limited later GFR data. The incidence of CKD was low with only 5 of 214 patients developing CKD (2.3%, CI: 0.8-5.4%). The overall incidence of HTN at diagnosis was 45.6% (95% CI: 59.1-72%), and at 1 month post diagnosis was 65.8% (95% CI: 59.1-72.0%). Chronic HTN could only be determined in 216 patients due to limited blood pressure data. Chronic HTN was noted in 34.3% of patients (74/216, 95% CI: 28-41%).
CONCLUSIONS: Among children with ALL, the incidence of AKI is relatively high at the time of diagnosis. However, development of CKD is relatively rare, suggesting good mid-term kidney prognosis. There is a high incidence of HTN at the time of diagnosis, 1 month post diagnosis, and chronic HTN that often goes untreated. A higher resolution version of the Graphical abstract is available as Supplementary information.
