Cisplatin (CisP) causes acute kidney injury (AKI) and may lead to chronic kidney disease (CKD) and hypertension (HTN) in children. Aims: 1) Describe 3-month post-CisP CKD/HTN; 2) Determine if a) AKI during CisP treatment and b) urine neutrophil gelatinase-associated lipocalin (uNGAL) and kidney injury molecule-1 (uKIM-1) near end of CisP therapy are associated with 3-month CKD/HTN.


12-site prospective pediatric study. Exposures: a) Serum creatinine (SCr)-AKI during CisP therapy (KDIGO definition); b) Electrolyte AKI(eAKI): low serum Mg++, K+ or PO4- during therapy; c)uNGAL/KIM-1 at discharge from a late CisP cycle. Outcomes: a) CKD: urine albumin/creatinine ratio≥3mg/mmol(≥7.5mg/mmol if <2 years old), urine protein/creatinine ratio≥15mg/mmol or SCr-estimated glomerular filtration rate<90mL/min/1.73m2; b) HTN: blood pressure≥95thpercentile (adults:≥140/90mmHg) or treated for HTN. Univariate tests and multiple logistic regression were performed to evaluate exposure-outcome relations and adjusted associations.


Of 154/158 with 3-month data: 77(50%) boys; median[IQR] age: 6[3-12] years. 96/142(68%) had CKD; 14/141(10%) had HTN; 100/154(65%) had CKD or HTN. SCr-AKI, ≥Stage 2 SCr-AKI and eAKI+SCr-AKI were associated with 3-month HTN(Table). AKI was not associated with CKD(Table). Adjusting for age and gender, only ≥Stage 2 SCr-AKI was associated with 3-month HTN (adjOR 4.4(95% CI 1.1-18.4)). Biomarkers were not associated with CKD or HTN(Table).


CKD and HTN are common 3 months after CisP. AKI is associated with 3-month HTN. Ongoing 3-year follow-up will determine if associations change and/or persist. Measures to reduce HTN after cancer therapy are needed.
