Results:
Forty-five patients enrolled in the study, 21 completed ABPMs. Fifteen patients (33%, 95% CI: 20-49%) developed AKI at least once. Thirteen (29%, 95% CI: 16-44%) had hyperfiltration, and 11 (24%) had abnormal proteinuria and/or albuminuria. Prevalence of HTN based on clinic measurements was 42%. In the 21 ABPM patients, 14 had abnormal results (67%, 95% CI: 43-85%) with the majority (11/21) demonstrating abnormal nocturnal dipping pattern. .
Conclusions :
Among children with ALL, there is a high prevalence of past AKI. The presence of hyperfiltration, proteinuria and/or albuminuria at 1-5 years after ALL diagnosis suggest real risk of developing CKD over time. There is a high prevalence of HTN on casual BP readings and even higher prevalence of abnormal ABPM in this group. The high prevalence of impaired nocturnal dipping by ABPM indicates an increased risk for future cardiovascular or cerebral ischemic events.
