BACKGROUND: Low-molecular-weight heparin is cleared through the kidneys and is commonly used for anticoagulation in the pediatric population. OBSERVATION: We present 3 challenging cases of children requiring anticoagulation in the context of acute kidney injury, nephrotic syndrome, and hemodialysis. CONCLUSIONS: A significant change in anti-factor Xa (anti-Xa) levels-used for drug monitoring-should prompt an assessment of renal function. In nephrotic syndrome, anti-Xa levels should be closely monitored when there is a change in the status of nephrotic disease activity. In hemodialysis patients, enoxaparin at once daily reduced dosing should be considered with trough and peak anti-Xa levels monitoring.
