Arginine Therapy for the Treatment of Vaso-Occlusive Events in Children With Severe Sickle Cell Disease

About the study

The purpose of this study is to determine whether giving extra arginine to patients with
sickle cell disease seeking treatment for vaso-occlusive painful events (VOE) will decrease
pain scores, decrease need for pain medications or decrease length of hospital stay or
emergency department visit.
