Objectives. The objective of this study was to define the frequency and sev
erity of steroid-related behavioral side effects in children with steroid-s
ensitive idiopathic nephrotic syndrome (SSNS) during treatment for relapse.
Study Design. We conducted a prospective, repeated-measures study in which
10 children with SSNS underwent behavioral assessment using the Child Behav
ior Checklist at baseline and during high dose prednisone therapy for relap
se.
Results. Of the 10 children, 8 had normal behavior at baseline. Of these 8
children, 5 had Child Behavior Checklist scores above the 95th percentile f
or anxious/depressive behavior and/or aggressive behavior during relapse. S
uch scores are in the range normally considered appropriate for referral to
a mental health provider. The 2 children who had abnormal behavior at base
line also experienced a worsening of their behavior during relapse. The beh
avioral changes occurred almost exclusively at prednisone doses of 1 mg/kg
every 48 hours or more. Regression analysis showed that prednisone dose was
a strong predictor of abnormal behavior, especially increased aggression.
Conclusion. Children with SSNS often experience serious problems with anxie
ty, depression, and increased aggression during high-dose prednisone therap
y for relapse.
