Glucocorticoids are known to cause psychiatric disorders including depression. Prednisolone (PSL) is one of the most widely used synthetic glucocorticoids to treat various medical diseases; however, little is known about PSL-induced behavioral changes and its molecular basis in the brain. Growing evidence has implicated that hippocampal remodeling or damage play a role in the pathogenic effect of glucocorticoids. In this study, mice were administered PSL (50 or 100mg/kg) or vehicle for 6 or 7 days and subjected to a series of behavioral tests, i.e., open field, elevated plus maze, prepulse inhibition, forced swim, and tail suspension tests. Hippocampal tissues were subject to microarray analysis using the GeneChip Mouse Genome 430 2.0 Array (Affymetrix) containing 45,101 probes of transcripts. Increased anxiety- and depression-like behaviors assessed with open field, elevated plus maze, and tail suspension tests were observed. Microarray analysis detected 108 transcripts with a fold change of >2.0 or <0.5 in which many cell-death-related genes were found. The microarray data was validated by quantitative reverse transcriptase-polymerase chain reaction analysis. Our results demonstrated that PSL causes anxiety- and depression-like behaviors, and suggest that altered gene expressions related to hippocampal remodeling or damage are involved in the effect of PSL on such behaviors.

Introduction. The objective of this work was to define the frequency and severity of steroid related behavioral side effects in children with steroid sensitive idiopathic nephrotic syndrome (SSNS) during Treatment for relapse. Methods. 30 pediatric patients with steroid sensitive nephrotic syndrome were studied; known as SSNS at complete remission or low dose of Prednisolone and have relapse on follow up. All children in this study were subjected to full history taking, thorough clinical examination, assessment socioeconomic standard, and assessment of pediatric quality of life, a battery of psychometric tests included pediatric anxiety, depression, and aggression scores. Results. Our results revealed that there are highly significant increase in the mean values of anxiety, depression and aggression among cases starts to appear on week one and extends to three, five and seven weeks compared to baseline. In the seventh week of follow up cases show significant positive correlation between prednisone doses and mean values of anxiety and depression scores and aggression. Conclusion. we concluded that all studied children with SSNS often experience significant problems with anxiety, depression, and increased aggression during high dose steroid therapy.
