Serum irisin and caspase-9 levels in adolescents with substance use disorder: a case-control study.

Background: During adolescence, individuals experience rapid changes in physical, cognitive, emotional, behavioral, and social aspects of their life. Due to certain risks which arise during the developmental period of adolescence, substance use and addiction are encountered as a public health problem. Studies on biochemical parameters and puberty are limited. In this study, adolescents with substance use disorder were compared to healthy individuals in terms of sociodemographic characteristics and serum irisin and caspase-9 levels. Methods: The study group consisted of 32 adolescents with substance use disorder and the control group was comprised of 29 healthy adolescents. The sociodemographic characteristics and serum irisin and caspase-9 levels of the groups were compared. Results: The study group performed lower than the control group in terms of duration of education and continuing education. Serum caspase-9 levels were found to be significantly higher in the study group compared to the control group. There was no difference in irisin levels of the groups. Conclusions: It was determined that substance use negatively affects educational aspects and may also lead to certain destructive biological effects in adolescents. In order to reveal the effect of substance use on adolescents in more detail, studies with larger samples are needed. [ABSTRACT FROM AUTHOR]
