Sleep disturbance, but not depression severity, is associated with inflammation in children and adolescents.

STUDY OBJECTIVES: We aimed to examine the association between self-rated and clinician-rated sleep disturbances and C-reactive protein (CRP), an objective marker of inflammation, in pediatric depression. METHODS: Two hundred fifty-six children and adolescents (15.2 ± 1.6 y, 72.3% female) with moderate to severe symptoms of depression participated in the study. Sleep disturbances were assessed by self-reports (Insomnia Severity Index) and clinician ratings (Kiddie-Schedule for Affective Disorder and Schizophrenia), inflammation by plasma CRP levels. RESULTS: Higher levels of CRP correlated positively with clinician-rated middle insomnia and hypersomnia. After adjusting for control variables (body mass index, tobacco, alcohol, stress, age, sex, antidepressants, sleep medication, depression severity), regression models confirmed the significant association of clinician-rated hypersomnia and middle insomnia symptoms with elevated CRP levels. In the adjusted regression models, other clinician-rated manifestations of sleep disturbance (eg, initial insomnia) and insomnia self-ratings were not significantly associated with CRP. Body mass index correlated positively with CRP, but body mass index had no mediating effect on the associations between sleep disturbances and CRP. We did not find an association between depression severity, assessed by the Children's Depression Rating Scale-Revised, and CRP. CONCLUSIONS: Results of the present study indicate a significant association of hypersomnia and middle insomnia symptoms with CRP in pediatric depression, not linked to alterations in the body mass index.

[Multisystemic Therapy (MST) for youths with severe conduct disorders - economic evaluation of the implementation in a German-speaking environment]. / Multisystemische Therapie (MST) für Jugendliche mit schweren Störungen des Sozialverhaltens.

OBJECTIVE: Multisystemic Therapy (MST) was adapted for implementation in a German-speaking environment. The study evaluates the possible economic effects of MST. METHOD: Professionals who recommended MST for youths with severe conduct disorders were asked to evaluate the probability of other forms of interventions if MST had not been used. We investigated the costs of those other forms of treatment and compared them to the costs that had actually been incurred with MST. RESULTS: Implementation of MST in a German-speaking environment showed a significant potential of cost savings compared to other intervention methods. The costs of MST per case were between 40 % and 64 % lower than these of standard interventions. CONCLUSIONS: MST is not only an effective, but also a cost-efficient form of evidence-based treatment for youths with severe conduct disorders.
