Therapeutic drug monitoring in adolescents with anorexia nervosa for safe treatment with adjunct olanzapine.

OBJECTIVE: Medication is commonly used in anorexia nervosa (AN) despite largely missing high grade evidence. Olanzapine (OLZ) is the best-evidenced substance used off-label in this group, with conflicting outcome regarding BMI, clinical and safety parameters. Therefore, it is important to strictly assure quality of treatment with OLZ in AN by using 'Therapeutic Drug Monitoring' according to AGNP-guidelines, including serum levels and adverse drug reactions (ADRs) to support safety for adolescents with AN and attempt to generate an initial age- and disorder-specific therapeutic reference range. METHOD: Sixty-five adolescents with AN (aged 10-18) treated with OLZ (98% female; 97.5% AN-restricting-type) were prospectively observed, ADRs reported, and correlations between dosage and serum levels measured at trough level were calculated, a preliminary therapeutic range defined. RESULTS: Mean dosage of OLZ was 8.15 (SD: 2.91) mg and 0.19 (SD: 0.07) mg/kg respectively, average concentration was 26.57 (SD: 13.46) ng/mL. Correlation between daily dosage/dosage per kg and serum level was 0.72 (**p < 0.001)/0.65 (**p < 0.001), respectively. ADRs with impairment were rare (6.3%). 75% improved clinically (CGI). BMI increased significantly by 1.5 kg/m2 (t = 10.6, p < 0.001). A preliminary therapeutic reference range is 11.9 and 39.9 ng/mL. CONCLUSIONS: OLZ in the hands of specialists is a well-tolerated and safe treatment adjunct for adolescents with AN.

White matter integrity is disrupted in adolescents with acute anorexia nervosa: A diffusion tensor imaging study.

Anorexia nervosa (AN) is a highly debilitating mental illness with multifactorial etiology. It oftentimes begins in adolescence, therefore understanding the pathophysiology in this period is important. Few studies investigated the possible impact of the acute state of illness on white matter (WM) tissue properties in the developing adolescent brain. The present study expands our understanding of the implications of AN and starvation on WM integrity. 67 acutely ill adolescent patients suffering from AN restricting type were compared with 32 healthy controls using diffusion tensor imaging assessing fractional anisotropy (FA) and mean diffusivity (MD). We found widespread alterations in the vast majority of the WM regions with significantly decreased FA and increased MD in the AN group. In this highly selective sample in the acute stage of AN, the alterations are likely to be the consequence of starvation. Still, we cannot rule out that some of the affected regions might play a key role in AN-specific psychopathology.

Short-Term Outcome of Inpatient Treatment for Adolescents with Anorexia Nervosa Using DSM-5 Remission Criteria.

This study evaluated the short-term outcome of a multimodal inpatient treatment concept for adolescents with anorexia nervosa (AN). In this prospective observational study, a cohort of 126 female adolescents with AN (age range: 11-17, mean age: 14.83) was longitudinally followed from admission to discharge (average duration of stay: 77 days). We used gold-standard clinical interviews and self-report data, as well as DSM-5 remission criteria, to evaluate the treatment outcome. From admission to discharge, body-mass-index (BMI) significantly improved by 2.6 kg/m2. Data from clinical interviews and self-reports yielded similar improvements in restraint eating and eating concerns (large effects). Lower effects were observed for variables assessing weight/shape concerns and drive for thinness. At discharge, 23.2% of patients showed full remission of AN, 31.3% partial remission, and 45.5% no remission according to DSM-5 criteria. Differences in remission groups were found regarding AN severity, age at admission, and use of antidepressant medication. Living with both parents, longer duration of inpatient treatment and the use of antipsychotic medication were significantly associated with higher BMI change. The findings provide evidence for the short-term effectiveness of our inpatient treatment concept. We recommend using DSM-5 based remission criteria to evaluate the treatment outcome to improve the comparability of studies.

Research in minors with a recent history of trauma-A bold venture?

Little research has been performed so far on the mental health state of grieving and recently traumatized children. "The Buoy" ("Die Boje"), a low threshold ambulatory provides non-bureaucratic help and short time psychotherapy to children and adolescents in need of professional support at no charge and treats about 1400 minors per year. Whilst performing a study on these patients with special regard to their social network, we found the process of recruitment to be extraordinarily challenging. Only about 25% of the eligible patients could be recruited successfully within during the period of one year. In this paper we try to examine the barriers we had to overcome in gaining access to the sensitive field of grieving and traumatized children and adolescents who rely on low threshold psychotherapeutic and neuropsychiatric support and analyze the factors leading to the high number of dropouts. In addition, the consequences for our results will be discussed.

Social anxiety disorder and emotion regulation problems in adolescents.

BACKGROUND: Social anxiety disorder (SAD) in adolescents may be associated with the use of maladaptive emotion regulation (ER) strategies. The present study examined the use of maladaptive and adaptive ER strategies in adolescents with SAD. METHODS: 30 adolescents with SAD (CLIN) and 36 healthy adolescents for the control group (CON) aged between 11 and 16 years were assessed with the standardized questionnaires PHOKI (Phobiefragebogen für Kinder und Jugendliche) for self-reported fears as well as FEEL-KJ (Fragebogen zur Erhebung der Emotionsregulation bei Kindern und Jugendlichen) for different emotion regulation strategies. RESULTS: Compared to controls, adolescents with SAD used adaptive ER strategies significantly less often, but made use of maladaptive ER strategies significantly more often. There was a significant positive correlation between maladaptive ER and social anxiety in adolescents. Examining group differences of single ER strategy use, the CLIN and CON differed significantly in the use of the adaptive ER strategy reappraisal with CLIN reporting less use of reappraisal than CON. Group differences regarding the maladaptive ER strategies withdrawal and rumination, as well as the adaptive ER strategy problem-solving were found present, with CLIN reporting more use of withdrawal and rumination and less use of problem-solving than CON. CONCLUSIONS: Promoting adaptive emotion regulation should be a central component of psychotherapy (cognitive behavioral therapy-CBT) for social anxiety in adolescents from the beginning of the therapy process. These findings provide rationale for special therapy programs concentrating on the establishment of different adaptive ER strategies (including reappraisal). As an increased use of maladaptive ER may be associated with SAD in adolescents, it may be paramount to focus on reduction of maladaptive ER (for example withdrawal and rumination) from the beginning of the psychotherapy process. Incorporating more ER components into psychotherapy (CBT) could increase the treatment efficacy. Further investigations of the patterns of emotion regulation in specific anxiety groups like SAD in adolescents is needed to continue to optimize the psychotherapy (CBT) concept.
