Cognitive behavioral therapy in adolescents with early-onset psychosis: a randomized controlled pilot study

Abstract

Cognitive behavioral therapy for psychosis (CBT) is an effective treatment in adult patients with schizophrenia. However, no randomized controlled and blinded trial in adolescents with early-onset psychosis (EOP) has been conducted. Therefore, the present pilot study explores the acceptance, tolerability, feasibility, and safety of a modified CBT in adolescents with EOP. Twenty-five adolescents with EOP were randomized to either 9 months (20 sessions) of CBT + treatment as usual (TAU) or TAU alone. The primary endpoint was the PANSS-positive subscale (P1-7). Secondary endpoints included psychopathology, global functioning, and quality of life (QoL). Acceptance, tolerability, feasibility, and safety were assessed. Blinded assessments took place by the end of the treatment (9 months) and at 24-month follow-up. Despite improvements in both groups and lack of statistical significance between CBT + TAU and TAU regarding the primary endpoint, we observed between-group effect sizes of at least d = 0.39 in favor of CBT + TAU at post-treatment for delusions, negative symptoms, functioning and QoL after the intervention and effect sizes of at least d = 0.35 after 24 months. CBT in EOP was highly acceptable (73.5% agreed to randomization), well-tolerated (83.1% attendance rate, no drop-outs), and safe (one serious adverse event (SAE) in CBT + TAU in comparison with six SAEs in TAU). These findings suggest that CBT adapted to the needs of adolescents with EOP is a promising approach regarding negative symptoms, functioning, and QoL. CBT is a safe and tolerable treatment. However, due to the small sample size and the pilot character of the study, these conclusions are limited, and should be tested in a larger, adequately powered randomized controlled trial.

Childhood social isolation and psychotic experiences in young adulthood: a community based study

Abstract

Non-clinical psychotic experiences (PEs) occur at over twice the rate of psychotic disorders along a continuum in the general population and increase risk for progression to diagnoseable disorders. Social isolation is a risk factor for psychotic disorders, although it is unclear if childhood social isolation increases risk for experience of non-clinical PEs later in life. Data come from the Gaz et Electricité (GAZEL) Youth Study (1991–1999) and the Trajectoires Épidémiologiques en Population (TEMPO) Study (2009–2011), a community-based prospective cohort study. Of 1,227 participants whose parents completed questionnaires (1999, participants aged 7–10 years) and who were followed-up (2011, participants aged 25–37 years), 333 had childhood social isolation and young adult PE data. Lifetime prevalence of PEs was 21%. Childhood social isolation was not associated with 0–1 PE in young adulthood (p = 0.74). However, childhood social isolation predicted the experience of ≥ 2 PEs in young adulthood, controlling for gender, age, and general health status (OR = 11.5, 95% CI = 2.5, 52.0, p = 0.002). Childhood social isolation predicts the risk of experiencing two or more lifetime PEs, which may increase the risk for subsequent progression to a diagnoseable psychotic disorder.

Utility of the ADOS-2 in children with psychiatric disorders

Abstract

The Autism Diagnostic Observation Schedule (ADOS-2) is commonly used in the diagnosis of autism spectrum disorder (ASD). Although it has demonstrated good sensitivity and specificity in research settings, relatively little is known about its utility and accuracy in children and adolescents with co-occurring psychiatric disorders. We investigated this topic in children with acute psychiatric disorders. Our sample consisted of 58 patients, aged 9–18 years, admitted to a child and adolescent psychiatric inpatient unit with a suspected diagnosis of ASD. Both Modules 3 and 4 demonstrated low sensitivity (Module 3: 58.3%; Module 4: 55.6%) and specificity (Module 3: 56.5%; Module 4: 59.5%). These findings suggest that the ADOS-2 should be interpreted with caution while screening for autism in children with complex psychiatric disorders.

A common variant in OXTR rs53576 impacts topological patterns of brain functional networks

Abstract

A common variant (rs53576, G/A) in the oxytocin receptor (OXTR) gene is associated with individual differences in social behavior and may increase the risk for neuropsychiatric disorders characterized by social impairment, especially autism. Although recent functional magnetic resonance imaging (fMRI) studies have identified functional connectivity alteration in some brain regions in risk A allele carriers, it is currently unknown whether this dysfunctional connectivity causes disruption of the topological properties of brain functional networks. We applied a graph-theoretical analysis to investigate the topological properties of brain networks derived from resting-state fMRI in relation to AA homozygotes versus G allele carriers in 290 cognitive normal young adults. We found both AA homozygotes and G allele carriers demonstrated small-world properties; however, male AA homozygotes showed lower normalized clustering coefficient, small-worldness, and local efficiency compared with male G allele carriers, no differences survived after Bonferroni correction; and the inter-group differences of all three metrics exhibited an allele-load-dependent trend (AA < AG < GG), indicating a randomization shift of their brain functional networks. No significant results were observed in any global measures in female AA homozygotes as compared to female G allele carriers. Our results suggested that the topological patterns of brain functional networks were altered in OXTR rs53576 male homozygotes for the risk A allele compared with male G allele carriers, providing evidence for the disruption of integrity in large-scale intrinsic brain networks in a sex-dimorphic manner.

VGLUT2 rs2290045 genotype moderates environmental sensitivity to alcohol-related problems in three samples of youths

Abstract

The importance of Vesicular Glutamate Transporter 2 (VGLUT2)-mediated neurotransmission has been highlighted in studies on addiction-related phenotypes. The single nucleotide polymorphism rs2290045 in VGLUT2 has been associated with alcohol dependence, but it is unknown whether or how this association is affected by environmental factors. The present study determined whether the association of alcohol-related problems with the rs2290045 in the VGLUT2 gene was modified by negative and positive environmental factors. Three samples were included: a clinical sample of 131 adolescents followed from age 17 to 22; a general population sample of 1794 young adults; and a general population sample of 1687 adolescents followed from age 14 to 17. DNA was extracted from saliva and the rs2290045 (T/C) was genotyped. Alcohol-related problems were assessed using the Alcohol Use Disorders Identification Test. Stressful life events (SLE) and parenting were assessed by questionnaires. Gene-environment interactions were investigated using a dual statistical approach. In all samples (effect sizes 0.6–6.2%), and consistent with the differential susceptibility framework, T carriers exposed to SLE reported more alcohol-related problems if they had experienced poor parenting, and lower alcohol-related problems if they had received supportive parenting. T carriers not exposed to SLE reported higher alcohol-related problems if they had received supportive parenting and lower alcohol-related problems if they had received poor parenting. Among CC carriers, alcohol-related problems did not vary as a function of negative and positive environmental factors. In conclusion, in three samples of youths, alcohol-related problems were associated with an interaction of VGLUT2 rs2290045, SLE, and parenting.
