Quetiapine augmentation of SRIs in treatment refractory obsessive-compulsive disorder: a double-blind, randomised, placebo-controlled study [ISRCTN83050762]

BACKGROUND: Although serotonin reuptake inhibitors are effective in the treatment of OCD, many patients fail to respond to these agents. Growing evidence from open-label and placebo-controlled trials suggests a role for augmentation of SRIs with atypical antipsychotics in OCD. Quetiapine is generally well tolerated and previous open-label data has produced mixed results in OCD and additional controlled data is needed. METHODS: We undertook a double-blind, randomised, parallel-group, flexible-dose, placebo-controlled study of quetiapine augmentation in subjects who had responded inadequately to open-label treatment with an SRI for 12 weeks. Following informed consent and screening, forty-two subjects were randomised to either placebo or quetiapine for six weeks. RESULTS: There was significant improvement from baseline to endpoint on the Yale-Brown Obsessive-Compulsive Scale in both the quetiapine and placebo groups (quetiapine, n = 20, p < 0.0001; placebo, n = 21, p = 0.001) with 40% (n = 8) of quetiapine and 47.6% (n = 10) of placebo treated subjects being classified as responders. Quetiapine did not demonstrate a significant benefit over placebo at the end of the six-week treatment period (p = .636). Similarly quetiapine failed to separate from placebo in the subgroup of subjects (n = 10) with co-morbid tics. Quetiapine was generally well tolerated. CONCLUSIONS: In this study, quetiapine augmentation was no more effective than placebo augmentation of SRIs. A number of limitations in study design make comparisons with previous studies in this area difficult and probably contributed to our negative findings. Future work in this important clinical area should address these limitations

Thought Problems from Adolescence to Adulthood: Measurement Invariance and Longitudinal Heritability

This study investigates the longitudinal heritability in Thought Problems (TP) as measured with ten items from the Adult Self Report (ASR). There were ~9,000 twins, ~2,000 siblings and ~3,000 additional family members who participated in the study and who are registered at the Netherlands Twin Register. First an exploratory factor analysis was conducted to examine the underlying factor structure of the TP-scale. Then the TP-scale was tested for measurement invariance (MI) across age and sex. Next, genetic and environmental influences were modeled on the longitudinal development of TP across three age groups (12–18, 19–27 and 28–59 year olds) based on the twin and sibling relationships in the data. An exploratory factor analysis yielded a one-factor solution, and MI analyses indicated that the same TP-construct is assessed across age and sex. Two additive genetic components influenced TP across age: the first influencing TP throughout all age groups, while the second arises during young adulthood and stays significant throughout adulthood. The additive genetic components explained 37% of the variation across all age groups. The remaining variance (63%) was explained by unique environmental influences. The longitudinal phenotypic correlation between these age groups was entirely explained by the additive genetic components. We conclude that the TP-scale measures a single underlying construct across sex and different ages. These symptoms are significantly influenced by additive genetic factors from adolescence to late adulthood

Longitudinal association between motor and obsessive compulsive symptoms in patients with psychosis and their unaffected siblings

Little is known about the co-prevalence of obsessive compulsive symptoms (OCS) and motor symptoms in patients with psychotic disorders. Cross-sectional associations between OCS and motor symptoms were assessed at baseline and at 3years follow-up in patients (n=726) with psychotic disorders and in their unaffected siblings (n=761) from the Dutch Genetic Risk and Outcome of Psychosis (GROUP) study. Furthermore, longitudinal associations between changes in OCS and motor symptoms were evaluated. At baseline, OCS was not associated with any motor symptom (akathisia, dyskinesia, parkinsonism or dystonia) in patients. At follow-up, patients with OCS reported significantly more akathisia. Dividing the patients into four groupsno OCS, OCS remission with OCS only at baseline, OCS de novo with OCS only at follow-up and a persistent OCS grouprevealed that the OCS de novo group already reported more akathisia at baseline compared to the no-OCS group. At follow-up, both the OCS de novo and the persistent OCS group reported more akathisia. These results remained significant after correcting for relevant confounders clozapine, GAF score, PANSS-negative score and IQ. Motor symptoms at baseline were significantly associated with OCS at follow-up, but not the other way around. In siblings, OCS at baseline was associated with akathisia, but this association was lost at follow-up. Results suggest that motor symptoms might precede co-occurring OCS in patients with psychotic disorders. However, no inference can be made about causality, and further prospective research is needed to investigate this assumption

deficit and hyperactivity disorder

We investigated whether the affective temperaments of mothers and maternal depression before and during the index pregnancy are related to the development of Attention-Deficit Hyperactivity Disorder (ADHD) in their children. One hundred and twenty children were screened for the diagnosis of ADHD. After exclusion and inclusion criteria were applied for children and their mothers, we compared the mothers of children with (n = 63) and without ADHD (n = 60) in terms of affective temperament traits, depression before and during the index pregnancy, and some environmental risk factors. The rate of boys were significantly higher among children with ADHD compared to healthy controls. The mothers of children with ADHD had significantly lower education levels, more cigarette consumption during pregnancy, and more depression rates before the pregnancy than those of healthy children. Male gender (p = .002), Hamilton Depression Rating Scale (HDRS) (p = .002), cyclothymic (p = .022), irritable (p = .035) and anxious temperament scores (p = .016) significantly predicted the association between the mothers and their children with ADHD. Our findings might suggest that male child gender, the severity of depression at index pregnancy, higher cyclothymic, irritable, and anxious temperament scores in mothers may constitute as important risk factors for the development of ADHD in their children.Impact statement What is already known on this subject? Although the effects of maternal depression on ADHD were extensively investigated, the relationship between affective temperament traits of mothers and ADHD in their children has not been sufficiently examined. To investigate the roles of maternal affective temperament traits and pregnancy-related depression on offspring ADHD would help us to understand the etiopathogenic bases of ADHD. What do the results of this study add? Cyclothymic, irritable and anxious temperaments of mothers were significantly associated with the offspring ADHD after adjusting for the gender, maternal smoking, prepartum and antenatal depression.C1 [Sair, Yasan Bilge; Sevincok, Levent] Adnan Menderes Univ, Dept Psychiat, Aydin, Turkey.[Sevincok, Doga] Adnan Menderes Univ, Dept Child & Adolescent Psychiat, Aydin, Turkey.[Kutlu, Ayse] Dr Behcet Uz Child Dis & Pediat Surg Training & R, Dept Child & Adolescent Psychiat, Izmir, Turkey.[Cakaloz, Burcu] Pamukkale Univ, Dept Child & Adolescent Psychiat, Denizli, Turkey.[Cakaloz, Burcu] Gelisim Univ, Dept Child & Adolescent Psychiat, Istanbul, Turkey

The subthreshold autistic traits in patients with adult-onset obsessive-compulsive disorder: A comparative study with adolescent patients

SUMMARY. Objective. The primary objective of this study was to compare the adult-onset and adolescent obsessive-compulsive disorder (OCD) patients in terms of the subthreshold autistic traits. Methods. 29 adolescent, and 45 adult-onset OCD patients were assessed by Autism-spectrum Quotient (AQ). Results. The ratio of males to females, the frequency of ritualistic compulsions, and the mean number of lifetime compulsions were significantly higher in adolescents with OCD compared to adult-onset patients. Adult-onset OCD patients had significantly higher scores on total, social skills, attention shifting, and imagination subscales of AQ than adolescent OCD patients. The mean number of compulsions, attention shifting scores of AQ, and female gender significantly predicted the distinction between adolescent and adult-onset OCD patients. In adult-onset patients, there were significant correlations between the mean number of lifetime obsessions and total, social skills, attention switching, communication, and imagination subscale scores of AQ. Conclusions. We suggest that subthreshold autistic traits may play a significant role in the occurence of obsessive-complusive symptoms (OCS) in adult-onset OCD. Autistic traits seemed to be higher and had an closer relationship with the frequency of lifetime obsessions in AO-OCD patients than in adolescent patients. © 2019 Il Pensiero Scientifico Editore s.r.l..
