Efficacy of atomoxetine in adults with attention deficit hyperactivity disorder:An integrated analysis of the complete database of multicenter placebo-controlled trials

Persistence of attention deficit hyperactivity disorder (ADHD) into adulthood can be disabling or lead to substantial impairment. Several clinical trials of atomoxetine (ATX) in adults with ADHD have been reported following the National Institute for Health and Clinical Excellence (NICE) guidelines issued in 2008. We performed an integrated analysis of all Eli Lilly-sponsored, randomized, double-blind, placebo-controlled studies of ATX in adults with ADHD completed as of May 2012. Individual patient data were pooled from six short-term (10–16 week) studies (1961 patients) and three longer-term (six-month) studies (1413 patients). In the short-term analysis, ATX patients achieved a significantly greater mean reduction in ADHD symptoms than placebo patients (−12.2 vs −8.1; Conners’ Adult ADHD Rating Scale–Investigator-Rated: Screening Version (CAARS-Inv: SV); p<0.001). In the longer-term analysis, respective improvements after six months were −13.2 vs −9.7 (p<0.001). Response rates at study endpoints for ATX vs placebo, based on CAARS-Inv: SV improvement ≥30% and Clinical Global Impressions of ADHD-Severity (CGI-ADHD-S) ≤3 were 34.8% vs 22.3% in the short-term and 43.4% vs 28.0% after six months, and CAARS-Inv: SV improvements ≥40% were 41.3% vs 25.3% in the short-term and 44.0% vs 31.4% after six months (all p<0.001). Overall, ATX had a clinically significant effect in adults with ADHD, with reductions in core symptoms and clinically meaningful responder rates

Typology of patients with fibromyalgia: cluster analysis of duloxetine study patients

Background: To identify distinct groups of patients with fibromyalgia (FM) with respect to multiple outcome measures. Methods: Data from 631 duloxetine-treated women in 4 randomized, placebo-controlled trials were included in a cluster analysis based on outcomes after up to 12 weeks of treatment. Corresponding classification rules were constructed using a classification tree method. Probabilities for transitioning from baseline to Week 12 category were estimated for placebo and duloxetine patients (Ntotal = 1188) using logistic regression. Results: Five clusters were identified, from “worst” (high pain levels and severe mental/physical impairment) to “best” (low pain levels and nearly normal mental/physical function). For patients with moderate overall severity, mental and physical symptoms were less correlated, resulting in 2 distinct clusters based on these 2 symptom domains. Three key variables with threshold values were identified for classification of patients: Brief Pain Inventory (BPI) pain interference overall scores of 80% of patients were in the 3 worst categories. Duloxetine patients were significantly more likely to improve after 12 weeks than placebo patients. A sustained effect was seen with continued duloxetine treatment. Conclusions: FM patients are heterogeneous and can be classified into distinct subgroups by simple descriptive rules derived from only 3 variables, which may guide individual patient management. Duloxetine showed higher improvement rates than placebo and had a sustained effect beyond 12 weeks

Relationships among neurocognition, symptoms and functioning in patients with schizophrenia: a path-analytic approach for associations at baseline and following 24 weeks of antipsychotic drug therapy

<p>Abstract</p> <p>Background</p> <p>Neurocognitive impairment and psychiatric symptoms have been associated with deficits in psychosocial and occupational functioning in patients with schizophrenia. This post-hoc analysis evaluates the relationships among cognition, psychopathology, and psychosocial functioning in patients with schizophrenia at baseline and following sustained treatment with antipsychotic drugs.</p> <p>Methods</p> <p>Data were obtained from a clinical trial assessing the cognitive effects of selected antipsychotic drugs in patients with schizophrenia. Patients were randomly assigned to 24 weeks of treatment with olanzapine (n = 159), risperidone (n = 158), or haloperidol (n = 97). Psychosocial functioning was assessed with the Heinrichs-Carpenter Quality of Life Scale [QLS], cognition with a standard battery of neurocognitive tests; and psychiatric symptoms with the Positive and Negative Syndrome Scale [PANSS]. A path-analytic approach was used to evaluate the effects of changes in cognitive functioning on subdomains of quality of life, and to determine whether such effects were direct or mediated via changes in psychiatric symptoms.</p> <p>Results</p> <p>At baseline, processing speed affected functioning mainly indirectly via negative symptoms. Positive symptoms also affected functioning at baseline although independent of cognition. At 24 weeks, changes in processing speed affected changes in functioning both directly and indirectly via PANSS negative subscale scores. Positive symptoms no longer contributed to the path-analytic models. Although a consistent relationship was observed between processing speed and the 3 functional domains, variation existed as to whether the paths were direct and/or indirect. Working memory and verbal memory did not significantly contribute to any of the path-analytic models studied.</p> <p>Conclusion</p> <p>Processing speed demonstrated direct and indirect effects via negative symptoms on three domains of functioning as measured by the QLS at baseline and following 24 weeks of antipsychotic treatment.</p

Prevalence of ADHD in nonpsychotic adult psychiatric care (ADPSYC) : A multinational cross-sectional study in Europe

Attention-deficit/hyperactivity disorder (ADHD) often persists into adulthood. This study was designed to estimate the prevalence of ADHD in adult psychiatric outpatients in several European countries. ADHD diagnosis was made using the Diagnostic Interview for ADHD in Adults, version 2.0 (DIVA), according to criteria of the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, Text Revision (DSM-IV-TR) and 5th Edition (DSM-5). Of 5662 patients present/approached, 2284 (40.3 %) consented, of whom 1986 patients (87.0 %) completed the study. Based on the DIVA, and applying DSM-IV-TR or DSM-5 criteria, 15.8 % (95 % confidence interval [CI] 14.2 %-17.4 %) or 17.4 % (95 % CI 15.7 %-19.0 %) of patients were diagnosed with ADHD, respectively. The prevalence of ADHD was 15.3 % when counting as non-ADHD those patients who screened positive but did not complete the DIVA (DSM-5). Estimates from this study indicate that a relevant part of the psychiatric outpatient care population suffers from ADH

Differential diagnosis, comorbidity, and treatment of attention-deficit/hyperactivity disorder in relation to bipolar disorder or borderline personality disorder in adults

BACKGROUND: Attention-deficit/hyperactivity disorder (ADHD) in adults can resemble, and often co-occurs with, bipolar disorder (BD) and borderline personality disorder (BPD). This can lead to mistaken diagnoses and ineffective treatment, resulting in potentially serious adverse consequences. All three conditions can substantially impair well-being and functioning, while BD and BPD are associated with suicidality. OBJECTIVES: To update clinicians on the overlap and differences in the symptomatology of ADHD versus BD and BPD in adults; differential diagnosis of ADHD from BD and BPD in adults; and diagnosis and treatment of adults with comorbid ADHD-BD or ADHD-BPD. METHODS: We searched four databases, referred to the new Diagnostic and Statistical Manual of Mental Disorders, 5th edition, used other relevant literature, and referred to our own clinical experience. RESULTS: ADHD coexists in ∼20% of adults with BD or BPD. BD is episodic, with periods of normal mood although not necessarily function. In patients with comorbid ADHD-BD, ADHD symptoms are apparent between BD episodes. BPD and ADHD are associated with chronic trait-like symptoms and impairments. Overlapping symptoms of BPD and ADHD include impulsivity and emotional dysregulation. Symptoms of BPD but not ADHD include frantically avoiding real/imagined abandonment, suicidal behavior, self-harm, chronic feelings of emptiness, and stress-related paranoia/severe dissociation. Consensus expert opinion recommends that BD episodes should be treated first in patients with comorbid ADHD, and these patients may need treatment in stages (e.g. mood stabilizer[s], then a stimulant/atomoxetine). Data is scarce and mixed about whether stimulants or atomoxetine exacerbate mania in comorbid ADHD-BD. BPD is primarily treated with psychotherapy. Principles of dialectical behavioral treatment for BPD may successfully treat ADHD in adults, as an adjunct to medication. No fully evidence-based pharmacotherapy exists for core BPD symptoms, although some medications may be effective for individual symptom domains, e.g. impulsivity (shared by ADHD and BPD). In our experience, treatment of ADHD should be considered when treating comorbid personality disorders. CONCLUSIONS: It is important to accurately diagnose ADHD, BD, and BPD to ensure correct targeting of treatments and improvements in patient outcomes. However, there is a shortage of data about treatment of adults with ADHD and comorbid BD or BPD
