Exploring characteristics associated with first benzodiazepine prescription in patients with affective disorders and related diagnoses

Objective In patients with affective disorders, benzodiazepines (BZDs) are frequently administered at the onset, sometimes inappropriately. We sought to identify clinical variables associated with first BZD prescription in a large sample of patients with affective disorders. Methods Four hundred sixty patients with mood or anxiety disorders attending different psychiatric services were assessed comparing those who received BZD as first treatment (BZD w/) and those who did not (BZD w/o). Results More than one third (35.7%) of the total sample had received BZDs as first prescription. In relation to mood disorders, BZD w/ subjects more frequently (a) had not a psychiatrist as first therapist, (b) had anxious symptoms at onset, (c) had adjustment disorder as first diagnosis, (d) were treated as outpatients. In relation to specific diagnoses, (a) personal decision of treatment for major depressive disorder, (b) outpatient status for bipolar disorder and (c) longer duration of untreated illness for adjustment disorder were more frequently associated with first BZD prescription. For anxiety disorders, the presence of stressful life events and the diagnoses of panic disorder or specific phobias were more frequently observed in BZD w/ patients. Conclusion Patients with affective disorders frequently received BZDs as first prescription with significant differences between and within mood and anxiety disorders

Designing outcome studies to determine efficacy and safety of antipsychotics for 'real world' treatment of schizophrenia

Over the last 5 years, some studies have questioned the efficacy of second-generation antipsychotics over first-generation neuroleptics in the treatment of schizophrenia. At the same time, these study results have led to re-examination of their design particularly CATIE and CUtLASS - which essentially measured relatively short-/mid-term outcome and did not always take into account real-world clinical practice and outcome measures (e.g. prevalence of positive acute symptoms, exclusion of comorbidity with substance abuse, predominance of chronic patients, lack of quality of life/wellbeing measures, etc.). In fact, one of the greatest challenges to treatment of schizophrenia is its life-long, multifaceted, functional disability associated with progressive cognitive deterioration after each acute episode. As such, the most important goal of the treatment is not just to deal with acute episodes, but rather to improve long-term outcome. Specifically, we aim for modest improvement and then stabilization of the different clinical dimensions involved in the overall symptomatology (i.e. negative/anergic, impulsive, positive, mood and cognitive impairments), and to achieve 'clinical stabilization' after obtaining a partial or full remission of acute symptoms, thus reducing the risk of a progressive cognitive deterioration. All these aspects need to be properly evaluated in a long-run perspective

Can long-term outcomes be improved by shortening the duration of untreated illness in psychiatric disorders? A conceptual framework

The duration of untreated illness (DUI), meaning the latency to the pharmacological treatment, has been increasingly investigated in the last decade as a predictor of outcome across different psychiatric conditions, particularly in psychotic disorders. DUI is essentially computed by subtracting the age of onset of a specific disorder from the age at which the first adequate pharmacological treatment is administered. Assessment of the latency to treatment represents one of the first steps in planning early interventions. This review examines the role of the DUI in psychotic and affective disorders, focusing on neuropathological, epidemiologic, clinical and prognostic factors related to a longer latency to treatment. Through a Medline and Cochrane Library search, relevant studies up to June 2011 and other pertinent articles including meta-analyses, randomized controlled trials, naturalistic studies and clinical reviews were identified. Converging evidence indicates that a prolonged DUI negatively influences the outcome of first-episode psychosis and schizophrenia in different ways, and increasing data point toward a similar conclusion in affective disorders. Even though methodological limitations related to investigation of the DUI need to be considered, research and interventions aimed to reduce latency to treatments are object of increasing implementation worldwide. The assessment of the DUI represents one of the most important parameters to consider in this perspective, in order to quantify different latency to treatment in specific disorders and to plan related, targeted interventions.<br/

An epidemiologic and clinical overview of medical and psychopathological comorbidities in major psychoses

The presence of comorbidity in major psychoses (e.g., schizophrenia and psychotic subtypes of bipolar disorder and major depressive disorder) seems to be the rule rather than the exception in both DSM-IV and ICD-10. Examining comorbidity in major psychoses, however, requires an investigation into the different levels of comorbidity (either full-blown and subsyndromal) which should be analyzed in both psychopathological and medical fields. On one hand, the high prevalence of psychiatric comorbidity in major psychoses may be the result of the current nosographic systems. On the other hand, it may stem from a common neurobiological substrate. In fact, comorbid psychopathological conditions may share a biological vulnerability, given that dysfunction in specific brain areas may be responsible for different symptoms and syndromes. The high rates of comorbidity in major psychoses require targeted pharmacological treatments in order to effectively act on both the primary diagnosis and comorbid conditions. Nevertheless, few controlled trials in comorbid major psychoses had been carried out and treatment recommendations in this field have mostly an empirical basis. The aim of the present article is to provide a comprehensive and updated overview in relation to epidemiological and clinical issues of comorbidity in major psychoses

Mid-term and long-term efficacy and effectiveness of antipsychotic medications for schizophrenia : a data-driven, personalized clinical approach

Objective: Our aim in this article is 2-fold: first, to examine the mid-term to long-term data on efficacy, from controlled and naturalistic and other studies, in order to determine if they are consistent with the quantitative meta-analyses of mostly short-term, randomized controlled trials Our second (and most important) aim is to use these and other data to provide guidance about the potential relationship of these differences among antipsychotics to the individual patient's own experience with antipsychotic drugs in the process of shared decision-making with the patients and their significant others. Data Sources: A search of PubMed, Embase, and PsychINFO was conducted for articles published in English between January 1, 1999, and April 2011, using the search terms double-blind AND randomized AND olanzapine AND (ziprasidone OR risperidone OR quetiapine OR haloperidol OR fluphenazine OR perphenazine OR aripiprazole). Study Selection: Studies with a duration 3 months or longer, including patients with schizophrenia or schizoaffective disorder, reporting survival analysis for all-cause discontinuation and relapse or dropout due to poor efficacy were selected. Data Extraction: We extracted the number of patients relapsed due to poor efficacy and hazard rates for relapses. Data Synthesis: Overall, the efficacy patterns of both controlled effectiveness and observational long-term studies closely parallel the efficacy observed in the short-term, controlled studies. The results of Phase 1 Clinical Antipsychotic Trials of Intervention Effectiveness are very similar to, but not identical with, the controlled short-term efficacy studies, the European First-Episode Schizophrenia Trial, and naturalistic studies, The mid-term and long-term data suggest that olanzapine is more effective than risperidone and that both of these are better than the other first- and second-generation antipsychotics except for clozapine, which is the most efficacious of all. Further large differences emerged regarding the specific mid-term and long-term safety profiles of individual antipsychotics. Conclusions: Despite intraclass differences and the complexities of antipsychotic choice, the second-generation antipsychotics are important contributions not only to the acute phase but, more importantly, to the maintenance treatment of schizophrenia
