World Federation of Societies of Biological Psychiatry (WFSBP) guidelines for treatment of anxiety, obsessive-compulsive and posttraumatic stress disorders - Version 3. Part I: Anxiety disorders.

AIM: This is the third version of the guideline of the World Federation of Societies of Biological Psychiatry (WFSBP) Task Force for the Pharmacological Treatment of Anxiety, Obsessive-Compulsive and Posttraumatic Stress Disorders (published in 2002, revised in 2008). METHOD: A consensus panel of 33 international experts representing 22 countries developed recommendations based on efficacy and acceptability of available treatments. In total, 1007 RCTs for the treatment of these disorders in adults, adolescents, and children with medications, psychotherapy and other non-pharmacological interventions were evaluated, applying the same rigorous methods that are standard for the assessment of medications. RESULT: This paper, Part I, contains recommendations for the treatment of panic disorder/agoraphobia (PDA), generalised anxiety disorder (GAD), social anxiety disorder (SAD), specific phobias, mixed anxiety disorders in children and adolescents, separation anxiety and selective mutism. Selective serotonin reuptake inhibitors (SSRI) and serotonin-norepinephrine reuptake inhibitors (SNRIs) are first-line medications. Cognitive behavioural therapy (CBT) is the first-line psychotherapy for anxiety disorders. The expert panel also made recommendations for patients not responding to standard treatments and recommendations against interventions with insufficient evidence. CONCLUSION: It is the goal of this initiative to provide treatment guidance for these disorders that has validity throughout the world.

World Federation of Societies of Biological Psychiatry (WFSBP) guidelines for treatment of anxiety, obsessive-compulsive and posttraumatic stress disorders - Version 3. Part II: OCD and PTSD.

AIM: This is the third version of the guideline of the World Federation of Societies of Biological Psychiatry (WFSBP) Task Force for the Pharmacological Treatment of Anxiety, Obsessive-Compulsive and Posttraumatic Stress Disorders which was published in 2002 and revised in 2008. METHOD: A consensus panel of 34 international experts representing 22 countries developed recommendations based on efficacy and acceptability of the treatments. In this version, not only medications but also psychotherapies and other non-pharmacological interventions were evaluated, applying the same rigorous methods that are standard for the assessment of medication treatments. RESULT: The present paper (Part II) contains recommendations based on published randomised controlled trials (RCTs) for the treatment of OCD (n = 291) and PTSD (n = 234) in children, adolescents, and adults. The accompanying paper (Part I) contains the recommendations for the treatment of anxiety disorders.For OCD, first-line treatments are selective serotonin reuptake inhibitors (SSRIs) and cognitive behavioural therapy (CBT). Internet-CBT was also superior to active controls. Several second-line medications are available, including clomipramine. For treatment-resistant cases, several options are available, including augmentation of SSRI treatment with antipsychotics and other drugs.Other non-pharmacological treatments, including repetitive transcranial magnetic stimulation (rTMS), deep brain stimulation (DBS) and others were also evaluated.For PTSD, SSRIs and the SNRI venlafaxine are first-line treatments. CBT is the psychotherapy modality with the best body of evidence. For treatment-unresponsive patients, augmentation of SSRI treatment with antipsychotics may be an option. CONCLUSION: OCD and PTSD can be effectively treated with CBT and medications.

Therapeutic effects of Silexan on somatic symptoms and physical health in patients with anxiety disorders: A meta-analysis.

A meta-analysis was performed to examine therapeutic effects of Silexan on somatic symptoms, including insomnia/fatigue, and physical health in patients with anxiety disorders. Five randomized, placebo-controlled trials were included in this analysis: The efficacy of Silexan (80 mg/day) was investigated in patients with subthreshold anxiety disorders (three trials) and in patients with generalized anxiety disorder (two trials). Silexan was superior to placebo in terms of the mean change from baseline in the Hamilton Anxiety Rating Scale (HAMA) subscore somatic anxiety at week 10 with a standardized mean difference of -0.31 [95% Cl: -0.52 to -0.10, p = .004]. Treatment effects of silexan on somatic anxiety were independent of gender and age. Statistically significant differences were also shown for single HAMA items somatic muscular, cardiovascular, respiratory, and genitourinary symptoms, indicating clinical relevance with small to medium effects of Silexan. Similar clinically meaningful effects of Silexan on SF-36 physical health, including reduced bodily pain and improved general health, and on insomnia complaints and fatigue, were demonstrated. In this meta-analysis including all placebo-controlled clinical trials in patients with anxiety disorders to date, statistically significant and clinically meaningful advantages of Silexan over placebo treatment were found in improving somatic symptoms and physical health.

SSRI Treatment Response Prediction in Depression Based on Brain Activation by Emotional Stimuli.

Introduction: The prediction of antidepressant treatment response may improve outcome. Functional magnetic resonance imaging (fMRI) of emotion processing in major depressive disorder (MDD) may reveal regional brain function serving as predictors of response to treatment with selective serotonin reuptake inhibitor (SSRI). Methods: We examined the association between pre-treatment neural activity by means of fMRI during the perception of emotional stimuli in 22 patients with MDD and the treatment outcome after 6 weeks' medication with an SSRI. A whole brain correlation analysis with Beck Depression Inventory (BDI) change between pre- to post-treatment was conducted to identify neural regions associated with treatment response. Results: During the perception of positive stimuli, responders were characterized by more activation in posterior cingulate cortex (PCC), medial prefrontal cortex, and thalamus as well as middle temporal gyrus. During perception of negative stimuli, PCC, and pregenual anterior cingulate cortex showed the highest correlation with treatment response. Furthermore, responders exhibited higher activation to emotional stimuli than to neutral stimuli in all the above-mentioned regions, while non-responders demonstrated an attenuated neural response to emotional compared to neutral stimuli. Conclusion: Our data suggest that the activity of distinct brain regions is correlated with SSRI treatment outcome and may serve as treatment response predictor. While some regions, in which activity was correlated with treatment response, can be assigned to networks that have been implied in the pathophysiology of depression, most of our regions of interest could also be matched to the default mode network (DMN). Higher DMN activity has been associated with increased rumination as well as negative self-referential processing in previous studies. This may suggest our responders to SSRI to be characterized by such dysregulations and that SSRIs might modify the function associated with this network.

Functional connectivity between prefrontal cortex and subgenual cingulate predicts antidepressant effects of ketamine.

Converging evidence suggests that a single sub-anesthetic dose of ketamine can produce strong and rapid antidepressant effects in patients that do not respond to standard treatment. Despite a considerable amount of research investigating ketamine's mechanisms of action, the exact neuronal targets conveying the antidepressant effects have not been identified yet. Preclinical studies suggest that molecular changes induced by ketamine bring forward large-scale network reconfigurations that might relate to ketamine's antidepressant properties. In this prospective two-site study we measured resting state fMRI in 24 depressed patients prior to, and 24 h after a single sub-anesthetic dose of ketamine. We analyzed functional connectivity (FC) at baseline and after ketamine and focused our analysis on baseline FC and FC changes directly linked to symptom reduction in order to identify neuronal targets that predict individual clinical responses to ketamine. Our results show that FC increases after ketamine between right lateral prefrontal cortex (PFC) and subgenual anterior cingulate cortex (sgACC) are positively linked to treatment response. Furthermore, low baseline FC between these regions predicts treatment outcome. We conclude that PFC-sgACC connectivity may represent a promising biomarker with both predictive and explanatory power.

The fear of being laughed at as additional diagnostic criterion in social anxiety disorder and avoidant personality disorder?

Social anxiety disorder (SAD) is the most common anxiety disorder and has considerable negative impact on social functioning, quality of life, and career progression of those affected. Gelotophobia (the fear of being laughed at) shares many similarities and has therefore been proposed as a subtype of SAD. This hypothesis has, however, never been tested in a clinical sample. Thus, the relationship between gelotophobia, SAD and avoidant personality disorder (APD) was investigated by examining a sample of 133 participants (64 psychiatric patients and 69 healthy controls matched for age and sex) using the Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders (4th edition) and an established rating instrument for gelotophobia (GELOPH<15>). As expected, gelotophobia scores and the number of gelotophobic individuals were significantly higher among patients with SAD (n = 22) and APD (n = 12) compared to healthy controls and other psychiatric patients. Furthermore, gelotophobia scores were highest in patients suffering from both SAD and APD. In fact, all patients suffering from both disorders were also suffering from gelotophobia. As explained in the discussion, the observed data did not suggest that gelotophobia is a subtype of SAD. The findings rather imply that the fear of being laughed at is a symptom characteristic for both SAD and APD. Based on that, gelotophobia may prove to be a valuable additional diagnostic criterion for SAD and APD and the present results also contribute to the ongoing debate on the relationship between SAD and APD.

[Managment of the suicidal patient in the out-patient practice]. / Umgang mit dem suizidalen Patienten in der ambulanten Praxis.

Appropriate handling of suicidal tendencies is for certain one of the most important duties within ambulant treatment. As various examples show, occurrence of a suicidal tendency can be chronical as well as acute. Well-known risk factors including current psychopathology and psychodynamics help to identify and assess a suicidal tendency and to take necessary therapeutic options. Some of these can be applied in general, others have to be tailored specifically with respect to the mental disorder in question. Suicide often occurs in an interpersonal context. This fact underlines on one hand the importance and the therapeutic potential of the relationship between the patient and the therapist, on the other hand it results in many cases in a highly stressful situation for the therapist. Significant attention has to be paid to counter transference and its control. Development of an emergency plan and challenges of a "non-suicidal-contract" are discussed. We recommend an agreement with the patient to contact the therapist in case of not feeling able to control his/her own actions. This agreement includes our guarantee of permanent reachability.

[Not Available]. / Die Krankheit Depression kann jeden treffen.

The survey "Datenerhebung zur Depression in der Allgemeinbevölkerung" was conducted from fall 2010 to spring 2011 on several online platforms. The results show that there is a considerable timespan between the appearance of initial symptoms of depression and the first diagnosis of a patient. Intervention at early stages of the disease can reduce a potentially long time of suffering and can lead to the successful treatment of depression. General practitioners play an important role as the link between patient and psychiatrist.

Patterns of heroin, cocaine, and alcohol abuse during long-term methadone maintenance treatment.

Individuals' use of heroin, cocaine, and alcohol during long-term methadone maintenance treatment (MMT) was studied. Prospectively collected data from 103 heroin-addicted individuals who were consecutively admitted for MMT and remained 2 years in treatment were evaluated. The patients were assessed every 6 months with a standardized interview. Three longitudinal patterns of drug abuse were identified. A proportion of patients abstained fully from their particular drug use (26% from heroin, 39% from cocaine, and 19% from alcohol); a proportion (39%, 32%, and 47%, respectively) switched between periods of abuse and nonuse of these drugs; and chronic drug users (34%, 28%, and 33%, respectively) continued use, including periods of daily abuse throughout MMT. Different therapeutic interventions may be needed in patients with different longitudinal patterns of additional substance use during MMT.

Anticonvulsant drugs in the treatment of substance withdrawal.

Although detoxification cannot, in itself, be considered a treatment for addiction, it is one of the most pivotal phases. In order to facilitate entry into recovery and/or rehabilitation programs, a detoxification treatment has to be experienced as easy and safe by the patient. In consideration of the many inconveniences related to standard withdrawal treatments, there is an interest in developing alternative pharmacological strategies. The main rationales for using anticonvulsants in substance-abuse patients are their lack of addiction potential, evidence support a role of kindling mechanisms in withdrawal syndromes and their efficacy in comorbid psychiatric disorders. The available data currently support the utilization of carbamazepine as a treatment for detoxification from benzodiazepines, alcohol and opiates, and as a useful agent to reduce cocaine consumption. The use of valproate is well corroborated for alcohol detoxification and it seems to be a promising treatment for the reduction of cocaine use; however, it has been found to be ineffective against benzodiazepine withdrawal symptoms. Some preliminary data suggest that lamotrigine could be useful in opiate and cocaine dependence. Gabapentin shows potential as a treatment for cocaine dependence, and some case reports have stimulated interest in this agent for alcohol and benzodiazepine detoxification. Due to its particular pharmacological profile, topiramate is one of the most interesting newer anticonvulsants. It has been found to be efficacious in opiate and possibly benzodiazepine detoxification and also has theoretical potential as a preventive therapy.
