The World Federation of Societies of Biological Psychiatry (WFSBP) 2020 guidelines for the pharmacological treatment of paraphilic disorders.

Objectives: The primary aim of these guidelines is to evaluate the role of pharmacological agents in the treatment and management of patients with paraphilic disorders, with a focus on the treatment of adult males. Because such treatments are not delivered in isolation, the role of specific psychotherapeutic interventions is also briefly covered. These guidelines are intended for use in clinical practice by clinicians who diagnose and treat patients, including sexual offenders, with paraphilic disorders. The aim of these guidelines is to bring together different views on the appropriate treatment of paraphilic disorders from experts representing different countries in order to aid physicians in clinical decisions and to improve the quality of care.Methods: An extensive literature search was conducted using the English-language-literature indexed on MEDLINE/PubMed (1990-2018 for SSRIs) (1969-2018 for hormonal treatments), supplemented by other sources, including published reviews.Results: Each treatment recommendation was evaluated and discussed with respect to the strength of evidence for its efficacy, safety, tolerability, and feasibility. The type of medication used depends on the severity of the paraphilic disorder and the respective risk of behaviour endangering others. GnRH analogue treatment constitutes the most relevant treatment for patients with severe paraphilic disorders.Conclusions: An algorithm is proposed with different levels of treatment for different categories of paraphilic disorders accompanied by different risk levels.

Validation of the Change or Stop Testosterone-Lowering Medication (COSTLow) Scale Using the Delphi Method Among Clinical Experts.

Guidelines for pharmacological treatment of patients with paraphilic disorders have been developed by a working group of the World Federation of Societies of Biological Psychiatry (Thibaut et al., 2010 ). With an increasing duration of experience and number of treated patients as well as aging patients, change of or withdrawal from testosterone-lowering medications (TLM) has become an important issue. The current study aimed to assess the quality of a structured professional judgment procedure that helps switching or discontinuing TLM in patients with paraphilic disorders. We used the Delphi method to estimate the quality of 10 factors originally proposed by the authors. A total of 30 experts participated in the first stage; 18 experts participated in the second stage. The experts' assessment resulted in an instrument of 15 factors that can be used to structure the process of changing or discontinuing TLM. These factors can be grouped into five broader categories: age and duration of treatment; therapeutic alliance; psychopathology and risk factors; motivation; and compliance and level of control. The developed COSTLow-R Scale provides an instrument that can be used to structure the process of changing or discontinuing TLM in patients with severe paraphilic disorders.

The World Federation of Societies of Biological Psychiatry (WFSBP) guidelines for the treatment of adolescent sexual offenders with paraphilic disorders.

The primary aim of these guidelines was to evaluate the role of pharmacological agents in the treatment of adolescents with paraphilic disorders who are also sexual offenders or at-risk of sexual offending. Psychotherapeutic and psychosocial treatments were also reviewed. Adolescents with paraphilic disorders specifically present a different therapeutic challenge as compared to adults. In part, the challenge relates to adolescents being in various stages of puberty and development, which may limit the use of certain pharmacological agents due to their potential side effects. In addition, most of the published treatment programmes have used cognitive behavioural interventions, family therapies and psychoeducational interventions. Psychological treatment is predicated in adolescents on the notion that sexually deviant behaviour can be controlled by the offender, and that more adaptive behaviours can be learned. The main purposes of these guidelines are to improve the quality of care and to aid physicians in their clinical decisions. These guidelines brought together different expert views and involved an extensive literature research. Each treatment recommendation was evaluated and discussed with respect to the strength of evidence for efficacy, safety, tolerability and feasibility. An algorithm is proposed for the treatment of paraphilic disorders in adolescent sexual offenders or those who are at risk.

Consensus on guidelines for stereotactic neurosurgery for psychiatric disorders.

BACKGROUND: For patients with psychiatric illnesses remaining refractory to 'standard' therapies, neurosurgical procedures may be considered. Guidelines for safe and ethical conduct of such procedures have previously and independently been proposed by various local and regional expert groups. METHODS: To expand on these earlier documents, representative members of continental and international psychiatric and neurosurgical societies, joined efforts to further elaborate and adopt a pragmatic worldwide set of guidelines. These are intended to address a broad range of neuropsychiatric disorders, brain targets and neurosurgical techniques, taking into account cultural and social heterogeneities of healthcare environments. FINDINGS: The proposed consensus document highlights that, while stereotactic ablative procedures such as cingulotomy and capsulotomy for depression and obsessive-compulsive disorder are considered 'established' in some countries, they still lack level I evidence. Further, it is noted that deep brain stimulation in any brain target hitherto tried, and for any psychiatric or behavioural disorder, still remains at an investigational stage. Researchers are encouraged to design randomised controlled trials, based on scientific and data-driven rationales for disease and brain target selection. Experienced multidisciplinary teams are a mandatory requirement for the safe and ethical conduct of any psychiatric neurosurgery, ensuring documented refractoriness of patients, proper consent procedures that respect patient's capacity and autonomy, multifaceted preoperative as well as postoperative long-term follow-up evaluation, and reporting of effects and side effects for all patients. INTERPRETATION: This consensus document on ethical and scientific conduct of psychiatric surgery worldwide is designed to enhance patient safety.

Psychomotor function and response inhibition in chronic fatigue syndrome.

Most research points to cognitive slowing in chronic fatigue syndrome (CFS), although there have been negative reports. The present study is one of few that examines fine motor processing and the inhibition of automatic responses in a well-characterised CFS population. A total of 35 female CFS patients without current major depression and 25 female controls performed two computerised figure-copying tasks. The cognitive and fine motor processing of visual-spatial information was measured by recording reaction time (RT) and movement time (MT), respectively. The inhibition of automatic responses was assessed by introducing 'conflicting patterns' (i.e., patterns that were difficult to draw from the preferred left to right). A multivariate general linear model was adopted for the statistical analysis of the movement recordings. As a result, CFS was significantly associated with longer RT and MT in the pooled and in the task-specific analyses. However, there was no interaction between disease status and conflicting character of the patterns. In conclusion, these performance data on the figure-copying tasks provide confirmatory evidence for psychomotor slowing in CFS, but not for a disturbed inhibition of automatic responses. Computerised figure-copying tasks may be promising tools for use in neurobiological research and clinical trials in CFS.

The World Federation of Societies of Biological Psychiatry (WFSBP) guidelines for the biological treatment of paraphilias.

OBJECTIVES: The primary aim of these guidelines was to evaluate the role of pharmacological agents in the treatment and management of paraphilia, with a focus on the treatment of adults males. Because such treatments are not delivered in isolation, the role of specific psychosocial and psychotherapeutic interventions was also briefly covered. These guidelines are intended for use in clinical practice by clinicians who diagnose and treat patients with paraphilia. The aim of these guidelines is to improve the quality of care and to aid physicians in clinical decisions. METHODS: The aim of these guidelines was to bring together different views on the appropriate treatment of paraphilias from experts representing different continents. To achieve this aim, an extensive literature search was conducted using the English language literature indexed on MEDLINE/PubMed (1990-2009 for SSRIs) (1969-2009 for antiandrogen treatments), supplemented by other sources, including published reviews. RESULTS: Each treatment recommendation was evaluated and discussed with respect to the strength of evidence for its efficacy, safety, tolerability and feasibility. CONCLUSIONS: An algorithm was proposed with six levels of treatment for different categories of paraphilias.

Use of the Temperament and Character Inventory (TCI) for assessment of personality in chronic fatigue syndrome.

BACKGROUND: Chronic fatigue syndrome (CFS) is characterized by severe and prolonged fatigue, along with a set of nonspecific symptoms and signs, such as sore throat, muscle pain, headaches, and difficulties with concentration or memory. OBJECTIVE: The study examined whether CFS is associated with specific dimensions of Cloninger's psychobiological model of personality. METHOD: Personality profiles were compared between 38 CFS patients and 42 control subjects by means of the Temperament and Character Inventory (TCI). RESULTS: The CFS group showed significantly higher scores on Harm-Avoidance and Persistence. CONCLUSION: The current study shows a significant association between specific personality characteristics and CFS. These personality traits may be implicated in the onset and/or perpetuation of CFS and may be a productive focus for psychotherapy.

Chronic fatigue syndrome and DSM-IV personality disorders.

OBJECTIVE: Personality is an important factor in the research of the chronic fatigue syndrome (CFS). Although some studies report a high rate of personality disorders--around the 40% level--in samples of patients with CFS, the generalizability of these findings can be questioned. The present study evaluates the prevalence of Diagnostic and Statistical Manual for Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR) personality disorders in a sample of female CFS patients and in two control groups. METHOD: The ADP-IV questionnaire (Assessment of DSM Personality Disorders IV) was used to assess the DSM-IV-TR personality disorders at a dimensional and categorical level in a sample of 50 female CFS patients and in two matched control samples of Flemish civilians (n=50) and psychiatric patients (n=50). RESULTS: The results indicate a striking lack of statistical significant differences between the CFS sample and the Flemish control group at the level of dimensional Trait scores, number of criteria, and prevalence rates of personality disorder diagnoses. Unsurprisingly, higher scores at these levels were obtained within the psychiatric sample. The prevalence of an Axis II disorder was 12% in the Flemish and CFS samples, whereas the psychiatric sample obtained a prevalence of 54%. CONCLUSION: The prominent absence of any significant difference in personality disorder characteristics between the female Flemish general population and the CFS samples seems to suggest only a minor etiological role for personality pathology, as defined by the DSM-IV Axis II, within CFS.

Long-term electrical capsular stimulation in patients with obsessive-compulsive disorder.

OBJECTIVE: Because of the irreversibility of lesioning procedures and their possible side effects, we studied the efficacy of replacing bilateral anterior capsulotomy with chronic electrical capsular stimulation in patients with severe, long-standing, treatment-resistant obsessive-compulsive disorder. METHODS: We stereotactically implanted quadripolar electrodes in both anterior limbs of the internal capsules into six patients with severe obsessive-compulsive disorder. Psychiatrists and psychologists performed a double-blind clinical assessment. A blinded random crossover design was used to assess four of those patients, who underwent continuous stimulation thereafter. RESULTS: The psychiatrist-rated Yale-Brown Obsessive Compulsive Scale score was lower in the stimulation-on condition (mean, 19.8 +/- 8.0) than in the postoperative stimulator-off condition (mean, 32.3 +/- 3.9), and this stimulation-induced effect was maintained for at least 21 months after surgery. The Clinical Global Severity score decreased from 5 (severe; standard deviation, 0) in the stimulation-off condition to 3.3 (moderate to moderate-severe; standard deviation, 0.96) in the stimulation-on condition. The Clinical Global Improvement scores were unchanged in one patient and much improved in the other three during stimulation. During the stimulation-off period, symptom severity approached baseline levels in the four patients. Bilateral stimulation led to increased signal on functional magnetic resonance imaging studies, especially in the pons. Digital subtraction analysis of preoperative [(18)F]2-fluoro-2-deoxy-d-glucose positron emission tomographic scans and positron emission tomographic scans obtained after 3 months of stimulation showed decreased frontal metabolism during stimulation. CONCLUSION: These observations indicate that capsular stimulation reduces core symptoms 21 months after surgery in patients with severe, long-standing, treatment-refractory obsessive-compulsive disorder. The stimulation elicited changes in regional brain activity as measured by functional magnetic resonance imaging and positron emission tomography.

Single nucleotide polymorphism analysis of corticotropin-releasing factor-binding protein gene in recurrent major depressive disorder.

Corticotropin-releasing factor-binding protein (CRF-BP) regulates the availability of free CRF and is a functional candidate gene for affective disorders. Previous research showed an association between polymorphisms in the CRF-BP gene and recurrent major depression (MDD) in a Swedish sample. The purpose of the current study was to re-evaluate the previous findings in an extended Swedish sample and in an independent Belgian sample of patients with recurrent MDD and in control samples. In total, 317 patients and 696 control individuals were included. Five single nucleotide polymorphisms (SNPs) and a deletion polymorphism in the CRF-BP gene were genotyped and the haplotype block structure of the gene was assessed. In the extended Swedish population, there was a trend towards an association between two SNPs and MDD. The subsequent gender analysis showed significant associations of three SNPs (CRF-BPs2 T; CRF-BPs11 T and CRF-BPs12 C) and haplotype G_T_C_T_C with MDD in Swedish males. However, these findings did not withstand correction for multiple testing and there were no significant SNP or haplotype associations in the Belgian MDD sample. In conclusion, this study does not provide confirmatory evidence for a role of the CRF-BP gene in the vulnerability for MDD in general. The association between genetic CRF-BP variants and MDD may be sexually dimorphic, but this issue requires further investigation in a larger sample.

Hypothalamic-pituitary-adrenal axis function in chronic fatigue syndrome.

There is evidence for a hypofunction of the hypothalamic-pituitary-adrenal (HPA) axis in a proportion of the patients with chronic fatigue syndrome (CFS), despite the negative studies and methodological difficulties. In this review, we focus on challenge studies and on the role of the HPA axis in the pathogenesis of CFS. Mild hypocortisolism, blunted adrenocorticotropin response to stressors and enhanced negative feedback sensitivity to glucocorticoids are the main findings. Several underlying mechanisms have been proposed. Currently, it is a matter of debate whether these disturbances have a primary role in the pathogenesis of CFS. However, even if the HPA axis dysfunctions are secondary to other factors, they are probably a relevant factor in symptom propagation in CFS.

Lower omega-3 polyunsaturated fatty acids and lower docosahexaenoic acid in men with pedophilia.

BACKGROUND: Previous studies have suggested that abnormalities in plasma phospholipid fatty acids may play a role in aggressive behavior. Recently, it was suggested that a dysfunctional serotonergic turnover in the brain may be involved in the etiopathology of pedophilia. Depletion of n-3 polyunsaturated fatty acids (PUFA) may cause alterations in the serotonergic system that may be related to pedophilia and aggression. METHODS: This study examines the serum phospholipid n-3 and n-6 PUFA fractions in pedophilia. Twenty-seven pedophilic men and eighteen healthy volunteers participated in this study. RESULTS: In pedophilia there was a significant depletion of the C22:6n-3 (docosahexaenoic acid, DHA), total n-3 fractions and an increase in the total n-6/n-3 and C20:4n-6/C20:5n-3 (arachidonic acid/eicosapentaenoic acid) ratios. Using the NEO Personality Inventory, lower DHA in pedophiles is related to more impulsiveness and lower agreeableness (trust, altruism, straightforwardness, compliance) and conscientiousness (self-discipline). CONCLUSIONS: The results of this study suggest that a depletion of the serum phospholipid n-3 higher unsaturated fatty acids (HUFAs) and, in particular, of DHA may take part in the pathophysiology of pedophilia. One hypothesis is that a depletion of n-3 HUFAs and DHA may cause alterations in the serotonergic turnover, which are related to impulse discontrol and aggression-hostility, behaviors which are associated with pedophilia.

A biopsychosocial model as a guide for psychoeducation and treatment of depression.

Effective treatment of severe or chronic unipolar depression requires the combination of pharmacological and psychotherapeutic interventions, and demands a theoretical paradigm integrating biological and psychosocial aspects of depression. Supported by recent research, we propose in our article a biopsychosocial diathesis-stress model of depression. Its basic aim is psychoeducational: to provide therapists, patients, and their environment a constructive conceptual framework to understand depressive complaints, vulnerability, and stress. The core of the model consists of the concept of psychobiological vulnerability, which is determined by risk factors-of a biogenetic, psychological, somatic, and societal nature-and by protective factors. Life events with an idiosyncratic, stress-inducing value interact with this vulnerability, triggering severe or chronic distress that affects the individual's resilience and leads to symptoms of depression. The pathogenesis of depression is symbolized by a negative downward loop, in which interactions among symptoms, vulnerability, and stressors drive the patient toward a depressive condition. Moreover, experiencing recurrent depression influences psychobiological vulnerability, the occurrence of stressors, and tremendously increases the risk of further relapse. The model stresses the self-evident integration of biological and psychological therapeutic interventions that need to focus on symptom reduction and on relapse prevention. Moreover, it offers the patient and therapist a psychoeducational context in which the individual's vulnerability and depressive symptoms can be treated. Finally, applications of the depression model as a therapeutic approach to severe depression in the phases of remoralization, symptom reduction, and relapse prevention are presented.

Combined dexamethasone/CRF test in remitted outpatients with recurrent major depressive disorder.

BACKGROUND: Hyperactivity of the hypothalamic-pituitary-adrenal (HPA) axis is a prominent neurobiological finding during a major depressive episode, reflecting a state dependent factor. An issue under investigation is whether the dysfunction of the HPA axis has also a role to play as a state-independent or trait factor for major depressive disorder (MDD). In relation to this, it is important to examine HPA axis function in patients who are clinically remitted from depression. METHODS: Twenty-three remitted outpatients with recurrent MDD and 23 age- and gender-matched control individuals without a history of MDD participated in the sensitive combined dexamethasone/corticotropin-releasing factor (DEX/CRF) test. RESULTS: Free salivary cortisol responses were not significantly different between the two groups, although three patients (13%) displayed extremely elevated cortisol responses after CRF. LIMITATIONS: Limited sample size. All but one patient were under treatment with an antidepressant. CONCLUSIONS: This study shows no evidence for a disturbed DEX/CRF test as a state-independent factor in recurrent MDD on a group level. However, MDD is a complex and heterogenic disorder. Probably, there is a subgroup of patients who show a disturbed DEX/CRF test due to an inherited and/or acquired predisposition or as a biological scar after previous depressive episodes.

Metabolic imaging of anterior capsular stimulation in refractory obsessive-compulsive disorder: a key role for the subgenual anterior cingulate and ventral striatum.

UNLABELLED: High-frequency anterior capsular stimulation is a new, promising, and reversible neuromodulatory treatment in the research stage for patients with refractory obsessive-compulsive disorder (OCD). The mechanism of action is unknown but hypothesized to be secondary to interruption of the corticothalamostriatocortical circuit. METHODS: (18)F-FDG PET was performed on 6 consecutive OCD patients preoperatively and after stimulation. The results were compared with those of 20 age- and sex-matched healthy volunteers by using both a standardized volume-of-interest-based approach for subcortical areas and statistical parametric mapping. Correlations were investigated with Yale-Brown Obsessive Compulsive Scale scores (Y-BOCS) and Hamilton Depression Rating Scale scores (HAM-D). RESULTS: Chronic anterior capsular electrostimulation resulted in a further decrease of prefrontal metabolic activity, especially in the subgenual anterior cingulate (P < 0.001). Correlation analysis demonstrated that decreases in Y-BOCS and HAM-D with anterior capsular electrostimulation were inversely related to the metabolic activity changes in the left ventral striatum, left amygdala, and left hippocampus (P < 0.01). Preoperative resting metabolic activity in the subgenual anterior cingulate was predictive of therapeutic response (P = 0.001). CONCLUSION: These observations provide evidence that the subgenual anterior cingulate and ventral striatum have a key role in the neuronal circuitry involved in the pathophysiology of OCD with associated major depression and in the neuromodulatory mechanism of anterior capsular stimulation.

The use of atypical antipsychotics in the treatment of catatonia.

PURPOSE: Evidence indicates that classical antipsychotics may aggravate non-malignant and malignant catatonia (MC). Atypical antipsychotics are less likely to cause movement disorders than classical antipsychotics and they are being frequently prescribed in disorders that can be associated with catatonia. Therefore, the important question that arises is whether atypical antipsychotics have a role to play in the treatment of catatonia. MATERIALS AND METHODS: A Medline search was performed to locate papers on the use of atypical antipsychotics in catatonia published between 1970 and 31st December 2004. RESULTS: The literature on the use of atypical antipsychotics in catatonia consists of case reports and retrospective studies. In most cases of non-MC a reduction of the catatonic symptoms is reported upon treatment with atypical antipsychotics. Cases of MC relate mainly to the neuroleptic malignant syndrome (NMS), which is considered as an iatrogenic stuporous variant of MC caused by antipsychotics. CONCLUSION: There are indications that atypical antipsychotics may be useful in non-MC. As a consequence, one should not only focus on the possible extrapyramidal and autonomic side effects of these drugs, but also on the possible beneficial effects on certain brain functions and on the catatonic symptomatology. However, randomized controlled trials are needed to evaluate the effect of these drugs, and caution is advisable, since cases of NMS have been linked to treatment with atypical antipsychotics. There is no evidence to prescribe atypical antipsychotics in MC.

The ADP-IV questionnaire: differential validity and concordance with the semi-structured interview.

The Assessment of DSM-IV Personality Disorders questionnaire (ADP-IV) is a self-report measure of the DSM-IV Axis II personality disorders (PDs). The ADP-IV assesses for each DSM-IV criterion its typicality as well as the accompanying distress and impairment. This study investigates two important aspects of the construct validity of the ADP-IV: (a) the differential validity (i.e., the ability to differentiate between a sample of the general Flemish population ( n = 659) and a sample of psychiatric inpatients ( n = 487) with a high prevalence of clinical PD diagnoses, and patients with and without a PD in the psychiatric sample; (b) the convergent validity with the SCID-II semi-structured interview in a population of psychiatric inpatients ( n = 59). The results indicate a good differential validity: the dimensional scales and the categorical measures discriminated well between both groups and between patients with and without a PD diagnosis in the psychiatric sample. Concerning the concordance with the SCID-II, a decent level of agreement is exemplified by a correlation of.67 between the dimensional total scores of both instruments and by kappa coefficients for an "any" Axis II diagnosis at the.50 level. In conclusion, the results indicate that the ADP-IV is an efficient method for assessing PD in dimensional and categorical ways.
