Differential pharmacological treatment of paraphilias and sex offenders

The impact of testosterone-lowering medication on recidivism in individuals convicted of sexual offenses

INTRODUCTION

Treatment of individuals who have committed sexual offences with Testosterone-Lowering Medication (TLM) is a comparatively intrusive kind of intervention, which regularly takes place in coercive contexts. Thus, the question of efficacy, but also the question of who should be treated, when and for how long, are of great importance.

METHODS

Recidivism rates of TLM-treated high-risk individuals (+TLM; n = 54) were compared with high-risk individuals treated with psychotherapy only in the same forensic outpatient clinic (-TLM; n = 79).

RESULTS

Group differences suggested a higher initial risk of + TLM (e.g. higher ris-assessment, previous convictions). Despite the increased risk, after an average time at risk of six years, +TLM recidivated significantly less often and significantly later than - TLM (27.8% vs. 51.9%). Such an effect was also found for violent (1.9% vs. 15.2%), but not for sexual (5.6% vs. 10.1%) and serious recidivism (5.6% vs. 10.1%), which could be explained partly by the small number of cases. In the course of treatment, TLM proved to be a significant variable for a positive process, whereas a high risk-assessment score indicated a rather negative course. In total, n = 19 individuals had stopped their TLM treatment, of these 31.6% recidivated.

CONCLUSION

The results support the efficacy of TLM, particularly in the group of high-risk offenders.

Survey on the Prescription Patterns of Pharmacological Agents in Individuals Who Have Committed Sexual Offenses During Forensic Outpatient Treatment in Germany: How Many Discontinue Testosterone Lowering Medication Under Parole?

BACKGROUND

The number of individuals who sexually offended, and who are continued to be treated with pharmacological agents to reduce sex drive after their release from prison or forensic psychiatry, are not known. Furthermore, figures on the number of those who stop their sexdrive supressing antiandrogen treatment in the outpatient setting are unknown as well. This is of central importance though as it might be associated with an increased risk of recidivism.

AIM

To assess prescription patterns as well as adherence to pharmacological treatment in outpatient clinics in Germany for individuals who have sexually offended and were released from prison or forensic psychiatric hospital.

METHODS

A self-constructed online survey assessing the pharmacological treatment modalities was sent by e-mail to n = 103 forensic outpatient clinics in Germany. Thirty-three (32.0%) completed the questionnaire and reported about 834 patients.

OUTCOMES

Prevalence of the use of different pharmacological agents in the treatment of individuals convicted for sexual offenses as well as the number of patients who have discontinued testosterone-lowering medication (TLM).

RESULTS

Among all institutions, 22.4% (n = 187) of individuals received pharmacological treatment, with 40.1% receiving gonadotropin-releasing-hormone-agonists, 26.2% antipsychotics, 24.6% selective serotonin reuptake inhibitors, 6.4% cyproterone acetate, and 2.7% a combination of gonadotropin-releasing-hormone-agonists and cyproterone acetate. A significant positive correlation was found between the number of patients released from a forensic-psychiatric hospital and the number of patients treated with TLM. Within 1 year 8.6% (n = 16) stopped their TLM during or at the end of the supervision period, most of them against treatment providers advice.

CLINICAL IMPLICATIONS

Substantial regional differences indicate uncertainties regarding the prescription of pharmacological agents for outpatients who have committed sexual offences in Germany. The discontinuiation of TLM within the first year of treatment against treatment providers advise in a substantial proportion of patients could be associated with a serious risk for reoffending.

STRENGTHS & LIMITATIONS

The present survey captures prevalences of the pharmacotherapy in forensic aftercare facilities for individuals who have offended sexually, and is the first to record the number of discontinuations. This is a cross-sectional survey covering only 1 country, but includes a large number of individuals.

CONCLUSION

Even though the number of treated individuals has increased in prisons, the majority of pharmacological treatment is still provided by forensic hospitals, which then translates into the outpatient setting. The number of those who stop taking such medication is a highly relevant topic for both forensic treatment providers and legal decision makers Sauter J, Rettenberger M, Briken P, et al.

Testosterone-Lowering Medication and Its Association With Recidivism Risk in Individuals Convicted of Sexual Offenses

For a particular subgroup of individuals with severe paraphilic disorders and a high risk of sexual recidivism, the combination of sex drive-reducing medications and psychotherapy is a promising treatment approach. The present quasi-experimental study aims at comparing differences in clinical characteristics and dynamic risk factors between persons receiving (+TLM, n = 38) versus not receiving (-TLM, n = 22) testosterone-lowering medications (TLMs). Individuals receiving TLM were more frequently diagnosed with paraphilic disorders. Neither the criminal history nor average risk scores differed between the two groups. In the +TLM, Stable-2007 scores showed a stronger decrease after TLM treatment was started. This accounted especially for the general and sexual self-regulation subscales. Individual variations in risk, however, were not predicted by TLM but were significantly related to treatment duration and Psychopathy Checklist-Revised (PCL-R) Factor I. Paraphilic patients with problems in self-regulatory abilities seem to profit most from pharmacological sex drive-reducing treatment. Furthermore, therapists seem to underestimate deviant sexual fantasies in medicated patients.

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.

The Use of Leuprolide Acetate in the Management of High-Risk Sex Offenders

The present study investigates whether leuprolide acetate (Lupron) adds to the efficacy of traditional sex offender treatment. A group of sex offenders receiving both Lupron and cognitive behavioral therapy (CBT; n = 25) were compared with a group of sex offenders receiving only CBT (n = 22). Treated subjects were compared with norms available with reference to the Static-99R, as well as compared with a sample of untreated, nonsexual violent offenders (n = 81), to provide baseline data regarding risk of violent recidivism. Results indicated that subjects receiving Lupron were at significantly higher risk of recidivism and significantly more likely to be diagnosed with a paraphilia than subjects receiving only CBT, a priori. Both treated groups of sexual offenders recidivated at substantially lower rates than predicted by the Static-99R. Currently, this study represents the only, long-term outcome study on Lupron administration using officially recorded recidivism as the primary dependent measure.

Monitoring urinary testosterone and epitestosterone levels, and their ratio, in Korean chemical castration subjects using liquid chromatography–tandem mass spectrometry

In Europe, chemical castration has been adopted as a treatment for paraphilia since the 1930s. Among the various chemical castration agents, luteinizing hormone-releasing hormone (LHRH) agonists are now used widely because of their effectiveness and safety. In South Korea, a legislation of chemical castration to control the sexual impulses of sexual offenders was enforced in July 2011. Most of these subjects are treated with leuprorelin acetate, an LHRH agonist, for chemical castration. Despite this, there are few studies that address the long-term influence of LHRH agonists on testosterone (T) and epitestosterone (E) levels in chemical castration subjects. In order to analyze the urinary levels of T in chemical castration subjects, whose T levels are extremely low, we developed and validated an analytical method for the detection of both T and E in human urine using a liquid chromatography-tandem mass spectrometry (LC–MS/MS) system. The urine samples were hydrolyzed, extracted, and analyzed by LC–MS/MS with electrospray ionization in the positive-ion mode. The limits of detection were 0.02 ng/mL and the limits of quantitation were 0.05 ng/mL, which provided great sensitivity. The established method was applied to urine samples from chemical castration subjects and healthy male volunteers. The chemical castration subjects showed significantly lower urinary T levels than the control subjects. In addition, the urinary E levels were also lower in the chemical castration subjects; however, the T/E ratios were constant and did not show a notable decrease because of the simultaneous decrease in both urinary T and E. The urinary T levels and T/E ratio did not exceed the doping control criteria for exogenous T ingestion for any subject. This study shows the trend of urinary T and E levels in long-term treated chemical castration subjects by establishing a highly sensitive LC–MS/MS method, that provides useful information for monitoring chemical castration.

The use of cyproterone acetate in a forensic psychiatric cohort of male sex offenders and its associations with sexual activity and sexual functioning

BACKGROUND

Cyproterone acetate (CPA) is a steroidal anti-androgenic medication used in the field of psychiatry for the treatment of paraphilic disorders, hypersexuality, and inappropriate sexual behaviour which may be present in patients with disorders such as mild and major neurocognitive disorders. In the forensic psychiatric population, it is prescribed for these indications especially for patients with a history of committing a sexual offence or who are at moderate to high risk of recidivism.

OBJECTIVES

To investigate the use of CPA in a forensic psychiatric cohort of male sex offenders and its associations with sexual activity and sexual functioning.

METHODS

Seventy-six forensic psychiatric patients from Weskoppies Hospital in Pretoria, South Africa, participated in the study which measured their sexual functioning. A specifically designed questionnaire was used to capture relevant background information. The use of CPA was studied. The Changes in Sexual Functioning Questionnaire, Male Clinical Version (CSFQ-M-C) was used to measure sexual functioning of participants. The CSFQ-M-C scores, and those of all its subscales, of participants on CPA were compared to those not on the drug. Relevant statistical analyses were performed.

RESULTS

Thirteen out of the 76 participants were being treated with CPA (17.11%). In total, 53.85% of the participants on CPA and 65.08% not on CPA had scores indicating the presence of sexual dysfunction. The total CSFQ-M-C scores for participants on CPA (mean = 40.54; median = 42) were not statistically significantly lower than those not on the drug (mean = 41.22; median = 41). More notable is that the use of CPA in this population was associated with lower levels of desire, frequency of and pleasure from sexual activity. There was an association between having intellectual disability and being treated with CPA.

CONCLUSION

That all the participants were being treated with psychotropic medication could account for the high percentage of sexual dysfunction in any or all areas of sexual functioning and contribute to the small difference in CSFQ-M-C scores between the two groups. Only a tentative conclusion can be made that CPA may be more effective in decreasing levels of desire, frequency and pleasure related to sexual activity than other areas of sexual functioning. The indication for the use of CPA in this population should be assessed clinically according to patient circumstances and risk assessment.

The Biological Treatment of Paraphilic Disorders: an Updated Review

Paraphilic disorders are characterized by atypical sexual interests, fantasies, and behaviors that are subjectively distressing to patients or pose a risk of harm to others. By their very nature, some paraphilic disorders may predispose an individual to commit sexual offenses. The biological treatment of paraphilic disorders, then, is of paramount importance for psychiatry and society at large. Three categories of pharmacologic agents commonly used to treat paraphilic disorders are selective serotonin reuptake inhibitors, synthetic steroidal analogs, and gonadotropin-releasing hormone analogs. Each medication uses a different mechanism of action and has different effects on the physiological and psychological features of paraphilic disorders. In general, these medications have limited high-quality research to support their use. Despite this, some authors have proposed treatment algorithms for individuals with paraphilic disorders of varying severity. These guidelines offer clinicians potentially useful, rational approaches to assessing treatment need in individuals with paraphilic disorders. Recent neuroimaging research suggests that functional magnetic resonance imaging may offer further promise in effectively assessing paraphilic disorders to help direct treatment options.

Pedophilic brain potential responses to adult erotic stimuli

Cognitive mechanisms associated with the relative lack of sexual interest in adults by pedophiles are poorly understood and may benefit from investigations examining how the brain processes adult erotic stimuli. The current study used event-related brain potentials (ERP) to investigate the time course of the explicit processing of erotic, emotional, and neutral pictures in 22 pedophilic patients and 22 healthy controls. Consistent with previous studies, early latency anterior ERP components were highly selective for erotic pictures. Although the ERPs elicited by emotional stimuli were similar in patients and controls, an early frontal positive (P2) component starting as early as 185 ms was significantly attenuated and slow to onset in pedophilia, and correlated with a clinical measure of cognitive distortions. Failure of rapid attentional capture by erotic stimuli suggests a relative reduction in early processing in pedophilic patients which may be associated with relatively diminished sexual interest in adults.

Mental illness and sexual offending

Transinstitutionalization (ie, the criminalization of those with mental illness) is relevant to individuals committing sexual offenses. Mental illness can affect the treatment and risk management of individuals committing sexual offenses. In this article the current literature on mentally disordered sexual offenders is described, including how psychosis, mood disorders, anxiety disorders, attention-deficit/hyperactivity disorder, and dementing disorders may affect treatment and management.

Unrecognized kinetics of serum testosterone: impact on short-term androgen deprivation therapy for prostate cancer

PURPOSE

To evaluate the kinetics of serum testosterone (T) recovery following short-term androgen deprivation therapy (ADT), as the understanding thereof is essential for the proper management of prostate cancer (PCa), especially intermittent ADT.

MATERIALS AND METHODS

This prospective analysis included male sex offenders who voluntarily received leuprolide acetate in order to alleviate sexual aberrance. Thirty-three and 25 patients who received 3 and 6 months of ADT were assigned to Group A and Group B, respectively. Serum T levels were obtained every week during the on-cycle period, then monthly during the off-cycle period for at least 12 months.

RESULTS

The kinetics of serum T during the on-cycle period were similar in both groups. After flare reaction at week 2, a nadir of 0.45±0.29 ng/mL was achieved. In Group A, an abrupt rebound-upsurge was observed during the first 2 month off-cycle period, which surpassed the baseline level and reached a plateau level of 8.74±2.11 ng/mL during the flare (p<0.001). This upsurge was followed by a gradual decline back to baseline over the following 10 months. In Group B, a gradual increase was observed, and a baseline level of 7.26±1.73 ng/mL was reached at 5 months. Thereafter, an ongoing upsurge that surpassed baseline levels was observed until 12 months (8.81±1.92 ng/mL; p=0.002).

CONCLUSION

The kinetics of serum T recovery during the off-cycle period varied according to the duration of ADT. Serum T should be monitored beyond normalization, as an excessive rebound may improve quality-of-life, but hamper the treatment efficacy of PCa.

Pharmacologic treatment of sex offenders with paraphilic disorder

Sexual offending is both a social and a public health issue. Evidence demonstrates that a combination of pharmacological and psychotherapeutic approaches may reduce or even eliminate deviant sexual behavior in sex offenders with paraphilic disorders. In this article, we will review pharmacological treatment options for sex offenders with paraphilias. Both serotonin selective reuptake inhibitors (SSRIs) and antiandrogen treatments have been used with reported success in decreasing recidivism. SSRIs have been used in mild types of paraphilias and juvenile paraphilias. Antiandrogen treatments seem to be effective in severe sex offenders with paraphilic disorders in order to reduce victimization. Combined pharmacological and psychotherapeutic treatment is associated with better efficacy. Imaging studies may improve the knowledge of paraphilic disorders and the mechanisms of action of current treatments. In spite of existing evidence, there is a need for independent, large-scale and good quality studies assessing the long-term efficacy and tolerance of treatments.

The management of sex offenders: perspectives for psychiatry

In the effort to identify and manage sex offenders, the differences between legal and medical/psychiatric terminology and approaches are readily apparent. This article discusses the different definitions and approaches of the two fields and considers both the behaviors that create risk to others and the strategies for reducing that risk. Particular attention is paid to the subcategory of paraphilic sex offenders. Treatment goals, modalities, and efficacies are discussed, as are evolving legal strategies for risk control and the need for interaction between law and medicine/psychiatry in order to accomplish common goals of risk management.

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.

Pharmacology of sexually compulsive behavior

In a meta-analysis on controlled outcomes evaluations of 22,000 sex offenders, Losel and Schmucker found 80 comparisons between treatment and control groups. The recidivism rate averaged 19% in treated groups, and 27% in controls. Most other reviews reported a lower rate of sexual recidivism in treated sexual offenders. Of 2039 citations in this study (including literature in five languages), 60 studies held independent comparisons. Problematic issues included the control groups; various hormonal, surgical, cognitive behavioral, and psychotherapeutic treatments; and sample sizes. In the 80 studies compared after the year 2000, 32% were reported after 2000, 45% originated in the United States, 45% were reported in journals, and 36% were unpublished. Treatment characteristics showed a significant lack of pharmacologic treatment (7.5%), whereas use cognitive and classical behavioral therapy was 64%. In 68% of the studies, no information was available on the integrity of the treatment implementation; 36% of the treatment settings were outpatient only, 31% were prison settings, and 12% were mixed settings (prison, hospital, and outpatient). Integrating research interpretations is complicated by the heterogeneity of sex offenders, with only 56% being adult men and 17.5% adolescents. Offense types reported included 74% child molestation, 48% incest, and 30% exhibitionism. Pedophilia was not singled out. Follow-up periods varied from 12 months to greater than 84 months. The definition of recidivism ran the gamut from arrest (24%), conviction (30%), charges (19%), and no indication (16%). Results were difficult to interpret because of the methodological problems with this type of study. Overall, a positive outcome was noted with sex offender treatment. Cognitive-behavioral and hormonal treatment were the most promising. Voluntary treatment led to a slightly better outcome than mandatory participation. When accounting for a low base rate of sexual recidivism, the reduction was 37%, which included psychological and medical modes of treatment. Which treatments will reduce recidivism rates in sex offenders is extremely difficult to conclude. Some treatment effects are determined from small studies; however, recidivism rates may be based on different criteria. Larger studies tend to be published more frequently than small studies, negative results may be less likely to be reported in published studies, and differences in mandatory versus voluntary treatment may occur. Clearly more high-quality outcome studies are needed to determine which treatments work best for which individuals. One size is unlikely to fit all. However, pharmacologic intervention, although not always the perfect choice, has improved and will continue to advance the treatment of paraphilic, nonparaphilic, and compulsive sexual behaviors.

The Oregon depo-Provera program: a five-year follow-up

In 1999, the Oregon State Legislature, concerned about the risk certain sexual offenders might pose to their communities upon release from prison, enacted House Bill 2500. This bill required selected offenders to be evaluated prior to their release to determine whether medical treatment with medroxyprogesterone acetate (MPA), also known by its trade name of depo-Provera, was indicated to reduce their risk. The present study reviewed the first 275 men to be evaluated under this program from the years 2000 through 2004. Data were collected on diagnoses and outcome on three groups: men judged to need MPA who eventually went on to actually receive it; men recommended to receive MPA who, for a variety of reasons, did not receive the medication; and men deemed not to need MPA. Outcome measures included recidivism data, including reoffenses, parole violations, and reincarcerations, and whether these were sexual in nature. Data were also collected on employment and whether supervising officers believed the men in each group were doing well. Significant differences emerged among these three groups, with men actually receiving depo-Provera committing no new sexual offenses and also committing fewer overall offenses and violations compared to the other two groups. In addition, almost one third of men judged to need medication but who did not receive it committed a new offense and almost 60% of these were sexual in nature. While generalizations from these types of retrospective and partially subjective findings are inherently limited, the present study lends credence to the belief that, in selected offenders, anti-androgenic medication can be a valuable, if time-limited, addition to a cognitive and behavioral treatment program. Suggestions for more practical and far-reaching implementation of this adjunctive approach are offered.

Legislation in Victoria on sexual offenders: issues for health professionals

New legislation passed in Victoria (the Serious Sex Offenders Monitoring Act 2005) extends the role of doctors in managing and treating sex offenders. This legislation is not based on a solid understanding of the research evidence on treatment of sex offenders or on their risk of reoffending. The legislation creates ethical and professional dilemmas for health professionals through the conflation of legal control of offenders with the medical management of disorders of sexual preference. There is a critical need for research and funding in this area, rather than ever more oppressive laws, if governments are to be serious about treating sex offenders, rather than simply incarcerating them.
