Evolution of sexual functioning of men through treated and untreated depression.

OBJECTIVES: Depression as well as a treatment by antidepressant are factors that may interfere with sexuality. Due to this complex relationship between depression, antidepressant and sexuality, it is difficult to incontestably establish the exclusive accountability of a treatment or of a psychiatric disorder on sexual dysfunctions. The main purpose of the SADD (for Sexuality, Anti-Depressant and Depression) study is to evaluate sexual dysfunctions in depressed men treated with antidepressant or not. METHODS: Participants of this transversal, observational study were men aged over 18 years old, suffering from unipolar major depressive disorder and treated by a psychiatrist, with or without antidepressant. Assessment of sexual functioning through three times: euthymia (before depression), untreated depression and treated depression if applicable was performed based on the ASEX scale. RESULTS: Seventy patients were included. Eight percent of euthymic patients presented a sexual dysfunction (average score on the ASEX=12.4) whereas 56% of untreated patients presented a sexual dysfunction (average total score on the ASEX=17.7) and 62% (34/55) of patients treated with antidepressant (average total score on ASEX=18.5) (P<0.001). Sexual functioning of men receiving treatment is not significantly different to that among men not receiving any antidepressant, even if patients treated with antidepressant reported that they had a better mood than those untreated. CONCLUSIONS: Our results reveal a high prevalence of sexual dysfunction within the framework of major depressive disorder and its treatment and underlines the complex relationship between major depressive disorder, antidepressant and sexuality.

French national health insurance database analysis and field study focusing on the impact of secure prescription pads on zolpidem consumption and sedative drug misuse: ZORRO study protocol.

INTRODUCTION: In recent years, data collected by the French Addictovigilance Network have shown the potential for abuse and addiction associated with zolpidem (the most sold hypnotic drug in France). Since 10 April 2017, new regulations have come into force that require zolpidem to be prescribed on special secure prescription pads, in order to reduce the risk of abuse or misuse. This measure has far-reaching repercussions that are not only limited to the consumption of zolpidem but also extend to the usage of sedative medication on a whole. The objective of the ZOlpidem and the Reinforcement of the Regulation of prescription Orders (ZORRO) study is to evaluate the overall impact of the new regulatory framework requiring zolpidem to be prescribed on special secure prescription pads. Three axes will be evaluated: the number of consumers, the type of consumption (chronic use versus occasional use, problematic consumption versus non-problematic use) and the consumption of other sedative molecules.The study has been registered in the Protocol Registration and Results System under the number NCT03584542 at stage "Pre-results". METHODS AND ANALYSIS: The ZORRO study is an epidemiological, observational, national multicentre, non-controlled, prospective research project supported by the French National Agency for Medicines and Health Products Safety. The evaluation of the impact of the regulatory framework change relative to zolpidem will be done according to two axes: via an epidemiological study of the French National Health Insurance database and by the implementation of field studies of prescribers and consumers of zolpidem. ETHICS AND DISSEMINATION: The Nantes Research Ethics Committee (Groupe Nantais d'Ethique dans le Domaine de la Santé), the Committee for the Protection of the Population and the Committee of Expertise in Research, Studies and Evaluations in the Field of Health approved this study. Results will be presented in national and international conferences and submitted to peer-reviewed journals. TRIAL REGISTRATION NUMBER: NCT03584542; Pre-results.

Psychiatric disorders, acne and systemic retinoids: comparison of risks.

BACKGROUND: The link between isotretinoin, treatment of a severe form of acne, and psychiatric disorders remains controversial, as acne itself could explain the occurrence of psychiatric disorders. This study aims at assessing the disproportionality of psychiatric adverse events reported with isotretinoin in the French National PharmacoVigilance Database, compared with other systemic acne treatments and systemic retinoids. MATERIALS AND METHODS: Data were extracted from the French National PharmacoVigilance Database for systemic acne treatments, systemic retinoids and drugs used as comparators. Each report was subjected to double-blind analysis by two psychiatric experts. A disproportionality analysis was performed, calculating the number of psychiatric ADRs divided by the total number of notifications for each drug of interest. RESULTS: Concerning acne systemic treatments: all 71 reports of severe psychiatric disorders involved isotretinoin, the highest proportion of mild/moderate psychiatric adverse events was reported with isotretinoin (14.1%). Among systemic retinoids, the highest proportion of severe and mild/moderate psychiatric events occurred with isotretinoin and alitretinoin. CONCLUSION: Our study raises the hypothesis that psychiatric disorders associated with isotretinoin are related to a class effect of retinoids, as a signal emerges for alitretinoin. Complementary studies are necessary to estimate the risk and further determine at-risk populations.

Benzodiazepine dependence in subjects with alcohol use disorders: what prevalence?

OBJECTIVE: To our knowledge, no studies have been conducted in France on benzodiazepine (BZD) dependence among outpatients with alcohol use disorders (AUD). Some international studies have been conducted on the consumption of BZD in this specific population, but the comparisons among them are difficult. We aimed to assess the current prevalence of probable benzodiazepine and BZD-like hypnotics (Z-drugs) dependence among outpatients seeking treatment for AUD. METHODS: Participants were patients seeking treatment for AUD for the first time or repeating treatment after more than twelve months. Recruitment took place in seven addiction centres between January and December 2013 in the Nantes region (France). BZD/Z-drug dependence was assessed according to the DSM-IV diagnostic criteria for dependence. This information was gathered through a self-report questionnaire. RESULTS: Among the 1005 patients included in this study, 413 were BZD/Z-drug users (41.1%). Among the 413 patients, 217 were probably dependent on at least one substance, which represents 21.6% of the total population and 52.5% of BZD/Z-drug users. CONCLUSION: BZD/Z-drug dependence represents a public health concern. Prescribers should take the risks into account and keep treatment courses to a minimum.

[Prescription of methylphenidate for children: importance of recommendations to limit misuse]. / Prescription de méthylphénidate chez l'enfant : importance des recommandations pour limiter la consommation problématique.

Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder appearing during childhood. Multimodal strategies have been developed to treat this disorder, some of them including medication. To this day in France, prescriptions are mainly based on methylphenidate. Ever since this drug was marketed in France in 1995, it has been subject to enhanced monitoring, mainly because of the risk of dependence, abuse, and misuse. The present study aims at assessing (1) whether the recommendations on methylphenidate use for children are being respected, (2) the extent of problematic use of methylphenidate, and (3) the impact of said recommendations being respected on the development of problematic consumption. We studied patients who were treated with methylphenidate in an academic child psychiatry department. We specifically developed a semistructured interview grid for this study. Both parents and children were interviewed. In almost three out of four cases, at least one recommendation had not been followed (52% of patients did not follow the recommendation of stopping use during weekends and holidays). We found an average of 1.6 (range, 0-5) recommendations that were not respected. In almost two out of three cases, the consumption of methylphenidate was problematic; for 40% of children, this meant the search for at least one effect other than the expected therapeutic effects, such as an intellectual, creative, or athletic boosting effect. Approximately one-third of parents also sought an effect other than therapeutic for their child. Conversely, if all of the prescription recommendations were followed, less problematic consumption was observed. Methylphenidate-based treatments must therefore be implemented after a specialist has evaluated the patient and be prescribed following the recommendations. In this context, the treatment's benefits are undeniable.

Ibuprofen dependence: a case report.

Ibuprofen is currently widely prescribed and has not been reported to produce dependence. We report the case of a 17-year old patient who presented many positive psychic symptoms related to a pharmacological dependence. During the treatment, she adjusted herself posology as she developed withdrawal symptoms. Pharmacological evidences (effect on COX-1 and COX-2, FAAH and PPARs) allow us to formulate hypotheses explaining this effect.

Aripiprazole: a new risk factor for pathological gambling? A report of 8 case reports.

OBJECTIVE: It is commonly accepted that pathological gambling results from the interaction of multiple risk factors. Among these, dopamine replacement therapy (DRT) prescribed for Parkinson disease can be cited. Another dopamine agonist, aripiprazole, could be a new risk factor. We decided to explore this potential adverse drug reaction (ADR). METHOD: Based on a cohort of 166 pathological gamblers starting treatment in our department, data of each of the 8 patients treated by aripiprazole at inclusion were analyzed. RESULTS: The patients involved were schizophrenic or bipolar, mostly young men with a history of addictive disorders and regular gambling prior to the prescription of aripiprazole. For each one of them, the causality of aripiprazole was considered, using an algorithm. The probability that pathological gambling is actually due to aripiprazole is "possible" in 7 cases out of 8, and "doubtful" in one. CONCLUSIONS: Adverse drug reactions were confronted with other already published case reports. Dopamine partial agonist mechanism of aripiprazole could explain the occurrence of pathological gambling.

How a novel programme for increasing awareness of health professionals resulted in a 14% decrease in patients using excessive doses of psychotropic drugs in western France.

INTRODUCTION: Consumption of high doses of psychotropic drugs is a public health problem in France. The Center for Evaluation and Information on Pharmacodependence and the General Health Insurance System decided that it was time to begin a regional programme on excessive consumption in a French region. PURPOSE: The objectives of this programme were: (1) get health professionals (doctors and pharmacists) to realize that some of their patients were consuming excessive doses, and (2) achieve a decrease of excessive psychotropic drug use. In addition, in the course of the programme, we were able to gather some clinical data related to heavy consumers, and evaluate their possible addiction. METHOD: This study is based on data related to 497,821 psychotropic drug consumers. Psychotropic drugs consumers whose consumption had exceeded twice the maximum allowance during at least 3 months in the second half of 2002 were contacted and unless the patients objected, a report on their personal circumstances was sent to their doctor(s) and pharmacist(s). We determined a quantitative method for the assessment of the results. RESULTS: Increasing awareness among the health professionals through this original programme resulted in a 14.1% decrease in the percentage of patients receiving excessive doses, a 66% decrease in the number of patients receiving more than twice the maximum recommended dose, among the selected cohort, and some rationalization of consumption as well as a decrease in the "doctor shopping" behaviour. CONCLUSIONS: Medical practices did evolve and health professionals became aware of the benefit of their preventive action on the decrease of drug addiction.

A simple high performance liquid chromatography assay for monitoring plasma concentrations of tipranavir in HIV infected patients.

A simple HPLC assay to determine plasma concentration of tipranavir is presented. A liquid/liquid extraction of the drugs in ethyl acetate/hexane from 250 microL of plasma is followed by a reversed phase isocratic HPLC assay with UV detection at 205 nm. The imprecision and inaccuracy are lower than 10%, the low limit of quantitation is 0.4 mg/L. Thus, this method can be used for therapeutic drug monitoring of tipranavir in HIV infected patients.
