Characterisation of medication side effects in patients with mostly resistant depression in a real-world setting

OBJECTIVES

This study aimed to identify factors associated with side effects of psychotropic drugs in a real-world setting enriched with treatment-resistant depression (TRD) patients.

METHODS

A total of 1410 depressed patients were treated in a naturalistic setting. Side effects were measured with the Udvalg for Kliniske Undersogelser Side Effect Rating Scale (UKU); the total score and UKU subscales were considered. Clinical-demographic variables were tested for association with side effects in univariate and then multivariate analyses.

RESULTS

Total, psychic and neurological side effects were associated with depressive symptom severity, while autonomic side effects were higher in those with somatic comorbidities and other side effects were lower in patients receiving trazodone. In multivariate analyses, depressive symptom severity was associated with psychic and total side effects, while generalised anxiety disorder (GAD) with neurological side effects and somatic comorbidities remained associated with autonomic side effects. Trazodone was associated with lower side effects and with augmentation treatments. Augmentation therapies showed opposite effects depending on response status, i.e. increased or decreased the risk of side effects in responders and non-responders/resistant patients, respectively.

CONCLUSIONS

Psychic side effects may be difficult to distinguish from depressive symptoms and factors associated with different types of side effects are heterogeneous and likely interacting.

Sexual functioning in females with depression in remission receiving escitalopram

BACKGROUND & OBJECTIVES

Sexual functioning is a strong determinant of quality of life. Sexual dysfunction has been widely reported due to depressive disorder as well as selective serotonin reuptake inhibitors. Thus, treatment with antidepressants can culminate in a double-edged sword, leading to drug discontinuation and symptom relapse. The objective of this study was to assess the sexual functioning of sexually active females with depression, currently in remission, receiving escitalopram and to compare with healthy controls.

METHODS

Fifty female patients with depression, currently in remission, with self-reported normal pre-morbid sexual function and receiving escitalopram for at least three months, were assessed on female sexual function index (FSFI) questionnaire and compared with healthy controls.

RESULTS

Half of the patients (n=25, 50%) in group A were found to have sexual dysfunction (FSFI score <26.55), while, 90 per cent (n=45) had decreased desire, 86 per cent (n=43) had decreased arousal, 54 per cent (n=27) had decreased lubrication, 68 per cent (n=34) had decreased orgasm, 62 per cent (n=31) had decreased satisfaction and 32 per cent (n=16) had pain during sexual activity. Patients receiving escitalopram had significantly higher sexual dysfunction as compared to healthy controls in mean total FSFI score (P < 0.001) and all mean domain scores of FSFI except pain.

INTERPRETATION & CONCLUSIONS

A significant proportion of sexually active females with depression currently in remission, receiving escitalopram, reported dysfunction in all domains of sexual function; thus, routine screening for sexual dysfunction during follow up is advisable for early identification and prompt treatment.

Função e disfunção sexual na depressão: uma revisão sistemática

RESUMO Objetivo Revisar sistematicamente as informações disponíveis acerca da função sexual e/ou disfunção sexual em pacientes com transtorno depressivo maior (TDM) e/ou distimia (DIS). Métodos Foi realizada uma busca sistematizada na base eletrônica Medline por estudos que avaliavam a função/disfunção sexual em pacientes com TDM e DIS. Foram incluídos estudos publicados até junho de 2017. Artigos relevantes presentes nas referências dos artigos foram pesquisados manualmente e incluídos nesta revisão. Resultados Vinte estudos foram elegíveis para análise. Foi observada uma grande diversidade de resultados decorrente da heterogeneidade dos delineamentos empregados e devido aos diferentes métodos de avaliação utilizados. De forma geral, os dados provenientes demonstraram uma redução das principais funções sexuais em pacientes com TDM e DIS, tais como: libido (31%-32%), drive (31%-87%), excitação (29%-85%), ereção (18%-46%), lubrificação (18%-79%) e orgasmo (26%-81%). Aumento de libido (15%-22%) também foi descrito em alguns estudos. Conclusão A disfunção sexual é altamente prevalente na DIS e no TDM. Foram notadas diversas alterações de funcionamento sexual na população estudada. Discrepâncias acerca de suas prevalências podem ter ocorrido devido às variadas metodologias de análise utilizadas nos estudos.

Amitriptyline and Sexual Function: A Systematic Review Updated for Sexual Health Practice

Amitriptyline is an old drug but is still prevalently used as the first-line treatment for a variety of common diseases. Surprisingly, knowledge of sexual risks with amitriptyline comes from only one clinical trial and several case reports from three decades ago. In the current study, a systematic review of the literature following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) related to amitriptyline and sexual dysfunction (SD) was performed. The frequency, gender-difference, types, disease-specificity and time course of SD, and the relationship between SD and nonsexual adversity were studied. A total of 14 publications, including 8 qualified randomized clinical trials, were eligible. The frequency of SD in overall, male and female patients was 5.7, 11.9 and 1.7%, respectively. SD was six-fold higher in men than women. The frequency of SD was 6.9% in depressive patients compared with 0.8% in non-depressive patients ( p = .008), and gradually decreased at 8 weeks after treatment ( p = .02). Amitriptyline impacted arousal and libido more than orgasm and ejaculation in male patients but mainly libido in female patients. SD was significantly correlated with insomnia linearly whereas somnolence and nausea dually. Therefore, amitriptyline-associated SD mainly occurs in depressive and male patients, disturbs each phase of the sexual response cycle in men but mainly libido in women, gradually decreases under long-term treatment, and can be predicted by the co-existence of insomnia, somnolence or nausea during treatment. Clinicians should caution and tailor the gender and disease vulnerability of amitriptyline in their practice.

Topiramate-associated sexual dysfunction: A systematic review

INTRODUCTION

Sexual pharmacotoxicity renders patients with epilepsy at a risk for sexual dysfunction (SD). This study is aimed to analyze the relationship between sexual function and topiramate to avoid topiramate-associated SD.

METHODS

A systematic review following the PRISMA guidelines was performed to elucidate any SD occurrence in patients receiving topiramate.

RESULTS

A total of 17 publications were reviewed. Based on limited polytherapy observational studies, the frequency of self-reported topiramate-associated SD, libido disorder, and orgasmic disorder in patients with polytherapy was 9.0%, 9.0%, and 2.6%, respectively (grade C evidence). Female patients mainly had anorgasmia, whereas male patients principally had erectile dysfunction. The daily dose of topiramate in patients with SD was within the recommended dose. Sexual adversity usually occurred from 4weeks after topiramate use but favorably subsided without eventful complications after topiramate substitution or dose reduction in all patients.

CONCLUSIONS

Topiramate can elicit different patterns of SD, especially anorgasmia in women and erectile dysfunction in men, even with a therapeutic dose. Detailed drug education and careful monitoring are necessary to maximize sexual health, especially in persons undergoing polytherapy and with other risks for SD. Moreover, a rapid response, such as substitution or reduction of the dose, is suggested when SD occurs during its use.

Psychiatric disorders and sexual dysfunction

Sexual problems are highly prevalent among patients with psychiatric disorders. They may be caused by the psychopathology of the psychiatric disorder but also by its pharmacotherapy. Both positive symptoms (e.g., psychosis, hallucinations) as well as negative symptoms (e.g., anhedonia) of schizophrenia may negatively interfere with interpersonal and sexual relationships. Atypical antipsychotics have fewer sexual side-effects than the classic antipsychotics. Mood disorders may affect libido, sexual arousal, orgasm, and erectile function. With the exception of bupropion, agomelatine, mirtazapine, vortioxetine, amineptine, and moclobemide, all antidepressants cause sexual side-effects. Selective serotonin reuptake inhibitors (SSRIs) may particularly delay ejaculation and female orgasm, but also can cause decreased libido and erectile difficulties. SSRI-induced sexual side-effects are dose-dependent and reversible. Very rarely, their sexual side-effects persist after SSRI discontinuation. This is often preceded by genital anesthesia. Some personality characteristics are a risk factor for sexual dysfunction. Also patients with eating disorders may suffer from sexual difficulties. So far, research into psychotropic-induced sexual side-effects suffers from substantial methodologic limitations. Patients tend not to talk with their clinician about their sexual life. Psychiatrists and other doctors need to take the initiative to talk about the patient's sexual life in order to become informed about potential medication-induced sexual difficulties.
