Serum prolactin levels and sexual dysfunction in patients with schizophrenia treated with antipsychotics: comparison between aripiprazole and other atypical antipsychotics

Cerebral Computed Tomographic Findings in Schizophrenia: Relationship to Second-Generation Antipsychotics and Hyperprolactinemia

Antipsychotic medications are essential for managing severe mental illnesses like schizophrenia, which impacts about 1% of the global population. Despite efficacy, in some cases, they can induce hyperprolactinemia, affecting roughly half of the patients. The prevalence of this condition varies with the specific medication used. Although prolactinomas are rare among schizophrenia patients, treating them with dopamine agonists poses conflicts with antipsychotic medication, necessitating careful monitoring and adjustments. The aim of this study was to explore the presence of brain tumors, prolactinomas, and other structural brain changes in schizophrenia patients treated with second-generation antipsychotics using cerebral computed tomography (CT) scans. We conducted a cross-sectional study involving 152 hospitalized patients diagnosed between 1 January 2020 and 31 March 2024. Evaluations included cerebral CT scans, prolactin level assessments, and the monitoring of side effects. Patients, with an average age of 42.79 years and an illness duration of 17.89 years, predominantly received olanzapine (46.05%) and risperidone (36.84%). Side effects, reported by 61.78% of patients, included tremors, dizziness, and weight gain. Abnormal prolactin levels were observed in 53.95% of patients, more prevalent in females on risperidone and in both genders on olanzapine. No prolactinomas were detected on CT scans. Managing hyperprolactinemia in schizophrenia patients undergoing antipsychotic therapy is essential to prevent long-term complications and to ensure treatment compliance.

The Relationship Between Sexual Dysfunctions With Disease Prolactin and Genetic Polymorphisms in Schizophrenia and Bipolar Disorder Patients Receiving Pharmacotherapy

OBJECTIVE

The aim of this study is to investigate sexual dysfunctions (SDs) and related factors in patients with schizophrenia and bipolar disorder receiving pharmacotherapy.

METHODS

This study included 111 patients. The Scale for the Assessment of Positive Symptoms (SAPS), the Scale for the Assessment of Negative Symptoms (SANS), and the Calgary Depression Scale for Schizophrenia (CDSS) were applied to the schizophrenia, and the Young Mania Rating Scale (YMRS) and Hamilton Depression Rating Scale (HAM-D) to the bipolar patient group. The sociodemographic data form and the Arizona Sexual Experiences Scale (ASEX) were applied to both of the patient groups. Blood was drawn from all patients to evaluate the indicated gene polymorphisms and evaluate prolactin levels.

RESULTS

SD was detected in 45.9% (N = 34) of the schizophrenia group, and 59.5% (N = 22) in the bipolar disorder group. SD was significantly higher in elderly patients and patients with a high smoking amount and low education levels. The eNOS -786T>C T allele frequency was found to be significantly higher in patients with SD. The logistic regression analysis determined that eNOS -786T>C CT and TT genotypes increased the risk of SD.

CONCLUSION

In this study, the high rates of SD in patients with schizophrenia and bipolar disorder, and the presence of modifiable factors that influence the presence of SD, suggest that SD should be given more attention in these patient groups. On the other hand, the high rate of SD in patients with the eNOS -786T>C T allele indicates the importance of carrying out new studies investigating the factors affecting the enzyme activity in this genotype. There is a need for more studies on eNOS genotypes and enzyme activites in this area.

Sexual Dysfunction in Schizophrenia: A Systematic Review and Meta-Analysis

Importance

In individuals with schizophrenia, antipsychotic-induced dysfunctions are frequent but often underexplored in clinical practice.

Objective

To synthetize the data of observational studies exploring the prevalence of sexual dysfunction in individuals with schizophrenia-spectrum disorders as well as associated factors.

Data Sources

A systematic literature search without language or time restrictions was conducted in Google, Google Scholar, PubMed/MEDLINE, Science Direct, and Université Sorbonne Paris Cité for studies published up to June 8, 2022.

Study Selection

All observational studies reporting a prevalence of sexual dysfunction in schizophrenia-spectrum disorder were included.

Data Extraction and Synthesis

The MOOSE guidelines with independent extraction by 2 observers and random-effects models were used.

Main Outcomes and Measures

The prevalence of sexual dysfunction and each specific dysfunction.

Results

A total of 72 of 1119 studies from 33 countries on 6 continents published from inception to June 2022 were included with a total of 21 076 participants with schizophrenia. The pooled global prevalence of sexual dysfunctions was 56.4% (95% CI, 50.5-62.2), with a prevalence of 55.7% (95% CI, 48.1-63.1) for men and 60.0% (95% CI, 48.0-70.8) for women. The most frequent sexual dysfunction was erectile dysfunction in men (44%; 95% CI, 33.5-55.2), followed by loss of libido in men (41%; 95% CI, 30.7-51.4), ejaculation dysfunction in men (39%; 95% CI, 26.8-51.8), orgasm dysfunction in women (28%; 95% CI, 18.4-40.2), and amenorrhea in women (25%; 95% CI, 17.3-35.0). Factors associated with heterogeneity were study design, time and location, sociodemographic data, alcohol use disorder, psychiatric diagnosis, illness severity, and the use of antidepressants and anxiolytics. Sexual dysfunctions were more frequent in schizophrenia vs schizoaffective disorders, and erectile disorders were less frequent in individuals with longer illness duration. Antidepressant and mood stabilizer prescriptions were associated with lower rates of erection disorders (β, -6.30; 95% CI, -10.82 to -1.78); P = .006 and -13.21; 95% CI, -17.59 to -8.83; P < .001, respectively) and ejaculation disorders (β, -6.10; 95% CI, -10.68 to -1.53; P = .009 and β, -11.57; 95% CI, -16.34 to -6.80; P < .001, respectively). No obvious improvements in the rates of sexual dysfunction at other times were found, and there were conflicting results regarding antipsychotic classes.

Conclusions and Relevance

This systematic review and meta-analysis found a high prevalence of sexual dysfunction among individuals with schizophrenia, with considerable heterogeneity in associated factors. The findings also suggest that some dysfunctions may be explained by schizophrenia. The association between lower rates of dysfunction and antidepressant use suggests that treating comorbid depression could be an effective strategy to improve sexual health. A lack of data on metabolic parameters and physical health in general was also noted, while these issues are frequent in the care of schizophrenia.

Dopamine partial agonists: a discrete class of antipsychotics

Worldwide, there are now three marketed dopamine D2 partial agonists: aripiprazole, brexpiprazole and cariprazine. These three drugs share a number of properties other than their action at D2 receptors. Pharmacologically, they are 5HT2 antagonists and D3 and 5HT1A partial agonists but with little or no alpha-adrenergic, anticholinergic or antihistaminic activity. They also share a long duration of action. Clinically, D2 partial agonists are effective antipsychotics and generally have useful antimanic and antidepressant activity. They are usually well tolerated, causing akathisia and insomnia only at the start of treatment, and are non-sedating. These drugs also share a very low risk of increased prolactin and of weight gain and accompanying metabolic effects. They may also have a relatively low risk of tardive dyskinesia. There is some evidence that they are preferred by patients to dopamine antagonists. Individual dopamineD2 partial agonists have much in common and as a group they differ importantly from dopamine D2 antagonists. Dopamine D2 partial agonists should be considered a distinct class of antipsychotics.Key pointsD2 partial agonists share many pharmacological and clinical propertiesD2 partial agonists differ in several important respects from D2 antagonistsD2 partial agonists should be considered a discrete class of antipsychotics.

Long-Term Proton Pump Inhibitor Therapy and its Effect on Endocrine Hormones in Selected Patient Population

Proton pump inhibitors (PPI) are commonly prescribed medications for a variety of gastrointestinal disorders around the globe. Long-term utilization of proton pump inhibitors is linked with different adverse events. Although, short-term therapy has been demonstrated to have little or no impact on endocrine hormones in men, yet its safety with long-term use has poorly been studied. We aimed to evaluate the impacts of long-term utilization of proton pump inhibitors on male reproductive hormones and its clinical outcomes. A cross-sectional study was performed in two out-patients gastroenterology clinics in Khyber Pakhtunkhwa province. Male patients who were using PPIs regularly for≥3 months were enrolled in this study. Among 65 enrolled participants, patients with sexual complaints have significant variations in mean serum levels of prolactin (p<0.001), sex hormone binding globulins (p=0.043), total testosterone (p<0.001) and progesterone (p=0.001) as compared to patients without sexual complaints. Significantly high values of prolactin mean ranks were observed in patient with sexual complaints (p<0.001). There were statistically significant correlations of serum levels of sex hormone binding globulins (p=0.003), total testosterone (p=0.008) and progesterone (p<0.001) with serum prolactin levels. Similarly, statistically significant variation was observed for decreased libido (p=0.001), erectile dysfunction (p=0.001) and decreased semen mass ((p<0.001) between normal and hyperprolactinemic PPI users. Highly significant differences were observed in serum sex hormone binding globulins (p<0.001), total testosterone (p<0.001) and progesterone (p<0.001) values in normal and hyperprolactinemic groups. In conclusion, long-term utilization of PPI may induce endocrine hormone disruption with subsequent sexual complications.

Comparison of prolactin level, sexual function, body mass index, and liver function tests in patients using depot antipsychotics

Amaç: Bu çalışmada uzun etkili antipsikotik ilaç formları (uzun etkili paliperidon palmitat, risperidon depo ve zuklopentiksol depo) kullanan hastalarda cinsel işlev bozuklukları, vücut kitle indeksi, karaciğer fonksiyon testleri ve prolaktin düzeylerinin karşılaştırılması amaçlanmıştır. Gereç ve Yöntem: Bu çalışmaya şizofreni tanılı ve uzun etkili antipsikotik tedavisi alan hastalar dahil edildi. Tüm katılımcılara demografik veri formu, Pozitif ve Negatif Sendrom Ölçeği (PANSS), Calgary Şizofrenide Depresyon Ölçeği (CŞDÖ) ve Arizona Cinsel Yaşantılar Ölçeği (ACYÖ) uygulandı. Ardından üre, kreatinin, karaciğer fonksiyon testleri, kolesterol ve prolaktin düzeylerini değerlendirmek için venöz kan örnekleri alındı. Bulgular: Çalışmaya 95 hasta dahil edildi. Dahil edilenlerin 79’u erkek (%83.2) ve 16’sı kadındı (%16.8). Tüm hastaların yaş ortalaması 36.77±10.24 yıl idi. Vücut kitle indeksleri ortalaması ise 27.06±4.95 kg/m2 idi. Gruplar arasında ACYÖ ve CŞDÖ skorları açısından farklılık saptanmadı. Prolaktin değeri paliperidon depo kullanan hastalarda zuklopentiksol depo kullanan hastalardan yüksek olarak hesap edilmiştir. Sonuç: Sonuçlarımıza göre cinsel işlevleri etkileyen prolaktin değerleri, hastalar semptom belirtmese de uzun etkili antipsikotik kullanan hastalarda göz önünde bulundurulmalıdır. Uzun etkili antipsikotik kullanımının hem prolaktin değerleri hem de diğer laboratuvar parametrelerine olan etkileri konusunda ileri araştırmalar yapılmalıdır.

Sexual dysfunction in people treated with long-acting injectable antipsychotics in monotherapy or polypharmacy: a naturalistic study

Sexual dysfunction, psychosis, and antipsychotics are known to be related, but the precise association between them is still unknown. Most evidence about the prevalence of sexual dysfunction in people treated with antipsychotic drugs comes from studies with restrictive samples. That is why our main objective was to determine the prevalence of sexual dysfunction in a real-life sample of outpatients treated with antipsychotics, considering gender. A cross-sectional naturalistic study was developed, including people treated with long-acting injectable antipsychotics, with or without other psychotropic drugs. Participants were interviewed to assess sexual satisfaction through a Likert scale (0 to 10) and the presence of sexual dysfunction (the Psychotropic-Related Sexual Dysfunction Questionnaire, PRSexDQ-SALSEX). The participants also had a blood test to determine prolactin (men and women) and testosterone levels (men only). A total of 131 people participated in the study (90 men and 41 women). Some extent of sexual dysfunction was found in 62.2% of men and 51.2% of women. The most frequent sexual dysfunction symptom for both genders was the loss of libido (45%). Hyperprolactinemia was present in 56% of men and 61% of women. The presence of sexual dysfunction was associated with higher doses of antipsychotics, hyperprolactinemia, and smoking in men and with smoking and hyperprolactinemia in postmenopausal women. This study provides real-life evidence of sexual dysfunction and hyperprolactinemia in persons treated with long-acting injectable antipsychotics segregated by gender. The high rates of sexual dysfunction and hyperprolactinemia detected corroborate the need to consider these aspects in clinical practice.

Sexual Dysfunction in Schizophrenia: A Narrative Review of the Mechanisms and Clinical Considerations

Psychiatric disorders, in general, have a high prevalence of sexual problems, whether from the psychopathology of the disorder itself, pre-existing or co-morbid sexual disorder or from side effects of the treatment for mental disorders. Many patients report an already existing sexual dysfunction at the onset of diagnosis. The risk association for developing sexual dysfunction in patients with schizophrenia includes antipsychotic use and resulting hyperprolactinemia, age, gender, and disease severity. Medication side effects lead to nonadherence, and relapses lead to structural changes in the brain, treatment resistance, and worsening of symptoms. Findings in certain studies propose serum prolactin and thyroid-stimulating hormone measurement as a tool for assessing patients with schizophrenia for sexual dysfunction. Regarding specific symptoms, females especially reported decreased desire at baseline and galactorrhea after treatment. The findings of this review, therefore, suggest that sexual dysfunction may be present in patients with schizophrenia before starting antipsychotic treatment and that patients, especially those who are female, are likely to develop hyperprolactinemia with antipsychotic treatment. Aripiprazole may be an emergent treatment for sexual dysfunction in those who use antipsychotics. It is important for patients to consider sexual dysfunction prior to prescribing antipsychotics. Since sexual dysfunction can impact a patient’s quality of life and affect treatment adherence, it is important for physicians to be aware and monitor patients for symptoms.

Is Adjunct Aripiprazole Effective in Treating Hyperprolactinemia Induced by Psychotropic Medication? A Narrative Review

Psychotropic medication treatment can cause elevated serum prolactin levels and hyperprolactinaemia (HPRL). Reports have suggested that aripiprazole may decrease elevated prolactin. The aim of this review was to assess evidence for the efficacy of adjunct aripiprazole in the treatment of psychotropic-induced HPRL. PubMed and Google Scholar were searched to identify randomised placebo-controlled trials (RCTs) of adjunct aripiprazole in patients with HPRL attributed to primary psychotropic medications. Data for individual patients from case studies, chart reviews and open-label studies were also identified and assessed. Six RCTs, with a total of 609 patients, met inclusion criteria. Primary psychotropics included risperidone, haloperidol, paliperidone, fluphenazine and loxapine. Reductions in prolactin from baseline, before the introduction of aripiprazole, were significantly greater for adjunct aripiprazole than for adjunct placebo in all the studies (p = 0.04 to p < 0.0001). Normalisation of serum prolactin levels was significantly more likely with adjunct aripiprazole than adjunct placebo (p = 0.028 to p < 0.001, data from three studies). Improvement or resolution of HPRL-related symptoms (galactorrhoea, oligomenorrhoea, amenorrhoea and sexual dysfunction) were reported in three studies. Prolactin levels decreased in all case reports and in both of two open-label studies; they normalised in 30/41 patients (73.2%) in case studies and 12/29 (41.4%) in the open-label studies. Adjunct aripiprazole was statistically significantly effective in treating elevated serum prolactin levels in six RCTs. Evidence from case reports and open-label studies suggests a degree of effectiveness in most patients.

Management Strategies for Antipsychotic-Related Sexual Dysfunction: A Clinical Approach

Antipsychotic medication can be often associated with sexual dysfunction (SD). Given its intimate nature, treatment emergent sexual dysfunction (TESD) remains underestimated in clinical practice. However, psychotic patients consider sexual issues as important as first rank psychotic symptoms, and their disenchantment with TESD can lead to important patient distress and treatment drop-out. In this paper, we detail some management strategies for TESD from a clinical perspective, ranging from prevention (carefully choosing an antipsychotic with a low rate of TESD) to possible pharmacological interventions aimed at improving patients' tolerability when TESD is present. The suggested recommendations include the following: prescribing either aripiprazole or another dopaminergic agonist as a first option antipsychotic or switching to it whenever possible. Whenever this is not possible, adjunctive treatment with aripiprazole seems to also be beneficial for reducing TESD. Some antipsychotics, like olanzapine, quetiapine, or ziprasidone, have less impact on sexual function than others, so they are an optimal second choice. Finally, a variety of useful strategies (such as the addition of sildenafil) are also described where the previous ones cannot be applied, although they may not yield as optimal results.

Influence of the use of atypical antipsychotics in metabolic syndrome

OBJECTIVES

To describe the possible relationship between the use of antipsychotic drugs and the presence of metabolic syndrome. Other objectives are to list the main side effects of antipsychotic treatment, and to determine if there is any pharmacological treatment that can contribute towards counteracting metabolic syndrome.

MATERIAL AND METHOD

A narrative bibliographic review was carried out of the following databases: PubMed, Cochrane, CINAHL, IBECS, LILACS and HealthCare. Preference in the selection process was given to clinical trials and systematic review articles or review articles and some articles that were considered relevant because of their content. The time period was limited to between January 2014 and November 2019. The languages were English and Spanish. Repeated articles and those that were not related to the objectives were rejected. The search criteria were: "antipsychotic AND metabolic syndrome"; "schizophrenia AND metabolic syndrome"; "bipolar disorder AND metabolic syndrome"; "metabolic syndrome AND suicide NOT disorder"; "metabolic syndrome AND prisons"; "metabolic syndrome AND prolactin".

RESULTS

24 articles were selected out of the 510 that were consulted. The relationship between atypical antipsychotics and metabolic syndrome was evident. Other anticholinergic, antidopaminergic effects, extrapyramidal syndromes, neuroleptic malignant syndrome, hypotension, arrhythmias, sedation, hypovitaminosis D, increased prolactin, sexual dysfunction, sleep disturbances, etc. are also highlighted. Pharmacological associations with other drugs were also found.

DISCUSSION

There is a relationship between the use of atypical antipsychotics and weight gain, lipid disorders, glucose and high blood pressure. There are some associated drugs that decrease some symptoms (ranitidine, topiramate, metformin, melatonin, modafinil). Patients taking this type of medication should be monitored and encouraged to lead healthy lifestyles.

Is There an Association Between Schizophrenia and Sexual Dysfunction in Both Sexes? A Systematic Review and Meta-Analysis

BACKGROUND

Mounting clinical studies have reported patients with schizophrenia are at high risk of developing sexual dysfunction (SD), but a directly calculated prevalence of SD is currently lacking.

AIM

To further quantify the association between schizophrenia and SD.

METHODS

MEDLINE (PubMed), Embase (OVID), the Cochrane Library databases, and the PsycINFO were systematically searched for eligible studies reporting the sexual functioning in patients with schizophrenia. This meta-analysis has been registered on PROSPERO (ID: CRD42019121720, http://www.crd.york.ac.uk/PROSPERO).

OUTCOMES

The relationship between schizophrenia and SD was detected by calculating the relative risk (RR) with a 95% confidence interval (CI). The GRADE-profiler was employed to rank the quality of the evidence.

RESULTS

10 observational studies (3 case-control studies and 7 cross-sectional studies) were finally included, enrolling a total of 3,570 participants (mean age 28.6-46.2 years), of whom 1,161 had schizophrenia and the remainders were the healthy control subjects. Synthetic results indicated that schizophrenia was significantly associated with an increased risk of SD regardless of gender (3 studies reporting both sexes: RR = 2.24, 95%CI: 1.66-3.03, P < .001, heterogeneity: I² = 0.0%, P = .431; 7 studies reporting men: RR = 2.63, 95%CI: 1.68-4.13, P < .001, heterogeneity: I² = 82.7%, P < .001; 5 studies reporting women: RR = 2.07, 95%CI: 1.46-2.94, P < .001; heterogeneity: I² = 79.7%, P = .001). In accordance with the GRADE-profiler, the quality of the evidence of primary outcomes was LOW, MODERATE, and LOW in studies including both sexes, men, and women, respectively.

CLINICAL IMPLICATIONS

Our findings confirmed the potential link between schizophrenia and SD. Clinicians should routinely assess the sexual functioning for those patients with schizophrenia and further recommend the preferred antipsychotics for them.

STRENGTHS & LIMITATIONS

This is the first meta-analysis investigating the association between schizophrenia and the risks of SD in both sexes. Nonetheless, substantial heterogeneities were identified across the selected studies.

CONCLUSION

Robust data from this meta-analysis showed increased rates of SD in patients with schizophrenia compared with the general populations. Therefore, more specific psychological and pharmaceutical interventions are needed to help patients with schizophrenia gain a better sexual life. Zhao S, Wang X, Qiang X, et al.

Blonanserin vs risperidone in Japanese patients with schizophrenia: A post hoc analysis of a phase 3, 8-week, multicenter, double-blind, randomized controlled study

OBJECTIVE

To report the efficacy and safety of blonanserin in patients with schizophrenia compared with risperidone in a Japanese multicenter, randomized, double-blind study based on post hoc sensitivity analysis in addition to the previous results reported by Miura and discuss the current approaches for schizophrenia treatment.

METHODS

Of 302 patients randomized, 156 received blonanserin (8-24 mg/d) and 145 received risperidone (2-6 mg/d) for 8 weeks. Efficacy variables included the Positive and Negative Syndrome Scale (PANSS) total score for the primary outcome, PANSS subscale, Brief Psychiatric Rating Scale (BPRS), and Clinical Global Impression-Improvement (CGI-I) for secondary outcomes. Safety variables included treatment-emergent adverse events, Drug Induced Extrapyramidal Symptoms Scale scores, laboratory data, vital signs, electrocardiogram, etc RESULTS: Blonanserin was not inferior to risperidone in the change in PANSS total score at a non-inferior margin of -7 (intergroup difference, -0.46; 95% CI, -4.40 to 3.48). Post hoc analyses wholly supported the primary result. No major difference was found in the changes in BPRS scores and the improvement rate on CGI-I between the drugs. The incidence of adverse events was similar in the two drugs. Blonanserin was associated with a lower risk of prolactin increase, weight gain, and orthostatic hypotension compared with risperidone. However, blonanserin was associated with a higher incidence of akathisia and excitability compared with risperidone. Most of the adverse events were mild to moderate in severity with no specific events of predominant high severity in the both drugs.

CONCLUSIONS

Blonanserin exerted the similar efficacy to risperidone in both positive and negative symptoms in schizophrenia with a lower risk of prolactin increase, weight gain, and orthostatic hypotension compared with risperidone. Blonanserin will serve as a favorable treatment option for schizophrenia in daily clinical practice.

Management of Antipsychotic-Related Sexual Dysfunction: Systematic Review

INTRODUCTION

Sexual dysfunction is one of the most frequently occurring side-effects of antipsychotic medication, impacting both quality of life and adherence to treatment. Despite this, limited evidence-based guidance on treatment options is available.

AIM

To synthesize and analyze the evidence on management of antipsychotic-related sexual dysfunction, specifically taking note of the more recently developed antipsychotics that have been incorporated in studies over the past decade.

METHODS

EMBASE, Medline, and PsychINFO databases were searched using search terms related to sexual or erectile dysfunction, treatments, and antipsychotics. 2 reviewers independently assessed papers for the inclusion criteria for randomized controlled trials (RCTs) of treatments for antipsychotic-related sexual dysfunction, including adjunctive medications and a switch of antipsychotic. Studies were excluded if participants did not have recorded sexual dysfunction at baseline.

MAIN OUTCOME MEASURE

The primary outcome measure was any change in sexual function.

RESULTS

6 RCTs were identified, all of which investigated different interventions; hence, it was not possible to synthesize the data quantitatively. Results were overall limited by small sample size, brief treatment duration, and the potential for bias. 2 studies, one assessing adjunctive sildenafil and the other adjunctive aripiprazole, reported a reduction in antipsychotic-related sexual dysfunction.

CLINICAL IMPLICATIONS

Due to the lack of high-quality data, no clinical recommendations can be made.

STRENGTHS & LIMITATIONS

A comprehensive search strategy was used with an extensive number of relevant search terms including "erectile dysfunction" and newer antipsychotics such as aripiprazole. In light of evidence that prolactin is not a reliable marker for sexual dysfunction, this review focused its inclusion criteria on participants presenting with sexual dysfunction rather than with hyperprolactinemia, which should give its recommendations more validity. However, only 6 RCTs were identified, and results were overall limited by small sample size, brief treatment duration, and the potential for bias.

CONCLUSION

Our findings highlight the paucity of high-quality research in this area, and conjecture that it may be difficult to recruit participants with antipsychotic-related sexual dysfunction. Future research may be necessary to unlock and address these difficulties. Furthermore, fully powered future studies should focus on the management of sexual dysfunction rather than the surrogate marker of hyperprolactinemia. Allen K, Baban A, Munjiza J, et al.

Physiological Measurements for Prescribing Psychotropic Medications

Prescribing for individuals with mental health problems requires a thorough initial assessment that includes extensive interviewing of the client and significant others, review of medical records, and physical appraisals, such as vital signs, laboratory tests, and electrocardiography. Arriving at a diagnosis and treatment plan includes ruling out comorbid conditions as well as medical conditions that mimic psychiatric disorders. Because substance use frequently coincides with other psychiatric disorders and has serious health consequences, this potential for misuse of substances must also be considered. The current article focuses on the physiological assessments necessary for prescribing and monitoring psychotropic medications.

Safety and Tolerability of Antipsychotic Medication in Individuals with Autism Spectrum Disorder: A Systematic Review and Meta-Analysis

BACKGROUND

Antipsychotic medication is a commonly prescribed drug class in individuals with autism spectrum disorder (ASD). However, the safety of these agents has not been fully assessed.

OBJECTIVE

Our objective was to investigate the safety and tolerability profile of antipsychotics in individuals with ASD.

METHODS

The Cochrane Library, MEDLINE, Embase and PsycINFO databases were searched up to January 2018. We included studies that reported adverse events (AEs) in participants with ASD taking first- or second-generation antipsychotic medication. The studies included in the analysis were randomized controlled trials (RCTs) and observational studies that were comparative or noncomparative and published as full text in the English language. The primary outcome of this review was AEs of any severity reported with antipsychotic use at any dose. Meta-analysis was performed on studies with child and adolescent participants to estimate the pooled prevalence of the overall AEs and the relative risk (RR) of AEs associated with antipsychotic use using a random-effects model. The Cochrane Collaboration tool and the modified Newcastle-Ottawa Scale (NOS) were used to assess the risk of bias of the included RCTs and observational studies, respectively.

RESULTS

In total, 54 citations fulfilled the inclusion criteria, of which 40 were RCTs and 14 were observational studies; eight RCTs were included in the meta-analysis to estimate the RR of AEs associated with antipsychotic use and seven observational studies were included to estimate the pooled prevalence of AEs. The RR of AEs with antipsychotic treatment was 22% higher than with placebo (RR 1.22; 95% confidence interval [CI] 1.11-1.34; I² = 30.6%; p = 0.184). The estimated pooled prevalence of AEs was 50.5% (95% CI 33-67). The most commonly reported AEs were increased appetite and weight gain, which were associated with discontinuation in many participants.

CONCLUSION

Antipsychotic-related AEs were common among patients with ASD. Further studies to investigate the implications of antipsychotic-related AEs on health and medication adherence are warranted. PROSPERO registration number: (CRD42018083632).

Neurobiology of male sexual dysfunctions in psychiatric disorders: the cases of depression, anxiety, mania and schizophrenia

While the pathophysiology of several psychiatric disorders has become modestly elucidated in the last decade, comorbid sexual dysfunctions in such patients are frequently left apart from clinical and research interest. We aimed to address the malfunctioning neurocircuitry underlying sexual dysfunctions in depression, anxiety, schizophrenia and mania. We performed a comprehensive literature review, addressing any combination of the topics of "neurobiology"/"neural", "sexual"/"desire"/"arousal"/"orgasm"/"ejaculation" and "depression"/"anxiety"/"schizophrenia"/"mania"/"bipolar". Altered neurotransmitter levels or connectivity in patients are reported in sexual dysfunctions (either desire, arousal, orgasm and ejaculation) and main psychiatric disorders (depression, anxiety, mania and schizophrenia). Neuronal pathways responsible for the occurrence of sexual dysfunctions in psychiatric disorders can be  figured out by overlap  of their acknowledged pathophysiology. However, specific research in that group is scant, so future tailored studies are warranted to elucidate actual mechanisms.

Head-to-head comparison of 1-year aripiprazole long-acting injectable (LAI) versus paliperidone LAI in comorbid psychosis and substance use disorder: impact on clinical status, substance craving, and quality of life

BACKGROUND

To overcome nonadherence in patients with psychosis switch to long-acting injectable (LAI) antipsychotic formulations is adopted. Most oral versus LAI comparisons showed similar antipsychotic responses. Psychoses often overlap with substance use disorder (SUD). Head-to-head LAI comparisons have hitherto focused only on non-comorbid populations.

OBJECTIVE

The objective of this study was to compare two LAIs, administered for 12 months, in initially hospitalized patients with psychosis comorbid with SUD in their clinical and quality of life (QoL) outcomes.

PATIENTS AND METHODS

Inpatients were recruited during 2016 and switched randomly to 400 mg intramuscular aripiprazole monohydrate (AM) (N=50) or to 100 mg intramuscular paliperidone palmitate (PP) once-monthly (N=51); patients were discharged and followed up for 12 months. Patients were rated at baseline and after 1 year through the Clinical Global Impression scale - severity (CGIs), substance craving intensity was rated through a visual analog scale for substance craving, and QoL through the World Health Organization (WHOQOL-BREF) scale. We addressed confounders with backward stepwise logistic regression and three-way analysis of variance.

RESULTS

PP were older and had more cases of schizophrenia spectrum and less bipolar disorders than AM, but AM had a stronger craving for substances at baseline. Both LAIs were associated with significant improvements in all outcomes, with AM displaying stronger effect sizes than PP. The two groups did not differ on baseline WHOQOL-BREF scores in any domain, but at the 1-year follow-up, AM fared better on all domains. The two groups did not differ in final severity, but PP scored higher than AM in craving at the 1-year endpoint.Limitation: The CGIs is not a refined tool for severity and the substance craving may be subject to recall bias.

CONCLUSION

1-year AM and PP was followed by improved clinical status and QoL and reduced substance craving in a population with psychosis and SUD comorbidity. AM, compared to PP, improved craving and QoL at the 1-year follow-up.
