Efficacy and safety of 5-hydroxytryptamine-3 (5-HT3) receptor antagonists in augmentation with selective serotonin reuptake inhibitors (SSRIs) in the treatment of moderate to severe obsessive-compulsive disorder: a systematic review and meta-analysis of randomized clinical trials.

Obsessive-compulsive disorder (OCD) is the fourth most common mental disorder, and selective serotonin reuptake inhibitors (SSRIs) are the cornerstone of its pharmacological treatment. About 40-60% of the cases are treatment-refractory, and this makes searching for second-line treatment necessary. 5-Hydroxytryptamine-3 (5-HT3) antagonists are among the many medications that have been used in augmentation with SSRIs. In this systematic review and meta-analysis, we assessed the efficacy and safety of 5-HT3 receptor antagonists in augmentation with SSRIs in treating moderate to severe OCD. We searched PubMed, Web of Science, Scopus, Cochrane library, and Google Scholar for relevant trials published up to December 2022. The effect size was the mean difference in Yale-Brown obsessive compulsive scale (Y-BOCS) scores before and after receiving 5-HT3 receptor antagonist drugs in augmentation with SSRIs in moderate to severe OCD patients. We included 6 randomized-controlled trails (RCTs) with 334 patients assessing the effect of the augmentation of SSRIs with ondansetron, granisetron, and tropisetron on treating moderate to severe OCD. Our results were in favor of the experimental group in total (Z = 8.37, P < 0.00001), in the compulsion subgroup (Z = 5.22, P < 0.00001), and in the obsession subgroup (Z = 8.33, P < 0.00001). They are well-tolerated, and have mild side effects and do not result in withdrawal. Augmentation of 5-HT3 antagonists with SSRIs can be beneficial in treating moderate to severe OCD. Further multi-center trials under adequate conditions in longer periods are needed to help come up with a comprehensive action plan.

Reboxetine Combination Therapy With Fluoxetine in Moderate to Severe Obsessive-Compulsive Disorder: A Placebo-Controlled, Double-Blind, Randomized Trial.

OBJECTIVES: Reboxetine is a potent and selective norepinephrine reuptake inhibitor that was effective in combination with citalopram for resistant obsessive-compulsive disorder (OCD). This study aims to assess its effectiveness and tolerability in combination with fluoxetine in treating OCD. METHODS: In this 2-center, placebo-controlled, and double-blind, randomized clinical trial, 76 patients with OCD were assigned into 2 parallel groups to receive fluoxetine (up to 80 mg/d) plus placebo (F + P) or fluoxetine (up to 80 mg/d) plus reboxetine (F + R) (10 mg twice daily) for 10 weeks. Participants were assessed with the Yale-Brown Obsessive Compulsive Scale (Y-BOCS) at baseline and weeks 5 and 10. RESULTS: A total of 76 patients completed the trial. There was no significant difference between the 2 groups in baseline Y-BOCS scores. General linear model repeated-measures showed significant effects on time × treatment interaction on total Y-BOCS ( F = 6.33, df = 1.42, P = 0.006) and obsession subscale scores ( F = 10.39, df = 1.48, P < 0.001), and insignificance on compulsion subscale scores ( F = 1.86, df = 1.24, P = 0.173). Reboxetine combination therapy demonstrated a higher partial and complete treatment response rate ( P < 0.01) according to the Y-BOCS total scores. There was no significant difference between the 2 groups in the frequency of adverse effects. CONCLUSIONS: Reboxetine combination therapy with fluoxetine can effectively improve symptoms in patients with OCD in a short period of treatment. However, further studies with larger sample sizes and longer follow-up periods are needed to confirm these findings.This trial was registered with the Iranian Registry of Clinical Trials ( www.irct.ir ; No IRCT20090117001556N129).

L-theanine combination therapy with fluvoxamine in moderate-to-severe obsessive-compulsive disorder: A placebo-controlled, double-blind, randomized trial.

AIM: The main aim of this study was to investigate the additional effects of L-theanine, an amino acid in tea and an analog of glutamate with neuroprotective and anti-depressant properties, on obsessive-compulsive disorder (OCD) symptoms in combination with fluvoxamine. METHODS: Patients from either sex aged between 18 and 60 years diagnosed with OCD, based on the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), who had a Yale-Brown Obsessive Compulsive Scale (Y-BOCS) score of more than 21 were enrolled in a double-blinded, parallel-group, placebo-controlled, clinical trial of 10 weeks to receive either L-theanine (100 mg twice daily) and fluvoxamine (100 mg daily initially followed by 200 mg daily after week 5) or placebo and fluvoxamine. The primary outcome of interest in this study was the Y-BOCS total score decrease from baseline. RESULTS: From a total of 95 evaluated patients, 50 completed our study; 30 were randomly assigned to each group. Multivariate analysis (ANOVA) showed a significant effect of time × $$ \times $$ treatment for L-theanine in obsession subscale (F = 5.51, P = 0.008) of the Y-BOCS score but not in the total and compulsion scores. Our results showed significantly more improvement in obsession subscale scores in L-theanine compared to placebo group (P = 0.007, Cohen's d = 0.82). Also, total Y-BOCS scores were lower in L-theanine compared to placebo group at week 5 (P = 0.039, Cohen's d = 0.60) and 10 (P = 0.008, Cohen's d = 0.80). However, there was no significant between-group differences in compulsion subscale scores. Complete response was also more frequent in the L-theanine group (P = 0.0001). CONCLUSION: Findings in this study suggest L-theanine as a relatively safe and effective adjuvant therapy for moderate to severe OCD.

Knowledge, attitude, and practice regarding child maltreatment amongst Iranian medical students through internship course: an 18-month longitudinal study.

BACKGROUND: Child maltreatment has been a major worldwide problem and has remained a persistent public health challenge in all countries. Physicians have a significant role in the prevention and intervention of child maltreatment. An educated physician that can effectively identify and report child maltreatment can fill one of the most significant gaps in reducing child abuse. This study was performed to examine the knowledge, attitude, and practice regarding child maltreatment among Iranian medical students through an internship course. METHOD: All the medical students (235 students) of the Iran University of Medical Sciences who passed the internship entrance exam in the 2019-2020 academic year participated in this study. The participants completed a 49-item scale questionnaire built by combining three other validated questionnaires that evaluate their attitude, knowledge, and practice skills in the first month of their internship course and then completed the same questionnaire 18 months later, at the end-point of the internship period. RESULTS: One-hundred thirty nine (59.1%) participants were female, and 96 (40.9%) were male. The mean age of the subjects was 24.35 ± 0.76. Only 7 (3%) of them formerly received any education about child maltreatment. There was a significant improvement in scores of the knowledge of prevention (p-value = 0.001), the practice of prevention (p-value < 0.001) and the general subscale of the practice section (p-value < 0.001) during the internship course. However, the performance of participants decreased significantly in the subscales of the attitude towards diagnosis (p-value = 0.001) and the attitude towards reporting (p-value < 0.001) of child maltreatment. At the end of the study, the result of graduated physicians was: The total knowledge and attitude of participants were satisfactory, and the majority were at reasonable levels. Although in the practice subscale, 70.6% of the participants didn't identify, 84.7% didn't refer, and 86.4% didn't report a child abuse case in the past year. CONCLUSION: The knowledge and attitude of Iranian physicians regarding child maltreatment are at a satisfactory level. Although, the practice level has deficiencies. In addition, our findings show that Iranian interns have a shallow experience regarding child maltreatment, particularly despite the higher scores in attitude and knowledge, which can be the reason for deficiencies in the practice level.

Investigation of a group of Iranian theater artists' mental health and attitude toward patients with mental disorders.

Introduction: Stigmatizing attitude toward patients with severe mental disorders is one of the main obstacles of improving the mental health of societies. Media plays an important role in how the public views mental health issues. Thus, we have performed this study to investigate the Iranian theater artists' mental health status, and their view toward patients with severe mental disorders. Methods: This cross-sectional study was performed via an online anonymous survey including the Social Distance Scale and the Dangerousness Scale measuring the attitude of participants toward patients with severe mental disorders, and the 28-item General Health Questionnaire (GHQ-28). It was disseminated to artists who had the experience of working in theater in the past year in Iran. Results: Our survey was responded by 104 artists. Social Distance Scale scores' mean was 10.67 (scores can range from 0 to 21) and the Dangerousness Scale scores' mean was 28.87 (scores can range from 8 to 56); higher scores indicate worse discrimination. Our participants' strongest fears were to let someone with a severe mental disorder to take care of their children, and for these groups of patients to obtain a hunting license. Twenty-six (25%) participants were at risk of moderate to severe anxiety, and 18 (17.3%) participants were at risk of moderate to severe depression. Conclusion: By and large, our participants did not have a positive attitude toward patients with severe mental disorders. Providing the knowledge of mental health issues can help the general public to be more tolerant of the mentally ill and specifically, theater can be employed to fight stigmatizing mental health issues by educating its audience.

Online Sexual Activity among Iranian Clients with Borderline Personality Disorder and Its Correlation with Severity of Symptoms.

Objective: Clients with borderline personality disorder (BPD) often engage in high-risk sexual behaviors. Online sexual platforms convey abusive and harmful themes, especially for this group of sexually impulsive patients. We hypothesized a correlation between their online sexual activities and the severity of BPD symptoms. Method : Fifty clients with BPD who were referred to Iran psychiatric hospital and Tehran Psychiatric Institute in 2020 participated in this research. The Borderline Evaluation of Severity over Time (BEST) questionnaire was used to assess the severity of BPD symptoms, and the Internet Sex Screening Test (ISST) was used to evaluate online sexual behaviors. A psychiatric interview considered substance abuse and other confounding factors. Results: The mean ISST and BEST scores were 7.82 ± 5.74 and 41.7 ± 12.5, respectively. There was a positive and significant correlation between the severity of BPD symptoms and online sexual activities (P < 0.001, r = 0.480). There was also a significant relationship between online sexual activities and a history of substance abuse (P = 0.003, F = 25.06). Conclusion: Online sexual activity can harm clients with BPD who are more vulnerable to high-risk sexual behaviors. More severe borderline personality traits were associated with more online sexual activity, which underlines the importance of providing education about and managing such activities in clients with BPD.
