RESUMEN

There is little evidence for psychopharmacotherapy in pica. A few studies reported some benefit from the use of SSRIs, atypical antipsychotics and methylphenidate. That said, evidence to deploy these agents remains, at large, flimsy. Here, despite scarcity, we review available literature and draw some generalities that can inform decision-making on clinical grounds.

RESUMEN

Trazodone is a serotonin antagonist/reuptake inhibitor, approved for treating major depressive disorder (MDD). Oral formulations are widely studied and marketed in several countries worldwide while there is little evidence to support use of parenteral formulation. Our narrative review summarizes pharmacological properties and clinical data concerning use of parenteral trazodone in mood disorders. PubMed and Web of Science were used to identify the most relevant literature. The main evidence concerns four studies evaluating efficacy in major depressive disorder and indicates that trazodone was well tolerated and effective. Off-label use in agitation associated with bipolar disorder is also reported in three studies, although prescription of concomitant treatment, as a confounding factor, may have influenced outcome measures. The limited available evidence supports parenteral trazodone use in major depressive disorder and suggests that trazodone is a suitable option in patients at high risk of treatment-emergent mania (TEM).

RESUMEN

The main hurdles with current therapies for major depressive disorder (MDD) include lack of efficacy, therapeutic latency, and adverse drug reactions. Add-on therapy to conventional antidepressants may result in better therapeutic outcomes to overcome these obstacles. Sarcosine (N-methyl glycine), an endogenous amino acid that acts by modulating the NMDA receptor, is available as a dietary supplement. So, the present study was planned to evaluate the efficacy and safety of add-on sarcosine to SSRIs in MDD. In the present randomized, double-blind clinical trial (NCT04975100), 60 eligible participants with MDD were randomly assigned to either the test group (SSRI + sarcosine) or the control group (SSRI + placebo). Clinical and biochemical parameters like MADRS, CGI, serum BDNF, and serum glycine were assessed at baseline and eight weeks. The mean reduction in MADRS score was significant in both the control (-8.7, 95% CI: -11.0 to -6.4, p < 0.001) and the test group (-13.3, 95% CI: -14.9 to -11.7, p < 0.001), but the change in the test group was significantly greater (-4.6, 95% CI: -7.5 to -1.7, p = 0.003). The test group had a significantly higher response rate (p = 0.007) and remission rate (p = 0.038) compared to the control group. There was a significant increase in serum BDNF in both groups; however, the change in the test group was significantly higher than in the control group (p = 0.041). Similarly, the test group had a significantly higher increase in serum glycine than the control group (p < 0.001). Sarcosine may be considered an efficacious and safe add-on therapy to standard SSRIs in the management of MDD. ClinicalTrial.gov IdentifierNCT04975100.

RESUMEN

BACKGROUND AND OBJECTIVES: Animal studies have suggested a link between benzodiazepine and related Z-drug (BZDR) use and immune dysfunction. Corresponding evidence in humans is limited and focuses mainly on pneumonia. This study aimed to assess the association of incident BZDR use with subsequent development of serious infections. METHODS: This Swedish register-based study included a population-based demographically matched cohort, a co-twin control cohort, and an active comparator cohort. Out of 7,362,979 individuals aged below 65 years who were BZDR naïve by 2007, 713,896 BZDR recipients with incident dispensation of any BZDRs between 2007 and 2019 were 1:1 matched to 713,896 nonrecipients from the general population; 9197 BZDR recipients were compared with their 9298 unexposed co-twins/co-multiples; and 434,900 BZDR recipients were compared with 428,074 incident selective serotonin reuptake inhibitor (SSRI) recipients. The outcomes were identified by the first inpatient or specialist outpatient diagnosis of serious infections in the National Patient Register, or death from any infections recorded as the underlying cause in the Cause of Death Register. Cox proportional hazards regression models were fitted and controlled for multiple confounders, including familial confounding and confounding by indication. To study a possible dose-response association, the cumulative dosage of BZDRs dispensed during the follow-up was estimated for each BZDR recipient and modeled as a time-varying exposure with dose categories in tertiles [≤ 20 defined daily doses (DDDs), > 20 DDDs ≤ 65, and > 65 DDDs). The risk of infections was assessed in BZDR recipients within each category of the cumulative BZDR dosage compared to their demographically matched nonrecipients. RESULTS: In the demographically matched cohort (average age at incident BZDR use 42.8 years, 56.9% female), the crude incidence rate of any serious infections in BZDR recipients and matched nonrecipients during 1-year follow-up was 4.18 [95% confidence intervals (CI) 4.13-4.23] and 1.86 (95% CI 1.83-1.89) per 100 person-years, respectively. After controlling for demographic, socioeconomic, clinical, and pharmacological confounders, BZDR use was associated with 83% relative increase in risk of any infections [hazard ratio (HR) 1.83, 95% CI 1.79-1.89]. The risk remained increased, although attenuated, in the co-twin cohort (HR 1.55, 95% CI 1.23-1.97) and active comparator cohort (HR 1.33, 95% CI 1.30-1.35). The observed risks were similar across different types of initial BZDRs and across individual BZDRs, and the risks increased with age at BZDR initiation. We also observed a dose-response association between cumulative BZDR dosage and risk of serious infections. CONCLUSIONS: BZDR initiation was associated with increased risks of serious infections, even when considering unmeasured familial confounding and confounding by indication. The exact pathways through which BZDRs may affect immune function, however, remain unclear. Further studies are needed to explore the neurobiological mechanisms underlying the association between BZDR use and serious infections, as it can lead to safer therapeutic strategies for patients requiring BZDR.

RESUMEN

INTRODUCTION AND OBJECTIVES: Selective serotonin reuptake inhibitors (SSRIs) are medications used in child and adolescent psychiatry mainly for the treatment of depression, anxiety and obsessive compulsive disorder. In general, these medications are safe and well tolerated. However, they can cause adverse effects such as activation syndrome, which if not identified can negatively affect adherence and response to treatment. Activation syndrome has received little attention and can be difficult to recognise due to the lack of a clear definition and objective diagnostic measures, and also because it can be confused with a worsening of the psychiatric disorder or mania triggered by the antidepressants. For all the above, it is important that professionals who prescribe antidepressants in the paediatric population are able to identify and manage activation syndrome when it occurs. Our aim was to carry out a narrative review of activation syndrome in children and adolescents treated with SSRIs in terms of definition, prevalence, pathophysiology, associated factors, relationship with suicide risk, management strategies and recommendations for reducing the risk of suicidal behaviours when using antidepressants in this population. METHODS: We performed a non-systematic narrative review of activation syndrome in children and adolescents which involved finding information in PubMed, Ovid, EBSCO, ProQuest and Embase. Review articles, prospective and retrospective investigations, systematic reviews, meta-analyses and other articles related to activation syndrome in children and adolescents were selected. The search was limited to studies published in English and Spanish that involved children and adolescents and no limits were applied to the publication date or study design. RESULTS: A total of 62 articles were included, 61 of them in English. The results were grouped into the following topics: definition; prevalence; pathophysiology; associated factors; relationship with suicide risk; management strategies; and recommendations for reducing the risk of suicidal behaviours when using antidepressants in this population. Activation syndrome refers to a set of symptoms consisting of impulsiveness, restlessness, increased activity, insomnia, irritability, disinhibition and agitation. This syndrome is poorly characterised in terms of its definition, prevalence, risk factors and pathophysiology, a situation that limits its recognition and evaluation. There are many factors that predispose the development of the syndrome such as age, differences in brain development in the paediatric population, the characteristics of the patient or the antidepressant, disorders of neurological development, and the doses and plasma levels of the medications. It has been thought that activation syndrome may be related to suicidal tendencies. However, the evidence in support of this link is inconsistent and further studies are therefore necessary. CONCLUSIONS: Activation syndrome with SSRI is a particularly important adverse effect in children and adolescents and, when it occurs, can cause lack of adherence to or discontinuation of treatment. Strict vigilance is therefore recommended during the use of these medications.

RESUMEN

BACKGROUND: Fluoxetine is present in breast milk, yet it is unclear to what extent it, or its active metabolite, norfluoxetine, reaches the brain of the infant and what the effects of such exposure on neurobiological processes are. We therefore aimed to quantify the concentration of passively administered fluoxetine and norfluoxetine in the whole brains of exposed Flinders sensitive line (FSL) offspring and establish their influence on serotonergic function and redox status. METHODS: Adult FSL dams received fluoxetine (10 mg/kg/day), or placebo for fourteen days, beginning on postpartum day 04. Offspring were passively exposed to fluoxetine until postnatal day 18 and euthanized on postnatal day 22. Whole brain fluoxetine, norfluoxetine, serotonin (5-HT), 5-hydroxyindoleacetic acid (5-HIAA), and reduced (GSH) and oxidized glutathione (GSSG) concentrations were measured via liquid chromatography-mass spectrometry (LC-MS) analysis. RESULTS: Whole-brain serotonin and 5-hydroxyindoleacetic acid concentrations, and serotonin turnover (5-HIAA/5-HT) were comparable between strains. Treatment-naïve FSL rats had lower GSH and higher GSSG whole-brain concentrations, relative to FRL controls, and an overall decreased GSH/GSSG ratio. Passively administered fluoxetine resulted in undetectable whole-brain concentrations, while norfluoxetine averaged 41.28 ± 6.47 ng/g. Serotonin turnover of FSL rats was unaffected by passively administered fluoxetine, while redox status (GSH/GSSG) was decreased. CONCLUSION: Our findings confirm that passively administered fluoxetine reaches the infant brain in the form of norfluoxetine and may manipulate processes of oxidative stress regulation. Further studies into the long-term bio-behavioural effects are however needed to effectively inform breast feeding mothers on the safety of antidepressant-use.

RESUMEN

OBJECTIVE: In this retrospective cohort study, we compared neonatal and maternal outcomes after exposure of different psychopharmacological classes of drugs. Both psychiatric diseases and pharmacological treatment of these are associated with lower birth weights, lower APGAR scores, and NICU admission. Therefore, we tried to rule out the role of psychotropics as if no differences were found between pharmacological classes, the lower birthweights might not be attributable to these. METHOD: We divided our groups in exposed to atypical antipsychotic drugs, Selective Serotonin Reuptake Inhibitors (SSRI), Tricyclic Antidepressants (TCA), benzodiazepines, and different combinations of psychotropic drugs. The last group included SSRIs combined with benzodiazepines, methylphenidate, lithium, and classic antipsychotic drugs. RESULTS: We used univariate regression analysis to see which factors from our rich dataset including pharmacological class, are associated with birth weight, APGAR scores, gestational age, and NICU admission. The significant associations from univariate analyses were further analyzed using ancova analysis or logistic regression where applicable. CONCLUSION: We found no clinically relevant differences in neonatal and maternal outcomes between the different exposed pharmacological classes. However, our dataset may have been too small to draw firm conclusions.

RESUMEN

The role of cerebellar-cerebral functional connectivity (CC-FC) in obsessive-compulsive disorder (OCD), its trajectory post-pharmacotherapy, and its potential as a prognostic biomarker and genetic mechanism remain uncertain. To address these gaps, this study included 37 drug-naive OCD patients and 37 healthy controls (HCs). Participants underwent baseline functional magnetic resonance imaging (fMRI), followed by four weeks of paroxetine treatment for patients with OCD, and another fMRI scan post-treatment. We examined seed-based CC-FC differences between the patients and HCs, and pre- and post-treatment patients. Support vector regression (SVR) based on CC-FC was performed to predict treatment response. Correlation analysis explored associations between CC-FC and clinical features, as well as gene profiles. Compared to HCs, drug-naive OCD patients exhibited reduced CC-FC in executive, affective-limbic, and sensorimotor networks, with specific genetic profiles associated with altered CC-FC. Gene enrichment analyses highlighted the involvement of these genes in various biological processes, molecular functions, and pathways. Post-treatment, the patients showed partial clinical improvement and partial restoration of the previously decreased CC-FC. Abnormal CC-FC at baseline correlated negatively with compulsions severity and social functional impairment, while changes in CC-FC correlated with cognitive function changes post-treatment. CC-FC emerged as a potential predictor of symptom severity in patients following paroxetine treatment. This longitudinal resting-state fMRI study underscores the crucial role of CC-FC in the neuropsychological mechanisms of OCD and its pharmacological treatment. Transcriptome-neuroimaging spatial correlation analyses provide insight into the neurobiological mechanisms underlying OCD pathology. Furthermore, SVR analyses hold promise for advancing precision medicine approaches in treating patients with OCD.

RESUMEN

No study has determined the minimal effective dose of trazodone required to induce behavioral changes and its safety profile in rabbits. Therefore, this study aimed to determine the minimal effective dose of trazodone to improve compliance to handling, and to evaluate associated changes in motor activity, physiological and arterial blood gas parameters. Eight intact female New Zealand White rabbits (2-month-old; 1.66 ± 0.12 kg) were included in this prospective, blinded, randomized cross-over study. After a 10-day acclimation, rabbits randomly received placebo or trazodone 10, 20 or 30 mg/kg orally (PLAC, TRAZ10, TRAZ20, TRAZ30) with a 1-week wash-out period. Compliance scoring (dynamic interactive visual analog scale; DIVAS), activity levels measured with accelerometry (T0-T600), physiological parameters (temperature, heart, and respiratory rates), and arterial blood gas parameters (up to T240) were evaluated. Compliance scores, accelerometry, physiological and arterial blood gas parameters and hypoxemia prevalence (PaO2 <60 mmHg) were analyzed using linear mixed models and Chi-squared tests, respectively (P<0.05). When compared with PLAC, DIVAS scores were significantly higher at T80-120, T40-120 and T120-200 in TRAZ10, TRAZ20 and TRAZ30 post-administration, respectively. When compared with baseline, DIVAS scores were significantly higher from T80-160, T40-240 and T80-200 in TRAZ10, TRAZ20 and TRAZ30, respectively. All other parameters were not significantly different. In TRAZ30, hypoxemia was observed in 2/8 rabbits (P=0.104). In conclusion, oral trazodone improved rabbit compliance at all studied dosages, especially 20 mg/kg improved rabbit compliance without decreasing motor activity or causing hypoxemia.

RESUMEN

RATIONALE: Selective serotonin reuptake inhibitors (SSRIs) are the first choice of treatment for anxiety-like disorders. However, which aspects of anxiety are affected by SSRIs is not yet fully understood. OBJECTIVE: We aimed to systematically review the effect of six clinically effective SSRIs on four aspects of unconditioned anxiety: approach-avoidance behaviour (elevated plus maze), repetitive behaviour (marble burying), distress behaviour (ultrasonic vocalization), and activation of the autonomous nervous system (stress-induced hyperthermia). METHODS: We identified publications by searching Medline and Embase databases and assessed the risk of bias. A random effects meta-analysis was performed and moderator effects were analysed with Bayesian penalized meta-regression. RESULTS: Our search yielded 105 elevated plus maze, 63 marble burying, 11 ultrasonic vocalization, and 7 stress-induced hyperthermia articles. Meta-analysis suggested that SSRIs reduce anxiety-like behaviour in the elevated plus maze, marble burying and ultrasonic vocalization test and that effects are moderated by pre-existing stress conditions (elevated plus maze) and dose dependency (marble burying) but not by duration of treatment or type of SSRI. The reporting quality was low, publication bias was likely, and heterogeneity was high. CONCLUSION: SSRIs seem to reduce a broad range of unconditioned anxiety-associated behaviours. These results should be interpreted with caution due to a high risk of bias, likely occurrence of publication bias, substantial heterogeneity and limited moderator data availability. Our review demonstrates the importance of including bias assessments when interpreting meta-analysis results. We further recommend improving the reporting quality, the conduct of animal research, and the publication of all results regardless of significance.

RESUMEN

The objective of this study was to establish the pharmacokinetics of a single oral dose of trazodone in the Hispaniolan Amazon parrot (Amazona ventralis). Trazodone is a selective serotonin antagonist and reuptake inhibitor used commonly in both human and veterinary medicine as an antidepressant behavioral modification medicine. A single oral dose of compounded trazodone hydrochloride solution (20 mg/mL) at 50 mg/kg was administered to a total of 7 healthy adult Hispaniolan Amazon parrots. The 7 healthy adult parrots ranged in age from 10 to 15 years and weighed 228 to 323g. Blood was collected at baseline (2 weeks before study) and at 1, 2, 4, 6, 10, and 14 hours post-drug administration. Plasma concentrations of both trazodone and its active metabolite m-chlorophenylpiperazine (mCPP) were measured via liquid chromatography tandem mass spectrometry. Noncompartmental pharmacokinetic analysis was completed. The half-life (t1/2) ± SD of trazodone for the Hispaniolan parrots was 1.89 ± 0.49 hours, and the t1/2 ± SD of mCPP metabolite was 1.9 ± 0.55 hours. Maximum serum drug concentrations, or Cmax (ng/mL), were 738.3 ± 285.3 for trazodone. Times to achieve Cmax (hours) for trazadone and the mCPP metabolite were 1 hour and 2 hours postdosing, respectively. While this study did not establish the behavioral effects of trazodone, no adverse side effects were observed throughout the 48-hour period following drug administration and blood collection. Our results indicate that the oral administration of a 50-mg/kg single dose of trazodone to Hispaniolan parrots may be considered a safe dose. Plasma concentrations are comparable to previously published values in humans, dogs, horses, and pigeons (Columba livia domestica) for up to 14 hours following dosing. This study indicates that further studies are needed to establish the pharmacodynamics and the efficacy of trazodone in the medical management of behavioral problems in psittacine species.

RESUMEN

BACKGROUND: Health-related quality of life (HRQL) is an important goal for patients with major depressive disorder (MDD), but whether antidepressants improve HRQL in these patients is unclear. Here, we describe the real-world effects of trazodone once-a-day (TzOAD) and selective serotonin reuptake inhibitor (SSRI) treatments on HRQL and functioning in adults with MDD. METHODS: This 8-week prospective, observational, open-label, multicenter study was conducted in adults with moderate or severe MDD for whom TzOAD or SSRI were prescribed as monotherapy. The primary outcome was life enjoyment and satisfaction assessed via the patient-reported Quality-of-Life Enjoyment and Satisfaction Questionnaire Short Form (Q-LES-Q-SF) from baseline to week 8. Secondary outcomes included change in Q-LES-Q-SF from baseline to weeks 1 and 2; severity of depressive symptoms using the Montgomery Åsberg Depression Rating Scale (MADRS) and sleep disturbance via the PROMIS SF-SD 8b questionnaire at weeks 1, 2, and 8; and overall functioning via the Sheehan Disability Scale (SDS), hedonic capacity using the Snaith-Hamilton Pleasure Scale (SHAPS), and cognitive dysfunction using the Perceived Deficits Questionnaire (PDQ-5) at baseline and week 8. RESULTS: The study included 208 adults with MDD (mean [SD] age = 50.2 [14.3] years; 68.6% female; 98.4% White). Life enjoyment and satisfaction improved from baseline to week 8 for both treatment groups: Q-LES-Q-SF mean (SD) scores were 27.5 (20.4) for the SSRI group and 39.0 (22.1) for the TzOAD group. Depressive symptoms and sleep disturbances also reduced from baseline to week 8: MADRS (SSRI, -15.7 [8.3]; TzOAD, -21.0 [9.8]); PROMIS SF-SD 8b (SSRI, -9.9 [12.6]; TzOAD, -22.0 [12.6]). Mean change scores in Q-LES-Q-SF, MADRS, and PROMIS SF-SD 8b improved as early as week 1 in both groups. Mean scores also improved from baseline to week 8 on SDS (SSRI, -9.2 [7.4]; TzOAD, -14.3 [7.5]), SHAPS (SSRI, -6.6 [4.3]; TzOAD, -8.3 [4.4]), and PDQ-5 (SSRI, -5.8 [4.5]; TzOAD, -7.7 [5.0]). CONCLUSIONS: In adults with MDD who received TzOAD or SSRIs, overall and individual HQRL domains improved rapidly and in parallel with improvements in depressive symptoms, with a slightly greater improvement observed in the TzOAD group.

RESUMEN

Chronic treatment with clomipramine, a tricyclic antidepressant drug, reduces symptoms of obsessive-compulsive disorder (OCD) and can influence the activity of the hypothalamic-pituitary-adrenal axis. However, little is known regarding the effects of acute clomipramine on the immediate expression of stress responses. Serotonergic drugs can elicit surfacing, a behavioral profile potentially related to toxicity in fish, although surfacing has not yet been observed after clomipramine exposure. The present study investigated the impact of acute exposure to clomipramine on basal and stress-induced behaviors in the novel tank test and cortisol levels in mixed-sex, wild-type, adult zebrafish (Danio rerio). The findings show clomipramine-exposed groups (regardless of stress exposure) spent much more time in the top of the novel tank and had significantly less overall motor activity in the behavioral task compared to the fish not exposed to the drug. Then, the dose-dependent effects of acute clomipramine on activity in the surface of the novel tank (top third of the top half) were investigated further. Clomipramine dose-dependently increased surface-dwelling and elicited a dose-dependent hypoactivity in overall motor behavior. There were no statistically significant differences in whole-body cortisol levels in either experiment. Like other serotonin-acting drugs, clomipramine strongly elicited surface-dwelling and depressed motor behavior in adult zebrafish. Additional testing is needed to elucidate whether surfacing represents a toxic state and how serotonin regulates surfacing.

RESUMEN

BACKGROUND: There have only been two efficacy trials reporting a head-to-head comparison of medications and psychotherapy for PTSD, and neither was conducted in primary care. Therefore, this protocol paper describes a pragmatic trial that compares outcomes of primary care patients randomized to initially receive a brief trauma-focused psychotherapy or a choice of three antidepressants. In addition, because there are few trials examining the effectiveness of subsequent treatments for patients not responding to the initial treatment, this pragmatic trial also compares the outcomes of those switching or augmenting treatments. METHOD: Patients screening positive for PTSD (n = 700) were recruited from the primary care clinics of 7 Federally Qualified Health Centers (FQHC) and 8 Department of Veterans Affairs (VA) Medical Centers and randomized in the ratio 1:1:2 to one of three treatment sequences: 1) selective serotonin reuptake inhibitor (SSRI) followed by augmentation with Written Exposure Therapy (WET), 2) SSRI followed by a switch to serotonin-norepinephrine reuptake inhibitor (SNRI), or 3) WET followed by a switch to SSRI. Participants complete surveys at baseline, 4 months, and 8 months. The primary outcome is PTSD symptom severity as measured by the PTSD Checklist (PCL-5). RESULTS: Average PCL-5 scores (M = 52.8, SD = 11.1) indicated considerable severity. The most common bothersome traumatic event for VA enrollees was combat (47.8%), and for FQHC enrollees was other (28.2%), followed by sexual assault (23.4%), and child abuse (19.8%). Only 22.4% were taking an antidepressant at baseline. CONCLUSION: Results will help healthcare systems and clinicians make decisions about which treatments to offer to patients.

RESUMEN

There have been 774,075,242 cases of COVID-19 and 7,012,986 deaths worldwide as of January 2024. In the early stages of the pandemic, there was an urgent need to reduce the severity of the disease and prevent the need for hospitalization to avoid stress on healthcare systems worldwide. The repurposing of drugs to prevent clinical deterioration of COVID-19 patients was trialed in many studies using many different drugs. Fluvoxamine (an SSRI and sigma-1 receptor agonist) was initially identified to potentially provide beneficial effects in COVID-19-infected patients, preventing clinical deterioration and the need for hospitalization. Fourteen clinical studies have been carried out to date, with seven of those being randomized placebo-controlled studies. This systematic review and meta-analysis covers the literature from the outbreak of SARS-CoV-2 in late 2019 until January 2024. Search terms related to fluvoxamine, such as its trade names and chemical names, along with words related to COVID-19, such as SARS-CoV-2 and coronavirus, were used in literature databases including PubMed, Google Scholar, Scopus, and the ClinicalTrials.gov database from NIH, to identify the trials used in the subsequent analysis. Clinical deterioration and death data were extracted from these studies where available and used in the meta-analysis. A total of 7153 patients were studied across 14 studies (both open-label and double-blind placebo-controlled). 681 out of 3553 (19.17%) in the standard care group and 255 out of 3600 (7.08%) in the fluvoxamine-treated group experienced clinical deterioration. The estimated average log odds ratio was 1.087 (95% CI 0.200 to 1.973), which differed significantly from zero (z = 2.402, p = 0.016). The seven placebo-controlled studies resulted in a log odds ratio of 0.359 (95% CI 0.1111 to 0.5294), which differed significantly from zero (z = 3.103, p = 0.002). The results of this study identified fluvoxamine as effective in preventing clinical deterioration, and subgrouping analysis suggests that earlier treatment with a dose of 200 mg or above provides the best outcomes. We hope the outcomes of this study can help design future studies into respiratory viral infections and potentially improve clinical outcomes.

RESUMEN

Specific selective serotonin reuptake inhibitors (SSRIs) metabolism is strongly influenced by two pharmacogenes, CYP2D6 and CYP2C19. However, the effectiveness of prospectively using pharmacogenetic variants to select or dose SSRIs for depression is uncertain in routine clinical practice. The objective of this prospective, multicenter, pragmatic randomized controlled trial is to determine the effectiveness of genotype-guided selection and dosing of antidepressants on control of depression in participants who are 8 years or older with ≥3 months of depressive symptoms who require new or revised therapy. Those randomized to the intervention arm undergo pharmacogenetic testing at baseline and receive a pharmacy consult and/or automated clinical decision support intervention based on an actionable phenotype, while those randomized to the control arm have pharmacogenetic testing at the end of 6-months. In both groups, depression and drug tolerability outcomes are assessed at baseline, 1 month, 3 months (primary), and 6 months. The primary end point is defined by change in Patient-Reported Outcomes Measurement Information System (PROMIS) Depression score assessed at 3 months versus baseline. Secondary end points include change inpatient health questionnaire (PHQ-8) measure of depression severity, remission rates defined by PROMIS score < 16, medication adherence, and medication side effects. The primary analysis will compare the PROMIS score difference between trial arms among those with an actionable CYP2D6 or CYP2C19 genetic result or a CYP2D6 drug-drug interaction. The trial has completed accrual of 1461 participants, of which 562 were found to have an actionable phenotype to date, and follow-up will be complete in April of 2024.

RESUMEN

Background and aim: Prescription patterns of antidepressants have changed over the years with a shift towards newer antidepressants with better tolerability and safety. Polypharmacy is common in psychiatry settings. The study aimed to evaluate the antidepressant drug prescription pattern and polypharmacy in a psychiatry outpatient setting. Investigations: This prospective observational study was conducted in a psychiatric outpatient clinic. The medication use data of eligible patients were collected. In addition, the rationale of antidepressant medication prescription, the defined daily dosage (DDD), the prescribed daily dose (PDD), and the PDD to DDD ratio were assessed. The assessment of prescription polypharmacy was conducted utilizing the framework provided by the National Association of State Mental Health Program Directors. Results: Data from 131 patients was analyzed. Major depressive disorder (32.8%) was the most common disorder for which antidepressants were prescribed. The majority, 91 (69.4%), received monotherapy. Selective serotonin reuptake inhibitors were the most frequently prescribed drugs in 69 (52.7%). Mirtazapine was the most frequently 32(24.4%) prescribed drug. Escitalopram and mirtazapine were the most commonly prescribed combination therapy (4.6%). Antipsychotic medications (37.4%) were the most widely co-prescribed medications, along with antidepressants. The PDD to DDD ratio was less than 1 for mirtazapine and imipramine; they were ≥1 for others. Psychiatric polypharmacy was documented in 87.1% of prescriptions. The total polypharmacy was not significantly (p>0.05) associated with demographic, illness, and treatment-related variables. Conclusion: Selective serotonin reuptake inhibitors were the most commonly prescribed antidepressants, monotherapy, and combination therapy. A substantial amount of patients received concomitant administration of antidepressants or psychotropic drugs, warranting careful monitoring.

RESUMEN

Objective: Major depressive disorder (MDD) presents a significant psychosocial burden, and there is an unmet need for additional treatment options in pediatric patients. Here, we report the results of two phase 3 multicenter, randomized, double-blind, placebo- and active-controlled, parallel-group studies evaluating the efficacy and safety of levomilnacipran extended release in children and adolescents with MDD. Methods: In the first study, LVM-MD-11, patients aged 12-17 years received daily doses of levomilnacipran 40 mg (n = 134), levomilnacipran 80 mg (n = 138), fluoxetine 20 mg (n = 134), or placebo (n = 141). In the second study, LVM-MD-14, patients aged 7-17 years received levomilnacipran 40 to 80 mg (n = 166), fluoxetine 20 mg (n = 166), or placebo (n = 160) daily. Primary and secondary efficacy endpoints were changes in Children's Depression Rating Scale-Revised (CDRS-R) total score and Clinical Global Impressions-Severity (CGI-S) score, respectively. Results: In LVM-MD-11, there were no significant differences in change in CDRS-R total score between patients treated daily with placebo (least squares mean [LSM] change in CDRS-R total score -22.9) versus levomilnacipran 40 mg (-23.3; p = 0.8035) or 80 mg (-22.6; p = 0.8681). Similarly, in LVM-MD-14, there were no significant differences in LSM change in CDRS-R total score with placebo (-21.3) versus levomilnacipran 40 to 80 mg daily (-23.0; p = 0.2215). There were also no significant differences between the fluoxetine and placebo groups in either study for changes in CDRS-R total score. Changes in CGI-S score were not significant between placebo and levomilnacipran 40 to 80 mg daily or between placebo and fluoxetine. Levomilnacipran was generally well tolerated. Conclusions: The high placebo response in this study prevented the detection of an effect of levomilnacipran in children and adolescents. Clinical Trial Registration numbers: NCT02431806 and NCT03569475.

RESUMEN

OBJECTIVE: To examine the long-term safety and tolerability of off-label high-dose serotonin reuptake inhibitors (OLHD-SRIs) in the treatment of obsessive-compulsive disorder (OCD). METHODS: A retrospective longitudinal study was performed on 105 randomly selected outpatients diagnosed with OCD and were treated with OLHD-SRIs for at least 6 months. Patients received sertraline >200 mg/day, escitalopram >20 mg/day, fluvoxamine >300 mg/day, and fluoxetine >60 mg/day, combined with exposure and response prevention therapy. Patients were divided into three dosing groups: sertraline equivalent dose (SED) ≤ 200 mg/day (n = 26, 24.7%), 201-400 mg/day (n = 51, 48.5%) and 401-650 mg/day (n = 28, 26.6%). Safety and tolerability were assessed with an electrocardiogram, blood biochemistry, complete blood count, and side-effects monitoring. RESULTS: SED ranged from 100 to 650 mg/day and the mean duration of OLHD-SRI treatment was 20.8 months. The most common side-effects reported were sexual dysfunction (n = 36, 34%), weight gain (n = 28, 27%), sedation (n = 27, 26%), hyperhidrosis (n = 20, 19%), and tremor (n = 11, 10%). Abnormal ECG was documented in one patient, and another patient experienced a first-time seizure, whereas elevated liver enzymes were seen in 4.8% of the sample (n = 5). None of the patients had serotonin syndrome or drug-induced liver injury. Side-effects did not differ among the three dosing groups. CONCLUSION: OLHD-SRIs appear to be safe and well tolerated in OCD patients in SED ≤ 650 mg/day doses and the side-effects did not differ between the three dosing groups.
