Sertraline with desvenlafaxine and sertraline with mirtazapine as treatment initiation in MDD patients with moderate to severe depression and effect on inflammatory markers

BACKGROUND

This study evaluated the effect of sertraline with desvenlafaxine and sertraline with mirtazapine on HAM-D score and inflammatory markers (IL-6 and TNF-α levels) in major depressive disorder.

METHODS

Patients (18-60 years) with MDD diagnosed by DSM-V criteria and HAM-D score 18 or more were included (n = 60). Group A patients (n = 30) received sertraline 50 mg/day and desvenlafaxine 50 mg/day. Group B patients (n = 30) received sertraline 50 mg/day and mirtazapine 30 mg/day. All patients were followed up for 8 weeks for the evaluation of clinical efficacy, safety, serum IL-6, and TNF-α levels.

RESULTS

Our study showed a comparatively similar and statistically significant (p < 0.05) reduction in HAM-D score in both groups in the 4th and 8th week of the treatment. Both drug combinations significantly (p < 0.05) decreased serum IL-6 and TNF-α after 8 weeks of treatment.

CONCLUSION

The present study suggests that the combination therapy (as treatment initiation) with sertraline and desvenlafaxine, and sertraline with mirtazapine is effective and well tolerated in MDD patients with moderate to severe depression, and their therapeutic efficacy is accompanied by decreased inflammatory markers (serum IL-6 and TNF-α).

The Role of Serotonin in Breast Cancer Stem Cells

Breast tumors were the first tumors of epithelial origin shown to follow the cancer stem cell model. The model proposes that cancer stem cells are uniquely endowed with tumorigenic capacity and that their aberrant differentiation yields non-tumorigenic progeny, which constitute the bulk of the tumor cell population. Breast cancer stem cells resist therapies and seed metastases; thus, they account for breast cancer recurrence. Hence, targeting these cells is essential to achieve durable breast cancer remissions. We identified compounds including selective antagonists of multiple serotonergic system pathway components required for serotonin biosynthesis, transport, activity via multiple 5-HT receptors (5-HTRs), and catabolism that reduce the viability of breast cancer stem cells of both mouse and human origin using multiple orthologous assays. The molecular targets of the selective antagonists are expressed in breast tumors and breast cancer cell lines, which also produce serotonin, implying that it plays a required functional role in these cells. The selective antagonists act synergistically with chemotherapy to shrink mouse mammary tumors and human breast tumor xenografts primarily by inducing programmed tumor cell death. We hypothesize those serotonergic proteins of diverse activity function by common signaling pathways to maintain cancer stem cell viability. Here, we summarize our recent findings and the relevant literature regarding the role of serotonin in breast cancer.

Psychotropic drugs upregulate aquaporin-2 via vasopressin-2 receptor/cAMP/protein kinase A signaling in inner medullary collecting duct cells

Psychotropic drugs may be associated with hyponatremia, but an understanding of how they induce water retention in the kidney remains elusive. Previous studies have postulated that they may increase vasopressin production in the hypothalamus without supporting evidence. In this study, we investigated the possibility of drug-induced nephrogenic syndrome of inappropriate antidiuresis using haloperidol, sertraline, and carbamazepine. Haloperidol, sertraline, or carbamazepine were treated in inner medullary collecting duct (IMCD) suspensions and primary cultured IMCD cells prepared from male Sprague-Dawley rats. The responses of intracellular cAMP production, aquaporin-2 (AQP2) protein expression and localization, vasopressin-2 receptor (V2R) and AQP2 mRNA, and cAMP-responsive element-binding protein (CREB) were tested with and without tolvaptan and the protein kinase A (PKA) inhibitors H89 and Rp-cAMPS. In IMCD suspensions, cAMP production was increased by haloperidol, sertraline, or carbamazepine and was relieved by tolvaptan cotreatment. In primary cultured IMCD cells, haloperidol, sertraline, or carbamazepine treatment increased total AQP2 and decreased phosphorylated Ser261-AQP2 protein expression. Notably, these responses were reversed by cotreatment with tolvaptan or a PKA inhibitor. AQP2 membrane trafficking was induced by haloperidol, sertraline, or carbamazepine and was also blocked by cotreatment with tolvaptan or a PKA inhibitor. Furthermore, upregulation of V2R and AQP2 mRNA and phosphorylated CREB was induced by haloperidol, sertraline, or carbamazepine and was blocked by tolvaptan cotreatment. We conclude that, in the rat IMCD, psychotropic drugs upregulate AQP2 via V2R-cAMP-PKA signaling in the absence of vasopressin stimulation. The vasopressin-like action on the kidney appears to accelerate AQP2 transcription and dephosphorylate AQP2 at Ser261.NEW & NOTEWORTHY It is unclear whether antipsychotic drugs can retain water in the kidney in the absence of vasopressin. This study demonstrates that haloperidol, sertraline, and carbamazepine can produce nephrogenic syndrome of inappropriate antidiuresis because they directly upregulate vasopressin-2 receptor and aquaporin-2 (AQP2) via cAMP/PKA signaling. We showed that, in addition to AQP2 trafficking, AQP2 protein abundance was rapidly increased by treatment with antipsychotic drugs in association with dephosphorylation of AQP2 at Ser261 and accelerated AQP2 transcription.

Therapeutic effects of sertraline on improvement of Ovariectomy-induced decreased spontaneous activity in mice

We have already reported that ovariectomized (OVX) rats reduced the spontaneous activity during the dark period due to the decease of serotonin release in the amygdala. In this study, we examined the potential of sertraline, a selective serotonin reuptake inhibitor, on the recovery of less spontaneous activity seen in mice with OVX-induced despair-like behaviors. Female 9-week old ICR mice were underwent either OVX or sham surgery. Sertraline (10 mg/kg/day, s.c.) or saline were started to administer to each group for 8 weeks (6 times/week) from the 8th week after OVX. Each spontaneous activity of mouse was evaluated during the dark period (19:00-07:00) using an infrared sensor. Moreover, mRNA expression levels of tryptophan hydroxylase (TPH) and X-box binding protein 1 (XBP1) were measured in the hippocampus and prefrontal cortex using by a real-time PCR method. We found out that the OVX-induced despair-like behaviors were improved by the continuous administration of sertraline. After treatment of OVX, our real-time PCR data showed that sertraline significantly suppressed the upregulation of XBP1 expression levels in both hippocampus and prefrontal cortex, although this suppression of the downregulation of TPH expression levels was seen in only hippocampus. These results suggest that sertraline improves the decrease in spontaneous activity induced by OVX assessed by the hippocampus suppressing decreased serotonin synthesis in the serotonergic neuron.

Prolonged Exposure and Sertraline Treatments for Posttraumatic Stress Disorder Also Improve Multiple Indicators of Social Functioning

Trauma survivors with posttraumatic stress disorder (PTSD) frequently also suffer from difficulties in social functioning that range across emotional, cognitive, and environmental domains. A detailed evaluation of the differential impacts of effective PTSD treatments on social functioning is needed. Men and women (N = 200) with chronic PTSD received 10 weeks of prolonged exposure (PE) or sertraline in a randomized clinical trial and were followed for 24 months. A secondary data analysis examined changes in social functioning with regard to fear of intimacy; receipt of social support; and distress, avoidance, and negative cognitions in social situations. Effects were examined between treatments over time, controlling for baseline functioning. There were large, durable improvements across all indices. Compared to sertraline, PE was more efficient at reducing fear of intimacy and distress from negative social cognitions by posttreatment, ds = 0.94-1.14. Patients who received sertraline continued to improve over the course of follow-up, ds = 0.54-1.17. The differential speed of therapeutic effects may argue for more direct mechanisms in cognitive behavioral interventions versus cascade effects in serotonin reuptake inhibitors. Notably, both treatments produced substantial social benefits for trauma survivors with social functioning difficulties, and effect sizes were comparable to typical reductions in PTSD, depression, and anxiety.

The efficacy of a coordinated pharmacological blockade in glioblastoma stem cells with nine repurposed drugs using the CUSP9 strategy

PURPOSE

Constructed from a theoretical framework, the coordinated undermining of survival paths in glioblastoma (GBM) is a combination of nine drugs approved for non-oncological indications (CUSP9; aprepitant, auranofin, captopril, celecoxib, disulfiram, itraconazole, minocycline, quetiapine, and sertraline) combined with temozolomide (TMZ). The availability of these drugs outside of specialized treatment centers has led patients to embark on combination treatments without systematic follow-up. However, no experimental data on efficacy using the CUSP9 strategy in GBM have been reported.

METHODS

Using patient-derived glioblastoma stem cell (GSC) cultures from 15 GBM patients, we described stem cell properties of individual cultures, determined the dose-response relationships of the drugs in the CUSP9, and assessed the efficacy the CUSP9 combination with TMZ in concentrations clinically achievable. The efficacy was evaluated by cell viability, cytotoxicity, and sphere-forming assays in both primary and recurrent GSC cultures.

RESULTS

We found that CUSP9 with TMZ induced a combination effect compared to the drugs individually (p < 0.0001). Evaluated by cell viability and cytotoxicity, 50% of the GSC cultures displayed a high sensitivity to the drug combination. In clinical plasma concentrations, the effect of the CUSP9 with TMZ was superior to TMZ monotherapy (p < 0.001). The Wnt-signaling pathway has been shown important in GSC, and CUSP9 significantly reduces Wnt-activity.

CONCLUSIONS

Adding experimental data to the theoretical rationale of CUSP9, our results demonstrate that the CUSP9 treatment strategy can induce a combination effect in both treatment-naïve and pretreated GSC cultures; however, predicting response in individual cultures will require further profiling of GSCs.

The Association of Baseline Suicidality With Treatment Outcome in Psychotic Depression

OBJECTIVE

To examine the association between baseline suicidality and outcome of major depression in a randomized controlled trial of the pharmacotherapy of psychotic depression and to explore the interaction of suicidality, randomized treatment assignment, and depression outcome.

METHODS

This study was a secondary analysis of data from 258 persons aged 18 years or older with DSM-IV-defined major depressive disorder with psychotic features who participated in a 12-week randomized controlled trial (RCT) comparing olanzapine plus sertraline with olanzapine plus placebo (the Study of the Pharmacotherapy of Psychotic Depression [STOP-PD], which ran from 2002 to 2007). The independent variable was baseline suicidality, defined by 4 groups (suicide attempt in the current episode, active suicidal ideation, passive suicidal ideation, and no suicidality). The outcome variables were change in 16-item Hamilton Depression Rating Scale (HDRS₁₆) total score (excluding the suicide item) over time and remission of psychotic depression over time.

RESULTS

Suicidality groups did not significantly differ on baseline HDRS₁₆ total score. Baseline suicidality group was significantly associated with change in HDRS₁₆ score over time in the sample as a whole (F₃,₁₃₉₄ = 8.17; P < .0001), but was not significantly associated with probability of remission over time. Among participants assigned to olanzapine and placebo, persons with no suicidality had a significantly greater reduction in HDRS₁₆ total score compared to those with passive suicidal ideation (7.5-point difference in change scores between the 2 groups; 95% CI, 4.3-10.7 t₁₃₉₄ = 4.61, P < .0001), active suicidal ideation (4.4 points; 95% CI, 1.4-7.4; t₁₃₉₄ = 2.85, P = .0176), or suicide attempts (6.1 points; 95% CI, 2.8-9.4; t₁₃₉₄ = 3.66, P = .0015). The 12-week change from baseline in HDRS₁₆ score for patients with no suicidality was not significantly different between the 2 treatment arms. However, the 12-week HDRS₁₆ improvement was significantly greater in the olanzapine plus sertraline arm, compared with the olanzapine plus placebo arm, for patients with suicide attempts (8.7-point difference in change scores between the 2 groups; 95% CI, 5.1-12.4; t₁₃₉₄ = 4.75, P < .0001), active suicidal ideation (8.1 points; 95% CI, 4.5-11.7; t₁₃₉₄ = 4.38, P < .0001), or passive suicidal ideation (5.7 points; 95% CI, 2.2-9.2; t₁₃₉₄ = 3.23, P = .0012), respectively.

CONCLUSIONS

Baseline suicidality predicted worse acute treatment outcome of psychotic depression. However, participants with suicidality had a better outcome when treated with the combination of olanzapine and sertraline than when treated with olanzapine plus placebo.

Do changes in trauma-related beliefs predict PTSD symptom improvement in prolonged exposure and sertraline?

OBJECTIVE

Negative trauma-related belief change has been found to predict subsequent improvement in symptoms of posttraumatic stress disorder (PTSD) in prolonged exposure (PE) and other therapies, consistent with several psychological theories of treatment change (e.g., Foa & Kozak, 1986). However, belief change has not been examined in selective serotonin reuptake inhibitors such as sertraline. We examined processes associated with symptom improvement in 2 treatments for PTSD, hypothesizing that belief change would robustly predict PTSD improvement in patients treated with PE but not those treated with sertraline, reflecting moderation by treatment.

METHOD

Patients with chronic PTSD (N = 134; 78% women, 71.6% Caucasian, M = 38.1 years, SD = 11.8) received 10 weeks of PE or sertraline in a randomized, controlled trial. Patients reported PTSD and depression symptoms, and trauma-related beliefs (Post-Traumatic Cognitions Inventory; Foa, Ehlers, Clark, D Tolin, & Orsillo, 1999) at pretreatment, every treatment session, and posttreatment.

RESULTS

Using time-lagged mixed regression models, change in trauma-related beliefs predicted subsequent PTSD symptom improvement, an effect moderated by treatment and particularly strong in PE (d = 0.93) compared with sertraline (d = 0.35). Belief change also predicted depressive symptom improvement but more modestly and bidirectionally, with no difference by treatment modality.

CONCLUSIONS

Trauma-related belief change precedes PTSD improvement more robustly in PE than in sertraline and with greater specificity compared with depressive symptoms. These findings highlight potentially divergent processes contributing to symptom change in these PTSD treatments, with belief change as a key mechanism of PE. (PsycINFO Database Record

High dose sertraline monotherapy fails to protect rhesus macaques from lethal challenge with Ebola virus Makona

The recent epidemic of Ebola virus disease in West Africa resulted in an unprecedented number of cases and deaths. Due to the scope of the outbreak combined with the lack of available approved treatment options, there was strong motivation to investigate any potential drug which had existing data reporting anti-Ebola activity. Drugs with demonstrated antiviral activity in the nonhuman primate models already approved for another indication or for which there was existing safety data were considered to be priorities for evaluation by the World Health Organization. Sertraline hydrochloride was reported to have anti-Ebola activity in vitro alone and in combination with other approved drugs. Although the efficacy was less than 100% in the murine model, the established safety profile of this product, the potential benefit alone and in combination, as well as the lack of other available options prioritized this compound for testing in the Ebola virus intramuscular rhesus macaque challenge model. Using a blinded dosing strategy, we demonstrated that high dose sertraline monotherapy provided no benefit for the prevention of Ebola virus disease in rhesus macaques with regards to reduction of viral load, morbidity, or survival highlighting the challenges of translating results between in vitro and in vivo models.

[Treating hoarding disorder in a 12-year-old boy]

In this case report hoarding disorder is described in a 12-year-old boy who suffered from obsessive collection of things. The disorder is a separate diagnostic entity in DSM-5, and it will probably be a separate disorder in ICD-11 called hoarding disorder. The disorder is generally considered difficult to treat, but this case report describes significant reduction in hoarding symptoms on cognitive behavioural therapy and treatment with selective serotonin reuptake inhibitors.

The effects of pharmaceuticals on a unionid mussel (Lampsilis siliquoidea): An examination of acute and chronic endpoints of toxicity across life stages

The toxicity and bioconcentration of 3 pharmaceuticals (amitriptyline, iopamidol, and sertraline) were examined using multiple life stages (larval, juvenile, and adult) of the unionid mussel Lampsilis siliquoidea. The endpoints examined varied with life stage but included survival, behavior (algal clearance rate, filtering frequency), and oxidative stress. Iopamidol was not toxic at concentrations up to 101 mg/L. Sertraline was the most toxic chemical (50% lethal concentrations [LC50] and effect concentrations [EC50] = 0.02-0.04 mg/L), but exposure did not induce oxidative stress. Glochidia and juveniles were more sensitive than adult mussels. Algal clearance rate in juvenile mussels was the most sensitive endpoint assessed, similar to or lower than the LC50 values for glochidia. However, the compounds examined were not toxic at concentrations detected in the environment. The relative bioconcentration factors were sertraline > amitriptyline > iopamidol. These results suggest that glochidia toxicity could be a screening tool for rapidly assessing the toxicity of chemicals of concern to freshwater mussels.

Sertraline use in the first trimester and risk of congenital anomalies: a systemic review and meta-analysis of cohort studies

AIM

To perform a meta-analysis of available cohort studies on the association between sertraline use by pregnant women in the first trimester and the findings of congenital anomalies in infants.

METHODS

A comprehensive search of articles published from the index date up to 31st December 2015 investigating the aforementioned associations was conducted on PubMed and Web of Science. Mesh headings used included the terms "serotonin reuptake inhibitor," "sertraline," "congenital anomalies" and "obstetrical outcome."

RESULTS

Twelve cohort studies that involved 6 468 241 pregnant women were identified. We summarized odds ratios (ORs) and 95% confidence intervals (CIs) of congenital anomalies using the random-effects model. Pregnant women who used sertraline in the first trimester had a statistically significant increased risk of infant cardiovascular-related malformations (OR = 1.36; 95% CI = 1.06-1.74; I2  = 64.4%; n = 12) as well as atrial and/or ventricular septal defects (OR = 1.36, 95% CI = 1.06-1.76; I2  = 62.2%; n = 8). Additionally, positive but nonsignificant associations between sertraline use and congenital anomalies of the nervous system (OR = 1.39; 95% CI = 0.83-2.32; I2  = 0%; n = 5), digestive system (OR = 1.23; 95% CI = 0.76-1.98; I2  = 0%; n = 5), eye, ear, face and neck (OR = 1.08; 95% CI = 0.33-3.55; I2  = 32.1%; n = 3), urogenital system (OR = 1.03; 95% CI = 0.73-1.46; I2  = 0%; n = 5), and musculoskeletal system (OR = 0.97; 95% CI = 0.69-1.36; I2  = 0%; n = 5) were observed.

CONCLUSION

This meta-analysis suggested that the use of sertraline use by pregnant women in the first trimester had an increased risk of cardiovascular-related malformations as well as atrial and/or ventricular septal defects in infants. Meanwhile, nonsignificant associations between sertraline use and other congenital anomalies were found. More cohort studies are warranted to provide detailed results of other congenital anomalies.

In Vitro Antifungal Activity of Sertraline and Synergistic Effects in Combination with Antifungal Drugs against Planktonic Forms and Biofilms of Clinical Trichosporon asahii Isolates

Trichosporon asahii (T. asahii) is the major pathogen of invasive trichosporonosis which occurred mostly in immunocompromised patients. The biofilms formation ability of T. asahii may account for resistance to antifungal drugs and results a high mortality rate. Sertraline, a commonly prescribed antidepressant, has been demonstrated to show in vitro and in vivo antifungal activities against many kinds of pathogenic fungi, especially Cryptococcus species. In the present study, the in vitro activities of sertraline alone or combined with fluconazole, voriconazole, itraconazole, caspofungin and amphotericin B against planktonic forms and biofilms of 21 clinical T. asahii isolates were evaluated using broth microdilution checkerboard method and XTT reduction assay, respectively. The fractional inhibitory concentration index (FICI) was used to interpret drug interactions. Sertraline alone exhibited antifungal activities against both T. asahii planktonic cells (MICs, 4–8 μg/ml) and T. asahii biofilms (SMICs, 16–32 μg/ml). Furthermore, SRT exhibited synergistic effects against T. asahii planktonic cells in combination with amphotericin B, caspofungin or fluconazole (FICI≤0.5) and exhibited synergistic effects against T. asahii biofilms in combination with amphotericin B (FICI≤0.5). SRT exhibited mostly indifferent interactions against T. asahii biofilms in combination with three azoles in this study. Sertraline-amphotericin B combination showed the highest percentage of synergistic effects against both T. asahii planktonic cells (90.5%) and T. asahii biofilms (81.0%). No antagonistic interaction was observed. Our study suggests the therapeutic potential of sertraline against invasive T. asahii infection, especially catheter-related T. asahii infection. Further in vivo studies are needed to validate our findings.

Study protocol: a phase III randomised, double-blind, parallel arm, stratified, block randomised, placebo-controlled trial investigating the clinical effect and cost-effectiveness of sertraline for the palliative relief of breathlessness in people with chronic breathlessness

INTRODUCTION

Breathlessness remains a highly prevalent and distressing symptom for many patients with progressive life-limiting illnesses. Evidence-based interventions for chronic breathlessness are limited, and there is an ongoing need for high-quality research into developing management strategies for optimal palliation of this complex symptom. Previous studies have suggested that selective serotonin reuptake inhibitors such as sertraline may have a role in reducing breathlessness. This paper presents the protocol for a large, adequately powered randomised study evaluating the use of sertraline for chronic breathlessness in people with progressive life-limiting illnesses.

METHODS AND ANALYSIS

A total of 240 participants with modified Medical Research Council Dyspnoea Scale breathlessness of level 2 or higher will be randomised to receive either sertraline or placebo for 28 days in this multisite, double-blind study. The dose will be titrated up every 3 days to a maximum of 100 mg daily. The primary outcome will be to compare the efficacy of sertraline with placebo in relieving the intensity of worst breathlessness as assessed by a 0-100 mm Visual Analogue Scale. A number of other outcome measures and descriptors of breathlessness as well as caregiver assessments will also be recorded to ensure adequate analysis of participant breathlessness and to allow an economic analysis to be performed. Participants will also be given the option of continuing blinded treatment until either study data collection is complete or net benefit ceases. Appropriate statistical analysis of primary and secondary outcomes will be used to describe the wealth of data obtained.

ETHICS AND DISSEMINATION

Ethics approval was obtained at all participating sites. Results of the study will be submitted for publication in peer-reviewed journals and the key findings presented at national and international conferences.

A Randomized, Double-Blind, Placebo-Controlled Trial of Low-Dose Sertraline in Young Children With Fragile X Syndrome

OBJECTIVE

Observational studies and anecdotal reports suggest that sertraline, a selective serotonin reuptake inhibitor, may improve language development in young children with fragile X syndrome (FXS).

METHODS

The authors evaluated the efficacy of 6 months of treatment with low-dose sertraline in a randomized, double-blind, placebo-controlled trial in 52 children with FXS aged 2 to 6 years.

RESULTS

Eighty-one subjects were screened for eligibility, and 57 were randomized to sertraline (27) or placebo (30). Two subjects from the sertraline arm and 3 from the placebo arm discontinued. Intent-to-treat analysis showed no difference from placebo on the primary outcomes: the Mullen Scales of Early Learning (MSEL) expressive language (EL) age equivalent and Clinical Global Impression Scale-Improvement. However, analyses of secondary measures showed significant improvements, particularly in motor and visual perceptual abilities and social participation. Sertraline was well tolerated, with no difference in side effects between sertraline and placebo groups. No serious adverse events occurred.

CONCLUSION

This randomized controlled trial of 6 months of sertraline treatment showed no primary benefit with respect to early EL development and global clinical improvement. However, in secondary exploratory analyses, there were significant improvements seen on motor and visual perceptual subtests, the cognitive T score sum on the MSEL, and on one measure of social participation on the Sensory Processing Measure-Preschool. Furthermore, post hoc analysis found significant improvement in early EL development as measured by the MSEL among children with autism spectrum disorder on sertraline. Treatment appears safe for this 6-month period in young children with FXS, but the authors do not know the long-term side effects of this treatment. These results warrant further studies of sertraline in young children with FXS using refined outcome measures as well as longer term follow-up studies to address long-term side effects of low-dose sertraline in early childhood.

Comparative efficacy and tolerability of antidepressants for major depressive disorder in children and adolescents: a network meta-analysis

BACKGROUND

Major depressive disorder is one of the most common mental disorders in children and adolescents. However, whether to use pharmacological interventions in this population and which drug should be preferred are still matters of controversy. Consequently, we aimed to compare and rank antidepressants and placebo for major depressive disorder in young people.

METHODS

We did a network meta-analysis to identify both direct and indirect evidence from relevant trials. We searched PubMed, the Cochrane Library, Web of Science, Embase, CINAHL, PsycINFO, LiLACS, regulatory agencies' websites, and international registers for published and unpublished, double-blind randomised controlled trials up to May 31, 2015, for the acute treatment of major depressive disorder in children and adolescents. We included trials of amitriptyline, citalopram, clomipramine, desipramine, duloxetine, escitalopram, fluoxetine, imipramine, mirtazapine, nefazodone, nortriptyline, paroxetine, sertraline, and venlafaxine. Trials recruiting participants with treatment-resistant depression, treatment duration of less than 4 weeks, or an overall sample size of less than ten patients were excluded. We extracted the relevant information from the published reports with a predefined data extraction sheet, and assessed the risk of bias with the Cochrane risk of bias tool. The primary outcomes were efficacy (change in depressive symptoms) and tolerability (discontinuations due to adverse events). We did pair-wise meta-analyses using the random-effects model and then did a random-effects network meta-analysis within a Bayesian framework. We assessed the quality of evidence contributing to each network estimate using the GRADE framework. This study is registered with PROSPERO, number CRD42015016023.

FINDINGS

We deemed 34 trials eligible, including 5260 participants and 14 antidepressant treatments. The quality of evidence was rated as very low in most comparisons. For efficacy, only fluoxetine was statistically significantly more effective than placebo (standardised mean difference -0·51, 95% credible interval [CrI] -0·99 to -0·03). In terms of tolerability, fluoxetine was also better than duloxetine (odds ratio [OR] 0·31, 95% CrI 0·13 to 0·95) and imipramine (0·23, 0·04 to 0·78). Patients given imipramine, venlafaxine, and duloxetine had more discontinuations due to adverse events than did those given placebo (5·49, 1·96 to 20·86; 3·19, 1·01 to 18·70; and 2·80, 1·20 to 9·42, respectively). In terms of heterogeneity, the global I(2) values were 33·21% for efficacy and 0% for tolerability.

INTERPRETATION

When considering the risk-benefit profile of antidepressants in the acute treatment of major depressive disorder, these drugs do not seem to offer a clear advantage for children and adolescents. Fluoxetine is probably the best option to consider when a pharmacological treatment is indicated.

The Impact of Sertraline Co-Administration on the Pharmacokinetics of Olanzapine: A Population Pharmacokinetic Analysis of the STOP-PD

BACKGROUND AND OBJECTIVE

Clinical evidence and expert opinion support using a combination of an antipsychotic and an antidepressant when treating major depression with psychotic features. We characterized the impact of sertraline co-administration on olanzapine clearance in psychotic depression using population pharmacokinetic methods.

METHODS

The Study of Pharmacotherapy for Psychotic Depression (STOP-PD) randomized 259 participants to olanzapine plus placebo or olanzapine plus sertraline. Olanzapine was started at 2.5-5 mg/day and sertraline at 25-50 mg/day. Doses were increased to a maximum of 20 mg/day for olanzapine and 200 mg/day for sertraline. Up to four olanzapine concentration samples were collected during the 12-week trial and 12-week continuation phase. We used NONMEM (Version VII) for population pharmacokinetic analysis, assessing effects of the covariates sex, African American origin, smoking, age, and sertraline co-administration.

RESULTS

Population pharmacokinetic analysis comprised 336 samples from 175 individuals. The structural model published by Bigos et al. was sufficient to describe the olanzapine data adequately: a one-compartment model with first-order absorption and elimination, using an additive residual error structure with the absorption rate constant fixed to 0.5. Sertraline co-administration significantly increased olanzapine apparent clearance (p < 0.005) by 25-35 % depending on the patient characteristics included. Male sex was associated with a significantly increased clearance. Age and race did not have a significant impact on clearance.

CONCLUSIONS

Contrary to expectations from the knowledge of cytochrome P450 interactions, sertraline increased olanzapine apparent clearance. Plausible explanations include patients treated with sertraline having poorer adherence to olanzapine, or the impact of sertraline inhibition of transporters resulting in increased intracellular concentrations and thus access to metabolizing enzymes.

Impact on behavioral changes due to chronic use of sertraline in Wistar albino rats

AIM

Despite having better tolerability and a wide range of clinical applications over other antidepressants, selective serotonin reuptake inhibitors (SSRIs) are also known to be associated with serious adverse effects like suicidal ideation on chronic use. The present study had explored the impact of the chronic use of sertraline, an SSRI, on the behavioral changes in Wistar albino rats.

MATERIALS AND METHODS

The study was conducted on 30 Wistar albino rats of either sex; divided into five groups. Four groups were subjected to chronic mild stress induced by using various stressors randomly scheduled in a week and continued for a period of 3 weeks. The stressed rodents were subjected to sertraline treatment for 9 weeks in different human therapeutic doses extrapolated to animal doses. Behavioral changes were monitored, assessed, and evaluated throughout the treatment phase with the help of tests such as locomotor activity test, forced swim test, tail suspension test, antianxiety test, and sucrose preference test (SPT).

RESULTS

All tests except SPT, demonstrated significant (P < 0.05) reduction in depressive-like activity in the stressed rodents by the mid-treatment phase, followed by an abrupt onset of the depressive state by the end of the treatment phase. SPT showed a significant (P < 0.05) increase in sucrose consumption throughout the treatment phase.

CONCLUSION

Behavioral changes following chronic sertraline administration conferred gradual remission of depression state on initial treatment phase, followed by a reversal of effect on chronic use.

[Efficacy and tolerability of dapoxetine in the treatment of premature ejaculation]

OBJECTIVE

To investigate the efficacy and adverse effects of dapoxetine in the treatment of premature ejaculation.

METHODS

We randomly assigned outpatients with premature ejaculation in the proportion of 2:1 to receive 30 mg dapoxetine on demand (n =78) or 50 mg sertraline qd for one month (n = 39). Follow-up was accomplished in 95 cases, 63 in the dapoxetine group and 32 in the sertraline group. We recorded the intravaginal ejaculatory latency time (IELT), clinical global impression of change (CGIC) score, and adverse reactions of the patients and compared them between the two groups.

RESULTS

IELT was significantly increased in both the dapoxetine (from [0.87 ± 0.31] to [2.84 ± 0.68] min, P < 0.05) and the sertraline group (from [0.84 ± 0.28] to [2.71 ± 0.92] min, P < 0.05) after medication. Based on the CGIC scores in premature ejaculation, the rate of excellence or effectiveness was 36.5% in the dapoxetine and 37. 5% in the sertraline group, and the rate of improvement was 63.5% in the former and 71.9% in the latter. The incidence rates of dizziness, nausea, headache, and diarrhea were slightly higher (P > 0.05) while those of fatigue, somnolence, and dry mouth significantly higher (P < 0.05) in the sertraline than in the dapoxetine group.

CONCLUSION

On-demand oral medication of dapoxetine is effective and well-tolerated for the treatment of premature ejaculation.

A randomized crossover clinical trial of sertraline for intradialytic hypotension

INTRODUCTION

Intradialytic hypotension (IDH) has been reported in 15% to 50% of hemodialysis patients and increases patients morbidity and mortality. Some small noncontrolled studies evaluated the effect of sertraline on IDH with conflicting results. This study is a randomized crossover controlled trial on the effectiveness of sertraline to reduce IDH.

MATERIALS AND METHODS

Patients on hemodialysis who suffered IDH in at least 50% of their dialysis sessions were enrolled. Each patient received either sertraline or placebo for 4 weeks and after a 4-week washout period, was switched to the other arm of the trial. All patients started sertraline at a daily dose of 50 mg that increased to 100 mg after 1 week.

RESULTS

Twelve patients completed all phases of the study. Sertraline therapy increased nadir intradialysis diastolic and systolic blood pressure by 3.8 mm Hg and 4.9 mm Hg at the end of the intervention, respectively. Sertraline therapy also significantly increased postdialysis diastolic and systolic blood pressure by 6.0 mm Hg and 8.7 mm Hg. Sertraline therapy significantly reduced the risk of hypotension episodes by 43%. The improvement of intradialysis and postdialysis diastolic and systolic blood pressure were only significant in nondiabetic patients.

CONCLUSIONS

Sertraline therapy significantly increases intradialysis and postdialysis blood pressure. These effects of sertraline can result in significant decrease in hypotension episodes during dialysis treatment and the number of interventions required to manage IDH. However, not all patients may benefit from sertraline depending on comorbidities such as diabetes mellitus.

[The Usefulness of Clonazepam as an Augmentative Treatment in a Case of Severe Childhood Onset Obsessive-Compulsive Disorder]

The goal of this study is to report on the treatment of obsessive-compulsive disorder (OCD), a chronic disabling condition that often presents during childhood and adolescence. Reports on adults using clonazepam for the treatment of OCD are more numerous than on children. Clonazepam as an augmentative treatment in OCD is still controversial. Our aim is to illustrate in a case report the efficacy of clonazepam as an augmentative treatment for severe childhood onset OCD. We report on the case of a young teenage girl with an extremely severe form of obsessive-compulsive disorder (score of 32 on the Children's Yale-Brown Obsessive Compulsive Scale), who, after a mild improvement with a combination of serotonin recapture inhibitors and second generation antipsychotics at high doses, has responded to clonazepam (3mg/day) augmentation of sertraline (200mg/day) and olanzapine (15mg/day). Clonazepam was effective not only in reducing anxiety symptoms, but also in lowering compulsions and obsessions frequency within 6 weeks with a drop in the Children's Yale-Brown Obsessive Compulsive Scale of 16 points. It may be asserted that clonazepam could be useful in the initial stage for severe OCD in young patients.

Intraperitoneal sertraline and fluvoxamine increase contextual fear conditioning but are without effect on overshadowing between cues

Treatment with selective serotonin reuptake inhibitors (SSRIs) can reduce contextual conditioning. Since contexts comprise a variety of potentially competing cues, impaired overshadowing may provide an account of such effects. The present study therefore compared the effects of two SSRIs on overshadowing and contextual conditioning, testing suppression of an ongoing behavioral response (licking) by cues previously paired with foot shock. Conditioning to a 5 s light stimulus was reduced when it was presented in compound with a 5 s noise, thus overshadowing was demonstrated. In two experiments, this overshadowing was unaffected by treatment with either sertraline or fluvoxamine. However, unconditioned suppression to the noise (tested in a control group previously conditioned to the light alone) was reduced after sertraline (10 mg/kg, i.p.). The successful demonstration of overshadowing required the use of a second conditioning session or an additional conditioning trial within the same conditioning session. Neither weak nor strong overshadowing (of the light by the tone) was affected by any drug treatment. Moreover, counter to prediction, conditioning to contextual cues was increased rather than impaired by treatment with sertraline (10 mg/kg, i.p.) and fluvoxamine (30 mg/kg, i.p.).

•

Setraline (10 mg/kg) increased latency to drink in the conditioning context.

•

Fluvoxamine (30 mg/kg) reduced licking in the conditioning context.

•

Discrete cue conditioning to an overshadowed light cue was unaffected.

•

Setraline (10 mg/kg) reduced unconditioned suppression to the overshadowing noise.

Sertraline reduces IL-1β and TNF-α mRNA expression and overcomes their rise induced by seizures in the rat hippocampus

We recently discovered that the antidepressant sertraline is an effective inhibitor of hippocampus presynaptic Na⁺ channel permeability invitro and of tonic-clonic seizures in animals invivo. Several studies indicate that the pro-inflammatory cytokines in the central nervous system are increased in epilepsy and depression. On the other hand inhibition of Na⁺ channels has been shown to decrease pro-inflammatory cytokines in microglia. Therefore, the possibility that sertraline could overcome the rise in pro-inflammatory cytokine expression induced by seizures has been investigated. For this purpose, IL-1β and TNF-α mRNA expression was determined by RT-PCR in the hippocampus of rats administered once, or for seven consecutive days with sertraline at a low dose (0.75 mg/kg). The effect of sertraline at doses within the range of 0.75 to 25 mg/kg on the increase in IL-1β and TNF-α mRNA expression accompanying generalized tonic-clonic seizures, and increase in the pro-inflammatory cytokines expression induced by lipopolysaccharide was also investigated. We found that under basal conditions, a single 0.75 mg/kg sertraline dose decreased IL-1β mRNA expression, and also TNF-α expression after repeated doses. The increase in IL-1β and TNF-α expression induced by the convulsive agents and by the inoculation of lipopolysaccharide in the hippocampus was markedly reduced by sertraline also. Present results indicate that a reduction of brain inflammatory processes may contribute to the anti-seizure sertraline action, and that sertraline can be safely and successfully used at low doses to treat depression in epileptic patients.

Modulating cancer multidrug resistance by sertraline in combination with a nanomedicine

Inherent and acquired multiple drug resistance (MDR) to chemotherapeutic drugs is a major obstacle in cancer treatment. The ATP Binding Cassettes (ABC) transporter super family that act as extrusion pumps such as P-glycoprotein and multidrug-resistance-associated-proteins have prominent roles in cancer MDR. One of the most efficient strategies to modulate this active drug efflux from the cells is to physically block the pump proteins and thus change the balance between drug influx and efflux toward an accumulation of drug inside the cell, which eventually cumulates into cell death. MDR modulators (also known as chemosensitizers) were found among drugs approved for non-cancer indications. Yet, toxicity, adverse effects, and poor solubility at doses required for MDR reversal prevent their clinical application. Previous reports have shown that drugs belonging to the selective serotonin reuptake inhibitors (SSRI) family, which are clinically used as antidepressants, can act as effective chemosensitizers both in vitro and in vivo in tumor bearing mouse models. Here, we set out to explore whether sertraline (Zoloft®), a molecule belonging to the SSRI family, can be used as an MDR modulator. Combining sertraline with another FDA approved drug, Doxil® (pegylated liposomal doxorubicin), is expected to enhance the effect of chemotherapy while potentially reducing adverse effects. Our findings reveal that sertraline acts as a pump modulator in cellular models of MDR. In addition, in an aggressive and highly resistant human ovarian xenograft mouse model the use of sertraline in combination with Doxil® generated substantial reduction in tumor progression, with extension of the median survival of tumor-bearing mice. Taken together, our results show that sertraline could act as a clinically relevant cancer MDR inhibitor. Moreover, combining two FDA approved drugs, DOXIL®, which favor the influx of chemotherapy inside the malignant cell with sertraline, which blocks the extrusion pumps, could readily be available for clinical translation in the battle against resistant tumors.

Using semantic predications to uncover drug-drug interactions in clinical data

In this study we report on potential drug-drug interactions between drugs occurring in patient clinical data. Results are based on relationships in SemMedDB, a database of structured knowledge extracted from all MEDLINE citations (titles and abstracts) using SemRep. The core of our methodology is to construct two potential drug-drug interaction schemas, based on relationships extracted from SemMedDB. In the first schema, Drug1 and Drug2 interact through Drug1's effect on some gene, which in turn affects Drug2. In the second, Drug1 affects Gene1, while Drug2 affects Gene2. Gene1 and Gene2, together, then have an effect on some biological function. After checking each drug pair from the medication lists of each of 22 patients, we found 19 known and 62 unknown drug-drug interactions using both schemas. For example, our results suggest that the interaction of Lisinopril, an ACE inhibitor commonly prescribed for hypertension, and the antidepressant sertraline can potentially increase the likelihood and possibly the severity of psoriasis. We also assessed the relationships extracted by SemRep from a linguistic perspective and found that the precision of SemRep was 0.58 for 300 randomly selected sentences from MEDLINE. Our study demonstrates that the use of structured knowledge in the form of relationships from the biomedical literature can support the discovery of potential drug-drug interactions occurring in patient clinical data. Moreover, SemMedDB provides a good knowledge resource for expanding the range of drugs, genes, and biological functions considered as elements in various drug-drug interaction pathways.

Effects of antidepressants and soybean association in depressive menopausal women

Depression in menopausal women has been widely described for many years ago and is related to hormonal decrease, mainly estrogens. The use of soy has been proposed as a possible coadjutant alternative to treat menopausal depressive disorder. In the present pilot clinical trial the effect of soybean, antidepressants and the association of soybean with antidepressants was studied in 40 depressive menopausal women for three months. Patients were divided in four groups of 10 women: fluoxetine (10 mg), soybean (100 mg), sertraline (50 mg), and sertraline (50 mg) plus soybean (100 mg). The Hamilton and Zung Depression Scales were used to measure the treatment effects. Values at the beginning and at the end of the study were compared. In all cases a significant difference was observed when the treated groups were compared vs. their untreated situation in both scales (p < 0.001). When a comparison between pre- minus post-treatment Zung scale scores was done, the effect induced by the association of sertraline and soybean was significantly higher than the other groups (p < 0.05). These effects were also seen using the Hamilton scale scores, showing significant differences between the association vs. soybean (p < 0.05) and setraline (p < 0.05) groups, but not vs. fluoxetine group. We conclude that soybean has an antidepressant effect per se, and the association of soybean and antidepressants increases their effects.

Off-patent generic medicines vs. off-patent brand medicines for six reference drugs: a retrospective claims data study from five local healthcare units in the Lombardy Region of Italy

The scientific documentation supporting the potential clinical and economic benefits of a growing use of off-patent generic drugs in clinical practice seems to be limited in Italy as yet.

METHODS

We compared differences in outcomes between off-patent generic drugs and off-patent brand drugs in real clinical practice. The outcomes were: persistence and compliance with therapy, mortality, and other health resources consumption (hospitalizations, specialist examinations, other drugs) and total costs. Retrospective analysis was carried out by using the administrative databases of five Local Healthcare Units (ASLs - Aziende Sanitarie Locali) in the Lombardy Region of Italy. Data from the five ASLs were aggregated through a meta-analysis, which produced an estimate indicator of the mean or percentage difference between the two groups (branded vs. generic) and their respective significance tests. The therapeutic areas and studied drugs were: diabetes: metformin - A10BA02; hypertension: amlodipine - C08CA01; dyslipidemia: simvastatin - C10AA01; psychiatry: sertraline - N06AB06; cardiology: propafenone - C01BC03; osteoporosis: alendronate - M05BA04.

RESULTS

The 5 Local Healthcare Units (ASL) represent a population of 3,847,004 inhabitants. The selected sample included 347,073 patients, or 9.02% of the total ASL population; 67% of the patients were treated with off-patent brand drugs. The average age was 68 years, with no difference between the two groups. After 34 months of observation, compliance and persistence were in favor to generic drugs in all therapeutic areas and statistically significant in the metformin, amlodipine, simvastatin, and sertraline groups. The clinical outcomes (hospitalizations, mortality, and other health costs) show no statistically significant differences between off-patent generic vs. off-patent brand medicines.

CONCLUSIONS

Off-patent generic drugs appear to be a therapy option of choice in Italy as well, based on clinical outcomes and economic consequences, both for the National Health Service and patients, considering that the price difference between brand and generic drugs is completely charged on patients.

Randomized, placebo-controlled trial of cognitive-behavioral therapy alone or combined with sertraline in the treatment of pediatric obsessive-compulsive disorder

BACKGROUND

To examine the efficacy of sequential sertraline and cognitive-behavioral therapy (CBT) treatment relative to CBT with pill placebo over 18 weeks in children and adolescents with obsessive-compulsive disorder (OCD).

METHODS

Forty-seven children and adolescents with OCD (Range = 7-17 years) were randomized to 18-weeks of treatment in one of three arms: 1) sertraline at standard dosing + CBT (RegSert + CBT); 2) sertraline titrated slowly but achieving at least 8 weeks on the maximally tolerated daily dose + CBT (SloSert + CBT); or 3) pill placebo + CBT (PBO + CBT). Assessments were conducted at screening, baseline, weeks 1-9, 13, and 17, and post-treatment. Raters and clinicians were blinded to sertraline (but not CBT) randomization status. Primary outcomes included the Children's Yale-Brown Obsessive-Compulsive Scale, and response and remission status. Secondary outcomes included the Child Obsessive Compulsive Impact Scale-Parent/Child, Children's Depression Rating Scale-Revised, Multidimensional Anxiety Scale for Children, and Clinical-Global Impressions-Severity.

RESULTS

All groups exhibited large within-group effects across outcomes. There was no group by time interaction across all outcomes suggesting that group changes over time were comparable.

CONCLUSIONS

Among youth with OCD, there was no evidence that sequentially provided sertraline with CBT differed from those receiving placebo with CBT.

A gender analysis of the study of pharmacotherapy of psychotic depression (STOP-PD): gender and age as predictors of response and treatment-associated changes in body mass index and metabolic measures

BACKGROUND

Gender differences exist in psychiatric disorders; however, gender has not been well studied in psychotic depression. This analysis of the largest clinical trial in psychotic depression examined the effects of age and gender on clinical characteristics and predictors of treatment outcome and treatment-associated changes in body mass index (BMI) and metabolic measures.

METHOD

Secondary analyses were performed on data from 259 subjects with major depressive disorder with psychotic features (DSM-IV-TR) aged 18-93 years in the double-blind randomized controlled trial of olanzapine plus sertraline versus olanzapine plus placebo for psychotic depression (Study of Pharmacotherapy of Psychotic Depression). Sociodemographic factors, clinical characteristics, treatment outcome, and treatment-associated changes in BMI and metabolic measures were analyzed by gender and age. Subjects were enrolled from December 2002 to June 2007.

RESULTS

Female gender was associated with divorced (χ(2)(1) = 5.3, P = .03) or widowed (χ(2)(1) = 8.1, P ≤ .01) marital status. Comorbid anxiety disorders were more common in women than in men (χ(2)(1) = 4.9, P = .03). Hallucinations (χ(2)(1) = 7.8, P = .005) and delusions with disorganization (t(257) = -2.10, P = .04) were significantly associated with female gender, as were higher cholesterol measures (χ(2)(1) = 7.15, P = .008). There were no significant interactions between treatment and gender in terms of change in BMI. Gender was not associated with treatment response.

DISCUSSION

This study is the first analysis of gender and age as predictors of treatment outcome and treatment-associated changes in BMI and metabolic adverse effects in psychotic depression. Gender differences exist in patients with psychotic depression, most notably with regard to the presence of hallucinations. Female gender was associated with metabolic measures. Future studies with larger sample sizes may detect small gender differences in treatment outcome and treatment-associated changes in BMI and metabolic measures in psychotic depression.

The therapeutic relationship in cognitive-behavioral therapy and pharmacotherapy for anxious youth

OBJECTIVE

We examined the therapeutic relationship with cognitive-behavioral therapists and with pharmacotherapists for youth from the Child/Adolescent Anxiety Multimodal Study (Walkup et al., 2008). The therapeutic relationship was examined in relation to treatment outcomes.

METHOD

Participants were 488 youth (ages 7-17 years; 50% male) randomized to cognitive-behavioral therapy (CBT; Coping Cat), pharmacotherapy (sertraline), their combination, or placebo pill. Participants met criteria for generalized anxiety disorder, social phobia, and/or separation anxiety disorder according to the Diagnostic and Statistical Manual of Mental Disorders (4th ed.; American Psychiatric Association, 1994). The therapeutic relationship was assessed by youth report at Weeks 6 and 12 of treatment using the Child's Perception of Therapeutic Relationship scale (Kendall et al., 1997). Outcome measures (Pediatric Anxiety Rating Scale; Research Units on Pediatric Psychopharmacology Anxiety Study Group, 2002; and Clinical Global Impressions Scales; Guy, 1976) were completed by independent evaluators blind to condition.

RESULTS

For youth who received CBT only, a stronger therapeutic relationship predicted positive treatment outcome. In contrast, the therapeutic relationship did not predict outcome for youth receiving sertraline, combined treatment, or placebo.

CONCLUSION

A therapeutic relationship may be important for anxious youth who receive CBT alone.

Sertraline and mirtazapine as geriatric antidepressants

BACKGROUND

Depression within the geriatric patient population is an important issue as it is associated with increased mortality. Such depression may have a different aetiology to that in younger patients and be associated with comorbid chronic physical health problems or cognitive impairment. However, there is no specific UK guideline for the treatment of depression within elderly patients. The first-line pharmacological treatment recommended by the National Institute for Health and Care Excellence (NICE) is to use a serotonin-selective reuptake inhibitor (SSRI). Unfortunately these can have significant side-effects in the elderly such as hyponatraemia. Sertraline is one such SSRI commonly used in the geriatric population. Mirtazapine, a noradrenergic and specific serotonergic antidepressant (NaSSa) is seeing increasing usage as an alternative agent. Here we evaluate the role of using the NaSSA in place of the SSRI and how such drugs may be cross-titrated.

METHODS

PubMed and an internet search engine were used to identify relevant studies and information sources.

CONCLUSIONS

Limited evidence suggests that for certain elderly patients, mirtazapine may be preferable to sertraline for treatment of depression. It may also be more cost-effective in patients who have dementia. The choice is highly dependent upon individual co-morbidities and subsequent polypharmacy. If required, sertaline can be cross-titrated to mirtazapine.

Agomelatine and sertraline for the treatment of depression in type 2 diabetes mellitus

OBJECTIVE

The present study compared the efficacy of agomelatine and sertraline in the treatment of symptoms of depression/anxiety, diabetes self-care and metabolic control in a sample of depressed patients with non-optimally controlled type 2 diabetes mellitus (DM).

METHOD

This was an observational open label study of 40 depressed patients with DM who were randomly assigned to receive either agomelatine or sertraline, and were assessed over a 4-month period for depression, anxiety, self-care, fasting plasma glucose, haemoglobin A1c and body weight.

RESULTS

Lower anxiety and depression scores as well as higher self-care scores were measured in the agomelatine group compared with the sertraline group after 4 months of treatment. Although the main effects of treatment on final body weight and fasting plasma glucose were not significant, significantly lower final haemoglobin A1c levels were measured in the agomelatine group compared with the sertraline group. Both antidepressants were well tolerated and none of the patients dropped-out of the study.

CONCLUSION

The main finding of the present small pilot study was that agomelatine may be a promising agent in the treatment of symptoms of depression and anxiety as well as in the improvement of health-related behaviours, in depressed patients with type 2 DM possibly offering some advantages over sertraline. However, the lack of a placebo control group limits the generalisability of the findings and warrants further studies.

Capgras syndrome presenting in an adolescent girl in the Caribbean

The case of a 16-year old Jamaican girl who presented to the psychiatric service of a general hospital with features of Capgras syndrome is presented. Her history, treatment, progress and relevant psychodynamic and neurocognitive issues are explored. This is the first known published case of an adolescent with Capgras syndrome from the Caribbean. The case highlights that the syndrome may occur in different cultural contexts and that clinicians should be sensitive to its existence in order to avert under-diagnosis or misdiagnosis.

Newer generation antidepressants for depressive disorders in children and adolescents

BACKGROUND

Depressive disorders are common in young people and are associated with significant negative impacts. Newer generation antidepressants, particularly selective serotonin reuptake inhibitors (SSRIs), are often used, however evidence of their effectiveness in children and adolescents is not clear. Furthermore, there have been warnings against their use in this population due to concerns about increased risk of suicidal ideation and behaviour.

OBJECTIVES

To determine the efficacy and adverse outcomes, including definitive suicidal behaviour and suicidal ideation, of newer generation antidepressants compared with placebo in the treatment of depressive disorders in children and adolescents.

SEARCH METHODS

For this update of the review, we searched the Cochrane Depression, Anxiety and Neurosis Review Group's Specialised Register (CCDANCTR) to October 2011. The CCDANCTR includes relevant randomised controlled trials from the following bibliographic databases: CENTRAL (the Cochrane Central Register of Controlled Trials) (all years), EMBASE (1974 -), MEDLINE (1950 -) and PsycINFO (1967 -). We searched clinical trial registries and pharmaceutical company websites. We checked reference lists of included trials and other reviews, and sent letters to key researchers and the pharmaceutical companies of included trials from January to August 2011.

SELECTION CRITERIA

Published and unpublished randomised controlled trials (RCTs), cross-over trials and cluster trials comparing a newer generation antidepressant with a placebo in children and adolescents aged 6 to 18 years old and diagnosed with a depressive disorder were eligible for inclusion. In this update, we amended the selection criteria to include newer generation antidepressants rather than SSRIs only.

DATA COLLECTION AND ANALYSIS

Two or three review authors selected the trials, assessed their quality, and extracted trial and outcome data. We used a random-effects meta-analysis. We used risk ratio (RR) to summarise dichotomous outcomes and mean difference (MD) to summarise continuous measures.

MAIN RESULTS

Nineteen trials of a range of newer antidepressants compared with placebo, containing 3335 participants, were included. The trials excluded young people at high risk of suicide and many co-morbid conditions and the participants are likely to be less unwell than those seen in clinical practice. We judged none of these trials to be at low risk of bias, with limited information about many aspects of risk of bias, high drop out rates and issues regarding measurement instruments and the clinical usefulness of outcomes, which were often variously defined across trials. Overall, there was evidence that those treated with an antidepressant had lower depression severity scores and higher rates of response/remission than those on placebo. However, the size of these effects was small with a reduction in depression symptoms of 3.51 on a scale from 17 to 113 (14 trials; N = 2490; MD -3.51; 95% confidence interval (CI) -4.55 to -2.47). Remission rates increased from 380 per 1000 to 448 per 1000 for those treated with an antidepressant. There was evidence of an increased risk (58%) of suicide-related outcome for those on antidepressants compared with a placebo (17 trials; N = 3229; RR 1.58; 95% CI 1.02 to 2.45). This equates to an increased risk in a group with a median baseline risk from 25 in 1000 to 40 in 1000. Where rates of adverse events were reported, this was higher for those prescribed an antidepressant. There was no evidence that the magnitude of intervention effects (compared with placebo) were modified by individual drug class.

AUTHORS' CONCLUSIONS

Caution is required in interpreting the results given the methodological limitations of the included trials in terms of internal and external validity. Further, the size and clinical meaningfulness of statistically significant results are uncertain. However, given the risks of untreated depression in terms of completed suicide and impacts on functioning, if a decision to use medication is agreed, then fluoxetine might be the medication of first choice given guideline recommendations. Clinicians need to keep in mind that there is evidence of an increased risk of suicide-related outcomes in those treated with antidepressant medications.

Bupropion versus sertraline in the treatment of depressive patients with binge eating disorder: retrospective cohort study

This study sought to compare Bupropion versus Sertraline in the treatment of depressed patients with Binge Eating Disorder (BED) prescribed off-label. Medical records of outpatients with diagnosis of BED and Depression (DSM-IV-TR criteria) were selected: 15 patients were treated with bupropion 150 mg/per day, and 15 with sertraline 200 mg/per day. During the screening and control visits (2°-6°-14°-24° week), the selected patients were first weighed and then evaluated using the following questionnaires: Binge Eating Disorder-Clinical Interview (BEDCI), Beck Depression Inventory (BDI), State-Trait Anxiety Inventory X (STAI-X) and Arizona Sexual Experience Scale (ASEX). Both drugs reduced anxious-depressive symptoms and binge frequency: Bupropion showed a better effectiveness in reducing weight and improving sexual performances; weight loss related to it was proportional to the body mass index. Bupropion may be associated with more weight loss in BED, depressed patients than sertraline.

Switching to sertraline or venlafaxine after failure of SSRIs treatment in major depressive disorder: an economic evaluation of the STAR*D trial

BACKGROUND

Switching to another antidepressant is one of the alternative treatment strategies employed in major depressive disorder (MDD) patients who have no remission despite an adequate trial of an antidepressant. The aim of the present study was to present an economic evaluation of sertraline compared with venlafaxine after unsuccessful treatment for depression with citalopram.

MATERIAL AND METHOD

An economic model was constructed in line with the design of the sequenced treatment alternatives to relieve depression (STAR*D) study. MDD patients who did not have a remission with or who had an intolerance to citalopram were randomly assigned to be switched to either sertraline or venlafaxine. Patients who had no remission at the end of the switching treatment phase still continued the antidepressants and received an adjunctive treatment with aripiprazole. The event probabilities were used to derive the transitional probabilities use in the model. The primary model outcome was remission of symptoms and the secondary outcome was quality-adjusted life-years (QALYs). Incremental cost-effectiveness ratios (ICEs) were estimated for the costs per unit of effectiveness. Sensitivity analyses were done to assess the effects of model assumptions.

RESULTS

The total direct costs per remission were 27,830 Baht for sertraline and 30,147 Baht for venlafaxine. Sertraline had lower total costs per QALY than venlafaxine (34,788 Baht vs. 37,683 Baht). The more cost-effectiveness of sertraline resulted in 7.68% of cost saving. The incremental cost of venlafaxine compared with sertraline was 2,316 Baht per remission gained and 2895 Baht per QALY gained. By varying the remission rate of venlafaxine from 20% to 40%, the sensitivity analysis results in a decrease in total costs of venlafaxine from 31,926 Baht to 24,808 Baht. In addition, incremental cost per remission gained changed from 4096 Baht in favour of sertraline to 3023 Baht in favour of venlafaxine. Similarly, incremental cost per QALY gained changedfrom in favour of sertraline to in favour of venlafaxine.

CONCLUSION

Based on the STAR*D trial, the results of the economic study indicate that a switch to sertraline is a cost-effectiveness treatment option compared with a switch to venlafaxine in MDD patients who have no remission or cannot tolerate citalopram.

[Use of pregabalin and sertraline in complex treatment of patients with partial epilepsy comorbid with depressive and anxiety disorders]

Objective of this study was evaluation therapeutic efficacy and adverse effects of the combined treatment in patients with partial epilepsy comorbid with depressive and anxiety disorders. Patients were treated with antiepileptic drugs (AED) as monotherapy before and during the investigation. Patients of group 1 (42 cases) were administrated sertraline (SER) 100 mg per day in combination with pregabalin (PGB) 300 mg per day in addition to basic AED. Patients of group 2 (41 cases) were treated with SER 100 mg per day in addition to basic AED. The duration of the investigation has made 6 months. In this study several characteristics had been evaluated in each group: seizure frequency, severity of depressive and anxiety disorders, adverse effects of the drugs administrated. Moreover, dynamics of types of attitude to the disease were investigated under the drugs administration in each group. SER and PGB demonstrated high efficacy and safety in treatment partial epilepsy comorbid with depressive and anxiety disorders. PGB must be recommended in adjunctive therapy of anxiety disorders in patients with partial epilepsy.

[The dynamics of anxious depression under the treatment with antidepressants with different mechanisms of action]

Peculiarities of the dynamics of anxious depression under the treatment with selective serotonergic antidepressants with different mechanisms of action on the serotonin reuptake were investigated. It was examined 61 patients with anxious depression (ICD-10 F32.1, F33.1, F34.1) treated with zoloft (sertraline) or coaxil (tianeptine) as a monotherapy. The following methods were used: clinical-psychopathological, psychometric (Hamilton Rating Scales for Depression and Anxiety, the Sheehan Patient-Related Anxiety Scale) and statistical analysis. The comparative investigation has shown that both zoloft and coaxil are practically equally effective in the treatment of anxious depression with some peculiarities in the dynamics of clinical parameters.

Serotonin Reuptake Inhibitors: Bioequivalence of Sertraline Capsules

The study was designed to evaluate the bioavailability of two sertraline (CAS 79617-96-2) formulations. A bioequivalence study was carried out in 24 healthy male volunteers, who were administered 50 mg capsules of the test formulation (Seralin) and the originator product (reference) as a single dose. The trial was performed according to an open, randomized, cross-over design with a washout period of 14-20 days in one study center. Blood samples were taken up to 96 h post dose, the plasma was separated and the concentrations of sertraline were determined by HPLC-MS-MS. The mean Cmax were 9.01 +/- 2.26 ng/mL and 8.24 +/- 2.14 ng/mL, while the mean AUC0-t were 259.09 +/- 105.36 ng x h/mL and 234.36 +/- 95.18 ng x h/mL for the test and reference formulations, respectively. The mean AUC0-inf were 292.66 +/- 128.09 ng x h/mL (test) and 267.23 +/- 116.40 ng x h/ mL (reference). The mean tmax was 5.88 +/- 1.03 h for the test capsules and 6.17 +/- 1.66 h for the reference formula. The mean t1/2el was 26.49 +/- 6.45 h for the test formulation and 26.23 +/- 6.64 h for the reference formulation. Mean MRT values for the test and reference formulations were 28.14 +/- 5.37 h and 27.81 +/- 5.13 h, respectively. No significant differences of pharmacokinetic parameters between the two studied formulations were found. The 90% confidence interval for the primary target parameters, intra-individual ratios of AUC0-t and Cmax of sertraline were between 1.03 and 1.19 (AUC0-t) as well as between 1.02 and 1.17 (Cmax) and thus within the acceptance ranges for bioequivalence trials. Concerning the secondary parameter tmax the 90% confidence interval for the intra-individual differences was between -1.00 and 0.50 h. In the light of the present study it can be concluded that sertraline test capsules are bioequivalent to the reference formulation.

Comparative Bioavailability/Bioequivalence of Two Different Sertraline Formulations

An open-label, randomised, crossover single dose study, using 2 periods x 2 sequences, with a minimum washout period of 4 weeks, was conducted in order to assess the comparative bioavailability of two formulations of sertraline hydrochloride (CAS 79617-96-2) 100 mg tablets. Plasma samples were obtained at intake (baseline) and at +1 h, +2 h, +3 h, +4 h, +5 h, +6 h, +7 h, +8 h, +9 h, +12 h, +24 h, +48 h, +72 h and +96 h post administration. Sertraline plasma concentrations were determined by high pressure liquid chromatography with tandem mass detection (HPLC-MS/MS) and the lower limit of quantification was set at 100.15 pg/mL. Pharmacokinetic parameters used for bioequivalence assessment (AUClast, AUCinf and Cmax) were determined by non-compartmental analysis. Classical 90 % confidence intervals (90CI) were calculated for the overall sample, and for males and females separately, and gender effects were investigated using an appropriate model. The results showed that overall classical 90CI were 84.55-100.32 % for Cmax 86.96-98.68 % for AUClast, and 86.79-98.93 for AUCinf, that is, they were all within the predefined ranges for bioequivalence acceptance. Separate gender analysis showed very similar results for males and females when analysed independently, and no gender effects were detected in bioequivalence analysis (p > 0.05). It may be therefore concluded that the evaluated formulations are bioequivalent in terms of rate and extent of absorption.

[Vascular depressions]

The notion of vascular depression (VD) includes depressive disorders resulting from organic cerebral lesions of vascular genesis. Two types of VD are distinguished: post-stroke VD (PSD) and VD proper (SDP). VD develops in case of clinically manifest (neurologic) lesions in cerebral vessels that simultaneously act as psychogenic (nosogenic) factors. SDP is associated with clinically latent vascular disorders ("silent" infarctions and white matter ischemia). VD is characterized by multiple phenomenological convergence of vascular signs and symptoms inherent in both PSD and SDP. Whatever the type of VDs, they are associated with frequent cognitive problems with a variety of dynamic patterns, viz. reversible, relatively stable, and progressing.

Sertraline treatment of children and adolescents with posttraumatic stress disorder: a double-blind, placebo-controlled trial

OBJECTIVE

The aim of this study was to evaluate the safety and efficacy of sertraline in children and adolescents who met Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV) criteria for posttraumatic stress disorder (PTSD).

METHOD

Children and adolescents (6-17 years old) meeting DSM-IV criteria for PTSD were randomized to 10 weeks of double-blind treatment with sertraline (50-200  mg/day) or placebo. The primary efficacy measure was the University of California, Los Angeles Post-Traumatic Stress Disorder Index for DSM-IV (UCLA PTSD-I).

RESULTS

A total of 131 patients met entry criteria and were randomized to sertraline (n = 67; female, 59.7%; mean age, 10.8; mean UCLA PTSD-I score, 43.8 ± 8.5) or placebo (n = 62; female, 61.3%; mean age, 11.2; mean UCLA PTSD-I score, 42.1 ± 8.8). There was no difference between sertraline and placebo in least squares (LS) mean change in the UCLA PTSD-I score, either on a completer analysis (-20.4 ± 2.1 vs. -22.8 ± 2.1; p = 0.373) or on an last observation carried forward (LOCF) end point analysis (-17.7 ± 1.9 vs. -20.8 ± 2.1; p = 0.201). Attrition was higher on sertraline (29.9%) compared to placebo (17.7%). Discontinuation due to adverse events occurred in a 7.5% treated with sertraline and 3.2% treated with placebo.

CONCLUSIONS

Sertraline was a generally safe treatment in children and adolescents with PTSD, but did not demonstrate efficacy when compared to placebo during 10 weeks of treatment. ClinicalTrials.gov Identifier: NCT00150306.

Assessment of the toxicological interaction of sertraline with cholinesterase inhibiting insecticides in aquatic insects using the black fly, Simulium vittatum IS-7

Sertraline is a selective serotonin reuptake inhibitor (SSRI) prescribed as an antidepressant. Although SSRIs are known to block serotonin reuptake sites on cell membranes, they also have been shown to inhibit acetylcholinesterase (AChE) activity. Thus, the interaction of these chemicals with other AChE inhibitors, namely, organophosphate and carbamate insecticides, is of interest. In addition, these insecticides have been shown to interact with serotonergic neuronal pathways creating questions as to how these chemicals might interact. In this study, the interactive effect of sertraline (SSRI) in binary combinations with carbaryl (carbamate insecticide) and diazinon (organophosphate insecticide) was assessed using a 48-h acute toxicity test with black fly larvae, Simulium vittatum IS-7. Results showed that observed mortality was bracketed by the independent action model and concentration addition model with the independent action model slightly underestimating mortality and the concentration addition model slightly overestimating mortality. Varying the concentration of the chemicals in the mixture did not indicate that sertraline was interacting with the insecticides to make them more toxic or vice versa. These results indicate that sertraline and the insecticides are likely eliciting toxicity at separate neuronal pathways since no interaction was observed.

Antidepressant induced apathy responsive to dose reduction

Apathy has a significant negative impact on the quality of life. It can be a part of other axis I and axis III disorders such as depression. It has also been reported as a treatment emergent side effect of SSRI drugs. A 48 year old male with diagnosis of personality change due to medical condition and depressive symptoms was started on Sertraline. Although his depressive symptoms, impulse control and his irritability improved significantly he became quite apathetic. This responded positively to a reduction in the dose of sertraline. Since apathy can be a residual symptom of depression it may be a valid consideration to increase the dose of the SSRI. However if apathy was not a significant part of depressive syndrome prior to SSRI treatment then antidepressant treatment emergent apathy needs to be considered and one option is to reduce the dose of the SSRI. Other options appear to be addition of other pharmacological agents such as stimulants, dopamine agonists, acetylcholinesterase inhibitors and NMDA antagonists.

Omega-3 augmentation of sertraline in treatment of depression in patients with coronary heart disease: a randomized controlled trial

CONTEXT

Studies of depressed psychiatric patients have shown that antidepressant efficacy can be increased by augmentation with omega-3 fatty acids.

OBJECTIVE

To determine whether omega-3 improves the response to sertraline in patients with major depression and coronary heart disease (CHD).

DESIGN, SETTING, AND PARTICIPANTS

Randomized controlled trial. Between May 2005 and December 2008, 122 patients in St Louis, Missouri, with major depression and CHD were randomized.

INTERVENTIONS

After a 2-week run-in period, all patients were given 50 mg/d of sertraline and randomized in double-blind fashion to receive 2 g/d of omega-3 acid ethyl esters (930 mg of eicosapentaenoic acid [EPA] and 750 mg of docosahexaenoic acid [DHA]) (n=62) or to corn oil placebo capsules (n=60) for 10 weeks.

MAIN OUTCOME MEASURES

Scores on the Beck Depression Inventory (BDI-II) and the Hamilton Rating Scale for Depression (HAM-D).

RESULTS

Adherence to the medication regimen was 97% or more in both groups for both medications. There were no differences in weekly BDI-II scores (treatment x time interaction = 0.02; 95% confidence interval [CI], -0.33 to 0.36; t(112) = 0.11; P = .91), pre-post BDI-II scores (placebo, 14.8 vs omega-3, 16.1; 95% difference-in-means CI, -4.5 to 2.0; t(116) = -0.77; P = .44), or HAM-D scores (placebo, 9.4 vs omega-3, 9.3; 95% difference-in-means CI, -2.2 to 2.4; t(115) = 0.12; P = .90). The groups did not differ on predefined indicators of depression remission (BDI-II < or = 8: placebo, 27.4% vs omega-3, 28.3%; odds ratio [OR], 0.96; 95% CI, 0.43-2.15; t(113) = -0.11; P = .91) or response (> 50% reduction in BDI-II from baseline: placebo, 49.0% vs omega-3, 47.7%; OR, 1.06; 95% CI, 0.51-2.19; t(112) = 0.15; P = .88).

CONCLUSIONS

Treatment of patients with CHD and major depression with sertraline and omega-3 fatty acids did not result in superior depression outcomes at 10 weeks, compared with sertraline and placebo. Whether higher doses of omega-3 or sertraline, a different ratio of EPA to DHA, longer treatment, or omega-3 monotherapy can improve depression in patients with CHD remains to be determined.

A randomized controlled trial of sertraline for the treatment of depression in persons with traumatic brain injury

OBJECTIVE

To examine the efficacy of sertraline in the treatment of depression after traumatic brain injury (TBI).

DESIGN

Double-blind, randomized controlled trial.

SETTING

Research center at a major urban medical center.

PARTICIPANTS

Subjects were a referred and volunteer sample of 52 participants with TBI, a diagnosis of major depression disorder (MDD), and a score on the Hamilton Rating Scale for Depression (HAM-D) of 18 or greater. The majority of the sample was male (58%), had less than 14 years of education (73%), had incomes below $20,000 (82%), and were from minority backgrounds (75%). Approximately one third of the sample had mild brain injuries, and two thirds had moderate to severe brain injuries. The mean age was 47+/-11, and the mean time since injury was 17+/-14 years. One participant withdrew from the study because of side effects.

INTERVENTION

Daily oral sertraline in doses starting at 25mg and increasing to therapeutic levels (up to 200mg) or placebo for 10 weeks.

MAIN OUTCOME MEASURES

The HAM-D, the Beck Anxiety Inventory, and the Life-3 quality of life (QOL).

RESULTS

No statistically significant differences were found at baseline between drug and placebo groups on baseline measures of depression (24.8+/-7.3 vs 27.7+/-7.0), anxiety (16.4+/-12.3 vs 24.0+/-14.9), or QOL (2.96+/-1.0 vs 2.9+/-0.9). The income level of those receiving placebo was significantly lower than those participants receiving medication. Analyses of covariance revealed significant changes from preintervention to posttreatment for all 3 outcome measures (P<.001) but no group effects. Random-effects modeling did not find any significant difference in patterns of scores of the outcome measures between the placebo and medication groups.

CONCLUSIONS

Both groups showed improvements in mood, anxiety, and QOL, with 59% of the experimental group and 32% of the placebo group responding to the treatment, defined as a reduction of a person's HAM-D score by 50%.
