The risk of acute infections in new users of antidepressants: An observational cohort study.

BACKGROUND: Preclinical studies suggested that drugs that functionally inhibit acid sphingomyelinase (FIASMA)may enhance immune cell longevity and potentially offer protection against infections. Many antidepressants have shown FIASMA activity. METHODS: We conducted a cohort study using primary-care data from the UK-based Clinical Practice Research Datalink (2000-2021). We assessed the association of composite diagnosed acute infections in new users of fluoxetine, sertraline, paroxetine, or venlafaxine aged 18-80 years compared to citalopram. We compared SARS-CoV-2 infections between groups in a secondary analysis. We estimated incidence rates (IR) and IR ratios (IRR) of acute infections in four pairwise comparisons using negative binomial regression. We applied propensity score (PS) fine stratification to control for confounding. RESULTS: In the PS-weighted cohorts, we included 353,138 fluoxetine, 222,463 sertraline, 69,963 paroxetine, 32,608 venlafaxine, and between 515,996 and 516,583 new citalopram users. PS-weighted IRs ranged between 76.8 acute infections /1000 person-years (py) (sertraline) and 98.9 infections/1000 py (citalopram). We observed PS-weighted IRRs around unity for paroxetine (0.97, 95 % CI, 0.95-1.00), fluoxetine (0.94, 95 % CI, 0.92-0.95), and venlafaxine (0.90, 95 % CI, 0.87-0.94) vs citalopram. Reduced IRR for sertraline vs citalopram (0.84, 95 % CI, 0.82-0.85), became null within subgroups by cohort entry date. In the analysis of SARS-CoV-2 infection, no statistically relevant risk reduction was seen. LIMITATIONS: Analysis not limited to patients with diagnosed depression, possible underestimation of infection incidence, and unclear FIASMA activity of citalopram. CONCLUSIONS: Fluoxetine, sertraline, paroxetine, and venlafaxine were not associated with a reduced risk of acute infection when compared with the presumably weak FIASMA citalopram.

Machine Learning-Based Prediction of Escitalopram and Sertraline Side Effects With Pharmacokinetic Data in Children and Adolescents.

Selective serotonin reuptake inhibitors (SSRI) are the first-line pharmacologic treatment for anxiety and depressive disorders in children and adolescents. Many patients experience side effects that are difficult to predict, are associated with significant morbidity, and can lead to treatment discontinuation. Variation in SSRI pharmacokinetics could explain differences in treatment outcomes, but this is often overlooked as a contributing factor to SSRI tolerability. This study evaluated data from 288 escitalopram-treated and 255 sertraline-treated patients ≤ 18 years old to develop machine learning models to predict side effects using electronic health record data and Bayesian estimated pharmacokinetic parameters. Trained on a combined cohort of escitalopram- and sertraline-treated patients, a penalized logistic regression model achieved an area under the receiver operating characteristic curve (AUROC) of 0.77 (95% confidence interval (CI): 0.66-0.88), with 0.69 sensitivity (95% CI: 0.54-0.86), and 0.82 specificity (95% CI: 0.72-0.87). Medication exposure, clearance, and time since the last dose increase were among the top features. Individual escitalopram and sertraline models yielded an AUROC of 0.73 (95% CI: 0.65-0.81) and 0.64 (95% CI: 0.55-0.73), respectively. Post hoc analysis showed sertraline-treated patients with activation side effects had slower clearance (P = 0.01), which attenuated after accounting for age (P = 0.055). These findings raise the possibility that a machine learning approach leveraging pharmacokinetic data can predict escitalopram- and sertraline-related side effects. Clinicians may consider differences in medication pharmacokinetics, especially during dose titration and as opposed to relying on dose, when managing side effects. With further validation, application of this model to predict side effects may enhance SSRI precision dosing strategies in youth.

The efficacy and safety of sertraline in maintenance hemodialysis patients with depression: A randomized controlled study.

OBJECTIVE: To determine the efficacy and safety of sertraline in maintenance hemodialysis (MHD) patients with depression. METHODS: A randomized controlled trial was conducted involving 125 MHD patients with depression. The treatment group received sertraline, while the control group did not receive any antidepressant treatment. After 12 weeks, we compared the changes in the Hamilton Depression Rating Scale (HAMD), the Medication Adherence Report Scale-5 (MARS-5), the Mini Nutritional Assessment short-form (MNA-SF), the Kidney Disease Quality of Life-36 (KDQOL-36) scores, selected clinical and laboratory indicators, and the incidence of drug-related adverse reactions between the two groups. RESULTS: After 12 weeks of treatment, the HAMD scores of patients in the treatment group significantly decreased compared to before treatment and were lower than those in the control group. The KDQOL-36, MARS-5, and MNA-SF scores in the treatment group also significantly improved compared to before treatment and were superior to those in the control group. Albumin and hemoglobin levels in the treatment group significantly increased, while C-reactive protein significantly decreased. The incidence of nausea was slightly higher in the treatment group, and was mostly relieved after reducing the dosage of sertraline. LIMITATIONS: This study is a single-center, small-sample study with a relatively short duration of treatment and follow-up. CONCLUSIONS: Sertraline can alleviate depressive symptoms, and improve the quality of life and treatment compliance of MHD patients, while improving chronic inflammation, malnutrition, and anemia. However, starting with a low dose and reducing the maintenance dose is recommended when administering sertraline.

Sertraline for anxiety in adults with a diagnosis of autism (STRATA): study protocol for a pragmatic, multicentre, double-blind, placebo-controlled randomised controlled trial.

BACKGROUND: Selective serotonin reuptake inhibitors (SSRIs) are commonly prescribed to manage anxiety in adults with an autism diagnosis. However, their effectiveness and adverse effect profile in the autistic population are not well known. This trial aims to determine the effectiveness and cost-effectiveness of the SSRI sertraline in reducing symptoms of anxiety and improving quality of life in adults with a diagnosis of autism compared with placebo and to quantify any adverse effects. METHODS: STRATA is a two-parallel group, multi-centre, pragmatic, double-blind, randomised placebo-controlled trial with allocation at the level of the individual. It will be delivered through recruiting sites with autism services in 4 regional centres in the United Kingdom (UK) and 1 in Australia. Adults with an autism diagnosis and a Generalised Anxiety Disorder Assessment (GAD-7) score ≥ 10 at screening will be randomised 1:1 to either 25 mg sertraline or placebo, with subsequent flexible dose titration up to 200 mg. The primary outcome is GAD-7 scores at 16 weeks post-randomisation. Secondary outcomes include adverse effects, proportionate change in GAD-7 scores including 50% reduction, social anxiety, obsessive-compulsive symptoms, panic attacks, repetitive behaviours, meltdowns, depressive symptoms, composite depression and anxiety, functioning and disability and quality of life. Carer burden will be assessed in a linked carer sub-study. Outcome data will be collected using online/paper methods via video call, face-to-face or telephone according to participant preference at 16, 24 and 52 weeks post-randomisation, with brief safety checks and data collection at 1-2, 4, 8, 12 and 36 weeks. An economic evaluation to study the cost-effectiveness of sertraline vs placebo and a QuinteT Recruitment Intervention (QRI) to optimise recruitment and informed consent are embedded within the trial. Qualitative interviews at various times during the study will explore experiences of participating and taking the trial medication. DISCUSSION: Results from this study should help autistic adults and their clinicians make evidence-based decisions on the use of sertraline for managing anxiety in this population.

Artificial intelligence-based model for dose prediction of sertraline in adolescents: a real-world study.

BACKGROUND: Variability exists in sertraline pharmacokinetic parameters in individuals, especially obvious in adolescents. We aimed to establish an individualized dosing model of sertraline for adolescents with depression based on artificial intelligence (AI) techniques. METHODS: Data were collected from 258 adolescent patients treated at the First Hospital of Hebei Medical University between December 2019 to July 2022. Nine different algorithms were used for modeling to compare the prediction abilities on sertraline daily dose, including XGBoost, LGBM, CatBoost, GBDT, SVM, ANN, TabNet, KNN, and DT. Performance of four dose subgroups (50 mg, 100 mg, 150 mg, and 200 mg) were analyzed. RESULTS: CatBoost was chosen to establish the individualized medication model with the best performance. Six important variables were found to be correlated with sertraline dose, including plasma concentration, PLT, MPV, GL, A/G, and LDH. The ROC curve and confusion matrix exhibited the good prediction performance of CatBoost model in four dose subgroups (the AUC of 50 mg, 100 mg, 150 mg, and 200 mg were 0.93, 0.81, 0.93, and 0.93, respectively). CONCLUSION: The AI-based dose prediction model of sertraline in adolescents with depression had a good prediction ability, which provides guidance for clinicians to propose the optimal medication regimen.

Potential Involvement of Sulfotransferase in the Mechanism of Lamotrigine-induced Skin Rash.

The mechanism of drug-induced skin rash is not well understood. Circumstantial evidence suggests that the covalent binding of a reactive metabolite is involved in the mechanism of most idiosyncratic drug reactions. However, there is a limited quantity of drug metabolizing enzymes in the skin, except for sulfotransferases. It is possible that some drugs are metabolized to reactive sulfate metabolites that are responsible for skin rashes. For example, nevirapine-induced skin rash involves metabolism of nevirapine to 12-hydroxy-nevirapine, which is further metabolized by sulfotransferase in the skin to a reactive benzylic sulfate that covalently binds to proteins. The working hypothesis is that lamotrigine, valdecoxib, and sertraline skin rashes involve the formation of reactive sulfate in the skin. Lamotrigine-N-oxide, hydroxy-valdecoxib, and hydroxy-sertraline were tested as substrates with known human sulfotransferases. Hydroxy-valdecoxib and the benzylic alcohol metabolite of sertraline were not substrates for human sulfotransferases. Therefore, this pathway is presumably not involved in the mechanism by which they cause skin rashes. In contrast, lamotrigine-N-oxide is a substrate for several human sulfotransferases and the sulfate is chemically reactive. Furthermore, lamotrigine-N-sulfate not only alkylates proteins as we described previously but also forms the sulfate of tyrosine, suggesting another possible mechanism for protein modification. This study has further added to the understanding of the potential of the sulfotransferase pathways and protein sulfation to play a role in drug-induced skin rash.

Antidepressants for the prevention of depression following first-episode psychosis (ADEPP): study protocol for a multi-centre, double-blind, randomised controlled trial.

BACKGROUND: Depressive episodes are common after first-episode psychosis (FEP), affecting more than 40% of people, adding to individual burden, poor outcomes, and healthcare costs. If the risks of developing depression were lower, this could have a beneficial effect on morbidity and mortality, as well as improving outcomes. Sertraline is a selective serotonin reuptake inhibitor and a common first-line medication for the treatment of depression in adults. It has been shown to be safe when co-prescribed with antipsychotic medication, and there is evidence that it is an effective treatment for depression in established schizophrenia. We present a protocol for a multi-centre, double-blind, randomised, placebo-controlled clinical trial called ADEPP that aims to investigate the efficacy and cost-effectiveness of sertraline in preventing depression after FEP. METHODS: The recruitment target is 452 participants between the ages of 18 and 65 years who are within 12 months of treatment initiation for FEP. Having provided informed consent, participants will be randomised to receive either 50 mg of sertraline daily or matched placebo for 6 months, in addition to treatment as usual. The primary outcome measure will be a comparison of the number of new cases of depression between the treatment and placebo arms over the 6-month intervention phase. Secondary outcomes include suicidal behaviour, anxiety, rates of relapse, functional outcome, quality of life, and resource use. DISCUSSION: The ADEPP trial will test whether the addition of sertraline following FEP is a clinically useful, acceptable, and cost-effective way of improving outcomes following FEP.

Fetal SSRI antidepressant exposure and infant sleep: Findings from the MPEWS pregnancy cohort study.

This longitudinal study examines the association between fetal Selective Serotonergic Reuptake Inhibitor antidepressant exposure and infant sleep behaviours at six and 12 months of age and focus on three of the most commonly prescribed antidepressants in pregnancy. This study utilises data on 698 women recruited at less than 20 weeks of pregnancy and are followed up at six and 12 months postpartum. Women were recruited into one of three groups: those taking either sertraline, citalopram or escitalopram antidepressants in pregnancy (n = 85); women with a depressive disorder who were not taking antidepressants (non-medicated depressed, NMD; n = 82); and, and a control group of women (n = 531). At six and 12 months, data were collected on breastfeeding and sleep location and infant sleep was measured using the Brief Infant Sleep Questionnaire. Antidepressants sertraline, escitalopram and citalopram were not associated with increased infant waking or time awake. However, sertraline was associated with longer time for an infant to go to sleep. This study provides reassurance that SSRI antidepressants and, in particular, sertraline, escitalopram and citalopram are not associated with infant sleep behaviours that are commonly regarded as problematic including night waking. Further replication of these findings, including with direct measures of infant sleep, are recommended.

Fetal cardiac safety of sertraline use during pregnancy.

INTRODUCTION: Fetal cardiac safety of sertraline is controversial even though it is among the most frequently used antidepressants in pregnancy. Sertraline could theoretically affect the fetal heart resulting in malformations or more subtle changes, but studies evaluating fetal cardiac safety are prone to a number of systematic and random errors. AREAS COVERED: The objective of this review is to evaluate the fetal cardiac safety profile of sertraline in pregnancy. A literature review included articles until November 2022 in Medline with no time or language limitations. EXPERT OPINION: Sertraline is associated with septal heart malformations, but not with more severe heart malformations. The association may be causal or at least partly related to systematic errors, including confounding by indication. Regardless of the causal mechanism, the association should not limit well-indicated treatments of maternal depression. The few available studies on fetal heart function is reassuring. There are no human data on the long-term effects on offspring cardiac function, but the teratogenic and fetal heart function studies do not imply risks of any major cardiac problems later in life. Interactions with other medication may, however, alter the risks associated with any medication in pregnancy, and information and surveilence systems taking this into account is much needed.

l-theanine adjunct to sertraline for major depressive disorder: A randomized, double-blind, placebo-controlled clinical trial.

BACKGROUND: Unsatisfactory responses to major depressive disorder (MDD) therapeutics available necessitated up-to-date treatment approaches. This study sought to investigate the efficacy and tolerability of adjunctive l-theanine, a green tea constituent with neuropsychotropic effects, for MDD. METHODS: Sixty MDD (DSM-5) patients were equally assigned to receive sertraline (100 mg/d) plus either l-theanine (200 mg/d) or matched placebo in a six-week randomized, parallel-group, double-blind, placebo-controlled study. The participants were assessed using the Hamilton depression rating scale (HDRS) at baseline and weeks 2, 4, and 6. Changes in scores, early improvement, response and remission rates, and adverse events were compared between the groups. RESULTS: Twenty-five participants in each group, a total of 50 patients, completed the study. All baseline characteristics were similar between the groups. The general linear model repeated-measures analysis demonstrated a significant time-treatment interaction effect for HDRS during the trial (p-value = 0.014), indicating more remarkable symptom improvement in the l-theanine group. A greater reduction in HDRS scores was observed in the l-theanine group from baseline to weeks 2, 4, and 6 (p-values = 0.02, 0.03, and 0.01, respectively). All patients responded to sertraline plus l-theanine until week 6. l-theanine was superior to placebo regarding response to treatment and remission rates at week 6 (p-values = 0.05 and 0.02, respectively). The frequency of side effects was comparable between the groups. LIMITATIONS: The small sample size and short study period were the limitations. CONCLUSIONS: l-theanine adjunct to sertraline outperforms placebo in treating MDD in a safe manner. Further long-term, large-scale studies are recommended to confirm this evidence.

Effects of Long-Term Sertraline Use on Pediatric Growth and Development: The Sertraline Pediatric Registry for The Evaluation of Safety (SPRITES).

Objective: To describe the results of the Sertraline Pediatric Registry for The Evaluation of Safety (SPRITES) outcome measures of cognitive, emotional, and physical development following long-term treatment with sertraline (for up to 3 years) in children and adolescents aged 6-16 years. Methods: SPRITES was a long-term, multicenter, open-label, prospective observational study designed to compare physical and psychological development in pediatric patients exposed to sertraline (with or without psychotherapy) or psychotherapy alone in usual care settings. Data were summarized descriptively, and outcomes were evaluated using a marginal structural model. Results: Between April 2012 and September 2020, 941 patients across 44 U.S. sites participated in the study. At baseline, 695 participants were exposed to sertraline (physician prescribed) with or without psychotherapy, and 245 participants were exposed to psychotherapy alone. Of these, 432 participants (46.0%) completed the full 3-year study follow-up. No significant changes across time were found in standardized height, BRIEF (Behavior Rating Inventory of Executive Function), Trails B, and Tanner stage based on cumulative sertraline exposure or exposure since the last visit. Change in mean standardized weight across time was positively associated with both cumulative sertraline exposure (p = 0.02) and exposure since the last visit (p = 0.029). The mean changes from baseline across time in standardized weight were standard deviations of 0.02, 0.03, 0.16, and 0.17 at months 3, 6, 30, and 36, respectively. However, this finding was not observed in the mean change across time in standardized body mass index, which was not statistically significant. Conclusions: Results are consistent with normal development. Although a statistically significant finding for standardized weight was observed in comparative analyses, the magnitude of the change is small and observed at higher doses of sertraline only. No other significant differences were observed between the "sertraline" group and the "no pharmacological therapy" group on other primary outcome measures.

[Tiaoshen Jieyu acupuncture combined with sertraline hydrochloride tablet for post-stoke depression: a randomized controlled trial].

OBJECTIVE: To compare the clinical efficacy between Tiaoshen Jieyu acupuncture (acupuncture for regulating mind and relieving depression) combined with sertraline hydrochloride tablet and simple sertraline hydrochloride tablet for post-stroke depression (PSD). METHODS: A total of 76 patients with PSD were randomized into an observation group (38 cases, 6 cases dropped off) and a control group (38 cases, 4 cases dropped off). Both groups were treated with conventional treatment i.e. controlling blood pressure and anti-inflammation. Sertraline hydrochloride tablet was given orally in the control group, 20 mg a time, once a day. On the basis of the treatment in the control group, Tiaoshen Jieyu acupuncture was applied at Baihui (GV 20), Yintang (GV 24+), Neiguan (PC 6), Taichong (LR 3), etc. in the observation group, Baihui (GV 20) and Yintang (GV 24+) were connected to electroacupuncture, with disperse-dense wave, 2 Hz/100 Hz in frequency, 30 min a time, once a day, 6 times a week. Treatment of 8 weeks was required in both groups. Before and after treatment, the scores of Hamilton depression scale (HAMD), National Institutes of Health stroke scale (NIHSS), Barthel index (BI) and Pittsburgh sleep quality index (PSQI) were observed respectively, the therapeutic efficacy and rate of adverse reactions were evaluated in the two groups. RESULTS: After treatment, the scores of HAMD, NIHSS and PSQI were lower while BI scores were higher than those before treatment in both groups (P<0.05); the scores of HAMD, NIHSS and PSQI in the observation group were lower while BI score was higher than those in the control group (P<0.05). The total effective rate was 93.8% (30/32) in the observation group, which was higher than 70.6% (24/34) in the control group (P<0.05). The rate of adverse reactions was 9.4% (3/32) in the observation group, which was lower than 32.4% (11/34) in the control group (P<0.05). CONCLUSION: Tiaoshen Jieyu acupuncture combined with sertraline hydrochloride tablet can improve the depression degree, neurological function, activity of daily living and sleep quality in patients with post-stroke depression, the clinical efficacy is superior to simple sertraline hydrochloride, and can alleviate the adverse reactions caused by medication.

Adverse Effects of Antidepressant Medications and their Management in Children and Adolescents.

INTRODUCTION: Selective serotonin reuptake inhibitors (SSRIs) and, to a lesser extent, serotonin-norepinephrine reuptake inhibitors (SNRIs) are the cornerstone of pharmacotherapy for children and adolescents with anxiety and depressive disorders. These medications alleviate symptoms and restore function for many youths; however, they are associated with a distinct adverse effect profile, and their tolerability may complicate treatment or lead to discontinuation. Yet, SSRI/SNRI tolerability has received limited attention in the pediatric literature. METHODS: This review examines the early- (e.g., activation, gastrointestinal symptoms, sedation) and late-emerging (e.g., weight gain) adverse effects of SSRIs and some SNRIs in pediatric patients. RESULTS: We provide a framework for discussing SSRI/SNRI tolerability with patients and their families and describe the pharmacologic basis, course, and predictors of adverse events in youth. Strategies to address specific tolerability concerns are presented. For selected adverse events, using posterior simulation of mean differences over time, we describe their course based on Physical Symptom Checklist measures in a prospective, randomized trial of anxious youth aged 7-17 years who were treated with sertraline (n = 139) or placebo (n = 76) for 12 weeks in the Child/Adolescent Anxiety Multimodal Study (CAMS). MAIN RESULTS: In CAMS, the relative severity/burden of total physical symptoms (p < 0.001), insomnia (p = 0.001), restlessness (p < 0.001), nausea (p = 0.002), abdominal pain (p < 0.001), and dry mouth (p = 0.024) decreased from baseline over 12 weeks of sertraline treatment, raising the possibility that these symptoms are transient. No significant changes were observed for sweating (p = 0.103), constipation (p = 0.241), or diarrhea (p = 0.489). Finally, we review the antidepressant withdrawal syndrome in children and adolescents and provide guidance for SSRI discontinuation, using pediatric pharmacokinetic models of escitalopram and sertraline-two of the most used SSRIs in youth. CONCLUSION: SSRI/SNRIs are associated with both early-emerging (often transient) and late-emerging adverse effects in youth. Pharmacokinetically-informed appraoches may address some adverse effects and inform SSRI/SNRI discontinuation strategies.

Sertraline-Induced Tics: A Case Report and Narrative Review.

This brief report describes the case of a 16-year-old girl who was commenced on sertraline for anxiety and depression, and subsequently developed severe and debilitating motor tics. Cessation of sertraline was associated with the resolution of tics; after this, paroxetine was trialled and well tolerated with good response of targeted symptoms and without re-emergence of tics. A narrative literature review yielded a retrospective observational study and eight single case reports on selective serotonin receptor inhibitor-induced motor tics (three in adolescents and five in adults). Tics are not commonly considered as a side-effect of SSRIs. This case report is novel is several aspects: the tics emergence was immediate whereas previous cases were delayed; the tics symptoms were measured and quantified by a validated scale; a dose-response relationship was observed; to our knowledge, our case was the first adolescent female reported; and finally, paroxetine was well-tolerated as a substitute, although it is unclear whether the observed tics-sparing effect is co-incidental, ideocratic or can be replicated.

Predictors of relapse of psychotic depression: Findings from the STOP-PD II randomized clinical trial.

Psychotic depression has a high rate of relapse. The study aims were to identify a prediction model of risk of relapse of psychotic depression and examine whether predictors moderated the effect of treatment on relapse. One hundred and twenty-six men and women aged 18-85 years, who experienced sustained remission or near-remission of psychotic depression with sertraline plus olanzapine, participated in a 36-week randomized controlled trial that compared sertraline plus olanzapine with sertraline plus placebo in preventing relapse (NCT01427608). Cox regression analyses were performed to identify significant predictors of relapse and to model the combined role of significant predictors. Concordance statistic was calculated to determine the accuracy of the best fit multivariable models in predicting relapse. Finally, interaction terms were tested for each significant predictor to examine whether they moderated the effect of treatment on risk of relapse. Lifetime number of depressive episodes, severity of residual depressive symptoms at the time of randomization, and psychomotor disturbance both at acute enrollment when participants were depressed and at the time of randomization predicted risk of relapse. Multivariable models had 69-70% accuracy in predicting relapse. Psychomotor disturbance was associated with increased risk of relapse in the sertraline plus olanzapine group compared with sertraline plus placebo, whereas the other predictors did not moderate the effect of treatment on relapse. Future research is needed to determine whether a combination of clinical and biological variables can further increase the accuracy of prediction of relapse of psychotic depression.
