Abstract

Importance: Depressive disorders (DDs), anxiety disorders (ADs), obsessive-compulsive disorder (OCD), and posttraumatic stress disorder (PTSD) are common mental disorders in children and adolescents. Objective: To examine the relative efficacy and safety of selective serotonin reuptake inhibitors (SSRIs), serotonin-norepinephrine reuptake inhibitors (SNRIs), and placebo for the treatment of DD, AD, OCD, and PTSD in children and adolescents. Data Sources: PubMed, EMBASE, PsycINFO, Web of Science, and Cochrane Database from inception through August 7, 2016. Study Selection: Published and unpublished randomized clinical trials of SSRIs or SNRIs in youths with DD, AD, OCD, or PTSD were included. Trials using other antidepressants (eg, tricyclic antidepressants, monoamine oxidase inhibitors) were excluded. Data Extraction and Synthesis: Effect sizes, calculated as standardized mean differences (Hedges g) and risk ratios (RRs) for adverse events, were assessed in a random-effects model. Main Outcomes and Measures: Primary outcomes, as defined by authors on preintervention and postintervention data, mean change data, and adverse event data, were extracted independently by multiple observers following PRISMA guidelines. Results: Thirty-six trials were eligible, including 6778 participants (3484 [51.4%] female; mean [SD] age, 12.9 [5.1] years); 17 studies for DD, 10 for AD, 8 for OCD, and 1 for PTSD. Analysis showed that SSRIs and SNRIs were significantly more beneficial compared with placebo, yielding a small effect size (g = 0.32; 95% CI, 0.25-0.40; P < .001). Anxiety disorder (g = 0.56; 95% CI, 0.40-0.72; P < .001) showed significantly larger between-group effect sizes than DD (g = 0.20; 95% CI, 0.13-0.27; P < .001). This difference was driven primarily by the placebo response: patients with DD exhibited significantly larger placebo responses (g = 1.57; 95% CI, 1.36-1.78; P < .001) compared with those with AD (g = 1.03; 95% CI, 0.84-1.21; P < .001). The SSRIs produced a relatively large effect size for ADs (g = 0.71; 95% CI, 0.45-0.97; P < .001). Compared with participants receiving placebo, patients receiving an antidepressant reported significantly more treatment-emergent adverse events (RR, 1.07; 95% CI, 1.01-1.12; P = .01 or RR, 1.49; 95% CI, 1.22-1.82; P < .001, depending on the reporting method), severe adverse events (RR, 1.76; 95% CI, 1.34-2.32; P < .001), and study discontinuation due to adverse events (RR, 1.79; 95% CI, 1.38-2.32; P < .001). Conclusions and Relevance: Compared with placebo, SSRIs and SNRIs are more beneficial than placebo in children and adolescents; however, the benefit is small and disorder specific, yielding a larger drug-placebo difference for AD than for other conditions. Response to placebo is large, especially in DD. Severe adverse events are significantly more common with SSRIs and SNRIs than placebo.

  • Many patients do not respond to first-line SSRIs, and most experience significant side effects from them.

    “Unfortunately, current therapeutic tools have failed to reduce the prevalence of depression, with many patients not responding to, and most having significant side effects from, first-line treatments such as selective serotonin reuptake inhibitors (SSRIs)”

    From Mechanisms of ketamine and its metabolites as antidepressants (2022) · cites this paper as Locher et al., 2017

    The Introduction identifies SSRIs as first-line pharmaceutical treatments for the pediatric disorders studied. The Discussion reports a small, disorder-dependent benefit, and Results > Side Effect Analysis finds more adverse events with antidepressants than placebo. Neither passage establishes that many patients fail to respond to SSRIs or that most experience significant side effects; the study also concerns children and adolescents, not patients generally.

  • Antidepressant-treated glutamate levels are positively correlated with Hamilton Depression Rating Scale scores.

    “While this reduction does not lower glutamate levels to the same concentration as healthy controls, it has been shown that antidepressant-treated glutamate levels are positively correlated with Hamilton Depression Rating Scale scores187.”
  • Antidepressants are indicated for depressive disorders, anxiety disorders, PTSD, premenstrual dysphoric disorder, OCD, bulimia nervosa, and binge-eating disorder.

    “Antidepressants are indicated and used for depressive disorders, anxiety disorders, posttraumatic stress disorder, premenstrual dysphoric disorder, obsessive-compulsive disorder, bulimia nervosa, and binge-eating disorder, among others.[3][4][5]”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
