    OBJECTIVE: This study aimed to determine if personality disorder (PD) predicted functional outcomes in patients with major depressive disorder (MDD). METHODS: Data (n=71) from a double-blind, randomized, placebo-controlled 12-week trial assessing the efficacy of 200 mg/day adjunctive minocycline for MDD were examined. PD was measured using the Standardized Assessment of Personality Abbreviated Scale. Outcome measures included Clinical Global Impression - Improvement (CGI-I), Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q), Social and Occupational Functioning Scale (SOFAS), and Range of Impaired Functioning (RIFT). Analysis of covariance was used to examine the impact of PD (dichotomized factor [≥ 3] or continuous measure) on the outcome measures-treatment group correlation. RESULTS: PD was identified in 69% of the sample. After adjusting for age, sex, and baseline scores for each of the outcome measures, there was no significant difference between participants with and without PD on week 12 scores for any of the outcome measures (all p > 0.14). CONCLUSION: In this secondary analysis of a primary efficacy study, PD was a common comorbidity among those with MDD, but was not a significant predictor of functional outcomes. This study adds to the limited literature on PD in randomized controlled trials for MDD. CLINICAL TRIAL REGISTRATION: ACTRN12612000283875.

    INTRODUCTION: Due to the anti-inflammatory, antioxidant and anti-apoptotic properties of minocycline, clinical trials have evaluated the potential of this drug to treat several psychiatric and neurological disorders, including major depressive disorder, schizophrenia, bipolar disorder, stroke and amyotrophic lateral sclerosis. This protocol proposes a systematic review (and potential meta-analysis) that aims to identify and critically evaluate randomised controlled trials of minocycline for treating psychiatric and neurological disorders. METHODS AND ANALYSIS: PubMed, Embase, Cochrane Central Register of Controlled Clinical Trials, PsycINFO and Cumulative Index to Nursing and Allied Health Literature (CINAHL) will be used to identify randomised controlled trials that used minocycline to treat psychiatric and neurological disorders. Double-blind, randomised, controlled, clinical trials of participants aged 18 years or older and written in English will be included in the review. Data will be extracted by two independent reviewers. Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines will be followed and the Cochrane Collaboration's 'Risk of Bias' tool will be used to assess the risk of bias in all studies included in the systematic review. The Grading of Recommendations, Assessment, Development and Evaluation system will be used to access the overall quality of the level of evidence of the studies. If sufficient evidence is identified, a meta-analysis will be conducted using the standardised mean difference approach and reported with 95% CIs. Heterogeneity of evidence will be evaluated using the I2 model. ETHICS AND DISSEMINATION: This systematic review will evaluate only published data; therefore, ethical approval is not required. The systematic review will be published in a peer-reviewed journal and presented at relevant research conferences. TRIAL REGISTRATION NUMBER: CRD42020153292.

    BACKGROUND: Inflammation contributes to the pathophysiology of major depressive disorder (MDD), and anti-inflammatory strategies might therefore have therapeutic potential. This trial aimed to determine whether adjunctive aspirin or rosuvastatin, compared with placebo, reduced depressive symptoms in young people (15-25 years). METHODS: YoDA-A, Youth Depression Alleviation with Anti-inflammatory Agents, was a 12-week triple-blind, randomised, controlled trial. Participants were young people (aged 15-25 years) with moderate to severe MDD (MADRS mean at baseline 32.5 ± 6.0; N = 130; age 20.2 ± 2.6; 60% female), recruited between June 2013 and June 2017 across six sites in Victoria, Australia. In addition to treatment as usual, participants were randomised to receive aspirin (n = 40), rosuvastatin (n = 48), or placebo (n = 42), with assessments at baseline and weeks 4, 8, 12, and 26. The primary outcome was change in the Montgomery-Åsberg Depression Rating Scale (MADRS) from baseline to week 12. RESULTS: At the a priori primary endpoint of MADRS differential change from baseline at week 12, there was no significant difference between aspirin and placebo (1.9, 95% CI (- 2.8, 6.6), p = 0.433), or rosuvastatin and placebo (- 4.2, 95% CI (- 9.1, 0.6), p = 0.089). For rosuvastatin, secondary outcomes on self-rated depression and global impression, quality of life, functioning, and mania were not significantly different from placebo. Aspirin was inferior to placebo on the Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q-SF) at week 12. Statins were superior to aspirin on the MADRS, the Clinical Global Impressions Severity Scale (CGI-S), and the Negative Problem Orientation Questionnaire scale (NPOQ) at week 12. CONCLUSIONS: The addition of either aspirin or rosuvastatin did not to confer any beneficial effect over and above routine treatment for depression in young people. Exploratory comparisons of secondary outcomes provide limited support for a potential therapeutic role for adjunctive rosuvastatin, but not for aspirin, in youth depression.
