Abstract
PURPOSE To assess the effect of exposure to fluvoxamine around the COVID-19 diagnosis on subsequent hospitalizations and mortality in COVID-19 outpatients in a real-life setting. METHODS Using nationwide administrative data, we identified adult COVID-19 outpatients diagnosed up to August 15, 2021 and conducted two cohort studies. Study 1 included subjects prescribed fluvoxamine around the index COVID-19 diagnosis (Cohort A), their peers suffering similar psychiatric difficulties but not prescribed fluvoxamine (Cohort B) and those free of psychiatric difficulties/treatments (Cohort C). Study 2 included subjects prescribed fluvoxamine (Cohort Fluvoxamine) and their peers prescribed paroxetine (Cohort Paroxetine). Cohorts were mutually exactly matched and incidence of COVID-19-related hospitalization, 30-day all-cause hospitalization and of COVID-19-related mortality was estimated. RESULTS Of the 416,030 first-episode outpatients, Study 1 included 1016 Cohort A, 95,984 Cohort B and 275,804 Cohort C patients. Matched Cohort A (n = 749) vs. Cohort B (n = 31,336) relative risks (95%CI/CrI), frequentist and Bayes with skeptical, otpimistic and pesimistic priors, were COVID-related hospitalization 1.37 (0.56-3.33), 1.15 (0.55-2.11), 1.03 (0.56.1.96) and 1.43 (0.63-2.94), respectively; 30-day all-cause hospitalization 1.88 (0.76-4.67), 1.76 (1.39-2.25), 1.76 (1.39-2.24) and 1.86 (1.43-2.38), respectively; COVID-19-related mortality 0.73 (0.35-1.55), 0.93 (0.53-1.76), 0.79 (0.40-1.54) and 0.88 (0.37-2.11), respectively. Matched Cohort A vs. C (866 vs. 222,792) comparison yielded similar estimates, as did the matched Cohort Fluvoxamine vs. Paroxetine comparison in Study 2 (344 of 994 matched to 535 of 1796 patients). CONSLUSION Outpatients prescribed fluvoxamine around the time of COVID-19 diagnosis were not at a reduced risk of hospitalizations and mortality compared to their non-prescribed peers.

Abstract
PURPOSE To estimate annual incidence and prevalence of Treatment-Resistant Depression (TRD) in France. METHODS We identified all adult patients (≥ 18 years) with a TRD episode between 1 January 2012 and 31 December 2014 in the EGB (Échantillon généraliste des bénéficiaires), a permanent random sample of the French nationwide claims database. After a 6-month washout period without hospitalization for depression or any antidepressants (AD), and after exclusion of psychotic or bipolar affective disorders, Parkinson's disease and dementia, a TRD episode was defined by three successive sequences of different AD over a 3-month treatment period (6 months for a sensitive analysis), with at least 3 weeks before each sequence change and a Medication Possession Ratio ≥ 80%; or by the dispensing of >two different AD together; or of an AD with a potentiator (lithium, antiepileptic drugs, antipsychotic drugs, thyroid hormones) over the same treatment period. The annual incidence rate was estimated from 2012 to 2014 and the prevalence using a Gamma parametric function based on treatment duration and a 30-year prediction. RESULTS Between 2012 and 2014, 700 patients were identified in EGB with a TRD episode. The mean age was 47.4 years (±15.3); 52.7% were women. Annual incidence and prevalence of TRD were estimated at 5.8 and 25.8 per 10 000 patients, respectively and at 7.8 and 37.6 per 10 000 patients, respectively in the sensitivity analysis. CONCLUSION This study provides the first population-based estimates for incidence and prevalence of TRD in France.

Abstract
The efficacy of the combination therapy with two antidepressants from different pharmacological families in patients with treatment-resistant depression has been reported in multiple studies. In this prospective 12-weeks open-label study, we assessed the effectiveness of the addition of reboxetine to 79 depressive outpatients diagnosed with major depressive disorder (MDD) according to the DSM-IV criteria who had previously not responded, or had done so only in a partial way, over 8 weeks of conventional treatment, in monotherapy, with duloxetine. Efficacy was assessed using the 21-item Hamilton Depression Rating Scale (HDRS) and the Clinical Global Impression-Improvement (CGI-I). Safety was evaluated by recording spontaneously reported adverse events. Data were analysed on an intent-to-treat basis, using the last-observation-carried-forward method. Mean HDRS reduction was 65.5% (P < 0.0001). The percentages of responders (>or=50% reduction in HDRS) and patients considered benefiting from complete remission (HDRS <or= 10 points) at week 12 were 76% and 69.3%, respectively. By the end of the treatment, the score of CGI-I decreased 68.5% (P < 0.0001). Percentage of patient improving (CGI < 4 points) was 95.8%. The most common non-serious adverse events were dry mouth, increased sweating, constipation and difficulty passing urine. The results of this study suggest that the combination strategy with reboxetine may be an effective and well-tolerated tool in duloxetine-resistant patients.

Abstract
OBJECTIVE Non-response to treatment with antidepressants (AD) is a clinical problem. METHOD The algorithm for pharmacological treatment of the Dutch multidisciplinary guideline for depression is compared with four other algorithms. RESULTS The Dutch algorithm consists of five subsequent steps. Treatment is started with one out of many optional ADs (step 1); in case of non-response after 4-10 weeks, best evidence is for switching to another AD (step 2); next step is augmentation with lithium as the best option (step 3); the next step is a monoamine oxidase inhibitor (MAOI) (step 4); and finally electroconvulsive therapy (step 5). There are major differences with other algorithms regarding timing of augmentation step, best agents for augmentation and role of MAOI. CONCLUSION Algorithms for AD treatment vary according to national and local preferences. Although the evidence for most of the treatment strategies is rather meagre, an AD algorithm appears to be an useful instrument in clinical practice.

Abstract
Major depressive disorder (MDD) is an illness of great morbidity that affects many people across the world. The current goal for treatment of MDD is to achieve remission (i.e., no depressive symptoms). However, despite scientific advances in the treatment for MDD, antidepressants as first-line agents yield only modest remission rates. In fact, a recent study indicated that only one out of three subjects who received a standard, first-line antidepressant attained remission. Not achieving remission from depressive symptoms increases the risk of a more chronic and debilitating course of illness with frequent recurrences. Although a number of reasons contribute to these modest outcomes, the presence of residual symptoms is a major problem. Residual symptoms are defined as symptoms that linger despite an adequate dose and duration of an antidepressant medication. This article reviews the prevalence and clinical impact of common residual symptoms and discusses the utility of aggressively addressing residual symptoms to enhance the efficacy of antidepressant medications.

Abstract
The past decade of efforts to find improved treatment for major depression has been dominated by genome-driven programs of rational drug discovery directed toward highly selective ligands for nonmonoaminergic agents. Selective drugs may prove beneficial for specific symptoms, for certain patient subpopulations, or both. However, network analyses of the brain and its dysfunction suggest that agents with multiple and complementary modes of action are more likely to show broad-based efficacy against core and comorbid symptoms of depression. Strategies for improved multitarget exploitation of monoaminergic mechanisms include triple inhibitors of dopamine, serotonin (5-HT) and noradrenaline reuptake, and drugs interfering with feedback actions of monoamines at inhibitory 5-HT(1A), 5-HT(1B) and possibly 5-HT(5A) and 5-HT(7) receptors. Specific subsets of postsynaptic 5-HT receptors mediating antidepressant actions are under study (e.g., 5-HT(4) and 5-HT(6)). Association of a clinically characterized antidepressant mechanism with a nonmonoaminergic component of activity is an attractive strategy. For example, agomelatine (a melatonin agonist/5-HT(2C) antagonist) has clinically proven activity in major depression. Dual neurokinin(1) antagonists/5-HT reuptake inhibitors (SRIs) and melanocortin(4) antagonists/SRIs should display advantages over their selective counterparts, and histamine H(3) antagonists/SRIs, GABA(B) antagonists/SRIs, glutamatergic/SRIs, and cholinergic agents/SRIs may counter the compromised cognitive function of depression. Finally, drugs that suppress 5-HT reuptake and blunt hypothalamo-pituitary-adrenocorticotrophic axis overdrive, or that act at intracellular proteins such as GSK-3beta, may abrogate the negative effects of chronic stress on mood and neuronal integrity. This review discusses the discovery and development of dual- and triple-acting antidepressants, focusing on novel concepts and new drugs disclosed over the last 2 to 3 years.

Abstract
BACKGROUND The large majority of depressed patients fail to remit on the first antidepressant prescribed. These patients with residual symptoms have higher relapse rates and poorer outcomes than those who remit. Treatment-resistant depression (TRD) is a therapeutic challenge for the clinician. Augmentation pharmacotherapy refers to the addition of drugs that are not standard antidepressants in order to enhance the effect of a classical antidepressant drug. The aim of this paper was to review the available evidence on the various augmenting agents that have been tested for efficacy in TRD. METHODS Electronic databases and relevant textbooks were searched and the information retrieved was integrated in this review. RESULTS Although augmentation strategies have been tested with various pharmacological agents, there are few controlled studies published. Lithium, triiodothyronine (T3), buspirone and pindolol have been most widely studied. Other agents include dopaminergic agents, atypical antipsychotics, psychostimulants, benzodiazepines/hypnotics, hormones and anticonvulsants. CONCLUSION The augmentation therapy with the best evidence was the lithium-antidepressant combination, especially in patients not responding to tricyclic agents. However, good results have also been reported with augmentation strategies involving T3 and buspirone.

Abstract
OBJECTIVE To study the impact of depressive disorders (DD) on health care expenditure and to measure associated comorbidity in patients in primary care settings (PCS) under normal clinical practice conditions. METHOD A retrospective cohort study was carried out. The study cohort consisted of outpatients aged over 14 years of age with an established diagnosis of DD (ICPC; P76) treated in a PC health centre during 2004. A comparative cohort was formed with the remaining outpatients without DD, treated in that health centre. Main factors for calculation were: age, gender, history/comorbidity and health resource use and the corresponding outpatient costs; drugs, diagnostic tests, visits to specialists and PC physicians. Multiple logistic regression analysis and ANCOVA models were used in order to adjust costs and comorbidities between the cohorts of patients. RESULTS A total of 64,072 subjects were assessed; 6,592 patients with DD [10.3% (CI: 8.2-12.4%), 74.5% (CI: 73.4%-75.6%) females]. DD outpatients displayed a higher number of episodes of comorbidities/year (mean +/- SD; 7.4 +/- 4.3 vs. 4.7 +/- 3.3, p < 0.0001) and global medical visits/patient/year (12.0 +/- 9.3 vs. 7.4 +/- 7.6, p < 0.0001). The main comorbidities associated to DD were neurological disorders [Odds ratio (95% CI); 2.1 (CI: 1.5-2.6), p < 0.0001], alcoholism [1.6 (CI: 1.3-1.9), p < 0.0001] and malignancies [1.3 (CI: 1.1-1.5), p < 0.0001]. DD were associated with significantly higher adjusted total costs; 1,083.8 euro (SEM; 8.4 euro) vs. 684.1 euro (3.4 euro), p < 0.0001. Higher costs were displayed for elderly patients. Sixty-two percent of the total cost was related to drugs. CONCLUSIONS Prevalence of DD was higher, particularly in women. Following adjustment in accordance with comorbidity, age and sex, DD outpatients used more health care resources and implied higher costs. Higher costs were associated with age.

Abstract
INTRODUCTION Clonazepam has been shown to be an effective supplementary treatment for depression. Thus, it would be useful to determine which patient characteristics are associated with response to clonazepam. AIMS The purpose of this study was to examine the possible predictors of response to clonazepam in the treatment of depression. METHOD A retrospective cohort analysis was carried out in 120 patients with protracted depression who were being treated with clonazepam. RESULTS A variety of clinical factors, including age, gender, type of depression, frequency of episodes, family history; and daily dose of clonazepam, were analyzed as possible predictors of response to clonazepam. A Weibull regression analysis showed that the factors that best predicted improvement with clonazepam augmentation were negative family history of psychiatric illness (e(coef) = 0.378), daily clonazepam dose of 2.5-4.0 mg (e(coef) = 0.160), and unipolar depression (e(coef) = 0.147). CONCLUSIONS These factors should be considered when clonazepam augmentation therapy is selected for protracted depression.

Abstract
OBJECTIVES Treatment-resistant depression is a common occurrence in clinical practice as well as combination treatment with 2 different antidepressants. In the present case series, we study the effectiveness of the addition of reboxetine, during 12 weeks, to 14 outpatients diagnosed with major depressive disorder, according to Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition, Text Revision) criteria, who had previously failed to respond or who had only responded partially, over a period of 6 weeks, to conventional treatment with mirtazapine. METHODS Evaluation of antidepressant efficacy was carried out through the application of the 21-item Hamilton Depression Rating Scale (HDRS) and the Clinical Global Impressions-Global Improvement Scale (CGI-I). RESULTS The percentages of responders (HDRS>or=50%), patients in remission (HDRS<or=10), and improving (CGI-I absolute value<4) were 35.7%, 28.6%, and 64.3%, respectively. No serious side effects were observed during combination therapy, being more frequent dry mouth (2 cases). CONCLUSIONS The initial findings of our study show that reboxetine and mirtazapine may constitute an effective and low side effects combination.
