Polygenic risk scores of lithium response and treatment resistance in major depressive disorder. Transl Psychiatry 2023; 13:301. [PMID: 37770441 PMCID: PMC10539379 DOI: 10.1038/s41398-023-02602-3] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/06/2023] [Revised: 09/15/2023] [Accepted: 09/20/2023] [Indexed: 09/30/2023] Open
Abstract
Treatment response and resistance in major depressive disorder (MDD) are suggested to be heritable. Due to significant challenges in defining treatment-related phenotypes, our understanding of their genetic bases is limited. This study aimed to derive a stringent definition of treatment resistance and to investigate the genetic overlap between treatment response and resistance in MDD. Using electronic medical records on the use of antidepressants and electroconvulsive therapy (ECT) from Swedish registers, we derived the phenotype of treatment-resistant depression (TRD) and non-TRD within ~4500 individuals with MDD in three Swedish cohorts. Considering antidepressants and lithium are first-line treatment and augmentation used for MDD, respectively, we generated polygenic risk scores (PRS) of antidepressants and lithium response for individuals with MDD and evaluated their associations with treatment resistance by comparing TRD with non-TRD. Among 1778 ECT-treated MDD cases, nearly all (94%) used antidepressants before their first ECT and the vast majority had at least one (84%) or two (61%) antidepressants of adequate duration, suggesting these MDD cases receiving ECT were resistant to antidepressants. We did not observe a significant difference in the mean PRS of antidepressant response between TRD and non-TRD; however, we found that TRD cases had a significantly higher PRS of lithium response compared to non-TRD cases (OR = 1.10-1.12 under various definitions). The results support the evidence of heritable components in treatment-related phenotypes and highlight the overall genetic profile of lithium-sensitivity in TRD. This finding further provides a genetic explanation for lithium efficacy in treating TRD.

Case report: Treatment-resistant depression, multiple trauma exposure and suicidality in an adolescent female with previously undiagnosed Autism Spectrum Disorder. Front Psychiatry 2023; 14:1151293. [PMID: 37181890 PMCID: PMC10169628 DOI: 10.3389/fpsyt.2023.1151293] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/25/2023] [Accepted: 04/03/2023] [Indexed: 05/16/2023] Open
Abstract
High rates of co-occurring depression are commonly reported in youth with Autism Spectrum Disorder (ASD), especially in individuals without intellectual disability (ID). Depression in ASD undermines adaptive behavior and is associated with a higher risk of suicidality. Females with ASD may be particularly vulnerable due to their greater use of camouflaging strategies. Indeed, in comparison to males, ASD is underdiagnosed in females, despite higher rates of internalizing symptoms and suicidality. Trauma exposure may also play a role in the development of depressive symptoms in this population. Moreover, evidence for effective treatments of depression in autistic youth are lacking, with ASD individuals frequently experiencing low efficacy and side effects. We present the case of an adolescent female with previously undiagnosed ASD without ID, admitted for active suicidal plans and a treatment-resistant depression (TRD), occurred after a COVID-19 lockdown in the context of cumulative exposure to stressful life events. Comprehensive clinical assessments performed at intake confirmed severe depression with suicidality. Intensive psychotherapy and different changes in medications were carried out (SSRI, SNRI, SNRI + NaSSA, SNRI + aripiprazole), all of which were ineffective, with persistent suicidal thoughts, often requiring intensive individual monitoring. The patient was finally successfully treated with lithium augmentation of fluoxetine, with no side effects. During hospitalization she was also evaluated by an ASD specialized center, where a diagnosis of ASD was made according to the Autism Diagnostic Observation Schedule (ADOS) and the Autism Diagnostic Interview-Revised (ADI-R) scores, as well as to clinical judgment of a senior psychiatrist. The present case report shows that clinicians should not overlook undiagnosed autism as a possible cause of TRD, especially in females without ID, where higher rates of under diagnosis may be in part related to their greater use of camouflage. It also suggests that ASD underdiagnosis and resulting unmet needs may be involved in vulnerability to stressful experiences, depression, and suicidality. Furthermore, it shows the complexity of providing care to TRD in youth with autism, suggesting that an augmentation therapy with lithium, a commonly recommended therapeutic strategy for refractory depression in typically developing samples, may also be effective in this population.

Mood and behavior regulation: interaction of lithium and dopaminergic system. NAUNYN-SCHMIEDEBERG'S ARCHIVES OF PHARMACOLOGY 2023:10.1007/s00210-023-02437-1.

Abstract
Lithium is one of the most effect mood-stabilizing drugs prescribed especially for bipolar disorder. Lithium has wide range effects on different molecular factors and neural transmission including dopaminergic signaling. On the other hand, mesolimbic and mesocortical dopaminergic signaling is significantly involved in the pathophysiology of neuropsychiatric disorders. This review article aims to study lithium therapeutic mechanisms, dopaminergic signaling, and the interaction of lithium and dopamine. We concluded that acute and chronic lithium treatments often reduce dopamine synthesis and level in the brain. However, some studies have reported conflicting results following lithium treatment, especially chronic treatment. The dosage, duration, and type of lithium administration, and the brain region selected for measuring dopamine level were not significant differences in different chronic treatments used in previous studies. It was suggested that lithium has various mechanisms affecting dopaminergic signaling and mood, and that many molecular factors can be involved, including brain-derived neurotrophic factor (BDNF), cAMP response element-binding protein (CREB), β-catenin, protein kinase B (Akt), and glycogen synthase kinase-3 beta (GSK-3β). Thus, molecular effects of lithium can be the most important mechanisms of lithium that also alter neural transmissions including dopaminergic signaling in mesolimbic and mesocortical pathways.

Abstract
Lithium is a first-line medication for bipolar disorder (BD), but only one in three patients respond optimally to the drug. Since evidence shows a strong clinical and genetic overlap between depression and bipolar disorder, we investigated whether a polygenic susceptibility to major depression is associated with response to lithium treatment in patients with BD. Weighted polygenic scores (PGSs) were computed for major depression (MD) at different GWAS p value thresholds using genetic data obtained from 2586 bipolar patients who received lithium treatment and took part in the Consortium on Lithium Genetics (ConLi+Gen) study. Summary statistics from genome-wide association studies in MD (135,458 cases and 344,901 controls) from the Psychiatric Genomics Consortium (PGC) were used for PGS weighting. Response to lithium treatment was defined by continuous scores and categorical outcome (responders versus non-responders) using measurements on the Alda scale. Associations between PGSs of MD and lithium treatment response were assessed using a linear and binary logistic regression modeling for the continuous and categorical outcomes, respectively. The analysis was performed for the entire cohort, and for European and Asian sub-samples. The PGSs for MD were significantly associated with lithium treatment response in multi-ethnic, European or Asian populations, at various p value thresholds. Bipolar patients with a low polygenic load for MD were more likely to respond well to lithium, compared to those patients with high polygenic load [lowest vs highest PGS quartiles, multi-ethnic sample: OR = 1.54 (95% CI: 1.18-2.01) and European sample: OR = 1.75 (95% CI: 1.30-2.36)]. While our analysis in the Asian sample found equivalent effect size in the same direction: OR = 1.71 (95% CI: 0.61-4.90), this was not statistically significant. Using PGS decile comparison, we found a similar trend of association between a high genetic loading for MD and lower response to lithium. Our findings underscore the genetic contribution to lithium response in BD and support the emerging concept of a lithium-responsive biotype in BD.

Abstract
Background: Selective serotonin reuptake inhibitor (SSRI) antidepressant drugs are the first-line of treatment for major depressive disorder (MDD) but are effective in <70% of patients. Our earlier genome-wide studies indicated that two genes encoding for cell adhesion proteins, close homolog of L1 (CHL1) and integrin beta-3 (ITGB3), and microRNAs, miR-151a-3p and miR-221/222, are implicated in the variable sensitivity and response of human lymphoblastoid cell lines (LCL) from unrelated individuals to SSRI drugs. Methods: The microRNAs miR-221, miR-222, and miR-151-a-3p, along with their target gene binding sites, were explored in silico using miRBase, TargetScan, microRNAviewer, and the UCSC Genome Browser. Luciferase reporter assays were conducted for demonstrating the direct functional regulation of ITGB3 and CHL1 expression by miR-221/222 and miR-151a-3p, respectively. A human LCL exhibiting low sensitivity to paroxetine was utilized for studying the phenotypic effect of CHL1 regulation by miR-151a-3p on SSRI response. Results: By showing direct regulation of CHL1 and ITGB3 by miR-151a-3p and miR-221/222, respectively, we link these microRNAs and genes with cellular SSRI sensitivity phenotypes. We report that miR-151a-3p increases cell sensitivity to paroxetine via down-regulating CHL1 expression. Conclusions: miR-151a-3p, miR-221/222 and their (here confirmed) respective target-genes, CHL1 and ITGB3, are implicated in SSRI responsiveness, and possibly in the clinical response to antidepressant drugs.

Abstract
Suicide is a major global public health problem and the leading cause of injury mortality in the USA. Suicide is a complex phenomenon involving several systems and neurobiological pathways, with interacting genetic and environmental mechanisms. The literature on the neurobiology and pharmacotherapy of suicide has been limited. To date, no medications have proven efficacious for treating acute suicidal crises. There is an emerging literature supporting a rapid anti-suicidal effect of ketamine, a non-competitive N-methyl-D-aspartate (NMDA) glutamate receptor antagonist, among depressed patients with suicidal ideation. Potential ketamine's anti-suicidal effect mechanisms are linked to interruption of the kynurenine pathway and modulating pro-inflammatory cytokines exacerbation. However, available data are not sufficient for its routine integration in clinical practice, and larger and replicated randomized control studies are needed.

Abstract
Major depressive disorder (MDD) is a highly prevalent chronic psychiatric illness associated with significant morbidity, mortality, loss of productivity, and diminished quality of life. Typically, only a minority of patients responds to treatment and meet criteria for remission as residual symptoms may persist, the result of an inadequate course of treatment and/or the presence of persistent side effects. The foremost goal of treatment should be to restore patients to full functioning and eliminate or relieve all MDD symptoms, while being virtually free of troublesome side effects. The current available pharmacological options to manage persistent depressive symptoms include augmentation or adjunctive combination strategies, both of which target selected psychobiological systems and specific mood and somatic symptoms experienced by the patient. As well, non-pharmacological interventions including psychotherapies may be used in either first-line or adjunctive approaches. However, the evidence to date with respect to available adjunct therapies is limited by few studies and those published have utilized only a small number of subjects and lack enough data to allow for a consensus of expert opinion. This underlines the need for further longer term, large population-based studies and those that include comorbid populations, all of which are seen in real world community psychiatry.

Abstract
Major depressive disorder is a serious, recurrent condition with significant impact on a person's quality of life and functioning, which carries a significant risk of premature death due to suicide. There is evidence that supports the effectiveness of lithium as an augmentation strategy for treatment-resistant depression, as well as for reducing suicidality in this population. This review introduces several theories regarding the proposed mechanism behind lithium's anti-suicidal effects and summarizes a selection of the pertinent literature supporting lithium's beneficial effects on suicidality.

Abstract
Glycogen synthase kinase (GSK)-3β plays a key role in the phosphorylation and regulation of metabolic enzymes and many transcription factors. Recent studies have suggested the involvement of GSK-3β in the pathogenesis and treatment target of DA-associated neuropsychiatric disorders, which has led to consider GSK-beta as one of the candidate genes for those disorders. GSK-3β genes are likely to be involved in mechanisms underlying attention deficit hyperactivity disorder (ADHD). We investigated the association between -1727A/T and -50T/C SNPs of GSK-3β gene with ADHD. All ADHD subjects completed a comprehensive and standardized diagnostic test and psychological evaluation battery, including the parents' Korean version of the ADHD Rating Scale-IV (ARS). The genotype and allele frequencies of 103 ADHD patients and 173 normal controls were analyzed for -1727A/T and -50T/C SNPs of GSK-3β gene. There were statistically significant differences in the genotype distributions of the -1727A/T SNP of GSK-3β gene between the ADHD group and the control group. The frequency of the genotype AT was significantly higher in the ADHD patients. Concerning the haplotype, there was a significant difference in the A-C haplotype frequency between the two samples. However, no differences in either the genotype distribution or in allele frequencies of -50C/T were observed between the two samples. In the parents version of K-ARS of all subjects, ANCOVA revealed that two subscales and the total score were significantly higher in the subjects with AT+TT genotypes than those with AA genotype after adjusting for age and gender. The odds ratio for the ADHD patients was 1.79, comparing the AT genotype group with the AA genotype group. Therefore, genotype AT is associated with a higher risk of ADHD. Our results suggest that the -1727A/T SNP of GSK-3β gene may affect susceptibility in ADHD. Further investigation with a larger number of subjects is needed to validate this finding.

Abstract
Current gold standard in the treatment of depression includes pharmacotherapeutic and psychotherapeutic strategies together with social support. Due to the actually discussed controversies concerning the differential efficacy of antidepressants, a contribution to a comprehensive clarification seems to be necessary to avert further deterioration and uncertainty from patients, relatives, and their treating psychiatrists and general practitioners. Both efficacy and clinical effectiveness of antidepressants in the treatment of depressive disorders can be confirmed. Clinically meaningful antidepressant treatment effects were confirmed in different types of studies. Methodological issues of randomized controlled studies, meta-analyses, and effectiveness studies will be discussed. Furthermore, actual data about the differential efficacy and effectiveness of antidepressants with distinct pharmacodynamic properties and about outcome differences in studies using antidepressants and/or psychotherapy are discussed. This is followed by a clinically oriented depiction-the differential clinical effectiveness of different pharmacodynamic modes of action of antidepressants in different subtypes of depressive disorders. It can be summarized that the spectrum of different antidepressant treatments has broadened during the last decades. The efficacy and clinical effectiveness of antidepressants is statistically significant and clinically relevant and proven repeatedly. For further optimizing antidepressant treatment plans, clearly structured treatment algorithms and the implementation of psychotherapy seem to be useful. A modern individualized antidepressant treatment in most cases is a well-tolerated and efficacious tool to minimize the negative impact of the otherwise devastating and life-threatening outcome of depressive disorders.

Abstract
Current gold standard approaches to the treatment of depression include pharmacotherapeutic and psychotherapeutic interventions with social support. Due to current controversies concerning the efficacy of antidepressants in randomized controlled trials, the generalizability of study findings to wider clinical practice and the increasing importance of socioeconomic considerations, it seems timely to address the uncertainty of concerned patients and relatives, and their treating psychiatrists and general practitioners. We therefore discuss both the efficacy and clinical effectiveness of antidepressants in the treatment of depressive disorders. We explain and clarify useful measures for assessing clinically meaningful antidepressant treatment effects and the types of studies that are useful for addressing uncertainties. This includes considerations of methodological issues in randomized controlled studies, meta-analyses, and effectiveness studies. Furthermore, we summarize the differential efficacy and effectiveness of antidepressants with distinct pharmacodynamic properties, and differences between studies using antidepressants and/or psychotherapy. We also address the differential effectiveness of antidepressant drugs with differing modes of action and in varying subtypes of depressive disorder. After highlighting the clinical usefulness of treatment algorithms and the divergent biological, psychological, and clinical efforts to predict the effectiveness of antidepressant treatments, we conclude that the spectrum of different antidepressant treatments has broadened over the last few decades. The efficacy and clinical effectiveness of antidepressants is statistically significant, clinically relevant, and proven repeatedly. Further optimization of treatment can be helped by clearly structured treatment algorithms and the implementation of psychotherapeutic interventions. Modern individualized antidepressant treatment is in most cases a well-tolerated and efficacious approach to minimize the negative impact of otherwise potentially devastating and life-threatening outcomes in depressive disorders.

Abstract
Unipolar depressive disorders are among the most frequent reasons for utilizing the health care system. Although efficacious treatments are available and further advances have recently been made there is still a need for improving diagnostic and therapeutic procedures. Alignment of treatment on evidence-based treatment guidelines establishes an essential mainstay. The new S3 and National Health Care guidelines on unipolar depression, the compilation of which was coordinated by the German Society of Psychiatry, Psychotherapy and Neurology (DGPPN) and which were approved by 29 scientific and professional associations, is the ambitious effort to present state of the art evidence and clinical consensus for the treatment of depression. For pharmacotherapy of depression differentiated recommendations can be given, also separate from and in addition to psychotherapy.

Abstract
Bipolar disorder (BD) is a chronic and often severe psychiatric illness characterized by manic and depressive episodes. Among the most effective treatments, mood stabilizers represent the keystone in acute mania, depression, and maintenance treatment of BD. However, treatment response is a highly heterogeneous trait, thus emphasizing the need for a structured informational framework of phenotypic and genetic predictors. In this paper, we present the current state of pharmacogenomic research on long-term treatment in BD, specifically focusing on mood stabilizers. While the results provided so far support the key role of genetic factors in modulating the response phenotype, strong evidence for genetic predictors is still lacking. In order to facilitate implementation of pharmacogenomics into clinical settings (i.e., the creation of personalized therapy), further research efforts are needed.

Abstract
BACKGROUND Glycogen synthase kinase (GSK)-3beta plays a key role in the phosphorylation and regulation of metabolic enzymes and many transcription factors. Several lines of evidence implicate GSK-3beta in the pathophysiology of mood disorders and susceptibility to suicidal behavior. In this study, we aimed to investigate the GSK-3beta gene's association with major depressive disorder (MDD) and suicidal behavior. METHODS One hundred seventy suicidal depressed patients and 147 non-suicidal depressed patients who met DSM-IV criteria for MDD were recruited. One hundred sixty-four healthy volunteers recruited by local advertisement served as controls. Patients and normal controls were genotyped for GSK-3beta -1727A/T and -50C/T. Haplotype trend regression (HTR) analysis was used for the evaluation of haplotype association. RESULTS The genotype distributions of -1727A/T and -50C/T were in agreement with Hardy-Weinberg equilibrium. The results showed that the alleles, genotypes, and haplotypes of the two SNPs do not differ between suicidal MDD subjects, non-suicidal MDD subjects, and normal controls. There was no difference in the haplotype frequency combination between the three groups. CONCLUSION Our study suggests that two promoter polymorphisms of the GSK-3beta gene may not be related to the pathogenesis of MDD and the risk of suicidal behavior in Korean depressive patients. Further studies with larger sample sizes and different populations are needed.

Abstract
BACKGROUND The purpose of the present open-label study was to investigate the antidepressant efficacy of lithium and carbamazepine as augmentation strategies in unipolar depressed inpatients. METHOD Forty-six patients suffering from unipolar depression (major depressive episode according to DSM-IV criteria) were pre-treated with mirtazapine for 2 weeks initially (week -2 to week 0). Thereafter, the patients received either continuation of mirtazapine monotherapy (n = 23), combination treatment with mirtazapine and lithium (n = 13), or combination therapy with mirtazapine and carbamazepine (n = 10) for further 3 weeks (week 0 to week 3). Severity of depression was estimated weekly using the 21-item version of the Hamilton Depression Rating Scale (21-HAMD). Response was defined by a reduction of at least 50% in the 21-HAMD sum score after 3 weeks of pharmacotherapy (week 0-3). RESULTS Additional administration of lithium, but not adjunctive carbamazepine significantly augmented the antidepressant efficacy of mirtazapine in the unipolar depressed patients. Moreover, carbamazepine but not lithium significantly lowered the serum concentrations of mirtazapine. CONCLUSION Whereas the clinical importance of anticonvulsants in the treatment of bipolar disorder is not in doubt, the therapeutic efficacy of antiepileptic drugs such as carbamazepine is obviously limited in the pharmacotherapy of unipolar depression.

Abstract
Lithium, a drug commonly used to treat mood disorders, and the psychostimulant methamphetamine are both capable of altering circadian rhythmicity. Although the actions of lithium on the circadian system are thought to occur through inhibition of glycogen synthase kinase-3beta (GSK3beta), the mechanism by which methamphetamine alters circadian rhythms is unknown. We tested the effects of concurrent methamphetamine and lithium treatment on the circadian wheel-running behavior of mice. Methamphetamine alone lengthened both the active duration and the free-running period of locomotor activity in animals housed in constant conditions. Administering lithium enhanced the period-lengthening effects of methamphetamine in animals housed in constant darkness. This effect was even more pronounced when animals were housed in constant light. Lithium increased both methamphetamine intake and serum levels of methamphetamine, possibly contributing to the effects on circadian behavior. We also tested the effect of methamphetamine in mutant mice possessing only one allele for Gsk3beta. These animals, when treated with methamphetamine, responded like wild-type mice treated with a combination of methamphetamine and lithium, displaying long, free-running rhythms. These data, together with many others in the literature, point to a complicated interaction between the circadian system and the development and possible treatment of psychopathologies such as bipolar disorder and drug addiction.

Abstract
Major depressive disorder (MDD) is an often chronic, recurrent illness affecting large numbers of the general population. In recent years, the goal of treatment for MDD has moved from mere symptomatic response to that of full remission (i.e., minimal/no residual symptoms). The recent Sequenced Treatment Alternatives to Relieve Depression (STAR*D) trial showed that even with systematic measurement-based treatment, approximately one third of patients reach full remission after one treatment trial, with only two thirds reaching remission after four treatment trials. Treatment-resistant depression (TRD) is therefore a common problem in the treatment of MDD, with 60% to 70% of all patients meeting the criteria for TRD. Given the huge burden of major depressive illness, the low rate of full recovery remains suboptimal. The following article reports on some current treatment strategies available to improve rates of, and to sustain, remission in MDD.

Abstract
Core symptoms of depression are a combination of psychological and somatic symptoms, often combined with psychomotor and cognitive disturbances. Diagnostic classification of depression including the concepts of melancholic, endogenous, or severe depression describe severely depressed patients suffering from most of the core symptoms, together with clinical characteristics of a cyclic unipolar or bipolar course, lower placebo response rates, higher response rates to electroconvulsive therapy, to antidepressant treatments with dually or mixed modes of action, or to lithium augmentation. Higher rates ofhypothalamic-pituitary-adrenal axis hyperactivity and specific electroencephalograph patterns have also been shown in this patient group. Summarizing the symptomatology of depression in these patients, a broad overlap between the abovementioned subgroups can be suggested. Because the positive diagnosis of those core symptoms of depression may include clinical consequences, it would be of use to integrate all the mentioned concepts in the upcoming new versions of the diagnostic systems DSM-V and ICD-11.

Abstract
In contemporary psychiatry, depression and mania are conceived as different entities. They may occur together, as in bipolar disorder, or they may occur separately, as in unipolar depression. This view is partly based on a narrow definition of mania and a rather broad definition of depression. Generally, depression is seen as more prominent, common, and problematic; while mania appears uncommon and treatment-responsive. We suggest a reversal: mania viewed broadly, not as simply episodic euphoria plus hyperactivity, but a wide range of excitatory behaviors; and depression seen more narrowly. Further, using pharmacological and clinical evidence, and in contrast to previous theories of mania interpreted as a flight from depression, we propose the primacy of mania hypothesis (PM): depression is a consequence of the excitatory processes of mania. If correct, current treatment of depressive illness needs revision. Rather than directly lifting mood with antidepressants, the aim would be to suppress manic-like excitation, with depression being secondarily prevented. Potential objections to, and empirical tests of, the PM hypothesis are discussed.

Abstract
BACKGROUND Patients with major depression refractory to repeated pharmacological trials (TRD) may remain symptomatic for many years after their index episode. Augmentation strategies (with lithium or an atypical antipsychotic) or combining an antidepressant with short-term psychotherapy have been used with relative success in these patients. The aim of this study was to assess the effectiveness of the concomitant administration of quetiapine, an atypical antipsychotic, or placebo, to cognitive-behavior therapy (CBT) in TRD. METHODS Thirty-one patients who met entrance criteria for unipolar major depression (TRD stage II or greater) underwent 3 weeks of lithium augmentation after which non-responders (N = 22) were randomized to receive either quetiapine or placebo as an adjunct to their 12 weekly CBT sessions (quetiapine/CBT or placebo/CBT groups). Primary efficacy measures were the Hamilton and the Montgomery-Asberg rating scales for depression. RESULTS Overall, there was a significant reduction in both primary efficacy measure scores at LOCF for the 11 patients in the quetiapine/CBT group but not in the placebo/CBT treated patients. Patients in the quetiapine/CBT group, compared to those receiving placebo/CBT, showed a significantly greater degree of improvement on one primary and one secondary efficacy measure, were more likely to complete the trial and, completed a greater number of CBT sessions. CONCLUSION Although preliminary, our results suggest that the adjunctive administration of quetiapine to CBT may prove useful in the treatment of stage II TRD.

Intravenous augmentative citalopram versus clomipramine in partial/nonresponder depressed patients: a short-term, low dose, randomized, placebo-controlled study.

Abstract
The aim of the present study was to evaluate the efficacy of short-term low-dose intravenous augmentative citalopram (10 mg/d) versus clomipramine (25 mg/d) versus placebo in a sample of patients with MDE and partial or no response to selective serotonin reuptake inhibitors (SSRIs). Fifty-four patients with a Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision, MDE and partial or no response to SSRIs per os (21-item Hamilton Depression Rating Scale [HAM-D21] score reduction, <50% or < or =25%, respectively, compared with pretreatment scores) were selected and randomized to citalopram (n = 18), clomipramine (n = 18), or placebo (n = 18) intravenous augmentation. The augmentation regimen lasted 5 days during which patients were maintained on their previous treatment with oral SSRIs. Analyses of variance with repeated measures on HAM-D(21), collected daily in blind-raters design, were performed to detect any change of depressive symptoms between the 3 groups. In addition, the number of responders and remitters was computed in the 3 groups of treatment. At end point, a significant treatment effect (F= 4.57; P = 0.015) and time-by-treatment effect (F = 11.22; P < 0.0001) were found on HAM-D21 total scores in favor of citalopram and clomipramine versus placebo, with a superiority of citalopram over clomipramine on overall symptoms (P = 0.05) as well as on anxiety-somatization symptoms (P = 0.027). The number of responders was significantly superior in the active treatment groups versus the placebo group ([chi](2)(2) = 16.36; P < 0.0001). The same result was found, considering the number of remitters ([chi](2)(2) = 13.50; P < 0.0001). Present findings suggest that both clomipramine and citalopram intravenous augmentation at low doses and for a short period are well tolerated and superior to placebo in major depressives with partial or no response to oral SSRIs with a possible superiority of citalopram over clomipramine with regard to anxiety-somatization symptoms. The lack of double-blind conditions and the limited sample size may limit the confidence in the reported results, and larger randomized controlled trials are warranted to confirm the present findings.

Abstract
Approximately 30-45% of patients with major depressive episode (MDE) do not fully respond to standard recommended treatments and further strategies of intervention, including pharmacological augmentation, have been proposed for these patients. This study was aimed to evaluate the efficacy of short-term, low-dose (10 mg/day) intravenous (i.v.) citalopram augmentation versus placebo in a sample of patients with MDE and partial or no response to selective serotonin reuptake inhibitors (SSRIs). Thirty-six patients with a Diagnostic and Statistical Manual for Mental Disorders, 4th edition, text revision criteria MDE and partial or no response to oral SSRIs were selected and randomly assigned to citalopram (n=18) or to placebo (n=18) i.v. augmentation. The augmentation regimen lasted 5 consecutive days during which the patients were maintained on their current treatment with oral SSRIs. Analyses of variance with repeated measures on Hamilton Depression Rating Scale and Montgomery-Asberg Depression Rating Scale total scores, administered daily with blind-raters conditions, were done. With regard to the Hamilton Depression Rating Scale total scores, a significant time effect (F=42.02, P<0.0001) and timextreatment effect (F=21.17, P<0.0001) were found in favor of citalopram. Similar results were obtained from the analysis on Montgomery-Asberg Depression Rating Scale total scores: time effect (F=50.07, P<0.0001), timextreatment effect (F=19.91, P<0.0001), and treatment effect (F=4.07, P=0.05). Even though referred to a small sample, the present findings seem to suggest that short-term, low-dose, i.v. citalopram augmentation may be effective in depressed patients with partial or no response to oral SSRIs. Further controlled studies performed with double-blind conditions are warranted to confirm the present results.

Abstract
BACKGROUND Glycogen synthase kinase 3-beta (GSK3B) is a serine/threonine kinase which is directly inhibited by lithium. A -50T/C single nucleotide polymorphism (SNP) localized within the promoter region of the GSK3B gene has previously been shown to be associated with response to lithium prophylaxis in bipolar disorder. This study investigates the association of the GSK3B -50T/C SNP and response to lithium augmentation in acutely depressed antidepressant nonresponders. METHODS Eighty-one patients who had not responded to at least one adequate trial of antidepressant monotherapy underwent a standardized trial of lithium augmentation for up to 8 weeks. We genotyped for the GSK3B -50T/C SNP using polymerase chain reaction and restriction fragment length polymorphism methods and investigated the association with remission. RESULTS The allele frequencies in our sample were CC 14.8%, CT 48.2% and TT 37% (no deviation from the Hardy-Weinberg equilibrium). Carriers of the C-allele of the -50T/C SNP showed a significantly better response to lithium augmentation (hazard ratio: 2.70, p = .007), with a mean remission rate of 56.25% after 4 weeks compared to 31% in patients with the TT-genotype (chi(2) = 4.1; p = .04). CONCLUSIONS Our results support the finding of recent studies demonstrating a superior response of C-allele carriers with bipolar disorder to lithium prophylaxis.

Abstract
In 1845 Griesinger declared that mental disorders were physical in origin (Kendell, 2001). The discovery of the bacterial cause of general paresis and the anatomical basis for Alzheimer's disease seemed to confirm this belief. However, is it still reasonable, a century later, to continue to devote increasing amounts of financial and expert human resource to pursuing further possible physical causes for mental disorders? The belief that there remain undiscovered and important biological causes for mental disorders continues to exert a major influence on the direction of research, practice and public education. But has it helped us to understand aetiology, improve management or destigmatise mental disorders?

Abstract
The efficacy of the addition of lithium to an established course of antidepressant treatment can be explained by a synergistic effect of the two drugs on central 5-HT neurotransmission. In the present study we investigated the effect of lithium addition on the 5-HT concentration in plasma and platelets and the concentration of 5-HIAA. Thirty-nine depressed inpatients who fulfilled the DSM-IV criteria for major depressive disorder and who did not respond to monotherapy with either imipramine or fluvoxamine participated in this study. Concentration of 5-HT in both plasma and platelets did not change significantly during lithium addition. The 5-HT ratio (plasma concentration/platelet concentration) shows a small non-significant increase after 3 weeks lithium addition. The mean concentration of 5-HIAA shows a significant increase during lithium addition; with no difference between the imipramine and the fluvoxamine sample. The increments in 5-HIAA concentration during lithium addition are indicative of an increased 5-HT turnover.

Abstract
Bipolar disorder is a serious psychiatric condition that has been treated for over 50 years with lithium. Lithium is a well established glycogen synthase kinase-3 (GSK-3) inhibitor, suggesting that manipulating GSK-3 may have therapeutic value in treating bipolar disorder. GSK-3 is regulated by a wide variety of mechanisms including phosphorylation, binding with protein complexes, phosphorylation state of its substrates, cellular localization and autoregulation, thus providing a wide number of potential therapeutic mechanisms. Mounting evidence suggests that GSK-3 regulation can be used to manage bipolar disorder symptoms. Although GSK-3 mutations have not been detected amongst the general bipolar population, they have been correlated with females with bipolar II and most of the drugs used for successful bipolar disorder treatment regulate GSK-3. These drugs produce a weak anti-depressant-like and a strong anti-mania-like effect in a wide range of animal models tested, mirroring their utility in treating bipolar disorder symptoms. Taken together, the evidence suggests that targeting GSK-3 may be a means to control the symptoms of bipolar disorder.

Abstract
BACKGROUND Two promising approaches have been introduced for the prediction of treatment response in major depression: one concept is based on the activity in the rostral anterior cingulate cortex (rACC). Subjects with higher metabolic rates respond better to sleep deprivation or antidepressive medication. Another approach is the investigation of the loudness dependence of the auditory evoked potential (LDAEP). Here, a high LDAEP is supposed to reflect low central serotonergic activity. We present the first study comparing both approaches in the same group of patients. METHODS Patients with major depression (n=20) were investigated using both resting EEG and LDAEP before treatment with either citalopram or reboxetine. RESULTS We found significant differences between responders and non-responders in the rACC in the theta-frequency range (6.5-8 Hz, p<0.05). In the subgroup of patients, treated with citalopram we found higher LDAEP-values in responders versus non-responders (p<0.05) and a significant correlation between pre-treatment-LDAEP and improvement in the Hamilton score after treatment (r=0.71, p<0.05). CONCLUSIONS In combining both methods a prediction whether a patient with major depression might be at risk for non-response to a standard therapy as well as a suggestion for a pharmacological approach of choice seems to be possible.

Abstract
Patients with bipolar disorder are at very high risk for suicidal ideation, non-fatal suicidal behaviors and suicide and are frequently treated with antidepressants. However, no prospective, randomized, controlled study specifically evaluating an antidepressant on suicidality in bipolar disorder has yet been completed. Indeed, antidepressants have not yet been shown to reduce suicide attempts or suicide in depressive disorders and may increase suicidal behavior in pediatric, and possibly adult, major depressive disorder. Available data on the effects of antidepressants on suicidality in bipolar disorder are mixed. Considerable research indicates that mixed states are associated with suicidality and that antidepressants, especially when administered as monotherapy, are associated with both suicidality and manic conversion. In contrast, growing research suggests that antidepressants administered in combination with mood stabilizers may reduce depressive symptoms in patients with bipolar depression. Further, the only prospective, long-term study evaluating antidepressant treatment and mortality in bipolar disorder, although open-label, found antidepressants and/or antipsychotics in combination with lithium, but not lithium alone, reduced suicide in bipolar and unipolar patients (Angst F, et al. J Affect Disord 2002: 68: 167-181). We conclude that antidepressants may induce suicidality in a subset of persons with depressive (and probably anxious) presentations; that this induction may represent a form of manic conversion, and hence a bipolar phenotype, and that lithium's therapeutic properties may include the ability to prevent antidepressant-induced suicidality.

Abstract
Treatment-resistant depression represents a common problem, with the vast majority of depressed patients showing incomplete response to antidepressant trials. Augmentation and combination strategies are commonly employed to address this problem, but there are few randomized, controlled studies to guide treatment choice. Indeed, some of the most common augmentation strategies in depression are those with the least controlled evidence. The popularity of bupropion, psychostimulants and atypical antipsychotics as augmentors may not be warranted by existing controlled studies, whereas two less commonly used augmentors-lithium and thyroid hormone- have substantial controlled evidence to support their use. This paper summarizes the state of the evidence for commonly used augmenting strategies and explores preliminary findings for more investigational approaches.

Abstract
OBJECTIVE The aim of this paper was to review the rationales, risks, and benefits for using standard antidepressants versus mood stabilizing agents and/or atypical antipsychotics to treat bipolar depression. METHOD A selective literature review was conducted using key terms and by reference known to the authors. Bibliographies of articles and book chapters were further scrutinized for relevant literature. RESULTS The strengths and limitations of current studies are described and critically reviewed in order to present optimal strategies for effective pharmacotherapy. Clinical factors that can mitigate or confound simple bivariate relationships between antidepressant use and outcome have seldom been examined using multivariate statistical techniques. For many of the key questions there is a paucity of informative literature and randomized clinical trials are of limited value in addressing some of the issues. CONCLUSIONS Clinicians and investigators should be aware of the methodological shortcomings of existing studies. Decisions about the relative merits versus contraindications for antidepressant use should be made via more individualized, case-by-case profiling rather than by rigid prescribing practices.

Abstract
Most patients in acute depression trials fail to achieve remission with antidepressant monotherapy. Many patients seem to require more than one medication to achieve remission or adequate response. Augmentation strategies are commonly used in clinical practice, but most have been poorly studied. In addition, better-studied strategies, such as the use of lithium and thyroid augmentation, have not been well investigated in combination with newer antidepressants. Various novel strategies are being investigated as augmenting agents, including selective dopamine agonists, sex steroids, norepinephrine reuptake inhibitors, glucocorticoid-specific agents, and newer anticonvulsants. We review the status of augmentation strategies in the treatment of depression.

Abstract
Treatment-resistant depression (TRD) represents a significant challenge for physicians. About one third of patients with major depressive disorder fail to experience sufficient symptom improvement despite adequate treatment. Despite this high occurrence of TRD there was no general consensus on diagnosis criteria for TRD until 1997 when researchers proposed a model of defining and staging TRD. In 1999, others defined operational criteria for the definition of TRD. Treatment of TRD is commonly separated into pharmacologic and nonpharmacologic methods. This review gives a short overview of these two methods. The nonpharmacologic methods include psychotherapy, electroconvulsive therapy, and vagus nerve stimulation. Pharmacologic methods include switching to another antidepressant monotherapy, and augmentation or combination with two or more antidepressants or other agents. This review especially focuses on the augmentation of the antidepressant therapy with atypical antipsychotics.

Abstract
Anxiety disorders are among the most prevalent psychiatric disorders in the general population, found nearly twice as often in women, and estimated to affect 26.9 million individuals in the United States alone. Anxiety disorders are associated with considerable chronicity, morbidity, and disability. Treatment of anxiety disorders includes pharmacologic and nonpharmacologic approaches. The first-line pharmacologic treatments currently include the use of serotonin reuptake inhibitors and selective serotonin reuptake inhibitors. However, despite the general success of the available treatments, no single anxiolytic appears to be effective for all patients suffering from anxiety. Low recovery rates have been reported in all anxiety disorders, underscoring the need for optimizing treatment for these disabling disorders. In recent years, there is increasing interest in the use of atypical neuroleptics in the treatment of anxiety disorders patients. This article discusses the emerging data on the use of these agents in the treatment of anxiety with a focus on treatment-refractory patients and on the implications for the treatment of women suffering from anxiety disorders.
