The Texas Children's Medication Algorithm Project: report of the Texas Consensus Conference Panel on Medication Treatment of Childhood Major Depressive Disorder

OBJECTIVES: To develop consensus guidelines for medication treatment algorithms for childhood major depressive disorder (MDD) based on scientific evidence and clinical opinion when science is lacking. The ultimate goal of this approach is to synthesize research and clinical experience for the practitioner and to increase the uniformity of preferred treatment for childhood MDD. A final goal is to develop an approach that can be tested as to whether it improves clinical outcomes for children and adolescents with MDD. METHOD: A consensus conference was held. Participants included academic clinicians and researchers, practicing clinicians, administrators, consumers, and families. The focus was to review and use clinical evidence to recommend specific pharmacological approaches for treatment of MDD in children and adolescents. After a series of presentations of current research evidence and panel discussion, the consensus panel met, agreed on assumptions, and drafted the algorithms. The process initially addressed strategies of treatment and then tactics to implement the strategies. RESULTS: Consensually agreed-upon algorithms for major depressions (with and without psychosis) and comorbid attention deficit disorders were developed. Treatment strategies emphasized the use of selective serotonin reuptake inhibitors. The algorithm consists of systematic strategies for treatment interventions and recommended tactics for implementation of the strategies, including medication augmentation and medication combinations. Participants recommended prospective evaluation of the algorithms in various public sector settings, and many volunteered as sites for such an evaluation. CONCLUSIONS: Using scientific and clinical experience, consensus-derived algorithms for children and adolescents with MDD can be developed.     

The Texas Medication Algorithm Project: report of the Texas Consensus Conference Panel on Medication Treatment of Major Depressive Disorder

BACKGROUND: This article describes the development of consensus medication algorithms for the treatment of patients with major depressive disorder in the Texas public mental health system. To the best of our knowledge, the Texas Medication Algorithm Project (TMAP) is the first attempt to develop and prospectively evaluate consensus-based medication algorithms for the treatment of individuals with severe and persistent mental illnesses. The goals of the algorithm project are to increase the consistency of appropriate treatment of major depressive disorder and to improve clinical outcomes of patients with the disorder. METHOD: A consensus conference composed of academic clinicians and researchers, practicing clinicians, administrators, consumers, and families was convened to develop evidence-based consensus algorithms for the pharmacotherapy of major depressive disorder in the Texas mental health system. After a series of presentations and panel discussions, the consensus panel met and drafted the algorithms. RESULTS: The panel consensually agreed on algorithms developed for both nonpsychotic and psychotic depression. The algorithms consist of systematic strategies to define appropriate treatment interventions and tactics to assure optimal implementation of the strategies. Subsequent to the consensus process, the algorithms were further modified and expanded iteratively to facilitate implementation on a local basis. CONCLUSION: These algorithms serve as the initial foundation for the development and implementation of medication treatment algorithms for patients treated in public mental health systems. Specific issues related to adaptation, implementation, feasibility testing, and evaluation of outcomes with the pharmacotherapeutic algorithms will be described in future articles.     

The effectiveness of atypical antipsychotic medications in depressive disorders

Clinical evidence supporting the use of atypical antipsychotic medication (broad-spectrum psychotropic agents) in the treatment of depressive disorders is increasing rapidly. Animal models suggest that when atypical antipsychotic medications are used in combination with a selective serotonin reuptake inhibitor there is additional activation of frontal dopaminergic and noradrenergic neurotransmitter systems. This stimulated the initiation of several clinical trials that showed the efficacy of atypical antipsychotic medication augmentation of selective serotonin reuptake inhibitors for patients with treatment-resistant depression. There also are few case reports of successful treatment of depression with atypical antipsychotic medication alone. When a clinician is treating a depressed patient who did not achieve relief after trials with two different antidepressant regimens, one option to consider is augmentation with an atypical antipsychotic medication to ameliorate depressive symptoms.     

Obsessive compulsive disorder, depression, and fluoxetine

BACKGROUND: Fluoxetine, a selective serotonin reuptake blocker, is an antidepressant medication that has also been shown in open clinical trials and one controlled trial to be effective in the treatment of obsessive compulsive disorder (OCD). OCD is often complicated by depression, and depressive symptoms may interfere with response to both pharmacologic and behavioral treatments. METHOD: We describe pilot data from 10 outpatients who met DSM-III-R criteria for OCD in whom the possibility of a depressive reaction or lack of antidepressant response occurred during an open trial of fluoxetine. RESULTS: Rapid increase in fluoxetine dose to high doses was associated with depressive symptoms in 6 patients. In 8 patients, improvement in depression was associated with addition of a tricyclic antidepressant to fluoxetine treatment. In 5 patients, both OCD and depressive symptoms improved when the patient was switched to the partially selective serotonin reuptake blocker clomipramine. CONCLUSION: This paper serves to alert clinicians to the possibility of a depressive reaction, or lack of antidepressant response, to fluoxetine in OCD patients. This possibility can only be resolved scientifically by adequately controlled experimental trials. If depression occurs, combined fluoxetine and tricyclic treatment, or a switch to a partially selective serotonin reuptake inhibitor, may be helpful. Special considerations and side effects of combined fluoxetine-tricyclic treatment are described.     

Use of selective serotonin reuptake inhibitors and youth suicide: making sense from a confusing story

PURPOSE OF REVIEW: This review provides an update on use of selective serotonin reuptake inhibitors and youth suicide, and describes an informed examination of the social and professional dimensions of this issue. RECENT FINDINGS: Recent studies, using various methodologies to analyze experimental and observational data, suggest that concerns about the effect of selective serotonin reuptake inhibitors on suicide and suicide-related phenomena may have been overstated. Also, contrary to much public and medical opinion, treatment of depression with selective serotonin reuptake inhibitors does not increase but rather may decrease youth suicide fatalities. A recent reanalysis by the US Food and Drug Administration of existing data from clinical trials across the lifespan suggest an age-dependent effect on nonfatal suicide attempts and suicidal ideation, in which risk appears to be increased in youth and reduced from mid-adulthood and onward. SUMMARY: Selective serotonin reuptake inhibitors are a modestly effective and generally safe treatment for postpubertal major depressive disorder, but their use requires collaborative decision making and a predetermined, shared monitoring plan.     

Report of the Texas Consensus Conference Panel on medication treatment of bipolar disorder 2000

BACKGROUND: The process and outcome of a consensus conference to develop revised algorithms for treatment of bipolar disorder to be implemented in the public mental health system of Texas are described. These medication algorithms for bipolar disorder are an update of those developed for the Texas Medication Algorithm Project, a research study that tested the clinical and economic impact of treatment guidelines for major psychiatric illnesses treated in the Texas public mental health system (Texas Department of Mental Health and Mental Retardation [TDMHMR]). METHOD: Academic clinicians and researchers, practicing clinicians in the TDMHMR system, administrators, advocates, and consumers participated in a consensus conference in August 2000. Participants attended presentations reviewing new evidence in the pharmacologic treatment of bipolar disorder and discussed the needs of consumers in the TDMHMR system. Principles were enumerated, including balancing of evidence for efficacy, tolerability, and safety in medication choices. A set of 7 distinct algorithms was drafted. In the following months, a subcommittee condensed this product into 2 primary algorithms. RESULTS: The panel agreed to 2 primary algorithms: treatment of mania/hypomania, including 3 pathways for treatment of euphoric symptoms, mixed or dysphoric symptoms, and psychotic symptoms; and treatment of depressive symptoms. General principles to guide algorithm implementation were discussed and drafted. CONCLUSION: The revised algorithms are currently being disseminated and implemented within the Texas public mental health system. The goals of the Texas initiative include increasing the consistency of appropriate treatment of bipolar disorder, encouraging systematic and optimal use of available pharmacotherapies, and improving the outcomes of patients with bipolar disorder.     

Pharmacotherapy in depressed children and adolescents

In children and adolescents, antidepressants are used in the treatment of depressive symptoms and several other psychiatric conditions. In the treatment of mild and moderate depressive symptoms, non-pharmacological approaches such as psychotherapy play a major role, a severe symptomatology may demand a combination with antidepressants. As first-choice medication for the treatment of juvenile depression, the selective serotonin reuptake inhibitor (SSRI) fluoxetine is recommended, due to its efficacy and approval. As second-choice antidepressants the SSRIs sertraline, escitalopram and citalopram might be used. Other antidepressants - such as tricyclic antidepressants, α(2)-adrenoceptor antagonists, selective noradrenalin reuptake inhibitors (SNRI) - may be alternatively used, but not as first- or second-choice medications. In the case of "off-label" use, patients and parents have to be carefully informed prior to the start of medication, after a thorough risk-benefit analysis. In the following overview we address a general framework, therapeutic strategies and the issues of antidepressant pharmacotherapy for the treatment of unipolar depression in childhood and adolescence.     

Pharmacotherapy for late-life depression

The 2001 expert consensus guidelines for treating major depressive disorder (MDD) in geriatric patients recommended antidepressant treatment in combination with psychotherapy. Recent evidence continues to support the use of selective serotonin reuptake inhibitors and serotonin-norepinephrine reuptake inhibitors as first-line agents in the elderly, and although the transdermal monoamine oxidase inhibitor selegilene has shown promise in adult patients, it has not been studied in geriatric depression. Augmentation therapy with atypical antipsychotics or other agents may provide benefits for agitated, psychotic, or resistant MDD in the elderly. The few treatment studies that have been conducted in the geriatric population since the publication of the guidelines have had mixed results and high placebo response rates. More large controlled trials are needed.     

Medication treatment of bipolar disorder 2000: a summary of the expert consensus guidelines

The original Expert Consensus Guidelines on the Treatment of Bipolar Disorder were published in 1996. Since that time, a variety of new treatments for bipolar disorder have been reported; however, evidence for these treatments varies widely, with data especially limited regarding comparisons between treatments and how to sequence them. For this reason, a new survey of expert opinion was undertaken to bridge gaps between the research evidence and key clinical decisions. The results of this new survey, which was completed by 58 experts, are presented in The Expert Consensus Guideline Series: Medication Treatment of Bipolar Disorder 2000, which was published in April 2000 as a Postgraduate Medicine Special Report. In this article, the authors describe the methodology used in the survey and summarize the clinical recommendations given in the resulting guidelines. The expert panel reached consensus on many key strategies, including acute and preventive treatment of mania (euphoric, mixed, and dysphoric subtypes), depression, rapid cycling, and approaches to managing treatment resistance and comorbid psychiatric conditions. Use of a mood stabilizer is recommended in all phases of treatment. Divalproex (especially for mixed or dysphoric subtypes) and lithium are the primary mood stabilizers for both acute and preventive treatment of mania. If monotherapy with these agents fails, the next recommended intervention is to combine them. This combination of lithium and divalproex can then serve as the foundation to which other medications are added if needed. Carbamazepine is the leading alternative mood stabilizer for mania. The experts rated the other new anticonvulsants as second-line options (i.e., their use is recommended if lithium, divalproex, and carbamazepine fail or are contraindicated). For milder depression, a mood stabilizer, especially lithium, may be used as monotherapy. Divalproex and lamotrigine are other first-line choices. For more severe depression, the experts recommend combining a standard antidepressant with lithium or divalproex. Bupropion, selective serotonin reuptake inhibitors (SSRIs), and venlafaxine are preferred antidepressants. The antidepressants should usually be tapered 2-6 months after remission. Monotherapy with divalproex is recommended for the initial treatment of either depression or mania in rapid-cycling bipolar disorder. Antipsychotics are recommended for use in combination with the above regimens for mania or depression with psychosis, and as potential adjuncts in nonpsychotic episodes. Atypical antipsychotics, especially olanzapine and risperidone, were generally preferred over conventional antipsychotics. The guidelines also include recommendations concerning the use of electroconvulsive therapy (ECT), clozapine, thyroid hormone, stimulants, and various novel agents for patients with treatment-refractory bipolar illness. The experts reached high levels of consensus on key steps in treating bipolar disorder despite obvious gaps in high-quality data. To evaluate many of the treatment options in this survey, the experts had to extrapolate beyond controlled data; however, their recommendations are generally conservative. Experts give their strongest support to initial strategies and medications for which high-quality research data or longstanding patterns of clinical usage exist. Within the limits of expert opinion and with the understanding that new research data may take precedence, these guidelines provide clear pathways for addressing common clinical questions and can be used to inform clinicians and educate patients about the relative merits of a variety of interventions.     

The Texas Medication Algorithm Project antipsychotic algorithm for schizophrenia: 2003 update

BACKGROUND: The Texas Medication Algorithm Project (TMAP) has been a public-academic collaboration in which guidelines for medication treatment of schizophrenia, bipolar disorder, and major depressive disorder were used in selected public outpatient clinics in Texas. Subsequently, these algorithms were implemented throughout Texas and are being used in other states. Guidelines require updating when significant new evidence emerges; the antipsychotic algorithm for schizophrenia was last updated in 1999. This article reports the recommendations developed in 2002 and 2003 by a group of experts, clinicians, and administrators. METHOD: A conference in January 2002 began the update process. Before the conference, experts in the pharmacologic treatment of schizophrenia, clinicians, and administrators reviewed literature topics and prepared presentations. Topics included ziprasidone's inclusion in the algorithm, the number of antipsychotics tried before clozapine, and the role of first generation antipsychotics. Data were rated according to Agency for Healthcare Research and Quality criteria. After discussing the presentations, conference attendees arrived at consensus recommendations. Consideration of aripiprazole's inclusion was subsequently handled by electronic communications. RESULTS: The antipsychotic algorithm for schizophrenia was updated to include ziprasidone and aripiprazole among the first-line agents. Relative to the prior algorithm, the number of stages before clozapine was reduced. First generation antipsychotics were included but not as first-line choices. For patients refusing or not responding to clozapine and clozapine augmentation, preference was given to trying monotherapy with another antipsychotic before resorting to antipsychotic combinations. CONCLUSION: Consensus on algorithm revisions was achieved, but only further well-controlled research will answer many key questions about sequence and type of medication treatments of schizophrenia.     

The Texas Children's Medication Algorithm Project: Report of the Texas Consensus Conference Panel on Medication Treatment of Childhood Attention-Deficit/Hyperactivity Disorder. Part I. Attention-Deficit/Hyperactivity Disorder

OBJECTIVES: Expert consensus methodology was used to develop evidence-based, consensually agreed-upon medication treatment algorithms for attention-deficit/hyperactivity disorder (ADHD) in the public mental health sector. Although treatment algorithms for adult mental disorders have been developed, this represents one of the first attempts to develop similar algorithms for childhood mental disorders. Although these algorithms were developed initially for the public sector, the goals of this approach are to increase the uniformity of treatment and improve the clinical outcomes of children and adolescents with ADHD in a variety of treatment settings. METHOD: A consensus conference of academic clinicians and researchers, practicing clinicians, administrators, consumers, and families was convened to develop evidence-based consensus algorithms for the pharmacotherapy of childhood ADHD. After a series of presentations of current research evidence and panel discussion, the consensus panel met and drafted the algorithms along with guidelines for implementation. RESULTS: The panel developed consensually agreed-upon algorithms for ADHD with and without specific comorbid disorders. The algorithms consist of systematic strategies for psychopharmacological interventions and tactics to ensure successful implementation of the strategies. While the algorithms focused on the medication management of ADHD, the conference emphasized that psychosocial treatments are often a critical component of the overall management of ADHD. CONCLUSIONS: Medication algorithms for ADHD can be developed with consensus. A companion article will discuss the implementation of these algorithms.     

Medication treatment for the severely and persistently mentally ill: the Texas Medication Algorithm Project.

This article provides an overview of the issues involved in developing, using, and evaluating specific medication guidelines for patients with psychiatric disorders. The potential advantages and disadvantages, as well as the essential elements in the structure of algorithms, are illustrated by experience to date with the Texas Medication Algorithm Project, a public-academic collaboration. Phase 1 entailed assembling research findings on the efficacy of medications for schizophrenic, bipolar, and major depressive disorders. This knowledge was evaluated for its quality and relevance, integrated with expert clinical judgment as well as input by practicing clinicians, family advocates, and patients. Phase 1 (the design and development of the algorithms) was followed by a feasibility test (Phase 2). Phase 3 is an ongoing evaluation comparing the clinical and economic effects of using specific medication guidelines (algorithms) versus treatment as usual in public sector patients with severe and persistent mental illnesses.     

Treatment of depression in women: a summary of the expert consensus guidelines

Women constitute two-thirds of patients suffering from common depressive disorders, making the treatment of depression in women a substantial public health concern. However, high-quality, empirical data on depressive disorders specific to women are limited, and there are no comprehensive evidence-based practice guidelines on the best treatments for these illnesses. To bridge the gap between research evidence and key clinical decisions, the authors developed a survey of expert opinion concerning treatment of four depressive conditions specific to women: premenstrual dysphoric disorder, depression in pregnancy, postpartum depression in a mother choosing to breast-feed, and depression related to perimenopause/menopause. The survey asked about 858 treatment options in 117 clinical situations and included a broad range of pharmacological, psychosocial, and alternative medicine approaches. The survey was sent to 40 national experts on women's mental health issues, 36 (90%) of whom completed it. The options, scored using a modified version of the RAND Corporation's 9-point scale for rating appropriateness of medical decisions, were assigned one of three categorical rankings-first line/preferred choice, second line/alternate choice, third line/usually inappropriate-based on the 95% confidence interval of each item's mean rating. The expert panel reached consensus (defined as a non-random distribution of scores by chi-square "goodness-of-fit" test) on 76% of the options, with greater consensus in situations involving severe symptoms. Guideline tables indicating preferred treatment strategies were then developed for key clinical situations. The authors summarize the expert consensus methodology they used and then, for each of the four key areas, review the treatment literature and summarize the experts' recommendations and how they relate to the research findings. For women with severe symptoms in each area we asked about, the first-line recommendation was antidepressant medication combined with other modalities (generally psychotherapy). These recommendations parallel existing guidelines for severe depression in general populations. For initial treatment of milder symptoms in each situation, the panel was less uniform in recommending antidepressants, and either gave equal endorsement to other treatment modalities (e.g., nutritional or psychobehavioral approaches in PMDD; hormone replacement in perimenopause) or preferred psychotherapy over medication (during conception, pregnancy, or lactation). In all milder cases, however, antidepressants were recommended as at least second-line options. Among antidepressants, selective serotonin reuptake inhibitors (SSRIs) were recommended as first-line treatment in all situations. The specific SSRIs that were preferred depended on the particular clinical situation. Tricyclic antidepressants were highly rated alternatives to SSRIs in pregnancy and lactation. In evaluating many of the treatment options, the experts had to extrapolate beyond controlled data in comparing treatment options with each other or in combination. Within the limits of expert opinion and with the expectation that future research data will take precedence, these guidelines provide some direction for addressing common clinical dilemmas in women, and can be used to inform clinicians and educate patients regarding the relative merits of a variety of interventions.     

Serotonin and neuroplasticity – Links between molecular,functional and structural pathophysiology in depression

Serotonin modulates neuroplasticity, especially during early life, and dysfunctions in both systems likewise contribute to pathophysiology of depression. Recent findings demonstrate that serotonin reuptake inhibitors trigger reactivation of juvenile-like neuroplasticity. How these findings translate to clinical antidepressant treatment in major depressive disorder remains unclear. With this review, we link preclinical with clinical work on serotonin and neuroplasticity to bring two pathophysiologic models in clinical depression closer together. Dysfunctional developmental plasticity impacts on later-life cognitive and emotional functions, changes of synaptic serotonin levels and receptor levels are coupled with altered synaptic plasticity and neurogenesis. Structural magnetic resonance imaging in patients reveals disease-state-specific reductions of gray matter, a marker of neuroplasticity, and reversibility upon selective serotonin reuptake inhibitor treatment. Translational evidence from magnetic resonance imaging in animals support that reduced densities and sizes of neurons and reduced hippocampal volumes in depressive patients could be attributable to changes of serotonergic neuroplasticity. Since ketamine, physical exercise or learning enhance neuroplasticity, combinatory paradigms with selective serotonin reuptake inhibitors could enhance clinical treatment of depression.     

Major Depressive Disorder and HIV-1 Infection: A Review of Treatment Trials

Major depression is a common psychiatric presentation during the course of many chronic illnesses. Although estimates of its prevalence in people with human immunodeficiency virus (HIV) infection and acquired immunedeficiency syndrome have varied widely in the literature, it has become increasingly clear that people with HIV infection experience depression or depressive symptoms frequently, and that major depression may be the most common psychiatric disorder. This report reviewed the currently reported data and clinical trials for treatment of depression or depressive symptoms in the course of HIV infection. We have reviewed both psychopharmacologic and psychotherapy trials and although blinded efficacy studies are the gold standard, because there is often a lack of data, we have included noncontrolled (open) trials for comparison. Pharmacologic medication trials show that selective serotonin reuptake inhibitors (SSRIs), although not more efficacious, may be more tolerable and have greater overall effectiveness. Furthermore, when medications are used to treat depression, it may be essential to evaluate for tolerability and potential drug interactions to increase efficacy. Psychotherapy trials have investigated a variety of treatment modalities including group, individual, and stress reduction techniques. In treatment trials, all of these modalities have been associated with a reduction in distress and depressive symptoms. With the advances in therapy for HIV infection, treatment of a major depressive episode or depressive symptoms has become increasing important because untreated depression could both compromise medication adherence and potentiate the disabling effects of the illness.     

Duloxetine: review of its pharmacology, and therapeutic use in depression and other psychiatric disorders.

BACKGROUND: The discovery of antidepressant medications has revolutionized the treatment of depression and other psychiatric illnesses. The coming of the selective serotonin (5-HT) reuptake inhibitors (SSRIs) marked a new era in the treatment of depression. These therapies frequently fall short of getting the patient to remission. Agents with a dual action have subsequently been developed which inhibit the reuptake of both 5-HT and NE, getting more patients to remission. Physical symptoms are associated with depression, preventing the patient from obtaining complete recovery. This article provides an overview of the pharmacology, efficacy, and techniques for the clinical use of duloxetine, a dual reuptake inhibitor, which has recently become available. METHODS: The English literature has been reviewed including both controlled and uncontrolled studies. RESULTS: Duloxetine is a dual reuptake inhibitor with actions on serotonin as well as norepinephrine. It has been shown to have efficacy in treating depressive symptoms including those with painful physical symptoms. Common side effects include nausea, insomnia, and dizziness. CONCLUSIONS: The article has been written with clinicians as the target audience, the data suggesting it can be used as a first line agent.     

Duloxetine in the acute and continuation treatment of major depressive disorder

Duloxetine is a serotonin-noradrenaline reuptake inhibitor with indications for use in the short term, continuation and maintenance treatment of major depression. Although clinicians currently have access to a range of medications for the treatment of depression, a significant number of patients fail to respond or remit from their illness despite adequate trials of treatment with multiple agents. A developing concept is that antidepressant strategies that combine multiple mechanisms of action may have advantages over agents with single mechanisms (i.e., selective serotonin reuptake inhibitors). As a dual-acting agent, duloxetine offers the promise of advantages in terms of efficacy over selective serotonin reuptake inhibitors while retaining a favorable safety and tolerability profile in comparison to older agents. Likewise, duloxetine is of interest in the treatment of certain conditions commonly seen in conjunction with major depression, particularly anxiety and pain, both of which may respond more favorably to agents that act on both serotonin and noradrenaline neurotransmitter systems.     

Child and Adolescent Depression Intervention Overview: What Works,for Whom and How Well?

The authors review the currently available evidence-based treatments of child and adolescent major depressive disorder. Medication monotherapy, namely with selective serotonin reuptake inhibitors, is supported by large clinical trials in adolescents. For mild to moderate depression, cognitive behavior therapy (CBT) and interpersonal therapy are reasonable options as monotherapies. There is also evidence that the combination of medication and CBT is superior to medication alone for accelerating the pace of treatment response and remission, despite some negative studies. Response, remission, and recurrence rates after acute treatment and during long-term follow-ups are also presented and discussed.     

The Korean Medication Algorithm for Major Depressive Disorder (KMA-MDD): Report of the Korean Society of Depressive and Bipolar Disorders

Objective. There are many differences in biological characteristics, clinical situations, and medical insurance systems with ethnic groups or countries. The Korean Society of Depressive and Bipolar Disorders decided to develop a Korean treatment algorithm for major depressive disorder. Methods. The Korean Medication Algorithm Project for Major Depressive Disorder (KMAP-MDD) was designed with the following principles: (1) to be an ideal algorithm, (2) to be a Korean algorithm, (3) to be a medication algorithm, (4) to be an evidence-based and formal consensus algorithm. After collecting and reviewing many literature citations and reports by evidence-based rule, we constructed a survey questionnaire for formal consensus of Korean experts. By employing panels of experts to review the evidence and survey results thoroughly, we used evidence-based algorithm development as a component of a formal consensus development process. Results. We developed two algorithms for the KMA-MDD: one for major depressive disorder without psychotic feature and the other for major depressive disorder with psychotic features. Clinical guidelines for the implementation of KMA-MDD were also developed. The KMA-MDD provides specific treatment strategies for each stage. Conclusions. The KMA-MDD is the first Korean algorithm for treatment of major depressive disorder. It is based on evidence which supports the efficacy of each treatment, and it has obtained the consensus of Korean experts. We hope that the KMA-MDD will be good practical tool for clinicians who treat major depressive disorder in Korea.     

Obsessive-compulsive disorder in Tourette syndrome

Several lines of evidence suggest a meaningful association between obsessive-compulsive disorder and Tourette syndrome, including comorbidity, phenomenologic overlap, evidence from family and genetic studies, and the possible role of basal ganglia circuitry in both conditions. Obsessive-compulsive behaviors occur frequently in patients who have Tourette syndrome and tend to have a later onset than tics. Despite commonalities, the approaches to treating tics and obsessive-compulsive symptoms are actually quite distinct. A specialized form of cognitive behavior therapy and pharmacotherapy with a potent serotonin reuptake inhibitor are the two established first-line therapies for obsessive-compulsive disorder. An adequate trial of a serotonin reuptake inhibitor is 10 to 12 weeks in duration at doses near the upper end of the recommended range for age and weight. Cases of obsessive-compulsive disorder that do not sufficiently improve with serotonin reuptake inhibitors might benefit from adjunctive low-dose antipsychotic (eg, risperidone) medication whether or not tics are present. Warnings about an increased risk of suicidality among children and adolescents taking antidepressants for pediatric depression extend to those taking the medications for obsessive-compulsive disorder, but the risk-to-benefit ratio is more favorable in this latter population because several serotonin reuptake inhibitors have been shown to be efficacious in obsessive-compulsive disorder.
