Abstract
Thyroid abnormalities are documented consequences of quetiapine treatment. This may have clinical implications as changes in thyroid hormones may deteriorate a person's affective state. Yet less is known about the clinical factors and underlying mechanisms associated with thyroid hormones on quetiapine therapy. We therefore systematically reviewed the published literature of evidence of quetiapine-induced thyroid abnormalities. We searched MEDLINE, PsycINFO, Google Scholar, and EMBASE for articles in which individuals developed biochemically confirmed thyroid abnormalities (with or without clinical symptoms) while on quetiapine treatment. We included case reports, case series, observational, and experimental studies. We included 32 studies, 20 of which were observational and experimental studies. There were 10 case reports and 1 case series. All the research designs suggested an association between quetiapine and hypothyroidism. However, these findings were limited by the quality of the included studies and the general lack of either a clear temporal relationship or dose response. Quetiapine has been associated with thyroid abnormalities, mainly with hypothyroidism. Drug imputability in these abnormalities is not always clear, and the underlying pathophysiology may include immunological and nonimmunological mechanisms. Large prospective studies are required to clarify this association and to further inform the management of patients treated with quetiapine where hypothyroidism occurs.

Br J Clin Pharmacol 2021; 87:4823-4830. [PMID: 34046922 DOI: 10.1111/bcp.14928] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2021] [Revised: 04/30/2021] [Accepted: 05/17/2021] [Indexed: 11/29/2022] Open
Abstract
AIMS To assess association between quetiapine treatment and risk of new-onset hypothyroidism in schizophrenia patients. METHODS We conducted a retrospective cohort study in a tertiary hospital in China between January 2016 and December 2018. Schizophrenia patients with normal thyroid tests at admission were included. Hypothyroidism, which was defined as thyroid-stimulating hormone >4.20 mU/L and free thyroxine <12.00 pmol/L, or on L-thyroxine prescriptions, was the outcome measure, and quetiapine treatment between admission and subsequent thyroid test was the exposure measure of this study. Adjusted relative risks and 95% confidence intervals were used to assess the independent association of quetiapine treatment with risk of new-onset hypothyroidism. The dose-response association was further analysed by 3 quetiapine doses: low (≤<=0.2 g/d), medium (0.2-0.6 g/d), and high (>0.6 g/d). RESULTS A total of 2022 eligible patients were included in the final analysis. Sixty patients (15.0%) in the quetiapine group developed hypothyroidism, while 56 patients (3.5%) in the nonquetiapine group developed hypothyroidism. Relative risk (95% confidence interval) of developing hypothyroidism for quetiapine use was 4.01 (2.86-5.64) after adjusting for several potential confounding factors. A strong dose-response association between quetiapine use and risk of developing hypothyroidism was observed: adjusted relative risks (95% confidence intervals) were 1.00 (0.25-2.59), 4.22 (2.80-6.25) and 5.62 (3.66-8.38), respectively, for low-, medium- and high-dose quetiapine, as compared with no quetiapine. CONCLUSION Acute phase quetiapine treatment for schizophrenia patients was strongly associated with increased risk of developing new-onset hypothyroidism, with a clear dose-response association.

Cardiometabolic Adverse Effects and Its Predictors in Children and Adolescents With First-Episode Psychosis During Treatment With Quetiapine-Extended Release Versus Aripiprazole: 12-Week Results From the Tolerance and Effect of Antipsychotics in Children and Adolescents With Psychosis (TEA) Trial. J Am Acad Child Adolesc Psychiatry 2019; 58:1062-1078. [PMID: 30858012 DOI: 10.1016/j.jaac.2019.01.015] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/07/2018] [Revised: 01/15/2019] [Accepted: 03/01/2019] [Indexed: 10/27/2022]
Abstract
OBJECTIVE To investigate cardiometabolic effects and their predictors in youths with first-episode psychosis (FEP) treated with quetiapine-extended release (ER) versus aripiprazole. METHOD Youths with FEP who were 12 to 17 years of age were randomized to quetiapine-ER or aripiprazole in the 12-week, double-blinded, Tolerability and Efficacy of Antipsychotics (TEA) trial. Primary outcome was change in body weight; secondary outcomes were changes in body mass index (BMI) and waist circumference (WC), blood pressure (BP), heart rate, and lipid and glucose metabolism parameters. Possible predictors of cardiometabolic changes were examined. RESULTS Altogether, 113 patients (schizophrenia-spectrum disorders = 93%; age [mean ± SD] = 15.7 ± 1.4 years; male participants = 30.1%) were randomized to quetiapine-ER (n = 55) or aripiprazole (n = 58). Quetiapine-ER led to significant increases in body weight (4.88 kg, 95% CI = 3.92-5.83, p < .0001), BMI z-score (0.43, 95% CI = 0.33-0.53, p < .0001), and WC z-score (0.97, CI = 0.7-1.23, p < .0001). Changes were significantly smaller with aripiprazole (all between-group p values <.0001): body weight: 1.97 kg (CI = 0.97-2.97, p = .0001), BMI z-score: 0.10 (CI = -0.01 to 0.20, p = .0646), and WC z-score: 0.18 (CI = -0.09 to 0.45, p = .1968). Lipid and glucose metabolism parameters increased significantly at week 4 and week 12 only with quetiapine-ER (p range = 0.0001-0.037). Quetiapine-ER was associated with an increased occurrence of obesity, elevated blood lipids and hyperinsulinemia (p range = 0.004-0.039). Early weight gain, obesity, or type 2 diabetes in the family significantly predicted weight and BMI gain at week 12. CONCLUSION In youths with FEP, quetiapine-ER was associated with significantly greater weight gain and adverse changes in metabolic outcomes than was aripiprazole. Early weight gain must be addressed and family lifestyle factors taken into consideration when treating youths with antipsychotics.

Abstract
Clinical studies indicate that about one-third of pregnant women with psychotic symptoms are exposed to either typical or atypical antipsychotic drugs (APDs). Reports on prenatal subject/model are lacking hence, the present study was undertaken to investigate the effect of prenatal exposure to risperidone (RIS) on the fetal hippocampus, and their related functional changes in young rat offspring. In this study, pregnant Wistar rats were exposed to equivalent therapeutic doses of RIS at 0.8mg/kg, 1.0mg/kg, and 2.0mg/kg BW from gestation days (GD) 6 to 20. On GD 21, about half of the pregnant subjects of each group were euthanized, their fetuses were collected, fetal brains dissected, and processed for neurohistopathological evaluation. Remaining pregnant dams were allowed to deliver naturally and reared up to 8weeks of age for neurobehavioral study under selected paradigms of cognition. Our results indicate that there was a significant decrease in the thickness of fetal hippocampus with the disturbed cytoarchitectural pattern, and volume of striatum and choroid plexus was also reduced. Furthermore, RIS treated young rat offspring displayed memory impairment on different mazes of learning and memory. The current study concludes that maternal exposure to clinically relevant doses of RIS may induce neurostructural changes in developing hippocampus and striatum, and cognitive sequelae in young offspring, respectively. Therefore, caution must be taken before prescribing this drug to pregnant subjects, especially during the sensitive phase of brain development. Hence, clinical correlation of animal data is urgently warranted.

Abstract
The atypical antipsychotic quetiapine has been used in different psychotic and non-psychotic disorders in children and adolescents in randomized clinical trials, open-label studies and chart reviews. Most of these studies suggest that quetiapine may be a promising agent with a potential for use in young patients. The aim of this paper is to critically review available literature on quetiapine in the treatment of children and adolescents with a variety of psychiatric disorders, including psychotic disorders, bipolar disorders (manic and depressive episodes), conduct disorder, autism spectrum disorder, Tourette's syndrome and personality disorders. Furthermore, we report on possible neurochemical pathways involved during treatment with quetiapine, and discuss some issues that are clinically relevant in daily practice, such as titration strategies, safety and tolerability, and monitoring possible side effects. Controlled studies support the short-term efficacy for treating psychosis, mania, and aggression within certain diagnostic categories. However, although quetiapine seems well tolerated in various pediatric populations during acute and intermediate treatments, and hyper-prolactinemia and extra-pyramidal side effects are consistently low among studies, weight gain and alterations in lipid profile need to be closely monitored. Furthermore, the distal benefit/risk ratio during long-term treatment remains to be determined.

Abstract
Objective: To systematically review the efficacy and tolerability data of antipsychotics in children and adolescents with schizophrenia. Materials and Methods: Pubmed, Google scholar and Psych Info were searched to identify studies published in peer-reviewed English language journals. All studies evaluating the efficacy of antipsychotics in children and adolescents with schizophrenia and having 3 or more participants were included. Of the studies identified, only randomized controlled trials were included in the meta-analysis. Data was analysed using effect size calculation as per Cohen's d. Fifty published studies were identified which reported use of antipsychotics in children and adolescents with schizophrenia. Of these, 15 randomized controlled studies were included in meta-analysis. Results: Evidence suggests that both first generation antipsychotics (FGA) and second generation antipsychotics (SGAs) are better than placebo (effect size [ES] 2.948, confidence interval [CI] 1.368 to 4.528, sample size 31; and ES 0.454, CI 0.414 to 0.542, sample size 1308 respectively). However, FGAs seemed to be inferior to SGAs (ES -0.363, CI -0.562 to -0.163, sample size of 243) and clozapine is superior to all other antipsychotics (ES 0.848, CI 0.748 to 0.948, and sample size 85) in treatment of schizophrenia in children and adolescents. The extrapyramidal side effects are more common with FGAs while metabolic adverse effects are more common with SGAs. Conclusion: FGAs and SGAs are effective in the treatment of children and adolescents with schizophrenia. Clozapine apparently is the most effective antipsychotic in this condition.

Abstract
During the last three decades, an increasing understanding of the etiology, psychopathology, and clinical manifestations of schizophrenia spectrum disorders, in addition to the introduction of second-generation antipsychotics, has optimized the potential for recovery from the illness. Continued development of various models of psychosocial intervention promotes the goal of schizophrenia treatment from one of symptom control and social adaptation to an optimal restoration of functioning and/or recovery. However, it is still questionable whether these new treatment approaches can address the patients' needs for treatment and services and contribute to better patient outcomes. This article provides an overview of different treatment approaches currently used in schizophrenia spectrum disorders to address complex health problems and a wide range of abnormalities and impairments resulting from the illness. There are different treatment strategies and targets for patients at different stages of the illness, ranging from prophylactic antipsychotics and cognitive-behavioral therapy in the premorbid stage to various psychosocial interventions in addition to antipsychotics for relapse prevention and rehabilitation in the later stages of the illness. The use of antipsychotics alone as the main treatment modality may be limited not only in being unable to tackle the frequently occurring negative symptoms and cognitive impairments but also in producing a wide variety of adverse effects to the body or organ functioning. Because of varied pharmacokinetics and treatment responsiveness across agents, the medication regimen should be determined on an individual basis to ensure an optimal effect in its long-term use. This review also highlights that the recent practice guidelines and standards have recommended that a combination of treatment modalities be adopted to meet the complex health needs of people with schizophrenia spectrum disorders. In view of the heterogeneity of the risk factors and the illness progression of individual patients, the use of multifaceted illness management programs consisting of different combinations of physical, psychological, and social interventions might be efficient and effective in improving recovery.

Abstract
OBJECTIVE The purpose of this study was to describe the safety, tolerability, and efficacy of quetiapine monotherapy continued for up to 26-weeks in youth with schizophrenia or bipolar I disorder. METHODS Medically healthy boys and girls with a baseline Diagnostic and Statistical Manual of Mental Disorders, 4th ed. (DSM-IV-TR) diagnosis of schizophrenia (ages 13-17 years) or a manic episode of bipolar I disorder (ages 10-17 years) who participated in one of two acute, double-blind, placebo-controlled studies of immediate-release quetiapine were potentially eligible to enroll in a 26-week, open-label study. During the open-label study, quetiapine was flexibly dosed at 400-800 mg/day, with options to reduce dosing to 200 mg/day based on tolerability. Safety and tolerability outcomes assessed from open-label baseline to week 26 included adverse events (AEs), metabolic/laboratory parameters, extrapyramidal symptoms, suicidality, and vital signs. RESULTS Of 381 patients enrolled in the open-label study (n=176, schizophrenia; n=205, bipolar disorder diagnosis), 237 patients (62.2%) completed the 26-week study period (71.0%, schizophrenia; 54.6%, bipolar disorder). The most common AEs reported during the study included somnolence, headache, sedation, weight increase, and vomiting. A total of 14.9% of patients experienced a shift to potentially clinically significant low levels of high-density lipoprotein cholesterol and 10.2% of patients experienced a shift to potentially clinically significant high triglyceride levels. Weight gain ≥ 7% was reported in 35.6% of patients between open-label baseline and final visit. After adjustment for normal growth, 18.3% of study participants experienced clinically significant weight gain (i.e., increase in body mass index ≥ 0.5 standard deviations from baseline). CONCLUSIONS In this 26-week study, quetiapine flexibly dosed at 400-800 mg/day, with options to reduce dosing based on tolerability, was generally safe and well tolerated in youth. Clinicians should monitor lipid profiles and weight gain in youth with schizophrenia or bipolar disorder during treatment with quetiapine.

Weight gain and increase of body mass index among children and adolescents treated with antipsychotics: a critical review. Eur Child Adolesc Psychiatry 2013; 22:457-79.

Abstract
We performed an updated review of the available literature on weight gain and increase of body mass index (BMI) among children and adolescents treated with antipsychotic medications. A PubMed search was conducted specifying the following MeSH terms: (antipsychotic agents) hedged with (weight gain) or (body mass index). We selected 127 reports, including 71 intervention trials, 42 observational studies and 14 literature reviews. Second-generation antipsychotics (SGAs), in comparison with first-generation antipsychotics, are associated with a greater risk for antipsychotic-induced weight gain although this oversimplification should be clarified by distinguishing across different antipsychotic drugs. Among SGAs, olanzapine appears to cause the most significant weight gain, while ziprasidone seems to cause the least. Antipsychotic-induced BMI increase appears to remain regardless of the specific psychotropic co-treatment. Children and adolescents seem to be at a greater risk than adults for antipsychotic-induced weight gain; and the younger the child, the higher the risk. Genetic or environmental factors related to antipsychotic-induced weight gain among children and adolescents are mostly unknown, although certain genetic factors related to serotonin receptors or hormones such as leptin, adiponectin or melanocortin may be involved. Strategies to reduce this antipsychotic side effect include switching to another antipsychotic drug, lowering the dosage or initiating treatment with metformin or topiramate, as well as non-pharmacological interventions. Future research should avoid some methodological limitations such as not accounting for age- and sex-adjusted BMI (zBMI), small sample size, short period of treatment, great heterogeneity of diagnoses and confounding by indication.

Abstract
BACKGROUND Second generation antipsychotics (SGAs) are currently the most prescribed drugs in the treatment of schizophrenia. Despite their advantages, which include greater improvement in negative symptoms, cognitive function, prevention of deterioration, quality of life, and fewer extrapyramidal symptoms, the concern regarding metabolic abnormalities which might cause cardiovascular diseases during treatment with SGAs have been rising. Paraoxonase 1 (PON1) is an enzyme mostly located on high-density lipoprotein particles, and has been shown to protect or inhibit lipoprotein oxidation. Growing evidence suggests that PON1 plays a key role in the pathophysiology of atherosclerosis. METHODS In the present study, we measured serum PON1 activity and serum levels of total cholesterol (TC), triglyceride, high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) in patients with schizophrenia, who had been treated with either olanzapine or quetiapine, and in healthy controls. Thirty five patients who had been treated with olanzapine, 29 patients who had been treated with quetiapine, and 32 age, sex, and smoking status-matched healthy control (HC) participants were enrolled. Serum PON1 activity and serum levels of TC, triglyceride, HDL-C, and LDL-C were measured. RESULTS Serum PON1 activity in the olanzapine group was significantly lower than that of HC and quetiapine groups. Furthermore, serum levels of TC and LDL-C in the olanzapine group were significantly higher than those of quetiapine and HC groups. Interestingly, there was a positive correlation between PON1 activity and HDL-C levels in the olanzapine group. CONCLUSION These findings suggest that serum PON1 activity in patients treated with olanzapine was lower than that of HC and quetiapine groups, and that PON1 may play a role in the metabolic side effects associated with olanzapine treatment. A further study to examine the relationship between serum PON1 activity and cardiovascular and metabolic side effects during treatment with SGAs will be of great interest.

Abstract
OBJECTIVE The purpose of this study was to evaluate the efficacy and safety of acute quetiapine monotherapy in adolescents with schizophrenia. METHODS Patients ages 13-17 years with an American Psychiatric Association, Diagnostic and Statistical Manual of Mental Disorders, 4th ed., Text Revision (DSM-IV-TR) diagnosis of schizophrenia and a Positive and Negative Syndrome Scale (PANSS) total score ≥60 were randomized to 6 weeks of quetiapine (400 or 800 mg/day) or placebo treatment. The primary efficacy measure was change in PANSS total score from baseline to day 42. Safety endpoints included adverse events and assessments of clinical chemistry values, suicidality, and extrapyramidal symptoms. RESULTS The intent-to-treat population included 220 patients. Least-squares mean change in PANSS total score from baseline to endpoint was -27.31 with quetiapine 400 mg/day, -28.44 with quetiapine 800 mg/day, and -19.15 with placebo (p=0.043 and 0.009 for quetiapine 400 and 800 mg/day, respectively, vs. placebo; mixed-model, repeated-measures analysis). Several secondary efficacy outcomes, including Clinical Global Impressions-Improvement score, supported the primary outcome measure in demonstrating significantly greater improvement in quetiapine groups than in the placebo group. Mean changes in body weight at day 42 were 2.2 kg and 1.8 kg for quetiapine 400 and 800 mg/day, respectively, and -0.4 kg for placebo. Mean changes in certain clinical chemistry parameters, including total cholesterol and triglycerides, were numerically greater in the quetiapine groups than in the placebo group. Adverse events associated with quetiapine were mostly mild to moderate in intensity and were consistent with its known profile in adults with schizophrenia. CONCLUSIONS In this 6-week study of adolescent patients, quetiapine at doses of 400 and 800 mg/day provided significant improvements in symptoms associated with schizophrenia in adolescent patients, including the primary efficacy measure of PANSS total score change.

Abstract
Twenty-three adolescents with psychotic disorders, aged from 13 to 18 years, participated in a 12-week open label trial (17 adolescents completed the study) in order to examine the impact of quetiapine on clinical status and cognitive functions (encompassing processing speed, attention, short-term memory, long-term memory and executive function). An improvement in Clinical Global Impression and Positive and Negative Symptom Scale (P's ≤ 0.001) was observed. In addition, after controlling for amelioration of symptoms, a significant improvement was observed on one executive function (P = 0.044; Trail Making Part B). The remaining cognitive abilities showed stability. In addition, we observed an interaction between quetiapine doses (>300 mg/day or <300 mg/day) and time, where lower doses showed more improvement in verbal short-term memory (P = 0.048), inhibition abilities (P = 0.038) and positive symptoms (P = 0.020). The neuropsychological functioning of adolescents with psychotic disorders remained mainly stable after 12 weeks of treatment with quetiapine. However, lower doses seemed to have a better impact on two components of cognition (inhibition abilities and verbal short-term memory) and on positive symptoms.

Abstract
Weight gain is on the rise in the United States as is the diagnosis and treatment of mental disorders. These two phenomena are distinctly separate but tend to overlap in that most psychotropic agents approved for use in the United States are associated with the potential to induce weight gain. Metabolic disorders such as diabetes, hypercholesterolemia, and hypertension are also on the rise and often associated with weight gain and clearly associated with certain psychotropic medications. This article serves to provide a succinct review regarding the epidemiology, etiology, and treatment options for psychotropic-induced obesity.

Abstract
A majority of psychiatric medications are known to generate weight gain and ultimately obesity in some patients. There is much speculation about the prevalence of weight gain and the degree of weight gain during acute and longitudinal treatment with these agents. There is newer literature looking at the etiology of this weight gain and the potential treatments being used to alleviate this side effect. The authors undertook a comprehensive literature review in order to present epidemiology, etiology, and treatment options of weight gain associated with antipsychotics, mood stabilizers, and antidepressants.

Abstract
BACKGROUND Patients receiving second-generation antipsychotics (SGAs) may experience secondary metabolic effects such as weight gain, as well as changes in lipid and glucose metabolism. These effects are well documented in adults; however, fewer studies are available concerning their occurrence and their evolution in children and adolescents. OBJECTIVE The aim of this study was to determine if there is an age-dependent variation in the metabolic effects of SGAs in a drug-naïve population. METHODS Charts of 232 French Canadian patients participating in a program monitoring the metabolic effects of SGAs were retrospectively reviewed. A total of 85 SGA-naïve patients were selected, including 58 youths and 27 adults. Changes, relative to baseline, in weight, body mass index, lipid metabolism (total cholesterol, low-density lipoprotein, high-density lipoprotein, and triglyceride), and fasting blood glucose were assessed, with follow-up at 3, 6, 12, and 24 months. RESULTS With respect to weight gain, in both the youth and adult groups, body mass index significantly increased from baseline at 3 months (10.1% [p < 0.0001] and 12.2% [p < 0.0001], respectively) and 6 months (11.8% [p < 0.0001] and 13.1% [p < 0.0001], respectively). With respect to lipid metabolism, in the youth group, there was no significant change. In the adult group, there was a significant increase at 3 and 6 months in total cholesterol (24.0% [p = 0.004] and 24.1% [p = 0.0006], respectively), low-density lipoprotein (26.8% [p = 0.019] and 30.1% [p = 0.010], respectively), and high-density lipoprotein (10.2% [p = 0.04] and 17.1% [p = 0.005], respectively). There was no significant change in triglyceride and glucose metabolism in both groups. CONCLUSIONS Our results confirm the age-independent effects of SGA on weight gain. However, more data are needed to explore the age effect on glucose and lipid metabolism.

Abstract
Recent clinical trials and case reports have recorded dose-related thyroid function test abnormalities during quetiapine treatment usually requiring drug discontinuation or initiation of thyroid replacement therapy. The authors highlight the potential reversibility of quetiapine-induced hypothyroidism without quetiapine discontinuation in 2 in-patients (a 51-year-old schizophrenic woman and a 46-year-old bipolar man) to which quetiapine (300 and 350 mg/d, respectively) was administered. Both patients had a negative personal and family history of thyroid dysfunction. Significant decreases in T4/free T4 levels and a marked elevation in thyroid-stimulating hormone level were recorded without any clinical signs of hypothyroidism 3 weeks after quetiapine initiation. Antithyroid antibody titers remained within reference range. Thyroid function tests returned to normal 6 weeks after quetiapine initiation, although quetiapine was continued at the same daily dose without thyroid replacement therapy. These are the first cases reporting spontaneous resolution of quetiapine-induced hypothyroidism without quetiapine discontinuation. We suggest careful thyroid monitoring for patients initiating quetiapine. However, physicians can wait in cases of quetiapine-induced hypothyroidism if a close laboratory monitoring is available because thyroid dysregulation may soon resolve.

Abstract
OBJECTIVES Despite known metabolic effects of second-generation antipsychotics (SGAs) on children and adolescents, comparative effects in youth with different diagnoses remain underreported. We compared differences in metabolic changes three months after starting treatment with SGAs in youth with bipolar disorder and with other psychotic and nonpsychotic disorders. METHODS Weight and metabolic differences among diagnostic groups before and three months after starting treatment with SGAs were compared in a naturalistic cohort of children and adolescents (14.9 +/- 3.0 years) diagnosed with bipolar disorder (n = 31), other psychotic disorders (n = 29), and other nonpsychotic disorders (n = 30), with no (35.6%) or very little (6.6 +/- 9.0 days) previous exposure to antipsychotics. Composite measurements of significant weight gain [weight increase > or = 5% at three months or increase > or = 0.5 in body mass index (BMI) z-score] and 'risk for adverse health outcome' (> or = 95(th) BMI percentile, or > or = 85(th) BMI percentile plus presence of one other obesity-related complication) were included. SGAs (risperidone, olanzapine, and quetiapine) were prescribed in comparable proportion among groups. RESULTS Baseline weight and metabolic indices were not significantly different among diagnoses. Three months after starting treatment with SGAs, more than 70% patients had significant weight gain, BMI z-score increased in all diagnostic groups (p < 0.001 for all comparisons), total cholesterol increased in the bipolar (p = 0.02) and psychotic (p = 0.01) disorder groups, low-density lipoprotein cholesterol increased in the bipolar group (p = 0.02), and free T4 decreased in the psychotic disorder group (p = 0.05). More patients with bipolar disorder presented overweight plus > or = 1 obesity-related complication at follow-up. CONCLUSIONS There are early weight gain and metabolic changes across diagnoses in youth treated with SGAs.

Abstract
The objective of this study was to evaluate the efficacy and tolerability of quetiapine in the treatment of first onset psychosis in older adolescents using risperidone as a comparator. Twenty-two patients with first onset psychosis were randomized to receive quetiapine (up to 800 mg/day) or risperidone (up to 6 mg/day) for 6 weeks. Raters blind to treatment assignment performed outcome symptom ratings. No statistical differences emerged in terms of efficacy or tolerability between the two drugs. However, there were some clinically notable differences that seem to favour the efficacy of risperidone over quetiapine. Patients taking quetiapine, although improved, showed less clinical improvement on scores for total positive and negative symptoms, clinical global severity and depression at 6 weeks than patients taking risperidone. Although both treatments were associated with weight gain and sedation, more patients on quetiapine experienced over 10% weight gain. However, fewer patients who were taking quetiapine required anticholinergic medication or experienced extrapyramidal side effects than patients taking risperidone. Risperidone was significantly more likely to be associated with elevation in serum prolactin levels in this population. In conclusion, the results in this small trial show that adolescent patients may benefit more from treatment with risperidone than quetiapine. However, those susceptible to side effects, particularly hyperprolactinaemia, may be more suitable for treatment with quetiapine.

Abstract
OBJECTIVE This review reports the incidence of hyperprolactinemia, its relationship with genotype, and prolactin-related side effects in children and adolescents treated with antipsychotics. METHOD Data on prolactin levels were available for haloperidol, pimozide, risperidone, olanzapine, clozapine, ziprasidone, and quetiapine. Twenty-nine studies were selected after a literature search in the English Medline/Embase/Psychinfo/EBM databases (1965 to August, 2008). RESULTS All antipsychotics, except clozapine, ziprasidone, and quetiapine, increase the mean prolactin level from baseline values of 8.0 ng/mL to 25-28 ng/mL after 4 weeks of treatment (reference range 0-15 ng/mL). The most and best data are available for risperidone. Five risperidone studies (n = 577) show an increase of prolactin level from 7.8 ng/mL to 17.7 ng/mL after 1 year of treatment, and two risperidone studies (n = 60) show an increase from 7.4 ng/mL to 24.9 ng/mL after 2 years of treatment. Aggregated over all antipsychotics, prolactin-related side effects, such as gynecomastia, galactorrhea, irregular menses, and sexual dysfunction, were reported by 4.8% of the children and adolescents. No data are available on bone mineral density in relation to antipsychotic-induced hyperprolactinemia in children and adolescents. Prolactin levels may be influenced by the genetic differences that influence prolactin metabolism and D2 dopamine receptor density. CONCLUSION Persistent elevation of prolactin for periods up to 2 years has been documented in maintenance treatment with risperidone. Very limited long-term data of pimozide, olanzapine, and quetiapine prohibit drawing conclusions for these antipsychotics. Systematic long-term observational studies, including specific questionnaires as well as physical examination, are needed to investigate prolactin-related side effects of antipsychotic treatment in children and adolescents.

Abstract
OBJECTIVE To compare the efficacy, safety, and tolerability of olanzapine and quetiapine in adolescents with first episode psychosis. METHOD Fifty adolescents (age 16 +/- 1.25) with a first episode of psychosis were randomized to quetiapine or olanzapine in a 6-month open label study. Efficacy and side effect scales, as well as vital signs and laboratory data were recorded at baseline, 7, 15, 30, 90, and 180 days (end of study). RESULTS Out of the total sample included in the study, 32 patients completed the trial (quetiapine n = 16, olanzapine n = 16). Patients in both treatment groups had a significant reduction in all clinical scales with the exception of the negative scale of the Positive and Negative Symptom Scale (PANSS) for olanzapine and the general psychopathology scale of the PANSS for quetiapine. The only difference between treatment arms on the clinical scales was observed on the patients' strength and difficulties questionnaire (SDQ) scale, with greater improvement for olanzapine. Patients on olanzapine gained 15.5 kg and patients on quetiapine gained 5.5 kg. CONCLUSION Olanzapine and quetiapine reduced psychotic symptoms in this adolescent sample. Patients on olanzapine gained significantly more weight. Side effects with both drugs seemed to be more prevalent than those reported in adult studies.

Abstract
BACKGROUND Childhood-onset schizophrenia is a serious, chronic and disabling illness that can significantly affect the quality of life of the affected individuals and their families. The affected children commonly show significant premorbid developmental impairment and social abnormalities that may provide an early clinical clue to pursue treatment. Until recent times, treatment approaches for childhood schizophrenia were derived from the adult population. However, given the unique developmental challenges in the pediatric population, this extrapolation may not hold true. OBJECTIVE This review encompasses and elaborates on the efficacy, safety and tolerability data available at present for both typical and atypical antipsychotics for treatment of childhood schizophrenia. METHOD A literature search was conducted on PUBMED with special emphasis on double-blind placebo-controlled studies in childhood schizophrenia. Data from similar studies presented in recent meetings were also added to the review. CONCLUSIONS Recent research in pediatric psychopharmacology has led to the Food and Drug Administration's approval of two atypical antipsychotics for the treatment of schizophrenia. Although data in this age group are still sparse, research in this unique population has grown over the years.

Abstract
OBJECTIVE Persons with schizophrenia die earlier than the general population, in large part due to cardiovascular disease. The study objective was to examine effects of different antipsychotic treatments on estimates of 10-year coronary heart disease (CHD) risk calculated by the Framingham Heart Study formula. METHOD Change in 10-year risk for CHD was compared between treatment groups in 1125 patients followed for 18 months or until treatment discontinuation in the Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE) Schizophrenia Trial. RESULTS The covariate-adjusted mean change in 10-year CHD risk differed significantly between treatments. Olanzapine was associated with a 0.5% (SE 0.3) increase and quetiapine, a 0.3% (SE 0.3) increase; whereas risk decreased in patients treated with perphenazine, -0.5% (SE 0.3), risperidone, -0.6% (SE 0.3), and ziprasidone -0.6% (SE 0.4). The difference in 10-year CHD risk between olanzapine and risperidone was statistically significant (p=0.004). Differences in estimated 10-year CHD risk between drugs were most marked in the tertile of subjects with a baseline CHD risk of at least 10%. Among individual CHD risk factors used in the Framingham formula, only total and HDL cholesterol levels differed between treatments. CONCLUSIONS These results indicate that the impact on 10-year CHD risk differs significantly between antipsychotic agents, with olanzapine producing the largest elevation in CHD risk of the agents studied in CATIE.

Abstract
OBJECTIVE There is a limited evidence base to guide treatment of children and adolescents with nonaffective psychoses because few comparative studies of first-line second-generation antipsychotics (SGAs) have been undertaken. To plan the design of a subsequent randomized controlled trial (RCT), the authors conducted this pilot study to demonstrate the feasibility of the treatment and measurement protocols. METHOD Thirty children and adolescents (20 males, 10 females), ages 10-18 years, who met unmodified Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV) criteria for a schizophrenia-spectrum disorder (schizophrenia, schizoaffective, schizophreniform, psychotic disorder not otherwise specified) were randomized to receive 12 weeks of open-label, flexibly dosed treatment with either risperidone (mean [standard deviation, SD] dose = 3.4 mg [1.5]), olanzapine (mean [SD] dose = 14.0 mg [4.6]) or quetiapine (mean [SD] dose = 611 mg [253.4]). RESULTS Twenty one (70%) of 30 subjects completed the study. There was no overall statistically significant difference with regard to reduction in Positive and Negative Syndrome Scale (PANSS) total scores in treatment efficacy observed (F((2,24)) = 3.13, p = 0.06). However, the possibility of a large differential treatment effect with regard to change in PANSS total scores favoring risperidone relative to quetiapine (risperidone vs. quetiapine, d = 1.10 [95% confidence interval, CI, 0.09-2.01]) was suggested by the point estimate. CONCLUSIONS These preliminary data, viewed together with the extant literature, suggest that a future larger RCT with only two treatment arms may be warranted to establish whether there is a clinically significant differential treatment effect between risperidone and quetiapine for children and adolescents with nonaffective psychoses. Additional challenges and considerations for mounting a larger RCT are explored.

OBJECTIVE The Child and Adolescent First-Episode Psychosis Study (CAFEPS) is a naturalistic longitudinal study of early-onset first psychotic episodes. This report describes the antipsychotic treatment during the first year and compares the most frequently used agents after 6 months. METHODS Participants were 110 patients, aged 9-17 years, with a first psychotic episode attended consecutively at six different centers. The Positive and Negative Symptom Scale (PANSS), Clinical Global Impressions (CGI), Disability Assessment Schedule (DAS), and Global Assessment of Function (GAF) scales were administered at baseline and at 6 months and the Udvalg for Kliniske Undersøgelser (UKU) Side Effects Rating Scale only at 6 months. RESULTS Diagnoses at baseline were 38.2% psychotic disorder not otherwise specified, 39.1% schizophrenia-type disorder, 11.8% depressive disorder with psychotic symptoms, and 10.9% bipolar disorder, manic episode with psychotic symptoms. The most frequently used antipsychotic agents were risperidone (n = 50), quetiapine (n = 18), and olanzapine (n = 16). Patients who were prescribed olanzapine or quetiapine had more negative and general symptoms. Using the baseline score as covariate, no significant differences were found in the reductions on any scale in patients treated with risperidone, quetiapine, or olanzapine for 6 months. Weight increase was greater with olanzapine than with risperidone (p = 0.020) or quetiapine (p = 0.040). More neurological side effects appeared with risperidone than with olanzapine (p = 0.022). All side effects were mild or moderate. CONCLUSIONS Second-generation antipsychotics, especially risperidone, quetiapine, and olanzapine, are the most used in our context in first psychotic episodes in children and adolescents. These three obtain similar clinical improvement, but differ in their side effects.

Abstract
OBJECTIVE The aim of this study was to examine whether quetiapine is superior to placebo in the treatment of adolescents with conduct disorder. METHODS This was a 7-week, randomized, double-blind, placebo-controlled pilot study with two parallel arms. Nine youths were randomly assigned to receive quetiapine, and 10 youths were randomly assigned to receive placebo. Patients were assessed weekly throughout the trial. Quetiapine was dosed twice daily, and medications could be titrated flexibly through the end of study week 5. The dose was fixed for the final 2 weeks of the study. The primary outcome measures were the clinician-assessed Clinical Global Impressions-Severity (CGI-S) and-Improvement (CGI-I) scales. Secondary outcome measures included parent-assessed quality of life, the overt aggression scale (OAS), and the conduct problems subscale of the Conners' Parent Rating Scale (CPRS-CP). RESULTS The final mean dose of quetiapine was 294 +/- 78 mg/day (range 200-600 mg/day). Quetiapine was superior to placebo on all clinician-assessed measures and on the parent-assessed quality of life rating scale. No differences were found on the parent-completed OAS and CPRS-CP. Quetiapine was well tolerated. One patient randomized to quetiapine developed akathisia, requiring medication discontinuation. No other extrapyramidal side effects occurred in patients receiving active drug. CONCLUSIONS This methodologically controlled pilot study provides data that quetiapine may have efficacy in the treatment of adolescents with conduct disorder. Because of the preliminary nature of the study, further research with larger samples is needed to confirm these findings.

Abstract
Patients with bipolar disorder are at high risk of gaining weight and developing metabolic illnesses, and pharmacologic treatment for the disorder may significantly increase this risk. This paper reviews the literature on the metabolic consequences of the medications used in bipolar disorder and describes the possible strategies to prevent, monitor, and treat the common metabolic illnesses that patients with bipolar disorder may develop during treatment.

Abstract
OBJECTIVE The aim of this study was to investigate the effectiveness, tolerability, and safety of quetiapine in adolescents with schizophrenia, schizophreniform, and schizoaffective disorders in a prospective open-label study. METHOD A total of 56 subjects (all-subjects-treated, AST), ages 12-17, received 200-800 mg of quetiapine per day (forced titration to 400 mg within week 1; median study dose 600 mg/day at week 6) in Germany, 2002 through 2004. Primary outcome measure was the change of Positive and Negative Syndrome Scale (PANSS) total score (based on the intent-to-treat (ITT) population, n = 52), secondary outcome measures were changes of PANSS subscales, severity of illness, subjective wellbeing, and safety/tolerability (the latter based on the AST population). Correlates of PANSS response (=50% reduction in PANSS total score) and discontinuation due to lack of effectiveness were analyzed by Cox regression analyses. RESULTS Twenty-seven subjects (48%) completed the study; 17 subjects (30%) were discontinued due to lack of effectiveness. A significant reduction of PANSS total score (last observation carried forward, LOCF; p < 0.0001; effect size = 0.92) and of secondary effectiveness outcomes were detected. In all, 34.6% fulfilled the PANSS response criterion, correlated with the degree of PANSS total change within week 1. Somnolence (21.4%) and fatigue (17.9%) were the most frequent adverse events. A significant mean weight gain (6.2 kg) and mean decrease in total serum thyroxine (2.5 ng/dl) were detected. CONCLUSIONS In this sample of mostly drug-naïve patients with early-onset schizophrenia spectrum disorders, significant reductions in PANSS total and positive scores were detected. Controlled studies are needed to confirm these findings. The significant weight gain with its potentially severe medical consequences must be weighed against quetiapine's effectiveness.

Abstract
Coronary heart disease (CHD) is a major cause of mortality in people who have schizophrenia, and it is caused by many factors relating to lifestyle choices, antipsychotic treatment, and other medical comorbidities. This article focuses on modifiable risk factors such as cigarette smoking, diabetes, hyperlipidemia, hypertension, and the metabolic syndrome, all of which occur more frequently in patients who have schizophrenia than in the general population. Although treatment of risk factors for CHD is still far from ideal, all attempts should be made to strive for wellness to improve patients' long-term outcomes.

Abstract
OBJECTIVE The aim of this study was to compare clinical and health services outcomes in pediatric inpatients prescribed an atypical antipsychotic (AA) to those not prescribed an AA at discharge. METHODS Descriptive statistics, analysis of variance (ANOVA), and, where necessary, analysis of covariance (ANCOVA) were used to compare differences between and within an inpatient group prescribed risperidone, olanzapine, or quetiapine (n=1,131) with an inpatient group not prescribed an antipsychotic at discharge (n=1,741). RESULTS The AA treatment group showed greater psychiatric symptom difficulty at admission as measured by the Brief Psychiatric Rating Scale for Children (Mean BPRS-C) than the group not prescribed AAs (40.3 [n=433] vs. 35.2 [n=452], respectively, p<0.001). AA-treated inpatients also had a higher number of mental health outpatient visits during the 6 months prior to admission. Patients receiving AAs (n=1,050) had significantly longer adjusted length of stay (LOS) than those not receiving antipsychotics (n=1,664): 26.4 days versus 22.4 days, respectively (p<0.04). CONCLUSIONS The findings suggested pediatric inpatients presenting with greater psychiatric symptom difficulty at hospital admission were more likely to be prescribed an AA. Choice of AA may influence certain clinical and health services outcomes. Additional prospective controlled studies evaluating AA efficacy and safety, including head-to-head comparisons, in pediatric inpatients are warranted.

Abstract
Clinical efficacy, safety and tolerability of quetiapine in the treatment of 23 hospitalized psychotic adolescents were evaluated retrospectively. Twelve patients were changed to quetiapine from another antipsychotic medication during their hospital stay. In these patients, CGI-S improved from 4.75+/-0.87 to 2.92+/-0.67 (observation period 3.7+/-1.6 months). The most common adverse events were transient tachycardia and sedation. Mild EPS occurred only in one patient under quetiapine monotherapy. Transaminase increases more than threefold above norm were observed in two patients. fT4 values were slightly below the norm in 67% of the cases. In 11 patients, quetiapine was initiated using a rapid titration schedule with high dosages in the acute phase. Receiving a mean maximum daily dose of 927+/-300 mg, CGI-S improved from 6.00+/-0.63 to 3.18+/-1.25 (observation period 2.9+/-1.8 months). Severe adverse events did not occur. Besides applying lorazepam temporarily in nine of the 11 patients, antipsychotic co-medication was not necessary in this group. In line with other studies, quetiapine may be considered as an effective treatment for adolescents with a severe psychotic disorder showing a favourable side-effect profile. Our preliminary data suggest that a rapid initiation with high doses could be a promising approach in acute psychotic adolescents.

Abstract
Quetiapine was developed in 1985 by scientists at AstraZeneca (formerly Zeneca) Pharmaceuticals. It received official US Food and Drug Administration approval in September 1997 and approval in Germany in 2000. Since then, quetiapine has been used in the treatment of severe mental illness in approximately 70 countries including Canada, most Western European countries, and Japan. Quetiapine is a dibenzothiazepine derivative with a relatively broad receptor binding profile. It has major affinity to cerebral serotonergic (5HT(2A)), histaminergic (H1), and dopaminergic D(1) and D(2) receptors, moderate affinity to alpha(1)- und alpha(2)-adrenergic receptors, and minor affinity to muscarinergic M1 receptors; it demonstrates a substantial selectivity for the limbic system. This receptor occupancy profile with relatively higher affinity for the 5HT(2A) receptor compared with the D(2) receptor is in part responsible for the antipsychotic characteristics and low incidence of extrapyramidal side-effects of quetiapine. The efficacy of quetiapine in reducing positive and negative symptoms of schizophrenia has been proven in several clinical trials with placebo-controlled comparators. Quetiapine has also demonstrated robust efficacy for treatment of cognitive, anxious-depressive, and aggressive symptoms in schizophrenia. Long-term trials show sustained tolerability for a broad spectrum of symptoms. Quetiapine has also proven efficacy and tolerability in the treatment of moderate to severe manic episodes, and in the treatment of juveniles with oppositional-defiant or conduct disorders, and in the geriatric dementia population. Recent data indicate that quetiapine may also be effective in the treatment of bipolar depressive symptoms without increasing the risk of triggering manic episodes, and in borderline personality disorder. In comparison with other antipsychotics, quetiapine has a favorable side-effect profile. In clinical trials only small insignificant prolongations of the QT interval were observed. Weight-gain liabilities and new-onset metabolic side-effects occupy a middle-ground among newer antipsychotics. As a result of its good efficacy and tolerability profile quetiapine has become well established in the treatment of schizophrenia and manic episodes.

Abstract
The purpose of this open-label study was to evaluate the use of olanzapine in the treatment of children and adolescents with schizophrenia. Sixteen children who were 8-17 years of age and met DSM-IV criteria for schizophrenia were admitted into a 10-week, open-label, optimizing dose study of olanzapine. The Brief Psychiatric Rating Scale (BPRS), the Positive and Negative Syndrome Scale (PANSS), and the Clinical Global Impression (CGI)-Severity/Improvement scales were used to assess improvement during the study. Of the 16 subjects who completed the study, 12 demonstrated significant improvement on end of treatment BPRS, CGI, and PANSS scores compared with baseline. Male subjects showed greater improvement and also gained more weight. Weight gain occurred in all but 2 subjects. Weight gain was significant, with patients averaging a gain of about 6.2 kg during the 6-week course of the study. Two of the subjects experienced extrapyramidal symptoms. The average dose of olanzapine for all subjects was 0.17 mg/kg.

Abstract
OBJECTIVE The aim of this study was to describe the long-term safety and effectiveness of quetiapine in conduct disorder (CD). METHODS This was an 18-week outpatient follow-up study of an acute trial that enrolled aggressive children ages 6-12 years with a primary diagnosis of CD. To be enrolled into this study, subjects had to have successfully completed participation in the initial 8-week, open-label, outpatient quetiapine trial. Psychometric measures included the Rating of Aggression Against People and/or Property Scale (RAAPP), the Nisonger Child Behavior Rating Form (NCBRF), the Conners' Parent Rating Scale (CPRS-48), the Clinical Global Impressions Scale of Severity (CGI-S), and the Children's Global Assessment Scale. RESULTS Nine males with a mean age of 8.9 (SD = 1.2) years were treated. The median quetiapine dose at end of study was 150 mg/day (range 75-350). Mean psychometric scores did not change substantively from baseline. No patients experienced extrapyramidal side effects. Three subjects discontinued due to study nonadherence. No patients discontinued treatment due to an adverse event. CONCLUSIONS These preliminary data suggest that quetiapine might be a generally safe and effective maintenance treatment for aggressive children with CD who initially respond to an acute therapeutic trial of quetiapine. More research is needed to confirm or refute these initial findings.

Abstract
Awareness of childhood-onset schizophrenia is rapidly increasing, with a more precise definition now available of the clinical picture and early signs, the outcome and the treatment strategies. Premorbid developmental impairments, including language, motor and social deficits, are more frequent and more pronounced in earlier- than in later-onset forms of schizophrenia. This 'pan-dysmaturation' is reported from the first months of life in more than half of the children who will develop childhood-onset schizophrenia, and it suggests a more severe and early disruption of brain development compared with the adolescent- and adult-onset disorder. The insidious onset in at least 75% of children, the high rates of premorbid problems and the hesitancy on the part of clinicians to make a diagnosis of schizophrenia in a child usually delay the recognition of the syndrome. Elementary auditory hallucinations are the most frequent positive symptom, while visual and tactile hallucinations are rarer. Delusions are less complex than in adolescents and are usually related to childhood themes. Negative symptoms are largely predominant, namely flat or inappropriate affect. A marked deterioration from the previous level of functioning is present in all these children, and an impaired outcome is reported in approximately 50-60% of them. The main diagnostic challenges are with differentiating childhood-onset schizophrenia from affective disorders (both depression and bipolar disorder) with psychotic symptoms, pervasive developmental disorders and severe personality disorders. Post-traumatic stress disorder and obsessive-compulsive disorder without insight may also be misdiagnosed as schizophrenia. Furthermore, approximately 10% of children from the community report nonpsychotic hallucinations or delusions. Finally, children with atypical psychotic features that do not strictly fit diagnostic criteria for schizophrenia have been described, and new labels have been proposed to categorise these clinical patterns, such as multidimensionally impaired disorder and multiple complex developmental disorder. In the context of a multimodal approach, including behavioral, social, scholastic and familial interventions, a pharmacological treatment is usually the core treatment. Available experience from the few controlled studies, open studies and case reports on pharmacotherapy in children with schizophrenia aged <12 years is critically analysed in this review, with particular reference to the use of atypical antipsychotics in clinical practice. To date, the major evidence supports the efficacy of risperidone and olanzapine, while clozapine seems an effective option in treatment-refractory cases. Published experience with newer atypical antipsychotics (quetiapine, ziprasidone, aripiprazole) is still lacking in this age range. Safety data (namely extrapyramidal symptoms, weight gain, hyperprolactinaemia, haematological adverse effects, seizures, hepatotoxicity, metabolic effects, neuroleptic malignant syndrome and cardiovascular effects) are reviewed and discussed, along with strategies for management.

Abstract
Objective. The aim of the study was to assess the therapeutic effect and tolerability of risperidone in patients with early-onset schizophrenia and other related psychotic disorders. Methods. Our retrospective study included 47 schizophrenic patients (27 boys, 20 girls) with an average age of 16.5±1.3 years. The patients were evaluated based on their medical records prior to being started on risperidone, and then after 1, 3 and 6 weeks of risperidone administration. Efficacy of treatment was evaluated using the first item on the CGI scale. Survivors analysis was used. Results. After week 6, the average dose of risperidone was 3.8±1.4 mg. Eighty-two percent of the patients were evaluated as responders, 64% as full responders and 18% as partial responders. There were eight patients who dropped out of the study during treatment. The initial inclusion score on the CGI was 5.8±0.7. This score showed a steady decrease at each evaluation point during the treatment. At week 1 the score was 4.5±1.1 (P<0.001), at week 3, 3.4±1.2 (P<0.001), and at week 6 it was 2.6±1.2 (P<0.001). The medication was well tolerated. Less than half of the patients (46%) reported any side effects, according to their medical records. Parkinsonism (19%), sedation (8.5%) and hypersalivation (8.5%) were the most commonly reported side effects. The mean weight of the participants increased from 61.2±10.0 kg to 64.7±10.0 kg between baseline and week 6 (P=0.002). Conclusion. Our experience supports the use of risperidone in the treatment of schizophrenic disorders in adolescence.

Abstract
OBJECTIVE To examine prevalence of movement disorders (MDs) such as tardive dyskinesia (TD), parkinsonism or akathisia in an adolescent population with schizophrenia and in relationship to predominantly atypical antipsychotic treatment. METHOD Ninety-three patients (aged 19.6+/-2.2 years) were ascertained in this cross-sectional/retrospective study. 76 patients (81.7%) received atypical, 10 (10.8%) typical antipsychotics and 7 (7.5%) combinations of atypical/typical antipsychotics. MD symptoms were assessed using Tardive Dyskinesia Rating Scale (TDRS), Abnormal Involuntary Movement Scale (AIMS), Extrapyramidal Symptom Scale (EPS), Barnes Akathisia Scale (BAS). RESULTS Movement disorder symptoms were found in 37 patients (39.8%) fulfilling strict/subthreshold criteria for TD (5.4/11.8%), parkinsonism (2.2/25.8%) or akathisia (1.1/11.8%), respectively. Patients treated with typical antipsychotics displayed a significantly higher EPS-score (P=0.036) and a tendency towards a higher BAS-score (P=0.061) compared to patients with atypical antipsychotics. Treatment durations with typical/atypical antipsychotics showed trends towards advantages of atypical antipsychotics with regard to parkinsonism/akathisia symptoms (P=0.061; P=0.054), but not with regard to TD symptoms (P=0.003), possibly due to confounding effects. CONCLUSION Under treatment with atypical antipsychotics MD symptoms are less prevalent and less pronounced than under typical antipsychotics. We speculate that the finding of relatively high prevalence rates of subthreshold MD symptoms may be, at least partially, explained by previous or combined therapy with typical antipsychotics.

Abstract
Quetiapine, a dibenzothiazepine derivative, is an atypical antipsychotic, multireceptor antagonist that has a preclinical profile similar to clozapine. Randomized studies have demonstrated the efficacy of quetiapine relative to placebo in the treatment of acute relapse and the long-term management of schizophrenia. Quetiapine is generally well tolerated relative to other antipsychotic medications, although side effects include sedation, orthostatic hypotension, anticholinergic and metabolic side effects. The purpose of this article is to critically review the current literature on quetiapine with an emphasis on emergent themes and key findings in the use of this agent for the treatment of schizophrenia. There are also continued efforts to understand, predict and manage the side-effect risk with quetiapine.

Abstract
OBJECTIVE Despite increasing use of psychotropic medications in children and adolescents, data regarding their efficacy and safety are limited. Endocrine and metabolic adverse effects are among the most concerning adverse effects of commonly used psychotropic medications. METHOD Selective review of endocrine and metabolic effects of psychotropic medications in pediatric populations, with a focus on monitoring and management strategies. RESULTS Because youth are still developing at the time of psychotropic drug exposure, most reference values need to be adjusted for gender and age. As in adults, youngsters receiving lithium require monitoring for thyroid dysfunction. Psychostimulants appear to cause mild reversible growth retardation in some patients, most likely because of decreased weight or slowing of expected weight gain; some patients may experience clinically significant reductions in adult height. Although still controversial, valproate use has been associated with an increased risk for polycystic ovary syndrome, in addition to causing weight gain. Although more data are required, children and adolescents appear to be at higher risk than adults for antipsychotic-induced hyperprolactinemia, weight gain, and possibly, associated metabolic abnormalities, which is of particular concern. CONCLUSIONS Clinicians and caregivers need to be aware of potential endocrine and metabolic adverse effects of psychiatric medications. A careful selection of patients, choice of agents with potentially lesser risk for these adverse events, healthy lifestyle counseling, as well as close health monitoring are warranted to maximize effectiveness and safety.

Abstract
OBJECTIVE To provide an initial description of the effectiveness and pharmacokinetics (PK) of quetiapine in aggressive children with conduct disorder (CD). METHOD This 8-week, open-label outpatient trial, enrolled patients ages 6 to 12 years with CD. Outcome measures included the Rating of Aggression Against People and/or Property Scale (RAAPPS), Nisonger Child Behavior Rating Form (NCBRF), and the Conners Parent Rating Scale (CPRS-48). Blood sampling for PK analyses occurred at the end of weeks 2 and 8. RESULTS Seventeen children (16 boys, mean age 8.9 years) were treated. The mean dose at week 8 was 4.4 mg/kg (SD = 1.1 mg/kg). Significant decreases in the baseline scores of the RAAPPS, and several subscales of the NCBRF and the CPRS were found by the end of the study (p <.05). No patients discontinued because of an adverse event. No patients experienced extrapyramidal side effects. Quetiapine disposition was linear over the dose range studied. The elimination half-life of the drug averaged 3.9 and 2.9 hours and total body clearance averaged 3.5 and 3.0 L/hr/kg after study weeks 2 and 8, respectively. CONCLUSIONS These preliminary data suggest that aggressive children with CD may benefit from quetiapine. The PK of quetiapine supports twice-daily dosing in children with CD.

Abstract
AIMS To explore the potential for drug interactions on quetiapine pharmacokinetics using in vitro and in vivo assessments. METHODS The CYP enzymes responsible for quetiapine metabolite formation were assessed using recombinant expressed CYPs and CYP-selective inhibitors. P-glycoprotein (Pgp) transport was tested in MDCK cells expressing the human MDR1 gene. The effects of CYP3A4 inhibition were evaluated clinically in 12 healthy volunteers that received 25 mg quetiapine before and after 4 days of treatment with ketoconazole 200 mg daily. To assess CYP3A4 induction in vivo, 18 patients with psychiatric disorders were titrated to steady-state quetiapine levels (300 mg twice daily), then titrated to 600 mg daily carbamazepine for 2 weeks. RESULTS CYP3A4 was found to be responsible for formation of quetiapine sulfoxide and N- and O-desalkylquetiapine and not a Pgp substrate. In the clinical studies, ketoconazole increased mean quetiapine plasma C(max) by 3.35-fold, from 45 to 150 ng ml(-1) (mean C(max) ratio 90% CI 2.51, 4.47) and decreased its clearance (Cl/F) by 84%, from 138 to 22 l h(-1) (mean ratio 90% CI 0.13, 0.20). Carbamazepine decreased quetiapine plasma C(max) by 80%, from 1042 to 205 ng ml(-1) (mean C(max) ratio 90% CI 0.14, 0.28) and increased its clearance 7.5-fold, from 65 to 483 l h(-1) (mean ratio 90% CI 6.04, 9.28). CONCLUSIONS Cytochrome P450 3A4 is a primary enzyme responsible for the metabolic clearance of quetiapine. Quetiapine pharmacokinetics were affected by concomitant administration of ketoconazole and carbamazepine, and therefore other drugs and ingested natural products that strongly modulate the activity or expression of CYP3A4 would be predicted to change exposure to quetiapine.

Abstract
OBJECTIVE This naturalistic, cross-sectional study was designed to assess the risk of prolactin level elevation and associated side effects in youths taking long-term atypical antipsychotic medication. METHOD Subjects were enrolled from outpatient child psychiatric treatment settings in upstate New York who were taking risperidone, olanzapine, or quetiapine for at least 6 months. Demographic data, medication history, and side effects were elicited at the initial interview. Two fasting morning serum prolactin levels were obtained 1 month apart, and the results were averaged. RESULTS Fifty outpatient youths, with a median age of 13 years, were enrolled in the study. The median overall duration of use of an atypical antipsychotic was 22.1 months. The median dose of medication for risperidone was 1.5 mg/day, for olanzapine 10 mg/day, and for quetiapine 200 mg/day. The mean prolactin level among all patients on risperidone was significantly greater than controls, as well as for those on quetiapine or olanzapine. CONCLUSIONS The risk of hyperprolactinemia with long-term use of risperidone appears to be significantly greater than for olanzapine or quetiapine. Overt side effects were infrequent in the overall sample, but serum prolactin assessment is recommended for youths taking risperidone chronically. Because of variability found in sequential prolactin samples, repeat samples may be warranted.

Abstract
Although second-generation antipsychotics (SGAs) are used increasingly in children and adolescents, data on the effectiveness and safety in pediatric populations are still sparse. Much of the safety information is derived from studies conducted in adults. This derivation is problematic because children and adolescents are exposed to SGAs during a phase of unparalleled physical and psychologic development that can affect pharmacokinetic and pharmacodynamic drug actions, efficacy, and side-effect patterns. This article presents an overview of SGA-related side effects in children and adolescents and strategies to monitor health outcomes effectively in youngsters receiving SGAs.

Abstract
During puberty, girls may present with psychiatric illness necessitating treatment with psychotropic medications. Pubertal girls are especially vulnerable to medication-associated adverse events. Atypical antipsychotics and antidepressants have the potential to elevate prolactin levels, altering pubertal progression. Selection of prolactin-sparing atypical antipsychotics is recommended, as is treatment with the lowest effective dose of selective serotonin reuptake inhibitors. Monitoring of serum prolactin levels may be necessary.

Abstract
The metabolism of the atypical antipsychotic quetiapine was investigated by in vitro methods. Pharmacokinetic parameters were determined in human liver microsomes and recombinant cytochrome P450 measuring substrate depletion and product formation. The cytochrome P450 isozymes CYP3A4 and CYP2D6 displayed activity towards quetiapine. The isozyme CYP2D6 played a minor role in the metabolism of quetiapine as CYP3A4 contributed 89% to the overall metabolism. A Km value of 18 microM was determined by substrate depletion, suggesting linear kinetics under therapeutic conditions. Drugs known to inhibit CYP3A4, such as ketoconazole and nefazodone, displayed almost complete inhibition at low concentrations, whereas inhibitors of CYP2D6 do not seem to have a clinically relevant effect.

Abstract
Juveniles within the youth justice system have high rates of psychiatric morbidity, including posttraumatic stress disorder (PTSD). This case series describes 6 young people aged 15 to 17 years within a youth detention center who met the criteria for PTSD and reported an improvement in symptoms after 6 weeks of treatment with low-dose quetiapine. The primary outcome measure used was the Traumatic Symptom Checklist in Children. The dose of quetiapine ranged from 50 to 200 mg/d; T scores for PTSD symptoms decreased from 75 (SD, +/-5.2; range, 68-82) to 54 (SD, +/-7.4; range, 43-62) (P < 0.01). Significant improvements in symptoms of dissociation (P < 0.01), anxiety (P < 0.01), depression (P < 0.01), and anger (P < 0.05) were also noted over the 6-week evaluation period. Low-dose quetiapine was tolerated well, with no persisting side effects or adverse events. Nighttime sedation was reported, although this was viewed as beneficial. All young people opted to continue with treatment after the assessment period. This preliminary case series suggests that juveniles in detention who have PTSD may benefit from treatment with quetiapine. Caution is needed in interpreting these findings. Both larger open-label and blinded trials are warranted to define the use of quetiapine in the treatment of PTSD in the adolescent forensic population.

Abstract
The aim of this study was to report on the serum prolactin levels in 70 male youths at a residential treatment center who were treated with either risperidone or quetiapine. This is a cross-sectional retrospective medical chart review of 50 males (mean age, 13.5+/-2.8 years) treated with risperidone (mean dose, 2.4+/-1.6 mg/day) and 20 males (mean age, 13.5+/-2.4 years) treated with quetiapine (mean dose, 317.5+/-238 mg/day). Serum prolactin levels were drawn according to a protocol, after at least 6 weeks of treatment. Prolactin was above the upper limit of normal for 68% of the patients on risperidone and 20% of the patients on quetiapine (chi2 analysis: R>Q; p<0.001). Both risperidone and quetiapine produced dose-related increases in serum prolactin levels (R, r=0.34, p=0.017; Q, r=0.45, p=0.05). No correlation was found between duration of treatment and prolactin levels. Given that hyperprolactinemia secondary to antipsychotic treatment may result in reproductive and growth irregularities, periodic long-term monitoring during treatment with these two atypical antipsychotics (and perhaps others as well) may be warranted.

Abstract
Schizophrenia is a debilitating disorder, which is usually chronic, and is one of the most devastating medical illnesses. Early and appropriate treatment with antipsychotics is an important strategy for patients with first-episode schizophrenia. However, there are many possible safety issues for patients with schizophrenia that should be considered and properly addressed. Depressive symptoms and suicidal behaviour commonly occur in first-episode schizophrenic patients, and every effort should be made to treat and minimise these symptoms. There are also important issues and considerations in young and first-episode patients that should also be considered in the emergency treatment setting and for minimising medication nonadherence in this population. Most importantly, adverse effects should be considered, minimised and addressed. While first- and second-generation antipsychotics (SGAs) both appear to offer similar efficacy for amelioration of positive symptoms in first-episode patients, SGAs may offer better tolerability, specifically regarding extrapyramidal symptoms (EPS) and tardive dyskinesia risk, and some prolactin-sparing benefits. However, these medications do cause a host of adverse effects, including weight gain, metabolic disturbances, corrected QT interval prolongation and prolactin-related adverse effects, which are important considerations relating to both the short- and long-term safety of patients with schizophrenia being treated with SGAs. Clozapine and olanzapine are most likely to cause weight gain and metabolic effects, while risperidone is more likely to cause EPS and prolactin elevations. Most antipsychotics should be used in low doses to minimise adverse effects and each medication should be optimised in a highly individualised way to maximise adherence and treatment outcomes and minimise tolerability and safety concerns. At some point in their lives, these patients will most probably experience periods of depression, suicidal behaviours, adverse effects and nonadherence, and every effort should be made to minimise or prevent these from occurring. Thus, safety concerns in this group of young patients, in the beginning of their first psychotic episode, are a major issue as they are starting a journey of antipsychotic treatment that is likely to last for the remainder of their lives.
