RESUMO

OBJECTIVE: The purpose of this article is to describe the effects of the pediatric antidepressant controversy on the Treatment of Serotonin-Selective Reuptake Inhibitor (SSRI) Resistant Depression in Adolescents (TORDIA) trial. METHOD: Adolescents, ages 12-18 years, with SSRI resistant depression were randomized to one of four treatments for a 12 week trial: Switch to different SSRI, switch to an alternate antidepressant (venlafaxine), switch to an alternate SSRI plus cognitive behavior therapy (CBT), or switch to venlafaxine plus CBT. RESULTS: The health advisories and "black box" warnings regarding suicidality and antidepressants in adolescents occurred during the course of the TORDIA trial. Revisions to the protocol, multiple-consent form changes, and re-consenting of patients were necessary. Recruitment of participants was adversely affected. CONCLUSION: Despite a cascade of unforeseen events that delayed the completion of the study, the TORDIA trial resulted in clinically important information about treatment-resistant depression in adolescents.

RESUMO

The Studies to Advance Autism Research and Treatment Network conducted a randomized trial with citalopram in children with Pervasive developmental disorders (PDDs). We present the rationale, design and sample characteristics of the citalopram trial. Subjects (128 boys, 21 girls) had a mean age of 9.3 (±3.12) years; 132 (88.6%) were diagnosed with autistic disorder (4.7% with Asperger's Disorder; 6.7% with PDD-not otherwise specified). Less than half of the subjects were intellectually disabled; 117 (78.5%) were rated Moderate or Marked on the Clinical Global Impression for Severity. Study measures were similar to previous Research Units on Pediatric Psychopharmacology trials. Subjects in this trial were slightly older and more likely to have complaints of repetitive behavior than participants in RUPP trials.

RESUMO

OBJECTIVE: To examine the long-term safety and efficacy of three antipsychotics in early-onset schizophrenia spectrum disorders. METHOD: Patients (8 to 19 years old) who had improved during an 8-week, randomized, double-blind acute trial of olanzapine, risperidone, or molindone (plus benztropine) were eligible to continue on the same medication for up to 44 additional weeks under double-blind conditions. Adjunctive medications were allowed according to defined algorithms. Standardized symptom, safety, and functional assessments were conducted every 4 weeks. RESULTS: Of the 116 youths randomized in the acute trial, 54 entered maintenance treatment (molindone, n = 20; olanzapine, n = 13; risperidone, n = 21). Fourteen (26%) completed 44 weeks of treatment. Adverse effects (n = 15), inadequate efficacy (n = 14), or study nonadherence (n = 8) were the most common reasons for discontinuation. The three treatment arms did not significantly differ in symptom decrease or time to discontinuation. Akathisia was more common with molindone and elevated prolactin concentrations more common with risperidone. Although weight gain and metabolic adverse events had occurred more often with olanzapine and risperidone during the acute trial, no significant between-drug differences emerged in most of these parameters during maintenance treatment. CONCLUSIONS: Only 12% of youths with early-onset schizophrenia spectrum disorders continued on their originally randomized treatment at 52 weeks. No agent demonstrated superior efficacy, and all were associated with side effects, including weight gain. Improved treatments are needed for early-onset schizophrenia spectrum disorders.

RESUMO

OBJECTIVE: Guanfacine has been shown to reduce hyperactive behaviors in children with attention-deficit/hyperactivity disorder (ADHD) and possibly in children with pervasive developmental disorder (PDD) and hyperactivity. The aim of this exploratory study was to examine whether gene variants encoding the multidrug resistance protein (MDR1 or ABCB1) , a drug transporter at the blood-brain barrier, are associated with variability in the efficacy of guanfacine in children with PDD and hyperactivity. METHODS: Children with PDD who participated in an 8-week open-label trial of guanfacine were genotyped for the C3435T single-nucleotide polymorphism (SNP) variant of the MDR1 gene, a variant reported to alter function of the transporter. The decrease from baseline to 8 weeks in parent-rated Aberrant Behavior Checklist (ABC) hyperactivity and Swanson, Nolan, and Pelham (SNAP) scores were analyzed by MDR1 genotype. Response was compared between subjects homozygous for the minor allele T of the C34535T MDR1 variant (T/T) versus other genotypes (C/T and C/C). RESULTS: Disruptive behavior decreased during guanfacine treatment as assessed by several end points in the 25 enrolled children (23 boys and 2 girls). Genotype data were available from 22 children. Subjects with either C/T or C/C (n = 16) genotypes showed a three-fold greater improvement than T/T MDR1 C3435T genotype (n = 6) (mean decrease of 15.1 +/- 12.6, or 50.7% from baseline, versus 4.5 +/- 5.1, or 15.6% from baseline) in parent-rated ABC Hyperactivity scores over 8 weeks (p = 0.03). Parent-rated ADHD SNAP scores also differed by genotype (p = 0.05). CONCLUSIONS: Gene variants in MDR1 may influence guanfacine response on hyperactive-impulsive behaviors via altered membrane transport. If replicated in larger samples, additional studies would be important to clarify the mechanisms underlying this effect and to determine its clinical significance. 2.

RESUMO

OBJECTIVE: Many children with pervasive developmental disorders (PDDs) have serious, functionally impairing behavioral problems. We tested whether combined treatment (COMB) with risperidone and parent training (PT) in behavior management is superior to medication alone (MED) in improving severe behavioral problems in children with PDDs. METHOD: This 24-week, three-site, randomized, parallel-groups clinical trial enrolled 124 children, aged 4 through 13 years, with PDDs, accompanied by frequent tantrums, self-injury, and aggression. The children were randomized 3:2 to COMB (n = 75) or MED (n = 49). The participants received risperidone monotherapy from 0.5 to 3.5 mg/day (with switch to aripiprazole if risperidone was ineffective). Parents in the COMB group (n = 75; 60.5%) received a mean of 10.9 PT sessions. The primary measure of compliance was the Home Situations Questionnaire (HSQ) score. RESULTS: Primary: intent-to-treat random effects regression showed that COMB was superior to MED on HSQ (p = .006) [effect size at week 24 (d) = 0.34]. The HSQ score declined from 4.31 (± 1.67) to 1.23 (± 1.36) for COMB compared with 4.16 (± 1.47) to 1.68 (± 1.36) for MED. Secondary: groups did not differ on Clinical Global Impressions-Improvement scores at endpoint; compared with MED, COMB showed significant reductions on Aberrant Behavior Checklist Irritability (d = 0.48; p = .01), Stereotypic Behavior (d = 0.23; p = .04), and Hyperactivity/Noncompliance subscales (d = 0.55; p = .04). Final risperidone mean dose for MED was 2.26 mg/day (0.071 mg/kg), compared with 1.98 mg/day for COMB (0.066 mg/kg) (p = .04). CONCLUSIONS: Medication plus PT resulted in greater reduction of serious maladaptive behavior than MED in children with PDDs, with a lower risperidone dose.

RESUMO

CONTEXT: Selective serotonin reuptake inhibitors are widely prescribed for children with autism spectrum disorders. OBJECTIVES: To determine the efficacy and safety of citalopram hydrobromide therapy for repetitive behavior in children with autism spectrum disorders. DESIGN: National Institutes of Health-sponsored randomized controlled trial. SETTING: Six academic centers, including Mount Sinai School of Medicine, North Shore-Long Island Jewish Health System, University of North Carolina at Chapel Hill, University of California at Los Angeles, Yale University, and Dartmouth Medical School. PARTICIPANTS: One hundred forty-nine volunteers 5 to 17 years old (mean [SD] age, 9.4 [3.1] years) were randomized to receive citalopram (n = 73) or placebo (n = 76). Participants had autistic spectrum disorders, Asperger disorder, or pervasive developmental disorder, not otherwise specified; had illness severity ratings of at least moderate on the Clinical Global Impressions, Severity of Illness Scale; and scored at least moderate on compulsive behaviors measured with the Children's Yale-Brown Obsessive Compulsive Scales modified for pervasive developmental disorders. INTERVENTIONS: Twelve weeks of citalopram hydrobromide (10 mg/5 mL) or placebo. The mean (SD) maximum dosage of citalopram hydrobromide was 16.5 (6.5) mg/d by mouth (maximum, 20 mg/d). MAIN OUTCOME MEASURES: Positive response was defined by a score of much improved or very much improved on the Clinical Global Impressions, Improvement subscale. An important secondary outcome was the score on the Children's Yale-Brown Obsessive Compulsive Scales modified for pervasive developmental disorders. Adverse events were systematically elicited using the Safety Monitoring Uniform Report Form. RESULTS: There was no significant difference in the rate of positive response on the Clinical Global Impressions, Improvement subscale between the citalopram-treated group (32.9%) and the placebo group (34.2%) (relative risk, 0.96; 95% confidence interval, 0.61-1.51; P > .99). There was no difference in score reduction on the Children's Yale-Brown Obsessive Compulsive Scales modified for pervasive developmental disorders from baseline (mean [SD], -2.0 [3.4] points for the citalopram-treated group and -1.9 [2.5] points for the placebo group; P = .81). Citalopram use was significantly more likely to be associated with adverse events, particularly increased energy level, impulsiveness, decreased concentration, hyperactivity, stereotypy, diarrhea, insomnia, and dry skin or pruritus. CONCLUSION: Results of this trial do not support the use of citalopram for the treatment of repetitive behavior in children and adolescents with autism spectrum disorders.

RESUMO

OBJECTIVE: The authors sought to identify predictors of self-harm adverse events in treatment-resistant, depressed adolescents during the first 12 weeks of treatment. METHOD: Depressed adolescents (N=334) who had not responded to a previous trial with an SSRI antidepressant were randomized to a switch to either another SSRI or venlafaxine, with or without cognitive behavior therapy. Self-harm events, i.e., suicidal and non-suicidal self-injury adverse events were assessed by spontaneous report for the first 181 participants, and by systematic weekly assessment for the last 153 participants. RESULTS: Higher rates of suicidal (20.8% vs. 8.8%) and nonsuicidal self-injury (17.6% vs. 2.2%), but not serious adverse events (8.4% vs. 7.3%) were detected with systematic monitoring. Median time to a suicidal event was 3 weeks, predicted by high baseline suicidal ideation, family conflict, and drug and alcohol use. Median time to nonsuicidal self-injury was 2 weeks, predicted by previous history of nonsuicidal self-injury. While there were no main effects of treatment, venlafaxine treatment was associated with a higher rate of self-harm adverse events in those with higher suicidal ideation. Adjunctive use of benzodiazepines, while in a small number of participants (N=10) was associated with higher rate of both suicidal and nonsuicidal self-injury adverse events. CONCLUSIONS: Since predictors of suicidal adverse events also predict poor response to treatment, and many of these events occurred early in treatment, improving the speed of response to depression, by targeting of family conflict, suicidal ideation, and drug use may help to reduce their incidence. The relationship of venlafaxine and of benzodiazepines to self-harm events requires further study and clinical caution.

RESUMO

OBJECTIVE: To advance knowledge regarding strategies for treating selective serotonin reuptake inhibitor (SSRI)-resistant depression in adolescents, we conducted a randomized controlled trial evaluating alternative treatment strategies. In primary analyses, cognitive-behavioral therapy (CBT) combined with medication change was associated with higher rates of positive response to short-term (12-week) treatment than medication alone. This study examines predictors and moderators of treatment response, with the goal of informing efforts to match youths to optimal treatment strategies. METHOD: Youths who had not improved during an adequate SSRI trial (N = 334) were randomized to an alternative SSRI, an alternative SSRI plus CBT, venlafaxine, or venlafaxine plus CBT. Analyses examined predictors and moderators of treatment response. RESULTS: Less severe depression, less family conflict, and absence of nonsuicidal self-injurious behavior predicted better treatment response status. Significant moderators of response to CBT + medication (combined) treatment were number of comorbid disorders and abuse history; hopelessness was marginally significant. The CBT/combined treatment superiority over medication alone was more evident among youths who had more comorbid disorders (particularly attention-deficit/hyperactivity disorder and anxiety disorders), no abuse history, and lower hopelessness. Further analyses revealed a stronger effect of combined CBT + medication treatment among youths who were older and white and had no nonsuicidal self-injurious behavior and longer prestudy pharmacotherapy. CONCLUSIONS: Combined treatment with CBT and antidepressant medication may be more advantageous for adolescents whose depression is comorbid with other disorders. Given the additional costs of adding CBT to medication, consideration of moderators in clinical decision making can contribute to a more personalized and effective approach to treatment.

RESUMO

This paper presents the rationale for a 24-week, randomized trial designed to test whether risperidone plus structured parent training would be superior to risperidone only on measures of noncompliance, irritability and adaptive functioning. In this model, medication reduces tantrums, aggression and self-injury; parent training promotes improvement in noncompliance and adaptive functioning. Thus, medication and parent training target related, but separate, outcomes. At week 24, the medication was gradually withdrawn to determine whether subjects in the combined treatment group could be managed on a lower dose or off medication without relapse. Both symptom reduction and functional improvement are important clinical treatment targets. Thus, experimental evidence on the beneficial effects of combining pharmacotherapy and exportable behavioral interventions is needed to guide clinical practice.

RESUMO

Objective To evaluate gastrointestinal (GI) problems in a large, well-characterized sample of children with pervasive developmental disorders (PDDs). Methods One hundred seventy two children entering one of two trials conducted by the Research Units on Pediatric Psychopharmacology (RUPP) Autism Network were assessed comprehensively prior to starting treatment and classified with regard to GI symptoms. Results Thirty nine (22.7%) were positive for GI problems, primarily constipation and diarrhea. Those with GI problems were no different from subjects without GI problems in demographic characteristics, measures of adaptive functioning, or autism symptom severity. Compared to children without GI problems, those with GI problems showed greater symptom severity on measures of irritability, anxiety, and social withdrawal. Those with GI problems were also less likely to respond to treatment.

RESUMO

This report examined the effect of methylphenidate on social communication and self-regulation in children with pervasive developmental disorders and hyperactivity in a secondary analysis of RUPP Autism Network data. Participants were 33 children (29 boys) between the ages of 5 and 13 years who participated in a four-week crossover trial of placebo and increasing doses of methylphenidate given in random order each for one week. Observational measures of certain aspects of children's social communication, self-regulation, and affective behavior were obtained each week. A significant positive effect of methylphenidate was seen on children's use of joint attention initiations, response to bids for joint attention, self-regulation, and regulated affective state. The results go beyond the recent literature and suggest that methylphenidate may have positive effects on social behaviors in children with PDD and hyperactivity.

RESUMO

OBJECTIVE: Atypical (second-generation) antipsychotics are considered standard treatment for children and adolescents with early-onset schizophrenia and schizoaffective disorder. However, the superiority of second-generation antipsychotics over first-generation antipsychotics has not been demonstrated. This study compared the efficacy and safety of two second-generation antipsychotics (olanzapine and risperidone) with a first-generation antipsychotic (molindone) in the treatment of early-onset schizophrenia and schizoaffective disorder. METHOD: This double-blind multisite trial randomly assigned pediatric patients with early-onset schizophrenia and schizoaffective disorder to treatment with either olanzapine (2.5-20 mg/day), risperidone (0.5-6 mg/day), or molindone (10-140 mg/day, plus 1 mg/day of benztropine) for 8 weeks. The primary outcome was response to treatment, defined as a Clinical Global Impression (CGI) improvement score of 1 or 2 and >or=20% reduction in Positive and Negative Syndrome Scale (PANSS) total score after 8 weeks of treatment. RESULTS: In total, 119 youth were randomly assigned to treatment. Of these subjects, 116 received at least one dose of treatment and thus were available for analysis. No significant differences were found among treatment groups in response rates (molindone: 50%; olanzapine: 34%; risperidone: 46%) or magnitude of symptom reduction. Olanzapine and risperidone were associated with significantly greater weight gain. Olanzapine showed the greatest risk of weight gain and significant increases in fasting cholesterol, low density lipoprotein, insulin, and liver transaminase levels. Molindone led to more self-reports of akathisia. CONCLUSIONS: Risperidone and olanzapine did not demonstrate superior efficacy over molindone for treating early-onset schizophrenia and schizoaffective disorder. Adverse effects were frequent but differed among medications. The results question the nearly exclusive use of second-generation antipsychotics to treat early-onset schizophrenia and schizoaffective disorder. The safety findings related to weight gain and metabolic problems raise important public health concerns, given the widespread use of second-generation antipsychotics in youth for nonpsychotic disorders.

RESUMO

OBJECTIVE: The objective of this research was to explore the effects of risperidone on cognitive processes in children with autism and irritable behavior. METHOD: Thirty-eight children, ages 5-17 years with autism and severe behavioral disturbance, were randomly assigned to risperidone (0.5 to 3.5 mg/day) or placebo for 8 weeks. This sample of 38 was a subset of 101 subjects who participated in the clinical trial; 63 were unable to perform the cognitive tasks. A double-blind placebo-controlled parallel groups design was used. Dependent measures included tests of sustained attention, verbal learning, hand-eye coordination, and spatial memory assessed before, during, and after the 8-week treatment. Changes in performance were compared by repeated measures ANOVA. RESULTS: Twenty-nine boys and 9 girls with autism and severe behavioral disturbance and a mental age >or=18 months completed the cognitive part of the study. No decline in performance occurred with risperidone. Performance on a cancellation task (number of correct detections) and a verbal learning task (word recognition) was better on risperidone than on placebo (without correction for multiplicity). Equivocal improvement also occurred on a spatial memory task. There were no significant differences between treatment conditions on the Purdue Pegboard (hand-eye coordination) task or the Analog Classroom Task (timed math test). CONCLUSION: Risperidone given to children with autism at doses up to 3.5 mg for up to 8 weeks appears to have no detrimental effect on cognitive performance.

RESUMO

BACKGROUND: Although epidemiologic research consistently reports greater prevalence of major depressive disorder in women, small sample sizes in many studies do not allow for full elaboration of illness characteristics. This article examines sex differences in terms of illness attributes in a cohort of 2541 outpatients from across the United States who enrolled in the Sequenced Treatment Alternatives to Relieve Depression study. METHODS: Confirmatory analyses were performed in 2541 outpatients comparing men and women with regard to sociodemographic features, comorbid Axis I and Axis III conditions, and illness characteristics. Results were compared with those of our previous report on the initial population of the first 1500 individuals enrolled in Sequenced Treatment Alternatives to Relieve Depression study. RESULTS: In both samples, nearly two thirds of the sample (62.5%) were women. Women had greater symptom severity, but men had more episodes of major depression, despite no difference in the length of illness. No differences in age of onset emerged. As in the first cohort, women showed greater rates of an anxiety disorder, bulimia, and somatoform disorder, as well as more past suicide attempts, whereas men showed more alcohol and substance abuse. Women reported more appetite, weight, hypersomnia, interpersonal sensitivity, gastrointestinal and pain complaints, and less suicidal ideation. Irritability was equally common in men and women. CONCLUSION: This large analysis confirmed most of the clinical features and comorbidities found to be more prevalent in the first cohort of women. In addition, this analysis corroborated previous research suggesting higher rates of atypical and anxious depression in women but refuted the notion of an "irritable depression" found in men. The report confirmed the 1.7:1 ratio for depression seen across sexes in the National Comorbidity Survey.

RESUMO

CONTEXT: Only about 60% of adolescents with depression will show an adequate clinical response to an initial treatment trial with a selective serotonin reuptake inhibitor (SSRI). There are no data to guide clinicians on subsequent treatment strategy. OBJECTIVE: To evaluate the relative efficacy of 4 treatment strategies in adolescents who continued to have depression despite adequate initial treatment with an SSRI. DESIGN, SETTING, AND PARTICIPANTS: Randomized controlled trial of a clinical sample of 334 patients aged 12 to 18 years with a primary diagnosis of major depressive disorder that had not responded to a 2-month initial treatment with an SSRI, conducted at 6 US academic and community clinics from 2000-2006. INTERVENTIONS: Twelve weeks of: (1) switch to a second, different SSRI (paroxetine, citalopram, or fluoxetine, 20-40 mg); (2) switch to a different SSRI plus cognitive behavioral therapy; (3) switch to venlafaxine (150-225 mg); or (4) switch to venlafaxine plus cognitive behavioral therapy. MAIN OUTCOME MEASURES: Clinical Global Impressions-Improvement score of 2 or less (much or very much improved) and a decrease of at least 50% in the Children's Depression Rating Scale-Revised (CDRS-R); and change in CDRS-R over time. RESULTS: Cognitive behavioral therapy plus a switch to either medication regimen showed a higher response rate (54.8%; 95% confidence interval [CI], 47%-62%) than a medication switch alone (40.5%; 95% CI, 33%-48%; P = .009), but there was no difference in response rate between venlafaxine and a second SSRI (48.2%; 95% CI, 41%-56% vs 47.0%; 95% CI, 40%-55%; P = .83). There were no differential treatment effects on change in the CDRS-R, self-rated depressive symptoms, suicidal ideation, or on the rate of harm-related or any other adverse events. There was a greater increase in diastolic blood pressure and pulse and more frequent occurrence of skin problems during venlafaxine than SSRI treatment. CONCLUSIONS: For adolescents with depression not responding to an adequate initial treatment with an SSRI, the combination of cognitive behavioral therapy and a switch to another antidepressant resulted in a higher rate of clinical response than did a medication switch alone. However, a switch to another SSRI was just as efficacious as a switch to venlafaxine and resulted in fewer adverse effects. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT00018902.

RESUMO

OBJECTIVE: The Treatment of Early Onset Schizophrenia Spectrum Disorders Study is a publicly funded clinical trial designed to compare the therapeutic benefits, safety, and tolerability of risperidone, olanzapine, and molindone in youths with early-onset schizophrenia spectrum disorders. The rationale, design, and methods of the Treatment of Early Onset Schizophrenia Spectrum Disorders Study are described. METHOD: Using a randomized, double-blind, parallel-group design at four sites, youths with EOSS (ages 8-19 years) were assigned to an 8-week acute trial of risperidone (0.5-6.0 mg/day), olanzapine (2.5-20 mg/day), or molindone (10-140 mg/day). Responders continued double-blind treatment for 44 weeks. The primary outcome measure was responder status at 8 weeks, defined by a 20% reduction in baseline Positive and Negative Symptom Scale scores plus ratings of significant improvement on the Clinical Global Impressions. Secondary outcome measures included assessments of psychopathology, functional impairment, quality of life, and medication safety. An intent-to-treat analytic plan was used. RESULTS: From February 2002 to May 2006, 476 youths were screened, 173 were further evaluated, and 119 were randomized. Several significant study modifications were required to address safety, the use of adjunctive medications, and the termination of the olanzapine treatment arm due to weight gain. CONCLUSIONS: The Treatment of Early Onset Schizophrenia Spectrum Disorders Study will inform clinical practice regarding the use of antipsychotic medications for youths with early-onset schizophrenia spectrum disorders. Important safety concerns emerged during the study, including higher than anticipated rates of suicidality and problems tapering thymoleptic agents before randomization.

RESUMO

OBJECTIVE: We examined baseline demographic and clinical profiles of youths enrolled from 2001 to 2006 in the publicly funded multicenter, randomized controlled trial Treatment of Early-Onset Schizophrenia Spectrum Disorders. METHOD: Youths (8-19 years) with schizophrenia (SZ) and schizoaffective disorder were recruited at four academic sites. Diagnosis was made via structured and clinical interviews. Assessments of psychiatric symptoms and social and global functioning were included. RESULTS: A total of 119 youths were enrolled. The mean age at illness onset was 11.1 +/- 3.5 years. Patients with SZ and schizoaffective disorder had similar ratings on the Positive and Negative Symptom Scale, Brief Psychiatric Rating Scale for Children, and Clinical Global Impression-Severity Scale. The overall level of functioning was similar in the two groups. A comparison to published reports of adults with SZ indicates that these youths may have more severe symptoms based on results of the Positive and Negative Symptom Scale. CONCLUSIONS: This is one of the largest samples of youths with SZ spectrum disorders studied to date and the largest assessment of youths with schizoaffective disorder. High rates of symptoms and general psychopathology were noted. There was a substantial degree of social and functional impairment. The symptom profiles are consistent with, but more severe than, those reported in the adult literature.

RESUMO

The success of well-developed protocols has been limited in real-world practice, where even effective strategies have not been sufficient to meet patient needs in routine clinical care owing to Axis I and III comorbidities. The Sequenced Treatment Alternatives to Relieve Depression (STAR(*)D) trial required that antidepressant medication treatment be optimal regarding dose and duration, yet accommodate flexibility to ensure safety given the wide range of comorbid general medical and psychiatric disorders allowed in the trial. The objective of this study was to develop a measurement-based care (MBC) approach and an automated feedback system to ensure adequate and safe antidepressant treatment delivery suitable for both clinical research and routine practice. Ratings of depressive symptom severity and side-effect frequency, intensity, and burden were obtained at each treatment visit using the MBC system that (1) guided medication dose adjustments and treatment duration, (2) documented clinician adherence to treatment recommendations, and (3) provided prompt feedback to clinicians to enhance appropriate treatment decisions. Physician adherence to protocol-specific treatment was monitored based on measured symptoms and side-effect burden, and dose and duration of antidepressant at each critical decision point during the acute phase treatment of major depression. Feedback was provided at the point of care by the clinical coordinators, assisted by Web-based reports following each treatment visit. On the basis of the first treatment step with citalopram, over 85% of treatment encounters had appropriate fidelity to recommendations. Most deviations from treatment recommendations occurred late in treatment and were often justifiable. MBC proved to be feasible and effective in busy primary and psychiatric settings. This approach signals a paradigm shift toward the use of measurement-based clinical decisions, both at the point of care and following each visit, to deliver optimal pharmacotherapy for depression.

RESUMO

OBJECTIVES: Clinical research projects gather large amounts of data. Typically, information is captured on paper source documents for later transcription to an electronic format, where responses can be checked, and errors, omissions, and inconsistencies can be resolved. These steps contribute delays, cost, and complexity to clinical research, particularly in large-scale multi-site investigations. To address these issues, we used a mobile computing device with a touch-screen display ("tablet PC") to capture clinical data from depressed patients directly into electronic format. We then examined ease of use, the equivalence of responses between paper and electronic methods, and the acceptability of the tablet PC for this clinical population. SETTINGS: Outpatient clinics at four medical centers. METHODS: 80 adults with major depressive disorder (MDD) completed the 16-item Quick Inventory of Depressive Symptomatology--Self-Rated (QIDS-SR(16)), using both traditional paper forms and an electronic representation of the same questions; participants also completed a survey to evaluate their experience. RESULTS: QIDS-SR(16) responses from paper and electronic versions were highly correlated (mean total: 15.3 (SD=5.2) electronic vs. 15.1 (SD=5.2) paper format), and showed high inter-rating reliability for overall score (intra-class correlation 0.987 (with a 95%CI [0.979,0.992])) and high degree of association for individual symptom items. Participants found both methods acceptable and overall found the electronic implementation easier to use. CONCLUSIONS: QIDS-SR(16) values collected electronically from research participants were equivalent to those collected using traditional paper self-assessment forms. Participants with MDD found the tablet PC version to be acceptable and easier to use than the paper forms.

RESUMO

OBJECTIVE: A common complaint for children with pervasive developmental disorder (PDD) is hyperactivity. The purpose of this pilot study was to gather preliminary information on the efficacy of guanfacine in children with PDD and hyperactivity. METHODS: Children with PDD accompanied by hyperactivity entered the open-label trial if there was a recent history of failed treatment with methylphenidate or the child did not improve on methylphenidate in a multisite, placebo-controlled trial. RESULTS: Children (23 boys and 2 girls) with a mean age of 9.03 (+/-3.14) years entered the open-label trial. After 8 weeks of treatment, the parent-rated Hyperactivity subscale of the Aberrant Behavior Checklist (ABC) went from a mean of 31.3 (+/-8.89) at baseline to 18.9 (+/-10.37) (effect size = 1.4; p < 0.001). The teacher-rated Hyperactivity subscale decreased from a mean of 29.9 (+/-9.12) at baseline to 22.3 (+/-9.44) (effect size = 0.83; p < 0.01). Twelve children (48%) were rated as Much Improved or Very Much Improved on the Clinical Global Impressions- Improvement. Doses ranged from 1.0 to 3.0 mg/day in two or three divided doses. Common adverse effects included irritability, sedation, sleep disturbance (insomnia or midsleep awakening), and constipation. Irritability led to discontinuation in 3 subjects. There were no significant changes in pulse, blood pressure, or electrocardiogram. CONCLUSIONS: Guanfacine may be useful for the treatment of hyperactivity in children with PDD. Placebo-controlled studies are needed to guide clinical practice.
