Project among African-Americans to explore risks for schizophrenia (PAARTNERS): recruitment and assessment methods.

The Project among African-Americans to Explore Risks for Schizophrenia (PAARTNERS) is a multi-site, NIMH-funded study that seeks to identify genetic polymorphisms that confer susceptibility to schizophrenia among African-Americans by linkage mapping and targeted association analyses. Because deficits in certain dimensions of cognitive ability are thought to underlie liability to schizophrenia, the project also examines cognitive abilities in individuals affected by schizophrenia and their extended family members. This article describes PAARTNERS study design, ascertainment methods and preliminary sample characteristics. We aim to recruit a sample of 1260 African-American families, all of whom have at least one proband with schizophrenia or schizoaffective disorder. The data collection protocol includes a structured Diagnostic Interview for Genetic Studies, Family Interview for Genetic Studies, focused neurocognitive assessment, medical records review, and the collection of blood or buccal cells for genetic analyses. We have currently completed study procedures for 106 affected sib-pair, 457 case-parent trio and 23 multiplex families. A total of 289 probands have completed the best estimate final diagnosis process and 1153 probands and family members have been administered the computerized neuropsychological battery. This project lays the foundation for future analysis of cognitive and behavioral endophenotypes. This novel integration of diagnostic, neurocognitive and genetic data will also generate valuable information for future phenotypic and genetic studies of schizophrenia.

Low rates of treatment for hypertension, dyslipidemia and diabetes in schizophrenia: data from the CATIE schizophrenia trial sample at baseline.

UNLABELLED: Persons diagnosed with schizophrenia have higher morbidity and mortality rates from cardiovascular disease, yet often have limited access to appropriate primary care screening or treatment. Metabolic disorders such as diabetes, hyperlipidemia and hypertension are highly prevalent in populations with schizophrenia, exceeding 50% in some studies; however, there have been few published studies on treatment rates among schizophrenia patients screened for these disorders. METHODS: Using the baseline data from subjects (N=1460) recruited into the Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE) schizophrenia study, we examined the point prevalence of diabetes, hyperlipidemia and hypertension treatment at the time of enrollment for the entire cohort and those with fasting laboratory values obtained 8 or more hours since last meal. RESULTS: Rates of non-treatment ranged from 30.2% for diabetes, to 62.4% for hypertension, and 88.0% for dyslipidemia. Nonwhite men were more likely to be treated for DM and dyslipidemia than nonwhite women. CONCLUSIONS: These data indicate the high likelihood that metabolic disorders are untreated in patients with schizophrenia, with particularly high rates of non-treatment for hypertension and dyslipidemia. Nonwhite women may be especially vulnerable to undertreatment of dyslipidemia and diabetes compared to nonwhite men. The findings here support the need for increased attention to basic monitoring and treatment of cardiovascular risk factors in this vulnerable and often underserved psychiatric population.

Insight in first-episode psychosis.

BACKGROUND: We report here a study examining the relationships between insight and psychopathology, cognitive performance, brain volume and co-morbid depression in 251 patients experiencing a first episode of psychosis, who were then randomly assigned to 2 years of double-blind treatment with either olanzapine or haloperidol. METHOD: Repeated measures of insight were obtained at baseline and 12, 24, 52 and 104 weeks by the Insight and Treatment Attitudes Questionnaire (ITAQ). RESULTS: Older age, female gender and white ethnicity were associated with more insight. Higher total, positive, negative and general psychopathology scores on the Positive and Negative Syndromes Scale (PANSS) were associated with less insight. Higher depression scores were associated with more insight. Better neurocognitive function and large brain volumes were associated with more insight. More insight throughout the study was associated with longer time to medication non-adherence. However, baseline insight was not significantly related to the probability of discontinuing the study before 2 years. Insight improved significantly over the course of the study, but the improvement in insight was not significantly different between the two antipsychotic treatment groups. CONCLUSIONS: Multiple factors contribute to insight. Patients experiencing a first episode of psychosis who have little insight are at increased risk of discontinuing their medication.

Baseline neurocognitive deficits in the CATIE schizophrenia trial.

Neurocognition is moderately to severely impaired in patients with schizophrenia. However, the factor structure of the various neurocognitive deficits, the relationship with symptoms and other variables, and the minimum amount of testing required to determine an adequate composite score has not been determined in typical patients with schizophrenia. An 'all-comer' approach to cognition is needed, as provided by the baseline assessment of an unprecedented number of patients in the CATIE (Clinical Antipsychotic Trials of Intervention Effectiveness) schizophrenia trial. From academic sites and treatment providers representative of the community, 1493 patients with chronic schizophrenia were entered into the study, including those with medical comorbidity and substance abuse. Eleven neurocognitive tests were administered, resulting in 24 individual scores reduced to nine neurocognitive outcome measures, five domain scores and a composite score. Despite minimal screening procedures, 91.2% of patients provided meaningful neurocognitive data. Exploratory principal components analysis yielded one factor accounting for 45% of the test variance. Confirmatory factor analysis showed that a single-factor model comprised of five domain scores was the best fit. The correlations among the factors were medium to high, and scores on individual factors were very highly correlated with the single composite score. Neurocognitive deficits were modestly correlated with negative symptom severity (r=0.13-0.27), but correlations with positive symptom severity were near zero (r<0.08). Even in an 'all-comer' clinical trial, neurocognitive deficits can be assessed in the overwhelming majority of patients, and the severity of impairment is similar to meta-analytic estimates. Multiple analyses suggested that a broad cognitive deficit characterizes this sample. These deficits are modestly related to negative symptoms and essentially independent of positive symptom severity.

Predictors of antipsychotic medication adherence in patients recovering from a first psychotic episode.

BACKGROUND: Many patients recovering from a first psychotic episode will discontinue medication against medical advice, even before a 1-year treatment course is completed. Factors associated with treatment adherence in patients with chronic schizophrenia include beliefs about severity of illness and need for treatment, treatment with typical versus atypical antipsychotic and medication side effects. METHOD: In this 2-year prospective study of 254 patients recovering from a first episode of schizophrenia, schizophreniform, or schizoaffective disorder we examined the relationship between antipsychotic medication non-adherence and patient beliefs about: need for treatment, antipsychotic medication benefits, and negative aspects of antipsychotic medication treatment. We also examined the relationship between medication non-adherence and treatment with either haloperidol or olanzapine, and objective measures of symptom response and side effects. RESULTS: The likelihood of becoming medication non-adherent for 1 week or longer was greater in subjects whose belief in need for treatment was less (HR=1.75, 95% CI 1.16, 2.65, p=0.0077) or who believed medications were of low benefit (HR=2.88, 95 CI 1.79-4.65, p<0.0001). Subjects randomized to haloperidol were more likely to become medication non-adherent for >or=1 week than subjects randomized to olanzapine (HR-1.51, 95% CI 1.01, 2.27, p=0.045). CONCLUSION: Beliefs about need for treatment and the benefits of antipsychotic medication may be intervention targets to improve likelihood of long-term medication adherence in patients recovering from a first episode of schizophrenia, schizoaffective, or schizophreniform disorder.

A national study of violent behavior in persons with schizophrenia.

CONTEXT: Violent behavior is uncommon, yet problematic, among schizophrenia patients. The complex effects of clinical, interpersonal, and social-environmental risk factors for violence in this population are poorly understood. OBJECTIVE: To examine the prevalence and correlates of violence among schizophrenia patients living in the community by developing multivariable statistical models to assess the net effects of psychotic symptoms and other risk factors for minor and serious violence. DESIGN: A total of 1410 schizophrenia patients were clinically assessed and interviewed about violent behavior in the past 6 months. Data comprise baseline assessments of patients enrolled in the National Institute of Mental Health Clinical Antipsychotic Trials of Intervention Effectiveness. SETTING AND PATIENTS: Adult patients diagnosed as having schizophrenia were enrolled from 56 sites in the United States, including academic medical centers and community providers. MAIN OUTCOME MEASURES: Violence was classified at 2 severity levels: minor violence, corresponding to simple assault without injury or weapon use; and serious violence, corresponding to assault resulting in injury or involving use of a lethal weapon, threat with a lethal weapon in hand, or sexual assault. A composite measure of any violence was also analyzed. RESULTS: The 6-month prevalence of any violence was 19.1%, with 3.6% of participants reporting serious violent behavior. Distinct, but overlapping, sets of risk factors were associated with minor and serious violence. "Positive" psychotic symptoms, such as persecutory ideation, increased the risk of minor and serious violence, while "negative" psychotic symptoms, such as social withdrawal, lowered the risk of serious violence. Minor violence was associated with co-occurring substance abuse and interpersonal and social factors. Serious violence was associated with psychotic and depressive symptoms, childhood conduct problems, and victimization. CONCLUSIONS: Particular clusters of symptoms may increase or decrease violence risk in schizophrenia patients. Violence risk assessment and management in community-based treatment should focus on combinations of clinical and nonclinical risk factors.

Substance use in persons with schizophrenia: baseline prevalence and correlates from the NIMH CATIE study.

This study examined baseline correlates of substance use in the NIMH Clinical Antipsychotic Trials of Intervention Effectiveness project. Approximately 60% of the sample was found to use substances, including 37% with current evidence of substance use disorders. Users (with and without substance use disorders), compared with nonusers, were significantly more likely to be male, be African-American, have lower educational attainment, have a recent period of homelessness, report more childhood conduct problems, have a history of major depression, have lower negative symptom and higher positive symptom scores on the Positive and Negative Syndrome Scale, and have a recent illness exacerbation. Individuals with comorbid substance use disorders were significantly more likely to be male, report more childhood conduct problems, have higher positive symptom scores on the Positive and Negative Syndrome Scale, and have a recent illness exacerbation. These analyses suggest that substance use disorders in schizophrenia are especially common among men with a history of childhood conduct disorder problems and that childhood conduct disorder problems are potent risk factors for substance use disorders in schizophrenia.

Effectiveness of clozapine versus olanzapine, quetiapine, and risperidone in patients with chronic schizophrenia who did not respond to prior atypical antipsychotic treatment.

OBJECTIVE: When a schizophrenia patient has an inadequate response to treatment with an antipsychotic drug, it is unclear what other antipsychotic to switch to and when to use clozapine. In this study, the authors compared switching to clozapine with switching to another atypical antipsychotic in patients who had discontinued treatment with a newer atypical antipsychotic in the context of the Clinical Antipsychotic Trials for Interventions Effectiveness (CATIE) investigation. METHOD: Ninety-nine patients who discontinued treatment with olanzapine, quetiapine, risperidone, or ziprasidone in phase 1 or 1B of the trials, primarily because of inadequate efficacy, were randomly assigned to open-label treatment with clozapine (N=49) or blinded treatment with another newer atypical antipsychotic not previously received in the trial (olanzapine [N=19], quetiapine [N=15], or risperidone [N=16]). RESULTS: Time until treatment discontinuation for any reason was significantly longer for clozapine (median=10.5 months) than for quetiapine (median=3.3), or risperidone (median=2.8), but not for olanzapine (median=2.7). Time to discontinuation because of inadequate therapeutic effect was significantly longer for clozapine than for olanzapine, quetiapine, or risperidone. At 3-month assessments, Positive and Negative Syndrome Scale total scores had decreased more in patients treated with clozapine than in patients treated with quetiapine or risperidone but not olanzapine. One patient treated with clozapine developed agranulocytosis, and another developed eosinophilia; both required treatment discontinuation. CONCLUSIONS: For these patients with schizophrenia who prospectively failed to improve with an atypical antipsychotic, clozapine was more effective than switching to another newer atypical antipsychotic. Safety monitoring is necessary to detect and manage clozapine's serious side effects.

Effectiveness of olanzapine, quetiapine, risperidone, and ziprasidone in patients with chronic schizophrenia following discontinuation of a previous atypical antipsychotic.

BACKGROUND: In the treatment of schizophrenia, changing antipsychotics is common when one treatment is suboptimally effective, but the relative effectiveness of drugs used in this strategy is unknown. This randomized, double-blind study compared olanzapine, quetiapine, risperidone, and ziprasidone in patients who had just discontinued a different atypical antipsychotic. METHOD: Subjects with schizophrenia (N=444) who had discontinued the atypical antipsychotic randomly assigned during phase 1 of the Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE) investigation were randomly reassigned to double-blind treatment with a different antipsychotic (olanzapine, 7.5-30 mg/day [N=66]; quetiapine, 200-800 mg/day [N=63]; risperidone, 1.5-6.0 mg/day [N=69]; or ziprasidone, 40-160 mg/day [N=135]). The primary aim was to determine if there were differences between these four treatments in effectiveness measured by time until discontinuation for any reason. RESULTS: The time to treatment discontinuation was longer for patients treated with risperidone (median: 7.0 months) and olanzapine (6.3 months) than with quetiapine (4.0 months) and ziprasidone (2.8 months). Among patients who discontinued their previous antipsychotic because of inefficacy (N=184), olanzapine was more effective than quetiapine and ziprasidone, and risperidone was more effective than quetiapine. There were no significant differences between antipsychotics among those who discontinued their previous treatment because of intolerability (N=168). CONCLUSIONS: Among this group of patients with chronic schizophrenia who had just discontinued treatment with an atypical antipsychotic, risperidone and olanzapine were more effective than quetiapine and ziprasidone as reflected by longer time until discontinuation for any reason.

Interrelationships of psychiatric symptom severity, medical comorbidity, and functioning in schizophrenia.

OBJECTIVE: This cross-sectional study aimed to evaluate the interrelationships of psychiatric symptom severity, medical comorbidity, and psychosocial functioning in a sample of patients with schizophrenia by utilizing the baseline data from the Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE). METHODS: This study utilized baseline data from a multisite trial of antipsychotic pharmacotherapy, which collected data from 1,460 patients with schizophrenia at more than 50 sites in the United States between 2001 and 2003. Bivariate correlations were used to evaluate associations between schizophrenia symptoms and medical comorbidity, and multivariate regression models were used to determine the independent association between medical comorbidity and psychosocial functioning. RESULTS: Of the 1,424 participants in the study sample, 58 percent had at least one medical condition: 20 percent had hypertension, 11 percent had diabetes mellitus, and 9 percent had four or more medical conditions. Medical comorbidity was associated with poorer neurocognitive functioning and greater depressive symptoms. The number of medical conditions was not associated with more severe schizophrenia symptoms. Both the number of medical conditions and physical health status were only weak correlates of psychosocial functioning. CONCLUSIONS: In this sample of persons with schizophrenia, medical comorbidity was associated with depression and neurocognitive impairment but was a weaker correlate of psychosocial functioning or employment status than psychotic symptoms, depression, and neurocognitive impairment.

Substance use and psychosocial functioning in schizophrenia among new enrollees in the NIMH CATIE study.

OBJECTIVE: This study examined the relationship between substance use and psychosocial functioning in schizophrenia. METHODS: Participants were enrolled in the Clinical Antipsychotic Trials of Intervention Effectiveness. This study used baseline assessments and examined psychosocial functioning assessed by the Quality of Life Scale. Participants were classified as being abstinent, using substances, or having a substance use disorder. RESULTS: Of the 1,460 participants, 23 percent used substances and 37 percent had a substance use disorder. Of the 544 with a substance use disorder, 87 percent used alcohol, 44 percent used marijuana, and 36 percent used cocaine. Compared with participants who used substances, those with a substance use disorder had higher rates of polysubstance use. Compared with those who were abstinent, those who used substances had higher overall psychosocial functioning, and those with a substance use disorder had similar overall functioning but lower scores on the common objects and activities subscales. Among participants with a substance use disorder, those who used cocaine had lower overall functioning. CONCLUSIONS: Compared with abstinence, substance use and substance use disorder, unless they involved cocaine use, were generally associated with higher or equivalent overall psychosocial functioning. Patterns of substance use were similar to those in the community, suggesting that treatment of substance use disorders in schizophrenia should focus on reconnecting substance users to nonusing peer groups.

Risks versus benefits of different types of long-acting injectable antipsychotics.

Since their introduction into clinical practice in the early 1960s, long-acting depot antipsychotics have been widely used as maintenance therapy for patients with schizophrenia. The improved pharmacokinetics of injectable long-acting antipsychotic therapies have provided more reliable drug delivery and reduced differences in peak and trough plasma levels of the drug. Studies that have compared short-acting oral antipsychotics with long-acting injectable antipsychotics, although imperfect, support injectable antipsychotics as having real benefit over oral antipsychotics on patient outcome owing largely to improved adherence. If patients forget or refuse to take their prescribed oral medications, weeks or months may go by before they experience an exacerbation; the effects of nonadherence become apparent too late to preempt the problem. On the other hand, if a patient fails to show up for an injection, the problem of nonadherence can be immediately addressed. When injectable medication is combined with an active psychosocial treatment program that will respond assertively to nonadherence, relapse rates may be reduced. By preventing or delaying relapse, consistent treatment can improve the patient's quality of life and lead to an overall reduction in the cost of care.

Striatal dopamine D2/D3 receptor availability in male smokers.

It has been reported that the activation of the nicotine receptor evokes central endogenous dopamine release. However, whether smoking affects striatal dopamine D(2)/D(3) availability over the long run has not been well established in vivo. Fifteen male smokers and their matching controls were recruited. Striatal dopamine D(2)/D(3) receptor availability was assessed by single photon emission computed tomography with [(123)]IBZM Iodo-benzaimide. There was no significant difference in striatal D(2)/D(3) receptor availability between smokers and controls.

A comparison of ten-year cardiac risk estimates in schizophrenia patients from the CATIE study and matched controls.

OBJECTIVE: Standardized mortality rates are elevated in schizophrenia compared to the general population. The incidence of coronary heart disease (CHD) and the relative contribution of CHD to increased mortality in schizophrenia patients are not clear, despite recent concerns about metabolic complications of certain atypical antipsychotics. METHOD: Ten-year risk for CHD was calculated for 689 subjects who participated in the Clinical Trials of Antipsychotic Treatment Effectiveness (CATIE) Schizophrenia Trial at baseline using the Framingham CHD risk function and were compared with age-, race- and gender-matched controls from the National Health and Nutrition Examination Survey (NHANES) III. RESULTS: Ten-year CHD risk was significantly elevated in male (9.4% vs. 7.0%) and female (6.3% vs. 4.2%) schizophrenia patients compared to controls (p = 0.0001). Schizophrenia patients had significantly higher rates of smoking (68% vs. 35%), diabetes (13% vs. 3%), and hypertension (27% vs. 17%) and lower HDL cholesterol levels (43.7 vs. 49.3 mg/dl) compared to controls (p < 0.001). Only total cholesterol levels did not differ between groups. Ten-year CHD risk remained significantly elevated in schizophrenia patients after controlling for body mass index (p = 0.0001). CONCLUSIONS: These results are consistent with recent evidence of increased cardiac mortality in schizophrenia patients. While the impact of cigarette smoking is clear, the relative contributions to cardiac risk of specific antipsychotic agents, diet, exercise, and quality of medical care remain to be clarified.

Clinical correlates of tardive dyskinesia in schizophrenia: baseline data from the CATIE schizophrenia trial.

OBJECTIVE: To examine the clinical characteristics of individuals with schizophrenia that develop tardive dyskinesia (TD) associated with antipsychotic treatment. METHODS: Baseline data on 1460 patients with schizophrenia were collected as part of the Clinical Antipsychotic Trials of Intervention Effectiveness schizophrenia study. Subjects who met Schooler-Kane criteria for probable TD were compared to those without TD. Multiple regression analyses were used to examine the relationship between TD and clinical variables. RESULTS: 212 subjects met the Schooler-Kane criteria for probable TD and 1098 had no history or current evidence of TD. Subjects with TD were older, had a longer duration of receiving antipsychotic medication, and were more likely to have been receiving a conventional antipsychotic and an anticholinergic agent. After controlling for important baseline covariates, diabetes mellitus (DM) and hypertension did not predict TD, whereas substance abuse significantly predicted TD. Differences in cognitive functioning were not significantly different after controlling for baseline covariates. The TD subjects also had higher ratings of psychopathology, EPSE, and akathisia. CONCLUSION: Our results confirm the established relationships between the presence of TD and age, duration of treatment with antipsychotics, treatment with a conventional antipsychotic, treatment with anticholinergics, the presence of EPS and akathisia, and substance abuse. Subjects with TD had higher ratings of psychopathology as measured by the PANSS. We found no support for DM or hypertension increasing the risk of TD, or for TD being associated with cognitive impairment.

Effectiveness of antipsychotic drugs in patients with chronic schizophrenia.

BACKGROUND: The relative effectiveness of second-generation (atypical) antipsychotic drugs as compared with that of older agents has been incompletely addressed, though newer agents are currently used far more commonly. We compared a first-generation antipsychotic, perphenazine, with several newer drugs in a double-blind study. METHODS: A total of 1493 patients with schizophrenia were recruited at 57 U.S. sites and randomly assigned to receive olanzapine (7.5 to 30 mg per day), perphenazine (8 to 32 mg per day), quetiapine (200 to 800 mg per day), or risperidone (1.5 to 6.0 mg per day) for up to 18 months. Ziprasidone (40 to 160 mg per day) was included after its approval by the Food and Drug Administration. The primary aim was to delineate differences in the overall effectiveness of these five treatments. RESULTS: Overall, 74 percent of patients discontinued the study medication before 18 months (1061 of the 1432 patients who received at least one dose): 64 percent of those assigned to olanzapine, 75 percent of those assigned to perphenazine, 82 percent of those assigned to quetiapine, 74 percent of those assigned to risperidone, and 79 percent of those assigned to ziprasidone. The time to the discontinuation of treatment for any cause was significantly longer in the olanzapine group than in the quetiapine (P<0.001) or risperidone (P=0.002) group, but not in the perphenazine (P=0.021) or ziprasidone (P=0.028) group. The times to discontinuation because of intolerable side effects were similar among the groups, but the rates differed (P=0.04); olanzapine was associated with more discontinuation for weight gain or metabolic effects, and perphenazine was associated with more discontinuation for extrapyramidal effects. CONCLUSIONS: The majority of patients in each group discontinued their assigned treatment owing to inefficacy or intolerable side effects or for other reasons. Olanzapine was the most effective in terms of the rates of discontinuation, and the efficacy of the conventional antipsychotic agent perphenazine appeared similar to that of quetiapine, risperidone, and ziprasidone. Olanzapine was associated with greater weight gain and increases in measures of glucose and lipid metabolism.

Prevalence of the metabolic syndrome in patients with schizophrenia: baseline results from the Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE) schizophrenia trial and comparison with national estimates from NHANES III.

UNLABELLED: One important risk factor for cardiovascular disease is the metabolic syndrome (MS), yet limited data exist on its prevalence in US patients with schizophrenia. METHODS: Using baseline data from the Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE) Schizophrenia Trial, assessment of MS prevalence was performed based on National Cholesterol Education Program (NCEP) criteria, and also using a fasting glucose threshold of 100 mg/dl (AHA). Subjects with sufficient anthropometric data, data on use of antihypertensives, hypoglycemic medications or insulin, and fasting glucose and lipid values >8 h from last meal were included in the analysis. Comparative analyses were performed using a randomly selected sample from NHANES III matched 1:1 on the basis of age, gender and race/ethnicity. RESULTS: Of 1460 CATIE baseline subjects, 689 met analysis criteria. MS prevalence was 40.9% and 42.7%, respectively using the NCEP and AHA derived criteria. In females it was 51.6% and 54.2% using the NCEP and AHA criteria, compared to 36.0% (p = .0002) and 36.6% (p = .0003), respectively for males. 73.4% of all females (including nonfasting subjects) met the waist circumference criterion compared to 36.6% of males. In a logistic regression model with age, race and ethnicity as covariates, CATIE males were 138% more likely to have MS than the NHANES matched sample, and CATIE females 251% more likely than their NHANES counterparts. Even when controlling for differences in body mass index, CATIE males were still 85% more likely to have MS than the NHANES male sample, and CATIE females 137% more likely to have MS than females in NHANES. CONCLUSIONS: The metabolic syndrome is highly prevalent in US schizophrenia patients and represents an enormous source of cardiovascular risk, especially for women. Clinical attention must be given to monitoring for this syndrome, and minimizing metabolic risks associated with antipsychotic treatment.
