  • A Study to Compare Disease Progression and Modification Following Treatment With Paliperidone Palmitate Long-Acting Injection or Oral Antipsychotics in Participant's With Recent-onset Schizophrenia or Schizophreniform Not Recruiting

    The purpose of the study is to compare effectiveness of paliperidone palmitate (PP: paliperidone palmitate once-monthly and 3-month injections) versus oral antipsychotic (OAP [that is oral paliperidone extended release {ER}, oral risperidone, or another OAP]) in delaying time to treatment failure. The study will also evaluate changes in cognition, functioning, brain intracortical myelin (ICM) volume following treatment with PP compared with OAP in participants with recent-onset schizophrenia or schizophreniform disorder.

    Stanford is currently not accepting patients for this trial.

  • Clozapine Titration for People in Early Psychosis A Chart Review and Treatment Guideline JOURNAL OF CLINICAL PSYCHOPHARMACOLOGY Ballon, J. S., Ashfaq, H., Noordsy, D. L. 2018; 38 (3): 234–38

    Abstract

    The use of clozapine, particularly in young people, is often limited by early treatment-emergent adverse effects including drowsiness and lethargy. Concerns about adverse effects, medication adherence, and the need for blood monitoring often impede the use of clozapine in this population, leading to repeated trials of less effective medications. Current clozapine dosing recommendations are based on people further in the course of their illness and thus reflect different responsiveness and sensitivities to antipsychotic medication. As such, there is a need for evidence-based guidelines for titration and dosing of clozapine among people in early psychosis.We performed a chart review of 14 people treated with clozapine within our early psychosis team. Data regarding dose titration, response, time to discontinuation, symptom severity, weight gain, and other adverse effects were gathered at clozapine initiation, 3 months, and last available visit on clozapine.People treated with slow titration within their first year of psychosis onset achieved sustained response at very low maintenance doses (mean dose = 81 mg/d, mean duration of treatment = 200 weeks) compared with slow titration with longer duration of illness (mean dose = 350 mg/d, mean duration of treatment = 68 weeks) or standard dose titration in early psychosis (mean dose = 112 mg/d, mean duration of treatment = 38 weeks). The most common adverse effects in all groups were weight gain and sedation, with the groups requiring higher mean doses reporting a broader range of adverse effects. There was no apparent difference in the clinical global impression for severity or improvement between the slow titration and standard titration groups in people with early psychosis. These observations are synthesized into a proposed treatment guideline for use of clozapine among people in early psychosis.We describe development of a slow titration approach to initiating clozapine among people in early psychosis. This approach resulted in clinical response at remarkably low maintenance doses of clozapine among people within their first year of illness, but not in those with longer duration of symptoms. Slow titration also led to good tolerability and acceptance of clozapine treatment for some patients.

  • Impact of age of onset of psychosis and engagement in higher education on duration of untreated psychosis JOURNAL OF MENTAL HEALTH Hardy, K. V., Noordsy, D. L., Ballon, J. S., McGovern, M. P., Salomon, C., Stirman, S. 2018; 27 (3): 257–62

    Abstract

    The average age of onset of psychosis coincides with the age of college enrollment. Little is known about the impact of educational engagement on DUP in a college-aged population.To determine DUP, and the impact of educational engagement, for college-aged participants of the RAISE study (n = 404).We conducted secondary data analyses on the publicly available RAISE dataset. Subsamples were analyzed to determine the impact of age and educational engagement on DUP.DUP was significantly shorter (p < 0.02) for participants who were college-aged (18-22 years, n = 44) and engaged in post-secondary education (median = 12 weeks, mean = 29 weeks) compared with participants who were college-aged and not engaged in higher education (n = 92, median = 29 weeks, mean = 44 weeks).Educational engagement appears to be associated with a shorter DUP. This may be partially explained by the presence of on-site wellness centers in college settings. However, even among young people who engaged in post-secondary education DUP was still at, or beyond, the upper limit of WHO recommendations in this group. Future research exploring how colleges could improve their capacity to detect and refer at risk students for treatment at an earlier stage is recommended.

  • Genetic Correlation Profile of Schizophrenia Mirrors Epidemiological Results and Suggests Link Between Polygenic and Rare Variant (22q11.2) Cases of Schizophrenia. Schizophrenia bulletin Duncan, L. E., Shen, H., Ballon, J. S., Hardy, K. V., Noordsy, D. L., Levinson, D. F. 2017

    Abstract

    New methods in genetics research, such as linkage disequilibrium score regression (LDSR), quantify overlap in the common genetic variants that influence diverse phenotypes. It is becoming clear that genetic effects often cut across traditional diagnostic boundaries. Here, we introduce genetic correlation analysis (using LDSR) to a nongeneticist audience and report transdisciplinary discoveries about schizophrenia. This analytical study design used publically available genome wide association study (GWAS) data from approximately 1.5 million individuals. Genetic correlations between schizophrenia and 172 medical, psychiatric, personality, and metabolomic phenotypes were calculated using LDSR, as implemented in LDHub in order to identify known and new genetic correlations. Consistent with previous research, the strongest genetic correlation was with bipolar disorder. Positive genetic correlations were also found between schizophrenia and all other psychiatric phenotypes tested, the personality traits of neuroticism and openness to experience, and cigarette smoking. Novel results were found with medical phenotypes: schizophrenia was negatively genetically correlated with serum citrate, positively correlated with inflammatory bowel disease, and negatively correlated with BMI, hip, and waist circumference. The serum citrate finding provides a potential link between rare cases of schizophrenia (strongly influenced by 22q11.2 deletions) and more typical cases of schizophrenia (with polygenic influences). Overall, these genetic correlation findings match epidemiological findings, suggesting that common variant genetic effects are part of the scaffolding underlying phenotypic comorbidity. The "genetic correlation profile" is a succinct report of shared genetic effects, is easily updated with new information (eg, from future GWAS), and should become part of basic disease knowledge about schizophrenia.

  • Use of Active-Play Video Games to Enhance Aerobic Fitness in Schizophrenia: Feasibility, Safety, and Adherence PSYCHIATRIC SERVICES Kimhy, D., Khan, S., Ayanrouh, L., Chang, R. W., Hansen, M. C., Lister, A., Ballon, J. S., Vakhrusheva, J., Armstrong, H. F., Bartels, M. N., Sloan, R. P. 2016; 67 (2): 240-243

    Abstract

    Active-play video games have been used to enhance aerobic fitness in various clinical populations, but their use among individuals with schizophrenia has been limited.Feasibility, acceptability, safety, and adherence data were obtained for use of aerobic exercise (AE) equipment by 16 individuals with schizophrenia during a 12-week AE program consisting of three one-hour exercise sessions per week. Equipment included exercise video games for Xbox 360 with Kinect motion sensing devices and traditional exercise equipment.Most participants (81%) completed the training, attending an average of 79% of sessions. The proportion of time spent playing Xbox (39%) exceeded time spent on any other type of equipment. When using Xbox, participants played 2.24±1.59 games per session and reported high acceptability and enjoyment ratings, with no adverse events.Measures of feasibility, acceptability, adherence, and safety support the integration of active-play video games into AE training for people with schizophrenia.

  • The Impact of Aerobic Exercise on Brain-Derived Neurotrophic Factor and Neurocognition in Individuals With Schizophrenia: A Single-Blind, Randomized Clinical Trial SCHIZOPHRENIA BULLETIN Kimhy, D., Vakhrusheva, J., Bartels, M. N., Armstrong, H. F., Ballon, J. S., Khan, S., Chang, R. W., Hansen, M. C., Ayanruoh, L., Lister, A., Castren, E., Smith, E. E., Sloan, R. P. 2015; 41 (4): 859-868

    Abstract

    Individuals with schizophrenia display substantial neurocognitive deficits for which available treatments offer only limited benefits. Yet, findings from studies of animals, clinical and nonclinical populations have linked neurocognitive improvements to increases in aerobic fitness (AF) via aerobic exercise training (AE). Such improvements have been attributed to up-regulation of brain-derived neurotrophic factor (BDNF). However, the impact of AE on neurocognition, and the putative role of BDNF, have not been investigated in schizophrenia. Employing a proof-of-concept, single-blind, randomized clinical trial design, 33 individuals with schizophrenia were randomized to receive standard psychiatric treatment (n = 17; "treatment as usual"; TAU) or attend a 12-week AE program (n = 16) utilizing active-play video games (Xbox 360 Kinect) and traditional AE equipment. Participants completed assessments of AF (indexed by VO2 peak ml/kg/min), neurocognition (MATRICS Consensus Cognitive Battery), and serum-BDNF before and after and 12-week period. Twenty-six participants (79%) completed the study. At follow-up, the AE participants improved their AF by 18.0% vs a -0.5% decline in the TAU group (P = .002) and improved their neurocognition by 15.1% vs -2.0% decline in the TAU group (P = .031). Hierarchical multiple regression analyses indicated that enhancement in AF and increases in BDNF predicted 25.4% and 14.6% of the neurocognitive improvement variance, respectively. The results indicate AE is effective in enhancing neurocognitive functioning in people with schizophrenia and provide preliminary support for the impact of AE-related BDNF up-regulation on neurocognition in this population. Poor AF represents a modifiable risk factor for neurocognitive dysfunction in schizophrenia for which AE training offer a safe, nonstigmatizing, and side-effect-free intervention.

  • Aerobic fitness and body mass index in individuals with schizophrenia: Implications for neurocognition and daily functioning PSYCHIATRY RESEARCH Kimhy, D., Vakhrusheva, J., Bartels, M. N., Armstrong, H. E., Ballon, J. S., Khan, S., Chang, R. W., Hansen, M. C., Ayanruoh, L., Smith, E. E., Sloan, R. P. 2014; 220 (3): 784-791

    Abstract

    Previous reports indicate that among healthy individuals low aerobic fitness (AF) and high body-mass index (BMI) predict poor neurocognition and daily-functioning. It is unknown whether these associations extend to disorders characterized by poor neurocognition, such as schizophrenia. Therefore, we compared AF and BMI in individuals with schizophrenia and non-clinical controls, and then within the schizophrenia group we examined the links between AF, BMI, neurocognition and daily-functioning. Thirty-two individuals with schizophrenia and 64 gender- and age-matched controls completed assessments of AF (indexed by VO2max) and BMI. The former also completed measures of neurocognition, daily-functioning and physical activity. The schizophrenia group displayed significantly lower AF and higher BMI. In the schizophrenia group, AF was significantly correlated with overall neurocognition (r=0.57), along with executive functioning, working memory, social cognition, and processing speed. A hierarchical regression analysis indicated that AF accounted for 22% of the neurocognition variance. Furthermore, AF was significantly correlated with overall daily-functioning (r=0.46). In contrast, BMI displayed significant inverse correlations with neurocognition, but no associations to daily-functioning. AF was significantly correlated physical activity. The authors discuss the potential use of AF-enhancing interventions to improve neurocognitive and daily-functioning in schizophrenia, along with putative neurobiological mechanisms underlying these links, including Brain-Derived Neurotrophic Factor.

  • Molecular pathophysiology of metabolic effects of antipsychotic medications TRENDS IN ENDOCRINOLOGY AND METABOLISM Ballon, J. S., Pajvani, U., Freyberg, Z., Leibel, R. L., Lieberman, J. A. 2014; 25 (11): 593-600

    Abstract

    Antipsychotic medications are associated with major metabolic changes that contribute to medical morbidity and a significantly shortened life span. The mechanisms for these changes provide us with a broader understanding of central nervous and peripheral organ-mediated metabolic regulation. This paper reviews an extensive literature regarding putative mechanisms for effects of antipsychotic medications on weight regulation and glucose homeostasis as well as potential inherent metabolic risks of schizophrenia itself. We present a model suggesting that peripheral antipsychotic targets play a critical role in drug-induced weight gain and diabetes. We propose that a better understanding of these mechanisms will be crucial to developing improved treatments for serious mental illnesses as well as providing potentially novel therapeutic targets of metabolic disorders including diabetes.

  • Emotional granularity and social functioning in individuals with schizophrenia: An experience sampling study JOURNAL OF PSYCHIATRIC RESEARCH Kimhy, D., Vakhrusheva, J., Khan, S., Chang, R. W., Hansen, M. C., Ballon, J. S., Malaspina, D., Gross, J. J. 2014; 53: 141-148

    Abstract

    Previous research has shown that healthy individuals who fail to differentiate among emotional states (i.e., those with low emotional granularity; EG) have poorer social functioning (SF) than those with high EG. It is unknown, however, whether these associations extend to clinical disorders characterized by impaired SF, such as schizophrenia. In the present study, we compared SF and EG in individuals with schizophrenia and healthy controls, and then, within the schizophrenia group, we examined the links between EG and SF. Employing an Experience Sampling Method approach, 77 individuals with schizophrenia and 27 healthy controls rated their momentary emotions (sadness, anxiety, anger, and happiness) up to 10 times/day over a two-day period using mobile electronic devices. For each participant, we then calculated the within-subject average correlations among the momentary emotion ratings, producing two EG indices - EGIall for all emotions and EGIneg for negative ones. A subsample of participants with schizophrenia also completed self-report, interview, and ability-based measures of SF. Compared to healthy controls, individuals with schizophrenia displayed significantly poorer SF and lower EGIall, but comparable EGIneg. Within the schizophrenia group, hierarchical multiple regression analyses indicated that EGIall, but not EGIneg, significantly predicted social dysfunction after controlling for emotional awareness, symptoms, and emotional intensity and variability. Our findings indicate that individuals with schizophrenia have a relatively intact ability to differentiate among negative emotions in everyday life. However, they experience significant difficulties differentiating between positive and negative emotions, and this may contribute to their social difficulties.

  • Polypharmacy for schizophrenia CURRENT OPINION IN PSYCHIATRY Ballon, J., Stroup, T. S. 2013; 26 (2): 208-213

    Abstract

    Combining psychotropic medications is common for people diagnosed with schizophrenia facing a variety of clinical circumstances. This review provides an update on evidence regarding the effectiveness of polypharmacy approaches.Epidemiology studies have demonstrated that polypharmacy is extremely common, but evidence regarding all polypharmacy approaches for schizophrenia from randomized controlled trials remains scarce. Combinations of antipsychotic medicines are unsupported by evidence. Antidepressants are commonly used to treat depressive symptoms; this logical role for antidepressants has little support from randomized controlled trials (RCTs) but may be associated with lower suicide and all-cause mortality. Insufficient evidence supports the use of benzodiazepines for schizophrenia; possible risks of benzodiazepines, including increased mortality rates revealed in observational studies, warrant caution and further study.The lack of evidence regarding common treatment strategies exacerbates the tremendous challenge of providing optimal pharmacotherapy for individuals with schizophrenia. Comparative effectiveness research, using observational methods when appropriate and RCTs when possible, is needed to inform clinical practice, use resources wisely and improve outcomes.

  • Signaling pathways in schizophrenia: emerging targets and therapeutic strategies TRENDS IN PHARMACOLOGICAL SCIENCES Karam, C. S., Ballon, J. S., Bivens, N. M., Freyberg, Z., GirgiS, R. R., Lizardi-Ortiz, J. E., Markx, S., Lieberman, J. A., Javitch, J. A. 2010; 31 (8): 381-390

    Abstract

    Dopamine D(2) receptor antagonism is a unifying property of all antipsychotic drugs in use for schizophrenia. While often effective at ameliorating psychosis, these drugs are largely ineffective at treating negative and cognitive symptoms. Increasing attention is being focused on the complex genetics of the illness and the signaling pathways implicated in its pathophysiology. We review targeted approaches for pharmacotherapy involving the glutamatergic, GABAergic and cholinergic pathways. We also describe several of the major genetic findings that identify signaling pathways representing potential targets for novel pharmacological intervention. These include genes in the 22q11 locus, DISC1, Neuregulin 1/ErbB4, and components of the Akt/GSK-3 pathway.

  • Teaching Pearls from the Lost Art of Psychopharmacology JOURNAL OF PSYCHIATRIC PRACTICE Glick, I. D., Balon, R. J., Ballon, J., Rovine, D. 2009; 15 (5): 423-426

    Abstract

    Rapid advances in neuroscience and clinical research have made the practice of quality clinical psychopharmacology increasingly difficult. While practice guidelines, model psychopharmacology curricula, and clinical algorithms have helped "the science" of psychopharmacology, they often fail to provide guidance for clinicians in specific clinical situations with individual patients. Quality psychopharmacology practice is based on a combination of knowledge, experience, judgment, and luck. In this article, the authors present their collection of psychopharmacology "pearls" for trainees as well as experienced clinicians. (Journal of Psychiatric Practice 2009;15:423-426).

  • Social functioning in young people at risk for schizophrenia 60th Annual Convention of the Society-of-Biological-Psychiatry Ballon, J. S., Kaur, T., Marks, I. I., Cadenhead, K. S. ELSEVIER IRELAND LTD. 2007: 29–35

    Abstract

    Deficits in social functioning are potential risk factors for schizophrenia. Social functioning was assessed in 55 individuals "at risk" for schizophrenia, 16 first episode patients with schizophrenia and 45 normal comparison subjects. The Social Adjustment Inventory for Children and Adolescents (SAICA) was administered to adolescents <18 and the Social Adjustment Scale (SAS-SR) to young adults >17. The at risk and first episode groups significantly differed from the normal subjects on measures of social functioning in the domains of peer, family, work and school relationships. Individuals at risk for schizophrenia have significant functional deficits which may be potential indicators of increased vulnerability for psychosis.

  • A systematic review of modafinil: Potential clinical uses and mechanisms of action JOURNAL OF CLINICAL PSYCHIATRY Ballon, J. S., Feifel, D. 2006; 67 (4): 554-566

    Abstract

    Modafinil is a novel wake-promoting agent that has U.S. Food and Drug Administration approval for narcolepsy and shift work sleep disorder and as adjunctive treatment of obstructive sleep apnea/hypopnea syndrome. Modafinil has a novel mechanism and is theorized to work in a localized manner, utilizing hypocretin, histamine, epinephrine, gamma-aminobutyric acid, and glutamate. It is a well-tolerated medication with low propensity for abuse and is frequently used for off-label indications. The objective of this study was to systematically review the available evidence supporting the clinical use of modafinil.The search term modafinil OR Provigil was searched on PubMed. Selected articles were mined for further potential sources of data. Abstracts from major scientific conferences were reviewed. Lastly, the manufacturer of modafinil in the United States was asked to provide all publications, abstracts, and unpublished data regarding studies of modafinil.There have been 33 double-blind, placebo-controlled trials of modafinil. Additionally, numerous smaller studies have been performed, and case reports of modafinil's use abound in the literature.Modafinil is a promising drug with a large potential for many uses in psychiatry and general medicine. Treating daytime sleepiness is complex, and determining the precise nature of the sleep disorder is vital. Modafinil may be an effective agent in many sleep conditions. To date, the strongest evidence among off-label uses exists for the use of modafinil in attention-deficit disorder, postanesthetic sedation, and cocaine dependence and withdrawal and as an adjunct to antidepressants for depression.

  • The effects of novel antipsychotics on glucose and lipid levels JOURNAL OF CLINICAL PSYCHIATRY Wirshing, D. A., Boyd, J. A., Meng, L. R., Ballon, J. S., Marder, S. R., Wirshing, W. C. 2002; 63 (10): 856-865

    Abstract

    The novel antipsychotics are extensively used based on their favorable extrapyramidal side effect profiles. However, accumulating evidence suggests that these agents, particularly clozapine and olanzapine, have serious side effects of their own, including weight gain and elevated glucose and triglyceride levels. The goal of this study is to compare the effects of novel antipsychotics clozapine, olanzapine, risperidone, and quetiapine and typical antipsychotics haloperidol and fluphenazine on glucose and lipid levels.The charts of 590 patients were retrospectively reviewed. Of those, 215 patients had adequate laboratory data for inclusion. Glucose and lipid level data from 2 1/2 years before and after initiation of the target antipsychotic were included. Covariates, including patients' age, the duration of antipsychotic treatment, other medications that may affect glucose or lipid levels, and the initial laboratory values, were controlled for in the analyses.Glucose levels were increased from baseline for patients treated with clozapine, olanzapine, and haloperidol. There were statistically and clinically significant differences among the medications' effects on lipid profiles (p < .05). Those receiving clozapine and olanzapine demonstrated statistically significant increases in triglyceride levels compared with the other groups. Over one third of patients treated with any of the novel antipsychotics had clinically meaningful triglyceride elevations.It has been shown that novel antipsychotics are associated with weight gain. This risk factor along with others, such as elevated glucose and triglyceride levels, compounds the risk for coronary artery disease. Routine monitoring of glucose and lipid levels during treatment with novel antipsychotics should be advocated.
