Diagnostic model development for schizophrenia based on peripheral blood mononuclear cell subtype-specific expression of metabolic markers

A significant proportion of the personal and economic burden of schizophrenia can be attributed to the late diagnosis or misdiagnosis of the disorder. A novel, objective diagnostic approaches could facilitate the early detection and treatment of schizophrenia and improve patient outcomes. In the present study, we aimed to identify robust schizophrenia-specific blood biomarkers, with the goal of developing an accurate diagnostic model. The levels of selected serum and peripheral blood mononuclear cell (PBMC) markers relevant to metabolic and immune function were measured in healthy controls (n = 26) and recent-onset schizophrenia patients (n = 36) using multiplexed immunoassays and flow cytometry. Analysis of covariance revealed significant upregulation of insulin receptor (IR) and fatty acid translocase (CD36) levels in T helper cells (F = 10.75, P = 0.002, Q = 0.024 and F = 21.58, P = 2.8 × 10−5, Q = 0.0004, respectively), as well as downregulation of glucose transporter 1 (GLUT1) expression in monocytes (F = 21.46, P = 2.9 × 10−5, Q = 0.0004). The most robust predictors, monocyte GLUT1 and T helper cell CD36, were used to develop a diagnostic model, which showed a leave-one-out cross-validated area under the receiver operating characteristic curve (AUC) of 0.78 (95% CI: 0.66–0.92). The diagnostic model was validated in two independent datasets. The model was able to distinguish first-onset, drug-naïve schizophrenia patients (n = 34) from healthy controls (n = 39) with an AUC of 0.75 (95% CI: 0.64–0.86), and also differentiated schizophrenia patients (n = 22) from patients with other neuropsychiatric conditions, including bipolar disorder, major depressive disorder and autism spectrum disorder (n = 68), with an AUC of 0.83 (95% CI: 0.75–0.92). These findings indicate that PBMC-derived biomarkers have the potential to support an accurate and objective differential diagnosis of schizophrenia.

The Economic Burden of Schizophrenia in the United States.

Aim: The economic burden of schizophrenia in the United States (US) was estimated at $155.7 billion in 2013. Since 2013, the US experienced significant health care reforms and treatment advances. This study analyzed recent data and literature to update the US economic burden estimate for schizophrenia.Methods: Direct and indirect costs associated with schizophrenia were estimated using a prevalence-based approach. Direct health care costs were assessed retrospectively using an exact matched cohort design in the IBM Watson Health MarketScan databases from October 1, 2015, through December 31, 2019. Patients with schizophrenia (identified using ICD-10-CM codes F20 and F25) were exactly matched to controls on demographics, insurance type, and index year. Direct non-health care costs were estimated using published literature and government data. Indirect costs were estimated using a human capital approach and the value of quality-adjusted life-years lost. Cost offsets were estimated to account for basic living costs avoided. Excess costs, comparing costs for individuals with and without schizophrenia, were reported in 2019 USD.Results: The estimated excess economic burden of schizophrenia in the US in 2019 was $343.2 billion, including $251.9 billion in indirect costs (73.4%), $62.3 billion in direct health care costs (18.2%), and $35.0 billion in direct non-health care costs (10.2%). The largest drivers of indirect costs were caregiving ($112.3 billion), premature mortality ($77.9 billion), and unemployment ($54.2 billion). Cost offsets, representing $6.0 billion (1.7%), were subtracted from direct non-health care costs.Conclusions: The estimated burden of schizophrenia in the US doubled between 2013 and 2019 and was $343.2 billion in 2019, highlighting the importance of effective strategies and treatment options to improve the management of this difficult-to-treat patient population.

MDMA for the Treatment of Negative Symptoms in Schizophrenia.

The profound economic burden of schizophrenia is due, in part, to the negative symptoms of the disease, which can severely limit daily functioning. There is much debate in the field regarding their measurement and classification and there are no FDA-approved treatments for negative symptoms despite an abundance of research. 3,4-Methylenedioxy methamphetamine (MDMA) is a schedule I substance that has emerged as a novel therapeutic given its ability to enhance social interactions, generate empathy, and induce a state of metaplasticity in the brain. This review provides a rationale for the use of MDMA in the treatment of negative symptoms by reviewing the literature on negative symptoms, their treatment, MDMA, and MDMA-assisted therapy. It reviews recent evidence that supports the safe and potentially effective use of MDMA to treat negative symptoms and concludes with considerations regarding safety and possible mechanisms of action.

Prevalence, incidence and economic burden of schizophrenia among Medicaid beneficiaries

Objective To estimate the prevalence, incidence and economic burden of schizophrenia among Medicaid beneficiaries. Methods Annual prevalence and incidence of schizophrenia among adult Medicaid beneficiaries were estimated during 2012–2017, by state and across six states (IA, KS, MS, MO, NJ and WI). The pooled estimate of the economic burden of schizophrenia was obtained during 1998Q1–2018Q1 across six states; adults with ≥2 diagnoses of schizophrenia were matched 1:1 to schizophrenia-free controls. The last observed schizophrenia diagnosis (schizophrenia cohort) or the last service claim (control cohort) with ≥12 months of continuous Medicaid enrollment before/after it defined the index date. Healthcare resource utilization (HRU) and costs ($2018 USD) incurred 12 months post-index were compared between cohorts. The economic burden of schizophrenia was also evaluated among young adults (18–34 years). Results Annual prevalence of schizophrenia ranged between 2.30% and 2.71% and annual incidence between 0.31% and 0.39% during 2012–2016. In 2017, only states with the highest incidence and prevalence rates (KS, MS, MO) had data, resulting in higher prevalence (4.01%) and incidence (0.52%). For the economic burden, adults with schizophrenia (N = 158,763) had higher HRU and incurred $14,087 higher healthcare costs versus controls (mean: $28,644 vs. $14,557), driven by $4677 higher long-term care costs (all p < .001). Young adults with schizophrenia incurred $14,945 higher healthcare costs versus controls, driven by $3473 higher inpatient costs (p < 0.001). Conclusions Annual prevalence and incidence of schizophrenia varied by state but remained stable over time. Adults with schizophrenia incurred greater HRU and costs relative to adults without schizophrenia; the burden appeared comparable among young adults.

A closer look at the epidemiology of schizophrenia and common mental disorders in Brazil

ABSTRACT.Schizophrenia and common mental disorders are noteworthy social and economic concern worldwide. Epidemiologic studies on the impact of specific mental disorders in emerging countries are scarce.Objectives: We aimed to characterize the demographic, social, and economic burden of schizophrenia and common mental disorders patients in the health system in Brazil.Methods: Data on these conditions in Brazil between 2008 and 2019 were collected through the website of the Departamento de Informática do Sistema Único de Saúde (Information Technology Department of the Unified Health System - DATASUS) maintained by the Brazilian Ministry of Health. Mean annual hospital admissions were 154,009.67, and cumulative incidence of 77.44 admissions per 100,000 inhabitants.Results: Average annual hospital expenses were US$ 67,216,056.04, with an average admission cost of US$ 432.58. The most affected age groups were older adults albeit younger individuals showed a trend towards increase of occurrences in recent years. There were a higher number of admissions in men compared to women.Conclusions: We consider the results obtained important to assist in evaluating and guiding public policies regarding the prevention and treatment in health systems.

The economic burden of schizophrenia in Malaysia.

IntroductionSchizophrenia (SCZ) is a highly debilitating disease despite its low prevalence. The economic burden associated with SCZ is substantial and mainly attributed to productivity loss. To improve the understanding of economic burden of SCZ in the low- and middle-income country regions, we aimed to determine the economic burden of SCZ in Malaysia.MethodsA retrospective study was conducted using a prevalence-based approach from a societal perspective in Malaysia with a 1 year period from 2013. We used micro-costing technique with bottom-up method and included direct medical cost, direct non-medical cost, and indirect cost. The main data source was medical chart review which was conducted in Hospital Kuala Lumpur (HKL). The medical charts were identified electronically by matching the unique patient’s identification number registered under the National Mental Health Schizophrenia Registry and the list of patients in HKL in 2013. Other data sources were government documents, literatures, and local websites. To ensure robustness of result, probabilistic sensitivity analysis was conducted.ResultsThe total estimated number of treated SCZ cases in Malaysia in 2015 was 15,104 with the total economic burden of USD 100 million (M) which was equivalent to 0.04% of the national gross domestic product. On average, the mean cost per patient was USD 6,594. Of the total economic burden of SCZ, 72% was attributed to indirect cost, costing at USD 72M, followed by direct medical cost (26%), costing at USD 26M, and direct non-medical cost (2%), costing at USD 1.7M.ConclusionThis study highlights the magnitude of economic burden of SCZ and informs the policy-makers that there is an inadequate support for SCZ patients. More resources should be allocated to improve the condition of SCZ patients and to reduce the economic burden.

The Economic Burden of Schizophrenia in the United States in 2013

The objective of this study was to estimate the US societal economic burden of schizophrenia and update the 2002 reported costs of $62.7 billion given the disease management and health care structural changes of the last decade. A prevalence-based approach was used to assess direct health care costs, direct non-health care costs, and indirect costs associated with schizophrenia (ICD-9 codes 295.xx) for 2013, with cost adjustments where necessary. Direct health care costs were estimated using a retrospective matched cohort design using the Truven Health Analytics MarketScan Commercial Claims and Encounters, Medicare Supplemental, and Medicaid Multistate databases. Direct non-health care costs were estimated for law enforcement, homeless shelters, and research and training. Indirect costs were estimated for productivity loss from unemployment, reduced work productivity among the employed, premature mortality (ie, suicide), and caregiving. The economic burden of schizophrenia was estimated at $155.7 billion ($134.4 billion-$174.3 billion based on sensitivity analyses) for 2013 and included excess direct health care costs of $37.7 billion (24%), direct non-health care costs of $9.3 billion (6%), and indirect costs of $117.3 billion (76%) compared to individuals without schizophrenia. The largest components were excess costs associated with unemployment (38%), productivity loss due to caregiving (34%), and direct health care costs (24%). Schizophrenia is associated with a significant economic burden where, in addition to direct health care costs, indirect and non-health care costs are strong contributors, suggesting that therapies should aim at improving not only symptom control but also cognition and functional performance, which are associated with substantial non-health care and indirect costs.

Global economic burden of schizophrenia: a systematic review.

BackgroundSchizophrenia is one of the top 25 leading causes of disability worldwide in 2013. Despite its low prevalence, its health, social, and economic burden has been tremendous, not only for patients but also for families, caregivers, and the wider society. The magnitude of disease burden investigated in an economic burden study is an important source to policymakers in decision making. This study aims to systematically identify studies focusing on the economic burden of schizophrenia, describe the methods and data sources used, and summarize the findings of economic burden of schizophrenia.MethodsA systematic review was performed for economic burden studies in schizophrenia using four electronic databases (Medline, EMBASE, PsycINFO, and EconLit) from inception to August 31, 2014.ResultsA total of 56 articles were included in this review. More than 80% of the studies were conducted in high-income countries. Most studies had undertaken a retrospective- and prevalence-based study design. The bottom-up approach was commonly employed to determine cost, while human capital method was used for indirect cost estimation. Database and literature were the most commonly used data sources in cost estimation in high-income countries, while chart review and interview were the main data sources in low and middle-income countries. Annual costs for the schizophrenia population in the country ranged from US$94 million to US$102 billion. Indirect costs contributed to 50%–85% of the total costs associated with schizophrenia. The economic burden of schizophrenia was estimated to range from 0.02% to 1.65% of the gross domestic product.ConclusionThe enormous economic burden in schizophrenia is suggestive of the inadequate provision of health care services to these patients. An informed decision is achievable with the increasing recognition among public and policymakers that schizophrenia is burdensome. This results in better resource allocation and the development of policy-oriented research for this highly disabling yet under-recognized mental health disease.

Conceptualization and treatment of negative symptoms in schizophrenia.

Negative symptoms of schizophrenia including social withdrawal, diminished affective response, lack of interest, poor social drive, and decreased sense of purpose or goal directed activity predict poor functional outcomes for patients with schizophrenia. They may develop and be maintained as a result of structural and functional brain abnormalities, particularly associated with dopamine reward pathways and by environmental and psychosocial factors such as self-defeating cognitions and the relief from overstimulation that accompanies withdrawal from social and role functioning. Negative symptoms are more difficult to treat than the positive symptoms of schizophrenia and represent an unmet therapeutic need for large numbers of patients with schizophrenia. While antipsychotic medications to treat the symptoms of schizophrenia have been around for decades, they have done little to address the significant functional impairments in the disorder that are associated with negative symptoms. Negative symptoms and the resulting loss in productivity are responsible for much of the world-wide personal and economic burden of schizophrenia. Pharmacologic treatments may be somewhat successful in treating secondary causes of negative symptoms, such as antipsychotic side effects and depression. However, in the United States there are no currently approved treatments for severe and persistent negative symptoms (PNS) that are not responsive to treatments for secondary causes. Pharmacotherapy and psychosocial treatments are currently being developed and tested with severe and PNS as their primary targets. Academia, clinicians, the pharmaceutical industry, research funders, payers and regulators will need to work together to pursue novel treatments to address this major public health issue.

Economic burden of schizophrenia: the European situation. A scientific literature review

Background Schizophrenic disorders represent one of the most common public health issues in psychiatry. An estimated 4 million people in Europe suffer from schizophrenia. The European Burden of Disease Report quotes a point prevalence of 0.25-0.56% for schizophrenia. This disorder has been demonstrated to have important social and economic consequences, so it is necessary to assess its economic burden. The aim of this study was to analyze the costs related to …

The economic burden of schizophrenia in Germany: a population-based retrospective cohort study using genetic matching.

Prior studies to determine the economic consequences of schizophrenia have largely been undertaken in clinical settings with a small number of cases and have been unable to analyze effects across different age cohorts. The aim of this study is to investigate the burden of schizophrenia in Germany. Costs, service utilization, and premature mortality attributable to schizophrenia were estimated for the year 2008 using a retrospective matched cohort design. Therefore, 26,977 control subjects as well as 9411 individuals with a confirmed diagnosis of schizophrenia were drawn from a sickness fund claims database. To reduce conditional bias, the non-parametric genetic matching method was employed. The final study population comprised 8224 matched pairs. The annual cost attributable to schizophrenia was €11,304 per patient from the payers' perspective and €20,609from the societal perspective with substantial variations among age groups: direct medical expenses were highest among patients aged>65 years, whereas younger individuals (<25 years) incurred the greatest non-medical costs. The annual burden of schizophrenia from the perspective of German society ranges between €9.63 billionand €13.52 billion. There are considerable differences in the distribution of costs and service utilization for schizophrenia. Because schizophrenia is characterized by an early age of onset and a long duration, research efforts should be targeted at particular populations to obtain the most beneficial outcomes, both clinically and economically.

The personal, societal, and economic burden of schizophrenia in the People's Republic of China: implications for antipsychotic therapy.

BackgroundThis article describes the personal, societal, and economic burden attributable to schizophrenia in the People’s Republic of China and highlights the potential for effective outpatient treatment to reduce this burden given recent changes in the Chinese health care system. The importance of effective antipsychotic therapy in reducing the burden of schizophrenia is also examined.MethodsPublished research on the burden, disability, management, and economic costs of schizophrenia in the People’s Republic of China was examined in the context of the larger body of global research. Research written in English or Chinese and published before June 2012 was identified using PubMed, CNKI, and Wanfang Med database searches. The contribution of effective antipsychotic therapy in reducing the risk for relapse and hospitalization and improving patients’ functioning is described.ResultsSchizophrenia imposes a substantial burden on Chinese society, with indirect costs accounting for the majority of the total cost. Functional impairment is high, leading to lost wages and work impairment. In the People’s Republic of China, schizophrenia is the most common diagnosis among hospitalized psychiatric patients. Ongoing changes in the Chinese health care system may reduce some barriers to effective relapse prevention in schizophrenia and potentially reduce hospitalizations. The use of antipsychotics for acute episodes and maintenance treatment has been shown to decrease symptom severity and reduce the risk for relapse and hospitalization. However, discontinuing antipsychotic medication appears common and is a strong predictor of relapse. Cost-effectiveness research in the People’s Republic of China is needed to examine the potential gains from improved outpatient antipsychotic treatment.ConclusionSchizophrenia is a very costly mental illness in terms of personal, economic, and societal burden, both in the People’s Republic of China and globally. When treated effectively, patients tend to persist longer with antipsychotic treatment, have fewer costly relapses, and have improved functioning. Further research examining the long-term effects of reducing barriers to effective treatments on the societal burden of schizophrenia in the People’s Republic of China is needed.

2995 – Improving schizophrenia outcome

Schizophrenia severely affects mental and physical health. Although 20-50% of patients experience significant improvement at some point in life, schizophrenia is the 5th leading cause of disability in men and the 6th in women; patients with schizophrenia die 12-15 years before the average population, and relatively few of them are in work. It is increasingly acknowledged that much of the personal, social and economic burden of schizophrenia is due to impaired functioning in the real-life of those affected. As a matter of fact, the focus of schizophrenia management has gradually shifted from reduction of symptoms and prevention of relapse to improved functioning in the real-life. The presentation will address the following issues: a) definition and measurement of schizophrenia outcome; b) main variables directly or indirectly influencing functioning in the real-life; c) unmet needs in schizophrenia present management; d) recent treatment strategies and e) priorities for research investments.
