- Objective: Depression cost studies have mainly taken a primary care perspective and should be completed with cost estimates from psychiatric care. The objectives of this study were to estimate the societal per-patient cost of depression in specialized psychiatric care in Sweden, and to relate costs to disease severity, depressive episodes, hospitalization, and patient functioning. Methods: Retrospective resource use data in inpatient and outpatient care for 2006-2008, as well as lCD-10 diagnoses and Global Assessment of Functioning (GAF), were obtained from the Northern Stockholm psychiatric clinic (covering half of Stockholm's population aged 18 years and above). As a complement, data from national registers on pharmaceuticals and sick leave were used in order to estimate the societal cost of depression. Results: Based on 10,430 patients (635, women), the mean annual per patient cost was (sic)17, 279 in 2008. The largest cost item was indirect costs due to productivity losses (88%), followed by outpatient care (6%). Patients with mild and severe depression had average costs of (sic)14,200 and (sic)21,500, respectively. Total costs were substantially higher during depressive episodes, among patients with co-morbid psychosis or anxiety, for hospitalized patients, and for patients with poor functioning. Limitations: Primary care costs and costs for reduced productivity at work were not included. Conclusions: The main cost item among depression patients in psychiatric care was indirect costs. Costs were higher than previously reported for primary care, and strongly related to hospitalization, depressive episodes, and low functioning. This suggests that effective treatment that avoids depressive episodes and hospitalization may reduce society's costs for depression.

The Societal Cost of Schizophrenia in Sweden
- 2013

Journal article (peer-reviewed)abstract
- Background: Schizophrenia is a disabling psychiatric disorder that has severe consequences for patients and their families. Moreover, the expensive treatment of schizophrenia imposes a burden on health care providers and the wider society. Existing cost estimates for Sweden, however, are based on relatively small patient populations and need to be confirmed in a large register-based study. Aims of the Study: To investigate the health care resource utilization and cost-of-illness in patients with schizophrenia in Sweden and to relate the costs to hospitalizations and global assessment of functioning (GAF). Methods: Hospital-based registry data were combined with national registry data from a large patient population to get reliable estimates of the costs of schizophrenia in Sweden. Schizophrenia was defined by ICD-10 codes F20; F21; F23.1,2,8,9; F25.1,8,9. Registry data on socio-demographics and disease-related healthcare resource use in outpatient and inpatient care were obtained from Northern Stockholm Psychiatry. Data on pharmaceuticals were obtained from the National Board of Health and Welfare, and data on sick leave and early retirement were obtained from the Swedish Social Insurance Agency. Costs for community mental health care were not available at the individual level, but were estimated based on previous studies and aggregate cost data from Stockholm. Resource use data from the registries were combined with unit costs from publicly available sources. The study was conducted from a societal perspective, with indirect costs valued according to the human capital method. Results: The average annual psychiatric cost per patient with schizophrenia in 2008 was 42 700 (95% CI: 41 500 44 000), based on a sample of 2 161 patients. To this should be added costs for community mental health care of 12 400 per patient, giving a total cost of 55 100 per patient. The two largest cost items in the total costs were indirect costs due to lost productivity (60%) and community mental health care (22% of the total cost). Patients who were hospitalized in 2008 had greater psychiatric costs than those who were not, (sic)71 700 vs. (sic)37 700 (p<0.0001). Psychiatric costs were significantly and negatively correlated with GAF (p<0.001). Discussion: The major strengths of the study are the relatively large sample, and the linkage of patient-level clinical data on inpatient and outpatient care with national registry data on prescription pharmaceuticals, and days on social insurance. A limitation was that costs for informal care and primary care were not included in the data, but previous studies suggest that these costs items are small compared to other costs for schizophrenia. Implications for Health Policies and Future Research: Costs were strongly related to hospitalization and GAF, suggesting that attempts to improve global functioning and avoid hospitalizations by means of effective treatment and rehabilitation might not only decrease suffering for patients and relatives, but also reduce the societal cost of schizophrenia. A detailed knowledge of the societal costs can also be helpful in evaluating the cost-effectiveness of new treatment strategies to improve the care for patients with schizophrenia.

- Bipolar disorder is a psychiatric disorder characterized by recurrent episodes of mania/hypomania and depression. Progressive cognitive dysfunction such as impairments in executive function and verbal memory is common in euthymic bipolar patients. The cerebrospinal fluid has previously been used to study neurodegenerative processes in Alzheimer’s disease, from which changes in three core biomarkers have emerged as indicative of degeneration: amyloid β, total tau, and hyperphosphorylated tau. Here, neurodegeneration in bipolar disorder was investigated by assessing the association between bipolar disorder and cerebrospinal fluid biomarkers for neurodegenerative processes. Cerebrospinal fluid was obtained from 139 bipolar disorder patients and 71 healthy controls. Concentrations of total and phosphorylated tau, amyloid β1-42, amyloid β38/β40/β42, and the soluble forms of amyloid precursor protein were measured in patients vs controls. The concentrations of the soluble forms of amyloid precursor protein were significantly lower in bipolar patients compared with controls. The amyloid β42/amyloid β38 and the amyloid β42/amyloid β40 ratios were higher in bipolar patients than controls. There were no discernible differences in the concentrations of total/phosphorylated tau, amyloid β1-42, or amyloid β38/β40/β42. The concentrations of the biomarkers within the bipolar patient group were further associated with different ongoing medical treatments and diagnostic subgroups. The findings suggest that the amyloid precursor protein metabolism is altered in bipolar disorder. The results may have implications for the understanding of the pathophysiology of bipolar disorder and for the development of treatment strategies. Importantly, there were no signs of an Alzheimer-like neurodegenerative process among bipolar patients.

Journal article (peer-reviewed)abstract
- Background: Bipolar disorder is a common psychiatric mood disorder that is defined by recurrent episodes of abnormally elevated mood and depression. Progressive structural brain changes in individuals with bipolar disorder have been suggested to be associated with defects in the secretion of neurotrophic factors. We sought to assess how the regulated secretory pathway in the brain is affected in patients with bipolar disorder by measuring chromogranin B and secretogranin II, which are 2 cerebrospinal fluid (CSF) biological markers for this process. Methods: We measured the concentrations of chromogranin B (peptide 439-451) and secretogranin II (peptide 154-165) in the CSF of patients with well-defined bipolar disorder and healthy controls. The lifetime severity of bipolar disorder was rated using the Clinical Global Impression (CGI) scale. Results: We included 126 patients with bipolar disorder and 71 healthy controls in our analysis. Concentrations of secretogranin II were significantly lower in patients with bipolar disorder type I than in healthy controls. The reduction was most pronounced in patients with high CGI scores (i.e., severe disease). Limitations: The cross-sectional design of the current study limits the ability to pinpoint the causalities behind the observed associations. Conclusion: This study shows that the CSF marker secretogranin II has the potential to act as a biological marker for severe forms of bipolar disorder. Our findings indicate that patients with bipolar disorder possess defects in the regulatory secretory pathway, which may be of relevance to the progressive structural brain changes seen in those with severe forms of the disease.

- Irritable mood during mood elevation is common in bipolar disorder. The progesterone metabolite allopregnanolone (ALLO) has been implicated in other disorders presenting with irritability. This study aimed to test whether a history of manic/hypomanic irritability is associated with low serum progesterone levels; and whether single nucleotide polymorphisms (SNPs) in gene coding for steroidogenetic enzymes (HSD3B2, SRD5A1 and AKR1C4 were coupled to previous manic irritability and/or with serum progesterone concentrations.
