Reducing the Risk of Cardiovascular Diseases in Non-selected Outpatients With Schizophrenia: A 30-Month Program Conducted in a Real-life Setting

BACKGROUND

The most common cause of premature death in people with schizophrenia is cardiovascular disease, partially explained by an unhealthy lifestyle, smoking, poor diet and sedentary behavior. We aimed to reduce cardiovascular risk factors.

METHOD

Naturalistic follow-up study with 54 long-term-treated non-selected outpatients with schizophrenia. The 30-month program consisted of individual guidance, group sessions and normal treatment and care offered in our clinic.

RESULTS

On average, the participating women reduced their waist circumference by 11.4cm (P=0.037), whereas the participating men increased their waist circumference by 3.3cm (P=0.590). Patients' consumption of fast food was reduced from 1.2 to 0.8 times/week (P=0.016), just as their consumption of soft drinks was reduced from 0.7 to 0.1l/day (P=0.006). Their consumption of coffee increased from 1.6 to 2.5 cups/day (P=0.086). The time women spent on light physical activity increased from 134 to 469min/week (P=0.055). The number of daily cigarettes smoked was reduced by 25.7% for all smokers.

CONCLUSIONS

Our program showed that it is possible for women but not for men to reduce their risk factors for developing cardiovascular disease. The program is manageable in most outpatient clinics and can be performed by nursing staff interested in physical health with support from and in cooperation with medical doctors, psychiatrist and leaders/managers.

Changes in antipsychotics and other psychotropic drugs during a 30-month lifestyle intervention among outpatients with schizophrenia

BACKGROUND

Patients with schizophrenia have high risk of early death from diabetes and cardiovascular diseases, partly because of poor lifestyle and partly because of long-lasting exposure to antipsychotic treatment.

AIMS

To investigate the influence of a lifestyle intervention program on changes in psychotropic medication in a non-selected cohort of patients with schizophrenia.

METHODS

Observational study of outpatients in the Central Denmark Region during a 30-month lifestyle program.

RESULTS

One hundred and thirty-six patients were enrolled and 130 were available for analysis. Median follow-up time was 15.9 months (range 1-31 months). Nineteen patients (15%) were not treated with antipsychotic drugs during the study period. 54% of the 111 patients exposed to antipsychotics were subject to monotherapy at index and at follow-up. The median defined daily dose (DDD) of antipsychotics was 1.33 at index (interquartile range (IQR) 0.67-2.00) and 1.07 at follow-up (IQR 0.40-1.50). 52% of the patients experienced a decrease in DDD during the study period (median change 0.33; IQR 1.00-0.43). There were no significant differences between the patients with decreased, stable or increased DDD with regard to age, sex, follow-up time and time since diagnosis. The number of prescriptions was significantly higher in the patients who decreased their DDD and the proportion of antipsychotic depot formulation was higher in those who increased their DDD.

CONCLUSIONS

Most patients decreased or stabilized their total dose of antipsychotic medication during the study period. Many patients were subject to antipsychotic polypharmacy. The extent of participation in the lifestyle intervention program did not correlate with the changes in dosing of antipsychotic medication.

Soluble urokinase-type plasminogen activator receptor levels in patients with schizophrenia

BACKGROUND

The etiology of schizophrenia remains largely unknown but alterations in the immune system may be involved. In addition to the psychiatric symptoms, schizophrenia is also associated with up to 20 years reduction in life span. Soluble urokinase-type plasminogen activator receptor (suPAR) is a protein that can be measured in blood samples and reflects the levels of inflammatory activity. It has been associated with mortality and the development of type 2 diabetes and cardiovascular disease.

METHODS

suPAR levels in patients with schizophrenia were compared to healthy controls from the Danish Blood Donor Study. SuPAR levels were dichotomized at >4.0 ng/ml, which is considered the threshold for low grade inflammation. A multiple logistic regression model was used and adjusted for age, sex, and current smoking.

RESULTS

In total we included 1009 subjects, 105 cases with schizophrenia (10.4%) and 904 controls (89.6%). The mean suPAR values were 4.01 ng/ml (SD = 1.43) for the cases vs 1.91 ng/ml (SD = 1.35) for the controls (P < .001). Multiple logistic regression with odds ratio (OR) for suPAR levels >4.0 ng/ml yielded: schizophrenia, OR: 46.15 95% CI 22.69-93.87, P < .001; age, OR: 1.02 95% CI 0.99-1.02, P = .15; male sex, OR: 0.70 95% CI 0.35-1.36, P = .29; and current smoking, OR: 3.51 95% CI 1.78-6.94, P < .001.

CONCLUSIONS

Patients with schizophrenia had significantly higher suPAR levels than healthy controls. Further studies are warranted to clarify if elevated suPAR levels are involved in the pathophysiology of schizophrenia and/or the increased mortality found in patients with schizophrenia.

[Fatigue and loss of appetite as sign of depression in elderly patients]

A 77-year-old woman who, over a period of some months, had changed behavior was subsequently admitted to hospital with loss of weight, fatigue and dizziness. Despite intensive examination, no somatic explanation was found. After a month she was diagnosed with depression but discharged because she refused further treatment. She eventually died. It is important to consider that patients with first episode of major depressive disorder in late life (late-onset geriatric major depression), often present with other prominent symptoms than younger persons.

Patient and relative education in community psychiatry: a randomized controlled trial regarding its effectiveness

BACKGROUND

Family psychoeducation has a well-documented effect on the short-term prognosis in schizophrenia. Less is known about the effectiveness of shorter programmes with the main focus on information for patients (patient education) or for patients and relatives (family education).

METHODS

A randomized study of the effectiveness of an eight-session psychoeducational programme for patients with schizophrenia and for their relatives was conducted in two community mental health centres, in Arhus and Viborg (Denmark). Patient outcome measures were knowledge, relapse, compliance, insight and satisfaction, and relative outcome measures were knowledge and satisfaction. Post-intervention outcome and follow-up evaluation 1 year after the start of the intervention are presented.

RESULTS

A statistically significant increase in knowledge of schizophrenia in both relatives and patients was demonstrated at postintervention and a non-significant trend at 1-year follow-up. Statistically significant changes in the Verona Service Satisfaction Scale Scores in the subdimension of satisfaction with Relatives involvement were demonstrated both for patients and relatives postintervention and for patients at 1-year follow-up. There was a tendency that time-to-relapse increased in the intervention group at postintervention and that the schizophrenia subscore of the Brief Psychiatric Rating Scale was reduced in the intervention group at 1-year follow-up. No differences were found between the groups regarding compliance, insight into psychosis, psychosocial function (General Assessment of Function) or in relatives' expressed emotion scores postintervention or at 1-year follow-up.

CONCLUSIONS

A short patient and relative education programme seems to be able to influence knowledge and some aspects of satisfaction, but does not seem to be sufficient to influence important variables such as relapse, compliance, psychopathology, insight or psychosocial functioning.
