Prepsychosis links with elevated metabolic syndrome
MADRID – Untreated people at high risk for developing psychosis also showed an increased prevalence of certain components of metabolic syndrome in data collected from 163 German study participants, a finding that gives new insight into the well-documented but poorly delineated link between schizophrenia and metabolic syndrome.
“The findings point out that a high risk for schizophrenia implies a certain risk for patients to develop metabolic syndrome independent of treatment effects,” said Dr. Joachim Cordes, a psychiatrist at the LVR Clinic of the Heinrich-Heine University in Düsseldorf, Germany. He assumed that genetic factors underlie the shared risk some people face for both developing schizophrenia and metabolic syndrome. “I think there is a direct connection between schizophrenia and metabolic syndrome, an inherent factor like a genetic factor,” Dr. Cordes said in an interview. This understanding should influence how patients with newly diagnosed schizophrenia or those at risk for psychosis are managed, he added.
Dr. Cordes’s report was one of several at the meeting sponsored by the European Psychiatric Association that examined different facets of the complex links that tie schizophrenia to metabolic syndrome, an association that already had lots of evidence, including a recent meta-analysis (Schizophr Bull. 2013 March;39[2]:306-18).
He used data collected on 163 people enrolled in the PREVENT study and at high risk for a first psychotic episode. Run at nine German centers, PREVENT primarily tested very early intervention with drug and behavioral therapy to improve outcomes. Dr. Cordes took data collected from these prepsychosis, high-risk patients to assess their prevalence of metabolic syndrome and of the various individual features that define metabolic syndrome, using a definition published by the American Heart Association and the U.S. National Heart, Lung, and Blood Institute (Circulation. 2005 Oct 18;112[17]:2735-52). He compared these metabolic syndrome rates with the general German population, using data from 35,869 randomly selected German adults in more than 1,500 German primary care practices, the German Metabolic and Cardiovascular Risk Project (GEMCAS).
The findings showed a 9.2% prevalence of metabolic syndrome in the prepsychosis group and a 7.4% rate among the general adult population, Dr. Cordes reported. Among men in the prepsychosis group, the metabolic syndrome definers with the largest increments in prevalence were low HDL, in 21% of the prepsychosis people and in 12% of the general population, and elevated blood glucose in 11%, compared with 6%. Among women, the metabolic syndrome definers with the greatest between-group differences were elevated waist circumference, in 30% of those with prepsychosis, compared with 17% in the general population, and low HDL in 19%, compared with 14%.
This apparently inherent link between a tendency toward psychosis and schizophrenia and a tendency to develop features of metabolic syndrome suggests that patients with newly diagnosed schizophrenia need a preventive approach to weight management, Dr. Cordes said. He also suggested prescribing antipsychotic medications that pose the lowest risk for causing further metabolic derangements in patients.
A second report at the meeting came from an assessment of cognitive function and its relationship to metabolic syndrome in 54 women diagnosed with schizophrenia and on stable treatment. The schizophrenia patients with metabolic syndrome, nearly half of the total group, performed significantly worse than those without metabolic syndrome in tests of verbal memory, executive function, and attention and processing speed, findings that support an increased incidence of selective cognitive impairment in patients with schizophrenia and metabolic syndrome, said Dr. Adela C. Botis, a psychiatrist and researcher at the University of Medicine and Pharmacy in Cluj-Napoca, Romania.
Dr. Botis and her associates studied 54 women diagnosed with schizophrenia who had remitted symptoms for at least 6 months on stable antipsychotic treatment. Using the metabolic syndrome definition of the International Diabetes Federation 25 (46%) had metabolic syndrome, and the other 29 (54%) did not. These numbers document the high prevalence of metabolic syndrome in schizophrenia patients.
A multivariate analysis identified demographic and metabolic factors that significantly linked with decrements in several cognitive domains. Economic status and living situation linked with deficits in verbal memory; elevated systolic blood pressure significantly linked with worsened attention and processing speed; high body mass index linked with loss of motor speed; and less education significantly linked with all these increments as well as four other domains,
A third report used a post-hoc analysis of data from two separate trials to show that treatment with a relatively new antipsychotic drug, lurasidone (Latuda), produced less metabolic syndrome, compared with risperidone or extended-release quetiapine (Seroquel XR), said Dr. Andrei Pikalov, head of global medical affairs at Sunovion Pharmaceuticals, the company that markets Latuda. Lurasidone received approval for treating schizophrenia in 2010.
He took data from two studies designed to assess lurasidone’s efficacy for treating adults with schizophrenia for 12 months, compared with either risperidone in a study with 621 patients, or with quetiapine XR in a study with 292 patients. He applied the same metabolic syndrome definition used by Dr. Cordes to clinical measurements taken at baseline and after 12 months on treatment.
The results showed that treatment with lurasidone produced less than half the rate of new metabolic syndrome cases, compared with risperidone, a statistically significant difference, and less than two-thirds the rate of quetiapine XR, a difference that did not reach statistical significance.
Dr. Cordes said he has been a speaker for Servier. Dr. Botis had no disclosures. Dr. Pikalov is an employee of Sunovion, which markets lurasidone (Latuda).

Antidepressants Tied to Lower Dementia Mortality
MADRID – Elderly patients who develop dementia often are on an antidepressant when dementia is diagnosed, and unexpectedly antidepressant use during the 3 years preceding diagnosis of dementia was linked with a significantly reduced mortality risk, Dr. Daniela Enache reported at the meeting, sponsored by the European Psychiatric Association.
Elderly Swedish patients who took an antidepressant for at least 1 year during the 3 years prior to their dementia diagnosis had a 13% relative reduction in mortality, compared with similar new-dementia patients who had not been on an antidepressant. The researchers tracked mortality for a median of 2.1 years following dementia diagnosis in 20,050 Swedes with a new dementia diagnosis using records from 2007-2013, said Dr. Enache, a psychiatrist and neurogeriatics researcher at the Karolinska Institute in Stockholm. The analysis adjusted for differences in age, sex, mental state, number of drugs used, and living conditions.
The protective effect from 3 years of antidepressant use was strongest in people who went on to develop Alzheimer’s disease, the most common form of dementia in the study affecting 36% of all people who developed dementia. The findings also documented the relatively frequent antidepressant use by elderly people who develop dementia. In the series of people with newly diagnosed dementia of any type, 25% were on an antidepressant at the time of their dementia diagnosis, and 4,325 (22%) had used an antidepressant at least once during the 3 years prior to their diagnosis; 1,128 (6%) of the people diagnosed with dementia had used an antidepressant during all 3 years preceding their diagnosis.
Dr. Enache admitted that it was not clear why antidepressant treatment would have this mortality effect. One possibility is that the mortality benefit came from the action of antidepressants on behavioral symptoms. Or antidepressants could have a biological effect, such as reducing production of amyloid beta or affecting neurogenesis and brain plasticity. A third possibility is that antidepressant use is a marker for overall better health care.
Whatever the explanation, the finding provides reassurance that antidepressant treatment is safe in elderly patients who are at risk of developing dementia, she noted. And patients newly diagnosed with dementia should be screened for depression, although Dr. Enache stressed that antidepressants can be prescribed for other reasons, such as anxiety or behavior problems.
All types of antidepressants had this mortality effect: tricyclics, selective serotonin reuptake inhibitors, and other types. Use of antidepressants was roughly similar across various dementia diagnoses, ranging from 22% of patients with mixed dementia and 23% of those with Alzheimer’s disease to a high of 32% among patients with Parkinson’s disease dementia.
The researchers used data collected in the national Swedish Dementia Registry, which includes about 90% of patients treated at Swedish memory clinics, along with data from the national Prescribed Drug Registry. The average age at time of dementia diagnosis was 78 years. Following Alzheimer’s disease, the other most common diagnoses were mixed dementia, in 25%, and vascular dementia, in 19%.
Dr. Enache had no disclosures.
These were quite surprising findings: a mortality reduction linked with antidepressant treatment, Dr. Reinhard Heun said in an interview. We’ll see if someone can replicate this. Perhaps the finding was caused by an unadjusted selection bias, or an effect from a comorbidity. Or it could be that patients on antidepressants also received better health care. Seeing a mortality benefit is difficult to explain.
Mitchel L. Zoler/Frontline Medical News Dr. Reinhard Heun |
Hypothesizing an actual causal link between antidepressant use and reduced mortality in patients recently diagnosed with dementia would mean that antidepressants have an effect on underlying dementia pathology. That seems unlikely. Treatment of depression in elderly patients is primarily focused on improving patients’ quality of life, and there is good evidence that antidepressant treatment achieves that. Improving quality of life is a much more realistic goal for antidepressant therapy than improving survival.

Elderly Swedish patients who took an antidepressant for at least 1 year during the 3 years prior to their dementia diagnosis had a 13% relative reduction in mortality, compared with similar new-dementia patients who had not been on an antidepressant. The researchers tracked mortality for a median of 2.1 years following dementia diagnosis in 20,050 Swedes with a new dementia diagnosis using records from 2007-2013, said Dr. Enache, a psychiatrist and neurogeriatics researcher at the Karolinska Institute in Stockholm. The analysis adjusted for differences in age, sex, mental state, number of drugs used, and living conditions.
The protective effect from 3 years of antidepressant use was strongest in people who went on to develop Alzheimer’s disease, the most common form of dementia in the study affecting 36% of all people who developed dementia. The findings also documented the relatively frequent antidepressant use by elderly people who develop dementia. In the series of people with newly diagnosed dementia of any type, 25% were on an antidepressant at the time of their dementia diagnosis, and 4,325 (22%) had used an antidepressant at least once during the 3 years prior to their diagnosis; 1,128 (6%) of the people diagnosed with dementia had used an antidepressant during all 3 years preceding their diagnosis.
Dr. Enache admitted that it was not clear why antidepressant treatment would have this mortality effect. One possibility is that the mortality benefit came from the action of antidepressants on behavioral symptoms. Or antidepressants could have a biological effect, such as reducing production of amyloid beta or affecting neurogenesis and brain plasticity. A third possibility is that antidepressant use is a marker for overall better health care.
Whatever the explanation, the finding provides reassurance that antidepressant treatment is safe in elderly patients who are at risk of developing dementia, she noted. And patients newly diagnosed with dementia should be screened for depression, although Dr. Enache stressed that antidepressants can be prescribed for other reasons, such as anxiety or behavior problems.
All types of antidepressants had this mortality effect: tricyclics, selective serotonin reuptake inhibitors, and other types. Use of antidepressants was roughly similar across various dementia diagnoses, ranging from 22% of patients with mixed dementia and 23% of those with Alzheimer’s disease to a high of 32% among patients with Parkinson’s disease dementia.
The researchers used data collected in the national Swedish Dementia Registry, which includes about 90% of patients treated at Swedish memory clinics, along with data from the national Prescribed Drug Registry. The average age at time of dementia diagnosis was 78 years. Following Alzheimer’s disease, the other most common diagnoses were mixed dementia, in 25%, and vascular dementia, in 19%.

Lifestyle Intervention Blocks Antipsychotic-associated Weight Gain
MADRID – The weight gain most patients have when first starting treatment with antipsychotic medications is not inevitable.
A 12-week intervention program designed to promote exercise and a healthy diet largely blunted a big weight gain by 16 adolescents and young adults starting treatment after an initial diagnosis of psychosis in a controlled study at a single Australian center. Later follow-up further showed that a majority of participants in the program remained mostly free of excess weight 2 years after the life-style intervention, Dr. Philip B. Ward said at the meeting sponsored by the European Psychiatric Association.
Implementing this type of intervention is very important because antipsychotic-induced weight gain launches young psychiatric patients into a middle age that often includes metabolic syndrome, type 2 diabetes, and a significantly increased risk for cardiovascular disease events, said Dr. Ward, a psychiatrist at the University of New South Wales in Sydney.
He reported results from a pilot program, Keeping the Body in Mind, run at one of the university’s community clinics that gave newly-diagnosed psychiatric patients aged 15-25 years regular instruction in diet, food shopping, and cooking and in an exercise class that included individualized coaching over the course of 12 weeks. At the end of the program, average weight gain relative to baseline weight was 1.8 kg among 16 patients in the intervention group and 7.8 kg among 12 patients who received standard care at a different community clinic. (Early Interv Psychiatry. 2015. doi: 10.1111/eip.12230).
Expressed another way, 2 of the 16 participating patients (13%) had a clinically significant (at least 7%) weight gain during the 12-week program, compared with 9 of the 12 (75%) of patients with a significant weight gain in the control group.
To assess the durability of this effect, Dr. Ward and his associates did follow-up 2 years later on 12 of the participants, who showed an average 1.3-kg weight gain after 2 years, compared with their weight at the time they entered the program, Dr Ward reported. Based on this success, the university’s psychiatric clinics are now expanding the program to make it available to all patients starting treatment on antipsychotic medications, about 80 patients a year, Dr. Ward said in an interview.
Although Dr. Ward stressed the importance of lifestyle intervention, he noted that the antipsychotic drug selected for treatment can also affect the magnitude of acute weight gain. Two drugs that seem to pose some of the lowest weight-gain risks are aripiprazole and ziprasidone.

Brexpiprazole combined analysis shows schizophrenia safety, efficacy
MADRID – Brexpiprazole, a new drug for treatment of schizophrenia that received Food and Drug Administration marketing approval in July 2015, showed good efficacy for patients with acute schizophrenia as well as a good safety profile in a combined analysis from three phase III trials that compared the drug against placebo.
“The incidence of withdrawals due to adverse effects was lower with brexpiprazole administered as 2-4 mg/day than with placebo, and the incidence of activating and sedating effects with brexpiprazole was low, Catherine Weiss, Ph.D., reported at the meeting, sponsored by the European Psychiatric Association.
“For long-term treatment, the lower level of sedation from treatment with brexpiprazole is an advantage,” said Dr. Weiss, director of global medical affairs for Otsuka, the company that is marketing brexpiprazole (Rexulti) along with a partner company, Lundbeck.
“We hope that brexpiprazole will be suitable for outpatients with schizophrenia who still have the potential to function in the community, to work and have relationships. Our data show that brexpiprazole prevents schizophrenia relapses and is very well tolerated,” said Dr. Emmanuelle Weiller, a senior medical adviser with Lundbeck in Copenhagen.
In its announcement of the marketing approval for brexpiprazole last year, the FDA did not include any description of how the drug works. But according to a statement from Lundbeck, the efficacy of brexpiprazole may be mediated by partial or full agonist activity at certain serotonin or dopamine receptors. The drug also has high affinity for certain noradrenaline alpha receptors.
The FDA based its approval for treatment of adults with schizophrenia (the drug was simultaneously also approved for adjunctive treatment of adults with major depressive disorder) on the results from two pivotal trials that both were published last year (Am Psychiatry. 2015 Sept 1;172[9]:870-80 and Schizophr Res. 2015 May;164[1-3]:127-35).
Dr. Weiss’ combined analysis used data collected in both of these trials as well as in a third trial, the results of which were reported in a separate talk during the same meeting session. The third brexpiprazole trial randomized 468 adults with schizophrenia to one of three treatment groups: patients who received a flexible brexpiprazole dosage, patients who received placebo, and patients randomized to treatment with quetiapine XR, a subgroup that served as an active reference arm but not a comparator arm.
The combined analysis focused on the 868 patients in any of the three trials who received either 2 mg or 4 mg of brexpiprazole daily and its comparison to 517 patients who received placebo during 6 weeks of treatment. The combined results showed an overall, average incremental reduction in the positive and negative syndrome scale (PANSS) score of 5.8 with brexpiprazole treatment compared with placebo, a statistically significant difference, Dr. Weiss reported. Treatment with brexpiprazole for 6 weeks also produced significant improvements compared with placebo for three secondary efficacy measures: clinical global impression of severity, clinical global impression of improvement, and personal and social performance.
The safety analysis showed that treatment-emergent adverse events leading to withdrawal from treatment occurred in 8% of patients on brexpiprazole and in 13% of those on placebo. None of the most common treatment-emergent adverse effects were substantially more common in the brexpiprazole-treated patients, compared with those on placebo.
Brexpiprazole’s likely role right now is as an alternative maintenance drug for patients whose schizophrenia is either not adequately controlled by an older agent, or for patients who experience intolerable adverse effects on an older drug and would like an alternative drug that does not interfere as much with their usual activities, Dr. Weiller said in an interview.
