- Background: Given that adults with ADHD continue to use stimulants for extended periods of time, studies on the long-term effectiveness and adverse events are warranted. The aims of this study were to investigate factors associated with persistence in treatment in an exploratory manner and to document side effects and reasons for discontinuation.Method: The current study describes the systematic follow-up of 133 psychiatric patients with DSM-IV-diagnosed ADHD treated with central stimulants at a specialized outpatient unit between January 1, 2001, and August 31, 2006. A standardized questionnaire, derived from the Targeted Attention-deficit Disorder Symptoms Rating Scale, was used in order to measure improvement of the following target symptoms: hyperactivity, impulsivity, irritability, distractibility, structure/organization problems, inattention, and restlessness.Results: Eighty percent of the patients were successfully treated with stimulants at the 6- to 9-month follow-up. Fifty percent remained in treatment after 2 years or more. Forty-five percent were treated for comorbid anxiety and/or depression during the study period. Only 15% dropped out because of lack of efficacy. The amount of clinical response over the first 6 to 9 months (but not at 6 weeks) predicted adherence to treatment at 2 years. The patients' heart rate increased from a least squares mean ± SE of 70 ± 2.2 to 80 ± 2.1 bpm (P = .00003) while blood pressure remained unchanged at the ≥ 2-year follow-up. Severe side effects or drug abuse were not detected in this cohort.Conclusions: The long-term treatment outcome shows that stimulants are effective in adult ADHD and side effects tend to be mild.

Prediction of Alzheimer's disease using midregional proadrenomedullin and midregional proatrial natriuretic peptide: a retrospective analysis of 134 patients with mild cognitive impairment.
- 2011

In: The Journal of clinical psychiatry. - 1555-2101 .- 0160-6689. ; 72:4, s. 556-63

Journal article (peer-reviewed)abstract
- OBJECTIVE: Development of biomarkers for early detection of Alzheimer's disease (AD) is a major clinical research goal. On the basis of the hypothesis that cardiovascular risk factors contribute to the pathogenesis of AD, we investigated whether the cardiovascular risk markers midregional proadrenomedullin (MR-proADM) and midregional proatrial natriuretic peptide (MR-proANP) predict a major clinical milestone, ie, conversion from predementia mild cognitive impairment (MCI) to manifest AD. METHOD: A group of 134 MCI patients, among 137 originally prospectively recruited at the memory disorder clinic at Malmö University Hospital, Malmö, Sweden, between July 1998 and June 2001, was clinically followed for 4-6 years. We determined whether plasma concentrations of MR-proADM and MR-proANP at baseline predicted time to conversion from MCI to clinically diagnosed AD (DSM-III-R). MCI was diagnosed according to Petersen criteria. RESULTS: During follow-up, 41.8% of MCI patients remained cognitively stable, 42.5% converted to possible and probable AD, and 15.7% converted to other forms of dementia (MCI-other). MCI converters and MCI-other patients showed increased concentrations of MR-proANP and MR-proADM compared to the stable MCI patients (P = .0001). At a cutoff of 87 pmol/L, MR-proANP yielded a sensitivity of 73.7% and a specificity of 64.3% for predicting conversion to AD. The survival analysis showed that higher values of MR-proANP and MR-proADM were associated with progression to AD. In a multivariate Cox regression model including known risk factors, MR-proANP and MR-proADM remained independent risk factors for conversion to AD for patients below the age of 72 years. CONCLUSIONS: Our study shows that plasma concentrations of MR-proANP and MR-proADM have predictive value in the progression from predementia MCI to clinical AD. Sensitivity was particularly high, which may recommend this test for first-stage screening in patients at risk for AD.

Informant agreement in the assessment of disruptive behavior disorders in detained minors in Belgium : a diagnosis-level and symptom-level examination
- 2008
-
In: Journal of Clinical Psychiatry. - : Physicians Postgraduate Press, Inc. - 0160-6689 .- 1555-2101. ; 69:1, s. 141-148
-
Journal article (peer-reviewed)abstract
- OBJECTIVE: Because diagnostic assessment of children emphasizes information from multiple informants, the reliability of findings in detained and incarcerated samples may be hampered. The objective of the current study was to examine parent-child agreement with regard to disruptive behavior disorders (with or without impairment) and disorder-related symptoms in detained male youths.METHOD: Between January 2005 and February 2007, a representative sample of 150 detainees, 12 to 17 years old, from the 3 Youth Detention Centers for boys in Flanders, Belgium, and 1 parent of each were interviewed with the Diagnostic Interview Schedule for Children, Version IV (DISC-IV). Interviewees were selected consecutively on the basis of Belgian origin for practical, financial, and time-related reasons. Of the 150 participants, 9 were excluded and the parents of 26 could not be included for various reasons, and thus full data were obtained for 115 parents.RESULTS: Overall poor parent-child agreement at the disorder and symptom level was found, which is consistent with previous studies. Parents reported significantly more unique information on attention-deficit/hyperactivity disorder (ADHD) (p < .001) and oppositional defiant disorder (ODD) (p < .001), while youths reported significantly more unique conduct disorder (CD)-related information (p = .01).CONCLUSION: The large proportion of parents uniquely reporting ADHD and ODD supports previous concerns about the reliability of self-reported ADHD and ODD and suggests an essential contribution by parents to the accurate assessment of these disorders in adolescent detainees. With regard to CD, it may be appropriate to rely on youth self-report.

Adding Psychotherapy to Pharmacotherapy in the Treatment of Depressive Disorders in Adults : A Meta-Analysis
- 2009
-
In: JOURNAL OF CLINICAL PSYCHIATRY. - 0160-6689 .- 1555-2101. ; 70:9, s. 1219-1229
-
Journal article (peer-reviewed)abstract
- Objective: A considerable number of studies has examined whether adding psychotherapy to pharmacotherapy results in stronger effects than pharmacotherapy alone. However, earlier meta-analyses in this field have included only a limited number of available studies and did not conduct extended subgroup analyses to examine possible sources of heterogeneity. Data Sources: We used a database derived from a comprehensive literature search in Pubmed, PsycINFO, EMBASE, and the Cochrane Central Register of Controlled Trials for studies published from 1966 to January 2008 that examined the psychological treatment of depression. The abstracts of these studies were identified by combining terms indicative of psychological treatment and depression. Study Selection: We included randomized trials in which the effects of a pharmacologic treatment were compared to the effects of a combined pharmacologic and psychological treatment in adults with a depressive disorder. Data Extraction: For each of the studies, we calculated a standardized mean effect size indicating the difference between pharmacotherapy and the combined treatment at posttest. We also coded major characteristics of the population, the interventions, and the quality and design of the study. Data Synthesis: Twenty-five randomized trials, with a total of 2,036 patients, were included. A mean effect size of d=0.31 (95% CI, 0.20 similar to 0.43) was found for the 25 included studies, indicating a small effect in favor of the combined treatment over pharmacotherapy alone. Studies aimed at patients with dysthymia resulted in significantly lower effect sizes compared to studies aimed at patients with major depression, a finding that suggests that the added value of psychotherapy is less in patients with dysthymia. The dropout rate was significantly lower in the combined treatment group compared to the pharmacotherapy only group (OR = 0.65; 95% CI, 0.50 similar to 0.83). Conclusions: Psychotherapy seems to have an additional value compared to pharmacotherapy alone for depression.

Are Psychological and Pharmacologic Interventions Equally Effective in the Treatment of Adult Depressive Disorders? : A Meta-Analysis of Comparative Studies
- 2008
-
In: Journal of Clinical Psychiatry. - 0160-6689 .- 1555-2101. ; 69:11, s. 1675-1685
-
Journal article (peer-reviewed)abstract
- Objective: A large number of studies suggest that both psychological and pharmacologic therapies are effective in the treatment of mild-to-moderate depressive disorders. Whether both types of intervention are equally effective has not been established definitively. Data Sources: A database was developed through a comprehensive literature search (from 1966 to May 2007) in which 6947 abstracts in PubMed (1244 abstracts), PsycINFO (1736), EMBASE (1911), and the Cochrane Central Register of Controlled Trials (2056) were examined. Abstracts were identified by combining terms indicative of psychological treatment and depression (both MeSH terms and text words). For this database, the primary studies from 22 meta-analyses of psychological treatment for depression were also collected. Study Selection: For the current study, the abstracts of 832 studies were examined. Data Extraction: Thirty randomized trials were included in a meta-analysis that compared the effects of a psychological treatment for 3178 adults with a diagnosed depressive disorder (major depressive disorder, dysthymia, minor depressive disorder) with the effects of a pharmacologic treatment. Data Synthesis: In studies of patients with dysthymia, pharmacotherapy was significantly more effective than psychotherapy (d = -0.28, 95% CI = -0.47 to -0.10). In patients with major depressive disorder, treatments with selective serotonin reuptake inhibitors (SSRIs) were significantly more effective than psychological treatments, while treatment with other antidepressants did not differ significantly. Subgroup and metaregression analyses did not show that pretest severity of depressive symptoms was associated with differential effects of psychological and pharmacologic treatments of major depressive disorder. Dropout rates were smaller in psychological interventions compared with pharmacologic treatments (odds ratio = 0.66, 95% CI = 0.47 to 0.92). Conclusions: Pharmacologic treatments may be more effective than psychological interventions in the treatment of dysthymia. Pharmacologic treatment with SSRIs may also be more effective in the treatment of major depressive disorder, although these differences are small and probably have little meaning from a clinical point of view. We can conclude that both psychological and pharmacologic therapies are effective in the treatment of depressive disorders and that each has its own merits.

Can psychotherapists function as their own controls? Meta-analysis of the crossed therapist design in comparative psychotherapy trials
- 2013
-
In: Journal of Clinical Psychiatry. - : Physicians Postgraduate Press. - 0160-6689 .- 1555-2101. ; 74:5, s. 482-491
-
Journal article (peer-reviewed)abstract
- OBJECTIVE:Clinical trials sometimes have the same therapists deliver more than 1 psychotherapy, ostensibly to control for therapist effects. This "crossed therapist" design makes controlling for therapist allegiance imperative, as therapists may prefer one treatment they deliver to the other(s). Research has established a strong relationship between principal investigators' allegiances and treatment outcome. Study therapists' allegiances probably also influence outcome, yet this moderating factor on outcome has never been studied.DATA SOURCES:English language abstracts in PsycINFO and MEDLINE from January 1985 to December 2011 were searched for keywords psychotherapy and randomized trial.STUDY SELECTION:The search yielded 990 abstracts that were searched manually. Trials using the same therapists in more than 1 condition were included.DATA EXTRACTION:Thirty-nine studies fulfilled inclusion criteria. Meta-regression analyses assessed the influence of researchers' allegiance on treatment outcome, testing the hypothesis that studies poorly controlling for therapist allegiance would show stronger influence of researcher allegiance on outcome. A single-item measure assessed researchers' reported attempts to control for therapist allegiance.RESULTS:Only 1 of 39 studies (3%) measured therapist treatment allegiance. Another 5 (13%) mentioned controlling for, without formally assessing, therapist allegiance. Most publications (67%) did not even mention therapist allegiance. In studies not controlling for therapist allegiance, researcher allegiance strongly influenced outcome, whereas studies reporting control for therapist allegiance showed no differential researcher allegiance. Researchers with cognitive-behavioral therapy allegiance described controlling for therapist allegiance less frequently than other researchers.CONCLUSIONS:The crossed therapist design is subject to bias due to differential psychotherapist allegiance. Worrisome results suggest that researchers strongly allied to a treatment may ignore therapist allegiance, potentially skewing outcomes. All clinical trials, and especially crossed therapist designs, should measure psychotherapist allegiance to evaluate this possible bias.

Risk Factors for Violent Crime in Schizophrenia : A National Cohort Study of 13,806 Patients
- 2009
-
In: Journal of Clinical Psychiatry. - 0160-6689 .- 1555-2101. ; 70:3, s. 362-369
-
Journal article (peer-reviewed)abstract
- Objective: To determine risk factors for and prevalence of violent crime in patients with schizophrenia, and in particular, to explore the contribution of familial risk factors. Method: We designed a cohort study that followed up patients with 2 or more hospitalizations for schizophrenia (ICD-8, ICD-9, and ICD-10 criteria) and investigated the risk for a violent conviction using Cox proportional hazards models. All 13,806 patients with 2 hospital discharge diagnoses of schizophrenia from January 1, 1973. through December 31, 2004, in Sweden were followed until violent conviction, emigration, death, or end of follow-up (December 31, 2004), and associations with sociodemographic, individual (substance abuse comorbidity, and previous violence), and familial (parental violent crime and parental alcohol abuse) factors were examined. Results: Over an average follow-up period of 12 years, 17.1% (N = 15 19) of the men and 5.6% (N = 273) of the women with 2 or more hospitalizations for schizophrenia had a violent conviction after discharge from hospital. Familial risk factors had moderate effects, increasing the risk for violent convictions by 50% to 150%. After adjustment for sociodemographic and individual risk factors, the associations between parental violent crime and risk of violent convictions remained in men (adjusted hazard ratio [HR] = 1.65, 95% Cl = 1.33 to 2.04) and in women (adjusted HR = 1.83. 95% CI = 1.11 to 3.01), whereas parental alcohol abuse was no longer significantly associated with violent crime. Conclusion: Parental violent crime had moderate associations with violent crime in male and female offspring with at least 2 hospitalizations for schizophrenia, which were mostly stronger than the better documented sociodemographic risk factors. This suggests that familial (genetic or early environmental) risk factors have an important role in the etiology of violent offending among individuals with schizophrenia and should be considered in violence risk assessment.

Suicide after release from prison : a population-based cohort study from Sweden
- 2014
-
In: Journal of Clinical Psychiatry. - : Physicians Postgraduate Press, Inc. - 0160-6689 .- 1555-2101. ; 75:10, s. 1047-53
-
Journal article (peer-reviewed)abstract
- OBJECTIVE: Released prisoners have high suicide rates compared with the general population, but little is known about risk factors and possible causal pathways. We conducted a population-based cohort study to investigate rates and risk factors for suicide in people previously imprisoned.METHOD: We identified individuals released from prison in Sweden between January 1, 2005, and December 31, 2009, through linkage of national population-based registers. Released prisoners were followed from the day of release until death, emigration, new incarceration, or December 31, 2009. Survival analyses were conducted to compare incidence rates and psychiatric morbidity with nonconvicted population controls matched on gender and year of birth.RESULTS: We identified 38,995 releases among 26,985 prisoners (7.6% female) during 2005-2009. Overall, 127 suicides occurred, accounting for 14% of all deaths after release (n = 920). The mean suicide rate was 204 per 100,000 person-years, yielding an incidence rate ratio of 18.2 (95% CI, 13.9-23.8) compared with general population controls. Previous substance use disorder (hazard ratio [HR] = 2.1; 95% CI, 1.4-3.2), suicide attempt (HR = 2.5; 95% CI, 1.7-3.7), and being born in Sweden versus abroad (HR = 2.1; 95% CI, 1.2-3.6) were independent risk factors for suicide after release.CONCLUSIONS: Released prisoners are at high suicide risk and have a slightly different pattern of psychiatric risk factors for suicide compared with the general population. Results suggest appropriate allocation of resources to facilitate transition to life outside prison and increased attention to prisoners with both a previous suicide attempt and substance use disorder.

Suicide Immediately After Discharge From Psychiatric Inpatient Care : A Cohort Study of Nearly 2.9 Million Discharges
- 2019
-
In: Journal of Clinical Psychiatry. - : Physicians Postgraduate Press. - 0160-6689 .- 1555-2101. ; 80:2
-
Journal article (peer-reviewed)abstract
- OBJECTIVE: The risk of suicide is elevated after discharge from a psychiatric hospital. This study aimed to investigate how recent suicidal behavior affects the risk of suicide in patients with different psychiatric diagnoses immediately after discharge.METHODS: Registers with national coverage were linked to create a study cohort including all individuals discharged from psychiatric hospitals in Sweden from 1973 through 2009. Hazard ratios for discharge diagnoses were calculated. The risk of suicide within 30 days after discharge in each diagnostic category when suicidal behavior had been registered within 30 days before admission was estimated.RESULTS: A total of 3,695 suicides occurred after 2,883,088 discharges. If recent suicidal behavior was registered, the risk of completed suicide increased prominently in all diagnostic categories, but particularly for schizophrenia (hazard ratio [HR] = 8.9; 95% CI, 6.4-12.4) and other nonorganic psychosis (HR = 6.8; 95% CI, 5.1-9.0). Patients suffering from depression had the highest overall risk of suicide postdischarge (HR = 3.0; 95% CI, 2.7-3.3). This finding applied especially to male patients with depression (HR = 4.5; 95% CI, 4.0-5.0) or with reaction to crisis (HR = 3.6; 95% CI 3.0-4.4).CONCLUSIONS: A distinct elevation of the risk of suicide was seen in all diagnostic groups if a recent self-harm event had occurred, particularly among patients with psychotic disorders. Overall, the immediate risk of suicide after discharge was high regardless of recent suicidal behavior. The findings in this study have relevance for clinical decisions about immediate after-care and treatment in connection with discharge from psychiatric inpatient care.

Lithium trial in Alzheimer's disease : a randomized, single-blind, placebo-controlled, multicenter 10-week study
- 2009
-
In: Journal of Clinical Psychiatry. - 0160-6689 .- 1555-2101. ; 70:6, s. 922-931
-
Journal article (peer-reviewed)abstract
- OBJECTIVE: Lithium, a first-line drug for the treatment of bipolar depression, has recently been shown to regulate glycogen synthase kinase-3 (GSK-3), a kinase that is involved in the phosphorylation of the tau protein. Since hyperphosphorylation of tau is a core pathological feature in Alzheimer's disease, lithium-induced inhibition of GSK-3 activity may have therapeutic effects in Alzheimer's disease. In the current study, we tested the effect of short-term lithium treatment in patients with Alzheimer's disease. METHOD: A total of 71 patients with mild Alzheimer's disease (Mini-Mental State Examination score > or = 21 and < or = 26) were successfully randomly assigned to placebo (N = 38) or lithium treatment (N = 33) at 6 academic expert memory clinics. The 10-week treatment included a 6-week titration phase to reach the target serum level of lithium (0.5-0.8 mmol/L). The primary outcome measures were cerebrospinal fluid (CSF) levels of phosphorylated tau (p-tau) and GSK-3 activity in lymphocytes. Secondary outcome measures were CSF concentration of total tau and beta-amyloid(1-42) (Abeta(1-42)), plasma levels of Abeta(1-42), Alzheimer's Disease Assessment Scale (ADAS)-Cognitive summary scores, MMSE, and Neuropsychiatric Inventory (NPI). Patients were enrolled in the study from November 2004 to July 2005. RESULTS: No treatment effect on GSK-3 activity or CSF-based biomarker concentrations (P > .05) was observed. Lithium treatment did not lead to change in global cognitive performance as measured by the ADAS-Cog subscale (P = .11) or in depressive symptoms. CONCLUSIONS: The current results do not support the notion that lithium treatment may lead to reduced hyperphosphorylation of tau protein after a short 10-week treatment in the Alzheimer's disease target population.

CYP2D6 Genotyping and Inhibition as Predictors of Adverse Drug Reactions in Depressive Disorders
- 2024
-
In: Journal of Clinical Psychiatry. - : PHYSICIANS POSTGRADUATE PRESS. - 0160-6689 .- 1555-2101. ; 85:1
-
Journal article (peer-reviewed)abstract
- Objective: The primary aim of this study was to examine the association between the different predicted phenotypes of the polymorphic CYP2D6 gene and the prevalence of adverse drug reactions in patients suffering from depressive disorders. The secondary aim was to investigate if comedication with CYP2D6 inhibitors resulted in more adverse drug reactions due to phenoconversion. Methods: Between January 2012 and December 2021, 415 patients with a depressive disorder and insufficient treatment response in secondary psychiatric care were included in the naturalistic observational study Genes, Depression, and Suicidality (GENDS). The patients were subjected to a semistructured interview and diagnosed according to DSM-IV . Patients were also required to complete the self-rating version of the UKU Side Effect Rating Scale. All patients were genotyped for CYP2D6 and assigned a corresponding predicted CYP2D6 phenotype. Results: Out of the 415 patients, 147 patients with available genotyping and UKU scale results were also prescribed 1 or more drugs metabolized by CYP2D6. We did not find any evidence of an effect of the predicted CYP2D6 phenotype on the total burden of adverse drug reactions or in any of the specific symptom domains as measured with the UKU scale among these patients. We also investigated if comedication with 1 or more substances that inhibited the effect of the CYP2D6 enzyme resulted in more reported adverse drug reactions due to phenoconversion. Even though the rate of phenotypic PMs increased from 13 to 38 patients, we did not find any support for increased adverse drug reactions in this group. Conclusions: We did not find that CYP2D6 phenotype could predict the occurrence of adverse drug reactions in patients with depressive disorders in this naturalistic setting. However, information about CYP2D6 genotype may still be important in antidepressant treatment for the selection of appropriate drugs, for dosing recommendations of certain medications, or when the patient is suffering from severe adverse reactions.

Leptin concentrations are increased in subjects treated with clozapine or conventional antipsychotics.
- 2001
-
In: Journal of Clinical Psychiatry. - 0160-6689 .- 1555-2101. ; 62:11, s. 843-848
-
Journal article (peer-reviewed)abstract
- BACKGROUND: Overweight is a considerable clinical problem in patients treated with antipsychotic agents. Recent results suggest that insulin resistance with increased insulin levels is also associated with treatment with the atypical antipsychotic agent clozapine. Leptin is important for the control of body weight and has been proposed to be a link between obesity and the insulin resistance syndrome. This study examined if clozapine-treated subjects and subjects treated with conventional antipsychotics had increased leptin levels compared with the general population and whether there was a gender difference in this respect.METHOD: Clozapine-treated patients (N = 41), patients treated with conventional antipsychotic drugs (N = 62), and healthy subjects from the Northern Sweden Monitoring of Trends and Determinants in Cardiovascular Disease (MONICA) project (N = 189) were investigated with a cross-sectional study design. Weight, body mass index (BMI), and plasma leptin concentrations were measured, and all study subjects were investigated for the presence of diabetes mellitus. Drug treatment, health status, and smoking habits were registered.RESULTS: After adjustment for gender, BMI, smoking habits, age, and diabetes, hyperleptinemia was independently (p < .001) associated with clozapine treatment and with treatment with conventional antipsychotics (p < .005) within a multiple regression analysis. In separate multiple regression analyses, leptin levels were significantly associated with clozapine treatment in men (p = .002) and women (p =.023) and with conventional antipsychotic treatment in men (p = .027) but not in women.CONCLUSION: Treatment with clozapine as well as with conventional antipsychotics is associated with increased levels of circulating leptin. Hyperleptinemia can be an important link in the development of overweight and the insulin resistance syndrome in subjects receiving antipsychotic drugs, especially atypical agents like clozapine.

Karolinska interpersonal violence scale predicts suicide in suicide attempters
- 2010
-
In: Journal of Clinical Psychiatry. - 0160-6689 .- 1555-2101. ; 71:8, s. 1025-32
-
Journal article (peer-reviewed)abstract
- BACKGROUND: Both childhood trauma and violent behavior are important risk factors for suicidal behavior. The aim of the present study was to construct and validate a clinical rating scale that could measure both the exposure to and the expression of violence in childhood and during adult life and to study the ability of the Karolinska Interpersonal Violence Scale (KIVS) to predict ultimate suicide in suicide attempters.METHOD: A total of 161 suicide attempters and 95 healthy volunteers were assessed with the KIVS measuring exposure to violence and expressed violent behavior in childhood (between 6-14 years of age) and during adult life (15 years or older). The Buss-Durkee Hostility Inventory (BDHI), "Urge to act out hostility" subscale from the Hostility and Direction of Hostility Questionnaire (HDHQ), and the Early Experience Questionnaire (EEQ) were used for validation. All patients were followed up for cause of death and a minimum of 4 years from entering in the study.RESULTS: Five patients who committed suicide within 4 years had significantly higher scores in exposure to violence as a child, in expressed violent behavior as an adult, and in KIVS total score compared to survivors. Suicide attempters scored significantly higher compared to healthy volunteers in 3 of the 4 KIVS subscales. There were significant correlations between the subscales measuring exposure to and expression of violent behavior during the life cycle. BDHI, Urge to act out hostility, and EEQ validated the KIVS.CONCLUSIONS: Exposure to violence in childhood and violent behavior in adulthood are risk factors for completed suicide in suicide attempters. Behavioral dysregulation of aggression is important to assess in clinical work. The KIVS is a valuable new tool for case detection and long-term clinical suicide prevention.

Alcohol Use Disorders in Schizophrenia : A National Cohort Study of 12,653 Patients
- 2011
-
In: Journal of Clinical Psychiatry. - 0160-6689 .- 1555-2101. ; 72:6, s. 775-779
-
Journal article (peer-reviewed)abstract
- Background: Comorbid alcohol use disorders (AUDs) in schizophrenia are associated with increased morbidity, more inpatient treatment, and violent offending. It is of clinical importance to identify those with schizophrenia who may go on to develop an alcohol use disorder; however, the risk factors are not well understood. The aim of this study was to identify risk factors for the development of an AUD in patients after they had been diagnosed with schizophrenia. Method: We conducted a retrospective case-control study of 12,653 individuals diagnosed with ICD-defined schizophrenia in Sweden in 1973-2004, using data from national registers. We tested the associations between individual factors (marital status, immigrant status, and previous violent offending), sociodemographic factors (income and education), and parental risk factors (AUDs, psychosis, and violent offending) ICD-defined and AUD development using logistic regression modeling. Results: Over a median follow-up of 17.3 years, 7.6% of patients had at least 1 hospital diagnosis of AUD. After adjustment for gender and age at diagnosis in a multivariate regression model, previous violent offending (OR=2.1; 95% CI, 1.8-2.5), low education (OR=1.3; 95% CI, 1.1-1.5), maternal AUD (OR=1.9; 95% CI, 1.4-2.7), and paternal AUD (OR=1.9; 95% CI, 1.5-2.3) remained independently associated with increased risk of patient AUD. Conclusions: AUDs are a common sequela of schizophrenia. Risk factors that could be identified at the time of first presentation include low educational attainment, previous violent offending, and parental history of AUDs and may inform clinical treatment and follow-up of those most at risk.

- OBJECTIVE: To compare the predictive accuracy of the Suicide Intent Scale (SIS), the Suicide Assessment Scale (SUAS), the Karolinska Interpersonal Violence Scale (KIVS), and the Columbia-Suicide Severity Rating Scale (C-SSRS) for suicide attempts and suicides within 3 and 12 months of an episode of self-harm. METHODS: This prospective multicenter cohort study included patients (N = 804) aged 18-95 years with a recent episode of self-harm assessed in psychiatric emergency settings from April 2012 to April 2016. Suicide attempts and suicides were identified in medical records and in the National Cause of Death Register. Receiver operating characteristic curves were constructed, and accuracy statistics were calculated. A sensitivity of at least 80% combined with a specificity of at least 50% were considered minimally acceptable. RESULTS: At least 1 suicide attempt was recorded for 216 participants during follow-up, and 19 participants died by suicide. The SUAS and C-SSRS were better than chance in classifying the 114 suicide attempts occurring within the first 3 months; a C-SSRS score ≥ 27 yielded a sensitivity/specificity of 79.8%/51.5% (P < .001). During 1-year follow-up, the SUAS and C-SSRS also performed better than chance, but no cutoff on either instrument gave a sensitivity/specificity of ≥ 80%/≥ 50%. The SIS was the only instrument that could classify suicides correctly. At 3 months, the area under the curve (AUC) was 0.94 (95% CI, 0.89-0.99), and a score ≥ 21 predicted suicide with a sensitivity/specificity of 100%/81.9%, based on only 4 suicides. At 1-year follow-up, the AUC was 0.74 (95% CI, 0.61-0.87), and a score ≥ 17 predicted suicide with a sensitivity/specificity of 72.2%/57.9%. CONCLUSIONS: Instruments that predicted nonfatal repeat suicide attempts did not predict suicide and vice versa. With the possible exception of the prediction of suicide by the SIS in a short time frame, the specificity of these instruments was low, giving them a limited relevance in the prediction of suicidal behaviors. © Copyright 2019 Physicians Postgraduate Press, Inc.

- OBJECTIVE: Adverse metabolic effects of atypical antipsychotics have increasingly been recognized. Recently, we found that levels of insulin and triglycerides increased by increasing serum clozapine concentration in clozapine-treated patients. As these insulin and triglyceride elevations probably are drug concentration-dependent, they also would be expected to be drug metabolism-related. The genetically polymorphic cytochromes P450 CYP1A2 and CYP2D6 catalyze the metabolism of clozapine. The aim of this study was to evaluate the impact of CYP1A2 and CYP2D6 polymorphisms on serum drug and metabolite levels and on insulin and triglyceride elevations and insulin resistance in patients receiving clozapine. METHOD: Seventeen clozapine-treated patients were genotyped for CYP1A2 and CYP2D6 by polymerase chain reaction-based methods. Serum concentrations of clozapine and its N-desmethylmetabolite, blood glucose, and serum levels of insulin, C-peptide, triglycerides, and cholesterol were analyzed, and homeostasis model assessment index for insulin resistance (HOMA-IR) was determined. RESULTS: Clozapine and N-desmethylclozapine concentration-to-dose (C/D) ratios were significantly higher in patients carrying 2 CYP1A2 single nucleotide polymorphisms (SNPs), previously suggested to cause low enzyme activity, compared to those with no such SNPs (p < .05). In contrast, clozapine and N-desmethylclozapine C/D ratios were not related to the CYP2D6 genotype. Furthermore, patients with elevated insulin levels more frequently carried CYP1A2*1C and/or *1D alleles, had higher clozapine and N-desmethylclozapine C/D ratios, and had higher lipid levels and HOMA-IR, compared to patients with normal insulin levels (p < .05). CONCLUSION: CYP1A2 variants *1C and *1D seem to be associated with higher serum clozapine concentrations and an increased risk of developing insulin and lipid elevations and insulin resistance on a given dose of clozapine.

- OBJECTIVE: This randomized, 24-week, flexible-dose study compared changes in glucose metabolism in patients with DSM-IV schizophrenia receiving initial exposure to olanzapine, quetiapine, or risperidone. METHOD: The hypothesized primary endpoint was change (baseline to week 24) in area under the curve (AUC) 0- to 2-hour plasma glucose values during an oral glucose tolerance test (OGTT); primary analysis: olanzapine versus quetiapine. Secondary endpoints included mean change in AUC 0- to 2-hour plasma insulin values, insulin sensitivity index, and fasting lipids. The first patient enrolled on April 29, 2004, and the last patient completed the study on October 24, 2005. RESULTS: Mean weight change (kg) over 24 weeks was +3.7 (quetiapine), +4.6 (olanzapine), and +3.6 (risperidone). Based on data from 395 patients (quetiapine, N = 115 [mean dose = 607.0 mg/day], olanzapine, N = 146 [mean dose = 15.2 mg/day], and risperidone, N = 134 [mean dose = 5.2 mg/day]), mean change in AUC 0- to 2-hour glucose value (mg/dL x h) at week 24 was significantly lower for quetiapine versus olanzapine (t = 1.98, df = 377, p = .048). Increases in AUC 0- to 2-hour glucose values were statistically significant with olanzapine (+21.9 mg/dL x h, 95% CI = 11.5 to 32.4 mg/dL x h) and risperidone (+18.8 mg/dL x h, 95% CI = 8.1 to 29.4 mg/dL x h), but not quetiapine (+9.1 mg/dL x h, 95% CI = -2.3 to 20.5 mg/dL x h). AUC 0- to 2-hour insulin values increased statistically significantly with olanzapine (+24.5%, 95% CI = 11.5% to 39.0%), but not with quetiapine or risperidone. Reductions in insulin sensitivity index were statistically significant with olanzapine (-19.1%, 95% CI = -27.9% to -9.3%) and risperidone (-15.8%, 95% CI = -25.1% to -5.4%), but not quetiapine. Total cholesterol and low-density lipoprotein levels increased statistically significantly with olanzapine (+21.1 mg/dL, 95% CI = 13.0 to 29.2 mg/dL, and +20.5 mg/dL, 95% CI = 13.8 to 27.1 mg/dL, respectively) and quetiapine (+13.1 mg/dL, 95% CI = 4.3 to 21.9 mg/dL, and +13.3 mg/dL, 95% CI = 6.1 to 20.5 mg/dL, respectively), but not risperidone. Statistically significant increases in triglycerides (+30.9 mg/dL, 95% CI = 10.9 to 51.0 mg/dL), total cholesterol/high-density lipoprotein (HDL) ratio (0.5, 95% CI = 0.2 to 0.8), and triglyceride/HDL ratio (0.3, 95% CI = 0.0 to 0.6) were observed with olanzapine only. CONCLUSION: The results indicate a significant difference in the change in glucose tolerance during 6 months' treatment with olanzapine versus quetiapine, with significant reductions on olanzapine and risperidone, but not quetiapine; these differential changes were largely explained by changes in insulin sensitivity.

Journal article (peer-reviewed)abstract
- BACKGROUND: This study aimed to assess psychopathology among incarcerated Russian juvenile delinquents in relation to the onset of conduct problems.METHOD: 358 male juvenile delinquents were interviewed from January to September 1999, using the Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version. Early behavior problems, current antisocial behavior, and psychopathology were also assessed through self-reports. The presence of conduct disorder (CD) and other diagnoses was determined according to DSM-IV criteria.RESULTS: 73.2% of the incarcerated youths met criteria for CD. 23.5% of the total sample reported at least 1 criterion for CD being present before the age of 10 years. All participants from this early-onset group fulfilled the criteria for CD. This group also had significantly higher rates of psychopathology, and particularly of externalizing behaviors, as compared with youths whose conduct problems began at or after the age of 10 years.CONCLUSION: Poor psychosocial adaptation and future prognosis in juvenile delinquents with early-onset conduct problems may be related to their greater degree of psychiatric disturbance compared with later-onset delinquent youths. Need for psychiatric treatment should be carefully considered in prevention and rehabilitation efforts for troubled youths.

Impact of Once- Versus Twice-Daily Perphenazine Dosing on Clinical Outcomes: An Analysis of the CATIE Data
- 2014

Journal article (peer-reviewed)abstract
- Objective: The objective of this study was to evaluate the impact of once- versus twice-daily dosing of perphenazine, which has a plasma half-life of 8–12 hours, on clinical outcomes in patients with schizophrenia.Method: Data from phase 1 of the Clinical Antipsychotic Trial of Intervention Effectiveness (CATIE) conducted between January 2001 and December 2004 were used in this post hoc analysis. Patients with schizophrenia (DSM-IV) randomly allocated to treatment with perphenazine were also randomly assigned to once-daily (N = 133) or twice-daily (N = 124) dosing and followed over 18 months. Discontinuation rate and time to discontinuation were used as primary outcomes to compare the 2 groups. The following clinical outcomes were analyzed as secondary measures: efficacy—Positive and Negative Syndrome Scale, Clinical Global Impressions-Severity scale, Calgary Depression Scale for Schizophrenia, and Drug Attitude Inventory and safety/tolerability—Abnormal Involuntary Movement Scale, Barnes Akathisia Rating Scale, Simpson-Angus Scale, and body weight. Data on treatment-emergent adverse events, concomitant psychotropic medications, and medication adherence (pill count and clinician rating scale) were also analyzed for each group.Results: No significant differences were found in any outcome measures between the once-daily and twice-daily dosing groups, which remained the same when using the mean dose of perphenazine as a covariate.Conclusions: Perphenazine is routinely administered in a divided dosage regimen because of its relatively short plasma half-life. However, the present findings challenge such a strategy, suggesting that once-daily represents a viable treatment option. Results are discussed in the context of more recent evidence that challenges the need for high and continuous dopamine D2 receptor blockade to sustain antipsychotic response..

Overlapping Patterns of Suicide Attempts and Non-suicidal Self-Injuries in Adults: A Prospective Clinical Cohort Study
- 2022

In: Journal of Clinical Psychiatry. - : Physicians Postgraduate Press, Inc. - 0160-6689 .- 1555-2101. ; 83:6

Journal article (peer-reviewed)abstract
- Objective: An overlap of non-suicidal self-injuries (NSSIs) and suicide attempts (SAs) is observed in young cohorts, but there are few robust prospective studies for adults. We compared 1-year outcomes in adults with different self-harm patterns: NSSI only, NSSI + SA, and SA only.Methods: 793 patients (67% women) consecutively presenting with NSSI (17%) or SA (83%) at 3 Swedish hospitals took part in face-to-face interviews. Past and current self-harm was characterized by the Columbia-Suicide Severity Rating Scale. Clinical records and national register data were employed to determine 1-year outcomes.Results: At inclusion, over half of the participants had engaged in both NSSI and SA; 41% had SA only and 5%, NSSI only. During follow-up, non-fatal SAs were observed in approximately onethird of the total group (n = 269). Suicides occurred in 2% of those with NSSI + SA; the same proportion was seen in the SA only group. No suicides were observed in those with NSSI only. In a multiple logistic regression analysis, the NSSI + SA pattern was associated with a more than 3-fold risk of subsequent fatal/ non-fatal suicidal behavior compared to "pure" NSSI; risk was not elevated in those with "pure" SA. Neither sex nor age group predicted subsequent suicidal behavior.Conclusions: Switching between behaviors with and without suicidal intent was common in this adult clinical cohort. Risk of subsequent suicidal behavior was tripled in the combined group. Clinicians who assess adults with NSSI must evaluate not only current but also previous episodes when assessing future risk of suicidal behavior.
