Screening for and Management of Opioid Use Disorder in Older Adults in Primary Care.

Opioid use disorder (OUD) is commonly seen in older adults in primary care offices. OUD when left untreated, often leads to overdose deaths, emergency department visits, and hospitalizations due to opioid-related adverse effects, especially respiratory and central nervous system depression. Primary care providers are on the front lines of efforts for its prevention, early detection, and treatment. This includes using the lowest doses of opioids for the shortest possible time for management of pain, routine screening, brief intervention, opioid withdrawal management, prescription of naloxone to prevent overdose death, and treatment with medications and psychosocial interventions for OUD. Referral to addiction treatment centers may be needed in complex cases. This review explores the epidemiology, screening, as well as management of OUD as it pertains to the elderly population.

Experiences of Persons With Serious Mental Illness During the COVID-19 Pandemic.

OBJECTIVE: This study aimed to characterize the experiences of persons with serious mental illness during the COVID-19 pandemic. METHODS: Adults with schizophrenia, bipolar disorder, major depression, or no psychiatric disorder (N=195) were interviewed between July 2020 and January 2021. All were previously enrolled in a cohort study. The interviews focused on mental distress and suicidal thoughts, the impact of the pandemic and pandemic-related worries, tobacco and alcohol use, and access to care. Responses of persons with serious mental illness were compared with responses of those without a psychiatric disorder by using multivariate ordered logistic regression analyses. For a subset of participants, responses about suicidal ideation were compared with their responses prior to the pandemic. RESULTS: Compared with participants with no psychiatric disorder, individuals with schizophrenia were more likely to endorse that they felt overwhelmed or anxious, had difficulty concentrating, or were concerned about medical bills and having enough food; they also reported significantly increased tobacco smoking. Individuals with bipolar disorder also reported more COVID-19-related worries than did participants without a psychiatric disorder. Overall, those with a psychiatric disorder reported more frequent mental distress and more recent missed medical visits and medications than did those with no psychiatric disorder. However, participants with serious mental illness did not report a higher rate of suicidal thoughts compared with their prepandemic responses. CONCLUSIONS: The pandemic poses significant challenges to individuals with serious mental illness in terms of COVID-19-related distress. Psychiatric services should proactively address the emotional distress and worries associated with the pandemic.

Risk factors for natural cause mortality in a cohort of 1494 persons with serious mental illness.

Persons with serious mental illness die on average more than 10 years younger than those in the overall population, mostly due to natural causes. Previous studies have identified predictors of natural cause mortality in this population but few have been prospective studies using clinical variables from in-person evaluations. A cohort of 1494 individuals with schizophrenia, bipolar disorder, or major depressive disorder were assessed at baseline and mortality status was determined from the US National Death Index after up to 20 years of follow-up. Analyses included multivariate Cox proportional hazard models to determine independent predictors of natural cause mortality. A total of 125 (8.4%) individuals died of natural causes. In multivariate models, the strongest predictor of mortality after age was tobacco smoking at baseline with a dose-related effect. Having diabetes, a cardiovascular condition, particularly hypertension, and lower cognitive functioning were also significant risks, along with divorced/separated status. The receipt of gabapentin or fluoxetine also significantly increased mortality risk. Premature death can be reduced by smoking cessation and the improved management of conditions such as hypertension and diabetes.

Exposure to Epstein Barr virus and cognitive functioning in individuals with schizophrenia.

Cognitive deficits are a central feature of schizophrenia whose etiology is not fully understood. Epstein Barr Virus (EBV) is a potentially neurotropic infectious agent that can generate persistent infections with immunomodulatory effects. Previous studies have found an association between EBV antibodies and cognitive functioning in different populations, but there has been limited investigation in schizophrenia. In this study, 84 individuals with schizophrenia were administered a comprehensive neuropsychological battery, the MATRICS Consensus Cognitive Battery (MCCB). Participants also provided a blood sample, from which antibodies to the EBV whole virion and specific proteins were measured. Multivariate models were constructed to determine the association between these antibodies and cognitive performance on the MCCB overall and domain scores. Using these models, we found a significant association between the MCCB overall percent composite score and level of antibodies to the EBV Nuclear Antigen-1 (EBNA-1) protein, the Viral Capsid Antigen (VCA) protein, and the EBV whole virion. A significant association was also found for the MCCB social cognition domain with the level of antibodies to the EBV Nuclear Antigen-1 (EBNA-1) protein, the Viral Capsid Antigen (VCA) protein, and the EBV whole virion. In all cases, a higher level of antibodies was associated with a lower level cognitive performance. These findings suggest that exposure to EBV may contribute to cognitive deficits in schizophrenia, a finding which may have implications for new methods of prevention and treatment.

Atypical immune response to Epstein-Barr virus in major depressive disorder.

BACKGROUND: An atypical immune response to Epstein-Barr virus (EBV) infection has been associated with several complex diseases including schizophrenia. The etiology of MDD is unclear; host immune response to EBV infection could play a role. METHODS: We utilized solid phase immunoassays and western blots to measure antibodies to EBV virions, specific viral proteins, and 5 other herpesviruses in 87 individuals with MDD and 312 control individuals. RESULTS: Individuals with MDD had significantly reduced levels of reactivity to EBV Nuclear Antigen-1. Quantitative levels of antibodies to EBV virions and Viral Capsid Antigen did not differ between groups. Individuals with decreased levels of anti-Nuclear Antigen-1, or elevated levels of anti-virion had increased odds of being in the MDD group. The odds of MDD were elevated in individuals who had the combination of high levels of anti-virion and low levels of anti-Nuclear Antigen-1 (OR =13.6). Western blot analysis corroborated decreased reactivity to Nuclear Antigen-1 in the MDD group and revealed altered levels of antibodies to other EBV proteins. There was a trend towards decreased levels of antibodies to varicella virus in the group of individuals with MDD. LIMITATIONS: The MDD sample size was relatively small. There could be unmeasured factors that account for the association between MDD and the immune response to EBV. CONCLUSIONS: Individuals with MDD have altered levels and patterns of antibodies to EBV antigens. This atypical response could contribute to the immunopathology of MDD. Therapeutic interventions available for treatment of EBV infection could potentially be of benefit in MDD.

Reducing opioid use for chronic pain in older adults.

PURPOSE: Implementation of the SAFE PAIN algorithm for reducing opioid use for chronic pain in older adults is described. SUMMARY: A multidisciplinary team at Sheppard Pratt Health System, the largest private provider of psychiatric care in Maryland, used lean methodology to identify the root causes for noncompliance to evidence-based practices for patients in the geropsychiatry unit treated for osteoarthritis or chronic back pain. The team collaborated to develop a facility-specific treatment algorithm, called SAFE PAIN (Sheppard Pratt Health System Algorithm For Elderly Patient Centered Analgesia Interdisciplinary Nagara), was based on the Center for Disease Control and Prevention's evidence-based recommendations that included nonpharmacologic interventions as a first-line therapy for patients with osteoarthritis or chronic back pain. Rates of prescribing new opioids and prescribing evidence-based alternative medications via the SAFE PAIN algorithm were evaluated from March 1 to September 30, 2017 and compared with baseline (2012-2016). The lean methodology interventions led to zero new opioid orders during the study period, a significant decrease compared with previous years (p < 0.01). The rates of prescribing evidence-based alternative medications increased significantly from the baseline period to postimplementation (p < 0.01). Lean methodology interventions also decreased waste in several processes. CONCLUSION: The prescribing rate of new opioids for osteoarthritis and chronic back pain decreased and the prescribing rate for evidence-based medications increased after implementation of the SAFE PAIN algorithm in a geropsychiatry unit.

Nitrated meat products are associated with suicide behavior in psychiatric patients.

There has been little previous study of the association between dietary factors and suicide. The association between food exposures and suicide attempt history was investigated in a sample of 270 individuals with schizophrenia, bipolar disorder, or major depressive disorder. Individuals who had a suicide attempt history were almost 3 times as likely to report eating cured meat, typically prepared with added nitrates, compared to patients without a suicide attempt history, adjusting for demographic and clinical variables. A suicide attempt history was 6 times greater in those who in addition were cigarette smokers and had a history of substance abuse compared to those who did not have any of these risk factors. If dietary factors were shown to affect suicide risk, an additional method of risk reduction would be available which could be widely disseminated to address this major public health problem.

Schizophrenia is Associated With an Aberrant Immune Response to Epstein-Barr Virus.

BACKGROUND: Epstein-Barr virus (EBV) is a highly prevalent human herpesvirus capable of infecting the central nervous system and establishing persistent infection. METHODS: We employed solid phase immunoassay techniques to measure immunoglobulin G (IgG) class antibodies to EBV virions and defined proteins in 432 individuals with schizophrenia and 311 individuals without a history of a psychiatric disorder. Western blot testing was performed to document reactivity to specific EBV proteins. Polygenic risk for schizophrenia was calculated from genome sequencing arrays. Levels of antibodies between the groups were compared by multivariate analyses incorporating clinical, genetic, and demographic measures. RESULTS: Individuals with schizophrenia had marked elevations in the levels of antibodies to EBV virions as compared to the control population. Further analyses indicated increased levels of reactivity to EBV-viral capsid antibody (VCA) but not to EBV nuclear antigen-1 (EBNA-1) or to other human herpesviruses. Western blot analysis confirmed increased reactivity to VCA proteins in the group of individuals with schizophrenia and documented a lack of increased levels of antibodies to EBNA-1. Genetic analyses indicated an additive effect of increased levels of antibodies to EBV virions and genetic susceptibility to schizophrenia, with individuals with elevated levels of both type of markers having a greater than 8.5-fold odds of a schizophrenia diagnosis. CONCLUSIONS: Individuals with schizophrenia have increased levels of antibodies to some but not all EBV proteins indicating an aberrant response to EBV infection. This aberrant response may contribute to the immunopathology of schizophrenia and related disorders.

Adjunctive probiotic microorganisms to prevent rehospitalization in patients with acute mania: A randomized controlled trial.

OBJECTIVE: Immunological abnormalities play a role in the pathophysiology of mania and have been associated with relapse. Probiotic organisms such as Lactobacilli and Bifidobacteria modulate inflammation in humans and animal models. The trial examined whether the administration of probiotic organisms prevents psychiatric rehospitalizations in patients recently discharged following hospitalization for mania. METHODS: Patients hospitalized for mania (N = 66) were randomized after discharge to receive 24 weeks of adjunctive probiotics (Lactobacillus rhamnosus strain GG and Bifidobacterium animalis subsp. lactis strain Bb12) or adjunctive placebo in a parallel two-group design format. The effect of treatment group on the risk of rehospitalization was calculated using Cox regression models. The modulating effect of systemic inflammation was measured employing an inflammation score based on immunoglobulin levels directed at previously defined antigens. RESULTS: During the 24-week observation period there were a total of 24 rehospitalizations in the 33 individuals who received placebo and eight rehospitalizations in the 33 individuals who received the probiotics (z = 2.63, P = .009). Hazard functions indicated that the administration of the probiotics was associated with a significant advantage in time to all psychiatric rehospitalizations (hazard ratio [HR] = 0.26, 95% confidence interval [CI] 0.10, .69; P = .007). Probiotic treatment also resulted in fewer days rehospitalized (mean 8.3 vs 2.8 days for placebo and probiotic treatment, respectively; χ2  = 5.17, P = .017). The effect of the probiotic treatment on the prevention of rehospitalization was increased in individuals with elevated levels of systemic inflammation at baseline. CONCLUSION: Probiotic supplementation is associated with a lower rate of rehospitalization in patients who have been recently discharged following hospitalization for mania.

Clinical and Serological Predictors of Suicide in Schizophrenia and Major Mood Disorders.

Persons with serious mental illness are at high risk for suicide, but this outcome is difficult to predict. Serological markers may help to identify suicide risk. We prospectively assessed 733 persons with a schizophrenia spectrum disorder, 483 with bipolar disorder, and 76 with major depressive disorder for an average of 8.15 years. The initial evaluation consisted of clinical and demographic data as well as a blood samples from which immunoglobulin G antibodies to herpes viruses and Toxoplasma gondii were measured. Suicide was determined using data from the National Death Index. Cox proportional hazard regression models examined the role of baseline variables on suicide outcomes. Suicide was associated with male sex, divorced/separated status, Caucasian race, and elevated levels of antibodies to Cytomegalovirus (CMV). Increasing levels of CMV antibodies were associated with increasing hazard ratios for suicide. The identification of serological variables associated with suicide might provide more personalized methods for suicide prevention.

Cigarette Smoking by Patients With Serious Mental Illness, 1999-2016: An Increasing Disparity.

OBJECTIVE: This study examined the prevalence of cigarette smoking and the quantity of cigarettes consumed by individuals with schizophrenia and bipolar disorder and those without a psychiatric disorder in the period 1999-2016. METHOD: A total of 1,938 individuals provided information about their cigarette smoking at enrollment into a research study for which they were selected without regard to their smoking status. Differences among groups and trends over time in smoking and cigarette consumption were examined by using multivariate models. RESULTS: Marked differences between groups were noted in the prevalence of smoking and in the quantity of cigarettes consumed. Overall, 62% of individuals with schizophrenia, 37% with bipolar disorder, and 17% of participants without a psychiatric disorder (control group) reported that they were current smokers. Smoking prevalence decreased over time in the sample primarily because of the decrease in smoking in the control group. Smokers with schizophrenia and with bipolar disorder smoked more cigarettes per day than smokers in the control group. Among smokers in all the groups, the quantity of cigarettes consumed per day declined significantly over the study period. Smoking was significantly associated with older age, less education, Caucasian race, and male gender. CONCLUSIONS: The prevalence of smoking has remained alarmingly high among individuals with schizophrenia and bipolar disorder, and the disparity with those without psychiatric disorders and with the general population is increasing. Additional measures are urgently needed to address this major public health problem.

The association between immune markers and recent suicide attempts in patients with serious mental illness: A pilot study.

Previous studies have identified elevations in markers of gastrointestinal inflammation in schizophrenia and mood disorders but studies have not measured the association between these markers and recent suicide attempts. We assessed 210 patients receiving treatment for schizophrenia, bipolar disorder, or major depression. We employed the Columbia Suicide Severity Rating Scale to identify recent and lifetime suicide attempts (actual, aborted, and interrupted). Psychiatric participants and a control group of 72 individuals without a psychiatric disorder had a blood sample drawn from which were measured specific markers of gastrointestinal inflammation and also C-Reactive protein (CRP). A total of 20 (10%) of psychiatric participants had a suicide attempt in the previous one month and 95 (45%) an attempt during their lifetime but not in the previous one month. The recent attempters had significantly elevated levels of antibodies to yeast mannan from Saccharomyces cerevisiae (ASCA), the food antigen gliadin, and bacterial lipopolysaccharide (LPS) compared with the non-psychiatric group when adjusting for demographic and clinical variables. These markers were not elevated in individuals with a past, but not recent, suicide attempt history. Our study indicates that there is evidence of gastrointestinal inflammation in some individuals who have had a recent suicide attempt.

Probiotic normalization of Candida albicans in schizophrenia: A randomized, placebo-controlled, longitudinal pilot study.

The molecules and pathways of the gut-brain axis represent new targets for developing methods to diagnose and treat psychiatric disorders. Manipulation of the gut microbiome with probiotics may be a therapeutic strategy with the potential to relieve gastrointestinal (GI) comorbidities and improve psychiatric symptoms. Candida albicans and Saccharomyces cerevisiae, commensal yeast species, can be imbalanced in the unhealthy human microbiome, and these fungal exposures were previously found elevated in schizophrenia. In a longitudinal, double-blind, placebo-controlled, pilot investigation of 56 outpatients with schizophrenia, we examined the impact of probiotic treatment on yeast antibody levels, and the relationship between treatment and antibody levels on bowel discomfort and psychiatric symptoms. We found that probiotic treatment significantly reduced C. albicans antibodies over the 14-week study period in males, but not in females. Antibody levels of S. cerevisiae were not altered in either treatment group. The highest levels of bowel discomfort over time occurred in C. albicans-seropositive males receiving the placebo. We observed trends towards improvement in positive psychiatric symptoms in males treated with probiotics who were seronegative for C. albicans. Results from this pilot study hint at an association of C. albicans seropositivity with worse positive psychiatric symptoms, which was confirmed in a larger cohort of 384 males with schizophrenia. In conclusion, the administration of probiotics may help normalize C. albicans antibody levels and C. albicans-associated gut discomfort in many male individuals. Studies with larger sample sizes are warranted to address the role of probiotics in correcting C. albicans-associated psychiatric symptoms.

Suicide attempts and markers of immune response in individuals with serious mental illness.

Previous studies have identified elevations in antibodies to Toxoplasma gondii in individuals with a history of suicide attempts but studies have not measured the association between suicide attempts and a panel of antibody markers. We assessed 162 patients receiving treatment for schizophrenia, bipolar disorder, or major depression on the Columbia Suicide Severity Rating Scale for suicide attempt history and other clinical measures. All participants had a blood sample drawn from which were measured antibodies to Toxoplasma gondii and other neurotropic infectious agents. A total of 72 (44%) of participants had a lifetime suicide attempt; these individuals had elevated levels of IgM class antibodies to Toxoplasma gondii and Cytomegalovirus (CMV). We also found an association between the levels of these antibodies and the number of suicide attempts. There was a particularly strong odds of a suicide attempt history in individuals who had elevated levels of IgM antibodies to both Toxoplasma gondii and to CMV suggesting an additive risk associated with the antibodies. These findings remained significant when adjusting for current cigarette smoking and history of drug/alcohol use which were also associated with suicide attempts. We did not find an association between a suicide attempt history and IgG class antibodies to Toxoplasma gondii, CMV, or IgM or IgG antibodies to the Epstein Barr Virus or other antigens tested. The identification of blood-based antibody markers should provide for more personalized methods for the assessment and treatment, and ultimately prevention, of suicide attempts in individuals with serious mental illnesses.

Individuals hospitalized with acute mania have increased exposure to antimicrobial medications.

OBJECTIVES: We have preciously documented that many individuals with acute mania have immune activation. However, the sources of immune activation have not been identified. We investigated whether individuals hospitalized with acute mania have evidence of bacterial infections as determined by the prescription of systemic antimicrobial agents. METHODS: We assessed the recent prescription of systemic antimicrobial medications and the site of presumed bacterial infection in 234 individuals hospitalized for acute mania in either an inpatient unit or a day hospital. We also assessed individuals hospitalized for other psychiatric disorders (n=368) and controls (n=555). We employed logistic regression models to compare the rates of antibiotic prescription in individuals with the different diagnoses, employing demographic variables as covariates. RESULTS: We found that individuals hospitalized with acute mania had a substantially increased rate of recent antimicrobial prescription, defined as exposure within three days of ascertainment (adjusted odds ratio=5.5, 95% confidence interval: 2.2-14.1, P<.0002). Overall, a total of 18 of the 234 (7.7%) individuals hospitalized for acute mania were prescribed antibiotics as opposed to seven of 555 (1.3%) controls. The prescription of antibiotics was associated with being on an inpatient unit as opposed to being in the day hospital, and having increased mania symptom severity but not with other clinical ratings, demographic variables, or psychiatric medications. Hospitalization for other psychiatric disorders was not associated with the recent prescription of antimicrobial medications. The urinary tract was the most common site of infection in women, while the respiratory tract and mucosal surfaces were the most common sites in men. CONCLUSIONS: Individuals hospitalized with acute mania have a markedly increased rate of bacterial infections, as evidenced by the recent prescription of antimicrobial agents. The prevention and effective treatment of bacterial infections may be important interventions for the management of individuals with mania.

Candida albicans exposures, sex specificity and cognitive deficits in schizophrenia and bipolar disorder.

Immune aberrations in schizophrenia and bipolar disorder have led to the hypotheses that infectious agents or corresponding immune responses might contribute to psychiatric etiopathogeneses. We investigated case-control differences in exposure to the opportunistic fungal pathogen, Candida albicans, and examined associations with cognition, medication, lifestyle, and somatic conditions. We quantified C. albicans IgG antibodies in two cohorts totaling 947 individuals and evaluated odds ratios (OR) of exposure with psychiatric disorder using multivariate regressions. The case-control cohort included 261 with schizophrenia, 270 with bipolar disorder, and 277 non-psychiatric controls; the second included 139 with first-episode schizophrenia, 78 of whom were antipsychotic naive. No differences in C. albicans exposures were found until diagnostic groups were stratified by sex. In males, C. albicans seropositivity conferred increased odds for a schizophrenia diagnosis (OR 2.04-9.53, P⩽0.0001). In females, C. albicans seropositivity conferred increased odds for lower cognitive scores on Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) in schizophrenia (OR 1.12, P⩽0.004), with significant decreases on memory modules for both disorders (P⩽0.0007-0.03). C. albicans IgG levels were not impacted by antipsychotic medications. Gastrointestinal (GI) disturbances were associated with elevated C. albicans in males with schizophrenia and females with bipolar disorder (P⩽0.009-0.02). C. albicans exposure was associated with homelessness in bipolar males (P⩽0.0015). In conclusion, sex-specific C. albicans immune responses were evident in psychiatric disorder subsets. Inquiry regarding C. albicans infection or symptoms may expedite amelioration of this treatable comorbid condition. Yeast exposure as a risk factor for schizophrenia and its associated cognitive and GI effects require further investigation including the possible contribution of gut-brain mechanisms.
