The influence of chronic inflammation on the illnesscourse of bipolar disorder: A longitudinal study. J Psychiatr Res 2024; 174:258-262. [PMID: 38670061 DOI: 10.1016/j.jpsychires.2024.04.024] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/15/2023] [Revised: 04/02/2024] [Accepted: 04/09/2024] [Indexed: 04/28/2024]
Abstract
INTRODUCTION C-reactive protein (CRP) is a systemic inflammatory marker, which indicates systemic inflammatory processes It is involved in different inflammatory processes of the body and is a reliable marker for the general inflammatory state of the body. High sensitive CRP seems to play a key role as a state and trait marker of bipolar disorder (BD). In the current study, we tried to determine the long-term effect of CRP levels on clinical symptoms and illness course of bipolar disorder. METHODS For the current study, we examined 106 patients with BD for a period of four years. Participants underwent a clinical screening for depressive and manic episodes with the Hamilton Depression Scale (HAMD) and the Young Mania Rating Score (YMRS) and a serological diagnostic for inflammatory parameters every six months, thus leading to 8 measurement times in total. Patients with the presence of severe medical or neurological comorbidities such as active cancer, chronic obstructive lung disease, rheumatoid arthritis, systemic lupus erythematosus, Alzheimer's disease, Parkinson's disease, Huntington's disease or multiple sclerosis and acute infections were not included in the study. RESULTS In our sample, 26% showed a mean hsCRP above 5 mg/dl. Those patients showed a significantly higher mean YMRS score than those with a mean hsCRP under 5 mg/dl during our observation period. Regarding HAMD there was no significant difference in hsCRP values. The existence of lithium treatment showed no significant influence on mean hsCRP levels between the start and endpoint. CONCLUSION Individuals who were exposed to a higher level of inflammation over time suffered from more manic symptoms in this period. These findings underline the hypothesis that inflammatory processes have an accumulative influence on the illness course of BD, especially concerning manic symptoms and episodes.

Serum neurofilament light as a potential marker of illness duration in bipolar disorder. J Affect Disord 2024; 350:366-371.

Abstract
INTRODUCTION Investigation on specific biomarkers for diagnostic or prognostic usage in mental diseases and especially bipolar disorder BD seems to be one outstanding field in current research. Serum neurofilament light (sNfL), a marker for neuro-axonal injury, is increased in various acute and chronic neurological disorders, but also neuro-psychiatric conditions, including affective disorders. The aim of our study was to determine a potential relation between a neuron-specific marker like sNfL and different clinical states of BD. METHODS In the current investigation, 51 patients with BD and 35 HC were included. Mood ratings with the Hamilton depression scale (HAMD) and the Young mania rating scale (YMRS) have been included. Illness duration was defined as the period from the time of diagnosis out of self-report and medical records. sNFL was quantified by a commercial ultrasensitive single molecule array (Simoa). RESULTS There was a significant positive correlation between the number of manic episodes in the past and sNfL, controlled for age and duration of illness. (R = 0.49, p = 0.03) Depressive episodes were not associated to sNfL values. (R = 0.311, p = n.s.) Patients with >3 years of illness duration showed significantly higher levels of sNfL (M18.59; SD 11.89) than patients with shorter illness duration (M = 12.38, p = 0.03) and HC (M = 11.35, p = 0.02). Patients with <3 years of illness and HC did not differ significantly in sNfL levels. DISCUSSION Interestingly, individuals with BD and HC did not differ in sNFL levels in general. Nevertheless, looking at the BD cohort more specifically, we found that individuals with BD with longer duration of illness (>3 years) had higher levels of sNfL than those with an illness duration below 3 years. Our results confirm previous reports on the relation of neuro-axonal injury as evidenced by sNfL and illness specific variables in bipolar disorder. Further studies are needed to clarify if sNfL may predict the disease course and/or indicated response to treatment regimes.

BMC Public Health 2024; 24:894. [PMID: 38532390 PMCID: PMC10964590 DOI: 10.1186/s12889-024-18349-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2023] [Accepted: 03/13/2024] [Indexed: 03/28/2024] Open
Abstract
BACKGROUND Obesity is a global public health concern. The goal of this study was to see if eating habits could mediate the relationship between psychological distress and weight maintenance in a population with a history of weight cycling. METHODS A 3-month outpatient intervention consisting of a diet and exercise program was provided to 153 participants. Psychological distress, appetite, and behavior were assessed at the beginning and end of the study. Anthropometric measurements were taken at baseline and six months. RESULTS After the structural equation model was developed, it was discovered that the psychological status of people with obesity and weight cycling histories correlated with the weight loss outcome effect (three and six months). This effect was mediated by factors related to eating behavior. Associative psychological factors had a direct effect on eating behavior (three months: β = 0.181, 95% CI: 0.055-0.310; six months: β = 0.182, 95% CI: 0.039-0.332) and appetite had a direct effect on eating behavior (three months: β = 0.600, 95% CI: 0.514-0.717; six months: β = 0.581, 95% CI: 0.457-0.713), both of which were significant (p < 0.01). At three months, psychological distress has a more substantial positive impact on weight change, with eating behavior acting as a partial mediator. At six months, there was no support for appetite's moderating role in eating behavior. CONCLUSIONS The findings suggest that psychological interventions should be strengthened to improve weight loss effectiveness, particularly in participants with a history of weight cycling, making weight loss more complicated and prone to rebound. CLINICAL TRIAL REGISTRATION The study has been registered in Clinical Trials (NCT05311462).

Abstract
A relevant comorbidity of bipolar disorder (BD) is eating disorders (EDs). Crossed vulnerability factors as eating disorder-specific symptoms (EDSSs) may trigger the onset of both disorders in either direction. The Structured Inventory for Anorexic and Bulimic Eating Disorders for Self-Report was used to examine the occurrence of EDs in euthymic/subsyndromal individuals with BD ( n = 86) and healthy controls ( n = 86) matched for age and sex. Furthermore, we explored EDSSs with the subscales "general psychopathology and social integration," "bulimic symptoms," "body image and slimness ideal," "sexuality and body weight," "counteract," and "atypical binge." Higher rates of all EDSSs were reported in BD. Younger individuals with BD showed higher expression in "bulimic symptoms," "body image and slimness ideal," and "atypical binge" subscales. No participants fulfilled ED diagnosis. The findings show a link between EDSS and BD. Clinicians should pay attention to a multimodal intervention, considering risk factors, investigating eating habits and ED associated behaviors.

Nutrition, Overweight, and Cognition in Euthymic Bipolar Individuals Compared to Healthy Controls. Nutrients 2022; 14:nu14061176.

Abstract
Bipolar disorder (BD) is associated with impairments in cognitive functions, in which metabolic factors, e.g., overweight, seem to play a significant role. The aim of this study was to investigate the association between nutritional factors and cognitive performance in euthymic individuals with BD. A study cohort of 56 euthymic individuals with BD was compared to a sample of 53 mentally healthy controls. To assess cognitive function, the following tests were applied: California Verbal Learning Test, Trail Making Test A/B, d2 Test of Attention-Revised, and Stroop’s Color-Word Interference Test. Furthermore, a 4-day food record was processed to evaluate dietary intake of macronutrients, specific micronutrients, and food diversity. Body mass index and waist to height ratio were calculated to assess overweight and central obesity. Results showed no nutritional differences between individuals with BD and controls. Individuals with BD performed worse in the d2 test than controls. Hierarchical regression analyses yielded no association between cognitive and nutritional parameters. However, waist to height ratio was negatively correlated with almost all cognitive tests. Central obesity seems to affect cognitive functioning in BD, while the lack of finding differences in nutritional data might be due to problems when collecting data and the small sample size. Consequently, further studies focusing on objectively measuring food intake with adequate sample size are needed.

Abstract
Metabolic syndrome (MetS) and its component factors, obesity, hypertension, dyslipidaemia and insulin resistance, have shown a bidirectional relationship with the prevalence and severity of bipolar disorder (BD). A systematic search of electronic databases (Pubmed, PsycINFO, clinicaltrials.gov) was conducted to explore and integrate current evidence about the role of MetS and its component factors with clinical outcomes of BD. Thirty-four articles met the inclusion criteria. Studies were grouped by the metabolic factors assessed, which included MetS, obesity and body mass index (BMI), dyslipidaemia, impaired glucose metabolism (IGM), diabetes mellitus and hypertension. They were then classified according to outcomes such as course of episodes, rapid cycling, suicidal behavior, treatment response, and global and cognitive functioning. Although current evidence remains controversial in most aspects of clinical outcomes, metabolic risk factors could alter the course of BD, with worse global functioning, poorer treatment response and a chronic course of illness, as well as enhancing rapid cycling. Further research is needed to elucidate the role of each risk factor in the mentioned outcomes.

Abstract
Patients with bipolar disorder (BIP) have a high risk of cardiovascular disease (CVD), despite considerable individual variation. The mechanisms underlying comorbid CVD in BIP remain largely unknown. We investigated polygenic overlap between BIP and CVD phenotypes, including CVD risk factors and coronary artery disease (CAD). We analyzed large genome-wide association studies of BIP (n = 51,710) and CVD phenotypes (n = 159,208-795,640), using bivariate causal mixture model (MiXeR), which estimates the total amount of shared genetic variants, and conjunctional false discovery rate (FDR), which identifies specific overlapping loci. MiXeR revealed polygenic overlap between BIP and body mass index (BMI) (82%), diastolic and systolic blood pressure (20-22%) and CAD (11%) despite insignificant genetic correlations. Using conjunctional FDR < 0.05, we identified 129 shared loci between BIP and CVD phenotypes, mainly BMI (n = 69), systolic (n = 53), and diastolic (n = 53) blood pressure, of which 22 are novel BIP loci. There was a pattern of mixed effect directions of the shared loci between BIP and CVD phenotypes. Functional analyses indicated that the shared loci are linked to brain-expressed genes and involved in neurodevelopment, lipid metabolism, chromatin assembly/disassembly and intracellular processes. Altogether, the study revealed extensive polygenic overlap between BIP and comorbid CVD, implicating shared molecular genetic mechanisms. The mixed effect directions of the shared loci suggest variation in genetic susceptibility to CVD across BIP subgroups, which may underlie the heterogeneity of CVD comorbidity in BIP patients. The findings suggest more focus on targeted lifestyle interventions and personalized pharmacological treatment to reduce CVD comorbidity in BIP.

The association between anti-inflammatory effects of long-term lithium treatment and illness course in Bipolar Disorder. J Affect Disord 2021; 281:228-234. [PMID: 33338840 DOI: 10.1016/j.jad.2020.11.063] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/17/2020] [Revised: 10/15/2020] [Accepted: 11/08/2020] [Indexed: 11/21/2022]
Abstract
INTRODUCTION Altered levels of acute-phase proteins are often described in different conditions in BD. Nevertheless, data on the association between lithium treatment and inflammatory markers in the long-term course of BD are still missing. The aim of the study was to examine the long-term course of BD concerning long-term lithium treatment, chronic inflammatory processes and symptom progression. Furthermore, the association between duration of lithium treatment and levels of hsCRP was explored. METHODS 267 individuals (males= 139, females= 128) with BD were included. Duration of lithium treatment as well as symptom progression, defined as the increase in severity of symptoms, number of episodes a year and duration of episodes within a period of 1.5 years in the past and hsCRP were evaluated. RESULTS Male individuals with symptom progression over time had significantly lower duration of lithium treatment compared to individuals without symptoms progression (U= 47.4, p=.037). There were significantly higher levels of hsCRP in male individuals with symptom progression compared to males without symptom progression (U= 47.5, p=.027). Further, there was a significant negative correlation between the duration of lithium treatment and hsCRP levels in the whole sample (r= -.276, p<.05). CONCLUSION Our results show that an altered inflammatory state may be associated with a more severe illness course in BD. Further, a longer duration of lithium treatment may be associated with lower symptom progression. The shown association between hsCRP-levels and lithium treatment duration suggests a potential anti-inflammatory effect of lithium as a mediator of its significant positive outcome effect in BD.

Abstract
BACKGROUND There are scarce and discrepant data about the prevalence and correlates of co-occurring eating disorders (EDs) among people with a primary diagnosis of bipolar disorder (BD), and vice-versa, compelling a systematic review and meta-analysis on the matter. METHODS MEDLINE/PsycINFO databases were systematically searched for original studies documenting BD⇌ED comorbidity across the lifespan, from inception up until April 20th, 2020. Random-effects meta-analysis and meta-regression analyses were conducted, accounting for multiple moderators. RESULTS Thirty-six studies involved 15,084 primary BD patients. Eleven studies encompassed 15,146 people with primary EDs. Binge eating disorder (BED) occurred in 12.5% (95%C.I.=9.4-16.6%, I2=93.48%) of BDs, while 9.1% (95%C.I.=3.3-22.6%) of BEDs endorsed BD. Bulimia Nervosa (BN) occurred in 7.4% (95%C.I.=6-10%) of people with BD, whereas 6.7% (95%C.I.=12-29.2%) of subjects with BN had a diagnosis of BD. Anorexia Nervosa (AN) occurred in 3.8% (95%C.I.=2-6%) of people with BDs; 2% (95%C.I.=1-2%) of BD patients had a diagnosis of AN. Overall, BD patients with EDs had higher odds of being female vs. non-ED controls. Several moderators yielded statistically significant differences both within- and between different types of BDs and EDs. LIMITATIONS Scant longitudinal studies, especially across different EDs and pediatric samples. High heterogeneity despite subgroup comparisons. Limited discrimination of the quality of the evidence. CONCLUSIONS The rates of BD⇌ED comorbidity vary across different diagnostic groups, more than they do according to the "direction" of BD⇌ED. Further primary studies should focus on the risks, chronology, clinical impact, and management of the onset of intertwined BD⇌ED across different ages, promoting a continuum approach.

The Relationship Between Food Craving, Appetite-Related Hormones and Clinical Parameters in Bipolar Disorder. Nutrients 2020; 13:nu13010076. [PMID: 33383670 DOI: 10.3390/nu13010076] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2020] [Revised: 12/20/2020] [Accepted: 12/23/2020] [Indexed: 12/24/2022] Open
Abstract
Obesity and weight gain in bipolar disorder (BD) have multifactorial underlying causes such as medication side effects, atypical depressive symptomatology, genetic variants, and disturbances in the neuro-endocrinal system. Therefore, we aim to explore the associations between food craving (FC), clinical parameters, psychotropic medication, and appetite-related hormones. In this cross-sectional investigation, 139 individuals with BD and 93 healthy controls (HC) completed the food craving inventory (FCI). In addition, blood samples (including leptin and acylated ghrelin) were analyzed and sociodemographic and anthropometric data were collected. Individuals with BD reported higher frequencies of total FC as well as craving for fat and fast food than HC. Additionally, we found a significant negative correlation between FC and ghrelin levels in BD. Smokers with BD reported significantly more craving for high fat foods than non-smokers. Age was significantly associated with FC independent of group. Individuals with BD taking olanzapine and quetiapine reported higher frequencies of craving for sweet food, while patients currently taking lithium reported less total FC compared to those without lithium therapy. Likewise, patients currently taking valproate reported less total FC and less craving for sweets than those not taking valproate. FC appears to be of clinical relevance in individuals with BD. Contrary to previous data, this does not seem to be a female phenomenon only and might encompass more than the specific craving for carbohydrates. Although due to the cross sectional design, causality cannot be determined, the association between depressive symptomatology and fast food craving warrants further research.

Prolonged functional cerebral asymmetry as a consequence of dysfunctional parvocellular paraventricular hypothalamic nucleus signaling: An integrative model for the pathophysiology of bipolar disorder.

Abstract
Approximately 45 million people worldwide are diagnosed with bipolar disorder (BD). While there are many known risk factors and models of the pathologic processes influencing BD, the exact neurologic underpinnings of BD are unknown. We attempt to integrate the existing literature and create a unifying hypothesis regarding the pathophysiology of BD with the hope that a concrete model may potentially facilitate more specific diagnosis, prevention, and treatment of BD in the future. We hypothesize that dysfunctional signaling from the parvocellular neurons of the paraventricular hypothalamic nucleus (PVN) results in the clinical presentation of BD. Functional damage to this nucleus and its signaling pathways may be mediated by myriad factors (e.g. immune dysregulation and auto-immune processes, polygenetic variation, dysfunctional interhemispheric connections, and impaired or overactivated hypothalamic axes) which could help explain the wide variety of clinical presentations along the BD spectrum. The neurons of the PVN regulate ultradian rhythms, which are observed in cyclic variations in healthy individuals, and mediate changes in functional hemispheric lateralization. Theoretically, dysfunctional PVN signaling results in prolonged functional hemispheric dominance. In this model, prolonged right hemispheric dominance leads to depressive symptoms, whereas left hemispheric dominance correlated to the clinical picture of mania. Subsequently, physiologic processes that increase signaling through the PVN (hypothalamic-pituitaryadrenal axis, hypothalamic- pituitary-gonadal axis, and hypothalamic-pituitary-thyroid axis activity, suprachiasmatic nucleus pathways) as well as, neuro-endocrine induced excito-toxicity, auto-immune and inflammatory flairs may induce mood episodes in susceptible individuals. Potentially, ultradian rhythms slowing with age, in combination with changes in hypothalamic axes and maturation of neural circuitry, accounts for BD clinically presenting more frequently in young adulthood than later in life.

J Diabetes Investig 2020; 12:625-632. [PMID: 32745374 PMCID: PMC8015818 DOI: 10.1111/jdi.13380] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/19/2020] [Revised: 07/14/2020] [Accepted: 07/27/2020] [Indexed: 12/13/2022] Open
Abstract
AIMS/INTRODUCTION In this meta-analysis, we aimed to explore the association between bodyweight cycling (weight fluctuation) and the risk of developing diabetes. MATERIALS AND METHODS We analyzed data from eligible cohort studies that assessed the association between weight cycling in adults and the risk of developing diabetes from online databases PubMed, Cochrane Library and EMBASE databases (1966 to April 2020). We pooled data using relative risks (RRs) with a random effects model. RESULTS A total of 14 studies involving 253,766 participants, including 8,904 diabetes events, were included. One study included eight independent reports, resulting in 21 reports in 14 studies. Summary analysis showed that individuals who suffered weight cycling had a higher risk of diabetes (RR 1.23. 95% confidence interval 1.07-1.41; P = 0.003). However, the association between weight cycling and the risk of developing diabetes was not observed in obese participants (body mass index ≥30 kg/m2 ; P = 0.08). CONCLUSIONS The present meta-analysis showed that weight cycling was a strong independent predictor of new-onset diabetes. Future studies are required to detect the causal links between weight cycling and the risk of developing diabetes.

Differences in Kynurenine Metabolism During Depressive, Manic, and Euthymic Phases of Bipolar Affective Disorder. Curr Top Med Chem 2020; 20:1344-1352. [DOI: 10.2174/1568026619666190802145128] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2019] [Revised: 05/29/2019] [Accepted: 06/27/2019] [Indexed: 11/22/2022]
Abstract
Background & Objectives:
The kynurenine pathway is involved in inflammatory diseases. Alterations
of this pathway were shown in psychiatric entities as well. The aim of this study was to determine
whether specific changes in kynurenine metabolism are associated with current mood symptoms in bipolar
disorder.
Methods:
Sum scores of the Hamilton Depression Scale, Beck Depression Inventory, and Young Mania
Rating Scale were collected from 156 bipolar individuals to build groups of depressive, manic and
euthymic subjects according to predefined cut-off scores. Severity of current mood symptoms was correlated
with activities of the enzymes kynurenine 3-monooxygenase (ratio of 3-hydroxykynurenine/
kynurenine), kynurenine aminotransferase (ratio of kynurenic acid/ kynurenine) and kynureninase (ratio of
3-hydroxyanthranilic acid/ 3-hydroxykynurenine), proxied by ratios of serum concentrations.
Results:
Individuals with manic symptoms showed a shift towards higher kynurenine 3-monooxygenase
activity (χ2 = 7.14, Df = 2, p = .028), compared to euthymic as well as depressed individuals. There were no
differences between groups regarding activity of kynurenine aminotransferase and kynureninase. Within
the group of depressed patients, Hamilton Depression Scale and kynurenine aminotransferase showed a
significant negative correlation (r = -0.41, p = .036), displaying lower metabolism in the direction of
kynurenic acid.
Conclusion:
Depression severity in bipolar disorder seems to be associated with a decreased synthesis of
putative neuroprotective kynurenic acid. Furthermore, higher kynurenine 3-monooxygenase activity in currently
manic individuals indicates an increased inflammatory state within bipolar disorder with more severe
inflammation during manic episodes. The underlying pathophysiological mechanisms of the different affective
episodes could represent parallel mechanisms rather than opposed processes.

Abstract
Objectives: Bipolar disorder (BD) is often accompanied by medical comorbidities, which affect illness course and prognosis. Adipokines may not only be involved in the aetiopathogenetic mechanisms of these comorbidities; there might be an association between adipokines and the neuropsychiatric core features of BD such as mood disturbances and cognitive deficits.Methods: In this investigation, fasting blood samples from 120 individuals with BD (75 euthymic and 45 with mild depressive symptoms) and 68 control subjects were taken and adiponectin and leptin concentrations were analysed.Results: We found that, in female participants, adiponectin levels differed significantly between patients and controls indicating lower levels in individuals with BD, even after controlling for BMI (F(1,92) = 4.65, P = 0.034, partial η2 = 0.05). After stratification by mood status we found a significant difference in adiponectin between controls, euthymic and depressive patients (F(2, 180) = 4.90, P = 0.008, partial η2 = 0.05).Conclusions: This investigation confirms previous findings of an association between low adiponectin levels and depressive state in individuals with BD. Beyond its immediate effect on central nervous system function, adiponectin might interfere with pathophysiological mechanisms of BD and its somatic comorbidities via involvement in metabolic and inflammatory processes.

Abstract
OBJECTIVE Autistic traits are associated with a burdensome clinical presentation of anorexia nervosa (AN), as is AN with concurrent depression. The aim of the present study was to explore the intertwined association between complex psychopathology combining autistic traits, subthreshold bipolarity, and mixed depression among people with AN. METHOD Sixty patients with AN and concurrent major depressive episode (mean age, 22.2±7 years) were cross-sectionally assessed using the Autism-Spectrum Quotient test (AQ-test), the Hamilton depression scales for depression and anxiety, the Young Mania Rating Scale (YMRS), the Hypomania-Checklist-32 (HCL-32), second revision (for subthreshold bipolarity), the Brown Assessment and Beliefs Scale (BABS), the Yale-Brown-Cornell Eating Disorders Scale (YBC-EDS), and the Eating Disorder Examination Questionnaire (EDE-Q). Cases were split into two groups depending on body mass index (BMI): severe AN (AN+) if BMI < 16, not severe (AN-) if BMI ≥ 16. RESULTS The "subthreshold bipolarity with prominent autistic traits" pattern correctly classified 83.6% of AN patients (AN+ = 78.1%; AN- = 91.3%, Exp(B) = 1.391). AN+ cases showed higher rates of positive scores for YMRS items 2 (increased motor activity-energy) and 5 (irritability) compared to AN- cases. CONCLUSIONS In our sample, depressed patients with severe AN had more pronounced autistic traits and subtly mixed bipolarity. Further studies with larger samples and prospective follow-up of treatment outcomes are warranted to replicate these findings.

Abstract
Bipolar disorder (BPD) is a mood disorder, which is characterized by alternating affective states, namely (hypo)mania, depression, and euthymia. Evidence is growing that BPD has indeed a biologic substrate characterized by chronic inflammation, oxidative stress, and disturbed energy metabolism. Apart from this, there is obviously a hereditary component of this disease with multi-genetic factors. Most probably a susceptibility threshold favors the outbreak of clinical disease after a cascade of stress events that remain to be elucidated in more detail. Evidence is also growing that weak points in brain energy metabolism contribute to outbreak and severity of BPD. Conventional psychopharmacologic therapy must be reassessed under the aspects of weight cycling and development of central obesity as a deterioration factor for a worse clinical course leading to early cardiovascular events in BPD subgroups.

Abstract
Objective: We present novel dimensional methods to describe the timing of eating in psychopathology. We focused on the relationship between current mood in bipolar disorder (BD) and the stability of the temporal pattern of daily eating events. Methods: Consenting BD patients (n = 69) from an outpatient, tertiary care clinic completed hourly charts of mood and eating for two weeks. Mood was also evaluated with Montgomery-Åsberg Depression Rating Scale (MADRS) and Young Mania Rating Scale (YMRS). Results: Illustrative displays, or eatograms, enabling visualization of all recorded eating events were used to guide assessment of the temporal structure of eating across the two week assessment period. We computed indices to quantify irregularities in timing of eating, namely IFRQ, ITIM and IINT for the variability of frequency, timing, and interval of eating events, respectively. In this cohort, irregular temporal pattern of eating correlated with hypomanic symptoms (YMRS with IFRQ, Spearman rank order rh = 0.28, p = .019, with ITIM, rh = 0.44, p < .001, and with IINT rh = 0.38, p = .001), but not depressive symptoms or anthropometric measures. Conclusions: Our data suggest a link between the instability of the temporal order of daily eating and mood. The dimensional measures for eating pattern introduced here enable future investigations of correlations with psychopathology.

J Affect Disord 2018; 225:381-388. [PMID: 28846960 DOI: 10.1016/j.jad.2017.08.065] [Citation(s) in RCA: 37] [Impact Index Per Article: 6.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/09/2017] [Revised: 08/06/2017] [Accepted: 08/20/2017] [Indexed: 01/22/2023]
Abstract
BACKGROUND Albeit obesity and mood disorders frequently co-occur, few studies examined the impacts of this co-occurrence. The aim was to compare individuals with obesity and mood disorders (ObMD) to those with obesity without mood disorder in terms of physical comorbidities, psychological well-being, health behaviours and use of health services. METHODS Cross-sectional study using the Canadian Community Health Survey including a weighted sample of individuals with obesity (n = 1298) representing inhabitants from the province of Quebec (Canada). RESULTS Adjusted multivariate logistic regressions indicated that ObMD reported more physical conditions with odds ratio (OR) ranging from 1.8 [95%CI: 1.1 - 2.8] (hypertension) to 2.8 [95%CI: 1.3 - 6.0] (stomach ulcer). Also, ObMD reported poorer psychological well-being with OR ranging from 2.1 [95%CI: 1.4 - 3.3] (stress) to 25.6 [95%CI: 14.7 - 45.0] (poor perceived mental health). ObMD also reported more consultations with health professionals with OR ranging from 1.9 [95%CI: 1.0 - 3.5] (physicians) to 7.7 [95%CI: 4.2 - 14.3] (psychologists), and less healthy behaviours with OR ranging from 1.7 [95%CI: 1.1 - 2.6] (fruits and vegetables intake) to 2.1 [95%CI: 1.3 - 3.3] (tobacco). LIMITATIONS Self-reported data so we cannot discard the possibility of a bias in reporting. Also, given the cross-sectional design, no directional conclusion or causality about our results is possible. DISCUSSION The co-occurrence of mood disorder and obesity seems to be an aggravating factor of obesity-related factors because it is associated with poorer health in several areas. Interventions to prevent or manage obesity in mood disorders are necessary.

Abstract
OBJECTIVES New research is revealing a strong association between inflammatory markers with bipolar disorder (BD), potentially due to the high prevalence of cardiovascular disease and cardiovascular risk factors in BD. We aimed to synthesize the literature examining the association between the clinically most relevant inflammatory marker, C-reactive protein (CRP) and cardiovascular disease and cardiovascular risk factors in patients with BD. METHODS MEDLINE, Embase and PsychInfo were systematically searched for all relevant English language articles published prior to April 2017. Articles were included if they examined the association between CRP and cardiovascular risk factors/disease in BD. RESULTS Fifteen relevant articles were retrieved. Studies were mostly cross-sectional and heterogeneous in the cardiovascular risk factors investigated. Overall, elevated CRP was associated with increased risk of metabolic syndrome, elevated body mass index, higher waist circumference, and obesity. CRP was inconsistently associated with elevated fasting glucose, insulin levels, serum triglycerides, total cholesterol levels, and low high density lipoprotein (HDL) levels. Atypical antipsychotic use may mediate some of these effects. No study examined CRP's association with actual cardiovascular disease (e.g. coronary artery disease) in BD. CONCLUSIONS In BD, CRP is associated with increases in several cardiovascular risk factors, suggesting that systemic inflammation could be a shared driving force for both outcomes of BD and cardiovascular risk. Further longitudinal research is needed in this area to verify causality, including an examination of actual cardiovascular disease. Non-pharmacological and pharmacological treatments with anti-inflammatory effects should also be investigated, particularly in patients with increased CRP, for their potential to reduce cardiovascular risk in BD.

Abstract
INTRODUCTION It has been demonstrated that bipolar disorder (BD) is often accompanied by cognitive deficits across all subdomains including verbal memory, attention and executive functioning. Cognitive deficits are observed both during episodes of mania or depression, as well as during the euthymic phase. It has been proposed that chronic immune-mediated inflammation in the central nervous system results in alterations in neural structures that subserve cognitive function. Kynurenine is an intermediate in the inflammatory cascade and can be peripherally measured to proxy inflammatory activity. Herein, we sought to determine whether serum levels of kynurenine and/or its metabolites were associated with cognitive function in BD. METHODS In this investigation 68 euthymic individuals with BD according to DSM-IV completed a cognitive test battery to asses premorbid intelligence (Multiple Choice Word Test; MWT-B), verbal memory (California Verbal Learning Test; CVLT), attention (d2 Test of Attention; d2 test, Trail Making Test-A; TMT-A, Stroop word reading/Stroop color naming) and executive functioning (TMT-B, Stroop interference). In addition, fasting blood samples were taken and serum levels of kynurenine and its metabolites 3-hydroxykynurenine and kynurenic acid were analyzed. Subsequently ratios were formed from individual parameters. Patient data were compared with those of a mentally healthy control group (n=93). RESULTS In male participants with BD only we found a significant negative correlation between the 3-hydroxykynurenine to kynurenic acid ratio and performance on the CVLT. Additionally, the kynurenine to 3-hydroxykynurenine ratio was associated with performance on a sub-score of the CVLT. Those associations were neither present in female individuals with BD nor in the control group. DISCUSSION Our findings suggest that a shift towards the hydroxykynurenine arm of the kynurenine pathway may be associated with poorer memory performance due to its effects on neuronal functioning and neurogenesis in the hippocampus. Our results implicate a mechanistic role of central inflammatory processes in cognitive functions in adults with bipolar disorder.

Abstract
INTRODUCTION Bipolar disorder (BD) is a chronic psychiatric disease which can take most different and unpredictable courses. It is accompanied by unspecific brainstructural changes and cognitive decline. The neurobiological underpinnings of these processes are still unclear. Emerging evidence suggests that tryptophan catabolites (TRYCATs), which involve all metabolites of tryptophan towards the kynurenine (KYN) branch, are involved in the etiology as well as in the course of BD. They are proposed to be mediators of immune-inflammation and neurodegeneration. In this study we measured the levels of KYN and its main catabolites consisting of the neurotoxic hydroxykynurenine (3-HK), the more neuroprotective kynurenic acid (KYNA) and anthranilic acid (AA) and evaluated the ratios between end-products and substrates as proxies for the specific enzymatic activity (3-HK/KYN, KYNA/KYN, AA/KYN) as well as 3-HK/KYNA as a proxy for neurotoxic vs. neuroprotective end-product relation in individuals with BD compared to healthy controls (HC). METHODS We took peripheral TRYCAT blood levels of 143 euthymic to mild depressive BD patients and 101 HC. For statistical analyses MANCOVA's controlled for age, sex, body mass index, cardiovascular disease and smoking were performed. RESULTS The levels of KYNA (F = 5,579; p <.05) were reduced in BD compared to HC. The enzymatic activity of the kynurenine-3-monooxygenase (KMO) reflected by the 3-HK/KYN ratio was increased in BD individuals compared to HC (F = 5,394; p <.05). Additionally the ratio of 3-HK/KYNA was increased in individuals with BD compared to healthy controls (F = 11,357; p <.01). DISCUSSION In conclusion our findings subserve the concept of KYN -pathway alterations in the pathophysiology of BD. We present evidence of increased breakdown towards the neurotoxic branch in KYN metabolism even in a euthymic to mild depressive state in BD. From literature we know that depression and mania are accompanied by inflammatory states which should be capable to produce an even greater imbalance due to activation of key enzymes in the neurotoxic direction of KYN -conversion. These processes could finally be involved in the development of unspecific brain structural changes and cognitive deficits which are prevalent in BD. Further research should focus on state dependent changes in TRYCATs and its relation to cognition, brain structure and staging parameters.

Abstract
OBJECTIVES Overweight/obesity has been implicated to play a role in cognitive deficits in bipolar disorder (BD). This study aims to identify the relationship between body fat distribution and different domains of cognition in BD during euthymia. METHODS A sample of 100 euthymic individuals with BD was measured with a cognitive test battery (i.e., Trail Making Test-A-B/TM-A/B, d2 Test of Attention, Stroop test, California Verbal Learning Test/CVLT) and an anthropometric measures set (body mass index, waist circumference, hip circumference, waist-to-hip-ratio, waist-to-height-ratio, and lipometry). Patient data were compared with a healthy control group (n = 64). RESULTS Results show that overweight patients with BD exhibit lower performance in the TMT-A/B as well as in the free recall performance of the CVLT compared to normal-weight patients with BD and controls. In bipolar individuals, (abdominal) obesity was significantly associated with a poor cognitive performance. In bipolar females, associations with measures of verbal learning and memory were found; in bipolar males, associations with poor performance in the TMT-A/B and in the Stroop interference task were demonstrated. In controls, no associations were found. CONCLUSIONS There are several possible pathways moderating the association between obesity and cognition in BD. Anthropometric and lipometry data underline the substantial mediating impact of body fat distribution on cognition in BD.

Abstract
This study aimed to examine the role of oxidative stress in bipolar disorder (BD) by evaluating the relationship among antioxidant enzymes activities, impaired glucose metabolism (IGM) and illness course. We measured the activities of plasma superoxide dismutase (SOD) and glutathione peroxidase (GPx) in individuals with BD (N = 55) and healthy controls (N = 28). Information related to current and past psychiatric/medical history, as well as prescription of any pharmacological treatments was captured. Impaired glucose metabolism was operationalized as pre-diabetes or type 2 diabetes mellitus. Our results showed that, after adjustment for age, gender, alcohol use, smoking and current medication, both BD (p < 0.001) and IGM (p = 0.019) were associated with increased GPx activity, whereas only BD was associated with decreased SOD activity (p = 0.008). We also observed an interaction between BD and IGM on SOD activity (p = 0.017), whereas the difference between BD and controls was only significant in individuals with IGM (p = 0.009). IGM, GPx and SOD activity were independently associated with variables of illness course. Moreover, IGM moderated the association between SOD activity and number of mood episodes (p < 0.001), as a positive correlation between SOD activity and mood episodes was observed only in participants with IGM. In conclusion, BD and IGM are associated with independent and synergistic effects on markers of oxidative stress. The foregoing observations suggest that the heterogeneity observed in previous studies evaluating antioxidant enzymes in BD may be a function of concurrent IGM; and that imbalances in the oxidative system may subserve the association between BD and IGM, as well as its relationship with illness course.

Abstract
OBJECTIVES Matrix metallopeptidase 9 (MMP9) and soluble intercellular adhesion molecule 1 (sICAM-1) are both involved in the restructuring of connective tissues. Evidence also implicates MMP9 and sICAM in cardiovascular and neoplastic diseases, where blood levels may be a marker of disease severity or prognosis. In individuals with bipolar disorder (BD), higher risk for cardiovascular illness has been extensively reported. METHODS The aim of this investigation was to measure and compare peripheral levels of serum MMP9 and sICAM in adults with euthymic BD and healthy controls (HC). Furthermore, we focussed on correlations with illness severity and metabolic parameters. RESULTS MMP9 levels among the BD sample (n = 112) were significantly higher than among the HC (n = 80) (MMP9: F = 9.885, p = 0.002, η(2) = 0.058) after controlling for confounding factors. Patients with BD in a later, progressive stage of disease showed significantly higher MMP9 as well as sICAM-1 levels compared to patients with BD in an earlier stage of disease (MMP9: F = 5.8, p = 0.018, η(2) = 0.054; sICAM-1: F = 5.6, p = 0.020, η(2) = 0.052). Correlation analyses of cognitive measures revealed a negative association between performance on the d2 Test of Attention and MMP9 (r = -0.287, p = 0.018) in the BD sample. Despite the sample being euthymic (i.e., according to conventional criteria) at the time of analysis, we found significant correlations between MMP9 as well as sICAM-1 and subthreshold depressive/hypomanic symptoms. CONCLUSIONS A collection of disparate findings herein point to a role of MMP9 and cICAM-1 in the patho-progressive process of BD: the increased levels of serum MMP9 and sICAM-1, the correlation between higher levels of these parameters, progressive stage, and cognitive dysfunction in BD, and the positive correlation with subthreshold symptoms. As sICAM-1 and MMP9 are reliable biomarkers of inflammatory and early atherosclerotic disease, these markers may provide indications of the presence of occult cardiovascular disease in this highly at-risk population.

Abstract
OBJECTIVES It is well accepted that diet quality has an important role in the prevention and treatment of several physical diseases. However, its influence on mental health has received far less attention, although there is increasing evidence to support a relationship with depression. In this narrative review, investigations into the relationship between diet and bipolar disorder are examined and the potential implications in the management and treatment of bipolar disorder are reviewed. METHODS The authors provide a narrative review of the relevant information. RESULTS Research is limited, although there are preliminary findings to suggest a relationship between diet and bipolar disorder. Findings from cross-sectional research suggest that people with bipolar disorder consume an unhealthier dietary pattern. This has significant treatment implications as bipolar disorder has a high comorbidity with several physical diseases. In addition, diet also influences several biological processes that are dysregulated in bipolar disorder, namely monoaminergic activity, immune/inflammatory processes, oxidative stress, mitochondrial activity, and neuroprogression. CONCLUSIONS The role of diet in bipolar disorder requires further attention in research as it presents as a factor that may contribute to the worsening course of this condition and may potentially enhance current treatment outcomes.

Abstract
INTRODUCTION In the field of bipolar disorder (BD) research there is an absence of validated biomarkers and limited understanding of the biology underlying excessive and premature cardiovascular disease (CVD). Oxidative stress is a potential biomarker in both BD and CVD. OBJECTIVE To examine psychiatric and cardiovascular characteristics associated with peripheral oxidative stress markers among adolescents with BD, who are at high risk for CVD. METHODS Participants were 30 adolescents, 13-19years old, with BD and without CVD. Ultrasonography was used to evaluate vascular function and structure. Traditional CVD risk factors were also measured. Psychiatric assessments were conducted via semi-structured interview. Serum levels of oxidative stress (lipid hydroperoxides (LPH) and protein carbonylation (PC)) were assayed. RESULTS Compared to published data on adults with BD, adolescents had significantly lower levels of LPH and PC (t52(11.34), p<0.0001; t58(29.68), p<0.0001, respectively). Thicker mean and maximum carotid intima media thickness was associated with greater levels of LPH (r=.455, p=.015; r=.620, p<0.0001, respectively). LPH was associated with diastolic blood pressure (r=-.488, p=0.008) and pulse pressure (r=.543, p=0.003). Mood symptoms and medication were not significantly associated with oxidative stress. CONCLUSION Adolescents with BD have lower levels of oxidative stress compared to adults with BD, supporting prevailing illness staging theories for BD. Oxidative stress is robustly associated with a proxy measure of atherosclerosis and may explain in part the increased risk of CVD in BD.

Cerebral White Matter Lesions and Affective Episodes Correlate in Male Individuals with Bipolar Disorder. PLoS One 2015; 10:e0135313. [PMID: 26252714 PMCID: PMC4529150 DOI: 10.1371/journal.pone.0135313] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2015] [Accepted: 07/20/2015] [Indexed: 12/21/2022] Open
Abstract
Background Cerebral white matter lesions (WML) have been found in normal aging, vascular disease and several neuropsychiatric conditions. Correlations of WML with clinical parameters in BD have been described, but not with the number of affective episodes, illness duration, age of onset and Body Mass Index in a well characterized group of euthymic bipolar adults. Herein, we aimed to evaluate the associations between bipolar course of illness parameters and WML measured with volumetric analysis. Methods In a cross-sectional study 100 euthymic individuals with BD as well as 54 healthy controls (HC) were enrolled to undergo brain magnetic resonance imaging using 3T including a FLAIR sequence for volumetric assessment of WML-load using FSL-software. Additionally, clinical characteristics and psychometric measures including Structured Clinical Interview according to DSM-IV, Hamilton-Depression, Young Mania Rating Scale and Beck’s Depression Inventory were evaluated. Results Individuals with BD had significantly more (F = 3.968, p < .05) WML (Mdn = 3710mm3; IQR = 2961mm3) than HC (Mdn = 2185mm3; IQR = 1665mm3). BD men (Mdn = 4095mm3; IQR = 3295mm3) and BD women (Mdn = 3032mm3; IQR = 2816mm3) did not significantly differ as to the WML-load or the number and type of risk factors for WML. However, in men only, the number of manic/hypomanic episodes (r = 0.72; p < .001) as well as depressive episodes (r = 0.51; p < .001) correlated positively with WML-load. Conclusions WML-load strongly correlated with the number of manic episodes in male BD patients, suggesting that men might be more vulnerable to mania in the context of cerebral white matter changes.
