Individual Burden of Illness Index in Bipolar Disorder Remission: A Cross-Sectional Study

BACKGROUND: A population-based method for estimating disease burden is commonly used. Nevertheless, these measurements do not entirely capture the comprehensive burden of illness on an individual patient. To address the problem, the Individual Burden of Illness Index (IBI index) Index was created and validated, specifically for major depressive disorder. The IBI represents the overall influence of the condition, encompassing distress from symptom intensity, functional impairment, and the patient’s quality of life. AIM: The aim of the study was to approve and validate the IBI index for the integral assessment of disease burden in patients with bipolar disorder (BD) in remission. METHODS: The cross-sectional study was conducted in the outpatient psychiatric services in Saint Petersburg, Russia, from April through October 2020. Eighty-five patients aged 18 to 45 (mean age 36.6±5.7 years) with BD (type I — 75%, n=64; type II — 25%, n=21) in remission were examined. The study procedure included a structured clinical interview and the use of clinical scales: the World Health Organization’s Quality of Life Questionnaire, Hamilton Rating Scale for Depression (HDRS), Young Mania Rating Scale (YMRS), and Personal and the Social Performance Scale. RESULTS: The principal component analysis in accordance with the adjusted one showed that the burden of illness in patients with BD in remission is directly related to the severity of residual depressive symptoms, reflected in the HDRS score: as the HDRS score increases (0.27, p 0.001), residual mania (-0.14, p 0.001), social functioning (-0.06, p 0.001), and quality of life (-0.04, p 0.001) decrease. In contrast, when there are remaining residual mania symptoms, as indicated by the YMRS score, the result tends to be a lower burden, better social functioning, and enhanced quality of life. CONCLUSION: The study has demonstrated through statistical means a successful adaptation and validation of the previously calculated IBI index for patients with BD in remission. Residual affective symptoms were shown to have different impacts on the social functioning of patients with BD in remission, indicating the need for a timely assessment and targeted therapy of these symptoms in such patients.

Integrated proteomic and genomic analysis to identify predictive biomarkers for valproate response in bipolar disorder: a 6-month follow-up study

BackgroundSeveral genetic studies have been undertaken to elucidate the intricate interplay between genetics and drug responses in bipolar disorder (BD). However, there has been notably limited research on biomarkers specifically linked to valproate, with only a few studies investigating integrated proteomic and genomic factors in response to valproate treatment. Therefore, this study aimed to identify biological markers for the therapeutic response to valproate treatment in BD. Patients with BD in remission were assessed only at baseline, whereas those experiencing acute mood episodes were evaluated at three points (baseline, 8 ± 2 weeks, and 6 ± 1 months). The response to valproate treatment was measured using the Alda scale, with individuals scoring an Alda A score ≥ 5 categorized into the acute-valproate responder (acute-VPAR) group. We analyzed 158 peptides (92 proteins) from peripheral blood samples using multiple reaction monitoring mass spectrometry, and proteomic result-guided candidate gene association analyses, with 1,627 single nucleotide variants (SNVs), were performed using the Korean chip.ResultsThe markers of 37 peptides (27 protein) showed temporal upregulation, indicating possible association with response to valproate treatment. A total of 58 SNVs in 22 genes and 37 SNVs in 16 genes showed nominally significant associations with the Alda A continuous score and the acute-VPAR group, respectively. No SNVs reached the genome-wide significance threshold; however, three SNVs (rs115788299, rs11563197, and rs117669164) in the secreted phosphoprotein 2 gene reached a gene-based false discovery rate-corrected significance threshold with response to valproate treatment. Significant markers were associated with the pathophysiological processes of bipolar disorders, including the immune response, acute phase reaction, and coagulation cascade. These results suggest that valproate effectively suppresses mechanisms associated with disease progression.ConclusionsThe markers identified in this study could be valuable indicators of the underlying mechanisms associated with response to valproate treatment.

APOE Genotype, ApoE Plasma Levels, Lipid Metabolism, and Cognition in Monozygotic Twins with, at Risk of, and without Affective Disorders.

Background: Lipids influence brain function and mental health. Understanding the role of apolipoproteins in affective disorders could provide valuable insights and potentially pave the way for novel therapeutic approaches. Methods: We examined the apolipoprotein E genotype and ApoE-levels, lipid profiles, and the correlation with cognition in 204 monozygotic (MZ) twins with unipolar or bipolar disorder in remission or partial remission (affected, AT), their unaffected co-twins (high-risk, HR), and twins with no personal or family history of affective disorder (low-risk, LR). Results: The APOE genotype was not associated with affective disorders. No significant group differences in ApoE levels were found between the three risk groups. Post hoc analysis group-wise comparisons showed higher ApoE levels in the AT than HR twins and in the concordant AT twin pairs relative to the discordant twin pairs. Within the discordant twin pairs, higher ApoE levels were observed in the affected twins (AT = 39.4 mg/L vs. HR = 36.8 mg/L, p = 0.037). Limitations: The present study could benefit from a larger sample size. We did not assess dietary habits. Conclusions: The results did not support our main hypothesis. However, exploratory post hoc analysis suggests a role for plasma ApoE and triglycerides in affective disorders. Future research is needed.

Aerobic capacity and mitochondrial function in bipolar disorder: a longitudinal study during acute phases and after clinical remission.

Aerobic capacity has shown to predict physical and mental health-related quality of life in bipolar disorder (BD). However, the correlation between exercise respiratory capacity and mitochondrial function remains understudied. We aimed to assess longitudinally intra-individual differences in these factors during mood episodes and remission in BD. This study included eight BD patients admitted to an acute psychiatric unit. Incremental cardiopulmonary exercise test (CPET) was conducted during acute episodes (T0), followed by constant work rate cycle ergometry (CWRCE) to evaluate endurance time, oxygen uptake at peak exercise (VO2peak) and at the anaerobic threshold. The second test was repeated during remission (T1). Mitochondrial respiration rates were assessed at T0 and T1 in peripheral blood mononuclear cells. Endurance time, VO2peak, and anaerobic threshold oxygen consumption showed no significant variations between T0 and T1. Basal oxygen consumption at T1 tended to inversely correlate with maximal mitochondrial respiratory capacity (r=-0.690, p=0.058), and VO2peak during exercise at T1 inversely correlated with basal and minimum mitochondrial respiration (r=-0.810, p=0.015; r=-0.786, p=0.021, respectively). Our preliminary data showed that lower basal oxygen consumption may be linked to greater mitochondrial respiratory capacity, and maximum oxygen uptake during the exercise task was associated with lower basal mitochondrial respiration, suggesting that lower oxygen requirements could be associated with greater mitochondrial capacity. These findings should be replicated in larger samples stratified for manic and depressive states.

Associations of altered leukocyte DDR1 promoter methylation and childhood trauma with bipolar disorder and suicidal behavior in euthymic patients.

Altered DNA methylation (DNAm) patterns of discoidin domain receptor 1 (DDR1) have been found in the blood and brain of patients with schizophrenia (SCZ) and the brain of patients with bipolar disorder (BD). Childhood trauma (CT) is associated with changes in DNAm that in turn are related to suicidal behavior (SB) in patients with several psychiatric disorders. Here, using MassARRAY® technology, we studied 128 patients diagnosed with BD in remission and 141 healthy controls (HCs) to compare leukocyte DDR1 promoter DNAm patterns between patients and HCs and between patients with and without SB. Additionally, we investigated whether CT was associated with DDR1 DNAm and mediated SB. We found hypermethylation at DDR1 cg19215110 and cg23953820 sites and hypomethylation at cg14279856 and cg03270204 sites in patients with BD compared to HCs. Logistic regression models showed that hypermethylation of DDR1 cg23953820 but not cg19215110 and CT were risk factors for BD, while cg14279856 and cg03270204 hypomethylation were protective factors. In patients, CT was a risk factor for SB, but DDR1 DNAm, although associated with CT, did not mediate the association of CT with SB. This is the first study demonstrating altered leukocyte DDR1 promoter DNAm in euthymic patients with BD. We conclude that altered DDR1 DNAm may be related to immune and inflammatory mechanisms and could be a potential blood biomarker for the diagnosis and stratification of psychiatric patients.

Thiol-disulphide homeostasis, ischemia-modified albumin, complete blood count-derived inflammatory markers and C-reactive protein from acute mania to early remission in bipolar disorder

ObjectivesThere is much recent evidence that inflammation contributes to the pathophysiology of acute mania in bipolar disorder (BD). However, no study was evaluated in which the change in thiol-disulphide homeostasis, ischemia-modified albumin (IMA), complete blood count-derived inflammatory markers (CBC-IMs) and C-reactive protein (CRP) levels in bipolar patients was followed-up from acute mania to early remission. MethodsSeventy-seven bipolar patients in acute mania and ninety-one HC were enrolled. We measured levels of thiol-disulphide parameters, IMA, and CBC-IMs such as neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), red-cell-distribution-width (RDW)-to-platelet ratio (RPR), systemic immune-inflammatory index (SII), and systemic inflammatory response index (SIRI), CRP and platelet-to-albumin ratio (PAR), after adjusting for age, gender, body-mass index (BMI) and smoking status, during acute mania to subsequent early remission. The results were compared with HC. ResultsThe levels or ratios of all thiol-disulphide parameters except for disulphide, IMA and CRP of bipolar patients in both acute mania and early remission were significantly different from HC, after adjusting for confounders. The NLR, SII, CRP and PAR values of bipolar patients were significantly higher in only acute mania compared to HC. Significant changes in thiol-disulphide parameters and IMA levels were not found in early remission after acute mania. LimitationsShort follow-up period and lack of drug-naive patients. ConclusionsOur results suggest that thiol-disulphide parameters, IMA level and SIRI value might be a trait biomarkers of inflammation in BD. In addition, NLR, SII and PAR values and CRP level might be a state biomarker of inflammation in bipolar patients in a manic phase.

The Relationship between Functioning Levels and Exercise Addiction, Personality, and Temperament Characteristics in Patients with Bipolar Disorder during Remission Period

Objective: Bipolar disorder (BD) progresses in episodes and includes periods of remission between episodes. Although symptoms are decreased during remission, patients' functioning levels may be lower than the pre-disease period. This study aims to evaluate the relationship between the level of functioning and exercise addiction, temperament and personality traits in patients with BD in remission. Methods:In this study, BD patients who have been in remission for three months and more were evaluated. Young Mani Rating Scale and Hamilton Depression Rating Scale were used to determine the status of remission. Bipolar Disorder Functioning Scale was used for functioning, Eysenck Personality Survey-Revised Short Form for personality, TEMPS-A temperament scale for temperament, and the Exercise Addiction Scale was used for exercise addiction. Results:92 BD patients in remission were included in the study. A positive relationship was found between functioning level and hyperthymic temperament and extraversion, and a negative relationship was found between depressive temperament, cyclothymic temperament, irritable temperament, anxious temperament, neuroticism, and psychoticism. Although these patients had a certain degree of exercise dependence, it did not have a relationship with functioning. Conclusion: Functionality may be affected by personality and temperament characteristics during remission periods in BD. Psychosocial interventions in these areas may be beneficial in the treatment of these patients.

Decreased Psychological Well-Being in Patients With Bipolar Disorder in Remission.

The goals of this study were to introduce psychological well-being as an important subject of inquiry in bipolar disorder, to compare well-being in a cohort of patients with bipolar disorder with that of a normative sample, and to assess whether common measures of well-being and mood measure empirically distinct phenomena. Participants were outpatients with bipolar I disorder in remission (N=37) from the Enhancing Emotion Regulation in Bipolar Disorder (EERBD) study and a matched community normative sample from the Midlife in the United States (MIDUS) survey (N=6297). The Psychological Well-Being Scale (PWBS) was used to measure psychological well-being. We calculated means and SD of scores on the PWBS and evaluated the differences between the scores of the bipolar I and community samples. We also tested the association between raw and change scores in depression [Hamilton Rating Scale for Depression (HAM-D)] and eudaimonic well-being (PWBS) using Spearman correlation coefficients. The MIDUS survey sample (N=6297) was 48% male, with a mean age of 47 years (SD=13y). The EERBD sample (N=37) was 27% male, with a mean age of 41 years (SD=11y). In the bipolar sample, the baseline mean score on the HAM-D was 12.7 (SD=6.0) and the mean score on the Young Mania Rating Scale was 6.1 (SD=6.2). The baseline mean sum score on the PWBS in the normative community MIDUS sample was 100 (SD=14), while that of the bipolar I EERBD sample was 79 (SD=15) at baseline, 84 (SD=13) posttreatment, and 84 (SD=12) at the 3-month follow-up assessment. The effect sizes of the differences at all timepoints were large (Hedges g=1.42 at baseline, 1.11 at the end of treatment, and 1.06 at the 3-mo follow-up). No association was found between the PWBS and depression scores. Outpatients with bipolar disorder in remission demonstrated substantially impaired psychological well-being, despite low levels of depressive symptoms, compared with a normative community sample.

Association of current and remitted bipolar disorders with health-related quality of life: Findings from a nationally representative sample in the US

BackgroundThe associations of current and remitted bipolar disorder (BD) with health-related quality of life (HRQOL) have been under-studied, and we aim to address these gaps. MethodsThe 2012–2013 National Epidemiological Survey on Alcohol and Related Conditions III (NESARC III) surveyed a nationally representative sample of non-institutionalized adults in the US. Using DSM-5 criteria, three groups were operationalized as: 1) adults who met criteria for BD in the past year (i.e., current BD; n = 566 unweighted); and 2) adults who met criteria for BD previously but not in the past year (i.e., BD in remission; n = 187); and 3) adults with no BD in their lifetime (n = 35,556). HRQOL and quality-adjusted life years (QALYs) were compared by these groups. Multivariable-adjusted regression analyses were used to adjust for and examine the role of covariates. ResultsOverall, 1.5 % of the study sample, representing 3.6 million adults nationwide, met criteria for current BD, and 0.5 %, representing 1.3 million adults, met criteria for BD in remission. Adults with current BD and BD in remission had lower mental HRQOL and QALYs, as compared to adults who never had BD. However, these differences were no longer significant when adjusted for behavioral co-morbidities (e.g., psychiatric and substance use disorders). ConclusionBoth current BD and BD in remission were adversely associated with HRQOL and QALYs, while these associations were not independent of behavioral co-morbidities. Because behavioral co-morbidities are common in individuals with current BD or those with BD in remission, they should be treated together to improve HRQOL.

Distinguishing major depressive disorder from bipolar disorder in remission: A brain structural network analysis

BackgroundIt is challenging to differentiate major depressive disorder (MDD) from bipolar disorder (BD) in depression and remission. To exclude the potential influence of depressive episodes, we compared the white matter (WM) network between MDD and BD patients in remission to find disease-specific alterations in MDD and BD, and then distinguish these two affective disorders. MethodsWe recruited 33 patients with remitted MDD (rMDD), 54 patients with remitted BD (rBD), and 60 healthy controls (HCs). Diffusion tensor imaging and high-resolution 3D T1-weighted image were acquired. Global and nodal topological parameters were used to depict the alterations of the whole-brain WM network. ResultsWe found that rMDD displayed increased global network efficiency (Eglob) and local network efficiency (Eloc) compared with HCs, whereas we found no significance between rBD and HCs. Compared with rBD and HCs, patients in the rMDD group showed increased nodal degree and nodal efficiency, and decreased nodal shortest path length in the four cerebral regions, including the right calcarine fissure (CAL.R), right cuneus (CUN.R), left lingual gyrus (LING.L), and left middle occipital gyrus (MOG.L). We did not find any rBD specific changes of nodal topological metrics. LimitationsThe main limitation is the possible effects of medication and BD subtypes on the results. ConclusionsOur findings indicate that rMDD exhibited elevated global properties compared with HCs group, and increased nodal properties in the CAL.R, CUN.R, LING.L, and MOG.L specifically compared with rBD and HCs, which may underlie the distinction of the two affective disorders in remission.

Theory of Mind Deficits in Bipolar Disorder in Remission

AimsTheory of mind (ToM) is the ability to represent one's own and other's mental state. Studies in bipolar affective disorder show mixed results possible due to confounding factors like intelligence, attention, phase of illness and current mood. Purpose of this study is to study ToM in remittent bipolar disorder patients and compare with normal controls to find if there are residual deficits during remissionMethods40 bipolar patients in remission and 40 age and sex matched controls were recruited. Clinical remission for 3 months with YMRS <4 and HAM-D <7 was inclusion criteria. ToM was assessed by Faux Pas test. Data were analysed using SPSS-11.5 for Windows with parametric and non-parametric tests as indicated. Level of significance taken as p < 0.05 (two tailed).ResultsMean age of onset of illness in patient group was 23.8 years with duration of illness 11.3 years. Mean number of episodes 6.7 and duration of remission 4.15 months. ToM test result revealed deficit in recognizing social cues in faux pas test by bipolar patients as compared to normal controls. There was no difference between both groups in test result on control stories.ConclusionResults suggest that ToM deficits are present in bipolar disorder patients even during apparent clinical remission, indicating it may be a trait marker of the illness. There is no deficit in understanding a regular social context without faux pas. It also revealed that there is no correlation with ToM and duration of illness

Mother-Infant Bonding in Patients with Bipolar Disorder.

The quality of mother-infant bonding might play a role in future psychopathologies of the infant. The present study aims to compare the mother-infant bonding in mothers with remitted bipolar disorder (BD) and healthy mothers. We included 51 mothers who have bipolar disorder in remission and 53 healthy mothers during postpartum one-year period. All participants were interviewed with Structured Clinical Interview for DSM-IV (SCID-IV). Young Mania Rating Scale and the Hamilton Depression Rating Scale were given to the patient group to evaluate depressive and manic symptoms. Mother-infant bonding in both groups were evaluated with the Postpartum Bonding Questionnaire (PBQ). There was no significant difference in PBQ scores between the bipolar group and the control group. Age was negatively correlated with PBQ scores in the patient group. Women with bipolar disorder can develop healthy bonding patterns with their babies, during remission.

Beneficial effect of lithium in female patient with bipolar affective illness and psoriasis

Objectives. Psoriasis makes a relative contraindication for lithium treatment which can exacerbate its symptoms or induce it itself. On the other hand, lithium exerts immuno-modulatory activity. Case study. In this paper, a case of a female patient is presented. The patient has been treated since 2012 for bipolar affective illness (bipolar disorder – BD) and psori­asis, which occurred for the first time during a depress­ive episode. Despite intensive pharmacological treatment, both as inpatient and outpatient, a satisfactory improvement of affective illness has not been obtained. After the introduction of lithium, a remission of BD was achieved as well as a reduction of psoriatic changes, which have been maintained until now (2021). Conclusion. The remission of Bipolar Disorder (BD) on lithium can suggest that the patient belongs to the group of the so-called excellent lithium responders. In the presen­ted case remission of psoriasis was observed during lithium treatment. This case report must be treated with caution because remission could be spontaneous and the patient needs further observation.

Reduced prefrontal cortex response to own vs. unknown emotional infant faces in mothers with bipolar disorder

Motherhood involves functional brain adaptations within a broad neural network purported to underlie sensitive caregiving behavior. Bipolar disorder (BD) is associated with aberrant brain response to emotional faces within a similar network, which may influence BD mothers’ sensitivity to infant faces. This functional magnetic resonance imaging (fMRI) study aimed to investigate whether mothers with BD display aberrant neural responses to own infant faces compared to healthy mothers. Twenty-six mothers with BD in remission and 35 healthy mothers underwent fMRI during which they viewed happy and distressed still facial photographs of their own and of unknown infants. After the scan, mothers viewed the pictures again on a computer screen and rated the intensity of infants’ facial emotions and their own emotional response to infant face images. Mothers with BD displayed lower left dorsolateral prefrontal cortex (dlPFC) response compared to healthy mothers to own vs. unknown infant faces specifically and abnormal positive functional connectivity between the left and right amygdala and prefrontal regions. BD mothers further displayed stronger deactivation of precuneus and occipital regions to all happy vs. distressed infant faces. After the scan, they rated their infants’ distress and own response to their infants’ distressed faces less negatively than healthy mothers. Blunted dlPFC response and aberrant fronto-limbic connectivity while viewing own infant faces and less negative ratings of own infants’ distress in BD mothers may affect their responses to their own infants in real-life mother-infant interactions.

Validation of the youth mood recurrences risk calculator in an adult sample with bipolar disorder

BackgroundThe ability to predict an individual's risk of mood episode recurrence can facilitate personalized medicine in bipolar disorder (BD). We sought to externally validate, in an adult sample, a risk calculator of mood episode recurrence developed in youth/young adults with BD from the Course and Outcome of Bipolar Youth (COBY) study. MethodsAdult participants from the National Institute of Mental Health Collaborative Depression Study (CDS; N=258; mean(SD) age=35.5(12.0) years; mean follow-up=24.9 years) were utilized as a sample to validate the youth COBY risk calculator for onset of depressive, manic, or any mood episodes. ResultsIn this older validation sample, the risk calculator predicted recurrence of any episode over 1, 2, 3, or 5-year follow-up intervals, with Area Under the Curves (AUCs) approximating 0.77. The AUC for prediction of depressive episodes was about 0.81 for each of the time windows, which was higher than for manic or hypomanic episodes (AUC=0.72). While the risk calculator was well-calibrated across the range of risk scores, it systematically underestimated risk in the CDS sample by about 20%. The length of current remission was a highly significant predictor of recurrence risk in the CDS sample. LimitationsPredominantly self-reported White samples may limit generalizability; the risk calculator does not assess more proximal risk (e.g., 1 month). ConclusionsRisk of mood episode recurrence can be predicted with good accuracy in youth and adults with BD in remission. The risk calculators may help identify higher risk BD subgroups for treatment and research.

Emotion Processing Deficit in Euthymic Bipolar Disorder: A Potential Endophenotype.

Background:Emotion processing deficits have been described in patients with bipolar disorder (BD) and are considered one of the core cognitive abnormalities in BD with endophenotype potential. However, the literature on specific impairments in emotion processing cognitive strategies (directive/cortical/higher versus intuitive/limbic/lower) in euthymic adult BD patients and healthy first-degree relatives/high-risk (HR) subjects in comparison with healthy controls (HCs) is sparse.Methods:We examined facial emotion recognition deficits (FERD) in BD (N = 30), HR (N = 21), and HC (N = 30) matched for age (years), years of education, and sex using computer-administered face emotions–Matching And Labeling Task (eMALT).Results:The three groups were significantly different based on labeling accuracy scores for fear and anger (FA) (P < 0.001) and sad and disgust (SD) (P < 0.001). On post-hoc analysis, HR subjects exhibited a significant deficit in the labeling accuracy of FA facial emotions (P < 0.001) compared to HC. The BD group was found to have significant differences in all FA (P = 0.004) and SD (P = 0.003) emotion matching as well as FA (P = 0.001) and SD (P < 0.001) emotion labeling accuracy scores.Conclusions:BD in remission exhibits FERD in general, whereas specific labeling deficits of fear and anger emotions, indicating impaired directive higher order aspect of emotion processing, were demonstrated in HR subjects. This appears to be a potential endophenotype. These deficits could underlie the pathogenesis in BD, with possible frontolimbic circuitry impairment. They may have potential implications in functional recovery and prognosis of BD.

Personality dimensions and coping strategies in remitted bipolar disorder

IntroductionThe influence of personality on how people deal with stressful situations has long been discussed. In bipolar disorder, these two entities seem to have a role in the outcome of the disease.ObjectivesTo study the relationships between coping strategies in stressful situations and personality dimensions in euthymic bipolar patients.MethodsThis is a cross-sectional, descriptive and analytical study of 30 patients followed for bipolar disorder in remission, at the psychiatric outpatient clinic at the Hédi Chaker Uuniversity Hospital in Sfax. We used a socio-demographic and clinical data sheet and the Ten Items Personality Inventory (TIPI) to evaluate personality dimensions and the Ways Of Coping Checklist (WWC) for the assessment of coping.ResultsThe mean age of the patients was 43.77 years, the sex ratio was 0.5. Bipolar I disorder was diagnosed in 93% of patients. WCC : -Coping focused on the problem : 70% of the patients. -Emotion-centered coping : 20% of patients -Coping focused on seeking social support : 10% of patients. TIPI : Conciousness was the most represented trait of personality (36.7%), agreableness (30%) and extraversion (20%). Extraversion was associated with coping focused on the problem: (p=0.015). Agreableness was associated with coping focused on seeking social support:(p=0.033).ConclusionsOur study showed that conciousness is the most common trait of personality in bipolar disorder patients. The coping focused on the problem is the most frequent strategy which correlated with extraversion, so, personality dimensions appear as a target for cognitive interventions.DisclosureNo significant relationships.

Emotion regulation in euthymic bipolar patients in Tunisia

IntroductionBipolar disorder is presumed to involve difficulties in emotion regulation. However, little is known about the specific emotion regulation profile associated with this disorder.ObjectivesTo study emotion regulation in bipolar patients in remission phase and to determine the factors correlated with it.MethodsA cross-sectional, descriptive and analytical study of 30 patients followed for bipolar disorder in remission, at the psychiatric outpatient clinic at the Hédi Chaker University Hospital in Sfax. We used a socio-demographic and clinical data sheet and the Cognitive Emotion Regulation Questionnaire (CERQ) which assesses cognitive strategies (maladaptive and adaptive) for regulating emotion.ResultsThe mean age of the patients was 43.77 years, the sex ratio was 0.5. Bipolar I disorder was diagnosed in 93% of patients. A good adherence to treatment was found in 86.7% of cases and a good social integration in 40%. The mean total score of the adaptive CERQ was 66.73 and the most used adaptive strategy was acceptation (mean score =13.87), while the mean total score of the maladaptive CERQ was 36.7 and the most used maladaptive strategy was self blame (mean score =9.47). Adaptive cognitive emotion regulation was predominant in 93.3% of patients. It was significantly correlated with good adherence to treatment (p = 0.047) and good social integration (p = 0.026).ConclusionsOur patients with euthymic bipolar disorder showed a satisfying level of adaptive emotion regulation strategies. A cognitive remediation seems important to embetter this capacity and improve the income of the disease.DisclosureNo significant relationships.

Change in prefrontal activity and executive functions after action-based cognitive remediation in bipolar disorder: a randomized controlled trial.

Cognitive impairment is prevalent in bipolar disorder (BD) but treatments with pro-cognitive effects are lacking. Insight concerning the neurocircuitry of cognitive improvement could provide a biomarker for pro-cognitive effects to advance treatment development. The dorsal prefrontal cortex (dPFC) is a promising region for such treatment target engagement. The aim of this functional magnetic resonance imaging (fMRI) study was to examine the effects of action-based cognitive remediation (ABCR) on early change in the dPFC blood-oxygen-level-dependent response in patients with BD in remission, and whether the observed neural change predicted improved executive functions following 10 weeks of treatment. Forty-five participants with remitted BD (ABCR: n = 26, control treatment: n = 19) completed a spatial n-back working memory task during fMRI and executive function tasks outside the scanner before and after two weeks of ABCR/control treatment, and an additional assessment of executive function at treatment completion. Thirty-four healthy controls underwent a single fMRI and executive function assessment for baseline comparisons. We found an early reversal of pretreatment hypo-activity in the dorsolateral prefrontal cortex (dlPFC) following ABCR vs. control during both high-load (2-back > 1-back) working memory (WM) (F(1,43) = 5.69, p = 0.02, η2 = 0.12) and general WM (2-back > 0-back) (F(1,43) = 5.61, p = 0.02, η2 = 0.12). This dlPFC activity increase predicted improved executive functions at treatment completion (high-load WM: B = -0.45, p = 0.01, general WM: B = -0.41, p < 0.01), independent of changes in subsyndromal symptoms. In conclusion, early dPFC increase may provide a neurocircuitry-based biomarker for pro-cognitive effects. Future cognition trials should include fMRI assessments to confirm the validity of this putative biomarker model across disorders with cognitive impairment.

High-Sensitive c-Reactive Protein Levels in Euthymic Bipolar Patients: Case-Control Study.

Bipolar disorder is a chronic, disabling disease that is characterized by the recurrence of thymic episodes. The role of the immune-inflammatory system in the etiopathogenesis of this affection arouses the interest of research. The aim of this work was to determine the plasma levels of the high sensitivity C reactive protein (hs-CRP) in patients with bipolar disorder in remission phase by comparing them to a control group.A case-control cross-sectional study was conducted from 56 subjects with bipolar disorder in clinical remission, and 56 volunteers and healthy control subjects.Mean plasma hs-CRP was significantly higher in patients with bipolar disorder than control subjects. In bipolar patients, a hs-CRP elevation was significantly associated with the disease severity item mean score.Through this study, bipolar disorder appears to be associated with a state of chronic inflammation. This should lead to randomized controlled trials evaluating the value of anti-inflammatory drugs in the management of bipolar disorder.
