Damage accrual, cumulative glucocorticoid dose and depression predict anxiety in patients with systemic lupus erythematosus

Undiagnosed Depression and Its Effects on Patients With Systemic Lupus Erythematosus

Introduction Different organs and organ systems are affected by a well-known chronic immune disorder called systemic lupus erythematosus (SLE). Besides the physical harm caused by this disorder, it affects the mental health of patients in a greater ratio by causing depression and anxiety. The objective of this study is to assess the prevalence of undiagnosed depression and its effects on patients with systemic lupus erythematosus. Material and methods This prospective cross-sectional study was carried out in the Rheumatology outpatient department of Fatima Memorial Hospital (FMH), Lahore, from November 2022 to February 2023. All study subjects had been given a prior diagnosis of SLE based on the 2012 Systemic Lupus International Collaborating Clinics (SLICC) criteria. Three sections comprised the survey form: section I asked questions about socio-demographic information (gender and age); section II assessed the degree of mental illness activity; and section III assessed the degree of SLE disease activity. The nine-item PHQ-9 (Patient Health Questionnaire 9) scale, which is used to diagnose severe depressive disorder, was utilized to measure depression. To compare categorical variables, we applied Fisher's exact tests and chi-square; for continuous variables, we utilized the student's t-test. The statistical analysis was conducted using SPSS software for Windows Version 21.0 (IBM Corp., Armonk, NY, USA), with a significance threshold of p-value <0.05. Results Mild, moderate, and severe depression were present in 20%, 37.5%, and 37.5% of the patients, respectively. Pearson correlation of disease severity was strongly positive with depression (R2=0.634, p=0.01). The correlation was statistically significant. Conclusion Our research indicates that depression is a real problem for SLE patients. There is a positive correlation between the activity of the disease and the intensity of depression.

Effects of illness perception on negative emotions and fatigue in chronic rheumatic diseases: Rumination as a possible mediator

BACKGROUND

Illness perception has long been hypothesized to be linked to psychological well-b eing in patients with rheumatic diseases, although substantial evidence is lacking, and the contribution of ruminative coping style to this relationship is unclear.

AIM

To investigate the roles of illness perception and rumination in predicting fatigue and negative emotions in patients with chronic rheumatic diseases.

METHODS

Illness perception, rumination, fatigue and negative emotions (i.e. depression, anxiety and stress) were assessed by the Illness Perception Questionnaire-Revised, Stress Reactive Rumination Scale, Multidimensional Assessment of Fatigue, and the Depression, Anxiety and Stress Scale respectively. Multivariate regression analysis, the Sobel test, and the bootstrap were used to identify the mediating effect of rumination.

RESULTS

All five subscales of illness perception, including perceived illness identity, chronicity, cyclical nature, consequences and coherence of illness, were significantly associated with fatigue and negative emotions. In mediational analysis, rumination was found to mediate three components of illness perception (the identity, cyclical nature and consequences of illness) and negative emotions/fatigue.

CONCLUSION

Perceived identity, cyclical nature, and consequences of illness are significantly associated with fatigue and negative emotions in patients with chronic rheumatic diseases and these associations are mediated by rumination. Our findings suggest that psychological intervention should target rumination to improve physical and emotional well-being of patients with chronic rheumatic diseases.

A cross-sectional study on the association of anxiety and depression with the disease activity of systemic lupus erythematosus

BACKGROUND

Systemic Lupus Erythematosus (SLE) is an autoimmune disease that affects multiple systems and increases the risk of mental disorders such as depression and anxiety. We conducted an observational, single-center, cross-sectional study to investigate the relationship between depression, anxiety, and SLE disease activity.

METHODS

The Patient Health Questionnaire 9 (PHQ-9) was used to assess depression, and the 7-item Generalized Anxiety Disorders Scale was used to assess anxiety (GAD-7). Using the chi-square/exact Fisher's tests, socio-demographic data, clinical and other characteristics of SLE patients were compared between depression or anxiety and non-depression/non-anxiety groups. To identify optimal levels of Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) for predicting depression or anxiety, receiver-operator curves (ROC) were drawn.

RESULTS

Among the 325 patients involved in this study, patients with depression or anxiety had significantly higher SLE activity (p < 0.001), and more frequent musculoskeletal (p < 0.05) and neuropsychiatric symptoms (p < 0.05). Depression and anxiety are more common in the moderate-severe active group than in the inactive-mild active group (depression: OR 3.350, 95%CI 2.015, 5.570, p < 0.001; anxiety: OR 4.085, 95%CI 2.493, 6.692, p < 0.001). The optimal SLEDAI cutoff value of 8.5 predicted depression with a sensitivity of 50.5% and a specificity of 78.4% (AUC 0.660, p < 0.001) and anxiety with a sensitivity of 54.2% and a specificity of 78.4% (AUC 0.684, p < 0.001).

CONCLUSION

SLE disease activity is positively associated with the severity of depression and anxiety. Those patients whose SLEDAI scores are greater than 8.5 are more likely to suffer from mental disorders which require additional attention to them.

Anxiety and depression prevalence and their risk factors in lupus nephritis patients: A case–control study

Introduction

Anxiety and depression exhibit a high prevalence in systemic lupus erythematosus (SLE) patients, while this issue is seldom explored in lupus nephritis (LN). Hence, the current study aimed to investigate the prevalence of anxiety and depression, and the risk factors for these mental disorders in LN patients.

Methods

Fifty LN patients, 50 non‐LN SLE patients, and 50 health control (HCs) were enrolled. The Hospital Anxiety and Depression Scale (HADS) for anxiety (HADS‐A) score and HADS for depression (HADS‐D) score were evaluated.

Results

HADS‐A score was highest in LN patients (median 7.0, interquartile range [IQR]: 6.0–10.0), followed by non‐LN SLE patients (median 6.0, IQR: 5.0–8.0), and lowest in HCs (median 5.0, IQR: 3.0–7.0) (p < .001). Besides, the anxiety rate was most frequent in LN patients (38.0%), followed by non‐LN SLE patients (28.0%), least common in HCs (12.0%) (p = .011). HADS‐D score was highest in LN patients (median 7.5, IQR: 6.0–11.0), followed by non‐LN SLE patients (median 6.0, IQR: 5.0–8.3), and lowest in HCs (median 4.0, IQR: 2.0–6.3) (p < .001). Similarly, the depression rate was most prevalent in LN patients (50.0%), subsequently the non‐LN SLE patients (30.0%), and rarest in HCs (10.0%) (p < .001). Furthermore, in LN patients, age (p = .009), LN activity index (p = .020), alopecia (p = .023), 24 h proteinuria (p = .044), and C‐reactive protein (p = .049) were independently correlated with higher anxiety risk; meanwhile, age (p = .001) and LN activity index (p = .009) were independently correlated with higher depression risk.

Conclusion

Anxiety and depression are highly prevalent, which link to aging, alopecia, inflammation, and severe renal involvement in LN patients.

Prevalence and biopsychosocial factors associated with depressive symptoms among patients living with systemic lupus erythematosus in clinical settings in urban Thailand

BACKGROUND

Depressive symptoms are globally recognized as a significant mental health problem in patients with chronic disease, particularly those with systemic lupus erythematosus (SLE). The purpose of this study was to estimate the prevalence and examine biopsychosocial factors of depressive symptoms among patients with SLE.

METHODS

This cross-sectional study was conducted among 185 participants diagnosed with SLE and received treatment for at least 3 months, aged 18-59 years attending the outpatient clinic of a university hospital, Bangkok, Thailand. Depressive symptoms were measured by the Thai version of the Patient Health Questionnaire-9. We assessed Demographic data, the Systemic Lupus Erythematosus Activity Index, the Systemic Lupus International Collaborating Clinics Damage Index, Numeric Rating Scale, Fatigue Severity Scale, Body Image Scale, and the ENRICHD Social Support Instrument. Data were collected from March to May 2021. Multivariable logistic regression was used to analyze the data.

RESULTS

The proportion of the participants with depressive symptoms was 43.2%, which 8.1% of those patients presented moderate to severe depressive symptoms. In a multivariable logistic regression model, SLE patients with depressive symptoms were more likely to be severe pain (aOR = 12.11, 95% CI: 1.35, 108.46), fatigue (aOR = 2.36, 95%CI: 1.08, 5.14), taking prednisolone ≥15 mg daily (aOR = 5.75, 95%CI: 1.76, 18.80), low satisfied of body image (aOR = 12.49, 95%CI: 2.23, 69.80), and low social support (aOR = 17.96, 95% CI: 1.86, 173.77). Disease flare, organ damage, and family income sufficiency did not significantly increase the risk of depressive symptoms in patients with SLE.

CONCLUSIONS

The findings highlight depressive symptoms in patients with SLE. Therefore, the health professional should be concerned about the perception of body image, level of social support, fatigue, and pain while treating patients with SLE. Public health screening programs to identify depressive symptoms in patients with SLE are needed. In addition, a high dose of prednisolone should be considered if required, along with monitoring.

The Association of Illness Uncertainty and Hope With Depression and Anxiety Symptoms in Women With Systemic Lupus Erythematosus: A Cross-sectional Study of Psychological Distress in Systemic Lupus Erythematosus Women

BACKGROUND

Depression and anxiety are commonly observed psychological symptoms in patients diagnosed with systemic lupus erythematosus (SLE). This study aimed to explore the possible factors that influence depression and anxiety symptoms development in SLE women.

METHODS

This cross-sectional study was conducted between October 2017 and December 2018 in Liaoning, China. Questionnaires including Patient Health Questionnaire-9, Generalized Anxiety Disorder-7, Mishel Uncertainty in Illness Scale for Adults, and Herth Hope Scale were completed by 205 participants. Factors related to depression and anxiety were examined using hierarchical multiple regression analysis, while the effect of hope was examined using structural equation model.

RESULTS

The prevalence of depression and anxiety symptoms in female SLE patients was 79.5% and 86.8%, respectively. Illness uncertainty was strongly positively correlated with depression and anxiety symptoms. In contrast, hope was negatively associated with depression and anxiety symptoms. Up to 66.6% and 59.4% of the variance explained by all the variables was 66.6% in depression symptoms and 59.4% in anxiety symptoms. Interestingly, hope was able to alter the relationship of illness uncertainty with depression and anxiety symptoms.

CONCLUSIONS

While illness uncertainty can increase depression and anxiety symptoms, hope can reduce these symptoms. Therefore, hope-based targeted interventions should be employed to prevent and treat depression and anxiety symptoms among SLE women.

Effect of COVID-19 pandemic on anxiety depression and intention to go to hospital in chronic patients

OBJECTIVE

The aim of this study was to investigate the effects of the COVID-19 pandemic on anxiety depression and intention to go to the hospital in chronic patients.

METHODS

The Bostan Intention to Go to Hospital Scale developed by one researcher (SB) as the data collection tool and the Beck Anxiety-Depression Inventories were used.

RESULTS

Of all patients, 56.8% stated that they would go to the hospital in case of emergency and 28.3% expressed that they did not want to go to the hospital even in this case. 50% of the participants said that they did not want to go to the hospital under any circumstances during the pandemic process. As a result of the correlation analysis, there was an inverse correlation between the anxiety-depression levels and encountering COVID-19 patients and having a relative with COVID-19 (P = .001). Inverse correlation was found between intention to go to hospital and encountering COVID-19 patients (P = .001).

CONCLUSION

It was revealed that chronic patients did not have any intentions to go to hospital during the COVID-19 pandemic and only half of the people were willing to go to the hospital in case of emergency. Anxiety and depression levels were found to increase when COVID-19 patients were encountered or a relative had COVID-19.

Impact of depression on quality of life in systemic lupus erythematosus patients

Background

Depression is common in systemic lupus erythematosus (SLE) and is an unmeasured risk factor, yet its symptoms can be neglected in standard disease evaluations. The purpose of this study was to assess the frequency and the impact of depression on quality of life in SLE patients. We recruited 32 patients with SLE and 15 healthy control volunteers in the study. The following investigations were undertaken in each patient: clinical and rheumatologic assessment, SLE Disease Activity Index-2k (SLEDAI-2k), Beck Depression Inventory (BDI), Short-Form Health Survey (SF-36) questionnaire, and routine laboratory tests.

Results

There was a high percentage of depression (46.9%) in the SLE patients. Regarding quality of life (SF-36), there were significant affection of the physical and mental composite summary domains (PCS and MCS) scores in lupus patients compared with controls (P < 0.000 for both) with the same significant in depressed compared with non-depressed patients. SF-36 subscales (physical function, limit emotional, emotional wellbeing, and social function) were significantly affected in depressed lupus patients compared with non-depressed patients. There was a significant negative correlation between the score of MCS domain of SF-36 with BDI (P < 0.000) while positive correlation between SLEDAI score with depression score. In contrast, there were no significant correlations between MCS or PCS with age, duration of illness, or SLEDAI-2K.

Conclusions

Depression is common in SLE patients and had a negative impact on quality of life particularly on MCS domain and positive correlation with disease severity score.

Trial registration

This study was registered on clinical trial with registration number: NCT03165682 https://clinicaltrials.gov/ct2/show/NCT03165682 on 24 May 2017.

Brain white matter extracellular free-water increases are related to reduced neurocognitive function in systemic lupus erythematosus

OBJECTIVES

Brain white matter (WM) microstructural changes evaluated by diffusion MRI were well documented in patients with systemic lupus erythematosus (SLE). Yet, conventional diffusion tensor imaging technique fails to differentiate WM changes that originate from tissue alterations from those due to increased extracellular free water (FW) related to neuroinflammation, microvascular disruption, atrophy, or other extracellular processes. Here, we sought to delineate changes in WM tissue microstructure and extracellular FW volume and examine their relationships with neurocognitive function in SLE patients.

METHODS

Twenty SLE patients (16 females, aged 36.0±10.6) without clinically-overt neuropsychiatric manifestation and 61 healthy controls (HC) (29 females, aged 29.2±9.4) underwent diffusion MRI and computerized neuropsychological assessments cross-sectionally. The FW imaging method was applied to compare microstructural tissue changes and extracellular FW volume of the brain WM between SLE patients and HC. Association between extracellular FW changes and neurocognitive performance was studied.

RESULTS

SLE patients had higher WM extracellular FW compared to HC (family-wise-error-corrected p < 0.05) while no group difference was found in FW-corrected tissue compartment and structural connectivity metrics. Extracellular FW increases in SLE patients were associated with poorer neurocognitive performance that probed sustained attention (p = 0.022) and higher cumulative glucocorticoid dose (p = 0.0041). Such findings remained robust after controlling for age, gender, IQ, and total WM volume.

CONCLUSIONS

The association between WM extracellular FW increases and reduced neurocognitive performance suggest possible microvascular degradation and/or neuroinflammation in SLE patients with clinically-inactive disease. The mechanistic impact of cumulative glucocorticoids on WM FW deserves further evaluation.

Prevalence and factors associated with depression and anxiety in patients with psoriasis

OBJECTIVE

To identify the prevalence and factors associated with depression and anxiety in patients with psoriasis.

BACKGROUND

Psoriasis is a chronic, non-contagious, autoimmune inflammatory skin disease associated with psychological comorbidities.

DESIGN

A cross-sectional study conducted between March 2017-December 2018 in a dermatology infirmary and outpatient clinic of a public hospital in the inner State of São Paulo (Brazil).

METHODS

We used questionnaires with sociodemographic data and clinical history, the HADS (Hospital Anxiety and Depression Scale), DLQI-BRA (Dermatology Life Quality Index) and PASI (Psoriasis Area Severity Index). The correlations between variables were explored using multivariate techniques. STROBE checklist was applied as the reporting guideline for this study (File S1).

RESULTS

A total of 281 participants were included, of which the majority were female 146 (52%), with a mean age of 52.1 years (SD: 13.8), elementary school 154 (55%), married/cohabiting 209 (74%) and with low income 201 (72%). The median (p25-p75) time with the disease was 14 years (7-23). Regarding the quality of life, 31% of respondents reported being little affected by the disease. The prevalence of depression was 19% and that of anxiety was 36%. The multivariate analysis showed that the variables that influenced the anxiety and depression scores were as follows: DLQI-BRA, income, female sex, illness length and age. For the multiple correspondence analysis, the highest levels of anxiety and depression referred to women, middle age, lower income and low PASI.

CONCLUSION

The prevalence of anxiety and depression symptoms was low. Female sex, income, age, illness length and quality of life were associated with anxiety and depression scores in patients with psoriasis.

RELEVANCE TO CLINICAL PRACTICE

Due to the scarcity of studies in the field of nursing with psoriasis patients, we believe these findings contribute to the reorganisation of the care provided, allowing nurses to timely identify mood disorders such as anxiety and depression and adopt the necessary measures to a service and/or specialised referral.

Pathophysiology of Depression and Novel Sources of Phytochemicals for its Treatment – A Systematic Review

The rising burden of depression, which will soon be the second most common cause of disability in the world, is requesting new ways to treat and prevent it. Due to high number of significant adverse drug reactions of the conventional treatment, the modern pharmaceutical industry is more often turning their focus to novel plant-based solutions. We performed literature research based on standard literature search engines – PubMed, Google Scholar, Science Direct. A standard set of keywords related to our topic e.g. “Depression”, “Mesembrine type alkaloids”, “Narcissus” was used. The review describes the classical monoamine theory of depression and connects it with the newly found biochemical, genetic and morphological alterations associated with the major depressive disorder. The purpose of this review is to highlight the most important aspects of the pathophysiology of depression and to explore the possibilities to use mesembrine-like alkaloids isolated from Narcissus cv. Hawera in its treatment. We describe their effect on brain biochemistry and possible future investigations.

Global mapping of interventions to improve quality of life of patients with depression during 1990-2018

PURPOSE

The number of patients with depressive disordered globally increased and affects people of all ages and countries and has a significant and negative impact on the quality of life (QoL). Depression if left untreated may lead to severe consequences. However, there are several types of effective treatments, but often patients need support from health staff to find suitable treatments. This study aims to examine the global trend of the publications as well as the development of interventions for depressing treatment.

METHODS

We download and analyzed 15,976 scientific research from the Web of Science from 1990 to 2018. A text mining based on Latent Dirichlet and terms' co-occurrence in titles and abstracts to identify hidden research topics and research landscapes.

RESULTS

We found that the number of papers related to non-pharmacological treatment (such as cognitive-behavioral, mindfulness, or family and social support) to improve the QoL of patients with depression has increased. The number of papers on this serious health issue in low-middle income countries (LMICs) was not as high as in high-income countries (HICs).

CONCLUSION

It is necessary to increase support of the treatment of depression in LMICs as well as applied non-pharmacological interventions to patients with depression.

Racism-related stress and psychological distress: Black Women's Experiences Living with Lupus study

Disparate health consequences in African American women with systemic lupus erythematosus include greater severity of physical and psychological distress. Racism-related stress is also related to psychological distress correlates in this population. This study examined the relationships between racism-related experiences, psychological distress, and systemic lupus erythematosus activity in 430 African American women from the Black Women's Experiences Living with Lupus study. The structural equation model suggests that psychological distress mediates the relationship between racism-related stress and systemic lupus erythematosus disease activity. The impact of racism-related stress on systemic lupus erythematosus disease activity may occur primarily through their impact on psychological health variables. Implications for clinical care and future directions are explored.

Epidemiology of Depression and Anxiety in Gout: A Systematic Review and Metaanalysis

OBJECTIVE

To conduct a systematic review of depression and anxiety among patients with gout that specifically evaluates the prevalence, incidence, determinants, and effects of these mental health comorbidities.

METHODS

We conducted a literature search in Medline, Embase, Cochrane Database of Systematic Reviews, CINAHL, and PsycINFO using indexed terms and key words to identify studies reporting on depression/anxiety in patients with gout. This review included full-text articles published in English that reported on patients with gout, evaluated depression/anxiety using a routinely reported measure, and provided estimates or sufficient data on the prevalence, incidence, determinants, or effects of depression/anxiety. Metaanalyses were conducted using random effects models.

RESULTS

Twenty of 901 articles identified through the search strategy met our inclusion criteria. All 20 studies evaluated depression, while only 10 assessed anxiety (50%). Metaanalyses suggest a positive association between mental health disorders and gout, as resultant pooled OR were 1.29 (95% CI 1.07-1.56) for depression and 1.29 (95% CI 0.96-1.73) for anxiety. Findings from four studies reporting on the incidence of depression in patients with gout resulted in a pooled HR of 1.17 (95% CI 1.01-1.36). Significant determinants of depression included number of tophi, frequency of flares, and oligo/polyarticular gout.

CONCLUSION

Our systematic review suggests that depression and anxiety are significantly associated with gout, highlighting the need for future research to focus on the onset of mental disorders after gout diagnosis. We also identify potential targets for intervention.

Determination of depression, anxiety and stress (DAS) levels in patients with atopic dermatitis: a case-control study

The present study was aimed at comparing depression, anxiety and stress (DAS) levels of individuals with atopic dermatitis with those of the individuals without atopic dermatitis, and to examine the DAS levels of the patients with atopic dermatitis in terms of their socio-demographic characteristics. Case control study conducted in a city in western Turkey. The present study in which the relational screening model was used was conducted with patients with atopic dermatitis who presented to the Dermatology Clinic/Polyclinic of a university hospital and healthy subjects, and volunteered to participate in the study. The study conducted between December 2017 and February 2018 included 150 people (75 healthy subjects, 75 patients with atopic dermatitis). To collect the study data, the participants were administered the Socio-demographic Characteristics Questionnaire prepared by the researcher and the Depression, Stress and Anxiety Scale (DASS-42). No significant difference was determined between the mean DASS scores obtained by the atopic dermatitis patients and those obtained by the healthy subjects in the control group (p > 0.05). Of the atopic dermatitis patients, 58.7%, 82.3% and 49.3% were within the normal ranges in terms of the mean scores they obtained from the stress, depression and anxiety subscales respectively. In the present study, the mean scores obtained from the depression and anxiety subscales by working atopic dermatitis patients were higher than those obtained by the nonworking patients (p < 0.05). The mean scores obtained from the stress subscale by the smokers with atopic dermatitis were higher than those obtained by the non-smokers with atopic dermatitis.

The Assessment of Anxiety and Depression and its Associated Factors in SLE

BACKGROUND

Depression and anxiety are common neuropsychiatric complaints in patients with Systemic Lupus Erythematosus (SLE). While numerous studies have been performed to investigate the prevalence, impact, and associated factors of depression and anxiety, current literature presents mixed results. In particular, the prevalence of anxiety and depression varies substantially between studies due to methodological limitations, and heterogeneity in defining anxiety and depression, patient selection, and metrics used. Moreover, there is a lack of studies evaluating the validity, reliability, and interpretability of commonly used screening tools for depression and anxiety in SLE patients.

RESULT AND CONCLUSION

Further investigations should aim to reach a consensus surrounding the role of controversial associated factors in depression and anxiety of SLE patients, while also focusing on the identification of novel factors that have not yet been highlighted in the literature.

Prevalence of Depression in Ankylosing Spondylitis: A Systematic Review and Meta-Analysis

The aim of this study was to provide a summary estimate of depression prevalence among people with ankylosing spondylitis (AS) in comparison to those without AS. A systematic literature search was conducted using PubMed, Embase, PsycINFO, Web of Science, the Cochrane database library, China National Knowledge Infrastructure, and Wanfang Database from their inception to December 2016. The results showed that thirty-one eligible studies involving 8,106 patients were analyzed. Fifteen methods of defining depression were reported. The overall pooled prevalence of depression was 35% (95% CI, 28-43%), with high between-study heterogeneity (I2=98.8%, p<0.001). The relative risk of depression among people with AS was 1.76 (95% CI: 1.21-2.55, eight studies, n=3,006) compared with people without AS. The depression score [standardized mean difference (SMD)=0.43, 95% CI: 0.19-0.67, seven studies, n=549] was higher in AS patients than in controls. The main influence on depression prevalence was the sample size and country of origin. In conclusion, one-third of people with AS experience symptoms of depression. Depression was more prevalent in AS patients than in controls. Further research is needed to identify effective strategies for preventing and treating depression among AS patients.

Resilience of patients with chronic diseases: A systematic review

The purpose of this research was to contribute to the development of a resilience-promoting programme for patients with chronic diseases. A systematic review of literature concerning resilience interventions for patients with chronic diseases was conducted by searching PubMed (including Medline), Science Direct, Web of Science, PsycARTICLES, CINAHL Plus, Embase, and the Cochrane Database for articles featuring the terms "resilience," "resiliency," "resilient," "cancer," "stroke," "heart disease," "diabetes" and "COPD" and published between 8 January 2017 and 15 January 2017. We included all English studies relevant to the topic; however, we excluded: (1) nonrandomised controlled trials and (2) those that mentioned the term "resilience" but did not apply it in their analysis. Seventeen studies-10 on cancer, four on cardiovascular diseases and three on diabetes-were deemed suitable for analysis. We found that, in these studies, (1) diverse definitions of resilience were applied, (2) various intervention durations were used and (3) complex programmes were applied within the resilience-improving programmes. Our research encourages efforts to operationalise the construct of resilience, so it can be applied in clinical settings, and for the development of more systematic intervention programmes.

Prevalence and metric of depression and anxiety in systemic lupus erythematosus: A systematic review and meta-analysis

OBJECTIVES

To systematically review and synthesize literature on 1) the overall prevalence of depression and anxiety in SLE patients in identified studies, and 2) the pooled prevalence per metrics of depression and anxiety in adult SLE patients.

METHODS

This review used (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) PRISMA guidelines and in-depth searches in four databases (1954-2016; Ovid-based Medline, Embase, PsycINFO and CINAHL) to identify articles on the prevalence of depression and/or anxiety in adult SLE patients. Included studies were critically appraised and analyzed. The prevalence of depression and anxiety was studied for all included studies, and whenever possible, pooled prevalence (PP) was determined for more commonly used metrics. Statistical and publication bias was assessed using funnel plots.

RESULT

A total of 3103 references were identified, 226 were selected for detailed review and 72 were included in the final analysis.

OVERALL PREVALENCE

The depression PP, obtained from 69 studies representing 23,386 SLE patients, was 35.0% (95% CI: 29.9%-40.3%). The anxiety PP, obtained from 38 studies representing 4439 SLE patients, was 25.8% (95% CI: 19.2%-32.9%).

PREVALENCE PER METRICS USED

The more commonly used instruments included the Centre for Epidemiological Studies - Depression (CES-D), Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), Hospital Anxiety and Depression Scales (HADS-A/D), and Hamilton Rating Scales for Depression/Anxiety (HAM-D/A)]. The CES-D was utilized in 13 studies including 1856 SLE patients; depression PP was 41.5% (95% CI: 35.1%-48.1%). The BDI was utilized in 14 studies including 1355 SLE patients and the BAI in 3 studies including 489 patients; depression PP was 39.9% (95% CI: 31.1%-49.1) and anxiety PP was 38.4% (95% CI: 34.2%-42.8%). The HADS-D was utilized in 14 studies including 1238 SLE patients and the HADS-A in 12 studies including 1099 patients respectively; its depression PP was 24.4% (95% CI: 19.1%-30.1%) and anxiety PP was 38.3% (95% CI: 29.1%-47.9%). The HAM-D was utilized in 4 studies including 267 SLE patients and the HAM-A in 4 studies including 213 patients respectively; its depression PP was 40.0% (95% CI: 23.0%-59.0%) and anxiety PP was 39.0% (95% CI: 32.0%-45.0%).

CONCLUSION

There was high variability in the prevalence of depression and anxiety, ranging from 8.7%-78.6% and 1.1%-71.4%, respectively. This could be attributed to the lack of consistency in the metrics used and its definition for depression and anxiety in SLE. Studies that used a specific metric, such as the CES-D, BDI or HAM-D, yielded similar depression prevalence. The HADS-D had the lowest prevalence. All metrics of anxiety yielded similar anxiety prevalence.

Cytokine secretion and the risk of depression development in patients with connective tissue diseases

Research in the past two decades has revolutionized our understanding of depressive illnesses. Proinflammatory cytokines have become a point of interest in the interconnecting areas of neuropsychiatric and autoimmune diseases. The cytokine hypothesis of depression suggests that pro-inflammatory cytokines play a primary role in the mediation of the pathophysiological characteristics of major depression, in which an inflammatory process may be induced by external and internal stressors, such as psychological and inflammatory diseases, respectively. The higher prevalence of depression, particularly in patients with chronic autoimmune connective tissue disorders (CTD), suggests that depression may present a dysfunctional adaptation of cytokine-induced sickness, which could manifest in times of an exacerbated activation of the innate immune system. Inflammation is thought to contribute to the development of clinical depression through its ability to induce sickness behaviors corresponding to the neurovegetative features of depression, through the dysregulation of the hypothalamic-pituitary-adrenal axis, alterations in neurotransmitter synthesis and reuptake, and through its involvement in the neuroprogression pathways. This review explores the complex interrelationships in which inflammatory responses alter neuroendocrine and neuropsychological regulation contributing to depressive symptoms in CTD. The prevalence and characteristics of depression, and its correlation to the levels of inflammatory cytokines and disease activity among different CTD will be reviewed.

Prevalence of neuropsychiatric symptoms associated with malformations of cortical development

PURPOSE

Malformations of cortical development (MCD) are structural abnormality of the cortex or brain parenchyma with diverse clinical manifestations. Little is known about the association of psychiatric and behavioral problems in MCD. We aimed to determine prevalence and risk factors of neuropsychiatric symptoms in a cohort of adult patients with MCD.

METHODS

We conducted a retrospective medical records review of 86 adult patients followed at the epilepsy clinic of the Montreal Neurological Hospital. Information on diagnosis of medical and psychiatric disorders, family history, intellectual disability, and psychiatric symptoms was obtained from their medical records.

RESULTS

The cohort (n = 86) had a mean age of 39 ± 14.07 (range: 18-74) years. The three most common MCD subtypes were focal cortical dysplasia (47.7%), periventricular nodular heterotopia (29.1%), and polymicrogyria (16.3%). Overall, prevalence of formally diagnosed psychiatric disorders and psychiatric symptoms were respectively 15.1% and 31.4%. The most frequently described symptoms were anxiety-related (59.3%), followed by irritability (40.7%) and agitation (37.0%). Patients with family psychiatric history (OR: 8.168, 95% CI: 1.44-46.48) and intellectual disability (OR: 5.824, 95% CI: 1.30-26.10) were significantly more likely to have psychiatric symptoms than those without. The prevalence of psychiatric symptoms did not defer between major groups of MCD.

CONCLUSIONS

Neuropsychiatric symptoms are commonly associated with MCD, but psychiatric disorders may be underrecognized given that only half of the patients with psychiatric symptoms were referred for a specialized consultation. The presence of intellectual disability and family psychiatric history may help identify and predict risk of psychiatric manifestations in MCD.

Cognitive Behavioral Treatment for Acute Posttrauma Distress: A Randomized, Controlled Proof-of-Concept Study Among Hospitalized Adults With Burns

OBJECTIVE

(1) To evaluate the feasibility of conducting a randomized controlled trial (RCT) of the Safety, Meaning, Activation and Resilience Training (SMART) intervention vs nondirective supportive psychotherapy (NDSP) in an acutely hospitalized adult survivor of burn injury sample; and (2) to assess the preliminary effect of SMART on acute stress disorder (ASD), posttraumatic stress disorder (PTSD), and major depressive disorder (MDD) symptom reduction as secondary prevention.

DESIGN

Proof-of-concept, parallel group RCT design.

SETTING

Regional burn center.

PARTICIPANTS

Acutely injured, hospitalized adult survivors of burn injury (N=50) were randomly assigned to SMART (n=28) or nondirective supportive psychotherapy (n=22). Due to dropout and missing data, final sample size was 40, SMART (n=21) and nondirective supportive psychotherapy (n=19).

INTERVENTIONS

SMART is a manualized, 4-session cognitive behavioral therapy-based psychological intervention targeting ASD, PTSD, and MDD symptoms. NDSP is a manualized, 4-session protocol.

MAIN OUTCOME MEASURES

Davidson Trauma Scale ([DTS]; diagnostic proxy for ASD and PTSD; clinical cutoff=40, with higher score=higher severity) and the Patient Health Questionnaire-9 ([PHQ-9]; diagnostic proxy for MDD; clinical cutoff=10, with higher score=higher severity) at pretreatment, immediate posttreatment, and 1 month posttreatment.

RESULTS

At baseline, median DTS scores and PHQ-9 scores were above clinical cutoffs and did not differ across groups. At 1 week and 1 month posttreatment, median DTS and PHQ-9 scores were beneath clinical cutoffs in the SMART group; scores remained above clinical cutoffs in the NDSP group at these time points.

CONCLUSIONS

It is feasible to conduct an RCT of SMART in hospitalized adult survivors of burn injury. SMART has the potential to yield clinically significant outcomes. Additional studies are needed to replicate and extend these findings.

Lower vitamin D levels are associated with depression in patients with gout

BACKGROUND

Depression is commonly observed among patients with gout. Low levels of vitamin D have been associated with depression in non-gout subjects. We examined the association of vitamin D levels with depression in patients with gout.

METHODS

We conducted a cross-sectional study of 186 gout patients at the Endocrinology Department of First Affiliated Hospital of Jiaxing University. Levels of serum 25-hydroxyvi-tamin D (25(OH)D) were determined using a competitive protein-binding assay. The 17-item Hamilton Depression Scale was used for screening for depressive symptoms. Diagnosis of depression in gout patients was made in accordance with Diagnostic and Statistical Manual of Mental Disorders, fifth edition criteria for depression. Multivariate analysis was performed using logistic regression models.

RESULTS

Thirty-two gout patients (17.2%) were diagnosed as having depression. Patients with depression showed significantly lower 25(OH)D levels as compared to patients without depression (46.4±19.0 vs 57.0±17.3 nmol/L, P<0.001). Significant differences in 25(OH)D quartiles of gout patients were observed between the patients with depression and the patients without depression (P=0.003). In multivariate analyses, serum 25(OH)D levels (≤40.0 nmol/L) were independently associated with depression in patients with gout (OR 3.833, 95% CI 1.406-10.453, P=0.009).

CONCLUSION

Our study demonstrates an important association between serum vitamin D levels and depression in patients with gout.

Anti-cytokine agents for anhedonia: targeting inflammation and the immune system to treat dimensional disturbances in depression

The etiology of mood disorders is mechanistically heterogeneous, underscoring the need for a dimensional approach to identify and develop targeted treatments in psychiatry. Accumulating evidence implicates inflammation as an important contributor to the pathophysiology of depression and presents the immune system as a viable therapeutic target that may be more proximate to the pathogenic nexus of brain-based disorders in specific subpopulations. Anhedonia is a transdiagnostic (e.g. Parkinson's disease, diabetes mellitus, rheumatic diseases), yet specific, and clinically relevant symptom dimension subserved by well-characterized neurobiological and neurophysiological substrates of the positive valence systems (PVS). Brain circuits, nodes, and networks, as well as cellular and molecular pathways (e.g. dopaminergic transmission; excitotoxicity; synaptic plasticity), subserving anhedonia are preferentially affected by inflammatory processes. To our knowledge, no published randomized, controlled clinical trial in populations with mood disorders has, to date, primarily sought to determine the effects of an anti-inflammatory agent on PVS functions or pathophysiology. Three ongoing clinical trials aim to investigate the effects of anti-TNF-alpha biologic infliximab on measures of anhedonia [ClinicalTrials.gov identifier: NCT02363738], motivational behavior and circuitry [ClinicalTrials.gov identifier: NCT03006393], and glutamatergic changes in the basal ganglia [ClinicalTrials.gov identifier: NCT03004443] in clinical populations with unipolar or bipolar depression. Positive results would further instantiate the relevance of inflammatory processes and the immune system in the pathophysiology of mood disorders and provide the impetus to develop scalable treatments targeting inflammation and the immune system to mitigate transdiagnostic, dimensional disturbances in brain-based disorders.

The association of disease activity, pro-inflammatory cytokines, and neurotrophic factors with depression in patients with rheumatoid arthritis

Inflammation and trophic factors (brain-derived neurotrophic factor [BDNF], vascular endothelial growth factor, glial cell line-derived neurotrophic factor, and insulin-like growth factor-1) are associated with depression in the general population. Rheumatoid arthritis (RA) is a chronic representative inflammatory autoimmune disease; however, the association of disease activity, pro-inflammatory cytokines, and neurotrophic factors with depression has not been sufficiently investigated. Therefore, we determined the prevalence of depression and risk factors for depression and deterioration of depressive symptoms in RA patients. In addition, we analyzed the association between disease activity, pro-inflammatory cytokines, trophic factors, and depression in RA (N = 474). Demographic and laboratory data were examined, and routine assessment of patient index data 3 (RAPID 3) and disease activity score 28-joint count C-reactive protein (DAS 28-CRP) was performed to assess disease activity of RA. Depression was measured using the Korean version of the Beck Depression Inventory-second edition (K-BDI II). A K-BDI score ≥18 was considered the cut-off for depression in accordance with a previous validation study. The serum level of pro-inflammatory cytokines and neurotrophic factors was assessed by enzyme-linked immune sorbent assay. The prevalence of depression was 32.4% in patients with RA. The severity of disease activity of RA (RAPID 3 score [OR 2.34; 95% confidence interval, CI 1.22-4.51], DAS 28-CRP [≥3.2] [OR 1.60, 95% CI 1.01-2.53]) and severity of fatigue (OR 1.26 95% CI 1.15-1.38) were associated with depression and deterioration of depressive symptoms in the multivariate analysis. Among the components of RAPID 3 and DAS 28-CRP, patient assessment for global health and abilities for daily performance were more related to depression. The level of pro-inflammatory cytokines (IL-1β, IL-6, TNF-alpha) was not related to depression. The level of BDNF was significantly lower in RA patients with depression and was negatively correlated with K-BDI II score. Depression was related with the level of fatigue, low expression of BDNF, and high RA disease activity, which was associated with impaired ability to perform activities of daily life. Strict control of fatigue and disease activity to improve one's capacity to perform daily life activities would be important to regulate depression. The level of BDNF might be one of the possible biomarkers to predict or monitor depression in patients with RA.

Prevalence of anxiety in patients with mild cognitive impairment: A systematic review and meta-analysis

BACKGROUND

Prevalence rates of anxiety in patients with mild cognitive impairment (MCI) varied widely across studies and may confer a higher likelihood of progression to dementia. Our aim was to estimate the prevalence of anxiety in MCI and identify reasons for heterogeneity in the reported results.

METHODS

A computerized search in PubMed, EMBASE, and Psyc INFO for studies on anxiety in MCI was performed up to March 2017. The overall prevalence of anxiety in patients with MCI was pooled using a random-effects model. Heterogeneity was explored using stratification (recruitment resource; method of anxiety diagnosis; method of MCI diagnosis; and region) and random-effects meta-regression.

RESULTS

Of 2494 unique abstracts, 290 were selected for full-text review, and 39 studies, representing 10,587 patients, met all inclusion criteria. The overall pooled prevalence of depression in patients with MCI was 21.0% (95% CI, 16.2-26.7) with significant heterogeneity present (I² = 97.2%, p < 0.001). When stratified by source, the prevalence of anxiety in patients with MCI in community-based samples was 14.3% (95% CI, 9.7-20.5) and was 31.2% (95% CI, 23.6-40.0) in clinic-based samples, which was significantly different (p < 0.01). The prevalence of anxiety estimates also differed significantly, when stratification by the method of anxiety diagnosis (p < 0.01). However, the criteria used for MCI diagnosis and geographical region did not significantly influence the prevalence estimate.

LIMITATIONS

We did not consider the usage of anti-anxiety drugs and language bias.

CONCLUSIONS

The prevalence of anxiety in patients with MCI was common and variability in prevalence of anxiety across studies can be attributed partly to the source of the sample and method of anxiety diagnosis. Further research is needed to identify sources of heterogeneity.

Sexual function, anxiety and depression in women with benign breast disease. A case-control study

INTRODUCTION

Sexual dysfunction is highly prevalent, affecting 40% of the female population. The incidence of such dysfunction is known to be higher among women with malignant breast disease and in patients with depression or anxiety. However, there are few data regarding the prevalence of sexual dysfunction among women with benign breast disease (BBD).

OBJECTIVE

To evaluate the incidence of sexual dysfunction, depression and anxiety among women with BBD, in comparison with that observed for healthy women.

METHOD

We evaluated the incidence of sexual dysfunction in 60 patients with benign breast disease (fibroadenomas, breast cysts, breast pain and phyllodes tumor) and 69 healthy women (control group). Participants completed the Sexual Quotient Questionnaire for Females (SQQ-F), the Beck Depression Inventory and the Beck Anxiety Inventory. Statistical analysis revealed that depression and anxiety were comparable between BBD and control groups (10.3 vs. 20.3% and 38.7 vs. 34.3%, respectively, p>0.05). The mean SQQ-F score (65.6±22.7 vs. 70.1±16.8; p>0.05) and sexual dysfunction (33.3 vs. 25.4%; p=0.324) were similar between BBD and control groups.

CONCLUSION

We found no differences between women with BBD and healthy women in terms of the incidence of sexual dysfunction, anxiety and depression. Nevertheless, given the high prevalence of this condition, it is important to assess sexual quality of life, as well as overall quality of life, in women with BBD.

Poststroke emotional disturbances and a tryptophan hydroxylase 2 gene polymorphism

Objectives

Emotional dysfunction is a common finding in stroke patients. Despite reports on serotonergic involvement in the etiology of poststroke emotional dysfunction (PSED), the role of serotonin synthesizing tryptophan hydroxylase 2 (TPH2) genes in the development of PSED remains unclear.

Methods

Genotyping of TPH2 rs4641528 and rs10879355 was performed from genomic DNA of 383 stroke patients collected previously and stored at -70°C. Potential associations between TPH2 genes and poststroke depression (PSD), poststroke emotional incontinence (PSEI), and poststroke anger proneness (PSAP) were investigated 3 months poststroke.

Results

Among the 383 patients, 69 (18%) had PSD, 41 (11%) had PSEI, and 93 (24%) had PSAP. The TPH2 rs4641528 genotype frequencies differed significantly between patients with and without either PSD or PSEI, although no significant differences were found between the patients with and without PSAP. In multiple logistic regression analysis, PSD was related to the National Institutes of Health Stroke Scale (NIHSS) score at admission (95% confidence interval [CI]: 1.047-1.230, p < .01), modified Rankin scale score at 3 months (95% CI: 0.135-0.848, p < .05), and TPH2 rs4641528 C allele (95% CI: 1.039-5.631, p < .05), whereas PSEI was associated only with the NIHSS score at admission (95% CI: 1.053-1.259, p < .01) and the TPH2 rs4641528 C allele (95% CI: 1.029-11.678, p < .05).

Conclusions

Our findings suggest that the TPH2 rs4641528 C allele may play a role in the pathogenesis of PSD and PSEI but not PSAP in Korean stroke patients.

Health-related quality of life in gout in primary care: Baseline findings from a cohort study

Objectives

To examine gout-related, comorbid, and sociodemographic characteristics associated with generic and disease-specific health-related quality of life (HRQOL) in gout.

Methods

Adults with gout from 20 general practices were mailed a questionnaire containing the Health Assessment Questionnaire-Disability Index (HAQ-DI), Short-Form-36 Physical Function subscale (PF-10), Gout Impact Scale (GIS), and questions about gout-specific, comorbid and sociodemographic characteristics. Variables associated with HRQOL were examined using multivariable linear regression models.

Results

A total of 1184 completed questionnaires were received (response 65.9%). Worse generic and gout-specific HRQOL was associated with frequent gout attacks (≥5 attacks PF-10 β = −4.90, HAQ-DI β = 0.14, GIS subscales β = 8.94, 33.26), current attack (HAQ-DI β = 0.15, GIS β = −1.94, 18.89), oligo/polyarticular attacks (HAQ-DI β = 0.11, GIS β = 0.78, 7.86), body pain (PF-10 β = −10.68, HAQ-DI β = 0.29, GIS β = 2.61, 11.89), anxiety (PF-10 β = −1.81, HAQ-DI β = 0.06, GIS β = 0.38, 1.70), depression (PF-10 β = −1.98, HAQ-DI β = 0.06, GIS 0.42, 1.47) and alcohol non-consumption (PF-10 β = −16.10, HAQ-DI β = 0.45). Gout-specific HRQOL was better in Caucasians than non-Caucasians (GIS β = −13.05, −13.48). Poorer generic HRQOL was associated with diabetes mellitus (PF-10 β = −4.33, HAQ-DI β = 0.14), stroke (PF-10 β = −12.21, HAQ-DI β = 0.37), renal failure (PF-10 β = −9.43, HAQ-DI β = 0.21), myocardial infarction (HAQ-DI β = 0.17), female gender (PF-10 β = −17.26, HAQ-DI β = 0.43), deprivation (PF-10 β = −7.80, HAQ-DI β = 0.19), and body mass index ≥35 kg/m² (PF-10 β = −6.10, HAQ-DI β = 0.21).

Conclusions

HRQOL in gout is impaired by gout-specific, comorbid, and sociodemographic characteristics, highlighting the importance of comorbidity screening and early urate-lowering therapy. Both gout-specific and generic questionnaires identify the impact of disease-specific features on HRQOL but studies focusing on comorbidity should include generic instruments.

Prevalence of depression and depressive symptoms among outpatients: a systematic review and meta-analysis

OBJECTIVES

Depression and depressive symptoms are common mental disorders that have a considerable effect on patients' health-related quality of life and satisfaction with medical care, but the prevalence of these conditions varies substantially between published studies. The aim of this study is to conduct a systematic review and meta-analysis to provide a precise estimate of the prevalence of depression or depressive symptoms among outpatients in different clinical specialties.

DESIGN

Systematic review and meta-analysis.

DATA SOURCES AND ELIGIBILITY CRITERIA

The PubMed and PsycINFO, EMBASE and Cochrane Library databases were searched to identify observational studies that contained information on the prevalence of depression and depressive symptoms in outpatients. All studies included were published before January 2016. Data characteristics were extracted independently by two investigators. The point prevalence of depression or depressive symptoms was measured using validated self-report questionnaires or structured interviews. Assessments were pooled using a random-effects model. Differences in study-level characteristics were estimated by meta-regression analysis. Heterogeneity was assessed using standard χ² tests and the I² statistic. The study protocol has been registered with PROSPERO under number CRD42017054738.

RESULTS

Eighty-three cross-sectional studies involving 41 344 individuals were included in this study. The overall pooled prevalence of depression or depressive symptoms was 27.0% (10 943/41 344 individuals; 95% CI 24.0% to 29.0%), with significant heterogeneity between studies (p<0.0001, τ²=0.3742, I²=96.7%). Notably, a significantly higher prevalence of depression and depressive symptoms was observed in outpatients than in the healthy controls (OR 3.16, 95% CI 2.66 to 3.76, I²=72.0%, χ ² =25.33). The highest depression/depressive symptom prevalence estimates occurred in studies of outpatients from otolaryngology clinics (53.0%), followed by dermatology clinics (39.0%) and neurology clinics (35.0%). Subgroup analyses showed that the prevalence of depression and depressive symptoms in different specialties varied from 17.0% to 53.0%. The prevalence of depression and depressive symptoms was higher among outpatients in developing countries than in outpatients from developed countries. Moreover, the prevalence of depression and depressive symptoms in outpatients slightly decreased from 1996 to 2010. Regarding screening instruments, the Beck Depression Inventory led to a higher estimate of the prevalence of depression and depressive symptoms (1316/4702, 36.0%, 95% CI 29.0% to 44.0%, I²=94.8%) than the Hospital Anxiety and Depression Scale (1003/2025, 22.0%, 95% CI 12.0% to 35.0%, I²=96.6%).

CONCLUSION

Our study provides evidence that a significant proportion of outpatients experience depression or depressive symptoms, highlighting the importance of developing effective management strategies for the early identification and treatment of these conditions among outpatients in clinical practice. The substantial heterogeneity between studies was not fully explained by the variables examined.

Diagnosing and attributing neuropsychiatric events to systemic lupus erythematosus: time to untie the Gordian knot?

Neurological and psychiatric syndromes, collectively referred to as NPSLE, occur frequently in SLE. The frequency of NPSLE varies from 21 to 95%; however, only 13-38% of neuropsychiatric (NP) events could be attributable to SLE in the NPSLE SLICC inception cohort. This variability in the frequency of NPSLE is attributable to the low specificity of the ACR case definitions for SLE-attributed NP syndromes, inclusion of minor NP events in the ACR nomenclature, difficulty in ascertainment of NP events and diverse experience of rheumatologists in the clinical assessment of NP events. Making the correct and early attribution of NP events to SLE is important to institute appropriate immunosuppressive treatment for favourable outcomes. Various attribution models using composite decision rules have been developed and used to ascribe NP events to SLE. This review will focus on the various clinical presentations, diagnostic work-up and attributions of the common NPSLE syndromes, including other NP events not included in the ACR nomenclature but which have come to attention in recent years.

Serum levels of brain-derived neurotrophic factor are associated with depressive symptoms in patients with systemic lupus erythematosus

OBJECTIVE

The aim of this study was to explore potential relationships between serum BDNF levels and depression in systemic lupus erythematosus (SLE) patients.

METHODS

We included 208 consecutive SLE patients and 100 age-and sex-matched healthy controls. The presence of depressive symptoms was determined through the Beck Depression Inventory-II (BDI-II) score.

RESULTS

The serum BDNF levels were significantly (P<0.0001) higher in SLE patients as compared to normal controls. There was a negative correlation between levels of BDNF and the SLE disease activity index 2000 (SLEDAI-2K) (r=-0.349, P<0.0001). Depression (defined as BDI-II score≥18) was identified in 54 SLE patients (26.0%, 95%CI: 20%-31.9%). The serum BDNF levels were significantly lower in depression patients at the time of admission as compared with patients without depression [27.6(IQR, 23.2-30.4)ng/ml vs. 36.2(IQR, 31.7-42.3)ng/ml; P<0.0001]. Compared with the first quartile of serum BDNF levels, the second quartile OR for depression was 0.72 (95% CI, 0.61-0.80, P=0.033). For the third and fourth quartiles, it was 0.42 (95% CI, 0.33-0.52, P=0.002) and 0.16 (95% CI, 0.09-0.24; P<0.001).

CONCLUSION

Serum BDNF levels are decreased in SLE patients with depressive symptoms. In SLE, serum BNDF levels are independently associated with depressive disorders, suggesting the role of neurotrophic factors in depression.

Prevalence of depression and anxiety in systemic lupus erythematosus: a systematic review and meta-analysis

BACKGROUND

Systemic lupus erythematosus (SLE) patients are at high risk for depression and anxiety. However, the estimated prevalence of these disorders varies substantially between studies. This systematic review aimed to establish pooled prevalence levels of depression and anxiety among adult SLE patients.

METHODS

We systematically reviewed databases including PubMed, Embase, PsycINFO, and the Cochrane database library from their inception to August 2016. Studies presenting data on depression and/or anxiety in adult SLE patients and having a sample size of at least 60 patients were included. A random-effect meta-analysis was conducted on all eligible data.

RESULTS

A total of 59 identified studies matched the inclusion criteria, reporting on a total of 10828 adult SLE patients. Thirty five and thirteen methods of defining depression and anxiety were reported, respectively. Meta-analyses revealed that the prevalence of major depression and anxiety were 24% (95% CI, 16%-31%, I² = 95.2%) and 37% (95% CI, 12%-63%, I² = 98.3%) according to clinical interviews. Prevalence estimates of depression were 30% (95% CI, 22%-38%, I² = 91.6%) for the Hospital Anxiety and Depression Scale with thresholds of 8 and 39% (95% CI, 29%-49%, I² = 88.2%) for the 21-Item Beck Depression Inventory with thresholds of 14, respectively. The main influence on depression prevalence was the publication years of the studies. In addition, the corresponding pooled prevalence was 40% (95% CI, 30%-49%, I² = 93.0%) for anxiety according to the Hospital Anxiety and Depression Scale with a cutoff of 8 or more.

CONCLUSIONS

The prevalence of depression and anxiety was high in adult SLE patients. It indicated that rheumatologists should screen for depression and anxiety in their patients, and referred them to mental health providers in order to identify effective strategies for preventing and treating depression and anxiety among adult SLE patients.

Body mass index moderates the relationship between C-reactive protein and depressive symptoms: evidence from the China Health and Retirement Longitudinal Study

The present study aimed to investigate the role of abnormal body mass index (BMI, kg/m²) in the depression-CRP (C-reactive protein) relationship in a healthy middle-aged and elderly Chinese population. Analytical samples were drawn from the China Health and Retirement Longitudinal Study (CHARLS), and participants were categorized by different BMI levels. Depressive subtypes were evaluated both at baseline and follow-up using the Center for Epidemiology Studies Depression scale. Hs-CRP and other variables were measured at baseline. Multiple linear regression analyses were used to evaluate the cross-sectional and longitudinal relationship between depression and baseline hs-CRP. Depression was significantly negatively associated with BMI (ρ = −0.077, p < 0.0001), with underweight associated with worse depressive symptoms than other BMI groups. Both cross-sectional and longitudinal associations between serum hs-CRP and depressive subtypes were significantly positive in the underweight group (p < 0.05). However, in the other BMI groups (from normal weight to obesity), the CRP-depression relationship was no longer significant (p > 0.05). The significant relationship between CRP and depression in the underweight group suggested that not only obesity but also a low BMI could explain a substantial portion of the inflammation-depression link.

Early cerebral volume reductions and their associations with reduced lupus disease activity in patients with newly-diagnosed systemic lupus erythematosus

We examined if cerebral volume reduction occurs very early during the course of systemic lupus erythematosus (SLE), and observed prospectively whether gray (GMV) and white matter volumes (WMV) of the brain would improve with lowered SLE disease activity. T1-weighted MRI brain images were obtained from 14 healthy controls (HC) and 14 newly-diagnosed SLE patients within 5 months of diagnosis (S1) and after achieving low disease activity (S2). Whole brain voxel-based morphometry was used to detect differences in the GMV and WMV between SLE patients and HC and those between SLE patients at S1 and S2. SLE patients were found to have lower GMV than HC in the middle cingulate cortex, middle frontal gyrus and right supplementary motor area, and lower WMV in the superior longitudinal fasciculus, cingulum cingulate gyrus and inferior fronto-occipital fasciculus at both S1 and S2. Whole-brain voxel-wise analysis revealed increased GMV chiefly in the prefrontal regions at S2 compared to S1 in SLE patients. The GMV increase in the left superior frontal gyrus was significantly associated with lowered SLE disease activity. In conclusion, GMV and WMV reduced very early in SLE patients. Reduction of SLE disease activity was accompanied by region-specific GMV improvement in the prefrontal regions.

Depressive symptoms are associated with tumor necrosis factor alpha in systemic lupus erythematosus

BACKGROUND

Tumor necrosis factor alpha (TNF-α) is deeply related to pathogenesis of neurodevelopmental disorders, especially depression. The aim of this study was to explore potential relationships between sera TNF-α levels and mood and anxiety disorders in systemic lupus erythematosus (SLE) patients.

METHODS

We included 153 consecutive SLE patients (women 148; median age 30; range 10-62) and 40 (women 37; mean age 28.5; range 12-59) age- and sex-matched healthy controls. Mood and anxiety disorders were determined through Beck Depression and Beck Anxiety Inventory. SLE patients were further assessed for clinical and laboratory SLE manifestations. TNF-α levels were measured by enzyme-linked immunosorbent assay using commercial kits.

RESULTS

Depressive symptoms were identified in 70 (45.7 %) SLE patients and in 10 (25 %) healthy controls (p < 0.001). Anxiety symptoms were identified in 93 (60.7 %) SLE patients and in 16 controls (40 %) (p < 0.001). Sera TNF-α levels were increased in SLE patients with depressive symptoms (p < 0.001) and with anxiety symptoms (p = 0.014). A direct correlation between the severity of depressive symptoms and sera TNF-α levels (r = 0.22; p = 0.003) was observed. TNF-α levels were significantly increased in patients with active disease (p = 0.012). In addition, we observed a correlation between sera TNF-α levels and disease activity (r = 0.28; p = 0.008). In the multivariate analysis, sera TNF-α levels were independently associated with depressive symptoms (t = 3.28; 95 % CI 1.08-2.2; p = 0.002).

CONCLUSIONS

Sera TNF-α levels are increased in SLE patients with mood and anxiety disorders. In SLE, sera TNF-α levels are independently associated with mood disorders. The etiology of mood disorders is still debated in SLE, but our findings suggest the presence of immunological basis for depression in SLE.

Health-related quality of life, psychological well-being, and sexual function in patients with benign prostatic hyperplasia after prostatic surgery

AIMS AND BACKGROUND

Patients with benign prostatic hyperplasia (BPH) may receive prostatic surgery due to severe lower urinary tract symptoms (LUTS). This study aimed to investigate the health-related quality of life (HRQoL), psychological well-being, and sexual function of patients with BPH after prostatic surgery and identify the predictors of HRQoL among this group of patients.

METHODS

This was a cross-sectional, descriptive, correlational study. A convenience sample of 94 participants was recruited from a urology center in a tertiary public hospital in Singapore. The 12-item Short Form Health Survey version 2 (SF-12v2), International Prostate Symptom Score (IPSS), Hospital Anxiety and Depression Scale (HADS), and 5-item International Index of Erectile Function (IIEF-5) were used to measure the study variables.

RESULTS

Compared to the general population norms and the findings of similar studies conducted in western countries, this group of patients reported poorer physical health but better mental health as assessed by SF-12v2. Despite the prostatic surgery, over a quarter of the patients experienced moderate LUTS, and 13.8% experienced severe erectile dysfunction. Multiple linear regression analysis identified that LUTS (B=-0.51, p=0.02) and maximum flow rate (B=-0.23, p=0.02) predicted poor physical health, accounting for 45.9% of variance, while HADS-Anxiety (B=-1.07, p<0.01) and LUTS (B=-0.32, p=0.03) predicted poor mental health, accounting for 57.2% of variance.

CONCLUSION

The physical health of BPH patients with prostatic surgery was poor, with many suffering moderate LUTS and sexual dysfunction. Special attention should be given to those patients with severe LUTS who have a low maximum flow rate or have anxiety symptoms.

Psychological distress in corticosteroid-naive patients with systemic lupus erythematosus: A prospective cross-sectional study

OBJECTIVE

Psychological distress, such as depression and anxiety, has been intensively studied in patients with systemic lupus erythematosus (SLE). However, those studies have mostly included patients who were treated with corticosteroids, which might themselves induce mood disturbances. We investigated psychological distress in corticosteroid-naive patients with SLE who did not exhibit any overt neuropsychiatric manifestations.

METHODS

Forty-three SLE in-patients with no current or past abnormal neuropsychiatric history participated in the study. Patients and 30 healthy control subjects with similar demographic and personality characteristics were administered a comprehensive battery of psychological/neuropsychological tests. The Profile of Mood States (POMS) was used to assess depression and anxiety. Results of clinical, laboratory, and neurological tests were compared with regard to their presence.

RESULTS

Prevalence of depression was higher in patients (n = 11, 25.6%) than in controls (n = 2, 6.7%; p = 0.035), although prevalence of anxiety did not differ across groups (patients: 34.9%, n = 15; controls: 16.7%, n = 5; p = 0.147). Using multiple logistic regression analysis, we identified avoidance coping methods (OR, 1.3; 95% CI 1.030-1.644; p = 0.027) as an independent risk factor for depression.

CONCLUSION

Our results indicate that depression presents more frequently in corticosteroid-naive patients with early-stage, active SLE than in the normal population, but anxiety does not. Depression may be related to psychological reactions to suffering from the disease.

Active disease is independently associated with more severe anxiety rather than depressive symptoms in patients with systemic lupus erythematosus

Objective

The inter-correlation between and co-existence of depression and anxiety may engender inconsistency in addressing the relationship between the severity of depression and disease activity of systemic lupus erythematosus (SLE). We aimed at identifying whether lupus disease activity is independently associated with depression and anxiety in lupus patients.

Methods

Adult lupus patients were assessed for the severity of depressive and anxiety symptoms and lupus disease activity by using the Hospital Anxiety and Depression Scale (HADS) and the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI), respectively. Age- and gender-matched healthy controls (HCs) were recruited for comparison. Prevalence and severity of depressive and anxiety symptoms were compared between lupus patients and HCs. Independent relationships between the severity of anxiety (HADS-Anxiety) and depressive (HADS-Depression) symptoms, and SLEDAI were studied with regression models.

Results

In total, 110 lupus patients and 110 HCs were studied. Lupus patients had significantly higher HADS scores than HCs (10.82 ± 6.5 vs 7.34 ± 4.9, p < 0.001). Significantly more lupus patients had anxiety (40.9 vs 21.8%, p = 0.002) and depressive symptoms (15.5 vs 6.4%, p = 0.025) than HCs. Multiple linear regression analyses revealed that SLEDAI (β = 0.160, p = 0.016), calcineurin inhibitor non-use (β = –1.929, p = 0.041) and past cyclophosphamide non-use (β = –1.603, p = 0.039) independently predicted HADS-Anxiety amongst lupus patients even after adjusting for HADS-Depression. Conversely, SLEDAI (β = 0.014, p = 0.834) lost its significant univariate correlation with HADS-Depression after controlling for HADS-Anxiety and other covariates.

Conclusion

Anxiety is more common in lupus patients than in HCs, and its severity is independently associated with more active SLE regardless of the presence or absence of concomitant depression.

Lifestyle habits and fatigue among people with systemic lupus erythematosus and matched population controls

OBJECTIVE

The objective of this paper is to identify clusters of fatigue in patients with systemic lupus erythematosus (SLE) and matched controls, and to analyze these clusters with respect to lifestyle habits, health-related quality of life (HRQoL), anxiety and depression.

METHODS

Patients with SLE (n = 305) and age- and gender-matched population controls (n = 311) were included. Three measurements of fatigue (Fatigue Severity Scale (FSS), Vitality (VT, from SF-36) and Multidimensional Assessment of Fatigue scale (MAF) and hierarchic cluster analysis were used to define clusters with different degrees of fatigue. Lifestyle habits were investigated through questionnaires. HRQoL was assessed with the SF-36 and anxiety/depression with the Hospital Anxiety and Depression Scale.

RESULTS

Three clusters, denominated "High," "Intermediate" and "Low" fatigue clusters, were identified. The "High" contained 80% patients, and 20% controls (median; VT 25, FSS 5.8, MAF 37.4). These had the most symptoms of depression (51%) and anxiety (34%), lowest HRQoL (p < 0.001) and they exercised least frequently. The "Intermediate" (48% patients and 52% controls) (median; VT 55, FSS 4.1, MAF 23.5) had similarities with the "Low" regarding sleep/rest whereas social status and smoking were closer to the "High." The"Low" contained 22% patients and 78% controls (median; VT 80, FSS 2.3, MAF 10.9). They had the highest perceived HRQoL (p < 0.001), least symptoms of anxiety (10%), no depression, smoked least (13%) and reported the highest percentage (24%) of exercising ≥ 3 times/week.

CONCLUSION

Fatigue is common, but not a general feature of SLE. It is associated with depression, anxiety, low HRQoL and less physical exercise. Patients with SLE and population controls with a healthy lifestyle reported lower levels of fatigue. Whether lifestyle changes can reduce fatigue, which is a major problem for a majority of SLE patients, needs to be further explored.

Dysfunctional cortico-basal ganglia-thalamic circuit and altered hippocampal-amygdala activity on cognitive set-shifting in non-neuropsychiatric systemic lupus erythematosus

OBJECTIVE

To explore sequential brain activities throughout cognitive set-shifting, which is critical to understanding the basic pathophysiology of cognitive dysfunction, in patients with new-onset systemic lupus erythematosus (SLE) without neuropsychiatric symptoms.

METHODS

Fourteen patients with new-onset SLE but without neuropsychiatric symptoms and 14 healthy controls matched for age, sex, education level, and intelligence quotient with the patients performed a cognitive set-shifting task derived from the Wisconsin Card Sorting Test while they were undergoing event-related functional magnetic resonance imaging of the brain. Blood oxygen level-dependent signals were compared between different stages of cognitive set-shifting in the lupus patients and in the healthy subjects.

RESULTS

Lupus patients and healthy subjects demonstrated comparable cognitive function performance, but the cortico-basal ganglia-thalamic-cortical circuit and amygdala-hippocampus coupling, which were involved in response inhibition and active forgetting-learning dynamics, respectively, were demonstrated to be compromised in patients with SLE. Moreover, an increase in contralateral cerebellar-frontal activity was found to compensate for the compromised cortico-basal ganglia-thalamic-cortical circuit in lupus patients in order to maintain their cognitive test performance as comparable to that of the healthy subjects.

CONCLUSION

Our study revealed significant differences in the sequential brain signals during cognitive set-shifting between patients with SLE without neuropsychiatric symptoms and healthy subjects. The results prompt further in-depth investigation for the functional neural basis of cognitive dysfunction involving the aforementioned neural circuits and compensatory pathways in patients with SLE.

Psychological interventions for patients with rheumatic diseases and anxiety or depression

The prevalence of clinical anxiety and clinical depression in rheumatic diseases is about twice the prevalence seen in the general population. At a milder level, the occurrence of psychological distress that does not fulfil diagnostic criteria of anxiety and depression is even higher. Evidence indicates that this high prevalence is multifactorial. Correlational studies suggest that possible factors for anxiety and depression include the suffering accompanying somatic symptoms, functional limitations, pro-inflammatory cytokines, helplessness due to the uncontrollable, unpredictable and progressive nature of the disease, and other factors associated with having a chronic disease. This article reviews the prevalence and diagnosis of anxiety and depression in rheumatic diseases and it examines the contents and the impact of psychological interventions to address these difficulties for patients.

Serum tumour necrosis factor-alpha is associated with poor health-related quality of life and depressive symptoms in patients with systemic lupus erythematosus

OBJECTIVES

While patients with systemic lupus erythematosus (SLE) have poorer health-related quality of life (HRQoL) and are more depressed than healthy people, the impact of proinflammatory cytokines, particularly tumour necrosis factor-alpha (TNFα), on these unfavourable psychosocial parameters is unclear. We aim to explore potential relationships between lupus-related proinflammatory cytokines, HRQoL and depressive symptoms in patients with SLE.

METHODS

Patients with SLE and age-matched healthy subjects were assessed for HRQoL and depressive and anxiety symptoms by the Short Form Health Survey-36 (SF-36) and Hospital Anxiety and Depression Scale (HADS) respectively. Using multiplex immunoassay, a panel of serum proinflammatory cytokines including TNFα, interleukin (IL)-1β, IL-6, IL-17, IL-23 and IL-33 were determined and compared between both groups. Independent associations between SF-36, serum proinflammatory cytokine levels and HADS scores were studied by regression models.

RESULTS

In total, 54 patients and 54 healthy controls were studied. Lupus patients had significantly poorer HRQoL (p < 0.001) and were significantly more depressed (p = 0.006) and anxious (p = 0.022) than their healthy counterparts. Amongst the proinflammatory cytokines studied, serum TNFα was significantly higher in lupus patients (p < 0.001). After multivariate adjustment, higher serum TNFα (β = -0.224, p = 0.047) remained significantly associated with lower SF-36, along with smoking (β = -0.253, p = 0.014) and more severe depressive symptoms (β = -0.433, p = 0.002). In healthy subjects, serum TNFα was associated with depressive symptoms but not with SF-36.

CONCLUSIONS

Higher serum TNFα level is independently associated with poorer HRQoL and more severe depressive symptoms in SLE patients. These associations suggest a potential impact of inflammatory response on depressive symptoms and the quality of life in patients with SLE.

Prevalence and predictors of depression in patients with systemic lupus erythematosus: a cross-sectional study

OBJECTIVE

The purpose of this study was to estimate the prevalence and examine the predictors of depression in patients with systemic lupus erythematosus (SLE).

METHODS

This cross-sectional study was conducted in the rheumatology clinic of a university hospital. All SLE patients that met the revised American College of Rheumatology (ACR) classification were included in the study. Sociodemographic data and medications were recorded. Disease activity for SLE was assessed with the Mexican-SLE Disease Activity Index (Mex-SLEDAI). All subjects were screened for anxiety and depression by using the Hamilton Anxiety Rating Scale (HAM-A) and the 17-item version of the Hamilton Depression Rating Scale (HAM-D17). Multiple linear regression analyses were used to determine predictors of depressive disorder.

RESULTS

A total of 62 SLE (61 females and 1 male) patients participated in the study. Based on HAM-D17 and HAM-A, rates of depression and anxiety in SLE patients were 45.2% and 37.1%, respectively. The multiple linear regression analysis revealed that HAM-A score and younger age were significant predictors of depression in SLE patients.

CONCLUSION

The findings suggest that depression and anxiety are common in SLE patients. In addition, higher levels of anxiety and a younger age may increase the risk of depression. Because of the small sample size, further studies should be conducted to confirm these results.

A prospective functional MRI study for executive function in patients with systemic lupus erythematosus without neuropsychiatric symptoms

OBJECTIVE

To study the functional brain activation signals before and after sufficient disease control in patients with systemic lupus erythematosus (SLE) without clinical neuropsychiatric symptoms.

METHODS

Blood-oxygen-level-dependent signals during event-related functional magnetic resonance imaging brain were recorded, while 14 new-onset SLE patients and 14 demographically and intelligence quotient matched healthy controls performed the computer-based Wisconsin card sorting test for assessing executive function, which probes strategic planning and goal-directed task performance during feedback evaluation (FE) and response selection (RS), respectively. Composite beta maps were constructed by a general linear model to identify regions of cortical activation. Blood-oxygen-level-dependent functional magnetic resonance imaging signals were compared between (1) new-onset SLE patients and healthy controls and (2) SLE patients before and after sufficient control of their disease activity.

RESULTS

During RS, SLE patients demonstrated significantly higher activation than healthy controls in both caudate bodies and Brodmann area (BA) 9 to enhance event anticipation, attention, and working memory, respectively, to compensate for the reduced activation during FE in BA6, 13, 24, and 32, which serve complex motor planning and decision-making, sensory integration, error detection, and conflict processing, respectively. Despite significant reduction of SLE activity, BA32 was activated during RS to compensate for reduced activation during FE in BA6, 9, 37, and 23/32, which serve motor planning, response inhibition and attention, color processing and word recognition, error detection, and conflict evaluation, respectively.

CONCLUSIONS

Even without clinically overt neuropsychiatric symptoms, SLE patients recruited additional pathways to execute goal-directed tasks to compensate for their reduced strategic planning skill despite clinically sufficient disease control.
