Prevalence and severity of depression and anxiety in patients with systemic lupus erythematosus: An epidemiologic study in Iranian patients

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.

Association of DYNC1H1 gene SNP/CNV with disease susceptibility, GCs efficacy, HRQOL, anxiety, and depression in Chinese SLE patients

Background

Systemic lupus erythematosus is a heterogeneous autoimmune disease characterized by multi‐system injuries and overproduction of autoantibodies. There are many genetic studies on SLE, but no report has considered the relationship between cytoplasmic dynein and SLE susceptibility.

Objectives

Our study intends to investigate whether DYNC1H1 gene SNP/CNV is related to SLE susceptibility, GCs efficacy, HRQOL, anxiety, and depression in Chinese SLE patients.

Methods

A total of 502 cases and 544 healthy controls were recruited into the case‐control study, and 472 subjects from the case group were followed up for 12 weeks to evaluate GCs efficacy, HRQOL, anxiety, and depression. Multiplex SNaPshot technique was applied to genotype the seven SNPs of DYNC1H1, and AccuCopy^TM method was conducted to quantify the copy number of DYNC1H1. Anxiety and depression were evaluated using HAMA and HAMD‐24 scales, respectively. The SF‐36 scale was used to assess HRQOL.

Results

The significant association between SNP rs1190606 and SLE susceptibility was displayed in the dominant model (P_BH = 0.004) as well as its allele model (P_BH = 0.004). We also found that SNP rs2273440 was related to photosensitization symptom in SLE patients (P_BH = 0.032). In the follow‐up study, SNP rs11160668 was connected with the improvement of BP in male patients (P_BH = 0.011). However, no association of DYNC1H1 gene with GCs efficacy, anxiety, and depression was found. No CNV in DYNC1H1 was detected.

Conclusions

The study suggests that DYNC1H1 gene polymorphisms may have an effect on SLE susceptibility and BP improvement of HRQOL in Chinese SLE patients.

Major depressive disorders accompanying autoimmune diseases - Response to treatment

MDDs (major depressive disorders) belong to the most frequently diagnosed mental diseases and affect approximately 350 million people all over the world. A growing body of evidence suggests that inflammatory processes may play a significant role in the pathophysiology and progression of the disease. The comorbidity of MDDs with many other medical conditions, for example autoimmune diseases (ADs) caused by inflammation, has been observed on numerous occasions. In both cases, increased levels of pro-inflammatory cytokines, chemokines and other inflammatory agents are observed. Furthermore, higher rates of inflammatory markers are associated with a poorer response to antidepressant treatment. Additionally, the presence of any AD is associated with higher prevalence of depression and may reduce the chance of effective therapy. Interestingly, the administration of several anti-inflammatory agents used in AD treatment is positively correlated with a reduction of depressive symptoms. In conclusion, the factors contributing to the coexistence of depression as well as affecting antidepressant treatment effectiveness may lead to an alteration of the cytokine profiles in many autoimmune diseases.

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.

Cytokine Levels in Panic Disorder: Evidence for a Dose-Response Relationship

OBJECTIVE

Several studies have investigated possible biological correlates of mental disorders. Although some studies have consistently reported elevated levels of serum inflammatory markers in depression, very few have evaluated cytokine levels in patients with lifetime panic disorder (PD).

METHODS

Seventy-eight adults (75% women) from an anxiety disorders outpatient unit were categorized according to their PD status: current or in remission. Serum levels of interleukin (IL)-6, tumor necrosis factor α, and IL-10 were evaluated using flow cytometry with enhanced sensitivity flex sets. Data on clinical comorbidity, lipid profile, fasting blood glucose, C-reactive protein, and PD severity were also obtained.

RESULTS

Significantly higher mean levels of serum IL-6 (0.83 vs 0.60 pg/mL [95% confidence interval {CI}for the log-transformed mean difference, -0.41 to -0.57], p = .008) but not of tumor necrosis factor-α (0.18 vs 0.14 pg/mL [95% CI, -1.12 to 0.11]; p = 0.53) or IL-10 (0.21 vs 0.26 [95% CI, -0.20 to 0.44]; p = 0.16), were associated with current PD compared to remitted PD. Higher Panic Disorder Severity Scale (standardized β = 0.36; p = .013), body mass index (standardized β = 0.53, p < .001) and fasting blood glucose 5.6 mmol/L or greater (standardized β = 0.23, p = .038) were significantly associated with higher levels of IL-6 in the multivariate linear regression model.

CONCLUSIONS

Our findings support a proinflammatory state in patients with current PD that is independent of possible confounders. Although there are important implications of these findings, replication is required.

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.

Depression, Anxiety and Disease-Related Variables and Quality of Life Among Individuals With Systemic Lupus Erythematosus Living in Kermanshah Province, Iran

BACKGROUND

Health-related quality of life (HRQoL) is affected by numerous variables including depression and anxiety. However, these associations have not yet been described among patients with systemic lupus erythematosus (SLE) and the impact of SLE-related clinical variables remains unknown.

OBJECTIVES

In this cross-sectional study, the prevalence of depression and anxiety among Iranian patients with SLE living in Kermanshah province, Iran, has been estimated and the determinants of HRQoL in comparison with healthy subjects have been identified.

PATIENTS AND METHODS

Sampling was performed based on recruitment of subjects according to inclusion and exclusion criteria. Systemic lupus erythematosus-related variables including cutaneous manifestations, pericarditis, arthritis, history of seizure and psychosis were recorded. Blood samples were taken to measure antinuclear antibodies (ANA), anti-double stranded DNA (anti-dsDNA), Anti-Smith (Anti-SM), anticardiolipin antibody. Matched healthy subjects in demographic characteristics were selected from general population of Kermanshah province, Iran. Depression and anxiety and HRQoL were assessed using the Beck depression inventory-II, Beck anxiety inventory and short-form 36 health survey, respectively.

RESULTS

A total of 310 individuals (160 patients with SLE and 150 healthy subjects) participated in this study. The prevalence of depression and anxiety was about 20% among people with SLE, which was noticeably high but not significantly different from healthy individuals. More severe depression was associated with lower scores in domains of physical functioning (PF), role limitation due to physical problems (RP) and subsequently physical component summary (PCS) in the SLE group (P < 0.0001 for all). A higher anxiety level was negatively correlated with PF, RP, social functioning (SF), general health (GH) and PCS in the SLE group (P = 0.01, < 0.0001, 0.004, 0.02 and 0.005, respectively). Scores of PF and PCS were significantly lower among patients with SLE compared to the control group (P = 0.001 for both). Malar rash, photosensitivity, discoid rash, pleuritis, pericarditis, history of seizure and positive Anti-SM Ab were associated with poorer SF (P = 0.003, 0.003, 0.018, 0.001, < 0.0001, 0.021 and 0.002, respectively).

CONCLUSIONS

The results of this study show that patients with SLE have poorer HRQoL in physical components whereas the mental component of QoL is relatively similar to healthy individuals. Depression and anxiety were not related to clinical manifestations of SLE. However, the SF domain of HRQoL was the most susceptible component of QoL, which was affected by SLE clinical variables. The high estimated prevalence of depression and anxiety among patients with SLE requires attention.

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.
