Psoriatic arthritis and depressive symptoms: does systemic inflammation play a role?

Interleukin levels and depressive symptoms in psoriatic arthritis patients: insights from a case-control study on socio-demographic factors and disease perception

In the course of psoriatic arthritis (PsA), depression occurs much more often than in the general population. Depression can be considered a poor prognostic factor. The aim of the study was to assess the relationships between the occurrence of depression and the levels of proinflammatory cytokines in patients with PsA. The study included 86 (47F/39M) patients with PsA. Only patients with high disease activity (DAPSA > 28) were enrolled in the study. The severity of depressive symptoms was assessed using the Beck Depression Inventory II (BDI-II) for all patients. Additionally, sociodemographic data were collected. All patients were also assessed for the levels of interleukins (IL): IL-1, IL-6, IL-17A, IL-23, and tumor necrosis factor alpha (TNF-α) using the enzyme-linked immunosorbent assay (ELISA) test. In the study group, depression (BDI-II ≥ 14) was diagnosed in 45 patients (52%). Patients with coexisting depression reported higher levels of pain and disease activity on the visual analogue scale compared to patients without depression (8.5 vs. 7.7, p < 0.001 and 9.3 vs. 8.4, p < 0.001, respectively). The mean levels of proinflammatory cytokines [pg/ml], IL-1 and IL-6, were also higher in the group of patients with depression (46.4 vs. 4.7, p < 0.001 and 10.5 vs. 4.9, p < 0.001, respectively). The coexistence of depression in the course of Psoriatic Arthritis (PsA) is associated with higher levels of IL-1 and IL-6. Depression has a negative impact on the perception of the underlying disease and is linked to reduced social and occupational activity.

Depressive symptoms are associated with fatigue, poorer functional status and less engagement in sports in axSpA and PsA: an analysis from the RABBIT-SpA cohort

BACKGROUND

In patients with axial spondyloarthritis (axSpA) or psoriatic arthritis (PsA), concomitant depression might have a negative impact on the course of disease and treatment outcomes. The aims of this analysis are to determine the prevalence of depressive symptoms in axSpA and PsA patients in a real-world cohort study and to identify sociodemographic and clinical associated factors for moderate or severe depressive symptoms in both diseases.

METHODS

Patients from the RABBIT-SpA cohort with an axSpA or PsA diagnosis and a valid WHO-5 Well-Being Index score at baseline were included. A descriptive analysis of baseline and outcome parameters by category of depressive symptoms was performed and factors associated with the presence of depressive symptoms (moderate or severe) were examined in a logistic regression.

RESULTS

Two thousand four hundred seventy patients (1,245 axSpA; 1,225 PsA) were included in the analysis. In both diagnoses, the proportion of patients with moderate depressive symptoms was 8% and 21% with severe symptoms. Patients with moderate or severe depressive symptoms were less likely to engage in sports than those with no or mild depressive symptoms, had more comorbidities and higher scores for disease activity, functional limitations, fatigue, and pain and took more analgesics. In axSpA, patients with a higher disease activity, a greater functional impairment and more severe fatigue were more likely to experience depressive symptoms, while patients with more years in education and engaging in sports for at least 1 h/week were less likely to experience depressive symptoms. PsA patients with a greater functional impairment and more severe fatigue were more likely to experience depressive symptoms while those engaging in sports for at least 1 h/week were less likely to experience depressive symptoms.

CONCLUSION

We confirmed a high prevalence of depressive symptoms in both PsA and axSpA. Factors negatively associated with the presence of depressive symptoms were fatigue, not engaging in sports, and greater functional limitations. Depressive symptoms may affect the perception of disease activity / severity by patients. Thus, depressive symptoms are an important condition in axSpA and PsA that should be considered when evaluating disease activity and treatment outcomes.

Epidemiology of mental health comorbidity in patients with psoriasis: An analysis of trends from 1986 to 2019

BACKGROUND

The prevalence of mental disorders such as depression, anxiety, and suicide has increased in patients with psoriasis, although no study has systematically analyzed the epidemiology worldwide.

OBJECTIVE

To explore the prevalence and incidence of psoriasis with comorbid mental disorders (i.e., depression, anxiety, and suicide).

METHODS

Five databases from establishment through May 2022 were searched. Stata SE 15.1 was used for the data analysis. Subgroup, meta-regression, and sensitivity analyses were used to evaluate the heterogeneity of pooled studies.

RESULTS

We evaluated 56 studies in our research. The prevalence of depression, anxiety, and suicide in adults with psoriasis was 20%, 21%, and 0.77%. Patients with psoriasis in North America had a higher prevalence of depression and suicide, whereas those in South America had a higher prevalence of anxiety. The incidence of depression, anxiety, and suicide was 42.1, 24.7, and 2.6 per 1000 person-years in adults with psoriasis, respectively.

LIMITATIONS

All of the included studies were published in Chinese and English, causing a degree of selection bias.

CONCLUSION

These findings demonstrate the incidence and prevalence of comorbid mental disorders in patients with psoriasis, which may raise awareness among physicians and patients regarding the mental problems associated with psoriasis.

Serum interleukin-23 levels: relation to depression, anxiety, and disease activity in psoriatic arthritis patients

Objectives

Assessment of serum levels of IL-23 in PsA patients and its correlation with depression, anxiety, and disease activity.

Methods

Eighty psoriatic arthritis (PsA) patients and eighty healthy volunteers matched for age and gender were included in this observational case–control study. All participants suspected to detailed history, clinical assessment, PsA activity using Disease Activity Index for Psoriatic Arthritis (DAPSA) score, the severity and extent of psoriasis was assessed by the Psoriasis Area and Severity Index (PASI), and ultrasonographic assessments of the entheses were examined according to the Madrid Sonographic Enthesitis Index (MASEI). Depression and anxiety were assessed by Hospital Anxiety and Depression Scale (HADS). Serum IL-23 was measured and correlated with disease activity, depression, and anxiety.

Results

There was no significant difference between patients and controls regarding demographic data. Thirty-six PsA patients (45%) had anxiety and 28 patients (35%) had depression, while in the control group, 16 persons (20%) had anxiety and 12 (15%) had depression, with significant differences between the 2 groups (p < 0.0001). There were significant differences in HADS anxiety and depression scores between patients and controls with significant positive correlations between HADS depression, anxiety scores and IL-23, DAPSA, PASI, and MASEI scores (p < 0.05). IL-23 was positively correlated with DAPSA, PASI, and HADS scores; we observed that interleukin 23, higher DAPSA, and PASI were independently associated with depression and anxiety.

Conclusion

Serum interleukin-23 levels were elevated in PsA patients and were found to be correlated with depression, anxiety, and disease activity.

Key Points • Psoriatic arthritis is a multidimensional disorder with psychiatric drawbacks. • Interleukin-23 is a proinflammatory cytokines that was correlated with depression and anxiety in PsA patients. • Interleukin-23 was correlated with disease activity in PsA. • Depression and anxiety were positively correlated with disease activity in PsA.

Depression in psoriatic arthritis: Related to socio-demographics, comorbid loads or disease activity?

AIM

Psychological distress commonly occurs in patients with psoriatic arthritis (PsA). The primary objective of this study was to determine the prevalence of depression in PsA. The secondary objective was to explore its associated factors, including socio-demographics, disease activity data and comorbidities.

METHODS

Patients with PsA fulfilling the Classification Criteria for Psoriatic Arthritis were consecutively recruited from local rheumatology clinics. Depression was assessed by a self-administered Chinese-Cantonese version of the Hospital Anxiety and Depression Scale (HADS).

RESULTS

Two hundred and eight eligible patients with PsA were recruited, with 82 females and 126 males. Depression was found in 62 (29.8%) of them. The univariate model identified these associated factors: (1) Psoriasis Area and Severity Index score; (2) disease activity measurement, that is tender and swollen joint count, erythrocyte sedimentation rate, C-reactive protein, Disease Activity in Psoriatic Arthritis (DAPSA) score, Leeds Enthesitis Index and tender dactylitis count; (3) quality of life measurement, that is Health Assessment Questionnaire - Disability Index (HAQ-DI), pain and general health perception; (4) PsA duration; and (5) body mass index. The final regression model identified DAPSA and HAQ-DI were closely associated with depression, P = .007 and P = .02 respectively. Moderate and strong correlations with HADS score were found with DAPSA (Kendall's tau-b coefficient [τb] = 0.25) and HAQ-DI (τb = 0.4) respectively. No associations with depression were found between age, living and employment status, gender, demographics, inflammatory markers, disease duration, skin involvement and comorbidities, in term of Charlson's Comorbidity Index.

CONCLUSION

Depression was prevalent among PsA patients and it was closely correlated with disease activity and physical function impairment. Achieving low disease activity and maintaining physical function in patients with PsA may mitigate the psychological burden. The present study also highlighted the unmet needs of strategies to identify this common phenomenon.

Depression and Endothelial Dysfunction in Psoriatic Arthritis: Is There Any Possible Relationship?

Background: Cardiovascular events (CVEs) are the first cause of death in patients with psoriatic arthritis (PsA). Depression is a recognized risk factor in cardiovascular events and is frequently associated with PsA. Flow-mediated dilatation (FMD) is a widely used method for assessing endothelial dysfunction, a parameter with strong prognostic implications for CVEs. The study aims to explore the relationship between FMD, depressive symptoms and serum cytokines in a cohort of patients with PsA. Patients and Methods: FMD was assessed in 50 consecutive PsA patients aged between 30 and 75 years without known cerebrovascular and coronary heart disease or diabetes. Depressive symptoms were reported using the related subscale of the Hospital Anxiety and Depression Scale (HDS). Disease features, activity indexes, and adjusted Framingham risk score (aFRS) were calculated. Serum level of IL-6, TNF-α, and IL-17A were also assessed. Results: In PsA patients (age 50.7 ± 10.2 years, male 42%, disease duration 5.9 ± 3.3 years, Disease Activity in PSoriatic Arthritis (DAPSA) score 14.0 ± 9.4) FMD inversely correlated with the severity of depressive symptoms according to HDS (ρ = -0.339, p = 0.016), age (ρ = -0.507, p = 0.001), aFRS (rs = -0.453, p < 0.001), duration of PsA (ρ = -0.507, p = 0.001), intensity of pain (ρ = -0.507, p = 0.001), and DAPSA (ρ = -0.507, p = 0.001). No statistically significant correlation was found between FMD or HDS and serum cytokines concentrations. HDS predicted FMD in a model adjusted for age, aFRS, PsA duration, and pain intensity (β = -0.271, p = 0.008), with depressive symptoms contributing directly to 6.4% of the variance. Conclusions: Depressive symptoms correlate with endothelial dysfunction with an exposure-response pattern in our cohort of PsA patients.
