Physical pain and suicide-related outcomes across the lifespan: systematic review and meta-analysis

Suicide is a complex and multifactorial phenomenon, with increasing evidence highlighting the link between physical pain and suicidal thoughts and behaviors. This meta-analysis examines suicide-related outcomes among individuals with and without physical pain. We searched PubMed, PsycINFO, and Cochrane databases, including 91 studies in the review and 88 in the meta-analysis. Data were analyzed using Comprehensive Meta-Analysis software (version 3.7). The findings revealed that people experiencing physical pain were significantly more likely to have suicide-related outcomes than those without pain. The strongest associations were found for lifetime death wish (OR = 2.10), current suicidal ideation (OR = 1.93), and lifetime suicide attempts (OR = 1.94). Among adolescents, self-harm was notably higher among those with pain, while adults showed a higher risk of lifetime suicide attempts and suicide death. In older adults, suicidal ideation and suicide attempts were more strongly linked to pain. Females had higher odds of suicidal ideation compared to males. Specific painful conditions, like fibromyalgia, abdominal pain, and migraines, were also linked to increased suicide risk. Limitations include high heterogeneity and lack of data on some suicide-related outcomes. Pain is a significant risk factor for suicidality across all ages and in specific populations, as conceptualized by ideation-to-action framework suicide models.

Illustrating Emerging Good Practices for Quantitative Benefit-Risk Assessment: A Hypothetical Case Study of Systemic Biologic Treatments for Plaque Psoriasis

OBJECTIVES

Quantitative benefit-risk assessment (qBRA) is a structured process to evaluate the benefit-risk balance of treatment options to support decision making. The ISPOR qBRA Task Force was recently established to provide recommendations for the design, conduct, and reporting of qBRA. This report presents a hypothetical case study illustrating how to apply the Task Force's recommendations toward a qBRA to inform the benefit-risk assessment of brodalumab at the time of initial marketing approval. The qBRA evaluated 2 dosing regimens of brodalumab (210 mg or 140 mg twice weekly) compared with weight-based dosing of ustekinumab and placebo.

METHODS

We followed the 5 steps recommended by the Task Force. Attributes included treatment response (≥75% improvement in Psoriasis Area and Severity Index), suicidal ideation and behavior, and infections. Performance data were drawn from pivotal clinical trials of brodalumab. The qBRA used multicriteria decision analysis and preference weights from a hypothetical discrete choice experiment. Sensitivity analyses examined the robustness of benefit-risk ranking to uncertainty in clinical effect and preference estimates, consideration of a subgroup (nail psoriasis), and the maintenance phase of treatment (52 weeks instead of 12).

RESULTS

Results from this hypothetical qBRA suggest that brodalumab 210 mg had a more favorable benefit-risk profile compared with ustekinumab and placebo. Ranking of brodalumab compared with ustekinumab was dependent on brodalumab's dose. Sensitivity analyses demonstrated robustness of benefit-risk ranking to uncertainty in clinical effect and preference estimates, as well as choice of attributes and length of follow-up.

CONCLUSION

This case study demonstrates how to implement the ISPOR Task Force's good practice recommendations on qBRA.

Long-Term Health-Related Quality of Life in Patients with Plaque Psoriasis Treated with Certolizumab Pegol: Three-Year Results from Two Randomised Phase 3 Studies (CIMPASI-1 and CIMPASI-2)

INTRODUCTION

Certolizumab pegol (CZP) is an Fc-free, PEGylated, anti-tumour necrosis factor biologic. Safety and efficacy data for CZP over 3 years have been previously reported. We report 3-year quality of life (QoL) outcomes for patients treated with CZP, pooled from two phase 3 trials.

METHODS

Adults with moderate-to-severe plaque psoriasis for ≥ 6 months were initially randomised 1:2:2 to double-blinded placebo every 2 weeks (Q2W), CZP 200 mg Q2W (loading dose of CZP 400 mg at weeks 0/2/4) or CZP 400 mg Q2W. All patients received open-label CZP (200 mg or 400 mg Q2W) from week 48. Dermatology Life Quality Index (DLQI), 36-Item Short Form Survey (SF-36), EuroQol 5-Dimensions 3-Level (EQ-5D-3L) and Work Productivity and Activity Impairment (WPAI) scores are reported as observed.

RESULTS

At week 0, 100 patients were randomised to placebo, 186 to CZP 200 mg Q2W and 175 to CZP 400 mg Q2W. For CZP-randomised patients, 60.9% had a DLQI score of 0 or 1 by week 48. Both the physical and mental component scores of SF-36 also improved from baseline to week 48 (mean change from baseline: 4.4 and 5.4, respectively). The proportion of patients with a score of 1 in the EQ-5D-3L Pain/Discomfort dimension increased (week 0, 21.1%; week 48, 66.2%), and WPAI Presenteeism, Work Impairment, and Activity Impairment improved from baseline to week 48, with the strongest gains observed for Activity Impairment (week 0, 33.3% of time impaired; week 48, 6.7%). Across patient-reported outcomes, gains were sustained through week 144, with durable improvements observed regardless of sex, psoriatic arthritis status or prior exposure to biologics.

CONCLUSION

CZP treatment was associated with sustained and tangible improvements in health-related QoL (DLQI and SF-36), health status (EQ-5D-3L) and functional impairment at work and in other daily activities (WPAI).

Trajectories of systemic agent use and associated depression- and anxiety-related health care costs among patients with psoriasis

Background

Systemic treatment patterns and related mental health disorders and economic burden among patients with psoriasis are largely unknown.

Objective

To assess systemic treatment patterns and associated depression and anxiety-related health care costs among patients with psoriasis initiating a conventional systemic treatment (CST).

Methods

Using a retrospective cohort design with sequence and cluster analyses, we assessed systemic treatment trajectories (CST and tumor necrosis factor inhibitors or ustekinumab, [TNFi/UST]) over a 2-year period following CST initiation. We compared health care costs between trajectories using 2-part models.

Results

We included 781 patients and identified 8 trajectories: persistent methotrexate users, persistent acitretin users, early CST discontinuation, late methotrexate discontinuation, switch to TNFi/UST, adding TNFi/UST, discontinuation then restart on methotrexate, and discontinuation then restart on acitretin or multiple CST switches. Overall, 165 (21%) patients incurred depression- and anxiety-related health care costs (median annual cost, CAN$56; quartiles, $14-$127). Compared with persistent methotrexate users, adding a TNFi/UST (cost ratio, 3.63; 95% CI, 1.47-5.97) and discontinuation then restart on acitretin or multiple switches between systemic agents (cost ratio, 13.3; 95% CI 5.76-22.47) had higher costs.

Limitations

Trajectory misclassification may have occured. These date represent an association, and causality cannot be inferred, particularly given the risk of confounding.

Conclusion

Depression- and anxiety-related health care costs were high among patients adding TNFi/UST and those discontinuing then restarting on acitretin or experiencing multiple switches between systemic agents.

HautTief Multidisciplinary Educational Program for Patients with Psoriasis or Atopic Dermatitis: A Randomized Controlled Study

Background

Improving health-related quality of life (HRQoL), disease severity, and treatment adherence through patient education is an increasingly important, yet relatively new area in dermatology. This randomized controlled trial aims to contribute to this growing area of research by exploring the effects of a 9-week educational program for patients with chronic skin diseases.

Objective

The aim of the study was to evaluate the effect of a multidisciplinary educational program on HRQoL and disease severity in patients with psoriasis or atopic dermatitis (AD).

Methods

Sixty-four patients with diagnosed psoriasis or AD were recruited from University Hospital Zurich and randomized (1:1) to the intervention or control group. To assess HRQoL, the following self-reported questionnaires were used: Dermatology Life Quality Index (DLQI), Skindex-29, EuroQol-5D (EQ-5D), RAND 36-Item Short Form Survey (SF-36), and Beck Depression Inventory (BDI) to measure depression symptoms. Psoriasis Area and Severity Index (PASI) and the Eczema Area and Severity Index (EASI) were used to capture disease extent. These scores were assessed at four study visits, which were performed at baseline and 3, 6, and 9 months after the start of the program.

Results

At month 6, an improvement of at least 25% in BDI was recorded in 15 (68.2%) of 22 patients in the intervention group and 6 (27.3%) of 22 patients in the control group (difference 40.9%, p = 0.016). 53.3% (16 of 30) of patients achieved an improvement in one subdomain of the SF-36 score (role limitations due to emotional problems) at 6-month follow-up, compared with 23.1% (6 of 26) of those not attending the educational program (difference 30.2%; p = 0.042). No significant differences in DLQI, Skindex-29, EQ-5D, PASI, and EASI between both groups at the three time points were found.

Conclusion

An educational program may improve HRQoL and depression status of patients with psoriasis or AD.

Sex Differences in the Patterns of Systemic Agent use Among Patients With Psoriasis: A Retrospective Cohort Study in Quebec, Canada

Background: Sex differences exist in psoriasis manifestation and expectations from treatment with systemic agents, including, conventional systemic agents (CSA) and tumor necrosis factor inhibitors or ustekinumab (TNFi/UST). However, sex differences in patterns of systemic agent use, such as CSA discontinuation and switch from CSA to TNFi/UST have not been examined.

Objectives: To assess sex differences in patterns of CSA use and identify factors associated with switch to (or add) a TNFi/UST and those associated with CSA discontinuation.

Methods: We conducted a retrospective cohort study using the Quebec health administrative databases. We included patients with psoriasis initiating a CSA in 2002–2015. We excluded patients with a psoriasis diagnosis in the 3 years prior to the first diagnosis date between 2002 and 2015, and those with a systemic agent dispensation in the year prior to that date. We used Cox regression models with the Least Absolute Shrinkage and Selection Operator method to identify factors associated with Switch/add TNFi/UST, and those associated with CSA discontinuation. Separate analyses were performed for male and female patients.

Results: We included 1,644 patients (55.7% females, mean age 60.3 years), among whom 60.4% discontinued their CSA and 7.4%, switched/added TNFi/UST (3.4% switched and 4.0% added) within a median of 0.78 years of follow-up. Among male and female patients, rates of Switch/add TNFi/UST per 1,000 person-year were 49.1 and 41.0 and rates of CSA discontinuation were 381.2 and 352.8. Clinical obesity in male patients (HR 3.53, 95% CI 1.20–10.35), and adjustment/somatoform/dissociative disorders (HR 3.17, 95% CI 1.28–7.85) and use of nonsteroidal anti-inflammatory drugs (HR 2.70, 95% CI 1.56–4.70) in female patients were associated with Switch/add TNFi/UST. Male patients followed by a rheumatologist (HR 0.66, 95% CI 0.46–0.94) and those with a prior hospitalization (HR 0.70, 95% CI 0.57–0.87) were at lower risk of CSA discontinuation, while those initiated on acitretin (vs methotrexate) were at higher risk to discontinue their CSA (HR 1.61, 95% CI 1.30–2.01). Female patients with rheumatoid arthritis comorbidity (HR 0.69, 95% CI 0.51–0.93), those with a dispensed lipid-lowering agent (HR 0.72, 95% CI 0.59–0.88) and hypoglycemic agent (HR 0.75, 95% CI 0.57–0.98) and those initiated on methotrexate (vs all other CSAs) were less likely to discontinue their CSA. Male and female patients entering the cohort between 2011 and 2015 were at reduced risk of CSA discontinuation compared to those entering the cohort before 2011.

Conclusion: Most male and female patients discontinued their CSA within 1 year of follow-up. Our study highlighted sex differences in patients’ characteristics associated with switch/add a TNFi/UST and CSA discontinuation; treatment switch and discontinuation may be indications of treatment failure in most patients.

Long non-coding RNA RP11-342L8.2, derived from RNA sequencing and validated via RT-qPCR, is upregulated and correlates with disease severity in psoriasis patients

OBJECTIVE

This study aimed to explore the dysregulated long non-coding RNA (lncRNA) expression profile in psoriatic tissue vs. normal skin tissue via RNA sequencing (RNA-seq), then further sort candidate lncRNAs to be validated by reverse transcription quantitative polymerase chain reaction (RT-qPCR), in order to investigate the comprehensive linkage of lncRNA with psoriasis.

METHODS

Twenty-five psoriasis patients were consecutively enrolled, with their psoriatic and surrounding normal skin tissues obtained. Ten pairs of psoriatic and normal tissues were proposed to RNA-seq. Then, top 6 differentially expressed lncRNAs (DElncRNA) were sorted as candidate lncRNAs for validation by RT-qPCR in 25 pairs of samples.

RESULTS

Principal component analysis (PCA) exhibited that lncRNA profile clearly distinguished psoriatic tissue from normal tissue, so did heatmap. Volcano plot disclosed 412 upregulated and 625 downregulated DElncRNAs in psoriatic tissue vs. normal tissue. Gene Ontology (GO) and Kyoko Encyclopedia of Genes and Genomes (KEGG) enrichment analyses exhibited that these DElncRNAs were mainly enriched in immune, inflammation, or proliferation-related biological processes and pathways such as neutrophil degranulation, regulation of immune response, positive regulation of cell proliferation, and MAPK signaling pathway. By RT-qPCR validation, lncRNAs RP11-22A3.2, RP11-342L8.2, and CTD-2006H14.2 were increased (all P < 0.001), while lncRNAs AP000442.4, CCDC144NL-AS1, and MIR663AHG were decreased (all P < 0.01) in psoriatic tissue vs. normal tissue. Interestingly, psoriatic lncRNA RP11-342L8.2 was also observed to positively correlated with psoriasis area and severity index (PASI) (r = 0.405, P = 0.045).

CONCLUSION

Our present study exhibits some evidence for the landscape of lncRNAs implicated in psoriasis.

Quality of life and patient-perceived symptoms in patients with psoriasis undergoing proactive or reactive management with the fixed-dose combination Cal/BD foam: A post-hoc analysis of PSO-LONG

Background

Psoriasis has important physical and psychosocial effects that extend beyond the skin. Understanding the impact of treatment on health‐related quality of life (HRQoL) and patient‐perceived symptom severity in psoriasis is key to clinical decision‐making.

Objectives

This post hoc analysis of the PSO‐LONG trial data assessed the impact of long‐term proactive or reactive management with fixed‐dose combination calcipotriene 50 µg/g and betamethasone dipropionate 0.5 mg/g (Cal/BD) foam on patient‐reported outcomes (PROs) in patients with psoriasis vulgaris.

Methods

Five hundred and twenty‐one patients from the Phase 3, randomized, double‐blind PSO‐LONG trial were included. An initial 4‐week, open‐label phase of fixed‐dose combination Cal/BD foam once daily (QD) was followed by a 52‐week maintenance phase, at the start of which patients were randomized to a proactive management arm (Cal/BD foam twice weekly) or reactive management arm (vehicle foam twice weekly). Patient‐perceived symptom severity and HRQoL were assessed using the Psoriasis Symptom Inventory (PSI), the Dermatology Life Quality Index (DLQI) and the EuroQol‐5D for psoriasis (EQ‐5D‐5L‐PSO).

Results

Statistically and clinically significant improvements were observed across all PRO measures. The mean difference (standard deviation) from baseline to Week 4 was −8.97 (6.18) for PSI, −6.02 (5.46) for DLQI and 0.11 (0.15) for EQ‐5D‐5L‐PSO scores. During maintenance, patients receiving reactive management had significantly higher DLQI (15% [p = 0.007]) and PSI (15% [p = 0.0128]) and a numerically lower EQ‐5D‐5L‐PSO mean area under the curve score than patients receiving proactive management (1% [p = 0.0842]).

Conclusions

Cal/BD foam significantly improved DLQI, EQ‐5D‐5L‐PSO and PSI scores during the open‐label and maintenance phases. Patients assigned to proactive management had significantly better DLQI and PSI scores and numerically better EQ‐5D‐5L‐PSO versus reactive management. Additionally, baseline flare was associated with worse PROs than the start of a relapse, and patients starting a relapse also had worse PROs than patients in remission.

Risk for Suicidal Behavior Among Psoriasis Patients: A Nationwide Cohort Study

BACKGROUND

The link between psoriasis and suicidality remains elusive and understudied.

OBJECTIVE

The aim was to assess the risk of suicidal behavior in psoriasis patients.

METHODS

We used Taiwan's National Health Insurance Research Database to conduct a nationwide retrospective cohort study to examine the risk for suicidal behavior among psoriasis patients. We performed subgroup analyses based on the severity of psoriasis and psoriatic arthritis.

RESULTS

We included 169,909 psoriasis patients (including 13,959 with concomitant psoriatic arthritis and 155,950 with psoriasis alone) and 169,909 matched nonpsoriasis controls. Suicidal behavior occurred in 104 and 89 subjects in the psoriasis group and nonpsoriasis controls, respectively; we found no significantly increased risk for suicidal behavior among psoriasis patients when compared to nonpsoriasis controls [adjusted hazard ratio (HR) 1.17, 95% confidence interval (CI) 0.88‒1.55]. The subgroup analysis showed no significantly increased risk for suicidal behavior in both the severe psoriasis group (adjusted HR 0.92, 95% CI 0.51-1.64) and the mild psoriasis group (adjusted HR 1.26, 95% CI 0.91‒1.75) when compared to nonpsoriasis controls. Also, we found no significant increased risk for suicidal behavior in the group of psoriasis patients who also had psoriatic arthritis (adjusted HR 2.00, 95% CI 0.68‒5.85) and in the group of patients with psoriasis alone (adjusted HR 1.12, 95% CI 0.83‒1.50) when compared to nonpsoriasis controls.

CONCLUSION

In a Taiwanese setting, no link between psoriasis or psoriatic arthritis and suicidal behavior was detected.

Psoriasis and suicidality: A review of the literature

Psoriasis is a chronic systemic inflammatory skin disease, which has been associated with an increased risk of numerous medical and psychiatric comorbidities, including suicidality. Suicidality, which can be divided into the categories of suicidal ideation, suicide attempt, and completed suicide, is highly prevalent in the psoriasis population, and multiple studies have been published on the subject of psoriasis and suicidal ideation and behavior (SIB), including two recent meta-analyses. However, the available literature is limited and inconsistent, and the association between the two remains incompletely understood. The present review aims to cohesively synthesize and summarize the available evidence, while making a clinically relevant distinction between the sub-categories of suicidality, by examining not only the epidemiology of the association but also the plausible molecular mechanisms and the potential influence of biologic therapies. Additionally, this review aims to critically examine and understand the potential contribution of depression in the psoriasis and suicidality relationship. This will allow us to better understand the complex and multi-faceted relationship between psoriasis and suicidality, to identify those who may be most at risk for SIB, to make evidence-based clinical decisions regarding treatment and management, and to more completely address the needs of psoriasis patients.

Anxiety and depression in patients with moderate-to-severe psoriasis and comparison of change from baseline after treatment with guselkumab vs. adalimumab: results from the Phase 3 VOYAGE 2 study

BACKGROUND

Anxiety and depression are clinically significant comorbidities associated with psoriasis. Improvements in psoriasis are known to decrease anxiety and depression. Guselkumab, an anti-interleukin-23 monoclonal antibody, has demonstrated efficacy and safety for the treatment of moderate-to-severe psoriasis.

OBJECTIVE

Assess improvements in anxiety and depression with guselkumab vs. placebo and adalimumab using the Hospital Anxiety and Depression Scale (HADS).

METHODS

In VOYAGE 2, a Phase 3, randomized, double-blind, placebo- and adalimumab-controlled study, patients received placebo (through week 16 followed by crossover to guselkumab), guselkumab, or adalimumab through week 24. HADS consists of two subscales measuring anxiety (HADS-A) and depression (HADS-D), with scores ranging from 0 to 21 and higher scores indicating more severe symptoms. Scores ≥8 indicate instrument-defined anxiety or depression. Severity of psoriasis was assessed using the Psoriasis Area and Severity Index (PASI).

RESULTS

Among 989 patients randomized (with baseline HADS measurements), mean HADS-A and HADS-D scores were 6.8 ± 4.2 and 5.3 ± 4.2, respectively; 38.6% of patients reported HADS-A ≥8 and 27.7% HADS-D ≥8 at baseline. At week 16, a significantly greater proportion of guselkumab patients with baseline HADS-A or HADS-D ≥8 reported HADS-A <8 (51.4% vs. 25.9%; P < 0.001) or HADS-D <8 (59.2% vs. 27.0%; P < 0.001) vs. placebo patients. At week 24, a greater proportion of guselkumab patients with baseline HADS-A or HADS-D ≥8 reported HADS-A <8 (58.4% vs. 42.9%; P = 0.028) or HADS-D <8 (59.8% vs. 46.4%; P = 0.079) vs. adalimumab patients. PASI improvements correlated with improvement in anxiety (r = 0.27; P < 0.0001) and depression (r = 0.25; P < 0.0001) scores in patients with baseline HADS-A or HADS-D ≥8. Greater improvements in HADS were also observed at week 16 in guselkumab-treated patients vs. placebo using a more stringent cut-off of HADS ≥11.

CONCLUSION

Guselkumab treatment was associated with greater improvements in symptoms of anxiety and depression scores in patients with psoriasis compared with placebo and adalimumab.

Asian consensus on assessment and management of mild to moderate plaque psoriasis with topical therapy

A working group of dermatologists in Asian countries assessed the current status of psoriatic management in the region to prepare a consensus report on topical treatment in mild to moderate plaque psoriasis. Even though the association of psoriasis with systemic comorbidities is increasingly acknowledged, psoriasis is still lower in health‐care priority lists in the region. The psychosocial impact of psoriasis may be greater in Asian countries due to cultural norms and social discrimination. Non‐adherence to treatment is also common among Asians. The current care given to patients with mild to moderate psoriasis needs to be streamlined, enhanced and organized with a patient‐centered care approach to achieve better outcomes. A comprehensive assessment of the disease severity and its impact on a patient's life is required before initiating treatment. Education and active involvement of the patient in the treatment plan is an important part of psoriatic management. It is recommended to personalize topical treatment to meet the needs of the patient, depending on disease severity, psychosocial impact, the patient's expectations and, more importantly, the patient's willingness and ability to actively follow the treatment procedure. Fixed‐dose combination of corticosteroid and vitamin D analogs is the preferred topical medication for both initial and maintenance phases of treatment. The fast containment of the disease is the goal of the initial phase of 4–8 weeks and it demands a potent fast‐acting topical therapy. Satisfactory control of the disease and prevention of relapses should be achieved during the maintenance phase with twice a week or weekend applications.

Comparative effectiveness of biological therapies on improvements in quality of life in patients with psoriasis

Background

Evidence of the comparative effectiveness of biological therapies for psoriasis on health‐related quality of life (HRQoL) in routine clinical practice is limited.

Objectives

To examine the comparative effectiveness of adalimumab, etanercept and ustekinumab on HRQoL in patients with psoriasis, and to identify potential predictors for improved HRQoL.

Methods

This was a prospective cohort study in which changes in HRQoL were assessed using the Dermatology Life Quality Index (DLQI) and EuroQoL‐5D (EQ‐5D) at 6 and 12 months. Multivariable regression models were developed to identify factors associated with achieving a DLQI of 0/1 and improvements in the EQ‐5D utility score.

Results

In total, 2152 patients with psoriasis were included, with 1239 patients on adalimumab, 517 on etanercept and 396 on ustekinumab; 81% were biologic naïve. For the entire cohort, the median (interquartile range) DLQI and EQ‐5D improved from 18 (13–24) and 0·73 (0·69–0·80) at baseline to 2 (0–7) and 0·85 (0·69–1·00) at 6 months, respectively (P < 0·001). Similar improvements were achieved at 12 months. At 12 months, multivariable regression modelling showed that female sex, multiple comorbidities, smoking and a higher DLQI or a lower EQ‐5D utility score at baseline predicted a lower likelihood of achieving a DLQI of 0/1 or improvement in the EQ‐5D. Compared with adalimumab, patients receiving etanercept, but not ustekinumab, were less likely to achieve a DLQI of 0/1. There was no significant difference between the biological therapies in EQ‐5D improvement.

Conclusions

In routine clinical practice biological therapies produce marked improvement in HRQoL, which is influenced by the choice of biological therapy, baseline impairment in HRQoL, lifestyle characteristics and comorbidities. These findings should help inform selection of optimal biological therapy for patients related to improvements in HRQoL.

What's already known about this topic?

Evidence of the comparative effectiveness of biological therapies for psoriasis on health‐related quality of life (HRQoL) in routine clinical practice is limited.

Earlier observational studies were either cross‐sectional, thereby limiting the ability to compare changes in HRQoL, or cohort studies that have not taken into account important clinical factors that could influence treatment response, such as alterations in dosing regimens of biological therapies and the concomitant use of conventional systemic treatments for psoriasis.

What does this study add?

This large prospective cohort study found that in routine clinical practice, the use of biological therapies for psoriasis was associated with marked improvements in HRQoL over 12 months.

These improvements were influenced by the choice of biological therapy, baseline impairment in HRQoL, lifestyle characteristics and comorbidities.

Compared with adalimumab, patients receiving etanercept were less likely to achieve a DLQI of 0/1, but there was no significant difference between ustekinumab and adalimumab in the proportion of patients achieving a DLQI of 0/1.

There was no significant difference between the three biological therapies in level of improvement in the EQ‐5D.
