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). TRIAL REGISTRATION: ClinicalTrials.gov NCT02326298 (CIMPASI-1) and NCT02326272 (CIMPASI-2).

Development of antidrug antibodies against adalimumab maps to variation within the HLA-DR peptide-binding groove.

Targeted biologic therapies can elicit an undesirable host immune response characterized by the development of antidrug antibodies (ADA), an important cause of treatment failure. The most widely used biologic across immune-mediated diseases is adalimumab, a tumor necrosis factor inhibitor. This study aimed to identify genetic variants that contribute to the development of ADA against adalimumab, thereby influencing treatment failure. In patients with psoriasis on their first course of adalimumab, in whom serum ADA had been evaluated 6-36 months after starting treatment, we observed a genome-wide association with ADA against adalimumab within the major histocompatibility complex (MHC). The association signal mapped to the presence of tryptophan at position 9 and lysine at position 71 of the HLA-DR peptide-binding groove, with both residues conferring protection against ADA. Underscoring their clinical relevance, these residues were also protective against treatment failure. Our findings highlight antigenic peptide presentation via MHC class II as a critical mechanism in the development of ADA against biologic therapies and downstream treatment response.

Impact of psoriatic disease on women aged 18 to 45: Results from a multinational survey across 11 European countries.

BACKGROUND: Plaque psoriasis (PSO) is a long-term inflammatory condition that can cause concomitant joint symptoms (psoriatic arthritis [PsA]) in up to 30% of patients. The impact of psoriatic disease on disease outcomes and quality of life is greater in women than men. OBJECTIVE: We evaluated the impact of psoriatic disease on women aged 18 to 45 years across Europe. METHODS: Women aged 18 to 45 years with moderate to severe PSO, PsA, or PSO + PsA (PSO with progression to PsA) and prior biologic experience were recruited from market research panels and patient association groups of the International Federation of Psoriasis Associations, European Federation of Psoriasis Patient Associations, and Arthritis Ireland and asked to complete a survey. Questions covered social and psychological wellbeing, employment, and family planning. Question types included 5- or 7-point agreement scales, where the highest/lowest two ratings were considered agreement/disagreement, respectively. The results are reported as proportions of those who selected the answer, divided by overall respondents for each question. Women were not required to answer all questions. RESULTS: Survey respondents (N = 573) had a diagnosis of PSO (n = 236), PsA (n = 173), or PSO + PsA (n = 164). Women self-reported similar mean scores for physical (57.0 of 100) and mental (59.0 of 100) health. A fifth (21%) had not achieved their desired career due to PSO/PsA; career dissatisfaction and increased sick leave were linked to poor mental health. Some women reported having a limited social life (33%), smaller families (34%), and being more likely to adopt children (27%) due to PSO/PsA. A quarter of women (27%) reported not understanding enough about PSO/PsA (nonmembers vs. members of patient association groups: 37% vs. 8%). CONCLUSION: Our findings highlight the considerable burden of psoriatic disease on women of childbearing age. Increased provision of information tailored to women, training for health care professionals, and shared decision-making between patients and health care professionals may help better support women with psoriatic disease.

The real world impact of adalimumab on quality of life and the physical and psychological effects of moderate-to-severe psoriasis: a UK prospective, multicenter, observational study.

Psoriasis can adversely affect quality of life (QoL) and emotional well-being. In this UK prospective observational study we evaluated the 'real-world' impact of adalimumab on QoL and the physical/psychological effects of moderate-to-severe psoriasis. Hundred and forty-three biologic-naïve patients with moderate-to-severe psoriasis, receiving adalimumab in clinical practice, were included. Patients completed a series of questionnaires at baseline (adalimumab initiation), 4 and 16-weeks and 6-months post-adalimumab initiation during routine visits. The main outcome measure was the proportion of Dermatology Life Quality Index (DLQI) 'responders' at 16 weeks, defined as ≥5 point reduction from baseline or DLQI = 0.90% (95% CI = 80.8%-94.6%) of evaluable patients were DLQI responders at 16-weeks. There were significant improvements at 16 weeks in patient-reported measures of QoL, mental and physical well-being, cutaneous body image, anxiety, depression and psoriasis severity, which were maintained at 6-months. Adalimumab treatment was associated with improvements in patients' QoL and psychological functioning, which occurred contemporaneously with improvements in cutaneous disease.

Effect of Ixekizumab Treatment on Work Productivity for Patients With Moderate-to-Severe Plaque Psoriasis: Analysis of Results From 3 Randomized Phase 3 Clinical Trials.

IMPORTANCE: Therapies that reduce psoriasis symptoms may improve work productivity. OBJECTIVE: To assess the effect of ixekizumab therapy on work productivity, measured by the Work Productivity and Activity Impairment-Psoriasis (WPAI-PSO). DESIGN, SETTING, AND PARTICIPANTS: Three multicenter, randomized double-blind phase 3 trials conducted during the following periods: December 2011 through August 2014 (UNCOVER-1), May 2012 through April 2015 (UNCOVER-2), and August 2012 through July 2014 (UNCOVER-3). Adult outpatients with moderate-to-severe chronic plaque psoriasis were included. INTERVENTIONS: In UNCOVER-1, patients were randomized 1:1:1 to subcutaneous placebo or 80 mg ixekizumab every 2 weeks (Q2W) or every 4 weeks (Q4W) for 12 weeks; UNCOVER-2 and UNCOVER-3 also had an etanercept arm (50 mg twice weekly). Maintenance of initial ixekizumab response was evaluated in UNCOVER-1 and UNCOVER-2 during a randomized withdrawal period following week 12 through week 60. The WPAI-PSO questionnaire was administered at baseline and week 12 for all patients and at weeks 24, 36, 52, and 60 for patients in UNCOVER-1 and UNCOVER-2. MAIN OUTCOMES AND MEASURES: Change in work productivity from baseline as measured by WPAI-PSO scores. RESULTS: Across trials, 5101 patients consented; 3866 were randomized (mean [SD] age, UNCOVER-1, 45.7 [12.9] y, 68.1% male; UNCOVER-2: 45.0 [13.0] y, 67.1% male; UNCOVER-3: 45.8 [13.1] y, 68.2% male). At week 12 in UNCOVER-1, the ixekizumab Q4W and ixekizumab Q2W groups showed significantly greater improvements in WPAI-PSO scores (least squares mean change from baseline [SE]) relative to placebo: absenteeism (-3.5 [0.87], P < .001; -2.6 [0.84], P = .003, respectively, vs 0.2 [0.88]), presenteeism (-18.8 [1.28], P < .001; -18.3 [1.24], P < .001, vs 0.5 [1.30]), work productivity loss (-20.6 [1.38], P < .001; -19.8 [1.33], P < .001, vs -0.8 [1.40]), and activity impairment (-24.5 [1.18], P < .001; -25.2 [1.15], P < .001, vs 0.8 [1.18]). Similar results were obtained for UNCOVER-2 and UNCOVER-3, with the exception of absenteeism with ixekizumab Q4W in UNCOVER-2. Additionally, ixekizumab-treated patients showed significantly greater improvements in WPAI-PSO scores vs etanercept-treated patients: UNCOVER-2: presenteeism, work productivity loss, activity impairment (P < .001 both doses), UNCOVER-3: activity impairment (ie, regular activities outside of work) (ixekizumab Q2W; P = .009). Improvements in WPAI-PSO scores at week 12 were sustained to at least week 60. CONCLUSIONS AND RELEVANCE: Ixekizumab-treated patients reported short- and long-term improvements in work productivity, which could lead to reduced productivity-related cost burden in patients with psoriasis.

Attitudes and beliefs of an albino population toward sun avoidance: advice and services provided by an outreach albino clinic in Tanzania.

OBJECTIVE: To determine an albino population's expectations from an outreach albino clinic, understanding of skin cancer risk, and attitudes toward sun protection behavior. DESIGN: Survey, June 1, 1997, to September 30, 1997. SETTING: Outreach albino clinics in Tanzania. PARTICIPANTS: All albinos 13 years and older and accompanying adults of younger children attending clinics. Unaccompanied children younger than 13 years and those too sick to answer questions were excluded. Ninety-four questionnaires were completed in 5 villages, with a 100% response rate. INTERVENTIONS: Interview-based questionnaire with scoring system for pictures depicting poorly sun-protected albinos. RESULTS: The most common reasons for attending the clinic were health education and skin examination. Thirteen respondents (14%) believed albinism was inherited; it was more common to believe in superstitious causes of albinism than inheritance. Seventy-three respondents (78%) believed skin cancer was preventable, and 60 (63%) believed skin cancer was related to the sun. Seventy-two subjects (77%) thought sunscreen provided protection from the sun; 9 (10%) also applied it at night. Reasons for not wearing sun-protective clothing included fashion, culture, and heat. The hats provided were thought to have too soft a brim, to shrink, and to be ridiculed. Suggestions for additional clinic services centered on education and employment. Albinos who had read the educational booklet had no better understanding of sun avoidance than those who had not (P =.49). CONCLUSIONS: There was a reasonable understanding of risks of skin cancer and sun-avoidance methods. Clinical advice was often not followed for cultural reasons. The hats provided were unsuitable, and there was some confusion about the use of sunscreen. A lack of understanding of the cause of albinism led to many superstitions.

Psoriasis and psycho-dermatology.

INTRODUCTION: Psoriasis is a common, long-term skin condition associated with high levels of psychological distress and considerable life impact. The impact of psoriasis, beyond the skin, is often not recognised and under-treated. METHODS: This paper explores the relationship between psychological distress and psoriasis including reference to the 'brain-skin access'. The life impact of psoriasis is discussed and pharmacological interventions which affect distress associated with psoriasis and psychological interventions are reviewed. Evidence from peer-reviewed journals and controlled trials inform the text. RESULTS: Psoriasis has a profound impact on mental health and well-being which is under-recognised by clinicians. The sympathetic adrenal medullary axis and hypothalamic pituitary adrenal axis are likely to be involved in the onset of psoriasis and there may also be an effect from inflammation in the skin on the central release of corticotrophin-releasing hormone. Psoriasis can be stigmatising and may affect all aspects of life including relationships, employment, social life and leisure activities. There is some evidence for psychological interventions being effective in the management of distress associated with psoriasis and psoriasis itself. Studies, however, have used disparate outcomes and methods and largely involve low numbers of patients. There is very limited access to psychological support for the patients with psoriasis despite evidence of high levels of psychological distress and considerable life impact. CONCLUSIONS: Psoriasis is a long-term skin condition associated with high levels of distress and considerable life impact, both of which are under-recognised. Routine screening for distress with access to effective treatment is required. There is a need for high-quality studies to assess the effect of psychological intervention in patients with psoriasis both to inform guidance and facilitate the provision of effective psychological support services.

A cluster design controlled trial of arts-based observational skills training in primary care.

OBJECTIVE: To investigate whether the observational skills of doctors and nurses can be improved by arts-based observational skills training. METHODS: We carried out a cluster design, controlled trial involving 42 general practitioners and 26 primary care nurses in 12 primary care practices in London. Six practices were allocated to the intervention arm and 6 to the control arm. The intervention group received 90 minutes of arts-based observational skills training. The control group received practical training in the management of psoriasis. Before and after this, control and intervention participants were asked to describe 3 dermatological photographs. Descriptions were scored blindly against a predetermined marking key. Participants completed a questionnaire about the intervention, and about their own confidence in diagnosing and referring suspicious pigmented skin lesions. RESULTS: Post-intervention scores were significantly higher in the intervention group compared with the control group (P < 0.001). The majority of participants judged the intervention relevant, enjoyable and valuable. A majority lacked confidence in their dermatological knowledge and skills. DISCUSSION: This study provides statistically significant evidence that arts-based observational skills training can improve the observational skills of doctors and nurses. It is important not to overstate the clinical significance of these findings, and to recognise that observational skills are just one of many complex and subtle factors affecting the quality of the clinical process. Further research is needed to assess the existence, nature and clinical significance of longer-term benefits, and to identify differences between professional groups.
