Abstract
The evidence on treating older patients with psoriasis with modern biologics is scarce. This study compared the efficacy and safety of tildrakizumab among younger and older patients with psoriasis (< 65/≥ 65 years) in a post hoc analysis of 2 phase III trials (reSURFACE1/2, n = 1,862). Tildrakizumab 100 mg/200 mg was administered at weeks 0/4/every 12 weeks thereafter. At week 28, patients with ≥ 75% improvement in baseline Psoriasis Area and Severity Index (PASI75) in reSURFACE1 were re-randomized to the same tildrakizumab dose or placebo; in reSURFACE2, PASI75 responders to 200 mg were re-randomized to tildrakizumab 100 mg or 200 mg; PASI75 responders to 100 mg maintained their dose. At weeks 64/52 (reSURFACE1/2), PASI50 responders entered an extension period (weeks 256/244). Outcomes were proportion of patients with PASI < 3, Dermatology Life Quality Index (DLQI) 0/1, comorbidities, comedication, and side-effects. The proportion of patients with a PASI < 3 was similar and maintained (tildrakizumab 100 mg and 200 mg, week 244: 83.3% and 84.1%/92.3% and 100.0%); DLQI 0/1 proportions at week 52 were 66.8% and 72.0%/68.3% and 81.3%. Comorbidity and comedication were more common in older patients. The safety profile of tildrakizumab appeared favourable in both groups. Tildrakizumab in patients ≥ 65 years appears effective and safe in long-term psoriasis management. These findings might assist treatment selection and overcome treatment reluctance.

Abstract
Managing moderate to severe psoriasis in older adults is complex due to factors characteristic of the later years of life, such as associated comorbidity, polypharmacy, and immunosenescence. This consensus statement discusses 17 recommendations for managing treatment for moderate to severe psoriasis in patients older than 65 years. The recommendations were proposed by a committee of 6 dermatologists who reviewed the literature. Fifty-one members of the Psoriasis Working Group of the Spanish Academy of Dermatology and Venereology (AEDV) then applied the Delphi process in 2 rounds to reach consensus on which principles to adopt. The recommendations can help to improve management, outcomes, and prognosis for older adults with moderate to severe psoriasis.

Abstract
Purpose Secukinumab is a fully human monoclonal antibody that inhibits interleukin (IL)-17A approved for the treatment of moderate to severe plaque psoriasis in adults and children. We compared the efficacy and safety of secukinumab in patients aged < 65 years (adult patients) versus patients aged ≥ 65 years (elderly patients) in a post-hoc analysis of the SUPREME study. Patients and Methods Patients with moderate to severe plaque psoriasis received subcutaneous secukinumab 300 mg per week for the first 5 weeks, then 300 mg per month. We compared the following outcomes in patients aged ≥ 65 years vs < 65 years: baseline characteristics; PASI50/75/90/100 response rates (improvements ≥ 50%/75%/90%/100% in Psoriasis Area and Severity Index (PASI) from baseline); changes in Dermatology Life Quality Index (DLQI); Hospital Anxiety and Depression Scale (HAD-A, HAD-D) score changes; treatment-emergent adverse events (TEAEs). Results Secukinumab was slightly less effective in elderly patients than in adult patients (response rates at week 16: PASI90, 69.4% vs 80.9%, p = 0.4528; PASI100, 44.4% vs 56.7%, p = 0.8973). Elderly and adult patients showed a similar time course of changes in absolute PASI scores. Patients aged ≥ 65 years had a statistically significantly lower improvement in quality of life (mean DLQI reduction) than patients aged < 65 years at week 16 [-5.4 (±4.3) vs -8.8 (±6.9), p = 0.0065] and at week 24 [-5.3 (±4.4) vs -9.2 (±7.1), p = 0.0038]. Secukinumab treatment resulted in comparable mean reductions in anxiety and depression scores in both cohorts at 24 weeks [HAD-A, -1.3 (±3.3) vs -2.1 (±3.8), p = 0.9004; HAD-D, -1.0 (±3.3) vs -1.5 (±3.1), p = 0.4598]. The frequency of TEAEs in the two cohorts was similar (16.7% vs 14.6%, p = 0.7391). Conclusion Secukinumab is a valid option for the management of moderate to severe psoriasis in elderly patients.

Drug Survival, Safety, and Effectiveness of Biologics in Older Patients with Psoriasis: A Comparison with Younger Patients-A BioCAPTURE Registry Study. Drugs Aging 2022; 39:715-727. [PMID: 35859228 PMCID: PMC9300332 DOI: 10.1007/s40266-022-00961-y] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 06/08/2022] [Indexed: 11/03/2022]
Abstract
BACKGROUND Psoriasis is a common inflammatory disease in any age group, but also in older patients (≥ 65 years of age). Since older patients are often excluded from clinical trials, limited data specifically on this growing population are available, e.g. regarding the safety and performance of biological treatment. AIMS We aimed to give insight into this specific population by comparing the drug survival and safety of biologics in older patients with that in younger patients. METHODS In this real-world observational study, data from 3 academic and 15 non-academic centers in The Netherlands were extracted from the prospective BioCAPTURE registry. Biologics included in this study were tumor necrosis factor (TNF)-α, interleukin (IL)-17, IL-12/23, and IL-23 inhibitors. Patients were divided into two age groups: ≥ 65 years and < 65 years. The Charlson Comorbidity Index (CCI) was used to measure comorbid disease status, and all adverse events (AEs) that led to treatment discontinuation were classified according to the Medical Dictionary for Regulatory Activities (MedDRA) classification. All AEs that led to treatment discontinuation were studied to check whether they could be classified as serious AEs (SAEs). Kaplan-Meier survival curves for overall 5-year drug survival and split according to reasons of discontinuation (ineffectiveness or AEs) were constructed. Cox regression models were used to correct for possible confounders and to investigate associations with drug survival in both age groups separately. Psoriasis Area and Severity Index (PASI) scores during the first 2 years of treatment and at the time of treatment discontinuation were assessed and compared between age groups. RESULTS A total of 890 patients were included, of whom 102 (11.4%) were aged ≥ 65 years. Body mass index, sex, and distribution of biologic classes (e.g. TNFα, IL12/23) were not significantly different between the two age groups. A significantly higher CCI score was found in older patients, indicative of more comorbidity (p < 0.001). The 5-year ineffectiveness-related drug survival was lower for older patients (44.5% vs. 60.5%; p = 0.006), and the 5-year overall (≥ 65 years: 32.4% vs. < 65 years: 42.1%; p = 0.144) and AE-related (≥ 65 years: 82.1% vs. < 65 years: 79.5%; p = 0.913) drug survival was comparable between age groups. Of all AEs (n = 155) that led to discontinuation, 16 (10.3%) were reported as SAEs but these only occurred in younger patients. After correcting for confounders, the same trends were observed in the drug survival outcomes. Linear regression analyses on PASI scores showed no statistical differences at 6, 12, 18, and 24 months of treatment between age groups. CONCLUSIONS This study in a substantial, well-defined, prospective cohort provides further support that the use of biologics in older patients seems well-tolerated and effective. Biologic discontinuation due to AEs did not occur more frequently in older patients. Older patients discontinued biologic treatment more often due to ineffectiveness, although no clear difference in PASI scores was observed. More real-world studies on physician- and patient-related factors in older patients are warranted.

Abstract
BACKGROUND Evidence-based guidance in older adults (≥65 years) with psoriasis is sparse and undertreatment might be present. OBJECTIVES To assess prescribing patterns, comfort levels, barriers and needs of dermatologists when treating older adults with systemic antipsoriatic therapy. METHODS A mixed-methods design was used including a survey among all Dutch dermatologists and residents, followed by semi-structured interviews. RESULTS Most of the survey respondents applied systemic treatment to the same extent in older versus younger patients (n = 49; 67.1%) and weren't reluctant prescribing systemic therapy (n = 50; 68.5%) in older adults. However, 26% (n = 19) of the respondents treated older adults less often with systemic therapy compared to younger patients and 68.1% (n = 49) performed additional actions in older adults, e.g. intensified monitoring or dose reduction. Based on the survey and interviews (n = 10), the main reasons for these age-based treatment differences were comorbidity, comedication, and fear of adverse events. More evidence-based guidance, education, and time to assess older adults were identified as most important needs, especially regarding frailty screening. CONCLUSIONS Age-based treatment differences in and reluctance to treating older adults with systemic antipsoriatic therapy were common. There is a need for more evidence-based guidance, education, and consultation time, to improve treatment in this growing population.

Abstract
BACKGROUND Treatment needs of young psoriasis patients and parents are not widely studied and could advance patient-centered care. OBJECTIVE To explore treatment goals and preferences of pediatric psoriasis patients, young adults, and parents. METHODS A web-based survey among Dutch psoriasis patients aged ≥6 to ≤30 years and parents included multiple-choice, open-ended, and 4-point Likert scale questions. Treatment goals and characteristic preferences of pediatric patients (≤17 years) were compared to young adults (≥18 years) and parents. RESULTS 195 young patients (20.2 ± 6.3 years) and 45 parents were included. The most important treatment goals were 'preventing lesions', 'reducing lesions', 'no itch', and 'no lesions'. Regarding treatment characteristics, 'long-term safety', 'high effectiveness', and 'short-term safety' were most important. We found differences by age, gender, and current treatment. Pediatric patients rated 'not sticky', 'quick results', and 'no/few blood samples needed' higher than parents and/or young adults. Young adults rated 'feeling more confident' and 'better quality of sleep' higher than pediatric patients. Parents considered safety most important. Psychosocial goals were more important for women and patients on biologics. CONCLUSION Young psoriasis patients and parents mainly strive to clear lesions and itch with effective and safe treatment. However, revealed differences underline the relevance of addressing individual needs.

Abstract
OBJECTIVES Dermatology Life Quality index (DLQI) is the most widely used health-related quality of life questionnaire in dermatology. Little is known about existing questionnaire or scoring modifications of the DLQI. We aimed to systematically review, identify, and categorize all modified questionnaire versions and scoring methods of the DLQI. METHODS We performed a systematic literature search in PubMed, Web of Science, CINAHL, and PsychINFO. Methodologic quality and evidence of psychometric properties were assessed using the Consensus-Based Standards for the Selection of Health Measurement Instruments (COSMIN) and Terwee checklists. RESULTS The included 81 articles reported on 77 studies using 59 DLQI modifications. Modifications were used for a combined sample of 25 509 patients with 47 different diagnoses and symptoms from 28 countries. The most frequently studied diseases were psoriasis, hirsutism, acne, alopecia, and bromhidrosis. The modifications were categorized into the following nonmutually exclusive groups: bolt-ons or bolt-offs (48%), disease, symptom, and body part specifications (42%), changes in existing items (34%), scoring modifications (27%), recall period changes (19%), response scale modifications (15%), and illustrations (3%). The evidence concerning the quality of measurement properties was heterogeneous: 4 of 13 studies were rated positive on internal consistency, 1 of 3 on reliability, 3 of 5 on content validity, 9 of 22 on construct validity, 6 of 6 on criterion validity, and 1 of 1 on responsiveness. CONCLUSION An exceptionally large number of DLQI modifications have been used that may indicate an unmet need for adequate health-related quality of life instruments in dermatology. The psychometric overview of most questionnaire modifications is currently incomplete, and additional efforts are needed for proper validation.

Abstract
PURPOSE Eight of the ten items of the Dermatology Life Quality Index (DLQI) have a 'not relevant' response (NRR) option. There are two possible ways to interpret NRRs: they may be considered 'not at all' or missing responses. We aim to compare the measurement performance of the DLQI in psoriasis patients when NRRs are scored as '0' (hereafter zero-scoring) and 'missing' (hereafter missing-scoring) using Rasch model analysis. METHODS Data of 425 patients with psoriasis from two earlier cross-sectional surveys were re-analysed. All patients completed the paper-based Hungarian version of the DLQI. A partial credit model was applied. The following model assumptions and measurement properties were tested: dimensionality, item fit, person reliability, order of response options and differential item functioning (DIF). RESULTS Principal component analysis of the residuals of the Rasch model confirmed the unidimensional structure of the DLQI. Person separation reliability indices were similar with zero-scoring (0.910) and missing-scoring (0.914) NRRs. With zero-scoring, items 6 (sport), 7 (working/studying) and 9 (sexual difficulties) suffered from item misfit and item-level disordering. With missing-scoring, no misfit was observed and only item 7 was illogically ordered. Six and three items showed DIF for gender and age, respectively, that were reduced to four and three by missing-scoring. CONCLUSIONS Missing-scoring NRRs resulted in an improved measurement performance of the scale. DLQI scores of patients with at least one vs. no NRRs cannot be directly compared. Our findings provide further empirical support to the DLQI-R scoring modification that treats NRRs as missing and replaces them with the average score of the relevant items.
