A systematic review of 454 randomized controlled trials using the Dermatology Life Quality Index: experience in 69 diseases and 43 countries. Br J Dermatol 2024; 190:315-339. [PMID: 36971254 DOI: 10.1093/bjd/ljad079] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2022] [Revised: 01/31/2023] [Accepted: 03/14/2023] [Indexed: 02/18/2024]
Abstract
BACKGROUND Over 29 years of clinical application, the Dermatology Life Quality Index (DLQI) has remained the most used patient-reported outcome (PRO) in dermatology due to its robustness, simplicity and ease of use. OBJECTIVES To generate further evidence of the DLQI's utility in randomized controlled trials (RCTs) and to cover all diseases and interventions. METHODS The methodology followed PRISMA guidelines and included seven bibliographical databases, searching articles published from 1 January 1994 until 16 November 2021. Articles were reviewed independently by two assessors, and an adjudicator resolved any opinion differences. RESULTS Of 3220 screened publications, 454 articles meeting the eligibility criteria for inclusion, describing research on 198 190 patients, were analysed. DLQI scores were primary endpoints in 24 (5.3%) of studies. Most studies were of psoriasis (54.1%), although 69 different diseases were studied. Most study drugs were systemic (85.1%), with biologics comprising 55.9% of all pharmacological interventions. Topical treatments comprised 17.0% of total pharmacological interventions. Nonpharmacological interventions, mainly laser therapy and ultraviolet radiation treatment, comprised 12.2% of the total number of interventions. The majority of studies (63.7%) were multicentric, with trials conducted in at least 42 different countries; 40.2% were conducted in multiple countries. The minimal clinically importance difference (MCID) was reported in the analysis of 15.0% of studies, but only 1.3% considered full score meaning banding of the DLQI. Forty-seven (10.4%) of the studies investigated statistical correlation of the DLQI with clinical severity assessment or other PRO/quality of life tools; and 61-86% of studies had within-group scores differences greater than the MCID in 'active treatment arms'. The Jadad risk-of-bias scale showed that bias was generally low, as 91.8% of the studies had Jadad scores of ≥ 3; only 0.4% of studies showed a high risk of bias from randomization. Thirteen per cent had a high risk of bias from blinding and 10.1% had a high risk of bias from unknown outcomes of all participants in the studies. In 18.5% of the studies the authors declared that they followed an intention-to-treat protocol; imputation for missing DLQI data was used in 34.4% of studies. CONCLUSIONS This systematic review provides a wealth of evidence of the use of the DLQI in clinical trials to inform researchers' and -clinicians' decisions for its further use. Recommendations are also made for improving the reporting of data from future RCTs using the DLQI.

Abstract
Background In France, psoriasis is a chronic inflammatory skin disease. For several years now, particular attention has been given to the quality of life (Qol) of psoriasis patients. Sexual dysfunction (SD) defined as not wanting or enjoying sexual experience is an important component of Qol. Psoriasis through its physical symptoms and psychological consequences can thus be responsible for SD. Method The survey participants were recruited through the national psoriasis dermatitis patient association. Result 41% (577) patients reported having SD related to their psoriasis. Women reported significantly more SD than men (387 [44.7%] vs. 190 [35%], p < 0.001). For 396 (28.1%) patients SD due to their psoriasis manifested as a reduction in the frequency of sexual activity, for 207 (14.7%) as change in their sexual practice, and for 284 (27.4%) as an absence of sexual activity without significant difference between women and men. The main consequence of sexual difficulties for patients was loss of self-confidence in 627 (44.5%) cases, guilt in 209 (14.8%) cases, couple life impairment in 214 (15.2%) cases, isolation in 260 (18.5%) cases and frustration. Discussion In this study investigating SD related to psoriasis, we found that the disease impact sexual relations of 41% of patients of both gender. The main causes of SD were both physical alone and psychological alone, in the same proportions. The physical symptoms of psoriasis are therefore not the only ones responsible for the sexual discomfort reported from patients in their sexual relations. This may be due to a discomfort of the patient or the physician when talking about sexuality because they can't find the terms to talk about this subject often considered taboo and the age or gender difference. This aspect of the disease should be considered by physicians who care for patients with psoriasis, especially dermatologists. Finally, other strategies should be implemented, such as patient talk groups, referral guides or personalised therapeutic education.

Abstract
BACKGROUND The Dermatology Life Quality Index (DLQI) is commonly used to assess the quality of life of patients with skin diseases. Clinical trials confirm the positive effect of the use of biologics and new molecules on the quality of life of patients with plaque psoriasis. MAIN OBJECTIVES Investigation of the effect of infliximab, adalimumab, ixekizumab, secukinumab and tofacitinib on Health-Related Quality of Life (HRQOL) measured by the DLQI in adult plaque psoriatic patients with respect to the patients' race, type of used agent/placebo, agent's dosage and treatment duration as well as the DLQI score prior to and after commencement of treatment. MATERIAL AND METHODS Systematic literature searching for referential papers written in English using four databases: PubMed, EMBASE, Scopus, ClinicalTrials.gov as well as and manual searching (Google) Cochran's (Q) and I2 tests were used for evaluation of heterogeneity or the degree of variation in the true effect size estimates between the analysed studies. The standardized mean difference (the SMD; Hedge's g score) was applied to measure the differences between the two means (i.e. two groups: treated vs non-treated or treated vs placebo). The data coding and Hedge's g values were calculated according to the guidance of MetaXL software version 5.3. MAIN RESULTS 43 studies, in total 25,898 individuals, were evaluated by the DLQI and weighted mean scores were derived for the analysis. The mean DLQI scores ranged from 6.83 to 17.8 with the overall DLQI score of 12.12 (95%CI: 11.24 to 13.06). A random-effects model demonstrated significant considerable heterogeneity of the study results (I2 = 98%; p<0.001). CONCLUSION Infliximab, adalimumab, ixekizumab, secukinumab and tofacitinib in adult plaque psoriatic patients improved HRQOL measured by the DLQI. The patients with lower quality of life before treatment obtained better results.

Abstract
Objective: To examine the prevalence of self-reported problems with sexual activity among psoriatic arthritis (PsA) patients, and to explore potential associations of such problems with various demographic, musculoskeletal, and dermatological disease variables. Method: Consecutive PsA patients were recruited from an outpatient clinic. Data collected included demographics, measures of musculoskeletal and skin disease activity, and treatments. Perceived effect of health status on sexual activity was assessed using question number 15 from the health-related quality of life instrument 15D; this was explored in univariate and multivariate logistic regression analyses. Results: The study assessed 135 patients (mean age 52.1 years, disease duration 8.7 years, 51.1% male). Mean scores included Maastricht Ankylosing Spondylitis Enthesitis Score (MASES) 2.9, Disease Activity index for PSoriatic Arthritis (DAPSA) 18.2, patient global assessment (PGA) 36.0 mm, pain 33.7 mm, fatigue 45.1 mm, modified Health Assessment Questionnaire (mHAQ) 0.42, Psoriasis Area Severity Index (PASI) 2.5, and Dermatology Life Quality Index (DLQI) 3.4. Twenty-four patients (17.8%) reported that their health status had a large negative effect and 111 (82.2%) that it had no or little effect on their sexual activity. In univariate analyses, a statistically significant association with impaired sexual activity was found for longer disease duration and higher MASES, DAPSA, PGA, fatigue, and mHAQ scores, but not for demographic variables or variables reflecting skin psoriasis involvement (PASI, DLQI). In adjusted analyses, only PsA disease duration remained independently associated with impaired sexual activity. Conclusion: One in five PsA patients perceived that their health status had a negative impact on sexual activity. Disease duration and measures reflecting musculoskeletal involvement, but not measures reflecting skin psoriasis involvement, appeared to be associated with impaired sexual activity.

Assessing the relative efficacy of interleukin-17 and interleukin-23 targeted treatments for moderate-to-severe plaque psoriasis: A systematic review and network meta-analysis of PASI response. PLoS One 2019; 14:e0220868. [PMID: 31412060 PMCID: PMC6693782 DOI: 10.1371/journal.pone.0220868] [Citation(s) in RCA: 101] [Impact Index Per Article: 20.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2019] [Accepted: 07/24/2019] [Indexed: 12/15/2022] Open
Abstract
INTRODUCTION New generation biologics, including interleukin (IL)-17 and IL-23 inhibitors, have delivered higher rates of skin clearance than older treatments in head-to-head studies. However, studies comparing these new biologics directly to one another are limited. OBJECTIVES To compare the short-term efficacy of available (or imminently available) biologic and non-biologic systemic therapies for treating patients with moderate-to-severe plaque psoriasis. METHODS A systematic review was undertaken to identify randomised controlled trials evaluating biologic treatments, apremilast and dimethyl fumarate. MEDLINE, MEDLINE In-Process, Embase and the Cochrane Library were searched from the 1st January 2000 to 22nd November 2018. A Bayesian network meta-analysis (NMA) using a random-effects multinomial likelihood model with probit link and meta-regression to adjust for cross-trial variation in placebo responses compared the efficacy of interventions at inducing different levels of Psoriasis Area and Severity Index (PASI) response during the induction period. A range of sensitivity analyses was undertaken. RESULTS Seventy-seven trials (34,816 patients) were included in the NMA. The base-case analysis showed that all active treatments were superior to placebo. IL-17 inhibitors, guselkumab and risankizumab were found to be more efficacious than tildrakizumab, ustekinumab, all TNF inhibitors and non-biologic systemic treatments at inducing all levels of PASI response. In addition, brodalumab, ixekizumab and risankizumab were significantly more efficacious than secukinumab; no significant difference was found in the comparison with guselkumab. The greatest benefit of brodalumab, ixekizumab, guselkumab, and risankizumab was seen for PASI 90 and PASI 100 response. Results were consistent across all analyses. CONCLUSIONS In the NMA brodalumab, ixekizumab, risankizumab and guselkumab showed the highest levels of short-term efficacy. There were differences in efficacy between treatments within the same class. Longer-term analyses are needed to understand differences between these drugs beyond induction in what is a life-long condition.

Abstract
Introduction: Psoriasis is a chronic immune-mediated skin disease with a multifactorial etiology. Studies have shown that the inflammatory cytokine interleukin-17A (IL-17A) is a key mediator in the pathogenesis. Targeted biologics have changed the outcome for patients in a variety of diseases including psoriasis. Ixekizumab is a humanized monoclonal antibody directed against IL-17A and it has been approved for the treatment of moderate-to-severe plaque psoriasis, and recently also psoriatic arthritis. Areas covered: In this review, we summarize the latest clinical study results on ixekizumab. Long-term Phase III study data on efficacy and safety are now available for both plaque psoriasis and psoriatic arthritis. Additionally, new indications for ixekizumab are under investigation. Expert commentary: Overall, the efficacy and safety of ixekizumab are promising. In plaque psoriasis, the efficacy of ixekizumab was superior to etanercept and ustekinumab, while the efficacy was comparable to adalimumab in psoriatic arthritis. The safety profile has also been found very tolerable and similar to other biologics; however, vigilance regarding non-invasive Candida infections is necessary. Also, caution is advised when treating patients with concomitant inflammatory bowel disease, since ixekizumab could cause exacerbations. Long-term studies in real-life treatment settings are needed to decide the actual potential and safety of ixekizumab.

Abstract
Objective: To review the efficacy, safety, and place in therapy of ixekizumab for the treatment of moderate to severe plaque psoriasis. Data Sources: PubMed (1966 to July 2018) and clinicaltrials.gov were searched using the terms ixekizumab, LY2439821, interleukin-17, and psoriasis. Study Selection and Data Extraction: Human studies published in peer-reviewed medical journals in English were used. Data Synthesis: The efficacy and safety of ixekizumab has been primarily reported by 4 phase III trials (UNCOVER-1, UNCOVER-2, UNCOVER-3, and UNCOVER-J) and multiple post hoc analyses. The average proportions of patients achieving a 75%, 90%, and 100% reduction in their Psoriasis Area and Severity Index (PASI) were 89%, 70%, and 38%, respectively, after 12 weeks of therapy. PASI75 was maintained for up to 3 years in 80.5% of participants. Ixekizumab was statistically significantly more effective than ustekinumab, with 76.5%, compared with 59%, of patients achieving PASI90 in 52 weeks. The most common adverse events include nasopharyngitis (14.1%), upper respiratory tract infections (7.9%), and injection-site reactions (6.8%), which are similar to that for other biological agents. The risk of inflammatory bowel disease may be increased with ixekizumab. Relevance to Patient Care and Clinical Practice: This review summarizes and evaluates clinical data regarding the efficacy and safety of ixekizumab and discusses relevant differences compared with other biological agents used for the management of chronic plaque psoriasis. Conclusions: Ixekizumab is a highly efficacious and well-tolerated treatment option for patients with moderate to severe plaque psoriasis.

Abstract
PURPOSE OF REVIEW Biologics and small molecules are key therapeutic options in the treatment of chronic immunologic and allergic skin conditions. By directly targeting innate and inflammatory responses within the skin, including pro-inflammatory cytokines and cellular signaling pathways, these new agents have the potential to counteract the inflammatory cascade responsible for various conditions, including psoriasis and atopic dermatitis. Over the past decade, groundbreaking research identifying key cytokines and receptors involved in the pathogenesis of these diseases has allowed for the development of highly efficacious biologics and small molecules that are associated with unprecedented rates of skin clearance and favorable adverse event profiles. RECENT FINDINGS This narrative review evaluates new and upcoming biologic and small molecule agents for the treatment of two allergic/immunologic skin diseases-atopic dermatitis and psoriasis. Numerous small molecules and biologics targeting TNF-α, IL-12/23, IL-17 and IL-17R, and IL-23 are commercially available for the treatment of psoriasis, and newer agents are in various stages of development. Currently, dupilumab, a monoclonal antibody that blocks IL-4R∝, is the only approved biologic for atopic dermatitis. Antibodies targeting IL-13 and IL-31 and small molecules that inhibit Janus kinase and pruritus-mediating receptors are currently being studied in clinical trials. Further investigations into the pathophysiology of atopic dermatitis will likely yield additional therapeutic options in the future. This article reviews recent literature on small molecules and biologics for the treatment of atopic dermatitis and psoriasis.

Abstract
INTRODUCTION Psoriasis is a common, immune-mediated skin disease often associated with significant physical and psychosocial impairment. Antipsoriatic biologic agents offer patients unparalleled treatment potential in regard to greater skin clearance and overall improved quality of life. Evaluation of the therapeutic efficacy of biologic agents on the full psoriasis disease burden must account for their impact on both physical symptoms, as well as patient-reported, health-related quality of life (HRQoL) measurements. Areas covered: Results from numerous clinical trials demonstrate the significant clinical efficacy of biological agents targeting tumor necrosis factor-α (TNF-α) and the interleukin (IL)-12/23 and IL-17 immune pathways. However, relatively limited data is available evaluating their full effect on quality of life outcomes. This review will discuss the most relevant and up-to-date clinical data on HRQoL measurements related to treatment with these aforementioned biologic agents. Expert commentary: Patient-reported outcomes (i.e. Dermatology Life Quality Index) are being used with increasing frequency in clinical trials, and provide valuable information on the impact of psoriasis on numerous aspects of day-to-day living. These outcomes must also be incorporated in clinical practice, in addition to physical assessment of disease severity, treatment decisions, and therapeutic response in the psoriasis patient population.

Abstract
Psoriasis vulgaris is a chronic, immune-mediated systemic disease that affectŝ7.5 million people in the US. It can be treated with many therapies, often in combination, which include topicals, phototherapy, oral systemics, and biologics. Biologic agents target specific components of the immune system involved in the pathogenesis of psoriasis including TNF-alpha, IL-12, IL-17, and IL-23. The biologic ixekizumab, approved for the treatment of moderate–severe plaque psoriasis in the US, targets IL-17. This review describes the role of IL-17 in psoriasis, the mechanism by which ixekizumab targets this cytokine, and the clinical utility of ixekizumab.
