Compared Burden of Psoriasis, Atopic Dermatitis, Hidradenitis Suppurativa, and Chronic Urticaria: Baseline Characteristics of the Patients Included in the OMCCI Cohort - A French, Prospective Multicenter Study of Chronic Inflammatory Dermatoses.

INTRODUCTION: Chronic inflammatory dermatoses (CIDs) can significantly affect patients' lives. The Observatory of Chronic Inflammatory Skin Diseases (OMCCI) cohort was initiated to quantify the impact and disease evolution of four CID over 4 years' follow-up; at least 1,000 patients per CID are planned to be enrolled. The objective of this study was to present baseline characteristics of patients included in the OMCCI cohort between December 2020 and September 2022. METHODS: This French, prospective, multicenter registry included adult patients treated in daily practice for moderate-to-severe psoriasis (PS), atopic dermatitis (AD), hidradenitis suppurativa (HS), or chronic urticaria (CU) starting or modifying a systemic treatment. At the inclusion visit and then every 6 months during 4 years, patient-reported outcomes and data on these diseases and their treatments are recorded. RESULTS: A total of 2,058 patients from 24 centers were included: 1,137 PS, 413 AD, 301 HS, and 207 CU. Of these, 1,950 patients started or changed systemic treatment, and 108 reduced the dose of existing systemic treatment. Disease impact was qualified as debilitating by 80.1% (PS), 90.5% (AD), 90.5% (HS), and 89.4% (CU), affecting daily, family, and professional life. According to the SF-12 Survey, the impact of all four diseases was borderline pathological for physical health and severe for mental health. At inclusion, 20.4% of patients were receiving a conventional systemic or biologic treatment. After the first visit, this percentage raised to 83.3%. During the 6 months preceding study inclusion, 17.7% (PS), 27.9% (AD), 43.1% (HS), and 43.6% (CU) of patients missed work due to their illness, and 26.3% of patients with HS had been admitted to hospital (vs. 8.1%, 5.8%, and 13% of patients with PS, AD, or CU, respectively). CONCLUSION: These CIDs (especially HS) had a major impact on all aspects of patients' quality of life. The low baseline use of systemic drugs and the high burden of these CIDs suggest that these agents are underused. Long-term and dynamic evaluation of the changes brought by the initiation or optimization of these treatments on the evolution of patients' lives will be studied prospectively during the 4-year follow-up of the OMCCI.

The patient's perspective on the burden of psoriasis: findings based on the ROCQ, an online survey.

Psoriasis is a common chronic skin disease, with well-characterised impact on quality-of life, however, no information is available on the lifetime impact of psoriasis on patients' lives. This descriptive cross-sectional web-based survey of patients with psoriasis, recruited from an online patient community, was conducted in France in 2021. Established questionnaires (Major Life-Changing Decision Profile-MLCDP, Dermatology Life Quality Index-DLQI, Hospital Anxiety and Depression Scale [HADS]), CAGE and BRIEF-COPE) were administered together with specially created questions. In total, 301 adult patients (mean age: 46.9 years; 56% women; mean disease duration: 20.3 years) participated in the study. The MLCDP showed that a mean of 9.4 life-changing decision items were affected; the most frequently cited domains being social life (n=258; 85.7%) and physical activity (n=226; 75.1%). In addition, 183 participants (60.7%) declared at least moderate impact of their psoriasis on their quality of life (score ≥6), with a median DLQI score of 7 [IQR: 3-13]. Impact on activities of daily living, such as social life, physical activities and marital relationships, was reported by over 50% of participants. Moreover, 107 (35.5%) declared being satisfied and 66 (21.9%) very satisfied with care. Over 50% of participants reported stigma related to being considered to have a contagious disease (n=182) or being unhygienic (n=163) and undesirable (n=167). Finally, 104 participants (34.6%) presented with clinically relevant anxiety and 32 (10.6%) clinically relevant depression (score ≥11) based on the HADS. Psoriasis carries a high psychological burden and has a strong long-term impact on social functioning.

Treatment of Severe Palmoplantar Pustular Psoriasis With Bimekizumab.

Importance: Palmoplantar pustulosis (PPP) and palmoplantar plaque psoriasis with pustules remain challenging to treat. Studies suggest that an interleukin 17 or interleukin 36 loop acts synergistically in these diseases to induce palmoplantar pustules. Objective: To assess the effectiveness of bimekizumab in treating PPP and palmoplantar plaque psoriasis with pustules. Design, Setting, and Participants: This case series involved 21 adults with PPP (11 patients) or palmoplantar plaque psoriasis with pustules (10 patients) treated at 1 of 7 tertiary dermatological centers in France from September 2022 through June 2023. All patients treated with bimekizumab for at least 3 months were included in the analyses. Main Outcomes and Measures: The main outcome was the posttreatment Investigator Global Assessment (IGA), scored as 0 (complete clearance), 1 (almost clear), 2 (mild), 3 (moderate), or 4 (severe). When relevant, evolution of joint pain and nail involvement was reported. Tolerance and potential adverse events were noted. Results: A total of 21 patients (mean [range] age, 46 [24-68] years; 19 females) were included. Eleven patients had isolated PPP, and 10 had palmoplantar plaque psoriasis with pustules. All of them, except 2 who received bimekizumab as first systemic therapy, had not responded to at least 1 systemic treatment (median [range], 3 [1-7] treatments), and/or had adverse events leading to the discontinuation of the treatment. Complete clearance (IGA score, 0) was achieved by 17 patients in 1 to 4 months. Three patients achieved an IGA score of 1, and 1 achieved an IGA score of 2. Three patients with PPP also presented with acrodermatitis continua of Hallopeau. Nail involvement showed 50% to 70% improvement after 4 to 6 months of bimekizumab treatment for these 3 patients. Two patients had SAPHO (synovitis, acne, pustulosis, hyperostosis, osteitis) syndrome; both had complete clearance of skin lesions associated with joint pain improvement. Four patients (19%) with candidiasis were successfully treated with oral antifungal agents. None of the patients had to stop bimekizumab treatment due to adverse events. Conclusions and Relevance: The findings of this case series suggest that bimekizumab could be an appealing approach for treating PPP, palmoplantar plaque psoriasis with pustules, and SAPHO syndrome. Prospective randomized placebo-controlled clinical trials are needed to confirm these encouraging initial results.

Impact of Baricitinib on Patients' Quality of Life after One Year of Treatment for Atopic Dermatitis in Real-World Practice: Results of the Observatory of Chronic Inflammatory Skin Diseases Registry.

The efficacy and safety of baricitinib for treatment of atopic dermatitis have been demonstrated in clinical trials; however, very few real-life studies have been published to date. The Observatory of Chronic Inflammatory Skin Diseases (OMCCI) registry was initiated to prospectively determine the long-term impairment caused by chronic inflammatory dermatoses on patients' lives. The study included 88 patients starting baricitinib for treatment of atopic dermatitis. Clinical evaluation and patient-reported outcomes were recorded at baseline and after 6 and 12 months. After 6 months and 1 year of follow-up, 65 and 47 patients, respectively, were still being treated with baricitinib. Treatment failure was the main reason for discontinuation. Only 1 patient stopped baricitinib because of a side-effect. After 1 year of follow-up, the mean Eczema Area and Severity Index score decreased significantly from 20.7 to 6.4; the percentage of patients with severe atopic dermatitis decreased from 42.9% to 6.5% and a significant improvement in most patient-reported outcomes was noted. There was no difference in terms of efficacy whether or not patients were previously treated with dupilumab. The results remained stable after 6 and 12 months of treatment, which suggests a sustained efficacy of the treatment in patients who initially responded well.

Effectiveness of biologic therapies in children with palmoplantar plaque psoriasis: An analysis of real-life data from the BiPe cohorts.

BACKGROUND: Palmoplantar plaque psoriasis is a frequent clinical subtype of childhood psoriasis. This study evaluated the effectiveness of biologic therapies in children with palmoplantar plaque psoriasis using data from the two Biological treatments for Pediatric Psoriasis (BiPe) cohorts. METHODS: Data for all 170 patients included in the BiPe cohorts were analyzed. Data on the effectiveness (PGA, PASI between baseline and 3 months of treatment) of biologic therapies were then compared between children with palmoplantar plaque psoriasis (n = 20) and those with generalized plaque psoriasis (n = 136). Clinical and demographic data were also analyzed. RESULTS: Children in the palmoplantar group were more likely to be male (p = .04), with an earlier age of psoriasis onset (p < .001), and more frequent nail involvement (p < .001). After 3 months of biologic treatment, mean PGA scores were higher in the palmoplantar group than in the generalized plaque psoriasis group (p = .004). In the palmoplantar group, continuation rates were higher for adalimumab than for etanercept or ustekinumab (p = .01). Primary inefficacy was a more frequent reason for stopping biologic therapies in the palmoplantar group (p = .01), and disease remission was less frequent (p = .05). Combined systemic and biologic therapies were more frequently used in palmoplantar plaque psoriasis (p < .001). CONCLUSIONS: This study demonstrated the treatment-resistant nature of palmoplantar plaque psoriasis and indicated that adalimumab could be the most effective biologic treatment. Larger studies are needed to allow therapeutic algorithms for palmoplantar plaque psoriasis to be proposed in pediatric psoriasis management guidelines.

Effectiveness and Safety of Adalimumab, Etanercept and Ustekinumab for Severe Psoriasis in Children Under 12 Years of Age: A French-Italian Daily Practice Cohort (BiPe Jr).

INTRODUCTION: Biological therapies are valuable treatments for severe psoriasis. Children aged under 12 years are underrepresented in therapeutic trials for these drugs. The objective of the 'BiPe Jr' cohort study was to evaluate the drug survival, effectiveness, tolerance and switching patterns of biological therapies in children under 12 years of age with psoriasis. METHODS: We conducted a multicentre retrospective study of children with psoriasis who received at least one injection of a biological agent, even off-licence, before the age of 12 years in France and Italy, collecting the data between April and August 2021. The data collected were from March 2012 up to August 2021. RESULTS: In total, 82 children (mean age: 9.1 years; females: 61.0%) received 106 treatments. The drugs administered were adalimumab (n = 49), etanercept (n = 37), ustekinumab (n = 15), anakinra (n = 2), infliximab (n = 2) and secukinumab (n = 1). The most common form of psoriasis was plaque psoriasis (62.9%). The Physician Global Assessment and the Psoriasis Area Severity Index (PASI) scores decreased significantly from baseline to 3 months after treatment initiation for the three main biological drugs; PASI went from 14.1 ± 9.4 to 4.1 ± 11.3 for adalimumab (p = 0.001), 14.9 ± 9.3 to 5.1 ± 4.0 for etanercept (p = 0.002) and 11.6 ± 8.3 to 2.6 ± 2.2 for ustekinumab (p = 0.007). A trend towards higher 2-year maintenance rates was observed for ustekinumab and adalimumab, compared with etanercept (p = 0.06). 52 children discontinued their biological therapy, most frequently due to inefficacy (n = 28) and remission (n = 14). Seven serious adverse events (SAEs) were reported, including four severe infections. DISCUSSION: Our analyses of drug survival and treatment patterns, combined with those of previous studies conducted in older children, indicate that there is a trend towards higher 2-year survival rates of ustekinumab and adalimumab. The SAEs identified were rare, but highlight the need for increased vigilance concerning infections. Overall, the biological therapies showed good effectiveness and safety profiles when used in daily practice for the treatment of young children with psoriasis.

Effectiveness and Safety of Anti-interleukin-17 Therapies in Elderly Patients with Psoriasis.

Anti-interleukin-17 agents have recently been developed for the treatment of psoriasis. This study evaluated the tolerance and effectiveness of anti-interleukin-17 agents for psoriasis in elderly patients in daily practice. A multicentre, retrospective study was performed, involving psoriatic patients aged ≥65 years who had received an anti-interleukin-17 agent, including secukinumab, ixekizumab or brodalumab. A total of 114 patients were included: 72 received secukinumab, 35 ixekizumab, and 7 brodalumab. Treatment was stopped in 32 patients (28.9%), because of relapses in 14 patients (41.2%), primary failures in 11 patients (32.4%), or adverse events in 7 patients (20.6%). The 3 most frequently reported adverse events were injection site reactions (n = 4), oral candidiasis (n = 3), and influenza-like illness (n = 3). Regarding effectiveness, 80 patients (70%) reached a Physician Global Assessment score of 0/1, 6 months after treatment initiation. In conclusion, anti-interleukin-17 therapy appears to be an effective and safe therapeutic option for psoriasis treatment in patients aged ≥ 65 years.

Development of monoclonal gammopathy under biotherapy in psoriasis: a French multicenter retrospective study.

BACKGROUND: Biotherapies or targeted therapies are fairly new treatments indicated for moderate to severe psoriasis. The side effects appear to be mainly infectious or cancerous. The role of biotherapies in the development of a pre-cancerous condition, monoclonal gammopathy of undetermined significance (MGUS), has recently been debated in the literature. OBJECTIVES: To evaluate the incidence of MGUS in psoriasis patients treated with biotherapy. MATERIALS AND METHODS: This study was a French multicenter retrospective study carried out through the French multicenter study group RESOPSO. Data on the results of serum protein electrophoreses performed before and within at least six months after the start of the biotherapy were collected. Demographic data, medical history, and psoriasis treatment history were specified. RESULTS: Four hundred and forty three patients were eligible for inclusion. Of these, three presented with monoclonal gammopathy for which the assessment was in favor of MGUS. The average treatment period was 19.7 months. Six patients presented with MGUS prior to the treatment. These patients' immunoglobulin levels remained stable, with an average remission of 24 months. Only psoriatic rheumatism appeared to be statistically linked to MGUS. CONCLUSION: The incidence and frequency of MGUS in psoriasis patients treated with biotherapy do not appear to increase relative to the general population.
