Therapeutic goals and treatment response evaluation in moderate to severe psoriasis: an experts opinion document

Disease severity, treatment patterns, and quality of life in patients with moderate-to-severe psoriasis routinely managed with systemic treatment: results of the CRYSTAL observational study in Central and Eastern European countries

Psoriasis is a common, life-long skin disease with a significant negative health and societal impact. Data on rates of disease control and treatment strategies are lacking in Central and Eastern European countries. We aimed to describe the real-world disease severity, control, and treatment strategies for psoriasis in patients from Central and Eastern European countries. CRYSTAL (EUPAS36459) was a cross-sectional, retrospective study in adults (18-75 years) from Bulgaria, Estonia, Hungary, Latvia, Lithuania, Romania, and Russia. We enrolled patients with moderate-to-severe psoriasis receiving continuous systemic treatment for ≥24 weeks. We used the Psoriasis Area and Severity Index (PASI) to describe disease severity and the Dermatology Life Quality Index (DLQI) to assess quality of life (QoL) and collected other outcomes [psoriasis work productivity and activity impairment (WPAI-PSO), patient satisfaction] at enrollment. Analyses were descriptive. A total of 690 patients were included in the analyses. Median disease duration was 11.8 years. Current treatment was monotherapy for most patients (95.8%) with either biological (BIO group; 88.4%) or conventional (NON-BIO group; 7.4%) agents. Mean (± standard deviation) absolute PASI scores were 3.5 ± 5.7, 3.1 ± 5.3, and 6.6 ± 7.4 in the overall population, the BIO group, and the NON-BIO group, respectively. Among patients treated with monotherapy, absolute PASI scores ≤1, ≤3, and ≤5 were observed for 44.1%, 72.0%, and 82.6% of BIO patients and 21.6%, 33.3%, and 49.0% of NON-BIO patients. Mean DLQI total score was 3.3 ± 5.1; higher scores were noted for higher absolute PASI. The most impacted WPAI-PSO domain was presenteeism; for all domains, impact increased with increased absolute PASI. A total of 91.8% of BIO patients and 74.5% of NON-BIO patients were satisfied with the current treatment. We observed a better disease control in BIO than NON-BIO patients. However, around half of BIO patients did not reach clear skin status and reported an impact on QoL. An improvement in treatment strategies is still needed in Central and Eastern European countries to optimize outcomes of moderate-to-severe psoriasis.

Australian consensus: Treatment goals for moderate to severe psoriasis in the era of targeted therapies - Considerations for paediatric patients

BACKGROUND

Treatment goals have been established in Australia to facilitate the management of adults with moderate to severe psoriasis. The Australasian College of Dermatologists sought to determine if and how these adult treatment goals could be modified to accommodate the needs of paediatric and adolescent patients.

METHODS

A modified Delphi approach was used. Comprehensive literature review and guideline evaluation resulted in the development of statements and other questions to establish current clinical practices. Two rounds of anonymous voting were undertaken, with a collaborative meeting held in between to discuss areas of discordance. Overall, consensus was defined as achievement of ≥75% agreement in the range 7-9 on a 9-point scale (1 strongly disagree; 9 strongly agree).

RESULTS

Consensus was achieved on 23/29 statements in round 1 and 17/18 statements in round 2. There was a high level of concordance with treatment criteria in the adult setting. The limitations of applying assessment tools developed for use in adult patients to the paediatric setting were highlighted. Treatment targets in the paediatric setting should include objective metrics for disease severity and psychological impact on the patients and their family, and be based on validated, age-appropriate tools.

CONCLUSION

While the assessment, classification and management of moderate to severe psoriasis in paediatric patients aligns with metrics established for adults, it is vital that nuances in the transition from childhood to adolescence be taken into account. Future research should focus on psoriasis severity assessment scales specific to the paediatric setting.

Australian consensus: Treatment goals for moderate to severe psoriasis in the era of targeted therapies - Adult patients

BACKGROUND

Over the last decade, the treatment landscape for moderate-severe psoriasis has rapidly evolved. The Australasian College of Dermatologists sought to review and update previously published treatment goals for moderate-severe psoriasis.

METHODS

A modified Delphi approach was used. Comprehensive literature review and guideline evaluation resulted in the development of statements and other questions to establish current clinical practices. Two rounds of anonymous voting were undertaken, with a collaborative meeting held in between to discuss areas of discordance. Overall, consensus was defined as achievement of ≥75% agreement in the range 7-9 on a 9-point scale (1 strongly disagree; 9 strongly agree).

RESULTS

Consensus was achieved on 26/29 statements in round 1 and a further 20 statements in round 2. There was strong agreement to expanding the classification/definition of psoriasis severity by including a choice of metrics, incorporating quality of life measures, and widening the scope of high-impact sites. Consensus was also reached on revised treatment response criteria, which were then incorporated into a new treatment algorithm. There was discordance with the current requirement to undertake a trial with established systemic agents before accessing targeted therapy.

CONCLUSION

The ability of new targeted treatment options to change the narrative in psoriasis patient care can only be properly realised if challenges to timely and equitable access are addressed. The proposed framework for the assessment, classification and management of moderate-severe psoriasis aligns with international recommendations. Its adoption into Australian clinical practice is hoped to improve treatment outcomes and patients' satisfaction with their care.

Psoriasis Management Challenges Regarding Difficult-to-Treat Areas: Therapeutic Decision and Effectiveness

Psoriasis is not optimally controlled in spite of newly developed treatments, possibly due to the difficulty of objectively quantifying the disease's severity, considering the limitations of the clinical scores used in clinical practice. A major challenge addresses difficult-to-treat areas, especially in the absence of significant body surface involvement. It is controversial whether the severity evaluation of patients with several affected areas (having at least one difficult-to-treat area) should be done differently from current methods. Scores used for special areas (PSSI, NAPSI and ESIF) allow an accurate assessment of disease severity in difficult-to-treat areas, but the issue of whether to integrate these scores into PASI, BSA or DLQI remains. The review's purpose resides in providing an overview of the main current issues in determining psoriasis severity in patients with psoriasis in difficult-to-treat areas and suggesting possible solutions for the optimal integration of the area assessment in current scores: severity can be either established according to the highest calculated score (PASI or PSSI or NAPSI or ESIF) or by adding a correction factor in the calculation of PASI for special areas.

Therapeutic Failure In Moderate And Severe Psoriasis Patients In a Health Institution - a Transversal Study of Prevalence And Demographic Determinants

BACKGROUND

Psoriasis is a chronic disease that seriously impacts quality of life. There are known genetic and environmental factors that influence its onset and progression. Even though there is no cure for it, there are a variety of treatments available today to control its symptoms, although many of them fail to do so substantially.

OBJECTIVE

to identify the association of multiple sociodemographic, clinical, and pharmacological factors with therapeutic failure.

METHODS

observational, descriptive, cross-sectional, retrospective, and analytical study of therapeutic failure in patients with moderate or severe psoriasis between 2020 and 2021 was performed.

RESULTS

In total 1051 patients with moderate or severe psoriasis were evaluated. Gender (ORa: 0.579 CI95%: 0.382 - 0.878), type of therapy (biologic or non-biologic; ORa: 1.939 CI95%: 1.242 - 3.027), age (ORa: 1.018 CI95%: 1.003 - 1.034), days of treatment (ORa: 1 CI95%: 0.999 - 1) and DLQI (ORa: 1.212 CI95%: 1.172 - 1.253) are significantly associated with therapeutic failure.

CONCLUSION

Being male and receiving biologic therapy are associated with a higher incidence of therapeutic failure in the treatment of moderate or severe psoriasis. The increase in DLQI increase in the probability of failure, and mayor age or days of treatment decrease in the probability of failure.
