Treatment modalities and risk of adverse events associated with biologic therapy: A 10-year observational review of the Australasian Psoriasis Registry

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.

Clinical and patient-reported outcomes from the first 4 years of a Psoriasis Biologics Registry in Singapore

Interim analysis of the National Skin Centre Singapore Psoriasis Biologics Registry (SINGPSOR) from August 2017 to May 2021, in which 58 patients were analysed, showing that those receiving biologic treatment had significantly more severe psoriasis based on PASI (Psoriasis Area and Severity Index), BSA (body surface area) and PGA (Physician Global Assessment) measures at baseline, demonstrated a statistically non-significant trend towards greater improvement with treatment, and had a lower percentage of adverse events compared to those receiving conventional systemic therapy. Future analyses of SINGPSOR, with larger sample size and longer follow-up, will be invaluable to further characterize these patients and their treatment outcomes.

Effect of Chinese herbal medicine injections for treatment of psoriasis vulgaris: a systematic review and meta-analysis

Background: Psoriasis vulgaris (PV) is a longstanding, inflammatory, immune-responsive skin condition. Chinese herbal medicine injections (CHMIs) have been utilized for treating PV in Asian countries. This study aims to conduct a thorough systematic review and meta-analysis to comprehensively appraise the efficacy of CHMIs in treating PV. Methods: Seven databases were searched for randomized controlled trials that evaluated the effect of CHMIs in treating PV, ranging from 2004 to June 2022. The meta-analysis was undertaken based on outcome measures, treatment options, and treatment durations using Review Manager 5.4. The primary outcome measure of this study was a 60% or higher reduction in the Psoriasis Area and Severity Index score (PASI 60). A descriptive analysis was performed for the assessment of adverse events. Results: This systematic review incorporated 33 studies, comprising 3,059 participants. The main findings indicated significant differences based on the PASI 60 (RR = 1.30, 95% CI: 1.24 to 1.37, Z = 10.72, p < 0.00001), PASI 30 (RR = 1.25, 95% CI: 1.13 to 1.38, Z = 4.48, p < 0.00001), and PASI 20 (RR = 1.28, 95% CI: 1.13 to 1.45, Z = 3.82, p = 0.0001) outcome measures. Evaluating the treatment options, CHMIs in combination with monotherapies like narrowband ultraviolet B (NB-UVB) and the acitretin capsule (AC) showed a greater reduction in PASI 60 (RR = 1.33, 95% CI: 1.25 to 1.43, Z = 8.32, p < 0.00001). In terms of treatment duration, no significant difference was observed when the duration extended beyond 56 days. Furthermore, the results suggested that CHMIs might reduce the incidence of adverse events in the treatment of PV. Conclusion: This systematic review revealed preliminary clinical evidence supporting the use of CHMIs for treating PV, considering outcome measures, treatment options, and treatment durations. However, due to the low methodological quality and limited sample size of the included studies, there is an urgent need for high-quality, multi-center and larger-scale studies of CHMIs for PV to provide robust evidence for their clinical application.
