Impact of light dose and fluence rate on the efficacy and tolerability of topical 5-ALA photodynamic therapy for actinic keratoses: A randomized, controlled, observer-blinded intrapatient comparison study.

Background: Conventional photodynamic therapy (cPDT) is an effective treatment option for field cancerization and multiple actinic keratoses (AK). The main side effect of cPDT is pain during illumination which in severe cases might necessitate early termination of treatment. Modification of treatment parameters such as light dose and fluence rate is a promising approach to mitigate PDT-associated pain.

Evolution of characteristics and biologic treatment effectiveness in patients of the Austrian psoriasis registry from 2004-2022.

Background And Objectives: This study analyzed the extent to which the recent introduction of more effective treatments has led to an improvement in real-world psoriasis patients.

Patients And Methods: Patient characteristics and the first-year treatment effectiveness in biologic-naive patients have been analyzed since 2004 until now, irrespective of treatment switches.

Results: Data from 2,729 patients were eligible for this analysis.

Real-world effectiveness of anti-interleukin-23 antibodies in chronic plaque-type psoriasis of patients from the Austrian Psoriasis Registry (PsoRA).

With the introduction of the latest class of biologic drugs targeting interleukin (IL)-23p19, three new, highly effective drugs can be used for the treatment of chronic plaque psoriasis. However, poorer skin improvement as well as higher rates of serious adverse events have been reported for patients under real-world conditions (outside clinical trials). This accounts especially for patients who have already been treated with biologic drugs.
