The Effect of Lifestyle Changes on Disease Severity and Quality of Life in Patients with Plaque Psoriasis: A Narrative Review

The Effectiveness of Risankizumab Following Guselkumab Failure in Moderate-to-Severe Psoriasis Patients: A Retrospective Study

BACKGROUND

Psoriasis is a chronic inflammatory skin disease with a strong genetic predisposition and autoimmune component that is often treated with immunomodulators such as biologic therapy. Guselkumab is a biologic treatment option that selectively targets the p19 subunit of interleukin (IL)-23; risankizumab is a more recently developed monoclonal antibody of the same class that targets IL-23p19. There is limited research around effective treatment response with intra class switching within IL-23-targeted therapies for the treatment of moderate-to-severe plaque psoriasis.

OBJECTIVES

The purpose is to assess patient response to risankizumab after guselkumab failure for the treatment of plaque psoriasis.

METHODS

A retrospective chart review was conducted for 13 patients meeting inclusion criteria. Physical examination findings were converted to a 5-point static physicians' global assessment (sPGA) score. Baseline, 4-month, and 12-month sPGA scores were assigned from visits immediately prior to and during their course of risankizumab treatment. sPGA scores were analyzed to compare changes between baseline and 4 months and 12 months of therapy.

RESULTS

Patients treated with risankizumab had lower sPGA scores after both 4 and 12 months compared to their baseline sPGA score. 46% of patients met the primary outcome of an sPGA score of 0 or 1 at 4 months of risankizumab, increasing to 90% of patients at 12 months.

CONCLUSIONS

Our findings reflect an improvement in sPGA scores when patients are treated with risankizumab following guselkumab failure. This highlights the benefit of in-class switch to risankizumab when patients with moderate-to-severe plaque psoriasis have failed multiple treatments including guselkumab.

Impact of Alcohol Consumption, Smoking, and Diet on the Severity of Plaque Psoriasis: A Comprehensive Assessment using Clinical Scales and Quality of Life Measures

BACKGROUND This study aimed to evaluate the effects of alcohol intake, assessed using the Alcohol Use Disorder Identification Test (AUDIT) questionnaire, on the severity of plaque psoriasis using the Body Surface Area (BSA) and Psoriasis Area and Severity Index (PASI) scales, and quality of life using the Dermatology Life Quality Index (DLQI) questionnaire. MATERIAL AND METHODS The diagnosis of psoriasis was made based on the clinical picture. We enrolled 24 patients with psoriasis vulgaris, and the AUDIT test conducted at the time of follow-up indicated a possible risky/harmful pattern of alcohol consumption or alcohol dependence syndrome among the patients (>8 points). The comparison group consisted of 20 psoriatic patients and AUDIT <8 points. The BSA and PASI scales were used to determine the severity of psoriasis, and the DLQI questionnaire assessed patients' quality of life and how they felt during the week preceding the survey. RESULTS As the amount and frequency of alcohol consumed increased, the exacerbation of lesions measured according to the PASI and BSA scales was significantly higher (P<0.05), and the quality of life decreased (P<0.05). We noted that inadequate and excessive dietary intake of total protein, total fat, and assimilable carbohydrates were associated with statistically significantly higher values of BSA and PASI scores and, thus, more severe psoriatic lesions (P<0.05). CONCLUSIONS An unbalanced diet, alcohol abuse, and smoking negatively affect the course of psoriasis vulgaris, hence the importance of patient education.
