Abstract

Psoriasis is a chronic inflammatory skin condition that is often associated with various comorbidities, including cardiovascular disease, obesity, diabetes mellitus, and psoriatic arthritis. Obesity, particularly abdominal obesity, is known to impact the effectiveness of psoriasis treatment. This study aims to explore the relationship between abdominal circumference and the incidence of psoriasis in patients at the Dermatology and Venereology Polyclinic of Dr. Moewardi Hospital, Surakarta. The objective of this research was to determine whether abdominal circumference (waist circumference) is associated with the incidence of psoriasis in patients at the Dermatology and Venereology Polyclinic. A cross-sectional study was conducted with 30 psoriasis vulgaris patients treated at the clinic from July to August 2024. Waist circumference was categorized as high or normal. Data analysis was performed using the Mann-Whitney test and logistic regression analysis. The majority of participants (70%) had high waist circumference. Statistically, only age showed a significant relationship with psoriasis incidence (p = 0.015). Gender, BMI status, and waist circumference did not significantly correlate with psoriasis incidence (p = 0.069, p = 0.789, p = 0.284, respectively). This study suggests that waist circumference does not have a significant relationship with the incidence of psoriasis. Future research could explore other factors contributing to psoriasis exacerbation, such as metabolic syndrome or visceral adiposity.

Abstract

Acne vulgaris (AV) is an inflammatory skin disorder with multifactorial pathogenesis involving genetics, hormones, and immune dysregulation. Interleukin-21 (IL-21), a pleiotropic cytokine mainly secreted by T follicular helper and Th17 cells, has been implicated in various inflammatory skin diseases. However, its role in AV remains unclear. This cross-sectional study included 46 patients with AV, classified into mild (n=19), moderate (n=16), and severe (n=11) groups. Serum IL-21 levels were measured using an enzyme-linked immunosorbent assay (ELISA). Baseline characteristics were compared across groups, and interobserver reliability of AV severity grading was evaluated using Cohen’s kappa test. One-way ANOVA was applied to assess differences in IL-21 levels among severity groups, with a significance level set at p<0.05. The mean serum IL-21 level was highest in the severe AV group (303.53 pg/mL), followed by the moderate (223.7 pg/mL) and mild (213.2 pg/mL) groups. Although there was a trend toward increasing IL-21 levels with higher AV severity, statistical analysis revealed no significant difference among the three groups (p=0.130). Serum IL-21 levels were elevated in AV patients compared with previously reported healthy controls but did not differ significantly across severity levels. These findings suggest that IL-21 may play a role in the pathophysiology of AV, though it is not a reliable marker of clinical severity. Further case-control and tissue-based studies are needed to clarify its role.
