Clinical Significance of Infection on Psoriasis Severity.

The aim of the study was to appraise the link between psoriasis and , investigate the influence of treatment on psoriasis severity, determine the cutoff value of haptoglobin as a psoriatic biomarker, and determine the most reliable predictor for psoriasis in patients with . This study was carried out on 100 adult Saudi participants from the Security Forces Hospital (Riyadh, Kingdom of Saudi Arabia). All participants were allocated into 5 groups (20/group): controls (G1), psoriatic patients (G2), patients with (G3), psoriatic patients with untreated (G4), and psoriatic patients with treated (G5). The study was approved by the ethics committee of Security Forces Hospital, Riyadh, Saudi Arabia. The psoriasis area and severity index (PASI) score, C-urea breath test (C-UBT), C-reactive protein (CRP), haptoglobin, platelet P-selectin, cluster of differentiation 4/cluster of differentiation 8 (CD4/CD8) ratio, and lymphocyte percentages were recorded. The haptoglobin level was significantly elevated in psoriatic patients compared with G1. In G5, there was significant attenuation in the PASI score, P-selectin, CRP, CD4/CD8 ratio, and lymphocyte percentage compared with G4. There was a significant positive correlation between psoriasis severity and C-UBT. In addition, C-UBT and PASI scores were significantly positively correlated with CRP, platelet P-selectin, and percentage of lymphocytes. plays a potential role in psoriasis pathogenesis. treatment attenuates psoriasis severity. Haptoglobin could be utilized as a psoriatic biomarker with 1.95 g/L as the cutoff value. The most reliable predictor for psoriasis in infected patients with is C-UBT.
