Abstract

Psoriasis is a chronic, immune-mediated disorder that results from a polygenic predisposition. Nitric oxide (NO) has been considered as important factors in the pathogenesis of psoriasis. This study aims to determine the correlation of serum NO levels with the type and severity of psoriasis. This cross-sectional study was conducted from May to September 2018. Difference in the average of serum NO levels in psoriasis patients with control groups is analyzed using t-test. The Spearman correlation test was used to see the correlation of serum NO levels with type and severity of psoriasis measured by Psoriasis Area and Severity Index (PASI) score. There was significant difference between serum NO level in the control group compared to the group of psoriasis patients (p=0.037). Patient with generalized pustular psoriasis has the highest mean of NO level (59.07 µmol/L). There was no significant correlation between serum NO level with type (r=0.008, p=0.9710 and severity (r=0.157, p=0.486) of psoriasis. Nitric oxide levels are elevated in psoriasis patients, which indicate that oxidative stress plays an important role in the etiopathogenesis of psoriasis.

Abstract

Psoriasis belongs to erythrosquamous dermatosis with uncertain etiology. Nitric oxide (NO) that acts as growth and differentiation regulator of keratinocytes is thought to play an important role in the pathogenesis of this disease. This study was aimed to determine the difference of nitric oxide serum level with the severity and duration of psoriasis patients. A cross-sectional study was conducted in 22 subjects with psoriasis vulgaris in the outpatient clinic of Dr. Moewardi Hospital Surakarta from May-September 2018 with 22 healthy individuals as control group. The severity of psoriasis was assessed using psoriasis area severity index (PASI), and serum NO is measured using Greiss method. Data then analysed using T-test and Kruskal Wallis tests (p<0.05). There was a significant difference in serum NO between the psoriasis patients and control group (p=0.020); there was no significant difference between serum NO patients and PASI score and duration of disease. It can be concluded that NO is an important factor in the inflammatory process in psoriasis, especially in active lesion.
