Background Psoriasis is a chronic systemic inflammatory disease frequently associated with serious comorbidities. Objectives To investigate the systemic inflammatory burden in psoriasis and to assess the correlation between traditional and novel inflammatory markers and the severity of the disease. Methods This cross-sectional study was conducted on 60 patients with psoriasis vulgaris and 50 healthy volunteers. Data including demographics, Psoriasis Area and Severity Index scores, and laboratory results were analyzed and compared. Results Compared with the control group, the psoriatic patients had significantly higher high sensitive C-reactive protein, serum amyloid A, erythrocyte sedimentation rate, leukocyte, neutrophil, neutrophil-to-lymphocyte ratio, monocyte to high density lipoprotein (HDL) cholesterol ratio, and aspartate aminotransferase levels, and significantly lower HDL cholesterol levels (p < 0.05). No significant difference was found in procalcitonin, lymphocyte, monocyte, hemoglobin, red blood cell distribution width, platelet, mean platelet volume, platelet distribution width, lymphocyte-to-monocyte ratio, anti-cyclic citrullinated peptide, glucose, alanine aminotransaminase, blood urea nitrogen, creatinine, triglyceride, total cholesterol, and LDL cholesterol levels between the two groups (p > 0.05). The Psoriasis Area and Severity Index score was positively correlated with high-sensitivity C-reactive protein, serum amyloid A, and monocyte to HDL cholesterol ratio, and negatively correlated with lymphocyte-to-monocyte ratio (p < 0.05). Study limitations This was a single-center study with relatively limited numbers of patients and controls. Conclusions The data show that high sensitivity C-reactive protein, serum amyloid A, erythrocyte sedimentation rate, neutrophil-to-lymphocyte ratio, and monocyte to HDL cholesterol ratio can be used as markers of systemic inflammation in patients with psoriasis. Moreover, high sensitivity C-reactive protein, serum amyloid A, monocyte to HDL cholesterol ratio and lymphocyte-to-monocyte ratio are closely related to the Psoriasis Area and Severity Index score, and they may be regarded as objective indicators in determining the disease severity.

Introduction Psoriasis is a chronic inflammatory skin disease characterized by papules and/or plaques that are often covered with silvery-whitish scales [1]. The presence of a family history of psoriasis in about 30% of patients, simultaneous presence of psoriasis in monozygotic twins, and association of early-onset psoriasis with many major tissue antigen alleles, especially human leukocyte antigen (HLA) Cw6, are some of the factors that suggest a role for genetic factors in the occurrence of the disease [2,3]. Although the pathogenesis of psoriasis is not known exactly, dysregulation in T cells is thought to induce keratinocyte proliferation. Studies have shown a prominent role of the helper T-cell (Th) 17/interleukin (IL)-23 pathway in the pathogenesis of psoriasis [4,5]. IL-23 is the key cytokine that directs naive CD 4+ T cells to differentiate into Th17 cells by upregulating the IL-23 receptor (IL-23R) on naive T cells, resulting in the secretion of cytokines [4,5]. Previous studies have shown a significant relationship between psoriasis and some polymorphisms in the IL-23R gene [6,7]. The IL-23R gene consists of 11 exons and 10 introns; it is localized in chromosome 1p31.3 and is 2912 bp long (Figure). The rs2201841, rs11209026, rs11465804, rs7530511, and rs1343152 polymorphisms are located in the 7th intron, 9th exon, 8th intron, 7th exon, and 8th intron, respectively. Our study is the first to investigate the relationship between IL-23R gene polymorphisms and psoriasis in Turkey. Additionally, our study is the first in the literature Background/aim: IL-23R gene polymorphisms and the association of these polymorphisms with serum IL-23 levels were investigated in patients with psoriasis in the current study. Materials and methods: Sixty-seven patients with psoriasis who were admitted to our dermatology outpatient clinic and 67 healthy controls were included in the study. Polymorphisms of the IL-23R gene were determined by KASP-PCR method, and serum IL-23 levels were determined by ELISA method. Results: The distribution of IL-23R gene polymorphisms rs2201841, rs11209026, rs7530511, rs1343152, and rs11465804 was not significantly different in the patient and control groups. The AA genotype of the rs2201841 locus in males and the GA genotype in females, as well as the AA genotype of the rs1343152 locus in males and the CA genotype in females, were statistically significant in patients with psoriasis. The mean serum IL-23 level was significantly lower in the patient group (42.62 ± 5.96) compared to the control groups (75.76 ± 13.24). Conclusion: IL-23R gene polymorphisms including rs2201841, rs11209026, rs7530511, rs11465804, and rs1343152 were not found to be significantly related to psoriasis. Different genetic polymorphisms may play a role in the development of psoriasis in female and male populations. Ethnic differences between different populations may have led to differences in the distribution of polymorphisms in the current study with compared to other published studies. Additionally, many different ge...

Our findings suggest that there is an association of the MTHFR gene C677T polymorphism with the susceptibility of a person for development of AS. However, the IL-4 gene is not associated with AS within the same population.
