Genetic and environmental factors are associated with its etiology. Recently systemic immune inflammatory index, has been proposed as a biomarker for prognosis and severity prediction. Although it has been studied in psoriasis in general, no study exists for its association with the individual types of psoriasis. This study thus aimed to determine its association with clinical characteristics of psoriasis subtypes. Materials and Methods: Data were retrospectively retrieved from the hospital electronic medical database from January 2020 to August 2022. Only patients with CBC results were included. Clinical data retrieved were: Patients’ age, gender, type of psoriasis diagnosed, body mass index, duration of the disease, family history of psoriasis, history of smoking, diabetes, and hypertension records. Laboratory data retrieved were: Complete blood count (CBC), C-reactive protein, Immunoglobulin E (IgE), Total cholesterol, Triglycerides and Low-density lipoprotein cholesterol. Data were analyzed in SPSS and GraphPad prism. Results: The study enrolled 85 patients with psoriasis;56.47% males, and 43.53% females. 7.6% had psoriasis for less than 10 years, while 42.4% had the disease for more than 10 years. Psoriasis vulgaris was the most common diagnosis, 41.2%, followed by p. pustular, 30.6% and then p. erythroderma 28.2%. Mean age ± SD of the p. vulgaris, p. pustular and p. erythroderma patients were 47.3 ± 15.3;45.3 ± 14.6, and 57.1 ± 11.7 respectively. SII was significantly higher in p. pustular than the rest, (p Conclusion: In summary, systemic immune inflammatory index (SII) was significantly higher in psoriasis pustular than other subtypes of psoriasis, and had an association with hypertension in psoriasis pustular patients. These findings suggest a possible association between SII and psoriasis pustular that should be investigated in an independent study.展开更多

Generalized pustular psoriasis （GPP） is the severe and rare type of psoriasis. The association between tumor necrosis factor-alpha induced protein 3 interacting protein 1 （TNIP1） gene and psoriasis was confirmed in people with multiple ethnicities. This study was to investigate the association between TNIP1 gene polymorphisms and pustular psoriasis in Chinese Hart population. Methods： Seventy-three patients with GPP, 67 patients with palmoplantar pustulosis （PPP）, and 476 healthy controls were collected from Chinese Hart population. Six single nucleotide polymorphisms （SNPs） of the TNIP1 gene, namely rs3805435, rs3792798, rs3792797, rs869976, rs 17728338, and rs999011 were genotyped by using polymerase chain reaction-ligase detection reaction. Statistical analyses were performed using the PLINK 1.07 package. Allele frequencies and genotyping frequencies for six SNPs were compared by using Chi-square test, odd ratio （OR） （including 95% confidence interval） were calculated. The haplotype analysis was conducted by Haploview software. Results： The frequencies of alleles of five SNPs were significantly different between the GPP group and the control group （P ≤ 7.22 × 10^-3）, especially in the GPP patients without psoriasis vulgaris （PsV）. In the haplotype analysis, the most significantly different haplotype was H4： ACGAAC, with 13.1% frequency in the GPP group but only 3.4% in the control group （OR = 4.16, P = 4.459 × 10^-7）. However, no significant difference in the allele frequencies was found between the PPP group and control group for each of the six SNPs （P 〉 0.05）. Conclusions： Polymorphisms in TNIP1 are associated with GPP in Chinese Han population. However, no association with PPP was found. These findings suggest that TNIPI might be a susceptibility gene for GPE展开更多
