ABSTRACT
Objective:To investigate correlations between blood lipid levels and clinical characteristics of patients with psoriasis vulgaris (PsV) in Fujian province.Methods:Totally, 245 PsV patients were enrolled from Department of Dermatology of the First Affiliated Hospital of Fujian Medical University from March 2019 to March 2022, and 250 gender-, age-, and body mass index-matched health checkup examinees served as controls. Their biochemical indicators, such as blood lipids, liver function, and kidney function, were evaluated. Clinical data, such as disease courses, involvement of specific sites, history of smoking and alcohol consumption, and family history of psoriasis, were collected from the PsV patients, and correlations between these clinical data and dyslipidemia were analyzed. Measurement data were compared using t test or Mann-Whitney U test, and enumeration data were compared using chi-square test. Results:There were 122 (50.8%) patients with dyslipidemia in the PsV group and 94 (37.6%) in the control group, and the prevalence of dyslipidemia significantly differed between the two groups ( χ2 = 7.48, P = 0.006). The prevalence of hypo-high-density lipoprotein cholesterolemia was significantly higher in the PsV group (29.8%) than in the control group (18.8%; χ2 = 8.15, P = 0.004). The PsV group showed significantly decreased serum levels of total cholesterol (4.5[3.9, 5.2] mmol/L), high-density-lipoprotein cholesterol (1.1[1.0, 1.3] mmol/L), and apolipoprotein A1 (1.2[1.1, 1.4] g/L) compared with the control group (4.9[4.3, 5.4] mmol/L, 1.3[1.1, 1.5] mmol/L, 1.3[1.2, 1.5] g/L, respectively; all P < 0.001). The proportions of males, patients with a history of alcohol consumption, and patients with involvement of the palmoplantar sites were significantly higher in the PsV patients with dyslipidemia (92.6%, 13.1%, 13.8%, respectively) than in those without dyslipidemia (70.7%, 6.0%, 5.0%, respectively; all P < 0.001). Multifactorial logistic regression analysis showed that "male" and "BMI ≥ 25 kg/m 2" were independent risk factors for dyslipidemia in the PsV patients ( OR [95% CI]: 3.94 [1.74, 9.74], 3.18 [1.71, 6.09], respectively), and "involvement of the palmoplantar sites" was independently associated with increased risk of hyperlipidemia ( OR [95% CI]: 3.38 [1.18, 11.01]) . Conclusion:The prevalence of dyslipidemia was higher in PsV patients than in healthy populations, and PsV patients being males, having BMI ≥ 25 kg/m 2 and with involvement of palmoplantar sites may be prone to develop lipid metabolism disorders.
