Abstract

The co-morbidity of psoriasis (PsO) and metabolic syndrome (MetS) is prevalent. While the mechanisms causing PsO in MetS remain unknown, it is understood that gut microbiota plays a critical role in maintaining immune and metabolic balance. However, the specific mechanisms and whether biomarkers are involved in the pathophysiological process of PSO in MetS patients have yet to be elucidated. This study involved 29 patients with PSO and MetS (PM) and 29 with MetS (M). It analyzed their clinical parameters, microbial composition, function, diagnostic, and predictive performance. The results unveiled significant differences between the two groups concerning microbial diversity and community composition. Most of the differential microbiota in the PM group exhibited a negative correlation with high-density lipoprotein (HDL) and a positive correlation with serum uric acid (SUA). In contrast, the opposite was observed in the M group. Sixteen MetaCyc pathways showed significance in the PM group, encompassing peptidoglycan biosynthesis II (staphylococci), the super pathway of L-arginine and L-ornithine degradation, teichoic acid (poly-glycerol) biosynthesis, and palmitic biosynthesis II (bacteria and plants). Six KEGG pathways were enriched in the M group, such as flavone, flavonol biosynthesis, and carotenoid biosynthesis. Most importantly, we determined that eight biomarkers, represented by Akkermansia, demonstrated robust diagnostic predictive power. This study elucidates the potential mechanism through which metabolic disorders impact the onset and progression of psoriasis via intestinal microbiota. Furthermore, it offers novel strategies for preventing, diagnosing, and treating PsO in MetS.

银屑病合并代谢综合征患者肠道菌群特征分析。
牛皮癣(PsO)和代谢综合征(MetS)的合并症是普遍的。虽然在MetS中引起PsO的机制尚不清楚,但肠道微生物群在维持免疫和代谢平衡中起着关键作用。然而,其具体机制以及生物标志物是否参与MetS患者PSO的病理生理过程尚不清楚。本研究纳入29例PSO合并MetS (PM)和29例MetS (M)患者。分析了它们的临床参数、微生物组成、功能、诊断和预测性能。结果表明,两组在微生物多样性和群落组成方面存在显著差异。PM组大多数差异菌群与高密度脂蛋白(HDL)呈负相关,与血清尿酸(SUA)呈正相关。而M组则相反。16条MetaCyc途径在PM组中表现出显著性,包括肽聚糖生物合成II(葡萄球菌)、l -精氨酸和l -鸟氨酸降解超级途径、苔藻酸(聚甘油)生物合成和棕榈生物合成II(细菌和植物)。M组富集了黄酮、黄酮醇生物合成、类胡萝卜素等6条KEGG通路。最重要的是,我们确定了以Akkermansia为代表的八种生物标志物,显示出强大的诊断预测能力。本研究阐明了代谢紊乱通过肠道菌群影响牛皮癣发病和进展的潜在机制。此外,它为met的PsO的预防、诊断和治疗提供了新的策略。
