DESCRIPTION (provided by applicant): Psoriasis and the risk of diabetes Psoriasis affects over 7 million people in the US (125 million people worldwide) and is the most common helper T-cell (Th)-1 and Th-17 mediated inflammatory disease in humans. Epidemiological studies indicate that psoriasis is associated with an increased risk for major cardiovascular (CV) events and premature death due to CV disease independent of traditional risk factors. Emerging data suggest that patients with psoriasis may also be at increased risk for developing diabetes as well. The chronic inflammatory pathways involved in the maintenance of psoriasis have been shown to promote insulin resistance in animal and human models of diabetes. Furthermore, psoriasis and diabetes share susceptibility genes (such as CDKAL1). These shared genetic and inflammatory pathways suggest biologic plausibility for an increased risk of diabetes in patients with psoriasis. However, it is not known how clinical aspects of psoriasis (such as body surface area of involvement, anatomic sites of involvement, etc) impact diabetes risk nor is it known if successful treatment of psoriasis will lower the risk of diabetes. We will address these key knowledge gaps by conducting new aims to ongoing NIH funded projects. First, we will determine the risk of diabetes in a large population-based cohort of 9000 patients with psoriasis called the incident health outcomes and psoriasis events (iHOPE) study, established by R01 HL089744. Second we will determine how clinical aspects of psoriasis are associated with prevalent diabetes in a United States multi-centered clinic-based cohort of 1800 extensively phenotyped patients with psoriasis, 200 of whom have prevalent diabetes. This cohort was derived from the Dermatology Clinical Effectiveness Research Network (DCERN) established by RC1 AR058204. Third, we will determine if treatment of psoriasis with a systemic TNF-inhibitor (adalimumab) improves novel biomarkers which predict future development of diabetes compared to skin targeted treatment (ultraviolet B phototherapy) or placebo. This new aim will be investigated in the ongoing Vascular Inflammation in Psoriasis (VIP) trial funded by R01 HL111293, which is designed to evaluate vascular inflammation and lipid metabolism outcomes. These projects leverage existing studies conducted by the applicant to develop highly significant and innovative aims which will: 1) provide added value to ongoing studies while aiding the applicant to develop new skills in epidemiological and translational research focusing on diabetes; 2) address an important problem by determining which patients with psoriasis are at highest risk for developing diabetes thus warranting preventive interventions already proven to reduce the risk of diabetes; 3) determine if a class of medicines (i.e., TNF inhibitors) which are commonly used across multiple inflammatory disease indications hold promise for diabetes prevention through the study of innovative biomarkers in a rigorous randomized controlled trial which may yield new clinical practice paradigms; and, 4) provide a diverse clinical research platform in which to mentor young physician scientists in patient oriented research and promote their successful transition to independence.

描述（由申请人提供）：银屑病和糖尿病的风险银屑病影响美国超过700万人（全球1.25亿人），是人类最常见的辅助T细胞（Th）-1和Th-17介导的炎性疾病。流行病学研究表明，银屑病与重大心血管（CV）事件和CV疾病导致的过早死亡的风险增加相关，与传统风险因素无关。新出现的数据表明，银屑病患者也可能增加患糖尿病的风险。参与银屑病维持的慢性炎症途径已被证明会促进糖尿病动物和人类模型的胰岛素抵抗。此外，银屑病和糖尿病共享易感基因（如CDKAL 1）。这些共同的遗传和炎症途径表明银屑病患者糖尿病风险增加的生物学可接受性。然而，尚不清楚银屑病的临床方面（如受累的体表面积、受累的解剖部位等）如何影响糖尿病风险，也不清楚银屑病的成功治疗是否会降低糖尿病风险。我们将通过对正在进行的NIH资助项目进行新的目标来解决这些关键的知识差距。首先，我们将确定由R 01 HL 089744建立的一项名为偶发健康结局和银屑病事件（iHOPE）研究的9000例银屑病患者的大型人群队列中的糖尿病风险。其次，我们将确定银屑病的临床方面是如何与美国多中心临床为基础的队列广泛表型银屑病患者1800例，其中200人有糖尿病流行的糖尿病。该队列来源于RC 1 AR 058204建立的皮肤病临床有效性研究网络（DCERN）。第三，我们将确定与皮肤靶向治疗（紫外线B光疗）或安慰剂相比，全身性TNF抑制剂（阿达木单抗）治疗银屑病是否改善了预测未来糖尿病发展的新生物标志物。这一新目标将在正在进行的由R 01 HL 111293资助的血管炎症（VIP）试验中进行研究，该试验旨在评价血管炎症和脂质代谢结局。这些项目利用申请人进行的现有研究来开发高度重要和创新的目标，这些目标将：1）为正在进行的研究提供附加值，同时帮助申请人开发以糖尿病为重点的流行病学和转化研究的新技能;（二）通过确定哪些银屑病患者患糖尿病的风险最高，从而解决一个重要问题，降低患糖尿病的风险; 3）确定一类药物（即，TNF抑制剂），通常用于多种炎症性疾病适应症，通过在严格的随机对照试验中研究创新的生物标志物，有望预防糖尿病，这可能会产生新的临床实践范例;以及，4）提供多样化的临床研究平台，指导年轻的医生科学家进行以患者为导向的研究，并促进他们成功过渡到独立。
