Abstract

Aim: Anemia of inflammation (AI) is common among patients with diabetic foot ulcers (DFU). This study aimed to investigate the specific relationship between inflammation indicators and anemia in patients with DFU.Materials & methods: This cross-sectional study was carried out among patients with DFU between 2018 and 2023. Clinical data were gathered before treatment. Restricted cubic spline regression was employed to investigate the non-linear associations between inflammation and anemia.Results: A total of 395 patients with Wagner grades 2-4 were enrolled in the study. About 63.54% of the patients with DFU had anemia which was primarily presented with normocytic hypopigmentation anemia. Elevated IL-6 levels (39.10-369 pg/ml) were significantly associated with an increased likelihood of anemia (OR = 4.84; 95% CI: 1.97-11.90). Similarly, high CRP levels (48.56-385 mg/l) were linked to a higher prevalence of anemia (OR = 5.01; 95% CI: 2.35-10.68). Furthermore, a nonlinear relationship was observed between CRP levels and anemia, suggesting that CRP values exceeding 53.889 mg/l may trigger anemia in patients with diabetic foot ulcers.Conclusion: Inflammation is identified as an independent risk factor for AI in patients with DFU. The inflammation indicators (CRP and IL-6) and anemia exhibit an L-shaped nonlinear correlation in patients with DFU.

糖尿病足溃疡患者的炎症指标与贫血之间的关系。

目的：炎症性贫血（AI）在糖尿病足溃疡（DFU）患者中很常见。本研究旨在探讨DFU患者炎症指标与贫血之间的具体关系：这项横断面研究在2018年至2023年间的DFU患者中开展。收集了治疗前的临床数据。采用限制立方样条回归法研究炎症与贫血之间的非线性关联：共有 395 名瓦格纳 2-4 级患者参与研究。约63.54%的DFU患者患有贫血，主要表现为正常红细胞减少性贫血。IL-6水平升高（39.10-369 pg/ml）与贫血的可能性增加显著相关（OR = 4.84；95% CI：1.97-11.90）。同样，高 CRP 水平（48.56-385 毫克/升）也与贫血发生率较高有关（OR = 5.01；95% CI：2.35-10.68）。此外，还观察到 CRP 水平与贫血之间存在非线性关系，这表明 CRP 值超过 53.889 毫克/升可能会引发糖尿病足溃疡患者贫血：结论：炎症是导致糖尿病足溃疡患者贫血的独立风险因素。在 DFU 患者中，炎症指标（CRP 和 IL-6）与贫血呈 L 型非线性相关。

期刊介绍： Biomarkers are physical, functional or biochemical indicators of physiological or disease processes. These key indicators can provide vital information in determining disease prognosis, in predicting of response to therapies, adverse events and drug interactions, and in establishing baseline risk. The explosion of interest in biomarker research is driving the development of new predictive, diagnostic and prognostic products in modern medical practice, and biomarkers are also playing an increasingly important role in the discovery and development of new drugs. For the full utility of biomarkers to be realized, we require greater understanding of disease mechanisms, and the interplay between disease mechanisms, therapeutic interventions and the proposed biomarkers. However, in attempting to evaluate the pros and cons of biomarkers systematically, we are moving into new, challenging territory. Biomarkers in Medicine (ISSN 1752-0363) is a peer-reviewed, rapid publication journal delivering commentary and analysis on the advances in our understanding of biomarkers and their potential and actual applications in medicine. The journal facilitates translation of our research knowledge into the clinic to increase the effectiveness of medical practice. As the scientific rationale and regulatory acceptance for biomarkers in medicine and in drug development become more fully established, Biomarkers in Medicine provides the platform for all players in this increasingly vital area to communicate and debate all issues relating to the potential utility and applications. Each issue includes a diversity of content to provide rounded coverage for the research professional. Articles include Guest Editorials, Interviews, Reviews, Research Articles, Perspectives, Priority Paper Evaluations, Special Reports, Case Reports, Conference Reports and Company Profiles. Review coverage is divided into themed sections according to area of therapeutic utility with some issues including themed sections on an area of topical interest. Biomarkers in Medicine provides a platform for commentary and debate for all professionals with an interest in the identification of biomarkers, elucidation of their role and formalization and approval of their application in modern medicine. The audience for Biomarkers in Medicine includes academic and industrial researchers, clinicians, pathologists, clinical chemists and regulatory professionals.
