Abstract
Aim: To evaluate the combined predictive value of serum neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and macular neovascularization (MNV) characteristics for treatment efficacy in neovascular age-related macular degeneration (nAMD) patients receiving anti-VEGF plus glucocorticoid therapy.
Patients and methods: This retrospective study included 145 patients (153 eyes) with nAMD receiving conbercept combined with dexamethasone implant. Patients were categorized as Inactive (n = 89) or Active (n = 64) based on post-treatment MNV activity. Baseline NLR, PLR, and MNV morphology were assessed. Multivariate logistic regression identified independent predictors, and ROC analyses evaluated predictive value.
Results: Patients with persistent MNV activity showed significantly higher baseline NLR, PLR, MNV area, and fractal dimension (all p < 0.001). Multivariate analysis identified baseline visual acuity, MNV type, fluid volumes, MNV morphological parameters, and inflammatory markers as independent predictors. The combined model incorporating inflammatory markers and MNV characteristics demonstrated superior performance (AUC = 0.92, 95% CI: 0.87-0.96) with 79.69% sensitivity and 91.01% specificity.
Conclusion: Combining serum inflammatory markers with MNV morphological characteristics enhanced predictive value for treatment response in nAMD patients receiving combination therapy. This integrated approach may facilitate personalized treatment strategies in nAMD management.
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.
