Serum Maresin-1 Levels in Patients With Lipedema: A Cross-Sectional Study (LIP-MARES)
Evaluation of the Relationship Between Serum Maresin-1 Levels and Clinical and Inflammatory Parameters in Patients With Lipedema

상세 설명
Lipedema is a chronic, progressive adipose tissue disorder that predominantly affects women and is characterized by symmetrical enlargement of the extremities, pain, tenderness, and easy bruising. Despite its increasing recognition, the underlying pathophysiological mechanisms remain incompletely understood. Current evidence suggests that adipose tissue dysfunction, microvascular alterations, and chronic low-grade inflammation may contribute to disease development and progression. Distinguishing lipedema from obesity and lymphedema remains a major clinical challenge, highlighting the need for reliable biological markers.
Maresin-1 is a macrophage-derived specialized pro-resolving lipid mediator involved in the active resolution of inflammation and the restoration of tissue homeostasis. Experimental and clinical studies have demonstrated its anti-inflammatory and immunomodulatory properties in several chronic inflammatory conditions. However, the relationship between circulating Maresin-1 levels and the clinical manifestations of lipedema has not been adequately investigated.
This study is designed as a single-center, cross-sectional, observational study including three groups: women with clinically diagnosed lipedema, obese women without lipedema, and healthy female controls. A total of 84 participants are planned to be enrolled, with 28 individuals in each group.
Serum Maresin-1 concentrations will be measured using the enzyme-linked immunosorbent assay (ELISA) method. Clinical assessments will include pain severity evaluated by the Visual Analog Scale (VAS), central sensitization assessed by the Central Sensitization Inventory (CSI), and health-related quality of life measured using the EuroQol-5D (EQ-5D). Routine inflammatory parameters, including C-reactive protein (CRP) and the neutrophil-to-lymphocyte ratio (NLR), will also be evaluated.
The primary objective of the study is to compare serum Maresin-1 levels among the three groups. Secondary objectives are to investigate the associations between Maresin-1 levels and pain severity, inflammatory parameters, central sensitization, and quality of life, as well as to explore the potential role of Maresin-1 as a biomarker for lipedema pathophysiology.
