An observational study of Lipedema, run by Kanuni Sultan Suleyman Training and Research Hospital.
Trial summary
Lipedema is a chronic and progressive adipose tissue disorder characterized by symmetrical fat accumulation, pain, tenderness, and easy bruising, predominantly affecting women. Increasing evidence suggests that chronic low-grade inflammation and impaired resolution of inflammation may contribute to its… Read more about this study

Study population: The study population will consist of adult women aged 18 to 65 years recruited from the Physical Medicine and Rehabilitation outpatient clinic of a tertiary care hospital. Participants will be classified into three groups: (1) women with clinically diagnosed lipedema, (2) women with obesity (body mass index ≥30 kg/m²) without lipedema, and (3) healthy female volunteers without chronic or inflammatory diseases. A total of 84 participants are planned to be enrolled, with 28 individuals in each group. The study aims to compare serum Maresin-1 levels and their associations with clinical and inflammatory parameters across these populations.
Who may be able to join
- Female participants aged 18 to 65 years. Women with a clinical diagnosis of lipedema for the lipedema group. Women with obesity (body mass index ≥30 kg/m²) and without a diagnosis of lipedema for the obesity group.
- Healthy female volunteers without chronic or inflammatory diseases for the healthy control group.
- No acute infection within the previous 3 months. Ability and willingness to provide written informed consent.
Who cannot join
- Active infection at the time of enrollment. History of autoimmune or chronic inflammatory disease. History of malignancy. Pregnancy or breastfeeding. Current use of corticosteroids or immunosuppressive medications. Regular use of anti-inflammatory medications that may affect inflammatory biomarkers.

About this study
Official title: Evaluation of the Relationship Between Serum Maresin-1 Levels and Clinical and Inflammatory Parameters in Patients With Lipedema
Lipedema is a chronic and progressive adipose tissue disorder characterized by symmetrical fat accumulation, pain, tenderness, and easy bruising, predominantly affecting women. Increasing evidence suggests that chronic low-grade inflammation and impaired resolution of inflammation may contribute to its pathophysiology. Maresin-1 is a specialized pro-resolving lipid mediator with potent anti-inflammatory and tissue-protective properties; however, its role in lipedema remains largely unknown. This cross-sectional observational study aims to evaluate serum Maresin-1 levels in women with lipedema and to investigate their associations with pain severity, inflammatory markers, central sensitization, and quality of life. Serum Maresin-1 levels and clinical characteristics will be compared among women with lipedema, obese women without lipedema, and healthy controls to explore the potential value of Maresin-1 as a biomarker in lipedema.
Read the detailed description
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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Lipedema | Women with clinically diagnosed lipedema. | |
| Obesity | Women with obesity (BMI ≥30 kg/m²) without clinical lipedema. | |
| Healthy Control | Healthy women without lipedema or obesity and without chronic inflammatory disease. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Serum Maresin-1 Level
The primary outcome is the serum Maresin-1 concentration measured in peripheral venous blood samples using a commercially available enzyme-linked immunosorbent assay (ELISA). Serum Maresin-1 levels will be compared among women with lipedema, obese women without lipedema, and healthy controls.
Measured: At baseline (single assessment during study participation)
Secondary outcomes (2)
Pain Severity (Visual Analog Scale, VAS)
Pain intensity will be assessed using the 10-cm Visual Analog Scale (VAS). Higher scores indicate greater pain severity.
Measured: At baseline (single assessment during study participation)
Central Sensitization Inventory (CSI) Score
Central sensitization symptoms will be evaluated using the Central Sensitization Inventory (CSI). Higher scores indicate greater central sensitization.
Measured: At baseline (single assessment during study participation)
