Can Serum Lumican Level Identify a Hidden Fragility Phenotype Beyond Bone Mineral Density in Postmenopausal Women? (LUMINOS)
24. juni 2026 opdateret af: Dilek ün oguzhanasilturk, Kanuni Sultan Suleyman Training and Research Hospital
Osteoporosis is a major cause of morbidity and fragility fractures in postmenopausal women.
Bone mineral density (BMD) alone may not fully reflect fracture risk and skeletal fragility.
Lumican, an extracellular matrix proteoglycan involved in collagen organization and musculoskeletal tissue homeostasis, has emerged as a potential biomarker for bone health.
This prospective observational study aims to investigate the relationship between serum lumican levels, bone mineral density, muscle strength, and clinical fragility indicators in postmenopausal women.
Approximately 100 participants will undergo routine osteoporosis assessment including DEXA, laboratory testing, FRAX evaluation, and handgrip strength measurement.
The study will evaluate whether serum lumican levels can identify a hidden fragility phenotype beyond conventional bone mineral density measurements.

Detaljeret beskrivelse
This is a prospective, observational, single-center clinical study designed to evaluate serum lumican levels in postmenopausal women undergoing routine osteoporosis assessment.
The study will investigate the association of lumican with bone mineral density, handgrip strength, FRAX-based fracture risk, history of falls, and fragility fracture history.
No treatment or interventional procedure will be applied.
Serum lumican will be measured from venous blood samples, and all other clinical and laboratory data will be collected as part of standard osteoporosis evaluation.
The study aims to explore whether lumican may contribute to the identification of fragility risk beyond conventional bone mineral density measurements.
