An interventional study of lipoprotein (a) in Lymphedema, sponsored by Centre Hospitalier Universitaire de Nice. Recruiting at 2 sites in France. Open to participants aged 18 Years to 99 Years. Per ClinicalTrials.gov, last updated 2026-08-31.

Lymphedema is a chronic disease that causes lymph to accumulate in the interstitial tissue. The lymphatic network is involved in the metabolism of lipids and lipoproteins, and this accumulation leads to lipid deposits in the tissues involved. The level of lipoprotein(a) [LP(a)] has been shown to be a cardiovascular risk factor, which is partly genetically determined and influenced by certain factors (chronic renal failure, statin treatment, sporting activity or a diet low in saturated fatty acids...). Plasma levels of LP(a) lipoproteins (a) are linearly associated with an increased risk of myocardial infarction and carotid and femoral vascular stenosis. We currently manage patients with primary or secondary lymphedema, whatever the etiology, in the vascular medicine and explorations unit at Nice University Hospital.
Those taking part in intensive inpatient decongestive therapy benefit from a blood test, in particular for lipids [total cholesterol, triglycerides, HDL and LDL cholesterol, apolipoproteins A and B and Lp(a)]. Our team observed an elevated Lp(a) level >30 mg/dL in 10 of the 17 patients in whom we carried out this test (whether or not dyslipidemia existed, and whether or not it was known or treated). This is a very high prevalence compared with the general population, in whom an increased level is found in 25% of patients.
In view of the impact of Lp(a) on cardiovascular risk and the involvement of the lymphatic system in lipoprotein metabolism, it seems essential to verify our preliminary results on a larger population. In this multicenter cross-sectional trial, we propose to perform Lp(a) lipoprotein assays in lymphedema patients to determine whether there is an increase in this marker in this pathological context. We will also study the concordance of this level with cardiovascular risk assessment scores such as SCORE2/SCORE2-OP and the coronary calcium score. We will look for factors influencing plasma LP(a) levels, both general factors suspected of playing a role and factors specific to lymphedema.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
