Leiba et al¹ recently suggested that hyperlipidaemia, particularly hypertriglyceridaemia, may be a risk factor for thrombosis in Behçet’s disease. Published studies suggest an association between increased levels of plasma lipids and deep-vein thrombosis,^2–4 although the pathogenic mechanism is controversial. In an ongoing study on the association between thrombophilic defects and thrombotic events in patients with Behçet’s disease, we have also evaluated the possible contribution of plasma lipids to the genesis of thrombotic events in these patients. We conducted a case–control study in patients with Behçet’s disease recruited from the records of the La Fe, General and Peset University Hospitals …
