Abstract | BACKGROUND: METHODS: Serum levels of osteopontin were quantified by means of sandwich immunoassay in 25 EDMD patients (10 laminopathies AD-EDMD and 15 emerinopathies--X-EDMD), eight carriers of X-EDMD, nine disease controls (patients with dystrophinopathy) and 20 age-matched healthy controls. RESULTS: The levels of circulating OPN were elevated in all AD-EDMD and X-linked EDMD patients, as well as in X-EDMD carriers and patients suffering progressive muscular dystrophy. There was no correlation between the osteopontin level and different cardiac parameters, including left-ventricular end-diastolic diameter, left atrial diameter, the left ventricular ejection fraction and the CK-MB level. There was a slight negative correlation with the ages of the patients. CONCLUSIONS: The presented results indicate that assessments of circulating OPN levels may help to identify EDMD patients at risk of dilated cardiomyopathy and might be therefore included among the set of biomarkers referred to with a view to appropriate early cardiologic diagnosis and therapy being commenced with in time.
