Atenolol Versus Losartan in the Prevention of Progressive Dilation of the Aorta in Marfan Syndrome

2014-08-27 03:12:50 | BioPortfolio

Summary

The purpose of this study is to evaluate the efficacy of Losartan versus Atenolol in the progression of aortic dilatation in patients with Marfan syndrome.

Description

Marfan syndrome is a genetic disease of the connective tissue. Patients with Marfan syndrome experience an expansion of the aorta that can lead to dissection or rupture of it. This is the main cause of mortality in these patients.

The main objective of this study is to evaluate the efficacy of Losartan versus Atenolol in the progression of aortic dilation in patients with Marfan syndrome.

The measurement is made by echocardiography, assessing the diameter of the aorta in different zones: valve annulus, sinuses of Valsalva, sinotubular junction, ascending aorta, aortic arch, thoracic and abdominal aorta.

A total number of 150 subjects diagnosed with Marfan syndrome and who meet the diagnostic criteria of Ghent, of both sexes, 75 per treatment group, aged between 5 and 60, will be included in the study. The study is being conducted in two Spanish hospitals.

The treatment is maintained throughout the study period.

Medical and Biotech [MESH] Definitions

An autosomal dominant disorder of CONNECTIVE TISSUE with abnormal features in the heart, the eye, and the skeleton. Cardiovascular manifestations include MITRAL VALVE PROLAPSE, dilation of the AORTA, and aortic dissection. Other features include lens displacement (ectopia lentis), disproportioned long limbs and enlarged DURA MATER (dural ectasia). Marfan syndrome is associated with mutations in the gene encoding fibrillin, a major element of extracellular microfibrils of connective tissue.

An autosomal dominant aneurysm with multisystem abnormalities caused by increased TGF-BETA signaling due to mutations in type I or II of TGF-BETA RECEPTOR. Additional craniofacial features include CLEFT PALATE; CRANIOSYNOSTOSIS; HYPERTELORISM; or bifid uvula. Phenotypes closely resemble MARFAN SYNDROME; Marfanoid craniosynostosis syndrome (Shprintzen-Goldberg syndrome); and EHLERS-DANLOS SYNDROME.

A fibrillin (FBN1) that functions as a structural support protein for MICROFIBRILS. It also regulates the maturation of OSTEOBLASTS by controlling the availability and concentration of TGF-BETA and BONE MORPHOGENETIC PROTEINS. Mutations in the FBN1 gene are associated with MARFAN SYNDROME.

A cardioselective beta-adrenergic blocker possessing properties and potency similar to PROPRANOLOL, but without a negative inotropic effect.

An antagonist of ANGIOTENSIN TYPE 1 RECEPTOR with antihypertensive activity due to the reduced pressor effect of ANGIOTENSIN II.
