Hereditary haemorrhagic telangiectasia is a genetic disease, causing abnormal formations of blood vessels in skin, mucus membranes, lungs, liver, and brain. In the liver, the disease results in shunting of blood, bypassing the capillary bed. Recent studies have shown that the prevalence of liver shunts are more frequent than previously suggested.

Fibulin-1 is a marker for arterial extracellular matrix alterations in type 2 diabetes.

Background: Extracellular matrix alterations are important elements in the arterial changes seen in diabetes, being associated with increased vascular stiffness and the development of cardiovascular diseases. However, no biomarkers for diabetes-related arterial changes have been defined.

Methods: Mammary artery specimens from 17 men with type 2 diabetes and 18 nondiabetic individuals were used for microarray expression profiling, quantitative real-time PCR, immunoassay, and immunohistochemical analyses.
