Both Type 1 and Type 2 diabetes is often prevalent within the same family. Can these partially same heridatory factors be on the background of both of these diabetes types?
In 2002 we started to recruit, with the help of newspaper adds, families that have members with both Type 1 and Type 2 diabetes (=mix-families). The Type 2 diabetes patients of these families weree carefylly examined to study their insulin production, insulin sensibility and diabetes complications. I addition, carotid artery calcification was measured using ultrasound (caroticultrasound). The patients examined again after 3 years on a follow-up visit.
