Both health-related and general life satisfaction is compromised in IBD outpatients, and health-related topics have major impact. Not surprisingly, inflammatory activity compromises QOL, which underlines the importance of anti-inflammatory strategies. The importance attributed to health-related features is higher in IBD patients than in the normal population.

Patients with CAD and the ACE DD genotype have a significantly higher incidence and greater extent of coronary lesion calcification, as determined by IVUS. This finding indicates that the ACE I/D gene polymorphism is related to the development or progression of atherosclerotic plaque calcification.

HCC and ICC differ to some extent in their CEUS enhancement pattern. Incomplete arterial hyperenhancement is more often seen in ICC than in HCC. A rim sign seems to be specific for ICC, but is only rarely present. However, in a case-to-case decision, due to overlapping characteristics, a reliable differentiation between the two tumor types by CEUS alone is very often not possible.

Our results suggest a relationship between the prevalence of hypertension and the deletion polymorphism of the ACE gene in young type 1 diabetic patients, but we could not find an association between carotid artery IMT and ACE genotype in this population.

The insertion/deletion (I/D) polymorphism of the angiotensin-converting-enzyme (ACE) gene has been reported to be associated with diabetic nephropathy in IDDM. We studied the relationship between this polymorphism and diabetic nephropathy in 210 IDDM patients. Their DNA was analyzed by polymerase chain reaction to type for the presence (I) or absence (D) of the 287 bp fragment in intron 16 of the ACE gene. The relative frequency of the different genotypes was 33.8% (DD), 43.8% (ID), and 22.4% (II). There were no significant differences between the genotypes in age, body-mass-index, blood pressure, plasma total cholesterol and triglycerides. The prevalence of microalbuminuria or nephropathy was 23.9% in the DD, 16.3% in the ID, and 17% in the II genotypes. The higher percentage of microalbuminuria or nephropathy in the DD genotypes was due to an increasing frequency of DD genotypes in the IDDM patients with long diabetes duration. After matching for diabetic retinopathy, gender, and diabetes duration, there was no association between the ACEI/D polymorphism and diabetic nephropathy. In conclusion, these results suggest that the ACE DD genotype cannot be regarded as a risk factor for diabetic nephropathy, but may even be associated with diabetes duration and thus longevity in IDDM patients.
