Abstract

Background Both cardiovascular disease and liver disease are particularly common in people with type 2 diabetes and it is possible that the two conditions are inter-related. Non-invasive biomarkers are increasingly used to estimate liver inflammation and fibrosis. In this study the association of these biomarkers with cardiovascular risk factors and disease was explored in a large, representative population of people with type 2 diabetes mellitus. Methods Cytokeratin 18 (CK18, biomarker of hepatic inflammation) and the European Liver Fibrosis panel (ELF, biomarker of hepatic fibrosis) were measured in a random subgroup of 564 adults, aged 60–75 years at recruitment, participating in the Edinburgh Type 2 Diabetes Study (ET2DS). Data on conventional CV risk factors (body-mass index [BMI], waist circumference, blood pressure, total cholesterol, triglycerides, smoking status) and prevalent cardiovascular disease (validated myocardial infarction, angina, stroke and transient ischaemic attack events) were also available. Findings Median CK18 was 102 U/L [IQR 76–137, range 29–993] and mean ELF was 8·9 U/L [SD 0·8, range 6·9–11·6]. After adjustment for age and sex, increased CK18 was significantly associated with higher triglyceride levels (r=0·157, p=0·002). Increased ELF score was associated with higher BMI (r=0·202, p<0·001), waist circumference (r=0·139, p=0·008), and diastolic blood pressure (r=–0·045, p=0·025). Despite these associations, neither biomarker was significantly associated with prevalent cardiovascular disease (prevalent cardiovascular disease vs no cardiovascular disease, mean CK18 108·1 U/L [SD 26·2] vs 105·5 [22·6], p=0·473 and mean ELF 8·94 [0·77] vs 8·89 [0·76], p=0·442). Interpretation In people with type 2 diabetes, non-invasive biomarkers of hepatic inflammation and fibrosis are associated with a number of cardiovascular risk factors but do not appear to associate with pre-existing vascular disease. Further investigation is required to determine whether liver biomarkers predict incident cardiovascular disease in this high risk group.
