Summary

There are currently no minimally invasive techniques for the measurement of lipopolysaccharide (LPS) and Apo-B48 that can be used in samples collected in field settings. In this project we want to explore whether postprandial assessment of biomarkers LPS and ApoB48 in blood withdrawn with a finger prick test can be used as marker for low grade inflammation and risk factor for CVD. The primary objectives of this pilot study are to a) determine whether postprandial LPS and ApoB48 levels can be assessed in finger prick blood of both lean subjects and obese subjects; and b) compare postprandial LPS and ApoB48 levels assessed in venous blood and blood collected through a finger prick test. This study is an observational pilot study in which postprandial LPS and ApoB48 will be assessed before and after ingestion of a high fat load in 5 lean and 5 obese subjects in the age range 18-70 years. Samples will be collected under fasting conditions and in response to a high fat challenge test (1, 2, 4 and 6 hours post ingestion). The risks for participation are very small if not negligible. No adverse effects of the high fat challenge were reported previously. Consumption of high amounts of saturated fat may cause some GI discomfort. Blood sampling will be performed via a cannula and the insertion can be a painful and may cause a bruise. Finger prick might also give a short pain sensation and small bruises. The amount of blood that is drawn from participants is relatively small (total 37.5 ml) and is therefore within acceptable limits. There are no direct benefits for the participants. In the BIOLOGIC study we include both lean subjects and obese subjects as we expect differences in postprandial responses related to differences in chylomicron production and LPS levels. Therefore it is important to explore these biomarkers in both target groups. This study can therefore be regarded as group-related, non-therapeutic research.
