title: Fat clearances and hyperlipidaemia in renal allograft recipients--the role of insulin resistance.
abstract: The mechanism of hyperlipidaemia in renal allograft recipients was investigated in 19 patients randomly selected from a cohort of 54 patients with functioning renal allografts. Serum cholesterol, triglyceride and high-density lipoprotein cholesterol concentrations as well as plasma immunoreactive insulin levels were measured in fasting blood samples. Intravenous fat tolerance tests were performed before and 15 min after heparin administration. Renal allograft recipients had reduced fractional clearance rates of Intralipid and a positive correlation was demonstrated between plasma immunoreactive insulin levels and serum triglyceride concentrations. Plasma immunoreactive insulins also correlated inversely with fractional clearance rates of Intralipid. It was concluded that both increased production and decreased removal of lipoproteins contribute to the hyperlipidaemia and that insulin resistance due to corticosteroids was the centre of the problem.
