1. The metabolic effects of intraperitoneal and subcutaneous insulin delivery were compared in a crossover manner in six C-peptide-negative diabetic patients with end-stage renal disease on continuous ambulatory peritoneal dialysis. Each treatment period lasted at least 3 months. Hyperinsulinaemic euglycaemic clamp was performed and glucose turnover assessed using [3-3H]glucose as a tracer. 2. During intraperitoneal delivery the daily insulin dose was 2.4 times higher than during subcutaneous administration and glycaemic control was significantly better (HbA1c 7.63% ± 0.46% and 9.52% ± 0.51% during intraperitoneal and subcutaneous insulin respectively, P < 0.01). The number of hypoglycaemic episodes was lower during intraperitoneal insulin than during subcutaneous therapy. 3. Intraperitoneal insulin resulted in an enhanced glucose disposal rate (P < 0.01) and reduced fasting hepatic glucose production (P < 0.01). High-density lipoprotein-cholesterol decreased and the ratio of low-density lipoprotein/high-density lipoprotein-cholesterol increased significantly (P < 0.05) during intraperitoneal insulin delivery. 4. The results suggest that intraperitoneal insulin, while resulting in better glycaemic control and improved insulin sensitivity than subcutaneous insulin, increases serum triacylglycerol and total cholesterol and reduces high-density lipoprotein-cholesterol, possibly via a direct effect on the liver.

Haematological and serum biochemical measurements in male spontaneously epileptic rats (SER; double mutants homozygous for zitter and tremor genes) were compared with the values for related rat strains. Some haematological values were low in TRM rats and total leukocyte counts were high in ZI and TRM rats. TRM rats showed higher total cholesterol, phospholipid, high-density lipoprotein cholesterol and calcium values, and lower albumin value than Kyo: Wistar rats. Zitter homozygous rats including SER exhibited low total cholesterol, phospholipid and high-density lipoprotein cholesterol values. The SER showed an increase in urea nitrogen, aspartate aminotransferase and alanine aminotransferase values, and a decrease in glucose value, suggesting deterioration of the whole body with age.

Background. Lower serum high-density lipoprotein cholesterol and increased ratio of omega-6/omega-3 fatty acids have been reported in unipolar and bipolar depressed patients. Changes in cholesterol and fatty acids have been suggested to affect membrane viscosity and consequently serotonergic neurotransmitter expression.The goal of this study was to investigate whether lower baseline cholesterol and increased omega-6 and lower omega-3 fatty acids are present in healthy first-degree relatives of bipolar patients compared with controls and whether these changes were associated with neuroendocrine responses to an i.v. tryptophan challenge or mood.Method. Baseline cholesterol, fatty acids and mood were determined in healthy first-degree relatives of patients with bipolar disorders (N=30) and healthy matched controls (N=15) (parallel-group design). Prolactin and cortisol were measured following tryptophan infusion.Results. First-degree relatives showed significantly lower plasma high-density lipoprotein cholesterol and increased total omega-6 fatty acids in phospholipids. Lower total omega-3 and higher total omega-6 fatty acids in phospholipids were positively correlated with peak prolactin response to tryptophan. Lower total omega-3 fatty acids in phospholipids and cholesteryl esters were associated with lower mood.Conclusions. Abnormalities of lower plasma high-density lipoprotein cholesterol and increased total omega-6 fatty acids in phospholipids in these subjects are in agreement with findings in bipolar and major depressed patients. Changes in fatty acids show an association with central serotonergic parameters. It is suggested that these abnormalities in cholesterol and fatty acids may constitute a trait marker for bipolar disorders.
