Eicosanoid synthesis in children with cholestatic disease

Abstract

The possibility of malabsorption of triglycerides contained in the diets of children with cholestasis suggests a deficiency of essential fatty acids and, therefore, probable effects on eicosanoid metabolism. Children with either biliary atresia (BA) or syndromatic paucity of interlobular bile ducts (PILBD) were evaluated as to plasma and platelet total lipid fatty acid composition and synthesis of prostaglandins (PG) E1, PGE2, PGI2, PGF2, and thromboxane (TXB2) by whole blood incubated at 37 degrees C for 10 min. In both diseases linoleate deficiency was present as shown by low 18:2 fatty acids in plasma lipids. The children with BA had lower plasma arachidonate than controls but normal eicosanoid synthesis except for excess PGI2. Those with PILBD had low platelet arachidonate and were severely deficient in TXB2 synthesis (less than 10% of controls). Three children with PILBD were fed a supplement of structured triglyceride (Captex 810) intended to provide as much as 10% of energy as linoleate for 2-3 months. Results for these three cases suggested that insufficient linoleate was absorbed to increase plasma linoleate and differences in eicosanoids could not be attributed to linoleate supplementation.

Alagille Syndrome

Alagille syndrome is a multi-system genetic disorder that can affect the liver, heart, and other parts of the body. It’s characterization includes heart problems, liver damage, jaundice, and xanthomas. Here is the latest research.
