Synthesis of thromboxane B2 in uraemia and the effects of dialysis. 1983

M Winter, and G Frampton, and A Bennett, and S J Machin, and J S Cameron

The generation of thromboxane B2 (TxB2) from its natural precursor, arachidonic acid, was studied in vitro in order to assess further the prostaglandin pathway in the platelets of patients with chronic renal failure. Some, but not all patients with conservatively treated uraemia synthesised significantly less TxB2 then controls and the same patients were also hypo-aggregable to arachidonic acid. The synthesis of TxB2 appeared normal in a group of patients on chronic ambulatory peritoneal dialysis (CAPD). In contrast, a group of patients on long-term maintenance haemodialysis produced significantly greater amounts of TxB2 and were hyper-aggregable to arachidonic acid, a finding which may be relevant to the high incidence of atherosclerosis and vascular disease in these patients.
