Abstract

The absence of a reduction in peripheral vascular resistance secondary to hypervolaemia leads to so-called volume hypertension. In order to study whether a deficient formation of the vasodilator autacoid prostaglandin E2 (PGE2) contributes to the preservation of inadequate vascular tone during extracellular volume expansion, arterial plasma PGE2 and the stable PGE2 metabolite 13, 14-dihydro-15-keto-PGE2 (PGE2-M) were determined in 13 oligoanuric women on chronic haemodialysis. Prior to treatment eight of them had hypervolaemia and hypertension (mean arterial pressure (MAP) 128±3mmHg (x;±SE)) and five patients had hypervolaemia of a similar degree but were not hypertensive (MAP: 99±4 mmHg P<0.005). Before haemodialysis the arterial PGE2 and PGE2-M concentrations were less (P<0.05) in hypertensive (11 observations in eight patients) than in normotensive patients (ten observations in five patients). As blood pressure decreased during the course of haemodialysis of volume hypertensive patients, the concentration of PGE2 and PGE2-M increased (P<0.02) by 104±43% and 89±32%, respectively. In normotensive patients neither blood pressure nor the concentration of PGE2 and PGE2-M were found to change during treatment. Since volume hypertension was associated with reduced values and dialysis induced normalisation of blood pressure with increased arterial values of PGE2 and PGE2-M, we hypothesise that the development of hypertension associated with fluid overload of haemodialysed patients may be related to a decreased release of prostaglandin E2.
