Abstract:
The role of polymorph nuclear neutrophils (PMN) in limb ischemia and reperfusion has been recognized only in recent years. The present study aimed to investigate the systemic and local (in femoral venous blood) effects of intra-arterially or intravenously applied prostaglandin E 1 (PGE 1 ) on systemic and ischemia-induced local changes in neutrophil function. Thirty patients with intermittent claudication were randomly assigned to intra-arterial or intravenous infusion of prostaglandin E 1 (10 mgIAor15 mg IV over 30 min). Prior to infusion femoral arterial and venous blood samples were obtained from the predominantly affected leg under resting conditions and immediately after a 3-min period of ischemia induced by suprasystolic thigh compression. After 24 h additional blood samples were obtained at baseline, following infusion of prostaglandin E 1 , and again after another 3-min period of ischemia following the prostaglandin E 1 infusion. Intra-arterially administered prostaglandin E 1 caused an increase in the PMN count by 3.5 ± 2% (p,0.05) and a decrease in free oxygen radical production by 13 ± 8% (p,0.05) measured by whole blood chemiluminescence. Additionally, a trend for lower PMN filterabilities (9 ± 12%, NS) was observed. Intra-arterially infused prostaglandin E 1 significantly reduced the ischemia-induced decrease in neutrophil filterability (arterial and venous blood difference after ischemia - control: 22 ± 17% (p,0.05); IA PGE 1 :8 ± 11% (NS), each compared to baseline). Intravenously administered prostaglandin E 1 showed similar systemic effects as the intra-arterial application, but did not affect the ischemia-induced changes in neutrophil filterability. In conclusion, prostaglandin E 1 reduces PMN activation in patients with peripheral arterial occlusive disease.
