Isoprostane 8-epi-PGF2alpha is frequently increased in patients with muscle pain and/or CK-elevation after HMG-Co-enzyme-A-reductase inhibitor therapy.
Muscle pains with or without CK-elevation are among the most frequently observed side-effects in patients with hyperlipoproteinemia on various statins. The pathophysiological background, however, remains obscure.. We examined isoprostane 8-epi-PGF2alpha, a marker of in-vivo oxidation injury, in plasma, serum and urine in these patients at baseline, when muscle problems manifested and different time intervals after withdrawing the respective statin. A healthy control group and a group of untreated patients with hyperlipoproteinemia were run as controls.. The majority of patients with muscular side-effects show elevated 8-epi-PGF2alpha in plasma and urine, whereas serum values were elevated only to a lesser extent. Stopping statin therapy or successfully changing to another member of this family of compounds resulted in a normalization of the values in all patients.. These findings indicate a significant involvement of oxidative injury in the muscular side-effects of statins in patients suffering from hyperlipoproteinemia.

Eicosanoid generation and responsiveness of human lymphatics in hyperlipoproteinemia.
In this work, the oxidation injury in hyperlipoproteinemia (HLP) was determined by measuring the isoprostane 8-epi-prostaglandin (PG) F2alpha in human lymphatics, lymph fluid, plasma, serum and urine. Lymphatics from 6 patients with HLP generated less PGI2 and contained more 8-epi-PGF2alpha as compared to 6 normolipemics without risk factors. Likewise, plasma (29.3 vs 19.7 pg/ml), lymph fluid (137.3 vs 65.3 pg/ml), serum (286.7 vs 204.1 pg/ml) and urinary (360.8 vs 241.0 pg/mg creatinine) values of 8-epi-PGF2alpha in HLP (as compared to normolipemics) were significantly elevated. Lymphatics from HLP showed an enhanced contractile response, less 14C-arachidonic acid conversion to PGI2 and less PGI2-formation upon various stimuli compared to normolipemics of comparable age. These findings indicate that HLP-induced oxidation injury, resulting in an altered (iso-)eicosanoid production and function, may also significantly affect (patho-) physiology of lymphathics.
