Clinical Trial Results. org The PIOSTAT Study: Background Markers of inflammation include high sensitivity C-reactive protein (hsCRP), matrix metalloproteinase (MMP)-9, and plasminogen activator inhibitor (PAI)-1. Markers of inflammation include high sensitivity C-reactive protein (hsCRP), matrix metalloproteinase (MMP)-9, and plasminogen activator inhibitor (PAI)-1. Elevations of these markers have been associated with higher rates of future CV events. Elevations of these markers have been associated with higher rates of future CV events. Hanefeld et al.

Clinical Trial Results. org The PIOSTAT Study: Background (cont.) Statins are associated with a reduction in these inflammatory markers. Statins are associated with a reduction in these inflammatory markers. A new class of drugs, the thiazolidinediones (TZDs) (PPAR-γ agonists), have also been shown to have anti-inflammatory properties, reducing CRP, MMP-9, (MCP)-1, and soluble CD40L. A new class of drugs, the thiazolidinediones (TZDs) (PPAR-γ agonists), have also been shown to have anti-inflammatory properties, reducing CRP, MMP-9, (MCP)-1, and soluble CD40L. The TZD Pioglitazone has recently been associated with a reduction in cardiovascular endpoints in patients with type 2 diabetes mellitus.

Clinical Trial Results. org The PIOSTAT Study: Background (cont.) However, there is only scarce information on the benefits of treatment with TZDs, alone or in combination with statins, in patients with CVD and increased hs-CRP levels. However, there is only scarce information on the benefits of treatment with TZDs, alone or in combination with statins, in patients with CVD and increased hs-CRP levels. This study aimed to investigate the safety and efficacy of pioglitazone and simvastatin in combination versus each drug individually in non- diabetic subjects with CVD and elevated hs-CRP levels.

Pioglitazone and simvastatin exerted anti- inflammatory effects in non-diabetic patients with CVD and elevated hs-CRP. Combining the two drugs resulted in an additive effect on low-grade inflammation, without a significant increase in serious adverse events.
