Abstract

Monocyte-derived microparticles play an important role in the pathogenesis of diabetic vasculopathy, and angiotensin II receptor blocker and statin have been shown to have a beneficial effect on the angiopathies of hypertension and hyperglycemia in patients with type 2 diabetes mellitus. However, the interaction between angiotensin II receptor blocker and statin, and monocyte-derived microparticles in atherosclerosis is poorly understood. The effects of losartan and simvastatin on circulating concentrations of monocyte-derived microparticles, chemokines, and soluble adhesion markers were studied in hypertensive patients with or without type 2 diabetes mellitus. Monocyte-derived microparticles were measured by flow cytometry, and levels of serum chemokines (MCP-1 and RANTES) and soluble adhesion markers (sP-selectin and sVCAM-1) were measured by enzyme-linked immunosorbent assay. Losartan decreased both the systolic and diastolic blood pressure in hypertensive patients with and without type 2 diabetes mellitus. The concentrations of monocyte-derived microparticles, chemokines, and soluble adhesion molecules were higher in hypertensive patients who also had type 2 diabetes mellitus vs. those who did not. The administration of angiotensin II receptor blocker decreased the circulating concentration of all these markers. In addition, all markers were decreased by combination therapy, and monocyte-derived microparticles were decreased more with combination therapy with losartan and simvastatin than monotherapy with losartan. The administration of angiotensin II receptor blocker inhibited monocyte-derived microparticle generation and suggests that angiotensin II is intimately related to vascular changes that occur in type 2 diabetes mellitus. Combination therapy with a statin and angiotensin II receptor blocker might be valuable as anti-atherosclerotic therapy in patients with type 2 diabetes mellitus and nephropathy.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
