Effect of Atorvastatin and Irbesartan, Alone and in Combination, on Postprandial Endothelial Dysfunction, Oxidative Stress, and Inflammation in Type 2 Diabetic Patients
Abstract
BACKGROUND: Postprandial hypertriglyceridemia and hyperglycemia are considered risk factors for cardiovascular disease. Evidence suggests that postprandial hypertriglyceridemia and hyperglycemia induce endothelial dysfunction and inflammation through oxidative stress. Statins and angiotensin type 1 receptor blockers have been shown to reduce oxidative stress and inflammation, improving endothelial function. METHODS AND RESULTS: Twenty type 2 diabetic patients ate 3 different test meals: a high-fat meal, 75 g glucose alone, and a high-fat meal plus glucose. Glycemia, triglyceridemia, endothelial function, nitrotyrosine, C-reactive protein, intercellular adhesion molecule-1, and interleukin-6 were assayed during the tests. Subsequently, diabetics took atorvastatin 40 mg/d, irbesartan 300 mg/d, both, or placebo for 1 week. The 3 tests were performed again between 5 and 7 days after the start of each treatment. High-fat load and glucose alone produced a decrease in endothelial function and increases in nitrotyrosine, C-reactive protein, intercellular adhesion molecule-1, and interleukin-6. These effects were more pronounced when high-fat load and glucose were combined. Short-term atorvastatin and irbesartan treatments significantly counterbalanced these phenomena, and their combination was more effective than either therapy alone. CONCLUSIONS: This study confirms an independent and cumulative effect of postprandial hypertriglyceridemia and hyperglycemia on endothelial function and inflammation, suggesting oxidative stress as a common mediator of such an effect. Short-term treatment with atorvastatin and irbesartan may counterbalance this phenomenon; the combination of the 2 compounds is most effective.

The Results report that a high-fat load and a glucose challenge each reduced endothelial function while nitrotyrosine (NT) increased; the Discussion says NT rose with hyperglycemia and hypertriglyceridemia, alone or combined. The paper does not report inflammation accompanying these changes, so that part of the claim is unsupported. (LLM, conf=0.87)

The Results (p. 363) report that short-term losartan pretreatment was associated with less microvascular endothelial dysfunction (22% versus 75%). Macrovascular function was comparable between groups, however, so the claim overgeneralizes the protective effect of acute AT-1 receptor blockade. (LLM, conf=0.87)

The Abstract (page not provided) reports that simvastatin plus ramipril improved flow-mediated dilation and reduced markers of oxidative stress and inflammation in hypercholesterolemic patients. The Discussion (page not provided) says the combination had greater effects than simvastatin alone on these measures. This supports the citing sentence’s hedged claim about emerging evidence for combining a statin with angiotensin II system inhibition; this trial tested an ACE inhibitor, not AT-1 receptor blockade.

The Abstract reports that losartan plus simvastatin improved renal function more than either drug alone in diabetic rats. It does not report greater improvement in endothelial dysfunction or oxidative stress; the Discussion says the combination did not further reduce TGF-β1 expression, and the Abstract reports no added benefit for VEGF expression.

The high-fat meal and the 75 g glucose challenge reproduce the postprandial metabolic state relevant to diabetic patients' daily lives.
“Diabetic patients ate, in randomized order, 3 different menus on 3 different days: test 1, a high-fat meal; test 2, 75 g glucose alone; and test 3, a high-fat meal plus 75 g glucose.”

The subjects kept to their usual diets throughout the study.
“All subjects were recommended to consume their habitual diets during the entire study period.”

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.
A language model drew the claims from the paper on 2026-09-27, under version 3 of the claim definition (prompt extract-v3).
A second model labelled each claim on 2026-09-27 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Cited sources are checked with a language model’s help (gpt-6-sol).
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.
