A summary of the research article "Resveratrol supplementation improves endothelial function in chronic kidney disease" published by the American Physiological Society has important details as follows:

Origin and importance

Patients with chronic kidney disease (CKD), especially those who also have diabetes. There is a very high risk of developing cardiovascular disease (CVD), which is partly caused by: "Endothelial Dysfunction" of vascular epithelial cells, the researchers therefore wanted to study whether resveratrol, a natural polyphenol found in grapes and berry plants, Will it be able to help improve blood vessel function in this group of patients?

Method of study

* Sample group: 25-28 adults with stage 3 chronic kidney disease (Stage 3 CKD) and type 2 diabetes (Type 2 Diabetes).

* Experimental design: Randomized, double-blind, placebo-controlled trial. (Placebo-controlled) and crossover study

* Method: Patients were given 400 mg of resveratrol extract/day (divided into 200 mg in the morning and 200 mg in the evening) for 6 weeks.

* There is a 2 week washout period before switching to placebo for another 6 weeks (or alternating).

* Measurement: Measures the function of the vascular epithelium by measuring the expansion of the arteries in the arm when subjected to blood shear stress (Brachial Artery Flow-Mediated Dilation or BA-FMD).

Important study results

1. Significant improvement in blood vessel function: BA-FMD (vasodilatation) values increased significantly after receiving resveratrol. Compared to the placebo group

2. Other factors were unchanged: kidney function (eGFR), cumulative blood glucose (HbA1c) and blood pressure. no change After taking resveratrol

3. Smooth muscle response: vasodilatation from glyceryl trinitrate. (Nitroglycerin-mediated dilation) was unchanged. This shows that the beneficial effects are specific to the epithelial cells. (Endothelial) is not a normal vascular muscle.

Conclusion

Supplementing with resveratrol (Resveratrol) effectively increases and develops the function of blood vessel epithelial cells in patients with chronic kidney disease who also have diabetes. This result occurs directly in the blood vessels. It does not rely on changes in sugar levels, blood pressure, or kidney function.
