Vitamin D alleviates indoxyl sulfate-induced inflammatory and cholesterol dysregulation in macrophages: Implications for vascular health in patients receiving hemodialysis.

Article D Peer reviewed Preclinical

Key takeaways

Indoxyl sulfate is a waste product that builds up when kidneys fail and that damages blood vessels, which matters for people on dialysis. Researchers put this toxin on immune cells called macrophages in the lab, then added vitamin D. Vitamin D calmed the inflammation and the cholesterol handling problems the toxin set off. This was cells in a dish, not people, so it does not show that vitamin D protects blood vessels in dialysis patients.
