What the study found

The study found that probiotic supplementation may improve postoperative antioxidant status in patients undergoing open-heart surgery. The authors also report that probiotic supplementation did not significantly change malondialdehyde, a marker of oxidative stress.

Why the authors say this matters

The authors conclude that probiotics may serve as an adjunctive therapy, meaning an added treatment, to enhance antioxidant defenses and mitigate postoperative oxidative stress. The study suggests this could be relevant for patients undergoing open-heart surgery.

What the researchers tested

This randomized controlled trial enrolled 37 patients with cardiovascular disease scheduled for open-heart surgery. Eighteen patients received probiotic supplementation and 19 received placebo, starting 1 day before surgery and continuing for 2 weeks. The researchers measured plasma malondialdehyde (MDA) and total antioxidant capacity (TAC) at baseline and at the end of the intervention.

What worked and what didn't

Total antioxidant capacity increased in the probiotic group, and the report indicates this change was statistically significant. No significant change was found for malondialdehyde. The abstract does not provide the exact numeric results in the text available here.

What to keep in mind

The study was small, with 37 patients initially recruited. The abstract does not describe longer-term follow-up beyond the 2-week intervention, and it does not provide detailed limitations in the available summary. The authors state that further large-scale studies are warranted.

Key points

  • Probiotic supplementation may improve postoperative antioxidant status after open-heart surgery.
  • The study found no significant change in malondialdehyde, an oxidative stress marker.
  • Thirty-seven patients were recruited and split between probiotic and placebo groups.
  • Treatment began 1 day before surgery and continued for 2 weeks.
  • The authors call for further large-scale studies.
