Effect of a Probiotic Preparation (VSL#3) on CardiovascularRisk Parameters in Critically-Ill Patients

Area of Science:

• Critical care medicine
• Microbiology
• Nutritional science

Background:

• Cardiovascular disease (CVD) is a leading cause of global mortality, often linked to lipid abnormalities.
• Critically ill patients are susceptible to lipid disorders and inflammation.
• Probiotics show potential in restoring lipid homeostasis and managing inflammation.

Purpose of the Study:

• To evaluate the impact of probiotic supplementation on inflammation, antioxidant capacity, and lipid peroxidation in critically ill patients.
• To assess changes in serum lipid profiles and high-sensitivity C-reactive protein (hs-CRP) levels.

Main Methods:

• A randomized controlled trial involving 40 critically ill patients.
• Participants received either probiotics or a placebo for 7 days.
• Serum levels of triglyceride (TG), total cholesterol, HDL-C, LDL-C, and hs-CRP were measured pre- and post-intervention.

Main Results:

• Probiotic administration led to significant reductions in TG (P=0.043) and hs-CRP (P=0.003) levels.
• A significant increase in HDL-C levels was observed (P<0.001) in the probiotic group.
• No significant differences were found in total cholesterol or LDL-C levels between the groups.

Conclusions:

• Probiotics effectively reduce triglyceride and hs-CRP levels in critically ill patients.
• Probiotic supplementation can improve HDL-C levels in this patient population.
• Probiotics do not significantly alter total cholesterol or LDL-C levels in critically ill patients.
