Insights
Ursodeoxycholic acid (UDCA) improved peripheral blood flow in patients with chronic heart failure (CHF). This study found UDCA well tolerated and beneficial for liver function markers in CHF patients.
Area of Science:
- Cardiology
- Hepatology
- Pharmacology
Background:
- Endothelial dysfunction is a key issue in chronic heart failure (CHF), limiting exercise capacity.
- Bacterial lipopolysaccharide can exacerbate endothelial dysfunction via proinflammatory cytokine release.
- Ursodeoxycholic acid (UDCA), used for liver disease, possesses anti-inflammatory properties and may mitigate lipopolysaccharide effects.
Purpose of the Study:
- To evaluate the impact of ursodeoxycholic acid (UDCA) on endothelial function in chronic heart failure (CHF) patients.
- To assess changes in inflammatory markers and peripheral blood flow following UDCA treatment in CHF.
Main Methods:
- A prospective, randomized, double-blind, placebo-controlled crossover study was conducted.
- 17 male patients with CHF (NYHA class II/III, LVEF <45%) received UDCA (500 mg BID) or placebo for 4 weeks each.
- Primary endpoint: post-ischemic peak peripheral arm blood flow measured by strain-gauge plethysmography.
Main Results:
- UDCA significantly improved peak post-ischemic arm blood flow by 18% (p=0.038) compared to placebo.
- A trend towards improved leg blood flow was observed (+17%, p=0.079).
- UDCA lowered liver enzymes (GGT, AST) and soluble TNFα receptor 1 (all p<0.05), indicating improved liver function.
Conclusions:
- Ursodeoxycholic acid (UDCA) is safe and well-tolerated in chronic heart failure (CHF) patients.
- UDCA demonstrates efficacy in improving peripheral blood flow in CHF.
- The treatment is associated with beneficial effects on liver function markers in this population.
Objectives:
This study sought to assess the effects of ursodeoxycholic acid (UDCA) on endothelial function and inflammatory markers in patients with chronic heart failure (CHF).
Background:
Endothelial dysfunction is commonly observed in patients with CHF, and it contributes to the limitation in exercise capacity that accompanies this condition. Bacterial lipopolysaccharide may trigger proinflammatory cytokine release and promote further endothelial dysfunction. UDCA, a bile acid used in the treatment of cholestatic liver disease, has anti-inflammatory and cytoprotective properties and may contribute to the formation of mixed micelles around lipopolysaccharide. These properties may help to improve peripheral blood flow in patients with CHF.
Methods:
We performed a prospective, single-center, double-blind, randomized, placebo-controlled crossover study of UDCA in 17 clinically stable male patients with CHF (New York Heart Association functional class II/III, left ventricular ejection fraction <45%). Patients received in random order 500 mg UDCA twice daily for 4 weeks and placebo for another 4 weeks. The primary endpoint was post-ischemic peak peripheral arm blood flow as assessed by strain-gauge plethysmography.
Results:
Sixteen patients completed the study. UDCA was well tolerated in all patients. Compared with placebo, UDCA improved peak post-ischemic blood flow in the arm (+18%, p = 0.038), and a trend for improved peak post-ischemic blood flow in the leg was found (+17%, p = 0.079). Liver function improved: compared with placebo, levels of γ-glutamyl transferase, aspartate transaminase, and soluble tumor necrosis factor α receptor 1 were lower after treatment with UDCA than after placebo (all p < 0.05). There was no change in 6-min walk test or New York Heart Association functional class, and levels of tumor necrosis factor α and interleukin-6 were unchanged or increased compared with placebo.
Conclusions:
UDCA is well tolerated in patients with CHF. UDCA improves peripheral blood flow and is associated with improved markers of liver function.
