β-Escin and Chokeberry Fruit Extract Supplementation in Smokers as Potential anti-Inflammatory Protection-a Pilot...

Area of Science:

• Pharmacology
• Toxicology
• Biochemistry

Background:

• Cigarette smoking is a major global public health issue, causing significant inflammation and toxicity.
• Tobacco smoke exposure leads to increased oxidative stress and inflammatory responses in the airways.
• Current interventions for smoking-related inflammation have limitations.

Purpose of the Study:

• To evaluate the anti-inflammatory potential of beta-escin combined with chokeberry fruit extract in tobacco smokers.
• To investigate the underlying mechanisms of action, including effects on inflammatory markers and antioxidant capacity.
• To assess the impact on aldehyde dehydrogenase (ALDH) activity.

Main Methods:

• A pilot study involving nine smoking volunteers receiving daily beta-escin and chokeberry extract for 7 days.
• Analysis of neutrophil and macrophage counts, IL-6 and IL-8 concentrations in induced sputum.
• Measurement of antioxidant capacity in sputum and saliva, and ALDH activity in peripheral blood mononuclear cells (PBMCs) in vitro and in vivo.

Main Results:

• A significant decrease in neutrophil and increase in macrophage concentration in smokers' sputum.
• A notable rise in the antioxidant capacity of induced sputum and saliva.
• Strong upregulation of ALDH activity in PBMCs observed both in vitro and in vivo.

Conclusions:

• Beta-escin and chokeberry fruit extract show promise as an anti-inflammatory intervention for smokers.
• The observed increase in ALDH activity and antioxidant capacity may contribute to reduced airway inflammation and toxicity.
• This study provides a proof-of-concept for a novel approach to mitigate smoking-related health risks.
