Anti-inflammatory response to 1,8-Cineol and associated microbial communities in Otitis media patients

Area of Science:

• Otolaryngology
• Microbiology
• Pharmacology

Background:

• Chronic Otitis Media (COM) involves persistent inflammation and bacterial colonization, often complicated by antibiotic resistance.
• Current surgical and antibiotic treatments for COM face challenges due to developing antibiotic resistance.
• Off-label use of natural compounds is being explored to address treatment limitations.

Purpose of the Study:

• To investigate the efficacy of the natural drug 1,8-Cineol as an off-label treatment for Chronic Otitis Media (COM).
• To assess the impact of 1,8-Cineol on pathogenic microbial loads in COM patients.
• To correlate the clinical outcomes with microbiological findings following 1,8-Cineol therapy.

Main Methods:

• Patients with COM received standard antibiotic therapy and middle ear surgery.
• Microbiological samples were collected from the auditory canal and stool.
• Patients were treated off-label with 1,8-Cineol, and clinical courses were monitored.
• Microbial investigations were correlated with clinical observations.

Main Results:

• 1,8-Cineol therapy led to a significant reduction in inflammatory microbes, including P. aeruginosa and Proteus mirabilis, in ear samples.
• A decrease in intestinal Prevotella copri was observed.
• Certain individuals experienced improved clinical outcomes associated with microbial reductions.
• The study identified manifold anti-inflammatory effects of 1,8-Cineol.

Conclusions:

• The natural monoterpene 1,8-Cineol demonstrates promising anti-inflammatory properties in Chronic Otitis Media patients.
• 1,8-Cineol may help reduce specific pathogenic bacteria associated with COM and gut microbiota.
• Further research into the mechanisms of 1,8-Cineol could enhance its therapeutic application for otitis media.
