Oral and gum health and saliva markers in people with hepatitis B and D

Official title: Oral-Periodontal Evaluation and Assessment of Biomarkers in Oral Fluids in Patients With Hepatitis B+D Treated With Bulevirtide

Run by Research Center of Periodontal-Systemic Interactions · NCT07491848 · Data updated 2026-11-12

This project will test whether gum inflammation and specific saliva and gum-fluid markers differ in adults with hepatitis B and D—both those taking bulevirtide and those not—compared with healthy adults.

Is this trial a fit for you?

Likely a good fit

Ideal participants are adults (age 18+) with confirmed hepatitis B and D co-infection—either receiving bulevirtide or not—or systemically healthy adults willing to undergo oral exams and saliva and gingival crevicular fluid collection.

Probably not a fit

People with other systemic diseases that affect periodontal health (for example uncontrolled diabetes or autoimmune conditions), recent oral or periodontal surgery within six months, pregnancy or lactation, or those unable to provide informed consent are unlikely to benefit or may be ineligible.

What this trial studies

This prospective case-control study will compare oral-periodontal clinical measures and targeted inflammatory biomarkers in saliva and gingival crevicular fluid across three groups: adults with hepatitis B+D on bulevirtide, adults with hepatitis B+D not on bulevirtide, and healthy controls. A specialist periodontist will perform standardized oral exams with photographs, and non-invasive saliva and crevicular fluid samples will be collected at baseline and at six months. Samples will be analyzed at the Immunology Laboratory of the University of Medicine and Pharmacy of Craiova and at the University of Amsterdam to quantify inflammatory mediators. Statistical analysis will examine associations between periodontal inflammation, oral biomarkers, and hepatitis B+D status and treatment.

Why it matters

Potential benefit: If successful, the work could identify oral biomarkers linked to hepatitis B+D and effects of bulevirtide, helping guide monitoring and targeted oral care for affected patients.

How similar studies have gone: Prior studies have linked oral inflammation and saliva biomarkers to systemic liver disease, but using these markers specifically in hepatitis B+D patients and in relation to bulevirtide treatment is relatively novel.
