An observational study in HBV (Hepatitis B Virus) and HCV Infection, sponsored by IRCCS Ospedale San Raffaele. Not yet recruiting. Open to participants aged 18 Years to 50 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2025-11-21.
Sponsored by IRCCS Ospedale San Raffaele · Observational
The goal of this observational study is to assess the effectiveness of targeted screening for Hepatitis B (HBV) and Hepatitis C (HCV) infections in adults aged 18 to 50 from the Chinese community residing in Milan.
The main questions it aims to answer are:
Participants will:
The study will be conducted in public spaces within Milan's Chinatown, during monthly sessions, until 1,000 participants are enrolled. Each session will last approximately 30-60 minutes per participant.
1,045 studies on the registry are indexed under Hepatitis B; 139 are open to participants now.
This study's planned enrollment of 1,000 is above the median of 365 across 251 observational studies indexed under Hepatitis B.

Counted across the registry records on this site, refreshed daily.
Adults aged 18 to 50 years who self-identify as part of the Chinese community residing in Milan. Participants must be able to provide informed consent, complete a short questionnaire and undergo rapid testing for HBV and/or HCV. Both males and females are eligible. The study aims to reach individuals who may face cultural, linguistic or systemic barriers to healthcare access.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.
Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.
Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.
After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.
