For patients with anti-HBc IgG positivity requiring Hepatitis B virus (HBV) prophylaxis, the long-term physiological impact of oral antivirals remains a concern. This study aims to prospectively monitor bone, renal, and metabolic dysfunctions associated with oral antiviral use and other systemic risk factors over a long-term period.\n\nMethods: The REANT Cohort is designed as a 4-year, multicenter prospective study. The cohort will consist of patients initiated on HBV prophylaxis due to immunosuppressive treatment. Participants will undergo regular longitudinal assessments to evaluate bone mineral density, renal filtration and tubular functions, and metabolic profiles. The interplay between antiviral therapy, baseline comorbidities, and long-term organ dysfunction will be analyzed.\n\nConclusion: The findings from the REANT Cohort are expected to provide robust evidence regarding the safety of long-term HBV prophylaxis and assist in the development of monitoring guidelines for immunosuppressed patients with latent HBV infection.",[26],"HBV",[28,29],"HBV reactivation","Immunosuppressive therapy","RECRUITING","2026-04-09",{"date":33,"type":34},"2026-04-14","ACTUAL",{"date":36,"type":34},"2026-03-09",{"date":38,"type":21},"2029-12-31",{"name":40,"class":41},"Yaşar Bayındır, MD","OTHER",1,{"id":44,"slug":45,"hasResults":11,"nctId":46,"briefTitle":47,"officialTitle":48,"acronym":4,"eligibilityCriteria":49,"healthyVolunteers":11,"sex":16,"minAge":17,"maxAge":18,"enrollmentInfo":50,"targetDuration":4,"studyType":23,"phases":4,"briefSummary":52,"conditions":53,"keywords":55,"overallStatus":60,"whyStopped":4,"lastUpdateSubmitDate":61,"lastUpdatePostDateStruct":62,"startDateStruct":63,"completionDateStruct":65,"leadSponsor":67,"locationsCount":42},"100628268","entecavir-resistance-associated-mutations-in-chronic-hbv-patients-in-turkey-stream-study-100628268","NCT07459426","Entecavir Resistance-Associated Mutations in Chronic HBV Patients in Turkey (STREAM Study)","Sequencing-Based Tracking of Entecavir Resistance-Associated Mutations in Chronic Hepatitis B Patients: A Multicenter Observational Study (STREAM)","Inclusion Criteria:\n\n* Age ≥18 years\n* HBsAg positive\n* Group 1: Either treatment-naïve participants with HBV DNA\\>2000 IU\u002Fml\n* Group 2: Prior lamivudine therapy ≥6 months with switch to ADVor TDF or TAF\n* Ability to provide informed consent\n\nExclusion Criteria:\n\n* Prior entecavir exposure\n* Prior telbivudine exposure\n* Age \\\u003C18 years\n* Inability to provide informed consent Note: Previous adefovir or (pegylated) interferon use is not an exclusion criterion.\n\nPatients with insufficient sample volume or inadequate DNA quality for sequencing will be excluded from final analysis.",{"count":51,"type":21},700,"Chronic hepatitis B is a long-term viral infection that affects millions of people worldwide. Patients usually require lifelong antiviral treatment to control the virus and prevent liver damage.\n\nSome older antiviral medications, such as lamivudine, can lead to the development of viral resistance. This means the virus changes in a way that makes certain treatments less effective. Even though newer drugs like entecavir are stronger and more resistant to these changes, previous exposure to lamivudine may increase the risk of developing additional resistance mutations.\n\nBy analyzing viral genetic material from blood samples using advanced sequencing technology, this research will help improve understanding of antiviral resistance patterns in patients with chronic hepatitis B in Turkey and may support better treatment decisions in the future.",[54],"Hepatitis B, Chronic",[56,57,58,59],"Chronic hepatitis B","Lamivudine","Entecavir","Antiviral resistance","NOT_YET_RECRUITING","2026-03-05",{"date":36,"type":34},{"date":64,"type":21},"2026-03-15",{"date":66,"type":21},"2027-03-15",{"name":40,"class":41},{"id":69,"slug":70,"hasResults":11,"nctId":71,"briefTitle":72,"officialTitle":73,"acronym":74,"eligibilityCriteria":75,"healthyVolunteers":76,"sex":16,"minAge":17,"maxAge":4,"enrollmentInfo":77,"targetDuration":79,"studyType":23,"phases":4,"briefSummary":80,"conditions":81,"keywords":87,"overallStatus":30,"whyStopped":4,"lastUpdateSubmitDate":90,"lastUpdatePostDateStruct":91,"startDateStruct":93,"completionDateStruct":95,"leadSponsor":97,"locationsCount":98},"100535188","find-hdv-and-determine-its-status-in-turkey-100535188","NCT06248580","Find HDV and Determine Its Status in Turkey","Find HDV and Determine Its Status in Turkey \"SITU(HD)VATION\"","SITUHDVATION","Inclusion Criteria:\n\n* Adults (Age≥18)\n* Being HBsAg positive for at least six months\n* Being a citizen of the Republic of Türkiye\n\nExclusion Criteria:\n\n* There are no exclusion criteria in this study.",true,{"count":78,"type":21},20000,"13 Months","The aim of these study to determine the prevalence of hepatitis Delta virus (HDV) infections and the prognosis of HDV patients in Turkey's southeast.
