NCT06564051
This study evaluates the incidence of monoclonal B-cell lymphocytosis MBL) in patients with chronic hepatitis C and to determine if monoclonal b-cell lymphocytosis is affected by treatment for hepatitis C.
NCT03743272
This study aims to prospectively assess the repeatability and reproducibility of iron-corrected T1 (cT1), T2\*, and hepatic proton density fat fraction (PDFF) quantification with multiparametric MRI using the LiverMultiScan™ (LMS, Perspectum Diagnostics, Oxford, UK) protocol across different field strengths, scanner manufacturers and models.
NCT04222803
The study aims to investigate possible associations between ongoing viral hepatitis (i.e. hepatitis A, B, C or E virus infection) and ultrasound or computed tomography-verified gallstone disease.
NCT06360484
Background: Sudan has a high prevalence of hepatitis B surface antigen (HBsAg), exceeding 8%. The prevalence of hepatitis B varies across different regions of Sudan, ranging from 6.8% in central Sudan to as high as 26% in southern Sudan. Hepatitis B virus (HBV) infection can lead to various complications, including cirrhosis, liver failure, and hepatocellular carcinoma (HCC). Hepatitis D virus (HDV) relies on HBV for replication and can accelerate the progression of HBV-related liver diseases, leading to more severe outcomes. This study aims to determine the prevalence of HDV infection among Sudanese patients with HBV-related liver diseases and to investigate the clinical characteristics of patients with HBV/HDV co-infection. Design/Method: This descriptive cross-sectional hospital-based study was conducted at Ibn Sina Specialized Hospital in Sudan between June and September 2022. Ninety HBV patients aged 16 years and above were included. Patients were interviewed using a structured questionnaire, and medical histories and examinations were recorded. Investigations included liver function tests, abdominal ultrasounds, and ELISA for Ant-HDV-IgG
NCT01953458
* The cohort will integrate clinical, genetic, pharmacogenomics, environmental, biomarkers and behavioral data in a large number of patients and will be a leading equipment for crossdisciplinary and translational research on hepatitis. * The cohort will be the main support for estimating the relative effects of treatments and for further cost-effectiveness studies on the management and treatment options in chronic HCV (Hepatitis C Virus)and HBV (Hepatitis B virus)infections.
NCT04304612
The consortium will develop a new in vitro diagnostic (IVD) test to screen donated blood for bloodborne infectious pathogens, saving blood banks time and costs required for analysis of mandatory pathogens. The IVD test is a multiplex immunoassay that simultaneously screens for six bloodborne infectious diseases per blood sample. In this project, a mix of diagnostic protein markers will be developed and validated to lowdown an IVD test ready for commercial scale-up and CE-IVD certification.
NCT04062253
Data on the prevalence of hepatitis C virus (HCV) for other vulnerable groups in Madrid, such as homeless persons and migrants, are scarce, and it is now necessary to implement intervention and elimination plans. Vulnerable groups have poor access to healthcare and are therefore not systematically screened for HCV. On the occasions they are shown to be positive, subsequent follow-up in the health system and the possibility of cure are poor. The use of a mobile unit to approach vulnerable populations is essential for better characterization of risk behaviors and of the magnitude of HCV. The integration of healthcare personnel in mobile units enables counseling on prevention and intervention when needed. Primary objective Evaluate the impact of the HCV care cascade on vulnerable populations who gather at hot spots in Madrid (shantytowns, homeless shelters and places were street prostitution is practiced) by means of a multilevel outreach project. SURVEILLANCE: Active screening for HCV among vulnerable individuals in populations with a high prevalence of HCV will be carried out in hot spots in Madrid, namely, Cañada Real shanty town, mobile harm reduction units, institutions providing social assistance, public areas, homeless shelters and places where street prostitution is practiced. An agreement with the Madrid Council (MCC) is under way to provide social centers for HCV screening. A mobile unit will approach the hot spots following a predefined schedule. The mobile unit consists of a van adapted for the project and a car. HCV screening of vulnerable individuals will be performed by a nurse and an educator hired specifically for that purpose. Active HCV screening and prevention in vulnerable individuals should be a priority and a responsibility shared by both the MCC and the SERMAS (Servicio Madridleño de Salud). The investigators plan to establish an agreement with public health authorities to give continuity to this project and to carry out proactive HCV screening through integration with various centers and networks dependent on the MCC and SERMAS. The project will establish the foundations of integrated cooperation between an HCV clinic in a hospital setting and harm reduction units and other resources and networks dependent on the institutions mentioned above. As has been observed with other interventions, the functional objective of this project is to provide continuity of care from the institutions. Study Duration (in months) 12 months.
NCT03854630
The primary aim of this open-label, randomized control trial is to compare the immunogenicity at week 28 after 20µg HBV vaccine (at week 0, 4, 24) versus 40µg HBV vaccine (40-µg at week 0, 4, 24 week) among HIV-positive patients or HIV-negative MSM who were born in Taiwan after July 1986 and tested negative for all HBV serological markers. The secondary aims are to assess the safety of double-dose HBV vaccination, the proportions of high-level responders (anti-HBs antibody \>100 mIU/ml) at weeks 28 and 48, the serological responses at week 48, and incident HBV infection (indicated by appearance of anti-HBc and/or HBsAg) at week 48.
NCT04113915
Aim of the work To estimate frequency of viral HB \& C infection in ITP patients who received triple therapy in comparison with another group treated with steroids only. To explore risk factors and routes of transmission of viral HB \& C infection in ITP patients who received triple therapy and the another group treated with steroids . \- To assess preventive measures of viral HB\& C infection in the hematology ward To investigate the influence of viral HB \& C infection on clinical picture, response to treatment and side effects in ITP patients who received triple therapy or steroids.
NCT01595685
The goal of chronic hepatitis B (CHB) treatment is complete and permanent eradication of hepatitis B virus (HBV) from patient's body, which is best represented by serum HBsAg loss accompanied by undetectable serum HBV DNA level. While the most recently approved nucleos(t)ide analogues (NA) have marked antiviral potency and can induce HBV DNA undetectability in the majority of patients through prolonged treatment, NA need to be given long term, almost indefinitely, in most cases because they suppress HBV DNA only during therapy. For example, even after HBeAg-loss by a potent NA, suppression of serum HBV DNA to undetectable level is sustained only in about 23%-37% at 24 weeks off treatment. Thus, continuous therapy with NA until HBsAg clearance remains necessary in a majority of cases. The recent availability of commercial quantitative assays of serum hepatitis B surface antigen (HBsAg) has enabled quantitative HBsAg to be used as a biomarker for prognosis and treatment response in CHB. It has been suggested that HBsAg decline during lamivudine or entecavir therapy is slower and less pronounced compared to interferon treatment, despite a higher effect on HBV DNA suppression. Based on HBsAg kinetics, it has been estimated that the predicted median time to HBsAg loss in patients treated with lamivudine or entecavir is more than 30 years. Thus, treatment that can induce rapid decline of HBsAg would have clear advantage in reducing the treatment duration required to achieve HBsAg-loss. Interestingly, in a recent preliminary study, 24-weeks of treatment with telbivudine has induced HBsAg decline as comparable to pegylated interferon treatment. Although there has been no head-to-head trial comparing NAs in inducing HBsAg decline, previous studies consistently suggested that the decline of HBsAg is greater during telbivudine treatment compared with lamivudine or entecavir. Thus, in this clinical trial, the investigators will investigate whether telbivudine is more effective in inducing HBsAg decline compared with entecavir in HBeAg-positive CHB patients who have achieved undetectable serum HBV DNA by preceding entecavir treatment.
