NCT ID: NCT06360484 Completed - Hepatitis B Clinical Trials

Prevalence and Clinical Characterization of Hepatitis D Virus (HDV) Infection Among Sudanese Patients With Hepatitis B Virus

Start date: June 1, 2022
Phase:
Study type: Observational

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

NCT ID: NCT05962307 Completed - Hepatitis D Clinical Trials

Efficacy and Safety of Bulevirtide (BLV) Therapy in HDV Chronic Hepatitis (CHD) in Italy

HEP4Di
Start date: April 1, 2023
Phase:
Study type: Observational

Spontaneous, pharmacological observational, no-profit, retrospective, multi-center. This study was designed to get a "real-life" snapshot across several Italian Hepatology centers. All HDV patients are followed up according to EASL 2017 guidelines. This allows uniformity on the indication for antiviral treatment and management of that antiviral therapy. No off-label medications are used. All data are retrievable from the patient's medical record. In addition, clinical and biochemical data from patients at month 0, 1, 2, 4, 6 and 12 of treatment, and otherwise within the study period, will be collected retrospectively/longitudinally. The primary objective of the study is to describe the virological response to BLV in all patients starting BLV therapy, defined as a >2 Log decline in HDV-RNA or undetectable HDV-RNA (using the Robogene 2.0 quantitative kit, LLQ <6 IU/ml) at month 12 of therapy. All patients with active HDV chronic hepatopathy (quantifiable HDV-RNA) who initiated treatment with BLV 2 mg/day during the study period at the S.C. Gastroenterology and Hepatology (Fondazione IRCCS Ca' Granda Ospedale Maggiore Policlinico) and at participating centers, and who met the inclusion criteria and none of the exclusion criteria.

NCT ID: NCT05883891 Completed - Alcoholic Hepatitis Clinical Trials

Prothrombin Time Predicts Steroid Response in Severe Alcoholic Hepatitis.

AH2023
Start date: June 1, 2017
Phase:
Study type: Observational

Alcoholic hepatitis (AH) is the most severe form of acute alcohol-related liver disease. Maddrey's discriminant function (mDF) >32 defines the severe form of AH, which is associated with a high mortality. Corticosteroid therapy (CS) represents the main medical treatment that may reduce short-term mortality. Lille score at day 7 assesses the therapeutic response to steroid therapy. At present, no parameters able to predict the response to steroid therapy have been highlighted. The mDF depends mainly on prothrombin time (PT). Aim of the present study was to evaluate if the PT value could predict the response to CS in severe AH (sAH).

NCT ID: NCT05840640 Completed - Alcoholic Hepatitis Clinical Trials

Granulocyte Colony Stimulating Factor Four Week Plus N-Acetyl Cysteine in Severe Alcoholic Hepatitis

Start date: October 1, 2017
Phase: Phase 4
Study type: Interventional

Alcoholic hepatitis is related to very high mortality rate. About 40% of the patients died within first 6 months after the detection of the clinical syndrome. Therefore, it is very essential for proper diagnosis and early treatment . In response to acute or chronic liver damage, bone marrow derived stem cells can spontaneously populate liver and differentiate into hepatic cells. Animal and human studies suggested that injured hepatocyte may be replaced by pluripotent bone marrow cells. However, this hepatocyte repopulation is highly dependent on varieties of liver injury and therapeutic conditions. The studies have suggested Granulocyte-colony stimulating factors (G-CSF) can regenerate hepatocyte by fusing with hematopoietic cells, thereby enhancing the liver histology and survival rate. G-CSF is a cytokine capable to regulate a number of functions in neutrophils. In three recent studies mobilization of bone marrow stem cells induced by G-CSF was observed in patients with alcoholic hepatitis. In two of these studies there was a survival benefit with the use of G-CSF. Alcoholism leads to decrease in endogenous antioxidant potential. Alcoholic liver disease (ALD) patients show low endogenous antioxidants. Chronic ethanol consumption cause selective deficiency in the availability of reduced glutathione (GSH) in mitochondria has been reported. This is due to impaired functioning of GSH transporter from cytosol to mitochondrial matrix. The effect on glutathione replenishing potential by N-acetyl cysteine (NAC) can be used to reduce oxidative stress, which also has excellent safety profile. Therefore, NAC can be used for severe alcoholic hepatitis treatment due to its therapeutic potential factor. NAC also inhibit apoptosis and pro-inflammatory cytokine production. In a study high doses of intravenous N-acetyl cysteine therapy for 14 days conferred neither survival benefits nor early biological improvement in severe acute alcoholic hepatitis patients with adequate nutritional support.However, these results must be viewed with caution, since the study suffered from a lack of power. In a recent study, NAC and corticosteroids combination therapy benefits among patients with severe acute alcoholic hepatitis in 1 month survival, although the final outcome at 6 month survival was not improved. There are no studies on the use of combination therapy of 4 weeks of NAC plus G-CSF in patient with severe alcoholic hepatitis. Therefore the investigators plan to study the safety and efficacy of combination therapy of G-CSF and 4 weeks of NAC in the patients with alcoholic hepatitis.

NCT ID: NCT05823584 Completed - Clinical trials for Hepatocellular Carcinoma

Cell-free DNA From Junction of Hepatitis B Virus Integration in HCC Patients for Monitoring Post-resection Recurrence

Start date: December 22, 2019
Phase:
Study type: Observational

HBV DNA integration has been found in the chromosomes of about 90% of HBV-related HCC and the integration site is unique to individual HCC. The virus-host chimera DNA (vh-DNA) from HBV integration sites in HCC a reliable evidence even in the patient with a tiny tumor which is not large enough to be detected by the image scan. The goal of this observational study is to compare the prediction ability of vh-DNA with the other biomarkers for monitoring the recurrent of HBV-related HCC. The main questions that aim to answer are the sensitivity and specificity of vh-DNA/AFP/ALP-L3/PIVKA-II/TERTC2280 when the gold standard is the guideline of HCC diagnosis. The surgical tissues and plasma samples from the participants would be collected undergoing the HCC recession surgery when joining the study at the beginning, in order to identify the HBV integration in tumor by Capture NGS and quantify the specific vh-DNA in plasma by ddPCR as personalized biomarkers for minimal residual disease (MRD) monitoring. Moreover, the consistency of vh-DNA from tumor will be validated by pre-operative plasma. Then the participants will be asked to performed the visit at 2, 5, 8, 11, 14 months after the HCC recession surgery. The plasma sample for vh-DNA/AFP/ AFP-L3/ PIVKA-II/ TERTp C228T testing and the image data from ultrasound, CT or MRI would also be collected at these visits. When the vh-DNA testing result is positive and there is no recurrence at 14 months after the HCC recession surgery, some participants will be asked to followed at 17, 20 months. Researcher will compare the sensitivity, specificity and predict day of vh-DNA with AFP/ AFP-L3/ PIVKA-II/ TERTp C228T as a biomarker for HCC surveillance. The true value of this novel HBV chimera vh-DNA will be revealed. The results will also support to use for monitoring post-operative recurrence. In addition, the investigators will explore the performance of TERTp C228T mutation from non-HBV HCC patients. As a different target of ctDNA for HCC, TERTp C228T will be identified using surgical tissues from HCC patients, and plasma samples from the same patient before/after operation will be tested by ddPCR . It will be evaluated that TERTp C228T is predictive or not for recurrence monitoring of HCC.

NCT ID: NCT05791851 Completed - HIV Infections Clinical Trials

Heplisav-B Revaccination for Hepatitis B Vaccine Nonresponders

HBR2
Start date: October 23, 2019
Phase:
Study type: Observational

The goal of this natural history study is to examine the immune responses to the Heplisav-B vaccine in Veterans living with HIV who were non-responders to prior HBV vaccination. A comparison group of HBV vaccine nonresponders without HIV infection will be enrolled to characterize the HIV-associated immune alterations that affect vaccine response. The investigators hypothesize that TLR9-mediated innate immune stimulation with Heplisav will elicit HBV seroprotection despite prior vaccination failures in persons living with HIV, compared to HIV uninfected individuals. Participants eligible for Heplisav-B vaccination will be asked to provide blood samples at multiple timepoints before and after their vaccination.
