Active clinical trials for "Hepatitis A"

Recently,surprisingly and unexpectedly increased aggressiveness and high rates of HCC recurrence (28%(16/58) and 29%(17/59), respectively) have been reported in patients who cleared HCV with DAAs after achieving a complete response to resection or local ablation within only 6 months of therapy. The authors hypothesized that the rapid eradication of HCV and control of liver inflammation would impact anti-tumoral immune control, which in turn might contribute to the neoplastic cells proliferation. Conversely, three independent prospective French cohorts failed to reveal an increased risk of HCC recurrence after DAAs treatment in CHC patients after receiving curative cancer treatments.Although the impact of DAAs treatment on the rate of HCC occurrence or recurrence still remain unclear, it would be more important to pay attention to the immunological changes of CHC patients treated with DAAs.Up to now, little was known about the immunological changes of chronic hepatitis C (CHC) patients treated with direct-acting antiviral agents (DAAs), here we try to explore the effect of antiviral treatment of CHC patients with DAAs on the frequency of monocytes, NK cells and cytokines that promote their activation.

The REP 301 treatment protocol involved the treatment of patients with chronic hepatitis B / hepatitis D co-infection with two agents: REP 2139-Ca and pegylated interferon (peg-IFN). In this protocol, similar reduction/clearance of serum HBsAg and improved response to immunotherapy were observed in addition to clearance of serum HDV RNA. The REP 301 protocol was designed to include a 24 week follow-up period after treatment, however given the strong antiviral response against HBV and HDV infection in these patients, it is now important to extend the follow-up period in these patients to monitor over a longer period after treatment the safety and efficacy combined REP 2139-Ca / peg-IFN treatment in patients in the REP 301 protocol.

The World Health Organization recommends that all high endemic countries for HBV infection based their mother to child transmission prevention strategies on vaccination of all children and administration of immunoglobulins (HBIG) to infants born to infected mothers in the first 24 hours after birth. Lack of access to antenatal screening and to HBIG significantly results in failure of this strategy in many countries. Moreover, despite sero-vaccination, 10 to 15% of infants of mothers that are positive for HBsAg and HBeAg are still infected, as high levels of HBV replication occurring in the third quarter of pregnancy act as a major risk factor. The objective of this study is to assess the effectiveness of an operational strategy to prevent HBV mother-to-child transmission (MTCT) in Cambodia based on the use of rapid tests HBs Ag and HBe Ag to screen HBV infection and a treatment by TDF for patients with a positive HBeAg test with a "test and treat" strategy for those seen for Antenatal Care (ANC) from 24 weeks of amenorrhea. In all cases, vaccination of the newborn will be carried out according to the national protocol in Cambodia i.e. 4 injections at 24 hours, 6, 10 and 14 weeks of age. A phase IV multicenter observational and interventional non randomized prospective study will be conducted in 4 maternity in Cambodia. The primary outcome will be the proportion of active HBV infection in new-born at 6 months of life estimated by HBs Ag positivity. The study will aim to document the acceptability and the operational implementation of the study using rapid tests usable in all health centers and a drug available in all the country thanks to HIV national program. The results will be helpful for Cambodian government in order to implement guidelines and algorithm follow-up for HBV-infected pregnant women.

Several factors are barriers to effective Hepatitis C care: 1) The majority of Hepatitis C Virus (HCV)-positive patients (45-85 percent) are unaware that they are infected; 2) Only a small minority of those in need of treatment receive it; 3) Members of minorities and older patients are even less likely to receive needed care; and 4) Until recently, even those who were treated had a low chance of clearing the virus or achieving cure; 5) It is possible that older attitudes and expectation of futility might continue to persist among patients and provider in primary care settings. Community Health Centers are often the most culturally appropriate and accessible choices, particularly for underserved populations, with the benefit of ongoing trust and relationships with patients. Therefore, these can be ideal places to deliver complex HCV care if they possess the needed expertise. However, most community-based primary care and community health centers lack access to Hepatitis C evaluation and treatment services, leading to a major public health problem. Thus, investigators propose to implement and evaluate a pragmatic trial to implement and evaluate a multi-disciplinary model for HCV treatment at Currently, the treatment initiation rates at each of these sites is estimated as less than 10%. The investigators hypothesize that our project will increase the rate of participation in all the steps of the HCV care cascade and ultimately lead to more than doubled rates of treatment uptake

This was a long-term follow-up study to evaluate the durability of sustained virologic response (SVR), persistence of direct-acting antiviral agent (DAA) resistance, and clinical outcomes for participants who received glecaprevir (ABT-493) and/or pibrentasvir (ABT-530) in prior AbbVie Phase 2 or 3 clinical studies for the treatment of chronic hepatitis C virus (HCV) infection.

Globally, hepatitis B virus (HBV) infection is the most common form of chronic hepatitis. There are still a lot of uncertainties on how infants acquired HBV leading to the development of chronic HBV infection despite active and passive immunoprophylaxis. The investigators would like to carry out a prospective study to answer the following questions: the paternal, maternal and obstetric factors leading to immunoprophylaxis failure the prevalence of immunoprophylaxis failure in Hong Kong

The interferon-free combination regimen of paritaprevir/ritonavir/ombitasvir with or without dasabuvir (ABBVIE REGIMEN) ± ribavirin (RBV) for the treatment of chronic hepatitis C (CHC) has been shown to be safe and effective in randomized controlled clinical trials with strict inclusion and exclusion criteria under well-controlled conditions. This observational study is the first effectiveness research examining the ABBVIE REGIMEN ± RBV, used according to the local label, under real-world conditions in Greece in a clinical practice patient population.

Chronic hepatitis C infection is a global worldwide health problem with an increasing burden year-by-year, particularly in areas with a high endemicity like Egypt . The World Health Organization estimates that approximately 200 million people worldwide are infected with hepatitis c virus. In Egypt, it was estimated that 15 % of Egyptians have serologic evidence of hepatitis C viral infection .

The aim of the study is to evaluate in clinical practice the efficacy and safety of ombitasvir/paritaprevir/ ritonavir and dasabuvir administered for 8 weeks in treatment-naïve participants with genotype 1b hepatitis C virus (HCV).

This study aims at estimating the prevalence of chronic hepatitis B virus (HBV) infection in rural Senegal (area of Niakhar) and at evaluating the associated burden in terms of both health-related and socio-economic consequences.
