Hepatitis CTo determine the relapse rate at 24 weeks follow up in Hepatitis C Virus Genotype 1 Low Viral Load (HCV LVL G1) patients treated for 24 weeks with Peg Intron and Rebetol who are Hepatitis C Virus-Ribonucleic Acid (HCV-RNA) negative at treatment week 4 and week 24. To determine the proportion of patients (%) with sustained virological response at 24 weeks post follow up treatment.

A Controlled Prospective Study of Transfusion-Associated Hepatitis
HepatitisThis protocol represents a continuation of a series of prospective studies to define the incidence and etiology of transfusion-associated hepatitis (TAH) and to examine the impact on TAH of various modifications in the selection of blood donors. The primary goal of the study will be to determine TAH incidence after the institution of a variety of interventive measures to exclude hepatitis and AIDS virus carriers: including surrogate assays (ALT, anti-HBc), a specific assay for the hepatitis C virus (HCV), a specific assay for the human immunodeficiency virus (HIV) and intensified donor questioning for high-risk behavior patterns. There is high probability that the exclusion of donors at high risk for AIDS transmission will also exclude donors at high risk for hepatitis transmission. Incidence data obtained in the study will be enhanced by the simultaneous follow-up of a control population undergoing identical surgical procedures, but receiving no blood or only autologous blood. This control population, made possible by the recent dramatic increase in the amount of autologous blood utilized, will allow for a clear distinction between transfusion-associated hepatitis and that due to nosocomial transmission or other background causes of hepatocellular inflammation in cardiac surgery patients.

Hepatocyte-specific Versus Extracellular Contrast Agents for Liver MRI: Prospective, Intra-individual...
Chronic HepatitisLiver CirrhosisAdult patients with chronic hepatitis B and cirrhosis of any etiology who are found to have suspected liver cancer are potentially eligible for the study. All enrolled patients will undergo two MRI scans using two different contrast agents. The type of contrast agent for the 1st MRI will be performed using hepatocyte-specific contrast agent. The participant will undergo the 2nd MRI using extracellular contrast agent. The MRI examinations will be independently interpreted by two different radiologists. The radiologists will evaluate focal hepatic lesions and categorize them according to the LI-RADS v2018 and EASL 2018. Once the diagnosis is made, the participants will be provided with the standard of care. After the initial treatment, the participants will be followed up with multi-phasic dynamic contrast-enhanced CT every 3 or 6 months for at least 2 years. Based on the prospectively written radiology reports, the diagnostic performances will be calculated and compared between MRI with hepatocyte-specific contrast agent and MRI with extracellular contrast agent, using the pathology and clinical criteria as the reference standard.

Anticipated and Perceived Benefits Following Hepatitis C Treatment
Hepatitis CHepatitis C1 moreThe study is both qualitative and quantitative, gathering patient's perceptions of HCV treatment benefits before and after HCV treatment by administering surveys and conducting in-depth qualitative patient interviews. The study seeks to understand all anticipated and actual benefits patients perceive before and after viral eradication.
