    Insights

    The 2013 Croatian Guidelines update diagnostic strategies for viral hepatitis B and C. Key updates include HBV DNA quantification and IL-28B genotyping for predicting treatment response in Hepatitis C patients.

    Area of Science:

    • Hepatology
    • Virology
    • Clinical Diagnostics

    Background:

    • The 2013 update of Croatian Guidelines for Viral Hepatitis addresses advancements in diagnosing Hepatitis B and C.
    • Current diagnostic algorithms require refinement to incorporate new serological markers and molecular assays.

    Purpose of the Study:

    • To summarize recent developments in the diagnosis of viral hepatitis B and C.
    • To provide updated recommendations for diagnostic workup and monitoring.

    Main Methods:

    • Review of serological markers for Hepatitis B (HBsAg, anti-HBc, anti-HBs) and their sequential analysis.
    • Utilizing HBV DNA quantification and HBsAg quantification for differentiating disease states and monitoring treatment.
    • Employing real-time PCR for HBV DNA detection and quantification.
    • Implementing anti-HCV antibody screening assays followed by HCV RNA or capsid antigen testing.
    • Recommending molecular assays for monitoring viral kinetics in Hepatitis C treatment.
    • Considering IL-28B genotyping as a predictor of sustained virologic response (SVR).

    Main Results:

    • Hepatitis B diagnosis involves initial testing of HBsAg, anti-HBc, and anti-HBs, followed by HBV DNA quantification.
    • HBsAg quantification aids in differentiating inactive carriers from active chronic hepatitis B and monitoring treatment.
    • HCV diagnosis requires antibody screening, confirmed by HCV RNA or capsid antigen testing.
    • Molecular assays are recommended for viral kinetics monitoring in chronic Hepatitis C.
    • IL-28B genotyping is recommended for predicting treatment outcomes in chronic Hepatitis C, particularly for treatment-naïve patients.

    Conclusions:

    • Updated diagnostic algorithms for Hepatitis B and C are essential for effective patient management.
    • HBV DNA and HBsAg quantification play crucial roles in diagnosing and monitoring Hepatitis B.
    • IL-28B genotyping is a valuable tool for personalizing Hepatitis C treatment strategies.

    Hepatitis

    Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver.

    Viral Hepatitis I: Introduction

    Viral hepatitis is an inflammatory condition of the liver caused by infection with hepatotropic viruses, most commonly hepatitis A, B, C, D, and E. Despite variations in structure and transmission, all viruses mentioned infect hepatocytes and provoke immune responses that can hinder liver function. Additionally, some non-hepatotropic viruses can also lead to hepatic inflammation.Hepatitis A VirusHepatitis A virus (HAV) is transmitted through the fecal–oral route, typically by ingestion...

    Cytomegalovirus Disease

    Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...
