    Sensitization of the peripheral blood lymphocytes to HBsAg and HBcAg in 51 patients with acute hepatitis B (HB) in the time course of infection, in 13 with chronic active hepatitis B (CAH) and 8 HBsAg carriers was studied by lymphocyte blastogenesis assay. In patients with mild or moderately severe forms of acute HB at the peak of the disease lymphocyte blastogenic response to HBcAg was observed; sensitization to HBsAg was lacking and could be detected only in the stage of convalescence when the specific response to HBcAg was already undetectable in most patients. No lymphocyte sensitization to HBsAg either at the peak of the disease or in convalescence was observed in patients with a lingering form of acute HB as well as in those with CAH and HBsAg carriers. At the peak of severe HB blastogenic response was demonstrated to both antigens under study but was more marked to HBcAg. Most patients with CAH showed lymphocyte blastogenic response to HBcAg. It is concluded that specific lymphocyte response to HBV antigens varies in relation to the severity and course of the infection.

    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...

    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...
