Summary
Prognosis in acute viral hepatitis is linked to immune cell counts. Lower T cell numbers in patients with severe hepatitis, including pregnant individuals, correlated with poorer outcomes, suggesting a role for cell-mediated immunity.
Area of Science:
- Immunology
- Hepatology
- Virology
Background:
- Acute viral hepatitis can lead to severe complications, including coma.
- Immune system dysregulation is implicated in disease severity and patient outcomes.
Purpose of the Study:
- To investigate the relationship between peripheral blood lymphocyte subsets and prognosis in patients with acute viral hepatitis.
- To assess the role of cell-mediated immunity in determining the outcome of severe acute viral hepatitis.
Main Methods:
- Peripheral blood lymphocytes were analyzed in 41 patients with acute viral hepatitis (grades III-IV coma).
- Included 16 pregnant patients in their third trimester.
- Assessed absolute lymphocyte count, T cell number, B cell count, and migration inhibition test with BCG antigen.
Main Results:
- Patients who succumbed to the disease showed significantly reduced absolute lymphocyte counts and T cell numbers compared to survivors.
- B cell counts were comparable between survivors and non-survivors.
- Migration inhibition tests with BCG antigen were normal in all patients.
Conclusions:
- A decrease in T cells, crucial for cell-mediated immune reactions, is associated with a poorer prognosis in acute viral hepatitis.
- Immune cell profiling may offer prognostic insights for severe acute viral hepatitis.

01:18Lymphoid Cells and Tissues
3.4K
Lymphoid cells and tissues are integral to the immune system, which is crucial in maintaining our body's defense against harmful pathogens. They form the building blocks of lymphoid organs, which include the spleen, thymus, and lymph nodes.
Lymphoid cells consist of various types of immune system cells. These include B and T lymphocytes, which are responsible for producing antibodies and killing infected cells, respectively. Dendritic cells act as messengers between the innate and adaptive...

Primary lymphoid organs are pivotal in the formation, development, and maturation of lymphocytes, the white blood cells that serve as the backbone of our immune system. This crucial function underscores their fundamental role in maintaining our overall health and immunity. The two primary lymphoid organs of prime importance are the red bone marrow and the thymus.
The red bone marrow is a soft, spongy tissue nestled in the interior of long bones such as the humerus and femur. It is the site...

01:23Cells of the Adaptive Immune Response
6.9K
The T and B lymphocytes of the adaptive immune system develop from common lymphoid progenitor cells in the bone marrow. These progenitors give rise to precursors that eventually develop into both T and B lymphocytes. As these precursors mature, they gain the ability to detect and respond to foreign antigens in the body, a process known as immunocompetence. Additionally, these precursors acquire self-tolerance, a process that ensures they do not react to self-antigens. This intricate system...

2.4K
The immune system's response to viral infections is a complex and coordinated process involving natural killer (NK) cells, T cell-mediated responses, and antibody-mediated responses.
NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...

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 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...
