Immunodeficiency Diseases01:25

Immunodeficiency Diseases

1.6K
Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
There are three main causes of immunodeficiency...

Autoimmune Disorders01:29

Autoimmune Disorders

1.2K
Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents

338
Crohn's disease is an inflammatory bowel disorder marked by chronic inflammation of the GI tract. Various treatment strategies for Crohn's disease are employed, such as immunomodulatory agents, glucocorticoids, and biologics or anti-TNF therapy. Azathioprine (Imuran), a commonly used immunomodulatory drug for Crohn's disease, is converted in the body to mercaptopurine, which inhibits purine biosynthesis and cell proliferation. Both are utilized in severe cases of Inflammatory Bowel...

Antigens Involved in Adaptive Immunity01:26

Antigens Involved in Adaptive Immunity

976
An antigen is any substance the immune system identifies as foreign and potentially harmful to the body, prompting an immune response. Antigens have two functional properties: immunogenicity and reactivity. Immunogenicity is the ability of an antigen to stimulate a specific immune response. At the same time, reactivity describes the antigen's ability to react with the cells and antibodies produced in response to it.

Diseases of the Liver and Gallbladder

1.7K
Liver and gallbladder diseases are a significant health concern, with prominent conditions including cirrhosis, hepatitis, non-alcoholic fatty liver disease (NAFLD), and gallstones. Jaundice is a common manifestation of liver and biliary disease.
Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not...

Summary

Common variable immunodeficiency (CVID) impairs antibody production, yet is linked to autoimmune diseases. This case highlights autoimmune hepatitis as a liver disease manifestation in CVID patients.

Area of Science:

  • Immunology
  • Hepatology
  • Autoimmunity

Background:

  • Common variable immunodeficiency (CVID) is a primary immunodeficiency characterized by defective B-cell differentiation and impaired antibody production.
  • Patients with CVID exhibit a higher prevalence of autoimmune disorders, including various forms of liver disease.
  • Established causes of liver disease in CVID include nodular regenerative hyperplasia, granulomatous infiltration, and chronic viral hepatitis.

Observation:

  • A case of autoimmune hepatitis is presented in a patient diagnosed with Common variable immunodeficiency.
  • The patient's presentation with autoimmune hepatitis adds to the spectrum of liver pathologies observed in CVID.

Findings:

  • Autoimmune hepatitis can occur in the context of Common variable immunodeficiency, representing a less common but significant hepatic manifestation.
  • This case underscores the complex interplay between immune dysregulation in CVID and the development of autoimmune liver disease.

Implications:

  • Recognizing autoimmune hepatitis in CVID patients is crucial for accurate diagnosis and timely management.
  • Further research into the mechanisms underlying autoimmunity in CVID may elucidate shared pathways and inform therapeutic strategies.
