Summary
Common variable immunodeficiency (CVID) patients can be classified by T lymphocyte activation levels. This distinction helps identify patients with autoimmune issues versus those with only infections, aiding future research.
Area of Science:
- Immunology
- Clinical Medicine
Context:
- Common variable immunodeficiency (CVID) is a primary immunodeficiency.
- CVID often presents with recurrent bacterial infections, but autoimmune and granulomatous manifestations can occur.
Purpose:
- To investigate clinical manifestations and lymphocyte activation in CVID patients.
- To explore potential correlations between T lymphocyte activation and clinical phenotypes in CVID.
Summary:
- This retrospective study analyzed 17 CVID patients, evaluating lymphocyte activation via HLA-DR expression.
- Patients with activated T lymphocytes (7/12) exhibited autoimmune or tumoral conditions, while those without (5/12) presented solely with infections.
- Common findings included recurrent respiratory infections, with some patients experiencing autoimmune diseases, splenomegaly, or granulomas.
Impact:
- Classifying CVID patients by T lymphocyte activation may enable the formation of homogeneous groups for genetic and functional studies.
- This approach could uncover heterogeneous molecular abnormalities underlying CVID.

01:26Factors Affecting the Risk of Infection
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin create...

01:20Special Features of Adaptive Immunity
The adaptive immune system, a crucial component of the overall immune response, offers a highly specialized defense against pathogens. It involves specific cell types and features, enabling it to combat infections effectively and efficiently.
The primary cell types involved in adaptive immunity are T cells and B cells. Each type has a unique role in defending the body against pathogens. T cells are responsible for cell-mediated immunity. They identify and eliminate infected cells directly,...

01:22Development of Immunocompetence
The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...

01:25Immunodeficiency Diseases
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.

01:28Infectious Diseases and Their Occurrence
Infectious diseases appear in populations through various transmission patterns, influenced by pathogen characteristics, population immunity, environmental conditions, and social behavior. Understanding these patterns is essential for effective public health surveillance and intervention. These categories—sporadic, outbreak, epidemic, pandemic, and endemic—help frame the nature and scope of disease events.Sporadic diseases occur irregularly and infrequently, without a predictable temporal or...
01:27Cytomegalovirus 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...
