Summary
Selective IgA deficiency, the most common primary immunodeficiency, increases risks for infections, allergies, autoimmune conditions, and cancers in children. This study highlights these associations in Israeli children.
Area of Science:
- Immunology
- Pediatrics
- Clinical Medicine
Background:
- Selective IgA deficiency is the most common primary immunodeficiency worldwide.
- Understanding its clinical and immunological spectrum in pediatric populations is crucial.
Purpose of the Study:
- To evaluate the clinical and immunological characteristics of selective IgA deficiency in Israeli children.
- To identify potential associations with other health conditions.
Main Methods:
- Retrospective analysis of 63 children diagnosed with IgA deficiency between 1987 and 2005 in Israel.
- Mean follow-up of 10.6 years per child.
- Data collection on diagnoses, infections, allergies, autoimmune diseases, and malignancies.
Main Results:
- The average age at diagnosis was 10.5 years.
- Infectious diseases (pneumonia, ear infections) affected 39.7% of patients.
- Allergic diseases (31.7%), autoimmune conditions (20.6%), and malignancies (4.8%) were also observed.
- Malignancy association is a novel finding in this context.
Conclusions:
- Selective IgA deficiency is linked to increased risk of infections, allergic diseases, and autoimmune conditions in children.
- A potential association with malignancy warrants further investigation.
- Early diagnosis and monitoring are essential for managing associated risks.

01:15Transcytosis of IgG
Transcytosis is the process in which molecules are internalized by endocytosis, transported across the cell, and released through exocytosis from the opposite end of the cell. Molecules such as insulin, immunoglobulins, and certain nutrients are transferred through the recycling endosomes by recycling and transcytosis.
IgG molecules from a mother undergo transcytosis starting around 13 weeks of gestation. The amount of IgG transferred and entering the fetal blood circulation increases with...

01:30Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy
Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the colonic...

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.
There are three main causes of immunodeficiency disorders...

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...

01:27Glucose Transporters
Glucose transporters facilitate the transport of glucose across the cell membrane. In addition to glucose, some glucose transporters can also aid the movement of other hexoses such as fructose, mannose, and galactose.
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:

01:12Giardiasis
Giardiasis is a globally prevalent intestinal infection caused by the protozoan parasite Giardia duodenalis (also known as G. lamblia or G. intestinalis). This flagellated protozoan is the most frequently identified intestinal parasite in the United States and worldwide. Transmission primarily occurs via the fecal-oral route, with infection arising from ingestion of water or food contaminated with cysts. Individuals in low-resource settings, international travelers, outdoor enthusiasts, daycare...
