Insights
Primary immunodeficiency diseases (PID) in children often present with recurrent infections and developmental delays. Early immunologic testing is crucial for timely diagnosis and treatment of pediatric PID.
Area of Science:
- Pediatric Immunology
- Clinical Genetics
- Infectious Diseases
Context:
- Primary immunodeficiency diseases (PID) are a group of genetic disorders affecting the immune system.
- Early diagnosis and management are critical for improving outcomes in affected children.
Purpose:
- To summarize the clinical features of primary immunodeficiency diseases (PID) in children.
- To highlight the importance of early immunologic testing for pediatric PID.
Summary:
- A retrospective study analyzed 35 children with PID, identifying various subtypes including combined T- and B-cell immunodeficiency, X-linked agammaglobulinaemia, selective IgG subclass deficiency, common variable immunodeficiency, and chronic granulomatous disease.
- Common manifestations included recurrent fever, respiratory and digestive tract infections, and growth delays. Treatment involved gamma-globulin transfusion and anti-infective therapy, with most patients showing clinical improvement.
Impact:
- This study underscores the need for considering PID in children with recurrent infections, autoimmune conditions, or poor response to antibiotics.
- Prompt immunologic evaluation can lead to earlier diagnosis and more effective management of pediatric PID, improving patient outcomes.
Objective:
To summarize clinical features of primary immunodeficiency diseases (PID) in children.
Methods:
The clinical data of 35 children with PID from September 2005 to December 2008 were studied retrospectively, including illness history, birth history, family history, clinical manifestations, laboratory findings, diagnosis, treatment and outcome.
Results:
Of the 35 cases of PID, 6 cases were confirmed with combined T- and B-cell immunodeficiency, 4 cases with X-linked agammaglobulinaemia, 22 cases with selective IgG subclass deficiency, 1 case with common variable immunodeficiency and 2 cases with chronic granulomatous disease. All cases had fever and recurrent infections. Respiratory and digestive tract infections were the most common clinical manifestation. Some of the PID cases lagged behind the normal children of the same age in growth and development. Human gamma-globulin transfusion and anti-infection therapy were administered. Two patients discontinued the therapy, one was transferred to the other hospital and the other 32 patients were discharged following improvement in clinical symptoms.
Conclusions:
PID should be considered in children who suffer from recurrent infections and autoimmune diseases or do not respond to long-term use of antibiotics. Immunologic tests should be done as early as possible for the children.

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.
