[Basics of primary immunodeficiencies].

Area of Science:

• Immunology
• Genetics
• Pediatrics

Background:

• Primary immunodeficiencies (PIDs) are inherited disorders stemming from immune system defects.
• Manifestations include recurrent infections, malignancies, autoimmunity, and allergies, often appearing in childhood.
• Antibody immunodeficiencies are the most common PID type in adults.

Purpose of the Study:

• To highlight the importance of early diagnosis of primary immunodeficiencies.
• To inform primary care physicians about PID recognition and management.
• To emphasize the impact of delayed diagnosis on patient prognosis.

Main Methods:

• Review of PID characteristics, including etiology, manifestations, and inheritance patterns.
• Discussion of diagnostic approaches, such as complete blood count and immunoglobulin quantification.
• Analysis of factors contributing to diagnostic delays.

Main Results:

• PIDs are genetic disorders, frequently autosomal recessive and more common in males and children.
• Common PIDs include respiratory tract infections, abscesses, candidiasis, and diarrhea.
• Diagnostic delays arise from underestimating recurrent infections or assuming they are childhood-exclusive.

Conclusions:

• Early recognition and diagnosis of PIDs by primary care physicians are essential.
• Timely intervention leads to improved treatment outcomes and prognosis.
• Increased awareness can mitigate diagnostic delays and improve patient care.
