[Selective IgA defect. Clinical importance for stomatology].

Area of Science:

• Immunology
• Clinical Medicine
• Dentistry

Context:

• Selective IgA immunodeficiency (SIgAD) is the most common primary immunodeficiency.
• Patients often present with recurrent sinopulmonary infections, allergies, and autoimmune disorders.
• Diagnosis is frequently delayed, with a mean age of 42 years in this cohort.

Purpose:

• To describe the clinical manifestations of SIgAD in adult women.
• To highlight the dental implications and complications associated with SIgAD.
• To emphasize the need for increased awareness among dental professionals regarding SIgAD.

Summary:

• A study of 6 women with SIgAD over 2-13 years revealed delayed diagnosis despite chronic infections.
• One case presented with a complicated fistula post-molar extraction, underscoring dental diagnostic challenges.
• No significant differences in periodontitis or caries were observed compared to the general population.

Impact:

• Increased awareness of SIgAD among dentists can lead to earlier diagnosis and intervention.
• Understanding potential complications can improve patient outcomes and prevent systemic issues.
• Highlights the importance of interdisciplinary collaboration between immunologists and dentists.
