Overview
Congenital human immunodeficiency virus (HIV) infection refers to HIV transmitted from mother to child during pregnancy, childbirth, or breastfeeding, leading to significant immune system compromise from infancy. 1Diagnosis
Clinical Presentation: Includes recurrent infections, failure to thrive, and specific immunodeficiency syndromes like DiGeorge Syndrome. 1
Laboratory Tests: Assessment of lymphocyte subsets (CD4+, CD8+), immunoglobulin levels, and genetic testing for specific immunodeficiencies. 1
Imaging and Endoscopy: May be required to evaluate gastrointestinal complications, particularly in patients with neutrophil dysfunction. 1Management
Antiretroviral Therapy (ART): Essential for managing HIV infection, tailored to pediatric dosing and resistance profiles. 1
Immunoglobulin Replacement Therapy: Recommended for patients with hypogammaglobulinemia to prevent infections. 1
Surgical Intervention: Indicated for severe complications such as surgical infections in patients with neutrophil dysfunction. 1Special Populations
Pediatrics: Early diagnosis and initiation of ART are critical to prevent rapid disease progression and opportunistic infections. 1
Comorbidities: Patients with combined B and T cell disorders require vigilant monitoring for gastrointestinal symptoms and infections, often necessitating surgical intervention. 1Key Recommendations
Initiate antiretroviral therapy promptly in congenitally HIV-infected infants to optimize immune function and prevent disease progression. (Evidence: Strong 1)
Consider immunoglobulin replacement therapy for infants with congenital hypogammaglobulinemia to mitigate infection risk. (Evidence: Moderate 1)
Perform surgical interventions judiciously in patients with congenital immunodeficiencies characterized by neutrophil dysfunction due to high postoperative morbidity. (Evidence: Weak 1)References
