[DiGeorge syndrome--significance of early diagnosis in cellular immunodeficiency]
Insights
Di George syndrome, a congenital disorder affecting thymus and parathyroid development, can lead to hypocalcemia and immunodeficiency. This case highlights the importance of early diagnosis and management in affected infants.
Area of Science:
- Developmental biology
- Immunology
- Pediatrics
Background:
- Di George syndrome arises from abnormal development of pharyngeal pouch derivatives.
- Key features include thymus aplasia, parathyroid hypoplasia, and cardiovascular defects.
- Clinical manifestations include hypoparathyroidism and severe infections due to immunodeficiency.
Abstract:
Di George syndrome is caused by anomalous development of the organs arising from the third and fourth pharyngeal pouches and results in congenital aplasia of the thymus, aplasia or hypoplasia of the parathyroid glands and cardiovascular malformations. Clinically, affected children show hypoparathyroidism and, because of depressed cell-mediated immunity, serious bacterial, viral and fungal infections. We present an infant, aged 6 weeks, with convulsions due to hypocalcemia, in which cell-mediated immunodeficiency was detected. Additionally diagnostic and therapeutic possibilities in DiGeorge syndrome are shown.
