Gene Therapy Evaluation
Emerging curative option for eligible patients with identified genetic mutations. Clinical trial participation may be available for appropriate candidates.
Additional treatment options
Granulocyte Colony-Stimulating Factor
In selected immunodeficiencies with neutropenia, G-CSF stimulates white blood cell production. Reserved for cases with documented neutrophil dysfunction.
medicationChronic Illness Counseling
Psychological support addresses anxiety, depression, and quality-of-life concerns common in patients with chronic immunodeficiency. Coping strategies and support groups provide valuable resources.
psychologicalComprehensive Infection Monitoring
Regular clinical assessments and laboratory screening detect infections early before complications develop. Includes periodic cultures, imaging, and inflammatory markers.
