Summary
Six new cases of chronic granulomatous disease (CGD), a primary immunodeficiency, were diagnosed. Early-onset, severe bacterial and fungal infections were common, with diagnosis confirmed by NBT and chemiluminescence tests.
Area of Science:
- Immunology
- Pediatrics
- Genetics
Background:
- Chronic granulomatous disease (CGD) is a primary immunodeficiency affecting phagocyte function.
- Early diagnosis and management are crucial for improving patient outcomes.
- Understanding the genetic basis and clinical spectrum is vital for effective treatment.
Observation:
- Six new CGD cases were identified, representing 1.1% of primary immunodeficiencies.
- Four cases were male, two female, with X-linked and autosomal recessive inheritance patterns observed.
- Clinical manifestations, including severe bacterial and fungal infections, appeared before age two, earlier and more severely in males.
Findings:
- Common infections included liver, lung, and skin abscesses, lymphadenitis, and mastoiditis; osteomyelitis was absent.
- Isolated pathogens comprised various bacteria (Staphylococcus, Salmonella, Serratia, Pseudomonas, Enterococcus) and fungi (Candida, Aspergillus, Trichopyton).
- Diagnostic indicators included leukocytosis, elevated acute phase reactants (PCR, VSG), hypergammaglobulinemia, and high LB/LT4 levels, confirmed by NBT and chemiluminescence tests.
Implications:
- This study highlights the prevalence and diverse clinical presentations of CGD in pediatric patients.
- Accurate diagnosis through NBT and chemiluminescence tests is essential for timely intervention.
- Further research into genetic factors and treatment strategies can improve the management of CGD.
