Cell-mediated immunity in Hurler's syndrome
Allergologia Et Immunopathologia
|March 1, 1975
Summary
Cell-mediated immunity in Hurler's syndrome (Gargoylism) appears normal in some patients, but a delayed or partial immune defect may occur in younger individuals. Further investigation into immune mechanisms in Hurler's syndrome is warranted.
Area of Science:
- Immunology
- Genetics
- Pediatrics
Background:
- Hurler's syndrome (Gargoylism) is a rare genetic disorder.
- Cell-mediated immunity plays a crucial role in defending against infections.
- The immune status of individuals with Hurler's syndrome requires further elucidation.
Purpose of the Study:
- To investigate cell-mediated immunity in three brothers diagnosed with Hurler's syndrome.
- To assess immune responses to various stimuli, including infectious antigens, PHA, and DNCB.
- To explore potential immune defects associated with Hurler's syndrome in early life.
Main Methods:
- Evaluation of immune responses in three patients with Hurler's syndrome.
- Testing responses to infectious antigens.
- Assessing phytohemagglutinin (PHA) stimulation and 2,4-dinitrochlorobenzene (DNCB) sensitization.
Main Results:
- Two brothers exhibited normal responses to infectious antigens, PHA stimulation, and DNCB sensitization.
- The oldest brother showed delayed DNCB sensitization (18 days).
- The youngest brother displayed a normal PHA response but a weak cutaneous reaction to oidiomycin and no DNCB sensitization.
Conclusions:
- A retarded and partial defect in cell-mediated immunity may be present in young patients with Hurler's syndrome.
- Immune system development might be affected in Hurler's syndrome.
- These findings suggest the need for careful monitoring of immune function in affected children.
