Insights
High-dose intravenous immunoglobulin (IVIg) therapy showed disappointing results for most children with infantile spasms. However, some patients experienced significant clinical and electroencephalographic improvements, suggesting potential as an auxiliary treatment.
Area of Science:
- Neurology
- Immunology
- Pediatrics
Background:
- Infantile spasms (IS) are a severe epilepsy syndrome in infants.
- West syndrome and Lennox-Gastaut syndrome are specific epilepsy classifications.
- Current treatments for IS have limitations, prompting investigation into novel therapies.
Purpose of the Study:
- To evaluate the efficacy of high-dose intravenous immunoglobulin (IVIg) as a treatment for infantile spasms.
- To assess potential correlations between treatment outcomes and immunological markers.
Main Methods:
- A prospective study involving 23 children diagnosed with infantile spasms.
- Administration of high-dose intravenous gammaglobulins (IVIg).
- Clinical and electroencephalographic assessments were performed to monitor treatment response.
Main Results:
- No significant improvement was observed in 15 out of 23 patients.
- Transient clinical and/or electroencephalographic improvement occurred in 3 patients.
- Complete normalization was achieved in 5 patients, with 4 having severe brain lesions. No correlation with immunological abnormalities was found.
Conclusions:
- Overall therapeutic results of IVIg for infantile spasms were disappointing.
- However, the occurrence of notable improvements in a subset of patients suggests IVIg may serve as an effective auxiliary treatment.
- Further research is warranted to identify patient subgroups most likely to benefit from IVIg therapy.
Abstract:
In a prospective study, 23 children with infantile spasms received intravenous gammaglobulins in high doses. 19 patients present a West syndrome. 4 older patients were included in the study because infantile spasms had preceded their Lennox-Gastaut syndrome. None of the patients had recently undergone corticosteroid therapy. No effect was observed in 15 patients, while transitory clinical and/or electroencephalographic improvement was noted in 3. Complete normalization was obtained in the remaining 5 patients, of whom 4 had severe brain lesions. No correlation existed between the therapeutic results and immunological abnormalities, a deficiency in IgG subclasses in particular. On the whole, the therapeutic results were disappointing. But the existence of some cases in which spectacular electroencephalographic and/or clinical improvement was obtained leads us to suggest that IV gamma-globulins be used as auxiliary treatment in infantile spasms.
