CSF Interleukins-12, 17 and Interferon-γ Levels in Children with Subacute Sclerosing Panencephalitis

Area of Science:

• Neurology
• Immunology
• Virology

Background:

• Subacute sclerosing panencephalitis (SSPE) is a rare, fatal neurological disease caused by a mutated measles virus.
• Primarily affecting children, SSPE leads to significant morbidity and mortality.
• Understanding the immunological markers in SSPE is crucial for potential diagnostic and therapeutic advancements.

Purpose of the Study:

• To investigate the levels of specific cytokines, including Interleukin-12 (IL-12), Interleukin-17 (IL-17), and Interferon-gamma (IFN-γ), in the cerebrospinal fluid (CSF) and serum of patients with Subacute Sclerosing Panencephalitis (SSPE).
• To explore potential correlations between these cytokine levels and the clinical stages of SSPE.

Main Methods:

• An observational study involving 24 confirmed SSPE cases (Dyken's criteria).
• Cerebrospinal fluid (CSF) and serum samples were collected.
• Interleukin levels were quantified using the Enzyme-Linked Immunosorbent Assay (ELISA) method.

Main Results:

• A statistically significant elevation of Interleukin-12 (IL-12) was observed in the CSF of stage 3 SSPE patients (p=0.02).
• This elevation in IL-12 was noted in only two patients, representing a key limitation.
• No significant differences in IL-17 and Interferon-gamma (IFN-γ) levels were found in CSF or serum across different SSPE stages.

Conclusions:

• Interleukin-12 (IL-12) may play a significant role in the pathogenesis of advanced Subacute Sclerosing Panencephalitis (SSPE).
• Further research with larger cohorts is needed to validate IL-12 as a reliable biomarker for SSPE.
• Interleukin-17 (IL-17) and Interferon-gamma (IFN-γ) do not appear to be significantly altered in SSPE patients based on this study.
