Predicting onset and remission of infantile spasms by pairing clinical signs and a disease biomarker
CSF-GABA

Background:
Infantile spasms or West Syndrome (WS) represents one of the most devastating seizure disorders of pediatric
epilepsy and are more frequently associated with poor intellectual outcomes. Early diagnosis with prompt initiation of
treatment is key to effective control of spasms and may improve patient outcomes. Although the onset of WS is known to
typically happen between ages 4-8 months, very little is known about the precise neuromechanical triggers or biochemical
disease markers that herald its onset or remission. Diagnosis of WS usually involves visual observation of spasms and
confirmation of hypsarrhythmia (disorganized wave-pattern) with an Electroencephalogram (EEG). Studies have identified
a pre-hypsarrhythmia window of 3-6 weeks characterized by slow spikes that increase in frequency as condition deteriorates.
However, the cutoff point to initiate treatment and avert disease could not be concisely defined. Also, decreased levels of brain
γ-Amino Butyric Acid (GABA) have been associated with seizures, but exploitation of this knowledge in disease management
was limited by several challenges including the absence of a reliable method for measuring GABA.
Method:
We postulate that pairing a test for CSF-GABA concentration with clinical signs observed would greatly enhance
chances to accurately predict spasms prior to onset. We plan a prospective study of CSF GABA levels as an indicator in the
onset/development and remission of WS using our new method.
Findings:
Using a novel LC-MS/MS method we recently developed for quantifying GABA in small amounts of CSF, we found
that the mean GABA concentration in CSF from infants with seizures (n=16) was significantly lower (P=3.44e-12) compared
to their age-matched controls (n=43), suggesting that susceptible infants have significantly lower CSF-GABA for their age
during the pre-hypsarrhythmic period.
Significance:
This study will offer providers a powerful tool for screening/identification of susceptible individuals during the
predictive onset period of infantile spasms.
