Among gangliosidosis (Gang) patients (left-side charts), five CSF analytes of
inflammation were consistently elevated in patients with the infantile-onset
disease in contrast to the normal levels found in patients with juvenile-onset
disease. This relationship of severity of disease to analyte elevation is
important, this correspondence reflecting the rate of disease progression.
CSF and serum inflammatory biomarkers from patients with MPS diseases (right-side
charts) showed no abnormalities in either serum or CSF. The analyte differences
between gangliosidosis disease and MPS disease emphasize the value of these
inflammatory biomarkers, and illustrate that the analyte abnormalities are not
general indicators of lysosomal storage or dysfunction, but reflect some other
pathologic mechanism of gangliosidosis disease in the central nervous
system.
