Severe systemic immune response syndrome, low plasma paraoxonase activity, and a new albumin species in a traumatized patient with Gaucher's disease

INTRODUCTION: Gaucher's disease (GD) is an inborn error, autosomal recessive lysosomal lipid storage disorder characterized by the lack of the enzyme glucocerebrosidase. We observed some abnormalities in the plasma of a traumatized patient with GD. CASE REPORT: We report of a traumatized patient with GD that developed a severe systemic immune response during the course of an extended hospital stay. Plasma paraoxonase (PON) activity was assayed and found to be extremely low possibly due to the existence of GD in this particular patient. Also, a potentially novel post-translational modification (PTM) of albumin was noticed in the patient's plasma that coincided with enzyme replacement therapy (ERT) with Cerezyme. CONCLUSIONS: The decreased plasma PON activity measured might be a contributive factor in the development of an accentuated systemic immune response in a traumatized patient with GD. A modified albumin species could serve as a biomarker for ERT in Gaucher patients.
