Abstract

In a man with Fabry disease, basal plasma glycosphingolipid (GSL) levels were determined by high-performance liquid chromatography (HPLC). A series of three alternate-day plasma exchanges transiently lowered plasma ceramide trihexoside (CTH) to normal. A total of 70 μmoles of CTH were removed by eight plasma exchanges. If future studies show that pathologic tissue accumulations of CTH are reduced by plasma exchange, then long-term repetitive plasma exchange could be used as treatment until enzyme replacement is practical.
