Serum and urinary trisaccharides in mannosidosis.

Abstract

A trisaccharide, Man2glcNAc, was the most abundant urinary oligosaccharide (161-558 mumol per liter) in a patient with mannosidosis. By means of a newly developed high-performance liquid chromatography (HPLC) procedure, we were able to measure low levels of serum trisaccharide (0.1--0.4 nmol per milliliter). This is the first report of the measurements of serum oligosaccharides in mannosidosis. Our observations on the disparate relationship between serum and urinary concentrations of this trisaccharide suggest that a facilitated renal clearance of oligosaccharides may be related to the nonprogressive aspect of this disorder.
