Hemolytic-uremic syndrome (HUS) is usually preceded by enteric infection by Shiga-like toxin-producing Escherichia coli (SLT-EC), but most children with SLT-EC diarrhea do not develop HUS. SLT toxicity depends on entry into the target cell via its host cell glycolipid receptor, globotriaosylceramide (Gb3). The relationship between differential susceptibility to HUS and erythrocyte Gb3 levels, as measured by high-pressure liquid chromatography, was studied. Erythrocytes of children with histories of HUS had lower nonhydroxylated fatty acyl (NFA) Gb3 levels than did erythrocytes of controls (1.6 vs. 2.0 nmol/mL of packed cells); these erythrocytes had lower ratios of NFA-Gb3 to lactosylceramide (0.16) than did erythrocytes of SLT-EC diarrheal patients without subsequent HUS (0.30; P < .003) or of healthy controls (0.28; P < .001). The lower erythrocyte Gb3 levels associated with HUS may reflect a genetic predisposition for differential outcomes of SLT-EC gastroenteritis.
