Recurrent hemolytic uremic syndrome associated with intestinal lymphangiectasia.

A 17-year-old boy was admitted to the hospital twice in a year for 2 episodes of hemolytic uremic syndrome (HUS). During these 2 HUS episodes he had diarrhea, decreased serum complement, decreased total protein and decreased serum albumin concentrations. We suggest that protein-losing enteropathy and hypocomplementemia due to intestinal lymphangiectasia is may be a rare cause of atypical HUS.
