Protein-losing enteropathy in systemic lupus erythematosus associated with intestinal lymphangiectasia
Department of Medicine, University of Calgary, Alberta, Canada.
This case report concerns a young woman with systemic lupus erythematosus who presented with a protein-losing enteropathy. Intestinal biopsy revealed lymphangiectasia. Mesenteric lymph nodes showed paracortical lymphoid depletion and multiple small sinusoids. Elevated cholesterol levels and normal lymphocyte counts characterized the peripheral blood samples. Lymph nodes, though enlarged, showed no evidence of obstructive pathology. No secondary cause of lymphangiectasia could be identified. The patient exhibited antinuclear antibodies and antibodies to dsDNA at the onset, and then, 5 yr later, the classic features of systemic lupus erythematosus (SLE). The lymphocytopenia and hypolipidemia that characterizes lymphangiectasia is not a feature of the SLE cases reported to date. Furthermore, the mechanism for the dilated lymphatics and villous edema is more likely immunological than mechanical disruption of lymphatics.* * * * *

Protein-losing enteropathy is a rare manifestation of systemic lupus erythematosus (SLE) leading to hypoalbuminemia and anasarca. We report the case of a woman with SLE who presented chronic hypoalbuminemia diagnosed as protein-losing enteropathy associated with SLE. She was refractory to prednisone and azathioprine administration but showed good response to cyclophosphamide. The diagnosis and management of hypoalbuminemia in lupus-associated enteropathy are discussed.

Protein-losing enteropathy (PLE) is a rare manifestation of systemic lupus erythematosus (SLE), and it is an uncommon cause of hypoalbuminemia without proteinuria. We describe a case of an 11 year-old girl who had diarrhea and periorbital edema as the initial symptoms of SLE. PLE was diagnosed by 24-hour stool alpha-1 antitrypsin clearance and 99mTc-human serum albumin scintigraphy.
