We report an unusual case of systemic lupus erythematosus presented with protein-losing enteropathy. A 24-year-old girl was referred to our hospital with generalized edema, thrombocytopenia, hypoalbuminemia, hypercholesterolemia, hypocomplementemia, antinuclear antibody (ANA) (speckled pattern) and anti-SSA/Ro positivities, and elevated CA125 antigen appeared in the blood examination. On the radiological studies, she had mild pleural effusion and moderate ascites which were transudate. A diagnosis of protein-losing enteropathy was made on the basis of increased 99mTc-labelled human immunoglobulin scintigram showing abnormal radioactivity. Endoscopic gastric, duodenal and jejunal biopsies showed chronic inflammation, but vasculitis and immune complex deposition findings were not present. Renal biopsy revealed no definitive findings of lupus nephritis. By the administration of corticosteroids, hypoalbuminemia began to improve, but steroid doses were decreased due to steroid-induced myopathy. Temporary hemiparesis and facial paralysis developed in the patients' follow up. Her cranial magnetic resonance imaging revealed chronic ischemia, and the patient was considered to have neurological involvement due to systemic lupus erythematosus, protein-losing enteropathy and other symptoms then improved dramatically after monthly intravenous cyclophosphamide (three times) combined with oral low-dose corticosteroids. The combination of azathioprine and low-dose steroids was used as maintenance medication. Although about 30 protein-losing enteropathy -associated systemic lupus erythematosus cases have been reported, the patients having initial symptoms as protein-losing enteropathy are rare in the literature. Protein-losing enteropathy -associated systemic lupus erythematosus cases probably represent a subgroup of systemic lupus erythematosus, the characteristics of which are hypocomplementemia, protein-losing enteropathy, ANA positivity showing speckled pattern and anti-ds DNA negativities. In the patients with systemic lupus erythematosus with edema and hypoalbuminemia without renal protein loss, protein-losing enteropathy-associated systemic lupus erythematosus should be kept in mind.
