A 38-year-old Japanese woman, who had fulfilled the revised American College of Rheumatology criteria for systemic lupus erythematosus (SLE), and whose disease had been controlled with oral prednisolone at a dose of 5 mg/day for a year, reported a 3-day history of nausea and vomiting. On admission, laboratory tests showed a lactate dehydrogenase level of 610 IU/l, an erythrocyte sedimentation rate of 35 mm/hour, a positive antinuclear antibody (titer 1 : 40), and decreased levels of complements (C3, 32 mg/dl; C4, 6 mg/dl; CH50, 24.4 U/dl). Gastroscopic examination revealed a stenosis of the pyloric antrum with no mucosal lesion (Figure [1]). A computed tomographic scan demonstrated diffuse thickening of the antral wall with marked enhancement by contrast material on the serosal side (Figure [2]), in addition to mild hydronephrosis, thickened wall of the gallbladder, and a small amount of ascites. The lupus peritonitis and cholecystitis was thought to be the most likely cause of the antral stenosis.

The patient was treated with intravenous prednisolone at a dose of 20 mg/day and the symptoms subsided immediately. Endoscopic examination and a computed tomographic scan within 2 weeks after the introduction of intravenous steroids showed no evidence of antral wall thickening or stenosis. The patient has been free from symptoms over 1 year of follow-up.
Lupus peritonitis and cystitis is an unusual manifestation of SLE. In previously reported cases, involvement of the gut has been primarily in the small intestine [1] [2] [3] and rarely in the stomach [4] [5]. The finding in our patient indicates that serositis can occur focally on the gastric serosa in SLE, as shown previously at laparotomy [5], which results in stenosis of the pyloric antrum. A contrast computed tomography (CT) scan and endoscopic examination are useful for the differential diagnosis. Physicians should consider this unusual cause of antral stenosis which showed adequate remission with intravenous steroid.
