Virtually every system and organ can be affected by SLE. Gastrointestinal symptoms are com-mon in SLE patients, and more than half of them are caused by adverse reactions to medications and viral or bacterial infections. Though not as common as lu-pus nephritis, SLE-related gastrointestinal involvement is clinically important because most cases can be life-threatening if not treated promptly. Lupus mesenteric vasculitis is the most common cause, followed by pro-tein-losing enteropathy, intestinal pseudo-obstruction, acute pancreatitis and other rare complications such as celiac disease, inflammatory bowel diseases, etc. No specific autoantibody is identified as being associated with SLE-related gastroenteropathy. Imaging studies, particularly abdominal computed tomography scans, are helpful in diagnosing some SLE-related gastroen-teropathies. Most of these complications have good therapeutic responses to corticosteroids and immu-nosuppressive agents. Supportive measures such as bowel rest, nutritional support, antibiotics and proki-netic medications are helpful in facilitating functional recovery and improving the outcome.展开更多

Both IgG and IgM antibodies to CMV were positive in a serologic blood test. Upper gastrointestinal endoscopy showed multiple erosions throughout the body of the stomach, without enlarged gastric folds. Histological examination of the biopsy specimens indicated eosinophilic gastroenteritis and CMV infection. The patient had complete resolution without specific therapy for CMV in four weeks. An allergic reaction as well as CMV infection played important roles in the pathogenesis of this case.展开更多

Methods： Forty rats were randomly divided into a diabetic group and a control group, Gastric emptying and small intestine transit rates were measured and histologic and molecular changes in glutamatergic nerves in the ileal myenteric plexus were observed, mGluR5 receptor and EAAC1 transporter changes in the diabetic rats were studied using fluorescence immunohistochemistry and RT-PCR. Results：Eighteen weeks after the establishment of the diabetic rats model, gastric emptying and small intestine transit rates were found to be significantly delayed in the diabetic group when compared with the control group. The density of glutamatergic ganglia and neurons in the ileal myenterie plexus were significantly decreased in the diabetic group when compared with control group（P 〈 0.05） and the mGluR5 receptors and EAAC1 transporters were downregulated in the diabetic rats（P 〈 0.05）. Conclusion： Decreased glutamatergic enteric ganglia and neurons and decreased mGluR5 receptors and EAAC1 transporters in the intestinal myenteric plexus is one of the mechanisms of diabetic gastroenteropathy in rats.展开更多
