Amyloid A amyloidosis is an obstinate disease complication in chronic inflammatory disease, and there are few effective therapies. The objective of this study was to investigate the effect of oral dimethyl sulfoxide (DMSO) on amyloid A amyloidosis. Methods. Fifteen secondary amyloid A amyloidosis patients (4 men, 11 women; age, 23-70 years) were treated with DMSO between 1995 and 2003. DMSO was administered orally in all patients at a dose of 3-20g/day. The clinical symptoms together with the renal and gastrointestinal functions were evaluated before and after treatment. Results. Among the 15 patients, amyloid A amyloidosis was a complication of rheumatoid arthritis (RA) in 10, of Crohn’s disease in 4, and of Adult Still’s disease in 1. Nine cases mainly involved the kidney, with renal dysfunction and proteinuria, five mainly involved the gastrointestinal tract, with protein-losing gastroenteropathy and intractable diarrhea, and one involved both gastrointestinal and renal amyloidosis. DMSO treatment was successful in 10 (66.7%) of the 15 patients (RA, 6/10; Crohn’s disease, 4/4; Adult Still’s disease, 0/1). Eight weeks of DMSO administration improved the renal function and proteinuria in five out of ten renal amyloidosis patients, but had no effect on those patients with severe and/or advanced renal dysfunction. With regard to gastrointestinal amyloidosis, gastrointestinal symptoms, including diarrhea and protein-losing gastroenteropathy, were improved in six patients. No serious side effects were encountered with the DMSO treatment. Conclusions. Oral administration of DMSO is an effective treatment for amyloid A amyloidosis, especially for gastrointestinal involvement and the early stage of renal dysfunction.展开更多

Sixty-eight outpatients with gastroesophageal reflux-associated dysphagia were enrolled in this study. Endoscopic esophagitis was confirmed in 52 of 68 subjects. The proton pump inhibitor rabeprazole was administered at 20 mg daily for 8 weeks. Rabeprazole was administered for a further 6 months to 16 subjects whose dysphagia was improved (10 mg/day) and 5 of these underwent 24-hr esophageal pH monitoring before and after treatment. Dysphagia was completely resolved in 40 of 68 subjects, which were categorized in Group I. Dysphagia improved partially in 20 subjects and was unchanged in 8 subjects. These 28 subjects were categorized into Group II. Comparison was made between Group I and Group II and multivariate analysis demonstrated that the only factor that correlated with the effect of rabeprazole on dysphagia was “improvement in heartburn symptoms." There were no relapses of symptoms during the 6-month follow-up period, and pH monitoring showed sustained suppression of acid secretion.The results indicate that rabeprazole is effective in the treatment of dysphagia associated with gastroesophageal reflux disease. We were, however, unable to elicit any factors that could predict the therapeutic effect of rabeprazole before commencing treatment.展开更多
