Successful Long-term Treatment with Cyclosporin A in Protein Losing Gastroenteropathy

Abstract

Protein-losing gastroenteropathy (PLG) can occur as a manifestation of various diseases including autoimmune disorders, and optimal therapy of these underlying diseases may be the only effective remedy for PLG. In the present report, we describe a case of a 54-year-old woman with PLG associated with an autoimmune disease, presumably CREST syndrome. She failed to respond to steroid treatment. Subsequently, cyclosporine was initiated, which resulted in a rapid recovery. The patient was successfully treated with low-dose cyclosporine for five years. There has not been, to our knowledge, any report of PLG successfully treated with cyclosporine. Cyclosporine therapy may be effective not only in inducing but also in maintaining complete remission in patients with autoimmune-associated PLG, especially refractory or intolerable to steroids and/or immunosuppressive therapies.
