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.

We describe a case of adult T-cell leukemia (ATL) with intestinal infiltration. In the early clinical stage, the endoscopic findings for the intestine were similar to those of amebic enterocolitis, i.e., varioliform mucosal polypoid lesions, and amebic cyst was detected with stool examination. Although no specific pathological factor could be identified on biopsy, the patient was treated for amebiasis as a diagnostic therapy. The findings of varioliform mucosal polypoid lesions were detected in the duodenum on endoscopic examination, but the lesions eventually disappeared during the treatment for amebiasis. We then suspected lymphoma partially masked by the amebiasis. Immunological staining of a specimen of the colonic mucosa revealed T cell invasion and Southern blotting demonstrated adult T-cell leukemia provirus invasion. Thus, ATL cell infiltration of the intestinal tract was confirmed. It is suggested that systemic disease should also be considered when varioliform mucosal polypoid lesions are found on colonoscopic examination.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
