The article presents a case with a particular clinical situation that has associated an enteric neuropathy with an evolution of over two months, with a Guillain-Barré syndrome (Landry type), both remitted after plasmapheresis. A 53 year old male patient has been admitted in our Neurological Department with dehydration, syncope and orthostatic hypotention, due to an enteric neuropathie, complicated in 8 days with a Guillain Barré syndrome-GBS. This type of associated diseases is rarely described in the literature, being well known that GBS can be precede with two weeks in advance by a diarrheic episode. In our case, a chronic diarrheic sufferance was involved- an enteric neuropathy. Both types of neurological manifestations had an obvious improvement after plasmapheresis, suggesting an autoimmune process as common etiology.
