Sjögren’s syndrome associated with protein losing gastroenteropathy manifested by intestinal lymphangiectasia successfully treated with prednisolone and hydroxychloroquine

Abstract

Protein-losing gastroenteropathy (PLGE), a rare manifestation of primary Sjögren’s syndrome (SS), is characterized by profound edema and severe hypoalbuminemia secondary to excessive serum protein loss from the gastrointestinal tract and is clinically indistinguishable from nephrotic syndrome. We report a case of a 30-year-old Taiwanese woman with PLGE-associated SS. In addition to a positive Schirmer’s test, she had eye-dryness, thirst, and high levels of anti-SSA antibodies, fulfilling SS criteria. PLGE diagnosis was highly appropriate given the clinical profile of hypoalbuminemia, hypercholesterolemia, pleural effusion, and ascites, with absent cardiac, hepatic, or renal disease. We were unable to perform technetium-99 m-labeled human serum albumin scintigraphy (^99mTc-HAS). However, the patient’s edema and albumin level improved dramatically in response to a 3-month regime of oral prednisolone followed by oral hydroxychloroquine.
