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 ((99m)Tc-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.
An epidemiological investigation with Legionella and molecular subtyping was conducted to determine the source of a case of nosocomial Legionnaires' disease (LD) who was hospitalized in three hospitals within a month. Legionella pneumophila serogroup 3, an uncommon serogroup for infection, was isolated from the patient's sputum. Environmental surveillance revealed Legionella colonization in all three hospitals; the patient isolate matched the isolate from the first hospital by molecular typing. Culturing the hospital water supply for Legionella is a pro-active strategy for detection of nosocomial LD even in hospitals experiencing no previous cases.
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.
