Two Concomitant Rare Extraglandular Manifestations of Primary Sjögren's Syndrome: IgA Nephropathy and Autoimmune Hepatitis.

Abstract

Primary Sjögren's syndrome (pSS) is a systemic autoimmune disease and can rarely present with multiple extraglandular manifestations. Here we report a case of pSS with concomitant IgA nephropathy and autoimmune hepatitis as the initial manifestations. She presented with polyarthralgia, sicca symptoms and persistent fatigue but was asymptomatic for renal and liver involvement. Autoimmune diseases can have overlapping clinical features and occasionally, manifest nonspecific symptoms leading to delay in diagnosis. It is therefore imperative to thoroughly evaluate any patient of pSS for early recognition of the diverse extraglandular features and initiate prompt treatment to improve outcome.
