Hypokalemic paralysis due to primary Sjogren syndrome

Abstract

Sjögren syndrome is an autoimmune disorder characterized by lymphocytic infiltration of exocrine gland. The most common symptom by virtue of its involvement includes dryness of eyes, mouth, and parotid gland enlargement. However, the disease may be associated with extraglandular manifestation affecting multiple organs. Such a presentation involves renal involvement with tubular dysfunction manifesting as severe hypokalemia.
