Abstract
Systemic lupus erythematosus (SLE) and Sjögren's syndrome (SS) are chronic, multisystem disorders. When the two coexist, the manifestations become more complex and diverse, and early diagnosis and treatment are a key to improving the patient prognosis. However, to date, only scarce reports have been published, especially overlap syndrome. We review the diagnosis and treatment process of a case of acute renal injury and encephalopathy syndrome secondary to SLE with overlapping SS to gain a comprehensive understanding of the disease with review of the current literature.
