Secondary Renal Injury and Encephalopathy Syndrome Caused by Systemic Lupus Erythematosus With Overlapping Sjögren's Syndrome in Children: A Case Report.

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.
