title: Hydrallazine-induced Sjögren's syndrome.
abstract: 4 years after initiation of therapy with hydrallazine hydrochloride (for treatment of hypertension), a 60-year-old male patient developed clinical features of Sjögren's syndrome, with immunological features of drug-induced systemic lupus erythematosus. In addition, the patient described rheumatoid arthritis-like symptoms and had reduced lacrimal and parotid salivary flow, but lacked the typical features of Sjögren's syndrome on labial gland biopsy. 1 year after discontinuation of hydrallazine therapy, the clinical parameters returned to normal.
