title: Primary Sjögren's syndrome with secondary hyperparathyroidism.
abstract: The case history of a 43-year-old woman with primary Sjögren's syndrome is presented: in 1970, xerostomia and keratoconjunctivitis sicca; in 1980, arthritis; in 1982, chronic tubulointerstitial nephritis with renal tubular acidosis and vasopressin-resistant hyposthenuria. The renal function gradually deteriorated. Chronic atrophic gastritis with vitamin B12 deficiency and chronic duodenitis with diminished disaccharidase activity in the mucosa were also diagnosed. From 1985, repeated multiple fractures of the ribs occurred, with secondary hyperparathyroidism in the background. The renal and intestinal involvement suggests that, besides the elevated parathyroid hormone level, an acquired vitamin D deficiency plays a pathogenetic role in severe osteopenia. The patient is being treated at present by haemodialysis, and subtotal parathyroidectomy and renal transplantation are planned.
