[Hypoparathyroidism associated with systemic lupus erythematosus: a case].

Unlabelled: Hypoparathyroidism is very rarely diagnosed in patients with lupus.

Case: A 39-year-old women had systemic lupus erythematosus known for 3 years. She was admitted for a paresthesia of the lower limb, depression, insomnia and 5 kg weight loss. The laboratory tests revealed hypoparathyroidism and no sign of disease activity. Treatment with oral calcium and vitamin D resulted in correction of the hypocalcemia and QT prolongation.

Discussion: The combined diagnosis lupus-hypoparathyroidism has very rarely been reported. We suggest there may be a common underlying pathological process linking the two diseases. The occurrence of these diseases in the same individual may be related to an underlying genetic predisposition or secondary to the generalized autoimmune disease process.
