Lithium-induced parathyroid dysfunction: A new case

C Gopalakrishnan Nair et al. Indian J Endocrinol Metab. 2013 Sep.

Abstract

Lithium salts are widely used in psychiatric practice and are known to induce thyroid dysfunction. Lithium-induced parathyroid dysfunction is rare. We are reporting a case of hyperparathyroidism in a 28-year-old female patient who was on lithium carbonate for 2 years, when she developed osteopenia and girdle girdle-type muscle weakness. Biochemical parameters showed hyperparathyroidism with shift of calcium creatinine clearance ratio to 0.013, indicating an error in threshold of calcium sensing receptor. The patient eventually required parathyroidectomy and the histology of the gland showed atypical features.

Keywords: Atypical adenoma; calcium sensing receptor; hyperparathyroidism; lithium.
