[Celiac disease revealed by hypocalcemia complicating total thyroidectomy: a case report].
In order to illustrate a particular circumstance of diagnosis of celiac disease, we report the case of 54-year-old women with a history of thyroid enlargement with normal thyroid function and positive anti-peroxidase antibodies. Immediately after total thyroidectomy with preservation of the parathyroid glands, she developed tetany with total serum calcium level at 50mg/l. Intravenous calcium infusion increased the calcium level and led to resolution of hypocalcemia-induced signs but there was no result when calcium and vitamin D were taken orally. The diagnosis of malabsorption was very probable in light of the family history of celiac disease, the anemia and the hypoalbuminemia. The diagnosis was confirmed by antibodies assay and endoscopy. The PTH level was less than 1 pg/l and radiography showed signs of hyperparathyroidism. Gluten-free diet, calcium and vitamin D led to an improvement of serum calcium.
