[Primary hyperparathyroidism with persistent hypercalcemia in pregnancy].
Parathyroidectomy is effective in avoiding complications of primary hyperparathyroidism (pHPT) during pregnancy, because in about 90% of cases, it is caused by parathyroid adenomas. We present a case of severe pHPT during pregnancy of unknown etiology and without detectable parathyroid adenoma so that surgery was not a therapeutic option. The patient was a 29-year-old gravida 1 who presented with pHPT at 11 weeks of gestation. Although her serum calcium levels were elevated throughout pregnancy (>3.05 mmol/l; reference range: 2.05-2.65), a vigorous premature infant was delivered at 35 weeks of gestation. The infant received calcium intravenously, vitamin D(3) orally and was fed with raw human milk (low phosphorus) to prevent hypocalcemia. The baby did not develop clinical signs of hypocalcemia. Her initial parathyroid hormone level was suppressed (1.1 pg/ml; reference range: 15-65) and was normal at the age of 8 weeks. She was discharged from hospital at 14 days of life. Her physical, cognitive and motor development was normal through infancy and early childhood. In conclusion, pHPT during pregnancy does not necessarily lead to fetal or neonatal morbidity or mortality.
