Primary hyperparathyroidism in pregnancy: a case series and literature review

Abstract

Primary Hyperparathyroidism (PHP) in pregnancy constitutes a serious danger to mother and fetus. The diagnosis of PHP in pregnancy presents a challenge, and PHP commonly goes unidentified and untreated in pregnancy. We present four case reports about patients having PHP, which is very rare condition in pregnancy and their treatment modalities. Three patients, not to be controlled biochemically, denied the parathyroidectomy operation although they are informed about the details of their disease. They are followed up with medical therapy. The first one had no maternal or fetal complications, the second one acquired nephrolithiasis crisis in the last trimester and the third one gave birth to a premature baby who succumbed to tetany. The fourth patient who underwent parathyroidectomy operation in the second trimester had no maternal or fetal complications. PHP in pregnancy is a preventable cause of fetal and maternal mortality and morbidity. Thus, suspecting from PHP during the pregnancy and early diagnosis is critically important in terms of maternal and fetal wellness.
