Abstract

Primary hyperparathyroidism (PHPT) is the leading cause of hypercalcemia. Total serum calcium level >3.5 mmol/L is associated with a high risk of a hypercalcemic crisis, manifesting with nausea, vomiting, dehydration, myalgia’s, abdominal pain, acute pancreatitis, acute kidney injury (AKI), cardiac rhythm disorders and disturbances of consciousness. We report here a case of PHPT, manifested with hypercalcemic crisis during pregnancy. A 30-year-old woman in the first trimester of pregnancy admitted complaining on loss of appetite, nausea, vomiting, lower abdomen pain, weakness, and leg pain during the last 10 days. She had a history of two uncomplicated pregnancies, and two episodes of renal colic, her kidney function was normal 2 weeks prior to admission. Work-up showed hypochloremia, hypokalemia, hyponatremia, total serum calcium was 5.34 mmol/L, and serum creatinine 226 µmol/L, and she underwent urgent hemodialysis (HD). Her parathyroid hormone (PTH) was 948 pg/mL, and imaging revealed missed miscarriage 9-10 weeks, soft tissue mass 30x20x33mm near the lower pole of the left lobe of the thyroid gland, small stones in renal calices, and polysegmental pneumonia. She received antibiotics, calcimimetics, and every-day hemodiafiltration (HDF), and underwent vacuum aspiration of uterine cavity and surgical removal of the parathyroidoma. Her PTH shortly returned to the reference level, and serum creatinine dropped to 140 µmol/L after kidney replacement therapy (KRT) secession. Pathology confirmed the diagnosis of parathyroid adenoma. PHPT should be included in the diagnostic algorithm of AKI in pregnancy along with vomiting of pregnant, sepsis, pre-eclampsia and other causes. Successful management of PHPT complications in pregnancy demands multidisciplinary team.
