Case series of neonatal hypocalcemia due to pseudohypoparathyroidism

Four children; all between 10-40 days of age, were admitted with multiple episodes of multifocal seizure. After admission blood investigation was carried out and they were found to have hypocalcemia, hyperphosphatemia; kidney function tests were normal. Serum parathyroid hormone was highly elevated and serum magnesium level was found to be normal in these patients. The infants did not have any other features of pseudohypoparathyroidism. The seizure was initially resistant to intravenous calcium therapy and later responded to oral calcitriol and calcium therapy. The diagnosis of pseudohypoparathyroidism was made according to biochemical investigations. The infants were symptom-free during follow-up and the biochemistry reports were also normalized. One of the infants was also suffering from neonatal hepatitis, due to CMV infection.
