A late-preterm infant with hypocalcemic tetany caused by traditional soy milk feeding: A case report and literature review

Abstract

Hypocalcemia may cause numerous symptoms, including neuromuscular irritability, prolonged QT interval, apnea, cyanosis, tachypnea, vomiting, or laryngospasm. Here, we reported a late-preterm 3-month-old infant presenting general involuntary twitches caused by hypocalcemic tetany. Laboratory data revealed hypocalcemia–hyperphosphatemia, high parathyroid hormone, normal magnesium, and low vitamin D(25-OH). Calcium intake deficiency was suspected. The infant was cured after calcium supplementation through the intravenous route and standard infant formula.
