Similarly, Tordjman et al. [77] noted a case of asymptomatic hypoparathyroidism in a 25-year-old mother during pregnancy; the patient presented with symptomatic hypocalcemia (5 mg/dL) shortly after a caesarean section, requiring hospitalization for 17 days and various calcium-vitamin D therapeutic combinations; of note, it appears that this patient did not lactate, in keeping with ‘nadir’ following PTHrP-placental removal. This evidence concerns the gene PTHLH and hypoparathyroidism.
