BEDOYA C, Elizabeth et al. Nefrocalcinosis como complicación de hipercalcemia por ingesta excesiva de calcio en el embarazo. Rev. chil. obstet. ginecol. [online]. 2016, vol.81, n.1, pp.44-47. ISSN 0717-7526.

Background: Hypercalcemia during pregnancy is a strange finding. The long exposure to high calcium levels can take to calcifications in different maternal organs and it can lead to miscarriage and stillborn. Case presentation: A woman with 20+4 weeks' gestation, who was remitted because of an acute renal failure and hypertension. She reported excessive intake of cheese, milk and multivitaminics. With a calcium level of 9.2 mg/dL and BUN/Creatinine of 6.8, diagnosed with food poisoning and medullary nephrocalcinosis as a result of the high calcium intake. At the fourth day at the hospital she presented vaginal bleeding and due to the conditions of the mother the pregnancy was ended. Afterwards she presented a significant clinical improvement and she was discharged from the hospital. Discussion: The relevance of this case is that the presence of hypercalcemia during pregnancy and not identifying it elevates the risk of miscarriage and neonatal hypocalcemia, which can cause maternal death. In this aspect, many complications can develop, being one of the most important the nephrocalcinosis, identified in this report. Conclusion: The excessive calcium intake in pregnant women can cause nephrocalcinosis. It is important to educate them to avoid this and other complications.
