BRENER DIK, Pablo H et al. Hypercalcemia and hypophosphatemia among preterm infants receiving aggressive parenteral nutrition. Arch. argent. pediatr. [online]. 2018, vol.116, n.3, pp.e371-e377. ISSN 0325-0075.

Introduction. Aggressive parenteral nutrition is the standard of care among very-low-birth weight preterm infants. However, in recent studies, its impact on short-term outcomes, has been evaluated. The objective was to compare the prevalence of hypercalcemia and hypophosphatemia among preterm infants receiving aggressive or standard parenteral nutrition. Methods. Observational, retrospective study comparing a group of preterm infants weighing less than 1250 grams who received aggressive parenteral nutrition with a historical control group. The prevalence of hypercalcemia was estimated and its association with aggressive parenteral nutrition was searched adjusting by confounders. The mean phosphate level was estimated for the control group by linear regression and was compared to the value in the other group. Results. Forty patients per group were included. The prevalence of hypercalcemia was higher in the group who received aggressive parenteral nutrition (87.5% versus 35%, p= 0.001). Aggressive parenteral nutrition was associated with hypercalcemia when adjusting by birth weight, intrauterine growth restriction, amino acid, and calorie intake (adjusted odds ratio: 21.8, 95% confidence interval |amp;#91;CI|amp;#93;: 3.7-128). The mean calcium level was different between both groups (p= 0.002). Infants who received aggressive parenteral nutrition had more sepsis without reaching statistical significance and the mean phosphate level was lower than that estimated for the control group (p= 0.04). The prevalence of hypophosphatemia in this group was 90% (95% CI: 76-97%). Conclusions. Our data show an association between hypercalcemia/hypophosphatemia and aggressive parenteral nutrition. It is recommended to frequently monitor calcium and phosphate levels since they might be associated with adverse clinical outcomes.
