Calcemia and Inflammatory Markers in Early-Onset Neonatal Infection
Introduction: Ionised hypocalcemia (S-Ca2+) has been repeatedly observed in neonates with sepsis. Our aim was to evaluate total calcemia (S-Ca) and its relationship to laboratory markers of infection. Methods: We retrospectively evaluated total calcemia (S-Ca) and its relationship to laboratory markers of sepsis/infection (serum levels of C-reactive protein – S-CRP and procalcitonin – S-PCT) in 29 full-term neonates with early-onset neonatal infection hospitalized at our neonatology ward between 2012 and 2016. The control group consisted of 705 neonates without infection. Results: In neonates with early-onset infection , the S-Ca on day 1, 2 and 3 was significantly lower (p < 0.0001; p < 0.0001; p = 0.05 versus controls) same as the pooled S-Ca (p < 0.0001 versus controls). There was a weak negative correlation between pooled S-Ca and S-PCT, or pooled S-Ca and S-CRP (r = −0.22, p = 0.06; r = −0.19, p = 0.09). Conclusion: S-Ca was decreased in neonates with early-onset infection and did show a slight tendency to inverse correlation with S-CRP and S-PCT. Pediatricians must be aware of the fact that a drop in total S-Ca should alert their attention to the risk of neonatal infection, and, likewise, that the children with neonatal infection are at a higher risk of hypocalcemia with all its consequences.
