Decreased bone ultrasound velocity in premature infants conceived with assisted reproduction

Armangil D, Gürsoy T, Korkmaz A, Özyüncü Ö. Decreased bone ultrasound velocity in premature infants conceived with assisted reproduction. Turk J Pediatr 2015; 57: 17-25.Quantitative ultrasound (QUS) measurement of tibial speed of sound (SOS) can be used to determine bone strength. Children conceived with assisted reproduction treatments (ART) are taller than naturally conceived (NC) children, so we hypothesized that these infants would have higher SOS levels than NC infants. Thirty-seven ART (ART group) and 51 NC neonates (NC group) were included in the study. Tibial initial SOS (iSOS) was measured within 96 hours of birth using QUS. Measurements were performed weekly until the infant was discharged from the hospital. The iSOS levels of the ART group (2823.41±110.8 m/sec) were lower than those of the NC group (2917.14±145.6 m/sec) (p=0.001). A decrease in SOS levels was observed in 39 of 53 infants who had serial scans. The difference in SOS levels between the first and last scan was significant (p
