Objective: This thesis investigated the occurrence of hyperbilirubinemia in infants born to diabetic mothers. Because hyperbilirubinemia is a risk factor for hearing loss, the hearing status of these infants was also investigated by reviewing outcomes of hearing screenings. Methods: This was a retrospective study of 100 neonates’ medical charts that were screened for hearing status at Good Samaritan Hospital, Cincinnati, OH between January 1, 2000 and May 1, 2002. The subjects included infants born to mothers that are positive for pre-gestational diabetes. Information collected on hearing status include high-risk registry information, and Otoacoustic Emissions and Auditory Brainstem Response data. Results: Of the 100 neonates’ in this study, 6 of the infants were documented as hyperbilirubinemic (levels >5 mg/dl). The mean bilirubin level of 14 mg/dl (N=5) was found for the group. One infant was recorded as undergoing phototherapy, but no data regarding bilirubin levels was available. The hearing screening outcomes resulted in passes for those tested (N=5). Not all infants were tested with both OAE and ABR. Discussion: Hyperbilirubinemia occurred in 6% of our infants born to diabetic mothers. This is similar to the prevalence of 8.3% hyperbilirubinemia reported for non-diabetics (Jahrig et al., 1989). Birthweight was fairly normal for the hyperbilirubinemic group born to diabetic mothers. The normal birthweights may be indicative of an excellent health status for the diabetic mothers in our study. The health of the mothers may help to explain the low occurrence of hyperbilirubinemia in this population. It could indicate a higher amount of diabetic control, which may have resulted from the specialized prenatal care that diabetic mothers can receive at the high risk clinic at Good Samaritan Hospital. Some of the infants in this study had other hearing risk criteria, including family history (16%) and a stay in the NICU (33%). Hearing screening outcomes resulted in passed results for all infants that were tested, but not all infants were tested with both OAE and ABR. Due to hyperbilirubinemia causing neural lesions, all infants with hyperbilirubinemia should have OAE and ABR hearing screenings, in order to rule out the possibility of auditory deficits.
