Background: The role of maternal allergic disorders to increase the risk of Transient Tachypnea of Neonate (TTN) in neonates remained unclear. We determined the incidence of allergic disorders in first degree relatives of neonates suffered from TTN to clear role of these allergic disorders to predispose TTN in neonates.
Materials and Methods: In a cross-sectional study carried out at Fatemieh hospital between September 2010 and September 2011, all consecutive neonates with the diagnosis of TTN were included into the study. Those neonates were not treated after 5 days of hospitalization were excluded. Baseline information with regard to the history of allergic diseases among first degree relatives of neonates were charted from family members using a structured questionnaire at enrolment by interviewing and examination if required.
Results: The two groups were matched for baseline data including neonate gender, birth weight, and type of delivery. In the TTN group, one of first degree relatives (2.9%) suffered from bronchial asthma and two of them (5.7) had atopic dermatitis. In total, allergic diseases was revealed in 8.6% of first degree relatives of neonates with TTN. Besides, none of the first degree relatives of neonates in healthy neonates group experienced bronchial asthma or atopic dermatitis. Allergic rhinitis was not also found in the relatives of the two study neonates groups. Comparing incidence of allergic diseases in first degree relatives of neonates in TTN and healthy groups showed no significant difference (8.6% in TTN group versus 0.0% in healthy group, p = 0.076).
Conclusion: Our study showed that the incidence of allergic disorders in first degree relatives of neonates suffered from TTN is higher than healthy newborns, but these differences are not statistically significant.
